Description

[0001] This application is a divisional application filed pursuant to Article 48 of the Implementing Regulations of the Patent Law. Its parent application is Chinese Utility Model Application No. 202421177847.2, filed on May 27, 2024, with a priority date of June 9, 2023 and priority number 202310683097.X, entitled "Edge Skin Assembly Line System," and the applicant is Shanghai Rijin Machine Tool Co., Ltd. The entire contents of the parent application are incorporated herein by reference. Technical Field

[0002] This application relates to the field of silicon workpiece processing technology, and in particular to an edge-skin assembly line system. Background Technology

[0003] Currently, with increasing societal emphasis on and openness to the use of green and renewable energy, the photovoltaic solar power generation field is receiving more and more attention and development. In the photovoltaic power generation field, typical crystalline silicon solar cells are manufactured on high-quality silicon wafers, which are cut from pulled or cast silicon ingots using a multi-wire saw and subsequent processing.

[0004] The existing silicon wafer manufacturing process, taking monocrystalline silicon products as an example, generally includes the following steps: First, a silicon rod cutting machine is used to slice the original long silicon rod to form multiple short silicon rods; after slicing, a silicon rod squaring machine is used to cut the slits into rectangular (or near-rectangular) silicon rods; then, each squared silicon rod is ground, chamfered / rounded, etc., to ensure that the surface of the silicon rod meets the corresponding flatness and dimensional tolerance requirements; finally, a slicing machine is used to slice the silicon rods to obtain silicon wafers.

[0005] In the process of squaring monocrystalline silicon rods, edge scraps are generated. These edge scraps have an arc-shaped cross-section, specifically consisting of a rectangular base and a slightly curved surface opposite the base. These edge scraps are typically recycled or used as seed crystals for high-efficiency polycrystalline ingot casting. Failure to fully utilize them results in material waste and low utilization rates of monocrystalline silicon rods. Therefore, improving material recycling is a pressing issue that needs to be addressed. Summary of the Invention

[0006] In view of the shortcomings of the above-mentioned related technologies, the purpose of this application is to disclose an edge skin production line system to solve the problems of material waste caused by the inability to fully utilize edge skin materials in the existing related technologies.

[0007] To achieve the above and other related objectives, this application discloses an edge-skin assembly line system for processing edge-skin bars. The edge-skin bars have an arc-shaped cross-section, including a rectangular base and a minor arc surface opposite to the base. The edge-skin assembly line system includes: an arc-top cutting device for cutting the arc-top of the edge-skin bar along its width direction to remove the arc-top of the edge-skin bar; a stacking device for stacking multiple edge-skin bars with the arc-top removed to form an edge-skin bar stack; a cutting device for cutting the edge-skin bar stack along its length direction to form multiple edge-skin bar stack segments; and an ear-cutting device for cutting the ear-shaped segments of the edge-skin bar stack along its thickness direction to remove the ear-shaped portion of each edge-skin bar in the stack segments, forming an edge-skin sheet with a rectangular cross-section.

[0008] The edge strip processing system disclosed in this application includes an arc-top cutting device, a stacking device, a cutting device, and an ear-shaped cutting device. The arc-top cutting device cuts the edge strip to remove the arc-top of the edge strip. The stacking device stacks multiple edge strips with the arc-top removed to form an edge strip stack. The cutting device cuts the edge strip stack to form multiple edge strip stack segments. The ear-shaped cutting device cuts the ear-shaped segments of the edge strip stack to remove the ears of each edge strip in the stack segments. Thus, the edge strip with an arc-shaped cross-section can be cut and processed to have a rectangular cross-section. Through the continuous processing, the processing efficiency of edge strips is improved and their reuse is enhanced, saving resources and costs. Attached Figure Description

[0020] The following specific embodiments illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification.

[0021] Although the terms first, second, etc., are used in some instances herein to describe various elements or parameters, these elements or parameters should not be limited by these terms. These terms are used only to distinguish one element or parameter from another. For example, a first direction may be referred to as a second direction, and similarly, a second direction may be referred to as a first direction; as another example, a first cutting device may be referred to as a second cutting device, and similarly, a second cutting device may be referred to as a first cutting device, without departing from the scope of the various described embodiments.

[0022] In related silicon rod processing operations, several processes are involved, such as cutting and squaring, grinding, and chamfering.

[0023] Generally, most existing silicon rods are cylindrical in shape. By using a silicon rod squaring device, the silicon rod is cut into a rectangular (or square) cross-section after squaring, meaning the cut silicon rod has a cuboid-like shape (or possibly a cube-like shape). The rectangular shape includes rectangles with orthogonal adjacent sides or whose included angle is within a predetermined range, rectangles with rounded corners between adjacent sides, and rectangles with connecting short sides between adjacent sides, etc.

[0024] Taking monocrystalline silicon rods as an example, in some related technologies, the process of forming monocrystalline silicon rods may include: first, using a silicon rod slicing machine to slice the original long silicon rod to form multiple short silicon rod segments; after slicing, using a silicon rod squaring machine to cut and square the short silicon rods to form monocrystalline silicon rods with a rectangular cross-section. For the specific implementation of using a silicon rod slicing machine to slice the original long silicon rod to form multiple short silicon rod segments, please refer to patent publications such as CN105856445A and CN105946127A. For the specific implementation of using a silicon rod squaring machine to cut and square the short silicon rods to form monocrystalline silicon rods with a rectangular cross-section, please refer to patent publications such as CN105818285A. However, the formation process of monocrystalline silicon rods is not limited to the aforementioned technologies. In optional examples, the formation process of monocrystalline silicon rods may also include: first, using a full silicon rod squaring machine to cut and squaring the original long silicon rod to form a long monocrystalline 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 monocrystalline silicon rod to form a short crystal silicon rod.

[0025] After a cylindrical single-crystal silicon rod is cut into a rectangular shape using a squaring device, a grinding device can be used to perform operations such as grinding, chamfering (or rounding) on ​​the rectangular silicon rod. For specific implementation methods of grinding, chamfering (or rounding) the rectangular silicon rod using the aforementioned grinding device, please refer to, for example, patent publications such as CN105835247A.

[0026] In the squaring process of silicon rods, edge strips are formed after the silicon rod is squared. These edge strips are called edge strip rods. The edge strip rods have a certain length, the same as the original silicon rod, and their cross-section is generally arc-shaped (including the bottom edge and the inferior arc). That is, the edge strip rod includes a rectangular bottom surface and an inferior arc surface opposite the bottom surface. In some implementations, the edge strip rods are generally recycled or used as seed crystals for polycrystalline ingots, but this results in a low utilization rate of the monocrystalline silicon rod. In some implementations, the edge strip rods are cut into edge strip sheets with a roughly rectangular cross-section for reuse, but this still has problems such as complex cutting equipment and low cutting efficiency.

[0027] In view of this, the first aspect of this application proposes a side-skin assembly line system.

[0028] The edge leather assembly line system includes an arc-top cutting device, a stacking device, a cutting device, and an ear-shaped cutting device. The arc-top cutting device cuts the arc-top of the edge leather bar to remove it. The stacking device stacks multiple edge leather bars with the arc-top removed to form an edge leather bar stack. The cutting device cuts the edge leather bar stack to form multiple edge leather bar stack segments. The ear-shaped cutting device cuts the ear-shaped segments of the edge leather bar stack to remove the ears of each edge leather bar in the stack segments. In this way, the edge leather bars with an arc-shaped cross-section can be processed into edge leather pieces with a rectangular cross-section. Through assembly line operation, the processing efficiency of edge leather bars is improved, their reuse is enhanced, and resources and costs are saved.

[0029] In the embodiments provided in this application, in order to clarify the definition of direction and the way different structures operate, a three-dimensional space is defined by a first direction, a second direction, and a third direction. The first direction, the second direction, and the third direction are all straight lines 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 that is perpendicular to the horizontal plane. It can also be called a perpendicular line direction, vertical direction, up and down direction, or rising and falling direction.

[0030] In the embodiments provided in this application, the cross-section of the edge bar is arc-shaped, including a rectangular bottom surface and a minor arc surface opposite to the bottom surface. The end faces of the edge bar refer to two opposite surfaces along the length direction of the edge bar, and the two end faces are arc-shaped.

[0031] Please see Figure 1 and Figure 2 , Figure 1 The diagram shown is an overall schematic diagram of one embodiment of the edge-skinning continuous operation system of this application. Figure 2 Displayed as Figure 1 A schematic diagram of the status of each process involved in the edge bar operation of the edge bar production line system.

[0032] like Figure 1 As shown, an embodiment of this application discloses a silicon rod cutting and grinding integrated machine, including: an arc top cutting device 11, a stacking device 13, a cutting device 15, and an ear cutting device 17.

[0033] The arc-top cutting device is used to perform arc-top cutting operations on the edge bar to remove the arc-top of the edge bar. Please refer to [link / reference]. Figure 3 Displayed as Figure 1 A schematic diagram of the structure of the mid-arc top cutting equipment. (In...) Figure 1 and Figure 3In the embodiment shown, the arc-top cutting device 11 is used to perform arc-top cutting on the edge bar along the width direction of the edge bar to remove the arc-top of the edge bar. After removing the arc-top of the edge bar, the edge bar with the arc-top removed forms a top surface with a smaller width, a bottom surface with a larger width, and ears with curved surfaces on both sides located between the top surface and the bottom surface.

[0034] In some embodiments, the arc-top cutting device includes: a first edge-skin bearing device and a first cutting device, wherein the first edge-skin bearing device is used to bear the edge-skin bar, and the first cutting device is used to perform arc-top cutting on the edge-skin bar carried by the first edge-skin bearing device to remove the arc-top of the edge-skin bar. Here, the edge-skin bar has an arc-shaped cross-section, including a rectangular base and a lesser arc surface opposite the base. In such cases... Figure 1 and Figure 3 In the embodiment shown, the arc-top cutting device 11 includes: a first edge skin bearing device 111 and a first cutting device 113.

[0035] Generally, the method of using a first cutting device to perform arc-top cutting on the edge bar carried by a first edge bar support device to remove the arc-top of the edge bar includes using relative movement between the first cutting device and the first edge bar support device to perform the arc-top cutting operation. In some embodiments, the first edge bar support device is a fixed edge bar support device and the first cutting device is a movable cutting device. During 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 bar support device and the edge bar it carries. In some embodiments, the first edge bar support device is a movable edge bar support device and the first cutting device is a movable cutting device. During the arc-top cutting operation, the first cutting device is driven to move and the first edge bar support device is driven to move, that is, the first cutting device moves towards the first edge bar support device and the edge bar it carries. In some embodiments, the first edge skin support device is a movable edge skin support device and the first cutting device is a fixed cutting device. When performing arc top cutting operations, the first edge skin support device is driven to move, that is, the first edge skin support device and the edge skin bar it carries move relative to the first cutting device.

[0036] In some embodiments, the first edge skin carrying device includes at least one first edge skin carrying component. In some implementations, the first edge skin carrying component may be fixed, that is, the first edge skin carrying component in the first edge skin carrying device is fixedly disposed in the first cutting area. In some implementations, the first edge skin carrying component is movable. For example, the first edge skin carrying component in the first edge skin carrying device is provided with a rotation pivot, which can drive the associated first edge skin carrying component to switch between the first cutting area and other working areas. 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., or for example, the other working areas may include a loading area and an unloading area, etc.

[0037] In some embodiments, the first edge skin carrying device includes at least two first edge skin carrying components, which are switched between different working areas via a conversion mechanism. For example, in some embodiments, the first edge skin carrying device includes two first edge skin carrying components, which can be arranged at a certain angle. For example, the working area may include a loading area and a first cutting area, which are arranged opposite to each other. The two first edge skin carrying components can be arranged at 180°, and a conversion mechanism is provided between the two first edge skin carrying components. Thus, when one first edge skin carrying component is located in the loading area, the other first edge skin carrying component is located in the first cutting area. By switching ±180° through the conversion mechanism, the two first edge skin carrying components can be driven to switch between the loading area and the first cutting area. For example, the working area may include a loading area and a first cutting area, which are set at a 90° angle. Two first edge-skin bearing assemblies may also be set at a 90° angle, with a switching mechanism between them. Thus, when one first edge-skin bearing assembly is in the loading area, the other is in the first cutting area. The switching mechanism, by switching ±90°, can drive the two first edge-skin bearing assemblies to switch between the loading area and the first cutting area. The loading area is merely illustrative; in other embodiments, it may be a loading / unloading area, a discharge area, or another working area. The angle between the loading area and the first cutting area can also vary, for example, to 100°, 110°, 120°, 130°, 140°, 150°, or other angles, without limitation. Furthermore, the working area is not limited to one; it may include two, three, or more. For example, the working area may include a loading area, a first cutting area, and an unloading area, which are arranged at an angle (e.g., 90°, 120°, etc.). Thus, a conversion mechanism can be used to switch the first edge-supporting assembly between the various working areas by changing the angle between ±90° and ±120°. In some implementations, the conversion mechanism may be, for example, a rotating pivot driven by a motor.

[0038] In such Figure 1 and Figure 3 In the embodiment shown, the working area includes a loading and unloading area and a first cutting area that are arranged opposite each other (at a 180° angle). The first edge skin bearing device 111 includes two first edge skin bearing components 1111 that are arranged opposite each other (at a 180° angle). The two first edge skin bearing components 1111 are switched between the loading and unloading area and the first cutting area by a conversion mechanism 1112.

[0039] Regarding the first edge skin support assembly, the first edge skin support assembly may include one or more first edge skin support units, each of which can be used to support at least one edge skin rod. For example, in some embodiments, the first edge skin support assembly may include a plurality of first edge skin support units arranged in vertical layers, each of which can be used to support at least one edge skin rod. For example, the edge skin support assembly may include three, four, five, or six first edge skin support units arranged in vertical layers, and each first edge skin support unit may support one, two, or more edge skin rods. Taking the example that each first edge skin support unit can support two edge skin rods, the two edge skin rods are placed side by side on the first edge skin support unit.

[0040] In such Figure 1 and Figure 3 In the embodiment shown, the first edge skin bearing assembly 1111 includes multiple (e.g., three, four, five, or six) first edge skin bearing units arranged in layers along the vertical direction (i.e., the third direction). Each first edge skin bearing unit carries two edge skin rods 100, which are arranged side by side.

[0041] The first edge skin support unit may include a first edge skin support platform. The length of the first edge skin support platform may be related to the length of the edge skin rod, and the width of the first edge skin support platform may be related to the width of the edge skin rod. Taking two edge skin rods placed side by side on the first edge skin support platform as an example, the length of the first edge skin support platform matches the length of the edge skin rod, and the width of the first edge skin support platform matches the sum of the widths of the two edge skin rods.

