Description

Technical Field

[0001] The utility model relates to the technical field of battery production equipment, in particular to a battery core coating device. Background Art

[0002] In the production process of lithium-ion power batteries, it is necessary to attach an insulating film (blue glue) to the bare cell so that the insulating film wraps the surface of the bare cell to prevent damage to the internal electrode and prevent the electrode from overlapping with other metals and causing a short circuit. When the device of the related technology is coating, the insulating film cannot completely fit the surface of the cell, and the insulating film is easy to become fluffy and warp, thus scratching the surface of the cell. Utility Model Content

[0003] In view of the above problems, the present application provides a battery cell coating device, which aims to solve the problem that the insulating film cannot completely fit the surface of the battery cell, so as to prevent the insulating film from becoming fluffy and warping and scratching the surface of the battery cell.

[0004] The present application provides a battery cell coating device, comprising a workbench, a glue clamping mechanism and a glue rolling mechanism; the workbench has a coating platform, and the coating platform is configured to place an insulating film and a battery cell; the glue clamping mechanism is arranged on the workbench, and has a glue clamping member, and the glue clamping member can move relative to the workbench, and the glue clamping member is configured to clamp the side edge of the insulating film and drive the insulating film to move so that the insulating film is attached to the surface of the battery cell; the glue rolling mechanism is arranged on the workbench, and has a roller, and the roller can move and roll relative to the workbench to press the insulating film against the surface of the battery cell.

[0005] In the technical solution of the embodiment of the present application, when the technical solution of the utility model is used to coat the battery cell, the insulating film and the battery cell are first placed on the coating platform in sequence, so that the battery cell is above the insulating film, so that the insulating film is attached to the lower surface of the battery cell, and at this time, the side edge of the insulating film is exposed on the side of the battery cell; then the side edge of the insulating film is clamped by the clamping parts of the clamping mechanism, and the insulating film is driven to move toward the surface of the battery cell, so that the insulating film is attached to the surface of the battery cell; at the same time, the roller of the rolling mechanism can move relative to the workbench, so that the roller is close to the insulating film and moves and rolls along the attachment direction of the insulating film, so that the insulating film can be pressed against the surface of the battery cell, so that the insulating film can be completely attached to the surface of the battery cell. Therefore, this solution can effectively solve the problem that the insulating film cannot be completely attached to the surface of the battery cell, so as to prevent the insulating film from being fluffy and warping and scratching the surface of the battery cell.

[0006] In some embodiments, the glue rolling mechanism includes a horizontal driving mechanism and a lifting mechanism; the lifting mechanism is connected to the horizontal driving mechanism by transmission, and the horizontal driving mechanism drives the lifting mechanism to move along the first direction; the roller is rollably arranged on the lifting mechanism, and the lifting mechanism drives the roller to rise and fall. In such a design, the horizontal driving mechanism first drives the lifting mechanism and the roller to move toward the insulating film along the first direction until the roller is in close contact with the surface of the insulating film; then, the lifting mechanism drives the roller to rise, move and roll from the bottom to the top of the side surface of the battery cell, that is, the roller moves and rolls along the attachment direction of the insulating film to press the insulating film against the side surface of the battery cell. When the roller moves to the top of the side surface of the battery cell, the horizontal driving mechanism drives the lifting mechanism and the roller to move along the first direction again, so as to move and roll from one side to the other side of the upper surface of the battery cell, so as to press the insulating film against the upper surface of the battery cell. Therefore, the glue rolling mechanism can drive the roller to move along the side surface and upper surface of the battery cell under the action of the horizontal driving mechanism and the lifting mechanism, so as to fully press the insulating film against the side surface and upper surface of the battery cell.

