Moving contact supply device of motor starting protector moving contact welding machine

Abstract

The invention discloses a moving contact supply device of a motor starting protector moving contact welding machine. The motor starting protector moving contact welding machine comprises a workbench,a moving contact welding die bearing mechanism arranged on the workbench and a welding bearing die arranged at the top of the moving contact welding die bearing mechanism. The moving contact supply device comprises a moving contact conveying mechanism, a moving contact ferry mechanism and a moving contact pushing mechanism, and the moving contact conveying mechanism is arranged on the workbench and further located at the position corresponding to the left side of the moving contact welding die bearing mechanism. The moving contact ferry mechanism is arranged on the workbench and further located at the position corresponding to the position between the moving contact conveying mechanism and the moving contact welding die bearing mechanism, and the moving contact pushing mechanism is arranged on the workbench corresponding to the position on the front side of the moving contact conveying mechanism and further matched with the moving contact ferry mechanism. And the moving contact pushingmechanism pushes the moving contact which is output by the moving contact conveying mechanism and received by the moving contact ferry mechanism to the welding bearing die. The operation intensity isrelieved; the labor is saved; and smooth proceeding of subsequent stations is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automatic welding machinery for electrical components, and in particular relates to a moving contact supply device of a moving contact welding machine for a motor starter protector. Background technique [0002] The motor start protector mentioned above is the motor start protector of the refrigeration compressor. The motor start protector of the refrigeration compressor is also called the overload protector of the single-phase AC motor of the refrigeration compressor. Protection, its structure can be seen in a large number of published Chinese patent documents, such as CN2218263Y (self-protection refrigeration compressor thermal protector), CN2287339Y (refrigeration compressor motor protector), CN1207743C (thermal protector), CN2341305Y (current Temperature composite motor protector) and CN100356652C (overload protector for single-phase AC motor), etc. Through the reading of not limited to the aforement...

Problems solved by technology

[0003] In the prior art, workers usually manually weld the aforementioned movable contact to the movable contact spring, that is, the movable contact is welded to the movable contact spring. This operation method has been used for a long time and has been called " However, objectively there are the following technical problems: First, because the moving contact spring piece is relatively small, and because the moving contact is as small as a microbead, the positioning and corresponding difficulty in the welding process is relatively large , the difficulty of welding is also relatively large, so that the welding work intensity of the welders is high and the spirit is always in a state of high tension; The general shortage of resources today makes it very difficult for manufacturers; thirdly, recruiting a large number of welding workers will not only cause a waste of valuable labor resources, but also not conducive to saving the manpower of the product, that is, the labor cost. Finally, the cost is passed on to the protector product. As a result, the protector products are not cheap; Fourth, because the quality of manual welding is related to the experience, responsibility, psychological factors, emotional factors, etc. of the workers to a certain extent, it is impossible to make the welding quality meet the relatively uniform standard requirements, even welding The probability of failure will be relatively high

However, due to the small size of the movable contact, if there is no specific movable contact supply mechanism to deliver it to the welding station (the position corresponding to the welding position on the movable contact spring leaf), it will cause the complete set of motor starter protector Moving Contact Welding Machine Difficult or Impossible to Operate

For this technical problem, the applicant has done a literature search, but in the Chinese and foreign patents and non-patent literature disclosed so far, there is no enlightenment that helps to solve the aforementioned technical problem. Beneficial exploration, the technical solutions to be introduced below are generated under this background
