Description

Technical Field

[0001] The present application relates to the technical field of silicon workpiece processing, and in particular to an edge skin block grinding device. Background Art

[0002] At present, with the society's emphasis on and openness to the use of green renewable energy, the photovoltaic solar power generation field has been increasingly valued and developed. In the field of photovoltaic power generation, the usual crystalline silicon solar cells are made on high-quality silicon wafers, which are cut from pulled or cast silicon ingots by multi-wire saws and subsequently processed.

[0003] The production of silicon wafers involves squaring silicon rods (silicon rods are generally cylindrical) to form square silicon rods with rectangular cross-sections. In addition to forming square silicon rods, the edge skin material with an arched cross-section will also be cut during the squaring process. In order to make full use of this part of the edge skin material, the edge skin material can also be cut and squared (for example, cut first and then squared or squared first and then cut, etc.). In the existing process, the edge skin material can only be cut and squared in a single piece (strip, sheet), which is inefficient and cannot improve production capacity. In addition, the single piece (strip, sheet) operation is difficult during the operation process and is very likely to cause damage such as edge collapse and cracking. The finished product (which can be called edge skin sheet or edge skin strip, etc.) has different overall flatness and poor consistency, which affects product quality. Summary of the invention

[0013] The following is an explanation of the implementation of the present application by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification.

[0014] Generally, most of the existing silicon rods are cylindrical structures. The silicon rods are squared and cut by silicon rod squaring equipment, so that the cross-section of the silicon rod after squaring is rectangular (including square), and the squared silicon rod is rectangular (also cube-like) as a whole. The rectangular includes a rectangle with adjacent sides orthogonal or an angle range within a predetermined angle, a rectangle with rounded corners between adjacent sides, a rectangle with connecting short sides between adjacent sides, etc.

[0015] Taking a single crystal silicon rod as an example, in some related technologies, the process of forming a single crystal silicon rod may include: first using a silicon rod cutter to cut the original long silicon rod to form multiple short silicon rods; after the cutting is completed, using a silicon rod squarer to square the short silicon rod to form a single crystal silicon rod with a rectangular cross section. Among them, the specific implementation method of using a silicon rod cutter to cut the original long silicon rod to form multiple short silicon rods can refer to patent disclosures such as CN105856445A and CN105946127A, and the specific implementation method of using a silicon rod squarer to square the short silicon rod to form a single crystal silicon rod with a rectangular cross section can refer to patent disclosures such as CN105818285A. However, the process for forming a single crystal silicon rod is not limited to the aforementioned technology. In an optional example, the process for forming a single crystal silicon rod may also include: first, using a full silicon rod squaring machine to square the original long silicon rod to form a long single crystal silicon rod with a rectangular cross-section; after the squaring is completed, using a silicon rod cutting machine to cut the squared long single crystal silicon rod to form a short silicon rod.

[0016] In the relevant processing technology for silicon rods, several processes such as squaring, grinding, rounding / chamfering, etc. are involved. Taking the squaring of silicon rods as an example, a round silicon rod (silicon rod is cylindrical as a whole) is squared to form a square silicon rod with a rectangular cross section. In the squaring operation, in addition to forming a square silicon rod, the edge skin material with an arched cross section is also cut. In order to make full use of this part of the edge skin material, the edge skin material can also be cut and squared (for example, cut first and then squared or squared first and then cut, etc.). In the existing process, the cutting and squaring of the edge skin material can only be carried out in a single piece (strip, sheet), which is inefficient and the production capacity cannot be improved. In addition, the single piece (strip, sheet) operation is difficult during the operation, which is very easy to cause damage such as edge collapse and cracking. The finished product (which can be called edge skin sheet or edge skin strip, etc.) has different overall flatness and poor consistency, which affects the product quality.

[0017] In view of this, the present application proposes an edge leather block grinding equipment, including a machine base, a grinding device, a chamfering device and a transfer device, wherein the grinding device is used to grind the side surfaces of the edge leather block located in the grinding area, and the chamfering device is used to chamfer the edges of the edge leather block located in the chamfering area, thereby realizing the integrated operation of multiple processes such as grinding and chamfering of the edge leather block, thereby improving production efficiency and the quality of product processing operations.

[0018] In the embodiments provided in the present application, in order to clarify the definition of direction and the operation mode between different structures, a three-dimensional space defined by a first direction, a second direction, and a third direction is defined. The first direction, the second direction, and the third direction are all straight directions and are perpendicular to each other. The first direction and the second direction can form a horizontal plane, and the third direction is an upright direction perpendicular to the horizontal plane, which can also be called a vertical direction, a weight line direction, an up and down direction, or a lifting direction.

[0019] In any embodiment provided in the present application, the edge skin block is formed by stacking a plurality of edge skin strips with rectangular cross sections, wherein the edge skin strips are formed by cutting edge skin materials, and the edge skin materials are formed by squaring a round silicon rod. The edge skin material includes a rectangular bottom surface and an inferior arc surface opposite to the bottom surface, and its cross section is generally arched, that is, the edge skin material includes an arc top and sharp corners located on both sides of the arc top. The cutting operation of the edge skin material includes cutting and removing the arc top and sharp angle of the edge skin material along the length direction of the edge skin material (for example, first cutting and removing the arc top and then cutting and removing the sharp corner, or first cutting and removing the sharp corner and then cutting and removing the arc top, or simultaneously cutting and removing the arc top and the sharp corner, etc.), so as to form a flat edge skin strip (with a rectangular cross section), and subsequently, the edge skin strip is cut to form multiple edge skin strips of shorter length, and multiple edge skin strips of the same or similar length are stacked and bonded to form an edge skin block. However, this is not a limitation. In some embodiments, the edge skin block can be formed by other processes, for example, first cutting the edge skin material to remove the arc top and the sharp corner to form an edge skin strip, stacking and bonding multiple edge skin strips to form an edge skin block, and cutting the edge skin block to form multiple edge skin blocks of shorter lengths. And so on.

[0020] The edge skin block is in the shape of a rectangular parallelepiped as a whole, having two end faces, four side faces and four edges between the two end faces. The edges may be, for example, corner edges or edge connecting faces. The edge skin block equipment disclosed in the present application is used to grind the four side faces of the edge skin block and chamfer the four edges.

[0021] The following is a detailed description of the edge leather block grinding device of the present application. The present application discloses an edge leather block grinding device, comprising: a machine base, a surface grinding device, a chamfering device, and a transfer device.

[0022] The machine base serves as the main component of the edge leather block grinding equipment and is used to provide a processing platform. In practical applications, the machine base is relatively large in size and weight to provide a large mounting surface and a firm overall stability. It should be understood that the machine base can be used as a seat for different structures or components that perform processing operations in the edge leather block grinding equipment, and the specific structure of the machine base can be changed based on different functional requirements or structural requirements. In some examples, the machine base includes a fixed structure or a limiting structure such as a base, a column, a frame, etc. for receiving different components in the edge leather block grinding equipment, which are all the machine bases described in this application. In some examples, the machine base can be an integrated base, and in some examples, the machine base can include multiple independent bases.

[0023] The machine base has a processing platform, and the processing platform can be divided into multiple functional areas according to the specific operation content of the edge leather block processing operation. For example, in some embodiments, the processing platform includes a grinding area and a chamfering area. In some embodiments, the processing platform includes a loading area, a grinding area, a chamfering area, and an unloading area. In some embodiments, the processing platform includes a loading and unloading area, a grinding area, and a chamfering area. It should be noted that in each example provided in the present application, the functional area is defined by the travel path and range of the processing device at the functional area. For example, the grinding device of the edge leather block grinding equipment is located at the grinding area, and the range of the grinding area is the range occupied by the grinding device in the process of completing the grinding operation; similarly, the chamfering device of the edge leather block grinding equipment is located at the chamfering area, and the range of the chamfering area is the range occupied by the chamfering device in the process of completing the chamfering operation. The shape of the processing platform can be determined according to the machine base, or it can be determined jointly according to the processing needs of the machine base and the grinding device and the chamfering device.

[0024] In certain embodiments, each functional area is arranged along a first direction or along a second direction, wherein, in the following description, the first direction refers to the length direction of the edge leather block grinding equipment, and the second direction is perpendicular to the first direction and refers to the width direction of the edge leather block grinding equipment. For example, when the edge leather block grinding equipment includes a grinding area and a chamfering area, the grinding area and the chamfering area can be arranged in parallel along the first direction or arranged in sequence along the second direction. Taking the arrangement in parallel along the first direction as an example, when the edge leather block grinding equipment includes a loading and unloading area, a grinding area, and a chamfering area, the loading and unloading area, the grinding area, and the chamfering area can be arranged in parallel along the first direction (for example, in the form of a loading and unloading area, a grinding area, and a chamfering area, or in the form of a grinding area, a loading and unloading area, and a chamfering area, etc.). When the edge leather block grinding equipment includes a loading position, a grinding position, a chamfering position, and an unloading position, the loading position, the grinding position, the chamfering position, and the unloading position are arranged in parallel along a first direction (for example, in the form of a loading position, a grinding position, a chamfering position, and an unloading position, or in the form of a grinding position, a loading position, an unloading position, and a chamfering position, etc.).

[0025] In some embodiments, the processing platform is provided with a grinding area and a chamfering area, the grinding area is provided with a grinding device, and the chamfering area is provided with a chamfering device.

[0026] The grinding device is arranged at the grinding area of ​​the processing platform and is used to grind the side surfaces of the edge leather block located at the grinding area. The edge leather block has four side surfaces, so the grinding device is used to grind the four side surfaces of the edge leather block.

[0027] In the present application, the edge leather block is placed horizontally at the grinding area of ​​the processing platform. In order to ensure that the edge leather block can be stably placed at the grinding area, the edge leather block grinding device of the present application includes a first edge leather block clamping device.

[0028] The first edge leather block clamping device is arranged at the grinding surface area and is used to clamp the end of the edge leather block along the length direction. The first edge leather block clamping device is intended to clamp the edge leather block.

[0029] In some embodiments, the first edge skin block clamping device includes: a first load-bearing mounting seat and a first edge skin block clamp.

[0030] The first bearing mounting seat is arranged on the machine base. In some embodiments, the first bearing mounting seat is arranged on the machine base along the second direction, and is used to set the first edge leather block clamp.

[0031] The first edge leather block clamp is used to clamp the edge leather block. In some embodiments, the first edge leather block clamp may include a first clamping seat, at least one pair of first clamping members, and a first clamping member driving mechanism, wherein the at least one pair of first clamping members is provided with a first clamping portion and a first clamping portion rotating mechanism.

[0032] The at least one pair of first clamping members are arranged on opposite sides of the first clamping seat and arranged along the second direction. The at least one pair of first clamping members are controlled by the first clamping member driving mechanism to clamp the two end surfaces of the edge leather block so that the clamped edge leather block is placed horizontally along the second direction.

[0033] The first clamping member driving mechanism is used to drive at least one of the at least one pair of first clamping members to move along the second direction to adjust the clamping distance between the pair of first clamping members. In some embodiments, two first clamping members of the pair of first clamping members are arranged opposite to each other along the second direction, and the first clamping member driving mechanism can drive at least one of the pair of first clamping members to move along the second direction to adjust the clamping distance between the pair of first clamping members arranged opposite to each other.

[0034] In some embodiments, the first clamping member driving mechanism may include: an opening and closing guide rod and an opening and closing driving unit, wherein the opening and closing guide rod is arranged on the clamping seat along the second direction, and is used to set a pair of first clamping members, and the opening and closing driving unit is used to drive two first clamping members in the pair of first clamping members to move toward or away from each other along the opening and closing guide rod arranged in the second direction. In order to ensure the stability of the first clamping member being able to move horizontally along the second direction, the number of the opening and closing guide rods may be multiple, for example, there are two opening and closing guide rods. Of course, the opening and closing guide rods may also be other numbers, for example, three, five, six, or more. Taking three as an example, the three opening and closing guide rods may be arranged in the form of an isosceles triangle or an equilateral triangle.

[0035] In some embodiments, the opening and closing drive unit includes a horizontal telescopic rod and a telescopic cylinder, one end of the horizontal telescopic rod is associated with a first clamping member, and the other end of the horizontal telescopic rod is associated with the telescopic cylinder, and the telescopic cylinder is disposed on the first clamping seat. In practical applications, the telescopic cylinder can drive the horizontal telescopic rod to extend and retract. For example, the telescopic cylinder drives the horizontal telescopic rod to retract inward, drives one of the pair of first clamping members to move toward the other first clamping member along the opening and closing guide rod disposed in the second direction, or drives two of the pair of first clamping members to move toward each other along the opening and closing guide rod disposed in the second direction, thereby reducing the clamping distance between the two first clamping members, so as to clamp the edge leather block located between the two first clamping members. Correspondingly, the telescopic cylinder can drive the horizontal telescopic rod to extend outward, drive one of the pair of first clamping members to move away from the other first clamping member along the opening and closing guide rod arranged in the second direction, or drive two of the pair of first clamping members to move away from each other along the opening and closing guide rod arranged in the second direction, thereby increasing the clamping distance between the two first clamping members to release the clamped edge leather block. The telescopic cylinder can also be a telescopic oil cylinder.

[0036] In some embodiments, the opening and closing drive unit includes a screw and an opening and closing motor, one end of the screw (for example, a threaded end) is associated with a first clamping member, and the other end of the screw is associated with the opening and closing motor, and the opening and closing motor is disposed on the first clamping seat. In practical applications, the opening and closing motor can drive the screw to rotate. For example, the opening and closing motor drives the screw to rotate in the forward direction (or drives the screw to rotate in the reverse direction), drives one of the pair of first clamping members to move toward the other first clamping member along the opening and closing guide rod disposed in the second direction, or drives two of the pair of first clamping members to move toward each other along the opening and closing guide rod disposed in the second direction, thereby reducing the clamping distance between the two first clamping members, so as to clamp the edge leather block located between the two first clamping members. Correspondingly, the opening and closing motor drives the screw rod to rotate in the opposite direction (or drives the screw rod to rotate in the forward direction), drives one of the pair of first clamping members to move along the opening and closing guide rod set in the second direction away from the other first clamping member, or drives two of the pair of first clamping members to move along the opening and closing guide rod set in the second direction away from each other, thereby increasing the clamping distance between the two first clamping members to release the clamped edge leather block.

[0037] In some embodiments, the opening and closing drive unit includes a bidirectional screw and an opening and closing motor, wherein the bidirectional screw is arranged along the second direction, and the bidirectional screw is a left-handed screw, and two sections of threads are arranged on the rod body, and the rotation directions of the two sections of threads are opposite, that is, one section of thread is a left-handed thread, and the other section of thread is a right-handed thread, wherein one section of thread can be associated with a first clamping member and the other section of thread can be associated with another first clamping member (for example, the left-handed thread is associated with the first first clamping member and the right-handed thread is associated with the second first clamping member, or the right-handed thread is associated with the first first clamping member and the left-handed thread is associated with the second first clamping member), and the opening and closing motor is associated with the bidirectional screw, and is used to drive the bidirectional screw to rotate so that the two associated first clamping members move toward or away from each other along the opening and closing guide rod arranged in the second direction. In practical applications, for example, the opening and closing motor is used to drive the bidirectional screw to rotate forward (or to drive the bidirectional screw to rotate reversely), and then the two first clamping members associated therewith are driven to move toward each other (i.e., approach each other) along the opening and closing guide rod set in the second direction, and the clamping distance between the two first clamping members is reduced to clamp the edge leather block located between the two first clamping members; or, the opening and closing motor is used to drive the bidirectional screw to rotate reversely (or to drive the bidirectional screw to rotate forward), and then the two first clamping members associated therewith are driven to move away from each other (i.e., move away from each other) along the opening and closing guide rod set in the second direction, and the clamping distance between the two first clamping members is increased to release the clamped edge leather block. The opening and closing motor can be arranged in the middle section or a terminal of the bidirectional screw.

[0038] Thus, in the present application, after the end of the edge leather block along the length direction is clamped by the first edge leather block clamping device, at least one side surface to be polished can be exposed.

[0039] In some embodiments, in the first edge leather block clamping device, the first bearing mount is arranged at the bottom, the clamping seat of the first edge leather block clamp is arranged above the first bearing mount, and the at least one pair of first clamping members are arranged on the first clamping seat and are arranged upward. In some embodiments, after the at least one pair of first clamping members clamp the edge leather block, the side surface located at the top can be fully exposed, and the top side surface is used as the side surface to be ground. Therefore, the grinding device at the grinding area can include at least one grinding tool (for example, one grinding tool or two parallel grinding tools), and the grinding surface of the at least one grinding tool is horizontally facing downward. In some embodiments, after clamping the edge leather block, the at least one pair of first clamping members can fully expose the other three side surfaces except the bottom side surface adjacent to the clamping seat, that is, the top side surface and its adjacent left and right side surfaces. Therefore, the exposed three side surfaces are used as the side surfaces to be ground. Therefore, the grinding device at the grinding area may include multiple grinding tools, some of which have their grinding surfaces horizontally facing downwards, and some of which have their grinding surfaces horizontally facing left or right.

[0040] In some embodiments, in the first edge leather block clamping device, the first bearing mount is arranged at the bottom and extends upward or is arranged at the side, the first clamping seat of the first edge leather block clamp is arranged at one side of the first bearing mount, and the at least one pair of first clamping members are arranged at the first clamping seat and are arranged to the left or right. In some embodiments, after the at least one pair of first clamping members clamp the edge leather block, the side located at the far left (or far right) can be fully exposed, and the far left (or far right) side is used as the side to be ground, therefore, the grinding device at the grinding area may include at least one grinding tool (for example, one grinding tool or two parallel grinding tools), and the grinding surface of the at least one grinding tool is horizontally facing right (or horizontally facing left). In some embodiments, after clamping the edge leather block, the at least one pair of first clamping members can fully expose the other three side surfaces except the side surface located on the far right (or far left) adjacent to the clamping seat, that is, the side surface located on the far left and its adjacent upper and lower side surfaces. Therefore, the exposed three side surfaces are the side surfaces to be ground. Therefore, the grinding device at the grinding area may include multiple grinding tools, some of which have their grinding surfaces horizontally facing right, and some of which have their grinding surfaces horizontally facing downward or upward.

[0041] In the foregoing description, with respect to the side surfaces of the edge skin block that are not exposed, in certain embodiments, other auxiliary jigs (such as transfer devices, etc.) can be used to rotate or turn over the edge skin block placed on the first edge skin block clamping device to change the position of the edge skin block so as to expose the side surfaces that were not exposed originally.

[0042] In addition, in the present application, the first edge skin block clamping device may still have other changes. For example, in some embodiments, the first edge skin block clamping device includes: a first clamping portion provided on the first clamping member and a first clamping portion rotating mechanism for driving the first clamping portion of the first clamping member to rotate. The first clamping portion can be driven to rotate by the first clamping portion rotating mechanism, which can drive the edge skin block clamped between the first clamping members to rotate to adjust the position of each side surface.

