Description

Technical Field

[0001] This invention belongs to the technical field of battery film application equipment, and relates to an insulating film application machine, particularly an insulating film application machine for the bottom of a new energy lithium battery module. Background Technology

[0002] Lithium-ion batteries are mainly used in new energy vehicles. During manufacturing, lithium-ion batteries require an insulating film to be applied to the outside for insulation. In related technologies, the insulating film is first cut to a certain length from a film roll, and then rolled and adhered to the bare lithium-ion battery using a pressure roller.

[0003] However, the discontinuous feeding of existing equipment can cause fluctuations in the tension of the film material, which in turn affects the bonding accuracy. Uneven tension during film bonding can cause the film material to stretch or loosen, resulting in bubbles, curling edges, or misalignment during bonding. Since the film material is mostly high-value functional material, material breakage or misalignment can lead to the scrapping of the entire section. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a bottom insulating film applicator for new energy lithium battery modules. The technical problem this invention aims to solve is: how to achieve film applicability to the bottom of the battery, realize complete insulation of the battery module, avoid the problem of rebound and peeling caused by manual film application, and improve the quality and efficiency of film application.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A bottom insulating film applicator for new energy lithium battery modules includes an applicator frame and a film material rack fixed on the applicator frame. A film material roll is rotatably connected to the film material rack, and multiple tension rollers are arranged and rotatably connected on the film material rack. An equipment cavity is formed within the equipment cavity, and a pair of guide grooves are formed within the equipment cavity. A film material traction frame is slidably arranged between the two guide grooves, and a film material conveying assembly is arranged within the film material traction frame. A pair of magnets are fixed on the film material traction frame. A film material end fixing frame is slidably arranged between the two guide grooves, and a pair of magnets attracted to the magnets are fixed on the film material end fixing frame. A fixing groove is formed in the equipment cavity, and a protrusion extends from the film material end fixing frame. A buckle is formed on the protrusion portion of the film material end fixing frame. The machine has holes and fixed slots with electric push rods fixed on both sides. Each electric push rod has a buckle rod fixed at its output end. One end of each buckle rod is inserted into the corresponding buckle hole. The film end fixing frame is equipped with an end fixing component and a winding cavity is provided inside the film end fixing frame. A winding wheel is provided inside the winding cavity. One end of the drive rope is fixed on the winding wheel. The other end of the drive rope is fixedly connected to the film traction frame. A coil spring is fixed at the shaft of the winding wheel. A placement plate is fixed on the film applicator frame. A placement opening is provided on the placement plate. Multiple battery fixing components are fixed on the placement plate around the placement opening. A film pressing frame is slidably connected inside the equipment cavity. An anti-static silicone block is fixed at the top of the film pressing frame. A cutting component is provided on the film pressing frame.

[0007] The working principle of this invention is as follows: Film material on a film roll is staggered across multiple tension rollers. One end of the film material passes through a film material traction frame and is fixedly engaged with a film material end fixing frame. The film material traction frame moves, causing the film material end fixing frame to move synchronously, thus conveying the film material. When the extended protrusion of the film material end fixing frame is inserted into the fixing groove, an electric push rod inserts a buckle rod into the buckle hole, fixing the film material end fixing frame to one side of the equipment cavity. This allows the film material to be conveyed directly below the bottom of the battery. Then, the pressure frame is raised, causing the anti-static silicone block to lift the film material portion, allowing the film material to contact the battery. The membrane is applied by contacting the bottom of the pool. The anti-static silicone block has its own resilience and deformation capabilities, which makes the membrane application process more efficient and improves the effect. After the membrane is applied, the cutting component cuts the usable portion of the membrane material to facilitate stable operation of the entire membrane application process. After the membrane application is completed, the electric push rod drives the buckle rod to disengage from the buckle hole, causing the coil spring to lose its restraint and drive the winding wheel to rotate. The drive rope is continuously wound up, making the gap between the membrane material end fixing frame and the membrane material traction frame smaller and smaller until they attract and connect with each other. This restores the membrane material delivery and the limiting fixation of one end of the membrane material, improving the overall operating effect and efficiency.

