[0027] The following is an explanation of the implementation of the present application by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification.

[0028] Although the term first, second etc. is used to describe various elements or parameters in this article in some instances, these elements or parameters should not be limited by these terms.These terms are only used to distinguish one or parameter part from another or parameter.For example, the first direction can be referred to as the second direction, and similarly, the second direction can be referred to as the first direction, and for example, the first cutting device can be referred to as the second cutting device, and similarly, the second cutting device can be referred to as the first cutting device, without departing from the scope of the various described embodiments.

[0029] The relevant silicon rod processing operations involve several processes such as cutting, squaring, grinding, chamfering, etc.

[0030] Generally, most of the existing silicon rods are cylindrical structures. The silicon rods are cut and squared by silicon rod squaring equipment, so that the cross-section of the silicon rods after cutting and squaring is rectangular (including square), that is, the cut and squared silicon rods are rectangular (also cube-like) as a whole. The rectangular-like rectangles include rectangles with orthogonal adjacent sides or with angles within a predetermined angle, rectangles with rounded corners between adjacent sides, rectangles with short connecting sides between adjacent sides, etc.

[0031] Taking a single crystal silicon rod as an example, in some related technologies, the process of forming a single crystal silicon rod may include: first using a silicon rod cutter to slice the original long silicon rod to form multiple short silicon rods; after the cutting is completed, using a silicon rod squarer to cut and square the short silicon rod to form a single crystal silicon rod with a rectangular cross section. Among them, the specific implementation method of using a silicon rod cutter to slice the original long silicon rod to form multiple short silicon rods can refer to patent disclosures such as CN105856445A and CN105946127A, and the specific implementation method of using a silicon rod squarer to cut and square the short silicon rod to form a single crystal silicon rod with a rectangular cross section can refer to patent disclosures such as CN105818285A. However, the process for forming a single crystal silicon rod is not limited to the aforementioned technology. In an optional example, the process for forming a single crystal silicon rod may also include: first using a full silicon rod squaring machine to cut and square the original long silicon rod to form a long single crystal silicon rod with a rectangular cross-section; after the squaring is completed, using a silicon rod cutting machine to slice the cut and squared long single crystal silicon rod to form short silicon rods.

[0032] After the cylindrical single crystal silicon rod is cut and squared into a rectangular silicon rod by using a squaring device, the rectangular silicon rod can be ground and chamfered (or rounded) by using a grinding device. The specific implementation of the grinding and chamfering (or rounding) operations on the rectangular silicon rod by the grinding device can refer to patent disclosures such as CN105835247A.

[0033] Among them, in the silicon rod squaring operation, the silicon rod will form edge skin after squaring. We can call the edge skin formed after the silicon rod is cut and squared as edge skin rod, and the edge skin rod has a certain length, which is the same length as the original silicon rod, and its cross-section is generally arched (including the bottom side and the inferior arc line), that is, the edge skin rod includes: a rectangular bottom surface and an inferior arc surface opposite to the bottom surface. In some implementations, the edge skin rod is generally returned to the furnace or used as a polycrystalline ingot seed crystal, etc., but this results in a low utilization rate of single crystal silicon rods. In some implementations, the edge skin rod is cut into edge skin sheets with a rectangular cross-section for reuse, but this still has problems such as complex cutting equipment and low cutting efficiency.

[0034] In view of this, the first aspect of the present application proposes a skinning assembly line system.

[0035] The edge skin assembly line operation system includes an arc top cutting device, a stacking device, a cutting device, and an ear cutting device. The arc top cutting device is used to perform arc top cutting operations on the edge skin rod to cut off the arc top of the edge skin rod. The stacking device is used to stack multiple edge skin rods with the arc tops cut off to form an edge skin rod stack. The cutting device is used to cut the edge skin rod stack to form multiple edge skin rod stack segments. The ear cutting device is used to perform ear cutting operations on the edge skin rod stack segments to cut off the ears of each edge skin rod in the edge skin rod stack segments. In this way, the edge skin rod with an arched cross-section can be processed to form an edge skin sheet with a rectangular cross-section. Through assembly line operation, the processing efficiency and reuse of the edge skin rods are improved, saving resources and costs.

[0036] In the embodiments provided in the present application, in order to clarify the definition of direction and the mode of operation between different structures, a three-dimensional space defined by a first direction, a second direction, and a third direction is defined. The first direction, the second direction, and the third direction are all straight directions and are perpendicular to each other. The first direction and the second direction can form a horizontal plane, and the third direction is a vertical direction perpendicular to the horizontal plane, which can also be called a perpendicular direction, a vertical direction, an up-down direction, or a lifting direction.

[0037] In the embodiment provided in the present application, the cross-section of the edge skin rod is arched, including a rectangular bottom surface and a minor arc surface opposite to the bottom surface. The end face of the edge skin rod refers to two opposite surfaces along the length direction of the edge skin rod, and its two end faces are arched.

[0038] See also Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the whole of the edge skin assembly line system in one embodiment of the present application. Figure 2 Display as Figure 1 Schematic diagram of the status of each process involved in the middle edge skin assembly line operation system performing related operations on the edge skin sticks.

[0039] like Figure 1 As shown, a silicon rod cutting and grinding machine disclosed in an embodiment of the present application includes: an arc top cutting device 11, a stacking device 13, a truncation device 15, and an ear cutting device 17.

[0040] The arc top cutting device is used to perform arc top cutting operation on the edge skin bar to cut off the arc top of the edge skin bar. Figure 3 , displayed as Figure 1 Schematic diagram of the structure of the middle arc top cutting equipment. Figure 1 and Figure 3In the illustrated embodiment, the arc top cutting device 11 is used to perform an arc top cutting operation on the edge leather rod along the width direction of the edge leather rod to cut off the arc top of the edge leather rod. After cutting off the arc top of the edge leather rod, the edge leather rod with the arc top cut off forms a top surface with a smaller width and a bottom surface with a larger width, and ears with curved surfaces on both sides between the top surface and the bottom surface.

[0041] In some embodiments, the arc top cutting device includes: a first edge skin supporting device and a first cutting device, wherein the first edge skin supporting device is used to support an edge skin rod, and the first cutting device is used to perform an arc top cutting operation on the edge skin rod supported by the first edge skin supporting device to cut off the arc top of the edge skin rod. The cross section of the edge skin rod here is arched, including a rectangular bottom surface and a lower arc surface opposite to the bottom surface. Figure 1 and Figure 3 In the illustrated embodiment, the arc top cutting device 11 comprises: a first edge skin carrying device 111 and a first cutting device 113 .

[0042] Generally, the implementation method of using the first cutting device to perform an arc top cutting operation on the edge skin rod carried by the first edge skin bearing device to cut off the arc top of the edge skin rod includes using the first cutting device and the first edge skin bearing device to produce relative movement to perform the arc top cutting operation. In some embodiments, the first edge skin bearing device is a fixed edge skin bearing device and the first cutting device is a mobile cutting device. When performing the arc top cutting operation, the first cutting device is driven to move, that is, the first cutting device moves relative to the first edge skin bearing device and the edge skin rod carried by it. In some embodiments, the first edge skin bearing device is a mobile edge skin bearing device and the first cutting device is a mobile cutting device. When performing the arc top cutting operation, the first cutting device is driven to move and the first edge skin bearing device is driven to move respectively, that is, the first cutting device and the first edge skin bearing device and the edge skin rod carried by it move toward each other. In some embodiments, the first edge skin supporting device is a mobile edge skin supporting device and the first cutting device is a fixed cutting device. When performing arc top cutting operation, the first edge skin supporting device is driven to move, that is, the first edge skin supporting device and the edge skin rod it carries move relative to the first cutting device.

[0043] In some embodiments, the first edge skin supporting device includes at least one first edge skin supporting component. In some implementations, the first edge skin supporting component may be fixed, that is, the first edge skin supporting component in the first edge skin supporting device is fixedly arranged in the first cutting area. In some implementations, the first edge skin supporting component is movable, for example, the first edge skin supporting component in the first edge skin supporting device is provided with a rotating pivot, and the rotating pivot can drive the associated first edge skin supporting component to switch between the first cutting area and other working areas, and the other working areas may include one or more, for example, the other working areas may include a loading area, an unloading area, or a loading and unloading area, etc., and for another example, the other working areas may include a loading area and an unloading area, etc.

[0044] In some embodiments, the first side skin bearing device includes at least two first side skin bearing assemblies, and the at least two first side skin bearing assemblies are converted between different working areas through a conversion mechanism. For example, in some embodiments, the first side skin bearing device includes two first side skin bearing assemblies, and the two first side skin bearing assemblies can be arranged at a certain angle. For example, the working area may include a loading area and a first cutting area, and the loading area and the first cutting area are arranged relative to each other, and the two first side skin bearing assemblies can be arranged at 180°. A conversion mechanism is set between the two first side skin bearing assemblies, so that when one first side skin bearing assembly is located in the loading area, the other first side skin bearing assembly is located in the first cutting area, and the conversion mechanism is converted by ±180°, so that the two first side skin bearing assemblies can be driven to convert between the loading area and the first cutting area. For another example, the working area may include a loading area and a first cutting area, the loading area and the first cutting area are arranged at 90°, the two first side skin bearing assemblies may be arranged at 90°, and a conversion mechanism is arranged between the two first side skin bearing assemblies, so that when one first side skin bearing assembly is located in the loading area, the other first side skin bearing assembly is located in the first cutting area, and the two first side skin bearing assemblies can be driven to switch between the loading area and the first cutting area by converting ±90° through the conversion mechanism. The loading area is only an exemplary description, for example, in other embodiments, the loading area may also be, for example, a loading and unloading area, an unloading area or other working area. The setting angle of the loading area and the first cutting area may also be changed differently, and the angle may also be, for example, 100°, 110°, 120°, 130°, 140°, 150° or other angles, which are not limited here. In addition, the working area is not limited to one, and may also include two, three, or more. For example, the working area may include a loading area, a first cutting area, and an unloading area, and the three working areas are arranged at an angle (e.g., 90°, 120°, etc.), so that the first side skin bearing assembly is driven to switch between the various working areas by switching ±90° or ±120° through a conversion mechanism. In some implementations, the conversion mechanism may be, for example, a rotating pivot driven by a motor.

[0045] In such Figure 1 and Figure 3 In the illustrated embodiment, the working area includes a loading and unloading area and a first cutting area which are arranged opposite to each other (arranged at 180°), and the first side skin supporting device 111 includes two first side skin supporting components 1111 which are arranged opposite to each other (arranged at 180°), and the two first side skin supporting components 1111 are converted between the loading and unloading area and the first cutting area via a conversion mechanism 1112.

[0046] Regarding the first side skin bearing assembly, the first side skin bearing assembly may include one or more first side skin bearing units, each of which may be used to bear at least one side skin rod. For example, in some embodiments, the first side skin bearing assembly may include a plurality of first side skin bearing units arranged in a vertical layered manner, wherein each first side skin bearing unit may be used to bear at least one side skin rod. For example, the side skin bearing assembly may include three, four, five, or six first side skin bearing units arranged in a vertical layered manner, and each first side skin bearing unit may bear one, two, or more side skin rods. For example, each first side skin bearing unit may bear two side skin rods, and the two carried side skin rods are placed on the first side skin bearing unit in a left-right parallel manner.

[0047] In such Figure 1 and Figure 3 In the illustrated embodiment, the first side skin bearing assembly 1111 includes a plurality of (for example, three, four, five, or six, etc.) first side skin bearing units arranged in layers vertically (i.e., the third direction), each first side skin bearing unit carries two side skin rods 100, and the two side skin rods 100 are arranged in parallel on the left and right sides.

[0048] The first edge skin bearing unit may include a first edge skin bearing platform, the length of the first edge skin bearing platform may be related to the length of the edge skin rod, and the width of the first edge skin bearing platform may be related to the width of the edge skin rod. Still taking the example of two edge skin rods being placed on the first edge skin bearing platform in a left-right parallel manner, the length of the first edge skin bearing platform matches the length of the edge skin rod, and the width of the first edge skin bearing platform matches the sum of the widths of the two edge skin rods.

[0049] In order to place the edge skin bar firmly on the first edge skin supporting platform, the first edge skin supporting unit may further include a first edge skin positioning mechanism for positioning the edge skin bar carried by the first edge skin supporting platform. In this way, when the first cutting device is used to perform arc top cutting on the edge skin bar carried by the first edge skin supporting platform, the first edge skin positioning mechanism can be used to position the edge skin bar carried by the first edge skin supporting platform, so as to avoid relative displacement between the edge skin bar and the first edge skin supporting platform or relative displacement between the cut arc top and the edge skin bar during the arc top cutting operation, thereby affecting the cutting quality. In some embodiments, the first side skin positioning mechanism may be, for example, a side skin clamping mechanism. For a side skin rod, the side skin clamping mechanism may include two clamping jaws or clamping blocks arranged along the width direction of the side skin rod and a driving source for driving the clamping jaws or clamping blocks. When in use, the side skin rod is placed in the placement space between the two clamping jaws or clamping blocks, and the driving source is used to drive the two clamping jaws or clamping blocks to move or actuate toward each other along the width direction of the side skin rod to clamp the side skin rod located therebetween. Alternatively, for two edge skin bars arranged in parallel left and right, the first edge skin positioning mechanism may include a backrest, two clamping claws or clamping blocks, and a driving source for driving the clamping claws or clamping blocks, wherein the backrest is centrally arranged, and the two clamping claws or clamping blocks are arranged on opposite sides of the backrest along the width direction of the edge skin bar. When in use, the two placed edge skin bars are respectively located in two placement spaces formed by the backrest and the two clamping claws or clamping blocks on both sides, and the two clamping claws or clamping blocks are driven by the driving source to move toward or actuate along the width direction of the edge skin bar to cooperate with the central backrest to clamp the two edge skin bars located therebetween. In some embodiments, the first edge skin positioning mechanism may be, for example, an edge skin clamping mechanism. For one edge skin bar, the edge skin clamping mechanism may include a top clamping block and a driving source for driving the top clamping block. When in use, the edge skin bar is placed on the first edge skin supporting platform, and the driving source is used to drive the top clamping block to descend along a third direction to clamp the edge skin bar located thereunder.

[0050] In some embodiments, the first edge skin supporting platform may have a suction cup for adsorbing the bottom surface of the edge skin rod after the edge skin rod is placed.

[0051] The first cutting device is used to perform an arc top cutting operation on the edge skin rod carried by the first edge skin carrying device to cut off the arc top of the edge skin rod.

[0052] In some embodiments, the first cutting device includes a first cutting mounting structure and a first cutting unit, wherein the first cutting unit is disposed on the first cutting mounting structure and corresponds to the first side skin bearing unit in the first side skin bearing assembly of the first side skin bearing device, so as to perform arc top cutting operation on the side skin rod carried by the first side skin bearing unit.

[0053] Generally, for the first cutting device, a cutting machine base is also included, which is used to set the first cutting installation structure and the first cutting unit. The cutting machine base serves as the main component of the first cutting device. In some examples, the cutting machine base is large in size and weight to provide a large mounting surface and a firm stability of the whole machine. It should be understood that the cutting machine base can be used as a base for different structures or components that perform processing operations in the first cutting device, and the specific structure of the cutting machine base can be changed based on different functional requirements or structural requirements. In some examples, the cutting machine base includes a fixed structure or a limiting structure such as a base, a rod body, a column, a frame, etc. for receiving different components in the silicon rod cutting and grinding machine, which are all the cutting machine bases described in this application. At the same time, in some examples, the cutting machine base can be an integrated base, and in some examples, the cutting machine base can include multiple independent bases.

[0054] The first cutting installation structure is arranged on the cutting machine base and corresponds to the first cutting area. Figure 1 and Figure 3 In the illustrated embodiment, the first cutting mounting structure 1131 is disposed on the cutting machine base and corresponds to the first cutting area. In some embodiments, the first cutting mounting structure may be, for example, a mounting bracket, a mounting beam, a mounting column, or the like.

[0055] As mentioned earlier, in Figure 1 and Figure 3 In the embodiment, the first side skin bearing assembly 1111 includes a plurality of first side skin bearing units arranged in vertical layers, each first side skin bearing unit can carry at least one side skin rod 100, and accordingly, the first cutting device includes a plurality of first cutting units 1132 arranged in vertical layers and corresponding to the plurality of first side skin bearing units in the first side skin bearing assembly 1111.

[0056] The first cutting unit comprises: a plurality of first cutting wheels and a first cutting wire. Figure 1 and Figure 3 In the illustrated embodiment, the first cutting unit 1132 includes: a plurality of first cutting wheels 1133 and a first cutting wire 1134 . The first cutting wire 1134 is wound around the plurality of first cutting wheels 1133 to form at least one first cutting wire saw 1135 .

[0057] The first cutting wheel 1133 is provided with at least one cutting wire groove for winding the first cutting wire 1134. The cutting wire groove can define the position of the first cutting wire to control the cutting accuracy. Any first cutting wire saw 1135 is formed by winding the first cutting wire 1134 between two first cutting wheels 1133. The positions of the two first cutting wheels 1133 and the positional relationship between the first cutting wheels 1133 can be used to determine the direction of the first cutting wire saw 1135.

[0058] In such Figure 1 and Figure 3 In the illustrated embodiment, at least one first cutting wire saw 1135 is located in the first direction, and correspondingly, the wheel surface of at least one first cutting wheel 1133 is parallel to the first direction and the second direction, that is, the wheel surface of at least one first cutting wheel 1133 is located in a horizontal plane formed by the first direction and the second direction.

[0059] like Figure 1 and Figure 3 As shown, for example, in some embodiments, the first cutting assembly includes a plurality of first cutting units, and any first cutting unit 1132 includes a plurality of first cutting wheels 1133, for example, four first cutting wheels 1133, a first cutting wheel 1133a, a first cutting wheel 1133b, a first cutting wheel 1133c, and a first cutting wheel 1133d, the wheel surfaces of the four first cutting wheels 1133 are all located in a horizontal plane and form a quadrilateral (for example, a rectangle, a trapezoid, etc.) as a whole, wherein the first cutting wheel 1133a and the first cutting wheel 1133b are in the front (relatively closer to the loading and unloading area). The first cutting wheel 1133c and the first cutting wheel 1133d are arranged in parallel in the first direction at the rear (relatively farther from the loading and unloading area) and in parallel in the first direction. The first cutting wire 1134 is wound around the first cutting wheel 1133a, the first cutting wheel 1133b, the first cutting wheel 1133c, and the first cutting wheel 1133d to form at least one first cutting wire saw 1135 (for example, the first cutting wire saw 1135 is formed between the first cutting wheel 1133a and the first cutting wheel 1133b), and the at least one first cutting wire saw 1135 is arranged in the first direction. In addition, in order to enable the at least one first cutting wire saw 1135 to effectively cut the edge skin bar 100 to be cut, the at least one first cutting wire saw 1135 must interfere with the edge skin bar 100 to be cut in the third direction, that is, the at least one first cutting wire saw 1135 corresponds to the arc top of the edge skin bar 100 to be cut in the third direction.

[0060] In some embodiments, the first cutting line is wound between the first cutting wheels in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line). Figure 1 and Figure 3 In the illustrated embodiment, the first cutting line 1134 is wound around four first cutting wheels 1133 in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line).

[0061] The multiple first cutting wheels in the first cutting unit are wound by an annular cutting wire. In this example, the arc top cutting device can omit the wire storage drum. The annular cutting wire is driven by the cutting wire driving device to maintain high-speed operation. At the same time, the annular cutting wire can run in the same direction during the cutting operation (the traditional non-annular cutting wire with a wire storage drum runs alternately in forward and reverse directions). In this way, the arc top cutting device can achieve high-precision cutting operations, avoiding problems such as ripples on the cutting surface caused by the reversal of the cutting wire or the running speed in the existing cutting method; at the same time, the annular cutting wire can effectively reduce the total length of the cutting wire required for the arc top cutting device, thereby reducing production costs.

[0062] In some embodiments, the cutting line driving device is a motor having a power output shaft and the power output shaft is connected to a first cutting wheel, so that the first cutting line can be driven by the wound first cutting wheel to run along the winding direction. Of course, in a specific implementation, the cutting line driving device can also be another driving source such as a hydraulic motor, as long as it can drive the cutting line to run, and this application does not limit it.

[0063] The first cutting assembly in the present application may further include a first transition wheel, which is used to change the direction or guide the first cutting line, or the first transition wheel may be used to adjust the tension of the first cutting line. The number of the first transition wheels may be one or more according to layout requirements.

[0064] The first transition wheel, while guiding and pulling the first cutting line, also serves as a tension wheel for adjusting the tension of the first cutting line. The tension wheel is used to adjust the tension of the first cutting line, which can reduce the probability of the first cutting line breaking and reduce consumables.

[0065] like Figure 1 and Figure 3As shown, for example, in some embodiments, the first cutting assembly includes a plurality of first cutting wheels and a plurality of first transition wheels, for example, a first cutting wheel 1133a, a first cutting wheel 1133b, a first transition wheel 1136a, and a first transition wheel 1136b, the wheel surfaces of the first cutting wheel 1133a, the first cutting wheel 1133b, the first transition wheel 1136a, and the first transition wheel 1136b are all located in a horizontal plane and form a quadrilateral (for example, a rectangle, a trapezoid, etc.) as a whole, wherein the first cutting wheel 1133a and the first cutting wheel 1133b are in the front (relatively closer to the front). The first transition wheel 1136a and the first transition wheel 1136b are arranged in parallel along the first direction at the rear (relatively farther from the loading and unloading area) and in parallel along the first direction. The first cutting wire 1134 is wound around the first cutting wheel 1133a, the first cutting wheel 1133b, the first transition wheel 1136b, and the first transition wheel 1136a to form at least one first cutting wire saw 1135 (for example, the first cutting wire saw 1135 is formed between the first cutting wheel 1133a and the first cutting wheel 1133b), and the at least one first cutting wire saw 1135 is arranged along the first direction. In addition, in order to enable the at least one first cutting wire saw 1135 to effectively cut the edge leather bar 100 to be cut, the at least one first cutting wire saw 1135 must interfere with the edge leather bar 100 to be cut in the third direction, that is, the at least one first cutting wire saw 1135 corresponds to the arc top of the edge leather bar 100 to be cut in the third direction.