[0007] In some embodiments, the lifting mechanism includes a first mounting frame, a first lifting component and a first buffer; the first mounting frame is connected to the horizontal driving mechanism by transmission; the first lifting component is arranged on the first mounting frame in a liftable manner; the roller is arranged on the first lifting component in a rollable manner; and the first buffer is connected to the first mounting frame and the first lifting component. With such a design, the first mounting frame can be used to connect the entire lifting mechanism to the horizontal driving mechanism by transmission, so as to facilitate the installation of the lifting mechanism. In addition, by using the first buffer connected to the first mounting frame and the first lifting component, when the roller is in close contact with the surface of the insulating film, the first buffer can play a buffering role, preventing the roller from generating excessive pressing force on the battery cell during the rolling process and damaging the battery cell, and can play a role in protecting the battery cell.

[0008] In some embodiments, the expansion and contraction direction of the first buffer is set at an angle to the lifting direction of the first lifting component. In such a design, since the direction of the pressing force applied by the roller to the insulating film is at an angle to the lifting direction of the first lifting component, by setting the expansion and contraction direction of the first buffer at an angle to the lifting direction of the first lifting component, the first buffer can apply a pulling force away from the insulating film to the first lifting component, so that the first buffer can effectively buffer the pressing force of the roller on the insulating film, thereby effectively buffering the pressing force on the battery cell, and improving the protection of the battery cell.

[0009] In some embodiments, the sandwich component can be moved and flipped relative to the workbench. Such a design can better drive the insulating film to move toward the surface of the battery cell when the sandwich component moves and flips, so as to pull the insulating film to cover the side surface and upper surface of the battery cell.

[0010] In some embodiments, the glue sandwich mechanism includes a second mounting frame, a second lifting component and a flipping component; the second mounting frame is connected to the horizontal driving mechanism by transmission; the second lifting component is arranged on the second mounting frame so as to be liftable; the flipping component is arranged on the second lifting component so as to be lifted and lowered along with the second lifting component, and the flipping component has a rotating shaft; the glue sandwich member is connected to the rotating shaft by transmission, and the rotating shaft drives the glue sandwich member to flip. With such a design, the entire glue sandwich mechanism can be connected to the horizontal driving mechanism by transmission by the second mounting frame to facilitate the installation of the glue sandwich mechanism. In addition, the lifting mechanism of the glue sandwich mechanism and the glue rolling mechanism can be synchronously driven to move along the first direction by the horizontal driving mechanism, which can not only make the glue sandwich mechanism and the glue rolling mechanism move synchronously, but also simplify the structural design.

[0011] In some embodiments, the flip mechanism further includes a second buffer, which is connected to the second mounting frame and the second lifting component. With such a design, by using the second buffer connected to the second mounting frame and the second lifting component, when the second lifting part drives the insulating film clamped on the rubber clamp to move, the second buffer can play a buffering role, preventing the rubber clamp from generating excessive pulling force on the insulating film during movement and damaging the insulating film, thereby protecting the insulating film.

[0012] In some embodiments, two second lifting parts and two flipping parts are provided, and the two second lifting parts are provided on both sides of the second mounting frame, and one flipping part is provided correspondingly to one second lifting part, and the clamping part is connected between the two flipping parts; a second buffer part is connected between one second lifting part and the second mounting frame. Such a design, by providing two second lifting parts and two flipping parts on both sides of the second mounting frame respectively, so as to connect the clamping part between the two flipping parts, can improve the stability of the clamping part during movement, thereby improving the accuracy of the insulating film attached to the surface of the battery cell.

[0013] In some embodiments, the adhesive sandwich component includes a mounting seat and two adhesive sandwiching rods; the mounting seat is transmission-connected to the rotating shaft; the two adhesive sandwiching rods are connected to the mounting seat, and an adhesive sandwiching space is formed between the two adhesive sandwiching rods. With such a design, the mounting seat can be used to connect the entire adhesive sandwich component to the rotating shaft of the flipping component, so that the adhesive sandwich component can be flipped under the rotation of the rotating shaft. In addition, by allowing the side edge of the insulating film to pass through the angle space between the two adhesive sandwiching rods, the edge of the insulating film can be fully clamped by the two adhesive sandwiching rods.

