Description

Technical Field

[0001] The utility model belongs to the technical field of welding, in particular to a semi-automatic micro-spot welding machine. Background Art

[0002] A micro-spot welder is a compact, lightweight, and highly efficient resistance welding device. The following is a detailed introduction to micro-spot welders: They utilize the electrothermal effect to convert electrical energy into heat, thereby achieving the desired weld quality. Specifically, they transfer current through electrodes to the workpiece, forming an arc. The high temperature of the arc melts the metal locally, which then cools and solidifies, achieving the weld. During the welding process, parameters such as power supply, current control, electrode contact, heat transfer, melting and cooling, and pressure control are precisely controlled to ensure weld quality and effectiveness.

[0003] Poor material clamping effect and insufficient clamping force: When the semi-automatic micro-spot welding machine clamps the material, the design or strength of the clamping mechanism may cause the material to loosen or shift during the welding process. This situation will affect the accuracy and stability of the welding and may even cause welding failure. Improper clamping method: Different materials require different clamping methods. If the clamping method is improper, the material may be deformed or damaged during the welding process. For example, for thin plate materials, a more sophisticated clamping mechanism may be required to avoid deformation caused by excessive pressure. The welding wire is not pulled smoothly, and the wire pulling mechanism design defects: When the semi-automatic micro-spot welding machine pulls the welding wire, if the pulling mechanism is not designed reasonably, the wire may be stuck or twisted during the pulling process. This situation increases the risk of wire breakage and affects the continuity and quality of the welding. The wire material and pulling speed do not match: Different welding wires have different hardness and toughness. If the pulling speed is too fast or too slow, the wire may not be able to adapt to the pulling force and break. Therefore, it is necessary to select a suitable pulling speed according to the material and characteristics of the wire. The substrate movement is not efficient and the moving mechanism design is unreasonable: Semi-automatic When the micro-spot welder moves the substrate, if the design of the moving mechanism is unreasonable or the accuracy is insufficient, the substrate may deviate or jitter during the movement. This will affect the accuracy and stability of welding and may even cause the welding position to deviate from expectations. The control system responds slowly: If the control system of the semi-automatic micro-spot welder responds slowly, the substrate may not be able to respond to instructions in time during movement, resulting in lag or overshoot, which will also affect the accuracy and efficiency of welding. The welding accuracy is poor, and comprehensive factors affect the above-mentioned poor material clamping effect, uneven welding wire traction, and inefficient substrate movement. These problems will all affect the welding accuracy. For example, loose or shifted material clamping will cause deviation of the welding position; wire breakage will cause welding interruption; deviation or jitter of the substrate movement will affect the accuracy and stability of welding. Equipment aging or wear: As the use time increases, some parts of the semi-automatic micro-spot welder may age or wear, thereby affecting its accuracy and performance. For example, wear of the clamping mechanism may result in insufficient clamping force; wear of the traction mechanism may result in uneven wire traction; wear of the moving mechanism may result in inaccurate substrate movement.

[0036] Example 1

The longitudinal screw rod 2012 is fixedly set at the output end of the longitudinal motor 204, and the moving block 2010 is threadedly connected to the outer wall of one end of the longitudinal screw rod 2012. The moving block 2010 is fixedly set at one side of the outer wall of the longitudinal plate 205.

This design allows the moving plate 201 and the components thereon (such as the moving platform 2) to achieve precise and smooth movement in the vertical direction, providing a high degree of flexibility for the welding operation. The transverse rod 209 is embedded in the inner wall slot of the limit platform 206 through a clamp, so that the moving component can also achieve stable movement in the horizontal direction, further enhancing the accuracy of the welding operation. Stable support and limit protection: The chassis 207 is fixedly arranged at the bottom of the outer wall of the moving plate 201, providing stable support for the entire moving component, ensuring stability and safety during the welding process.

Modular design and easy maintenance: the various components of the mobile component (such as the mobile plate 201, the longitudinal plate 205, the side rod 208, etc.) are combined together through guide rails, clamps and other connection methods to form a modular design. This design makes it easy to disassemble and replace the various components, reducing maintenance costs and time.

The chuck 3 is fixedly arranged at the top of the outer wall of the moving platform 2, and the limit rod 302 is fixedly arranged at the bottom of the outer wall of the constraint plate 301. The limiting rod 302 is embedded in the interior of the chuck 3, the spring sleeve 305 is sleeved on the outer wall of the fine-tuning rod 303, the fine-tuning block 306 is threadedly connected to the outer wall of one end of the fine-tuning rod 303, the fine-tuning block 306 is slidably embedded in the inner wall slot of the limiting plate 307, the second clamping block 309 is fixedly set at the top of the outer wall of the fine-tuning block 306, the first clamping block 308 is fixedly set at the top of the outer wall of the limiting plate 307, the fine-tuning button 304 is fixedly set at the outer wall of one end of the fine-tuning rod 303, the spring sleeve 305 is embedded in the inner wall of the limiting plate 307, the clamping component of the semi-automatic micro-spot welding machine is precisely designed, and it shows significant advantages in the stable clamping of the welded parts during the welding process, which are specifically described as follows: stable clamping, ensuring welding accuracy, double Clamping design: The clamping assembly double-clamps the weldment through the first clamping block 308 and the second clamping block 309. This design not only improves the stability of the clamping, but also effectively prevents the movement or deformation of the weldment during the welding process, thereby ensuring the accuracy and consistency of the welding. Fine-tuning mechanism: The fine-tuning rod 303, the fine-tuning block 306 and the fine-tuning button 304 together constitute the fine-tuning mechanism. By rotating the fine-tuning button 304, the fine-tuning rod 303 can be driven to rotate, and then the fine-tuning block 306 can be driven to slide on the inner wall groove of the limit plate 307. This fine-tuning mechanism enables the second clamping block 309 to be finely adjusted as needed to adapt to weldments of different sizes and shapes, ensuring the tightness and stability of the clamping, elastic clamping, and protecting the weldment. Buffering effect of spring sleeve 305: Spring sleeve 305 is sleeved on the outer wall of fine-tuning rod 303 and embedded in the inner wall of limit plate 307. During the clamping process, spring sleeve 305 can provide a certain elastic buffer, effectively reducing the impact and damage of clamping force on welded parts, and protecting the surface quality and integrity of welded parts. Adaptive clamping: Due to the elastic effect of spring sleeve 305, the clamping assembly can adaptively adjust the clamping force to adapt to welded parts of different materials and thicknesses. This adaptive clamping capability not only improves the stability of clamping, but also effectively avoids deformation or damage of welded parts caused by excessive clamping force during welding. It is simple to operate, improves work efficiency, and is easy to adjust: the design of fine-tuning button 304 makes the adjustment process simple and quick.The operator only needs to gently rotate the fine-tuning knob 304 to achieve fine adjustments in the clamping force. This design not only improves the convenience of operation, but also effectively shortens the preparation time for clamping and welding, thereby improving work efficiency.