[0066] As described above, the first cutting wire is wound around multiple first cutting wheels or multiple first cutting wheels and multiple first transition wheels to form a first cutting wire saw 1135 between the first cutting wheels (for example, between the first cutting wheel 1133a and the first cutting wheel 1133b). Therefore, to adjust the wire length of the first cutting wire saw 1135, it can be achieved by adjusting the spacing between the first cutting wheel 1133a and the first cutting wheel 1133b, and the implementation method includes changing the position of at least one of the first cutting wheels 1133a and the first cutting wheel 1133b.

[0067] In addition, the first cutting wire saw can still have other changes. Figure 1 and Figure 3In the illustrated embodiment, the first cutting wheel 1133a and the second cutting wheel 1133b are arranged in parallel along a first direction, and the first cutting line 1134 is wound around a plurality of first cutting wheels 1133 or a plurality of first cutting wheels 1133 and a plurality of first transition wheels 1136 to form a first cutting wire saw 1135 between the first cutting wheels 1133 (for example, between the first cutting wheel 1133a and the first cutting wheel 1133b). The first cutting wire saw 1135 is arranged along the first direction, but is not limited to this. In other embodiments, the position of the first cutting wire saw 1135 may be located in a horizontal plane and arranged at an angle to the first direction with respect to the first direction, and the horizontal plane is composed of the first direction and the second direction, and the angle to the first direction is less than or equal to 45° (≤±45°), that is, the routing direction of the first cutting wire saw 1135 may be located in the same horizontal plane as the first direction and form an angle less than or equal to 45° (≤±45°) with respect to the first direction. In this implementation, in the second direction, one of the first cutting wheel 1133a and the first cutting wheel 1133b is in front and the other is in the back, for example, the first cutting wheel 1133a is in front and the first cutting wheel 1133b is in the back (the deflection angle formed by the first cutting wire saw with the first cutting wheel 1133a in front and the first cutting wheel 1133b in the back and the first direction is called a positive deflection angle) or the first cutting wheel 1133b is in front and the first cutting wheel 1133a is in the back (the first cutting wheel 1133a is in the back and the first cutting wheel 1133b is in the back) The deflection angle formed by the first cutting wire saw formed by the cutting wheel 1133b in front and the first direction is called a negative deflection angle). In this way, when cutting the top of the arc, the front part of the first cutting wire saw 1135 enters the edge skin bar 100 first and the rear part of the first cutting wire saw 1135 enters the edge skin bar 100 later during the advancement process, and continuously cuts the edge skin bar 100. Finally, the front part of the first cutting wire saw 1135 exits the edge skin bar 100 first and then the rear part of the first cutting wire saw 1135 exits later, until the top of the arc of the edge skin bar 100 is cut off. The deflection angle of the first direction can be changed according to the cutting process requirements and the size specifications of the edge skin bar to be cut. For example, the angle of the deflection angle of the first direction can be adjusted by changing the position of one or both of the first cutting wheel 1133a and the first cutting wheel 1133b related to the first cutting wire saw 1135.

[0068] In some embodiments, the first cutting assembly further includes a tension adjustment mechanism. In the wire cutting process, the cutting wire tension affects the yield and processing accuracy of the cutting process, and the tension adjustment mechanism detects the tension and adjusts the tension so that the cutting wire tension reaches a certain threshold value and maintains a constant value during cutting or takes the constant value as a certain range allowed by the center of the value.

[0069] In some embodiments, the tension adjustment mechanism is associated with a transition wheel, and the transition wheel in the wire cutting unit serves as a tension wheel for adjusting the tension of the cutting wire while achieving the guiding and traction of the cutting wire.

[0070] The tension wheel is used to adjust the tension of the cutting wire, which can reduce the probability of the cutting wire breaking and reduce consumables. In the cutting operation, the cutting wire plays a vital role, but even the best cutting wire has limited elongation and wear resistance, which means that the cutting wire will gradually become thinner during continuous operation until it is finally broken. Therefore, current wire cutting equipment generally has a cutting wire tension compensation mechanism to compensate for the elongation of the cutting wire during its reciprocating movement, and the use of a tension wheel is one means of implementation.

[0071] For example, in some embodiments, the tension adjustment mechanism can perform tension detection and adjust the tension according to the tension detection result. The method of adjusting the tension is not limited, for example, it can be achieved by adjusting the first transition wheel. In some cases, when it is detected that the tension does not reach the set requirement, the position of at least one of the two first transition wheels is adjusted, for example, the first transition wheel is moved outward, the circumference enclosed by each first cutting wheel and each first transition wheel is expanded, and the tension is increased. In some cases, when it is detected that the tension exceeds the set requirement, the position of at least one of the two first transition wheels is adjusted, for example, the first transition wheel is moved inward, the circumference enclosed by each first cutting wheel and each first transition wheel is reduced, and the tension is reduced.

[0072] In some embodiments, the first cutting assembly may further include: at least one first distance adjustment mechanism, for driving the plurality of first cutting wheels to move relative to the first cutting mounting structure in a direction perpendicular to the cutting wheel surface.

[0073] The first cutting assembly can realize the switching of the first cutting wire between different cutting grooves of the first cutting wheel based on the first distance adjustment mechanism, or adjust the position of the first cutting wire saw (for example, in the third direction) to change the cutting position (or processing specifications) relative to the silicon rod. In practical applications, the first distance adjustment mechanism may, for example, include: a screw, which is arranged along the orthogonal direction of the wheel surface of the first cutting wheel and is threadedly connected to the first cutting wheel; a driving source for driving the screw to rotate. Alternatively, the first distance adjustment mechanism may, for example, include: a telescopic member, which is arranged along the orthogonal direction of the wheel surface of the first cutting wheel and is associated with the first cutting wheel; a driving source for driving the telescopic member to perform telescopic movement along the orthogonal direction of the wheel surface of the first cutting wheel. Alternatively, the first distance adjustment mechanism may, for example, include: a rack, which is arranged on the first cutting wheel along the orthogonal direction of the wheel surface of the first cutting wheel; a transmission gear, which is meshed with the rack; and a driving source for driving the transmission gear to rotate.

[0074] In some implementations, the first cutting device is a mobile cutting device, and therefore, the first cutting device further comprises: a cutting installation structure driving mechanism, which is used to drive the first cutting installation structure and the plurality of first cutting units provided therein to move relative to the first edge skin bearing device. Figure 1 and Figure 3 In the illustrated embodiment, the first cutting device 113 further includes a cutting installation structure driving mechanism 1137 for driving the first cutting installation structure 1131 and the plurality of first cutting units 1132 thereof to move along the second direction.

[0075] In some embodiments, the cutting installation structure driving mechanism includes: a movable guide rail and a movable driving unit. The movable guide rail is arranged along the second direction and is used to set the first cutting installation structure. The movable driving unit is used to drive the first cutting installation structure and at least one first cutting unit provided therein to move along the movable guide rail.

[0076] In some embodiments, the mobile drive unit includes a mobile rack, a driving gear, and a driving source. The mobile rack is arranged along the second direction and is parallel to the mobile guide rail. The driving gear is arranged on the first cutting mounting structure and meshes with the mobile rack to drive the first cutting mounting structure to move along the mobile guide rail. The driving gear is driven to rotate by the driving source, and the gear teeth of the driving gear mesh with the mobile rack and move in accordance with the movement of the mobile rack, thereby causing the first cutting mounting structure connected to the driving gear to move accordingly on the mobile guide rail. The driving source is, for example, a driving motor.

[0077] In some embodiments, the mobile drive unit may be arranged on the first cutting installation structure, and includes a mobile screw and a drive source, wherein the mobile screw is arranged along the second direction and is associated with the first cutting installation structure, and the drive source is used to drive the mobile screw to rotate so that the associated first cutting installation structure and at least one first cutting unit arranged therein move along the mobile guide rail. The drive source is, for example, a drive motor.

[0078] When the arc top cutting operation is performed on the edge skin rod using the arc top cutting equipment, the cutting wire driving device drives the first cutting wire to run in the winding direction, and the cutting installation structure driving mechanism drives the first cutting installation structure and its at least one first cutting unit to move in the second direction to achieve relative feeding with the edge skin rod carried by the corresponding at least one first edge skin bearing unit in the first edge skin bearing device so that the arc top of the edge skin rod is cut off by the first cutting wire saw, and an arc top surface is formed on the edge skin rod (the arc top surface may be referred to as the top surface in the following description), and the top surface may be parallel or substantially parallel to the bottom surface.

[0079] In the present application, the arc top cutting device also includes a skin loading and unloading device, which is used to load the skin bar to be cut onto the first skin carrying device and unload the skin bar with the arc top cut off from the first skin carrying device. In addition, in actual application, the skin loading and unloading device may also include unloading the remaining material of the arc top cut off from the first skin carrying device.

[0080] In some embodiments, the edge skin loading and unloading device may include: a reversing carrier and a grabbing unit disposed on the reversing carrier. Figure 1 and Figure 3 In the illustrated embodiment, the arc top cutting device 11 further includes a skin edge handling device 115 , which may include a reversing carrier 1151 and a grabbing unit 1153 disposed on the reversing carrier 1151 .

[0081] The reversing carrier is used to perform reversing motion after being driven, so as to drive the grabbing unit thereon to switch between different working areas. In some embodiments, the working area may include: a feeding area, a loading and unloading area, and a unloading area, wherein the feeding area is used for placing the edge leather rods to be processed, for example, in the feeding area, the edge leather rods are conveyed to the feeding area by a conveyor belt, and the unloading area is used for unloading the edge leather rods with the arc top cut off and the remaining materials of the arc top cut off, and these working areas are set at a certain angle, for example, the feeding area, loading and unloading area, and unloading area are set at 120° to each other, or the feeding area and the loading and unloading area are set at 90°, and the loading and unloading area and the unloading area are set at 90°. In some embodiments, the working area may include: a feeding area, a loading and unloading area, a side leather bar unloading area, and an arc top unloading area. These working areas are arranged at a certain angle. For example, the feeding area, the loading and unloading area, the side leather bar unloading area, and the arc top unloading area are arranged at 90 degrees to each other. For details, see Figure 1 and Figure 3 shown.

[0082] After being driven, the reversing carrier performs reversing motion to switch between various working areas. Figure 1 and Figure 3 In the illustrated embodiment, the feeding area, loading and unloading area, edge skin bar unloading area, and arc top unloading area in the working area are arranged in a clockwise (or counterclockwise) manner at 90° to each other, and the reversing carrier is located at the center of each working area. Assuming that the reversing carrier currently corresponds to the feeding area, the reversing carrier is driven to rotate 90° clockwise, at this time, the reversing carrier corresponds to the loading area. Assuming that the reversing carrier currently corresponds to the loading and unloading area, the reversing carrier is driven to rotate 180° clockwise or counterclockwise, at this time, the reversing carrier corresponds to the arc top unloading area. In some embodiments, the reversing carrier can achieve reversing motion by a carrier rotating mechanism, and the carrier rotating mechanism may include a rotating shaft and a rotating motor.

[0083] The grabbing unit is arranged on the reversing carrier, and is used to grab objects on each work area, wherein the grabbing unit switches between each work area following the reversing movement of the reversing carrier. For example, before the arc top cutting operation is performed, the grabbing unit grabs the edge skin rod to be processed, and after the arc top cutting operation is completed, the grabbing unit grabs the arc top residual material and the edge skin rod with the arc top cut off. In some embodiments, the grabbing unit may be, for example, a vacuum suction cup. In some embodiments, the grabbing unit may be, for example, a clamp.

[0084] As mentioned above, in some embodiments, the first side skin bearing assembly may include a plurality of first side skin bearing units arranged in a vertical layered manner, and correspondingly, the grabbing unit may be movably arranged on the reversing carrier via a lifting mechanism. By means of the lifting mechanism, the grabbing unit may be lifted and moved relative to the reversing carrier so as to be adaptable to each first bearing unit arranged in a layered manner. In some embodiments, the lifting mechanism may include a lifting guide rail and a lifting drive unit, and the lifting guide rail is arranged on the reversing carrier along the lifting direction. In some embodiments, the lifting drive unit may include: a lifting rack, a driving gear, and a driving source, wherein the lifting rack is arranged on the reversing carrier along the lifting direction and is arranged in parallel with the lifting guide rail, the driving gear is meshed with the lifting rack and is associated with the grabbing unit, and the driving source is associated with the driving gear for driving the driving gear to rotate. In some embodiments, the lifting drive unit may include: a lifting screw and a driving source, wherein the lifting screw is arranged along the lifting direction and is associated with the grabbing unit, and the driving source is used to drive the lifting screw to rotate so as to move the lifting guide rail of the associated grabbing unit. In some examples, the driving source may be, for example, a driving motor.

[0085] by Figure 1 and Figure 3Taking the arc top cutting device in the illustrated embodiment as an example, when the arc top cutting operation is performed, the grabbing unit 1153 in the edge skin loading and unloading device 115 grabs the edge skin rod 100 to be processed located in the feeding area. For example, the grabbing unit 1153 can grab two edge skin rods 100 at a time, and drives the reversing carrier 1151 in the edge skin loading and unloading device 115 to rotate (for example, rotate 90° clockwise) from the feeding area to the loading and unloading area, and the grabbing unit 1153 places the grabbed edge skin rod 100 to be processed on the first edge skin bearing platform of the first edge skin bearing component 1111 in the first edge skin bearing device 111 located in the loading area, wherein the first edge skin bearing component 111 of the first edge skin bearing device 111 When 11 includes a plurality of first side skin bearing units arranged in a vertical layered manner, the side skin loading and unloading device 115 needs to perform multiple loading operations of grabbing the side skin rods 100 to be processed from the feeding area and transferring them to the loading and unloading area to place the side skin rods 100 on the first side skin bearing platforms of the corresponding first side skin bearing units. During the loading operation, the grabbing unit 1153 in the side skin loading and unloading device 115 also needs to be lifted and moved relative to the steering carrier 1151 through the lifting mechanism to adapt to the different first side skin bearing units arranged in layers; after the first side skin bearing units (all or according to a set number) in the first side skin bearing assembly 1111 located in the loading and unloading area have completed the loading of the side skin rods 100, the first side skin bearing The conversion mechanism 1112 in the device 111 is converted to drive the first edge skin bearing assembly 1111 located in the loading and unloading area to be converted to the first cutting area and to drive the first edge skin bearing assembly 1111 located in the first cutting area to be converted to the loading and unloading area; the cutting line driving device drives the first cutting line 1134 to run along the winding direction, and the cutting installation structure driving mechanism 1137 drives the first cutting installation structure 1131 and the multiple first cutting units 1132 arranged therein to move along the second direction so that the first cutting line saws 1135 in the multiple first cutting units 1132 and the edge skin bars 100 carried by the corresponding multiple first edge skin bearing units in the first edge skin bearing assembly 1111 located in the first cutting area are mutually connected. For feeding, the arc top of the edge skin bar 100 is cut off by the first cutting wire saw 1135, and accordingly, the edge skin loading and unloading device 115 continues to load the edge skin bar 100 to be processed onto each first edge skin bearing unit in the first edge skin bearing assembly 1111 located in the loading area; after the edge skin bar 100 carried by the multiple first edge skin bearing units in the first edge skin bearing assembly 1111 located in the first cutting area completes the arc top cutting operation, the conversion mechanism 1112 in the first edge skin bearing device 111 is used to convert, drive the first edge skin bearing assembly 1111 located in the first cutting area to convert to the loading and unloading area, and drive the first edge skin bearing assembly 1111 located in the loading and unloading area to convert to the first cutting area;For the first side skin bearing assembly 1111 converted to the loading area, the side skin loading and unloading device 115 sequentially transfers the cut arc top residual material 101 on each first side skin bearing unit in the first side skin bearing assembly 111 to the arc top unloading area, and then the side skin loading and unloading device 115 sequentially transfers the side skin rods 102 with the arc top cut off on each first side skin bearing unit in the first side skin bearing assembly 1111 to the side skin rod unloading area. For the first side skin bearing assembly 1111 converted to the first cutting area, the cutting installation structure driving mechanism 1137 drives the first cutting installation structure 1131 and the multiple first cutting units 1132 provided therein to move along the second direction so that the first cutting wire saws 1135 in the multiple first cutting units 1132 and the side skin rods 100 carried by the corresponding multiple first side skin bearing units in the first side skin bearing assembly 1111 located in the first cutting area are relatively fed, and the arc top of the side skin rod 100 is cut off by the first cutting wire saw 1135. Among them, the operation of sequentially transferring the cut arc top residual material 101 on each first edge skin bearing unit in the first edge skin bearing assembly 1111 to the arc top unloading area by the edge skin loading and unloading device 115 is similar to the operation of sequentially transferring the edge skin rods 102 with the arc top cut off on each first edge skin bearing unit in the first edge skin bearing assembly 1111 to the edge skin rod unloading area by the edge skin loading and unloading device 115. Taking the operation of sequentially transferring the edge skin rods 102 with the arc top cut off on each first edge skin bearing unit in the first edge skin bearing assembly 1111 to the edge skin rod unloading area by the edge skin loading and unloading device 115 as an example, the grabbing unit 1153 in the edge skin loading and unloading device 115 grabs the edge skin rod 102 with the arc top cut off on a first edge skin bearing unit in the loading and unloading area, and drives the reversing carrier 1151 in the edge skin loading and unloading device 115 After rotating (e.g., rotating 90° clockwise) from the loading and unloading area to the edge skin bar unloading area, the grabbing unit 1153 places the grabbed edge skin bar 102 with the arc top cut off in the edge skin bar unloading area (or, for example, a conveyor belt located in the edge skin bar unloading area), wherein, when the first edge skin bearing assembly 1111 of the first edge skin bearing device 111 includes a plurality of first edge skin bearing units arranged in layers vertically, the edge skin loading and unloading device 115 needs to perform multiple unloading operations of grabbing the edge skin bar 102 with the arc top cut off from the loading and unloading area and transferring it to the edge skin bar unloading area to place the edge skin bar 102 in the edge skin bar unloading area, wherein, during the unloading operation, the grabbing unit 1153 in the edge skin loading and unloading device 115 also needs to be lifted and moved relative to the steering carrier 1151 through the lifting mechanism to adapt to different first edge skin bearing units arranged in layers. ;

[0086] The stacking device in the present application is used to stack a plurality of edge skin bars to form an edge skin bar stack, wherein the edge skin bar refers to the edge skin bar with the arc top cut off after the arc top cutting device performs an arc top cutting operation.

[0087] The stacking of the plurality of edge skin bars is specifically achieved by bonding the plurality of edge skin bars together in face-to-face contact. To ensure the firmness of the bonding between the edge skin bars and that the subsequent edge skin bars meet the requirements of the production process, in some implementations, a grinding device is further included between the arc top cutting device and the stacking device, for grinding the edge skin bars with the arc top cut off output by the arc top cutting device. Figure 1 In the illustrated embodiment, a surface grinding device 12 is further provided between the arc top cutting device 11 and the stacking device 13 .

[0088] In some embodiments, the surface grinding operation on the edge skin rod with the arc top cut off includes surface grinding the bottom surface of the edge skin rod with the arc top cut off. In some embodiments, the surface grinding operation on the edge skin rod with the arc top cut off includes surface grinding the bottom surface and top surface of the edge skin rod with the arc top cut off. In some embodiments, the surface grinding operation on the edge skin rod with the arc top cut off includes surface grinding the top surface of the edge skin rod with the arc top cut off. In this embodiment, the arc top cutting operation is performed on the edge skin rod by an arc top cutting device, wherein the first cutting device in the arc top cutting device adopts an annular cutting line, and the annular cutting line can realize high-precision cutting operation, so that the flatness of the top surface of the edge skin rod after the arc top is cut off meets the production process requirements. Therefore, in this embodiment, the surface grinding device is used to grind the bottom surface of the edge skin rod with the arc top cut off output by the arc top cutting device.

[0089] In this application, Figure 1In the illustrated embodiment, a skin edge flipping and conveying device 14 is further included between the arc top cutting device 11 and the surface grinding device 12. The skin edge flipping and conveying device 14 is located in the flipping and conveying area between the arc top cutting device 11 and the surface grinding device 12, and is used to flip the skin edge rod with the arc top cut off and convey it to the surface grinding device 12. In this embodiment, the skin edge rod with the arc top cut off output by the arc top cutting device is placed in the skin edge rod unloading area (or, for example, a conveyor belt located in the skin edge rod unloading area) with the bottom surface at the bottom and the top surface at the top, and the surface grinding device performs surface grinding on the bottom surface of the skin edge rod with the arc top cut off, so it is also necessary to flip the skin edge rod with the arc top cut off to place it with the bottom surface at the top and the top surface at the bottom. Of course, the above is only an exemplary description, but it is not limited to this. For example, in some embodiments, the edge skin loading and unloading device in the arc top cutting equipment can realize the turning operation of the edge skin bar in the process of transferring the edge skin bar with the arc top cut off from the loading and unloading area to the edge skin bar unloading area, so the aforementioned edge skin turning over and the turning over operation of the edge skin bar by the conveying equipment can be eliminated. Or, for example, in some embodiments, the grinding equipment can grind the edge skin bar with the arc top cut off when it is placed in a manner with the bottom surface at the bottom and the top surface at the top, so the aforementioned edge skin turning over and the turning over operation of the edge skin bar by the conveying equipment can be eliminated.

[0090] In some embodiments, the edge skin turning and conveying device may further include an edge skin conveying device and an edge skin turning device. Figure 4 , displayed as Figure 1 Schematic diagram of the structure of the middle edge leather turning and conveying equipment. Figure 1 and Figure 4 In the embodiment shown, the edge skin turning and conveying device 14 includes an edge skin conveying device and an edge skin turning device. The edge skin conveying device is used to transfer the edge skin rods with the arc top cut off from the edge skin rod unloading area to the edge skin turning device, and the edge skin turning device is used to turn over the edge skin rods with the arc top cut off. As mentioned above, in some embodiments, when it is not necessary to turn over the edge skin rods with the arc top cut off, the edge skin turning device can be omitted.

