Description

Automatic welding device for static contact of starting protector of motor of refrigeration compressor

Technical Field

The invention belongs to the technical field of automatic welding devices of electrical components, and particularly relates to an automatic welding device for a stationary contact of a motor starting protector of a refrigeration compressor.

Background

The above mentioned motor start protector for the refrigeration compressor is a single-phase ac motor overload protector for the refrigeration compressor, which provides effective protection for the over-temperature and overload of the single-phase ac motor, and its structure can be found in a large number of published chinese patent documents, such as CN2218263Y (self-protection thermal protector for the refrigeration compressor), CN2287339Y (protector for the refrigeration compressor motor), CN1207743C (thermal protector), CN2341305Y (protector for the current and temperature composite motor), and CN100356652C (overload protector for the single-phase ac motor), etc. It is known from a reading of the patent literature, not limited to the above, in particular from a reading of CN100356652C, combined with the common general knowledge: when a movable contact on a movable contact spring leaf (also called a movable contact spring leaf, the same below) is in contact with a static contact on a static contact spring leaf (also called a static contact spring leaf or a static pin spring leaf, the same below), namely when the movable contact and the static contact are closed, an electric circuit is connected, otherwise, the same example is adopted, so that the function of protecting a compressor motor, namely the function of protecting a single-phase alternating current motor is achieved, and in this regard, the figure 3 of the specification attached drawing of CN104734570A (a non-power-consumption energy-saving single-phase alternating current motor starting protector) can be also referred.

The prior art usually welds the static contact and the static contact spring piece by a worker in a manual mode, namely welds the static contact to the static contact spring piece, and the operation mode has been used for a long time and is self-proved to be 'slow work fine work', but the following technical problems are objectively existed: firstly, because the static contact spring leaf is relatively narrow, and because the static contact is small and the beads are small, the positioning and corresponding difficulty in the welding process is relatively high, and the welding difficulty is also high, so that the welding operation intensity of a welding worker is high, and the spirit is always in a highly tense state; secondly, because the manual welding efficiency is low, the manual welding can only be satisfied by greatly increasing the number of post workers, so that manufacturers are really very difficult at present when the labor resources are generally in shortage; thirdly, the recruitment of a large number of welding workers not only causes precious labor resource waste, but also is not beneficial to saving the labor of the product, namely the labor cost, and finally the cost is transferred to the protector product, so that the protector product is lost and is low in price; fourthly, the quality of manual welding is related to experience, responsibility, psychological factors, emotional factors and the like of workers to a certain extent, so that the welding quality can not meet relatively uniform standard requirements, and even the probability of unqualified welding is relatively high. It goes without saying that the problems not limited to the above mentioned ones can be readily solved if welding machines are used which are structurally sound, easy to operate and have good automation efficiency and guarantee the quality of the weld. However, in both the previously published foreign and non-patent documents, no teaching of automated welding machines is known which would help to remedy the above-mentioned technical problems, for which the applicant has made a permanent and useful search, against which the solution to be described below was made.