[0008] The film material conveying assembly includes a film material passage opening within a film material traction frame, two pairs of equipment blocks slidably connected within the film material passage opening, a set of traction rollers rotatably connected between each pair of equipment blocks, a conveyor belt connected to each set of traction rollers, and each conveyor belt fixedly connected end to end. Multiple transmission worm gears are rotatably connected within each equipment block, and a transmission worm is rotatably connected within each equipment block, meshing with a corresponding transmission worm gear. A transmission gear is provided outside each equipment block, and each transmission gear is coaxially fixedly connected to a corresponding transmission worm. A servo motor is fixed within each equipment block, and a transmission gear is coaxially fixedly connected to the output shaft of each servo motor, meshing with a corresponding transmission gear. An electric cutter is fixed within the film material passage opening.

[0009] Using the above structure, the film material is passed through the film material passage opening, and two conveyor belt structures are formed by each set of traction rollers and corresponding conveyor belts. The servo motor drives the transmission gear 2 to rotate, the transmission gear 2 drives the transmission gear 1 to rotate, the transmission gear 1 drives the transmission worm gear 1 to rotate, and the transmission worm gear 1 drives multiple transmission worm wheels 1 to rotate. Each set of transmission worm wheels 1, after rotating, cooperates with the conveyor belt to form the overall operation of the two conveyor belt structures, thereby conveying the film material.

[0010] A pair of bidirectional lead screws are rotatably connected inside the film material traction frame. The threaded sections on both sides of each bidirectional lead screw are threaded to the corresponding equipment block. One end of each bidirectional lead screw is coaxially fixedly connected to a transmission bevel gear. A transmission rod is rotatably connected inside the film material traction frame. Both ends of the transmission rod are coaxially fixedly connected to transmission bevel gears. Each transmission bevel gear meshes with the corresponding transmission bevel gear. A servo motor is fixed inside the film material traction frame. The output shaft of the servo motor is coaxially fixedly connected to the transmission rod.

[0011] Using the above structure, the transmission rod can be rotated by the second servo motor. After the transmission rod rotates, it will drive the second transmission bevel gear to rotate. After the second transmission bevel gear rotates, it will drive the first transmission bevel gear to rotate. After the first transmission bevel gear rotates, it will drive the first bidirectional lead screw to rotate. After the first bidirectional lead screw rotates, it will drive the two equipment blocks to perform a clamping action. This allows the two conveyor belt structures to adjust the distance between each other, better match the film thickness, and can clamp and fix the film when the conveyor belt structure is not operating, improving the stability of the subsequent film application effect.

[0012] The end fixing assembly includes a limiting groove on the film end fixing frame, a pair of meshing gears rotatably connected inside the film end fixing frame, a pair of limiting cylinders rotatably connected inside the limiting groove, each meshing gear being coaxially fixedly connected to the corresponding limiting cylinder, a clamping protrusion fixed on the surface of each limiting cylinder, a servo motor three fixed inside the film end fixing frame, the output shaft of the servo motor three being coaxially fixedly connected to one of the meshing gears, and an electric cutting knife two fixed at the opening of the limiting groove.

[0013] With the above structure, one of the meshing gears can be rotated by a servo motor. Since the two meshing gears mesh with each other, when one meshing gear rotates, the other meshing gear will also rotate in the opposite direction, causing the corresponding limiting cylinder to rotate synchronously. In this way, by rotating the two limiting cylinders, the two clamping protrusions can clamp and fix one end of the film material.

[0014] The battery fixing assembly includes multiple fixing frames fixed on the placement plate, each fixing frame is fixed with an electric push rod II, and the output end of each electric push rod II is fixed with a contact block, each contact block is pressed against the surface of the battery.