[0091] The edge conveying device may be, for example, a conveyor belt or a conveyor chain.

[0092] The edge skin turning device may include an edge skin turning device, an edge skin rod loading device, and an edge skin rod conveying device.

[0093] The edge skin flipping device is used to flip the edge skin bar whose arc top has been cut off. In some embodiments, the edge skin flipping device includes a flipping mechanism and at least one edge skin clamp provided on the flipping mechanism, and the at least one edge skin clamp is used to clamp the edge skin bar whose arc top has been cut off. In some embodiments, the flipping mechanism may include a rotating shaft and a rotating motor, and the rotating shaft is horizontally arranged.

[0094] The edge skin clamp is arranged on the flipping mechanism, and is used to clamp the edge skin rod with the arc top cut off, wherein the edge skin clamp flips along with the rotation of the flipping mechanism. For example, in the initial state, the edge skin clamp is located at one side of the flipping mechanism and is in a horizontal placement state, and the edge skin rod with the arc top cut off is transported over and placed in the clamping space of the edge skin furniture. At this time, the edge skin rod with the arc top cut off is placed in a manner of bottom surface at the bottom and top surface at the top. Subsequently, the flipping mechanism is driven to rotate (for example, 180° clockwise or counterclockwise) to drive the edge skin furniture from being located at one side of the flipping mechanism and being in a horizontal placement state to being located at the other side of the flipping mechanism and being in a horizontal placement state. At this time, the edge skin rod with the arc top cut off is placed in a manner of bottom surface at the top and top surface at the bottom.

[0095] The edge skin bar loading device is used to load the edge skin bar with the arc top cut off onto the edge skin clamp. In some embodiments, the edge skin bar loading device includes a grasping unit. In some embodiments, the grasping unit may be, for example, a vacuum suction cup. In some embodiments, the grasping unit may be, for example, a clamp. In addition, in some embodiments, in addition to the grasping unit, the edge skin bar loading device also includes a grasping unit moving mechanism for driving the grasping unit to move.

[0096] The edge skin conveying device is used to convey the edge skin rod with the arc top cut off. In some embodiments, edge skin conveying devices are respectively arranged on opposite sides of the edge skin turning device, the edge skin conveying device on one side is used to convey the edge skin rod that has not been turned over (the bottom surface is at the bottom and the top surface is at the top) to the edge skin clamp of the edge skin turning device, and the edge skin conveying device on the other side is used to convey the edge skin rod that has been turned over (the bottom surface is at the top and the top surface is at the bottom) from the edge skin clamp to the grinding device. In some embodiments, the edge skin conveying device can be, for example, a conveyor belt.

[0097] After the edge skin bar with the arc top cut off is turned over by the edge skin turning over and conveying equipment, the bottom surface of the edge skin bar with the arc top cut off can be ground by the grinding equipment.

[0098] In some embodiments, the surface grinding device may include a second edge skin supporting device and a surface grinding device, wherein the second edge skin supporting device is used to support the edge skin rod with the arc top cut off, and the surface grinding device is used to perform surface grinding on the bottom surface of the edge skin rod with the arc top cut off carried by the second edge skin supporting device. In some embodiments, the surface grinding device also includes a grinding machine seat, and the second edge skin supporting device and the surface grinding device are arranged on the grinding machine seat. Figure 5 , displayed as Figure 1 Schematic diagram of the structure of the medium grinding equipment. Figure 1 and Figure 5 In the illustrated embodiment, the surface grinding device 12 may include a grinding machine base 121 and a second edge skin supporting device 123 and a surface grinding device 125 disposed on the grinding machine base 121 .

[0099] In some embodiments, the second side skin supporting device is a mobile side skin supporting device, and the surface grinding device is a fixed surface grinding device. Driving the second side skin supporting device can make the second side skin supporting device move closer to or away from the surface grinding device.

[0100] In some embodiments, the second side skin supporting device is a fixed side skin supporting device, and the surface grinding device is a mobile surface grinding device. The surface grinding device is driven so that the surface grinding device can move closer to or away from the second side skin supporting device.

[0101] In some embodiments, the second side skin supporting device is a mobile side skin supporting device, and the surface grinding device is a mobile surface grinding device. Driving the second side skin supporting device and / or the surface grinding device can make the second side skin supporting device and the surface grinding device move closer to or away from each other.

[0102] The second edge skin supporting device may include a second edge skin supporting platform, and the second edge skin supporting platform may be used to support at least one edge skin rod with the top of the arc cut off. If a edge skin rod with the top of the arc cut off is placed on the second edge skin supporting platform as an example, the length of the second edge skin supporting platform may be related to the length of the edge skin rod with the top of the arc cut off, and the width of the second edge skin supporting platform may be related to the width of the edge skin rod with the top of the arc cut off. If two edge skin rods with the top of the arc cut off are placed on the second edge skin supporting platform in a left-right parallel manner as an example, the length of the second edge skin supporting platform matches the length of the edge skin rod with the top of the arc cut off, and the width of the second edge skin supporting platform matches the sum of the widths of the two edge skin rods with the top of the arc cut off.

[0103] In order to ensure that the edge skin rod with the arc top cut off can be placed firmly on the second edge skin support platform, the second edge skin support device may further include a second edge skin positioning mechanism, which is used to position the edge skin rod carried by the second edge skin support platform.

[0162] The cutting device in the present application is used to cut the edge skin rod stack along the length direction of the edge skin rod to form a plurality of edge skin rod stack segments.

[0163] The cutting device comprises: a third edge skin carrying device and a second cutting device, wherein the third edge skin carrying device is used to carry the edge skin bar stack, and the second cutting device is used to cut the edge skin bar stack carried by the third edge skin carrying device to form a plurality of edge skin bar stack sections. Fig.10 , displayed as Figure 1 The schematic diagram of the structure of the device is shown in Figure 2.

In the present application, the edge skin rod stack to be cut off is cut in a horizontal manner. In some embodiments, the edge skin rod stack to be cut off is placed on the third edge skin supporting device in a horizontal manner, which means that the edge skin rod stack to be cut off is placed on the third edge skin supporting platform in a manner such that the bottom surface is at the bottom and the top surface is at the top, or the bottom surface is at the top and the top surface is at the bottom (that is, the bottom surface or the top surface is used as the supporting surface).

Figure 1 and Fig.10In the embodiment, the third edge skin carrying device 151 may further include a third edge skin positioning mechanism 1513 located on the left and right sides of the third edge skin carrying platform 1511. In this way, when the edge skin rod stack carried by the third edge skin carrying platform is cut by the third cutting device, the edge skin rod stack carried by the third edge skin carrying platform can be positioned by the third edge skin positioning mechanism to avoid relative displacement between the edge skin rod stack and the third edge skin carrying platform during the cutting operation, thereby affecting the cutting quality. In some embodiments, the third edge skin positioning mechanism may be, for example, a edge skin rod stack clamping mechanism for clamping the edge skin rod stack located therebetween. For example, in some examples, the edge skin rod stack clamping mechanism may include a first movable clamp and a second movable clamp arranged opposite to each other along the second direction, and the first movable clamp and the second movable clamp are driven to move toward each other or away from each other by a clamp driving source associated with the first movable clamp and the second movable clamp. In some examples, the edge skin rod stack clamping mechanism may include a backrest and a movable clamp arranged opposite to each other along the second direction, and the movable clamp is driven by a clamp driving source associated with the movable clamp to move toward the backrest or away from the backrest.

[0166] In order to place the edge skin bar stack to be cut on the third edge skin carrying device, in some embodiments, the cutting device further includes: a cutting transfer device, which is used to transfer the edge skin bar stack to the third edge skin carrying device or to move the cut edge skin bar stack segments along the conveying direction.

In some embodiments, the cutting and transporting device may include a roller assembly / roller assembly and a motor assembly for controlling the roller assembly / roller assembly.

Taking the roller assembly as an example, a plurality of rollers are arranged along the first direction, and the axis of the rollers is consistent with the second direction, and the roller surface of each roller can constitute a side leather rod stack bearing surface, and the side leather rod stack bearing surface can be, for example, consistent with the horizontal plane. The motor assembly includes a motor, each of the rollers / rollers corresponds to a motor, or multiple rollers / rollers share one motor, and the motor is used to drive the corresponding rollers / rollers to rotate. The friction between the rollers / rollers and the side leather rod stack or side leather rod stack segment placed thereon can be used to drive the side leather rod stack or side leather rod stack segment to be transported along the first direction.

[0167] In some embodiments, the cut-off transfer device may include a transmission rail and a transmission drive mechanism, the transmission rail is arranged along the first direction, and the transmission drive mechanism includes a transmission chain assembly and an auxiliary roller assembly. The transmission chain assembly may include at least one transmission chain and a driving source. For example, in some embodiments, the transmission chain assembly may include a transmission chain and a driving source, the transmission chain may be a strip-shaped or ring-shaped chain, which is arranged along the first direction and is associated with a transmission member, and the driving source is used to drive the transmission chain to move so that the associated transmission member drives the edge leather rod stack to move along the transmission rail. The driving source is, for example, a driving motor with a sprocket, the sprocket is associated with the transmission chain, and the driving motor can drive the sprocket to rotate forward and reverse. For example, in some embodiments, the transmission chain assembly may include at least two transmission chains and a driving source, wherein the at least two transmission chains may be strip-shaped or ring-shaped chains, wherein one transmission chain is arranged along a first direction and is associated with a transmission member, and the other at least one transmission chain may be associated with the transmission chain arranged along the first direction through a gear sleeve on one hand, and the other at least one transmission chain may be associated with the driving source on the other hand, and the driving source is used to drive the other at least one transmission chain and the associated transmission chain arranged along the first direction to operate so that the transmission member associated with the transmission chain arranged along the first direction drives the edge leather rod stack to move along the transmission guide rail. The driving source is, for example, a driving motor with a sprocket, and the sprocket is associated with the other at least one transmission chain, and the driving motor can drive the other at least one transmission chain to rotate forward and reverse. In some embodiments, the transmission member may be, for example, a transmission block or a transmission splint.

[0168] In some embodiments, in the cutting device, the second cutting device comprises: a second cutting installation structure, at least one second cutting unit, and a cutting unit lifting mechanism. Figure 1 and Fig.10 In the illustrated embodiment, the second cutting device 153 includes: a second cutting installation structure 1531, at least one second cutting unit 1533, and a cutting unit lifting mechanism.

[0169] The second cutting installation structure is arranged on the cutting machine base and corresponds to the second cutting area. Figure 1 and Fig.10 In the illustrated embodiment, the second cutting mounting structure 1531 is disposed on the cutting machine base and corresponds to the second cutting area. In some embodiments, the second cutting mounting structure may be, for example, a mounting bracket, a mounting beam, a mounting column, or the like.

[0170] The second cutting unit includes: a plurality of second cutting wheels and a second cutting wire. Figure 1 and Fig.10In the illustrated embodiment, the second cutting unit 1533 may include: a plurality of second cutting wheels 1532 and a second cutting wire 1534 , wherein the second cutting wire 1534 is wound around the plurality of second cutting wheels 1532 to form at least one second cutting wire saw 1535 .

[0171] The second cutting wheel 1532 is provided with at least one cutting wire groove for winding the second cutting wire 1534. The cutting wire groove can define the position of the second cutting wire to control the cutting accuracy. Any second cutting wire saw 1535 is formed by winding the second cutting wire 1534 between two second cutting wheels 1532. The positions of the two second cutting wheels 1532 and the positional relationship between the second cutting wheels 1532 can be used to determine the direction of the second cutting wire saw 1535.

[0172] In such Figure 1 and Fig.10 In the illustrated embodiment, at least one second cutting wire saw 1535 is located in the second direction, and correspondingly, the wheel surface of at least one second cutting wheel 1532 is parallel to the second direction and the third direction, that is, the wheel surface of at least one second cutting wheel 1532 is located in the vertical plane formed by the second direction and the third direction.

[0173] like Figure 1 and Fig.10 As shown, for example, in some embodiments, the second cutting device 153 includes a plurality of second cutting units 1533, and any second cutting unit 1533 includes a plurality of second cutting wheels 1532, for example, four second cutting wheels 1532, a second cutting wheel 1532a, a second cutting wheel 1532b, a second cutting wheel 1532c, and a second cutting wheel 1532d, the wheel surfaces of the four second cutting wheels 1532 are all located in the vertical plane and form a quadrilateral (for example, a rectangle, a trapezoid, etc.) as a whole, wherein the second cutting wheel 1532a and the second cutting wheel 1532d are 2b is arranged at the bottom and in parallel front and back along the second direction, the second cutting wheel 1532c and the second cutting wheel 1532d are arranged at the top and in parallel front and back along the second direction, the second cutting line 1534 is wound around the second cutting wheel 1532a, the second cutting wheel 1532b, the second cutting wheel 1532c, and the second cutting wheel 1532d to form at least one second cutting wire saw 1535 (for example, the second cutting wire saw 1535 is formed between the second cutting wheel 1532a and the second cutting wheel 1532b), and the at least one second cutting wire saw 1535 is arranged along the second direction.

[0174] In some embodiments, the second cutting line is wound between the second cutting wheels in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line). Figure 1 and Fig.10In the illustrated embodiment, the second cutting line 1534 is wound around four second cutting wheels 1532 in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line).

[0175] The multiple second cutting wheels in the second cutting unit are wound by an annular cutting wire. In this example, the cutting device can omit the wire storage drum. The annular cutting wire is driven by the cutting wire driving device to maintain high-speed operation. At the same time, the annular cutting wire can run in the same direction during the cutting operation (the traditional non-annular cutting wire with a wire storage drum runs alternately in forward and reverse directions). In this way, the cutting device can achieve high-precision cutting operations, avoiding problems such as ripples on the cutting surface caused by the reversal of the cutting wire or the running speed in the existing cutting method; at the same time, the annular cutting wire can effectively reduce the total length of the cutting wire required for the cutting device and reduce production costs.

[0176] In some embodiments, the cutting line driving device is a motor having a power output shaft and the power output shaft is connected to a second cutting wheel, so that the second cutting line can be driven by the wound second cutting wheel to run along the winding direction. Of course, in a specific implementation, the cutting line driving device can also be another driving source such as a hydraulic motor, as long as it can drive the cutting line to run, and this application does not limit it.

[0177] The second cutting unit in the present application may further include a second transition wheel, which is used to change the direction or guide the second cutting line, or the second transition wheel may be used to adjust the tension of the second cutting line. The number of the second transition wheels may be one or more according to layout requirements.

[0178] The second transition wheel, while guiding and pulling the second cutting line, also serves as a tension wheel for adjusting the tension of the second cutting line. The tension wheel is used to adjust the tension of the second cutting line, which can reduce the probability of the second cutting line breaking and reduce consumables.

[0179] like Figure 1 and Fig.10As shown, for example, in some embodiments, in the second cutting device, any one of the second cutting units includes a plurality of second cutting wheels 1532 and a plurality of second transition wheels 1536, for example, a second cutting wheel 1532a, a second cutting wheel 1532b, a second transition wheel 1536a, and a second transition wheel 1536b, the wheel surfaces of the second cutting wheel 1532a, the second cutting wheel 1532b, the second transition wheel 1536a, and the second transition wheel 1536b are all located in the vertical plane and form a quadrilateral (for example, a rectangle, a trapezoid, etc.) as a whole, wherein the second cutting wheel 1532 a and the second cutting wheel 1532b are arranged parallel to each other front and back at the bottom and along the second direction, the second transition wheel 1536a and the second transition wheel 1536b are arranged parallel to each other front and back at the top and along the second direction, the second cutting line 1534 is wound around the second cutting wheel 1532a, the second cutting wheel 1532b, the second transition wheel 1536b, and the second transition wheel 1536a to form at least one second cutting wire saw 1535 (for example, the second cutting wire saw 1535 is formed between the second cutting wheel 1532a and the second cutting wheel 1532b), and the at least one second cutting wire saw 1535 is arranged along the second direction.

[0180] As described above, the second cutting wire is wound around multiple second cutting wheels or multiple second cutting wheels and multiple second transition wheels to form a second cutting wire saw 1535 between the second cutting wheels (for example, between the second cutting wheel 1532a and the second cutting wheel 1532b). Therefore, to adjust the wire length of the second cutting wire saw 1535, it can be achieved by adjusting the spacing between the second cutting wheel 1532a and the second cutting wheel 1532b. The implementation method includes changing the position of at least one of the second cutting wheels 1532a and the second cutting wheel 1532b.

[0181] In addition, the second cutting wire saw can still have other changes. Figure 1 and Fig.10In the illustrated embodiment, the second cutting wheel 1532a and the second cutting wheel 1532b are arranged in parallel along the second direction, and the second cutting line 1534 is wound around multiple second cutting wheels 1532 or multiple second cutting wheels 1532 and multiple second transition wheels 1536 to form a second cutting wire saw 1535 between the second cutting wheels 1532 (for example, between the second cutting wheel 1532a and the second cutting wheel 1532b). The second cutting wire saw 1535 is arranged along the second direction, but is not limited to this. In other embodiments, the position of the second cutting wire saw 1535 may be located in a vertical plane and arranged at a second direction angle to the second direction, and the vertical plane is composed of the second direction and the third direction, and the second direction angle is less than or equal to 45° (≤±45°), that is, the routing direction of the second cutting wire saw 1535 may be located in the same vertical plane as the second direction and form an angle less than or equal to 45° (≤±45°) with the second direction. In this implementation, in the third direction, one of the second cutting wheels 1532a and the second cutting wheel 1532b is at the bottom and the other is at the top, for example, the second cutting wheel 1532a is at the bottom and the second cutting wheel 1532b is at the top (the deflection angle formed by the second cutting wire saw with the second cutting wheel 1532a at the bottom and the second cutting wheel 1532b at the top and the second direction is referred to as a positive deflection angle) or the second cutting wheel 1532b is at the top and the second cutting wheel 1532a is at the bottom (the deflection angle formed by the second cutting wheel 1532a at the top and the second cutting wheel 1532b at the top) The deflection angle formed by the second cutting wire saw 1535 and the second direction is called a negative deflection angle). In this way, when performing truncation cutting, the lower part of the second cutting wire saw 1535 enters the edge skin bar stack 104 first and enters the edge skin bar stack 104 later during the descending process, and continuously cuts the edge skin bar stack 104. Finally, the lower part of the second cutting wire saw 1535 exits the edge skin bar stack 104 first and then the upper part of the second cutting wire saw 1535 exits later, until the edge skin bar stack 104 is truncated to form a plurality of edge skin bar stack segments 105. The deflection angle of the second direction can be changed according to the cutting process requirements and the size specifications of the edge skin bars to be cut. For example, the angle of the deflection angle of the second direction can be adjusted by changing the position of one or both of the second cutting wheel 1532a and the second cutting wheel 1532b associated with the second cutting wire saw 1535.

[0182] In some embodiments, the second cutting unit further includes a tension adjustment mechanism. In the wire cutting process, the tension of the cutting wire affects the yield and processing accuracy of the cutting process, and the tension adjustment mechanism detects the tension and adjusts the tension so that the tension of the cutting wire reaches a certain threshold value set and maintains a constant value during cutting or takes the constant value as a certain range allowed by the center of the value.

[0183] In some embodiments, the tension adjustment mechanism is associated with a transition wheel, and the transition wheel in the wire cutting unit serves as a tension wheel for adjusting the tension of the cutting wire while achieving the guiding and traction of the cutting wire.

[0184] The tension wheel is used to adjust the tension of the cutting wire, which can reduce the probability of the cutting wire breaking and reduce consumables. In the cutting operation, the cutting wire plays a vital role, but even the best cutting wire has limited elongation and wear resistance, which means that the cutting wire will gradually become thinner during continuous operation until it is finally broken. Therefore, wire cutting equipment now generally designs a cutting wire tension compensation mechanism to compensate for the elongation of the cutting wire during its reciprocating movement, and the use of a tension wheel is one means of implementation.

[0185] For example, in some embodiments, the tension adjustment mechanism can perform tension detection and adjust the tension according to the tension detection result. The method of adjusting the tension is not limited, for example, it can be achieved by adjusting the second transition wheel. In some cases, when it is detected that the tension does not reach the set requirement, the position of at least one of the two second transition wheels is adjusted, for example, the second transition wheel is moved outward, the circumference enclosed by each second cutting wheel and each second transition wheel is expanded, and the tension is increased. In some cases, when it is detected that the tension exceeds the set requirement, the position of at least one of the two second transition wheels is adjusted, for example, the second transition wheel is moved inward, the circumference enclosed by each second cutting wheel and each second transition wheel is reduced, and the tension is reduced.

[0186] In some embodiments, the second cutting unit may further include: at least one second distance adjustment mechanism, configured to drive the plurality of second cutting wheels to move relative to the second cutting mounting structure in a direction perpendicular to the cutting wheel surface.

[0187] The second cutting assembly can realize the switching of the second cutting wire between different cutting grooves of the second cutting wheel based on the second distance adjustment mechanism, or adjust the position of the second cutting wire saw (for example, in the first direction) to change the cutting position (or processing specifications) relative to the silicon rod. In practical applications, the second distance adjustment mechanism may, for example, include: a screw, which is arranged along the orthogonal direction of the wheel surface of the second cutting wheel and is threadedly connected to the second cutting wheel; a driving source for driving the screw to rotate. Alternatively, the second distance adjustment mechanism may, for example, include: a telescopic member, which is arranged along the orthogonal direction of the wheel surface of the second cutting wheel and is associated with the second cutting wheel; a driving source for driving the telescopic member to perform telescopic movement along the orthogonal direction of the wheel surface of the second cutting wheel. Alternatively, the second distance adjustment mechanism may, for example, include: a rack, which is arranged on the second cutting wheel along the orthogonal direction of the wheel surface of the second cutting wheel; a transmission gear, which is meshed with the rack; a driving source for driving the transmission gear to rotate.

