DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction 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.

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

[0025] In the description of the embodiments of the present application, the word "exemplary" or "for example" is used to mean "an example of" or "an example, only. Any implementation or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being superior or more advantageous than other implementation or design solutions. In fact, the use of the word "exemplary" or "for example" is intended to present concepts in a concrete manner.

[0026] Referring to Figure 1 , Figure 1 An embodiment of the present application provides a processing apparatus 100. The processing apparatus 100 can accommodate a plurality of sheet materials 200 and perform plating processing on the plurality of sheet materials 200.

[0027] 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.

[0028] 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.

[0029] Referring to Figure 2 and Figure 3 In an embodiment, the processing apparatus 100 can include a reaction furnace 101 and a tensioning device 102. The tensioning device 102 can clamp the 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 be supplied with a reaction gas and heated to heat the sheet materials 200 located in the reaction furnace 101, so that the sheet materials 200 react with the reaction gas to complete plating.

[0030] In the embodiments of the present application, the length direction of the processing apparatus 100 and the tensioning device 102 can be defined as a first horizontal direction, the width direction can be defined as a vertical direction, and the height direction can be defined as a vertical direction. For example, as shown in Figure 1 the first horizontal direction can be an X direction, the vertical direction can be a Y direction, and the vertical direction can be a Z direction.

[0031] The tensioning device 102 can include a plurality of tensioning mechanisms 10. The plurality of tensioning mechanisms 10 can be arranged at intervals in a second horizontal direction. Each tensioning mechanism 10 can clamp and tension one sheet material 200.

[0032] Each tensioning mechanism 10 can include two connecting rods 11, two sets of clamping assemblies 12 and two supporting assemblies 13. The two connecting rods 11 each extend along the first horizontal direction and are spaced apart in the vertical direction. The two sets of clamping assemblies 12 are respectively arranged on the two connecting rods 11. The number of clamping assemblies 12 in each set of clamping assemblies 12 is multiple, and the multiple clamping assemblies 12 are spaced apart in the first horizontal direction. Each clamping assembly 12 can clamp the sheet material 200, and the two sets of clamping assemblies 12 can clamp multiple positions on both sides of the sheet material 200 in the vertical direction. The two supporting assemblies 13 are spaced apart in the first horizontal direction, and each supporting assembly 13 is respectively and detachably connected to the end portions of the two connecting rods 11 in the vertical direction.

[0033] It can be understood that after the two supporting assemblies 13 are connected to the two connecting rods 11, the two connecting rods 11 can be maintained spaced apart in the vertical direction, and the two connecting rods 11 and the two supporting assemblies 13 can enclose a clamping space. The sheet material 200 can be located in the clamping space, and the two sets of clamping assemblies 12 can clamp the sheet material 200 located in the clamping assemblies 12. In this way, the clamping and fixing of one sheet material 200 by one tensioning mechanism 10 can be achieved.

[0034] Please refer to Figure 4 In some embodiments, each clamping assembly 12 can include a connecting seat 121, a guide rod 122, a telescopic piece 123, a first elastic piece 124 and a clamp 125. The connecting seat 121 can be provided with a movable slot 1211 extending through the connecting seat 121 along the second horizontal direction. The guide rod 122 can be provided with one or more. The guide rod 122 can extend along the vertical direction and be located in the movable slot 1211. The two ends of the guide rod 122 can be fixedly connected with the inner wall of the movable slot 1211. When the number of guide rods 122 is multiple, the multiple guide rods 122 are spaced apart in the first horizontal direction or the second horizontal direction.

[0035] The telescopic member 123 can include a movable part 1231 and an extension part 1232. The movable part 1231 is accommodated in the movable slot 1211, and the guide rod 122 is arranged through the movable part 1231 in the vertical direction. The movable part 1231 is slidingly connected to the guide rod 122 in the vertical direction, so that the movable part 1231 is movably arranged in the movable slot 1211 in the vertical direction. The extension part 1232 is in the shape of a rod, and the extension part 1232 extends in the vertical direction. One end of the extension part 1232 is fixedly connected to the side of the movable part 1231 away from the corresponding connecting rod 11, i.e., the side of the movable part 1231 facing the clamping space, and the other end is connected to the clamp 125. The extension part 1232 can be partially located in the movable slot 1211, and can be arranged through the connecting seat 121 in the vertical direction. The extension part 1232 can move synchronously with the movable part 1231. The clamp 125 can clamp one side of the sheet-shaped material 200 in the vertical direction.

