[0001] The invention belongs to the technical field of welding, in particular to a welding device for producing electric hair dryers. Background Art

[0002] When welding the hair dryer's shift switch, a soldering machine is often used. The working principle of the soldering machine is to heat and melt the solid solder wire through an automatically heated soldering iron, and at the same time, with the help of flux, it flows between the metals to be welded, and forms a firm and reliable welding point after cooling.

[0003] Originally, the switch of the original hair dryer only had the function of on and off. When wiring the switch, there were only wirings at both ends. In the process of upgrading hair dryers, the function of switching various gears of the hair dryer appeared, including temperature gear and wind gear. Therefore, in the process of producing hair dryers, there may be multiple contacts for the hair dryer gear switch. The existence of multiple contacts is cumbersome to operate during welding. The common operation method is to manually take the gear switch and wire, and align the wiring position with the welding pen. Therefore, the present invention proposes a welding device that can target multiple contacts of the hair dryer gear switch. Summary of the invention

[0028] In this embodiment, a ring shaft 32 is rotatably mounted on the workbench 1, a rotating ring 3 is fixedly mounted on the ring shaft 32, 12 welding grooves 31 are opened on the rotating ring 3, and the welding grooves 31 are used to place the gear switch 5. The driving assembly 2 includes a first motor 21, a half gear 22, and a full gear ring 23. The first motor 21 is fixedly mounted on the workbench 1, and the output end of the first motor 21 is connected to the half gear 22. The full gear ring 23 is fixedly mounted on the ring shaft 32 in the circumferential direction, and the full gear ring 23 is meshed and connected with the half gear 22. The intermittent rotation of the rotating ring 3 is realized by the meshing connection between the half gear 22 and the full gear ring 23, that is, the rotating ring 3 rotates 30 degrees, stops for a period of time, and then continues to rotate 30 degrees, so that the switching of several welding grooves 31 can be realized;

[0029] The support frame 13 is L-shaped, and a first mounting frame 192 and a second mounting frame 193 are fixedly installed on the transverse part of the support frame 13. The threaded rod 19 passes through the first mounting frame 192 and the second mounting frame 193, and is rotatably connected to the first mounting frame 192 and the second mounting frame 193. A movable groove 131 is provided on the transverse part of the support frame 13, and the movable plate 9 is located in the movable groove 131 and is slidably connected to the movable groove 131. A sliding groove 91 is provided on the movable plate 9, and the other end of the first hinged rod 10 is located in the sliding groove 91 and is slidably connected to the sliding groove 91. One end of the second hinged rod 18 is rotatably connected to a driving block 102, and the driving block 102 is threadedly connected to the threaded rod 19.

[0030] When welding, firstly, the material is loaded through the first conveying assembly 14, and the gear switch 5 is loaded onto the welding groove 31. Then, through the rotation of the first motor 21, the welding groove 31 rotates to the position corresponding to the welding pen 8. At this time, the second motor 20 is started, and the first hinge rod 10 and the second hinge rod 18 are driven to rotate by the second motor 20. The welding pen 8 moves in the X direction and the Y direction until it is just located on one side of the terminal head 51 of the gear switch 5. Then, the terminal heads 51 on one side of the gear switch 5 are wired and welded. In this embodiment, there are 4 terminal heads 51 on one side. After the wiring welding is completed, the second motor 20 drives the threaded rod 19 to rotate in the opposite direction, so that the welding pen 8 moves away, and finally the welding pen 8 is located on one side of the gap between the adjacent terminal heads 51. At this time, the rotating ring 3 rotates again to switch the position. When the next gear switch is switched, the rotating ring 3 rotates again to switch the position. When welding, the gear switch 5 that has just been welded is located in the welding groove 31 corresponding to the telescopic member 12. The telescopic member 12 is started while the next gear switch 5 is being welded, and the gear switch 5 is pushed to the symmetrical welding groove 31 position by the telescopic member 12, and then the telescopic member 12 is withdrawn. At this time, during the intermittent rotation of the rotating ring 3, the other side terminal head 51 that has not completed the wiring welding will be located at the wiring welding station again, and then with the intermittent rotation of the rotating ring 3, the welding of the terminal heads 51 on both sides of the gear switch 5 can be achieved. After the welding of the terminal heads 51 on both sides is completed, the gear switch 5 is pushed to the position of the second conveying assembly 15 by the telescopic member 12, so that the welded gear switch 5 is transported by the second conveying assembly 15. The telescopic distance of the telescopic member 12 can be determined by machine vision to determine the wiring status of the gear switch 5, thereby determining the telescopic length.

[0031] In this embodiment, the symmetrical welding grooves 31 at the position of the telescopic member 12 are connected, so that the positions of the terminal heads 51 on both sides can be automatically switched by the action of the telescopic member 12, so that the terminal heads 51 on both sides of the shift switch 5 can be automatically welded, thereby eliminating the need to rotate the position of the shift switch 5. Secondly, the welding pen 8 is connected through the scissor-type structure, so that the welding pen 8 can give way and the terminal heads 51 can be moved away from and close to each other through the scissor-type structure.

[0032] See also Figure 1 , Figure 2 , Figure 3 In one embodiment, two straight baffles 42 are fixedly installed on the workbench 1 at the inner side of the rotating ring 3 , and the symmetrical welding grooves 31 on the rotating ring 3 are connected through the two straight baffles 42 .

[0033] In this embodiment, a fixed column 43 is fixedly installed on the workbench 1. The fixed column 43 is coaxially arranged with the rotating ring 3. The fixed column 43 is located on the inner side of the rotating ring 3. A fixed platform 4 is fixedly installed on the fixed column 43. Two straight baffles 42 are fixedly installed on the fixed platform 4. The distance between the straight baffles 42 is the same as the width of the welding groove 31.

