DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0035] The plurality of in the present application refers to two or more.

[0036] In the description of the embodiments of the present application, the words "exemplary" or "for example" are used to mean as an example, illustration, or description. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the words "exemplary" or "for example" are used in the specific manner to present the relevant concept.

[0037] Please refer to Figure 1 , Figure 1 An embodiment of the present application provides a processing device 100. The processing device 100 can accommodate a plurality of sheet materials 200 and perform plating processing on the plurality of sheet materials 200.

[0038] In an embodiment of the present application, the type of the sheet material 200 is not specifically limited. For example, the sheet material 200 can be applied to a lithium battery, and the sheet material 200 can be a metal foil.

[0039] In an embodiment of the present application, the material of the film formed after plating on the sheet material 200 is not specifically limited. For example, after plating on the sheet material 200, a silicon-containing layer can be formed on both sides of the sheet material 200. The material of the silicon-containing layer includes silicon and / or a silicon-containing compound. The silicon-containing compound can be a compound of silicon and nitrogen, carbon, boron, phosphorus, oxygen, magnesium, aluminum, germanium, tin, nickel, copper, and combinations thereof.

[0040] In an embodiment, the processing device 100 can include a reaction furnace 101 and a clamping device 102. The clamping device 102 can clamp a plurality of sheet materials 200. The clamping device 102 can be moved into or out of the reaction furnace 101 synchronously with the sheet materials 200 clamped thereby. The reaction furnace 101 can be supplied with a reaction gas, and the sheet materials 200 located in the reaction furnace 101 can be heated to react with the reaction gas and complete plating.

[0041] Please refer to Figure 2 and Figure 3 , Figure 2 An embodiment of the present application provides a clamping device 102. In an embodiment of the present application, the length direction of the processing device 100 and the clamping device 102 can be defined as a first horizontal direction, the width direction can be defined as a second horizontal direction, and the height direction can be defined as a vertical direction. For example, the first horizontal direction can be the X direction in Figure 1 and Figure 2 , the second horizontal direction can be the Y direction in Figure 2 , and the vertical direction can be the Z direction in Figure 1 and Figure 2 ; wherein the side away from the X direction is a first side in the first horizontal direction, the side toward the X direction is a second side in the first horizontal direction, the direction from the first side toward the second side (i.e., the direction of the X arrow) is a positive direction, and the direction from the second side toward the first side (i.e., the direction away from the X arrow) is a negative direction.

[0042] Similarly, the two sides away from and toward the Y-direction arrow are the first side and the second side in the second horizontal direction, and the direction of the first side toward the second side and the direction of the second side toward the first side are the positive direction and the reverse direction, respectively. The two sides away from and toward the Z-direction arrow are the first side and the second side in the vertical direction, and the direction of the first side toward the second side and the direction of the second side toward the first side are the positive direction and the reverse direction, respectively.

[0043] In the drawings of the present application, the side where A1 is located indicates the first side in the first horizontal direction, the side where B1 is located indicates the second side in the first horizontal direction, the side where A2 is located indicates the first side in the second horizontal direction, and the side where B2 is located indicates the second side in the second horizontal direction.

[0044] In the embodiments of the present application, the principle of the processing equipment 100 processing the sheet-shaped material 200 through the reaction furnace 101 is not specifically limited. For example, the processing equipment 100 can perform film plating processing on the sheet-shaped material 200 according to the principle of plasma enhanced chemical vapor deposition (PECVD).

[0045] Please refer to Figure 4 and Figure 5 In some embodiments, the clamping device 102 can include a clamping mechanism 10. At least one set of clamping mechanisms 10 can be provided in the clamping device 102, the number of clamping mechanisms 10 in each set of clamping mechanisms 10 is two, and the two clamping mechanisms 10 are spaced apart in the first horizontal direction.

