Abstract: A turnover mechanism is used for turning a fixture and a workpiece positioned on the fixture, which includes a support bracket, a first turning mechanism, a movement mechanism, and a second turning mechanism. First turning mechanism includes a first rotary driver, a first clamping driver and two first clamping members oppositely positioned on the first clamping driver. The first rotary driver is positioned on the support bracket and connected to the first clamping driver. The first clamping driver drives the first clamping members to clamp the fixture and the workpiece. The first rotary driver rotate the first clamping driver and the two first clamping members to such that the fixture is driven to be rotated on a reverse side. The movement mechanism reaches the first turning mechanism to transfer the workpiece to the second turning mechanism. Second turning mechanism is mounted on the support bracket, clamping and turning the workpiece.

Abstract: A hanging module includes a fixing rod, a support arm, a plurality of fasteners, and a hanging assembly positioned on the support arm by the plurality of fasteners. The support arm is fixed to the fixing rod. The support arm defines a groove. The hanging assembly includes a locking member and a hanging member fixed to the locking member. The hanging member is received in the groove, and fixed to the locking member by the plurality of fasteners.
