Technical Field
[0001] This utility model relates to the field of feeding device technology, specifically an automatic feeding device that is compatible with both long and short feeding devices. Background Technology
[0002] When processing some boards, it is necessary to use an automatic feeding device to move the boards to be processed onto the equipment on the production line. However, the existing automatic feeding devices still have certain defects in use, such as:
[0003] Existing automatic feeding devices typically use four sets of suction cups to hold the board in place, and then use a robotic arm to feed it. When the board is long, it only holds the middle of the board, which can easily cause it to shake and fall off. At the same time, it is difficult to hold the board when the surface is uneven. Some devices use cylinders or electric push rods to clamp the board, but the clamping stroke is short and it is difficult to adapt to longer boards. Also, when the board is thin or has smooth edges, it is easy to fall off. Utility Model Content

[0027] In practice, the length of the telescopic frame 403 is adjusted to adjust the position of the electric suction cup 404, moving the electric suction cup 404 away from the fixed electric suction cup 401. Then, the servo motor 506 is started to drive the worm gear 505 to rotate inside the square shell 3. The worm gear 505 drives the worm wheel 504 to drive the gear 503 to rotate.

Then, the servo motor 506 is started to drive the positioning plate 601 to clamp the plate and center it. Next, the longitudinal electric push rod 405 is started to attract the fixed electric suction cup 401 and the movable electric suction cup 404 to the upper surface of the plate. Then, the longitudinal electric push rod 405 is started again to lift the attracted plate, making the plate higher than the L-shaped plate 603. Then, the horizontal electric push rod 604 is started to push the L-shaped plate 603 to the bottom of the plate.