[0188] The cutting unit lifting mechanism is used to drive the at least one second cutting unit to move vertically relative to the second cutting installation structure.

[0189] In some embodiments, the at least one second cutting unit is movably mounted on the second cutting mounting structure via a second cutting wire rack, that is, the at least one second cutting unit is mounted on the second cutting wire rack, and the second cutting wire rack and the at least one second cutting unit thereon are driven to move vertically relative to the second cutting mounting structure via a cutting unit lifting mechanism.

[0190] In some embodiments, the second cutting units correspond to the second cutting wire racks one by one, that is, each second cutting unit is movably mounted on the second cutting mounting structure through a corresponding second cutting wire rack.

[0191] In some embodiments, the plurality of second cutting units share a second cutting wire rack, that is, the plurality of second cutting units are movably mounted on the second cutting mounting structure through a corresponding second cutting wire rack. Figure 1 and Fig.10 In the illustrated embodiment, two second cutting units 1533 are movably mounted on the second cutting mounting structure 1531 via a corresponding second cutting wire frame 1537. In some embodiments, the second cutting device may include four second cutting units, wherein each two second cutting units may be a group, and the two groups of second cutting units are respectively mounted on opposite sides of the second cutting mounting structure, and the two second cutting units in each group are movably mounted on the second cutting mounting structure via a corresponding second cutting wire frame.

[0192] In some implementations, the cutting unit lifting mechanism may include a lifting rail, a slider, and a lifting drive unit, wherein the lifting rail is arranged on the second cutting installation structure along a third direction, the slider is arranged on the second cutting wire rack and is adapted to the corresponding lifting rail, and the lifting drive unit is used to drive the second cutting wire rack to move up and down along the lifting rail. In actual applications, in order to enable the second cutting wire rack to be stably lifted and lowered on the second cutting installation structure, a double rail design may be adopted, that is, two lifting rails are adopted, and the two lifting rails are arranged in parallel. In addition, the lifting drive unit may further include a lifting screw and a lifting motor, wherein the lifting screw is along the third direction and connected to the second cutting wire rack, and the lifting motor (the lifting motor may be, for example, a servo motor) is connected to the lifting screw. In this way, the lifting motor drives the lifting screw to rotate, so that the second cutting wire rack can be lifted and lowered along the lifting rail. The implementation method of the lifting drive unit is not limited to this. Other components that can drive the second cutting wire rack to move up and down along the lifting guide rail are still applicable. For example, the lifting drive unit may include a lifting rack, a driving gear meshing with the lifting rack, and a driving motor that drives the driving gear to rotate.

The drive source is, for example, a drive motor.

[0200] As mentioned above, in some embodiments, the stack of edge skin bars to be cut off is placed horizontally on the third edge skin supporting device, which means that the stack of edge skin bars to be cut off is placed on the third edge skin supporting device with the bottom surface in front and the top surface in the back, or with the bottom surface in the back and the top surface in the front. In contrast, the stack of edge skin bars undergoing curing in the curing area is placed with the bottom surface at the bottom and the top surface at the top, so when transferring the stack of edge skin bars from the curing area to the third edge skin supporting device, the stack of edge skin bars needs to be turned over.

[0201] In the present application, the cutting device also includes a cutting and folding device, which is used to fold the edge skin rod stack before placing the edge skin rod stack on the third edge skin supporting device. In some embodiments, the cutting and folding device is connected to the third edge skin supporting device, and is used to fold the edge skin rod stack and transfer the folded edge skin rod stack to the third edge skin supporting device. In some embodiments, the cutting and folding device is connected to the cutting and transferring device, and is used to fold the edge skin rod stack before the cutting and transferring device transfers the edge skin rod stack or fold the edge skin rod stack after the cutting and transferring device transfers the edge skin rod stack. In such Figure 1 and Figure 8 In the illustrated embodiment, the cutting equipment further comprises a cutting and folding device 157, which is located between the curing area and the cutting and conveying device 155, and is used for folding the edge skin rod stack 104 before transferring the edge skin rod stack 104 to the cutting and conveying device 155, so that the edge skin rod stack 104 is folded from the original bottom surface at the bottom and the top surface at the top to the bottom surface at the back and the top surface at the front.

[0202] In some embodiments, the folding device includes a folding plate, a rotating shaft, and a rotating mechanism. Figure 1 and Figure 8 In the illustrated embodiment, the folding device includes a folding plate, a rotating shaft, and a rotating mechanism. The folding plate includes a first panel and a second panel, and the angle between the first panel and the second panel is approximately 90°. For example, the first panel corresponds to the bottom surface of the stack of edge leather bars, and the second panel corresponds to one side of the stack of edge leather bars. The spatial rotation angle of the folding plate is also approximately controlled at about 90°. The intersection of the first panel and the second panel in the folding plate is installed on the rotating shaft, and the rotating mechanism is connected to the rotating shaft for transmission. The folding plate rotates forward and reversely on the rotating shaft under the drive of the rotating mechanism. In some embodiments, the rotating mechanism includes a gear assembly and a rotating motor, and the rotating motor drives the gear assembly to rotate to drive the folding plate to rotate around the rotating shaft. In some embodiments, the rotating mechanism may include a support rod and a telescopic cylinder, and the support rod connects the telescopic cylinder and one of the panels (the first panel or the second panel) of the folding plate.

[0203] When applied Figure 8 When the folding device shown folds the edge leather rod stack, first, the edge leather rod stack 104 (with the bottom surface at the bottom and the top surface at the top) that has been cured in the curing area is transferred to the folding device 157. At this time, the first panel of the flipping device 157 corresponds to the bottom surface of the edge leather rod stack 104, and the second panel of the flipping device 157 corresponds to (either against or not against) one side of the edge leather rod stack 104. Afterwards, the rotation source of the flipping device 157 is used to drive the rotating shaft to rotate and drive the folding plate to flip. After flipping approximately 90°, the edge leather rod stack 104 completes a 90° flip, and the edge leather rod stack 104 is placed on the folding device 157 with the side facing downward, forming a shape as shown in the figure. Fig. 9 Status shown.

[0204] When the cutting device equipped with a folding device is used to cut the edge skin bar stack, first, the edge skin bar stack is folded by the flipping device so that the edge skin bar stack is folded from the bottom surface at the bottom and the top surface at the top to the side surface at the bottom; then, the edge skin bar stack located on the folding device is transferred to the cutting and transferring device; then, the edge skin bar stack to be cut is transferred to the third edge skin supporting device by the cutting and transferring device, at this time, the edge skin bar stack is placed on the third edge skin supporting device in a manner of side surface at the bottom (bottom surface at the front and top surface at the back or bottom surface at the back and top surface at the front); then, the placed edge skin bar stack is positioned by the fourth edge skin positioning mechanism so that it is placed firmly; then, the cutting unit lifting mechanism is used to drive the at least one second cutting unit to descend vertically, and the at least one second cutting wire saw in the at least one second cutting unit contacts and cuts the edge skin bar stack until the at least one second cutting wire saw completely passes through the edge skin bar stack to complete the cutting operation, thereby forming a corresponding edge skin bar stack segment.

[0205] In the above embodiments, in the cutting equipment, the second cutting device includes: a second cutting mounting structure, at least one second cutting unit, and a cutting unit lifting mechanism. The cutting unit lifting mechanism is used to drive at least one second cutting unit to move vertically up and down to cut the edge skin rod stack, but this is not limited to this, and the cutting equipment can still be modified in other ways.

[0206] In some embodiments, the second cutting device may include: a second cutting installation structure, at least one second cutting unit, and a cutting unit translation mechanism.

[0207] The second cutting installation structure is arranged on the cutting machine base and corresponds to the second cutting area. In some embodiments, the second cutting installation structure can be, for example, a mounting bracket, a mounting beam, a mounting column, or the like.

[0208] The second cutting unit includes: a plurality of second cutting wheels and a second cutting wire. For example, in some embodiments, the second cutting unit may include: a plurality of second cutting wheels and a second cutting wire, wherein the second cutting wire is wound around the plurality of second cutting wheels to form at least one second cutting wire saw.

[0209] The second cutting wheel is provided with at least one cutting wire groove for winding the second cutting wire, and the cutting wire groove can limit the position of the second cutting wire to control the cutting accuracy. Any second cutting wire saw is formed by winding the second cutting wire between two second cutting wheels, and the positions of the two second cutting wheels and the positional relationship between the second cutting wheels can be used to determine the direction of the second cutting wire saw.

[0210] In some embodiments, at least one second cutting wire saw is located in the third direction, and correspondingly, the wheel surface of at least one second cutting wheel is parallel to the second direction and the third direction, that is, the wheel surface of at least one second cutting wheel is located in the vertical plane formed by the second direction and the third direction.

[0211] For example, in some embodiments, the second cutting device includes multiple second cutting units, and any second cutting unit includes multiple second cutting wheels, such as four second cutting wheels, and the wheel surfaces of the four second cutting wheels are all located in the vertical plane and form a quadrilateral (for example, a rectangle, a trapezoid, etc.) as a whole, wherein two second cutting wheels are in front and arranged in parallel up and down along the third direction, and the other two second cutting wheels are in the back and arranged in parallel up and down along the third direction, and the second cutting wire is wound around the four second cutting wheels to form at least one second cutting wire saw (for example, a second cutting wire saw is formed between the two front second cutting wheels), and the at least one second cutting wire saw is arranged along the third direction.

[0212] In some embodiments, the second cutting line is wound between the second cutting wheels in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line).

[0213] The second cutting unit in the present application may further include a second transition wheel, which is used to change the direction or guide the second cutting line, or the second transition wheel may be used to adjust the tension of the second cutting line. The number of the second transition wheels may be one or more according to layout requirements.

[0214] The second transition wheel, while guiding and pulling the second cutting line, also serves as a tension wheel for adjusting the tension of the second cutting line. The tension wheel is used to adjust the tension of the second cutting line, which can reduce the probability of the second cutting line breaking and reduce consumables.

[0215] For example, in some embodiments, the second cutting device includes multiple second cutting wheels and multiple second transition wheels, for example, two cutting wheels and two transition wheels, the wheel surfaces of the two cutting wheels and the two transition wheels are all located in the vertical plane and form a quadrilateral (for example, a rectangle, a trapezoid, etc.) as a whole, wherein the two second cutting wheels are in front and arranged in parallel up and down along the third direction, the two second transition wheels are in the back and arranged in parallel up and down along the third direction, the second cutting wire is wound around the two cutting wheels and the two transition wheels to form at least one second cutting wire saw (for example, a second cutting wire saw is formed between the two second cutting wheels), and at least one second cutting wire saw is arranged along the third direction.

[0216] As mentioned above, the second cutting wire is wound around multiple second cutting wheels or multiple second cutting wheels and multiple second transition wheels to form a second cutting wire saw between the second cutting wheels. Therefore, to adjust the wire length of the second cutting wire saw, it can be achieved by adjusting the spacing between the two second cutting wheels where the second cutting wire saw is located. The implementation method includes changing the position of at least one of the two second cutting wheels.

[0217] In addition, the second cutting wire saw may still have other changes. For example, in other embodiments, the position of the second cutting wire saw may be located in a vertical plane and arranged at a third direction angle to the third direction, the vertical plane is composed of the second direction and the third direction, and the third direction angle is less than or equal to 45° (≤±45°), that is, the routing direction of the second cutting wire saw may be located in the same vertical plane as the third direction and form an angle less than or equal to 45° (≤±45°) with the third direction. In this implementation, in the third direction, one second cutting wheel is in front and the other second cutting wheel is in the back (the deflection angle formed by the second cutting wire saw formed by the upper second cutting wheel in front and the lower second cutting wheel in the back and the third direction can be called a positive deflection angle, or the deflection angle formed by the second cutting wire saw formed by the upper second cutting wheel in the back and the lower second cutting wheel in the front and the third direction can be called a negative deflection angle), so that when performing truncation cutting, the front part of the second cutting wire saw first enters the edge skin bar stack and the rear part of the second cutting wire saw enters the edge skin bar stack later during the translational advancement process, and the edge skin bar stack is continuously cut, and finally the front part of the second cutting wire saw first exits the edge skin bar stack and then the rear part of the second cutting wire saw exits later, until the edge skin bar stack is truncated. The deflection angle in the third direction can be changed according to the cutting process requirements and the size specifications of the edge skin bar to be cut, for example, the angle of the deflection angle in the third direction can be adjusted by changing the position of one or two second cutting wheels associated with the second cutting wire saw.

[0218] In some embodiments, the second cutting unit further includes a tension adjustment mechanism.

[0219] In some embodiments, the tension adjustment mechanism is associated with a transition wheel, and the transition wheel in the wire cutting unit serves as a tension wheel for adjusting the tension of the cutting wire while achieving the guiding and traction of the cutting wire.

[0220] In some embodiments, the second cutting unit may further include: at least one second distance adjustment mechanism, configured to drive the plurality of second cutting wheels to move relative to the second cutting mounting structure in a direction perpendicular to the cutting wheel surface.

[0221] The cutting unit translation mechanism is used to drive the at least one second cutting unit to translate relative to the third edge skin supporting device.

[0222] In some embodiments, the cutting unit translation mechanism is used to drive at least one second cutting unit to translate relative to the second cutting installation structure, so that the at least one second cutting unit translates relative to the third edge skin supporting device.

[0223] The cutting unit translation mechanism may include: a translation guide rail and a translation drive unit. The translation guide rail is arranged along the second direction and is used to set the at least one second cutting unit. The translation drive unit is used to drive the at least one second cutting unit to move along the translation guide rail.

[0224] In some embodiments, the translation drive unit includes a translation rack, a driving gear, and a driving source. The translation rack is arranged along the second direction and is parallel to the translation guide rail. The driving gear is arranged on at least one second cutting unit or a second cutting wire rack associated with the at least one second cutting unit, and is meshed with the translation rack to drive the at least one second cutting unit to move along the translation guide rail. The driving gear is driven to rotate by the driving source, and the gear teeth of the driving gear are meshed with the translation rack, and follow the movement of the translation rack, so that at least one second cutting unit connected to the driving gear or the second cutting wire rack associated with the at least one second cutting unit produces corresponding movement on the translation guide rail. The driving source is, for example, a driving motor.

[0225] In some embodiments, the translation drive unit includes a translation screw and a drive source, wherein the translation screw is arranged along the second direction and is associated with at least one second cutting unit or a second cutting wire frame associated with the at least one second cutting unit, and the drive source is used to drive the translation screw to rotate so that the associated at least one second cutting unit moves along the translation guide rail. The drive source is, for example, a drive motor.

[0226] When using the cutting equipment to cut the edge skin rod stack, first, use the cutting transfer device to transfer the edge skin rod stack to be cut to the third edge skin carrying device. At this time, the edge skin rod stack is placed on the third edge skin carrying device with the bottom surface at the bottom and the top surface at the top; the cutting wire driving device drives the second cutting wire to run along the winding direction, and the cutting unit translation mechanism drives the at least one second cutting unit to translate along the second direction to achieve relative feeding with the edge skin rod stack carried by the third edge skin carrying device, so that the second cutting wire saw cuts the edge skin rod stack to form a plurality of edge skin rod stack segments.

[0227] Of course, in some embodiments, the third side skin supporting device is of mobile design, that is, the third side skin supporting device may be equipped with a supporting device translation mechanism for driving the third side skin supporting device to translate relative to the second cutting device. Regarding the supporting device translation mechanism, reference may be made to the aforementioned cutting unit translation mechanism, which will not be described in detail here.

[0228] The ear cutting device in the present application is used to perform ear cutting operations on the edge skin rod stack segment along the thickness direction of the edge skin rod to cut off the ears of each edge skin rod in the edge skin rod stack segment.

[0229] The ear cutting equipment includes: a fourth side skin carrying device and a third cutting device, wherein the fourth side skin carrying device is used to carry the side skin rod stack segment, and the third cutting device is used to perform ear cutting operations on the side skin rod stack segment carried by the fourth side skin carrying device to cut off the ears of each side skin rod in the side skin rod stack segment.

[0230] The fourth side skin supporting device is used to support the side skin bar stack segment. In some embodiments, the fourth side skin supporting device includes a fourth side skin supporting platform. In this application, refer to Fig.10 , displayed as Figure 1 Schematic diagram of the structure of the middle ear cutting device. Figure 1 and Fig.10 In the illustrated embodiment, the ear cutting device 17 may include a fourth side skin supporting device 171 and a third cutting device 173. In order to facilitate the cutting of the ears on opposite sides of the side skin bar stack segment, the side skin bar stack segment to be cut is placed on the fourth side skin supporting platform 1711 with the cut surface as the supporting surface. In addition, the ear cutting device includes two fourth side skin supporting devices 171, which are spaced apart along the first direction, and each of the fourth side skin supporting devices 171 can carry at least one side skin bar stack segment 105.

[0231] In order to place the edge skin bar stack segment stably on the fourth edge skin support platform, the fourth edge skin support device may further include a fourth edge skin positioning mechanism for positioning the edge skin bar stack segment carried by the fourth edge skin support platform. Figure 1 and Fig.10 In the embodiment of the present invention, the fourth side skin supporting device 171 may further include a fourth side skin positioning mechanism 1713 located at the front and rear ends of the fourth side skin supporting platform 1711 along the second direction. In this way, when the third cutting device is used to perform ear cutting operation on the side skin rod stack segment carried by the fourth side skin supporting platform, the fourth side skin positioning mechanism can be used to position the side skin rod stack segment carried by the fourth side skin supporting platform, so as to avoid relative displacement between the side skin rod stack segment and the fourth side skin supporting platform or relative displacement between the cut ear and the side skin rod stack segment during the ear cutting operation, thereby affecting the cutting quality. In some embodiments, the fourth side skin positioning mechanism may be, for example, a side skin clamping mechanism. For a side skin rod stack segment, the side skin clamping mechanism may include two clamping jaws or clamping blocks arranged along the thickness direction of the side skin rod stack segment and a driving source for driving the clamping jaws or clamping blocks. When in use, the placed side skin rod stack segment is located in the placement space between the two clamping jaws or clamping blocks, and the driving source is used to drive the two clamping jaws or clamping blocks to move toward or actuate along the thickness direction of the side skin rod stack segment, thereby clamping the side skin rod stack segment located therebetween. Alternatively, the fourth side skin positioning mechanism may include a backrest and a movable jaw or a movable clamping block, and a driving source for driving the movable jaw or the movable clamping block, wherein the backrest is located on one side, and the movable jaw or the movable clamping block is located on the other side along the thickness direction of the side skin rod stack segment. When in use, the placed side skin rod stack segments are respectively located in the placement space formed by the backrest and the movable jaw or the movable clamping block, and the driving source is used to drive the movable jaw or the movable clamping block to move along the thickness direction of the side skin rod stack segment toward the backrest to clamp the side skin rod stack segment located therebetween.

[0232] In addition, in some embodiments, the fourth side skin supporting device may include an ear supporting mechanism, which is disposed on opposite sides of the fourth side skin supporting platform and is used to support the ears of the side skin bar stack segment being carried. Figure 1 and Fig.10In the illustrated embodiment, ear supporting mechanisms 1715 are provided on opposite sides of the fourth side skin support platform 1711. In certain embodiments, the ear supporting mechanism 1715 may include a supporting member and an adjusting member associated with the supporting member, the supporting member may be, for example, a supporting plate or a supporting frame or a supporting block, the supporting member may be rotatably connected to the fourth side skin support platform, and the adjusting member may be, for example, a cylinder or an oil cylinder or an elastic telescopic member. In practical application, when cutting the ear, the adjusting member drives the supporting member to be in a supporting state, and is used to support the ear of the side skin rod stack segment at the corresponding position until the ear cutting is completed, and the cut ear is supported by the supporting member, and then the adjusting member drives the supporting member to rotate to change from the supporting state to the unloading state, and the supported ear can be unloaded.

[0233] In order to place the edge skin bar stack to be cut on the fourth edge skin carrying device, in some embodiments, the ear cutting device further includes: a cutting and transporting device, which is used to flip the edge skin bar stack segment and transport it to the fourth edge skin carrying device. In some embodiments, the cutting and transporting device can be, for example, a transport clamp or a suction cup transport manipulator. Figure 1 and Fig.10 In the embodiment of the ear cutting device 17, the ear cutting device 17 also includes a cutting and transporting device 175. The cutting and transporting device 175 takes a suction cup transporting robot as an example. The suction cup transporting robot can be flexibly changed and can be lifted up and down, translated left and right, moved forward and backward, and rotated, etc. It can suck the cut side skin rod stack segment 105 from the third side skin supporting device 151 of the cutting device 15 and transfer it to the fourth side skin supporting device 171 of the ear cutting device 17, wherein the side skin rod stack segment placed on the fourth side skin supporting device 171 is flipped 90° compared to when it is placed on the third side skin supporting device, so that the cut surface of the placed side skin rod stack segment 105 is at the bottom, the bottom surface is at the back and the top surface is at the front (or the bottom surface is at the front and the top surface is at the back) and the two ears are located on opposite sides along the first direction.

[0234] In some embodiments, in the ear cutting device, the third cutting device includes: a third cutting installation structure, at least one third cutting unit, and a cutting unit lifting mechanism. Figure 1 and Fig.10 In the illustrated embodiment, the third cutting device 173 includes: a third cutting installation structure 1731, at least one third cutting unit 1733, and a cutting unit lifting mechanism.

[0235] The third cutting installation structure is arranged on the cutting machine base and corresponds to the third cutting area. Figure 1 and Fig.10In the illustrated embodiment, the third cutting mounting structure 1731 is disposed on the cutting machine base and corresponds to the third cutting area. In some embodiments, the third cutting mounting structure may be, for example, a mounting bracket, a mounting beam, a mounting column, or the like.

[0236] The at least one third cutting unit is arranged on the third cutting installation structure, and the third cutting unit comprises: a plurality of third cutting wheels and a third cutting line. Figure 1 and Fig.10 In the illustrated embodiment, third cutting units 1733 are disposed on both left and right sides of the third cutting installation structure 1731, wherein each side is provided with two third cutting units 1733. The third cutting unit 1733 may include: a plurality of third cutting wheels 1732 and a third cutting line 1734, wherein the third cutting line 1734 is wound around the plurality of third cutting wheels 1732 to form at least one third cutting line saw 1735.

