It has the advantages of fast marking speed, high marking accuracy, and good continuous working stability. It is widely used in various fields such as electronics, hardware, aviation devices, auto parts, precision instruments, etc. In laser marking, a robotic arm can be used for automatic loading and unloading to improve work efficiency.

[0003] Patent number CN214520203U is a mechanical arm for loading and unloading materials, including a base and a rotating table. The rotating table can rotate 360 ​​degrees at the upper end of the base to adjust the grabbing position of the device. Through the straight extension rod, long cable, movable pulley, connecting rod, rope winding wheel and vertical rod, the device abandons the complex rotating mechanical structure, and fixes the straight extension rod and the vertical rod in one piece, and further triangularly reinforces the straight extension rod and the vertical rod through the main support rod and the lower support foot, so that the strength of the device is higher. Through the cooperation of the movable pulley, the long cable and the rope winding wheel, the claw machine for grabbing materials is lifted up and down, so that the mechanical arm can easily lift heavy objects.
