[0037] like Figures 1 to 4 As shown, in this embodiment, the upper track assembly 20 includes a first support frame 21, a first conveying track 22, two groups of first blocking members 23 and two groups of first lifting assemblies 24.

[0038] Two groups of first lifting assemblies 24 are arranged on the first conveying track 22, and two groups of first blocking members 23 are respectively arranged at one end of the two groups of first lifting assemblies 24 along the conveying direction of the first conveying track 22.

When the tray 11 reaches the positioning height at the transmission seat 45, the transmission seat 45 descends to transfer the empty tray 11 to the lower track assembly 30.

[0046] In this embodiment, the first conveying track 22, the second conveying track 32 and the third conveying track 452 all include a synchronous belt track assembly 221, a transmission shaft 222 drivingly connected to the synchronous belt track assembly 221, and a driving motor 223 axially connected to the transmission shaft 222. The driving motor 223 drives the synchronous belt track assembly 221 to rotate, thereby driving the material tray 11 to move.

[0047] Example 2

[0048] The difference between Example 2 and Example 1 is that:
