When the tray 41 is located between the first stopping assembly 44 and the second stopping assembly 45, the second supporting platform 42 is lifted, and the tray 41 just falls on the second supporting platform 42, so that the second limiting column 423 is matched with the second limiting hole 411 to limit the tray 41 to slide on the second supporting platform 42.

In an embodiment of the present invention, referring to fig. 12, the first stopping assembly 44 includes a roller 441, a mounting seat 442 and a lifting pusher 443, the roller 441 is mounted on the mounting seat 442, the mounting seat 442 is mounted on the lifting pusher 443, the lifting pusher 443 is mounted on the frame 1, the lifting pusher 443 drives the mounting seat 442 to move up and down, and the mounting seat 442 drives the roller 441 to move up and down. The roller 441 is adopted to stop the tray 41, so that the impact on the tray 41 and the transmission mechanism is reduced, and the equipment is prevented from being damaged. Moreover, the roller 441 is adopted to reduce the resistance of the tray 41 during lifting, reduce the distance between the first stopping assembly 44 and the second stopping assembly 45, and improve the position accuracy of the tray 41. Alternatively, the lifting pusher 443 is a cylinder or the like, and the cylinder is cheap and cost-saving.

Optionally, referring to fig. 9 and fig. 10, a second sensor 46 is disposed on the rack 1, the second sensor 46 is configured to sense a position of the pouch battery 71, a through hole is formed in the second support platform 42, the position of the through hole corresponds to a position of the second sensor 46, and when the pouch battery 71 conveyed by the conveying mechanism passes through the upper portion of the assembly platform 4, the second sensor 46 can sense the pouch battery 71, so as to control the assembly joint 72 of the pouch battery 71 on the tray 41.

Optionally, referring to fig. 9, the second stopping assembly 45 has the same structure as the first stopping assembly 44, and the first stopping assembly 44 is disposed opposite to the second stopping assembly 45, which is beneficial to reducing the equipment cost.

Alternatively, referring to fig. 11 and 12, two positioning grooves 412 are respectively disposed at two ends of the tray 41, and the two positioning grooves 412 are respectively matched with the corresponding rollers 441, so as to improve the position accuracy of the tray 41.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