[0015] With the above structure, the contact blocks can be pushed against the battery surface by an electric push rod, and multiple contact blocks can press against the battery surface simultaneously to form a fixing effect, thereby improving the battery installation and fixing effect, and improving the battery disassembly and assembly effect.

[0016] The cutting assembly includes a cutting frame plate slidably connected within a pressing frame, a pair of racks fixed within the cutting frame plate, a cutting edge at the top of the cutting frame plate, and a pair of drive gears rotatably connected within the pressing frame. Each drive gear meshes with a corresponding rack, and a transmission gear three is coaxially fixedly connected between the two drive gears. A servo motor four is fixed within the pressing frame, and the output shaft of the servo motor four is coaxially fixedly connected to the transmission gear four, which meshes with the transmission gear three.

[0017] With the above structure, the servo motor four drives the transmission gear four to rotate, the transmission gear four drives the transmission gear three to rotate, and the transmission gear three drives the two drive gears to rotate. After the two drive gears rotate, they will mesh with the rack and pinion to drive the entire cutting frame to move up and down, thus achieving the cutting effect.

[0018] A pair of adjusting screws are rotatably connected inside the film applicator frame, and a pair of transmission bevel gears are rotatably connected inside the film applicator frame. Each transmission bevel gear is coaxially fixedly connected to the corresponding adjusting screw. The left and right sides of the film pressing frame are threadedly connected to the corresponding adjusting screws. A drive rod is rotatably connected inside the film applicator frame, and both ends of the drive rod are coaxially fixedly connected to transmission bevel gears. Each transmission bevel gear meshes with the corresponding transmission bevel gear. A transmission gear seven is coaxially fixedly connected to the drive rod. A servo motor five is fixed inside the film applicator frame, and the output shaft of the servo motor five is coaxially fixedly connected to a transmission gear eight, which meshes with the transmission gear seven.

[0019] Using the above structure, the servo motor five drives the transmission gear eight to rotate. After the transmission gear eight rotates, it drives the transmission gear seven to rotate. After the transmission gear seven rotates, it drives the drive rod to rotate. The drive rod drives the two transmission bevel gears four to rotate. The transmission bevel gears four drive the transmission bevel gear three to rotate. After the transmission bevel gear three rotates, it drives the control screw to rotate, thereby achieving the up and down movement of the pressing frame.

[0020] A pair of drive screws are rotatably connected inside the film applicator frame, and a pair of transmission bevel gears are rotatably connected inside the film applicator frame. Each transmission bevel gear is coaxially fixedly connected to the corresponding drive screw. The left and right sides of the film material traction frame are threadedly connected to the corresponding drive screws. A drive rod is rotatably connected inside the film applicator frame, and both ends of the drive rod are coaxially fixedly connected to transmission bevel gears. Each transmission bevel gear meshes with the corresponding transmission bevel gear. A transmission gear is coaxially fixedly connected to the drive rod. A servo motor is fixed inside the film applicator frame, and the output shaft of the servo motor is coaxially fixedly connected to a transmission gear. The transmission gears mesh with the transmission gears.

[0021] Using the above structure, the servo motor six drives the transmission gear six to rotate. After the transmission gear six rotates, it drives the transmission gear five to rotate. After the transmission gear five rotates, it drives the drive rod to rotate. The drive rod drives the two transmission bevel gears six to rotate. The transmission bevel gears six drive the transmission bevel gear five to rotate. After the transmission bevel gear five rotates, it drives the drive screw to rotate, thereby realizing the movement capability of the film material traction frame.

[0022] Compared with existing technologies, this new energy lithium battery module bottom insulating film applicator has the following advantages:

[0023] 1. The film is lifted by the pressure frame, which allows the antistatic silicone block to lift the film material so that the film material can contact the bottom of the battery to achieve the film application. The antistatic silicone block itself has the ability to rebound and deform, which makes the film application work better and improves the film application effect.

