Description

Welding platform structure of protector stationary contact automatic weld machine
Technical Field
The utility model belongs to the technical field of refrigeration compressor electrical component automatic weld machinery, concretely relates to welding platform structure of protector stationary contact automatic weld machine.
Background
The motor start protector mentioned above is a motor start protector of a refrigeration compressor, which is also commonly referred to as a single-phase ac motor overload protector of the refrigeration compressor, and the motor start protector of the refrigeration compressor has the function of providing effective protection for temperature over-temperature overload of the single-phase ac motor, and the structure thereof can be found 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 of the single-phase ac motor), and so on. 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, if the stationary contact is welded to the stationary contact spring piece, that is, if the stationary contact is welded to the stationary contact spring piece, the stationary contact spring piece needs to be supported by a relatively reasonable supporting platform, otherwise, welding cannot be performed; in addition, the volume of the supporting platform is also effectively controlled, otherwise, the overall volume of the welding machine is increased; moreover, because the volume of the static contact is small and the static contact is micro-bead, if the static contact is welded with the static contact spring piece at the station of the supporting platform, the static contact must be effectively limited or regulated, otherwise the welding position accuracy is influenced due to the floating (namely displacement), and the electric performance is influenced due to the fact that the static contact cannot be fully aligned and contacted with the opposite side surface of the movable contact in the using process. In view of the above technical factors, the applicant has conducted a literature search, but there is no technical teaching in the prior art patent and non-patent documents disclosed so far to solve the above technical problems, and the technical solutions to be described below are made in such a background.
