Description

TECHNICAL FIELD

[0002] In the prior art, many products involve a turnover process in the production process. Taking a super capacitor as an example, after one side of the super capacitor is processed, the super capacitor needs to be turned over by 180° for processing the other side. In the existing process, the super capacitor workpiece is placed in a corresponding jig, and a multi-axis robot or manual operation is needed to complete the turnover. However, the multi-axis robot turnover operation has the defect of high equipment cost, and the manual operation has the defects of poor accuracy, low efficiency, high labor cost and the like, and therefore cannot meet the production requirements. To solve the above problems, through retrieval, a clamping turnover device with publication number CN215069672U is disclosed. After the workpiece is placed in the jig, the lifting mechanism drives the carrier to rise until the jig is lifted between the two positioning cylinders, and then the two positioning cylinders move and clamp the jig. The lifting mechanism drives the carrier to lower to avoid, the turnover driving mechanism moves and drives the cylinder support, the positioning cylinder and the jig to turn over by 180°, and finally the lifting mechanism drives the carrier to rise, the two positioning cylinders are loosened and the jig is placed on the carrier, and the lifting mechanism drives the carrier to lower to complete the clamping lifting and turnover action. Although the above-mentioned device can clamp and turn over the workpiece, when the jig lifts the workpiece, the jig is prone to bending and deformation, which causes damage to the equipment and the workpiece, and irreversible loss of the equipment and the workpiece.