[0042] To ensure the edge bar is stably placed on the first edge bar support platform, the first edge bar support unit may further include a first edge bar positioning mechanism for positioning the edge bar supported on the first edge bar support platform. Thus, when the first cutting device performs arc-top cutting on the edge bar supported on the first edge bar support platform, the first edge bar positioning mechanism can position the edge bar to prevent relative displacement between the edge bar and the first edge bar support platform, or relative displacement between the cut arc-top and the edge bar, during the arc-top cutting operation, which would affect the cutting quality. In some embodiments, the first edge positioning mechanism may be, for example, an edge clamping mechanism. For an edge bar, the edge clamping mechanism may include two jaws or clamping blocks arranged along the width direction of the edge bar and a drive source for driving the jaws or clamping blocks. When in use, the placed edge bar is located in the placement space between the two jaws or clamping blocks. The drive source drives the two jaws or clamping blocks to move or actuate towards each other along the width direction of the edge bar, thereby clamping the edge bar located therebetween. Alternatively, for two side strips arranged side-by-side, the first side strip positioning mechanism may include a support, two grippers or blocks, and a drive source for driving the grippers or blocks. The support is centrally located, and the two grippers or blocks are positioned on opposite sides of the support along the width of the side strip. In use, the two side strips are placed within two spaces formed by the support and the two grippers or blocks on either side. The drive source drives the two grippers or blocks to move or actuate towards each other along the width of the side strip to engage with the central support, thus clamping the two side strips. In some embodiments, the first side strip positioning mechanism may be, for example, a side strip clamping mechanism. For a single side strip, the clamping mechanism may include a top clamping block and a drive source for driving the top clamping block. In use, the side strip is placed on the first side strip support platform, and the drive source drives the top clamping block to descend along a third direction, clamping the side strip below it.

[0043] In some embodiments, the first edge bar support platform may be equipped with a suction cup for adsorbing the bottom surface of the edge bar after it has been placed.

[0044] The first cutting device is used to perform an arc-top cutting operation on the edge bar carried by the first edge bar bearing device to remove the arc-top of the edge bar.

[0045] 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 edge skin bearing unit in the first edge skin bearing assembly of the first edge skin bearing device, so as to perform arc-top cutting operation on the edge skin bar carried by the first edge skin bearing unit.

[0046] Generally, the first cutting device also includes a cutting base for mounting the first cutting installation structure and the first cutting unit. The cutting base serves as the main component of the first cutting device. In some examples, the cutting base is relatively large in size and weight to provide a large mounting surface and robust overall stability. It should be understood that the cutting base can serve as a seat for different structures or components performing processing operations within the first cutting device, and the specific structure of the cutting base can be modified based on different functional or structural requirements. In some examples, the cutting base includes fixing or limiting structures such as bases, rods, columns, and frames for supporting different components in the silicon rod cutting and grinding integrated machine. Furthermore, in some examples, the cutting base can be an integral base; in other examples, the cutting base can include multiple independent bases.

[0047] The first cutting mounting structure is disposed on the cutting machine base and corresponds to the first cutting area. In such a case... 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 other structures.

[0048] As mentioned earlier, in Figure 1 and Figure 3 In this embodiment, the first edge skin bearing assembly 1111 includes a plurality of first edge skin bearing units arranged in layers along the vertical direction, each of which can bear at least one edge skin rod 100. Correspondingly, the first cutting device includes a plurality of first cutting units 1132 arranged in layers along the vertical direction and corresponding to the plurality of first edge skin bearing units in the first edge skin bearing assembly 1111.

[0049] The first cutting unit includes: a plurality of first cutting wheels and a first cutting line. In such a case... Figure 1 and Figure 3 In the embodiment shown, the first cutting unit 1132 includes a plurality of first cutting wheels 1133 and a first cutting line 1134, wherein the first cutting line 1134 is wound around the plurality of first cutting wheels 1133 to form at least one first cutting line saw 1135.

[0050] The first cutting wheel 1133 is provided with at least one cutting groove for winding the first cutting line 1134. The cutting groove can define the position of the first cutting line to control the cutting accuracy. Any first cutting wire saw 1135 is formed by winding the first cutting line 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.

[0051] In such Figure 1 and Figure 3 In the embodiment shown, at least one first cutting wire saw 1135 is located in the first direction. 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 the horizontal plane formed by the first direction and the second direction.

[0052] like Figure 1 and Figure 3 As shown, for example, in some embodiments, the first cutting assembly includes multiple first cutting units, and any first cutting unit 1132 includes multiple first cutting wheels 1133, such as four first cutting wheels 1133: first cutting wheel 1133a, first cutting wheel 1133b, first cutting wheel 1133c, and 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 (e.g., rectangle, trapezoid, etc.). Among them, the first cutting wheels 1133a and first cutting wheels 1133b are in front (relatively closer to the loading and unloading). The first cutting wheel 1133c and the first cutting wheel 1133d are arranged in parallel left and right directions along the first direction. The first cutting line 1134 is arranged after 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). The at least one first cutting wire saw 1135 is arranged along the first direction. In addition, in order for the at least one first cutting wire saw 1135 to effectively cut the edge bar 100 to be cut, the at least one first cutting wire saw 1135 must interfere with the edge 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 bar 100 to be cut in the third direction.

[0053] In some embodiments, the first cutting line is wound around each of the first cutting wheels in an end-to-end manner to form a loop cutting line (also known as a closed-loop cutting line). In such... Figure 1 and Figure 3 In the embodiment shown, the first cutting line 1134 is wound around the four first cutting wheels 1133 in a way that the ends are connected to form a ring cutting line (also known as a closed-loop cutting line).

[0054] In the first cutting unit, multiple first cutting wheels are wound around a circular cutting wire. In this example, the arc-top cutting device can eliminate the need for a wire storage spool. The circular cutting wire is driven by a cutting wire drive device to maintain high-speed operation. Furthermore, the circular cutting wire can run in the same direction during the cutting operation (unlike traditional non-circular cutting wires with wire storage spools, which alternate between forward and reverse rotation). Thus, the arc-top cutting device can achieve high-precision cutting operations, avoiding problems such as wavy cut surfaces caused by changes in cutting wire direction or speed in existing cutting methods. Simultaneously, the circular cutting wire effectively reduces the total length of the cutting wire required for the arc-top cutting device, lowering production costs.

[0055] In some embodiments, the cutting wire drive device is a motor with a power output shaft connected to a first cutting wheel, so that the first cutting wire can be driven by the first cutting wheel to run along the winding direction. Of course, in specific implementations, the cutting wire drive device can also be other drive sources such as a hydraulic motor, as long as it can drive the cutting wire to run, and this application does not impose any restrictions.

[0056] The first cutting component in this application may further include a first transition wheel, which is used to reverse or guide the first cutting line, or the first transition wheel can be used to adjust the tension of the first cutting line. The number of the first transition wheels may be one or more, depending on the layout requirements.

[0057] The first transition wheel, while guiding and tractioning the first cutting wire, also serves as a tensioning wheel for adjusting the tension of the first cutting wire. The tensioning wheel is used to adjust the tension of the first cutting wire, which can reduce the probability of wire breakage and thus reduce material consumption.

[0058] like Figure 1 and Figure 3As shown, for example, in some embodiments, the first cutting assembly includes multiple first cutting wheels and multiple first transition wheels, such as first cutting wheel 1133a, first cutting wheel 1133b, first transition wheel 1136a, and first transition wheel 1136b. The surfaces of the first cutting wheel 1133a, first cutting wheel 1133b, first transition wheel 1136a, and first transition wheel 1136b are all located in a horizontal plane and form a quadrilateral (e.g., rectangle, trapezoid, etc.). The first cutting wheel 1133a and first cutting wheel 1133b are in front (relatively closer to the front). The first cutting wheel 1133a and the first transition wheel 1136b are arranged in parallel left and right directions (near the loading and unloading area). The first cutting line 1134 is arranged in parallel left and right directions after 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). The at least one first cutting wire saw 1135 is arranged along the first direction. In addition, in order for the at least one first cutting wire saw 1135 to effectively cut the edge bar 100 to be cut, the at least one first cutting wire saw 1135 must interfere with the edge 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 bar 100 to be cut in the third direction.

[0059] As previously described, the first cutting line is wound around a plurality of first cutting wheels or a plurality of first cutting wheels and a plurality of first transition wheels to form a first cutting wire saw 1135 between the first cutting wheels (e.g., between the first cutting wheel 1133a and the first cutting wheel 1133b). Therefore, to adjust the line length of the first cutting wire saw 1135, it can be achieved by adjusting the spacing between the first cutting wheels 1133a and the first cutting wheels 1133b. This can be achieved by changing the position of at least one of the first cutting wheels 1133a and the first cutting wheel 1133b.

[0060] Furthermore, the first wire saw can still have other variations, such as... Figure 1 and Figure 3In the illustrated embodiment, the first cutting wheel 1133a and the second cutting wheel 1133b are arranged in parallel along the first direction. The first cutting line 1134 is wound around multiple first cutting wheels 1133 or multiple first cutting wheels 1133 and multiple first transition wheels 1136 to form a first cutting wire saw 1135 between the first cutting wheels 1133 (e.g., between the first cutting wheels 1133a and the first cutting wheels 1133b). The first cutting wire saw 1135 is arranged along the first direction, but is not limited thereto. In other embodiments, the position of the first cutting wire saw 1135 may be located in a horizontal plane and arranged at a first directional angle with respect to the first direction. The horizontal plane is composed of the first direction and the second direction. The first directional angle is less than or equal to 45° (≤±45°). That is, the cutting direction of the first cutting wire saw 1135 may be located in the same horizontal plane as the first direction and form an angle of 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 wheels 1133a and 1133b is in front and the other is behind. For example, the first cutting wheel 1133a is in front and the first cutting wheel 1133b is behind (the angle formed by the first cutting wire saw formed by the first cutting wheel 1133a in front and the first cutting wheel 1133b behind and the first cutting wheel 1133b behind can be called the positive angle) or the first cutting wheel 1133b is in front and the first cutting wheel 1133a is behind (the angle formed by the first cutting wheel 1133a in front and the first cutting wheel 1133b behind and the first cutting wheel 1133b behind can be called the positive angle). The angle formed by the first cutting wire saw 1133b in front and the first direction is called the negative angle. Thus, when cutting the arc top, the leading portion of the first cutting wire saw 1135 enters the edge bar 100 first, and during the advancement process, the trailing portion of the first cutting wire saw 1135 enters the edge bar 100 later, continuously cutting the edge bar 100. Finally, the leading portion of the first cutting wire saw 1135 exits the edge bar 100 first, followed by the trailing portion, until the arc top of the edge bar 100 is removed. The first direction angle can be changed according to the cutting process requirements and the size specifications of the edge bar to be cut. For example, the angle can be adjusted by changing the position of one or both of the first cutting wheels 1133a and 1133b associated with the first cutting wire saw 1135.

[0061] In some embodiments, the first cutting assembly also includes a tension adjustment mechanism. In wire EDM, the tension of the cutting wire affects the yield and processing accuracy. The tension adjustment mechanism detects and adjusts the tension so that the tension of the cutting wire reaches a certain set threshold and remains at a constant value or within a certain range allowed by the constant value as the numerical center during cutting.

[0062] In some embodiments, the tension adjustment mechanism is associated with a transition wheel, which in the wire cutting unit serves as a tensioning wheel for adjusting the tension of the cutting wire while simultaneously guiding and pulling the cutting wire.

[0063] Tensioners are used to adjust the tension of the cutting wire, reducing the probability of wire breakage and thus reducing material consumption. The cutting wire plays a crucial role in cutting operations, but even the best wire has limitations in elongation and wear resistance. This means that the wire gradually thins during continuous operation until it eventually breaks. Therefore, modern wire EDM equipment generally incorporates a wire tension compensation mechanism to compensate for the wire's elongation during its reciprocating motion; the tensioner is one such mechanism.

[0064] For example, in some embodiments, the tension adjusting mechanism can detect tension and adjust the tension based on the detection result. The method of tension adjustment is not limited; for example, it can be achieved by adjusting the first transition wheel. In some cases, when the detected tension is below the set requirement, the position of at least one of the two first transition wheels is adjusted, for example, by moving the first transition wheel outward to increase the circumference enclosed by the first cutting wheels and the first transition wheels, thereby increasing the tension. In some cases, when the detected tension exceeds the set requirement, the position of at least one of the two first transition wheels is adjusted, for example, by moving the first transition wheel inward to decrease the circumference enclosed by the first cutting wheels and the first transition wheels, thereby decreasing the tension.

[0065] In some embodiments, the first cutting assembly may further include: at least one first adjusting mechanism for driving the plurality of first cutting wheels to move relative to the first cutting mounting structure in a direction perpendicular to the wheel surface.

[0066] The first cutting assembly can switch the first cutting line between different cutting slots of the first cutting wheel based on the first adjusting mechanism, or adjust the position of the first cutting wire saw (e.g., in a third direction) to change the cutting position (or processing specifications) relative to the silicon rod. In practical applications, the first adjusting mechanism may include, for example: a lead screw, arranged in the orthogonal direction of the first cutting wheel surface and threadedly connected to the first cutting wheel; a drive source for driving the lead screw to rotate. Alternatively, the first adjusting mechanism may include, for example: a telescopic member, arranged in the orthogonal direction of the first cutting wheel surface and associated with the first cutting wheel; a drive source for driving the telescopic member to extend or retract in the orthogonal direction of the first cutting wheel surface. Alternatively, the first adjusting mechanism may include, for example: a rack, arranged in the orthogonal direction of the first cutting wheel surface on the first cutting wheel; a transmission gear, meshing with the rack; a drive source for driving the transmission gear to rotate.

[0067] In some implementations, the first cutting device is a movable cutting device; therefore, the first cutting device further includes a cutting mounting structure drive mechanism for driving the first cutting mounting structure and its plurality of first cutting units to move relative to the first edge support device. Figure 1 and Figure 3 In the embodiment shown, the first cutting device 113 further includes a cutting mounting structure driving mechanism 1137 for driving the first cutting mounting structure 1131 and its plurality of first cutting units 1132 to move along the second direction.

[0068] In some embodiments, the cutting and mounting structure driving mechanism includes a moving guide rail and a moving drive unit. The moving guide rail is arranged along a second direction and is used to mount the first cutting and mounting structure. The moving drive unit is used to drive the first cutting and mounting structure and at least one first cutting unit thereon to move along the moving guide rail.

[0069] In some embodiments, the moving drive unit includes a moving gear, a drive gear, and a drive source. The moving gear is arranged along a second direction and parallel to the moving guide rail. The drive gear is disposed on the first cutting mounting structure and meshes with the moving gear, driving the first cutting mounting structure to move along the moving guide rail. The drive gear is driven to rotate by the drive source, and its teeth mesh with the moving gear, traveling in accordance with the moving gear. The first cutting mounting structure connected to the drive gear thus moves accordingly on the moving guide rail. The drive source is, for example, a drive motor.