[0014] In some embodiments, there are two glue clamping mechanisms and two glue rolling mechanisms; the two glue clamping mechanisms are respectively arranged on both sides of the coating platform, and the two glue rolling mechanisms are respectively arranged on both sides of the coating platform, and the glue clamping parts of the two glue clamping mechanisms are respectively configured to clamp the edges of the two sides of the insulating film. With such a design, the left edge of the insulating film can be clamped by the glue clamping parts under the action of the glue clamping mechanism located on the left side of the coating platform, so as to attach the insulating film to the left side surface of the battery cell and the half of the upper surface close to the left side, and the insulating film can be pressed against the left side surface of the battery cell and the half of the upper surface close to the left side under the action of the glue rolling mechanism located on the left side of the coating platform; in addition, the right edge of the insulating film can be clamped by the glue clamping parts under the action of the glue clamping mechanism located on the right side of the coating platform, so as to attach the insulating film to the right side surface of the battery cell and the half of the upper surface close to the right side, and the insulating film can be pressed against the right side surface of the battery cell and the half of the upper surface close to the right side under the action of the glue rolling mechanism located on the right side of the coating platform. In this way, the insulating film can be automatically attached to the lower surface, left and right side surfaces and upper surface of the battery cell.

[0015] In some embodiments, a non-sticking layer is provided on the surface of the sandwich component, so that when the insulating film is clamped, the insulating film can be prevented from sticking to the sandwich component.

[0016] In some embodiments, the roller is a flexible member. With such a design, the flexible roller can further buffer the pressing force of the roller on the insulating film, thereby effectively buffering the pressing force on the battery cell and improving the protection of the battery cell.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0036] As a new type of secondary battery, lithium-ion power battery has the advantages of high energy density and power density, high operating voltage, light weight, small size, long cycle life, good safety, and green environmental protection. It has broad application prospects in portable appliances, power tools, large-scale energy storage, electric transportation power supply, etc.

[0037] In the production process of lithium-ion power batteries, it is necessary to attach an insulating film (blue glue) to the bare cell so that the insulating film wraps the surface of the bare cell to prevent damage to the internal pole piece and prevent the pole piece from overlapping with other metals and causing a short circuit. However, when using traditional devices for coating, the insulating film cannot completely fit the surface of the cell, and the insulating film is prone to fluffy and warping, which can scratch the surface of the cell.

[0038] Based on the above problems, the present invention proposes a cell film coating device 100 to solve the problem that the insulating film 200 cannot completely adhere to the surface of the cell 300, so as to prevent the insulating film 200 from becoming fluffy and warping and scratching the surface of the cell 300.

[0039] See also Figures 1 to 7 In one embodiment of the utility model, the battery cell coating device 100 includes a workbench 10, a glue clamping mechanism 20 and a glue rolling mechanism 30; the workbench 10 has a coating platform 11, and the coating platform 11 is configured to place an insulating film 200 and a battery cell 300; the glue clamping mechanism 20 is arranged on the workbench 10, and has a glue clamping member 25, and the glue clamping member 25 can move relative to the workbench 10, and the glue clamping member 25 is configured to clamp the side edge of the insulating film 200 and drive the insulating film 200 to move so that the insulating film 200 is attached to the surface of the battery cell 300; the glue rolling mechanism 30 is arranged on the workbench 10, and has a roller 33, and the roller 33 can move and roll relative to the workbench 10 to press the insulating film 200 against the surface of the battery cell 300.

[0040] It can be understood that the workbench 10 is a supporting component of the entire battery cell coating device 100 , and is used to support and fix components such as the glue clamping mechanism 20 and the glue rolling mechanism 30 .

[0041] The film coating platform 11 is a platform for carrying the insulating film 200 and the battery cell 300. In practical applications, the film coating platform 11 can be fixed relative to the workbench 10, or can be raised and lowered relative to the workbench 10 to adapt to the processing of battery cells 300 of different sizes.

