Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1

[0037] Among them Figure 5-7 As shown, the negative pressure film suction mechanism 2 includes a suction cup 201 and a negative pressure suction pipe 202. A connecting hole 203 is opened inside the suction cup 201. The connecting hole 203 is fixedly connected to the negative pressure suction pipe 202. The negative pressure suction pipe 202 is connected to a negative pressure pump through a hose; the movable adjustment seat 3 includes a rotating column 301 and a steering cylinder 302.

[0038] Among them Figure 6-7 As shown, the suction cup 201 is made of hard plastic; a soft rubber pad 204 is fixed to the outer edge of the suction cup 201; the rubber pad 204 is used to squeeze the gap between the suction cup 201 and the film head 501 to achieve a sealing effect. Under the suction force of the negative pressure pump, the sealing effect is achieved and sufficient suction is guaranteed to adsorb the film head 501 on the suction cup 201.

[0039] Embodiment 2

[0040] A more preferred technical solution based on the first embodiment is as follows: Fig.10As shown, a support net 205 is fixedly installed on the inner wall of the suction cup 201; the support net 205 is conducive to the film head 501 remaining on the support net 205 after being adsorbed by the suction cup 201, and can greatly avoid the film head 501 being adsorbed and pulled to the inner wall of the suction cup 201, which causes a large gap to appear after the edge of the film head 501 is adsorbed to the inside of the suction cup 201, thereby destroying the sealing effect between the suction cup 201 and the film head 501; thereby ensuring the stability of the adsorption effect.

[0041] Among them Fig.10 As shown, at least one micro suction cup 206 is fixedly installed on the support net 205, and the inner end of the micro suction cup 206 is fixedly connected to a negative pressure connecting pipe 207, the side surface of the negative pressure connecting pipe 207 is gap-matched with the inner wall of the negative pressure suction pipe 202, and the inner end of the negative pressure connecting pipe 207 is connected to the inside of the negative pressure suction pipe 202; the support net 205 can also provide a supporting and fixing effect for the micro suction cup 206; the micro suction cup 206 and the suction cup 201 play a double-layer role in ensuring the adsorption effect; the negative pressure film suction mechanism 2 can maintain the double-layer protection effect of adsorbing the film head 501.

[0042] Embodiment 3

[0043] A more preferred technical solution based on the second embodiment is as follows: Fig.11 As shown, the negative pressure suction pipe 202 is slidably matched with the movable adjustment seat 3, and a spring 208 is fixedly connected between the back of the suction cup 201 and the movable adjustment seat 3, and the negative pressure suction pipe 202 is respectively fixed with a limit ring A209 and a limit ring B210 on both sides of the movable adjustment seat 3; the negative pressure suction pipe 202 only needs to control the movement displacement of the negative pressure film suction mechanism 2 by the movable adjustment seat 3, so that the spring 208 can provide the suction cup 201 with a stable and elastic extrusion force within an appropriate range, thereby avoiding excessive or insufficient extrusion.

[0044] Embodiment 4

[0045] A more preferred technical solution based on the third embodiment is as follows: Figure 12-13As shown, the support 303 includes an articulated seat 304 and a connecting rod 305, the end of the articulated seat 304 is hinged with the connecting rod 305, the articulated seat 304 is fixed with a limit baffle 306 on the outside of the hinge, and the articulated seat 304 is also equipped with a torsion spring 308 at the hinge; the articulated seat 304 is also fixed with a limit column 307 on the inside of the hinge; the limit baffle 306 is used to ensure that the articulated seat 304 directly transmits the force to the negative pressure film suction mechanism 2 through the connecting rod 305, so that the negative pressure film suction mechanism 2 squeezes and fits the film head 501; and the function of the articulated relationship between the articulated seat 304 and the connecting rod 305 is that when After the film head 501 on the battery box 5 is pulled away from the starting end surface, in order to ensure that the film 502 will not be broken due to the large displacement of the film head 501, and to ensure the subsequent operation effect of detaching the film 502 from the battery box 5 due to the adsorption of the film head 501; therefore, when the support 303 is reset, the connecting rod 305 will rotate with the hinge seat 304 to reduce the displacement of the film head 501, and the torsion spring 308 controls the elastic pulling force of the connecting rod 305 and the negative pressure film suction mechanism 2 on the film 502, thereby achieving a protective effect on the pulling between the film 502 and the film head 501 to avoid being broken.
