[0032] The gear feeding mechanism 2 includes a conveying track 21 for conveying the gear 7. The conveying track 21 is fixed on the frame 1. The upper end of the conveying track 21 forms a feeding end and is used to be connected to the vibrating loading plate. The lower end of the conveying track 21 forms a discharging end. The side wall of the conveying track 21 is movably provided with a first stopper 22 and a second stopper 23 distributed along the moving direction of the gear 7 and used to block the gear 7.

When the piston rod of the third cylinder 25 is contracted, the third cylinder 25 is used to drive the second stopper 23 to move so that the second stopper 23 Block 23 releases the obstruction to gear 7; after adopting this gear feeding mechanism, first, the piston rod of the second cylinder contracts, and at this time the first block can release the obstruction to the gear in the conveying track. Since the distance between the first block and the second block is greater than the outer diameter of a single gear and less than the sum of the outer diameters of the two gears, under the gravity of the gears in the conveying track, only one gear is allowed to enter the gap between the first block and the second block, and then the piston rod of the second cylinder extends, and at this time the first block can press the gear located at the first block, and then the piston rod of the third cylinder contracts, and at this time the second block can release the obstruction to the gear located in the gap between the first block and the second block, so that one of the gears located in the gap between the first block and the second block can be discharged through the conveying track and fall into the channel located on the bearing seat; by repeating the above process, the track assembly can intermittently feed the gears one by one into the channel located on the bearing seat.

[0033] The screw feeding mechanism 3 includes a material rack 31, a discharge track 32, a push plate 33 and a fourth cylinder 34.

The opening groove 322 is located below the storage chamber 311. The groove width of the opening groove 322 is smaller than the outer diameter of the screw 8. After adopting this screw feeding mechanism, when the piston rod of the fourth cylinder extends, the push plate can move to the right and into position. At this time, the push plate can move out from the material trough below the storage chamber from left to right. In this way, a screw located at the bottom of the storage chamber can fall into the material trough. When the piston rod of the fourth cylinder contracts, the push plate can move to the left and into position. At this time, the push plate can move to the material trough below the storage chamber. At the same time, a screw in the material trough below the storage chamber can be pushed out from the material trough below the storage chamber from right to left. By repeating the above steps, the screws in the storage chamber can be pushed out one by one to realize feeding of the screws one by one.

[0034] The screw feeding mechanism 3 also includes a fifth cylinder 35 and a limit block 36. The limit block 36 is arranged above the left side of the discharge track 32. The fifth cylinder 35 is fixed to the frame 1, and the limit block 36 is fixed to the piston rod of the fifth cylinder 35. When the piston rod of the fifth cylinder 35 is extended, the limit block 36 is used to move to the top of the material trough 321 and to prevent the screw 8 located in the material trough 321 from tilting. When the piston rod of the fifth cylinder 35 is retracted, the fifth cylinder 35 is used to drive the limit block 36 to move from front to back so that the limit block 36 is moved out from above the material trough 321. After adopting this structure, when the piston rod of the fifth cylinder is extended, the limit block can move to the top of the material trough. In this way, when the gear is screwed to the screw, the limit block can block the screw to avoid the screw in the material trough from tilting. When the piston rod of the fifth cylinder is retracted, the limit block can release the limit on the screw located in the material trough.

[0035] The discharging mechanism 5 comprises a rodless cylinder 51, a sixth cylinder 52 and a pneumatic clamp 53.

Subsequently, the piston rod of the sixth cylinder contracts to move the pneumatic clamp upward into place, and then the rodless cylinder drives the sixth cylinder to move the sixth cylinder forward into place, and then the piston rod of the sixth cylinder extends to move the pneumatic clamp downward into place, and then the pneumatic clamp can release the screwed gear and screw. At this time, the screwed gear and screw can fall into the lower hopper, and finally, the piston rod of the sixth cylinder contracts to move the pneumatic clamp upward and reset.

[0036] When the present invention is working, first, the gear feeding mechanism can convey a gear to the supporting seat so that the gear from the gear feeding mechanism can slide into the channel and the limit groove located on the supporting seat, and at the same time, the screw feeding mechanism can convey a screw to the screwing mechanism (after a screw is conveyed to the screwing mechanism, the piston rod of the fifth cylinder can extend, so that the limit block can move to the top of the material trough, so that when the subsequent gear and the screw are screwed together, the limit block can block the screw to avoid the material screw in the material trough from warping). Then, the linear drive structure drives the rotary drive structure to move the rotary drive structure and the supporting seat to the right into position. At this time, the left end of the screw from the screw feeding mechanism can be inserted into the channel from right to left, so that the left end of the screw from the screw feeding mechanism can pass through the threaded hole in the gear and make the threaded portion on the outer wall of the screw abut against the threaded hole in the gear. Then, the rotary drive structure drives The movable bearing seat and the gear located in the bearing seat rotate. When the gear rotates, the gear can be screwed onto the screw. After the rotation driving structure drives the bearing seat and the gear to rotate the set number of circles, the rotation driving structure stops working (because the rotation driving structure drives the rotating sleeve and the bearing seat to rotate by the servo motor, and the servo motor has the advantage of high positioning accuracy, so that after the rotation driving structure stops working, the channel located on the bearing seat can return to its initial angle), that is, the gear and the screw are screwed together (the gear and the screw are screwed together, and the piston rod of the fifth cylinder can be retracted, so that the limit block can release the limit on the screw located in the material trough), then, the discharging mechanism clamps the screwed gear and screw and places the screwed gear and screw into the lower hopper, finally, the linear drive structure drives the rotation driving structure to move the rotation driving structure and the bearing seat to the left and reset, after the above process, the screwing of the gear and the screw is completed.
