[0012] 1. This kind of automatic material grabbing robot arm for automobile parts processing is provided with a mechanical grabbing arm and a sliding tube. When grabbing and moving block-shaped automobile parts, the motor drives the threaded rod to rotate, and the threaded rod controls the first sliding block to approach each other, so that the mechanical grabbing arms on both sides are close to each other, and the object is grabbed from both sides of the object, and then the robot arm body drives the object to move. When it is necessary to grab a plate-like object, all the sliding tubes are pushed down at this time, and the rubber ring is squeezed on the upper surface of the plate-like object. At the same time, the vertical rod and the piston are pulled upward, so that the sliding tube generates suction, and the plate-like object is firmly adsorbed on the sliding tube, and is driven to move by the mechanical grabbing arm, so that the robot arm can not only grab and move block-shaped automobile parts, such as automobile wheels, but also adsorb and move plate-like parts, such as car window glass.

When the rubber ring contacts and presses tightly on the surface of the plate-like parts, the second electric push rod pulls the piston up to generate suction for adsorption. The entire grabbing process does not require workers to operate manually, so the purpose of automatic material grabbing is achieved, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
