[0054] Furthermore, the transfer module is composed of a first transfer module E17 and a second transfer module E18; and the first transfer module E17 includes: a horizontally arranged transfer workbench E19; a transfer linear module E20 arranged below the transfer workbench E19; and a second lifting cylinder E21 is arranged on the reciprocating slider of the linear module; and the piston rod of the second lifting cylinder E21 is connected to a transfer push plate E22; and the second transfer module E18 has the same structure as the first transfer module E17; through the second lifting cylinder E21, the transfer push plate E22 is connected to the transfer push plate E22; The lowering cylinder E21 drives the transfer pushing plate E22 to abut the full material tray E12; and the transfer linear module E20 of the first transfer module E17 drives the transfer pushing plate E22 of the first transfer module E17 to move toward the second transfer module E18, and the transfer linear module E20 of the second transfer module E18 drives the transfer pushing plate E22 of the second transfer module E18 to move toward the full material tray stacking module E2; thereby synchronously driving the full material tray E12 to move toward the full material tray stacking module E2.

[0055] Specifically, the horizontally arranged transfer workbench E19 is used to carry and transfer the full material tray E12; the transfer linear module E20 is located below the transfer workbench E19 and is responsible for driving the transfer push plate E22 to move in the horizontal direction; the second lifting cylinder E21 is arranged on the reciprocating slider and is used to control the lifting and lowering of the transfer push plate E22; the transfer push plate E22 is connected to the piston rod of the second lifting cylinder E21 and is used to push the full material tray E12; the second transfer module E18 has the same structure and function as the first transfer module E17;

[0059] When the first layer of empty trays E11 moves from the first conveying roller device E5, the baffle plate E29 plays an auxiliary limiting role on the empty tray E11 above, ensuring that the empty tray E11 above will not deviate; when the empty tray E11 rolls to the position of the baffle module, the avoidance groove E30 provides an avoidance space for the first layer of empty trays E11, ensuring that the trays can pass smoothly without being damaged or offset due to collision with other structures.

[0060] Furthermore, a limiting mechanism E23 is provided on one side of the first transfer module E17; and the limiting mechanism E23 includes a horizontally arranged limiting cylinder E24; and the piston rod of the limiting cylinder E24 is connected to the limiting block E25; and the limiting block E25 is formed with a V-shaped groove E26; when the empty tray E11 reaches the battery cell loading station E6, the limiting cylinder E24 drives the limiting block E25 to extend out to abut against the empty tray E11 for limiting.