[0043] In some embodiments, in the first edge leather block clamping device, the first bearing mounting seat is arranged at the bottom, the first clamping seat of the first edge leather block clamp is arranged above the first bearing mounting seat, and the at least one pair of first clamping members are arranged on the first clamping seat and are arranged upward. In some embodiments, after the at least one pair of first clamping members clamp the edge leather block, the side surface located at the top can be fully exposed, and the side surface located at the top is used as the side surface to be ground. Therefore, the grinding device at the grinding area may include at least one grinding tool (for example, one grinding tool or two parallel grinding tools), and the grinding surface of the at least one grinding tool is horizontally facing downward. After the top side surface is ground by the grinding tool and the grinding operation is completed, the first clamping part rotation mechanism is used to drive the first clamping part to rotate (for example, 90° or 180°) to drive the edge leather block to rotate (for example, 90° or 180°) to expose other side surfaces. The other exposed side surfaces can still be ground by the grinding tool. In this way, when the grinding tool does not change its position, the edge leather block is driven to rotate by the first clamping part rotating mechanism to complete the grinding operation of each side surface of the edge leather block.

[0044] In some embodiments, in the first edge leather block clamping device, the first bearing mount is arranged at the bottom and extends upward or is arranged at the side, the first clamping seat of the first edge leather block clamp is arranged at one side of the first bearing mount, and the at least one pair of first clamping members are arranged at the first clamping seat and are arranged to the left or right. In some embodiments, after the at least one pair of first clamping members clamp the edge leather block, the side located at the far left (or far right) can be fully exposed, and the far left (or far right) side is used as the side to be ground, therefore, the grinding device at the grinding area may include at least one grinding tool (for example, one grinding tool or two parallel grinding tools), and the grinding surface of the at least one grinding tool is horizontally facing right (or horizontally facing left). When the leftmost (or rightmost) side surface is ground by the grinding tool and the grinding operation is completed, the first clamping part rotation mechanism is used to drive the first clamping part to rotate (for example, 90° or 180°) to drive the edge leather block to rotate (for example, 90° or 180°) to expose other side surfaces. The other exposed side surfaces can still be ground by the grinding tool. In this way, when the grinding tool does not change its position, the first clamping part rotation mechanism drives the edge leather block to rotate, and the grinding operation of each side surface of the edge leather block is completed.

[0045] In some embodiments, the first clamping portion is a multi-point contact clamping head. It is understandable that the contact method between the multi-point contact clamping head and the end face of the edge skin block is not limited to point contact. For example, the first clamping portion has a plurality of protrusions to contact the end face of the edge skin block, wherein each protrusion can be in surface contact with the end face of the edge skin block.

[0046] In some embodiments, a pair of first clamping parts in the pair of first clamping members are configured as rigid structures for contacting the edge leather block to prevent the clamped edge leather block from being disturbed during the surface grinding operation and affecting the processing accuracy.

[0047] In practical applications, the first clamping portion rotating mechanism may include a rotatable structure provided on two first clamping portions of a pair of first clamping members and a driving source for driving at least one of the two rotatable structures to rotate.

[0048] In some embodiments of the present application, the first clamping part of the first clamping member can be configured as a rotatable truncated table, the circular plane of the truncated table contacts the end face of the edge leather block, and remains relatively still with the end face of the edge leather block after being pressed against the end face of the edge leather block. The first clamping part also includes a locking structure, and the first clamping part is in a locked state when grinding a selected plane. When switching between different grinding surfaces, the first clamping part rotates along the center of the truncated table driven by the first clamping part rotation mechanism.

[0049] In some implementations, the first clamping portion of the first clamping member includes a rotatable truncated cone and a series of protruding contacts disposed on the truncated cone, wherein each contact has a contact plane for contacting the clamped edge leather block, and the truncated cone rotates driven by the first clamping portion rotation mechanism. With regard to the contacts, in some implementations, the protruding length of the contacts, i.e., the position of the horizontal line, is adjustable, so that in the process of clamping the edge leather block, for the edge leather block with a lower end surface flatness, the protruding length of the contacts can be adjusted according to the end surface of the edge leather block, so that the contact surface of each contact is in a close contact state with the end surface of the edge leather block. The protruding length is the length of the horizontal line from the circular plane of the truncated cone to the contact plane of the contact.

[0050] The first clamping part rotation mechanism may be arranged on one of the pair of first clamping members to drive the first clamping part of the pair of first clamping members and the clamped edge leather piece to rotate; or, the first clamping part rotation mechanism may be arranged on the two first clamping members of the pair of first clamping members to coordinate movement and control the two first clamping parts of the pair of first clamping members to rotate at the same angle and direction. In some implementations, the driving source in the first clamping part rotation mechanism may be, for example, a driving motor.

[0051] Regarding the surface grinding device, the surface grinding device includes a surface grinding frame and a surface grinding unit movably arranged on the surface grinding frame or a pair of surface grinding units arranged oppositely, and each surface grinding unit has at least one surface grinding tool. In some embodiments, the edge leather block placed on the first edge leather block clamping device only exposes one side surface, or the edge leather block exposes multiple sides but only one side surface needs to be ground at a time, then the surface grinding device may include a surface grinding frame and a surface grinding unit movably arranged on the surface grinding frame, and the surface grinding unit corresponds to the exposed side surface or the side surface that needs to be ground. In some embodiments, the edge leather block placed on the first edge leather block clamping device at least exposes a pair of side surfaces arranged oppositely and both of the pair of side surfaces can be ground, then the surface grinding device may include a surface grinding frame and a pair of surface grinding units movably arranged on the surface grinding frame and arranged oppositely, and the pair of surface grinding units corresponds to the exposed pair of side surfaces.

[0052] For a certain surface grinding unit, the surface grinding unit includes a surface grinding support movably arranged on the surface grinding frame and at least one surface grinding tool arranged on the surface grinding support.

[0053] In some embodiments, the grinding surface of the grinding tool is horizontally downward (or horizontally upward), and the grinding unit includes a grinding support vertically movably arranged on a grinding frame and at least one grinding tool arranged on the grinding support, and the at least one grinding tool is used to grind the side of the edge leather block clamped by the first edge leather block clamping device.

[0054] The grinding surface support can be arranged on the grinding surface frame in the vertical direction (i.e., the third direction) through the grinding surface support lifting mechanism. The grinding surface support can be lifted and lowered relative to the grinding surface frame by using the grinding surface support lifting mechanism. In some embodiments, the grinding surface support lifting mechanism may include: a grinding surface lifting guide rail and a grinding surface lifting drive unit, wherein the grinding surface lifting guide rail is arranged on the grinding surface frame in the vertical direction, and the grinding surface lifting drive unit is used to drive the grinding surface support and at least one grinding surface tool arranged thereon to move up and down along the grinding surface lifting guide rail. In some embodiments, the grinding surface lifting drive unit may include a grinding surface lifting screw and a driving source, wherein the grinding surface lifting screw is arranged in the vertical direction and is associated with the grinding surface support, and the driving source is used to drive the grinding surface lifting screw to rotate so that the associated grinding surface support and at least one grinding surface tool arranged thereon move up and down along the grinding surface lifting guide rail. In some examples, the driving source may be, for example, a driving motor.

The driving source is associated with the driving wheel and is used to drive the driving wheel to rotate so that the associated grinding surface support and at least one grinding tool arranged thereon are moved up and down along the grinding surface lifting guide rail. In some examples, the driving source may be, for example, a driving motor.

[0056] The grinding surface support can be arranged on the grinding surface frame horizontally (for example, in the first direction) through the grinding surface support advance and retreat mechanism.

In some examples, the driving source may be, for example, a driving motor. In some embodiments, the grinding surface support advance and retreat mechanism may include: a grinding surface advance and retreat rack, a driving gear and a driving source, wherein the grinding surface advance and retreat rack is horizontally arranged on the grinding surface frame and is parallel to the grinding surface advance and retreat guide rail. The driving gear is arranged on the grinding surface support (for example, the bottom of the grinding surface support) and is meshed with the grinding surface advance and retreat rack. The driving source is associated with the driving wheel and is used to drive the driving wheel to rotate so that the associated grinding surface support and at least one grinding tool arranged thereon move forward and backward along the grinding surface advance and retreat guide rail. In some examples, the driving source may be, for example, a driving motor.

[0057] The grinding tool includes at least one grinding wheel. For example, in some embodiments, the grinding device includes a grinding tool, the grinding tool includes a grinding wheel, and the grinding wheel is a rough grinding wheel or a fine grinding wheel. In some embodiments, the grinding device may include two grinding tools arranged along the second direction, each grinding tool includes a grinding wheel, for example, the front grinding tool includes a rough grinding wheel, and the rear grinding tool includes a fine grinding wheel. In some embodiments, the grinding device includes a grinding tool, the grinding tool includes a rough grinding wheel and a fine grinding wheel nested in each other, for example, the rough grinding wheel is nested in the fine grinding wheel, or, the fine grinding wheel is nested in the rough grinding wheel. Wherein, the abrasive grain size of the fine grinding wheel is smaller than the abrasive grain size of the rough grinding wheel, and the abrasive grain density of the fine grinding wheel is greater than the abrasive grain density of the rough grinding wheel.

[0058] When the surface grinding tool includes a rough grinding wheel and a fine grinding wheel, the surface grinding tool can be used to perform rough grinding and fine grinding on the side of the edge leather block. Therefore, at least one of the rough grinding wheel and the fine grinding wheel is provided with a telescopic driving mechanism. For example, when the rough grinding wheel is nested in the fine grinding wheel, the rough grinding wheel can be provided with a telescopic driving mechanism. When performing the rough grinding operation, the telescopic driving mechanism is used to drive the rough grinding wheel to extend and protrude from the fine grinding wheel, so that the protruding rough grinding wheel can be used to perform the rough grinding operation on the side of the edge leather block, and when performing the fine grinding operation, the telescopic driving mechanism is used to drive the rough grinding wheel to retract and be recessed in the fine grinding wheel, so that the fine grinding wheel can be used to perform the fine grinding operation on the side of the edge leather block.

[0059] Alternatively, when the rough grinding wheel is nested in the fine grinding wheel, the fine grinding wheel may be provided with a telescopic drive mechanism, and when performing rough grinding operations, the telescopic drive mechanism is utilized to drive the fine grinding wheel to retract and be recessed in the rough grinding wheel, so that the rough grinding wheel can be used to perform rough grinding operations on the side surfaces of the edge leather block, and when performing fine grinding operations, the telescopic drive mechanism is utilized to drive the fine grinding wheel to extend and protrude from the rough grinding wheel, so that the protruding fine grinding wheel can be used to perform fine grinding operations on the side surfaces of the edge leather block. For example, when the fine grinding wheel is nested in the rough grinding wheel, the rough grinding wheel may be provided with a telescopic driving mechanism. When performing rough grinding, the telescopic driving mechanism is utilized to drive the rough grinding wheel to extend and protrude from the fine grinding wheel, so that the protruding rough grinding wheel can be used to perform rough grinding on the side of the edge leather block. When performing fine grinding, the telescopic driving mechanism is utilized to drive the rough grinding wheel to retract and be recessed into the fine grinding wheel, so that the fine grinding wheel can be used to perform fine grinding on the side of the edge leather block. Alternatively, when the fine grinding wheel is nested in the rough grinding wheel, the fine grinding wheel may be provided with a telescopic drive mechanism, and when performing rough grinding operations, the telescopic drive mechanism is utilized to drive the fine grinding wheel to retract and be recessed in the rough grinding wheel, so that the rough grinding wheel can be used to perform rough grinding operations on the side surfaces of the edge leather block, and when performing fine grinding operations, the telescopic drive mechanism is utilized to drive the fine grinding wheel to extend and protrude from the rough grinding wheel, so that the protruding fine grinding wheel can be used to perform fine grinding operations on the side surfaces of the edge leather block.

[0060] In the present application, when the side surface of the edge leather block is subjected to the surface grinding operation, the surface grinding device and the first edge leather block clamping device are driven to move relative to each other in the second direction so that the surface grinding device performs the surface grinding operation on the side surface of the edge leather block clamped by the first edge leather block clamping device. Therefore, in some embodiments, the surface grinding device is a mobile surface grinding device and the first edge leather block clamping device is a fixed edge leather block clamping device. In some embodiments, the surface grinding device is a fixed surface grinding device and the first edge leather block clamping device is a mobile edge leather block clamping device. In some embodiments, the surface grinding device is a mobile surface grinding device and the first edge leather block clamping device is a mobile edge leather block clamping device.

[0061] Taking a mobile surface grinding device as an example, the surface grinding device includes a surface grinding frame travel mechanism, and the surface grinding frame and the surface grinding unit provided thereon are driven to move along the second direction by the surface grinding frame travel mechanism.

[0062] In some embodiments, the grinding frame travel mechanism includes: a grinding travel guide rail and a grinding travel drive unit, wherein the grinding travel guide rail is arranged on the machine base along the second direction, and the grinding travel drive unit is used to drive the grinding frame and the grinding unit provided thereon to move along the grinding travel guide rail.

[0063] In some embodiments, the grinding surface advancing driving unit includes a grinding surface advancing rack, a driving gear, and a driving source. The grinding surface advancing rack is arranged on the machine base along the second direction and is parallel to the grinding surface advancing guide rail. The driving gear is arranged on the grinding surface frame (for example, the bottom of the grinding surface frame) and meshes with the grinding surface advancing rack. The driving gear is driven to rotate by the driving source, and the gear teeth of the driving gear mesh with the grinding surface advancing rack. Following the movement of the grinding surface advancing rack, the grinding surface frame connected to the driving gear and the grinding surface unit provided thereon move along the grinding surface advancing guide rail. The driving source is, for example, a driving motor.

[0064] In some embodiments, the grinding surface advancing drive unit includes a grinding surface advancing screw and a driving source, wherein the grinding surface advancing screw is arranged along the second direction and is associated with the grinding surface frame, and the driving source is used to drive the grinding surface advancing screw to rotate so that the associated grinding surface frame and the grinding surface unit provided therein move along the grinding surface advancing guide rail. The driving source is, for example, a driving motor.

[0065] When the side surface of the edge leather block at the grinding area is ground by the grinding device, the grinding frame travel mechanism drives the grinding frame and the grinding unit provided thereon to move in the second direction so as to achieve relative movement with the edge leather block clamped by the first edge leather block clamping device at the grinding area so that the grinding tool in the grinding unit can grind the side surface of the edge leather block clamped by the first edge leather block clamping device at the grinding area.

[0066] Taking the movable edge skin block clamping device as an example, the first edge skin block clamping device includes a first clamping and traveling mechanism, and the first clamping and traveling mechanism is used to drive the first edge skin block clamping device and the edge skin block clamped by it to move along the second direction.

[0067] In some embodiments, the first clamping and traveling mechanism includes: a first clamping and traveling guide rail and a first clamping and traveling drive unit, wherein the first clamping and traveling guide rail is arranged on the first bearing mounting seat along the second direction, and the first clamping and traveling drive unit is used to drive the first edge skin block clamp and the edge skin block clamped therein to move along the first clamping and traveling guide rail.

[0068] In some embodiments, the first clamping and traveling driving unit includes a first clamping and traveling rack, a driving gear, and a driving source. The first clamping and traveling rack is arranged on the first bearing mounting seat along the second direction, parallel to the first clamping and traveling guide rail. The driving gear is arranged on the first side leather block clamp and meshes with the first clamping and traveling guide rail. The driving gear is driven to rotate by the driving source, and the gear teeth of the driving gear mesh with the first clamping and traveling guide rail. Following the movement of the first clamping and traveling guide rail, the first side leather block clamp connected to the driving gear and the side leather block clamped therein move along the first clamping and traveling guide rail. The driving source is, for example, a driving motor.

[0069] In some embodiments, the first clamping and traveling driving unit includes a first clamping and traveling screw and a driving source, wherein the first clamping and traveling screw is arranged along the second direction and is associated with the first side skin block clamp, and the driving source is used to drive the first clamping and traveling screw to rotate so that the associated first side skin block clamp and the side skin block clamped therein move along the first clamping and traveling guide rail. The driving source is, for example, a driving motor.

[0070] When the side of the edge leather block at the grinding area is ground using the grinding device, the first edge leather block clamp and the edge leather block it clamps are driven by the first clamping and moving mechanism to move in the second direction to achieve relative movement with the grinding unit in the grinding device so that the grinding tool in the grinding unit can grind the side of the first edge leather block clamp and the edge leather block it clamps.

[0071] The chamfering device is arranged at the chamfering area of ​​the processing platform, and is used to chamfer the edges of the edge leather block located at the chamfering area. The edge leather block has four edges, so the chamfering device is used to chamfer the four edges of the edge leather block.

[0072] In the present application, the edge skin block is placed horizontally at the chamfering area of ​​the processing platform.

[0073] In certain embodiments, the edge skin block grinding equipment of the present application includes a third edge skin block clamping device. The third edge skin block clamping device is disposed in the chamfering area, and is used to clamp the end of the edge skin block along the length direction. The third edge skin block clamping device is intended to clamp the edge skin block. In certain embodiments, the third edge skin block clamping device includes: a third bearing mounting seat and a third edge skin block clamp. In certain embodiments, the third edge skin block clamping device clamps the edge skin block so that the edge skin block is placed horizontally and its length direction is consistent with the first direction. In certain embodiments, the third edge skin block clamping device clamps the edge skin block so that the edge skin block is placed horizontally and its length direction is consistent with the second direction.

[0074] In the following description, an example is taken in which the edge skin block is horizontally placed at the chamfered area and the length direction of the edge skin block is consistent with the second direction.

[0075] The third bearing mounting seat is arranged on the machine base. In some embodiments, the third bearing mounting seat is arranged on the machine base along the second direction, and is used to set a third edge leather block clamp. The third edge leather block clamp is used to clamp the edge leather block. In some embodiments, the third edge leather block clamp may include a third clamping seat, at least one pair of third clamping members, and a third clamping member driving mechanism, and the at least one pair of third clamping members is provided with a third clamping portion and a third clamping portion rotating mechanism.

[0076] The at least one pair of third clamping members are arranged on opposite sides of the third clamping seat and arranged along the second direction. The at least one pair of third clamping members are controlled by the third clamping member driving mechanism to clamp the two end surfaces of the edge leather block so that the clamped edge leather block is placed horizontally along the second direction.

[0077] The third clamping member driving mechanism is used to drive at least one of the at least one pair of third clamping members to move along the second direction to adjust the clamping distance between the pair of third clamping members. Two third clamping members of the pair of third clamping members are arranged opposite to each other along the second direction, and the third clamping member driving mechanism can drive at least one of the pair of third clamping members to move along the second direction to adjust the clamping distance between the pair of third clamping members arranged opposite to each other.

[0078] In some embodiments, the third clamping member driving mechanism may include: an opening and closing guide rod and an opening and closing driving unit, wherein the opening and closing guide rod is arranged on the clamping seat along the second direction, and is used to set a pair of third clamping members, and the opening and closing driving unit is used to drive two third clamping members in the pair of third clamping members to move toward or away from each other along the opening and closing guide rod arranged in the second direction. In order to ensure the stability of the third clamping member being able to move horizontally along the second direction, the number of the opening and closing guide rods may be multiple, for example, there are two opening and closing guide rods. Of course, the opening and closing guide rods may also be other numbers, for example, three, five, six, or more. Taking three as an example, the three opening and closing guide rods may be arranged in the form of an isosceles triangle or an equilateral triangle.