[0046] Each clamping mechanism 10 includes a fixed seat 11, a connecting seat 12, two compression rollers 13, and two gears 14. The connecting seat 12 is spaced apart from the fixed seat 11 in the vertical direction. The two compression rollers 13 are located between the connecting seat 12 and the fixed seat 11. The axial direction of the two compression rollers 13 coincides with the vertical direction, and the two compression rollers 13 are rotatably connected to the connecting seat 12 and the fixed seat 11. The two compression rollers 13 are arranged in the second horizontal direction and can abut against two surfaces of a sheet-shaped material 200 in the second horizontal direction, thereby clamping the sheet-shaped material 200. The two gears 14 are located on the side of the connecting seat 12 away from the fixed seat 11, and the two gears 14 correspond to the two compression rollers 13 one-to-one. Each gear 14 is coaxially fixed with the corresponding compression roller 13. The two gears 14 are meshed, so that the two gears 14 can synchronously rotate in opposite circumferential directions, thereby causing the two compression rollers 13 to synchronously rotate in opposite circumferential directions. In each clamping mechanism 10, at least one compression roller 13 can be connected to a driving member (not shown in the figure), and the driving member can drive the compression roller 13 to rotate, thereby causing the two compression rollers 13 in one clamping mechanism 10 to synchronously rotate.

[0047] In the embodiments of the present application, the fixing manner when fixedly installed and fixedly connected is not specifically limited. For example, the fixing manner can be, but is not limited to, screw fixing, bolt fixing, welding fixing, integral forming fixing, etc.

[0048] It can be understood that the rotatable connection can be achieved by a rotating connecting piece, and the connecting manner can make two components relatively rotate. In the embodiments of the present application, the type of the rotating connecting piece is not specifically limited. For example, the rotating connecting piece can be, but is not limited to, a shaft coupling, a bearing, a hinge, etc.

[0049] For example, the compression roller 13 and the gear 14 can be installed on the same pin shaft through a key connection, and the pin shaft can be connected to the connecting seat 12 through a bearing, so as to realize coaxial fixing of the compression roller 13 and the gear 14, and rotatable connection between the compression roller 13 and the connecting seat 12.

[0050] In the embodiments of the present application, the material of the compression roller 13 is not specifically limited. For example, the material of the part of the compression roller 13 used for abutting against the sheet material 200 can be a flexible material such as rubber or silicone. At this time, the two compression rollers 13 are kept in abutment before clamping the sheet material 200, and the two compression rollers 13 have a pre-tightening force. When the sheet material 200 abuts against the position contacted by the two compression rollers 13, the two compression rollers 13 can rotate, and the sheet material 200 enters between the two compression rollers 13 under the action of the friction force of the two compression rollers 13, so as to realize abutment and clamping of the two compression rollers 13 to the sheet material 200.

[0051] For another example, the compression roller 13 can be a metal material. Anti-skid lines are arranged on the peripheral wall of the compression roller 13. When the sheet material 200 enters between the two compression rollers 13, the anti-skid lines on the two compression rollers 13 can abut against the sheet material 200, and then the compression roller 13 rotates. Under the action of the friction force between the anti-skid lines and the sheet material 200, the sheet material 200 can enter between the two compression rollers 13, so as to realize abutment and clamping of the two compression rollers 13 to the sheet material 200.

[0052] It can be understood that in the same set of clamping mechanisms 10, the two compression rollers 13 located on the first side in the first horizontal direction can clamp the first side of the sheet material 200 in the first horizontal direction, and the two compression rollers 13 located on the second side can clamp the second side of the sheet material 200 in the first horizontal direction.

[0053] When the two pressing rollers 13 in one clamping mechanism 10 clamp the sheet material 200, the pressing roller 13 on the first side in the second horizontal direction rotates counterclockwise, and the pressing roller 13 on the second side rotates clockwise, which can drive the sheet material 200 to move in the opposite direction of the first horizontal direction; the pressing roller 13 on the first side in the second horizontal direction rotates clockwise, and the pressing roller 13 on the second side rotates counterclockwise, which can drive the sheet material 200 to move in the positive direction of the first horizontal direction. In this way, in the same group of clamping mechanisms 10, the two pressing rollers 13 on the first side in the first horizontal direction drive the first side of the sheet material 200 to move in the positive direction of the first horizontal direction, and the two pressing rollers 13 on the second side drive the sheet material 200 to move in the opposite direction of the first horizontal direction, which can realize the tensioning of the sheet material 200 while clamping the sheet material 200.

