[0026] When the present invention is in use, the stroke of the finger cylinder is set in advance according to the inner diameter of the retainer, and the finger cylinder drives the support plate 1 and the support plate 2 to separate from each other to support the retainer. Then the movable seat actuates the cylinder to drive the movable seat to move upward, and other structures are used to drive the entire manipulator to move, so as to achieve the purpose of moving the retainer. The retainer is driven to move in the form of "supporting the inner mouth", so that when the retainer is placed, the position is not offset, which is convenient for subsequent processing procedures. And when grasping, the success rate is relatively high.

[0027] In the present invention, the female column of the contact switch and the male column of the contact switch are used to support and pick up the retainer after the movable seat is lowered into position, thereby ensuring the success rate of grabbing.

[0028] In summary, the retainer production robot provided by the present invention can improve processing efficiency and has accurate placement, and is suitable for industrial processing. BRIEF DESCRIPTION OF THE DRAWINGS
