Full-automatic spot welding machine

Abstract

The invention relates to the technical field of spot welding machine, in particular to a full automatic spot welding machine. The spot welding machine is provided with an upper electrode, a lower electrode, a soldering terminal conveying device, a soldering terminal conveying vibration disk, a workpiece conveying device and a workpiece conveying vibration disk, wherein the soldering terminal is conveyed in a welding terminal conveying groove of the welding terminal conveying device through the welding terminal conveying vibration disk; and the soldering terminal is pushed in a fixing hole of the lower electrode by a pushing cutter of the welding terminal conveying device, thereby completing the automatic conveying and positioning of the soldering terminal; besides, the workpiece conveying vibration disk conveys the workpiece in a work piece conveying groove of the workpiece conveying device, the workpiece conveying device clips the workpiece through a clipping cylinder, a rotary cylinder drives the clipping cylinder to rotate, and the workpiece is positioned on the upper part of the lower electrode, thereby completing the full automatic conveying and positioning of the workpiece; and at last, a working cylinder drives the upper electrode to descend to complete the automatic spot welding. The full automatic spot welding machine has the advantages of realizing the full automatic spot welding processing, improving the working efficiency, improving the spot welding quality and lowering the production cost.

Description

Technical field: [0001] The invention relates to the technical field of spot welding machines, in particular to a fully automatic spot welding machine. Background technique: [0002] In order to make electrical connectors and other workpieces have good contact performance with other parts or to make the welding part of the workpiece have better welding performance, usually a solder piece is fixed at a specific position of the workpiece. The current technology is to place the solder piece through spot welding. It is fixed on the workpiece, and the spot welding process of the workpiece is carried out manually by the workers. Since the spot welding is manual operation, the size of the solder joints is different, the spot welding effect is unstable, the quality of spot welding is not guaranteed, and the efficiency of spot welding work Low, high labor costs, in addition, the solder contains a large amount of harmful substances such as lead Pb, cadmium Cd, mercury Hg, which does n...

[0002] In order to make electrical connectors and other workpieces have good contact performance with other parts or to make the welding part of the workpiece have better welding performance, usually a solder piece is fixed at a specific position of the workpiece. The current technology is to place the solder piece through spot welding. It is fixed on the workpiece, and the spot welding process of the workpiece is carried out manually by the workers. Since the spot welding is manual operation, the size of the solder joints is different, the spot welding effect is unstable, the quality of spot welding is not guaranteed, and the efficiency of spot welding work Low, high labor cost, in addition, the solder contains a large amount of harmful substances such as lead Pb, cadmium Cd, mercury Hg, etc., which does not meet environmental protection requirements

At present, there are also a small number of enterprises that have developed semi-automatic spot welding machines, which can realize spot welding through mechanical equipment. However, semi-automatic spot welding machines have complex structures and do not have the functions of automatically sending welding pieces and workpieces. All must be manually sent to the spot welding area of ​​the semi-automatic spot welding machine by the workers for spot welding processing. Although the semi-automatic spot welding machine has solved the problem of automatic spot welding, there are still many problems. For example: first, the workers manually send the welding pieces and There are potential safety hazards in the operation of the workpiece; second, during spot welding, the positioning of the welding sheet and the workpiece is not accurate, and unqualified products are prone to appear, and the quality of spot welding is still not high; third, because the transportation and positioning of the welding sheet and the workpiece are still Operated manually, the work efficiency is still not high