[0079] In some embodiments, the opening and closing drive unit includes a horizontal telescopic rod and a telescopic cylinder, one end of the horizontal telescopic rod is associated with a third clamping member, and the other end of the horizontal telescopic rod is associated with the telescopic cylinder, and the telescopic cylinder is disposed on the third clamping seat. In practical applications, the telescopic cylinder can drive the horizontal telescopic rod to extend and retract. For example, the telescopic cylinder drives the horizontal telescopic rod to retract inward, drives one of the pair of third clamping members to move toward the other third clamping member along the opening and closing guide rod disposed in the second direction, or drives two of the pair of third clamping members to move toward each other along the opening and closing guide rod disposed in the second direction, thereby reducing the clamping distance between the two third clamping members, so as to clamp the edge leather block located between the two third clamping members. Correspondingly, the telescopic cylinder can drive the horizontal telescopic rod to extend outward, drive one of the pair of third clamping members to move away from the other third clamping member along the opening and closing guide rod arranged in the second direction, or drive two of the pair of third clamping members to move away from each other along the opening and closing guide rod arranged in the second direction, thereby increasing the clamping distance between the two third clamping members to release the clamped edge leather block. The telescopic cylinder can also be a telescopic oil cylinder.

[0080] In some embodiments, the opening and closing drive unit includes a screw and an opening and closing motor, one end of the screw (for example, a threaded end) is associated with a third clamping member, and the other end of the screw is associated with the opening and closing motor, and the opening and closing motor is disposed on the third clamping seat. In practical applications, the opening and closing motor can drive the screw to rotate. For example, the opening and closing motor drives the screw to rotate in the forward direction (or drives the screw to rotate in the reverse direction), drives one of the pair of third clamping members to move toward the other third clamping member along the opening and closing guide rod disposed in the second direction, or drives two of the pair of third clamping members to move toward each other along the opening and closing guide rod disposed in the second direction, thereby reducing the clamping distance between the two third clamping members, so as to clamp the edge leather block located between the two third clamping members. Correspondingly, the opening and closing motor drives the screw rod to rotate in the opposite direction (or drives the screw rod to rotate in the forward direction), drives one of the pair of third clamping members to move along the opening and closing guide rod set in the second direction away from the other third clamping member, or drives two of the pair of third clamping members to move along the opening and closing guide rod set in the second direction away from each other, thereby increasing the clamping distance between the two third clamping members to release the clamped edge leather block.

[0081] In some embodiments, the opening and closing drive unit includes a bidirectional screw and an opening and closing motor, wherein the bidirectional screw is arranged along the second direction, and the bidirectional screw is a left-handed screw, and two sections of threads are arranged on the rod body, and the rotation direction of the two sections of threads is opposite, that is, one section of thread is a left-handed thread, and the other section of thread is a right-handed thread, wherein one section of thread can be associated with a third clamping member and the other section of thread can be associated with another third clamping member (for example, the left-handed thread is associated with the first third clamping member and the right-handed thread is associated with the second third clamping member, or the right-handed thread is associated with the first third clamping member and the left-handed thread is associated with the second third clamping member), and the opening and closing motor is associated with the bidirectional screw, and is used to drive the bidirectional screw to rotate so that the two associated third clamping members move toward or away from each other along the opening and closing guide rod arranged in the second direction. In practical applications, for example, the opening and closing motor drives the bidirectional screw to rotate forward (or drives the bidirectional screw to rotate reversely), and then drives the two associated third clamping members to move toward each other (i.e., approach each other) along the opening and closing guide rod set in the second direction, and reduces the clamping distance between the two third clamping members, so as to clamp the edge leather block located between the two third clamping members; or, the opening and closing motor drives the bidirectional screw to rotate reversely (or drives the bidirectional screw to rotate forward), and then drives the two associated third clamping members to move away from each other (i.e., move away from each other) along the opening and closing guide rod set in the second direction, and increases the clamping distance between the two third clamping members, so as to release the clamped edge leather block. The opening and closing motor can be arranged in the middle section or a terminal of the bidirectional screw.

[0082] Thus, in the present application, after the end of the edge leather block along the length direction is clamped by the third edge leather block clamping device, at least one edge portion to be chamfered can be exposed.

[0083] In some embodiments, in the third edge leather block clamping device, the third bearing mount is arranged at the bottom, the clamping seat of the third edge leather block clamp is arranged above the third bearing mount, and the at least one pair of third clamping members are arranged on the third clamping seat and are arranged upward. In some embodiments, after the at least one pair of third clamping members clamp the edge leather block, the uppermost edge portion can be fully exposed, and the uppermost edge portion is used as the edge portion to be chamfered. Therefore, the chamfering device at the chamfering position may include at least one chamfering grinder (for example, a chamfering grinder or two parallel chamfering grinders), and the chamfering surface of the at least one chamfering grinder is horizontally facing downward. In some embodiments, after the at least one pair of third clamping members clamp the edge leather block, the two left and right edges arranged above can be fully exposed (at this time, the side surface of the edge leather block is arranged horizontally or vertically), that is, the two exposed edges are used as the edges to be chamfered. Therefore, the chamfering device at the chamfering position may include a pair of chamfering grinders arranged at an angle. For example, in one example, one of the pair of chamfering grinders is at an angle of 45° to the horizontal or vertical, and the other of the pair of chamfering grinders is at an angle of 45° to the horizontal or vertical. Of course, the above-mentioned angles are not limited to this, and in different embodiments, other angles can be selected, for example, the inclination angle can be any angle between 40° and 60°, and is not limited to integer degrees.

[0084] In some embodiments, in the third edge leather block clamping device, the third bearing mount is arranged at the bottom and extends upward or is arranged at the side, the third clamping seat of the third edge leather block clamp is arranged at one side of the third bearing mount, and the at least one pair of third clamping members are arranged at the third clamping seat and are arranged to the left or right. In some embodiments, after the at least one pair of third clamping members clamp the edge leather block, the edge located on the far left (or far right) can be fully exposed, and the edge on the far left (or far right) is used as the edge to be chamfered. Therefore, the chamfering device at the chamfering position may include at least one chamfering grinder (for example, one chamfering grinder or two parallel chamfering grinders), and the chamfering surface of the at least one chamfering grinder is horizontally facing right (or horizontally facing left). In certain embodiments, after the at least one pair of third clamping members clamp the edge leather block, the two upper and lower edges located on the left side (or right side) can be fully exposed (in this case, the side surface of the edge leather block is arranged horizontally or vertically), that is, the two exposed edges are used as the edges to be chamfered, so the chamfering device at the chamfering position may include a pair of chamfering grinders arranged at an angle. For example, in a certain example, one of the pair of chamfering grinders is at a 45° angle to the horizontal line or the vertical, and the other chamfering grinder in the pair of chamfering grinders is at a 45° angle to the horizontal line or the vertical. Of course, the above-mentioned angle is not limited to this, and in different embodiments, other angles can be selected, for example, the inclination angle can be any angle from 40° to 60°, and is not limited to integer degrees.

[0085] In the foregoing description, with respect to the unexposed edges of the edge skin block, in certain embodiments, other auxiliary fixtures (such as a transfer device, etc.) can be used to rotate or turn over the edge skin block placed on the third edge skin block clamping device to change the position of the edge skin block so as to expose the previously unexposed edges.

[0086] In addition, in the present application, the third edge leather block clamping device may still have other changes. For example, in some embodiments, the third edge leather block clamping device includes: a third clamping portion provided on the third clamping piece and a third clamping portion rotating mechanism for driving the third clamping portion of the third clamping piece to rotate. The third clamping portion can be driven to rotate by the third clamping portion rotating mechanism, which can drive the edge leather block clamped between the third clamping pieces to rotate so as to adjust the position of each edge.

[0087] In some embodiments, in the third edge leather block clamping device, the third bearing mount is arranged at the bottom, the third clamping seat of the third edge leather block clamp is arranged above the third bearing mount, and the at least one pair of third clamping members are arranged on the third clamping seat and arranged upward. After the at least one pair of third clamping members clamp the edge leather block, the uppermost edge portion can be fully exposed, and the uppermost edge portion is used as the edge portion to be chamfered. Therefore, the chamfering device at the chamfering position may include at least one chamfering grinder (for example, a chamfering grinder or two parallel chamfering grinders), and the chamfering surface of the at least one chamfering grinder is horizontally facing downward. After the uppermost edge portion is chamfered by the chamfering grinder and completed, the third clamping member is driven to rotate by the third clamping member rotation mechanism to drive the edge leather block to rotate to expose other edges. The other exposed edges can still be chamfered by the chamfering grinder. In this way, when the chamfering grinder does not change its position, the edge leather block is driven to rotate by the third clamping part rotating mechanism to complete the chamfering operation of each edge portion of the edge leather block.

[0088] In some embodiments, in the third edge leather block clamping device, the third bearing mount is arranged at the bottom and extends upward or is arranged at the side, the third clamping seat of the third edge leather block clamp is arranged at one side of the third bearing mount, and the at least one pair of third clamping members are arranged at the third clamping seat and are arranged to the left or right. After the at least one pair of third clamping members clamp the edge leather block, the edge portion located at the far left (or far right) can be fully exposed, and the edge portion located at the far left (or far right) is used as the edge portion to be chamfered. Therefore, the chamfering device at the chamfering position may include at least one chamfering grinder (for example, a chamfering grinder or two parallel chamfering grinders), and the chamfering surface of the at least one chamfering grinder is horizontally facing right (or horizontally facing left). After the leftmost (or far right) edge portion is chamfered by the chamfering grinder and completed, the third clamping portion can be driven to rotate by the third clamping portion rotation mechanism to drive the third clamping portion to rotate, so as to expose other edges. The other exposed edges can still be chamfered by the chamfering tool. In this way, when the chamfering tool does not change its position, the edge leather block is driven to rotate by the third clamping part rotating mechanism to complete the chamfering of each edge of the edge leather block.

[0089] In some embodiments, the third clamping portion is a multi-point contact clamping head. It is understandable that the contact method between the multi-point contact clamping head and the end face of the edge skin block is not limited to point contact. For example, the third clamping portion has a plurality of protrusions to contact the end face of the edge skin block, wherein each protrusion can be in surface contact with the end face of the edge skin block.

[0090] In some embodiments, a portion of a pair of third clamping parts in the pair of third clamping members for contacting the edge skin block is configured as a rigid structure to prevent the clamped edge skin block from being disturbed during the chamfering operation and affecting the processing accuracy.

[0091] In practical applications, the third clamping portion rotating mechanism may include a rotatable structure provided on two third clamping portions of a pair of third clamping members and a driving source for driving at least one of the two rotatable structures to rotate.

[0092] In some embodiments of the present application, the third clamping part of the third clamping member can be configured as a rotatable truncated cone, the circular plane of the truncated cone contacts the end face of the edge leather block, and remains relatively still with the end face of the edge leather block after being pressed against the end face of the edge leather block. The third clamping part also includes a locking structure, and the third clamping part is in a locked state when chamfering a selected plane. When switching between different chamfers, the third clamping part rotates along the center of the truncated cone driven by the third clamping part rotation mechanism.

[0093] In some implementations, the third clamping portion of the third clamping member includes a rotatable truncated cone and a series of protruding contacts arranged on the truncated cone, wherein each contact has a contact plane for contacting the clamped edge leather block, and the truncated cone rotates driven by the rotation mechanism of the third clamping portion. Regarding the contacts, in some implementations, the protruding length of the contacts, that is, the position of the horizontal line, is adjustable, so that in the process of clamping the edge leather block, for the edge leather block with a lower end surface flatness, the protruding length of the contacts can be adjusted according to the end surface of the edge leather block, so that the contact surface of each contact is in a close contact state with the end surface of the edge leather block. The protruding length is the length of the horizontal line from the circular plane of the truncated cone to the contact plane of the contact.

[0094] The third clamping part rotation mechanism may be arranged on one of the third clamping parts in a pair of third clamping parts, so as to drive the third clamping part of the third clamping parts and the clamped edge leather piece to rotate; or, the third clamping part rotation mechanism may be arranged on two third clamping parts in a pair of third clamping parts, and coordinately control the two third clamping parts of the third clamping parts to rotate at the same angle and direction. The driving source in the third clamping part rotation mechanism may be, for example, a driving motor.

[0095] Regarding the chamfering device, the chamfering device includes a chamfering frame and a chamfering unit movably arranged on the chamfering frame or a pair of chamfering units arranged opposite to each other, and each chamfering unit has at least one chamfering grinder. In some embodiments, the edge skin block placed on the third edge skin block clamping device only reveals one edge portion, or the edge skin block reveals multiple edges but only one edge portion needs to be chamfered at a time, then the chamfering device may include a chamfering frame and a chamfering unit movably arranged on the chamfering frame, and the chamfering unit corresponds to the exposed edge portion or the edge portion that needs to be chamfered. In some embodiments, the edge skin block placed on the third edge skin block clamping device at least reveals a pair of edges (that is, two edges adjacent to a certain side surface) and both of the pair of edges can be chamfered, then the chamfering device may include a chamfering frame and a pair of chamfering units movably arranged on the chamfering frame at an angle, and the pair of chamfering units corresponds to the exposed pair of edges.

[0096] For a certain chamfering unit, the chamfering unit includes a chamfering support movably arranged on the chamfering frame and at least one chamfering grinding tool arranged on the chamfering support.

[0097] In some embodiments, the chamfering surface of the chamfering grinder is horizontally downward or horizontally upward (if it is a pair of chamfering grinders, the chamfering grinder is angled downward or angled upward), and the chamfering unit includes a chamfering support vertically movably arranged on the chamfering frame and at least one chamfering grinder arranged on the chamfering support, and the at least one chamfering grinder is used to chamfer the edges of the edge skin block clamped by the third edge skin block clamping device.

[0098] The chamfer support can be arranged on the chamfer frame in the vertical direction (i.e., the third direction) through the chamfer support lifting mechanism. The chamfer support can be lifted and lowered relative to the chamfer frame by using the chamfer support lifting mechanism. In some embodiments, the chamfer support lifting mechanism may include: a chamfer lifting guide rail and a chamfer lifting drive unit, wherein the chamfer lifting guide rail is arranged on the chamfer frame in the vertical direction, and the chamfer lifting drive unit is used to drive the chamfer support and at least one chamfering tool arranged thereon to move up and down along the chamfer lifting guide rail. In some embodiments, the chamfer lifting drive unit may include a chamfer lifting screw rod and a driving source, wherein the chamfer lifting screw rod is arranged in the vertical direction and is associated with the chamfer support, and the driving source is used to drive the chamfer lifting screw rod to rotate so that the associated chamfer support and at least one chamfering tool arranged thereon can move up and down along the chamfer lifting guide rail. In some examples, the driving source may be, for example, a driving motor. In some embodiments, the chamfer support lifting mechanism may include: a chamfer lifting rack, a driving gear, and a driving source, wherein the chamfer lifting rack is vertically arranged on the chamfering frame and is parallel to the chamfer lifting guide rail. The driving gear is arranged on the chamfer support (e.g., the bottom of the chamfer support) and is meshed with the chamfer lifting rack. The driving source is associated with the driving wheel and is used to drive the driving wheel to rotate so that the associated chamfer support and at least one chamfering tool arranged thereon are moved up and down along the chamfer lifting guide rail. In some examples, the driving source may be, for example, a driving motor.

[0099] In some embodiments, the chamfering surface of the chamfering grinder is vertically facing left or vertically facing right (if it is a pair of chamfering grinders, the chamfering surface of the chamfering grinder is angled to the left or to the right), then the chamfering unit includes a chamfering support horizontally movably arranged on the chamfering frame and at least one chamfering grinder arranged on the chamfering support, and the at least one chamfering grinder is used to chamfer the edges of the edge skin block clamped by the third edge skin block clamping device.

[0100] The chamfer support can be arranged on the chamfer frame horizontally (for example, in the first direction) through a chamfer support advance and retreat mechanism. The chamfer support can move forward and backward relative to the chamfer frame by using the chamfer support advance and retreat mechanism. In some embodiments, the chamfer support advance and retreat mechanism may include: a chamfer advance and retreat guide rail and a chamfer advance and retreat drive unit, wherein the chamfer advance and retreat guide rail is arranged horizontally on the chamfer frame, and the chamfer advance and retreat drive unit is used to drive the chamfer support and at least one chamfering tool arranged thereon to move forward and backward along the chamfer advance and retreat guide rail. In some embodiments, the chamfer advance and retreat drive unit may include a chamfer lifting screw and a drive source, wherein the chamfer advance and retreat screw is arranged horizontally and associated with the chamfer support, and the drive source is used to drive the chamfer advance and retreat screw to rotate so that the associated chamfer support and at least one chamfering tool arranged thereon move forward and backward along the chamfer advance and retreat guide rail.

Therefore, at least one of the rough grinding wheel and the fine grinding wheel is provided with a telescopic driving mechanism. For example, when the rough grinding wheel is nested in the fine grinding wheel, the rough grinding wheel can be provided with a telescopic driving mechanism. When performing the rough grinding operation, the telescopic driving mechanism is used to drive the rough grinding wheel to extend and protrude from the fine grinding wheel, so that the protruding rough grinding wheel can be used to perform the rough grinding operation on the edge of the edge leather block. When performing the fine grinding operation, the telescopic driving mechanism is used to drive the rough grinding wheel to retract and be recessed in the fine grinding wheel, so that the fine grinding wheel can be used to perform the fine grinding operation on the edge of the edge leather block.

[0104] Alternatively, when the rough grinding wheel is nested in the fine grinding wheel, the fine grinding wheel may be provided with a telescopic drive mechanism, and when performing rough grinding, the telescopic drive mechanism is utilized to drive the fine grinding wheel to retract and be recessed in the rough grinding wheel, so that the rough grinding wheel can be used to perform rough grinding on the edges of the edge leather block, and when performing fine grinding, the telescopic drive mechanism is utilized to drive the fine grinding wheel to extend and protrude from the rough grinding wheel, so that the protruding fine grinding wheel can be used to perform fine grinding on the edges of the edge leather block. For example, when the fine grinding wheel is nested in the rough grinding wheel, the rough grinding wheel may be provided with a telescopic driving mechanism. When performing rough grinding, the telescopic driving mechanism is utilized to drive the rough grinding wheel to extend and protrude from the fine grinding wheel, so that the protruding rough grinding wheel can be used to perform rough grinding on the edges of the edge leather block. When performing fine grinding, the telescopic driving mechanism is utilized to drive the rough grinding wheel to retract and be recessed in the fine grinding wheel, so that the fine grinding wheel can be used to perform fine grinding on the edges of the edge leather block. Alternatively, when the fine grinding wheel is nested in the rough grinding wheel, the fine grinding wheel may be provided with a telescopic drive mechanism, and when performing rough grinding, the telescopic drive mechanism is utilized to drive the fine grinding wheel to contract and be recessed in the rough grinding wheel, so that the rough grinding wheel can be used to perform rough grinding on the edges of the edge leather block, and when performing fine grinding, the telescopic drive mechanism is utilized to drive the fine grinding wheel to extend and protrude from the rough grinding wheel, so that the protruding fine grinding wheel can be used to perform fine grinding on the edges of the edge leather block.

