Description

Technical Field

[0001] This utility model relates to the field of PCB board picking machines, and in particular to a PCB reflow oven back-end board picking machine. Background Technology

[0002] A search of Chinese patents revealed CN220975762U, a PCB reflow oven back-end sorting and picking device, applied in the field of PCB board grabbing technology. This invention uses a camera to photograph and identify PCB boards on the top of a conveyor optical axis frame. Software on a computer and monitor calculates the PCB board classification and positions, then moves the board to the corresponding position where it is lifted by a top plate lifting structure. The PCB board is then grabbed by an A-head or B-head grabbing structure and moved to a designated position for placement on a PCB board testing machine for subsequent functional testing. This device replaces manual PCB board sorting and picking, solving the problems of high temperature and harsh environments causing significant harm to workers and high labor costs. Furthermore, the machine picks up the PCB boards by grasping their edges, avoiding contact with components and effectively preventing component damage, thus improving production efficiency and yield.

[0003] In summary, the current board picking device does not have a board storage function. After the PCB board is inspected, it is usually removed from the conveyor platform and placed on the transfer platform by the staff. During the picking process, the staff needs to work continuously, which increases the workload and reduces the practicality. In order to solve the above problems, we propose a PCB reflow oven back-end board picking machine. Utility Model Content
