For products that fail the inspection, the control system controls the discharge device to send them to the corresponding waste discharge channel 18 for separate collection according to the reasons for their failure, so as to facilitate subsequent rework.

[0043] The plug receiving groove 31 is a vertical through-structure with an outer shape matching that of the plug. An arc-shaped plug supporting plate 29 is also fixedly provided on the frame 1. The plug supporting plate 29 can seal the lower side of the plug receiving groove 31 in the designated rotation area so that the plug can be stably accommodated in the plug receiving groove 31. The inner cover loading tray 4 is higher than the assembly cover tray 15, and the inner cover receiving groove 41 on the inner cover loading tray 4 can be vertically aligned with the second assembly cover receiving groove 151 on the assembly cover tray 15 when the inner cover loading tray 4 is rotated to the set position.

[0044] The discharging device includes a third manipulator 20, and the first manipulator 5, the second manipulator 6 and the third manipulator 20 respectively include a suction nozzle 22, a lifting bracket 23, a rotating disk 24 and a negative pressure providing device. The rotating disk 24 can be installed on the frame 1 to rotate around a vertical axis, wherein the rotating disks 24 of the first manipulator 5 and the second manipulator 6 are respectively coaxially fixedly connected to the plug feeding disk 3 and the cover assembly turntable, the grabbing disk of the third manipulator 20 is eccentrically arranged with the detection turntable 16, and a number of lifting brackets 23 are evenly spaced on the rotating disks 24 of the first manipulator 5, the second manipulator 6 and the third manipulator 20, each lifting bracket 23 can move up and down in the vertical direction, and the suction nozzle 22 is rotated. A corresponding one is fixedly installed at the lower end of each lifting bracket 23, and the suction nozzles 22 of the first manipulator 5 and the second manipulator 6 are respectively arranged one by one directly above the plug receiving groove 31 and the second group of cover receiving groove 151. The suction nozzles 22 of the first manipulator 5 and the second manipulator 6 can respectively negatively adsorb the plug supported by the plug supporting plate 29 and the inner cover in the inner cover receiving groove 41. The suction nozzle 22 of the third manipulator 20 can respectively reach the third group of cover receiving groove 161, different waste discharge channels 18 and finished product discharge channels 19 in the designated position on the detection turntable 16. The negative pressure providing device provides negative pressure to each suction nozzle 22, and the control system controls the operation of the negative pressure providing device.

[0045] When assembling the plug, the lifting bracket 23 of the first manipulator 5 first descends, so that the suction nozzle 22 on it sucks the plug held by the plug supporting plate 29 in the plug receiving groove 31, and then the lifting bracket 23 of the first manipulator 5 rises to lift the plug to a certain height. At the same time, after the plug rotates synchronously with the rotating disk 24 and the plug loading disk 3 by a certain angle, there is no plug supporting plate 29 blocking the bottom of the plug receiving groove 31, forming a vertical through structure. At this time, the lifting bracket 23 descends and the plug passes through the plug receiving groove 31 straight The rubber plug is then loaded into the outer cover just below the rubber plug receiving groove 31. Then, the suction nozzle 22 releases the rubber plug, and the lifting bracket 23 rises to a position above the rubber plug loading tray 3 to reset, waiting for the next rubber plug assembly. Since each rubber plug receiving groove 31, the outer cover receiving groove 21, and a lifting bracket 23 and the suction nozzle 22 thereon are arranged opposite each other, each rubber plug can be quickly loaded into the corresponding outer cover while the rubber plug loading tray 3, the outer cover loading tray 2 and the rotating disk 24 of the first manipulator 5 rotate synchronously, and the assembly efficiency is extremely high.

[0046] When assembling the inner cover, the lifting bracket 23 of the second manipulator 6 is lowered first, so that the suction nozzle 22 on it sucks the inner cover in the inner cover receiving groove 41 that is directly opposite to the second group cover receiving groove 151. Then the lifting bracket 23 of the second manipulator 6 rises to lift the inner cover to a certain height. At the same time, the inner cover is separated from the inner cover loading tray 4 after rotating synchronously with the rotating disk 24 and the group cover material tray 15 by a certain angle. At this time, the lifting bracket 23 descends and directly installs the inner cover into the outer cover in the second group cover receiving groove 151, pressing the rubber plug. Then, the suction nozzle 22 releases the inner cover, and the lifting bracket 23 rises to the inner cover. The height position above the loading tray 4 is reset, waiting for the next assembly of the inner cover. Since each second-group cover accommodating slot 151 is directly opposite to a lifting bracket 23 and the suction nozzle 22 thereon, and each inner cover accommodating slot 41 can be moved to directly above a second-group cover accommodating slot 151 when the inner cover loading tray 4 rotates to the set position, that is, directly opposite to the suction nozzle 22 below a lifting bracket 23, while the inner cover loading tray 4, the group cover tray 15 and the rotating disk 24 of the second manipulator 6 rotate synchronously, each inner cover is quickly loaded into the corresponding outer cover, thereby realizing the inner cover assembly with extremely high assembly efficiency.

[0047] During discharge, the lifting bracket 23 of the third manipulator 20 first descends, so that the suction nozzle 22 on it sucks the finished product in the third group cover accommodating groove 161 that is rotated to the specified position, and then the lifting bracket 23 of the third manipulator 20 rises to lift the finished product to a certain height. At the same time, the finished product rotates synchronously with the rotating disk 24 and the group cover material disk 15 at different angles, and then the finished product arrives just above the entrance of different waste discharge channels 18 or finished product discharge channels 19. The control system controls the suction nozzle 22 under the lifting bracket 23 to cut off the air according to the detection results of the detection camera 17, and then sends each finished product into the waste discharge channel 18 or the finished product discharge channel 19 to realize material collection.
