[0028] The rotary assembly robot 3 is provided with a barcode scanner (not shown in the figure) for scanning the two-dimensional code of the torque converter 14 on the first alignment device 1 .

[0029] When the rotary assembly manipulator 3 assembles the torque converter 14, the servo reduction motor 27 rotates, driving the driving pulley 55 and the driven pulley 56 to rotate, and at the same time the lifting cylinder 34 pushes the second connecting plate 47 to rise and fall, so that the rotary assembly manipulator 3 rotates and assembles downward.

[0030] The transfer robot gripper 40 is used to clamp the outer periphery of the torque converter 14, and includes an air gripper 42, a mounting plate 46 and a clamping plate 24 arranged on the air gripper 42. The air gripper 42 is arranged on the mounting plate 46. A fourth switch bracket 44 is arranged on the mounting plate 46. A proximity switch 45 is arranged on the fourth switch bracket 44.

[0031] Working principle: The hydraulic torque converter 14 is placed on the tray 8 with the shaft head facing downward, and the tray 8 drives the hydraulic torque converter 14 to run to the loading station.

[0032] The transfer robot gripper 40 opens and moves to the torque converter 14, controls the transfer robot gripper 40 to clamp the torque converter 14 and moves it to above the oil receiving pan 25, and rotates the torque converter 14 180° to control the oil.

[0033] After the oil control of the torque converter 14 is completed, it is detected whether there is the torque converter 14 on the first alignment device 1. If not, the transfer robot gripper 40 places the torque converter 14 on the first alignment device 1. Otherwise, the transfer robot gripper 40 places the torque converter 14 on the cache table 5. When it is detected that there is no torque converter 14 on the first alignment device 1, the torque converter 14 on the cache table 5 is moved to the first alignment device 1.

[0034] The gearbox 26 is placed on the gearbox conveyor line body 50, and the gearbox 26 is conveyed to the bottom of the second alignment device 2. The first lifting device 6 drives the second alignment device 2 to move downward, and the second alignment device 2 is rotated to preliminarily align the position of the square key 60 of the gearbox 26. After alignment, the first lifting device 6 moves upward back to its original position.

[0035] The adjusted gearbox 26 moves to the assembly position along with the gearbox conveyor line 50, and the lateral movement device 9 drives the rotary assembly manipulator 3 to move toward the first alignment device 1. After reaching the top of the first alignment device 1, the barcode scanner on the rotary assembly manipulator 3 automatically scans the QR code of the hydraulic torque converter 14 on the first alignment device 1. After the barcode is successfully scanned, the rotary assembly manipulator 3 moves downward to clamp the hydraulic torque converter 14 on the first alignment device 1. If the code scanning is unsuccessful, the transverse movement device 9 drives the rotary assembly robot 3 to return to the assembly position, the transfer robot gripper 40 opens, clamps the torque converter 14 that has not been successfully scanned, and moves to the top of the oil receiving pan 25. The transfer robot gripper 40 rotates the torque converter 14 180°, places the torque converter 14 on the unqualified material channel 54, and then re-clamps the torque converter 14 from the buffer table 5 and moves it to the first alignment device 1 for scanning again.

[0036] The lateral movement device 9 drives the rotary assembly manipulator 3 and the torque converter 14 to move toward the adjusted gearbox 26, and the rotary assembly manipulator 3 drives the torque converter 14 to move downward and rotate, and docks with the first spline 58 of the gearbox 26. After docking, it docks with the second spline 59 of the gearbox 26, and docks with the square key 60 of the gearbox 26 after successful docking, until the first spline 58, the second spline 59 and the square key 60 of the gearbox 26 and the torque converter 14 are all assembled in place, and the assembled gearbox 26 and the torque converter 14 are transported to the designated qualified product position with the gearbox conveyor line body 50, and the rotary assembly manipulator 3 moves upward to the original position at the same time. If any spline or square key 60 is not assembled in place, the subsequent spline or square key 60 will not be assembled, and the rotary assembly manipulator 3 moves upward to the original position, and the gearbox 26 and the torque converter 14 are transported to the designated unqualified product position with the gearbox conveyor line body 50.

[0037] The present invention places the torque converter 14 on the tray 8 with the shaft head facing downward, which is consistent with the incoming packaging direction of the torque converter 14, thus avoiding manual flipping of the torque converter 14. It is only necessary to manually load the torque converter 14 onto the tray 8, which greatly reduces the labor intensity of the operator. A transfer robot gripper 40 and an oil receiving pan 25 are provided. The transfer robot gripper 40 grips the torque converter 14 to control the oil, which can reduce the work intensity caused by manual oil control. The oil receiving pan 25 prevents the oil from dripping onto the ground. At the same time, the oil receiving pan 25 can collect and filter the oil for reuse, thereby reducing the cost of the gearbox oil. The hydraulic torque converter 14 is installed on the tray 8, with the shaft head facing downward and the oil port facing upward, thus avoiding the situation of oil dripping downward in the traditional assembly oil port direction and reducing safety hazards; The delivery of the hydraulic torque converter 14 and the assembly of the hydraulic torque converter 14 are carried out simultaneously, so the production efficiency is improved; A detachable quick-change head 13 is provided on the tray 8. When the torque converter 14 needs to be replaced, only the quick-change head 13 needs to be replaced, and the replacement is fast. The transfer robot gripper 40 grips the outer periphery of the torque converter 14, replacing the traditional gripper to grip the shaft head position, and is compatible with more types of torque converters 14, avoiding changes in the structure and size of the shaft head of the torque converter 14, resulting in frequent replacement of the gripper, increasing the cost of gripper manufacturing, and increasing the time for gripper replacement, resulting in waste of production capacity.
