When the first electric cylinder 8 drives the first moving plate 9 to move along the X-axis direction, the connecting plate 10 is synchronously moved, and the stability of the movement of the connecting plate 10 is improved by setting the slide rail 3 and the sliding block 4 in cooperation, thereby improving the accuracy of the battery film suction position (the horizontal installation and fixation of the connecting plate 10 are ensured by setting the base plate 5).

[0029] The mounting plate 11 is vertically fixed on the top of the connecting plate 10 by welding, and the mounting plate 11 and the connecting plate 10 form a "T" shaped structure. The second electric cylinder 12 is fixed on one side of the mounting plate 11, and the second moving plate 13 is fixed on the sliding part of the second electric cylinder 12 by screw fastening. The second moving plate 13 is driven by the second electric cylinder 12 to move along the Y-axis direction, thereby realizing the transfer of the battery film.

[0030] The first electric cylinder 8 and the second electric cylinder 12 are selected from commercially available ETH14-L20-350-BC-M40-C4 type electric cylinders.

[0031] The lifting module 14 is vertically fixed on the side of the second moving plate 13 away from the second electric cylinder 12, and the lifting plate 15 is fixed on the sliding part of the lifting module 14. The lifting plate 15 is driven by the lifting module 14 to perform lifting movement. As shown in Figure 3 The fixed sheet 16 is fixed on the aluminum alloy profile of the lifting module 14 by screw fastening, the first photoelectric sensor 17 and the second photoelectric sensor 18 are respectively fixed on the fixed sheet 16, and the first photoelectric sensor 17 and the second photoelectric sensor 18 are arranged above and below to detect the two limit positions of the lifting of the lifting plate 15, thereby ensuring the accuracy of the battery film suction and transfer position.

[0032] The lifting module 14 is selected from commercially available TPA-GCR-120-1605C-L50 type linear modules.

[0033] The first folding sheet 19 is fixed on the sliding part of the lifting module 14 by screw fastening, the second folding sheet 20 is integrally connected to one side of the first folding sheet 19 and extends outward, and the third folding sheet 21 is integrally connected to one side of the second folding sheet 20 close to the photoelectric sensor. When the lifting module 14 drives the lifting plate 15 to lift, the folding sheets are synchronously lifted, and the two limit positions of the lifting of the lifting plate 15 are detected by the first photoelectric sensor 17 and the second photoelectric sensor 18.

[0034] The extension plate 22 is integrally connected to the bottom of the lifting plate 15 and extends away from the second moving plate 13. The housing of the rotary motor 23 is fixed to the top of the extension plate 22 by screws. The motor shaft of the rotary motor 23 passes through the extension plate 22 and is connected to the holding assembly, thereby driving the holding assembly and the suction nozzle below to rotate, so as to complete the rotation of the battery film.

[0035] like Figure 4 , 5 As shown, the holding assembly includes an extension post 24, a first holding piece 25, a second holding piece 26, a holding groove 27, a through groove 28, a locking plate 29, a locking hole 30, a spring groove 31, and a fastening hole 32. The first holding piece 25 is integrally connected to the top of the extension post 24. The first holding piece 25 is fan-shaped, and the fan-center angle of the first holding piece 25 is 180°. The second holding piece 26 cooperates with the first holding piece 25. The second holding piece 26 is also fan-shaped, and the fan-center angle of the second holding piece 26 is also 180° (the second holding piece 26 is not fixed to the extension post 24).

[0036] The locking plate 29 is fixed to the top of the extension column 24 by screws. The locking hole 30 and the spring groove 31 vertically penetrate the locking plate 29 and are interconnected. After the locking plate 29 is fixed to the top of the extension column 24, the first holding piece 25 and the second holding piece 26 are located in the locking hole 30 of the locking plate 29, and a holding groove 27 is formed on the opposite side of the first holding piece 25 and the second holding piece 26 for holding the motor shaft of the rotary motor 23.

[0037] The fastening hole 32 is provided on the locking plate 29. The fastening bolt passes through the fastening hole 32. By tightening the fastening bolt, the gap in the spring groove 31 gradually decreases, thereby clamping the second holding piece 26 inward, thus holding the motor shaft of the rotary motor 23. When the rotary motor 23 rotates, it drives the extension column 24 to rotate synchronously.

