Full-automatic multi-station welding system

Abstract

The invention discloses a full-automatic multi-station welding system which mainly comprises a rotary table and driving device, contact bridge storage and feeding devices, contactor feeding and conveying devices, welding machine heads and a discharge component, wherein the rotary table and driving device is internally and externally divided in the shape of a ring in the such way of equal and concentric eight parts and four stations, and the positions are set to be an even number according to the welding positions of welded pieces; eight mechanical arm assemblies are uniformly distributed in the circumferential direction on the upper surface of an outer rotary table; two contact bridge storage and feeding devices, two contactor feeding and conveying devices, two welding machine heads and two discharge devices are correspondingly arranged in sequence on the outer side of eight positions; each contact bridge storage and feeding device is engaged with a lower mechanical arm in the present position; each contactor feeding and conveying device comprises a device for identifying front/back faces and sorting during contactor feeding, a solder dropping device and a contactor cross-pushing device. The full-automatic multi-position welding system achieves synchronization of fully automatically welding, assembling and forming multiple sets of equipment in multiple positions at the same time.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and relates to a fully automatic multi-station welding system. Background technique [0002] Most of the welding of existing high and low voltage contacts and conductive parts adopts non-automatic welding systems of various power types such as carbon rod machines, high frequency machines, sub high frequency machines, intermediate frequency machines, and power frequency machines for single-machine manual or single-machine semi-automatic welding . The existing single-station manual welding system welds products with poor consistency, and it is difficult to guarantee key welding dimensions, resulting in large fluctuations in welding quality and low efficiency; the silver point or contact positioning of the semi-automatic welding system is poor, and there are edge warping, contact Quality problems such as offset, contact overlap, solder collapse, rough surface, poor fusion, discoloration, ...

AI Technical Summary

Problems solved by technology

Also there is no successful automatic multi-station welding system so far, and the existing equipment mainly has the following defects:

The existing technologies all use visual inspection and manual sorting of the front and back surfaces, which is inefficient. Simply using infrared detection to identify contacts and welding surfaces of contacts in the high and low voltage industry, the recognition accuracy can only reach 75%-85% , especially for contacts with carbon content and double gold pieces, it is impossible to identify. In view of the above reasons, automatic identification and automatic sorting cannot be realized

Another requirement of the welding surface is that when brazing, the cladding layer is soaked in the flux first to remove oxides and foreign matter in the soldering layer; at present, the flux solder of the contact or the contact is manually coated and soaked in the trough Manual feeding, no automatic coating and feeding mechanism

[0007] 4) The existing vibration plate runs continuously, vibrates and rotates continuously, the guide rail wears quickly, has many faults, and has a short service life

[0008] The existing single-station manual operation or semi-automatic operation of the assembly of two weldments, when encountering multiple objects to be welded, there is currently no automatic resistance welding system; especially in the case of high and low voltage contact bridge (double gold) welding There are multiple pieces, and when each piece is required to be welded with solder, it is difficult to realize the idea of ​​automatic welding because there are too many pieces to be welded.