[0054] For example, the clockwise direction can be the CW direction shown in Figure 5 , and the counterclockwise direction can be the CCW direction shown in Figure 5 .

[0055] It can be understood that the plating process of the sheet material 200 needs to be carried out in a high-temperature environment (for example, 500-600 degrees Celsius). The increase in temperature will cause the sheet material 200 to elongate, which will increase the length of the sheet material 200 in the first horizontal direction. The two clamping mechanisms 10 in each group of clamping mechanisms 10 can drive the sheet material 200 to move in the first horizontal direction by rotating the pressing rollers 13 while clamping the two sides of the sheet material 200 in the first horizontal direction, so that the two sides of the sheet material 200 in the first horizontal direction maintain a tendency to move away from each other, which realizes the tensioning of the sheet material 200. In this way, the sheet material 200 can be prevented from wrinkling or deforming during the process. In this way, the processing effect of the sheet material 200 can be improved, and the yield of the processed sheet material 200 can be improved.

[0056] In some embodiments, the clamping device 102 can further include a base 20. The fixing seat 11 can be mounted on the base 20. The base 20 can be supported on a movable carrier (not shown) or mounted on a hoisting frame (not shown), so that the clamping device 102 is supported on the movable carrier or mounted on the hoisting frame. The clamping device 102 can be moved into or out of the reaction furnace 101 by the movable carrier or the hoisting frame.

[0057] In the embodiments of the present application, the number of groups of clamping mechanisms 10 in the clamping device 102 is not specifically limited. When the clamping device 102 includes multiple groups of clamping mechanisms 10, the multiple groups of clamping mechanisms 10 can be arranged at intervals in the second horizontal direction and are all mounted on the base 20. Each group of clamping mechanisms 10 can clamp one sheet material 200.

[0058] In some embodiments, the clamping device 102 can further comprise a plurality of limiting mechanisms 30. The number of limiting mechanisms 30 is the same as the number of clamping mechanisms 10, and each limiting mechanism 30 corresponds to one clamping mechanism 10. The limiting mechanism 30 can limit the rotation direction of two gears 14 in the same clamping mechanism 10, i.e., can block the rotation of each gear 14 in one circumferential direction (e.g., counterclockwise direction or clockwise direction), so that the gear 14 can only rotate in the other circumferential direction; in this way, each limiting mechanism 30 can make one side of the sheet-shaped material 200 clamped by the corresponding clamping mechanism 10 moveable in one linear direction (e.g., positive direction or negative direction of the first horizontal direction), and limit the movement of the one side of the sheet-shaped material 200 in the opposite linear direction.

[0059] For example, the limiting mechanism 30 corresponding to the clamping mechanism 10 located at the first side in the first horizontal direction can make the gear 14 located at the first side in the second horizontal direction in the clamping mechanism 10 not rotatable in the clockwise direction, but only rotatable in the counterclockwise direction; the gear 14 located at the second side not rotatable in the counterclockwise direction, but only rotatable in the clockwise direction, so that the first side of the sheet-shaped material 200 clamped by the clamping mechanism 10 is only moveable in the negative direction of the first horizontal direction, but not in the positive direction.

[0060] The limiting mechanism 30 corresponding to the clamping mechanism 10 located at the second side in the first horizontal direction can make the gear 14 located at the first side in the second horizontal direction in the clamping mechanism 10 not rotatable in the counterclockwise direction, but only rotatable in the clockwise direction; the gear 14 located at the second side not rotatable in the clockwise direction, but only rotatable in the counterclockwise direction, so that the second side of the sheet-shaped material 200 clamped by the clamping mechanism 10 is only moveable in the positive direction of the first horizontal direction, but not in the negative direction.

[0061] In this way, the first side and the second side of the sheet-shaped material 200 in the first horizontal direction can maintain a tendency to move away from each other or move away from each other, and cannot move close to each other; the movement of the sheet-shaped material 200 in the first horizontal direction can be reduced, so that the sheet-shaped material 200 cannot move close to each other during the coating process, thereby reducing the possibility of the sheet-shaped material 200 being wrinkled or deformed, and improving the coating effect of the sheet-shaped material 200.

