Movable contact spring piece supply device of movable contact welding machine of motor starting protector

Abstract

The invention relates to a movable contact spring piece supply device of a movable contact welding machine of a motor starting protector. The movable contact welding machine of the motor starting protector comprises a workbench, a movable contact welding die bearing mechanism supported on the workbench, a welding bearing die arranged at the top of the movable contact welding die bearing mechanism,a movable contact spring piece welding bearing table displacement mechanism arranged on the workbench and corresponding to the front side of the movable contact welding die bearing mechanism, and a movable contact spring piece welding bearing table arranged on the movable contact spring piece welding bearing table displacement mechanism. The movable contact spring piece supply device comprises amovable contact spring piece conveying mechanism and a movable contact spring piece transferring mechanism, wherein the movable contact spring piece conveying mechanism is arranged on the workbench and corresponding to the front side of the movable contact welding die bearing mechanism, and the movable contact spring piece transferring mechanism is arranged on the workbench and corresponding to the right side of the movable contact spring piece conveying mechanism. The movable contact spring piece supply device has the advantages of reducing the operation intensity, saving the labor force, andensuring the smooth operation of subsequent stations.

Description

Technical field[0001]The invention belongs to the technical field of automatic welding machines for electrical components, and in particular relates to a movable contact spring sheet supply device of a movable contact welding machine for a motor starter protector.Background technique[0002]The motor start protector mentioned above is the refrigeration compressor motor start protector. The refrigeration compressor motor start protector is also called the refrigeration compressor single-phase AC motor overload protector, which is effective for the temperature over-temperature and overload of the single-phase AC motor. Protection, its structure can be seen in a large number of public Chinese patent documents, such as CN2218263Y (self-protected refrigeration compressor thermal protector), CN2287339Y (refrigeration compressor motor protector), CN1207743C (thermal protector), CN2341305Y (current Temperature composite motor protector) and CN100356652C (single-phase AC motor overload protect...

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 relatively uniform (that is, consistent) standards Requirements, even the probability of unqualified welding will be relatively high

However, due to the small size of the movable contact spring piece and its shape is generally T-shaped as shown by CN104734570A (called "movable contact spring piece"), if there is no specific movable contact spring piece supply mechanism to deliver it To the welding station for welding with the moving contact, it will make it difficult or even impossible for the complete set of motor starter protector moving contact welding machine 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
