Before the supporting portion 52 and the limiting portion 51 rise, the limiting projection 31 is below the supporting pusher 44; after the limit protrusion 31 and the supporting portion 52 rise, the limit protrusion 31 can be just clamped inside the supporting pushing member 44, at this time, the first driving member 41 pushes the limit protrusion 31 to move toward the position B, and the limit protrusion 31 and the tray 3 are integrated, so that the tray 3 also moves toward the position B.

The second driving member 61 is in an extended state before the pallet 3 is pushed onto the bullseye wheel 64 near the backboard mechanism 2 so that the movable guide plate 62 is about to contact and guide with the workpiece mounting plate 32 of the pallet 3, and when the pallet 3 is pushed onto the bullseye wheel 64 with the movable guide plate 62 and the fixed guide plate 63 together guiding the pallet 3, the second driving member 61 is retracted so that the movable guide plate 62 is retracted after the workpiece mounting plate 32 is brought into alignment with the two planes of the backboard 27.

The clamping driving piece 24 drives the sliding plate 23 to move to the right until the sliding plate is clamped to the left of the workpiece mounting plate 32, the right of the workpiece mounting plate 32 is clamped to the limiting plate 25, the pneumatic clamp 26 is pressed down to press the workpiece mounting plate 32, and the workpiece 7 is fixed because both sides of the workpiece mounting plate 32 are clamped.

After the workpiece 7 is secured, any inspection and assembly process operations may be performed on the workpiece 7.

The release of the tray 3 is then performed in reverse order as described above.

The last tray 3 flows to C and the next tray 3 continues as described above.
