DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

In addition, it should be understood that in the description of the present application, the terms "first", "second", and the like are used only for the purpose of distinguishing the described purposes, and cannot be understood as indicating or implying relative importance, nor can it be understood as indicating or implying order.

[0027] In the description of the embodiments of the present application, the terms "exemplary" or "for example" are used to represent 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 terms "exemplary" or "for example" are used to present the relevant concept in a specific manner.

[0028] Please refer to Figure 1 , Figure 1 An embodiment of the present application provides a processing equipment 100. The processing equipment 100 can accommodate a plurality of sheet materials 200 and perform plating processing on the plurality of sheet materials 200.

[0029] In the embodiments 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.

[0030] In the embodiments 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, both sides of the sheet material 200 can form a silicon-containing layer. The material of the silicon-containing layer includes silicon and / or a silicon-containing compound, and 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.

[0031] In an embodiment, the processing equipment 100 can include a reaction furnace 101 and a clamping device 102. The clamping device 102 can clamp a plurality of sheet materials 200 and keep the sheet materials 200 in a tensioned state. The clamping device 102 can be received on a carrier (not shown) or hung on a hoisting frame (not shown), and then moved into or out of the reaction furnace synchronously with the carrier or the hoisting frame. The reaction furnace 101 can be supplied with a reaction gas, and the sheet material 200 located in the reaction furnace 101 can be heated, so that the sheet material 200 reacts with the reaction gas after plating to complete the plating.

[0032] Please refer to Figure 2 , Figure 2A clamping device 102 provided by an embodiment of the present application is shown. In an embodiment of the present application, a length direction of the processing equipment 100 and the clamping device 102 is defined as a first horizontal direction, a width direction is defined as a second horizontal direction, and a height direction is defined as a vertical direction. For example, the first horizontal direction can be an X direction in Figure 1 and Figure 2 , the second horizontal direction can be a Y direction in Figure 2 , and the vertical direction can be a Z direction in Figure 1 and Figure 2 .

[0033] In an embodiment of the present application, the principle of the processing equipment 100 processing the sheet 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 material 200 according to the principle of plasma enhanced chemical vapor deposition (PECVD).

[0034] It can be understood that the clamping device 102 can be fixedly installed on a carrier or a hoisting frame, or can be separably installed on the carrier or the hoisting frame, and an embodiment of the present application does not limit this.

[0035] In an embodiment 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 molding fixing, etc.

[0036] In an embodiment of the present application, the connection manner of separable connection is not specifically limited. For example, the connection manner of separable connection can be, but is not limited to, threaded connection, screw connection, bolt connection, buckle connection, etc.

[0037] Referring to Figure 3 and Figure 4 together, the clamping device 102 can include a clamping mechanism 10. The number of the clamping mechanism 10 can be one or more groups, and the number of the clamping mechanism 10 in each group of the clamping mechanism 10 is two.

[0038] In each group of the clamping mechanism 10, the two clamping mechanisms 10 are spaced apart and symmetrically arranged in the first horizontal direction. The two clamping mechanisms 10 can respectively clamp two ends of the same sheet material 200 in the first horizontal direction, thereby achieving clamping and fixing of one sheet material 200. Each group of the clamping mechanism 10 can be arranged on a carrier or a hoisting frame. In this way, the relative fixing of the sheet material 200 clamped by each group of the clamping mechanism 10 and the carrier or the hoisting frame can be achieved.

[0039] It can be understood that the clamping device 102 can keep the sheet material 200 relatively fixed with the carrier or the hoisting frame, i.e., the sheet material 200 can be kept stationary in the reaction furnace 101, the movement of the sheet material 200 in the reaction furnace 101 during processing can be reduced, and the situation that the sheet material 200 is not processed well due to movement can be reduced.

[0040] It can be understood that when the clamping mechanism 10 is provided in multiple groups, the multiple groups of clamping mechanisms 10 can be arranged in the second horizontal direction. Each group of clamping mechanisms 10 can clamp one sheet material 200, so that the clamping device 102 can clamp multiple sheet materials 200, and when the clamping device 102 enters the reaction furnace 101 synchronously with the multiple sheet materials 200, the processing equipment 100 can process the multiple sheet materials 200 synchronously.