[0062] Please refer to Figure 6 In some embodiments, each limiting mechanism 30 can comprise a limiting seat 31, a blocking piece 32, and a first elastic piece 33.

[0063] The limiting seat 31 is located on the side of the corresponding gear 14 away from the connecting seat 12. The limiting seat 31 can include a fixed part 311, a moving part 312, and a protrusion 313. The fixed part 311 is relatively fixed with the connecting seat 12 and the fixed seat 11, so that the limiting seat 31 is relatively fixed with the connecting seat 12 and the fixed seat 11. The fixed part 311 is provided with a receiving groove 3111 penetrating the fixed part 311 in the vertical direction and extending in the first horizontal direction. The receiving groove 3111 is provided with a plurality of limiting grooves 3112 on the opposite sidewalls in the second horizontal direction, and the limiting grooves 3112 on the same sidewall in the second horizontal direction are arranged at intervals in the first horizontal direction.

[0064] The moving part 312 is movably connected to the receiving groove 3111 in the vertical direction and the first horizontal direction. The protrusion 313 is integrally formed on both sides of the moving part 312 in the second horizontal direction, and each protrusion 313 is movably connected to the limiting groove 3112 on the same side in the second horizontal direction in the vertical direction. The protrusion 313 can enter the corresponding limiting groove 3112, thereby limiting the movement of the moving part 312 in the first horizontal direction. The moving part 312 is provided with two sliding grooves 3121. The two sliding grooves 3121 are arranged at intervals in the first horizontal direction and penetrate the moving part 312 in the vertical direction. The inner wall of each sliding groove 3121 includes a first sidewall 3122 and a second sidewall 3123. The first sidewall 3122 and the second sidewall 3123 are arranged opposite to each other in the first horizontal direction. In the two sliding grooves 3121, the sidewall of the inner wall of each sliding groove 3121 closer to the other sliding groove 3121 in the first horizontal direction is the first sidewall 3122, and the sidewall farther away from the other sliding groove 3121 is the second sidewall 3123. In the two sliding grooves 3121, the distance between the two second sidewalls 3123 is greater than the distance between any first sidewall 3122 and the second sidewall 3123 of the other sliding groove 3121, and the distance between the two first sidewalls 3122 is less than the distance between any first sidewall 3122 and the second sidewall 3123 of the other sliding groove 3121.

[0065] The number of the blocking pieces 32 can be two, and the two blocking pieces 32 correspond to the two sliding grooves 3121 respectively. Each blocking piece 32 can include a movable block 321 and an extension rod 322. The movable block 321 can be accommodated in the corresponding sliding groove 3121 and is movably connected to the sliding groove 3121 in the first horizontal direction. A first elastic piece 33 is located in the sliding groove 3121 and abuts against the corresponding movable block 321 and the second side wall 3123 of the sliding groove 3121. The first elastic piece 33 can drive the corresponding movable block 321 to be close to the first side wall 3122 of the sliding groove 3121. The extension rod 322 is fixedly connected to one side of the movable block 321 facing the compression roller 13. The extension rod 322 extends in the vertical direction, and the bottom of the extension rod 322 can be at the same height as the gear 14 in the same clamping mechanism 10. In the same limiting mechanism 30, the two extension rods 322 can be located on both sides of the meshing positions of the corresponding two gears 14 in the first horizontal direction respectively.

[0066] A plurality of protruding teeth 141 are protruded on the peripheral wall of each gear 14. The two extension rods 322 can move synchronously with the movable block 321 and the moving part 312, so as to adjust the distance between the two extension rods 322 and the two gears 14 in the first horizontal direction and the second horizontal direction. Each extension rod 322 can block the protruding teeth 141 of the gear 14 when located at a specified position, so that the rotation of the gear 14 in the first circumferential direction pushes the movable block 321 connected to the extension rod 322 to abut against the corresponding first side wall 3122, so that the movable block 321 cannot be moved, so that the gear 14 cannot rotate in this circumferential direction; at this time, when the gear 14 rotates in the second circumferential direction, the extension rod 322 can be pushed to move, so that the corresponding movable block 321 of the extension rod 322 pushes the corresponding first elastic piece 33 to compress, so that the movable block 321 is close to the corresponding second side wall 3123, so that the extension rod 322 can be close to the second side wall 3123 in the first horizontal direction synchronously, that is, the extension rod 322 can be pushed by the rotating gear 14, so that the gear 14 can rotate in the current circumferential direction. In the process of rotating the gear 14, the two gears 14 can not abut against the other extension rod 322, that is, the other extension rod 322 is spaced apart from the protruding teeth 141 of the two gears 14, so as not to affect the rotation of the gear 14. Among them, by accommodating the protrusions 313 in different limiting grooves 3112, the extension rod 322 can be located at a specified position or not at a specified position; in the two extension rods 322 in the same limiting mechanism 30, only one extension rod 322 can be located at a specified position in the same state; when one extension rod 322 is located at a specified position, the other extension rod 322 is not located at a specified position; and the two extension rods 322 can not be located at a specified position at the same time.

