[0034] Based on the above embodiments, a positioning cylinder 15 is arranged on one side of the bottom frame 110. During the flipping process of the bottom frame 110, the positioning cylinder 15 can press the PCB boards to prevent the PCB boards from moving during the flipping process and avoid the PCB boards from falling off the bottom frame 110.