[0041] Please refer to Figure 5 and Figure 6 In some embodiments, each clamping mechanism 10 can include a fixed frame 11 and a wheel pressing assembly 12. The fixed frame 11 can be provided on the carrier or the hoisting frame. In each group of clamping mechanisms 10, the fixed frame 11 is provided with a wheel pressing assembly 12 on one side thereof in the first horizontal direction. In each clamping mechanism 10, the wheel pressing assembly 12 can cooperate with the wheel pressing assembly 12 adjacent in the second horizontal direction to clamp the sheet material 200, or can cooperate with the fixed frame 11 to clamp the sheet material 200.

[0042] It can be understood that the number of fixed frames 11 in each clamping mechanism 10 is one. In the embodiments of the present application, the number of wheel pressing assemblies 12 in each clamping mechanism 10 is not specifically limited. For example, each clamping mechanism 10 can include a row of wheel pressing assemblies 12, the number of wheel pressing assemblies 12 in the row of wheel pressing assemblies 12 is multiple, and the multiple wheel pressing assemblies 12 are arranged in the vertical direction; each wheel pressing assembly 12 can cooperate with the fixed frame 11 to clamp the metal foil. For another example, as shown in Figure 5 and Figure 6 Each clamping mechanism 10 can include two rows of wheel pressing assemblies 12, the two rows of wheel pressing assemblies 12 are arranged in the second horizontal direction, the number of wheel pressing assemblies 12 in each row of wheel pressing assemblies 12 is multiple, and the multiple wheel pressing assemblies 12 are arranged in the vertical direction; the two rows of wheel pressing assemblies 12 correspond to each other, and each wheel pressing assembly 12 can cooperate with the corresponding wheel pressing assembly 12 in the other row of wheel pressing assemblies 12 to clamp the metal foil.

[0043] The following embodiments are exemplified according to the case that two rows of wheel pressing assemblies 12 are provided on each fixed frame 11.

[0044] In some embodiments, the fixing frame 11 can include a fixing member 111 and a clamping head 112. The fixing member 111 can be arranged on a bearing frame or a hoisting frame. The number of the clamping head 112 can be multiple, and the multiple clamping heads 112 are arranged in the vertical direction. The multiple clamping heads 112 are protruded from the corresponding fixing member 111 towards the side of the other fixing frame 11 in the same group of clamping mechanisms 10, and are integrally formed with the corresponding fixing member 111. Each clamping head 112 is provided with a positioning groove 113 towards the side of the other fixing frame 11 in the same group of clamping mechanisms 10. The positioning groove 113 penetrates the clamping head 112 in the vertical direction. The width of the positioning groove 113 in the second horizontal direction is greater than the thickness of the sheet material 200 in the second horizontal direction. The positioning groove 113 can accommodate one end of the sheet material 200 in the first horizontal direction.

[0045] Each clamping head 112 includes two clamping portions 1121, and the two clamping portions 1121 are arranged in the second horizontal direction and located on both sides of the positioning groove 113. The side of each clamping head 112 provided with the positioning groove 113 is also provided with two accommodation grooves 114, and the two accommodation grooves 114 are respectively located on the two clamping portions 1121 and communicate with the positioning groove 113. Each accommodation groove 114 can at least partially accommodate one wheel pressing assembly 12.

[0046] Each wheel pressing assembly 12 can be connected to the corresponding clamping portion 1121. Each wheel pressing assembly 12 can include a pressing wheel 121, a clamping driving member 122 and a limiting rod 123. Each pressing wheel 121 is arranged in the corresponding accommodation groove 114 and is rotatably connected to the corresponding clamping portion 1121. The axial direction of the pressing wheel 121 coincides with the vertical direction. The central axis of the pressing wheel 121 is parallel to the rotation center axis of the pressing wheel 121, that is, the pressing wheel 121 can perform eccentric rotation. When the pressing wheel 121 rotates, it can pass through the accommodation groove 114 and at least partially enter the positioning groove 113, and the arc wall of the pressing wheel 121 can abut against the sheet material 200. When two adjacent pressing wheels 121 in the second horizontal direction jointly enter the same positioning groove 113, they can abut against the two sides of the sheet material 200 in the second horizontal direction, respectively, to clamp the sheet material 200.

[0047] The clamping driving member 122 can be an elastic member, and the clamping driving member 122 is accommodated in the corresponding accommodation groove 114. The clamping driving member 122 can be fixedly connected to the corresponding pressing wheel 121 and the inner wall of the corresponding accommodation groove 114. The clamping driving member 122 can drive the corresponding pressing wheel 121 to rotate by the elastic force generated by the elastic deformation of the clamping driving member 122, so that the pressing wheel 121 enters the positioning groove 113.

[0048] The pressing wheel 121 can be provided with a limiting slot 124 extending through the pressing wheel 121 in the vertical direction and extending along the rotating direction of the pressing wheel 121. The limiting rod 123 extends in the vertical direction and is fixedly connected to the corresponding fixed part 1121. Part of the limiting rod 123 is arranged in the accommodating slot 114 and extends through the limiting slot 124 of the corresponding pressing wheel 121. When the pressing wheel 121 rotates, the pressing wheel 121 and the limiting rod 123 are relatively displaced, and the limiting rod 123 can be relatively displaced in the limiting slot 124. The limiting rod 123 can abut against both ends of the inner wall of the limiting slot 124, so as to limit the rotating angle of the pressing wheel 121.

[0049] In the embodiments of the present application, the type and number of the clamping driving members 122 are not limited. For example, the clamping driving member 122 can be a torsion spring. In each wheel pressing assembly 12, the number of the clamping driving members 122 can be two, and the two clamping driving members 122 are arranged in the same accommodating slot 114 and are spaced apart in the vertical direction. The two clamping driving members 122 are arranged on the two sides of the corresponding pressing wheel 121 in the vertical direction and are fixedly connected to the pressing wheel 121. The two clamping driving members 122 are fixedly connected to the top wall and the bottom wall of the corresponding accommodating slot 114 in the vertical direction.

[0050] Please refer to Figure 7 and Figure 8 It can be understood that each clamping driving member 122 is used to drive the corresponding pressing wheel 121 to rotate from the accommodating slot 114 and at least partially enter the positioning slot 113. The part of each pressing wheel 121 used to enter the positioning slot 113 can be defined as a clamping part, and the clamping part is spaced apart from the rotating center axis of the pressing wheel 121. Two wheel pressing assemblies 12 arranged at the same height in the vertical direction can be defined as two corresponding wheel pressing assemblies 12. In the two corresponding wheel pressing assemblies 12, each clamping driving member 122 can drive the corresponding clamping part to approach the clamping part on the other pressing wheel 121, that is, the clamping driving members 122 in the two pressing wheel 121 assemblies can drive the clamping parts of the two pressing wheels 121 to approach each other and can generate a pre-tightening force between the two pressing wheels 121. The two clamping parts can approach each other and enter the positioning slot 113 to clamp the sheet material 200.

[0051] When it is needed to clamp the sheet material 200 by the clamping device 102, the worker or the automatic equipment can grab the sheet material 200, move the sheet material 200 to one side of the clamping mechanism 10 in the first horizontal direction, and align the sheet material 200 with the positioning groove 113, and then move the sheet material 200 in the first horizontal direction to insert one end of the sheet material 200 into the positioning groove 113; when the sheet material 200 is inserted into the positioning groove 113, the sheet material 200 abuts against the pressing wheels 121 of the two rows of wheel pressing assemblies 12, and pushes the pressing wheels 121 to rotate, so that the pressing wheels 121 rotate in a direction away from the other pressing wheel 121 arranged correspondingly and partially move out of the positioning groove 113; the two rows of pressing wheels 121 can keep abutting against the two sides of the sheet material 200 under the driving of the clamping driving member 122, so as to clamp the sheet material 200 after the sheet material 200 enters the positioning groove 113. Then, the worker or the automatic equipment can reversely move the sheet material 200 to insert the other end of the sheet material 200 into the positioning groove 113 in the other clamping mechanism 10; or the worker or the automatic equipment can move the other clamping mechanism 10 in the same group of clamping mechanisms 10 to make the other clamping mechanism 10 close to the other end of the sheet material 200, and make the other end of the sheet material 200 enter the positioning groove 113. In this way, the clamping of one sheet material 200 by one group of clamping mechanisms 10 can be realized.

[0052] The clamping of the sheet material 200 by the clamping device 102 can be realized by the relative movement of the sheet material 200 and the clamping mechanism 10 in the first horizontal direction, which can simplify the process of clamping the sheet material 200, for example, the process of rotating the bolt or pressing the buckle to clamp the sheet material 200 by the plate clamp can be saved; and the processing efficiency of the sheet material 200 can be improved.

[0053] In the embodiments of the present application, the material of the pressing wheel 121 is not specifically limited. For example, the pressing wheel 121 can be a hard metal material, and the arc wall of the pressing wheel 121 can be provided with anti-slip lines. For another example, the pressing wheel 121 can be a material with elasticity such as silica gel or rubber.

