[0011] Laser cutting: The processed steel plate material is placed on the bearing table, and the processing material and the positioning edge groove are fixed and fixed by the fixed edge groove. The processing shape and size are set by the program, so the column pneumatic control system will adjust the supporting column state according to the set cutting path to avoid damage to the bearing table caused by laser cutting.

[0012] Conveying and flipping: By controlling the magnetic suction transfer unit, the working state of each electromagnetic suction head can be adjusted independently, so the electromagnetic suction heads in different positions can work together to suck up steel plate materials of any shape on the carrier. The electromagnetic suction head that sucks up the steel plate material is transferred to the top of the conveying table through the movement of the movable beam. By controlling the electromagnetic suction head to descend and demagnetize, the transfer of the processed steel plate material from the carrier to the transmission table is completed. The transmission table is controlled by the motor to realize the movement of the processed steel plate material to the flipping conveyor mechanism. At the same time, the first motor of the flipping conveyor mechanism starts to control the rotation of the transmission roller to realize the separation of the steel plate material from the conveying table. By controlling the second motor of the flipping conveyor mechanism, the main control gear drives the fork teeth on both sides of the main shaft to rotate, and the fork teeth support the steel plate to the opposite side of the main shaft to complete the flipping of the steel plate.

[0013] Dust removal and grinding: The single-side conveying roller of the flip conveyor mechanism is connected to the feeding port of the grinding mechanism.

The material steel plate that has been roughly ground by the grinding wheel passes through the middle protective partition inside the grinding mechanism as the internal transmission roller of the grinding mechanism rotates. By adjusting the height of the protective partition adjustment port, the large-sized steel slag that falls off due to the grinding wheel cutting is blocked from passing through. The blocked steel slag automatically falls to the bottom waste collection bin when the use of the steel plate material ends or accumulates. At the same time, by adjusting the distance, angle, and pressure between the steel brush head and the steel plate material, high-speed rotation fine grinding begins. The material steel plate rotates with the internal transmission roller to complete the grinding wheel slag cutting and steel brush grinding. The smoke and dust generated during the whole process is collected by the dust removal system connected to the protective box.

The pneumatic system of each supporting column is used to adjust the state of each supporting column, and the supporting columns within the influence range of the laser cutting path are set to remain in a retracted state, which can effectively prevent the laser from penetrating the steel plate and damaging the bearing platform.

[0016] 2. Through the coordinated operation of the positioning side groove and the fixing side groove, steel plate materials of any shape can be fixed on the bearing platform, avoiding the problem of irregular-shaped materials being unable to be fixed and improving work efficiency.

[0017] 3. Universal wheels are provided on the supporting columns to facilitate the movement and adjustment of the position of the steel plate material on the bearing platform, saving manpower.

[0018] 4. The magnetic transfer unit can be used to transfer the cutting material to the conveyor table. The conveyor table is docked with the flip conveyor mechanism to complete the transfer of the cutting material to the flip conveyor mechanism. The cutting material can be turned over by rotating the fork teeth of the flip conveyor mechanism, so that the slag and burr side face up for easy grinding.

[0019] 5. The grinding wheel mechanical arm and steel brush head in the grinding mechanism can be used to remove the slag and burrs of the laser cutting of the steel plate material. By adjusting the distance between the grinding wheel mechanical arm and the steel plate material, large-size slag can be cut and removed, effectively improving the grinding efficiency. Fine grinding can be achieved by adjusting the angle and pressure of the steel brush head. At the same time, the slag and debris removed by cutting are swept into the collection bin through the protective partition adjustment port, and the whole process is collected by the dust removal system of the protective box connected to the protective box. It improves production efficiency, protects the health and safety of personnel, and effectively improves the appearance quality of products. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] When material cutting is required, the support platform 1 is placed on the processed steel plate material, and the fixed edge groove 14 ensures that the processed material and the positioning edge groove 13 are firmly attached and fixed. The processing shape and size are set by the program, so the column pneumatic control system 12 will adjust the state of the supporting column 11 according to the set cutting path to avoid damage to the support platform 1 due to laser cutting.

[0035] When the steel plate material that needs to be cut is to be transferred, the working state of each electromagnetic suction head 31 can be independently adjusted by controlling the magnetic suction transfer unit 2, so that the electromagnetic suction heads 31 at different positions work in combination to suck up steel plate materials of any shape on the carrier 1.

The blocked steel slag automatically falls to the bottom waste collection bin 57 as the use of the steel plate material ends or accumulates. At the same time, by adjusting the distance, angle, and pressing force between the steel brush head 56 and the steel plate material, high-speed rotation fine polishing is started, and the material steel plate rotates with the internal transmission roller 53 to complete the grinding wheel slag cutting and steel brush polishing. The smoke and dust generated during the whole process are collected by the dust removal system 58 connected to the protective box 51.
