Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0026] The present application will be described in detail below in conjunction with the drawings and specific embodiments. Embodiment

[0027] ReferenceFigures 1-2 , a PTC heating film laminating tooling device, comprising: an equipment cabinet 1, a processing table 11 is arranged on the top of the equipment cabinet 1, four positioning frames 12 are fixedly connected to the top of the processing table 11, and a groove 13 is formed in the top of the equipment cabinet 1; a laminating assembly is arranged on the equipment cabinet 1 and is used for laminating the PTC heating film on the inner wall of the battery case, and a feeding assembly is arranged inside the equipment cabinet 1 and is used for conveying the PTC heating film.

[0028] When laminating the PTC heating film on the inner wall of the battery case, the mounting holes connected to the inner wall of the battery case are sleeved in the four positioning frames 12 to position the battery case, and at the same time, the movement of the battery case can be avoided. A stack of PTC heating films is placed on the feeding assembly, and the PTC heating film is conveyed to a designated position by the feeding assembly. The topmost PTC heating film is sucked up by the laminating assembly and moved to the battery case, and the PTC heating film is laminated on the battery case. Embodiment

[0029] Reference Figures 3-6 , on the basis of Embodiment 1, the laminating assembly includes: a mounting plate 2, guide rods 21, a moving plate 22, rails 23 and suction cups 24. A mounting plate 2 is arranged above the equipment cabinet 1. Four guide rods 21 are respectively slidably connected to the mounting plate 2. The bottom ends of the four guide rods 21 are fixedly connected to a moving plate 22. Two rails 23 are arranged below the moving plate 22. Two suction cups 24 are respectively arranged on the two rails 23. A pressing plate 25 is arranged at the bottom of the rail 23. Moving holes 26 through which the four suction cups 24 can pass are respectively formed in the pressing plate 25. Mounting rods 27 are respectively fixedly connected to the four corners of the bottom of the moving plate 22. Springs 28 are sleeved on the outer parts of the mounting rods 27. A connecting plate 29 is slidably connected to the outer parts of the four mounting rods 27. The bottom ends of the four mounting rods 27 are detachably connected to the pressing plate 25. Two vertical grooves 210 are respectively formed in the connecting plate 29. Four connecting rods 211 are fixedly connected to the top of the rail 23. The top ends of the four connecting rods 211 are fixedly connected to a bottom plate 212. Two screw rods 213 are fixedly connected to the top of the bottom plate 212. The top ends of the two screw rods 213 respectively penetrate through the two vertical grooves 210 and extend to the outside, and a tightening nut a214 is threadedly connected to the extended end of the screw rod 213. Transverse grooves 215 are respectively formed in the two rails 23. Threaded pipes 216 are fixedly connected to the bottom ends of the suction cups 24. The top ends of the threaded pipes 216 respectively penetrate through the transverse grooves 215 and extend to the outside, and a tightening nut b217 is threadedly connected to the extended end of the threaded pipe 216.

[0030] Among them, two pairs of vertical rods 4 are fixedly connected to the top of the equipment cabinet 1. A linear guide rail 41 is fixedly installed between the top ends of a pair of vertical rods 4. An installation frame 42 is connected between the two linear guide rails 41. A pneumatic push rod 43 is fixedly installed on the top of the installation frame 42. The bottom end of the pneumatic push rod 43 is connected to the top of the mounting plate 2.

