[0031] The transfer mechanism 200 includes a first adsorption device 230 and a linear driving device 210. The first adsorption device 230 is slidably connected to the linear driving device 210. A gap 236 is left in the horizontal direction at the center of the lower half of the first adsorption device 230. The gap 236 is used for the folding plate 340 to penetrate the first adsorption device 230 or the first adsorption device 230 to be penetrated by the folding plate 340. The first adsorption device 230 can move towards the folding plate 340, or the folding plate 340 can move towards the first adsorption device 230, or the first adsorption device 230 and the folding plate 340 can move towards each other.

[0032] The folding plate 340, the carrying mechanism 100, and the first adsorption device 230 are in the same vertical plane.

[0033] During use, the lithium battery 500 to be folded is placed on the carrying mechanism 100; then the first adsorption device 230 adsorbs the lithium battery 500 on the carrying mechanism 100, and the linear driving device 210 transfers the lithium battery 500 above the folding mechanism 300; the transfer mechanism 200 and / or the folding mechanism 300 are moved vertically, so that the folding plate 340 presses against the pole piece between the two lithium batteries 500 and enters the gap 236 to complete the folding of the lithium battery 500, and then the lithium battery 500 is taken away to leave a folding position for the next lithium battery 500 waiting for folding in the assembly line.

[0035] The first cylinder 140 is connected to a third vacuum pump. During use, first inflate the first cylinder 140 to make the first bearing frame 170 and the second bearing frame 180 move longitudinally in opposite directions to each other, causing the upper ends of the first bearing frame 170 and the second bearing frame 180 to rotate away from the upper support plate 160. After the lithium battery 500 is placed on the upper support plate 160, deflate the first cylinder 140. The other ends of the rotating parts of the upper ends of the first bearing frame 170 and the second bearing frame 180 are lapped on the upper support plate 160 from bottom to top to wrap the pole pieces at both ends of the lithium battery 500 around the lithium battery 500.

[0036] As Figure 1 , Figure 2 , Figure 4 As shown in the figure, as a further solution of the present utility model: The first bearing frame 170 includes an L-shaped bearing plate 171, a mounting shaft 173, two mounting sleeves 174, two rocker arms 172, a first roller 175, and a second roller 176; A through hole is provided at the top end of the L-shaped bearing plate 171. The mounting shaft 173, two mounting sleeves 174, and two rocker arms 172 are installed together. The rocker arms 172 are rotatably connected to the L-shaped bearing plate 171. The other ends of the two rocker arms 172 are installed with second rollers 176, and both ends of the first roller 175 are respectively installed in the middle of the two rocker arms 172.

[0037] The structure of the second carrier 180 is exactly the same as that of the first carrier 170, and it is axially symmetrically arranged with respect to the vertical center line of the upper support plate 160.

[0039] During use, the first vacuum pump and the second vacuum pump are simultaneously deflated or inflated to suck the lithium battery 500 to be folded on the upper support plate 160, and then the first adsorption device 230 is moved above the folding mechanism 300. When the folding plate 340 enters or is entered into the gap 236, the first adsorption device 230 starts to be inflated, so that the lithium battery 500 is separated from the first adsorption device 230 during the folding process of the lithium battery 500, and finally the lithium battery 500 is folded.

[0040] As Figure 1 , Figure 3 shown, as a further solution of the present invention: a third roller 234 is arranged at the inner side of the lower end of the first adsorbent 232, and a fourth roller 235 is arranged at the inner side of the lower end of the second adsorbent 233.

[0043] The second cylinder 220 is slidably connected to the linear drive device 210, the second cylinder 220 is fixedly connected to the first adsorption device 230 by bolts, and the first adsorption device 230 is transferred above the folding mechanism 300 through the second cylinder 220, and then the second cylinder 220 is controlled to move the first adsorption device 230 downward, so that the folding plate 340 enters the gap 236 to complete the folding of the lithium battery 500.

[0044] As shown in Figure 1 Figure , as a further solution of the present utility model: a third cylinder 330 is further provided between the first support seat 310 and the folding plate 340, and the third cylinder 330 is used to move the folding plate 340 up and down reciprocally.

[0045] The third cylinder 330 is connected to the first support seat 310 through a third cylinder mounting plate 320, the third cylinder 330 is installed in the vertical direction, and the third cylinder 330 can control the folding plate 340 to move up and down. When the first adsorption device 230 is moved above the folding plate 340, the third cylinder 330 can control the folding plate 340 to move upward, so that the folding plate 340 enters the gap 236 to fold the lithium battery 500. The third cylinder 330 and the second cylinder 220 can also be controlled simultaneously to make the folding plate 340 and the first adsorption device 230 move towards each other, so that the folding plate 340 enters the gap 236 to fold the lithium battery 500.

[0046] As shown in Figure 1 , Figure 2 Figure , as a further solution of the present utility model: it further includes two linearly arranged linear guide rails 400, and the second support seat 110 is slidably connected to the two linear guide rails 400.

[0047] It should be noted that the specific figure numbers in the original text are replaced with [ID=X] in the translation for the purpose of generality. You may need to substitute the actual figure numbers according to the specific situation.The second support base 110 includes a support base main body connecting plate 111, a support base main body 114, a fourth cylinder 113, a first air nozzle 112, a fifth cylinder 115, and a second air nozzle 116.

The support base main body connecting plate 111 is fixedly mounted on one end face of the support base main body 114 by bolts. The fourth cylinder 113 and the fifth cylinder 115 are respectively fixedly mounted at both ends under the support base main body 114 by bolts and are respectively slidably connected to the two linear guide rails 400. The first air nozzle 112 and the second air nozzle 116 are respectively mounted on the fourth cylinder 113 and the fifth cylinder 115.

[0048] The transfer mechanism 200 further includes a second adsorption device 240. A transport mechanism 600 is further mounted on the two linear guide rails 400. The transport mechanism 600 is mounted at one end of the second support 110 away from the folding mechanism 300. During use, first, the second adsorption device 240 adsorbs the lithium battery 500 to be folded on the transport mechanism 600, and then the transport mechanism 600 and the carrying mechanism 100 are simultaneously operated to move both in a direction away from the folding mechanism 300, so as to transfer the upper support plate 160 to directly below the second adsorption device 240, and the lithium battery 500 adsorbed by the second adsorption device 240 is placed on the upper support plate 160. Then, the carrying mechanism 100 is moved to the original position to wait for the first adsorption device 230 to adsorb the lithium battery 500 on the upper support plate 160. After the lithium battery 500 is folded, the first adsorption device 230 is transferred to the original position, and the transport mechanism 600 and the carrying mechanism 100 are simultaneously operated again to move both in a direction away from the folding mechanism 300, and the operation is repeated.

[0049] As Figure 1 shown, as a further solution of the present invention: the folding mechanism 300 is slidably connected to the two linear guide rails 400.

[0050] Slidingly connecting the folding mechanism 300 to the two linear guide rails 400 can bring the folding mechanism 300 closer to the carrying mechanism 100, which is beneficial to solving the problem of insufficient stroke of the first adsorption device 230.