[0105] In the present application, when the edge of the side leather block is chamfered, the chamfering device and the third side leather block clamping device are driven to move relative to each other in the second direction so that the chamfering device chamfers the edge of the side leather block clamped by the third side leather block clamping device. Therefore, in some embodiments, the chamfering device is a mobile chamfering device and the third side leather block clamping device is a fixed side leather block clamping device. In some embodiments, the chamfering device is a fixed chamfering device and the third side leather block clamping device is a mobile side leather block clamping device. In some embodiments, the chamfering device is a mobile chamfering device and the third side leather block clamping device is a mobile side leather block clamping device.

[0106] Taking the mobile chamfering device as an example, the chamfering device includes a chamfering frame travel mechanism, and the chamfering frame and the chamfering unit provided thereon are driven to move along the second direction by the chamfering frame travel mechanism.

[0107] In some embodiments, the chamfering frame travel mechanism includes: a chamfering travel guide rail and a chamfering travel drive unit, wherein the chamfering travel guide rail is arranged on the machine base along the second direction, and the chamfering travel drive unit is used to drive the chamfering frame and the chamfering unit thereon to move along the chamfering travel guide rail.

[0108] In some embodiments, the chamfering driving unit includes a chamfering rack, a driving gear, and a driving source. The chamfering rack is arranged on the base along the second direction and is parallel to the chamfering guide rail. The driving gear is arranged on the chamfering frame (for example, the bottom of the chamfering frame) and meshes with the chamfering rack. The driving gear is driven to rotate by the driving source, and the gear teeth of the driving gear mesh with the chamfering rack. Following the movement of the chamfering rack, the chamfering frame connected to the driving gear and the chamfering unit provided thereon move along the chamfering guide rail. The driving source is, for example, a driving motor.

[0109] In some embodiments, the chamfering driving unit includes a chamfering driving screw and a driving source, wherein the chamfering driving screw is arranged along the second direction and is associated with the chamfering frame, and the driving source is used to drive the chamfering driving screw to rotate so that the associated chamfering frame and the chamfering unit provided therein move along the chamfering driving guide rail. The driving source is, for example, a driving motor.

[0110] When the chamfering device is used to chamfer the edges of the side skin block at the chamfering area, the chamfering frame and its chamfering unit are driven by the chamfering frame travel mechanism to move in the second direction to achieve relative movement with the side skin block clamped by the third side skin block clamping device at the chamfering area so that the chamfering grinder in the chamfering unit can chamfer the edges of the side skin block clamped by the third side skin block clamping device at the chamfering area.

[0111] Taking the movable edge skin block clamping device as an example, the third edge skin block clamping device includes a third clamping and traveling mechanism, and the third edge skin block clamping device and the edge skin block clamped by it are driven to move along the second direction by the third clamping and traveling mechanism.

[0112] In some embodiments, the third clamping and traveling mechanism includes: a third clamping and traveling guide rail and a third clamping and traveling drive unit, wherein the third clamping and traveling guide rail is arranged on a third bearing mounting seat along the second direction, and the third clamping and traveling drive unit is used to drive the third side skin block clamp and the side skin block clamped therein to move along the third clamping and traveling guide rail.

[0113] In some embodiments, the third clamping and traveling driving unit includes a third clamping and traveling rack, a driving gear, and a driving source. The third clamping and traveling rack is arranged on the third bearing mounting seat along the second direction, parallel to the third clamping and traveling guide rail. The driving gear is arranged on the third side leather block clamp and meshes with the third clamping and traveling guide rail. The driving gear is driven to rotate by the driving source, and the gear teeth of the driving gear mesh with the third clamping and traveling guide rail. Following the movement of the third clamping and traveling guide rail, the third side leather block clamp connected to the driving gear and the side leather block clamped therein move along the third clamping and traveling guide rail. The driving source is, for example, a driving motor.

[0114] In some embodiments, the third clamping and traveling driving unit includes a third clamping and traveling screw and a driving source, wherein the third clamping and traveling screw is arranged along the second direction and is associated with the third side skin block clamp, and the driving source is used to drive the third clamping and traveling screw to rotate so that the associated third side skin block clamp and the side skin block clamped therein move along the third clamping and traveling guide rail. The driving source is, for example, a driving motor.

[0115] When the chamfering device is used to chamfer the edges of the edge leather block at the chamfering area, the third edge leather block clamp and the edge leather block clamped by it are driven by the third clamping and moving mechanism to move in the second direction to achieve relative movement with the chamfering unit in the chamfering device so that the chamfering grinder in the chamfering unit can chamfer the edges of the third edge leather block clamp and the edge leather block clamped by it.

[0116] The third edge leather block clamping device and chamfering device described above may still have other variations.

[0117] The edge leather block grinding device of the present application includes an edge leather block supporting device. In some embodiments, the edge leather block supporting device supports the edge leather block so that the edge leather block is placed horizontally and its length direction is consistent with the first direction. In some embodiments, the edge leather block supporting device supports the edge leather block so that the edge leather block is placed horizontally and its length direction is consistent with the second direction.

[0118] In the following description, an example is taken in which the edge skin block is horizontally placed at the chamfered area and the length direction of the edge skin block is consistent with the second direction.

[0119] The edge skin block supporting device may include an edge skin block supporting platform, which is arranged on the machine base along the second direction and located at the chamfered area, and is used to support at least one edge skin block placed horizontally. If one edge skin block is placed horizontally on the edge skin block supporting platform as an example, the length of the edge skin block supporting platform is related to the length of the edge skin block, and the width of the edge skin block supporting platform may be related to the width of the edge skin block. If two edge skin blocks are placed horizontally on the edge skin block supporting platform in a left-right parallel manner as an example, the length of the edge skin block supporting platform matches the length of the edge skin block, and the width of the edge skin block supporting platform matches the sum of the widths of the two edge skin blocks.

[0120] In some embodiments, the edge skin block supporting device supports the edge skin block by placing the edge skin block in a manner that one side surface of the edge skin block (the side surface may be referred to as the supporting bottom surface) is in contact with the slope supporting platform, so that the edge skin block can be placed horizontally and at least the top surface opposite to the supporting bottom surface and two edges adjacent to the top surface are exposed.

[0121] In order to ensure that the edge skin block can be placed firmly on the edge skin block supporting platform, the edge skin block supporting device may further include an edge skin block positioning mechanism, which is used to position the edge skin block supported by the edge skin block supporting platform. In this way, when the edge skin block supported by the edge skin block supporting platform is subjected to surface grinding by the surface grinding device, the edge skin block positioning mechanism may be used to position the edge skin block supported by the edge skin block supporting platform, so as to avoid relative displacement between the edge skin block and the edge skin block supporting platform during the surface grinding operation, thereby affecting the surface grinding quality. In certain embodiments, the edge skin block positioning mechanism may be, for example, an edge skin clamping mechanism, which is disposed at the front and rear ends of the edge skin block supporting platform along the length direction, and is used to clamp the two ends of the edge skin block, or the edge skin clamping mechanism is disposed at the left and right sides of the edge skin block supporting platform in the relative length direction, and is used to clamp the two sides of the edge skin block.

[0122] Since the edge skin block supporting device can support the edge skin block and expose the top surface opposite to the supporting bottom surface and two edges adjacent to the top surface, the chamfering device may include a chamfering frame and at least one pair of chamfering units movably arranged on the chamfering frame, and the at least one pair of chamfering units corresponds to the exposed pair of edges. Each chamfering unit has at least one chamfering grinder.

[0123] For a certain chamfering unit, the chamfering unit includes a chamfering support movably arranged on the chamfering frame and at least one chamfering grinding tool arranged on the chamfering support.

[0124] In some embodiments, the chamfering surface of the chamfering grinder is angled downward, and the chamfering unit includes a chamfering support vertically movably arranged on a chamfering frame and at least one chamfering grinder arranged on the chamfering support, wherein the at least one chamfering grinder is used to chamfer the edges of the edge skin block supported by the edge skin block supporting device.

[0125] The chamfer support can be arranged on the chamfer frame in the vertical direction (i.e., the third direction) through the chamfer support lifting mechanism. The chamfer support can be lifted and lowered relative to the chamfer frame by using the chamfer support lifting mechanism. In some embodiments, the chamfer support lifting mechanism may include: a chamfer lifting guide rail and a chamfer lifting drive unit, wherein the chamfer lifting guide rail is arranged on the chamfer frame in the vertical direction, and the chamfer lifting drive unit is used to drive the chamfer support and at least one chamfering tool arranged thereon to move up and down along the chamfer lifting guide rail. In some embodiments, the chamfer lifting drive unit may include a chamfer lifting screw rod and a driving source, wherein the chamfer lifting screw rod is arranged in the vertical direction and is associated with the chamfer support, and the driving source is used to drive the chamfer lifting screw rod to rotate so that the associated chamfer support and at least one chamfering tool arranged thereon can move up and down along the chamfer lifting guide rail. In some examples, the driving source may be, for example, a driving motor. In some embodiments, the chamfer support lifting mechanism may include: a chamfer lifting rack, a driving gear, and a driving source, wherein the chamfer lifting rack is vertically arranged on the chamfering frame and is parallel to the chamfer lifting guide rail. The driving gear is arranged on the chamfer support (e.g., the bottom of the chamfer support) and is meshed with the chamfer lifting rack. The driving source is associated with the driving wheel and is used to drive the driving wheel to rotate so that the associated chamfer support and at least one chamfering tool arranged thereon are moved up and down along the chamfer lifting guide rail. In some examples, the driving source may be, for example, a driving motor.

[0126] In addition, the chamfering supports in the at least one pair of chamfering units may also be shared. For example, the first chamfering support in the first chamfering unit and the second chamfering support in the second chamfering unit in the pair of chamfering units may share the same chamfering support, and the shared chamfering support drives the pair of chamfers to move vertically on the chamfering frame through the chamfering support lifting mechanism.

[0127] Taking a pair of chamfering units as an example, the pair of chamfering units can be set at an angle. For example, in a certain example, the chamfering tool in the first chamfering unit is at a 45° angle to the horizontal line or the vertical direction, and the chamfering tool in the second chamfering unit is at a 45° angle to the horizontal line or the vertical direction. Of course, the above-mentioned angle is not limited to this. In different embodiments, other angles can be selected. For example, the inclination angle can be any angle between 40° and 60°, and is not limited to integer degrees.

[0128] The chamfering tool comprises at least one grinding wheel. In some embodiments, the grinding wheel is a rough grinding wheel or a fine grinding wheel. In some embodiments, the chamfering tool comprises a rough grinding wheel and a fine grinding wheel nested in each other, for example, the rough grinding wheel is nested in the fine grinding wheel, or, the fine grinding wheel is nested in the rough grinding wheel.

[0129] In the present application, when the edge of the edge leather block is chamfered, the chamfering device and the edge leather block supporting device are driven to move relative to each other in the second direction so that at least one pair of chamfering units in the chamfering device performs chamfering on two edges of the edge leather block supported by the edge leather block supporting device. Therefore, in some embodiments, the chamfering device is a mobile chamfering device and the edge leather block supporting device is a fixed edge leather block supporting device. In some embodiments, the chamfering device is a fixed chamfering device and the edge leather block supporting device is a mobile edge leather block supporting device. In some embodiments, the chamfering device is a mobile chamfering device and the edge leather block supporting device is a mobile edge leather block supporting device.

[0130] Taking the mobile chamfering device as an example, the chamfering device includes a chamfering frame travel mechanism, and the chamfering frame and at least one pair of chamfering units provided thereon are driven to move along the second direction by the chamfering frame travel mechanism.

[0132] In some embodiments, the chamfering driving unit includes a chamfering rack, a driving gear, and a driving source. The chamfering rack is arranged on the base along the second direction and is parallel to the chamfering guide rail. The driving gear is arranged on the chamfering frame (for example, the bottom of the chamfering frame) and meshes with the chamfering rack. The driving gear is driven to rotate by the driving source, and the gear teeth of the driving gear mesh with the chamfering rack. Following the movement of the chamfering rack, the chamfering frame connected to the driving gear and at least one pair of chamfering units provided thereon move along the chamfering guide rail. The driving source is, for example, a driving motor.

[0133] In some embodiments, the chamfering driving unit includes a chamfering driving screw and a driving source, wherein the chamfering driving screw is arranged along the second direction and is associated with the chamfering frame, and the driving source is used to drive the chamfering driving screw to rotate so that the associated chamfering frame and at least one pair of chamfering units provided therein move along the chamfering driving guide rail. The driving source is, for example, a driving motor.

[0134] When the chamfering device is used to chamfer the edges of the edge skin block at the chamfering position, the chamfering frame and at least one pair of chamfering units provided thereon are driven by the chamfering frame travel mechanism to move along the second direction so as to achieve relative movement with the edge skin block supported by the edge skin block supporting device at the chamfering position so that the chamfering grinding tools in at least one pair of chamfering units can chamfer the two edges of the edge skin block supported by the edge skin block supporting device at the chamfering position.

[0135] Taking the movable edge skin block supporting device as an example, the edge skin block supporting device includes a supporting and traveling mechanism, and the supporting and traveling mechanism is used to drive the edge skin block supporting device and the edge skin block supported by it to move along the second direction.

[0136] In some embodiments, the supporting and traveling mechanism includes: a supporting and traveling guide rail and a supporting and traveling drive unit, wherein the supporting and traveling guide rail is arranged on the side skin block supporting device along the second direction, and the supporting and traveling drive unit is used to drive the side skin block supporting device and the side skin block supported by it to move along the supporting and traveling guide rail.

[0137] In some embodiments, the supporting and traveling driving unit includes a supporting and traveling rack, a driving gear, and a driving source. The supporting and traveling rack is arranged on the side skin block supporting device along the second direction, parallel to the supporting and traveling guide rail.

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

[0139] When the chamfering device is used to chamfer the edges of the edge skin block at the chamfering area, the edge skin block supporting device and the edge skin block it supports are driven by the supporting travel mechanism to move in the second direction to achieve relative movement with at least one pair of chamfering units in the chamfering device so that the chamfering grinder in at least one pair of chamfering units can chamfer the two edges of the edge skin block supporting device and the edge skin block it supports.

[0140] The edge leather block grinding device of the present application may also include a cleaning device. The cleaning device may be arranged on the machine base, and is used to clean the edge leather block. The edge leather block grinding device may also include a loading and conveying device, which is arranged at the loading area, and is used to convey the edge leather block to be ground. In some embodiments, the loading and conveying device may be, for example, a conveyor belt device, including a conveyor belt, and the conveyor belt is wound around two conveyor rollers arranged opposite to each other in the front and rear, and at least one of the two conveyor rollers is connected to a loading drive source, and the loading drive source may be, for example, a servo motor.

[0141] In the edge leather block grinding device of the present application, a material unloading conveying device may also be included, which is arranged at the unloading position and is used to convey the edge leather block that has been ground.

[0142] In some embodiments, the loading conveying device and the unloading conveying device are a common structure.

[0143] The edge skin block grinding device of the present application may also include a transfer device for transferring the edge skin block between various functional areas. In some embodiments, the transfer device includes: a transfer mounting frame, a transfer fixture, a transfer lifting mechanism, and a transfer translation mechanism.

[0144] The transfer mounting frame is mounted on the machine base. In some embodiments, the various functional locations are arranged in parallel along the first direction, and the transfer mounting frame is straddled on the machine base in the first direction, and the transfer mounting frame may correspond to the entire length dimension of the machine base to cover the various functional locations within the length of the machine base. In some embodiments, the various functional locations are arranged in sequence along the second direction, and the transfer mounting frame is straddled on the machine base in the second direction, and the transfer mounting frame may correspond to the entire width dimension of the machine base to cover the various functional locations within the width of the machine base. It should be noted that the following introduction to the transfer device is described by taking the example that the various functional locations are arranged in parallel along the first direction.

[0145] The transport clamp is used to clamp the edge leather block. In some embodiments, the transport clamp may further include: a clamp seat, at least one pair of clamp arms arranged on opposite sides of the clamp seat and arranged along the second direction, and a clamp arm driving mechanism.

[0146] The at least one pair of clamping arms are arranged on the clamping seat opposite to each other along the second direction through a clamping arm driving mechanism, and are used to clamp two end surfaces of the edge leather block along the length direction, so that the clamped edge leather block is in a horizontal state.

[0147] The clamp arm driving mechanism is used to drive at least one of the at least one pair of clamp arms to move along a horizontal line to adjust the clamping distance between the pair of clamp arms. In some embodiments, two clamp arms in the pair of clamp arms are arranged opposite to each other along a second direction, and the clamp arm driving mechanism can drive at least one of the pair of clamp arms to move along the second direction, for example, so the clamp arm driving mechanism can drive one of the pair of clamp arms to move toward or away from the other clamp arm along the second direction, or drive the two clamp arms in the pair of clamp arms to move toward or away from each other along the second direction to adjust the clamping distance between the pair of clamp arms arranged opposite to each other.

[0148] In some embodiments, the clamp arm driving mechanism may include: an opening and closing guide rod and an opening and closing driving unit, wherein the opening and closing guide rod is arranged on the clamp seat along the second direction, and is used to set a pair of clamp arms, and the opening and closing driving unit is used to drive at least one of the pair of clamp arms to move along the opening and closing guide rod arranged in the second direction, for example, driving one of the pair of clamp arms to move toward or away from the other clamp arm along the opening and closing guide rod, or driving two of the pair of clamp arms to move toward or away from each other along the opening and closing guide rod. To ensure the stability of the clamp arm being able to move horizontally along the first direction, the number of the opening and closing guide rods may be multiple, for example, the opening and closing guide rods include two. Of course, the opening and closing guide rods may also be other numbers, for example, three, five, six, or more. Taking three as an example, the three opening and closing guide rods may be arranged in the form of an isosceles triangle or an equilateral triangle.

[0149] In some embodiments, the opening and closing driving unit includes a horizontal telescopic rod and a telescopic cylinder, one end of the horizontal telescopic rod is associated with a certain clamping arm, and the other end of the horizontal telescopic rod is associated with the telescopic cylinder, and the telescopic cylinder is arranged on the clamping seat. In practical applications, the telescopic cylinder can drive the horizontal telescopic rod to extend and retract. For example, the telescopic cylinder drives the horizontal telescopic rod to retract inward, drives a certain clamping arm to move along the opening and closing guide rod set in the second direction, reduces the clamping distance between the two clamping arms, and clamps the edge skin block located between the two clamping arms. Alternatively, the two telescopic cylinders associated with the two clamping arms respectively drive their respective horizontal telescopic rods to retract inward, respectively drive the associated clamping arms to move toward each other along the opening and closing guide rod set in the second direction, and reduce the clamping distance between the two clamping arms, so as to clamp the edge skin block located between the two clamping arms. Correspondingly, the telescopic cylinder can drive the horizontal telescopic rod to extend outward, drives a certain clamping arm to move along the opening and closing guide rod set in the second direction, and increases the clamping distance between the two clamping arms to release the clamped edge skin block. Alternatively, the two telescopic cylinders associated with the two clamping arms respectively drive their respective horizontal telescopic rods to extend outward, and respectively drive the associated clamping arms to move away from each other along the opening and closing guide rods set in the second direction, thereby increasing the clamping distance between the two clamping arms to release the clamped edge leather block.

