Automatic spot welding machine

Abstract

An automatic spot welding machine comprises a rack, an automatic material distributing mechanism, an automatic feeding mechanism, an automatic spot welding mechanism, a support frame, a sensing element, various cylinders and other parts, wherein the automatic material distributing mechanism, the automatic feeding mechanism, the automatic spot welding mechanism, the support frame, the sensing element, various cylinders and the parts are sequentially arranged on the rack. Via the reasonable distribution, the automatic spot welding machine can automatically distribute and feed materials and conduct spot welding on a boneless wiper steel blade, various problems and hidden dangers existing in machining of the boneless wiper steel blade are effectively solved and eliminated, the labor intensity of a worker is greatly reduced, in addition, multiple machines can be operated by one person, so that the machining efficiency is remarkably improved. The automatic spot welding machine is reasonable in cost, high in degree of automation and humanized in operation, a common worker can operate the machine after experiencing simple operation training, great resources are saved for an enterprise, and therefore, the automatic spot welding machine is worthy of popularization in a wide range.

Description

technical field [0001] The invention relates to a spot welding machine, in particular to an automatic spot welding machine for spot welding and fixing boneless wiper steel sheets. Background technique [0002] The boneless wiper is mainly assembled from four accessories including wiper rubber strip, boneless wiper steel sheet, wiper sheath, and plastic parts. Ordinary wipers rely on the skeleton to make the blade and the glass bond together. Due to its structure, it is impossible to make the blade and the glass fit perfectly, which will easily cause problems such as unclean cleaning, easy wear of the blade, and loud noise. Boneless wiper blades use a whole piece of boneless wiper blade steel (force guiding strip) to disperse the pressure, so that the force on each part of the wiper blade is even, which can reduce the generation of water marks and scratches, and achieve better wiping effect. Compared with ordinary wipers, boneless wipers can greatly reduce the vibration and ...

AI Technical Summary

Problems solved by technology

During processing, if the traditional welding method is used to weld and fix the elastic steel sheet, it is easy to weld through, shorten, change the angle, bend and deform the elastic steel sheet, which seriously affects the quality of the wiper. Therefore, the traditional welding method cannot meet the high-quality production of the boneless wiper steel sheet. Require

At present, a small number of manufacturers on the market use spot welding machines to weld boneless wiper steel sheets, but these spot welding machines cannot perform automatic processing. During processing, the workpiece must be manually clamped, and then the connecting parts must be manually placed on the steel sheet Finally, manually control the welding head of the spot welding machine to carry out the spot welding operation. The labor intensity of the whole processing process is very large, and the processing efficiency is low; moreover, the existing spot welding machine mainly adopts the principle of double-sided double-point overcurrent welding. When working, the spot welding machine operates at high voltage. If it is operated by non-professionals, there will be a huge potential safety hazard in power consumption.

[0003] At present, there is no automatic spot welding machine on the market that can automatically divide, feed, and spot weld, and is used for welding and fixing boneless wiper steel sheets.