[0067] It can be understood that the first circumferential direction and the second circumferential direction of each gear 14 can be clockwise direction and counterclockwise direction respectively, or counterclockwise direction and clockwise direction respectively, and embodiments of the present application do not limit this.

[0068] It can be understood that the initial position of the blocking piece 32 in the first horizontal direction can be changed by the movement of the moving part 312 in the limiting mechanism 30, that is, one of the two extension rods 322 in the same limiting mechanism 30 can enter the specified position or both of the two extension rods 322 do not enter the specified position. The worker can manually adjust the position of the moving part 312 according to the position (for example, the first side or the second side) of the clamping mechanism 10 corresponding to the limiting mechanism 30 in the first horizontal direction, so that one of the extension rods 322 in the corresponding blocking piece 32 enters the specified position, so that the two gears 14 corresponding to the blocking piece 32 can only rotate in the defined circumferential direction, and then the two compression rollers 13 corresponding to the blocking piece 32 can only rotate in the defined direction, so that one side of the sheet-shaped material 200 clamped by the two compression rollers 13 can only move in the defined straight line direction (for example, the positive direction or the negative direction of the first horizontal direction) in the first horizontal direction. In this way, the first side of the sheet-shaped material 200 in the first horizontal direction can only move in the negative direction of the first horizontal direction, and the second side can only move in the positive direction of the first horizontal direction, so that the rotation of the compression roller 13 can clamp and tension the sheet-shaped material 200, and the sheet-shaped material 200 cannot be loosened from the compression roller 13. It can reduce the situation that the sheet-shaped material 200 falls off from the compression roller 13 or wrinkles or deforms during processing, and can improve the processing effect of the sheet-shaped material 200 and improve the yield of the processed sheet-shaped material 200.

[0069] After the processing of the sheet-shaped material 200 is completed, the worker can move the moving part 312 to make the two extension rods 322 not be located in the specified position, so that the two gears 14 and the two compression rollers 13 can rotate in any direction, facilitating the collection of the sheet-shaped material 200 after processing by the worker.

[0070] By adjusting the position of the moving part 312, the direction in which the sheet-shaped material 200 clamped by the clamping mechanism 10 corresponding to the limiting mechanism 30 can be moved can be adjusted. In this way, the worker can assemble the limiting mechanism 30 and the clamping mechanism 10 without considering the direction in which the limiting mechanism 30 limits the movement when assembling the clamping device 102, and then move the corresponding moving part 312 to adjust the direction in which the limiting mechanism 30 limits the movement, which can improve the convenience of assembling the clamping device 102.

[0071] For example, as shown in FIG. 6, the moving part 312 can be a rotating shaft, and the extension rod 322 can be a gear. Figure 5 and 6As shown, the protrusions 313 can be provided in two groups, and the two groups of protrusions 313 are spaced apart in the second horizontal direction. The two groups of protrusions 313 are respectively provided on the two sides of the moving part 312 in the second horizontal direction. The number of protrusions 313 in each group is two, and the two protrusions 313 are spaced apart in the first horizontal direction.

