Small magnetic adsorption mechanism

The utility model provides a small magnetic adsorption mechanism, which structurally comprises a mounting support, a needle type air cylinder, a sliding plate and a fixed seat which are arranged on the mounting support, the needle type air cylinder is supported on the center position of the surface of the sliding plate through a support rod, and the sliding plate is connected with the fixed seat through a guide rod. When working, the needle type air cylinder descends to respectively push the sliding plate, the guide rod and a magnet to descend, the magnet automatically adsorbs and transmits a battery protective plate to a processing device, then the needle type air cylinder rises to drive the magnet to go up, and the magnet loses magnetism to demagnetize and release after keeping away from the battery protective plate, completes actions, and is extremely simple and accurate in the whole process, solves the problems of slow efficiency and reject ratio of traditional manual operation, and improves reliability and stability when a whole production process device runs. The small magnetic adsorption mechanism is small in volume and convenient to mount, is suitable for operation demands of various assembly line process equipment, and is wide in applicability.