[0070] In some embodiments, the moving drive unit may be disposed on the first cutting mounting structure, including a moving lead screw and a drive source, wherein the moving lead screw is disposed along a second direction and associated with the first cutting mounting structure, and the drive source is used to drive the moving lead screw to rotate so that the associated first cutting mounting structure and at least one first cutting unit thereon move along the moving guide rail. The drive source is, for example, a drive motor.

[0071] When performing arc-top cutting on the edge bar using the arc-top cutting equipment, the first cutting line is driven by the cutting line drive device to run along the winding direction, and the first cutting installation structure and at least one first cutting unit thereon are driven by the cutting installation structure drive mechanism to move along the second direction so as to achieve relative feeding with the edge bar carried by the at least one first edge bar support unit in the first edge bar support device so that the arc-top of the edge bar is cut off by the first cutting line saw, forming an arc-top surface (in the following description, the arc-top surface may be referred to as the top surface) on the edge bar, and the top surface may be parallel or substantially parallel to the bottom surface.

[0072] In this application, the arc-top cutting equipment also includes an edge-skin loading and unloading device for loading the edge-skin bar to be cut onto the first edge-skin carrying device and unloading the edge-skin bar with the arc-top cut off from the first edge-skin carrying device. Furthermore, in practical applications, the edge-skin loading and unloading device may also include unloading the remaining arc-top material to be cut off from the first edge-skin carrying device.

[0073] In some embodiments, the side panel loading and unloading device may include: a reversing vehicle and a gripping unit disposed on the reversing vehicle. In such... Figure 1 and Figure 3 In the embodiment shown, the arc top cutting device 11 further includes a side skin loading and unloading device 115, which may include a reversing carrier 1151 and a gripping unit 1153 disposed on the reversing carrier 1151.

[0074] The reversing carrier is driven to perform a reversing motion, thereby causing the gripping unit on it 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 bars to be processed, for example, in the feeding area, the edge bars are transported to the feeding area by a conveyor belt, and the unloading area is used for unloading the edge bars with the cut-off arc top and the remaining material with the cut-off arc top. 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 is set at 90° to the loading and unloading area, and the loading and unloading area is set at 90° to the unloading area. In some embodiments, the working area may include: a feeding area, a loading and unloading area, a side bar unloading area, and an arc-top unloading area. These working areas are arranged at certain angles. For example, the feeding area, loading and unloading area, side bar unloading area, and arc-top unloading area are arranged at 90° angles to each other in pairs. For details, please refer to [link to relevant documentation]. Figure 1 and Figure 3 As shown.

[0075] The reversing vehicle is driven to perform a reversing motion to switch between different work areas. In such cases... Figure 1 and Figure 3 In the illustrated embodiment, the feeding area, loading / unloading area, side bar unloading area, and arc-top unloading area in the working area are arranged in pairs at 90° intervals, clockwise (or counterclockwise), with the reversing carrier located in the center of each working area. Assuming the reversing carrier currently corresponds to the feeding area, if it is driven to rotate 90° clockwise, it then corresponds to the loading area. Assuming the reversing carrier currently corresponds to the loading / unloading area, if it is driven to rotate 180° clockwise or counterclockwise, it then corresponds to the arc-top unloading area. In some embodiments, the reversing carrier can achieve reversing motion via a carrier rotation mechanism, which may include a rotating shaft and a rotating motor.

[0076] The gripping unit is mounted on the reversing carrier and is used to grip objects in each work area. The gripping unit moves between work areas following the reversing motion of the reversing carrier. For example, before the arc-top cutting operation, the gripping unit grips the edge bar to be processed; after the arc-top cutting operation is completed, the gripping unit grips the remaining material at the arc-top and the edge bar with the arc-top cut off. In some embodiments, the gripping unit may be, for example, a vacuum suction cup. In some embodiments, the gripping unit may be, for example, a clamp.

[0077] As previously described, in some embodiments, the first edge-supporting assembly may include a plurality of first edge-supporting units arranged in layers along the vertical direction. Correspondingly, the gripping unit can be movably mounted on the reversing vehicle via a lifting mechanism. Using the lifting mechanism, the gripping unit can move up and down relative to the reversing vehicle to adapt to the various first-supporting units arranged in layers. In some embodiments, the lifting mechanism may include a lifting guide rail and a lifting drive unit, the lifting guide rail being arranged on the reversing vehicle along the lifting direction. In some embodiments, the lifting drive unit may include a lifting rack, a drive gear, and a drive source, wherein the lifting rack is arranged on the reversing vehicle along the lifting direction and parallel to the lifting guide rail, the drive gear meshes with the lifting rack and is associated with the gripping unit, and the drive source is associated with the drive gear for driving the drive gear to rotate. In some embodiments, the lifting drive unit may include a lifting screw and a drive source, wherein the lifting screw is arranged along the lifting direction and associated with the gripping unit, and the drive source is used to drive the lifting screw to rotate so that the lifting guide rail of the associated gripping unit moves. In some examples, the drive source may be, for example, a drive motor.

[0078] by Figure 1 and Figure 3Taking the arc-top cutting device in the illustrated embodiment as an example, during the arc-top cutting operation, the gripping unit 1153 in the edge-top loading and unloading device 115 grips the edge-top bar 100 to be processed located in the feeding area. For example, the gripping unit 1153 can grip two edge-top bars 100 at a time. After driving the reversing carrier 1151 in the edge-top loading and unloading device 115 to rotate (for example, rotate 90° clockwise), it turns from facing the feeding area to facing the loading and unloading area. The gripping unit 1153 places the gripped edge-top bar 100 to be processed onto the first edge-top support platform of the first edge-top support assembly 1111 in the first edge-top support device 111 located in the loading area. When 11 includes multiple first edge-supporting units arranged vertically in layers, the edge-supporting loading and unloading device 115 needs to perform multiple loading operations to grab the edge-supporting bars 100 to be processed from the feeding area and transfer them to the loading and unloading area to place the edge-supporting bars 100 on the first edge-supporting platform of the corresponding first edge-supporting unit. During the loading operation, the grabbing unit 1153 in the edge-supporting loading and unloading device 115 also needs to move up and down relative to the steering carrier 1151 through the lifting mechanism to adapt to the different first edge-supporting units arranged in layers. After all the first edge-supporting units (or according to a set number) in the first edge-supporting assembly 1111 in the loading and unloading area have completed the loading of the edge-supporting bars 100, the first edge-supporting unit is used to load the edge-supporting bars 100. The conversion mechanism 1112 in device 111 performs a conversion, driving the first edge skin support assembly 1111 located in the loading and unloading area to switch to the first cutting area, and driving the first edge skin support assembly 1111 located in the first cutting area to switch to the loading and unloading area; the cutting wire drive device drives the first cutting wire 1134 to run along the winding direction, and the cutting mounting structure drive mechanism 1137 drives the first cutting mounting structure 1131 and its plurality of first cutting units 1132 to move along the second direction so that the first cutting wire saw 1135 in the plurality of first cutting units 1132 and the edge skin bar 100 carried by the plurality of first edge skin support units in the first edge skin support assembly 1111 located in the first cutting area are in contact. For the feed, the first cutting wire saw 1135 cuts off the arc top of the edge bar 100. Correspondingly, the edge bar loading and unloading device 115 continues to load the edge bar 100 to be processed onto each of the first edge bar carrying units in the first edge bar carrying assembly 1111 located in the loading area. After the edge bar 100 carried by the multiple first edge bar carrying units in the first edge bar carrying assembly 1111 located in the first cutting area completes the arc top cutting operation, the conversion mechanism 1112 in the first edge bar carrying device 111 is used to convert the first edge bar carrying assembly 1111 located in the first cutting area to the loading and unloading area and the first edge bar carrying assembly 1111 located in the loading and unloading area to the first cutting area.For the first edge skin bearing assembly 1111 that is converted to the loading area, the edge skin loading and unloading device 115 sequentially transfers the cut-off arc top material 101 on each of the first edge skin bearing units in the first edge skin bearing assembly 111 to the arc top unloading area. Then, the edge skin loading and unloading device 115 sequentially transfers the edge skin rods 102 with the cut-off arc top on each of the first edge skin bearing units in the first edge skin bearing assembly 1111 to the edge skin rod unloading area. For the first edge skin bearing assembly 1111 that is converted to the first cutting area, the cutting mounting structure driving mechanism 1137 drives the first cutting mounting structure 1131 and its plurality of first cutting units 1132 to move along the second direction so that the first cutting wire saw 1135 in the plurality of first cutting units 1132 and the edge skin rods 100 carried by the corresponding plurality of first edge skin bearing units in the first edge skin bearing assembly 1111 in the first cutting area achieve relative feeding, and the arc top of the edge skin rod 100 is cut off by the first cutting wire saw 1135. The unloading operation, in which the edge-feeding device 115 sequentially transfers the cut-off arc-top remnants 101 from each of the first edge-feeding units in the first edge-feeding assembly 1111 to the arc-top unloading area, is similar to the unloading operation, in which the edge-feeding device 115 sequentially transfers the edge-feeding rods 102 with their arc-tops cut off from each of the first edge-feeding units in the first edge-feeding assembly 1111 to the edge-feeding rod unloading area. For example, in the case of the edge-feeding device 115 sequentially transferring the edge-feeding rods 102 with their arc-tops cut off from each of the first edge-feeding units in the first edge-feeding assembly 1111 to the edge-feeding rod unloading area, the gripping unit 1153 in the edge-feeding device 115 grips the edge-feeding rod 102 with its arc-top cut off from a certain first edge-feeding unit in the loading and unloading area, driving the reversing carrier 1151 in the edge-feeding device 115. After rotating (e.g., 90° clockwise), the edge bar 102 is moved from the loading / unloading area to the edge bar unloading area. The gripping unit 1153 then places the gripped edge bar 102 with its cut-off arc top into the edge bar unloading area (or, for example, the conveyor belt located in the edge bar unloading area). When the first edge bar carrying assembly 1111 of the first edge bar carrying device 111 includes multiple first edge bar carrying units arranged vertically in layers, the edge bar loading / unloading device 115 needs to perform multiple unloading operations: gripping the edge bar 102 with its cut-off arc top from the loading / unloading area and transferring it to the edge bar unloading area to place the edge bar 102 in the edge bar unloading area. During the unloading operation, the gripping unit 1153 in the edge bar loading / unloading device 115 also needs to move up and down relative to the steering carrier 1151 via a lifting mechanism to adapt to the different first edge bar carrying units arranged in layers.

[0079] The stacking device in this application is used to stack multiple edge bars to form an edge bar stack, wherein the edge bar refers to the edge bar with the arc top cut off after the arc top is cut off by the arc top cutting device.

[0080] The stacking of multiple edge strips specifically involves bonding them together with their surfaces in contact. To ensure the strength of the bonding between the edge strips and to ensure that each edge strip meets the requirements of the production process, in some implementations, a grinding device is included between the arc-top cutting device and the stacking device to grind the edge strips with the arc-top cut off output by the arc-top cutting device. Figure 1 In the embodiment shown, a grinding device 12 is also included between the arc-top cutting device 11 and the stacking device 13.

[0081] In some embodiments, the grinding operation on the edge bar with the arc-shaped top removed includes grinding the bottom surface of the edge bar with the arc-shaped top removed. In some embodiments, the grinding operation on the edge bar with the arc-shaped top removed includes grinding both the bottom and top surfaces of the edge bar with the arc-shaped top removed. In some embodiments, the grinding operation on the edge bar with the arc-shaped top removed includes grinding the top surface of the edge bar with the arc-shaped top removed. In this embodiment, the edge bar is cut with an arc-shaped top cutting device, wherein the first cutting device in the arc-shaped top cutting device adopts a circular cutting line. The circular cutting line can achieve high-precision cutting, so that the flatness of the top surface of the edge bar after the arc-shaped top is removed meets the production process requirements. Therefore, in this embodiment, the grinding device is used to grind the bottom surface of the edge bar with the arc-shaped top removed output by the arc-shaped top cutting device.

[0082] In this application, as Figure 1In the illustrated embodiment, an edge-faced and conveying device 14 is further included between the arc-top cutting device 11 and the grinding device 12. The edge-faced and conveying device 14 is located in the turning and conveying area between the arc-top cutting device 11 and the grinding device 12, and is used to turn the edge-faced bar with the arc-top cut off and convey it to the grinding device 12. In this embodiment, the edge-faced bar with the arc-top cut off output by the arc-top cutting device is placed in the edge-faced bar unloading area (or, for example, the conveyor belt located in the edge-faced bar unloading area) with the bottom surface facing down and the top surface facing up. Since the grinding device performs grinding operations on the bottom surface of the edge-faced bar with the arc-top cut off, it is also necessary to turn the edge-faced bar with the arc-top cut off so that it is placed with the bottom surface facing up and the top surface facing down. Of course, the above is merely an illustrative example and is not intended to be limiting. For instance, in some embodiments, the edge bar can be flipped during the transfer of the edge bar with its cut-off arc top from the loading / unloading area to the edge bar unloading area using the edge bar loading / unloading device in the arc top cutting equipment, thus eliminating the need for the aforementioned edge bar flipping and conveying equipment to flip the edge bar. Alternatively, in some embodiments, the grinding equipment can perform the grinding operation on the edge bar with its cut-off arc top placed with its bottom surface facing down and its top surface facing up, thus eliminating the need for the aforementioned edge bar flipping and conveying equipment to flip the edge bar.

[0083] In some embodiments, the edge-faced and conveying equipment may further include edge-faced conveying equipment and edge-faced turning equipment. See also... Figure 4 Displayed as Figure 1 A schematic diagram of the structure of the edge-turning and conveying equipment. (In such cases...) Figure 1 and Figure 4 In the illustrated embodiment, 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 bar with the cut-off arc top from the edge skin bar feeding area to the edge skin turning device, and the edge skin turning device is used to turn the edge skin bar with the cut-off arc top over. As mentioned above, in some embodiments, when it is not necessary to turn the edge skin bar with the cut-off arc top over, the edge skin turning device can be omitted.

[0084] The edge conveying device may be, for example, a conveyor belt or a conveyor chain.

[0085] The edge-turning equipment may include an edge-turning device, an edge-bar loading device, and an edge-bar conveying device.

[0086] The edge-facer device is used to flip edge-facer bars with the cut-off arc top. In some embodiments, the edge-facer device includes a flipping mechanism and at least one edge-facer clamp disposed on the flipping mechanism, the at least one edge-facer clamp being used to hold the edge-facer bar with the cut-off arc top. In some embodiments, the flipping mechanism may include a rotating shaft and a rotating motor, the rotating shaft being horizontally arranged.

