Figure 1 and Figure 5 It is understood that one end of the screw rod 14 is connected to the motor drive mechanism in the prior art. After the metal dial 9 to be welded falls onto the position control disk 4, the motor drive mechanism controls the rotation of the screw rod 14, and then sends the position control disk 4 to the bottom of the welding robot 2. After the welding work is completed, the screw rod 14 reverses, and then the position control disk 4 drives the metal dial 9 to move out of the work station box 1.

[0032] The control disk component 4 includes a feeding assembly 16, an upper disk assembly 17 and a lower disk assembly 18. The lower disk assembly 18 is arranged below the upper disk assembly 17.

The control disk 4 moves out of the work station box 1, and the U-shaped frame 22 is intercepted by the V-shaped long plate 8 on its travel route. Figure 7 and Figure 9 It is understood that the V-shaped long plate 8 hooks the U-shaped frame 22, and the U-shaped frame 22 moves to drive the inner gear ring 20 to rotate. After the V-shaped long plate 8 no longer hooks the U-shaped frame 22, the first spring 25 supports and controls the L-shaped control plate 24, and then drives the L-shaped control column 23. The L-shaped control column 23 hooks the U-shaped frame 22, so that the U-shaped frame 22 is automatically reset, so that the inner gear ring 20 is reversed and reset. Figure 7 The reset status is shown.

An L-shaped support frame 27 is fixedly connected between the upper ring piece 33 and the arc-shaped rail 28. One side of the ring piece 33 is fixedly connected to a Z-shaped control plate 34, and one side of the Z-shaped control plate 34 is fixedly connected to a slider 15. A plurality of evenly distributed unit components 29 are provided on the upper ring piece 33, and a support component 32 is provided on one side of each unit component 29. The bottom end of the support component 32 is transmission-connected to the inner gear ring 20. The support component 32 and the unit component 29 cooperate to clamp the metal dial 9. One end of the unit component 29 is in contact with the arc-shaped support plate 30, and one side of the outer gear ring 31 is meshingly transmission-connected to the disc gear 10. Figure 8 It is understood that the disc gear 10 rotates to control the outer ring gear 31, and the rotation of the outer ring gear 31 drives the arc-shaped support plate 30, and the arc-shaped support plate 30 moves around to support the unit assembly 29, triggering the unit assembly 29 to deform.

[0035] The supporting assembly 32 includes a fan-shaped plate 35, a short shaft 36 and a blade plate 37. The short shaft 36 passes through one end of the blade plate 37. The bottom end of the short shaft 36 is meshed with the inner ring gear 20 by setting a shaft gear. The top end of the short shaft 36 is connected to the fan-shaped plate 35. The fan-shaped plate 35 is fixed on the upper ring plate 33, and the short shaft 36 is movably sleeved in the through hole opened on the fan-shaped plate 35.

[0036] The unit assembly 29 includes a frame plate 38, a locking seat 39, a second spring 40, an intercepting plate 41 and an inner column 42. One side of the locking seat 39 contacts the frame plate 38. The upper end of the frame plate 38 is fixed on the upper ring plate 33. The bottom end of the frame plate 38 is fixedly connected to the inner column 42. The second spring 40 is sleeved on the inner column 42. The second spring 40 is supported between the intercepting plate 41 and the frame plate 38. The inner column 42 is movably sleeved in the through hole opened on the intercepting plate 41.

[0037] The card seat 39 includes a rubber tube 43, a closed loop frame 44, a positioning screw 45, a door-shaped folding plate 46, a T-shaped column 47, a third spring 48 and an inner slide 49. The inner slide 49 is slidably provided in the door-shaped folding plate 46. A square hole is provided on the inner slide 49. The T-shaped column 47 is movable through the through hole provided on the inner slide 49. One end of the T-shaped column 47 is fixed on the door-shaped folding plate 46, and the other end of the T-shaped column 47 extends into the square hole of the inner slide 49. A door-shaped folding plate 46 and the inner slide 49 are provided between them. There is a third spring 48, which is sleeved on the T-shaped column 47. The intercepting plate 41 is fixed to one side of the inner slide 49. A slope is set on one side of the door-shaped folding plate 46. A closed-loop frame 44 is set above the slope of the door-shaped folding plate 46. A rod on one side of the closed-loop frame 44 is movable through the through hole opened on the door-shaped folding plate 46. A rubber tube 43 is fixed on the rod on the other side of the closed-loop frame 44. A positioning screw 45 is screwed on the door-shaped folding plate 46. One end of the positioning screw 45 supports the closed-loop frame 44. Figures 10 to 13 It is understood that during the circumferential movement of the arc-shaped support plate 30, the arc-shaped support plate 30 gradually supports the inner slide plate 49, and the inner slide plate 49 moves to control the door-shaped folding plate 46. The inclined end of the door-shaped folding plate 46 is close to the outer edge of the metal dial 9. In this way, multiple ring-distributed door-shaped folding plates 46 cooperate to clamp the metal dial 9, so that the metal dial 9 has a tendency to move downward, and the bottom of the metal dial 9 is intercepted by the blade 37, so that the metal dial 9 is limited in space. In addition, the rubber tube 43 moves with the door-shaped folding plate 46, and then presses on the upper surface of the edge of the metal dial 9 to prevent the metal dial 9 from rotating in place, thereby ensuring that the metal dial 9 is stable and motionless when being welded.

[0038] The welding device is set on the watch processing production line path, and the metal dial 9 to be welded is sent to the upper plate assembly 17 through the conveying mechanism, and then the metal dial 9 falls and is intercepted by a plurality of ring-arranged blades 37. The upper plate assembly 17 moves toward the inside of the work station box 1 in the following process: the screw 14 rotates to cause the slider 15 to move, and the slider 15 drives the support plate frame 11, thereby controlling the movement of the disc gear 10. The disc gear 10 is controlled by the spur rack 6, and the disc gear 10 rotates continuously. The transmission process of the disc gear 10 controls the outer gear ring 31 to rotate, and enters to trigger the automatic deformation in the upper plate assembly 17. In this way, when the metal dial 9 is sent to the bottom of the welding robot 2, the metal dial 9 has been The unit assembly 29 and the supporting assembly 32 cooperate to limit the position. After the metal dial 9 completes the welding work, the screw 14 rotates in the opposite direction, so that the upper plate assembly 17 automatically deforms in the reverse direction, and the metal dial 9 is only held at the bottom by multiple blades 37. When the upper plate assembly 17 moves to the outside of the work station box 1, it continues to move, and the U-shaped frame 22 will be hooked by the stationary V-shaped long plate 8. In this way, the U-shaped frame 22 rotates to drive the inner ring gear 20, and the inner ring gear 20 drives all the short shafts 36. The short shafts 36 control the rotation of the blades 37, and all the blades 37 move away from each other. In this way, the metal dial 9 falls from between the ring-arranged blades 37. After the metal dial 9 falls, it is sent away by the conveying mechanism on the production line.

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
