Description

Technical Field

[0001] The invention relates to the technical field of electronic component manufacturing equipment, in particular to a positioning spot welding machine for manufacturing electronic components. Background Art

[0002] Spot welding machine is a welding device used for connecting metal parts, which is widely used in metal processing, hardware and household appliances, automobile manufacturing, building steel structure, shipbuilding and other industries. Spot welding machine heats the metal parts to be connected to a molten state by converting electrical energy into thermal energy, thereby achieving connection between metal parts.

[0003] When welding electronic components, traditional spot welding machines often face problems such as inaccurate positioning, poor adaptability, complex operation and low production efficiency. The existence of these problems not only affects the welding quality, but also limits the improvement of production efficiency and capacity. Specifically, when welding ring-shaped electronic components, traditional spot welding machines lack an effective positioning mechanism, making it difficult to ensure that the center axis of the electronic components is aligned with the center axis of the welding equipment, resulting in low welding accuracy. In addition, due to the design limitations of the equipment, these spot welding machines are often only suitable for electronic components of a specific diameter or shape, and additional adjustments or replacement of equipment are required for electronic components of different specifications, which undoubtedly increases production costs and operating difficulties. Furthermore, many traditional spot welding machines require a lot of manual adjustments and monitoring during operation, and the degree of automation is not high, which not only affects production efficiency, but also increases the workload of operators. At the same time, if the smoke generated during welding is not effectively controlled, it will also have an adverse effect on the working environment and product quality. Summary of the invention

[0014] The present invention provides a positioning spot welding machine for manufacturing electronic components. It has the following beneficial effects: 1. The positioning spot welding machine for manufacturing electronic components can make the circular ring composed of the plug-in rod and the plug-in tube shrink synchronously through the mutual cooperation of the plug-in rod and the plug-in tube, so that the four covering plates can move inward at the same time, and through the limitation of the plug-in rod and the plug-in tube, the four covering plates can move with the same amplitude, so that the inner surface of the covering plate and the outer surface of the annular electronic component are finally firmly fitted, and the central axis of the annular electronic component is made to be the same as the central axis of the central tube, so as to realize the positioning of the annular electronic component, thereby facilitating the accuracy of subsequent welding, and through the mutual cooperation between the covering plate and the plug-in rod and the plug-in tube, the central axis of the electronic component is automatically positioned when the covering plate shrinks, which greatly improves the accuracy of welding, and the setting during shrinkage can also make the spot welding machine adapt to the welding requirements of annular electronic components of different diameters, greatly improving the scope of application of the spot welding machine and greatly improving its practicality.

[0015] 2.

After the welding is completed, the top plate moves up, and the pressure plate is reset under the action of elastic force, so that the corrugated plate loses the squeezing force and drives the sliding rod to drive the covering plate to reset, thereby releasing the annular electronic components, making the fixing and releasing of the electronic components fully automated, further improving the production efficiency, and facilitating the welding of the next electronic component.

[0016] 3. The positioning spot welding machine manufactured by the electronic component will also cause itself to contract when the elastic telescopic rod squeezes the push plate, and then the internal air pressure is transmitted to the second telescopic rod, prompting the second telescopic rod to extend downward, so that the welding head at the end of the second telescopic rod contacts the welding point on the upper surface of the annular electronic component, thereby cooperating with the first telescopic rod to instantly complete the welding of the electronic component, thereby achieving the effect of integration from fixation to welding. After the electronic component is positioned and fixed, welding is automatically realized immediately, further improving production efficiency, production capacity and accuracy. During the welding process, the internal air pressure of the bellows will also be transmitted outward through the lead-out hole on the mounting column, and then when the pressure plate is reset, the inside of the bellows is in a negative pressure state, thereby extracting air pressure inward through the connecting hole and the absorption hole, thereby achieving a suction force on the air near the welding point through the absorption hole when the spot welder is reset after welding, thereby effectively absorbing the smoke generated by welding, thereby not only preventing air pollution, but also improving the operator's field of vision, timely checking the welding quality, and greatly improving the welding quality.

The setting during contraction can also make this spot welding machine adapt to the welding requirements of annular electronic components of different diameters, greatly improving the scope of application of this spot welding machine and greatly improving its practicality.

[0024] Second embodiment: Figures 1 to 8 As shown, the bottom of the slide rod 77 is slidably connected to an auxiliary rod 713, the auxiliary rod 713 is set as a U-shaped rod, the inner end of the auxiliary rod 713 is fixedly connected to the middle side surface of the mounting column 71, and the top outer surface of the auxiliary rod 713 is fixedly sleeved with a drive ring 714, which is fitted on the bottom surface of the guide rod 74.

When the elastic telescopic rod 722 squeezes the push plate 716, it will also cause itself to contract, and then transmit its internal air pressure to the second telescopic rod 85, prompting the second telescopic rod 85 to stretch downward, so that the welding head at the end of the second telescopic rod 85 contacts the welding point on the upper surface of the annular electronic component, thereby cooperating with the first telescopic rod 84 to instantly complete the electronic component. The welding of parts is realized, thereby realizing the integrated effect from fixation to welding. After the electronic components are positioned and fixed, welding is automatically realized immediately, further improving production efficiency, capacity and accuracy. During the welding process, the internal air pressure of the bellows 81 will be transmitted outward through the outlet hole 87 on the mounting column 71, and then when the pressure plate 717 is reset, the inside of the bellows 81 is in a negative pressure state, thereby drawing air pressure inward through the connecting hole 86 and the absorption hole 88, and then when the spot welder is reset after welding, a suction force is generated on the air near the welding point through the absorption hole 88, thereby effectively absorbing the smoke generated by welding, which can not only prevent air pollution, but also improve the operator's field of vision, check the welding quality in time, and greatly improve the welding quality.
