Description

Technical Field

[0001] This utility model relates to the field of workpiece transfer technology, specifically an automatic pallet loading and unloading device. Background Technology

[0002] In consumer electronics products, SMT technology is usually required to set various SMT electronic components on flexible circuit boards. After the electronic components are assembled on the flexible board, the assembled flexible board is visually inspected to determine whether the appearance of the flexible board is qualified, and unqualified flexible boards (i.e. defective products) are detected.

[0003] When inspecting the appearance of flexible boards, the traditional method usually requires placing multiple flexible boards to be inspected in a tray, and then manually placing the tray full of flexible boards to be inspected on the flexible board inspection table. After all the flexible boards in the tray are removed, the empty tray also needs to be removed manually. Manually placing and retrieving the trays is time-consuming and labor-intensive, which seriously affects the inspection efficiency of flexible boards.

[0004] Therefore, we propose an automatic pallet loading and unloading device to solve the above problems. Utility Model Content
