DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments of the present application.

[0028] In the present application, a plurality refers to two or more. In addition, it should be understood that in the description of the present application, the words "first", "second", etc. are used only for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance or indicating or implying order.

[0029] In the description of the embodiments of the present application, the words "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of the words "exemplary" or "for example" is intended to present the relevant concept in a specific manner.

[0030] Please refer to Figure 1 , Figure 1 A processing device 100 provided by an embodiment of the present application is shown. The processing device 100 can accommodate a plurality of sheet materials 200 and perform film plating processing on the plurality of sheet materials 200.

[0031] 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.

[0032] In the embodiments of the present application, the material of the film formed after the sheet material 200 is plated is not specifically limited. For example, after the sheet material 200 is plated, silicon-containing layers 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.

[0033] In an embodiment, the processing apparatus 100 can include a reaction furnace 101 and a tensioning device 102. The tensioning device 102 can hold a plurality of sheet materials 200 and keep the sheet materials 200 in a tensioned state. The reaction furnace 101 can accommodate the tensioning device 102. The reaction furnace 101 can receive a reaction gas and heat the sheet materials 200 located in the reaction furnace 101, so that the sheet materials 200 are reacted with the reaction gas to complete film coating.

[0034] In an embodiment of the present application, a length direction of the processing apparatus 100 and the tensioning device 102 can be defined as a first horizontal direction, a width direction can be defined as a second horizontal direction, and a height direction can be defined as a vertical direction. For example, as shown in FIG. 1, the first horizontal direction can be an X direction, the second horizontal direction can be a Y direction, and the vertical direction can be a Z direction. Figure 1

[0035] In an embodiment of the present application, the principle of the processing apparatus 100 processing the sheet materials 200 through the reaction furnace 101 is not specifically limited. For example, the processing apparatus 100 can perform film coating processing on the sheet materials 200 according to the principle of plasma enhanced chemical vapor deposition (PECVD).

[0036] Referring to FIG. 2, the tensioning device 102 can include a carrier 10, a clamping mechanism 20, an electrode head 30, and a tensioning mechanism 40. Figure 2

[0037] The carrier 10 can include a bottom plate 11 and two side plates 12. The bottom plate 11 extends along the first horizontal direction. The two side plates 12 are fixedly installed on the bottom plate 11, and both extend along the vertical direction and are spaced apart in the first horizontal direction.

[0038] The clamping mechanism 20 is disposed on the bottom plate 11 and located between the two side plates 12. The clamping mechanism 20 can clamp both ends of the sheet materials 200 in the first horizontal direction. The electrode head 30 can be fixedly installed on the clamping mechanism 20 and electrically connected to the sheet materials 200 clamped by the clamping mechanism 20. The tensioning mechanism 40 is connected to the clamping mechanism 20 and used to drive at least part of the structure of the clamping mechanism 20 to move in the first horizontal direction, so that at least one end of the sheet materials 200 moves away from the other end, thereby achieving tensioning of the sheet materials 200.

[0039] It can be understood that film coating processing on the sheet materials 200 needs to be performed under the condition that the sheet materials 200 are powered on. The electrode head 30 can be electrically connected to an external power supply (not shown) and transmit the current output by the external power supply to the sheet materials 200. ​​

[0040] 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 be ductile, increasing the length of the sheet material 200 in the first horizontal direction. The tensioning mechanism 40 can cooperate with the clamping mechanism 20 to achieve tensioning of the sheet material 200, reducing the occurrence of 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 sheet material 200 after processing can be improved.

[0041] In the embodiments of the present application, the fixing mode when fixedly connected and fixedly installed is not specifically limited. For example, the fixing mode can be, but is not limited to, welding fixation, screw fixation, bolt fixation, buckle fixation, integral molding fixation, etc.

[0042] It can be understood that each clamping mechanism 20 can correspondingly be provided with at least one tensioning mechanism 40 and an electrode head 30. In the embodiments of the present application, the number of clamping mechanisms 20, tensioning mechanisms 40 and electrode heads 30 is not specifically limited. For example, the number of clamping mechanisms 20 can be multiple, and multiple clamping mechanisms 20 can be spaced apart in the second horizontal direction. Each clamping mechanism 20 can clamp one sheet material 200, and each clamping mechanism 20 can realize tensioning of the sheet material 200 through the corresponding at least one tensioning mechanism 40. Each clamping mechanism 20 is correspondingly provided with one electrode head 30, and multiple electrode heads 30 can be connected in parallel, so that multiple sheet materials 200 are connected in parallel, and the polarities of the electrode heads 30 corresponding to adjacent clamping mechanisms 20 are different. For example, when the electrode head 30 corresponding to one clamping mechanism 20 is connected to the positive electrode of an external power supply, the electrode head 30 corresponding to an adjacent clamping mechanism 20 is connected to the negative electrode of the external power supply.

[0043] In some embodiments, each clamping mechanism 20 can include two clamping assemblies. The two clamping assemblies can be spaced apart in the first horizontal direction. The two clamping assemblies can clamp two ends of one sheet material 200 in the first horizontal direction, respectively. The two clamping assemblies are correspondingly provided with two side plates 12, respectively. At least one clamping assembly is movably arranged on the bottom plate 11 in the first horizontal direction and movably connected to the corresponding side plate 12.

[0044] In the embodiments of the present application, the number of clamping assemblies movably arranged on the base plate 11 in each clamping mechanism 20 is not specifically limited. For example, in each clamping mechanism 20, one of the two clamping assemblies is fixedly connected with the corresponding side plate 12 to be relatively fixedly arranged on the base plate 11, and the other clamping assembly is movably connected with the corresponding side plate 12 in the first horizontal direction to be movably arranged on the base plate 11, and the movable clamping assembly can be moved away from the other clamping assembly to stretch the sheet material 200. For another example, in each clamping mechanism 20, both of the two clamping assemblies are movably connected with the corresponding side plate 12 in the first horizontal direction, and the two clamping assemblies can be respectively arranged with a tensioning mechanism 40 and can be moved away from each other to stretch the sheet material 200.

[0045] It can be understood that the electrode head 30 can be fixedly connected with one or both of the clamping assemblies in the clamping mechanism 20, and the embodiments of the present application are not limited in this regard. For example, when in each clamping mechanism 20, one of the two clamping assemblies is fixed with the corresponding side plate 12, and the other clamping assembly is movably connected with the corresponding side plate 12, the electrode head 30 is fixedly connected with the side of the clamping assembly fixed with the corresponding side plate 12.

[0046] Please refer to Figure 3 and Figure 4 In some embodiments, each clamping assembly can include a first clamping plate 21, a second clamping plate 22, and a clamping piece 23. The first clamping plate 21 and the second clamping plate 22 can be arranged in the second horizontal direction, and the side of the first clamping plate 21 facing the second clamping plate 22 is provided with a clamping groove 211. The clamping groove 211 can accommodate one end of the sheet material 200, and the clamping groove 211 can at least partially accommodate the second clamping plate 22. The first clamping plate 21 can be separably connected with the second clamping plate 22 entering the clamping groove 211. The second clamping plate 22 can abut against one side of the part of the sheet material 200 entering the clamping groove 211 in the second horizontal direction, and the side wall of the clamping groove 211 can abut against the other side of the part of the sheet material 200 entering the clamping groove 211 in the second horizontal direction, so that the first clamping plate 21 and the second clamping plate 22 can clamp one end of the sheet material 200 in the second horizontal direction.

[0047] The first clamping plate 21 and the second clamping plate 22 are provided with clamping grooves 24 on the surfaces facing away from each other in the second horizontal direction. The clamping grooves 24 extend through the first clamping plate 21 and the second clamping plate 22 in the vertical direction. The clamping member 23 is provided with a receiving groove 231 on one side in the first horizontal direction, and the receiving groove 231 extends through the clamping member 23 in the vertical direction. The receiving groove 231 can accommodate the first clamping plate 21 and the second clamping plate 22, and the two side walls of the receiving groove 231 in the second horizontal direction can limit the movement of the first clamping plate 21 and the second clamping plate 22 in the second horizontal direction. The two side walls of the receiving groove 231 facing each other in the second horizontal direction can be provided with protrusions 232. The protrusions 232 can be integrally formed on the inner wall of the receiving groove 231. The two protrusions 232 can be respectively embedded in the clamping grooves 24 provided on the first clamping plate 21 and the second clamping plate 22, so as to limit the movement of the first clamping plate 21 and the second clamping plate 22 in the first horizontal direction. In this way, the clamping member 23 can clampingly fix the first clamping plate 21 and the second clamping plate 22 which have clamped the sheet material 200.

[0048] In the embodiments of the present application, the corresponding connection mode for separable connection is not specifically limited. For example, the connection mode for separable connection can include, but is not limited to, screw connection, bolt connection, buckle connection, adhesive connection, etc. For example, the first clamping plate 21 and the second clamping plate 22 can be separably connected by screws.