[0036] The first elastic member 124 can be arranged between the movable part 1231 and the inner wall of the movable slot 1211 close to the clamp 125. The first elastic member 124 can drive the movable part 1231 to move close to the corresponding connecting rod 11 and away from the clamping space by the elastic force, so that the part of the sheet-shaped material 200 clamped by the clamp 125 keeps a tendency to move close to the corresponding connecting rod 11 of the clamp 125. In this way, after the two sets of clamping assemblies 12 on the two connecting rods 11 clamp the sheet-shaped material 200 on both sides, the sheet-shaped material 200 can be stretched by the elastic force of the plurality of first elastic members 124, so that the sheet-shaped material 200 is clamped and fixed, and at the same time, the sheet-shaped material 200 is tensioned in the vertical direction.

[0037] It can be understood that the clamping and tensioning of the sheet-shaped material 200 by the two sets of clamping assemblies 12 can keep the sheet-shaped material 200 in a tensioned state by the elastic force of the first elastic member 124 after the sheet-shaped material 200 is stretched due to high temperature (e.g., 500-600 degrees Celsius) during the coating process, thereby reducing the probability of deformation or wrinkling of the sheet-shaped material 200, and improving the processing effect of the sheet-shaped material 200.

[0038] It can be understood that the clamp 125 can adopt a common clamp with automatic clamping function in the related field. The embodiments of the present application do not limit this. For example, the clamp 125 can adopt a clamp provided with a torsional spring and capable of automatically clamping a part.

[0039] In the embodiments of the present application, the fixing mode during the fixed connection and fixed installation is not specifically limited. For example, the fixing mode can include, but is not limited to, bolt fixing, welding fixing, one-piece fixing, etc.

[0040] In the embodiments of the present application, the type of the first elastic member 124 is not specifically limited. For example, the first elastic member 124 can be, but is not limited to, a spring, a rubber block, etc.

[0041] For example, the first elastic member 124 can be a spring. The two ends of the first elastic member 124 can be fixedly connected to the movable part 1231 and the inner wall of the movable slot 1211, respectively. For another example, the first elastic member 124 can be a spring, and the first elastic member 124 can be sleeved on the guide rod 122 and abut against the movable part 1231 and the inner wall of the movable slot 1211.

[0042] It can be understood that in each clamping assembly 12, the number of the first elastic member 124 can be one or more, which is not limited in the embodiments of the present application. When the number of the first elastic member 124 in each clamping assembly 12 is more than one, the plurality of first elastic members 124 can be arranged at intervals in the first horizontal direction and / or the second horizontal direction.

[0043] In some embodiments, each clamp 125 is rotatably connected to the corresponding extension part 1232. Each connecting seat 121 can be movably connected to the connecting rod 11 in the first horizontal direction. Each tensioning mechanism 10 can further include a plurality of second elastic members 14. Among them, part of the second elastic members 14 are arranged on one connecting rod 11, and the remaining second elastic members 14 are arranged on the other connecting rod 11.

[0044] In each group of clamping assemblies 12, at least one second elastic member 14 is arranged between every two adjacent clamping assemblies 12. The second elastic member 14 can drive the two adjacent clamping assemblies 12 to move away from each other in the first horizontal direction, so that the plurality of clamping assemblies 12 can stretch the clamped sheet-shaped material 200 in the first horizontal direction. In this way, the tensioning mechanism 10 can realize the tensioning of the sheet-shaped material 200 in the vertical direction and the first horizontal direction.

[0045] It can be understood that the clamp 125 is rotatably connected to the extension part 1232, and the clamp 125 can rotate according to the stretching of the sheet-shaped material 200 during the heating of the sheet-shaped material 200, so that the sheet-shaped material 200 can be continuously clamped on the sheet-shaped material 200. Before the sheet-shaped material 200 is subjected to the film coating process, when the clamping device moves under the driving of the second elastic member 14, the clamp 125 can rotate while moving, and thus can stretch the sheet-shaped material 200 in a direction that forms an angle with the first horizontal direction and the vertical direction, so that the tensioning force of the tensioning mechanism 10 on the sheet-shaped material 200 can act on each position of the sheet-shaped material 200 in a direction that forms an angle with the first horizontal direction and the vertical direction. In this way, the uniformity of the tensioning of each position of the sheet-shaped material 200 can be improved, and the probability of damage to the clamped part of the sheet-shaped material 200 can be reduced.