[0024] 2. After the film application is completed, the electric push rod drives the buckle rod to disengage from the buckle hole, causing the coil spring to lose its restraint. This causes the winding wheel to rotate and continuously wind up the drive rope. As the drive rope is continuously wound up, the gap between the film end fixing frame and the film traction frame becomes smaller and smaller until the two are attracted to each other and connected. This allows the film material to be conveyed and the film end to be fixed again, improving the overall operating effect and efficiency. Attached Figure Description

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0035] like Figures 1-8As shown, a bottom insulating film applicator for a new energy lithium battery module includes an applicator frame 1, a film material rack 2 fixed on the applicator frame 1, a film material roll 3 rotatably connected to the film material rack 2, and multiple tension rollers 4 arranged and rotatably connected on the film material rack 2. An equipment cavity 5 is formed inside the film material rack 2, and a pair of guide grooves 6 are formed inside the equipment cavity 5. A film material traction frame 7 is slidably arranged between the two guide grooves 6, and a film material conveying assembly is arranged inside the film material traction frame 7. A pair of magnets 8 are fixed on the film material traction frame 7. A film material end fixing frame 9 is slidably arranged between the two guide grooves 6, and a pair of magnets 10 attracted to the magnets 8 are fixed on the film material end fixing frame 9. A fixing groove 11 is formed in the equipment cavity 5, and a protrusion extends from the film material end fixing frame 9. A snap-fit ​​hole 12 is formed on the protrusion of the film material end fixing frame 9, and the fixing groove 11 has two protrusions on the left and right sides. An electric push rod 13 is fixed to the side. Each electric push rod 13 has a buckle rod 14 fixed to its output end. One end of each buckle rod 14 is inserted into a corresponding buckle hole 12. An end fixing component is provided in the film material end fixing frame 9. A winding cavity 15 is provided in the film material end fixing frame 9. A winding wheel 16 is provided in the winding cavity 15. One end of a drive rope 66 is fixed on the winding wheel 16. The other end of the drive rope 66 is fixedly connected to the film material traction frame 7. A coil spring 17 is fixed at the shaft of the winding wheel 16. A placement plate 18 is fixed on the film applicator frame 1. A placement opening 19 is provided on the placement plate 18. Multiple battery fixing components are fixed on the placement plate 18 around the placement opening 19. A film pressing frame 20 is slidably connected in the equipment cavity 5. An anti-static silicone block 21 is fixed to the top of the film pressing frame 20. A cutting component is provided on the film pressing frame 20.

[0036] The film material on the film roll 3 is staggered on multiple tension rollers 4, and one end of the film material passes through the film material traction frame 7 and is fixedly engaged with the film material end fixing frame 9. The film material traction frame 7 moves, which in turn drives the film material end fixing frame 9 to move synchronously, thus conveying the film material. When the extended protrusion of the film material end fixing frame 9 is inserted into the fixing groove 11, the electric push rod 13 inserts the buckle rod 14 into the buckle hole 12, fixing the film material end fixing frame 9 to one side of the equipment cavity 5. This allows the film material to be conveyed directly below the bottom of the battery. Then, the pressure frame 20 is lifted, causing the antistatic silicone block 21 to push up the film material, allowing the film material to contact the bottom of the battery. Contact is made to achieve the film application work. The anti-static silicone block 21 has its own elasticity and deformation ability, which makes the film application work better and improves the film application effect. After the film application is completed, the film material is cut by the cutting component to facilitate the stable operation of the overall film application work. After the film application work is completed, the electric push rod 13 drives the buckle rod 14 to disengage from the buckle engagement with the buckle hole 12, so that the coil spring 17 is unrestrained and drives the winding wheel 16 to rotate, continuously winding the drive rope 66. The drive rope 66 is continuously wound up, so that the gap between the film material end fixing frame 9 and the film material traction frame 7 becomes smaller and smaller until the two are attracted and connected to each other, thus realizing the film material delivery and the limiting fixation of one end of the film material, improving the overall operation effect and efficiency.