[0054] It can be understood that the rotatable connection can be realized by a rotating connecting member, and the rotating connecting member can be a connecting mode in which the relative rotation of two components can be realized. In the embodiments of the present application, the type of the rotating connecting member is not specifically limited. For example, the rotating connecting member can be, but is not limited to, a pin shaft, a bearing, a hinge, etc.

[0055] Exemplarily, each clamping mechanism 10 may further include a pin 125. The pin 125 extends in the vertical direction. The pin 125 may pass through the corresponding fixing portion 1121 and be fixedly connected to the fixing portion 1121. Part of the structure of the pin 125 enters the receiving groove 114. The pin 125 may pass through the pressure wheel 121 in the receiving groove 114, and the pressure wheel 121 and the pin 125 rotate together to achieve a rotatable connection between the pressure wheel 121 and the fixing portion 1121. The central axis of the pin 125 is parallel to the central axis of the pressure wheel 121.

[0056] In other embodiments, when a row of wheel pressing assemblies 12 are provided on each fixing frame 11, a fixing portion 1121 on each clamping head 112 may have a receiving groove 114, while the other fixing portion 1121 does not have a receiving groove 114, thereby closing the side of the positioning groove 113 away from the receiving groove 114; the pressing wheel 121 may pass through the receiving groove 114 and at least partially enter the positioning groove 113, and cooperate with the fixing portion 1121 that does not have a receiving groove 114 to clamp the sheet material 200.

[0057] In some embodiments, the clamping device 102 may further include an electrode head 20. The number of electrode heads 20 may be equal to the number of groups of clamping mechanisms 10, i.e., each group of clamping mechanisms 10 may be provided with an electrode head 20. The electrode head 20 may be fixedly connected to one clamping mechanism 10 in each group of clamping mechanisms 10 and fixedly connected to the fixing frame 11 in the clamping mechanism 10. The electrode head 20 may be electrically connected to the sheet material 200 clamped by the corresponding clamping mechanism 10.

[0058] It is understood that the coating process on the sheet material 200 needs to be performed under the condition that the sheet material 200 is powered. The electrode head 20 can be electrically connected to an external power source (not shown) and transmit the current output by the external power source to the sheet material 200.

[0059] For example, when multiple groups of clamping mechanisms 10 are provided in the clamping device 102, the multiple groups of clamping mechanisms 10 can be spaced apart in the second horizontal direction, and each group of clamping mechanisms 10 can clamp one sheet material 200. The clamping mechanisms 10 located on the first side of each group of clamping mechanisms 10 in the first horizontal direction can be fixedly mounted with one electrode head 20. The multiple electrode heads 20 can be connected in parallel, thereby connecting multiple sheet materials 200 in parallel, and the polarity of the electrode heads 20 corresponding to adjacent clamping mechanisms 10 is different. For example, when the electrode head 20 corresponding to one clamping mechanism 10 is connected to the positive pole of an external power supply, the electrode head 20 corresponding to an adjacent clamping mechanism 10 is connected to the negative pole of the external power supply.

[0060] Among them, Figure 4 As shown, the first side in the first horizontal direction may be the side facing away from by the X-direction arrow.

[0061] In some embodiments, the clamping device 102 can further comprise isolation plates 30. Each clamping mechanism 10 is provided with an isolation plate 30 on both sides in the second horizontal direction. The isolation plate 30 can be fixedly connected with the corresponding fixing member 111. The isolation plate 30 can block the electromagnetic interference from the outside to the sheet material 200, thereby improving the processing effect of the sheet material 200.

[0062] In the embodiments of the present application, the material of the isolation plate 30 is not specifically limited. For example, the material of the isolation plate 30 can be, but is not limited to, ceramic.

[0063] It can be understood that when the clamping mechanisms 10 in the clamping device 102 are provided in multiple groups, an isolation plate 30 is provided between the clamping mechanisms 10 adjacent in the second horizontal direction; among the multiple clamping mechanisms 10 on the same side in the first horizontal direction, the two clamping mechanisms 10 on the outermost side in the second horizontal direction are provided with an isolation plate 30 on the side away from each other. The number of isolation plates 30 can be two more than the number of clamping mechanisms 10.