[0038] In actual installation, first fix the locking plate 29 to the top of the extension column 24, insert the second holding piece 26 into the locking hole 30 of the locking plate 29, and then pass the motor shaft of the rotary motor 23 through the holding groove 27 formed by the first holding piece 25 and the second holding piece 26. Insert the fastening bolt into the fastening hole 32 on the side wall of the locking plate 29, and then tighten the fastening bolt. At this time, the gap of the spring groove 31 gradually becomes smaller, thereby clamping the second holding piece 26 inward, thus holding the motor shaft of the rotary motor 23. When the rotary motor 23 rotates, it drives the extension column 24 to rotate synchronously.

[0039] The rotation of the rotary motor 23 is transmitted to the suction nozzle below by a gripping assembly, thereby driving the gripping assembly and the suction nozzle to rotate synchronously to complete the rotation of the battery film. Avoid using fastening screws on the motor shaft of the rotary motor 23 to fix the suction nozzle, as this could damage the rotary motor 23 and extend its service life.

[0040] The through slot 28 extends through the extension column 24. The through slot 28 is designed to reduce the weight of the extension column 24 and save costs.

[0041] The suction nozzle is fixed to the bottom of the extension column 24 and is used to pick up the battery film, such as... Figure 6 , 7 As shown, the suction nozzle includes a fixing plate 33, a fixing groove 34, a fixing block 35, a first air passage 36, a second air passage 37, a connecting air passage 38, a side mounting hole 39, a suction rod, a side suction pipe 45, and a side suction air passage 46. The fixing groove 34 is formed on both sides of the fixing plate 33. Fastening bolts pass through the fixing groove 34 and the extension post 24, and a fastening nut is used on the other side to complete the fixing of the fixing plate 33 and the extension post 24.

[0042] The fixing block 35 is integrally connected to the bottom of the fixing plate 33. The first air passage 36 and the second air passage 37 are formed inside the fixing block 35. The connecting air passage 38 is used to connect the first air passage 36 and the second air passage 37. The side mounting hole 39 is formed in the side wall of the fixing block 35. The side suction pipe 45 is fixed in the side mounting hole 39 by a threaded connection (specifically, the side mounting hole 39 has an internal thread, and the side of the side suction pipe 45 near the side mounting hole 39 has an external thread that mates with it). The side suction air passage 46 horizontally passes through the side suction pipe 45 and is connected to the first air passage 36. The end of the side suction pipe 45 away from the fixing block 35 is connected to an air pump through a hose. The air pump draws a vacuum into the first air passage 36 and the second air passage 37, thereby sucking up the battery film.

[0043] There are two suction rods, installed in the first air passage 36 and the second air passage 37 respectively. By using two suction rods, the suction is more secure when picking up the battery film, preventing the film from falling off during transfer. The suction rods include a main suction tube 40, a secondary suction tube 41, a main suction channel 42, and a secondary suction channel 43. The inner walls of the bottom of the first air passage 36 and the second air passage 37 are provided with internal threads, and the outer wall of the top of the main suction tube 40 is provided with matching external threads. Therefore, the main suction tube 40 can be screwed onto the first air passage 36 and the second air passage 37, and its height can be adjusted to ensure that the two suction rods are in the same plane.

[0044] The auxiliary suction tube 41 is integrally connected to the bottom of the main suction tube 40. The main air intake channel 42 vertically penetrates the main suction tube 40 and is connected to the first air passage 36. The auxiliary air intake channel 43 vertically penetrates the auxiliary suction tube 41 and is connected to the main air intake channel 42, thereby allowing the auxiliary suction tube 41 to draw in the battery film.

[0045] like Figure 7 As shown, the diameter of the bottom of the auxiliary suction tube 41 gradually decreases from top to bottom, making it more secure and reliable when picking up the battery film.

[0046] The automatic film-applying mechanism for batteries of this invention operates on the following principle:

[0047] The first electric cylinder 8 drives the first moving plate 9 to move along the X-axis, the second electric cylinder 12 drives the second moving plate 13 to move along the Y-axis, and the lifting module 14 drives the lifting plate 15 to descend along the Z-axis. Finally, the suction nozzle picks up the battery film and transfers it to the battery film application area. The rotary motor 23 drives it to rotate to a suitable angle and apply it to the battery surface.