[0037] The film material conveying assembly includes a film material passage 22 opened in the film material traction frame 7, two pairs of equipment blocks 23 slidably connected in the film material passage 22, a set of traction rollers 24 rotatably connected between the two pairs of equipment blocks 23, a conveyor belt 25 connected to each set of traction rollers 24, each conveyor belt 25 being fixedly connected end to end, multiple transmission worm gears 26 rotatably connected in each equipment block 23, a transmission worm 27 rotatably connected in each equipment block 23, the transmission worm 27 meshing with the corresponding transmission worm gear 26, and a transmission gear 28 provided on the outside of each equipment block 23, each transmission gear 28 being coaxially fixedly connected with the corresponding transmission worm 27, a servo motor 29 fixed in each equipment block 23, and a transmission gear 30 coaxially fixedly connected to the output shaft of each servo motor 29, each transmission gear 30 meshing with the corresponding transmission gear 28, and an electric cutter 31 fixed in the film material passage 22.

[0038] Using the above structure, the film material can be passed through the film material passage 22, and two conveyor belt structures can be formed by each set of traction rollers 24 and the corresponding conveyor belt 25. The servo motor 29 drives the transmission gear 30 to rotate, the transmission gear 30 drives the transmission gear 28 to rotate, the transmission gear 28 drives the transmission worm gear 27 to rotate, and the transmission worm gear 27 drives multiple transmission worm wheels 26 to rotate. Each set of transmission worm wheels 26, after rotating, cooperates with the conveyor belt 25 to form the overall operation of the two conveyor belt structures, thereby conveying the film material.

[0039] A pair of bidirectional lead screws 32 are rotatably connected inside the film material traction frame 7. The threaded sections on both sides of each bidirectional lead screw are threadedly connected to the corresponding equipment block 23. One end of each bidirectional lead screw 32 is coaxially fixedly connected to a transmission bevel gear 33. A transmission rod 34 is rotatably connected inside the film material traction frame 7.

[0040] With the above structure, the transmission rod 34 can be rotated by the servo motor 36. After the transmission rod 34 rotates, it will drive the transmission bevel gear 35 to rotate. After the transmission bevel gear 35 rotates, it will drive the transmission bevel gear 33 to rotate. After the transmission bevel gear 33 rotates, it will drive the bidirectional lead screw 32 to rotate. After the bidirectional lead screw 32 rotates, it will drive the two equipment blocks 23 to perform a clamping action.

[0042] With the above structure, one of the meshing gears 38 can be rotated by the servo motor 341. Since the two meshing gears 38 mesh with each other, when one meshing gear 38 rotates, the other meshing gear 38 will also rotate in the opposite direction, so that the corresponding limiting cylinder 39 will also rotate synchronously. In this way, by rotating the two limiting cylinders 39, the two clamping protrusions 40 can clamp and fix one end of the film material.

[0043] The battery fixing assembly includes multiple fixing brackets 43 fixed on the placement plate 18, each fixing bracket 43 is fixed with an electric push rod 44, and each electric push rod 44 has a contact block 45 fixed at its output end, and each contact block 45 is pressed against the surface of the battery.

[0044] With the above structure, the contact block 45 can be pushed by the electric push rod to press against the battery surface. Multiple contact blocks 45 press against the battery surface simultaneously to form a fixing effect, thereby improving the battery installation and fixing effect, and improving the battery disassembly and assembly effect.

[0045] The cutting assembly includes a cutting frame plate 46 slidably connected within the film pressing frame 20, a pair of racks 47 fixed within the cutting frame plate 46, a cutting edge at the top of the cutting frame plate 46, and a pair of drive gears 48 rotatably connected within the film pressing frame 20.

After the two drive gears 48 rotate, they will mesh with the rack 47 to drive the entire cutting frame plate 46 to move up and down, so as to achieve the cutting effect.