[0072] Please refer to Figure 7 and Figure 8 The limiting grooves 3112 can be provided in two groups, and the two groups of limiting grooves 3112 are spaced apart in the second horizontal direction. The two groups of limiting grooves 3112 are respectively located on the two side walls of the accommodating groove 3111 in the second horizontal direction. The number of limiting grooves 3112 in each group can be six, and each protrusion 313 is provided with three limiting grooves 3112. The three limiting grooves 3112 in the positive direction of the first horizontal direction are sequentially limiting groove 3112a, limiting groove 3112b and limiting groove 3112c. When the protrusion 313 is located in the limiting groove 3112b, the two extension rods 322 are not located in the specified position, and the two extension rods 322 are spaced apart from all the protrusions 141 of the two gears 14, at this time, the two gears 14 and the two compression rollers 13 can rotate in the clockwise direction and the counterclockwise direction under the driving of the driving frame of the driving member.

[0073] Please refer to Figure 9 and Figure 10 When the protrusion 313 is located in the limiting groove 3112a, the extension rod 322 located on the second side in the first horizontal direction enters the specified position, and the extension rod 322 located on the first side does not enter the specified position and is spaced apart from all the protrusions 141. At this time, in the corresponding two gears 14, the gear 14 located on the first side in the second horizontal direction rotates counterclockwise, and the gear 14 located on the second side rotates clockwise, and the two gears 14 push the extension rod 322 and the movable block 321 located on the second side in the first horizontal direction, so that the movable block 321 abuts against the first side wall 3122 of the corresponding sliding groove 3121, so that the extension rod 322 and the movable block 321 cannot continue to move away from the second side wall 3123 of the corresponding sliding groove 3121, so that the extension rod 322 blocks the rotation of the two gears 14.

[0074] Please refer to Figure 11At this time, the gear 14 on the first side rotates clockwise, and the gear 14 on the second side can rotate counterclockwise. The two gears 14 push the extension rod 322 and the movable block 321 on the second side in the first horizontal direction, and the movable block 321 can push the corresponding first elastic member 33 to compress and approach the first side wall 3122 of the corresponding sliding groove 3121, so that the extension rod 322 and the movable block 321 can move close to the second side wall 3123 of the corresponding sliding groove 3121, and the two gears 14 can continue to rotate. In this way, among the corresponding two compression rollers 13, the counterclockwise rotation of the compression roller 13 on the first side in the second horizontal direction and the clockwise rotation of the compression roller 13 on the second side are limited, that is, the two compression rollers 13 cannot drive the clamped sheet material 200 to move in the opposite direction along the first horizontal direction through rotation.

[0075] Please refer to Figure 12 and Figure 13 When the protrusion 313 is located in the limiting groove 3112c, the extension rod 322 on the first side in the first horizontal direction among the two extension rods 322 enters the specified position, and the extension rod 322 on the second side is not located in the specified position and is spaced apart from all the protruding teeth 141. At this time, among the corresponding two gears 14, the gear 14 on the first side in the second horizontal direction rotates clockwise, and the gear 14 on the second side rotates counterclockwise. The two gears 14 push the extension rod 322 and the movable block 321 on the first side in the first horizontal direction, so that the movable block 321 abuts against the first side wall 3122 of the corresponding sliding groove 3121, so that the extension rod 322 and the movable block 321 cannot continue to move away from the second side wall 3123 of the corresponding sliding groove 3121, and the extension rod 322 blocks the rotation of the two gears 14.

[0076] Please refer to Figure 14 At this time, when the gear 14 on the first side rotates counterclockwise and the gear 14 on the second side rotates clockwise, the two gears 14 push the extension rod 322 and the movable block 321 on the first side in the first horizontal direction, and the movable block 321 can push the corresponding first elastic member 33 to compress and approach the first side wall 3122 of the corresponding sliding groove 3121, so that the extension rod 322 and the movable block 321 can move close to the second side wall 3123 of the corresponding sliding groove 3121, and the two gears 14 can continue to rotate. In this way, among the corresponding two compression rollers 13, the clockwise rotation of the compression roller 13 on the first side in the second horizontal direction and the counterclockwise rotation of the compression roller 13 on the second side are limited, that is, the two compression rollers 13 cannot drive the clamped sheet material 200 to move in the positive direction along the first horizontal direction through rotation.

[0077] In the embodiments of the present application, the type of the first elastic member 33 is not specifically limited. For example, the first elastic member 33 can be, but is not limited to, a spring.

