[0041] In the embodiment, the hinge between the cylinder body 410 and the base frame 100 and the hinge between the piston rod 420 and the carrying beam 200 are staggered in the first direction and the second direction, and the cylinder 400 is configured to drive the carrying beam 200 to overturn by a preset angle upward when the piston rod 420 thereof extends outward, thereby switching from the working position to the overturned position. The overturning angle of the carrying beam 200 can be determined according to actual use, and preferably, the overturning angle is an acute angle or a right angle, and the range of the overturning angle is 60-90°.

[0042] Further, the base frame 100 is provided with a limiting unit 500 acting on the carrying beam 200 to keep the carrying beam 200 in the working position. The limiting unit 500 can be arranged on the frame body 120 or the support arm 110. In an embodiment, the limiting unit 500 is fixedly arranged on the support arm 110, and the following description is based on the limiting unit 500 being fixedly arranged on the support arm 110.

[0043] The limiting unit 500 can be a block fixedly arranged on the support arm 110 or an oil pressure buffer 520 arranged on the support arm 110. In an embodiment, as shown in Figure 6 The limiting unit 500 includes a connecting seat 510 fixedly arranged on the support arm 110, an oil pressure buffer 520 arranged on the connecting seat 510, and a limiting sleeve 530 arranged on a fixed part of the oil pressure buffer 520.

That is, the limiting sleeve 530 limits the working position of the carrying beam 200, and the oil pressure buffer 520 plays a role of buffering force.

[0044] As shown in Figure 3 The first mounting seat 430 includes a movable seat 431 arranged on the frame body 120 of the base frame 100, a fixed block 432 fixedly arranged on the frame body 120 and located above the movable seat 431, a first screw 433 fixedly connected with the movable seat 431, and a first nut 434 arranged on the first screw 433. The cylinder body 410 is hingedly connected with the movable seat 431, the fixed block 432 is provided with a threaded hole matched with the first screw 433, the first screw 433 penetrates through the fixed block 432 along the second direction (up-down direction) through the threaded hole, and the first nut 434 is located below the fixed block 432.

[0045] The base frame 100 is provided with a first slot extending along the second direction on the frame body 120, and the movable seat 431 is adjustably arranged on the frame body 120 of the base frame 100 through a second bolt (not shown in the figure) matched with the first slot. In an embodiment, the frame body 120 is made of a profile, which is provided with the above-mentioned first slot. Of course, the frame body 120 can also be made of other materials, including but not limited to the profile. Preferably, the frame body 120 and the bearing beam 200 are both profiles.

[0046] The first bolt 433 and the first nut 434 can be used to finely adjust the position of the movable seat 431 in the second direction. Specifically, when it is necessary to adjust the position of the movable seat 431 in the second direction, the second bolt is loosened first, then the first nut 434 is loosened, and after adjusting the position of the movable seat 431 through the first bolt 433, the first nut 434 and the second bolt are tightened respectively. In the whole adjustment process, no component is separated from the frame body 120, and the adjustment is convenient.

[0047] As shown in Figure 8 and Figure 9 , the suction cup unit 300 includes a plate body 310 arranged at the bottom of the bearing beam 200 and a suction nozzle 320 arranged on the plate body 310. The plate body 310 is provided with a sliding groove 311 extending along the first direction, and the suction nozzle 320 is slidingly arranged in the sliding groove 311. Thus, the position of the suction nozzle 320 can be more conveniently adjusted, thereby facilitating the suction nozzle 320 to more stably adsorb the battery piece 700. When the bearing beam 200 is in the working position, the plate body 310 is in a horizontal state, and the suction nozzle 320 is distributed substantially perpendicular to the plate body 310. It should be noted that in the present specification, "substantially" can be understood as close to, approximate, or within a predetermined range of the target value.

[0048] The bottom end surface of the bearing beam 200 is provided with a second slot (not shown in the figure) extending along the direction of the rotation axis of the bearing beam 200. The plate body 310 is fastened to the bottom end surface of the bearing beam 200 through a third bolt (not shown in the figure) matched with the second slot, and the plate body 310 has a first through hole 313 for the third bolt to pass through.

[0049] In order to facilitate accurate installation of the plate body 310 on the bottom end surface of the bearing beam 200, the plate body 310 is further provided with a bent portion 312. The bent portion 312 is in a sheet shape and is distributed substantially perpendicular to the plate body 310. The bent portion 312 is arranged with the same width as the second slot and is at least partially inserted into the second slot, which is used for rough positioning of the plate body 310 during installation.

[0050] As shown in Figure 9As shown, the first gasket 321, the second gasket 322 and the second elastic member 323 are sequentially sleeved on the suction nozzle 320 from bottom to top. The second elastic member 323 directly acts on the second gasket 322, so that the first gasket 321 abuts against the bottom end surface of the plate body 310, and the second gasket 322 abuts against the top end surface of the plate body 310. When the suction nozzle 320 sucks the battery piece 700, the second elastic member 323 can also play a buffering role, avoiding damage to the battery piece 700 caused by the suction action of the suction nozzle 320.

[0051] Further, as shown in Figure 4 The two side ends of the carrying beam 200 are provided with the pressing block units 600, and the plurality of suction disc units 300 are located between the pressing block units 600.

As shown in Figure 8 Sixteen welding bands 800 are arranged on the battery piece 700, and correspondingly, sixteen pressing blocks 620 are arranged on the pressing block seat 610. The movement of each pressing block 620 is independent of each other. The pressing blocks 620 are used to press the end D of the welding band 800 which is exposed outside the battery piece 700 on both sides.

[0054] The pressing block seat 610 is fastened to the bottom end surface of the carrying beam 200 by fourth bolts (not shown in the figure), and the fourth bolts are matched with the second grooves. The position of the pressing block seat 610 on the carrying beam 200 is adjustable. The fourth bolts can be loosened, and then the position of the pressing block seat 610 relative to the end D of the welding band 800 is adjusted.

[0055] Further, as shown in Figure 10 and Figure 11As shown, the pressing block 620 is arranged on the pressing block seat 610 through the guide column 640, and the pressing block seat 610 is provided with a second through hole (not shown in the figure) for the guide column 640 to pass through in the second direction.