[0034] By providing the straight stopper 42 , the telescopic trajectory of the telescopic member 12 can be restricted, thereby limiting the movement of the shift switch 5 .

[0035] See also Figure 1 , Figure 2 , Figure 3 In one embodiment, a ring baffle 41 is fixedly mounted on one side of the straight baffles 42 that is away from each other.

[0036] In this embodiment, by providing a ring baffle 41, the welding groove 31 at the position of the telescopic part 12 and the second transmission component 15 can be blocked, thereby preventing the gear switch 5 at the position of other welding grooves 31 from entering the axial position, that is, causing misalignment.

[0037] See also Figure 3 , Figure 4 In one embodiment, a spring 16 is installed on the support frame 13 at one side close to the rotating ring 3 , and an extrusion block 17 is fixedly installed on one end of the spring 16 away from the support frame 13 .

[0038] In this embodiment, the two ends of the gear switch 5 can be limited by the extrusion block 17 and the ring baffle 41. The gear switch 5 is squeezed and fixed by the extrusion block 17 when the rotating ring 3 is stationary, so that the terminal 51 corresponds to the position of the welding pen 8. When the rotating ring 3 rotates, the extrusion block 17 retracts to the outside of the rotating ring 3. When the welding groove 31 moves to the corresponding position of the extrusion block 17, the extrusion block 17 squeezes and fixes the gear switch 5 under the action of the spring 16.

[0039] See also Figure 4 In one embodiment, the extrusion block 17 is a right-angled trapezoidal structure.

[0040] In this embodiment, the extrusion block 17 is set to a right-angled trapezoidal structure, so that the inclined surface of the right-angled trapezoid corresponds to the rotation direction of the rotating ring 3. Therefore, when rotating, the rotating ring 3 is squeezed to the inclined surface direction of the extrusion block 17. At this time, the extrusion block 17 is driven to retract while rotating until the outer side surface of the rotating ring 3 contacts the top surface of the right-angled trapezoid. When the extrusion block 17 squeezes the gear switch 5, the right-angled side of the right-angled trapezoid contacts the side of the welding groove 31, thereby avoiding the reverse slipping of the rotating ring 3, thereby ensuring that the position of the terminal 51 corresponds to the welding pen 8.

[0041] See also Figure 5 , Figure 7 In one embodiment, it further includes a wire tube 6 , on which the support frame 13 is fixedly mounted a wire tube 6 corresponding to the terminal 51 on the gear switch 5 .

[0042] In this embodiment, the wire tube 6 is provided to limit the position of the live wire, so that the live wire can be automatically located at the position of the wiring head 51.

[0043] See also Figure 5 , Figure 7 In one embodiment, a movable tube 7 is slidably installed on the wire tube 6, and a bevel gear 72 is installed at one end of the movable tube 7 close to the gear switch 5. The movable tube 7 is transmission-connected to the second motor 20, and the second motor 20 is used to drive the bevel gear 72 to descend to clamp the live wire and to rise to release the clamping.

[0044] In this embodiment, the bevel teeth 72 are provided to clamp the wire. When the bevel teeth 72 descend, the bevel teeth 72 are contracted to provide a clamping force for the wire. When the bevel teeth 72 rise, the bevel teeth 72 spread out and cover the outer wall of the wire tube 6, thereby releasing the clamping.

[0045] See also Figure 8 , Fig. 9 In one embodiment, a driving disc 26 is fixedly mounted on the output end of the second motor 20, a toothless gear 28 is fixedly mounted on the driving disc 26, a plurality of fixed teeth 29 are circumferentially mounted on the driving disc 26, a main gear 191 is fixedly mounted on one end of the threaded rod 19, a third transmission gear 27 is rotatably mounted on the support frame 13, the main gear 191 is meshedly connected with the toothless gear 28, the third transmission gear 27 and the fixed teeth 29, racks 71 are fixedly mounted on both sides of the movable tube 7, the racks 71 are meshedly connected with the third transmission gear 27, and a plurality of the movable tubes 7 are transmission-connected.

[0046] In this embodiment, when the main gear 191 is engaged with the toothless gear 28, the threaded rod 19 drives the welding pen 8 to approach the terminal head 51, and at the same time, the movable tube 7 is driven to descend through the third transmission gear 27, that is, the bevel gear 72 clamps the live wire, and then the main gear 191 is disengaged from the toothless gear 28 and the fixed gear 29 at the same time, the welding pen 8 and the movable tube 7 remain stationary, and the welding action is performed at this time. When the welding is completed, when the main gear 191 is engaged with the fixed gear 29, the threaded rod 19 drives the welding pen 8 away from the terminal head 51 and gives way, and at the same time, the movable tube 7 is driven to rise through the third transmission gear 27, that is, the bevel gear 72 cancels the clamping of the live wire, completing a cycle, and when the main gear 191 is disengaged from the toothless gear 28 and the fixed gear 29 at the same time, the welding pen 8 and the movable tube 7 remain stationary.

[0047] The forward and reverse rotation structure in this embodiment can also use the reciprocating movement of the rack to achieve the forward and reverse rotation of the gear, and is not limited to the specific structure recorded in this embodiment.

[0048] See also Figure 8 In one embodiment, a first transmission gear 24 and a second transmission gear 25 are rotatably mounted on the support frame 13 , and the first transmission gear 24 and the second transmission gear 25 are respectively meshed and connected with the rack 71 on the adjacent movable tube 7 .

The transmission of the plurality of movable tubes 7 is realized through the first transmission gear 24 and the second transmission gear 25. The transmission can also be achieved by fixedly connecting the plurality of movable tubes 7 or by using belts.