[0237] The third cutting wheel 1732 is provided with at least one cutting wire groove for winding the third cutting wire 1734. The cutting wire groove can limit the position of the third cutting wire to control the cutting accuracy. Any third cutting wire saw 1735 is formed by winding the third cutting wire 1734 between two third cutting wheels 1732. The positions of the two third cutting wheels 1732 and the positional relationship between the third cutting wheels 1732 can be used to determine the direction of the third cutting wire saw 1735.

[0238] In such Figure 1 and Fig.10 In the illustrated embodiment, at least one third cutting wire saw 1735 is located in the second direction, and correspondingly, the wheel surface of at least one third cutting wheel 1732 is parallel to the second direction and the third direction, that is, the wheel surface of at least one third cutting wheel 1732 is located in the vertical plane formed by the second direction and the third direction.

[0239] like Figure 1 and Fig.10As shown, for example, in some embodiments, the third cutting device 173 includes a plurality of third cutting units, and any third cutting unit 1733 includes a plurality of third cutting wheels 1732, for example, four third cutting wheels 1732, a third cutting wheel 1732a, a third cutting wheel 1732b, a third cutting wheel 1732c, and a third cutting wheel 1732d, the wheel surfaces of the four third cutting wheels 1732 are all located in the vertical plane and form a quadrilateral (for example, a rectangle, a trapezoid, etc.) as a whole, wherein the third cutting wheel 1732a and the third cutting wheel 1732b The third cutting wheels 1732c and 1732d are arranged in parallel at the bottom and front and back along the second direction, and the third cutting wheel 1732a, the third cutting wheel 1732b, the third cutting wheel 1732c, and the third cutting wheel 1732d are arranged in parallel at the top and front and back along the second direction. The third cutting wire 1734 is wound around the third cutting wheel 1732a, the third cutting wheel 1732b, the third cutting wheel 1732c, and the third cutting wheel 1732d to form at least one third cutting wire saw 1735 (for example, the third cutting wire saw 1735 is formed between the third cutting wheel 1732a and the third cutting wheel 1732b), and the at least one third cutting wire saw 1735 is arranged along the second direction.

[0240] In some embodiments, the third cutting line is wound between the third cutting wheels in an end-to-end manner to form a ring-shaped cutting line (also referred to as a closed-loop cutting line). Figure 1 and Fig.10 In the illustrated embodiment, the third cutting line 1734 is wound around four third cutting wheels 1732 in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line).

[0241] The multiple third cutting wheels in the third cutting unit are wound by a circular cutting wire. In this example, the ear cutting device can omit the wire storage drum. The circular cutting wire is driven by the cutting wire driving device to maintain high-speed operation. At the same time, the circular cutting wire can run in the same direction during the cutting operation (the traditional non-circular cutting wire with a wire storage drum runs alternately in forward and reverse directions). In this way, the ear cutting device can achieve high-precision cutting operations, avoiding problems such as ripples on the cutting surface caused by the reversal of the cutting wire or the running speed in the existing cutting method; at the same time, the circular cutting wire can effectively reduce the total length of the cutting wire required for the ear cutting device and reduce production costs.

[0242] In some embodiments, the cutting line driving device is a motor having a power output shaft and the power output shaft is connected to a third cutting wheel, so that the third cutting line can be driven by the wound third cutting wheel to run along the winding direction. Of course, in a specific implementation, the cutting line driving device can also be another driving source such as a hydraulic motor, as long as it can drive the cutting line to run, and this application does not limit it.

[0243] The third cutting unit in the present application may further include a third transition wheel, which is used to change the direction or guide the third cutting line, or the third transition wheel can be used to adjust the tension of the third cutting line. The number of the third transition wheels can be one or more according to the layout requirements.

[0244] The third transition wheel, while guiding and pulling the third cutting line, also serves as a tension wheel for adjusting the tension of the third cutting line. The tension wheel is used to adjust the tension of the third cutting line, which can reduce the probability of the third cutting line breaking and reduce consumables.

[0245] like Figure 1 and Fig.10 As shown, for example, in some embodiments, in the third cutting device, any third cutting unit includes a plurality of third cutting wheels 1732 and a plurality of third transition wheels 1736, for example, a third cutting wheel 1732a, a third cutting wheel 1732b, a third transition wheel 1736a, and a third transition wheel 1736b, the wheel surfaces of the third cutting wheel 1732a, the third cutting wheel 1732b, the third transition wheel 1736a, and the third transition wheel 1736b are all located in the vertical plane and form a quadrilateral (for example, a rectangle, a trapezoid, etc.) as a whole, wherein the third cutting wheel 1732a The third cutting wheel 1732a and the third transition wheel 1736b are arranged in parallel front and back at the bottom and along the second direction, the third transition wheel 1736a and the third transition wheel 1736b are arranged in parallel front and back at the top and along the second direction, the third cutting line 1734 is wound around the third cutting wheel 1732a, the third cutting wheel 1732b, the third transition wheel 1736b, and the third transition wheel 1736a to form at least one third cutting wire saw 1735 (for example, the third cutting wire saw 1735 is formed between the third cutting wheel 1732a and the third cutting wheel 1732b), and at least one third cutting wire saw 1735 is set along the second direction.

[0246] As described above, the third cutting wire is wound around multiple third cutting wheels or multiple third cutting wheels and multiple third transition wheels to form a third cutting wire saw 1735 between the third cutting wheels (for example, between the third cutting wheel 1732a and the third cutting wheel 1732b). Therefore, to adjust the wire length of the third cutting wire saw 1735, it can be achieved by adjusting the spacing between the third cutting wheel 1732a and the third cutting wheel 1732b. The implementation method includes changing the position of at least one of the third cutting wheels 1732a and the third cutting wheel 1732b.

[0247] In addition, the third cutting wire saw can still have other changes, such as Figure 1In the illustrated embodiment, the third cutting wheel 1732a and the third cutting wheel 1732b are arranged in parallel along the second direction, and the third cutting line 1734 is wound around multiple third cutting wheels 1732 or multiple third cutting wheels 1732 and multiple third transition wheels 1736 to form a third cutting wire saw 1735 between the third cutting wheels 1732 (for example, between the third cutting wheel 1732a and the third cutting wheel 1732b). The third cutting wire saw 1735 is arranged along the second direction, but is not limited to this. In other embodiments, the position of the third cutting wire saw 1735 may be located in a vertical plane and arranged at a second direction angle to the second direction, and the vertical plane is composed of the second direction and the third direction, and the second direction angle is less than or equal to 45° (≤±45°), that is, the routing direction of the third cutting wire saw 1735 may be located in the same vertical plane as the second direction and form an angle less than or equal to 45° (≤±45°) with the second direction. In this implementation, in the third direction, one of the third cutting wheels 1732a and 1732b is at the bottom and the other is at the top. For example, the third cutting wheel 1732a is at the bottom and the third cutting wheel 1732b is at the top (the deflection angle formed by the third cutting line saw formed by the third cutting wheel 1732a at the bottom and the third cutting wheel 1732b at the top and the second direction is referred to as a positive deflection angle) or the third cutting wheel 1732b is at the top and the third cutting wheel 1732a is at the bottom (the third cutting line saw formed by the third cutting wheel 1732a at the top and the third cutting wheel 1732b at the top is referred to as a positive deflection angle). The deflection angle formed by the saw and the second direction is called a negative deflection angle). In this way, when cutting the ear, the lower part of the third cutting wire saw 1735 first enters the edge skin bar stack segment 105 and enters the edge skin bar stack segment 105 later during the descending process, and continuously cuts the edge skin bar stack segment 105. Finally, the lower part of the third cutting wire saw 1735 first exits the edge skin bar stack segment 105 and then the upper part of the third cutting wire saw 1735 exits later, until the ear 107 in the edge skin bar stack segment 105 is cut off to form the edge skin sheet stack 106. The second direction deflection angle can be changed according to the cutting process requirements and the size specifications of the edge skin bar to be cut. For example, the angle of the second direction deflection angle can be adjusted by changing the position of one or both of the third cutting wheel 1732a and the third cutting wheel 1732b related to the third cutting wire saw 1735.

[0248] In some embodiments, the third cutting unit further includes a tension adjustment mechanism. In the wire cutting process, the tension of the cutting wire affects the yield and processing accuracy of the cutting process, and the tension adjustment mechanism detects the tension and adjusts the tension so that the tension of the cutting wire reaches a certain threshold value set and maintains a constant value during cutting or takes the constant value as a certain range allowed by the center of the value.

[0249] In some embodiments, the tension adjustment mechanism is associated with a transition wheel, and the transition wheel in the wire cutting unit serves as a tension wheel for adjusting the tension of the cutting wire while achieving the guiding and traction of the cutting wire.

[0250] The tension wheel is used to adjust the tension of the cutting wire, which can reduce the probability of the cutting wire breaking and reduce consumables. In the cutting operation, the cutting wire plays an important role, but even the best cutting wire has limited elongation and wear resistance, which means that the cutting wire will gradually become thinner during continuous operation until it is finally broken. Therefore, current wire cutting equipment generally has a cutting wire tension compensation mechanism to compensate for the elongation of the cutting wire during its reciprocating movement, and the use of a tension wheel is one means of implementation.

[0251] like Figure 1 and Fig.10 As shown, for example, in some embodiments, the tension adjustment mechanism can perform tension detection and adjust the tension according to the tension detection result. The method of adjusting the tension is not limited, for example, it can be achieved by adjusting the third transition wheel 1736. In some cases, when it is detected that the tension does not reach the set requirement, the position of at least one of the two third transition wheels 1736 is adjusted, for example, the third transition wheel 1736 is moved outward to expand the circumference surrounded by each third cutting wheel 1732 and each third transition wheel 1736, thereby increasing the tension. In some cases, when it is detected that the tension exceeds the set requirement, the position of at least one of the two third transition wheels 1736 is adjusted, for example, the third transition wheel 1736 is moved inward to reduce the circumference surrounded by each third cutting wheel 1732 and each third transition wheel 1736, thereby reducing the tension.

[0252] In some embodiments, the third cutting unit may further include: at least one third distance adjustment mechanism, configured to drive the plurality of third cutting wheels to move relative to the third cutting mounting structure in a direction perpendicular to the cutting wheel surface.

[0253] The third cutting assembly can realize the switching of the third cutting wire between different cutting grooves of the third cutting wheel based on the third distance adjustment mechanism, or adjust the position of the third cutting wire saw (for example, in the first direction) to change the cutting position (or processing specifications) relative to the silicon rod. In practical applications, the third distance adjustment mechanism may, for example, include: a screw, which is arranged along the orthogonal direction of the wheel surface of the third cutting wheel and is threadedly connected to the third cutting wheel; a driving source for driving the screw to rotate. Alternatively, the third distance adjustment mechanism may, for example, include: a telescopic member, which is arranged along the orthogonal direction of the wheel surface of the third cutting wheel and is associated with the third cutting wheel; a driving source for driving the telescopic member to perform telescopic movement along the orthogonal direction of the wheel surface of the third cutting wheel. Alternatively, the third distance adjustment mechanism may, for example, include: a rack, which is arranged on the third cutting wheel along the orthogonal direction of the wheel surface of the third cutting wheel; a transmission gear, which is meshed with the rack; and a driving source for driving the transmission gear to rotate.

[0254] The cutting unit lifting mechanism is used to drive the at least one third cutting unit to move vertically relative to the third cutting installation structure.

[0255] In some embodiments, the at least one third cutting unit is movably mounted on the third cutting mounting structure via a third cutting wire rack, that is, the at least one third cutting unit is mounted on the third cutting wire rack, and the third cutting wire rack and the at least one third cutting unit thereon are driven to move vertically relative to the third cutting mounting structure via a cutting unit lifting mechanism.

[0256] In some embodiments, the third cutting units correspond to the third cutting wire racks one by one, that is, each third cutting unit is movably mounted on the third cutting mounting structure through a corresponding third cutting wire rack.

[0257] In some embodiments, a plurality of third cutting units share a third cutting wire rack, that is, a plurality of third cutting units are movably mounted on the third cutting mounting structure through a corresponding third cutting wire rack. Figure 1 and Fig.10 In the illustrated embodiment, third cutting units are provided on both sides of the left and right sides of the third cutting installation structure 1731, wherein two third cutting units 1733 are provided on each side, and the two third cutting units 1733 located on the same side are movably arranged on the third cutting installation structure 1731 through a corresponding third cutting wire frame, and are used to perform ear cutting operations on the side skin rod stack segment 105 carried by the fourth side skin carrying device 171 in the third cutting area.

[0258] In some implementations, the cutting unit lifting mechanism may include a lifting rail, a slider, and a lifting drive unit, wherein the lifting rail is arranged on the third cutting installation structure along a third direction, the slider is arranged on the third cutting wire rack and is adapted to the corresponding lifting rail, and the lifting drive unit is used to drive the third cutting wire rack to move up and down along the lifting rail. In actual applications, in order to enable the third cutting wire rack to be stably lifted and lowered on the third cutting installation structure, a double rail design may be adopted, that is, two lifting rails are adopted, and the two lifting rails are arranged in parallel. In addition, the lifting drive unit may further include a lifting screw and a lifting motor, wherein the lifting screw is along the third direction and connected to the third cutting wire rack, and the lifting motor (the lifting motor may be, for example, a servo motor) is connected to the lifting screw. In this way, the lifting motor drives the lifting screw to rotate, so that the third cutting wire rack can be lifted and lowered along the lifting rail. The implementation method of the lifting drive unit is not limited to this. Other components that can drive the third cutting wire rack to move up and down along the lifting guide rail are still applicable. For example, the lifting drive unit may include a lifting rack, a driving gear meshing with the lifting rack, and a driving motor that drives the driving gear to rotate.

[0259] In such Figure 1 and Fig.10In the illustrated embodiment, the third cutting device 173 includes four third cutting units 1733, and the third cutting units 1733 are arranged on both the left and right sides of the third cutting installation structure 1731, wherein two third cutting units 1733 are arranged on each side, and the two third cutting units 1733 located on the same side form a third cutting unit assembly, and the two third cutting units 1733 in the same third cutting unit assembly are movably arranged on the third cutting installation structure 1731 through a corresponding third cutting wire frame. The two third cutting units 1733 in each third cutting unit assembly can form two parallel third cutting wire saws 1735, which are used to correspondingly cut the two opposite ears in the edge skin bar stack segment 105 carried on the fourth edge skin carrying device 171. Of course, in certain other embodiments, for example, the third cutting device includes four third cutting units, and the four third cutting units are combined in groups of two to form two third cutting unit assemblies, and each third cutting unit assembly is arranged on a third cutting wire rack, that is, the first third cutting unit assembly is arranged on the first third cutting wire rack, and the second third cutting unit assembly is arranged on the second third cutting wire rack, wherein the first third cutting wire rack can be lifted and moved vertically relative to the third cutting mounting structure by the first cutting unit lifting mechanism, and the second third cutting wire rack can be lifted and moved vertically relative to the third cutting mounting structure by the second cutting unit lifting mechanism, and the two third cutting units in each third cutting unit assembly can form two parallel third cutting wire saws, which are used to correspondingly cut the two opposite ears in the edge skin rod stack carried on the fourth edge skin carrying device.

[0260] The ear cutting device also includes a side skin stack segment unloading device, which is used to unload the side skin bar stack segments of the cut ears. In some embodiments, the side skin stack segment unloading device can be, for example, a handling fixture or a suction cup handling manipulator. Among them, the side skin stack segment unloading device can be an independent device or shared with the cutting and handling device. In some implementations, the side skin stack segment unloading device can be shared with the aforementioned cutting and handling device.

[0261] The ear cutting device also includes an ear unloading device for unloading the ear. Figure 1 and Fig.10 In the illustrated embodiment, the ear unloading device 176 may be, for example, an ear conveyor belt. For example, an ear conveyor belt may be provided on opposite sides of the fourth side skin supporting device 171 .

[0262] As mentioned above, in some embodiments, the edge skin bar stack segment to be cut is placed on the fourth edge skin supporting device in a manner such that the cut surface is at the bottom, the bottom surface is at the back and the top surface is at the front (or the bottom surface is at the front and the top surface is at the back), and the two ears are located on opposite sides along the first direction. Therefore, when using the ear cutting equipment in the edge skin assembly line system of the present application to perform ear cutting operations, first, use a cutting and transporting device to transfer the edge skin bar stack segment located at the cutting device to the fourth edge skin supporting device of the ear cutting equipment, and the fourth edge skin supporting platform in the fourth edge skin supporting device and the ear supporting mechanisms on both sides carry the edge skin bar stack segment; then, use the fourth edge skin positioning mechanism to position the placed edge skin bar stack segment so that it is firmly placed; then, use the cutting unit lifting mechanism to drive the at least one third cutting unit The element descends vertically, and at least one third cutting wire saw in the at least one third cutting unit contacts and cuts the edge leather rod stack segment, until the at least one third cutting wire saw completely passes through the edge leather rod stack segment to complete the ear cutting operation, and the ears of each edge leather rod in the edge leather rod stack segment are cut off; then, the cut ears are transferred to the ear unloading device (such as an ear conveyor belt) by using the ear supporting mechanism, the ears are unloaded by the ear unloading device, and the edge leather rod stack segment unloading device is used to unload the edge leather rod stack segment with the ears cut off.

[0263] Subsequently, the edge leather rod stack segment (also referred to as edge leather sheet stack or edge leather block) with the ear removed can be subjected to subsequent processing such as grinding and chamfering.

[0264] In the above embodiments, in the ear cutting equipment, the third cutting device includes: a third cutting installation structure, at least one third cutting unit, and a cutting unit lifting mechanism, and the cutting unit lifting mechanism is used to drive at least one third cutting unit to move vertically up and down to perform ear cutting operations on the edge skin rod stack segment, but it is not limited to this, and the ear cutting equipment can still be changed in other ways. For example, in some embodiments, the third cutting device may include: a third cutting installation structure, at least one third cutting unit, and a cutting unit translation mechanism, and the cutting unit translation mechanism is used to drive at least one third cutting unit to translate to perform ear cutting operations on the edge skin rod stack segment. Alternatively, in some embodiments, the fourth edge skin bearing device is of mobile design, that is, the fourth edge skin bearing device may be configured with a bearing device translation mechanism for driving the fourth edge skin bearing device to translate relative to the third cutting device.

[0265] The edge skin assembly line system disclosed in the present application includes an arc top cutting device, a stacking device, a cutting device, and an ear cutting device. The arc top cutting device is used to cut the edge skin rod to cut off the arc top of the edge skin rod. The stacking device is used to stack multiple edge skin rods with the arc tops cut off to form an edge skin rod stack. The cutting device is used to cut the edge skin rod stack to form multiple edge skin rod stack segments. The ear cutting device is used to perform ear cutting on the edge skin rod stack segments to cut off the ears of each edge skin rod in the edge skin rod stack segment. In this way, the edge skin rod with an arched cross-section can be cut into a rectangular cross-section after processing. Through assembly line operation, the processing efficiency and reuse of the edge skin rods are improved, saving resources and costs.

[0266] The second aspect of the present application further proposes a system for the production of edge skins. Fig.11 and Fig.12 ,in, Fig.11 It is a schematic diagram of the structure of another embodiment of the edge skin assembly line system of the present application. Fig.12 Display as Fig.11 Schematic diagram of the status of each process involved in the middle edge skin assembly line operation system performing related operations on the edge skin sticks.

[0267] like Fig.11 As shown, a silicon rod cutting and grinding machine disclosed in an embodiment of the present application includes an arc top cutting device 21, an ear cutting device 23, a stacking device 25, and a cutting device 27 which are arranged in sequence according to the production process.

[0268] The arc top cutting device is used to perform arc top cutting operation on the edge skin bar to cut off the arc top of the edge skin bar. Fig.13 , displayed as Fig.11 Schematic diagram of the structure of the middle arc top cutting equipment. Fig.11 and Fig.13 In the illustrated embodiment, the arc top cutting device 21 is used to perform an arc top cutting operation on the edge skin rod along the width direction of the edge skin rod to cut off the arc top of the edge skin rod. After removing the arc top of the edge skin rod, the edge skin rod with the arc top cut off forms a top surface with a smaller width and a bottom surface with a larger width, and ears with curved surfaces on both sides between the top surface and the bottom surface.

[0269] In some embodiments, the arc top cutting device includes: a first edge skin supporting device and a first cutting device, wherein the first edge skin supporting device is used to support an edge skin rod, and the first cutting device is used to perform an arc top cutting operation on the edge skin rod supported by the first edge skin supporting device to cut off the arc top of the edge skin rod. The cross section of the edge skin rod here is arched, including a rectangular bottom surface and a lower arc surface opposite to the bottom surface. Fig.11 and Fig.13In the illustrated embodiment, the arc top cutting device 21 comprises: a first edge skin carrying device 211 and a first cutting device 213 .

[0270] Generally, the implementation method of using the first cutting device to perform an arc top cutting operation on the edge skin rod carried by the first edge skin bearing device to cut off the arc top of the edge skin rod includes using the first cutting device and the first edge skin bearing device to produce relative movement to perform the arc top cutting operation. In some embodiments, the first edge skin bearing device is a fixed edge skin bearing device and the first cutting device is a mobile cutting device. When performing the arc top cutting operation, the first cutting device is driven to move, that is, the first cutting device moves relative to the first edge skin bearing device and the edge skin rod carried by it. In some embodiments, the first edge skin bearing device is a mobile edge skin bearing device and the first cutting device is a mobile cutting device. When performing the arc top cutting operation, the first cutting device is driven to move and the first edge skin bearing device is driven to move respectively, that is, the first cutting device and the first edge skin bearing device and the edge skin rod carried by it move toward each other. In some embodiments, the first edge skin supporting device is a mobile edge skin supporting device and the first cutting device is a fixed cutting device. When performing arc top cutting operation, the first edge skin supporting device is driven to move, that is, the first edge skin supporting device and the edge skin rod it carries move relative to the first cutting device.