[0042] In one embodiment, the cell coating device 100 may include a loading mechanism to sequentially place the insulating film 200 and the cell 300 on the coating platform 11. Of course, in other embodiments, the insulating film 200 and the cell 300 may be sequentially placed on the coating platform 11 by an external loading mechanism.

[0043] Optionally, the loading mechanism may be a robot arm, so as to realize an automatic loading process of the insulating film 200 and the battery cell 300 through the robot arm.

[0044] In practical applications, the clamping member 25 of the clamping mechanism 20 can move horizontally, move (lift or lower) vertically, or rotate relative to the workbench 10 , as long as it can drive the insulating film 200 to adhere to the surface of the battery cell 300 .

[0045] Furthermore, the clamping member 25 may be a clamping rod 252 or a clamping claw, as long as it can clamp the side edge of the insulating film 200 .

[0046] In this embodiment, the roller 33 of the glue rolling mechanism 30 can move in the horizontal direction relative to the workbench 10, or can move (lift and lower) in the vertical direction relative to the workbench 10 while rolling relative to the workbench 10. The roller 33 first moves in the horizontal direction relative to the workbench 10 so that the roller 33 moves toward the insulating film 200 until the roller 33 is in close contact with the surface of the insulating film 200; then, the roller 33 moves in the vertical direction relative to the workbench 10 (lift and lower) and moves and rolls from the bottom to the top of the side surface of the battery cell 300, that is, the roller 33 moves and rolls along the attachment direction of the insulating film 200 to press the insulating film 200 against the side surface of the battery cell 300. When the roller 33 moves to the top of the side surface of the battery cell 300, the roller 33 moves in the horizontal direction relative to the workbench 10 again to move and roll from one side of the upper surface of the battery cell 300 to the other side to press the insulating film 200 against the upper surface of the battery cell 300.

[0047] In summary, in the technical scheme of the embodiment of the present application, when the technical scheme of the utility model is used to coat the battery cell 300, the insulating film 200 and the battery cell 300 are first placed on the coating platform 11 in sequence, so that the battery cell 300 is above the insulating film 200, so that the insulating film 200 is attached to the lower surface of the battery cell 300, and at this time, the side edge of the insulating film 200 is exposed on the side of the battery cell 300; then, the side edge of the insulating film 200 is clamped by the clamping member 25 of the clamping mechanism 20, and the insulating film 200 is driven to move toward the surface of the battery cell 300, so that the insulating film 200 is attached to the surface of the battery cell 300; at the same time, the roller 33 of the rolling mechanism 30 can be moved relative to the workbench 10, so that the roller 33 is close to the insulating film 200 and moves and rolls along the attachment direction of the insulating film 200, so that the insulating film 200 can be pressed against the surface of the battery cell 300, so that the insulating film 200 can be completely attached to the surface of the battery cell 300. Therefore, this solution can effectively solve the problem that the insulating film 200 cannot completely adhere to the surface of the battery cell 300, so as to prevent the insulating film 200 from becoming fluffy and warping and scratching the surface of the battery cell 300.

[0048] See also Figure 2 , Figure 4 In one embodiment of the utility model, the rubber rolling mechanism 30 includes a horizontal driving mechanism 31 and a lifting mechanism 32; the lifting mechanism 32 is transmission-connected to the horizontal driving mechanism 31, and the horizontal driving mechanism 31 drives the lifting mechanism 32 to move along the first direction; the roller 33 is rotatably arranged on the lifting mechanism 32, and the lifting mechanism 32 drives the roller 33 to rise and fall.

[0049] With such a design, the horizontal driving mechanism 31 first drives the lifting mechanism 32 and the roller 33 to move toward the insulating film 200 along the first direction until the roller 33 is in close contact with the surface of the insulating film 200; then, the lifting mechanism 32 drives the roller 33 to rise, and moves and rolls from the bottom to the top of the side surface of the battery cell 300, that is, the roller 33 moves and rolls along the attachment direction of the insulating film 200 to press the insulating film 200 against the side surface of the battery cell 300. When the roller 33 moves to the top of the side surface of the battery cell 300, the horizontal driving mechanism 31 drives the lifting mechanism 32 and the roller 33 to move along the first direction again, and moves and rolls from one side to the other side of the upper surface of the battery cell 300, so that the insulating film 200 is pressed against the upper surface of the battery cell 300. Therefore, the rubber rolling mechanism 30 can drive the roller 33 to move along the side surface and upper surface of the battery cell 300 through the action of the horizontal driving mechanism 31 and the lifting mechanism 32 to fully press the insulating film 200 against the side surface and upper surface of the battery cell 300 .