[0049] It can be understood that the clamping mechanism 20 for fixed connection with the electrode head 30 can be fixedly connected with the electrode head 30 through the clamping member 23.

[0050] It can be understood that the clamping groove 211 can extend through the first clamping plate 21 in the first horizontal direction. The surface of the first clamping plate 21 provided with the clamping groove 211 in the second horizontal direction can be parallel to the surface of the second clamping plate 22 facing away from the first clamping plate 21 in the second horizontal direction. The surface of the first clamping plate 21 provided with the clamping groove 211 can be provided with the clamping groove 24, and when the first clamping plate 21 and the second clamping plate 22 clamp the sheet material 22, the clamping groove 24 on the surface of the first clamping plate 21 provided with the clamping groove 211 can be communicated with the clamping groove 24 on the second clamping plate 22. One of the protrusions 232 on the clamping member 23 can be simultaneously embedded in the clamping groove on the second clamping plate 22 and the clamping groove 24 on the surface of the first clamping plate 21 provided with the clamping groove 211, so as to strengthen the limitation of the movement of the first clamping plate 21 and the second clamping plate 22.

[0051] Please refer to Figure 5 In some embodiments, the tensioning device 102 can further include isolation plates 50. Each clamping assembly is provided with an isolation plate 50 on each side in the second horizontal direction. The isolation plate 50 can be fixedly connected with the corresponding clamping member 23. The isolation plate 50 can block the electromagnetic interference from the outside to the sheet material 200, so as to improve the processing effect of the sheet material 200.

[0052] In the embodiments of the present application, the material of the isolation plate 50 is not particularly limited. For example, the material of the isolation plate 50 can be, but is not limited to, ceramic.

[0053] It can be understood that when the tensioning device 102 includes a plurality of clamping mechanisms 20, an isolation plate 50 is arranged between adjacent clamping mechanisms 20, and two clamping mechanisms 20 located at the outermost sides in the second horizontal direction in the plurality of clamping mechanisms 20 are respectively arranged with an isolation plate 50 on the side away from each other. The number of isolation plates 50 can be one more than the number of clamping mechanisms 20.

[0054] Please refer to Figure 6 and Figure 7 In some embodiments, the tensioning mechanism 40 can include a guide 41 and a drive 42. The guide 41 can be fixedly connected to the clamping assembly movable in the first horizontal direction, and the guide 41 can be fixedly connected with the clamping member 23 in the clamping assembly. The guide 41 can be located on the side of the corresponding clamping member 23 facing the corresponding side plate 12. The guide 41 can be movably connected to the corresponding side plate 12 in the first horizontal direction, so as to realize the movably connected between the clamping assembly and the side plate 12.

[0055] The drive 42 can be connected with the guide 41. The drive 42 can drive the guide 41 to move, so that the clamping assembly connected with the guide 41 moves away from another clamping assembly in the same clamping mechanism 20, thereby realizing the tensioning of the sheet-shaped material 200 clamped by the clamping assembly.

[0056] In the embodiments of the present application, the structure of the guide 41 is not particularly limited. In some cases, as shown in Figure 5 The guide 41 can be in the form of a rod, and each tensioning mechanism 40 can include a plurality of guides 41. The plurality of guides 41 in each tensioning mechanism 40 can be arranged at intervals in the vertical direction; the guide 41 can extend along the first horizontal direction, one end of the guide 41 can be fixedly connected with the corresponding clamping member 23; and the guide 41 can pass through the corresponding side plate 12 along the first horizontal direction.

[0057] For example, the rod-shaped guide 41 can pass through the through slot on the side plate 12 matched with the guide 41, and be slidably connected with the guide 41 in the first horizontal direction, so as to movably connect the guide 41 with the side plate 12 in the first horizontal direction.

[0058] Exemplarily, the side plate 12 is provided with a through slot through which the rod-shaped guide 41 passes, and the cross-sectional area of the through slot in the side plate 12 is greater than the cross-sectional area of the guide 41; the side plate 12 corresponding to the tensioning mechanism 40 can be fixedly connected with a fixing member 121 on one side in the first horizontal direction, and the fixing member 121 can be provided with a through slot matched with the guide 41, the guide 41 can pass through the through slot in the fixing member 121 and be in sliding connection with the through slot in the fixing member 121 in the first horizontal direction, so that the guide 41 is movably connected with the side plate 12 in the first horizontal direction.