[0031] When attaching the PTC heating film, the two linear guide rails 41 start to drive the mounting frame 42 to move above the groove 13. Subsequently, the pneumatic push rod 43 starts to push the moving plate 22 to move downward. When the moving plate 22 moves, it will drive the guide rod 21 to move along the holes of the mounting plate 2, thereby restricting the moving direction of the moving plate 22 and causing the suction cup 24 to move downward to contact the topmost PTC heating film. Subsequently, the suction cup 24 starts to suck the PTC heating film. Then, the pneumatic push rod 43 retracts, driving the mounting plate 2 to move upward and driving the mounting frame 42 to move above the processing table 11 through the two linear guide rails 41. Then, the pneumatic push rod 43 ejects again, pushing the moving plate 22 to move downward, causing the suction cup 24 to move downward with the PTC heating film sucked thereon, so that the PTC heating film is attached to the top of the battery housing. Subsequently, the suction cup 24 releases the PTC heating film, and the pneumatic push rod 43 continues to push downward, causing the suction cup 24 to press the PTC heating film. Since the suction cup 24 cannot move, affected by the reaction force, the threaded tube 216 pushes the track 23 to move upward. The track 23 pushes the bottom plate 212 to move upward through the connecting rod 211. The bottom plate 212 pushes the connecting plate 29 to move upward. When the connecting plate 29 moves upward, it compresses the spring 28, causing the spring 28 to contract and store energy. At the same time, when the moving plate 22 moves, it pushes the pressing plate 25 to move downward through the mounting rod 27, causing the pressing plate 25 to contact the PTC heating film and applying pressure to the PTC heating film through the pressing plate 25, so that the PTC heating film is adhered to the battery housing. Then, the pneumatic push rod 43 retracts, driving the moving plate 22 to move upward. The moving plate 22 drives the pressing plate 25 to move upward through the mounting rod 27. The moving hole 26 on the pressing plate 25 moves along the outside of the suction cup 24. The pressing plate 25 contacts the bottom of the track 23 and pushes the track 23 to move upward, driving the suction cup 24 to move upward. The suction cup 24 is separated from the PTC heating film. At this time, the spring 28 releases its elasticity, and the spring 28 pushes the connecting plate 29 to move downward, causing the suction cup 24 to return to its initial position, thereby completing the attachment of the PTC heating film to the battery housing.

[0032] When it is necessary to adjust the position of the suction cup 24, loosen the fastening nut b217 to release the restriction on the threaded tube 216. Then move the threaded tube 216 along the inside of the transverse groove 215 to adjust the position of the suction cup 24. After the adjustment is completed, tighten the fastening nut b217 to clamp the track 23 through the suction cup 24 and the fastening nut b217, thereby fixing the position of the suction cup 24. Furthermore, the suction cup 24 can be adjusted horizontally. Loosen the fastening nut a214 to release the restriction on the screw rod 213. Then move the track 23 along the inside of the vertical groove 210. After the position of the track 23 is adjusted, then tighten the fastening nut a214 to clamp the connecting plate 29 through the fastening nut a214 and the bottom plate 212, thereby fixing the screw rod 213. Furthermore, the position of the suction cup 24 can be adjusted vertically, so that PTC heating films of different sizes can be sucked and the processing table 11 can be replaced to adapt to battery outer shell plates of different models. Embodiment

[0033] Reference Figure 7 , on the basis of Embodiment 1, the feeding assembly includes: a square tube 3, an electric push rod 31, a lifting plate 32, a placing table 33, through holes 34 and positioning rods 35. The bottom of the groove 13 is fixedly connected with the square tube 3. The inner bottom of the square tube 3 is fixedly installed with the electric push rod 31. The top of the electric push rod 31 is fixedly installed with the lifting plate 32. The top of the lifting plate 32 is fixedly installed with the placing table 33. Four through holes 34 are respectively formed in the lifting plate 32 and the placing table 33. Four positioning rods 35 are respectively fixedly installed at the inner bottom of the square tube 3. The tops of the four positioning rods 35 respectively penetrate through the four through holes 34 and extend to the outside.

[0034] When pasting the PTC heating film, stack the PTC heating films into a pile, and then place the stacked PTC heating films on the placing table 33. When placing, pass the positioning holes on the PTC heating film through the positioning rods 35 to position the PTC heating film and prevent it from moving randomly. As the PTC heating film is continuously sucked up, the electric push rod 31 pushes the lifting plate 32 to move upward. When the lifting plate 32 moves, it pushes the placing table 33 and the stacked PTC heating films to move upward to feed the PTC heating film. When replacing different PTC heating films, disassemble the lifting plate 32, the placing table 33 and the positioning rods 35, select the lifting plate 32 and the placing table 33 adapted to the PTC heating film, align the through holes 34 on the lifting plate 32 and the placing table 33 with the positioning holes on the PTC heating film, and then align the positioning rods 35 with the through holes 34 and install them at the inner bottom of the square tube 3.