[0046] In the embodiments of the present application, the type of the second elastic member 14 is not specifically limited. For example, the second elastic member 14 can be, but is not limited to, a spring, a rubber block, etc.

[0047] For example, the second elastic member 14 can be a spring. The second elastic member 14 can be sleeved on the corresponding connecting rod 11, and the two ends of the second elastic member 14 can abut against the two adjacent connecting seats 121 to drive the two connecting seats 121 to move away from each other and keep the tendency of moving away from each other.

[0048] In some embodiments, each support assembly 13 can include two inner rods 131 and a sleeve 132. The two inner rods 131 each extend in the vertical direction and are spaced apart in the vertical direction. The ends of the two inner rods 131 away from each other are sleeved on the ends of the two connecting rods 11, so as to achieve the detachable connection between the support assembly 13 and the connecting member. The ends of the two inner rods 131 close to each other are provided with outer threads in opposite screw directions.

[0049] The two ends of the sleeve 132 are provided with threaded holes, and the inner threads on the inner walls of the two threaded holes are in opposite screw directions. The two ends of the sleeve 132 are sleeved on the ends of the two inner rods 131 close to each other and are threadedly connected with the two inner rods 131. The rotation of the sleeve 132 can drive the two inner rods 131 to move away from each other, thereby increasing the distance between the two connecting rods 11. With the increase of the distance between the two connecting rods 11, the movable part 1231 can gradually approach the inner wall of the movable groove 1211 away from the connecting rod 11 and cooperate with the inner wall of the movable groove 1211 to compress the first elastic member 124. The elastic force generated after the compression of the first elastic member 124 can drive the clip 125 to keep the moving tendency of approaching the corresponding connecting rod 11, thereby strengthening the tension of the sheet-shaped material 200 in the vertical direction.

[0050] In other embodiments, of the two inner rods 131 in the support assembly 13, the sleeve 132 is rotatably connected to one of the inner rods 131 and is sleeved and threadedly connected to the other inner rod 131. In this way, when the sleeve 132 rotates, it can drive the inner rod 131 threadedly connected to the sleeve 132 to move away from the other inner rod 131, so as to increase the distance between the two connecting rods 11.

[0051] It can be understood that when each tensioning mechanism 10 is tensioning a sheet material 200, the plurality of clamping assemblies 12 in each set of clamping assemblies 12 can be driven to approach each other to compress the plurality of second elastic members 14 by manual or automated assistance, and then the clamps 125 can be clamped on the flattened sheet material 200 between the two connecting rods 11. Then the staff or automated equipment can release the compression of the second elastic members 14, and the plurality of clamping assemblies 12 can be driven to move away from each other to achieve tensioning of the sheet material 200 in the first horizontal direction.

[0052] Then, the staff can set the two ends of the two support assemblies 13 on the two connecting rods 11, and drive the two connecting rods 11 to move away from each other by rotating the two sleeves 132, so as to compress the plurality of first elastic members 124 and achieve tensioning of the sheet material 200 in the vertical direction. In this way, the clamping and tensioning of one sheet material 200 by one tensioning mechanism 10 can be achieved.

[0053] In some embodiments, the tensioning device 102 can further include a carrier 20. The carrier 20 can carry a plurality of tensioning mechanisms 10 to achieve carrying of a plurality of sheet materials 200. The plurality of tensioning mechanisms 10 can be arranged at intervals in the second horizontal direction to achieve interval arrangement of the plurality of sheet materials 200 on the carrier 20. The carrier 20 can be received on a moving seat or hoisted on a hoisting frame, and movement of the moving seat or hoisting frame can drive the tensioning device 102 to move synchronously, thereby achieving movement of the plurality of sheet materials 200.

[0054] For example, the two sides of the carrier 20 can be fixedly connected with handles 23. A carrying device can support the two handles 23 to lift the tensioning device 102. The carrying device can move the lifted tensioning device 102 to achieve movement of the plurality of sheet materials 200. The carrying device can move the tensioning device 102 into or out of the reaction furnace 101 to achieve feeding and discharging of the sheet materials 200.

[0055] Please refer to Figure 5 In some embodiments, the carrier 20 can include two support portions 21 and a plurality of connecting portions 22. The two support portions 21 are arranged at intervals in the first horizontal direction, and the interval space between the two support portions 21 can accommodate the plurality of tensioning mechanisms 10 and the sheet materials 200 clamped by the tensioning mechanisms 10. The plurality of connecting portions 22 can be fixedly connected with the two support portions 21 to achieve relative fixation of the two support portions 21.

