Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a full-automatic wire trimming welding machine. Background Art

[0002] The fully automatic wire cutting and welding machine, also known as the wire welding machine, is an automated processing equipment that cuts and strips wires to a certain size and welds them to electronic components. It is an indispensable equipment for the processing of many electronic components.

[0003] Traditional welding machines use a welding gun to contact the tin bar, which is driven by a mobile device to descend in height and contact the electronic components. The stripped wires are then welded to the electronic components. When the wires at that position are welded to the electronic parts, the welding gun and the tin bar rise and are moved left and right by another mobile device to proceed to the next position.

[0004] In the process of implementing the solution, the inventors found that the following problems existed in the prior art and have not been well solved: due to the long-term contact between the end of the welding gun and the tin bar, a large amount of tin liquid appears at the end of the tin bar due to the long-term contact with the tin bar. When the next welding is performed, the tin liquid will be transferred to the welding point. Since the amount of tin liquid is greater than the required welding amount, the welding point will be too large, resulting in a decrease in aesthetics, obstruction of current flow, increase in thermal stress, and increase in short circuit risk. Therefore, the present application proposes a fully automatic wire cutting welding machine. Utility Model Content

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When the welding of the welding gun and the tin bar at welding point A is finished and the mobile device is used to raise them, the micro motor will drive the turntable to rotate through the shaft, and the turntable will drive the pressure rod to move downward through the connection between the eccentric shaft and the sleeve connecting rod, so that the arc tube above can press the tin bar and perform a slightly bent lowering movement, so that the end of the tin bar close to the welding gun can avoid contact with the welding gun or stay away from the welding gun, avoiding the heat of the welding gun from melting the tin bar in contact, which will lead to welding problems caused by excessive tin liquid at the end of the welding gun.
