[0032] An air drive component 316 and an electric drive component 317 are fixedly installed on one side of the slider guide rail 311. The air drive component 316 is connected to the splint push rod 315 through a conduit, and the electric drive component 317 is connected to the electric slider 312 through a wire. The electric drive component 317 can supply power to the electric slider 312 through the wire, so that the electric slider 312 can drive the loading rack 313 to move relatively smoothly on the slider guide rail 311. The air drive component 316 can supply air to the splint push rod 315 through the conduit, so that the output shaft of the splint push rod 315 can extend smoothly.

[0033] The adjusting member 32 includes a main base 321, which is fixedly mounted on the surface of the main table top 2 and connected to the electric drive member 317 through a wire.

At the same time, the electric drive component 317 drives the main base 321 to drive the driving wheel 322 to rotate through the wire, and the driven wheel 324 connected by the transmission chain 323 realizes the sprocket When the transmission is transmitted and the driven wheel 324 rotates, the length of the threaded stud 327 in the driven wheel 324 changes, thereby changing the height between the support plate 326 connected to the stud 327 and the main table 2, so that the height of the workpiece during processing is more uniform. During processing, the optical thickness gauge on the detection table 41 can automatically measure the thickness of the bevel area and feed back the measurement result to the slider push rod 45. The output shaft of the slider push rod 45 is extended to drive the bevel tool 46 to move on the top of the detection table 41, so that the result automatically calculated by the device is used to adjust the bevel tool depth. At the same time, the vacuum cleaner 42 on the detection table 41 collects and filters a large amount of metal dust waste generated during the processing, and discharges it through the dust exhaust pipe 43 to ensure a clean working environment. After the processing is completed, the electronic microscope measuring instrument in the detection table 41 is used to automatically separate the plates and transport them to the good product area and the defective product area respectively.