[0050] In one embodiment, the horizontal driving mechanism 31 may include a cylinder or a motor.

[0051] Optionally, in order to improve the stability of the horizontal driving mechanism 31 driving the lifting mechanism 32 and the roller 33 to move in the first direction, a first slide rail extending along the first direction can be provided on the workbench 10, and a first slider can be provided on the lifting mechanism 32. During the movement of the lifting mechanism 32, the first slider slides in cooperation with the first slide rail.

[0052] See also Figure 4 In one embodiment of the utility model, the lifting mechanism 32 includes a first mounting frame 321, a first lifting component 322 and a first buffer component 323; the first mounting frame 321 is transmission-connected to the horizontal driving mechanism 31; the first lifting component 322 is liftably disposed on the first mounting frame 321; the roller 33 is rollably disposed on the first lifting component 322; the first buffer component 323 is connected to the first mounting frame 321 and the first lifting component 322.

[0053] With such a design, the first mounting frame 321 can be used to drive and connect the entire lifting mechanism 32 to the horizontal driving mechanism 31, so as to facilitate the installation of the lifting mechanism 32. In addition, by using the first buffer 323 connected to the first mounting frame 321 and the first lifting member 322, when the roller 33 is in close contact with the surface of the insulating film 200, the first buffer 323 can play a buffering role, preventing the roller 33 from generating an excessively large pressing force on the battery cell 300 during the rolling process and damaging the battery cell 300, and can play a role in protecting the battery cell 300.

[0054] In one embodiment, the first buffer member 323 may be a spring having a higher buffering capacity.

[0055] In one embodiment, the first lifting component 322 may include a driving portion and a mounting portion, wherein the driving portion is used to drive the mounting portion to rise and fall, and the drum 33 is mounted on the mounting portion.

[0056] Optionally, the driving part can be a cylinder or a motor. The mounting part can be designed as a frame, and mounting shaft holes are provided on opposite sides of the mounting part, and the two ends of the drum 33 are rotatably inserted into the two mounting shaft holes.

[0057] See also Figure 4 In one embodiment of the present invention, the telescopic direction of the first buffer member 323 is set at an angle to the lifting direction of the first lifting member 322 .

[0058] With such a design, since the direction of the pressing force applied by the roller 33 to the insulating film 200 is at an angle to the lifting direction of the first lifting component 322, by setting the extension and contraction direction of the first buffer 323 at an angle to the lifting direction of the first lifting component 322, the first buffer 323 can apply a pulling force on the first lifting component 322 away from the insulating film 200, so that the first buffer 323 can effectively buffer the pressing force of the roller 33 on the insulating film 200, thereby effectively buffering the pressing force on the battery cell 300, thereby enhancing the protection of the battery cell 300.

[0059] In one embodiment, in order to facilitate the installation of the first buffer component 323, a first hanging ear can be provided on one side of the first mounting frame 321, and a second hanging ear can be provided on one side of the first lifting component 322. The first buffer component 323 is provided with a first hook and a second hook at both ends. During the installation process, the first hook is hung on the first hanging ear, and the second hook is hung on the second hanging ear, so that the first buffer component 323 can be installed.

[0060] See also Figures 1 to 3 In one embodiment of the present invention, the clamping member 25 can be moved and turned over relative to the workbench 10 .

[0061] Such a design can better drive the insulating film 200 to move toward the surface of the battery cell 300 when the interlayer 25 moves and turns, so as to pull the insulating film 200 to cover the side surface and the upper surface of the battery cell 300 .