[0047] A pair of adjusting screws 52 are rotatably connected inside the film applicator frame 1. A pair of transmission bevel gears 53 are also rotatably connected inside the film applicator frame 1. Each transmission bevel gear 53 is coaxially fixedly connected to the corresponding adjusting screw 52. The left and right sides of the film pressing frame 20 are threadedly connected to the corresponding adjusting screws 52. A drive rod 54 is rotatably connected inside the film applicator frame 1. Both ends of the drive rod 54 are coaxially fixedly connected to transmission bevel gears 55. Each transmission bevel gear 55 meshes with the corresponding transmission bevel gear 53. A transmission gear 56 is coaxially fixedly connected to the drive rod 54. A servo motor 57 is fixed inside the film applicator frame 1. The output shaft of the servo motor 57 is coaxially fixedly connected to a transmission gear 58. The transmission gear 58 meshes with the transmission gear 56.

[0048] Using the above structure, the servo motor 57 drives the transmission gear 8 58 to rotate. After the transmission gear 8 58 rotates, it drives the transmission gear 7 56 to rotate. After the transmission gear 7 56 rotates, it drives the drive rod 54 to rotate. The drive rod 54 drives the two transmission bevel gears 4 55 to rotate. The transmission bevel gears 4 55 drive the transmission bevel gear 3 53 to rotate. After the transmission bevel gear 3 53 rotates, it drives the control screw 52 to rotate, thereby achieving the up and down movement of the pressure film frame 20.

[0049] A pair of drive screws 59 are rotatably connected inside the film applicator frame 1. A pair of transmission bevel gears 60 are also rotatably connected inside the film applicator frame 1. Each transmission bevel gear 60 is coaxially fixedly connected to the corresponding drive screw 59.

The output shaft of the servo motor 57 is coaxially fixedly connected to a transmission gear 65. Transmission gears 63 and 65 mesh.

[0050] Using the above structure, the servo motor 64 drives the transmission gear 65 to rotate. After the transmission gear 65 rotates, it drives the transmission gear 63 to rotate. After the transmission gear 63 rotates, it drives the drive rod 61 to rotate. The drive rod 61 drives the two transmission bevel gears 62 to rotate. The transmission bevel gears 62 drive the transmission bevel gear 60 to rotate. After the transmission bevel gear 60 rotates, it drives the drive screw 59 to rotate, thereby realizing the movement capability of the film material traction frame 7.

