For a clearer understanding of the principles of the invention, the following further describes the processing of the apparatus:
1) The preparation stage: connecting conveying and conveying equipment with power equipment, connecting an air cylinder, a material pump with an air supply equipment, connecting a material pump 554 with a material supplementing valve 5451, connecting an electric element and a sensor with a PLC 8, adjusting the position of each structure according to the plate to be processed, setting the operation parameters of each device according to the processed plate, setting the pressure of a compression roller 52 of a trimming mechanism 3 to be 0.45-0.53Mpa, and setting the rotating speed of a main shaft to be 0.68-0.72m/s; the pressure of the compression roller 52 of the edge repairing mechanism 5 is 0.45-0.53Mpa, the running speed of the driving roller 51 is 0.6-0.7m/s, and the setting parameters of the transverse edge and the longitudinal edge are consistent; the conveying speed of the stacking mechanism 7 is 0.58-0.62m/s; the pressures of the pressure regulating valves 57 of the pushing cylinder 543, the clamping cylinder 548 and the feeding cylinder 5452 are set to 0.28 to 0.37Mpa, 0.36 to 0.48Mpa and 0.47 to 0.53Mpa, respectively; the pressure regulating valve 57 of the material pump 554 is 0.1-0.14Mpa; the rotary encoder 521 adopts ohm dragon E6B-CWZ6C (2000P/R), and sets pulse parameters of the rotary encoder, namely, the photoelectric switch 549 senses that the plate starts 1750 to 1850 pulses to start feeding, and 7800 to 8200 pulses control the trimming mechanism to convey the plate; and setting to finish the operation of the opening device. The PLC 8 adopted in the project is an XD3-60T-E controller of the tin-free electric.
2) And (3) feeding: on the feeding mechanism 2, a plurality of laminated plates are orderly stacked on the fork teeth of the forklift type lifting frame, a processing program is started, and the hydraulic cylinder pushes the lifting rear wall and the fork teeth to lift the laminated plates to slowly rise. When the pressing plates on the fork teeth are lifted to a certain height, the pressing plates touch the induction heads of the plate in-place inductor, the plate in-place inductor feeds back touch signals to the PLC, and the PLC controls the forklift type lifting frame to stop lifting by controlling the action of the hydraulic cylinder. Then, the vacuum chuck of the material grabbing device stretches out downwards, the pressing plate is driven to lift upwards after being sucked, the chuck lifting positioning sensor is touched to stop lifting when the pressing plate is lifted to a preset height, and the clamping claw is folded inwards to clamp the pressing plate. After the clamping action is completed, the vacuum chuck loosens the pressing plate, and the PLC controller controls the material transfer mechanism to move transversely to transfer the grabbed pressing plate to the material inlet of the pressing plate trimming machine. When the pressing plate enters the material inlet of the pressing plate trimming machine, the clamping claw releases the pressing plate (the sensor is also arranged at the material inlet of the pressing plate trimming machine), and the material transfer mechanism resumes the position to prepare for grabbing and transferring the next pressing plate. After the grabbing and transferring of one pressing plate are completed, the program starts the feeding action of the next pressing plate, so that the pressing plates stacked on the fork teeth are continuously conveyed to a pressing plate trimming machine for trimming.

The outer ring of the bearing at the two ends of the main shaft rotates at a high speed along with the main shaft, and the lubricating oil in the bearing can move to the outer ring due to the centrifugal force generated by the rotation of the outer ring, which is quite beneficial to the ball bearing, so that on one hand, the lubricating effect of the lubricating oil can be better concentrated at the outer ring track of the roller, and on the other hand, the actual rolling distance of the roller is reduced when the main shaft rotates for one circle, thereby greatly prolonging the service life of the bearing.
4) And a transverse rim charge collecting procedure: the laminated board passes through waste material mechanism 4, and panel passes through transfer board 41, and the rim charge saw cuts the back and falls on collecting plate 42 from transfer board 41 both sides to the lower extreme of collecting plate 42 is neatly arranged under the effect of pin 43, collects and unifies the rim charge and handle after full.