[0271] In some embodiments, the first edge skin supporting device includes at least one first edge skin supporting component. In some implementations, the first edge skin supporting component may be fixed, that is, the first edge skin supporting component in the first edge skin supporting device is fixedly arranged in the first cutting area. In some implementations, the first edge skin supporting component is movable, for example, the first edge skin supporting component in the first edge skin supporting device is provided with a rotating pivot, and the rotating pivot can drive the associated first edge skin supporting component to switch between the first cutting area and other working areas, and the other working areas may include one or more, for example, the other working areas may include a loading area, an unloading area, or a loading and unloading area, etc., and for another example, the other working areas may include a loading area and an unloading area, etc.

[0272] In some embodiments, the first side skin bearing device includes at least two first side skin bearing assemblies, and the at least two first side skin bearing assemblies are converted between different working areas through a conversion mechanism. For example, in some embodiments, the first side skin bearing device includes two first side skin bearing assemblies, and the two first side skin bearing assemblies can be arranged at a certain angle. For example, the working area may include a loading area and a first cutting area, and the loading area and the first cutting area are arranged relative to each other, and the two first side skin bearing assemblies can be arranged at 180°. A conversion mechanism is set between the two first side skin bearing assemblies, so that when one first side skin bearing assembly is located in the loading area, the other first side skin bearing assembly is located in the first cutting area, and the conversion mechanism is converted by ±180°, so that the two first side skin bearing assemblies can be driven to convert between the loading area and the first cutting area. For another example, the working area may include a loading area and a first cutting area, the loading area and the first cutting area are arranged at 90°, the two first side skin bearing assemblies may be arranged at 90°, and a conversion mechanism is arranged between the two first side skin bearing assemblies, so that when one first side skin bearing assembly is located in the loading area, the other first side skin bearing assembly is located in the first cutting area, and the two first side skin bearing assemblies can be driven to switch between the loading area and the first cutting area by converting ±90° through the conversion mechanism. The loading area is only an exemplary description, for example, in other embodiments, the loading area may also be, for example, a loading and unloading area, an unloading area or other working area. The setting angle of the loading area and the first cutting area may also be changed differently, and the angle may also be, for example, 100°, 110°, 120°, 130°, 140°, 150° or other angles, which are not limited here. In addition, the working area is not limited to one, and may also include two, three, or more. For example, the working area may include a loading area, a first cutting area, and an unloading area, and the three working areas are arranged at an angle (e.g., 90°, 120°, etc.), so that the first side skin bearing assembly is driven to switch between the various working areas by switching ±90° or ±120° through a conversion mechanism. In some implementations, the conversion mechanism may be, for example, a rotating pivot driven by a motor.

[0273] In such Fig.11 and Fig.13 In the illustrated embodiment, the working area includes a loading and unloading area and a first cutting area which are arranged opposite to each other (arranged at 180°), and the first side skin supporting device 211 includes two first side skin supporting components 2111 which are arranged opposite to each other (arranged at 180°), and the two first side skin supporting components 2111 are converted between the loading and unloading area and the first cutting area via a conversion mechanism 2112.

[0274] Regarding the first side skin bearing assembly, the first side skin bearing assembly may include one or more first side skin bearing units, each of which may be used to bear at least one side skin rod. For example, in some embodiments, the first side skin bearing assembly may include a plurality of first side skin bearing units arranged in a vertical layered manner, wherein each first side skin bearing unit may be used to bear at least one side skin rod. For example, the side skin bearing assembly may include three, four, five, or six first side skin bearing units arranged in a vertical layered manner, and each first side skin bearing unit may bear one, two, or more side skin rods. For example, each first side skin bearing unit may bear two side skin rods, and the two carried side skin rods are placed on the first side skin bearing unit in a left-right parallel manner.

[0275] In such Fig.11 and Fig.13 In the illustrated embodiment, the first side skin bearing assembly 2111 includes a plurality of (for example, three, four, five, or six, etc.) first side skin bearing units arranged in layers vertically (i.e., the third direction), and each first side skin bearing unit carries two side skin rods 200, which are arranged in parallel on the left and right sides.

[0276] The first edge skin bearing unit may include a first edge skin bearing platform, the length of the first edge skin bearing platform may be related to the length of the edge skin rod, and the width of the first edge skin bearing platform may be related to the width of the edge skin rod. Still taking the example of two edge skin rods being placed on the first edge skin bearing platform in a left-right parallel manner, the length of the first edge skin bearing platform matches the length of the edge skin rod, and the width of the first edge skin bearing platform matches the sum of the widths of the two edge skin rods.

[0277] In order to place the edge skin bar firmly on the first edge skin supporting platform, the first edge skin supporting unit may further include a first edge skin positioning mechanism for positioning the edge skin bar carried by the first edge skin supporting platform. In this way, when the first cutting device is used to perform arc top cutting on the edge skin bar carried by the first edge skin supporting platform, the first edge skin positioning mechanism can be used to position the edge skin bar carried by the first edge skin supporting platform, so as to avoid relative displacement between the edge skin bar and the first edge skin supporting platform or relative displacement between the cut arc top and the edge skin bar during the arc top cutting operation, thereby affecting the cutting quality. In some embodiments, the first side skin positioning mechanism may be, for example, a side skin clamping mechanism. For a side skin rod, the side skin clamping mechanism may include two clamping jaws or clamping blocks arranged along the width direction of the side skin rod and a driving source for driving the clamping jaws or clamping blocks. When in use, the placed side skin rod is located in the placement space between the two clamping jaws or clamping blocks. The driving source is used to drive the two clamping jaws or clamping blocks to move toward or actuate along the width direction of the side skin rod to clamp the side skin rod located therebetween. Alternatively, for two edge skin bars arranged in parallel left and right, the first edge skin positioning mechanism may include a backrest, two clamping claws or clamping blocks, and a driving source for driving the clamping claws or clamping blocks, wherein the backrest is centrally arranged, and the two clamping claws or clamping blocks are arranged on opposite sides of the backrest along the width direction of the edge skin bar. When in use, the two placed edge skin bars are respectively located in two placement spaces formed by the backrest and the two clamping claws or clamping blocks on both sides, and the two clamping claws or clamping blocks are driven by the driving source to move toward or actuate along the width direction of the edge skin bar to cooperate with the central backrest to clamp the two edge skin bars located therebetween. In some embodiments, the first edge skin positioning mechanism may be, for example, an edge skin clamping mechanism. For one edge skin bar, the edge skin clamping mechanism may include a top clamping block and a driving source for driving the top clamping block. When in use, the edge skin bar is placed on the first edge skin supporting platform, and the driving source is used to drive the top clamping block to descend along a third direction to clamp the edge skin bar located thereunder.

[0278] In some embodiments, the first edge skin supporting platform may be provided with a suction cup for adsorbing the bottom surface of the edge skin rod after the edge skin rod is placed.

[0279] The first cutting device is used to perform an arc top cutting operation on the edge skin rod carried by the first edge skin carrying device to cut off the arc top of the edge skin rod.

[0280] In some embodiments, the first cutting device includes a first cutting mounting structure and a first cutting unit, wherein the first cutting unit is disposed on the first cutting mounting structure and corresponds to the first side skin bearing unit in the first side skin bearing assembly of the first side skin bearing device, so as to perform arc top cutting operation on the side skin rod carried by the first side skin bearing unit.

[0281] Generally, for the first cutting device, a cutting machine base is also included, which is used to set the first cutting installation structure and the first cutting unit. The cutting machine base serves as the main component of the first cutting device. In some examples, the cutting machine base is large in size and weight to provide a large mounting surface and a firm stability of the whole machine. It should be understood that the cutting machine base can be used as a base for different structures or components that perform processing operations in the first cutting device, and the specific structure of the cutting machine base can be changed based on different functional requirements or structural requirements. In some examples, the cutting machine base includes a fixed structure or a limiting structure such as a base, a rod body, a column, a frame, etc. for receiving different components in the silicon rod cutting and grinding machine, which are all the cutting machine bases described in this application. At the same time, in some examples, the cutting machine base can be an integrated base, and in some examples, the cutting machine base can include multiple independent bases.

[0282] The first cutting installation structure is arranged on the cutting machine base and corresponds to the first cutting area. Fig.11 and Fig.13 In the illustrated embodiment, the first cutting mounting structure 2131 is disposed on the cutting machine base and corresponds to the first cutting area. In some embodiments, the first cutting mounting structure may be, for example, a mounting bracket, a mounting beam, a mounting column, or the like.

[0283] As mentioned earlier, in Fig.11 and Fig.13 In an embodiment, the first side skin bearing assembly 2111 includes a plurality of first side skin bearing units arranged in vertical layers, each first side skin bearing unit can carry at least one side skin rod 200, and accordingly, the first cutting device includes a plurality of first cutting units 2132 arranged in vertical layers and corresponding to the plurality of first side skin bearing units in the first side skin bearing assembly 2111.

[0284] The first cutting unit includes a plurality of first cutting wheels and a first cutting wire. Fig.11 and Fig.13 In the illustrated embodiment, the first cutting unit 2132 includes: a plurality of first cutting wheels 2133 and a first cutting wire 2134 . The first cutting wire 2134 is wound around the plurality of first cutting wheels 2133 to form at least one first cutting wire saw 2135 .

[0285] The first cutting wheel 2133 is provided with at least one cutting wire groove for winding the first cutting wire 2134. The cutting wire groove can define the position of the first cutting wire to control the cutting accuracy. Any first cutting wire saw 2135 is formed by winding the first cutting wire 2134 between two first cutting wheels 2133. The positions of the two first cutting wheels 2133 and the positional relationship between the first cutting wheels 2133 can be used to determine the direction of the first cutting wire saw 2135.

[0286] In such Fig.11 and Fig.13 In the illustrated embodiment, at least one first cutting wire saw 2135 is located in the first direction, and correspondingly, the wheel surface of at least one first cutting wheel 2133 is parallel to the first direction and the second direction, that is, the wheel surface of at least one first cutting wheel 2133 is located in a horizontal plane formed by the first direction and the second direction.

[0287] like Fig.11 and Fig.13 As shown, for example, in some embodiments, the first cutting assembly includes a plurality of first cutting units, and any first cutting unit 2132 includes a plurality of first cutting wheels 2133, for example, four first cutting wheels 2133, a first cutting wheel 2133a, a first cutting wheel 2133b, a first cutting wheel 2133c, and a first cutting wheel 2133d, the wheel surfaces of the four first cutting wheels 2133 are all located in a horizontal plane and form a quadrilateral (for example, a rectangle, a trapezoid, etc.) as a whole, wherein the first cutting wheel 2133a and the first cutting wheel 2133b are in the front (relatively closer to the loading and unloading area). The first cutting wheel 2133c and the first cutting wheel 2133d are arranged in parallel along the first direction at the rear (relatively farther away from the loading and unloading area) and in parallel along the first direction. The first cutting wire 2134 is wound around the first cutting wheel 2133a, the first cutting wheel 2133b, the first cutting wheel 2133c, and the first cutting wheel 2133d to form at least one first cutting wire saw 2135 (for example, the first cutting wire saw 2135 is formed between the first cutting wheel 2133a and the first cutting wheel 2133b), and the at least one first cutting wire saw 2135 is arranged along the first direction. In addition, in order to enable the at least one first cutting wire saw 2135 to effectively cut the edge skin bar 200 to be cut, the at least one first cutting wire saw 2135 must interfere with the edge skin bar 200 to be cut in the third direction, that is, the at least one first cutting wire saw 2135 corresponds to the arc top of the edge skin bar 200 to be cut in the third direction.

[0288] In some embodiments, the first cutting line is wound between the first cutting wheels in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line). Fig.11 and Fig.13 In the illustrated embodiment, the first cutting line 2134 is wound around four first cutting wheels 2133 in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line).

[0289] The multiple first cutting wheels in the first cutting unit are wound by an annular cutting wire. In this example, the arc top cutting device can omit the wire storage drum. The annular cutting wire is driven by the cutting wire driving device to maintain high-speed operation. At the same time, the annular cutting wire can run in the same direction during the cutting operation (the traditional non-annular cutting wire with a wire storage drum runs alternately in forward and reverse directions). In this way, the arc top cutting device can achieve high-precision cutting operations, avoiding problems such as ripples on the cutting surface caused by the reversal of the cutting wire or the running speed in the existing cutting method; at the same time, the annular cutting wire can effectively reduce the total length of the cutting wire required for the arc top cutting device, thereby reducing production costs.

[0290] In some embodiments, the cutting line driving device is a motor having a power output shaft and the power output shaft is connected to a first cutting wheel, so that the first cutting line can be driven by the wound first cutting wheel to run along the winding direction. Of course, in a specific implementation, the cutting line driving device can also be another driving source such as a hydraulic motor, as long as it can drive the cutting line to run, and this application does not limit it.

[0291] The first cutting assembly in the present application may further include a first transition wheel, which is used to change the direction or guide the first cutting line, or the first transition wheel may be used to adjust the tension of the first cutting line. The number of the first transition wheels may be one or more according to layout requirements.

[0292] The first transition wheel, while guiding and pulling the first cutting line, also serves as a tension wheel for adjusting the tension of the first cutting line. The tension wheel is used to adjust the tension of the first cutting line, which can reduce the probability of the first cutting line breaking and reduce consumables.

[0293] like Fig.11 and Fig.13As shown, for example, in some embodiments, the first cutting assembly includes a plurality of first cutting wheels and a plurality of first transition wheels, for example, a first cutting wheel 2133a, a first cutting wheel 2133b, a first transition wheel 2136a, and a first transition wheel 2136b, the wheel surfaces of the first cutting wheel 2133a, the first cutting wheel 2133b, the first transition wheel 2136a, and the first transition wheel 2136b are all located in a horizontal plane and form a quadrilateral (for example, a rectangle, a trapezoid, etc.) as a whole, wherein the first cutting wheel 2133a and the first cutting wheel 2133b are in the front (relatively closer to the front). The first transition wheel 2136a and the first transition wheel 2136b are arranged in parallel along the first direction at the rear (relatively farther from the loading and unloading area) and in parallel along the first direction. The first cutting wire 2134 is wound around the first cutting wheel 2133a, the first cutting wheel 2133b, the first transition wheel 2136b, and the first transition wheel 2136a to form at least one first cutting wire saw 2135 (for example, the first cutting wire saw 2135 is formed between the first cutting wheel 2133a and the first cutting wheel 2133b), and the at least one first cutting wire saw 2135 is arranged along the first direction. In addition, in order to enable the at least one first cutting wire saw 2135 to effectively cut the edge skin bar 200 to be cut, the at least one first cutting wire saw 2135 must interfere with the edge skin bar 200 to be cut in the third direction, that is, the at least one first cutting wire saw 2135 corresponds to the arc top of the edge skin bar 200 to be cut in the third direction.

[0294] As described above, the first cutting wire is wound around multiple first cutting wheels or multiple first cutting wheels and multiple first transition wheels to form a first cutting wire saw 2135 between the first cutting wheels (for example, between the first cutting wheel 2133a and the first cutting wheel 2133b). Therefore, to adjust the wire length of the first cutting wire saw 2135, it can be achieved by adjusting the spacing between the first cutting wheel 2133a and the first cutting wheel 2133b. The implementation method includes changing the position of at least one of the first cutting wheels 2133a and the first cutting wheel 2133b.

[0295] In addition, the first cutting wire saw can still have other changes. Fig.11 and Fig.13In the illustrated embodiment, the first cutting wheel 2133a and the first cutting wheel 2133b are arranged in parallel along the first direction, and the first cutting line 2134 is wound around multiple first cutting wheels 2133 or multiple first cutting wheels 2133 and multiple first transition wheels 2136 to form a first cutting wire saw 2135 between the first cutting wheels 2133 (for example, between the first cutting wheel 2133a and the first cutting wheel 2133b). The first cutting wire saw 2135 is arranged along the first direction, but is not limited to this. In other embodiments, the position of the first cutting wire saw 2135 may be located in a horizontal plane and arranged at a first direction angle to the first direction, and the horizontal plane is composed of the first direction and the second direction, and the first direction angle is less than or equal to 45° (≤±45°), that is, the routing direction of the first cutting wire saw 2135 may be located in the same horizontal plane as the first direction and form an angle less than or equal to 45° (≤±45°) with the first direction. In this implementation, in the second direction, one of the first cutting wheel 2133a and the first cutting wheel 2133b is in front and the other is in the back, for example, the first cutting wheel 2133a is in front and the first cutting wheel 2133b is in the back (the deflection angle formed by the first cutting wire saw with the first cutting wheel 2133a in front and the first cutting wheel 2133b in the back and the first direction is called a positive deflection angle) or the first cutting wheel 2133b is in front and the first cutting wheel 2133a is in the back (the first cutting wheel 2133a is in the back and the first cutting wheel 2133b is in the back) The deflection angle formed by the first cutting wire saw formed by the cutting wheel 2133b in front and the first direction is called a negative deflection angle). In this way, when cutting the top of the arc, the front part of the first cutting wire saw 2135 enters the edge skin bar 200 first and the rear part of the first cutting wire saw 2135 enters the edge skin bar 200 later during the advancement process, and continuously cuts the edge skin bar 200. Finally, the front part of the first cutting wire saw 2135 exits the edge skin bar 200 first and then the rear part of the first cutting wire saw 2135 exits later, until the top of the arc of the edge skin bar 200 is cut off. The deflection angle of the first direction can be changed according to the cutting process requirements and the size specifications of the edge skin bar to be cut. For example, the angle of the deflection angle of the first direction can be adjusted by changing the position of one or both of the first cutting wheel 2133a and the first cutting wheel 2133b related to the first cutting wire saw 2135.

[0296] In some embodiments, the first cutting assembly further includes a tension adjustment mechanism. In the wire cutting process, the cutting wire tension affects the yield and processing accuracy of the cutting process, and the tension adjustment mechanism detects the tension and adjusts the tension so that the cutting wire tension reaches a certain threshold value and maintains a constant value during cutting or takes the constant value as a certain range allowed by the center of the value.

[0297] In some embodiments, the tension adjustment mechanism is associated with a transition wheel, and the transition wheel in the wire cutting unit serves as a tension wheel for adjusting the tension of the cutting wire while achieving the guiding and traction of the cutting wire.

[0298] The tension wheel is used to adjust the tension of the cutting wire, which can reduce the probability of the cutting wire breaking and reduce consumables. In the cutting operation, the cutting wire plays a vital role, but even the best cutting wire has limited elongation and wear resistance, which means that the cutting wire will gradually become thinner during continuous operation until it is finally broken. Therefore, wire cutting equipment generally has a cutting wire tension compensation mechanism to compensate for the elongation of the cutting wire during its reciprocating movement, and the use of a tension wheel is one means of implementation.

[0299] For example, in some embodiments, the tension adjustment mechanism can perform tension detection and adjust the tension according to the tension detection result. The method of adjusting the tension is not limited, for example, it can be achieved by adjusting the first transition wheel. In some cases, when it is detected that the tension does not reach the set requirement, the position of at least one of the two first transition wheels is adjusted, for example, the first transition wheel is moved outward, the circumference enclosed by each first cutting wheel and each first transition wheel is expanded, and the tension is increased. In some cases, when it is detected that the tension exceeds the set requirement, the position of at least one of the two first transition wheels is adjusted, for example, the first transition wheel is moved inward, the circumference enclosed by each first cutting wheel and each first transition wheel is reduced, and the tension is reduced.

[0300] In some embodiments, the first cutting assembly may further include: at least one first distance adjustment mechanism, for driving the plurality of first cutting wheels to move relative to the first cutting mounting structure in a direction perpendicular to the cutting wheel surface.

[0301] The first cutting assembly can realize the switching of the first cutting wire between different cutting grooves of the first cutting wheel based on the first distance adjustment mechanism, or adjust the position of the first cutting wire saw (for example, in the third direction) to change the cutting position (or processing specifications) relative to the silicon rod. In practical applications, the first distance adjustment mechanism may, for example, include: a screw, which is arranged along the orthogonal direction of the wheel surface of the first cutting wheel and is threadedly connected to the first cutting wheel; a driving source for driving the screw to rotate. Alternatively, the first distance adjustment mechanism may, for example, include: a telescopic member, which is arranged along the orthogonal direction of the wheel surface of the first cutting wheel and is associated with the first cutting wheel; a driving source for driving the telescopic member to perform telescopic movement along the orthogonal direction of the wheel surface of the first cutting wheel. Alternatively, the first distance adjustment mechanism may, for example, include: a rack, which is arranged on the first cutting wheel along the orthogonal direction of the wheel surface of the first cutting wheel; a transmission gear, which is meshed with the rack; and a driving source for driving the transmission gear to rotate.

[0302] In some implementations, the first cutting device is a mobile cutting device, and therefore, the first cutting device further comprises: a cutting installation structure driving mechanism, which is used to drive the first cutting installation structure and the plurality of first cutting units provided therein to move relative to the first edge skin bearing device. Fig.11 and Fig.13 In the illustrated embodiment, the first cutting device 213 further includes a cutting installation structure driving mechanism 2137 for driving the first cutting installation structure 2131 and the plurality of first cutting units 2132 thereof to move along the second direction.

[0303] In some embodiments, the cutting installation structure driving mechanism includes: a movable guide rail and a movable driving unit. The movable guide rail is arranged along the second direction and is used to set the first cutting installation structure. The movable driving unit is used to drive the first cutting installation structure and at least one first cutting unit provided therein to move along the movable guide rail.

[0304] In some embodiments, the mobile drive unit includes a mobile rack, a driving gear, and a driving source. The mobile rack is arranged along the second direction and is parallel to the mobile guide rail. The driving gear is arranged on the first cutting mounting structure and meshes with the mobile rack to drive the first cutting mounting structure to move along the mobile guide rail. The driving gear is driven to rotate by the driving source, and the gear teeth of the driving gear mesh with the mobile rack and move in accordance with the movement of the mobile rack, thereby causing the first cutting mounting structure connected to the driving gear to move accordingly on the mobile guide rail. The driving source is, for example, a driving motor.