[0051] The working principle of this invention is as follows: The film material on the film roll 3 is staggered on multiple tension rollers 4, and one end of the film material passes through the film material passage opening 22. A servo motor 26 drives a transmission rod 34 to rotate, which in turn drives a transmission bevel gear 25 to rotate. The transmission bevel gear 25 then drives a transmission bevel gear 13 to rotate, which in turn drives a bidirectional lead screw 12 to rotate. The bidirectional lead screw 12 then drives two device blocks 23 to perform a clamping action, thereby allowing the two conveyor belt structures to adjust their spacing so that the surfaces of the upper and lower conveyor belts 25 contact the film material. A servo motor 19 drives a transmission gear 20 to rotate, which in turn drives the transmission gear 20 to rotate... The drive gear 28 rotates, which in turn drives the drive worm gear 27 to rotate. The drive worm gear 27 then drives multiple drive worm wheels 26 to rotate. Each set of drive worm wheels 26, when rotated, engages with the conveyor belt 25, forming two conveyor belt structures to transport the film material. When one end of the film material enters the limiting groove 37, the servo motor 41 drives one of the meshing gears 38 to rotate. Because the two meshing gears 38 are meshed, when one meshing gear 38 rotates, the other meshing gear 38 rotates in the opposite direction, causing the corresponding limiting cylinder 39 to rotate synchronously. This rotation of the two limiting cylinders 39 allows the two clamping protrusions 40 to... The membrane material is clamped and fixed at one end. A servo motor 64 drives a transmission gear 65 to rotate. The rotation of transmission gear 65 drives a transmission gear 63 to rotate, which in turn drives a drive rod 61 to rotate. The drive rod 61 then drives two transmission bevel gears 62 to rotate, which in turn drives a transmission bevel gear 60 to rotate. The rotation of transmission bevel gear 60 then drives a drive screw 59 to rotate, thus enabling the membrane material traction frame 7 to move. During the movement of the membrane material traction frame 7, the membrane material end fixing frame 9 moves synchronously, facilitating the conveying of the membrane material. When the extended protrusion of the membrane material end fixing frame 9 is inserted into the fixing groove 11, the electric push rod 13 engages the buckle. Rod 14 is inserted into buckle hole 12, fixing film end holder 9 to one side of equipment cavity 5. This allows the film to be conveyed to directly below the bottom of the battery. Servo motor 57 drives transmission gear 8 58 to rotate. Transmission gear 8 58 then drives transmission gear 7 56 to rotate, which in turn drives drive rod 54. Drive rod 54 drives two transmission bevel gears 4 55 to rotate, which in turn drives transmission bevel gear 3 53 to rotate. Transmission bevel gear 3 53 then drives control screw 52 to rotate, thus causing the film pressing frame 20 to move upwards. The raised film pressing frame 20 causes the antistatic silicone block 21 to lift the film portion, allowing the film portion to contact the bottom of the battery.The film application process is achieved through the self-rebound and deformation capabilities of the anti-static silicone block 21, which facilitates better film application and improves the application effect. After film application, the servo motor 450 drives the transmission gear 451 to rotate, which in turn drives the transmission gear 49 to rotate. The transmission gear 49 then drives two drive gears 48 to rotate. The rotation of the two drive gears 48, through meshing with the rack 47, drives the entire cutting frame plate 46 to move up and down, cutting the usable portion of the film material. This ensures stable operation of the overall film application process. After film application, the electric push rod 13 drives the buckle rod 14 to disengage from the buckle hole 12, causing the coil spring 17 to lose its restraint. This causes the winding wheel 16 to rotate, continuously winding the drive rope 66. As the drive rope 66 is continuously wound up, the distance between the film material end fixing frame 9 and the film material traction frame 7 gradually decreases until they attract and connect to each other, thus restoring the film material delivery and the limiting fixation of one end of the film material.

[0052] In summary, the film material on the film roll 3 is staggered on multiple tension rollers 4, and one end of the film material passes through the film material traction frame 7 and is fixedly engaged with the film material end fixing frame 9. The film material traction frame 7 moves, which in turn drives the film material end fixing frame 9 to move synchronously, thus conveying the film material. When the extended protrusion of the film material end fixing frame 9 is inserted into the fixing groove 11, the electric push rod 13 inserts the buckle rod 14 into the buckle hole 12, fixing the film material end fixing frame 9 to one side of the equipment cavity 5. This allows the film material to be conveyed directly below the bottom of the battery. Then, the pressure frame 20 is raised, causing the antistatic silicone block 21 to lift the film material portion, allowing the film material portion to contact the bottom of the battery. The film is applied by contacting the parts of the film. The anti-static silicone block 21 has its own elasticity and deformation ability, which makes the film application better and improves the film application effect. After the film is applied, the film material is cut by the cutting component to facilitate the stable operation of the overall film application. After the film application is completed, the electric push rod 13 drives the buckle rod 14 to disengage from the buckle hole 12, so that the coil spring 17 is unrestrained and drives the winding wheel 16 to rotate, continuously winding the drive rope 66. The drive rope 66 is continuously wound up, so that the gap between the film material end fixing frame 9 and the film material traction frame 7 becomes smaller and smaller until the two are attracted and connected to each other, so that the film material is re-contained and the film material end is fixed, improving the overall operation effect and efficiency.
