[0036] Specifically, the detection mechanism 2 includes a gasket detection slide 201, a laser displacement sensor 1 202, a linear laser 203, a laser displacement sensor 2 204, a camera lens 1 205, a light source 1 206, a laser displacement sensor 3 207, a camera lens 2 208, a light source 2 209, and a laser displacement sensor 4 210. The gasket detection slide 201 is installed on the side of the frame 6 and is located above the short conveyor belt 301. The linear laser 203 is installed on the gasket detection slide 201. The laser displacement sensor 1 202 is installed on one side of the linear laser 203. The camera lens 1 205 is installed inside the frame 6 and is located above the short conveyor belt 301. The light source 206 is installed at the lower end of the camera lens 1 205. The laser displacement sensor 2 204 is installed at the material receiving end of the camera lens 1 205.

Laser displacement sensor 307 is installed at the material receiving end of camera lens 208. Laser displacement sensor 4210 is installed inside the frame and is located in front of sorting mechanism 4.
[0038] Specifically, the sorting mechanism 4 includes a defective product pneumatic push mechanism 401 and multiple sets of good product pneumatic push mechanisms 402. Both the defective product pneumatic push mechanism 401 and the multiple sets of good product pneumatic push mechanisms 402 are installed inside the frame 6, and the defective product pneumatic push mechanism 401 is located in front of the multiple sets of good product pneumatic push mechanisms 402.
[0039] Specifically, the storage mechanism 5 includes a defective product pad tray 501 and multiple sets of good product pad trays 502, as well as a dirty and oily pad tray 503. The defective product pad tray 501 and multiple sets of good product pad trays 502 are both located on the lower inner side of the frame 6.

The dirty and oily pad tray 503 is located at the tail of the frame 6 and is located below the discharge end of the long conveyor belt 304.
[0040] Working principle: When the equipment is started, the operator pours various types of pads to be sorted into the pad feeding port 101. The various pads enter the pad vibrating plate 102, are automatically mixed and arranged, and then enter the pad detection slide 201 through the pad straight vibration slide 103. When the pad passes the laser displacement sensor 202, the laser displacement sensor 202 activates the line scanning laser 203. The line scanning laser 203 detects the flatness and thickness of the pad, compares it with the threshold to determine whether it is qualified, and records the data.
[0041] When the gasket is conveyed to the laser displacement sensor 204 via the short conveyor belt 301, the laser displacement sensor 204 wakes up the camera lens 205 and the light source 206 to detect gasket defects, distinguish scratches, mark residues, rust and dirt, compare them with the threshold to make a judgment, and record the data.
[0042] When the gasket is flipped by the gasket flipping mechanism 302 at the end of the short conveyor belt 301 and enters the long conveyor belt 304, and is conveyed to the laser displacement sensor 207 through the gasket guide groove 303, the laser displacement sensor 207 wakes up the camera lens 208 and the light source 209 to detect defects on the other side of the gasket, distinguish scratches, mark residue, rust and dirt, compare them with the threshold to determine the defects, and record the data.
[0043] When the gasket is conveyed to the laser displacement sensor 210 via the long conveyor belt 304, the laser displacement sensor 210 activates the defective product pneumatic push mechanism 401 and multiple good product pneumatic push mechanisms 402 based on the comprehensive judgment results of the line scan laser 203, camera lens 1 205, and camera lens 2 208. This causes the defective gasket to enter the defective gasket tray 501, the washable dirty and oily gasket to enter the dirty and oily gasket tray 503, and the good gasket to enter the corresponding multiple good gasket trays 502 according to the detection and classification.
[0044] This equipment can sort 6 types of pads. If the number of pad types increases or decreases, the good quality air push mechanism 402 and the good quality pad tray 502 can be increased or decreased accordingly. The laser displacement sensor 210 of this equipment uses the running speed of the long conveyor belt 304, combined with the comprehensive judgment results of the line scan laser 203, camera lens 1 205, and camera lens 2 208, to accurately wake up the action time of the air push mechanism, thereby achieving the sorting effect of multiple pads.
