Description

Technical Field

[0001] The utility model relates to the technical field of PCB carrier boards, in particular to a board collecting machine using a tray. Background Art

[0002] During the PCB processing process, trays are required for both storage and transportation of PCB boards. Trays are used to load PCB boards that have been stacked in the previous process. The surface of the tray is provided with a concave shape that is used in conjunction with the PCB boards. After a PCB board is placed in each tray, the trays are stacked and ready for use in the next process. However, existing tray unloading and receiving require manual operation. That is, an empty tray is manually removed from the stacked empty trays, and after a PCB board is placed in, the trays loaded with PCB boards are manually stacked. This tray receiving method is labor-intensive and has low tray receiving efficiency. Utility Model Content
