In addition, the entire clutch pressure plate cover production requires a large number of workers, exacerbating the factory's labor shortage problem. The combination of these existing problems makes traditional manual production unable to adapt to the production control and quality control of modern industry, and it is difficult to meet the urgent needs of modern industry for efficiency and production standards.

[0033] The robot gripper device is an industrial six-joint robot gripper device, and there are three of them, namely a first robot gripper device 19 , a second robot gripper device 20 and a third robot gripper device 21 .

Depending on the number of random inspections set by the system, some workpieces can skip the end-of-line inspection conveyor belt 17 and go directly to the unloading device 18.
[0035] Among them, the arrangement positions of the above-mentioned devices are arranged in a rectangular production route as a whole, and the destacker 1, transition table 2, fifth exchange table 12, sixth machine tool 13, sixth exchange table 14, dynamic balancing machine 15, end-of-line sampling conveyor belt 17 and unloading device 18 are located on one long side of the production route; the second machine tool 5, second exchange table 6, third machine tool 7, third exchange table 8 and fourth machine tool 9 are located on the other long side of the production route; the first machine tool 3 and the two-dimensional visual inspection and positioning device 4 are located on one short side of the production route; the fifth machine tool 11 is located on the other short side of the production route; in addition, the fourth exchange table 10 and the seventh exchange table 16 are arranged on the inner side of the rectangular production route and are located on the opposite side of the fifth machine tool 11.

[0038] like Figure 4 As shown, the two-dimensional visual inspection and positioning device 4 includes a carrier 4a, which can be used for temporary storage and / or turning over of the workpiece. An angle detection camera 4b is provided on the carrier 4a via a bracket. The angle detection camera 4b is connected to a 2D angle detection PC terminal 4c equipped with a two-dimensional visual inspection system, and the 2D angle detection PC terminal 4c is connected to the system control device. The six bosses of the workpiece are visually photographed by the angle detection camera 4b. The two-dimensional visual inspection system analyzes the data of the photographed image, calculates the distribution and symmetry of the six bosses, and obtains an optimal processing angle.

The PLC controller 22 performs information exchange through the human-machine interface 23 (HMI).
[0040] The working process of this system is as follows: First, the pallet containing the product is manually loaded onto the depalletizing table 1a and positioned. The pallet is then depalletized by the depalletizer 1 and the first robotic gripper device 19. The depalletized workpiece is placed on the transition table 2 for adjustment. The workpiece is then transferred to the first machine tool 3 for the inner edge turning process. The relative angle is adjusted by the two-dimensional visual inspection and positioning device 4. The workpiece is then transferred to the second machine tool 5 for milling the six-sided boss groove and two side surfaces. It is then transferred to the second exchange table 6 for adjustment. The exchange table is set according to the process requirements and can be used for production rhythm adjustment, workpiece flipping adjustment, and transfer adjustment between various workstations. The exchange tables described below all have the above functions and will not be repeated below.
[0041] The second robot gripper device 20 then performs the transfer. The second robot gripper device 20 transfers the workpiece from the second exchange table 6 to the third machine tool 7, processes the reset spring groove of the workpiece, and then transfers it to the third exchange table 8 for adjustment.
[0042] Next, the third robot gripper 21 transfers the workpiece from the third exchange table 8 to the fourth machine tool 9 for drilling processing. It then undergoes adjustment on the fourth exchange table 10, countersinking on the fifth machine tool 11, adjustment on the fifth exchange table 12, separation lever mounting hole processing on the sixth machine tool 13, adjustment on the sixth exchange table 14, and dynamic balancing testing of the workpiece on the dynamic balancing machine 15. Finally, it enters the seventh exchange table 16 for adjustment.
[0043] According to the random inspection settings, some workpieces are transferred from the seventh exchange table 16 to the end-of-line random inspection conveyor belt 17 through the second robot gripper device 20 to check whether each processing dimension is qualified, and finally enter the unloading device 18; some workpieces are directly transferred from the seventh exchange table 16 to the unloading device 18 through the second robot gripper device 20. The unloading device 18 is provided with a turnover pallet, and the pallet of the stacked finished workpieces is manually taken away as a whole and replaced with an empty pallet.
