AI Technical Summary
Existing laser marking equipment has a slow production cycle and is prone to large placement errors in radar manufacturing, mainly because the gripper needs to transfer the product twice, which takes a long time and is not accurate in positioning.
The design incorporates a combination of flipping, marking, moving, and pick-and-place components. By flipping and lifting the vacuum suction plate, the product is directly transferred from the flipping component to the marking position, avoiding secondary transfer before marking is completed. The vacuum suction plate then picks up the next product, reducing waiting time.
It improved production efficiency, avoided secondary positioning errors, and enhanced the accuracy of production cycle time and product positioning.