[0078] In some embodiments, the limiting seat 31 can further include a handle portion 314. The handle portion 314 is integrally fixed on the moving portion 312 and located on the side of the moving portion 312 away from the gear 14 in the vertical direction. The handle portion 314 can protrude into the receiving groove 3111, and the staff can move the moving portion 312 by holding the handle portion 314.

[0079] In some embodiments, the limiting seat 31 can further include two positioning pins 315. The two positioning pins 315 are respectively located in the two receiving grooves 3111 and are fixedly connected to the moving portion 312. Each positioning pin 315 can pass through the corresponding movable block 321 in the first horizontal direction, so that the movable block 321 is slidingly connected to the positioning pin 315, thereby movably connecting the movable block 321 to the sliding groove 3121.

[0080] It can be understood that the first elastic member 33 can be a spring and can be sleeved on the corresponding positioning pin 315.

[0081] In some embodiments, the clamping device 102 can further include an electrode head 40. Each set of clamping mechanisms 10 can correspond to one electrode head 40. The electrode head 40 can be fixedly connected to one clamping mechanism 10 in each set of clamping mechanisms 10 and fixedly connected to the connecting seat 12 or the fixed seat 11 in the clamping mechanism 10. The electrode head 40 can be electrically connected to the sheet material 200 clamped by the corresponding clamping mechanism 10.

[0082] It can be understood that the film plating process on the sheet material 200 needs to be carried out under the condition that the sheet material 200 is electrified. The electrode head 40 can be electrically connected to an external power supply (not shown) and transmit the current output by the external power supply to the sheet material 200.

[0083] For example, when a plurality of sets of the clamping mechanism 10 are provided in the clamping device 102, the plurality of sets of the clamping mechanism 10 can be arranged in the second horizontal direction with a spacing, each set of the clamping mechanism 10 can clamp one sheet material 200, and the clamping mechanism 10 on the first side in the first horizontal direction of each set of the clamping mechanism 10 can be fixedly connected with one electrode head 40. The electrode heads 40 with the same polarity in the plurality of electrode heads 40 can be connected in parallel, so that the plurality of sheet materials 200 are connected in parallel. The electrode heads 40 corresponding to the adjacent clamping mechanism 10 have different polarities. For example, when the electrode head 40 corresponding to one clamping mechanism 10 is connected with the positive pole of the external power supply, the electrode head 40 corresponding to the adjacent clamping mechanism 10 is connected with the negative pole of the external power supply. In this case, the electrode head 40 connected with the positive pole of the external power supply can be fixedly connected on the connecting seat 12, and the electrode head 40 connected with the negative pole of the external power supply can be fixedly connected on the fixed seat 11; or the electrode head 40 connected with the negative pole of the external power supply can be fixedly connected on the connecting seat 12, and the electrode head 40 connected with the positive pole of the external power supply can be fixedly connected on the fixed seat 11.

[0084] It can be understood that an isolation plate (not shown in the figure) can be arranged between every two adjacent sets of the clamping mechanism 10 and on the clamping mechanism 10 located on the outermost two sides in the plurality of sets of the clamping mechanism 10, so as to block the interference of external electromagnetic signals on the processing of the sheet material 200 after being electrified.

[0085] It can be understood that an isolation plate (not shown in the figure) can be arranged between every two adjacent sets of the clamping mechanism 10 and on the clamping mechanism 10 located on the outermost two sides in the plurality of sets of the clamping mechanism 10, so as to block the interference of external electromagnetic signals on the processing of the sheet material 200 after being electrified. Figure 15 In some embodiments, the clamping device 102 can further include a tensioning mechanism 50. The tensioning mechanism 50 can be fixedly connected to one clamping mechanism 10 in each set of the clamping mechanism 10, that is, the number of the tensioning mechanism 50 is the same as the number of the sets of the clamping mechanism 10. The tensioning mechanism 50 can drive one clamping mechanism 10 in a set of the clamping mechanism 10 to move away from another clamping mechanism 10, so as to enhance the tension of the sheet material 200 clamped by the set of the clamping mechanism 10.

