[0064] Step S1, the plate is placed in the pretreatment device 1 to perform pretreatment operation, the dust on the surface of the plate is removed, the defect information and the size information of the plate are obtained, and the plate is flattened;

[0065] Step S2, then the plate is sent to the shearing machine 26, and the plate is sheared by cooperation of the upper cutter 40 and the lower cutter 43;

[0066] Step S3, after shearing, the sheared plate is sent to the flattening machine 25 for flattening treatment;

[0067] Step S4, after flattening, the plate is detected for quality by the detection box 19, the qualified plate is directly taken off and placed in the special placing rack 29, and the plate which can be processed again is sent to the shot blasting machine 28 for burr treatment;

[0068] In step S2, the following steps are further included:

[0069] Step S21, during shearing, different specifications of the upper cutter 40 can be quickly replaced according to actual conditions, and in addition, the debris on the upper cutter 40 is cleaned by the cleaning brush 41 after one-time shearing, so as to avoid affecting the shearing quality next time.

[0070] Working principle: first, the plate is pretreated in the pretreatment device 1 to ensure that the plate surface is clean, then the plate is sent to the shearing machine 26 for shearing to shear the plate into the required size, then the sheared plate is flattened by the flattening machine 25 to ensure that the final product after shearing is not deformed, then the sheared product is sent to the detection box 19 for quality detection, through the laser range finder 20, the visual recognition device 21 and the laser distance sensor 22, the accuracy of the shearing position is improved, and whether the quality of the plate is qualified is detected, if the shearing size and surface defects of the product are all normal, but there is burr at the cutting position, then the sheared plate product is sent to the shot blasting machine 28 for rapid polishing of the plate edge, which can quickly remove the burr to make the plate surface reach a good smoothness, while avoiding excessive polishing to cause deformation or damage of the plate, through secondary processing, the plate is recovered, and the production qualified rate and quality of the product are improved.
