A tray feeding mechanism

Abstract

The present invention discloses a tray feeding mechanism, including a frame, a support seat, a guide, a blocking mechanism, a bracket, a servo motor, a first gear, a feed nut, a second gear, a lead screw, a guide plate, a limit rod, a suction mechanism, a tray, a bellows, a cover plate, and a fan. The raw material is placed in the tray and placed on the upper end of the support seat. The servo motor drives the feed nut connected to the second gear to rotate through the first gear. When the feed nut rotates, the lead screw drives the guide plate to move right along the limit rod. When the proximity switch is triggered, the electromagnet is energized and attracted to the tray. When the servo motor rotates to a set angle, the electric push rod pushes the L-shaped stopper through the support seat to block the tray from moving forward. Then the servo motor rotates to a set angle again to compress the spring, thereby reacting the tray to fix it. The device has a simple structure, can automatically transfer the tray, and can accurately position and clamp the tray. At the same time, it can automatically remove chips, simplify the production process, and improve production efficiency.
