By adopting the above structure, the turntable component 1 does not need to stay at the loading station F1 when receiving the button unit 9, and the welding component 2 can move downward to weld the button unit 9, thereby achieving the loading and welding actions in the rotating state, thereby saving welding time and improving the welding efficiency of buttons.

[0046] See also Fig.10 As shown, the turntable assembly 1 includes a loading station F1, which is suitable for receiving the button unit 9; and an unloading station F2, which is suitable for discharging the button unit 9 after welding from the turntable assembly 1; wherein the welding assembly 2 is located at the first position at both the loading station F1 and the unloading station F2, so that the welding assembly 2 is away from the button unit 9, thereby facilitating the receiving and discharging of the button unit 9.

[0047] See also Figure 4 , Figure 5 and Figure 7As shown, in this embodiment, the turntable assembly 1 includes a welding turntable 11, and the peripheral edge of the welding turntable 11 is configured with a plurality of material receiving structures suitable for receiving the button unit 9, and the welding assembly 2 is configured above the material receiving structure. For details, refer to Figure 5 As shown, the material receiving structure is a material receiving groove 11a with a single-side opening, and the bottom of the material receiving groove 11a is provided with a groove adapted to the lower end surface of the panel 92 of the button unit 9, so that the button unit 9 can be located at the center of the material receiving groove 11a, so that the welding component 2 can accurately press against the button unit 9 when moving downward, thereby ensuring the welding quality of the button unit 9. Further, the turntable assembly 1 also includes a rotating disk body extending upward, and the outer side of the rotating disk body is penetrated by a mounting groove 11b, the number of the mounting grooves 11b is the same as the number of the material receiving grooves 11a and corresponds to one another, and the welding component 2 is movably arranged in the mounting groove 11b to improve the stability of the welding component 2 when moving up and down; in addition, the mounting groove 11b can also play a positioning and guiding role, so that the welding component 2 and the button unit 9 are more accurately combined, thereby improving the welding quality of the button unit 9.

Further, it also includes a PLC operation panel 92, which has a built-in PLC controller to improve the automation degree of the welding device 100.

[0049] See also Figure 1-Figure 4As shown, in this embodiment, the actuating assembly 3 includes a top plate 32 and an actuating member 31, the lower end surface of the top plate 32 is surrounded by four support columns 33 fixed on the frame 8, the four support columns 33 surround the periphery of the welding turntable 11, and the actuating member 31 is fixedly installed on the lower end surface of the top plate 32 so that the actuating member 31 is arranged above the turntable assembly 1; wherein the actuating member 31 has a retaining surface 31a and an actuating surface 31b protruding downward relative to the retaining surface 31a, the retaining surface 31a is configured to enable the welding member to be maintained at the first position, and the actuating surface 31b is configured to enable the welding member to move from the first position to the second position and maintain it at the second position. In this embodiment, the actuator 31 is a cylindrical cam, and the axis of the cylindrical cam coincides with the axis of the welding turntable 11. By adopting the cylindrical cam as the actuator 31, the welding component 2 can move up and down between the first position and the second position under the guidance of the retaining surface 31a and the actuating surface 31b when following the rotation of the turntable component 1, so as to move away from or engage with the button unit 9.

[0050] See also Figure 7-9 As shown, in this embodiment, the welding assembly 2 includes a welding column 21, a welding head 22 and an elastic member 23. The welding column 21 can be attached to the turntable assembly 1 in an upward and downward manner. Specifically, a mounting sleeve 24 is arranged in the mounting groove 11b of the welding turntable 11. The welding column 21 is installed in the mounting sleeve 24. The welding head 22 is screwed on the lower end surface of the welding column 21, and the lower end of the welding head 22 defines a welding end portion 22a suitable for positioning the button unit 9. For details, see Fig. 9 As shown, the center of the welding end 22a has a through hole for the tube body of the pin 91 to pass through and a concave-convex surface for welding the panel 92, so that when the welding column 21 moves downward, the pin 91 can be located at the center of the panel 92, and the two are welded together, thereby improving the welding quality of the button unit 9; in addition, it should be noted that a heating element is arranged in the welding column 21, which can generate heat to make the welding head 22 heat up, so as to weld the panel 92. The heating element can be a commercially available PTC heating tube, etc.; the elastic member 23 is configured to make the welding column 21 abut against the direction of the actuating component 3 to apply force to the welding column 21, and the elastic member 23 can be a compression spring, which is sleeved on the welding column 21 and is located between the mounting sleeve 24 and the upper end of the welding column 21, so that the upper end of the welding column 21 can always abut against the actuating component 3, thereby ensuring the accuracy of the up and down movement of the welding column 21.

[0051] In addition, the upper end of the welding assembly 2 also has a roller 4 that can be rotatably pressed against the actuator 31. Specifically, the roller 4 is installed at the upper end of the welding column 21. By providing the roller 4, the resistance between the welding column 21 and the actuator 31 can be reduced, so that the welding column 21 can rotate more smoothly around the actuator 31. Furthermore, a guide structure for guiding the welding assembly 2 to move up and down is also configured between the turntable assembly 1 and the welding assembly 2 to further improve the stability of the movement of the welding assembly 2, see Figure 7 As shown, the guide structure includes: a plurality of guide grooves 5 arranged along the circumferential direction of the welding turntable 11, any one of the guide grooves 5 is extended along the height direction, one end of the wheel axle 41 of the roller 4 extends toward the guide groove 5 to be embedded in the guide groove 5, and the roller 4 is limited by the guide groove 5, thereby reducing the displacement of the compression spring during the compression process, so that the compression spring is more stably compressed along the axial direction, thereby improving the stability of the overall movement of the welding column 21.

[0052] See also Figure 2 , Figure 3 , Figure 7 and Fig.10 As shown, it also includes a material unloading assembly 6, which is configured to be able to move the welded button unit 9 out of the turntable assembly 1 at the unloading station F2 to achieve unloading. Further, the material unloading assembly 6 includes a material unloading stopper 63, and the material unloading stopper 63 has an extension portion 631 extending toward one side of the turntable assembly 1, and the extension portion 631 is configured to be able to limit the button unit 9 from rotating with the turntable assembly 1, so that the button unit 9 falls at the unloading station F2, thereby being moved out of the turntable assembly 1. In the present embodiment, the unloading assembly 6 also includes an unloading cover 62 and an unloading stopper 61. The unloading cover 62 is arranged on the outer side of the circumferential outer edge of the welding turntable 11, and the unloading stopper 61 and the unloading stopper 63 are located on both sides of the unloading cover 62. Since the welding assembly 2 will gradually move from the second position to the first position near the unloading station F2, the button units 9 in this area lack enclosures, which can easily cause the button units 9 to be thrown out. If the upward movement of the welding assembly 2 is delayed, the welding joint 22 of the welding assembly 2 can easily collide with the unloading stopper 63. Therefore, a unloading stopper 61 is provided on the upstream side of the receiving cover (based on the rotation direction, the welding turntable 11 rotates in a clockwise direction in the present embodiment), so as to prevent the button units 9 in the receiving trough 11a from being thrown out, and then block them through the unloading stopper 63, so that the button units 9 are discharged through the unloading cover 62, which is convenient for collecting the button units 9 after welding.

[0053] See also Figure 1As shown, the utility model also provides a button production system, including the button welding device 100 as described above. By adopting the welding device 100, the overall automation level of the button production system is improved, and the production quality of buttons is improved.

[0054] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