[0150] In some embodiments, the opening and closing drive unit includes a screw and an opening and closing motor, one end of the screw (for example, a threaded end) is associated with a certain clamp arm, and the other end of the screw is associated with the opening and closing motor, and the opening and closing motor is arranged on the clamp seat. In practical applications, the opening and closing motor can drive the screw to rotate. For example, the opening and closing motor drives the screw to rotate forward (or drives the screw to rotate reversely), drives one of the pair of clamp arms to move toward the other clamp arm along the opening and closing guide rod set in the second direction, or drives the two clamp arms in the pair of clamp arms to move toward each other along the opening and closing guide rod set in the second direction, thereby reducing the clamping distance between the two clamp arms, so as to clamp the edge leather block located between the two clamp arms. Correspondingly, the opening and closing motor drives the screw to rotate reversely (or drives the screw to rotate forward), drives one of the pair of clamp arms to move away from the other clamp arm along the opening and closing guide rod set in the second direction, or drives the two clamp arms in the pair of clamp arms to move away from each other along the opening and closing guide rod set in the second direction, thereby increasing the clamping distance between the two clamp arms, so as to release the clamped edge leather block.

[0151] In some embodiments, the opening and closing drive unit includes a bidirectional screw and an opening and closing motor, wherein the bidirectional screw is arranged along the second direction, and the bidirectional screw is a left-handed screw, and two sections of threads are arranged on the rod body, and the rotation direction of the two sections of threads is opposite, that is, one section of the thread is a left-handed thread, and the other section of the thread is a right-handed thread, wherein one section of the thread can be associated with one clamping arm and the other section of the thread can be associated with another clamping arm (for example, the left-handed thread is associated with the first clamping arm and the right-handed thread is associated with the second clamping arm, or the right-handed thread is associated with the first clamping arm and the left-handed thread is associated with the second clamping arm), and the opening and closing motor is associated with the bidirectional screw, and is used to drive the bidirectional screw to rotate so that the associated first clamping arm and the second clamping arm move toward or away from each other along the opening and closing guide rod arranged in the second direction. In practical applications, for example, the opening and closing motor drives the bidirectional screw to rotate forward (or drives the bidirectional screw to rotate reversely), and then drives the two associated clamping arms to move toward each other along the opening and closing guide rod set in the second direction, thereby reducing the clamping distance between the two clamping arms, so as to clamp the edge leather block between the two clamping arms; or, the opening and closing motor drives the bidirectional screw to rotate reversely (or drives the bidirectional screw to rotate forward), and then drives the two associated clamping arms to move away from each other (i.e., away from each other) along the opening and closing guide rod set in the second direction, thereby increasing the clamping distance between the two clamping arms, so as to release the clamped edge leather block. The opening and closing motor can be arranged in the middle section or a terminal of the bidirectional screw.

[0152] In some embodiments, the clamping portion of the clamping arm is of a rotating design. The transport fixture includes a clamping portion rotating mechanism, which is used to drive the clamping portion on the clamping arm to rotate. In some implementations, the clamping portion of the clamping arm is driven by the clamping portion rotating mechanism to rotate around a clamping center line (for example, a center line connecting the clamping portions of the two clamping arms is used as the clamping center line), and the clamped edge leather block undergoes a corresponding rotation around the clamping center line. In actual processing operations, the edge leather block is driven to rotate along the clamping center line by the clamping portion rotating mechanism, and the positional relationship of the clamped edge leather block relative to the grinding device (for example, including a grinding device and a chamfering device) can be adjusted.

[0153] In some embodiments, the clamping part is a multi-point contact clamping head. It is understandable that the contact between the multi-point contact clamping head and the end face of the edge leather block is not limited to point contact. For example, the clamping part has a plurality of protrusions to contact the end face of the edge leather block, wherein each protrusion can be in surface contact with the end face of the edge leather block. In one implementation, the protrusion of the clamping part can also be connected to the clamping part body through a spring along a horizontal line, thereby forming a multi-point floating contact, so that the transport clamp can adapt to the flatness of the end face of the edge leather block when clamping the end face of the edge leather block to clamp the edge leather block.

[0154] In some embodiments, a pair of clamping portions of the transfer clamp are used to contact the edge leather block and are configured as a rigid structure to prevent the clamped edge leather block from being disturbed during the grinding operation (eg, including surface grinding and chamfering operations) and affecting the processing accuracy.

[0155] In practical applications, the clamping portion rotating mechanism may include a rotatable structure provided on two clamping portions of a pair of clamping arms and a driving source for driving at least one of the two rotatable structures to rotate.

[0156] In some embodiments of the present application, the clamping part of the clamping arm can be configured as a rotatable truncated cone, the circular plane of the truncated cone contacts the end face of the edge leather block, and remains relatively still with the end face of the edge leather block after being in close contact with the end face of the edge leather block. The clamping part also includes a locking structure, and the clamping part of the clamping arm is in a locked state when grinding a selected plane. When switching between different grinding surfaces, the clamping part rotates along the center of the truncated cone driven by the clamping part rotation mechanism.

[0157] In some implementations, the clamping portion of the clamping arm includes a rotatable truncated cone and a series of protruding contacts disposed on the truncated cone, wherein each contact has a contact plane for contacting the clamped edge leather block, and the truncated cone rotates driven by the rotating mechanism of the clamping portion. With regard to the contacts, in some implementations, the protruding length of the contacts, i.e., the position of the horizontal line, is adjustable, so that in the process of clamping the edge leather block, for the edge leather block with a lower end surface flatness, the protruding length of the contacts can be adjusted according to the end surface of the edge leather block, so that the contact surface of each contact is in a close contact state with the end surface of the edge leather block. The protruding length is the length of the horizontal line from the circular plane of the truncated cone to the contact plane of the contact.

[0158] The clamping part rotation mechanism may be arranged on one of the pair of clamping arms to drive the clamping part of the pair of clamping arms and the clamped edge leather piece to rotate; or the clamping part rotation mechanism may be arranged on both clamping arms of the pair of clamping arms to coordinate movement and control the two clamping parts of the pair of clamping arms to rotate at the same angle and direction. In some implementations, the driving source in the clamping part rotation mechanism may be, for example, a driving motor.

[0159] Thus, in the embodiment of the present application, the transfer clamp configured in the transfer device can be used to clamp the edge skin block horizontally and can drive the clamped edge skin block to rotate at a predetermined angle with the clamping center line as the rotation axis.

[0160] The transfer lifting mechanism is used to drive the transfer fixture to rise and fall vertically on the transfer mounting frame.

[0161] In some embodiments, the transfer lifting mechanism may include: a vertical lifting guide rail and a vertical lifting drive unit.

[0162] The vertical lifting guide rail may be arranged on the transfer mounting frame in the vertical direction (i.e., the third direction). For example, a mounting structure (e.g., a mounting plate) is provided on the transfer mounting frame, and the vertical lifting guide rail may be arranged on the mounting structure in the vertical direction (i.e., the third direction). Alternatively, the vertical lifting guide rail may be arranged on the transfer fixture in the vertical direction (i.e., the third direction). For example, a mounting structure (e.g., a mounting plate) is provided on the transfer fixture, and the vertical lifting guide rail may be arranged on the mounting structure in the vertical direction (i.e., the third direction). To ensure the stability of the transfer fixture in being able to move up and down along the vertical lifting guide rail, the number of the vertical lifting guide rails may be multiple, for example, the vertical lifting guide rails may include two.

[0163] In certain embodiments, the vertical lifting drive unit includes a vertical screw rod and a lifting motor, one end of the vertical screw rod is associated with the clamp seat of the transfer fixture or the mounting structure of the transfer fixture, the other end of the vertical screw rod is associated with the lifting motor, and the lifting motor is arranged on the transfer mounting frame or the mounting structure of the transfer mounting frame. In practical applications, the lifting motor can drive the vertical screw rod to rotate forward and reversely. For example, the lifting motor drives the vertical screw rod to rotate forward (or drives the vertical screw rod to rotate reversely), and drives the transfer fixture to rise along the vertical lifting guide rail set in the vertical direction. Correspondingly, the lifting motor can drive the vertical screw rod to rotate reversely (or drives the vertical screw rod to rotate forward), and drives the transfer fixture to descend along the vertical lifting guide rail set in the vertical direction.

[0164] In some embodiments, the transfer lifting mechanism may include: a vertical lifting guide rod and a vertical lifting drive unit.

[0165] The vertical lifting guide rod may be arranged on the transport mounting frame in the vertical direction (i.e., the third direction). For example, a mounting structure (e.g., a mounting plate) is arranged on the transport mounting frame, and the vertical lifting guide rod may be arranged on the mounting structure in the vertical direction (i.e., the third direction). To ensure the stability of the transport fixture in being able to move up and down along the vertical lifting guide rod, the number of the vertical lifting guide rods may be multiple, for example, the vertical lifting guide rods may include two.

[0166] In certain embodiments, the vertical lifting drive unit includes a vertical telescopic rod and a telescopic cylinder, one end of the vertical telescopic rod is associated with the clamp seat, and the other end of the vertical telescopic rod is associated with the telescopic cylinder, and the telescopic cylinder is arranged on the transport mounting frame or the mounting structure. In practical applications, the telescopic cylinder can drive the vertical telescopic rod to extend and retract. For example, the telescopic cylinder drives the vertical telescopic rod to retract inward, and drives the vertical lifting guide rod arranged along the vertical direction of the transport fixture to rise. Correspondingly, the telescopic cylinder can drive the vertical telescopic rod to extend outward, and drive the vertical lifting guide rod arranged along the vertical direction of the transport fixture to descend.

[0167] In certain embodiments, the vertical lifting drive unit includes a vertical screw rod and a lifting motor, one end of the vertical screw rod is associated with the clamp seat, and the other end of the vertical screw rod is associated with the lifting motor, and the lifting motor is arranged on the transfer mounting frame or the mounting structure. In practical applications, the lifting motor can drive the vertical screw rod to rotate forward and backward. For example, the lifting motor drives the vertical screw rod to rotate forward (or drives the vertical screw rod to rotate reversely), and drives the vertical lifting guide rod set along the vertical direction of the transfer fixture to rise. Correspondingly, the lifting motor can drive the vertical screw rod to rotate reversely (or drives the vertical screw rod to rotate forward), and drives the vertical lifting guide rod set along the vertical direction of the transfer fixture to descend.

[0168] The transfer translation mechanism is used to drive the transfer fixture to translate on the transfer mounting frame. The transfer translation mechanism is used to drive the transfer fixture to move on the transfer mounting frame along the second direction. The transfer translation mechanism includes: a transfer translation guide rail and a translation drive unit. The transfer translation guide rail can be arranged on the transfer mounting frame along the second direction, and the translation drive unit is used to drive the transfer fixture to move along the transfer translation guide rail arranged in the second direction.

[0169] In some embodiments, the translation drive unit includes a transfer translation rack, a driving gear and a driving source. The transfer translation rack is arranged on the transfer mounting frame along the second direction and is parallel to the transfer translation guide rail. The driving gear is arranged on the mounting structure and meshes with the transfer translation rack. The driving gear is driven to rotate by the driving source, and the gear teeth of the driving gear mesh with the transfer translation rack. Following the movement of the transfer translation rack, the mounting frame connected to the driving gear and the transfer fixture provided thereon move along the transfer translation guide rail. The driving source is, for example, a driving motor.

[0170] In some embodiments, the cutting travel drive unit includes a transport translation screw and a drive source, wherein the transport translation screw is arranged along the second direction and is associated with the mounting structure, and the drive source is used to drive the transport translation screw to rotate so that the associated mounting structure and the transport fixture provided therein move along the transport translation guide rail. The drive source is, for example, a drive motor.

[0171] By using the transfer device in the present application, the two end surfaces of the edge skin block can be clamped, and the edge skin block can be driven to rotate, lift, and translate.

[0172] As mentioned above, in some embodiments, each functional area can be arranged along the first direction or along the second direction. Taking the parallel arrangement along the first direction as an example, when the edge leather block grinding equipment includes a loading area, a grinding area, a chamfering area, and an unloading area, the loading area, the grinding area, the chamfering area, and the unloading area are arranged in parallel along the first direction (for example, in the form of a loading area, a grinding area, a chamfering area, and an unloading area, or in the form of a grinding area, a loading area, an unloading area, and a chamfering area, etc.). However, in each functional area, the placement of the edge leather blocks may still have different variations. For example, in some embodiments, the edge leather blocks in each functional area are all placed horizontally along the second direction, that is, the edge leather blocks are placed horizontally and the length direction of the horizontally placed edge leather blocks is consistent with the second direction. In some embodiments, although the edge skin blocks in each functional area are placed horizontally, the placement directions are not completely consistent. For example, the edge skin blocks in the grinding area are placed horizontally along the second direction, while the edge skin blocks in the chamfering area are placed horizontally along the first direction.

[0173] In embodiments involving different placement directions of edge skin blocks in various functional areas, the transfer device may further include a vertical rotation mechanism for driving the transfer clamp to rotate vertically, thereby driving the edge skin blocks clamped by the transfer clamp to change their placement direction.

[0174] In certain embodiments, the vertical rotation mechanism may include a rotating shaft and a rotating motor, wherein one end of the rotating shaft is associated with the transfer fixture (e.g., the clamping seat of the transfer fixture), and the other end of the rotating shaft is associated with the rotating motor. In practical applications, the rotating motor can drive the rotating shaft to rotate. For example, the rotating motor drives the rotating shaft to rotate forward (or drives the rotating shaft to rotate reversely), drives the transfer fixture to rotate forward (or reversely), so as to rotate the side leather block located between the two clamping arms forward (or reversely), and change the placement direction. Correspondingly, the rotating motor drives the rotating shaft to rotate reversely (or drives the rotating shaft to rotate forwardly), drives the transfer fixture to rotate reversely (or forward), so as to rotate the side leather block located between the two clamping arms reversely (or forward), and change the placement direction. Assuming that there are multiple placement directions of the edge skin block, for example, including a placement direction along the first direction and a placement direction along the second direction, the rotating motor in the vertical transfer mechanism drives the rotating shaft to rotate forward or reverse (for example, the steering angle can be 90°), which is used to drive the transfer fixture to rotate vertically to switch between the first direction and the second direction. However, this is not limited to this. For example, multiple placement directions of the edge skin blocks can be set, and the rotating motor in the vertical transfer mechanism drives the rotating shaft to rotate forward or reversely according to the angle difference between the initial placement direction and the target placement direction, which is used to drive the transfer fixture to rotate vertically to switch between the first direction and the second direction. Generally, in the vertical rotation mechanism of the transfer device, the rotating motor in the vertical transfer mechanism drives the rotating shaft to rotate only in one direction (for example, forward rotation or reverse rotation) and the rotation angle range can be limited to within 90° (including 90°).

[0175] In some embodiments, the transfer device includes a side skin block centering mechanism, which is arranged on the clamp seat and is used to make the center line of the side skin block placed horizontally consistent with the center line of the side skin block clamp in the width direction. The side skin block centering mechanism may include at least one pair of clamping members and a clamping member driving mechanism, wherein the at least one pair of clamping members are arranged opposite to each other along a first direction and are of movable design. At this time, the clamping member driving mechanism can drive the at least one pair of clamping members to move toward each other, so as to clamp the side skin block therebetween and ensure that the center line of the side skin block is located in the middle of the side skin block clamp, thereby realizing the centering of the side skin block.

[0176] The following is an explanation of the execution process of the edge leather block grinding device in the above embodiment:

[0177] First, the edge leather block to be ground is transported and placed in the grinding area by using the loading conveying device and the transfer device so that the end of the edge leather block along the length direction is clamped by the first edge leather block clamping device.

[0178] The surface grinding device is used to perform surface grinding on the four side surfaces of the edge leather block at the surface grinding area. Specifically, through the relative movement of the surface grinding device and the first edge leather block clamping device, at least one surface grinding tool in the surface grinding device performs surface grinding on at least one side surface exposed in the edge leather block clamped by the first edge leather block clamping device. After completing the surface grinding of at least one side surface, the edge leather block can be rotated by the first edge leather block clamping device to change the position of the edge leather block to expose other un-surfaced side surfaces, and at least one surface grinding tool in the surface grinding device continues to perform surface grinding on the new side surface until the surface grinding of the four side surfaces is completed.

[0179] The edge leather block that has completed the surface grinding operation is transferred by the transfer device and placed at the chamfering area so that the edge leather block is clamped by the third edge leather block clamping device at the end along the length direction, and the edge leather block to be ground is transferred by the loading conveying device and the transfer device and placed at the surface grinding area so that the edge leather block is clamped by the first edge leather block clamping device at the end along the length direction. Alternatively, the edge leather block that has completed the surface grinding operation is transferred by the transfer device and placed at the chamfering area so that the edge leather block is supported by the edge leather block supporting device, and the edge leather block to be ground is transferred by the loading conveying device and the transfer device and placed at the surface grinding area so that the edge leather block is clamped by the first edge leather block clamping device at the end along the length direction.

[0180] The chamfering device is used to chamfer the four edges of the edge leather block at the chamfering position, and the grinding device is used to grind the four side surfaces of the edge leather block at the grinding position. The chamfering device is used to chamfer the four edges of the edge leather block at the chamfering position, which may include: through the relative movement of the chamfering device and the third edge leather block clamping device, at least one chamfering grinder in the chamfering device performs a chamfering operation on at least one edge portion exposed in the edge leather block clamped by the third edge leather block clamping device, after completing the chamfering operation of at least one edge portion, the third edge leather block clamping device may be used to rotate the edge leather block to change the position of the edge leather block to expose other unchamfered edges, and at least one chamfering grinder in the chamfering device continues to chamfer the new edge portion until the chamfering operation of the four edges is completed. Alternatively, through the relative movement of the chamfering device and the edge leather block supporting device, a pair of chamfering units in the chamfering device chamfers the two exposed edges of the edge leather block supported by the edge leather block supporting device at the chamfering area. After the chamfering of the two edges is completed, the edge leather block can be rotated by the transfer device to change the position of the edge leather block to expose the other two unchamfered edges, and the pair of chamfering grinders in the chamfering device continue to chamfer the two newly exposed edges to complete the chamfering of the four edges. The surface grinding operation of the four side surfaces of the edge leather block at the surface grinding area by the surface grinding device is referred to the above description and will not be repeated here.

[0181] After the chamfering operation of the edge skin block is completed, the edge skin block after the chamfering operation is transferred to the unloading conveying device by using the transfer device and then unloaded.

[0182] In some embodiments, the processing platform is provided with a first type of grinding area, a second type of grinding area and a chamfering area arranged in parallel, the first type of grinding area is provided with a first type of grinding device, the second type of grinding area is provided with a second type of grinding device, and the chamfering area is provided with a chamfering device.

[0183] The first type of surface grinding device and the second type of surface grinding device are both used for surface grinding of edge leather blocks, wherein the edge leather blocks have four side surfaces to be ground, wherein the first type of surface grinding device is arranged at the first type of surface grinding area of ​​the processing platform, and is used for surface grinding of a pair of first side surfaces of the edge leather block located at the first type of surface grinding area, and the second type of surface grinding device is arranged at the second type of surface grinding area of ​​the processing platform, and is used for surface grinding of a pair of second side surfaces of the edge leather block located at the second type of surface grinding area.

