[0004] However, this automatic welding machine has the following defects when used specifically:

[0005] 1. When welding metal plates into a circle, the existing automatic welding machine can only weld one metal plate at a time, and after each welding is completed, the welded metal product needs to be disassembled and the next set of metal plates to be welded needs to be installed, resulting in low overall efficiency of the welding operation. At the same time, the welded metal product is prone to fatigue fracture of the weld during the disassembly process, resulting in cracks at the welded points, and the quality of the welded metal product is low;

[0006] 2. When welding metal plates, existing automatic welding machines need to clamp and fix the metal plates to be welded to ensure the stability of the metal plates during welding, and to prevent the welding seams from shifting due to vibration during welding. However, when clamping and fixing the metal plates, the parts being welded to the metal plates are prone to shielding and blocking the welding points, affecting the continuous welding operation.

[0048] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0049] 1. In a fully automatic welding machine, when the welded metal product is driven to move in a circular motion, the welded metal product is removed from the bottom of the welding gun, and another metal sheet to be welded is moved to the bottom of the welding gun, the force of the rotation of the intermediate gear can synchronously drive the cooling fan blades to rotate, and automatically cool the welded metal product to ensure that when the welded metal product is disassembled, the welding points will not crack due to failure to cool in time, thereby ensuring the strength and quality of the metal product after welding. At the same time, the cooling fan blades that drive the metal product for cooling and positioning are driven by two speed gears, one large and one small. The large gear drives the small gear to rotate, which ensures that the cooling fan blades can rotate 360 ​​degrees multiple times, thereby improving the cooling and shaping effect of the metal product (after welding) at the bottom of the cooling fan blades;

[0050] 2. In the fully automatic welding machine, when the metal sheet is welded, the rotating clamping arm can clamp the metal sheet set inside it to ensure that the metal sheet will not shake or shift when welding, and the welding operation of the metal sheet will not cause the problem of wrong welding. At the same time, the clamping arm that clamps the metal sheet can simultaneously drive the metal sheet to bend, ensuring that the edge parts of the metal sheet (welding points) can be close to each other, and the entire welding operation can be completed by direct welding in the subsequent welding. And during the actual welding, the extension arm set on the top of the welding point can be rotated to make way for the welding point, so that the welding can be completed at one time, ensuring the quality of the metal product after the welding is completed;

[0051] 3. In the fully automatic welding machine, when welding the clamped metal sheets, the welding gun can be lifted and lowered in the vertical direction and telescopically moved in the horizontal direction, so as to facilitate the welding gun to approach the welding point of the metal sheet and realize the automated welding operation (direct welding) and automated metal sheet welding operation. At the same time, when the welded and cooled metal products are disassembled to install another set of metal sheets to be welded, the time of disassembling and installing the metal sheets and products can be synchronized with the welding operation of the metal sheets, so as to maximize the efficiency of the welding process of the metal sheets;

[0052] 4. In the fully automatic welding machine, when welding metal sheets (direct welding), the welding gun can be driven to rotate by the deflection motor driving the gear to rotate, and the direction of the laser beam emitted by the welding gun can be adjusted to expand the welding length when welding metal sheets to meet the welding operation of metal sheets of different sizes and specifications. At the same time, when the welding gun rotates, the lifting and moving operation of the welding gun can be carried out synchronously, so that the welding gun is always close to the welding point of the metal sheet, ensuring the effect of welding the metal sheet.
