[0104] By adopting the technical solution disclosed in the present invention, it is possible to achieve:

[0105] When using this device, the workbench 1 is placed horizontally on an external equipment rack, and the front side of the workbench 1 is tilted downward at a certain angle. The driving motor 6-2 provides power to drive the dual output shaft gearbox 6-3 to work.

[0106] The upper output shaft of the dual-output shaft gearbox 6-3 drives the clutch support shaft 8-1 to rotate, and then the clutch support shaft 8-1 drives the clutch wheel 8-3 located on the clutch frame 8-2 to rotate through the gear set;

[0107] The output shaft at the lower end of the dual-output shaft gearbox 6-3 drives the transmission sprocket 9-1 thereon to rotate, which in turn drives one of the transmission support shafts 7-4 located on the connecting frame 7-1 to rotate through the chain transmission.

[0108] When the panel 3 moves, the chain is supported by the tension sprocket 9-4 and the swing arm 9-3, thereby tensioning the chain. When the panel 3 drives the bracket 5-1 and the connecting frame 7-1 to move, the swing arm 9-3 rotates to keep the chain tensioned.

[0109] When placing a workpiece:

[0110] The worm 5-5 is driven to rotate by the rotating motor 5-6, and then the worm 5-5 drives the mounting frame 5-3 to rotate through the meshing worm gear 5-4. The mounting frame 5-3 slides in the arc groove 5-2 and drives the clamping belt roller 10 to rotate, thereby adjusting the angle between the clamping belt roller 10 and the supporting belt roller 4. During this process, the driven runner 7-3 is kept from contacting any of the driving runners 7-2. At the same time, the clutch frame 8-2 is pushed to rotate by the clutch electric push rod 8-4, and the clutch frame 8-2 drives the two clutch wheels 8-3 to separate from each other and put in the workpiece;

[0111] When one end of the workpiece abuts against the supporting belt roller 4 and the other end of the workpiece abuts against the clamping belt roller 10, the clamping belt roller 10 is rotated to be perpendicular to the supporting belt roller 4. At this time, the driven pulley 7-3 abuts against one of the driving pulleys 7-2. At this time, the clamping belt roller 10 moves and drives the end of the workpiece abutting thereon to rotate away from the supporting belt roller 4. The clutch frame 8-2 is driven by the clutch electric push rod 8-4 to rotate and the two clutch pulleys 8-3 are pressed tightly. At this time, the supporting belt roller 4 moves and drives the end of the workpiece abutting thereon to move toward the side of the clamping belt roller 10, and then the supporting belt roller 4 and the clamping belt roller 10 cooperate with each other to move the workpiece to be perpendicular to the supporting belt roller 4, and the workpiece is attached to the clamping belt roller 10;

[0112] During the above-mentioned operation of placing the workpiece, when the workpiece is directly placed flat on the supporting belt roller 4 without contacting the clamping belt roller 10, the above-mentioned operation of adjusting the position of the workpiece is not performed;

[0113] Then the driving motor 6-2 stops working in standby mode, and the dual-output shaft gearbox 6-3 stops outputting, and then the clamping belt roller 10 is rotated and laid flat, and then the clamping belt roller 10 and the supporting belt roller 4 clamp the workpiece, and at this time the active runner 7-2 is against the other driven runner 7-3, that is, the belt surface of the clamping belt roller 10 contacting the workpiece and the belt surface of the supporting belt roller 4 contacting the workpiece have the same moving direction, and at this time the driving motor 6-2 outputs to work, that is, to realize the limit adjustment of pushing the workpiece to move.

[0114] The technical advantages that can be achieved by adopting the above technical solution are as follows:

[0115] 1. This device uses a clamping belt roller and a supporting belt roller to clamp and limit the workpiece. At the same time, the clamping belt roller can be rotated and opened to realize the feeding of the workpiece;

[0116] 2. A common drive motor is used between the clamping belt roller and the supporting belt roller to realize stepping drive. In addition, two active pulleys are set, and a set of transmission support shafts are used to realize transmission. A driven pulley is set on the end shaft of the clamping belt roller, thereby realizing different stepping directions of the clamping belt roller at different positions;

[0117] 3. The transmission between the dual output shaft gearbox and the supporting belt roller is realized through the clutch wheel. The feeding of the clutch wheel is controlled by the clutch frame, thereby realizing the start and stop of the supporting belt roller when the drive motor is working.

[0118] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features.