[0184] In the present application, the edge leather block is placed horizontally at the first type of grinding surface position and the second type of grinding surface position of the processing platform. In order to ensure that the edge leather block can be stably placed at the first type of grinding surface position and the second type of grinding surface position, the edge leather block grinding device of the present application includes a first edge leather block clamping device and a second edge leather block clamping device.

[0185] The first edge leather block clamping device is arranged at the first type of grinding area, and is used to clamp the end of the edge leather block along the length direction. The first edge leather block clamping device is intended to clamp the edge leather block.

[0186] In some embodiments, the first type of surface grinding device includes a first surface grinding frame and a first surface grinding unit movably disposed on the first surface grinding frame. Correspondingly, the first edge leather block clamping device includes: a first bearing mounting seat and a first edge leather block clamp disposed on the first bearing mounting seat. The first edge leather block clamp may include a first clamping seat, at least one pair of first clamping members, and a first clamping member driving mechanism. The at least one pair of first clamping members is provided with a first clamping portion and a first clamping portion rotating mechanism.

[0187] In some embodiments, the first type of surface grinding device includes a first surface grinding frame and a pair of first surface grinding units movably arranged on the first surface grinding frame. Correspondingly, the first edge leather block clamping device includes: a first bearing mounting seat and a first edge leather block clamp arranged on the first bearing mounting seat, the first edge leather block clamp includes at least a pair of first clamping members, and a first clamping member driving mechanism for driving at least one first clamping member of the at least one pair of first clamping members to move.

[0188] The first bearing mounting seat is arranged on the machine base. In some embodiments, the first bearing mounting seat is arranged on the machine base along the second direction, and is used to set the first edge leather block clamp.

[0189] The first edge skin block clamp is used to clamp the edge skin block. The first edge skin block clamp may include a first clamping seat, at least one pair of first clamping members, and a first clamping member driving mechanism.

[0190] The at least one pair of first clamping members are arranged on opposite sides of the first clamping seat and arranged along the second direction. The at least one pair of first clamping members are controlled by the first clamping member driving mechanism to clamp the two end surfaces of the edge leather block so that the clamped edge leather block is placed horizontally along the second direction.

[0191] The first clamping member driving mechanism is used to drive at least one of the at least one pair of first clamping members to move along the second direction to adjust the clamping distance between the pair of first clamping members. In some embodiments, two first clamping members of the pair of first clamping members are arranged opposite to each other along the second direction, and the first clamping member driving mechanism can drive at least one of the pair of first clamping members to move along the second direction to adjust the clamping distance between the pair of first clamping members arranged opposite to each other.

[0192] In some embodiments, the first clamping member driving mechanism may include: an opening and closing guide rod and an opening and closing driving unit, wherein the opening and closing guide rod is arranged on the clamping seat along the second direction, and is used to set a pair of first clamping members, and the opening and closing driving unit is used to drive two first clamping members in the pair of first clamping members to move toward or away from each other along the opening and closing guide rod arranged in the second direction. In order to ensure the stability of the first clamping member being able to move horizontally along the second direction, the number of the opening and closing guide rods may be multiple, for example, there are two opening and closing guide rods. Of course, the opening and closing guide rods may also be other numbers, for example, three, five, six, or more. Taking three as an example, the three opening and closing guide rods may be arranged in the form of an isosceles triangle or an equilateral triangle.

[0193] In some embodiments, the opening and closing drive unit includes a horizontal telescopic rod and a telescopic cylinder, one end of the horizontal telescopic rod is associated with a first clamping member, and the other end of the horizontal telescopic rod is associated with the telescopic cylinder, and the telescopic cylinder is disposed on the first clamping seat. In practical applications, the telescopic cylinder can drive the horizontal telescopic rod to extend and retract. For example, the telescopic cylinder drives the horizontal telescopic rod to retract inward, drives one of the pair of first clamping members to move toward the other first clamping member along the opening and closing guide rod disposed in the second direction, or drives two of the pair of first clamping members to move toward each other along the opening and closing guide rod disposed in the second direction, thereby reducing the clamping distance between the two first clamping members, so as to clamp the edge leather block located between the two first clamping members. Correspondingly, the telescopic cylinder can drive the horizontal telescopic rod to extend outward, drive one of the pair of first clamping members to move back toward the other first clamping member along the opening and closing guide rod set in the second direction, or drive two of the pair of first clamping members to move back to each other along the opening and closing guide rod set in the second direction, thereby increasing the clamping distance between the two first clamping members to release the clamped edge leather block.

[0194] In some embodiments, the opening and closing drive unit includes a screw and an opening and closing motor, one end of the screw (for example, a threaded end) is associated with a first clamping member, and the other end of the screw is associated with the opening and closing motor, and the opening and closing motor is disposed on the first clamping seat. In practical applications, the opening and closing motor can drive the screw to rotate. For example, the opening and closing motor drives the screw to rotate in the forward direction (or drives the screw to rotate in the reverse direction), drives one of the pair of first clamping members to move toward the other first clamping member along the opening and closing guide rod disposed in the second direction, or drives two of the pair of first clamping members to move toward each other along the opening and closing guide rod disposed in the second direction, thereby reducing the clamping distance between the two first clamping members, so as to clamp the edge leather block located between the two first clamping members. Correspondingly, the opening and closing motor drives the screw rod to rotate in the opposite direction (or drives the screw rod to rotate in the forward direction), drives one of the pair of first clamping members to move along the opening and closing guide rod set in the second direction away from the other first clamping member, or drives two of the pair of first clamping members to move along the opening and closing guide rod set in the second direction away from each other, thereby increasing the clamping distance between the two first clamping members to release the clamped edge leather block.

[0195] In some embodiments, the opening and closing drive unit includes a bidirectional screw and an opening and closing motor, wherein the bidirectional screw is arranged along the second direction, and the bidirectional screw is a left-handed screw, and two sections of threads are arranged on the rod body, and the rotation directions of the two sections of threads are opposite, that is, one section of thread is a left-handed thread, and the other section of thread is a right-handed thread, wherein one section of thread can be associated with a first clamping member and the other section of thread can be associated with another first clamping member (for example, the left-handed thread is associated with the first first clamping member and the right-handed thread is associated with the second first clamping member, or the right-handed thread is associated with the first first clamping member and the left-handed thread is associated with the second first clamping member), and the opening and closing motor is associated with the bidirectional screw, and is used to drive the bidirectional screw to rotate so that the two associated first clamping members move toward or away from each other along the opening and closing guide rod arranged in the second direction. In practical applications, for example, the opening and closing motor is used to drive the bidirectional screw to rotate forward (or to drive the bidirectional screw to rotate reversely), and then the two first clamping members associated therewith are driven to move toward each other (i.e., approach each other) along the opening and closing guide rod set in the second direction, and the clamping distance between the two first clamping members is reduced to clamp the edge leather block located between the two first clamping members; or, the opening and closing motor is used to drive the bidirectional screw to rotate reversely (or to drive the bidirectional screw to rotate forward), and then the two first clamping members associated therewith are driven to move away from each other (i.e., move away from each other) along the opening and closing guide rod set in the second direction, and the clamping distance between the two first clamping members is increased to release the clamped edge leather block. The opening and closing motor can be arranged in the middle section or a terminal of the bidirectional screw.

[0196] Thus, in the present application, after the end of the edge leather block along the length direction is clamped by the first edge leather block clamping device, a first side surface or a pair of first side surfaces to be polished can be exposed.

[0197] In some embodiments, in the first edge leather block clamping device, the first bearing mount is arranged at the bottom, the clamping seat of the first edge leather block clamp is arranged above the first bearing mount, and the at least one pair of first clamping members are arranged on the first clamping seat and are arranged upward. In some embodiments, after the at least one pair of first clamping members clamp the edge leather block, the first side surface located at the top can be fully exposed, and the first side surface located at the top is used as the side surface to be ground. Therefore, the first type of grinding device at the first type of grinding area can include at least one first grinding tool (for example, one first grinding tool or two parallel first grinding tools), and the grinding surface of the at least one grinding tool is horizontally facing downward. In some embodiments, after clamping the edge leather block, the at least one pair of first clamping members can fully expose the other three side surfaces except the bottom side surface adjacent to the clamping seat, that is, the top side surface and its adjacent left and right two first side surfaces. Therefore, the exposed left and right two first side surfaces are used as the side surfaces to be ground. Therefore, the grinding device at the grinding area may include at least one pair of grinding tools, and the at least one pair of grinding tools are arranged opposite to each other on the left and right.

[0198] In some embodiments, in the first edge leather block clamping device, the first bearing mount is arranged at the bottom and extends upward or is arranged at the side, the first clamping seat of the first edge leather block clamp is arranged at one side of the first bearing mount, and the at least one pair of first clamping members are arranged at the first clamping seat and are arranged to the left or right. In some embodiments, after the at least one pair of first clamping members clamp the edge leather block, the first side surface located at the far left (or far right) can be fully exposed, and the first side surface located at the far left (or far right) is used as the side surface to be ground. Therefore, the first type of grinding device at the first type of grinding area may include at least one first grinding tool (for example, one first grinding tool or two parallel first grinding tools), and the grinding surface of the at least one first grinding tool is horizontally facing right (or horizontally facing left). In some embodiments, after clamping the edge leather block, the at least one pair of first clamping members can fully expose the other three side surfaces except the side surface located on the far right (or far left) adjacent to the clamping seat, that is, the side surface located on the far left and its adjacent upper and lower first side surfaces. Therefore, the exposed upper and lower first side surfaces serve as the side surfaces to be ground. Therefore, the grinding device at the grinding area may include at least one pair of grinding tools, and the at least one pair of grinding tools are arranged opposite to each other up and down.

[0199] In the foregoing description, with respect to the first side surface that is not exposed in the edge skin block, in certain embodiments, other auxiliary fixtures (such as a transfer device, etc.) can be used to rotate or turn over the edge skin block placed on the first edge skin block clamping device to change the position of the edge skin block so as to expose the first side surface that was not exposed originally.

[0200] In addition, in the present application, the first edge skin block clamping device may still have other changes. For example, in some embodiments, the first edge skin block clamping device includes: a first clamping portion provided on the first clamping member and a first clamping portion rotating mechanism for driving the first clamping portion of the first clamping member to rotate. The first clamping portion can be driven to rotate by the first clamping portion rotating mechanism, which can drive the edge skin block clamped between the first clamping members to rotate to adjust the position of each side surface.

[0201] In some embodiments, in the first edge leather block clamping device, the first bearing mounting seat is arranged at the bottom, the first clamping seat of the first edge leather block clamp is arranged above the first bearing mounting seat, and the at least one pair of first clamping members are arranged on the first clamping seat and are arranged upward. In some embodiments, after the at least one pair of first clamping members clamp the edge leather block, the first side surface located at the top can be fully exposed, and the first side surface located at the top is used as the side surface to be ground. Therefore, the first type of grinding device at the first type of grinding area may include at least one first grinding tool (for example, a first grinding tool or two parallel first grinding tools), and the grinding surface of the at least one first grinding tool is horizontally facing downward. After the top first side surface is ground by the first grinding tool and the grinding operation is completed, the first clamping part is driven to rotate (for example, 180°) by the first clamping part rotation mechanism to drive the first clamping part to rotate (for example, 180°) to drive the edge leather block to rotate (for example, 180°) to expose the other first side surface opposite to it, and the exposed other first side surface can still be ground by the first grinding tool. In this way, when the first grinding tool does not change its position, the edge leather block is driven to rotate by the first clamping part rotating mechanism to complete the grinding operation of a pair of first side surfaces in the edge leather block.

[0202] In some embodiments, in the first edge leather block clamping device, the first bearing mount is arranged at the bottom and extends upward or is arranged at the side, the first clamping seat of the first edge leather block clamp is arranged at one side of the first bearing mount, and the at least one pair of first clamping members are arranged at the first clamping seat and are arranged to the left or right. In some embodiments, after the at least one pair of first clamping members clamp the edge leather block, the first side surface located at the far left (or far right) can be fully exposed, and the first side surface located at the far left (or far right) is used as the side surface to be ground. Therefore, the first type of grinding device at the first type of grinding area may include at least one first grinding tool (for example, one first grinding tool or two parallel first grinding tools), and the grinding surface of the at least one first grinding tool is horizontally facing right (or horizontally facing left). When the first side surface on the far left (or far right) is ground by the first grinding tool and the grinding operation is completed, the first clamping part rotation mechanism is used to drive the first clamping part to rotate (for example, 180 degrees) to drive the edge leather block to rotate (for example, 180 degrees) to expose the other first side surface opposite to the first side surface, and the exposed other first side surface can still be ground by the first grinding tool. In this way, when the first grinding tool does not change its position, the first clamping part rotation mechanism drives the edge leather block to rotate, and the grinding operation of a pair of first side surfaces in the edge leather block is completed.

[0203] In some embodiments, the first clamping portion is a multi-point contact clamping head. It is understandable that the contact method between the multi-point contact clamping head and the end face of the edge skin block is not limited to point contact. For example, the first clamping portion has a plurality of protrusions to contact the end face of the edge skin block, wherein each protrusion can be in surface contact with the end face of the edge skin block.

[0204] In some embodiments, a pair of first clamping parts in the pair of first clamping members are configured as rigid structures for contacting the edge leather block to prevent the clamped edge leather block from being disturbed during the surface grinding operation and affecting the processing accuracy.

In some examples, the driving source may be, for example, a driving motor.

[0215] The first grinding tool includes at least one grinding wheel. For example, in some embodiments, the first type of grinding device includes a first grinding tool, the first grinding tool includes a grinding wheel, and the grinding wheel is a rough grinding wheel or a fine grinding wheel. In some embodiments, the first type of grinding device may include two first grinding tools arranged along the second direction, each of which includes a grinding wheel, for example, the first grinding tool in front includes a rough grinding wheel, and the first grinding tool in the back includes a fine grinding wheel. The first type of grinding device includes a first grinding tool, the first grinding tool includes a rough grinding wheel and a fine grinding wheel nested in each other, for example, the rough grinding wheel is nested in the fine grinding wheel, or, the fine grinding wheel is nested in the rough grinding wheel. Wherein, the abrasive grain size of the fine grinding wheel is smaller than the abrasive grain size of the rough grinding wheel, and the abrasive grain density of the fine grinding wheel is greater than the abrasive grain density of the rough grinding wheel.

[0216] When the first surface grinding tool includes a rough grinding wheel and a fine grinding wheel, the first surface grinding tool can be used to perform rough grinding and fine grinding on the first side of the edge leather block. Therefore, at least one of the rough grinding wheel and the fine grinding wheel is provided with a telescopic driving mechanism. For example, when the rough grinding wheel is nested in the fine grinding wheel, the rough grinding wheel can be provided with a telescopic driving mechanism, and when performing the rough grinding operation, the telescopic driving mechanism is used to drive the rough grinding wheel to extend and protrude from the fine grinding wheel, so that the protruding rough grinding wheel can be used to perform the rough grinding operation on the first side of the edge leather block, and when performing the fine grinding operation, the telescopic driving mechanism is used to drive the rough grinding wheel to retract and be recessed in the fine grinding wheel, so that the fine grinding wheel can be used to perform the fine grinding operation on the first side of the edge leather block.

When performing the rough grinding operation, the telescopic driving mechanism is utilized to drive the rough grinding wheel to extend and protrude from the fine grinding wheel, so that the protruding rough grinding wheel can be used to perform the rough grinding operation on the first side surface of the edge leather block. When performing the fine grinding operation, the telescopic driving mechanism is utilized to drive the rough grinding wheel to retract and be recessed into the fine grinding wheel, so that the fine grinding wheel can be used to perform the fine grinding operation on the first side surface of the edge leather block.

[0219] Taking the mobile first type surface grinding device as an example, the first type surface grinding device includes a first surface grinding frame travel mechanism, and the first surface grinding frame and the first surface grinding unit provided thereon are driven to move along the second direction by the first surface grinding frame travel mechanism.

[0221] In some embodiments, the first grinding surface advancing driving unit includes a first grinding surface advancing rack, a driving gear, and a driving source. The first grinding surface advancing rack is arranged on the machine base along the second direction, parallel to the first grinding surface advancing guide rail. The driving gear is arranged on the first grinding surface frame (for example, the bottom of the first grinding surface frame), and meshes with the first grinding surface advancing rack. The driving gear is driven to rotate by the driving source, and the gear teeth of the driving gear mesh with the first grinding surface advancing rack. Following the movement of the first grinding surface advancing rack, the first grinding surface frame connected to the driving gear and the first grinding surface unit provided thereon move along the first grinding surface advancing guide rail.

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

[0223] When the first grinding device is used to grind the first side surface of the edge leather block at the first type of grinding area, the first grinding frame travel mechanism drives the first grinding frame and the first grinding unit provided therein to move in the second direction so as to achieve relative movement with the edge leather block clamped by the first edge leather block clamping device at the first grinding area so that the first grinding tool in the first grinding unit can grind the first side surface of the edge leather block clamped by the first edge leather block clamping device at the first type of grinding area.

[0224] Taking the movable edge skin block clamping device as an example, the first edge skin block clamping device includes a first clamping and traveling mechanism, and the first clamping and traveling mechanism is used to drive the first edge skin block clamping device and the edge skin block clamped by it to move along the second direction.

[0225] In some embodiments, the first clamping and traveling mechanism includes: a first clamping and traveling guide rail and a first clamping and traveling drive unit, wherein the first clamping and traveling guide rail is arranged on the first bearing mounting seat along the second direction, and the first clamping and traveling drive unit is used to drive the first edge skin block clamp and the edge skin block clamped therein to move along the first clamping and traveling guide rail.

[0226] In some embodiments, the first clamping and traveling driving unit includes a first clamping and traveling rack, a driving gear, and a driving source. The first clamping and traveling rack is arranged on the first bearing mounting seat along the second direction, parallel to the first clamping and traveling guide rail. The driving gear is arranged on the first side leather block clamp and meshes with the first clamping and traveling guide rail. The driving gear is driven to rotate by the driving source, and the gear teeth of the driving gear mesh with the first clamping and traveling guide rail. Following the movement of the first clamping and traveling guide rail, the first side leather block clamp connected to the driving gear and the side leather block clamped therein move along the first clamping and traveling guide rail. The driving source is, for example, a driving motor.

[0227] In some embodiments, the first clamping and traveling driving unit includes a first clamping and traveling screw and a driving source, wherein the first clamping and traveling screw is arranged along the second direction and is associated with the first side skin block clamp, and the driving source is used to drive the first clamping and traveling screw to rotate so that the associated first side skin block clamp and the side skin block clamped therein move along the first clamping and traveling guide rail. The driving source is, for example, a driving motor.

[0228] When the first type of grinding device is used to grind the first side surface of the edge leather block in the first type of grinding area, the first edge leather block clamp and the edge leather block clamped by it are driven by the first clamping and moving mechanism to move in the second direction to achieve relative movement with the first grinding unit in the first type of grinding device so that the first grinding tool in the first grinding unit can grind the first side surface of the first edge leather block clamp and the edge leather block clamped by it.

[0229] The second edge leather block clamping device is arranged at the second type of grinding area and is used to clamp the end of the edge leather block along the length direction. The second edge leather block clamping device is intended to clamp the edge leather block.

