[0083] The main controller is also electrically connected to the eighth driving source. In this embodiment, the number of rotations of the loading barrel 19 or the number of workpieces taken from the turnover material tray 3 can be counted to determine whether the jig 14 on the jig positioning mechanism is filled with materials. When the jig 14 on the jig positioning mechanism is filled with materials, the main controller controls the eighth driving source to drive the belt 30 to rotate. When the positioning switch detects that the second placement tray 31 moves to the effective clamping area of ​​the tray clamping arm 51, the main controller controls the eighth driving source to drive the belt 30 to stop. Then the main controller controls the tray clamping arm 51 to clamp the jig 14 on the jig positioning mechanism to the second placement tray 31 of the jig conveying mechanism. After that, the jig 14 on the jig conveying mechanism can be transferred to the next process by manual handling or other methods.
