Both ends of the servo module 4 are arranged in the mounting openings 12. The servo module 4 is used to drive the first support seat 5 to move horizontally to change the position of the sleeve bin.

[0027] See Figure 3-4 Specifically, the lifting assembly 61 includes a connecting back plate 611 and a lifting cylinder 613. The connecting back plate 611 is connected to the first support seat 5. A travel groove 612 is provided on the connecting back plate 611. The bottom of the lifting cylinder 613 is connected to the body warehouse 1. A slider 614 is connected to the back of the sleeve warehouse 51. The slider 614 passes through the travel groove 612 and is slidably connected to the travel groove 612. The slider 614 is located above the output shaft of the lifting cylinder 613.

[0028] See Figure 4 Specifically, a slide rail 615 is provided on the connecting back plate 611 close to the side of the sleeve silo 51, and a slide block 511 is provided on the back of the sleeve silo 51. The slide rail 615 and the slide block 511 are connected by sliding.

[0029] See Figure 4 Specifically, the grabbing assembly 62 includes an air gripper 621 and a corresponding optical fiber 623. The air gripper 621 is arranged on the sleeve silo back plate 622. The sleeve silo back plate 622 is fixedly connected to the sleeve silo 51. Connecting platforms 624 are provided on both sides of the sleeve silo 51. The corresponding optical fiber 623 is arranged on the connecting platform 624.

[0030] See Figure 5-6 Specifically, the sleeve changing mechanism 8 includes a guide column cylinder 81, a second air gripper 83 and a clamp 84. The guide column cylinder 81 is arranged on the side of the component mounting plate 7, and the second air gripper 83 is arranged on the upper part of the component mounting plate 7. The output end of the guide column cylinder 81 is connected to the placement plate 82, and the placement plate 82 is provided with a second ring 86. The clamp 84 is provided with a first ring 85, and the first ring 85 is located above the second ring 86. The second air gripper 83 is used to grasp the tightening gun 9. The guide column cylinder 81 drives the second ring 86 to move accordingly by retracting or extending, so as to remove or lock the sleeve from the tightening gun 9.

[0031] See Figure 5-6 Specifically, both sides of the clamp 84 are provided with a second optical fiber 841, the back of the clamp 84 is provided with a proximity sensor 842, the sensing end of the proximity sensor 842 is close to the ring 1 85, the clamp (84) is provided with a magnet 843, and the second optical fiber 841 is used for tightening the gun 9 to find the sleeve angle.

[0032] The working principle of the present invention is as follows: first, the tightening gun 9 is manually pushed into the fixture 84, and the position of the tightening gun 9 is stabilized by the suction force of the magnet 843; the proximity sensor 842 senses the ring 1 85, thereby determining that the tightening gun is in place, and the air claw 2 83 approaches and clamps the tightening gun, so that the tightening gun 9 is stable, and the gun head of the tightening gun 9 extends into the ring 2 86, and the tightening gun 9 starts and rotates until the corresponding optical fiber 2 841 set on the fixture 4 has a signal, and the tightening gun 9 stops rotating. At this time, it is considered that the sleeve angle is found, and the tightening gun stops rotating. Then the servo motor 41 is started, and the first support seat 5 is driven to move horizontally through the servo module 4, and the sleeve bin 51 is driven to move synchronously, and then the idle sleeve bin 51 is transferred to the bottom of the tightening gun 9. At this time, the slider 614 connected to the sleeve bin 51 moves to the top Above the lifting cylinder 613, the air claw 1 621 is started to clamp the sleeve, and the guide column cylinder 81 contracts, driving the placement plate 82 and the second ring 86 to lift up, so that the sleeve is separated from the tightening gun 9. At the same time, the lifting cylinder 613 rises, pushing the slider 614 to rise along the stroke groove 612, driving the sleeve silo 51 to rise, and the sleeve enters the sleeve silo 51. Then the lifting cylinder 613 lowers the sleeve silo 51 to return to its position, and then the sleeve silo 51 containing the required sleeve is moved to the bottom of the tightening gun 9. The lifting cylinder 613 is then pushed out to lift the sleeve silo 51 containing the required sleeve, and the sleeve is sent to the head of the tightening gun 9. The guide column cylinder 81 extends out, driving the second ring 86 to lock the sleeve, the air claw 1 621 loosens the sleeve, and the air claw 2 83 loosens the tightening gun 9. The tightening gun 9 is pulled out manually, and the sleeve is replaced.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