[0230] In some embodiments, the second type of surface grinding device includes a second surface grinding frame and a second surface grinding unit movably arranged on the second surface grinding frame. Correspondingly, the second side leather block clamping device includes: a second bearing mounting seat and a second side leather block clamp arranged on the second bearing mounting seat. The second side leather block clamp may include a second clamping seat, at least one pair of second clamping members, and a second clamping member driving mechanism. The at least one pair of second clamping members is provided with a second clamping part and a second clamping part rotation mechanism.

[0231] In some embodiments, the second type of surface grinding device includes a second surface grinding frame and a pair of second surface grinding units movably arranged on the second surface grinding frame. Correspondingly, the second edge leather block clamping device includes: a second bearing mounting seat and a second edge leather block clamp arranged on the second bearing mounting seat, the second edge leather block clamp includes at least a pair of second clamping members, and a second clamping member driving mechanism for driving at least one second clamping member of the at least one pair of second clamping members to move.

[0232] The second bearing mounting seat is arranged on the machine base. In some embodiments, the second bearing mounting seat is arranged on the machine base along the second direction, and is used to set the second edge leather block clamp.

[0233] The second edge skin block clamp is used to clamp the edge skin block. The second edge skin block clamp may include a second clamping seat, at least one pair of second clamping members, and a second clamping member driving mechanism.

[0234] The at least one pair of second clamping members are arranged on opposite sides of the second clamping seat and along the second direction. The at least one pair of second clamping members are controlled by the second clamping member driving mechanism to clamp the two end surfaces of the edge leather block so that the clamped edge leather block is placed horizontally along the second direction.

[0235] The second clamping member driving mechanism is used to drive at least one of the at least one pair of second clamping members to move along the second direction to adjust the clamping distance between the pair of second clamping members. In some embodiments, two second clamping members of the pair of second clamping members are arranged opposite to each other along the second direction, and the second clamping member driving mechanism can drive at least one of the pair of second clamping members to move along the second direction to adjust the clamping distance between the pair of second clamping members arranged opposite to each other.

[0236] In some embodiments, the second clamping member driving mechanism may include: an opening and closing guide rod and an opening and closing driving unit, wherein the opening and closing guide rod is arranged on the clamping seat along the second direction, and is used to set a pair of second clamping members, and the opening and closing driving unit is used to drive two second clamping members in the pair of second clamping members to move toward or away from each other along the opening and closing guide rod arranged in the second direction. In order to ensure the stability of the second clamping member being able to move horizontally along the second direction, the number of the opening and closing guide rods may be multiple, for example, there are two opening and closing guide rods. Of course, the opening and closing guide rods may also be other numbers, for example, three, five, six, or more. Taking three as an example, the three opening and closing guide rods may be arranged in the form of an isosceles triangle or an equilateral triangle.

[0237] In some embodiments, the opening and closing drive unit includes a horizontal telescopic rod and a telescopic cylinder, one end of the horizontal telescopic rod is associated with a second clamping member, and the other end of the horizontal telescopic rod is associated with the telescopic cylinder, and the telescopic cylinder is disposed on the second clamping seat. In practical applications, the telescopic cylinder can drive the horizontal telescopic rod to extend and retract. For example, the telescopic cylinder drives the horizontal telescopic rod to retract inward, drives one of the pair of second clamping members to move toward the other second clamping member along the opening and closing guide rod disposed in the second direction, or drives two of the pair of second clamping members to move toward each other along the opening and closing guide rod disposed in the second direction, thereby reducing the clamping distance between the two second clamping members, so as to clamp the edge leather block located between the two second clamping members. Correspondingly, the telescopic cylinder can drive the horizontal telescopic rod to extend outward, drive one of the pair of second clamping members to move back toward the other second clamping member along the opening and closing guide rod set in the second direction, or drive two of the pair of second clamping members to move back to each other along the opening and closing guide rod set in the second direction, thereby increasing the clamping distance between the two second clamping members to release the clamped edge leather block.

[0238] In some embodiments, the opening and closing drive unit includes a screw and an opening and closing motor, one end of the screw (for example, a threaded end) is associated with a second clamping member, and the other end of the screw is associated with the opening and closing motor, and the opening and closing motor is disposed on the second clamping seat. In practical applications, the opening and closing motor can drive the screw to rotate. For example, the opening and closing motor drives the screw to rotate forward (or drives the screw to rotate reversely), drives one of the pair of second clamping members to move toward the other second clamping member along the opening and closing guide rod disposed in the second direction, or drives two of the pair of second clamping members to move toward each other along the opening and closing guide rod disposed in the second direction, thereby reducing the clamping distance between the two second clamping members, so as to clamp the edge leather block located between the two second clamping members. Correspondingly, the opening and closing motor drives the screw rod to rotate in the opposite direction (or drives the screw rod to rotate in the forward direction), drives one of the pair of second clamping members to move along the opening and closing guide rod set in the second direction toward the other second clamping member, or drives two of the pair of second clamping members to move along the opening and closing guide rod set in the second direction toward each other, thereby increasing the clamping distance between the two second clamping members to release the clamped edge leather block.

[0239] In some embodiments, the opening and closing drive unit includes a bidirectional screw and an opening and closing motor, wherein the bidirectional screw is arranged along the second direction, and the bidirectional screw is a left-handed screw, and two sections of threads are arranged on the rod body, and the rotation direction of the two sections of threads is opposite, that is, one section of thread is a left-handed thread, and the other section of thread is a right-handed thread, wherein one section of thread can be associated with a second clamping member and the other section of thread can be associated with another second clamping member (for example, the left-handed thread is associated with the first second clamping member and the right-handed thread is associated with the second second clamping member, or the right-handed thread is associated with the first second clamping member and the left-handed thread is associated with the second second clamping member), and the opening and closing motor is associated with the bidirectional screw, and is used to drive the bidirectional screw to rotate so that the two associated second clamping members move toward or away from each other along the opening and closing guide rod arranged in the second direction. In practical applications, for example, the opening and closing motor drives the bidirectional screw to rotate forward (or drives the bidirectional screw to rotate reversely), and then drives the two associated second clamping members to move toward each other (i.e., approach each other) along the opening and closing guide rod set in the second direction, and reduces the clamping distance between the two second clamping members, so as to clamp the edge leather block located between the two second clamping members; or, the opening and closing motor drives the bidirectional screw to rotate reversely (or drives the bidirectional screw to rotate forward), and then drives the two associated second clamping members to move away from each other (i.e., move away from each other) along the opening and closing guide rod set in the second direction, and increases the clamping distance between the two second clamping members, so as to release the clamped edge leather block. The opening and closing motor can be arranged in the middle section or a terminal of the bidirectional screw.

[0240] Thus, in the present application, after the end of the edge leather block along the length direction is clamped by the second edge leather block clamping device, a second side surface or a pair of second side surfaces to be polished can be exposed.

[0241] In some embodiments, in the second edge leather block clamping device, the second bearing mount is arranged at the bottom, the clamping seat of the second edge leather block clamp is arranged above the second bearing mount, and the at least one pair of second clamping members are arranged on the second clamping seat and are arranged upward. In some embodiments, after the at least one pair of second clamping members clamp the edge leather block, the second side surface located at the top can be fully exposed, and the second side surface located at the top is used as the side surface to be ground. Therefore, the second type of grinding device at the second type of grinding area can include at least one second grinding tool (for example, one second grinding tool or two parallel second grinding tools), and the grinding surface of the at least one grinding tool is horizontally facing downward. In some embodiments, after clamping the edge leather block, the at least one pair of second clamping members can fully expose the other three side surfaces except the bottom side surface adjacent to the clamping seat, that is, the top side surface and its adjacent left and right second side surfaces. Therefore, the exposed left and right second side surfaces serve as the side surfaces to be ground. Therefore, the grinding device at the grinding area may include at least one pair of grinding tools, and the at least one pair of grinding tools are arranged opposite to each other on the left and right.

[0242] In some embodiments, in the second edge leather block clamping device, the second bearing mount is arranged at the bottom and extends upward or is arranged at the side, the second clamping seat of the second edge leather block clamp is arranged at one side of the second bearing mount, and the at least one pair of second clamping members are arranged at the second clamping seat and are arranged to the left or right. In some embodiments, after the at least one pair of second clamping members clamp the edge leather block, the second side surface located at the far left (or far right) can be fully exposed, and the second side surface located at the far left (or far right) is used as the side surface to be ground. Therefore, the second type of grinding device at the second type of grinding area may include at least one second grinding tool (for example, a second grinding tool or two parallel second grinding tools), and the grinding surface of the at least one second grinding tool is horizontally facing right (or horizontally facing left). In some embodiments, after clamping the edge leather block, the at least one pair of second clamping members can fully expose the other three side surfaces except the side surface located on the far right (or far left) adjacent to the clamping seat, that is, the side surface located on the far left and its adjacent upper and lower second side surfaces. Therefore, the exposed upper and lower second side surfaces serve as the side surfaces to be ground. Therefore, the grinding device at the grinding area may include at least one pair of grinding tools, and the at least one pair of grinding tools are arranged opposite to each other up and down.

[0243] In the foregoing description, with respect to the second side surface of the edge skin block that is not exposed, in certain embodiments, other auxiliary fixtures (such as a transfer device, etc.) can be used to rotate or turn over the edge skin block placed on the second edge skin block clamping device to change the position of the edge skin block so as to expose the second side surface that was not exposed originally.

[0244] In addition, in the present application, the second side skin block clamping device may still have other changes. For example, in some embodiments, the second side skin block clamping device includes: a second clamping portion provided on the second clamping piece and a second clamping portion rotating mechanism for driving the second clamping portion of the second clamping piece to rotate. The second clamping portion rotating mechanism is used to drive the second clamping portion to rotate, which can drive the side skin block clamped between the second clamping pieces to rotate to adjust the position of each side surface.

[0245] In some embodiments, in the second edge leather block clamping device, the second bearing mounting seat is arranged at the bottom, the second clamping seat of the second edge leather block clamp is arranged above the second bearing mounting seat, and the at least one pair of second clamping members are arranged on the second clamping seat and are arranged upward. In some embodiments, after the at least one pair of second clamping members clamp the edge leather block, the second side surface located at the top can be fully exposed, and the second side surface located at the top is used as the side surface to be ground. Therefore, the second type of grinding device at the second type of grinding area may include at least one second grinding tool (for example, a second grinding tool or two parallel second grinding tools), and the grinding surface of the at least one second grinding tool is horizontally facing downward. After the second grinding tool grinds the top second side surface and completes the grinding operation, the second clamping part rotation mechanism drives the second clamping part to rotate (for example, 180°) to drive the edge leather block to rotate (for example, 180°) to expose the other second side surface opposite to it, and the exposed other second side surface can still be ground by the second grinding tool. In this way, when the second grinding tool does not change its position, the edge leather block is driven to rotate by the second clamping part rotating mechanism to complete the grinding operation of a pair of second side surfaces in the edge leather block.

[0246] In some embodiments, in the second edge leather block clamping device, the second bearing mount is arranged at the bottom and extends upward or is arranged at the side, the second clamping seat of the second edge leather block clamp is arranged at one side of the second bearing mount, and the at least one pair of second clamping members are arranged at the second clamping seat and are arranged to the left or right. In some embodiments, after the at least one pair of second clamping members clamp the edge leather block, the second side surface located at the far left (or far right) can be fully exposed, and the second side surface located at the far left (or far right) is used as the side surface to be ground. Therefore, the second type of grinding device at the second type of grinding area may include at least one second grinding tool (for example, a second grinding tool or two parallel second grinding tools), and the grinding surface of the at least one second grinding tool is horizontally facing right (or horizontally facing left). When the second side surface on the far left (or far right) is ground by the second grinding tool and the grinding is completed, the second clamping part rotation mechanism is used to drive the second clamping part to rotate (for example, 180 degrees) to drive the edge leather block to rotate (for example, 180 degrees) to expose the other second side surface opposite to the edge leather block, and the exposed second side surface can still be ground by the second grinding tool. In this way, when the second grinding tool does not change its position, the second clamping part rotation mechanism drives the edge leather block to rotate, and the grinding of a pair of second side surfaces in the edge leather block is completed.

[0247] In some embodiments, the second clamping portion is a multi-point contact clamping head. It is understandable that the contact method between the multi-point contact clamping head and the end face of the edge skin block is not limited to point contact. For example, the second clamping portion has a plurality of protrusions to contact the end face of the edge skin block, and each protrusion can be in surface contact with the end face of the edge skin block.

[0248] In some embodiments, a portion of a pair of second clamping parts in the pair of second clamping members for contacting the edge leather block is configured as a rigid structure to prevent the clamped edge leather block from being disturbed during the surface grinding operation and affecting the processing accuracy.

[0249] In practical applications, the second clamping portion rotating mechanism may include a rotatable structure provided on two second clamping portions of a pair of second clamping members and a driving source for driving at least one of the two rotatable structures to rotate.

[0250] In some embodiments of the present application, the second clamping part of the second clamping member can be configured as a rotatable truncated table, the circular plane of the truncated table contacts the end face of the edge leather block, and remains relatively still with the end face of the edge leather block after being in close contact with the end face of the edge leather block. The second clamping part also includes a locking structure, and the second clamping part is in a locked state when grinding a selected plane. When switching between different grinding surfaces, the second clamping part rotates along the center of the truncated table driven by the second clamping part rotation mechanism.

[0273] The chamfering device is arranged at the chamfering area of ​​the processing platform, and is used to chamfer the edges of the edge leather block located at the chamfering area. The edge leather block has four edges, so the chamfering device is used to chamfer the four edges of the edge leather block.

[0274] In the present application, the edge skin block is placed horizontally at the chamfering area of ​​the processing platform.

[0278] In the following description, an example is taken in which the edge skin block is horizontally placed at the chamfered area and the length direction of the edge skin block is consistent with the second direction.

[0279] The third bearing mounting seat is arranged on the machine base. In some embodiments, the third bearing mounting seat is arranged on the machine base along the second direction, and is used to set the third edge leather block clamp.

The at least one pair of third clamping members are controlled by the third clamping member driving mechanism to clamp the two end surfaces of the edge leather block so that the clamped edge leather block is placed horizontally along the second direction.

[0282] The third clamping member driving mechanism is used to drive at least one of the at least one pair of third clamping members to move along the second direction to adjust the clamping distance between the pair of third clamping members. In some embodiments, two third clamping members of the pair of third clamping members are arranged opposite to each other along the second direction, and the third clamping member driving mechanism can drive at least one of the pair of third clamping members to move along the second direction to adjust the clamping distance between the pair of third clamping members arranged opposite to each other.

[0283] In some embodiments, the third clamping member driving mechanism may include: an opening and closing guide rod and an opening and closing driving unit, wherein the opening and closing guide rod is arranged on the clamping seat along the second direction, and is used to set a pair of third clamping members, and the opening and closing driving unit is used to drive two third clamping members in the pair of third clamping members to move toward or away from each other along the opening and closing guide rod arranged in the second direction. In order to ensure the stability of the third clamping member being able to move horizontally along the second direction, the number of the opening and closing guide rods may be multiple, for example, there are two opening and closing guide rods. Of course, the opening and closing guide rods may also be other numbers, for example, three, five, six, or more. Taking three as an example, the three opening and closing guide rods may be arranged in the form of an isosceles triangle or an equilateral triangle.

[0284] In some embodiments, the opening and closing drive unit includes a horizontal telescopic rod and a telescopic cylinder, one end of the horizontal telescopic rod is associated with a third clamping member, and the other end of the horizontal telescopic rod is associated with the telescopic cylinder, and the telescopic cylinder is disposed on the third clamping seat.

[0287] Thus, in the present application, after the end of the edge leather block along the length direction is clamped by the third edge leather block clamping device, at least one edge portion to be chamfered can be exposed.

[0288] In some embodiments, in the third edge leather block clamping device, the third bearing mount is arranged at the bottom, the clamping seat of the third edge leather block clamp is arranged above the third bearing mount, and the at least one pair of third clamping members are arranged on the third clamping seat and are arranged upward. In some embodiments, after the at least one pair of third clamping members clamp the edge leather block, the uppermost edge portion can be fully exposed, and the uppermost edge portion is used as the edge portion to be chamfered. Therefore, the chamfering device at the chamfering position may include at least one chamfering grinder (for example, a chamfering grinder or two parallel chamfering grinders), and the chamfering surface of the at least one chamfering grinder is horizontally facing downward. In some embodiments, after the at least one pair of third clamping members clamp the edge leather block, the two left and right edges arranged above can be fully exposed (at this time, the side surface of the edge leather block is arranged horizontally or vertically), that is, the two exposed edges are used as the edges to be chamfered. Therefore, the chamfering device at the chamfering position may include a pair of chamfering grinders arranged at an angle. For example, in one example, one of the pair of chamfering grinders is at an angle of 45° to the horizontal or vertical, and the other of the pair of chamfering grinders is at an angle of 45° to the horizontal or vertical. Of course, the above-mentioned angles are not limited to this, and in different embodiments, other angles can be selected, for example, the inclination angle can be any angle between 40° and 60°, and is not limited to integer degrees.

[0289] In some embodiments, in the third edge leather block clamping device, the third bearing mount is arranged at the bottom and extends upward or is arranged at the side, the third clamping seat of the third edge leather block clamp is arranged at one side of the third bearing mount, and the at least one pair of third clamping members are arranged at the third clamping seat and are arranged to the left or right. In some embodiments, after the at least one pair of third clamping members clamp the edge leather block, the edge located on the far left (or far right) can be fully exposed, and the edge on the far left (or far right) is used as the edge to be chamfered. Therefore, the chamfering device at the chamfering position may include at least one chamfering grinder (for example, one chamfering grinder or two parallel chamfering grinders), and the chamfering surface of the at least one chamfering grinder is horizontally facing right (or horizontally facing left). In certain embodiments, after the at least one pair of third clamping members clamp the edge leather block, the two upper and lower edges located on the left side (or right side) can be fully exposed (in this case, the side surface of the edge leather block is arranged horizontally or vertically), that is, the two exposed edges are used as the edges to be chamfered, so the chamfering device at the chamfering position may include a pair of chamfering grinders arranged at an angle. For example, in a certain example, one of the pair of chamfering grinders is at a 45° angle to the horizontal line or the vertical, and the other chamfering grinder in the pair of chamfering grinders is at a 45° angle to the horizontal line or the vertical. Of course, the above-mentioned angle is not limited to this, and in different embodiments, other angles can be selected, for example, the inclination angle can be any angle from 40° to 60°, and is not limited to integer degrees.

[0290] In the foregoing description, with respect to the unexposed edges of the edge skin block, in certain embodiments, other auxiliary fixtures (such as a transfer device, etc.) can be used to rotate or turn over the edge skin block placed on the third edge skin block clamping device to change the position of the edge skin block so as to expose the previously unexposed edges.

[0291] In addition, in the present application, the third edge leather block clamping device may still have other changes. For example, in some embodiments, the third edge leather block clamping device includes: a third clamping portion provided on the third clamping piece and a third clamping portion rotating mechanism for driving the third clamping portion of the third clamping piece to rotate. The third clamping portion can be driven to rotate by the third clamping portion rotating mechanism, which can drive the edge leather block clamped between the third clamping pieces to rotate so as to adjust the position of each edge.