[0064] In some embodiments, in a group of clamping mechanisms 10, one clamping mechanism 10 can be fixedly connected with the carrier or the hoisting frame, and the other clamping mechanism 10 can be movably connected with the carrier or the hoisting frame in the first horizontal direction. The clamping device 102 can further comprise vertical plates 40 and tensioning mechanisms 50. The number of vertical plates 40 and tensioning mechanisms 50 is equal to the number of groups of clamping mechanisms 10 in the clamping device 102. The multiple groups of clamping mechanisms 10, the multiple vertical plates 40 and the multiple tensioning mechanisms 50 correspond one by one.

[0065] The vertical plate 40 can be fixedly installed on the carrier or the hoisting frame and located on the side of the corresponding group of clamping mechanisms 10 in the first horizontal direction and adjacent to the movable clamping mechanism 10. The tensioning mechanism 50 is connected with the corresponding vertical plate 40 and the clamping mechanism 10 adjacent to the vertical plate 40 in the first horizontal direction. The tensioning mechanism 50 can drive the connected clamping mechanism 10 to move away from the other clamping mechanism 10 in the same group of clamping mechanisms 10 in the first horizontal direction, thereby realizing the tensioning of the sheet material 200 clamped by the clamping mechanism 10 by increasing the distance between the two clamping mechanisms 10.

[0066] It can be understood that the coating processing of the sheet material 200 needs to be carried out in a high-temperature environment (for example, 500-600 degrees Celsius). The increase of temperature will cause the sheet material 200 to be extended, so that the length of the sheet material 200 in the first horizontal direction increases. The tensioning mechanism 50 can cooperate with the clamping mechanism 10 to realize the tensioning of the sheet material 200, thereby reducing the wrinkles or deformation of the sheet material 200 during processing. 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.

[0067] In some embodiments, the tensioning mechanism 50 can include a guide 51 and a tensioning driving member 52. The tensioning driving member 52 can be an elastic member. The driving member can be driven to move the clamping mechanism 10 in the first horizontal direction by the elastic force of the tensioning driving member 52.

[0068] The tensioning driving member 52 can be a spring. The guide 51 can be in the shape of a rod. The number of the guides 51 and the number of the tensioning driving members 52 in each tensioning mechanism can be one or more. The number of the tensioning driving members 52 can be equal to the number of the guides 51, and the plurality of tensioning driving members 52 can correspond to the plurality of guides 51 one by one. The guide 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 corresponding fixed member 111, and the other end is fixedly connected to the abutting portion 512. The cross-sectional area of the abutting portion 512 is greater than that of the connecting portion 511. The connecting portion 511 can pass through the corresponding vertical plate 40 in the first horizontal direction, and can be slidably connected to the vertical plate 40 in the first horizontal direction. The tensioning driving member 52 can be sleeved on the connecting portion 511, and one end of the tensioning driving member 52 can abut against the abutting portion 512, and the other end can abut against the vertical plate 40. The abutting portion 512 and the corresponding fixed member 111 can be located on the two sides of the vertical plate 40 in the first horizontal direction, respectively.

[0069] The abutting portion 512 can push the tensioning driving member 52 from one side in the first horizontal direction, and the vertical plate 40 can push the tensioning driving member 52 from the other side in the first horizontal direction, so that the tensioning driving member 52 is extruded in the first horizontal direction and elastically deformed. The elastic force generated by the elastic deformation of the tensioning driving member 52 can drive the abutting portion 512 to move in the first horizontal direction away from the fixed member 111 and the vertical plate 40, 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 the tensioning of the sheet-shaped material 200 clamped by the two clamping mechanisms 10.

[0070] In the embodiments of the present application, the number of the guides 51 and the number of the tensioning driving members 52 are not specifically limited. For example, the number of the guides 51 and the number of the tensioning driving members 52 can be multiple, the plurality of guides 51 are arranged at intervals in the vertical direction, the plurality of tensioning driving members 52 are arranged at intervals in the vertical direction, and the plurality of guides 51 correspond to the plurality of tensioning driving members 52 one by one.

[0071] In other embodiments, two clamping mechanisms 10 in each set of clamping mechanisms 10 can be movably connected to the frame in the first horizontal direction, and each of the two clamping mechanisms 10 is provided with a vertical plate 40 on the side away from the other clamping mechanism 10, and each of the two clamping mechanisms 10 is connected to the tensioning mechanism 50. The two clamping mechanisms 10 can move away from each other to achieve tensioning of the clamped sheet material 200.