[0087] The edge leather clamp is mounted on the flipping mechanism and is used to clamp the edge leather bar with the cut-off arc top. The edge leather clamp flips as the flipping mechanism rotates. For example, in the initial state, the edge leather clamp is located on one side of the flipping mechanism and is in a horizontal position. The edge leather bar with the cut-off arc top is transported over and placed in the clamping space of the edge leather furniture. At this time, the edge leather bar with the cut-off arc top is placed with the bottom surface down and the top surface up. Subsequently, the flipping mechanism is driven to rotate (e.g., rotate 180° clockwise or counterclockwise) to change the edge leather furniture from being located on one side of the flipping mechanism and in a horizontal position to being located on the other side of the flipping mechanism and in a horizontal position. At this time, the edge leather bar with the cut-off arc top is placed with the bottom surface up and the top surface down.

[0088] The edge bar loading device is used to load edge bars with the cut-off arc apex onto the edge bar clamp. In some embodiments, the edge bar loading device includes a gripping unit. In some embodiments, the gripping unit may be, for example, a vacuum suction cup. In some embodiments, the gripping unit may be, for example, a clamp. Furthermore, in some embodiments, the edge bar loading device, in addition to the gripping unit, also includes a gripping unit moving mechanism for driving the gripping unit to move.

[0089] The edge conveying device is used to convey edge bars with the cut-off arc top. In some embodiments, edge conveying devices are respectively arranged on opposite sides of the edge turning device. One edge conveying device is used to convey unturned edge bars (bottom side down, top side up) to the edge clamp of the edge turning device, and the other edge conveying device is used to convey turned edge bars (bottom side up, top side down) from the edge clamp to the grinding equipment. In some embodiments, the edge conveying device may be, for example, a conveyor belt.

[0090] After the edge bar with the cut-off arc top is flipped using the edge bar flipping and conveying equipment, the bottom surface of the edge bar with the cut-off arc top can be ground using the grinding equipment.

[0091] In some embodiments, the grinding equipment may include a second edge-skin support device and a grinding device, wherein the second edge-skin support device is used to support an edge-skin bar with its arc-shaped top cut off, and the grinding device is used to perform grinding operations on the bottom surface of the edge-skin bar with its arc-shaped top cut off, supported by the second edge-skin support device. In some embodiments, the grinding equipment further includes a grinding machine base, on which the second edge-skin support device and the grinding device are mounted. Please refer to [link to relevant documentation]. Figure 5 Displayed as Figure 1 A schematic diagram of a medium-speed grinding mill. (In such cases...) Figure 1 and Figure 5 In the illustrated embodiment, the grinding equipment 12 may include a grinding machine base 121 and a second edge bearing device 123 and a grinding device 125 disposed on the grinding machine base 121.

[0092] In some embodiments, the second edge-carrying device is a movable edge-carrying device, and the grinding device is a fixed grinding device. Driving the second edge-carrying device allows the second edge-carrying device to move closer to or further away from the grinding device.

[0093] In some embodiments, the second edge skin support device is a fixed edge skin support device, and the grinding device is a movable grinding device. The grinding device is driven so that it can move closer to or further away from the second edge skin support device.

[0094] In some embodiments, the second edge skin support device is a movable edge skin support device, and the grinding device is a movable grinding device. Driving the second edge skin support device and / or the grinding device can cause the second edge skin support device and the grinding device to move closer to or further away from each other.

[0095] The second edge skin bearing device may include a second edge skin bearing platform, which can be used to bear at least one edge skin bar with its arc-shaped tip cut off. Taking one edge skin bar with its arc-shaped tip cut off as an example, the length of the second edge skin bearing platform may be related to the length of the edge skin bar with its arc-shaped tip cut off, and the width of the second edge skin bearing platform may be related to the width of the edge skin bar with its arc-shaped tip cut off. Taking two edge skin bars with their arc-shaped tips cut off, placed side-by-side on the second edge skin bearing platform, the length of the second edge skin bearing platform matches the length of the edge skin bar with its arc-shaped tip cut off, and the width of the second edge skin bearing platform matches the sum of the widths of the two edge skin bars with their arc-shaped tips cut off.

[0096] To ensure the edge bar with its arc-cut top is securely placed on the second edge bar support platform, the second edge bar support device may further include a second edge bar positioning mechanism for positioning the edge bar supported on the second edge bar support platform. Thus, when the edge bar supported on the second edge bar support platform is ground using a grinding device, the second edge bar positioning mechanism can position the edge bar to prevent relative displacement between the edge bar and the second edge bar support platform during grinding, thus avoiding any impact on grinding quality. In some embodiments, the second edge bar positioning mechanism may be, for example, a suction cup provided on the second edge bar support platform, used to adhere to the top surface of the edge bar after it has been placed on the second edge bar support platform. In some embodiments, the second edge-skin positioning mechanism may be, for example, a limiting groove provided on the second edge-skin support platform, used to limit the top surface and the side surface adjacent to the top surface of the edge-skin bar after the cut-off arc top has been placed on the second edge-skin support platform. The limiting groove may be, for example, a V-groove. In some embodiments, the second edge-skin positioning mechanism may be, for example, an edge-skin clamping mechanism, used to clamp the edge-skin bar located therebetween.

[0097] In some embodiments, the second edge skin support device is a fixed edge skin support device, which is fixed to the grinding machine base.

[0098] In some embodiments, the second edge skin support device is a movable edge skin support device, and the second edge skin support device further includes a second support platform moving mechanism for driving the second edge skin support platform to move.

[0099] In some embodiments, the second carrier platform moving mechanism may include: a moving guide rail, a moving slider, and a moving drive unit, wherein the moving guide rail is along the moving direction (e.g., Figure 1 The X-axis is set on the grinding machine base, and the movable slider is set on the second side bearing platform.

[0100] In some embodiments, the moving drive unit may include a moving rack, a drive gear, and a drive source, wherein the moving rack is disposed on the grinding machine base along the moving direction and parallel to the moving guide rail, the drive gear meshes with the moving rack and is associated with the second edge support platform, and the drive source is associated with the drive gear for driving the drive gear to rotate. In some examples, the drive source may be, for example, a drive motor.

[0101] In some embodiments, the motion drive unit may include a movable lead screw and a drive source, wherein the movable lead screw is disposed along a first direction and associated with the second side skin support platform, and the drive source is used to drive the movable lead screw to rotate so that the associated second side skin support platform moves along the movable guide rail. The drive source is, for example, a drive motor.

[0102] As mentioned above, in some embodiments, the grinding device is a fixed grinding device, which includes: a grinding frame, a grinding support, and at least one surface grinding wheel. The grinding frame is fixedly mounted on the grinding machine base, the grinding support is movably mounted on the grinding frame in the vertical direction, and the at least one surface grinding wheel is mounted on the grinding support for grinding the bottom surface of the edge bar with the cut-off arc top carried by the second edge bearing device.

[0103] The grinding support is movably mounted on the grinding frame via a support lifting mechanism.

[0110] At least one surface grinding wheel is mounted on the grinding support and is used to grind the bottom surface of the edge bar with the cut-off arc top. The surface of the at least one surface grinding wheel is horizontal.

[0111] Furthermore, in some embodiments, both fixed and mobile grinding devices may include a grinding wheel advance / retract mechanism for driving the at least one surface grinding wheel to move along the grinding advance / retract direction relative to the grinding machine base, the grinding advance / retract direction being perpendicular to the grinding direction.

Taking a suction cup handling robot as an example, the suction cup handling robot is flexible and can move up and down, translate left and right, move forward and backward, and rotate. It can pick up edge bars with the cut-off arc tops from the edge turning and conveying device and transfer them to the second edge carrying device of the grinding equipment, and unload ground edge bars with the cut-off arc tops from the second edge carrying device.

[0114] by Figure 1 and Figure 5Taking the grinding equipment in the illustrated embodiment as an example, when performing the bottom surface grinding operation of the edge bar 102 with the arc top removed, the edge bar 102 with the arc top removed is picked up by the edge bar loading and unloading device and placed on the second edge bar support platform of the second edge bar support device 123. At this time, the edge bar 102 with the arc top removed is output after being flipped by the edge bar flipping and conveying device. Therefore, the edge bar 102 with the arc top removed is placed on the second edge bar support platform of the second edge bar support device 123 with the bottom surface on top and the top surface on the bottom. In addition, the edge bar with the arc top removed can be positioned by the second edge bar positioning mechanism; the surface grinding wheel in the grinding device 125 is driven to rotate, driving the second edge bar 102 to rotate.

[0116] In addition, in practical applications, the edge bar cleaning equipment also includes an edge bar turning device and an edge bar conveying device.

In some embodiments, the turning mechanism may include a rotating shaft and a rotating motor, the rotating shaft being horizontally arranged. The edge-bar clamp is disposed on the turning mechanism and is used to hold the polished edge-bar, wherein the edge-bar clamp turns over as the turning mechanism rotates. For example, in the initial state, the edge leather clamp is located on one side of the flipping mechanism and is in a horizontal position. The polished edge leather bar is transported over and placed in the clamping space of the edge leather furniture. At this time, the polished edge leather bar is placed with the top surface down and the bottom surface up. Subsequently, the flipping mechanism is driven to rotate (e.g., rotate 180° clockwise or counterclockwise) to change the edge leather furniture from being located on one side of the flipping mechanism and in a horizontal position to being located on the other side of the flipping mechanism and in a horizontal position. At this time, the polished edge leather bar is placed with the bottom surface down and the top surface up.

[0118] The edge conveying device is used to convey the ground edge bars. In some embodiments, edge conveying devices are respectively arranged on opposite sides of the edge turning device. One edge conveying device is used to convey unturned edge bars (bottom side up, top side down) to the edge clamp of the edge turning device, and the other edge conveying device is used to convey turned edge bars (bottom side down, top side up) from the edge clamp to the stacking device.

[0122] The edge skin stacking and gluing device is used to sequentially stack and glu multiple edge skin bars with their arc-shaped tops cut off into a stack, forming an edge skin bar stack. In some embodiments, the edge skin stacking and gluing device includes a carrying and conveying unit, a handling unit, and a gluing and pre-pressing unit.

[0123] Please see Figure 7 Displayed as Figure 1 A schematic diagram of the structure of the edge-layer stacking and gluing device. (In...) Figure 1 and Figure 7 In the illustrated embodiment, the stacking device 13 includes a skin stacking and gluing device 131, which further includes a carrying and conveying unit 1311, a handling unit 1313, and a gluing and pre-pressing unit.

[0124] The carrying and conveying unit is used to carry the edge bar with the cut-off arc top and drive the edge bar to move.

[0125] In such Figure 1 and Figure 7 In the embodiment shown, the carrying and conveying unit 1311 includes: a side skin carrying platform 13111, a lifting mechanism 13113, and a conveying mechanism 13115. The lifting mechanism 13113 is used to drive the side skin carrying platform 13111 to move vertically, and the conveying mechanism 13115 is used to drive the side skin bar stack carried by the side skin carrying platform 13111 to move along the conveying direction.

[0126] The lifting mechanism is used to drive the edge skin support platform to move vertically up and down, thereby adjusting the height of the edge skin bar with the cut-off arc top supported by the edge skin support platform. In some embodiments, the lifting mechanism may include a lifting drive source and a lifting rod (support). The number of lifting rods (supports) may be one or more, and these lifting rods (supports) may be located at the bottom of the edge skin support platform. The lifting drive source is used to drive the lifting rods (supports) to move vertically up and down to move the edge skin support platform. The lifting drive source may be, for example, a lifting cylinder or a lifting hydraulic cylinder (or a combination of a lifting screw and a lifting motor). The lifting cylinder or lifting hydraulic cylinder may be located at the bottom of the machine base. One or more lifting rods (supports) are all located on a transition plate. The transition plate rests on the output shaft of the lifting cylinder or lifting hydraulic cylinder, wherein the transition plate is connected to the output shaft of the lifting cylinder or lifting hydraulic cylinder, or the transition plate is pressed onto the output shaft of the lifting cylinder or lifting hydraulic cylinder in a non-connected manner. In some examples, the lifting cylinder or lifting hydraulic cylinder drives the output shaft to extend, pushing the adapter plate and its lifting rod (support) to rise vertically, thereby causing the edge skin support platform and the edge skin rods or edge skin rod stacks it carries to rise vertically. In some examples, the lifting cylinder or lifting hydraulic cylinder drives the output shaft to retract, pulling the adapter plate and its lifting rod (support) to descend vertically, thereby causing the edge skin support platform and the edge skin rods or edge skin rod stacks it carries to descend vertically (or, the adapter plate and its lifting rod (support), the edge skin support platform and the edge skin rods or edge skin rod stacks it carries to descend vertically under the action of gravity).

[0127] The conveying mechanism is used to drive the stack of edge strips carried by the edge strip support platform to move along the conveying direction. In some embodiments, the conveying mechanism includes a roller assembly and a motor assembly for controlling the roller assembly. Figure 7In the illustrated embodiment, a roller assembly is arranged along a first direction, located outside the edge bar support platform, for supporting the edge bar stack. In some embodiments, the roller assembly includes two rows of roller groups arranged side-by-side along the first direction, each row including multiple rollers arranged along the first direction. The axis of each roller is aligned with a second direction, and the roller surface of each roller can form an edge bar support surface, which can be, for example, aligned with a horizontal plane. Furthermore, the distance between the two rows of roller groups is less than the width of the edge bar being supported. Specifically, since the edge bar support platform contacts the bottom surface of the edge bar when supporting the edge bar with its cut-off arc top, the distance between the two rows of roller groups is less than the width of the bottom surface of the edge bar. The motor assembly includes a motor, with each roller pair corresponding to one motor, or multiple roller pairs sharing one motor. The motor drives the corresponding roller to rotate, and the friction between the roller and the edge bar or edge bar stack placed on it drives the edge bar or edge bar stack to be conveyed along a first direction. In practical applications, the lifting mechanism drives the edge bar support platform and the edge bar or edge bar stack it carries to descend vertically until the edge bar support platform is lower than the roller surface of the roller assembly. After that, the edge bar or edge bar stack is transferred from the edge bar support platform to the roller surface of each roller in the roller assembly. Then, the motor assembly drives the associated roller to rotate, and the friction between the roller and the edge bar or edge bar stack placed on it drives the edge bar or edge bar stack to be conveyed along the first direction.

[0128] The transport unit is used to sequentially transport the edge bar with the cut-off arc top to the edge bar bearing and conveying unit.

The drive gear is driven to rotate by the drive source, and its teeth mesh with the moving rack, traveling in accordance with the moving rack. The transport unit connected to the drive gear thus generates corresponding movement on the transport guide rail. The drive source is, for example, a drive motor.