[0059] It can be understood that when the number of the clamping mechanisms 20 is multiple, each clamping mechanism 20 can be provided with multiple tensioning mechanisms 40 corresponding to one side in the first horizontal direction, and the number of the tensioning mechanisms 40 on the same side in the first horizontal direction can be equal to or greater than the number of the fixing members 121. Each fixing member 121 can be in sliding connection with the guide 41 in one or more tensioning mechanisms 40, and the embodiments of the present application are not limited in this regard.

[0060] In other cases, as shown in Figure 6 The guide 41 can be in the form of a plate, the guide 41 can extend in the vertical direction, and each tensioning mechanism 40 can include one guide 41; the guide 41 can pass through the corresponding side plate 12 in the first horizontal direction.

[0061] Exemplarily, the plate-shaped guide 41 can pass through the through slot in the side plate 12 matched with the guide 41 and be in sliding connection with the through slot in the first horizontal direction, so that the guide 41 is movably connected with the side plate 12 in the first horizontal direction.

[0062] It can be understood that when the number of the clamping mechanisms 20 is multiple, each clamping mechanism 20 can be provided with multiple tensioning mechanisms 40 corresponding to one side in the first horizontal direction, and the tensioning mechanisms 40 on the same side in the first horizontal direction can be in sliding connection with the same side plate 12, and the side plate 12 can be provided with multiple through slots spaced apart in the second horizontal direction.

[0063] Please refer to Figure 8 In some embodiments, the driving member 42 can be an elastic member. The driving member 42 can drive the clamping assembly connected therewith to move in the first horizontal direction by the elastic force of the driving member 42.

[0064] The driving member 42 can be a spring. The guide member 41 can be in the shape of a rod. The number of the driving members 42 can be equal to the number of the guide members 41, and the plurality of driving members 42 correspond to the plurality of guide members 41 one by one. The guide member 41 can include a connecting portion 411 and an abutting portion 412, and the connecting portion 411 and the abutting portion 412 can be integrally formed. The connecting portion 411 extends in the first horizontal direction, and one end of the connecting portion 411 is fixedly connected with the corresponding clamping member 23, and the other end is fixedly connected with the abutting portion 412. The cross-sectional area of the abutting portion 412 is greater than that of the connecting portion 411. The connecting portion 411 can pass through the corresponding side plate 12 in the first horizontal direction, and can be slidably connected to the fixed member 121 in the first horizontal direction. The driving member 42 can be sleeved on the connecting portion 411, and one end of the driving member 42 can abut against the abutting portion 412, and the other end can abut against the fixed member 121 or the side plate 12. The abutting portion 412 and the fixed member 121 can be located on both sides of the corresponding side plate 12 in the first horizontal direction, respectively.

[0065] The abutting portion 412 can push the driving member 42 from one side in the first horizontal direction, and the fixed member 121 or the side plate 12 can push the driving member 42 from the other side in the first horizontal direction, so that the driving member 42 is elastically deformed by being extruded in the first horizontal direction; the elastic force generated by the elastic deformation of the driving member 42 can drive the abutting portion 412 to move in the first horizontal direction away from the fixed member 121 and the side plate 12, so that the connecting portion 411 and the clamping assembly connected with the connecting portion 411 move synchronously, thereby moving the clamping assembly away from another clamping assembly in the same clamping mechanism 20, and realizing tensioning of the sheet-shaped material 200 clamped by the two clamping assemblies.

[0066] It can be understood that when the driving member 42 drives the guide member 41 and the clamping assembly to move synchronously by elastic force after being extruded, the driving member 42 can also be a rubber pad or the like, and the embodiments of the present application are not limited in this regard.

[0067] For example, as shown in FIG. 1, the base plate 11 is provided with a plurality of clamping mechanisms 20 arranged in the second horizontal direction. In each clamping mechanism 20, a plurality of clamping assemblies on the first side in the first horizontal direction are fixedly connected to the corresponding side plate 12 and are respectively connected to a plurality of electrode heads 30. A plurality of clamping assemblies on the second side in the first horizontal direction are movably connected to the corresponding side plate 12. A plurality of guide members 41 can be fixedly connected to the clamping member 23 in each movable clamping assembly. The plurality of guide members 41 on the same clamping member 23 are arranged in the vertical direction. A plurality of fixed members 121 are fixedly connected to the side plate 12 on the second side in the first horizontal direction.