[0072] It can be understood that when one clamping mechanism 10 in each set of clamping mechanisms 10 is not movable and the other clamping mechanism 10 is movable, the electrode head 20 can be fixedly installed on the fixed part 111 in the non-movable clamping mechanism 10; when both clamping mechanisms 10 in each set of clamping mechanisms 10 are movable, the electrode head 20 can be fixedly installed on any fixed part 111.

[0073] For example, in each set of clamping mechanisms 10, the clamping mechanism 10 on the first side in the first horizontal direction is fixedly connected to the carrier or hoisting frame and fixedly connected to the electrode head 20; the clamping mechanism 10 on the second side in the first horizontal direction is movably connected to the carrier or hoisting frame in the first horizontal direction and fixedly connected to the connecting part 511.

[0074] In some embodiments, the clamping device 102 can further include two outer electrode plates 60. When the clamping device 102 includes multiple sets of clamping mechanisms 10 and the multiple sets of clamping mechanisms 10 are arranged in the second horizontal direction, the two outer electrode plates 60 are respectively located on the two sides of the multiple sets of clamping mechanisms 10 in the second horizontal direction, and the two outer electrode plates 60 can be respectively fixedly connected to the isolation plates 30 on the two outermost sets of clamping mechanisms 10 in the multiple sets of clamping mechanisms 10.

[0075] The two outer electrode plates 60 can be respectively electrically connected to the positive and negative poles of an external power source, and the outer electrode plate 60 electrically connected to the positive pole can be connected in parallel with the multiple electrode heads 20 connected to the positive pole of the external power source, and the outer electrode plate 60 electrically connected to the negative pole can be connected in parallel with the multiple electrode heads 20 connected to the negative pole of the external power source. In this way, after the electrode heads 20 and the outer electrode plates 60 are powered on, the two surfaces of the sheet material 200 clamped by each set of clamping mechanisms 10 can be subjected to film plating processing.

[0076] It can be understood that when the clamping device 102 provided by the embodiment of the present application clamps the sheet material 200, the worker or the automatic equipment can grab the sheet material 200, move the sheet material 200 to one side of the immovable clamping mechanism 10 in the first horizontal direction, and align the sheet material 200 with the positioning groove 113, and then move the sheet material 200 in the first horizontal direction to insert one end of the sheet material 200 into the positioning groove 113; when the sheet material 200 is inserted into the positioning groove 113, the sheet material 200 abuts against the pressing wheels 121 of the two rows of wheel pressing assemblies 12, and pushes the pressing wheels 121 to rotate, so that the pressing wheels 121 rotate away from the other pressing wheels 121 arranged correspondingly and partially move out of the positioning groove 113; the two rows of pressing wheels 121 can keep abutting against the two sides of the sheet material 200 under the driving of the clamping driving member 122, so as to clamp the sheet material 200 after the sheet material 200 enters the positioning groove 113. Then, the worker or the automatic equipment can move another clamping mechanism 10 in the same group of clamping mechanisms 10 to make the other clamping mechanism 10 close to the other end of the sheet material 200, and make the other end of the sheet material 200 enter the positioning groove 113; in this process, the tensioning driving member 52 in the tensioning mechanism 50 is elastically deformed due to compression; when both clamping mechanisms 10 complete clamping of the sheet material 200, the tensioning driving member 52 can drive the connected clamping mechanism 10 to move away from the other clamping mechanism 10 in the same group of clamping mechanisms 10, so as to realize tensioning of the sheet material 200.

[0077] Through the clamping device 102 and the processing equipment 100 provided by the embodiment of the present application, after the relative movement of the sheet material 200 and the clamping mechanism 10 in the first horizontal direction, the sheet material 200 can enter the corresponding positioning groove 113 and abut against the corresponding pressing wheel 121, and the clamping mechanism 10 can clamp the sheet material 200, so as to simplify the process of clamping the sheet material 200 and improve the processing efficiency of the sheet material 200. Meanwhile, when a group of clamping mechanisms 10 complete clamping of both ends of the sheet material 200, the tensioning driving member 52 can drive one of the clamping mechanisms 10 to move away from the other clamping mechanism 10, so as to realize tensioning of the sheet material 200 by increasing the distance between the two clamping mechanisms 10, which can improve the processing effect of the sheet material 200 and improve the yield of the processed sheet material 200.

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 range of equivalents of the elements of the claims are intended to be embraced in the present application.