[0131] In some embodiments, the transport drive unit may be mounted on a mounting bracket and includes a transport screw and a drive source. The transport screw is arranged along a first direction and associated with the transport unit, and the drive source is used to drive the transport screw to rotate, thereby moving the associated transport unit along the transport guide rail.

[0132] In some embodiments, the transport drive unit includes a transport chain and a drive source. The transport chain may be a strip-shaped or ring-shaped chain, arranged along a first direction and associated with the transport unit. The drive source drives the transport chain to move, causing the associated transport unit to move along the transport guide rail. The drive source is, for example, a drive motor with a sprocket associated with the transport chain, and the drive motor can drive the sprocket to rotate in both forward and reverse directions. In some examples, the sprocket is always associated with the transport chain; in other examples, the sprocket is movably configured and associated with the transport chain only when the transport unit needs to be driven.

[0139] In some embodiments, the movable drive unit may be mounted on a mounting bracket and includes a movable lead screw and a drive source. The movable lead screw is arranged along a first direction and associated with the adhesive application unit. The drive source is used to drive the movable lead screw to rotate, thereby moving the associated adhesive application unit along the movable guide rail.

[0140] In some embodiments, the mobile drive unit includes a mobile chain and a drive source. The mobile chain may be a strip-shaped or ring-shaped chain, arranged along a first direction and associated with an adhesive application unit. The drive source drives the mobile chain to move the associated adhesive application unit along the mobile guide rail. The drive source is, for example, a drive motor with a drive sprocket associated with the mobile chain. In some examples, the sprocket is always associated with the transport chain; in other examples, the sprocket is movable and associated with the transport chain when the transport unit needs to be driven. In some embodiments, the mobile chain in the mobile drive unit and the transport chain in the aforementioned transport drive unit may be the same chain. In this case, the sprocket in the mobile drive unit is movable, and the sprocket in the transport drive unit is movable. When the transport unit needs to be driven, the sprocket in the transport drive unit is associated with a common chain; when the adhesive application unit needs to be driven, the sprocket in the mobile drive unit is associated with the common chain.

The drive gear is disposed on the preload unit and meshes with the telescopic gear rail, driving the preload unit to move along the telescopic guide rail. The drive gear is driven to rotate by the drive source, and its teeth mesh with the telescopic gear rail, moving in accordance with the telescopic gear rail.

[0146] In some embodiments, the pre-compression unit may be, for example, a pre-compression panel or a pre-compression block.

[0147] In some embodiments, the edge skin stacking and gluing device further includes a centering mechanism for sequentially centering the edge skin bars transported to the edge skin carrying and conveying unit to align the multiple edge skin bars to be stacked. The centering mechanism can vary depending on the number of edge skin bars to be stacked, the gluing method, etc. For example, in some embodiments, the edge skin stacking and gluing device includes a centering mechanism disposed on the edge skin carrying platform in the carrying and conveying unit. In some embodiments, the edge skin stacking and gluing device includes a centering mechanism disposed on a mounting bracket or pre-pressing unit. In some embodiments, the edge skin stacking and gluing device includes a first centering mechanism (also referred to as a lower centering mechanism) disposed on the edge skin carrying platform in the carrying and conveying unit and a second centering mechanism (also referred to as an upper centering mechanism) disposed on the mounting bracket or pre-pressing unit.

[0148] When the application Figure 1and Figure 7 In the edge-layer stacking and gluing device of the illustrated embodiment, the first edge-layer bar 102 with its arc-shaped top cut off is transported by the transport unit 1313 to the edge-layer support platform 13111 of the edge-layer support and conveying unit 1311. The first edge-layer bar 102 is placed on the edge-layer support platform 13111 with its bottom surface facing down and its top surface facing up. At this time, the edge-layer support platform 13111 is vertically raised to a set height by the lifting mechanism 13113. The first edge-layer bar 102 is centered using the centering mechanism (i.e., the first centering mechanism 1312 and the second centering mechanism 1314). Simultaneously, the gluing unit 13151 is moved to allow the edge-layer to be aligned. The top surface of the first edge leather rod 102 on the leather support platform 13111 is coated with adhesive. The lifting mechanism 13113 drives the edge leather support platform 13111 to descend vertically a certain distance (e.g., a distance equivalent to the thickness of one edge leather rod). The transport unit 1313 transports the second edge leather rod 102, with its arc-shaped top cut off, to the edge leather support platform 13111 of the edge leather support and conveying unit 1311 and stacks it on top of the first edge leather rod 102. The bottom surface of the second edge leather rod 102 contacts the top surface of the first edge leather rod 102 through the applied adhesive. Simultaneously, a centering mechanism (i.e., the first centering mechanism 1312 and the second centering mechanism 1314) performs a centering operation to ensure that the second edge leather rod... The second edge strip 102 is vertically aligned with the first edge strip 102. The lifting mechanism 13113 drives the edge strip support platform 13111 to rise vertically a certain distance, causing the top surface of the second edge strip 102 to contact the pre-pressing unit 13153, thus pre-pressing both the first and second edge strips 102. The lifting mechanism 13113 then drives the edge strip support platform 13111 to descend vertically a certain distance, moving the glue application unit 13151 to apply glue to the top surface of the second edge strip 102. This process is repeated. The process involves: using the transport unit 1313 to transport the next edge bar 102 to the edge bar support platform 13111 and stacking it on top of the previous edge bar 102; using the centering mechanism (i.e., the first centering mechanism 1312 and the second centering mechanism 1314) to perform centering operations so that each edge bar is vertically aligned; using the lifting mechanism 13113 to drive the edge bar support platform 13111 to rise vertically a certain distance so that the pre-compression unit 13153 can pre-compress each edge bar; and so on, until the predetermined number of edge bars are stacked and glued to form an edge bar stack 103; finally, using the conveying mechanism 13115 to drive the edge bar support platform 13111 and the edge bar stack 103 it carries to move out along the conveying direction.

Taking a pressing plate as the pressing component and a pressing cylinder as the pressing component driving source as an example, the pressing cylinder is mounted on a mounting bracket, and the output shaft of the pressing cylinder is associated with the pressing plate through a transmission structure. The pressing plate is located above the edge bar stack bearing unit and the edge bar stack it supports. The pressing cylinder can drive the pressing plate to move vertically up and down. For example, the pressing plate is driven to descend vertically and press against the edge bar stack below it. Under the force applied by the pressing cylinder, the edge bar stack is pressed and compacted. Under the force applied by the pressing cylinder, the edge bar stack is pressed and compacted and continuously maintained for a preset curing time.

Figure 1 and Figure 10 In some embodiments, the third edge skin support device 151 includes a third edge skin support platform 1511 for supporting the edge skin bar stack 104, which is formed by stacking multiple edge skin bars 102. In this application, the edge skin bar stack to be cut is cut horizontally. In some embodiments, the edge skin bar stack to be cut horizontally on the third edge skin support device means that the edge skin bar stack to be cut is placed on the third edge skin support platform with the bottom surface down and the top surface up or the bottom surface up and the top surface down (i.e., with the bottom surface or the top surface as the support surface). In some embodiments, the edge skin bar stack to be cut horizontally on the third edge skin support device means that the edge skin bar stack to be cut is placed on the third edge skin support platform with the bottom surface in front and the top surface behind or the bottom surface behind and the top surface in front.

[0158] To ensure the stable placement of the edge bar stack on the third edge bar support platform, the third edge bar support device may further include a third edge bar positioning mechanism for positioning the edge bar stack supported by the third edge bar support platform. Figure 1 and Figure 10In some embodiments, the third edge-skin bearing device 151 may further include third edge-skin positioning mechanisms 1513 located on the left and right sides of the third edge-skin bearing platform 1511. Thus, when the third cutting device performs a cutting operation on the edge-skin bar stack carried by the third edge-skin bearing platform, the third edge-skin positioning mechanisms can be used to position the edge-skin bar stack carried by the third edge-skin bearing platform to avoid relative displacement between the edge-skin bar stack and the third edge-skin bearing platform during the cutting operation, which would affect the cutting quality. In some embodiments, the third edge-skin positioning mechanism may be, for example, an edge-skin bar stack clamping mechanism for clamping the edge-skin bar stack located therebetween. For example, in some examples, the edge-skin bar stack clamping mechanism may include a first movable clamp and a second movable clamp arranged opposite each other along a second direction, driven by a clamp driving source associated with the first movable clamp and the second movable clamp to move towards each other or away from each other. In some examples, the edge bar stack clamping mechanism may include a backing and a movable clamp arranged opposite each other along a second direction, the movable clamp being driven by a clamp drive source associated with the movable clamp to face toward or away from the backing.

[0159] To ensure that the stack of edge bars to be cut is placed on the third edge bar support device, in some embodiments, the cutting device further includes: a cutting and transferring device for transferring the stack of edge bars to the third edge bar support device or moving the cut edge bar stack segments along the conveying direction. Figure 1 and Figure 10 In some embodiments, the cutting device 15 may further include a cutting and conveying device 155 arranged along a first direction. In some embodiments, the cutting and conveying 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 roller assembly is arranged along the first direction, the roller assembly including two rows of roller groups arranged side by side along the first direction, each row of roller groups including multiple rollers arranged along the first direction, the axis of the rollers being aligned with the second direction, the roller surface of each roller forming a side bar stack bearing surface, the side bar stack bearing surface being, for example, aligned with the horizontal plane, and the distance between the two rows of roller groups being less than the width of the side bar stack being carried. Taking the roller assembly as an example, multiple rollers are arranged along the first direction, the axis of the rollers being aligned with the second direction, the roller surface of each roller forming a side bar stack bearing surface, the side bar stack bearing surface being, for example, aligned with the horizontal plane. The motor assembly includes a motor, with each roller / roller corresponding to one motor, or multiple rollers / rollers sharing one motor. The motor drives the corresponding roller / roller to rotate, and the friction between the roller / roller and the edge bar stack or edge bar stack section placed on it can be used to drive the edge bar stack or edge bar stack section to be conveyed along the first direction.

[0160] In some embodiments, the cutting and transferring device may include a transmission guide rail and a transmission drive mechanism. The transmission guide rail is arranged along a 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 drive source. For example, in some embodiments, the transmission chain assembly may include a transmission chain and a drive source. The transmission chain may be a strip-shaped or ring-shaped chain, arranged along the first direction and associated with a transmission member. The drive source is used to drive the transmission chain to move so that the associated transmission member drives the edge bar stack to move along the transmission guide rail. The drive source is, for example, a drive motor with a sprocket associated with the transmission chain, and the drive motor can drive the sprocket to rotate in both directions. For example, in some embodiments, the drive chain assembly may include at least two drive chains and a drive source. The at least two drive chains may be strip-shaped or ring-shaped chains. One drive chain is arranged along a first direction and associated with a transmission element. The other at least one drive chain is associated with the drive chain arranged along the first direction via a toothed sleeve, and the other side of the at least one drive chain is associated with the drive source. The drive source drives the other at least one drive chain and the associated drive chain arranged along the first direction to move such that the transmission element associated with the drive chain arranged along the first direction moves the edge bar stack along the drive guide. The drive source is, for example, a drive motor with a sprocket associated with the other at least one drive chain, and the drive motor can drive the other at least one drive chain in both forward and reverse directions. In some embodiments, the transmission element may be, for example, a transmission stop or a transmission clamp.

[0161] In some embodiments, in the severing device, the second cutting device includes: a second cutting mounting structure, at least one second cutting unit, and a cutting unit lifting mechanism. In such... Figure 1 and Figure 10 In the embodiment shown, the second cutting device 153 includes: a second cutting mounting structure 1531, at least one second cutting unit 1533, and a cutting unit lifting mechanism.

[0162] The second cutting mounting structure is mounted on the cutting machine base and corresponds to the second cutting area. (As shown in the image) Figure 1 and Figure 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 other structures.

[0163] The second cutting unit includes: multiple second cutting wheels and a second cutting line. (As shown in the image) Figure 1 and Figure 10In the embodiment shown, the second cutting unit 1533 may include: a plurality of second cutting wheels 1532 and a second cutting line 1534, the second cutting line 1534 being wound around the plurality of second cutting wheels 1532 to form at least one second cutting wire saw 1535.

[0164] The second cutting wheel 1532 is provided with at least one cutting groove for winding the second cutting line 1534. The cutting groove can define the position of the second cutting line to control the cutting accuracy. Any second cutting wire saw 1535 is formed by winding the second cutting line 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.

[0165] In such Figure 1 and Figure 10 In the illustrated embodiment, at least one second wire saw 1535 is located in the second direction. 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.

[0166] like Figure 1 and Figure 10 As shown, for example, in some embodiments, the second cutting device 153 includes a plurality of second cutting units 1533, each of which includes a plurality of second cutting wheels 1532, such as four second cutting wheels 1532: second cutting wheel 1532a, second cutting wheel 1532b, second cutting wheel 1532c, and second cutting wheel 1532d. The wheel surfaces of the four second cutting wheels 1532 are all located in a vertical plane and together form a quadrilateral (e.g., a rectangle, trapezoid, etc.). The second cutting wheel 1532a and the second cutting wheel 1532d... 2b is arranged below and parallel to each other along the second direction. The second cutting wheel 1532c and the second cutting wheel 1532d are arranged above and parallel to each other 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). The at least one second cutting wire saw 1535 is arranged along the second direction.

[0167] In some embodiments, the second cutting line is wound around each of the second cutting wheels in an end-to-end manner to form a loop cutting line (also known as a closed-loop cutting line). In such... Figure 1 and Figure 10In the embodiment shown, the second cutting line 1534 is wound around the four second cutting wheels 1532 in a continuous manner to form a ring cutting line (also known as a closed-loop cutting line).

[0168] In the second cutting unit, multiple second cutting wheels are wound around a circular cutting wire. In this example, the cutting device can eliminate the need for a wire storage spool. The circular cutting wire is driven by a cutting wire drive device to maintain high-speed operation. Furthermore, the circular cutting wire can run in the same direction during the cutting operation (unlike traditional non-circular cutting wires with wire storage spools, which alternate between forward and reverse rotation). Thus, the cutting device can achieve high-precision cutting operations, avoiding problems such as wavy cut surfaces caused by changes in cutting wire direction or speed in existing cutting methods. Simultaneously, the circular cutting wire effectively reduces the total length of the cutting wire required by the cutting device, lowering production costs.

[0169] In some embodiments, the cutting wire drive device is a motor with a power output shaft connected to a second cutting wheel, so that the second cutting wire can be driven by the wound second cutting wheel to run along the winding direction. Of course, in specific implementations, the cutting wire drive device can also be other drive sources such as a hydraulic motor, as long as it can drive the cutting wire to run, and this application does not impose any restrictions.