[0292] In some embodiments, in the third edge leather block clamping device, the third bearing mount is arranged at the bottom, the third clamping seat of the third edge leather block clamp is arranged above the third bearing mount, and the at least one pair of third clamping members are arranged on the third clamping seat and arranged upward. After the at least one pair of third clamping members clamp the edge leather block, the uppermost edge portion can be fully exposed, and the uppermost edge portion is used as the edge portion to be chamfered. Therefore, the chamfering device at the chamfering position may include at least one chamfering grinder (for example, a chamfering grinder or two parallel chamfering grinders), and the chamfering surface of the at least one chamfering grinder is horizontally facing downward. After the uppermost edge portion is chamfered by the chamfering grinder and completed, the third clamping portion can be driven to rotate by the third clamping portion rotation mechanism to drive the edge leather block to rotate to expose other edges. The other exposed edges can still be chamfered by the chamfering grinder. In this way, when the chamfering grinder does not change its position, the edge leather block is driven to rotate by the third clamping part rotating mechanism to complete the chamfering operation of each edge portion of the edge leather block.

[0293] In some embodiments, in the third edge leather block clamping device, the third bearing mount is arranged at the bottom and extends upward or is arranged at the side, the third clamping seat of the third edge leather block clamp is arranged at one side of the third bearing mount, and the at least one pair of third clamping members are arranged at the third clamping seat and are arranged to the left or right. After the at least one pair of third clamping members clamp the edge leather block, the edge portion located at the far left (or far right) can be fully exposed, and the edge portion located at the far left (or far right) is used as the edge portion to be chamfered. Therefore, the chamfering device at the chamfering position may include at least one chamfering grinder (for example, a chamfering grinder or two parallel chamfering grinders), and the chamfering surface of the at least one chamfering grinder is horizontally facing right (or horizontally facing left). After the leftmost (or far right) edge portion is chamfered by the chamfering grinder and completed, the third clamping portion can be driven to rotate by the third clamping portion rotation mechanism to drive the third clamping portion to rotate, so as to expose other edges. The other exposed edges can still be chamfered by the chamfering tool. In this way, when the chamfering tool does not change its position, the edge leather block is driven to rotate by the third clamping part rotating mechanism to complete the chamfering of each edge of the edge leather block.

[0294] In some embodiments, the third clamping portion is a multi-point contact clamping head. It is understandable that the contact method between the multi-point contact clamping head and the end face of the edge skin block is not limited to point contact. For example, the third clamping portion has a plurality of protrusions to contact the end face of the edge skin block, wherein each protrusion can be in surface contact with the end face of the edge skin block.

[0295] In some embodiments, a portion of a pair of third clamping parts in the pair of third clamping members for contacting the edge skin block is configured as a rigid structure to prevent the clamped edge skin block from being disturbed during the chamfering operation and affecting the processing accuracy.

[0296] In practical applications, the third clamping portion rotating mechanism may include a rotatable structure provided on two third clamping portions of a pair of third clamping members and a driving source for driving at least one of the two rotatable structures to rotate.

[0297] In some embodiments of the present application, the third clamping part of the third clamping member can be configured as a rotatable truncated cone, the circular plane of the truncated cone contacts the end face of the edge leather block, and remains relatively still with the end face of the edge leather block after being pressed against the end face of the edge leather block. The third clamping part also includes a locking structure, and the third clamping part is in a locked state when chamfering a selected plane. When switching between different chamfers, the third clamping part rotates along the center of the truncated cone driven by the third clamping part rotation mechanism.

[0298] In some implementations, the third clamping portion of the third clamping member includes a rotatable truncated cone and a series of protruding contacts arranged on the truncated cone, wherein each contact has a contact plane for contacting the clamped edge leather block, and the truncated cone rotates driven by the rotation mechanism of the third clamping portion. Regarding the contacts, in some implementations, the protruding length of the contacts, that is, the position of the horizontal line, is adjustable, so that in the process of clamping the edge leather block, for the edge leather block with a lower end surface flatness, the protruding length of the contacts can be adjusted according to the end surface of the edge leather block, so that the contact surface of each contact is in a close contact state with the end surface of the edge leather block. The protruding length is the length of the horizontal line from the circular plane of the truncated cone to the contact plane of the contact.

[0299] The third clamping part rotation mechanism may be arranged on one of the third clamping parts in a pair of third clamping parts, so as to drive the third clamping part of the third clamping parts and the clamped edge leather piece to rotate; or, the third clamping part rotation mechanism may be arranged on two third clamping parts in a pair of third clamping parts, and coordinately control the two third clamping parts of the third clamping parts to rotate at the same angle and direction. The driving source in the third clamping part rotation mechanism may be, for example, a driving motor.

[0300] Regarding the chamfering device, the chamfering device includes a chamfering frame and a chamfering unit movably arranged on the chamfering frame or a pair of chamfering units arranged opposite to each other, and each chamfering unit has at least one chamfering grinder. In some embodiments, the edge skin block placed on the third edge skin block clamping device only reveals one edge portion, or the edge skin block reveals multiple edges but only one edge portion needs to be chamfered at a time, then the chamfering device may include a chamfering frame and a chamfering unit movably arranged on the chamfering frame, and the chamfering unit corresponds to the exposed edge portion or the edge portion that needs to be chamfered. In some embodiments, the edge skin block placed on the third edge skin block clamping device at least reveals a pair of edges (that is, two edges adjacent to a certain side surface) and both of the pair of edges can be chamfered, then the chamfering device may include a chamfering frame and a pair of chamfering units movably arranged on the chamfering frame at an angle, and the pair of chamfering units corresponds to the exposed pair of edges.

[0301] For a certain chamfering unit, the chamfering unit includes a chamfering support movably arranged on the chamfering frame and at least one chamfering grinding tool arranged on the chamfering support.

[0302] In some embodiments, the chamfering surface of the chamfering grinder is horizontally downward or horizontally upward (if it is a pair of chamfering grinders, the chamfering surface of the chamfering grinder is angled downward or angled upward), and the chamfering unit includes a chamfering support vertically movably arranged on the chamfering frame and at least one chamfering grinder arranged on the chamfering support, and the at least one chamfering grinder is used to chamfer the edges of the edge skin block clamped by the third edge skin block clamping device.

[0303] The chamfer support can be arranged on the chamfer frame in the vertical direction (i.e., the third direction) through the chamfer support lifting mechanism.

Therefore, in some embodiments, the chamfering device is a mobile chamfering device and the third side leather block clamping device is a fixed side leather block clamping device.

[0309] Taking the mobile chamfering device as an example, the chamfering device includes a chamfering frame travel mechanism, and the chamfering frame and the chamfering unit provided thereon are driven to move along the second direction by the chamfering frame travel mechanism.

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

[0313] When the chamfering device is used to chamfer the edges of the side skin block at the chamfering area, the chamfering frame and its chamfering unit are driven by the chamfering frame travel mechanism to move in the second direction to achieve relative movement with the side skin block clamped by the third side skin block clamping device at the chamfering area so that the chamfering grinder in the chamfering unit can chamfer the edges of the side skin block clamped by the third side skin block clamping device at the chamfering area.

[0314] Taking the movable edge skin block clamping device as an example, the third edge skin block clamping device includes a third clamping and traveling mechanism, and the third edge skin block clamping device and the edge skin block clamped by it are driven to move along the second direction by the third clamping and traveling mechanism.

[0315] In some embodiments, the third clamping and traveling mechanism includes: a third clamping and traveling guide rail and a third clamping and traveling drive unit, wherein the third clamping and traveling guide rail is arranged on a third bearing mounting seat along the second direction, and the third clamping and traveling drive unit is used to drive the third side skin block clamp and the side skin block clamped therein to move along the third clamping and traveling guide rail.

[0316] In some embodiments, the third clamping and traveling driving unit includes a third clamping and traveling rack, a driving gear, and a driving source. The third clamping and traveling rack is arranged on the third bearing mounting seat along the second direction, parallel to the third clamping and traveling guide rail.

[0318] When the chamfering device is used to chamfer the edges of the edge leather block at the chamfering area, the third edge leather block clamp and the edge leather block clamped by it are driven by the third clamping and moving mechanism to move in the second direction to achieve relative movement with the chamfering unit in the chamfering device so that the chamfering grinder in the chamfering unit can chamfer the edges of the third edge leather block clamp and the edge leather block clamped by it.

[0319] The third edge leather block clamping device and chamfering device described above may still have other variations.

[0320] The edge leather block grinding device of the present application includes an edge leather block supporting device. In some embodiments, the edge leather block supporting device supports the edge leather block so that the edge leather block is placed horizontally and its length direction is consistent with the first direction. In some embodiments, the edge leather block supporting device supports the edge leather block so that the edge leather block is placed horizontally and its length direction is consistent with the second direction.

[0321] In the following description, an example is taken in which the edge skin block is horizontally placed at the chamfered area and the length direction of the edge skin block is consistent with the second direction.

[0322] The edge skin block supporting device may include an edge skin block supporting platform, which is arranged on the machine base along the second direction and located at the chamfered area, and is used to support at least one edge skin block placed horizontally. If one edge skin block is placed horizontally on the edge skin block supporting platform as an example, the length of the edge skin block supporting platform is related to the length of the edge skin block, and the width of the edge skin block supporting platform may be related to the width of the edge skin block. If two edge skin blocks are placed horizontally on the edge skin block supporting platform in a left-right parallel manner as an example, the length of the edge skin block supporting platform matches the length of the edge skin block, and the width of the edge skin block supporting platform matches the sum of the widths of the two edge skin blocks.

[0323] In some embodiments, the edge skin block supporting device supports the edge skin block by placing the edge skin block in a manner that one side surface of the edge skin block (the side surface may be referred to as the supporting bottom surface) is in contact with the slope supporting platform, so that the edge skin block can be placed horizontally and at least the top surface opposite to the supporting bottom surface and two edges adjacent to the top surface are exposed.

[0324] In order to ensure that the edge skin block can be placed firmly on the edge skin block supporting platform, the edge skin block supporting device may further include an edge skin block positioning mechanism, which is used to position the edge skin block supported by the edge skin block supporting platform. In this way, when the edge skin block supported by the edge skin block supporting platform is subjected to surface grinding by the surface grinding device, the edge skin block positioning mechanism may be used to position the edge skin block supported by the edge skin block supporting platform, so as to avoid relative displacement between the edge skin block and the edge skin block supporting platform during the surface grinding operation, thereby affecting the surface grinding quality. In certain embodiments, the edge skin block positioning mechanism may be, for example, an edge skin clamping mechanism, which is disposed at the front and rear ends of the edge skin block supporting platform along the length direction, and is used to clamp the two ends of the edge skin block, or the edge skin clamping mechanism is disposed at the left and right sides of the edge skin block supporting platform in the relative length direction, and is used to clamp the two sides of the edge skin block.

[0325] Since the edge skin block supporting device can support the edge skin block and expose the top surface opposite to the supporting bottom surface and two edges adjacent to the top surface, the chamfering device may include a chamfering frame and at least one pair of chamfering units movably arranged on the chamfering frame, and the at least one pair of chamfering units corresponds to the exposed pair of edges. Each chamfering unit has at least one chamfering grinder.

[0326] For a certain chamfering unit, the chamfering unit includes a chamfering support movably arranged on the chamfering frame and at least one chamfering grinding tool arranged on the chamfering support.

[0328] The chamfer support can be arranged on the chamfer frame in the vertical direction (i.e., the third direction) through the chamfer support lifting mechanism. The chamfer support can be lifted and lowered relative to the chamfer frame by using the chamfer support lifting mechanism. In some embodiments, the chamfer support lifting mechanism may include: a chamfer lifting guide rail and a chamfer lifting drive unit, wherein the chamfer lifting guide rail is arranged on the chamfer frame in the vertical direction, and the chamfer lifting drive unit is used to drive the chamfer support and at least one chamfering tool arranged thereon to move up and down along the chamfer lifting guide rail. In some embodiments, the chamfer lifting drive unit may include a chamfer lifting screw rod and a driving source, wherein the chamfer lifting screw rod is arranged in the vertical direction and is associated with the chamfer support, and the driving source is used to drive the chamfer lifting screw rod to rotate so that the associated chamfer support and at least one chamfering tool arranged thereon can move up and down along the chamfer lifting guide rail. In some examples, the driving source may be, for example, a driving motor. In some embodiments, the chamfer support lifting mechanism may include: a chamfer lifting rack, a driving gear, and a driving source, wherein the chamfer lifting rack is vertically arranged on the chamfering frame and is parallel to the chamfer lifting guide rail.

The driving source is associated with the driving wheel and is used to drive the driving wheel to rotate so that the associated chamfer support and at least one chamfering tool arranged thereon are moved up and down along the chamfer lifting guide rail. In some examples, the driving source may be, for example, a driving motor.

[0329] In addition, the chamfering supports in the at least one pair of chamfering units may also be shared. For example, the first chamfering support in the first chamfering unit and the second chamfering support in the second chamfering unit in the pair of chamfering units may share the same chamfering support, and the shared chamfering support drives the pair of chamfers to move vertically on the chamfering frame through the chamfering support lifting mechanism.

[0330] Taking a pair of chamfering units as an example, the pair of chamfering units can be set at an angle. For example, in a certain example, the chamfering tool in the first chamfering unit is at a 45° angle to the horizontal line or the vertical direction, and the chamfering tool in the second chamfering unit is at a 45° angle to the horizontal line or the vertical direction. Of course, the above-mentioned angle is not limited to this. In different embodiments, other angles can be selected. For example, the inclination angle can be any angle between 40° and 60°, and is not limited to integer degrees.

[0331] The chamfering tool comprises at least one grinding wheel. In some embodiments, the grinding wheel is a rough grinding wheel or a fine grinding wheel. In some embodiments, the chamfering tool comprises a rough grinding wheel and a fine grinding wheel nested in each other, for example, the rough grinding wheel is nested in the fine grinding wheel, or, the fine grinding wheel is nested in the rough grinding wheel.

[0355] The first type of grinding device is used to perform grinding operation on a pair of first side surfaces of the edge leather block at the first type of grinding area. Specifically, through the relative movement of the first type of grinding device and the first edge leather block clamping device, for example, at least one first grinding tool in the first type of grinding device is used to perform grinding operation on a first side surface exposed in the edge leather block clamped by the first edge leather block clamping device. After the grinding operation on one first side surface is completed, the edge leather block can be rotated by the first edge leather block clamping device to change the position of the edge leather block to expose another first side surface, and the at least one first grinding tool in the grinding device is used to continue to perform grinding operation on the other first side surface until the grinding operation on a pair of first side surfaces is completed; or, at least one pair of first grinding tools in the first type of grinding device is used to perform grinding operation on a pair of first side surfaces exposed in the edge leather block clamped by the first edge leather block clamping device.

[0356] The side leather block that has completed the grinding operation on a pair of sides is transferred to the second type of grinding area by using a transfer device so that the end of the side leather block along the length direction can be clamped by a second side leather block clamping device.

[0357] The second type of grinding device is used to perform grinding operation on a pair of second side surfaces of the edge leather block at the second type of grinding area. Specifically, through the relative movement of the second type of grinding device and the second edge leather block clamping device, for example, at least one second grinding tool in the second type of grinding device is used to perform grinding operation on a second side surface exposed in the edge leather block clamped by the second edge leather block clamping device. After the grinding operation on one second side surface is completed, the edge leather block can be rotated by the second edge leather block clamping device to change the position of the edge leather block to expose another second side surface, and the at least one second grinding tool in the grinding device is used to continue to perform grinding operation on the other second side surface until the grinding operation on a pair of second side surfaces is completed; or, at least one pair of second grinding tools in the second type of grinding device is used to perform grinding operation on a pair of second side surfaces exposed in the edge leather block clamped by the second edge leather block clamping device.

[0358] The edge leather block that has completed the surface grinding operation is transferred by the transfer device and placed at the chamfering area so that the edge leather block is clamped by the third edge leather block clamping device at the end along the length direction, and the edge leather block to be ground is transferred by the loading conveying device and the transfer device and placed at the surface grinding area so that the edge leather block is clamped by the first edge leather block clamping device at the end along the length direction.

The chamfering device is used to chamfer the four edges of the edge leather block at the chamfering position, which may include: through the relative movement of the chamfering device and the third edge leather block clamping device, at least one chamfering grinder in the chamfering device performs a chamfering operation on at least one edge portion exposed in the edge leather block clamped by the third edge leather block clamping device, after completing the chamfering operation of at least one edge portion, the third edge leather block clamping device may be used to rotate the edge leather block to change the position of the edge leather block to expose other unchamfered edges, and at least one chamfering grinder in the chamfering device continues to chamfer the new edge portion until the chamfering operation of the four edges is completed. Alternatively, through the relative movement of the chamfering device and the edge leather block supporting device, a pair of chamfering units in the chamfering device chamfers the two exposed edges of the edge leather block supported by the edge leather block supporting device at the chamfering area. After the chamfering of the two edges is completed, the edge leather block can be rotated by the transfer device to change the position of the edge leather block to expose the other two unchamfered edges, and the pair of chamfering grinders in the chamfering device continue to chamfer the two newly exposed edges to complete the chamfering of the four edges. The surface grinding operation of the four side surfaces of the edge leather block at the surface grinding area by the surface grinding device is referred to the above description and will not be repeated here.

[0360] After the chamfering operation of the edge skin block is completed, the edge skin block after the chamfering operation is transferred to the unloading conveying device by using the transfer device and then unloaded.

For example, the grinding device of the edge leather block grinding equipment is located at the grinding area, and the range of the grinding area is the range occupied by the grinding device in the process of completing the grinding operation; similarly, the chamfering device of the edge leather block grinding equipment is located at the chamfering area, and the range of the chamfering area is the range occupied by the chamfering device in the process of completing the chamfering operation. The shape of the processing platform can be determined according to the machine base, or it can be determined jointly according to the processing needs of the machine base and the grinding device and the chamfering device.

[0366] In certain embodiments, each functional area is arranged along a first direction or along a second direction, wherein, in the following description, the first direction refers to the length direction of the edge leather block grinding equipment, and the second direction is perpendicular to the first direction and refers to the width direction of the edge leather block grinding equipment. For example, when the edge leather block grinding equipment includes a grinding area and a chamfering area, the grinding area and the chamfering area can be arranged in parallel along the first direction or arranged in sequence along the second direction. Taking the arrangement in parallel along the first direction as an example, when the edge leather block grinding equipment includes a loading and unloading area, a grinding area, and a chamfering area, the loading and unloading area, the grinding area, and the chamfering area can be arranged in parallel along the first direction (for example, in the form of a loading and unloading area, a grinding area, and a chamfering area, or in the form of a grinding area, a loading and unloading area, and a chamfering area, etc.). When the edge leather block grinding equipment includes a loading position, a grinding position, a chamfering position, and an unloading position, the loading position, the grinding position, the chamfering position, and the unloading position are arranged in parallel along a first direction (for example, in the form of a loading position, a grinding position, a chamfering position, and an unloading position, or in the form of a grinding position, a loading position, an unloading position, and a chamfering position, etc.).
