[0062] The following specific embodiments are exemplary and non-limiting, and are intended to provide a basic understanding of the present application, and are not intended to identify the key or decisive elements of the present application or to limit the scope of protection. As long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way.

[0063] When a component is considered to be “provided on” another component, it can be directly provided on the other component or there may be a component in between. When a component is considered to be “connected to” another component, it can be directly connected to the other component or there may be a component in between.

[0064] It can be understood that the term "perpendicular" is used to describe an ideal state between two components. In actual production or use, there may be a state that is approximately perpendicular or equal to each other between the two components. For example, in combination with numerical descriptions, perpendicularity can refer to the angle between two straight lines being between 90°±10°, perpendicularity can also refer to the dihedral angle between two planes being between 90°±10°, and perpendicularity can also refer to the angle between a straight line and a plane being between 90°±10°. The two components described as "perpendicular" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic perspective, a component can be considered a "straight line" or a "plane" if the overall extension direction is a straight line or a plane.

[0065] Unless otherwise defined, when the term "plurality" is used to describe the number of components, it specifically means that the components are two or more.

The feeding mechanism is connected to the fixed plate, and is partially arranged at the opening. A plurality of workpieces are stacked in the feeding mechanism, and the feeding mechanism is used to lift the workpiece so that the workpiece located at the top abuts against the side of the material strip away from the holding mechanism. The welding mechanism is used to weld the workpiece and the material strip through the through hole.

[0109] See also Figure 2In some embodiments, the welding device 100 includes a detection member 80, which is disposed between the welding mechanism 50 and the feeding mechanism 20, and is used to detect whether the workpiece 200 and the material strip 300 welded by the welding mechanism 50 meet the requirements. Optionally, the detection member 80 includes a CCD camera.

[0110] In some embodiments, the welding device 100 includes a warning module (not shown), which is electrically connected to the detection component 80. When the detection component 80 detects that the welding does not meet the requirements, a reminder is issued to facilitate the machine operator to identify the workpiece 200 and the material strip 300 with poor welding.

[0111] When the above-mentioned welding device 100 is in use, first, the feeding mechanism 20 pulls the material strip 300 to move a predetermined distance, so that the material strip 300 of the unwelded workpiece 200 moves to the position of the second fixed plate 12, and then the pressing driving member 34 drives the pressing plate 31 to move, so that the positioning pin 36 is set in the hole 612 and the positioning hole 310, and the material strip 300 is pressed against the second fixed plate 12, and then the driving member 431 is pushed to drive the push rod 432 to move, so that the push rod 432 lifts the workpiece 200 located at the top, so that the workpiece 200 is close to the material strip 300, and the welding head 51 welds the workpiece 200 and the material strip 300 through the through hole 30a. After welding is completed, the feeding mechanism 20 pulls the material strip 300, so that the material strip welded with the workpiece 200 passes through the detection member 80 in turn, and the detection member 80 detects whether there is a cold weld, and this cycle is carried out to realize automatic welding.

[0112] In the present application, the feeding mechanism 20 pulls the material belt 300 to move a predetermined distance, the holding mechanism 30 holds the material belt 300 on the fixed plate 10, the feeding mechanism 40 lifts the workpiece 200 so that the workpiece 200 abuts against the material belt 300, and the welding mechanism 50 welds the workpiece 200 and the material belt 300, thereby realizing automated feeding, positioning and welding, improving welding efficiency and yield, and thereby improving production efficiency.