[0170] The second cutting unit in this application may further include a second transition wheel, which is used to reverse or guide the second cutting line, or, alternatively, the second transition wheel can be used to adjust the tension of the second cutting line. The number of the second transition wheels may be one or more, depending on the layout requirements.

[0171] The second transition wheel, while guiding and tractioning the second cutting wire, also serves as a tensioning wheel for adjusting the tension of the second cutting wire. This tensioning wheel is used to adjust the tension of the second cutting wire, which can reduce the probability of wire breakage and thus reduce material consumption.

[0172] like Figure 1 and Figure 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, the second cutting wheels 1532a, 1532b, 1536a, and 1536b have their surfaces located in a vertical plane and collectively form a quadrilateral (e.g., a rectangle, trapezoid, etc.). The second cutting wheels 1532a, 1532b, 1536a, and 1536b have their surfaces located in a vertical plane and collectively form a quadrilateral (e.g., a rectangle, trapezoid, etc.). The second cutting wheel 1532b is arranged in parallel front and back along the second direction, while the second transition wheel 1536a and the second transition wheel 1536b are arranged 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 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). The at least one second cutting wire saw 1535 is arranged along the second direction.

[0173] As previously described, the second cutting line is wound around a plurality of second cutting wheels or a plurality of second cutting wheels and a plurality of second transition wheels to form a second cutting wire saw 1535 between the second cutting wheels (e.g., between the second cutting wheel 1532a and the second cutting wheel 1532b). Therefore, to adjust the line length of the second cutting wire saw 1535, it can be achieved by adjusting the spacing between the second cutting wheels 1532a and the second cutting wheels 1532b, which can be achieved by changing the position of at least one of the second cutting wheels 1532a and the second cutting wheels 1532b.

[0174] Furthermore, the second wire saw can still have other variations, such as... Figure 1 and Figure 10In the illustrated embodiment, the second cutting wheel 1532a and the second cutting wheel 1532b are arranged in parallel along the second direction. 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 (e.g., 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 thereto. 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 with respect to the second direction. The vertical plane is composed of the second direction and a third direction. 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 of less than or equal to 45° (≤±45°) with respect to the second direction. In this implementation, in the third direction, one of the second cutting wheels 1532a and 1532b is positioned below and the other is positioned above. For example, the second cutting wheel 1532a is below and the second cutting wheel 1532b is above (the angle formed by the second cutting wheel 1532a below and the second cutting wheel 1532b above with the second cutting wheel 1532b above can be called the positive angle). Alternatively, the second cutting wheel 1532b is above and the second cutting wheel 1532a is below (the angle formed by the second cutting wheel 1532a above and the second cutting wheel 1532b above with the second cutting wheel 1532b above can be called the positive angle). The angle formed by the second cutting wire saw and the second direction is called the negative angle. Thus, during the severing cut, the lower portion of the second cutting wire saw 1535 enters the edge bar stack 104 first, and during the descent, the upper portion of the second cutting wire saw 1535 enters the edge bar stack 104 later, continuously cutting the edge bar stack 104. Finally, the lower portion of the second cutting wire saw 1535 exits the edge bar stack 104 first, followed by the upper portion, until the edge bar stack 104 is severed, forming multiple edge bar stack segments 105. The second direction angle can be changed according to the cutting process requirements and the size specifications of the edge bar to be cut. For example, the angle of the second direction angle can be adjusted by changing the position of one or both of the second cutting wheels 1532a and 1532b associated with the second cutting wire saw 1535.

[0175] In some embodiments, the second cutting unit further includes a tension adjustment mechanism. In wire EDM, the tension of the cutting wire affects the yield and processing accuracy. The tension adjustment mechanism detects and adjusts the tension so that the tension of the cutting wire reaches a set threshold and remains at a constant value or within a certain range allowed by the constant value during cutting.

[0176] In some embodiments, the tension adjustment mechanism is associated with a transition wheel, which in the wire cutting unit serves as a tensioning wheel for adjusting the tension of the cutting wire while simultaneously guiding and pulling the cutting wire.

[0177] Tensioners are used to adjust the tension of the cutting wire, reducing the probability of wire breakage and thus reducing material consumption. The cutting wire plays a crucial role in cutting operations, but even the best wire has limitations in elongation and wear resistance. This means that the wire gradually thins during continuous operation until it eventually breaks. Therefore, modern wire EDM equipment generally incorporates a wire tension compensation mechanism to compensate for the elongation of the wire during its reciprocating motion; the use of a tensioner is one such mechanism.

[0178] For example, in some embodiments, the tension adjusting mechanism can detect tension and adjust the tension based on the detection result. The method of tension adjustment is not limited; for example, it can be achieved by adjusting the second transition wheel. In some cases, when the detected tension is below the set requirement, the position of at least one of the two second transition wheels is adjusted, for example, by moving the second transition wheel outward to increase the circumference enclosed by the second cutting wheels and the second transition wheels, thereby increasing the tension. In some cases, when the detected tension exceeds the set requirement, the position of at least one of the two second transition wheels is adjusted, for example, by moving the second transition wheel inward to decrease the circumference enclosed by the second cutting wheels and the second transition wheels, thereby decreasing the tension.

[0179] In some embodiments, the second cutting unit may further include at least one second adjusting mechanism for driving the plurality of second cutting wheels to move relative to the second cutting mounting structure in a direction perpendicular to the wheel surface.

[0180] The second cutting assembly can switch the second cutting line between different cutting slots of the second cutting wheel based on the second adjusting mechanism, or adjust the position of the second cutting wire saw (e.g., in the first direction) to change the cutting position (or processing specifications) relative to the silicon rod. In practical applications, the second adjusting mechanism may include, for example: a lead screw, arranged in the orthogonal direction of the second cutting wheel surface and threadedly connected to the second cutting wheel; a drive source for driving the lead screw to rotate. Alternatively, the second adjusting mechanism may include, for example: a telescopic member, arranged in the orthogonal direction of the second cutting wheel surface and associated with the second cutting wheel; a drive source for driving the telescopic member to telescopically move in the orthogonal direction of the second cutting wheel surface. Alternatively, the second adjusting mechanism may include, for example: a rack, arranged in the orthogonal direction of the second cutting wheel surface on the second cutting wheel; a transmission gear, meshing with the rack; a drive source for driving the transmission gear to rotate.

[0181] The cutting unit lifting mechanism is used to drive the at least one second cutting unit to move vertically relative to the second cutting mounting structure.

[0182] In some embodiments, the at least one second cutting unit is movably mounted on the second cutting mounting structure via a second cutting wire frame. That is, at least one second cutting unit is mounted on the second cutting wire frame, and the second cutting wire frame and the at least one second cutting unit thereon are driven to move vertically relative to the second cutting mounting structure by a cutting unit lifting mechanism.

[0183] In some embodiments, the second cutting unit corresponds one-to-one with the second cutting wire frame, that is, each second cutting unit is movably mounted on the second cutting mounting structure through a corresponding second cutting wire frame.

[0184] In some embodiments, multiple second cutting units share a single second cutting wire frame; that is, multiple second cutting units are movably mounted on the second cutting mounting structure via a corresponding second cutting wire frame. For example... Figure 1 and Figure 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 every two second cutting units may form a group, and the two groups of second cutting units are respectively disposed on opposite sides of the second cutting mounting structure, with two second cutting units in each group movably mounted on the second cutting mounting structure via a corresponding second cutting wire frame.

[0185] In some implementations, the lifting mechanism of the cutting unit may include a lifting guide rail, a slider, and a lifting drive unit. The lifting guide rail is disposed on the second cutting mounting structure along a third direction. The slider is disposed on the second cutting wire frame and adapted to the corresponding lifting guide rail. The lifting drive unit drives the second cutting wire frame to move up and down along the lifting guide rail. In practical applications, to ensure stable lifting and lowering of the second cutting wire frame on the second cutting mounting structure, a dual-guide rail design can be adopted, i.e., two lifting guide rails are used, arranged in parallel. Furthermore, the lifting drive unit may further include a lifting screw and a lifting motor. The lifting screw is disposed along a third direction and connected to the second cutting wire frame, and the lifting motor (which may be, for example, a servo motor) is connected to the lifting screw. Thus, the lifting motor drives the lifting screw to rotate, thereby enabling the second cutting wire frame to move up and down along the lifting guide rail. The implementation of the lifting drive unit is not limited to this. Other components that can drive the second cutting wire frame 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 drive gear meshing with the lifting rack, and a drive motor that drives the drive gear to rotate.

[0186] In the cutting device, at least one of the third edge skin bearing device and the second cutting device further includes a displacement drive mechanism.

[0187] In some embodiments, the third edge skin bearing device includes an edge skin displacement driving mechanism for driving the third edge skin bearing device and the stack of edge skin bars it supports to shift. Figure 1 and Figure 10 In the illustrated embodiment, driving the third edge skin support device and the stack of edge skin bars it supports to shift may include driving the third edge skin support device and the stack of edge skin bars it supports to move along a first direction.

[0188] In some embodiments, the second cutting device includes a cutting displacement drive mechanism for driving the second cutting mounting structure and at least one second cutting unit thereon to shift. Figure 1 and Figure 10 In the illustrated embodiment, driving the second cutting mounting structure and at least one second cutting unit thereon to shift may include driving the second cutting mounting structure and at least one second cutting unit thereon to shift along a first direction.

[0189] In some embodiments, the third edge-skin bearing device includes an edge-skin displacement driving mechanism for driving the third edge-skin bearing device and the stack of edge-skin bars it carries to shift, and the second cutting device includes a cutting displacement driving mechanism for driving the second cutting mounting structure and at least one second cutting unit on it to shift. In such embodiments... Figure 1 and Figure 10 In the illustrated embodiment, driving the third edge skin support device and the edge skin bar stack it supports to shift may include driving the third edge skin support device and the edge skin bar stack it supports to move along a first direction, and driving the second cutting mounting structure and at least one second cutting unit on it to shift may include driving the second cutting mounting structure and at least one second cutting unit on it to shift along the first direction.

[0190] In some embodiments, the displacement driving mechanism may include a displacement guide rail and a displacement driving unit. Taking an edge skin displacement driving mechanism as an example, the edge skin displacement driving mechanism includes an edge skin displacement guide rail and an edge skin displacement driving unit. The edge skin displacement guide rail is arranged along a first direction and is used to mount the third edge skin bearing device. The edge skin displacement driving unit is used to drive the third edge skin bearing device to move along the edge skin displacement guide rail. Taking a cutting displacement driving mechanism as an example, the cutting displacement driving mechanism includes a cutting displacement guide rail and a cutting displacement driving unit. The cutting displacement guide rail is arranged along a first direction and is used to mount the second cutting mounting structure and at least one second cutting unit thereon. The cutting displacement driving unit is used to drive the second cutting mounting structure and at least one second cutting unit thereon to move along the cutting displacement guide rail.

[0191] In some embodiments, the shifting drive unit includes a shifting gear, a drive gear, and a drive source. The shifting gear is arranged along a first direction and parallel to the shifting guide rail. The drive gear meshes with the shifting gear. The drive gear is driven to rotate by the drive source, and its teeth mesh with the shifting gear, traveling in accordance with the shifting gear. This causes the third edge-supporting device or the second cutting mounting structure associated with the drive gear, and at least one second cutting unit thereon, to move accordingly on the shifting guide rail. The drive source is, for example, a drive motor.

[0192] In some embodiments, the shifting drive unit includes a shifting lead screw and a drive source, wherein the shifting lead screw is disposed along a first direction and associated with the third edge support device or the second cutting mounting structure and at least one second cutting unit thereon, and the drive source is used to drive the shifting lead screw to rotate so that the associated third edge support device or the second cutting mounting structure and at least one second cutting unit thereon move along the shifting guide. The drive source is, for example, a drive motor.

[0193] As mentioned above, in some embodiments, placing the stack of edge strips to be cut horizontally on the third edge strip support device means that the stack of edge strips to be cut is placed on the third edge strip support device with the bottom surface facing forward and the top surface facing backward or vice versa. Conversely, the stack of edge strips undergoing curing operations in the curing zone is placed with the bottom surface facing down and the top surface facing up. Therefore, when transferring the stack of edge strips from the curing zone to the third edge strip support device, it is necessary to flip the stack of edge strips over.

[0194] In this application, the cutting device further includes a cutting and folding device for folding the edge bar stack before placing it onto the third edge bar support device. In some embodiments, the cutting and folding device is connected to the third edge bar support device for folding the edge bar stack and transferring the folded edge bar stack onto the third edge bar support device. In some embodiments, the cutting and folding device is connected to the cutting and transferring device for folding the edge bar stack before or after the cutting and transferring device transfers the edge bar stack. Figure 1 and Figure 8 In the embodiment shown, the cutting device further includes a cutting and folding device 157, which is located between the curing zone and the cutting and transferring device 155. The cutting and folding device 157 is used to fold the edge bar stack 104 before transferring it to the cutting and transferring device 155, so that the edge bar stack 104 is folded from the original bottom surface on the bottom and top surface on the top to the bottom surface on the back and the top surface on the front.

[0195] In some embodiments, the folding device includes a folding plate, a rotating shaft, and a rotating mechanism. In such... 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, with the included angle between the first panel and the second panel approximately 90°. For example, the first panel corresponds to the bottom surface of the stack of edge bars, and the second panel corresponds to one side of the stack of edge bars. The spatial rotation angle of the folding plate is also approximately controlled at around 90°. The junction of the first panel and the second panel of the folding plate is mounted on the rotating shaft. The rotating mechanism is connected to the rotating shaft for transmission, and the folding plate rotates forward and backward 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, with the rotating motor driving the gear assembly to rotate, thereby causing the folding plate to rotate around the rotating shaft. In some embodiments, the rotating mechanism may include a support rod and a telescopic cylinder, with the support rod connecting the telescopic cylinder and one of the panels of the folding plate (the first panel or the second panel).

[0196] When the application Figure 8 When the folding device shown folds the edge bar stack, firstly, the edge bar stack 104 (bottom surface down, top surface up), which has been cured in the curing zone, is transferred to the folding device 157. At this time, the first panel of the folding device 157 corresponds to and supports the bottom surface of the edge bar stack 104, and the second panel of the folding device 157 corresponds to (either touching or not touching) one side of the edge bar stack 104. Then, the rotation source of the folding device 157 drives the rotating shaft to rotate and drives the folding plate to flip. After flipping approximately 90°, the edge bar stack 104 completes a 90° flip and is placed on the folding device 157 with its side facing down, forming as shown. Figure 9 The state shown.