[0062] See also Figure 3 In one embodiment of the utility model, the clamping mechanism 20 includes a second mounting frame 21, a second lifting component 22 and a flipping component 23; the second mounting frame 21 is transmission-connected to the horizontal driving mechanism 31; the second lifting component 22 is liftably disposed on the second mounting frame 21; the flipping component 23 is disposed on the second lifting component 22 to be lifted and lowered along with the second lifting component 22, and the flipping component 23 has a rotating shaft; the clamping component 25 is transmission-connected to the rotating shaft, and the rotating shaft drives the clamping component 25 to flip.

[0063] With such a design, the entire glue sandwiching mechanism 20 can be connected to the horizontal driving mechanism 31 by the second mounting frame 21, so as to facilitate the installation of the glue sandwiching mechanism 20. In addition, the lifting mechanism 32 of the glue sandwiching mechanism 20 and the glue rolling mechanism 30 can be synchronously driven by the horizontal driving mechanism 31 to move along the first direction, which can not only make the glue sandwiching mechanism 20 and the glue rolling mechanism 30 move synchronously, but also simplify the structural design.

[0064] In this embodiment, first, the horizontal driving mechanism 31 drives the laminating mechanism 20 to move with the insulating film 200 along the first direction toward the battery cell 300, and at the same time, the lifting mechanism 32 and the roller 33 can be driven to move along the first direction toward the insulating film 200; then, the second lifting component 22 drives the flipping component 23 and the side edge of the insulating film 200 to rise, so that the insulating film 200 covers the side surface of the battery cell 300, and at the same time, the lifting mechanism 32 drives the roller 33 to rise, move and roll from the bottom to the top of the side surface of the battery cell 300, so as to press the insulating film 200 against the side surface of the battery cell 300; then, the flipping component 23 drives the side edge of the insulating film 200 to flip; then, the horizontal driving mechanism 31 drives the laminating mechanism 20 to move along the first direction again, so that the insulating film 200 covers the upper surface of the battery cell 300, and at the same time, the horizontal driving mechanism 31 can synchronously drive the roller 33 to move along the first direction, so as to press the insulating film 200 against the upper surface of the battery cell 300. Therefore, when the insulating film 200 is attached to the surface of the battery cell 300 by the laminating mechanism 20 , the roller 33 moves along the attaching direction of the insulating film 200 , so that the insulating film 200 can be fully pressed against the side surface and the upper surface of the battery cell 300 .

[0065] In one embodiment, the second lifting component 22 may include a driving part and a mounting part, the driving part is used to drive the mounting part to rise and fall, and the flipping component 23 is mounted on the mounting part.

[0066] Optionally, the driving part may be a cylinder or a motor.

[0067] See also Figure 3 In one embodiment of the utility model, the flipping mechanism further includes a second buffer member 24 , and the second buffer member 24 is connected to the second mounting frame 21 and the second lifting member 22 .

[0068] Such a design uses a second buffer member 24 connected to the second mounting frame 21 and the second lifting member 22. When the second lifting member drives the insulating film 200 clamped on the rubber clamping member 25 to move, the second buffer member 24 can play a buffering role to prevent the rubber clamping member 25 from generating excessive pulling force on the insulating film 200 during movement and damaging the insulating film 200, thereby protecting the insulating film 200.

[0069] In one embodiment, the second buffer member 24 may also be a spring with a higher buffering capacity.

[0070] See also Figure 3 In one embodiment of the utility model, two second lifting components 22 and two flipping components 23 are provided, the two second lifting components 22 are respectively arranged on both sides of the second mounting frame 21, a flipping component 23 is correspondingly arranged on a second lifting component 22, and the rubber clamping component 25 is connected between the two flipping components 23; a second buffer component 24 is connected between a second lifting component 22 and the second mounting frame 21.