[0305] In some embodiments, the mobile drive unit may be arranged on the first cutting installation structure, and includes a mobile screw and a drive source, wherein the mobile screw is arranged along the second direction and is associated with the first cutting installation structure, and the drive source is used to drive the mobile screw to rotate so that the associated first cutting installation structure and at least one first cutting unit arranged therein move along the mobile guide rail. The drive source is, for example, a drive motor.

[0306] When the arc top cutting operation is performed on the edge skin rod using the arc top cutting equipment, the cutting wire driving device drives the first cutting wire to run in the winding direction, and the cutting installation structure driving mechanism drives the first cutting installation structure and its at least one first cutting unit to move in the second direction to achieve relative feeding with the edge skin rod carried by the corresponding at least one first edge skin bearing unit in the first edge skin bearing device so that the arc top of the edge skin rod is cut off by the first cutting wire saw, and an arc top surface is formed on the edge skin rod (the arc top surface may be referred to as the top surface in the following description), and the top surface may be parallel or substantially parallel to the bottom surface.

[0307] In the present application, the arc top cutting device also includes a side skin loading and unloading device, which is used to load the side skin rod to be cut onto the first side skin supporting device and unload the side skin rod with the arc top cut off from the first side skin supporting device. In addition, in actual application, the side skin loading and unloading device may also include unloading the remaining material of the arc top cut off from the first side skin supporting device.

In some embodiments, the working area may include: a feeding area, a loading and unloading area, and a unloading area, wherein the feeding area is used for placing the edge leather rods to be processed, for example, in the feeding area, the edge leather rods are conveyed to the feeding area by a conveyor belt, and the unloading area is used for unloading the edge leather rods with the arc top cut off and the remaining materials of the arc top cut off, and these working areas are set at a certain angle, for example, the feeding area, loading and unloading area, and unloading area are set at 120° to each other, or the feeding area and the loading and unloading area are set at 90°, and the loading and unloading area and the unloading area are set at 90°. In some embodiments, the working area may include: a feeding area, a loading and unloading area, a side leather bar unloading area, and an arc top unloading area. These working areas are arranged at a certain angle. For example, the feeding area, the loading and unloading area, the side leather bar unloading area, and the arc top unloading area are arranged at 90 degrees to each other. For details, see Fig.11 and Fig.13 shown.

[0310] After being driven, the reversing carrier performs reversing motion to switch between various working areas. Fig.11 and Fig.13 In the illustrated embodiment, the feeding area, loading and unloading area, edge skin bar unloading area, and arc top unloading area in the working area are arranged in a clockwise (or counterclockwise) manner at 90° to each other, and the reversing carrier is located at the center of each working area. Assuming that the reversing carrier currently corresponds to the feeding area, the reversing carrier is driven to rotate 90° clockwise, at this time, the reversing carrier corresponds to the loading area. Assuming that the reversing carrier currently corresponds to the loading and unloading area, the reversing carrier is driven to rotate 180° clockwise or counterclockwise, at this time, the reversing carrier corresponds to the arc top unloading area. In some embodiments, the reversing carrier can achieve reversing motion by a carrier rotating mechanism, and the carrier rotating mechanism may include a rotating shaft and a rotating motor.

[0311] The grabbing unit is arranged on the reversing carrier, and is used to grab objects on each work area, wherein the grabbing unit switches between each work area following the reversing movement of the reversing carrier. For example, before the arc top cutting operation is performed, the grabbing unit grabs the edge skin rod to be processed, and after the arc top cutting operation is completed, the grabbing unit grabs the arc top residual material and the edge skin rod with the arc top cut off. In some embodiments, the grabbing unit may be, for example, a vacuum suction cup. In some embodiments, the grabbing unit may be, for example, a clamp.

[0312] As mentioned above, in some embodiments, the first side skin bearing assembly may include a plurality of first side skin bearing units arranged in a vertical layered manner, and correspondingly, the grabbing unit may be movably arranged on the reversing carrier via a lifting mechanism.

For example, the grabbing unit 2153 can grab two edge skin rods 200 at a time, and drives the reversing carrier 2151 in the edge skin loading and unloading device 215 to rotate (for example, rotate 90° clockwise) from the feeding area to the loading and unloading area, and the grabbing unit 2153 places the grabbed edge skin rod 200 to be processed on the first edge skin bearing platform of the first edge skin bearing component 2111 in the first edge skin bearing device 211 located in the loading area, wherein the first edge skin bearing component 2111 of the first edge skin bearing device 211 When it includes multiple first side skin bearing units arranged in vertical layers, the side skin loading and unloading device 215 needs to perform multiple loading operations of grabbing the side skin rods 200 to be processed from the feeding area and transferring them to the loading and unloading area to place the side skin rods 200 on the first side skin bearing platforms of the corresponding first side skin bearing units. During the loading operation, the grabbing unit 2153 in the side skin loading and unloading device 215 also needs to be lifted and moved relative to the steering carrier 2151 through the lifting mechanism to adapt to the different first side skin bearing units arranged in layers; after the first side skin bearing units (all or according to the set number) in the first side skin bearing assembly 2111 located in the loading and unloading area have completed the loading of the side skin rods 200, the first side skin bearing device is used to The conversion mechanism 2112 in 211 is converted to drive the first edge skin bearing assembly 2111 located in the loading and unloading area to be converted to the first cutting area and to drive the first edge skin bearing assembly 2111 located in the first cutting area to be converted to the loading and unloading area; the first cutting line 2134 is driven by the cutting line driving device to run along the winding direction, and the first cutting installation structure 2131 and the multiple first cutting units 2132 provided therein are driven by the cutting installation structure driving mechanism 2137 to move along the second direction so that the first cutting line saw 2135 in the multiple first cutting units 2132 and the edge skin rods 200 carried by the corresponding multiple first edge skin bearing units in the first edge skin bearing assembly 2111 located in the first cutting area are relative to each other. Feeding, the arc top of the edge skin bar 200 is cut off by the first cutting wire saw 2135, and accordingly, the edge skin loading and unloading device 215 continues to load the edge skin bar 200 to be processed onto each first edge skin bearing unit in the first edge skin bearing assembly 2111 located in the loading area; after the edge skin bar 200 carried by the multiple first edge skin bearing units in the first edge skin bearing assembly 2111 located in the first cutting area completes the arc top cutting operation, the conversion mechanism 2112 in the first edge skin bearing device 211 is used to convert, drive the first edge skin bearing assembly 2111 located in the first cutting area to convert to the loading and unloading area, and drive the first edge skin bearing assembly 2111 located in the loading and unloading area to convert to the first cutting area;For the first side skin bearing assembly 2111 transferred to the loading area, the side skin loading and unloading device 215 sequentially transfers the arc top residual material 201 cut off from each first side skin bearing unit in the first side skin bearing assembly 2111 to the arc top unloading area, and then the side skin loading and unloading device 215 sequentially transfers the arc top cut off from each first side skin bearing unit in the first side skin bearing assembly 2111 to the side skin bar unloading area. The supporting component 2111, the cutting installation structure driving mechanism 2137 drives the first cutting installation structure 2131 and the multiple first cutting units 2132 provided therein to move along the second direction so that the first cutting wire saw 2135 in the multiple first cutting units 2132 and the edge skin rods 200 carried by the corresponding multiple first edge skin supporting units in the first edge skin supporting component 2111 located in the first cutting area are relatively fed, and the arc top of the edge skin rod 200 is cut off by the first cutting wire saw 2135. Among them, the operation of sequentially transferring the cut arc top residual material 201 on each first side skin bearing unit in the first side skin bearing assembly 2111 to the arc top unloading area by the side skin loading and unloading device 215 is similar to the operation of sequentially transferring the arc top cut edge side skin rods 202 on each first side skin bearing unit in the first side skin bearing assembly 2111 to the arc top unloading area by the side skin loading and unloading device 215. Taking the sequential transfer of the arc top cut edge side skin rods 202 on each first side skin bearing unit in the first side skin bearing assembly 2111 to the arc top unloading area by the side skin loading and unloading device 215 as an example, the grabbing unit 2153 in the side skin loading and unloading device 215 grabs the arc top cut edge side skin rod 202 on a first side skin bearing unit in the loading and unloading area, and drives the reversing carrier 2151 in the side skin loading and unloading device 215 to After rotating (e.g., rotating 90° clockwise) from the loading and unloading area to the edge skin bar unloading area, the grabbing unit 2153 places the grabbed edge skin bar 202 with the arc top cut off in the edge skin bar unloading area (or, for example, a conveyor belt located in the edge skin bar unloading area), wherein, when the first edge skin bearing assembly 2111 of the first edge skin bearing device 211 includes a plurality of first edge skin bearing units arranged in layers vertically, the edge skin loading and unloading device 215 needs to perform multiple unloading operations of grabbing the edge skin bar 202 with the arc top cut off from the loading and unloading area and transferring it to the edge skin bar unloading area to place the edge skin bar 202 in the edge skin bar unloading area, wherein, during the unloading operation, the grabbing unit 2153 in the edge skin loading and unloading device 215 needs to be lifted and moved relative to the steering carrier 2151 through the lifting mechanism to adapt to different first edge skin bearing units arranged in layers. ;

[0314] The ear cutting device in the present application is used to perform ear cutting operations on the edge leather rod with the arc top cut off along the thickness direction of the edge leather rod to cut off the two ears of the edge leather rod with the arc top cut off to form an edge leather strip with a rectangular cross-section.

[0315] In the present application, a skin edge conveying device is further included between the arc top cutting device and the ear cutting device. The skin edge conveying device is located in the conveying area between the arc top cutting device and the ear cutting device and is used to convey the skin edge rod with the arc top cut off to the ear cutting device.

Fig.11 and Fig.14 In the illustrated embodiment, the ear cutting device 23 may include a second edge skin supporting device and a second cutting device 233. To facilitate the cutting of the ears on opposite sides of the edge skin bar with the arc top cut off, the edge skin bar with the arc top cut off is placed on the second edge skin supporting platform 2311 of the second edge skin supporting device with the bottom surface on top and the top surface on the bottom.

When in use, the two side skin rods 202 with the arc tops cut off are respectively located in the two placement spaces formed by the backrest 23131 and the movable jaws or movable clamping blocks 23133. The driving source is used to drive the movable jaws or movable clamping blocks 23133 on both sides to move along the width direction of the side skin rods 202 with the arc tops cut off toward the backrest 23131, so as to clamp the two side skin rods 202 with the arc tops cut off therebetween.

For an edge skin rod with a cut arc top, the edge skin end clamping mechanism may include two clamping jaws or clamping blocks arranged along the length direction of the edge skin rod with a cut arc top and a driving source for driving the clamping jaws or clamping blocks. When in use, the edge skin rod with a cut arc top is placed in the placement space between the two clamping jaws or clamping blocks. The driving source is used to drive the two clamping jaws or clamping blocks to move or actuate toward each other along the length direction of the edge skin rod with a cut arc top, thereby clamping the edge skin rod with a cut arc top located therebetween. Fig.11 Fig.14 In the illustrated embodiment, the second side skin positioning mechanism may include two movable jaws or movable blocks 23135 (or, a backrest and a movable jaw or movable block) located at the front and rear ends of the second side skin supporting platform 2311 along the first direction, and a driving source for driving the movable jaws or movable block 23135. When in use, the side skin rod 202 at the top of the cut arc placed on the second side skin supporting platform 2311 is respectively located in two placement spaces formed by the two movable jaws or movable blocks 23135 (or, a backrest and a movable jaw or movable block).

[0322] The at least one second cutting unit is disposed on the second cutting mounting structure, and the second cutting unit includes: a plurality of second cutting wheels and a second cutting line. Fig.11 and Fig.14 In the illustrated embodiment, the second cutting mounting structure 2331 may be provided with four second cutting units 2333, and the four second cutting units 2333 may be combined in groups of two to form two second cutting unit assemblies, and the two second cutting unit assemblies may be arranged on the same second cutting wire rack, and the second cutting wire rack and the four second cutting units 2333 thereon may be lifted and lowered vertically relative to the second cutting mounting structure 2331 by a cutting unit lifting mechanism, and the two second cutting units in each second cutting unit assembly may form two parallel second cutting wire saws, which are used for correspondingly cutting the two opposite ears of the edge skin rod 202 at the top of the arc that has been cut off and carried by the second edge skin bearing device. In some embodiments, the second cutting installation structure may be provided with four second cutting units, and the four second cutting units are combined in groups of two to form two second cutting unit assemblies, that is, the two second cutting units in the first second cutting unit assembly are arranged on the first second cutting wire rack, and the two second cutting units in the second second cutting unit assembly are arranged on the second second cutting wire rack, wherein the two second cutting units in the first second cutting unit assembly can form two parallel second cutting wire saws, the first second cutting wire rack and the two second cutting units thereon can be lifted and moved vertically relative to the second cutting installation structure by the first cutting unit lifting mechanism, and are used for correspondingly cutting the two opposite ears in the edge skin rod at the top of the arc that has been cut off and carried on the first edge skin supporting platform, and the two second cutting units in the first second cutting unit assembly can form two parallel second cutting wire saws, the second second cutting wire rack and the two second cutting units thereon can be lifted and moved vertically relative to the second cutting installation structure by the second cutting unit lifting mechanism, and are used for correspondingly cutting the two opposite ears in the edge skin rod at the top of the arc that has been cut off and carried on the second edge skin supporting platform.

[0323] The at least one second cutting unit is disposed on the second cutting installation structure, and the second cutting unit includes: a plurality of second cutting wheels and a second cutting line. Fig.11 and Fig.14 In the illustrated embodiment, the second cutting unit 2333 may include: a plurality of second cutting wheels 2332 and a second cutting wire 2334 , wherein the second cutting wire 2334 is wound around the plurality of second cutting wheels 2332 to form at least one second cutting wire saw 2335 .

[0324] The second cutting wheel 2332 is provided with at least one cutting wire groove for winding the second cutting wire 2334. The cutting wire groove can limit the position of the second cutting wire to control the cutting accuracy. Any second cutting wire saw 2335 is formed by winding the second cutting wire 2334 between two second cutting wheels 2332. The positions of the two second cutting wheels 2332 and the positional relationship between the second cutting wheels 2332 can be used to determine the direction of the second cutting wire saw 2335.

[0325] In such Fig.11 and Fig.14 In the illustrated embodiment, at least one second cutting wire saw 2335 is located in the first direction, and correspondingly, the wheel surface of at least one second cutting wheel 2332 is parallel to the first direction and the third direction, that is, the wheel surface of at least one second cutting wheel 2332 is located in the vertical plane formed by the first direction and the third direction.

[0326] like Fig.11 and Fig.14 As shown, for example, in some embodiments, the second cutting device includes multiple second cutting units, and any second cutting unit 2333 includes multiple second cutting wheels 2332, such as two second cutting wheels 2332, a second cutting wheel 2332a and a second cutting wheel 2332b, the wheel surfaces of the two second cutting wheels 2332 are both located in the vertical plane and are arranged in parallel front and back along the first direction, and the second cutting line 2334 is wound around the second cutting wheel 2332a and the second cutting wheel 2332b to form at least one second cutting wire saw 2335, and the at least one second cutting wire saw 2335 is arranged along the first direction.

[0327] In some embodiments, the second cutting line is wound between the second cutting wheels in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line). Fig.11 and Fig.14 In the illustrated embodiment, the second cutting line 2334 is wound between the two second cutting wheels 2332 in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line).

[0328] The multiple second cutting wheels in the second cutting unit are wound by a circular cutting wire. In this example, the ear cutting device can omit the wire storage drum. The circular cutting wire is driven by the cutting wire driving device to maintain high-speed operation. At the same time, the circular cutting wire can run in the same direction during the cutting operation (the traditional non-circular cutting wire with a wire storage drum runs alternately in forward and reverse directions). In this way, the ear cutting device can achieve high-precision cutting operations, avoiding problems such as ripples on the cutting surface caused by the reversal of the cutting wire or the running speed in the existing cutting method; at the same time, the circular cutting wire can effectively reduce the total length of the cutting wire required for the ear cutting device and reduce production costs.

[0329] In some embodiments, the cutting line driving device is a motor having a power output shaft and the power output shaft is connected to a second cutting wheel, so that the second cutting line can be driven by the wound second cutting wheel to run along the winding direction. Of course, in a specific implementation, the cutting line driving device can also be another driving source such as a hydraulic motor, as long as it can drive the cutting line to run, and this application does not limit it.

[0330] The second cutting unit in the present application may further include a second transition wheel, which is used to change the direction or guide the second cutting line, or the second transition wheel may be used to adjust the tension of the second cutting line. The number of the second transition wheels may be one or more according to layout requirements.

[0331] The second transition wheel, while guiding and pulling the second cutting line, also serves as a tension wheel for adjusting the tension of the second cutting line. The tension wheel is used to adjust the tension of the second cutting line, which can reduce the probability of the second cutting line breaking and reduce consumables.

[0332] For example, in some embodiments, in the second cutting device, any second cutting unit includes multiple second cutting wheels and multiple second transition wheels, for example, two second cutting wheels and two second transition wheels, the wheel surfaces of the two second cutting wheels and the two second transition wheels are all located in the vertical plane and form a quadrilateral (for example, a rectangle, a trapezoid, etc.) as a whole, wherein the two second cutting wheels are arranged at the bottom and in parallel front and back along the first direction, and the two second transition wheels are arranged at the top and in parallel front and back along the first direction, and the second cutting wire is wound around the two second cutting wheels and the two second transition wheels to form at least one second cutting wire saw between the two second cutting wheels, and the at least one second cutting wire saw is arranged along the first direction.

[0333] As mentioned above, the second cutting wire is wound around multiple second cutting wheels or multiple second cutting wheels and multiple second transition wheels to form a second cutting wire saw between the second cutting wheels. Therefore, to adjust the wire length of the second cutting wire saw, it can be achieved by adjusting the spacing between the two second cutting wheels, and the implementation method includes changing the position of at least one of the two second cutting wheels.

[0334] In addition, in some embodiments, the second cutting unit further comprises: a cutting wheel adjustment mechanism for adjusting the position of the second cutting wheel, so that the second cutting wire is sequentially wound around at least one second cutting wire saw formed by the plurality of second cutting wheels and forms a cutting inclination angle with the length direction of the edge leather bar whose arc top has been cut off, that is, by adjusting the position of the second cutting wheel by the cutting wheel adjustment mechanism, the second cutting wire saw can still have other changes. Fig.11 and Fig.14In the illustrated embodiment, the two second cutting wheels 2332a and 2332b are arranged in parallel along the first direction, and the second cutting line 2334 is wound around the two second cutting wheels 2332a and 2332b to form a second cutting wire saw 2335 between the two second cutting wheels 2332a and 2332b. The second cutting wire saw 2335 is arranged along the first direction, but is not limited to this. In other embodiments, the position of the second cutting wire saw 2335 may be located in a vertical plane and arranged at a first direction angle to the first direction, and the vertical plane is composed of the first direction and the third direction, and the first direction angle is less than or equal to 45° (≤±45°), that is, the routing direction of the second cutting wire saw 2335 may be located in the same vertical plane as the first direction and form an angle less than or equal to 45° (≤±45°) with the first direction. In this implementation, in the third direction, one of the two second cutting wheels is at the bottom and the other second cutting wheel is at the top, for example, the second cutting wheel 2332a is at the bottom and the second cutting wheel 2332b is at the top (the deflection angle formed by the second cutting wire saw formed by the second cutting wheel 2332a at the bottom and the second cutting wheel 2332b at the top and the first direction is referred to as a positive deflection angle) or the second cutting wheel 2332b is at the top and the second cutting wheel 2332a is at the bottom (the second cutting wire saw formed by the second cutting wheel 2332a at the top and the second cutting wheel 2332b at the top and the first direction is referred to as a positive deflection angle). The deflection angle is called a negative deflection angle). Thus, when cutting the ear, the lower part of the second cutting wire saw 2335 first enters the edge skin bar 202 with the top of the arc cut off, and in the process of descending and advancing, the upper part of the second cutting wire saw 2335 enters the edge skin bar 202 with the top of the arc cut off, and continuously cuts the edge skin bar 202 with the top of the arc cut off. Finally, the lower part of the second cutting wire saw 2335 first exits the edge skin bar 202 with the top of the arc cut off, and then the upper part of the second cutting wire saw 2335 exits later, until the ear in the edge skin bar 202 with the top of the arc cut off is cut off. The first direction deflection angle can be changed according to the cutting process requirements and the size specifications of the edge skin bar to be cut, for example, by changing the position of one or both of the second cutting wheel 2332a and the second cutting wheel 2332b associated with the second cutting wire saw 2335.

[0335] In some embodiments, the second cutting unit further includes a tension adjustment mechanism. In the wire cutting process, the cutting wire tension affects the yield and processing accuracy of the cutting process, and the tension adjustment mechanism detects the tension and adjusts the tension so that the cutting wire tension reaches a certain threshold value and maintains a constant value during cutting or takes the constant value as a certain range allowed by the center of the value.

[0336] In some embodiments, the tension adjustment mechanism is associated with a cutting wheel (or transition wheel), and the cutting wheel (or transition wheel) in the wire cutting unit serves as a tensioning wheel for adjusting the tension of the cutting wire while achieving guided traction on the cutting wire.

[0337] The tension wheel is used to adjust the tension of the cutting wire, which can reduce the probability of the cutting wire breaking and reduce consumables. In the cutting operation, the cutting wire plays a vital role, but even the best cutting wire has limited elongation and wear resistance, which means that the cutting wire will gradually become thinner during continuous operation until it is finally broken. Therefore, current wire cutting equipment generally has a cutting wire tension compensation mechanism to compensate for the elongation of the cutting wire during its reciprocating movement, and the use of a tension wheel is one means of implementation.

[0338] like Fig.11 and Fig.14 As shown, for example, in some embodiments, the tension adjustment mechanism can perform tension detection and adjust the tension according to the tension detection result. The method of adjusting the tension is not limited, for example, it can be achieved by adjusting the second cutting wheel 2332. In some cases, when it is detected that the tension does not reach the set requirement, the position of at least one of the two second cutting wheels 2332 is adjusted, for example, the second cutting wheel 2332 is moved outward to expand the distance between the two second cutting wheels 2332, and the tension is increased. In some cases, when it is detected that the tension exceeds the set requirement, the position of at least one of the two second cutting wheels 2332 is adjusted, for example, the second cutting wheel 2332 is moved inward to reduce the distance between the two second cutting wheels 2332, and the tension is reduced.