[0197] When a cutting device equipped with a folding mechanism cuts off a stack of edge bar stacks, firstly, the folding mechanism folds the stack so that the bottom surface is facing down and the top surface is facing up, while the sides are facing down. Next, the stack is transferred from the folding mechanism to the cutting and conveying device. Then, the cutting and conveying device transfers the stack to be cut to the third edge bar support device, where the stack is placed with its sides facing down (bottom surface in front and top surface behind, or bottom surface behind and top surface in front). Next, a fourth edge bar positioning mechanism positions the stack, ensuring its stability. Then, a cutting unit lifting mechanism drives at least one second cutting unit to descend vertically, where at least one second wire saw from the second cutting unit contacts and cuts the stack until the wire saw completely exits the stack, completing the cutting operation and forming the corresponding edge bar stack segment.

[0198] In the above embodiments, the second cutting device in the 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 drives at least one second cutting unit to move vertically to cut the edge bar stack. However, this is not a limitation, and the cutting device can still be modified in other ways.

[0199] In some embodiments, the second cutting device may include: a second cutting mounting structure, at least one second cutting unit, and a cutting unit translation mechanism.

[0200] The second cutting mounting structure 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 other structures.

[0201] The second cutting unit includes: a plurality of second cutting wheels and a second cutting line. For example, in some embodiments, the second cutting unit may include: a plurality of second cutting wheels and a second cutting line, the second cutting line being wound around the plurality of second cutting wheels to form at least one second wire saw.

[0202] The second cutting wheel is provided with at least one cutting groove for winding the second cutting line, which can define the position of the second cutting line to control the cutting accuracy. Any second cutting wire saw is formed by winding the second cutting line 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.

[0203] In some embodiments, at least one second wire saw is located in a 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 a vertical plane formed by the second direction and the third direction.

[0204] For example, in some embodiments, the second cutting device includes a plurality of second cutting units, each of which 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 a vertical plane and together form a quadrilateral (e.g., a rectangle, trapezoid, etc.). Two of the second cutting wheels are arranged in front and parallel to each other along a third direction, and the other two second cutting wheels are arranged in the back and parallel to each other along a third direction. A second cutting line is wound around the four second cutting wheels to form at least one second cutting line saw (e.g., a second cutting line saw is formed between the two front second cutting wheels). The at least one second cutting line saw is arranged along a third direction.

[0205] In some embodiments, the second cutting line is wound around each of the second cutting wheels in an end-to-end manner to form a loop cutting line (also known as a closed loop cutting line).

[0206] The second cutting unit in this application may further include a second transition wheel, which is used to reverse or guide the second cutting line, or, alternatively, the second transition wheel can be used to adjust the tension of the second cutting line. The number of the second transition wheels may be one or more, depending on the layout requirements.

[0207] The second transition wheel, while guiding and tractioning the second cutting wire, also serves as a tensioning wheel for adjusting the tension of the second cutting wire. This tensioning wheel is used to adjust the tension of the second cutting wire, which can reduce the probability of wire breakage and thus reduce material consumption.

[0208] For example, in some embodiments, the second cutting device includes a plurality of second cutting wheels and a plurality of second transition wheels, such as two cutting wheels and two transition wheels. The surfaces of the two cutting wheels and the two transition wheels are all located in a vertical plane and are generally arranged in a quadrilateral (e.g., a rectangle, a trapezoid, etc.). The two second cutting wheels are arranged in front and parallel to each other along a third direction, and the two second transition wheels are arranged in the back and parallel to each other along a third direction. The second cutting line is wrapped around the two cutting wheels and the two transition wheels to form at least one second cutting line saw (e.g., a second cutting line saw is formed between the two second cutting wheels). The at least one second cutting line saw is arranged along a third direction.

[0209] As mentioned above, the second cutting line is wound around multiple second cutting wheels or multiple second cutting wheels and multiple second transition wheels to form a second cutting line saw between the second cutting wheels. Therefore, to adjust the line length of the second cutting line saw, it can be achieved by adjusting the distance between the two second cutting wheels where the second cutting line saw is located. This can be achieved by changing the position of at least one of the two second cutting wheels.

[0210] Furthermore, the second wire saw can still have other variations. For example, in other embodiments, the position of the second wire saw can be located in a vertical plane and arranged at a third-direction angle with respect to a third direction. The vertical plane is composed of a second direction and a third direction, and the third-direction angle is less than or equal to 45° (≤±45°). That is, the wire cutting direction of the second wire saw can be located in the same vertical plane as the third direction and form an angle of less than or equal to 45° (≤±45°) with respect to the third direction. In this implementation, in the third direction, one second cutting wheel is in front and the other is behind (the angle formed by the upper second cutting wheel in front and the lower second cutting wheel behind with the third direction can be called a positive angle, or the angle formed by the upper second cutting wheel behind and the lower second cutting wheel in front with the third direction can be called a negative angle). Thus, during the cutting process, the front portion of the second cutting wheel enters the edge bar stack first, and during the translational advancement, the rear portion enters the edge bar stack later, continuously cutting the edge bar stack. Finally, the front portion of the second cutting wheel exits the edge bar stack first, followed by the rear portion, until the edge bar stack is cut off. The third direction angle can be changed according to the cutting process requirements and the size specifications of the edge bar to be cut. For example, the angle can be adjusted by changing the position of one or both second cutting wheels associated with the second cutting wheel.

[0211] In some embodiments, the second cutting unit further includes a tension adjustment mechanism.

[0212] In some embodiments, the tension adjustment mechanism is associated with a transition wheel, which in the wire cutting unit serves as a tensioning wheel for adjusting the tension of the cutting wire while simultaneously guiding and pulling the cutting wire.

[0213] In some embodiments, the second cutting unit may further include at least one second adjusting mechanism for driving the plurality of second cutting wheels to move relative to the second cutting mounting structure in a direction perpendicular to the wheel surface.

[0214] 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.

[0215] 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 mounting structure, thereby causing the at least one second cutting unit to translate relative to the third edge support device.

[0216] The cutting unit translation mechanism may include: a translation guide rail and a translation drive unit. The translation guide rail is arranged along a 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.

[0217] In some embodiments, the translation drive unit includes a translation rack, a drive gear, and a drive source. The translation rack is arranged along a second direction and parallel to the translation guide rail. The drive gear is disposed on at least one second cutting unit or a second cutting wire frame associated with the at least one second cutting unit, and meshes with the translation rack to drive the at least one second cutting unit to move along the translation guide rail. The drive gear is driven to rotate by the drive source, and its teeth mesh with the translation rack, traveling in accordance with the translation rack. The at least one second cutting unit connected to the drive gear or the second cutting wire frame associated with the at least one second cutting unit thus generates corresponding movement on the translation guide rail. The drive source is, for example, a drive motor.

[0218] In some embodiments, the translation drive unit includes a translation screw and a drive source, wherein the translation screw is arranged along a second direction and 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. The drive source is, for example, a drive motor.

[0219] When cutting the edge bar stack using the cutting device, firstly, the edge bar stack to be cut is transferred to the third edge bar support device using the cutting and transferring device. At this time, the edge bar stack is placed on the third edge bar support device with the bottom surface facing down and the top surface facing up. The second cutting wire is driven by the cutting wire drive device 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 bar stack carried by the third edge bar support device so that the edge bar stack can be cut by the second cutting wire saw to form multiple edge bar stack segments.

[0220] Of course, in some embodiments, the third edge skin support device is a movable design, that is, the third edge skin support device may be equipped with a support device translation mechanism for driving the third edge skin support device to translate relative to the second cutting device. Regarding the support device translation mechanism, please refer to the aforementioned cutting unit translation mechanism, which will not be repeated here.

[0221] The ear-cutting device in this application is used to perform ear-cutting operations on the stacked segments of the edge bar along the thickness direction of the edge bar to remove the ear portion of each edge bar in the stacked segments of the edge bar.

[0222] The ear cutting device includes a fourth edge skin supporting device and a third cutting device, wherein the fourth edge skin supporting device is used to support the edge skin bar stack section, and the third cutting device is used to perform ear cutting operation on the edge skin bar stack section supported by the fourth edge skin supporting device to remove the ear part of each edge skin bar in the edge skin bar stack section.

[0223] The fourth edge skin support device is used to support the stacked edge skin bar segments. In some embodiments, the fourth edge skin support device includes a fourth edge skin support platform. See also [link to relevant documentation] in this application. Figure 10 Displayed as Figure 1 A schematic diagram of a middle ear cutting device. (In such cases...) Figure 1 and Figure 10 In the illustrated embodiment, the ear cutting device 17 may include a fourth side skin support device 171 and a third cutting device 173. To facilitate cutting the ear on opposite sides of the side skin stack segments, the side skin stack segments to be cut are placed on the fourth side skin support platform 1711 with the cut surface as the support surface. Furthermore, the ear cutting device includes two fourth side skin support devices 171, which are spaced apart along a first direction, and each fourth side skin support device 171 can support at least one side skin stack segment 105.

[0224] To ensure the stable placement of the edge bar stack segments on the fourth edge bar support platform, the fourth edge bar support device may further include a fourth edge bar positioning mechanism for positioning the edge bar stack segments supported by the fourth edge bar support platform. Figure 1 and Figure 10 In the embodiments, the fourth edge skin bearing device 171 may further include a fourth edge skin positioning mechanism 1713 located at both ends of the fourth edge skin bearing platform 1711 along the second direction. Thus, when the third cutting device is used to perform ear-cutting operations on the edge skin bar stack section carried by the fourth edge skin bearing platform, the fourth edge skin positioning mechanism can be used to position the edge skin bar stack section carried by the fourth edge skin bearing platform, thereby preventing relative displacement between the edge skin bar stack section and the fourth edge skin bearing platform or relative displacement between the ear section to be cut and the edge skin bar stack section during the ear-cutting operation, which would affect the cutting quality. In some embodiments, the fourth edge positioning mechanism may be, for example, an edge clamping mechanism. For an edge bar stack section, the edge clamping mechanism may include two jaws or clamping blocks arranged along the thickness direction of the edge bar stack section and a drive source for driving the jaws or clamping blocks. When in use, the placed edge bar stack section is located in the placement space between the two jaws or clamping blocks. The drive source drives the two jaws or clamping blocks to move or actuate towards each other along the thickness direction of the edge bar stack section, thereby clamping the edge bar stack section located therebetween. Alternatively, the fourth edge positioning mechanism may include a backing and a movable gripper or movable clamping block, as well as a drive source for driving the movable gripper or movable clamping block. The backing is located on one side, and the movable gripper or movable clamping block is located on the other side along the thickness direction of the edge bar stack section. When in use, the placed edge bar stack sections are respectively located in the placement space formed by the backing and the movable gripper or movable clamping block. The drive source drives the movable gripper or movable clamping block to move towards the backing along the thickness direction of the edge bar stack section, clamping the edge bar stack section located therein.

[0225] Furthermore, in some embodiments, the fourth side leather support device may include ear support mechanisms, which are disposed on opposite sides of the fourth side leather support platform to support the ears of the supported side leather rod stack segments. Figure 1 and Figure 10In the illustrated embodiment, ear support mechanisms 1715 are respectively provided on both sides of the fourth side skin support platform 1711. In some embodiments, the ear support mechanism 1715 may include a support member and an adjusting member associated with the support member. The support member may be, for example, a support plate, a support frame, or a support block. The support member is axially connected to the fourth side skin support platform, and the adjusting member may be, for example, a cylinder, a hydraulic cylinder, or an elastic telescopic member. In practical applications, during ear cutting, the adjusting member drives the support member to a supporting state to support the ear of the stacked segment of the side skin bar at the corresponding position until the ear cutting is completed. The cut ear is supported by the support member. Then, the adjusting member drives the support member to rotate from the supporting state to the unloading state, thereby unloading the supported ear.

[0226] To place the stack of edge strips to be cut onto the fourth edge strip support device, in some embodiments, the ear-cutting device further includes a cutting and conveying device for flipping and conveying the cut edge strip stack segments to the fourth edge strip support device. In some embodiments, the cutting and conveying device may be, for example, a conveying clamp or a suction cup conveying robot. Figure 1 and Figure 10 In one embodiment, the ear cutting device 17 further includes a cutting and transporting device 175. The cutting and transporting device 175 is exemplified by a suction cup transporting robot. The suction cup transporting robot is flexible and can move up and down, move left and right, move forward and backward, and rotate. It can pick up the cut edge bar stack segment 105 from the third edge bar support device 151 of the cutting device 15 and transfer it to the fourth edge bar support device 171 of the ear cutting device 17. The edge bar stack segment placed on the fourth edge bar support device 171 is rotated 90° compared to when it is placed on the third edge bar support device, so that the cut surface of the edge bar stack segment 105 is down, the bottom surface is back and the top surface is in front (or the bottom surface is in front and the top surface is back), and the two ears are located on opposite sides along the first direction.

[0227] In some embodiments, the third cutting device in the ear cutting apparatus includes: a third cutting mounting structure, at least one third cutting unit, and a cutting unit lifting mechanism. In such... Figure 1 and Figure 10 In the embodiment shown, the third cutting device 173 includes: a third cutting mounting structure 1731, at least one third cutting unit 1733, and a cutting unit lifting mechanism.

[0228] The third cutting mounting structure is mounted on the cutting machine base and corresponds to the third cutting area. (As shown in the image) Figure 1 and Figure 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 other structures.

[0229] The at least one third cutting unit is disposed on the third cutting mounting structure, and the third cutting unit includes: a plurality of third cutting wheels and a third cutting line. In such a way... Figure 1 and Figure 10 In the illustrated embodiment, the third cutting mounting structure 1731 has third cutting units 1733 on both its left and right sides, with two third cutting units 1733 on each side. Each third cutting unit 1733 may include multiple third cutting wheels 1732 and a third cutting line 1734, the third cutting line 1734 being wound around the multiple third cutting wheels 1732 to form at least one third cutting wire saw 1735.

[0230] The third cutting wheel 1732 is provided with at least one cutting groove for winding the third cutting line 1734. The cutting groove can define the position of the third cutting line to control the cutting accuracy. Any third cutting wire saw 1735 is formed by winding the third cutting line 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.

[0231] In such Figure 1 and Figure 10 In the illustrated embodiment, at least one third wire saw 1735 is located in the second direction. 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.

[0232] like Figure 1 and Figure 10As shown, for example, in some embodiments, the third cutting device 173 includes multiple third cutting units, and any third cutting unit 1733 includes multiple third cutting wheels 1732, such as four third cutting wheels 1732: third cutting wheel 1732a, third cutting wheel 1732b, third cutting wheel 1732c, and 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 (e.g., a rectangle, trapezoid, etc.). Among them, third cutting wheel 1732a and third cutting wheel 1732b The third cutting wheel 1732c and the third cutting wheel 1732d are arranged in parallel front and back along the second direction below, and the third cutting line 1734 is arranged in parallel front and back along the second direction above. The third cutting line 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.

