[0070] In addition, in this embodiment, a first blocking plate 512 and a second blocking plate 907 are further arranged at the front end of the feeding support frame 502 and the rear end of the blanking support frame 902 respectively to prevent the plate from sliding out; the upper bus of the group of matching rollers in the feeding roller 5, the first processing roller 6, the intermediate roller 7, the second processing roller 8 and the blanking roller 9 should be adjusted uniformly.

[0071] When the plate is processed by multiple stations and multiple production lines by using the device, the working principle is as follows:

[0072] Firstly, the plate raw material is moved to the upper side of the feeding roller 5 by artificial or stacking robot, at this time the first photoelectric switch 511 sends a signal, the first side pushing material cylinder 507 drives the first pushing plate 508 and the first block 509 to push the plate to the right end face of the positioning block 3018 to the left, realizing the side positioning of the plate, and the spring 3021 in the buffer limiting assembly is in the compressed state, and the front end clamping jaw 304 acts to clamp the plate; then the driving motor 305 of the front end clamping mechanism drives the slide plate 303 and the plate to move backward together, conveying the plate to the machining position of the first machining unit 1 (the upper side of the first machining roller 6), and it needs to be noted that when the plate passes through the third photoelectric switch 1002 at the feeding roller 5, the end point coordinate position is recorded as the origin of the machining action of the first machining unit 1, so as to facilitate the calculation of the plate machining position; after the plate is machined by the first machining unit 1, it is continuously conveyed to the upper side of the intermediate roller 7 by the front end clamping mechanism, and when the second photoelectric switch 711 sends a signal, the second proximity switch 3010 reaches the position of the second sensing block 3012, and the second proximity switch 3010 sends a signal at the same time, at this time the front end clamping mechanism releases the plate, and the plate is pushed out to the right end face of the positioning block 3018 under the action of the spring 3021, and the front end clamping mechanism returns to the feeding roller 1 and sends a signal when the first proximity switch 309 corresponds to the position of the first sensing block 3011; when the front end clamping mechanism returns to the feeding roller 1, the second proximity switch 3010 is away from the second sensing block 3012, at this time the rear end clamping mechanism moves forward until the third proximity switch 314 reaches the position of the third sensing block 3016, at this time the third proximity switch 314 sends a signal, and the plate is pushed to the left by the second side pushing material assembly 705 until it reaches the right end face of the positioning block 3018, and is buffered by the buffer positioning assembly, and the rear end clamping mechanism clamps the plate and continues to drive the plate to move backward to enter the second machining unit 2 for machining, and when passing through the third photoelectric switch 1002 at the rear end of the intermediate roller 7, the position at this time is recorded as the end point coordinate position of the second machining unit 2; finally, the machined plate is continuously driven backward by the rear end clamping mechanism until it reaches the position of the fourth photoelectric switch 906, the rear end clamping mechanism releases the plate, the plate is ejected by the spring 3021, and finally the machined plate is moved to the finished product area by artificial or stacking robot.

[0076] The first intermediate roller table 12 and the second intermediate roller table 13 are provided with a group of second side pushing assemblies at the right side of the middle part, and each of the front and rear sides of the feeding frame is provided with a group of sensing blocks corresponding to the second side pushing assemblies, and the initial position of the intermediate clamping mechanism 14 is at the front-end sensing block above the second intermediate roller table 13, when the first processing unit 1 finishes processing, the plate is conveyed to the right-end sensing block above the first intermediate roller table 12 by the front-end clamping mechanism, at this time, the intermediate clamping mechanism 14 moves to the left-end sensing block above the first intermediate roller table 12, and the plate is transferred and repositioned at the two places, then the plate is moved to the second processing unit 2 by the intermediate clamping mechanism 14 for processing, and then the plate is moved to the front-end sensing block above the second intermediate roller table 13 by the intermediate clamping mechanism 14, the rear-end clamping mechanism moves to the rear-end sensing block above the second intermediate roller table 13, and the plate is transferred and repositioned at the two places, finally, the plate is conveyed to the third processing unit 11 for processing by the rear-end clamping mechanism and then moved to the discharging position, so as to complete the processing of the plate.
