[0013] The present invention provides a notebook stand welding system with a positioning structure, which has the following beneficial effects: 1. The laptop stand welding system with a positioning structure, when in use, sends the fixture containing the workpiece to the bottom of the workbench through the external feeding mechanism, and then drives the motor to drive the positioning device to rotate. When the positioning device rotates to a position facing the workpiece, the arc-shaped telescopic rod is extended to drive the positioning bracket to rotate around the rotating seat, and the positioning bracket drives the shovel head to rotate, and the fixture containing the workpiece is clamped by the shovel head. Since the positioning device is set as an annular structure, and multiple groups of clamping structures are set on the annular structure, the rotation of the positioning device can drive the multiple groups of clamping structures to rotate to realize circulation, so that the device can rotate continuously and occupy less space, which is convenient for achieving higher processing efficiency in a smaller space.

[0014] 2. The laptop stand welding system with a positioning structure has a flat shovel and an extrusion head inside the shovel head. The workpiece can be scooped up by the flat shovel, and then squeezed and fixed by the extrusion head. The flat shovel can be suitable for different feeding structures.

[0015] 3. The laptop stand welding system with a positioning structure, when the shovel head scoops up the jig, the extrusion push rod extends to drive the extrusion bar to move toward the jig, and the extrusion bar drives the electric heating plate and the extrusion spring piece to move toward the jig. When it moves to a certain position, the extrusion spring piece is first squeezed onto the surface of the jig, and the extrusion spring piece is bent by the reaction force of the jig. When the extrusion continues, the electric heating plate is then squeezed onto the jig. The jig can be stably fixed on the shovel head by extrusion, so that the jig can remain stable during the operation of the device, avoiding the position of the jig affecting subsequent processing. At the same time, an electric heating plate is also provided to heat the jig, and the heat of the electric heating plate is transferred to the workpiece inside the jig through the jig, so that the workpiece can be preheated, avoiding the situation where the temperature difference of the workpiece during welding affects the welding quality.

[0016] 4. The laptop stand welding system with a positioning structure, when the welding of the workpiece in the jig is completed, the driving motor drives the positioning device to rotate, and the positioning device drives the jig and the workpiece inside it to rotate. At this time, cold air can be sent into the arc-shaped air duct through the fan, and the cold air enters the air outlet through the arc-shaped air duct. After being heated by the electric heating wire inside the air outlet, the cold air is discharged from the air outlet to the jig inside the positioning device, thereby cooling the jig and the workpiece inside the jig. Since the electric heating wire is provided and the power of the electric heating wire decreases successively, the temperature of the wind blowing to the jig will gradually decrease during the rotation of the jig with the positioning device, so that the temperature of the jig and the workpiece will slowly decrease during the cooling process, thereby avoiding a large temperature difference after welding, which may cause cracks in the weld or affect the welding quality.