[0233] In some embodiments, the third cutting line is wound around each of the third cutting wheels in an end-to-end manner to form a loop cutting line (also known as a closed-loop cutting line). In such... Figure 1 and Figure 10 In the embodiment shown, the third cutting line 1734 is wound around the four third cutting wheels 1732 in a continuous manner to form a ring cutting line (also known as a closed-loop cutting line).

[0234] The multiple third cutting wheels in the third cutting unit are wound around a circular cutting wire. In this example, the ear cutting device can eliminate the need for a wire storage spool. The circular cutting wire is driven by a cutting wire drive device to maintain high-speed operation. Furthermore, the circular cutting wire can run in the same direction during the cutting operation (unlike traditional non-circular cutting wires with wire storage spools, which alternate between forward and reverse rotation). Thus, the ear cutting device can achieve high-precision cutting operations, avoiding problems such as wavy cut surfaces caused by changes in cutting wire direction or speed in existing cutting methods. Simultaneously, the circular cutting wire effectively reduces the total length of the cutting wire required for the ear cutting device, lowering production costs.

[0235] In some embodiments, the cutting wire drive device is a motor with a power output shaft connected to a third cutting wheel, so that the third cutting wire can be driven by the wound third cutting wheel to run along the winding direction. Of course, in specific implementations, the cutting wire drive device can also be other drive sources such as a hydraulic motor, as long as it can drive the cutting wire to run, and this application does not impose any restrictions.

[0236] The third cutting unit in this application may further include a third transition wheel, which is used to reverse 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 may be one or more, depending on the layout requirements.

[0237] The third transition wheel, while guiding and tractioning the third cutting wire, also serves as a tensioning wheel for adjusting the tension of the third cutting wire. The tensioning wheel is used to adjust the tension of the third cutting wire, which can reduce the probability of wire breakage and thus reduce material consumption.

[0238] like Figure 1 and Figure 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, the third cutting wheel 1732a, the third cutting wheel 1732b, the third transition wheel 1736a, and the third transition wheel 1736b have their surfaces located in a vertical plane and collectively form a quadrilateral (e.g., a rectangle, a trapezoid, etc.). The third cutting wheel 1732a... The third cutting wheel 1732b is arranged below and parallel to each other along the second direction. The third transition wheel 1736a and the third transition wheel 1736b are arranged above and parallel to each other 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). The at least one third cutting wire saw 1735 is arranged along the second direction.

[0239] As previously described, the third cutting line 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 (e.g., between third cutting wheel 1732a and third cutting wheel 1732b). Therefore, to adjust the line length of the third cutting wire saw 1735, it can be achieved by adjusting the spacing between the third cutting wheels 1732a and third cutting wheels 1732b. This can be achieved by changing the position of at least one of the third cutting wheels 1732a and third cutting wheels 1732b.

[0240] Furthermore, the third wire saw can still have other variations, such as... Figure 1In the illustrated embodiment, the third cutting wheels 1732a and 1732b are arranged in parallel along the second direction. 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 (e.g., between the third cutting wheels 1732a and 1732b). The third cutting wire saw 1735 is arranged along the second direction, but is not limited thereto. In other embodiments, the position of the third cutting wire saw 1735 may be located in a vertical plane and arranged at a second directional angle with respect to the second direction. The vertical plane is composed of the second direction and a third direction. The second directional 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 of less than or equal to 45° (≤±45°) with respect to the second direction. In this implementation, in the third direction, one of the third cutting wheels 1732a and 1732b is positioned below and the other is positioned above. For example, the third cutting wheel 1732a is below and the third cutting wheel 1732b is above (the angle formed by the third cutting line formed by the third cutting wheel 1732a below and the third cutting wheel 1732b above and the second direction can be called the positive angle), or the third cutting wheel 1732b is above and the third cutting wheel 1732a is below (the angle formed by the third cutting line formed by the third cutting wheel 1732a above and the third cutting wheel 1732b above). The angle formed by the saw and the second direction is called the negative angle. Thus, during ear cutting, the lower portion of the third cutting wire saw 1735 first enters the edge bar stack section 105, and during its descent, the upper portion of the third cutting wire saw 1735 enters the edge bar stack section 105 later, continuously cutting the edge bar stack section 105. Finally, the lower portion of the third cutting wire saw 1735 exits the edge bar stack section 105 first, followed by the upper portion, until the ear 107 in the edge bar stack section 105 is removed, forming the edge bar stack 106. The second direction angle can be changed according to the cutting process requirements and the size specifications of the edge bar to be cut. For example, the angle of the second direction angle can be adjusted by changing the position of one or both of the third cutting wheels 1732a and 1732b associated with the third cutting wire saw 1735.

[0241] In some embodiments, the third cutting unit also includes a tension adjustment mechanism. In wire EDM, the tension of the cutting wire affects the yield and processing accuracy. The tension adjustment mechanism detects and adjusts the tension so that the tension of the cutting wire reaches a certain set threshold and remains at a constant value or within a certain range allowed by the constant value as the numerical center during cutting.

[0242] In some embodiments, the tension adjustment mechanism is associated with a transition wheel, which in the wire cutting unit serves as a tensioning wheel for adjusting the tension of the cutting wire while simultaneously guiding and pulling the cutting wire.

[0243] The tensioning wheel is used to adjust the tension of the cutting wire, which can reduce the probability of wire breakage and thus reduce material consumption. The cutting wire plays a crucial role in the cutting operation, but even the best cutting wire has limitations in elongation and wear resistance. This means that the cutting wire will gradually thin during continuous operation until it eventually breaks. Therefore, modern wire EDM equipment is generally designed with a wire tension compensation mechanism to compensate for the elongation of the cutting wire during its reciprocating movement; the tensioning wheel is one such implementation method.

[0244] like Figure 1 and Figure 10 As shown, for example, in some embodiments, the tension adjusting mechanism can detect tension and adjust the tension according to the detection result. The method of tension adjustment is not limited; for example, it can be achieved by adjusting the third transition wheel 1736. In some cases, when the detected tension is below 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, increasing the circumference enclosed by the third cutting wheels 1732 and the third transition wheels 1736, thereby increasing the tension. In some cases, when the detected 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, decreasing the circumference enclosed by the third cutting wheels 1732 and the third transition wheels 1736, thereby decreasing the tension.

[0245] In some embodiments, the third cutting unit may further include: at least one third adjusting mechanism for driving the plurality of third cutting wheels to move relative to the third cutting mounting structure in a direction perpendicular to the wheel surface.

[0246] The third cutting assembly can switch the third cutting line between different cutting slots of the third cutting wheel based on the third adjusting mechanism, or adjust the position of the third cutting wire saw (e.g., in the first direction) to change the cutting position (or processing specifications) relative to the silicon rod. In practical applications, the third adjusting mechanism may include, for example: a lead screw, arranged in the orthogonal direction of the third cutting wheel surface and threadedly connected to the third cutting wheel; a drive source for driving the lead screw to rotate. Alternatively, the third adjusting mechanism may include, for example: a telescopic member, arranged in the orthogonal direction of the third cutting wheel surface and associated with the third cutting wheel; a drive source for driving the telescopic member to telescopically move in the orthogonal direction of the third cutting wheel surface. Alternatively, the third adjusting mechanism may include, for example: a rack, arranged in the orthogonal direction of the third cutting wheel surface on the third cutting wheel; a transmission gear, meshing with the rack; a drive source for driving the transmission gear to rotate.

[0247] The cutting unit lifting mechanism is used to drive the at least one third cutting unit to move vertically relative to the third cutting mounting structure.

[0248] In some embodiments, the at least one third cutting unit is movably mounted on the third cutting mounting structure via a third cutting wire frame. That is, the at least one third cutting unit is mounted on the third cutting wire frame, and the third cutting wire frame and the at least one third cutting unit on it are driven to move vertically relative to the third cutting mounting structure by a cutting unit lifting mechanism.

[0249] In some implementations, the third cutting unit corresponds one-to-one with the third cutting wire frame, that is, each third cutting unit is movably mounted on the third cutting mounting structure through a corresponding third cutting wire frame.

[0250] In some embodiments, multiple third cutting units share a single third cutting wire frame; that is, multiple third cutting units are movably mounted on the third cutting mounting structure via a corresponding third cutting wire frame. For example... Figure 1 and Figure 10 In the embodiment shown, the third cutting installation structure 1731 is provided with a third cutting unit on both the left and right sides. Each side is provided with two third cutting units 1733. The two third cutting units 1733 located on the same side are movably mounted on the third cutting installation structure 1731 through a corresponding third cutting wire frame, and are used to perform ear cutting operations on the edge bar stack section 105 carried by the fourth edge bar bearing device 171 in the third cutting area.

[0251] In some implementations, the lifting mechanism of the cutting unit may include a lifting guide rail, a slider, and a lifting drive unit. The lifting guide rail is disposed on the third cutting mounting structure along a third direction. The slider is disposed on the third cutting wire frame and adapted to the corresponding lifting guide rail. The lifting drive unit drives the third cutting wire frame to move up and down along the lifting guide rail. In practical applications, to ensure stable lifting and lowering of the third cutting wire frame on the third cutting mounting structure, a dual-guide rail design can be adopted, i.e., two lifting guide rails are used, arranged in parallel. Furthermore, the lifting drive unit may further include a lifting screw and a lifting motor. The lifting screw is disposed along a third direction and connected to the third cutting wire frame, and the lifting motor (which may be, for example, a servo motor) is connected to the lifting screw. Thus, the lifting motor drives the lifting screw to rotate, thereby enabling the third cutting wire frame to move up and down along the lifting guide rail. The implementation of the lifting drive unit is not limited to this. Other components that can drive the third cutting wire frame to move up and down along the lifting guide rail are also applicable. For example, the lifting drive unit may include a lifting rack, a drive gear meshing with the lifting rack, and a drive motor that drives the drive gear to rotate.

[0252] In such Figure 1 and Figure 10In the illustrated embodiment, the third cutting device 173 includes four third cutting units 1733. The third cutting mounting structure 1731 has three third cutting units 1733 on both its left and right sides, with two third cutting units 1733 on each side. Two third cutting units 1733 on the same side form a third cutting unit assembly. Two third cutting units 1733 in the same assembly are movably mounted on the third cutting mounting structure 1731 via a corresponding third cutting wire frame. The two third cutting units 1733 in each assembly can form two parallel third cutting wire saws 1735, used to cut the two opposite ears of the edge bar stack section 105 carried on the fourth edge bar bearing device 171. Of course, in some other embodiments, for example, the third cutting device includes four third cutting units, which are combined in pairs to form two third cutting unit assemblies. Each third cutting unit assembly is mounted on a third cutting wire frame, that is, the first third cutting unit assembly is mounted on the first third cutting wire frame, and the second third cutting unit assembly is mounted on the second third cutting wire frame. The first third cutting wire frame can be moved vertically relative to the third cutting mounting structure by the first cutting unit lifting mechanism, and the second third cutting wire frame can be moved vertically relative to the third cutting mounting structure by the second cutting unit lifting mechanism. The two third cutting units in each third cutting unit assembly can form two parallel third cutting wire saws for correspondingly cutting the two opposite ears in the stack of edge bar supported on the fourth edge bar bearing device.

[0253] The ear cutting device further includes a side skin stack unloading device for unloading the side skin stack segments cut from the ear. In some embodiments, the side skin stack unloading device may be, for example, a handling clamp or a suction cup handling robot. The side skin stack unloading device may be a stand-alone device or shared with the cutting and handling device. In some implementations, the side skin stack unloading device may be shared with the aforementioned cutting and handling device.

[0254] The ear-cutting device also includes an ear unloading device for unloading the ear. Figure 1 and Figure 10 In the embodiment shown, the ear unloading device 176 may be, for example, an ear conveyor belt. For example, an ear conveyor belt may be provided on each of the opposite sides of the fourth side skin bearing device 171.

[0255] As mentioned above, in some embodiments, the edge bar stack section to be cut is placed on the fourth edge bar support device with the cut surface facing down, bottom surface facing back and top surface facing forward (or bottom surface facing forward and top surface facing back), and the two ears located on opposite sides along the first direction. Therefore, when performing ear cutting operations using the ear cutting equipment in the edge bar assembly line system of this application, firstly, the edge bar stack section located at the cutting device is transferred to the fourth edge bar support device of the ear cutting equipment using the cutting and conveying device, and the edge bar stack section is supported by the fourth edge bar support platform and the ear support mechanisms on both sides of the fourth edge bar support device; then, the placed edge bar stack section is positioned using the fourth edge bar positioning mechanism to ensure stable placement; then, the at least one third cutting unit is driven by the cutting unit lifting mechanism. 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 bar stack section until the at least one third cutting wire saw completely exits the edge bar stack section to complete the ear cutting operation, removing the ears of each edge bar in the edge bar stack section; then, the cut ears are transferred to the ear unloading device (e.g., ear conveyor belt) using the ear support mechanism, the ears are unloaded using the ear unloading device, and the edge bar stack section unloading device unloads the edge bar stack section with the cut ears.

[0256] Subsequently, the cut-off ear flap stack segments (also known as ear flap stacks or ear flap blocks) can be further processed, such as by grinding or chamfering.

[0257] In the above embodiments, the third cutting device in the ear cutting equipment includes: a third cutting mounting structure, at least one third cutting unit, and a cutting unit lifting mechanism. The cutting unit lifting mechanism drives at least one third cutting unit to move vertically up and down to perform ear cutting on the edge leather bar stack segment. However, this is not a limitation, and the ear cutting equipment can still be modified in other ways. For example, in some embodiments, the third cutting device may include: a third cutting mounting structure, at least one third cutting unit, and a cutting unit translation mechanism. The cutting unit translation mechanism drives at least one third cutting unit to translate to perform ear cutting on the edge leather bar stack segment. Alternatively, in some embodiments, the fourth edge leather support device is a movable design, that is, the fourth edge leather support device may be equipped with a support device translation mechanism for driving the fourth edge leather support device to translate relative to the third cutting device.

[0258] The edge strip processing system disclosed in this application includes an arc-top cutting device, a stacking device, a cutting device, and an ear-shaped cutting device. The arc-top cutting device cuts the edge strip to remove the arc-top of the edge strip. The stacking device stacks multiple edge strips with the arc-top removed to form an edge strip stack. The cutting device cuts the edge strip stack to form multiple edge strip stack segments. The ear-shaped cutting device cuts the ear-shaped segments of the edge strip stack to remove the ears of each edge strip in the stack segments. Thus, the edge strip with an arc-shaped cross-section can be cut and processed to have a rectangular cross-section. Through the continuous processing, the processing efficiency of edge strips is improved and their reuse is enhanced, saving resources and costs.

[0259] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
