After the products are in place, the operator manually activates the button on the worktable, and the clamping assembly clamps the multiple curved plate pieces.

Objective 2: The clamping assembly is equipped with multiple elastic clamping blocks inside, which can straighten the long straight edges of the product that need to be cleaned, reducing the straightness deviation. Within the cleaning depth range, after clamping, the positioning column mechanism is driven downward by the cylinder, leaving the positions of the two long edges and one short edge of the product that need to be cleaned for cleaning. Then, the cleaning mechanism automatically cleans and moves along the cleaning path, cleaning one side of the curved plate piece in sequence. After all four front sides of the curved plate piece are cleaned, the motor drives the rotating disk to automatically rotate 180 degrees, turning the back of the curved plate piece to the top. The robot automatically cleans the back of the curved plate piece. After cleaning is completed, the motor turns the curved plate piece fixture back to the front, the clamping assembly automatically opens, and multiple curved plate pieces are cleaned, and then manually unloaded.
