[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0019] Example: An automatic loading and unloading device for flat workpieces includes a machine base 1, a tray loading assembly 3 and a tray unloading assembly 5 disposed on the front side of the machine base 1, a tray transfer assembly 4 disposed on the top front side of the machine base 1, a workpiece loading conveyor belt 14 and a workpiece unloading conveyor belt 15 disposed on the rear top side of the machine base 1, a multi-axis robot arm 7 disposed on the machine base 1, and a lower detection camera 17 disposed on the machine base 1. The multi-axis robot arm 7 is equipped with a workpiece transfer suction cup 8. The tray loading assembly 3 and the tray unloading assembly 5 have similar structures. Similarly, the material tray loading assembly 3 includes a horizontally arranged infeed and outfeed conveyor belt 30, material tray guide strips 31 arranged on both sides of the infeed and outfeed conveyor belt 30, and a lifting module 32 arranged between the infeed and outfeed conveyor belts 30. The material tray transfer assembly 4 includes a transfer beam 40 spanning the material tray loading assembly 3 and the material tray unloading assembly 5, a transfer linear module 42 arranged on the transfer beam 40, a transfer lifting cylinder 43 arranged on the transfer linear module 42, and a transfer suction cup 41 arranged on the transfer lifting cylinder 43.

[0020] The above-mentioned simultaneous loading and unloading is achieved through the workpiece loading conveyor belt 14 and the workpiece unloading conveyor belt 15. The multi-axis robot arm 7 can perform material picking and tray placement. The material tray transfer component 4 can transfer the empty material tray on the material tray loading component 3 to the material tray unloading component 5, realizing loading and unloading on the same machine. The equipment has low cost and small footprint. The bottom of the flat workpiece can be automatically detected by the bottom detection camera 17.

[0021] To facilitate the automatic conveying of defective products, the top of the machine 1 is equipped with an NG conveyor line.

[0022] The workpiece unloading conveyor belt 15 has guide strips 16 on both sides at the end of its stroke. The guide strips 16 are in the shape of an "eight" and guide and limit the unloading of flat workpieces, making it easier for the multi-axis robot arm 7 to pick up the workpieces.

[0023] To facilitate the inspection of flat workpieces during loading and unloading, an upper inspection camera 6 is provided on the top of the machine base 1, and the top surfaces of the material tray loading assembly 3 and the material tray unloading assembly 5 are both within the detection range of the upper inspection camera 6.

[0024] The machine base 1 is equipped with a tilting beam 13, which spans the workpiece loading conveyor belt 14 and the workpiece unloading conveyor belt 15. A tilting lifting cylinder 11 is mounted on the tilting beam 13, and a rotary cylinder 10 is mounted on the rotary cylinder 10. A tilting suction cup 9 is mounted on the rotary cylinder 10, and the rotation axis of the tilting suction cup 9 is horizontal. This allows for convenient tilting of flat workpieces during unloading, facilitating automatic unloading.

[0025] The lifting module 32 includes a lifting linear module 321 and a lifting tray 320 disposed on the lifting linear module 321, which facilitates the layer-by-layer lifting or lowering of the tray.

[0026] To facilitate precise guidance of the multi-axis robotic arm 7, a guide camera 12 is provided on the multi-axis robotic arm 7. During operation, the multi-axis robot 7 picks up flat workpieces from the tray in the tray loading assembly 3 and transfers them to the lower inspection camera 17 for inspection. After passing the inspection, the flat workpiece is placed on the workpiece loading conveyor belt 14. The tray transfer assembly 4 transfers the empty tray in the tray loading assembly 3 to the tray unloading assembly 5. The flipping suction cup 9 flips the flat workpiece on the workpiece unloading conveyor belt 15 by 180°, and the multi-axis robot 7 picks up the flat workpiece on the workpiece unloading conveyor belt 15 and transfers it to the lower inspection camera 17 for inspection. If the flat workpiece is unqualified, it is placed on the NG conveyor belt 2 for delivery; if the flat workpiece is qualified, it is placed in the empty tray of the tray unloading assembly 5.