[0056] Each support part 21 is provided with a plurality of support grooves 211 and a plurality of positioning grooves 212 on a side facing another support part 21, each support groove 211 penetrates a top of the corresponding support part 21 in the vertical direction, and each positioning groove 212 penetrates a bottom of the corresponding support part 21 in the vertical direction. The plurality of support grooves 211 and the plurality of positioning grooves 212 correspond to each other. Meanwhile, the plurality of support grooves 211 on one support part 21 correspond to the plurality of support grooves 211 on another support part 21, and the plurality of positioning grooves 212 on one support part 21 correspond to the plurality of positioning grooves 212 on another support part 21. On each support part 21, the plurality of support grooves 211 are arranged in the second horizontal direction, and the plurality of positioning grooves 212 are arranged in the second horizontal direction. Each support groove 211 and the corresponding positioning groove 212 can cooperate to limit the movement of one tensioning mechanism 10.

[0057] Each support groove 211 can accommodate one end of the connecting rod 11 located at the top in the vertical direction in the corresponding tensioning mechanism 10, and the bottom wall of the support groove 211 can receive the corresponding connecting rod 11; each positioning groove 212 can accommodate one end of the connecting rod 11 located at the bottom in the vertical direction in the corresponding tensioning mechanism 10, and the connecting rod 11 can be slidingly fitted with the inner wall of the corresponding positioning groove 212 in the vertical direction and can be rotationally fitted with the inner wall of the corresponding positioning groove 212. The depth of the support groove 211 in the vertical direction is less than the depth of the positioning groove 212 in the vertical direction.

[0058] It can be understood that when the worker places the tensioning mechanism 10 clamping the sheet material 200 on the support frame 20, the worker can first move the two ends of the connecting rod 11 located at the bottom in the corresponding two positioning grooves 212, and then move the tensioning mechanism 10 upward to a height at which the connecting rod 11 located at the top is higher than the height at which the corresponding support groove 211 is located. Then, the worker can rotate the tensioning mechanism 10 and place the two ends of the connecting rod 11 located at the top in the corresponding two support grooves 211. At this time, the bottom wall of the support groove 211 can support the corresponding tensioning mechanism 10 in the vertical direction, and the inner walls of the positioning groove 212 and the support groove 211 can limit the movement of the tensioning mechanism 10 in the first horizontal direction and the second horizontal direction, thereby achieving the fixation of the tensioning mechanism 10 on the support frame 20.

[0059] Please refer to Figure 6 and Figure 7In some embodiments, the support groove 211 and the positioning groove 212 are not formed on the support portion 21. A plurality of receiving grooves 213 are formed on one side of each support portion 21 facing the other support portion 21. Each receiving groove 213 extends in the vertical direction and penetrates the top of the corresponding support portion 21 in the vertical direction. The plurality of receiving grooves 213 are spaced apart in the second horizontal direction. The depth of the receiving groove 213 in the vertical direction is greater than the distance between the two connecting rods 11 of the tensioning mechanism 10 to be loaded on the carrier 20 in the vertical direction. After the connecting rods 11 are aligned with the receiving grooves 213 and placed into the receiving grooves 213, the tensioning mechanism 10 can be fixed on the carrier 20.

[0060] Each receiving groove 213 can receive the end portions of the two connecting rods 11 of the same tensioning mechanism 10, and the bottom wall of the receiving groove 213 can support the connecting rods 11 at the bottom, thereby supporting the tensioning mechanism 10. The inner wall of the receiving groove 213 can limit the movement of the tensioning mechanism 10 in the first horizontal direction and the second horizontal direction, thereby fixing the tensioning mechanism 10 on the carrier 20.

[0061] It can be understood that when the bottom wall of the receiving groove 213 supports the corresponding connecting rod 11, the support assembly 13 in the same tensioning mechanism 10 can support the other connecting rod 11 in the same tensioning mechanism 10.

[0062] In the embodiments of the present application, the shape, number and connection position of the connecting portion 22 on the support portion 21 are not specifically limited. For example, the connecting portion 22 can be fixedly connected to the two sides of the two support portions 21 in the second horizontal direction and extend in the first horizontal direction; a plurality of connecting portions 22 are connected to each support portion 21, and the plurality of connecting portions 22 are spaced apart in the second horizontal direction and / or the vertical direction.
