[0023] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0024] According to the instruction manual Figure 1-5It can be known that when the present invention is working, the first toothed plate chain conveyor platform 2 conveys the long strip material 1 and cuts it into square materials 4 through the linear laser cutting mechanism 23. The square materials 4 are conveyed to the tail end of the first toothed plate chain conveyor platform 2. The fourth photoelectric sensor arranged at the tail position inside the first toothed plate chain conveyor platform 2 cooperates with the external control system to control the position where the square material 4 stops being conveyed, and can also control the operation of the first robot rocker arm 3. The first robot rocker arm 3 works in cooperation with the ordinary suction cup 22 to grab the square material 4 on the first toothed plate chain conveyor platform 2 to the head of the second toothed plate chain conveyor platform 5.

[0025] The second toothed plate chain conveying platform 5 conveys the square material 4, and cuts it into end guard plates 12, disc materials 18 and waste materials 7 through the circular laser cutting mechanism 6. The first photoelectric sensor 61 corresponding to the position of the circular laser cutting mechanism 6 in the second toothed plate chain conveying platform 5 can cooperate with the external control system to control the position where the square material 4 stops being conveyed, and the circular laser cutting mechanism 6 accurately cuts it. After cutting, the second toothed plate chain conveying platform 5 conveys the cut material to the tail. The fifth photoelectric sensor arranged at the tail position in the second toothed plate chain conveying platform 5 can cooperate with the external control system to control the position where the material stops being conveyed after cutting.

[0026] The second robot rocker arm 17 rotates to drive the suction cup mechanism 16 to work, specifically, the first suction nozzle 166 at the bottom of the annular plate 163 and the second suction nozzle 167 at the bottom of the circular plate 164 respectively adsorb the end guard plate 12 and the disc material 18, and rotate to the top of the detection mechanism 11, the first suction nozzle 166 and the second suction nozzle 167 are connected to the external vacuum suction system and work, and those skilled in the art will understand that at this time, the telescopic end of the driving cylinder 165 contracts to make the disc material 18 higher than the end guard plate 12, so that space is left for the centering component 13 on the workbench 133, so that the end guard plate 12 can be placed stably on the workbench 133, the first suction nozzle 166 stops adsorbing, and the end guard plate 12 is placed on the periphery of the centering component 13 on the workbench 133, and the second suction nozzle 167 continues to adsorb the disc material 18 to ensure that the disc material 18 will not fall, and the second robot rocker arm 17 will rotate it to the top of the disc unloading mechanism 19, and the centering component 13 in the detection mechanism 11 will align and center the end guard plate 12. Specifically, the telescopic end of the first cylinder 131 is extended to drive the push rod 132 to push the inner ring of the end guard plate 12 outward to make it centered, and the telescopic end of the second cylinder 141 in the detection component 14 is extended to drive the moving rod 142 to move inward until it abuts against the outer ring of the end guard plate 12. At this time, the distance sensor 143 works to detect the ring width; the slide groove 134 can ensure the stability of the movement of the push rod 132 and the moving rod 142, and the second photoelectric sensor 135 in the slide groove 134 can detect whether the end guard plate 12 is placed on the workbench 133, and can cooperate with the external control system to make the centering component 13 and the detection component 14 work;

[0027] After the second robot rocker arm 17 works to transfer the disc material 18 to the top of the disc unloading mechanism 19, the telescopic end of the driving cylinder 165 is extended to make the disc material 18 lower than the first suction nozzle 166, and the second suction nozzle 167 stops adsorption, and the disc material 18 is placed on the disc unloading mechanism 19 and collected. The second robot rocker arm 17 drives the suction cup mechanism 16 back to the top of the tail of the second toothed plate chain conveying platform 5, ready for the next grabbing.

[0028] At the same time, during the working process of the second robot rocker arm 17, the first toothed chain conveyor platform 2, the linear laser cutting mechanism 23, the first robot rocker arm 3, and the second toothed chain conveyor platform 5 continue to work without waiting, which greatly improves the work efficiency. Moreover, the second toothed chain conveyor platform 5 transports the waste 7 to the crusher 8 for crushing, and collects it through the waste 7 truck.

[0029] During the whole working process, the first toothed plate chain conveying platform 2, the first robot rocker arm 3, the second toothed plate chain conveying platform 5, the crusher 8, the second robot rocker arm 17, the disc unloading mechanism 19 and the detection mechanism 11 are all working in the peripheral protection mechanism 21 to ensure the safety and stability of the work. As for the suction cup mechanism 16, it is frequently used, has high air tightness requirements, and is easily damaged during work. Therefore, the present invention sets a maintenance area 15 for repairing and maintaining it.

[0030] The present invention can perform laser cutting, transmission, use a robot to sort the end guard plate 12 and the disc material 18 through a special suction cup mechanism 16, handle waste 7, detect the size of the end guard plate 12, and provide safety protection. It has complete functions, a high degree of automation, high sorting efficiency, cost savings, a reasonable process, high safety, and strong applicability.

[0031] It should be emphasized that the entire production line in the present invention has a reasonable workflow, a high degree of automation, and complete functions. The suction cup mechanism 16 is specially designed, which can adsorb multiple types of materials and can be used in conjunction with the components in the detection mechanism 11. The suction cup mechanism 16 and the detection mechanism 11 are designed in a linkage manner.

[0032] Among them, the disc unloading mechanism 19 includes a third photoelectric sensor 193, an inclined platform 194 and a collection vehicle 20. The inclined platform 194 is set on the ground and has a smooth surface. The upper surface of the high side of the inclined platform 194 is used to receive the disc material 18, and a groove 192 is opened on its surface. After the disc material 18 is placed on the inclined platform 194, the third photoelectric sensor 193 in the groove 192 is triggered to sense and cooperate with the external control system to let the second robot rocker arm 17 leave. The collection vehicle 20 is set at the tail end of the low side of the inclined platform 194 to collect the disc material 18. Baffles 191 are set on both sides of the inclined platform 194 to prevent the disc material 18 from falling from both sides.

[0033] Among them, a limiting rod 169 is vertically arranged between the upper surface of the circular plate 163 and the top of the fixed frame 162, and a clamping plate 168 is arranged at the position of the limiting rod 169 corresponding to the edge of the upper surface of the circular plate 164. A limiting hole is opened at the position of the clamping plate 168 corresponding to the position of the limiting rod 169, and the limiting rod 169 passes through the limiting hole, thereby ensuring the stability of the movement of the circular plate 164 and limiting its stroke.

[0034] The protection mechanism 21 is a fence or a safety grating to ensure the safety of work.

[0035] Among them, the waste vehicle 7 and the collection vehicle 20 are both provided with long handles 9, which facilitate the personnel to take out the vehicles during work.

[0036] In the present invention, the fourth photoelectric sensor and the fifth photoelectric sensor are not drawn in the drawings of the specification, but their functions and installation methods are the same as the first photoelectric sensor 61. The external control system, the external vacuum suction system and the necessary power supply system are all prior art and will not be described here. In addition, the first robot rocker arm 3 and the second robot rocker arm 17 both perform a shaking action after clamping the material to ensure the stability of the material adsorption. If it falls during the shaking process, the suction cup works abnormally, and an alarm can be issued to remind personnel.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