[0339] In some embodiments, the second cutting unit may further include: at least one second distance adjustment mechanism, configured to drive the plurality of second cutting wheels to move relative to the second cutting mounting structure in a direction perpendicular to the cutting wheel surface.

[0340] The second cutting assembly can realize the switching of the second cutting wire between different cutting grooves of the second cutting wheel based on the second distance adjustment mechanism, or adjust the position of the second cutting wire saw (for example, in the first direction) to change the cutting position (or processing specifications) relative to the silicon rod. In practical applications, the second distance adjustment mechanism may, for example, include: a screw, which is arranged along the orthogonal direction of the wheel surface of the second cutting wheel and is threadedly connected to the second cutting wheel; a driving source for driving the screw to rotate. Alternatively, the second distance adjustment mechanism may, for example, include: a telescopic member, which is arranged along the orthogonal direction of the wheel surface of the second cutting wheel and is associated with the second cutting wheel; a driving source for driving the telescopic member to perform telescopic movement along the orthogonal direction of the wheel surface of the second cutting wheel. Alternatively, the second distance adjustment mechanism may, for example, include: a rack, which is arranged on the second cutting wheel along the orthogonal direction of the wheel surface of the second cutting wheel; a transmission gear, which is meshed with the rack; a driving source for driving the transmission gear to rotate.

[0341] The cutting unit lifting mechanism is used to drive the at least one second cutting unit to move vertically relative to the second cutting installation structure.

[0342] In some embodiments, the at least one second cutting unit is movably mounted on the second cutting mounting structure via a second cutting wire rack, that is, the at least one second cutting unit is mounted on the second cutting wire rack, and the second cutting wire rack and the at least one second cutting unit thereon are driven to move vertically relative to the second cutting mounting structure via a cutting unit lifting mechanism.

[0343] In some embodiments, the second cutting units correspond to the second cutting wire racks one by one, that is, each second cutting unit is movably mounted on the second cutting mounting structure through a corresponding second cutting wire rack.

[0344] In some embodiments, the plurality of second cutting units share a second cutting wire rack, that is, the plurality of second cutting units are movably mounted on the second cutting mounting structure through a corresponding second cutting wire rack. Fig.11 and Fig.14 In the illustrated embodiment, the second cutting mounting structure 2331 may be provided with four second cutting units 2333, and the four second cutting units 2333 may be combined in groups of two to form two second cutting unit assemblies, and the two second cutting unit assemblies may be arranged on the same second cutting wire rack, and the second cutting wire rack and the four second cutting units 2333 thereon may be lifted and lowered vertically relative to the second cutting mounting structure 2331 by a cutting unit lifting mechanism, and the two second cutting units in each second cutting unit assembly may form two parallel second cutting wire saws, which are used for correspondingly cutting the two opposite ears of the edge skin rod 202 at the top of the arc that has been cut off and carried by the second edge skin bearing device.

[0345] In some implementations, the cutting unit lifting mechanism may include a lifting rail, a slider, and a lifting drive unit, wherein the lifting rail is arranged on the second cutting installation structure along a third direction, the slider is arranged on the second cutting wire rack and is adapted to the corresponding lifting rail, and the lifting drive unit is used to drive the second cutting wire rack to move up and down along the lifting rail. In actual applications, in order to enable the second cutting wire rack to be stably lifted and lowered on the second cutting installation structure, a double rail design may be adopted, that is, two lifting rails are adopted, and the two lifting rails are arranged in parallel. In addition, the lifting drive unit may further include a lifting screw and a lifting motor, wherein the lifting screw is along the third direction and connected to the second cutting wire rack, and the lifting motor (the lifting motor may be, for example, a servo motor) is connected to the lifting screw. In this way, the lifting motor drives the lifting screw to rotate, so that the second cutting wire rack can be lifted and lowered along the lifting rail. The implementation method of the lifting drive unit is not limited to this. Other components that can drive the second cutting wire rack to move up and down along the lifting guide rail are still applicable. For example, the lifting drive unit may include a lifting rack, a driving gear meshing with the lifting rack, and a driving motor that drives the driving gear to rotate.

[0346] In such Fig.11 and Fig.14 In the shown embodiment, the second cutting device includes four second cutting units, and the four second cutting units are combined in groups of two to form two second cutting unit assemblies. The two second cutting unit assemblies can be arranged on the same second cutting wire rack. The second cutting wire rack and the four second cutting units thereon can be lifted and moved vertically relative to the second cutting mounting structure by a cutting unit lifting mechanism. The two second cutting units in each second cutting unit assembly can form two parallel second cutting wire saws, which are used to correspondingly cut the two opposite ears in the edge skin rod stack carried by the second edge skin carrying device.

[0347] Of course, in certain other embodiments, for example, the second cutting device includes four second cutting units, and the four second cutting units are combined in groups of two to form two second cutting unit assemblies, and each second cutting unit assembly is arranged on a second cutting wire rack, that is, the first second cutting unit assembly is arranged on the first second cutting wire rack, and the second second cutting unit assembly is arranged on the second second cutting wire rack, wherein the first second cutting wire rack can be lifted and moved vertically relative to the second cutting mounting structure by the first cutting unit lifting mechanism, and the second second cutting wire rack can be lifted and moved vertically relative to the second cutting mounting structure by the second cutting unit lifting mechanism, and the two second cutting units in each second cutting unit assembly can form two parallel second cutting wire saws, which are used to correspondingly cut the two opposite ears in the edge skin rod stack carried by the second edge skin carrying device.

[0348] The ear cutting device also includes a cutting and transporting device for transporting the edge skin bar with the arc top cut off to the second edge skin carrying device. Fig.11 and Fig.14 In the illustrated embodiment, the ear cutting device 23 further includes a cutting and transporting device 235 for transporting the edge skin rod 202 whose arc top has been cut off to a second edge skin carrying device. In certain embodiments, the cutting and transporting device may be, for example, a transport fixture or a suction cup transporting manipulator. Taking the suction cup transporting manipulator as an example, the suction cup transporting manipulator can be flexibly changed, can be raised and lowered, translated left and right, moved forward and backward, and rotated, etc. It can suck the edge skin rod whose arc top has been cut off from the first edge skin carrying device of the arc top cutting device, and transfer it to the second edge skin carrying device of the ear cutting device, so that the bottom surface of the edge skin rod whose arc top has been cut off is at the bottom and the top surface is at the top (or the bottom surface is at the top and the top surface is at the bottom), and the two ears are located on opposite sides along the second direction.

[0349] The ear cutting device further comprises an ear unloading device for unloading the ears cut off after the ear cutting operation. In some embodiments, the ear unloading device may be, for example, an ear conveyor belt. For example, an ear conveyor belt may be provided on opposite sides of the second edge skin supporting device. In some embodiments, such as Fig.11 and Fig.14As shown, the ear cutting equipment 23 also includes an ear unloading device, which may include: a movable pushing member 2371 and a unloading ramp 2373, the movable pushing member 2371 is arranged at the bottom of the second cutting mounting structure 2331, the movable pushing member 2371 corresponds to the second side skin support platform 2311 in height and is located at the rear end of the second side skin support platform 2311, the movable pushing member 2371 can be driven by a pushing driving mechanism 2372 to move along the first direction to move relative to the second side skin support platform 2311, the movable pushing member 2371 is provided with a plurality of pushing blocks or pushing strips corresponding to the plurality of ears 203, the number of the pushing blocks or pushing strips is consistent with the number of ears 203, and the setting spacing of the pushing blocks or pushing strips is consistent with the spacing of the cut ears 203. The ejection drive mechanism 2372 may include a chain, a drive gear, and a drive motor, wherein the chain is associated with the mobile ejection member 2371, the drive gear is meshed with the chain, and the drive motor is connected to the drive gear. The drive motor can drive the drive gear to rotate forward and reverse, driving the rack and its associated mobile ejection member 2371 to move forward or backward along the first direction. The discharge ramp 2373 is located at the front end of the second side skin support platform 2311 and is connected to the second side skin support platform 2311. The lower slope of the discharge ramp 2373 may correspond to an ear collection box 2375. In this way, when the ear unloading device is used to unload the ear, the movable pushing member 2371 is driven along the first direction toward the second side skin supporting platform 2311, and the pushing block or pushing strip on the movable pushing member 2371 pushes the corresponding ear 203 and makes the ear 203 move along the first direction until the ear 203 enters the unloading ramp 2373 and then slides into the ear collection box 2375.

[0350] The ear cutting device also includes a side strip unloading device for unloading the cut ear side strip.

In some embodiments, the side strip unloading device can be, for example, a handling fixture or a suction cup handling manipulator. The side strip unloading device can be an independent device or shared with the cutting and handling device.

[0351] When performing ear cutting operations using the ear cutting device in the edge skin assembly line system of the present application, first, the edge skin rod with the arc top cut off is transferred to the second edge skin supporting device of the ear cutting device using the cutting and transporting device, wherein the edge skin rod with the arc top cut off is placed on the second edge skin supporting device in a manner such that the bottom surface is at the bottom and the top surface is at the top (or the bottom surface is at the top and the top surface is at the bottom) and the two ears are located on opposite sides along the second direction; then, the edge skin rod with the arc top cut off is positioned using the second edge skin positioning mechanism to stabilize it. Place; then, use the cutting unit lifting mechanism to drive the at least one second cutting unit to descend vertically, and the at least one second cutting wire saw in the at least one second cutting unit contacts and cuts the edge leather bar whose arc top has been cut off, until the at least one second cutting wire saw completely passes through the edge leather bar whose arc top has been cut off to complete the ear cutting operation, and cut off the ear of the edge leather bar whose arc top has been cut off to form an edge leather strip with a rectangular cross-section; use the ear unloading device to unload the ear, and use the edge leather strip unloading device to unload the edge leather strip whose ear has been cut off.

[0352] In the above embodiments, in the ear cutting equipment, the second cutting device includes: a second cutting mounting structure, at least one second cutting unit, and a cutting unit lifting mechanism. The cutting unit lifting mechanism is used to drive at least one second cutting unit to move vertically up and down to perform ear cutting operations on the edge skin rod whose arc top has been cut off, but this is not limited to this. The ear cutting equipment can still be modified in other ways.

[0353] In some embodiments, the second cutting device may include: a second cutting installation structure, at least one second cutting unit, and a cutting unit translation mechanism.

[0354] The second cutting installation structure is arranged on the cutting machine base and corresponds to the second cutting area. In some embodiments, the second cutting installation structure can be, for example, a mounting bracket, a mounting beam, a mounting column, or the like.

[0355] The second cutting unit includes: a plurality of second cutting wheels and a second cutting wire. For example, in some embodiments, the second cutting unit may include: a plurality of second cutting wheels and a second cutting wire, wherein the second cutting wire is wound around the plurality of second cutting wheels to form at least one second cutting wire saw.

[0356] The second cutting wheel is provided with at least one cutting wire groove for winding the second cutting wire, and the cutting wire groove can limit the position of the second cutting wire to control the cutting accuracy. Any second cutting wire saw is formed by winding the second cutting wire between two second cutting wheels, and the positions of the two second cutting wheels and the positional relationship between the second cutting wheels can be used to determine the direction of the second cutting wire saw.

[0357] In some embodiments, at least one second cutting wire saw is located in the third direction, and correspondingly, the wheel surface of at least one second cutting wheel is parallel to the second direction and the third direction, that is, the wheel surface of at least one second cutting wheel is located in the vertical plane formed by the second direction and the third direction.

[0358] For example, in some embodiments, the second cutting device includes a plurality of second cutting units, and any second cutting unit includes a plurality of second cutting wheels, such as four second cutting wheels, the wheel surfaces of the four second cutting wheels are all located in the vertical plane and form a quadrilateral (for example, a rectangle, a trapezoid, etc.) as a whole, wherein two second cutting wheels are arranged in parallel up and down in the front and along the third direction, and the other two second cutting wheels are arranged in parallel up and down in the back and along the third direction, and the second cutting wire is wound around the four second cutting wheels to form at least one second cutting wire saw (for example, a second cutting wire saw is formed between the two front second cutting wheels), and the at least one second cutting wire saw is arranged along the third direction. In some embodiments, any second cutting unit includes two second cutting wheels, and the second cutting wire is wound around the four second cutting wheels to form at least one second cutting wire saw, and the at least one second cutting wire saw is arranged along the third direction.

[0359] In some embodiments, the second cutting line is wound between the second cutting wheels in an end-to-end manner to form an annular cutting line (also referred to as a closed-loop cutting line).

[0360] The second cutting unit in the present application may further include a second transition wheel, which is used to change the direction or guide the second cutting line, or the second transition wheel may be used to adjust the tension of the second cutting line. The number of the second transition wheels may be one or more according to layout requirements.

[0361] The second transition wheel, while guiding and pulling the second cutting line, also serves as a tension wheel for adjusting the tension of the second cutting line. The tension wheel is used to adjust the tension of the second cutting line, which can reduce the probability of the second cutting line breaking and reduce consumables.

[0362] For example, in some embodiments, the second cutting device includes multiple second cutting wheels and multiple second transition wheels, for example, two cutting wheels and two transition wheels, the wheel surfaces of the two cutting wheels and the two transition wheels are all located in the vertical plane and form a quadrilateral (for example, a rectangle, a trapezoid, etc.) as a whole, wherein the two second cutting wheels are in front and arranged in parallel up and down along the third direction, the two second transition wheels are in the back and arranged in parallel up and down along the third direction, the second cutting wire is wound around the two cutting wheels and the two transition wheels to form at least one second cutting wire saw (for example, a second cutting wire saw is formed between the two second cutting wheels), and at least one second cutting wire saw is arranged along the third direction.

[0363] As mentioned above, the second cutting wire is wound around multiple second cutting wheels or multiple second cutting wheels and multiple second transition wheels to form a second cutting wire saw between the second cutting wheels. Therefore, to adjust the wire length of the second cutting wire saw, it can be achieved by adjusting the spacing between the two second cutting wheels where the second cutting wire saw is located. The implementation method includes changing the position of at least one of the two second cutting wheels.

[0364] In addition, the second cutting wire saw may still have other changes. For example, in other embodiments, the position of the second cutting wire saw may be located in a vertical plane and arranged at a third direction angle to the third direction, the vertical plane is composed of the second direction and the third direction, and the third direction angle is less than or equal to 45° (≤±45°), that is, the routing direction of the second cutting wire saw may be located in the same vertical plane as the third direction and form an angle less than or equal to 45° (≤±45°) with the third direction. In this implementation, in the third direction, one second cutting wheel is in front and the other second cutting wheel is in the back (the deflection angle formed by the second cutting wire saw formed by the upper second cutting wheel in front and the lower second cutting wheel in the back and the third direction can be called a positive deflection angle, or the deflection angle formed by the second cutting wire saw formed by the upper second cutting wheel in the back and the lower second cutting wheel in the front and the third direction can be called a negative deflection angle), so that when performing truncation cutting, the front part of the second cutting wire saw first enters the edge skin bar stack and the rear part of the second cutting wire saw enters the edge skin bar stack later during the translational advancement process, and the edge skin bar stack is continuously cut, and finally the front part of the second cutting wire saw first exits the edge skin bar stack and then the rear part of the second cutting wire saw exits later, until the edge skin bar stack is truncated. The deflection angle in the third direction can be changed according to the cutting process requirements and the size specifications of the edge skin bar to be cut, for example, the angle of the deflection angle in the third direction can be adjusted by changing the position of one or two second cutting wheels associated with the second cutting wire saw.

[0365] In some embodiments, the second cutting unit further includes a tension adjustment mechanism.

[0366] In some embodiments, the tension adjustment mechanism is associated with a transition wheel, and the transition wheel in the wire cutting unit serves as a tension wheel for adjusting the tension of the cutting wire while achieving the guiding and traction of the cutting wire.

[0367] In some embodiments, the second cutting unit may further include: at least one second distance adjustment mechanism, configured to drive the plurality of second cutting wheels to move relative to the second cutting mounting structure in a direction perpendicular to the cutting wheel surface.

[0368] The cutting unit translation mechanism is used to drive the at least one second cutting unit to translate relative to the third edge skin bearing device.

[0369] In some embodiments, the cutting unit translation mechanism is used to drive at least one second cutting unit to translate relative to the second cutting installation structure, so that the at least one second cutting unit translates relative to the third edge skin supporting device.

[0370] The cutting unit translation mechanism may include: a translation guide rail and a translation drive unit. The translation guide rail is arranged along the second direction and is used to set the at least one second cutting unit. The translation drive unit is used to drive the at least one second cutting unit to move along the translation guide rail.

[0371] In some embodiments, the translation drive unit includes a translation rack, a driving gear, and a driving source. The translation rack is arranged along the second direction and is parallel to the translation guide rail. The driving gear is arranged on at least one second cutting unit or a second cutting wire rack associated with the at least one second cutting unit, and is meshed with the translation rack to drive the at least one second cutting unit to move along the translation guide rail. The driving gear is driven to rotate by the driving source, and the gear teeth of the driving gear are meshed with the translation rack, and follow the movement of the translation rack, so that at least one second cutting unit connected to the driving gear or the second cutting wire rack associated with the at least one second cutting unit moves accordingly on the translation guide rail. The driving source is, for example, a driving motor.

[0372] In some embodiments, the mobile drive unit includes a translation screw and a drive source, wherein the translation screw is arranged along the second direction and is associated with at least one second cutting unit or a second cutting wire frame associated with the at least one second cutting unit, and the drive source is used to drive the translation screw to rotate so that the associated at least one second cutting unit moves along the translation guide rail. The drive source is, for example, a drive motor.

[0373] When using the ear cutting equipment to perform the ear cutting operation, first, the edge skin rod with the arc top cut off is transferred to the second edge skin carrying device of the ear cutting equipment by using the cutting and transporting device. At this time, the edge skin rod with the arc top cut off is placed on the second edge skin carrying device in a manner that the bottom surface is at the bottom and the top surface is at the top (or the bottom surface is at the top and the top surface is at the bottom) and the two ears are located on opposite sides along the second direction; the second cutting line is driven by the cutting line driving device to run in the winding direction, and the at least one second cutting unit is driven by the cutting unit translation mechanism to translate along the first direction to achieve relative feeding with the edge skin rod with the arc top cut off carried by the third edge skin carrying device, so that the second cutting line saw can cut the edge skin rod with the arc top cut off and cut off the ears of the edge skin rod with the arc top cut off.

[0374] Of course, in some embodiments, the second side skin supporting device is of mobile design, that is, the second side skin supporting device may be equipped with a supporting device translation mechanism for driving the second side skin supporting device to translate relative to the second cutting device. Regarding the supporting device translation mechanism, reference may be made to the aforementioned cutting unit translation mechanism, which will not be described in detail here.

[0375] The edge leather assembly line system of the present application also includes a grinding device for grinding the bottom surface of the edge leather strip output by the ear cutting device.

[0376] In this application, Fig.11 and Fig.14 In the embodiment shown, a side skin flipping and conveying device 26 is further included between the ear cutting device 23 and the surface grinding device 24. The side skin flipping and conveying device 26 is located in the flipping and conveying area between the ear cutting device 23 and the surface grinding device 24, and is used to flip the side skin strip 204 of the ear that has been cut off and convey it to the surface grinding device 24. In this embodiment, the side skin strip of the ear that has been cut off output by the ear cutting device is placed on the second side skin carrying device of the ear cutting device in a manner that the bottom surface is at the bottom and the top surface is at the top, and the surface grinding device performs a surface grinding operation on the bottom surface of the side skin strip of the ear that has been cut off. Therefore, it is also necessary to flip the side skin strip of the ear that has been cut off so that it is placed in a manner that the bottom surface is at the top and the top surface is at the bottom. Of course, the above is only an exemplary description, but it is not limited to this. For example, in some embodiments, the side skin strip of the ear that has been cut off can be directly flipped by using the side skin loading and unloading device in the ear cutting device, so the flipping operation of the side skin strip by the side skin flipping and conveying device can be omitted. Alternatively, for example, in some embodiments, the grinding device can grind the edge leather strip with the ear portion cut off when it is placed with the bottom surface at the bottom and the top surface at the top, thereby eliminating the aforementioned edge leather flipping and conveying equipment flipping operations on the edge leather strip.

[0377] In some embodiments, the edge skin turning and conveying device may further include an edge skin conveying device and an edge skin turning device. Fig.14 In the illustrated embodiment, the edge skin flipping and conveying device includes an edge skin conveying device and an edge skin flipping device, wherein the edge skin conveying device is used to transfer the edge skin strip 204 with the ear removed from the second cutting area to the edge skin flipping device, and the edge skin flipping device is used to flip the edge skin strip 204 with the ear removed. As mentioned above, in some embodiments, when it is not necessary to flip the edge skin strip with the ear removed, the edge skin flipping device can be omitted.

[0378] The edge conveying device may be, for example, a conveyor belt or a conveyor chain.

[0379] The edge skin flipping device may include an edge skin flipping device. The edge skin flipping device is used to flip the edge skin strip of the ear that has been cut off. In some embodiments, the edge skin flipping device includes a flipping mechanism and at least one edge skin clamp provided on the flipping mechanism, and the at least one edge skin clamp is used to clamp the edge skin strip of the ear that has been cut off. In some embodiments, the flipping mechanism may include a rotating shaft and a rotating motor, and the rotating shaft is horizontally arranged.

[0380] The edge leather clamp is arranged on the flipping mechanism, and is used to clamp the edge leather strip with the ears cut off, wherein the edge leather clamp flips along with the rotation of the flipping mechanism. For example, in the initial state, the edge leather clamp is located at one side of the flipping mechanism and is in a horizontal placement state, and the edge leather strip with the ears cut off is transported and placed in the clamping space of the edge leather furniture. At this time,...
