[0042] Embodiment 2: The present invention will be further described below in conjunction with embodiment 1.

[0043] In order to solve the technical problems that after arriving at the transfer location, the materials need to be manually transported to the designated location, and the materials need to be frequently loaded and unloaded, the operation is cumbersome, and there is a lack of effective tools, the transportation efficiency is low, and the progress of the entire line sequence test is affected, such as Figure 7 - Fig.12 As shown, the following preferred technical solutions are provided:
