[0002] Spot welding machines are used for joining metals and are quite common in metal processing. With the advancement of welding technology and the increasing demands for welding, welding equipment has become more and more diversified. Spot welding machines are a type of welding equipment with a long history and still play an important role in industry today.

[0003] During the production of household freezer doors, spot welding machines are required. However, traditional spot welding machines lack side positioning and planar support, requiring one person to hold the door panel in place for spot welding. For lean production, the two-person process involves picking up the door panel, picking up the lining iron, fixing the lining iron, spot welding, fixing the door panel, flipping / moving the door panel, and placing the door panel. This is cumbersome, inefficient, and time-consuming. The manual handling of the workpiece and the foot switch pose safety hazards. To improve the issue of lining iron deviation of 3mm-5mm, the door panel is designed with fixing holes to control the spot welding deviation to below 2mm. The presence of fixing holes in the product components necessitates two-point spot welding to ensure the lining iron is secure, and the defect rate of lining iron spot welding deviation is relatively high. Therefore, we propose a dual-station spot welding machine for freezer lining iron installation. Utility Model Content
