[0042] In this embodiment, the transfer mechanism 1 completes the loading and unloading of the material preparation tray 5 on the same side, which occupies little space and has a compact structure.

[0043] In one embodiment, such as Figure 1 , Figure 9 as well as Figure 8 As shown, the automatic button battery preparation equipment also includes a buffer mechanism 6 and a conveying mechanism 7; The buffer mechanism 6 includes a buffer seat 61, a buffer moving seat 62, a first buffer plate 63 and a second buffer plate 64.

[0044] The buffer moving seat 62 can drive the second buffer plate 64 on it to move, so that the conveying mechanism 7 can transfer the material trays 5 one by one from the buffer moving seat 62.

The conveying mechanism 7 transfers the material trays 5 on the second buffer plate one by one into the storage tray box 83, and the detection mechanism is used to detect whether the material trays 5 located in the storage tray box 83 are empty. When the detection mechanism detects that the material preparation tray 5 is not empty, the flipping drive 82 drives the storage tray box 83 to flip, so that the material preparation tray 5 in the storage tray box 83 falls into the receiving tray box 84. When the detection mechanism detects that the material preparation tray 5 is empty, the handling mechanism 7 transfers the empty material preparation tray 5 in the storage tray box 83 to the second conveyor belt assembly 12.

[0048] The flipping drive component 82 includes, but is not limited to, a motor, and the detection mechanism includes, but is not limited to, a camera.

[0049] Specifically, the conveying mechanism 7 first adsorbs the preparation trays 5 one by one from the second buffer plate 64 and transfers them into the storage tray box 83. The detection mechanism detects whether the preparation trays 5 in the storage tray box 83 are empty. When the detection mechanism detects that the preparation trays 5 are not empty, the flipping drive 82 drives the storage tray box 83 to flip, so that the opening of the storage tray box 83 faces the opposite direction and the preparation trays 5 fall into the receiving tray box 84 below. When the detection mechanism detects that the preparation trays 5 are empty, the conveying mechanism 7 then picks up the empty preparation trays 5 from the storage tray box 83 and transfers them to the second conveyor belt assembly 12.

[0050] In this embodiment, the design of the conveying mechanism 7 and the flipping mechanism 8 ensures that the material tray 5 fed to the transfer mechanism 1 is an empty tray.