[0071] Such a design, by respectively providing two second lifting parts and two flipping parts 23 on both sides of the second mounting frame 21 to connect the sandwich component 25 between the two flipping parts 23, can improve the stability of the sandwich component 25 during movement, thereby improving the accuracy of the insulating film 200 attached to the surface of the battery cell 300.

[0072] See also Figure 3 In one embodiment of the utility model, the clamping member 25 includes a mounting seat 251 and two clamping rods 252; the mounting seat 251 is transmission-connected to the rotating shaft; the two clamping rods 252 are connected to the mounting seat 251, and a clamping space 25a is formed between the two clamping rods 252.

[0073] With such a design, the entire rubber sandwich 25 can be connected to the rotating shaft of the flip component 23 by using the mounting seat 251, so that the rubber sandwich 25 can be flipped under the rotation of the rotating shaft. In addition, by allowing the side edge of the insulating film 200 to pass through the rubber sandwich space 25a between the two rubber sandwiching rods 252, the edge of the insulating film 200 can be fully clamped by the two rubber sandwiching rods 252.

[0074] In one embodiment, when the clamping mechanism 20 includes two second lifting components 22 and two flipping components 23, the clamping component 25 may include two mounting seats 251, and the two clamping rods 252 are connected between the two mounting seats 251, and the two mounting seats 251 are respectively connected to the rotating axes of the two flipping components 23, so that the clamping component 25 can be flipped more smoothly under the action of the two flipping components 23.

[0075] See also Figure 1 , Figure 2 , Figures 5 to 7 In one embodiment of the utility model, two glue clamping mechanisms 20 and two glue rolling mechanisms 30 are provided; the two glue clamping mechanisms 20 are respectively provided on both sides of the film coating platform 11, and the two glue rolling mechanisms 30 are respectively provided on both sides of the film coating platform 11, and the glue clamping parts 25 of the two glue clamping mechanisms 20 are respectively configured to clamp the two side edges of the insulating film 200.

[0076] With such a design, the left edge of the insulating film 200 can be clamped by the clamping member 25 under the action of the clamping mechanism 20 located on the left side of the film coating platform 11, so that the insulating film 200 is attached to the left side surface and the half of the upper surface close to the left side of the battery cell 300, and the insulating film 200 is pressed against the left side surface and the half of the upper surface close to the left side of the battery cell 300 under the action of the rolling mechanism 30 located on the left side of the film coating platform 11; in addition, the right edge of the insulating film 200 can be clamped by the clamping member 25 under the action of the clamping mechanism 20 located on the right side of the film coating platform 11, so that the insulating film 200 is attached to the right side surface and the half of the upper surface close to the right side of the battery cell 300, and the insulating film 200 is pressed against the right side surface and the half of the upper surface close to the right side of the battery cell 300 under the action of the rolling mechanism 30 located on the right side of the film coating platform 11. In this way, the insulating film 200 can be automatically attached to the lower surface, left and right side surfaces, and upper surface of the battery cell 300.

[0077] It should be noted that the lower surface, left and right side surfaces and upper surface of the battery cell 300 mentioned here are not the lower surface, left and right side surfaces and upper surface of the battery cell 300 in actual application state, but refer to the lower surface, left and right side surfaces and upper surface of the battery cell 300 in the encapsulated state.

[0078] See also Figure 3 In one embodiment of the present invention, a non-sticking layer is provided on the surface of the interlayer 25 .

[0079] Such a design, by providing an anti-sticking layer on the surface of the sandwich component 25 , can prevent the insulating film 200 from sticking to the sandwich component 25 when the insulating film 200 is clamped.

[0080] Exemplarily, the anti-sticking layer may be a Teflon coating.

[0081] See also Figure 4 In one embodiment of the present invention, the roller 33 is a flexible member.

[0082] With such a design, the flexible roller 33 can further buffer the pressing force of the roller 33 on the insulating film 200 , thereby effectively buffering the pressing force on the battery cell 300 and improving the protection effect on the battery cell 300 .

[0083] Exemplarily, the roller 33 may be a polyurethane high-flexible rubber roller.