[0086] It can be understood that in each set of the clamping mechanism 10, one clamping mechanism 10 can be fixedly connected to the base 20, and the other clamping mechanism 10 can be movably connected to the base 20 in the first horizontal direction. The tensioning mechanism 50 can be connected to the movable clamping mechanism 10.

[0087] In some embodiments, each tensioning mechanism 50 can include a guide 51 and a second elastic member 52. The second elastic member 52 can drive the clamping mechanism 10 connected to the tensioning mechanism 50 to move in the first horizontal direction by the elastic force of the second elastic member 52.

[0088] The second elastic member 52 can be a spring. The guide member 51 can be in the shape of a rod. The guide member 51 can include a connecting portion 511 and an abutting portion 512, which can be integrally formed. The connecting portion 511 extends in the first horizontal direction, and one end of the connecting portion 511 is fixedly connected to the fixed seat 11 of the corresponding clamping mechanism 10. The abutting portion 512 has a cross-sectional area greater than that of the connecting portion 511. The connecting portion 511 can pass through the base 20 in the first horizontal direction and can be slidably connected to the base 20 in the first horizontal direction. The second elastic member 52 can be sleeved on the connecting portion 511, and one end of the second elastic member 52 can abut against the abutting portion 512, and the other end can abut against the base 20. The abutting portion 512 and the corresponding fixed seat 11 can be located on both sides of the position where the connecting portion 511 passes through the base 20 in the first horizontal direction, respectively.

[0089] The abutting portion 512 can push the second elastic member 52 from one side in the first horizontal direction, and the base 20 can push the second elastic member 52 from the other side in the first horizontal direction, so that the second elastic member 52 is squeezed in the first horizontal direction and elastically deformed; the elastic force generated by the elastic deformation of the second elastic member 52 can drive the abutting portion 512 to move in the first horizontal direction away from the fixed seat 11, so that the connecting portion 511 and the clamping mechanism 10 connected to the connecting portion 511 move synchronously, thereby moving the clamping mechanism 10 away from another clamping mechanism 10 in the same group of clamping mechanisms 10, and realizing tensioning of the sheet-shaped material 200 clamped by the two clamping mechanisms 10.

[0090] The clamping device 102 and the processing equipment 100 provided by the embodiments of the present application can drive the movement of one side of the sheet-shaped material 200 by rotating the two compression rollers 13 in one clamping mechanism 10, so that the sheet-shaped material 200 enters the position between the two compression rollers 13, and the two compression rollers 13 clamp the sheet-shaped material 200. Compared with the scheme of clamping the sheet-shaped material 200 by a plate clamp in the related art, the clamping mechanism 10 provided by the present application can save the process of disassembling and assembling the plate clamp, improve the convenience and efficiency of clamping the sheet-shaped material 200, and thereby improve the efficiency of processing the sheet-shaped material 200.

[0091] Meanwhile, the staff can manually adjust the position of the moving part 312 in the limiting mechanism 30 according to the position (e.g. the first side or the second side) of the corresponding clamping mechanism 10 in the first horizontal direction, so that one of the extension rods 322 in the corresponding blocking piece 32 enters the designated position, so that the corresponding two gears 14 can only rotate in the defined circumferential direction, and then the corresponding two compression rollers 13 can only rotate in the defined direction, so that one side of the sheet-shaped material 200 clamped by the two compression rollers 13 can only move in the defined straight line direction (e.g. the positive direction or the reverse direction of the first horizontal direction). In this way, the first side of the sheet-shaped material 200 in the first horizontal direction can only move in the reverse direction of the first horizontal direction, and the second side can only move in the positive direction of the first horizontal direction, so that the rotation of the compression roller 13 can clamp and tension the sheet-shaped material 200, and the sheet-shaped material 200 cannot be loosened from the compression roller 13. The tensioning mechanism 50 can drive one clamping mechanism 10 away from another clamping mechanism 10 in a group of clamping mechanisms 10, thereby enhancing the tensioning of the sheet-shaped material 200. It can reduce the situation that the sheet-shaped material 200 falls off the compression roller 13 or wrinkles or deforms during processing, and can improve the processing effect of the sheet-shaped material 200 and improve the yield of the processed sheet-shaped material 200.

[0092] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the above-described embodiments of the present application should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
