[0023] Referring to Figures 1-3 as shown, it is a preferred embodiment provided by the present invention.
[0024] The automatic welding structure of the silk thread and the ring includes positioning the head end of the silk thread 300 and allowing the ring 301 to be sleeved on the positioning shaft 400. The head end of the silk thread 300 has a head section, and the positioning shaft 400 has a limiting structure that restricts the relative fixation between the head section and the positioning shaft 400. When the ring 301 is sleeved on the positioning shaft 400, the ring 301 abuts against the head section; a welding device is provided on the outer side of the positioning shaft 400, and the welding device welds and fixedly connects the head section and the ring 301.
[0025] For the above-provided automatic welding structure of the silk thread and the ring, the limiting structure restricts the head section on the positioning shaft 400 and keeps it relatively fixed with the positioning shaft 400. After the ring 301 is sleeved on the positioning shaft 400, the ring 301 abuts against the head section, realizing the abutment positioning between the head section and the ring 301. The welding device automatically welds the relatively positioned ring 301 and the head section. The welding operation is simple and the welding efficiency is high.
[0026] In this embodiment, the limiting structure is arranged at the top of the positioning shaft 400. In this way, the head section is restricted at the top of the positioning shaft 400, which is convenient for the abutment positioning between the ring 301 and the head section after the ring 301 is sleeved on the positioning shaft 400.
[0027] In this embodiment, the limiting structure includes a recessed groove arranged at the top of the positioning shaft 400 and for the head section to be embedded in. The recessed groove penetrates through the end of the positioning shaft 400; when the lower part of the head section is embedded in the recessed groove, the upper part of the head section is exposed above the recessed groove, and the ring 301 abuts against the upper part of the head section.
[0028] By arranging the recessed groove, it is convenient for the head section to be embedded in the recessed groove, and the position between the head section and the positioning shaft 400 is relatively fixed, which is convenient for the positioning of the head section on the positioning shaft 400.
[0029] In this embodiment, the recessed groove is arranged in a straight line, which is convenient for the head section to be transmitted into the recessed groove.
[0030] The end of the positioning shaft 400 is in a conical head shape, which facilitates the sleeving of the ring 301 on the positioning shaft 400.
[0031] In this embodiment, a moving seat 200 is provided below the positioning shaft 400. The moving seat 200 drives the ring 301 to be sleeved on the positioning shaft 400 and drives the ring 301 to move downward so that the ring 301 abuts against the head section. After the ring 301 is loaded, it is fixed on the moving seat 200. When the head section is placed on the positioning shaft 400, the moving seat 200 moves, sleeving the ring 301 on the positioning shaft 400, and the moving seat 200 moves downward so that the ring 301 abuts against the head section and keeps the position of the ring 301 fixed without shaking.
[0032] Due to the function of the moving seat 200, during the welding of the head section and the ring 301 by the welder, the position of the ring 301 is kept fixed without shaking.
[0033] In this embodiment, the moving seat 200 is provided with a placement groove with an open top for placing the ring 301, and a vacuum suction port for sucking the circumferential side of the ring 301 is provided at the bottom of the placement groove. In this way, it is convenient to fix the ring 301 on the moving seat 200, and under the suction action of the vacuum suction port, the ring 301 can move synchronously with the moving seat 200.
[0034] In this embodiment, a pressing head 100 is provided at the top of the positioning shaft 400. After the ring 301 is sleeved on the positioning shaft 400, the pressing head 100 presses the ring 301 from top to bottom so that the ring 301 abuts against the head section relatively fixedly. In this way, the position between the ring 301 and the head section can be made stable after abutting, improving the abutting positioning between the head section and the ring 301, and facilitating the welding and fixing between the head section and the ring 301 by the welder.
[0035] In this embodiment, the bottom of the pressing head 100 has two pressing walls 102 arranged obliquely towards each other. Along the direction from top to bottom, the two pressing walls 102 are inclined away from each other; after the pressing head 100 moves downward, the two pressing walls 102 press against both sides of the ring 301.
[0036] By forming two pressing walls 102, it is convenient to symmetrically press both sides of the ring 301, keeping the force on the ring 301 balanced, so that the ring 301 is pressed and fixed in position with the head section.
[0037] In this embodiment, a bare empty area 101 through which the laser of the welder can pass is provided in the middle of the pressing head 100. The bare empty area 101 is arranged vertically aligned with the head section placed on the positioning shaft 400. In this way, when the pressing head 100 presses the ring 301 so that the ring 301 is relatively fixed to the head section, the laser emitted by the welder can pass through the bare empty area 101 to weld the head section and the ring 301.
[0038] In addition, after the head section and the ring 301 are welded, a weld scar will be formed, and the weld scar may stick to the positioning shaft 400. At this time, the moving seat 200 can be used to lift the ring 301 upwards so that the weld scar is separated from the positioning shaft 400.
[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
