Description

Welding platform structure of motor starting protector movable contact welding machine

Technical Field

The invention belongs to the technical field of automatic welding machinery of electrical components, and particularly relates to a welding platform structure of a moving contact welding machine of a motor starting protector.

Background

The motor start protector mentioned above is referred to as a refrigeration compressor motor start protector, and the refrigeration compressor motor start protector is also commonly referred to as a refrigeration compressor single-phase alternating current motor overload protector in the industry, and provides effective protection for temperature overtemperature overload of a single-phase alternating current 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 for single-phase alternating current motor), and the like. 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 the movable contact on the movable contact spring sheet is in contact with the fixed contact at the base of the pin, namely when the movable contact is closed with the fixed contact, the electric circuit is connected, and vice versa, the function of protecting the compressor motor, namely the single-phase alternating-current motor is realized, and for this, the detailed description can be seen in fig. 3 of the attached drawing of the specification of CN104734570A (power-consumption-free energy-saving single-phase alternating-current motor starting protector).

Previously, the aforementioned movable contact is welded to the movable contact spring piece, i.e. the movable contact is welded to the movable contact spring piece, usually by a worker in a manual manner, which has been used to date and is known as "slow work and fine work", but the following technical problems have been found objectively: firstly, because the movable contact spring leaf is relatively narrow, and because the movable contact is small as a microbead, 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, when the moving contact is welded and fixed to the moving contact spring piece by using an automatic welding machine, a welding platform (namely a welding supporting platform) is required to guarantee. In particular: the movable contact spring piece provided by the movable contact spring piece supply device and the movable contact provided by the movable contact spring piece supply device need to be supported by the welding platform when welding of the welding head is carried out, otherwise, the welding action cannot be completed. In addition, because the diameter and thickness of the movable contact, namely the volume of the whole movable contact, are small and small like beads, if reasonable control measures are lacked, the movable contact can be displaced or moved in the process of welding the movable contact to the movable contact spring piece by a welding head, so that the welding position of the movable contact on the movable contact spring piece deviates from the position required by the process, and in the using process of a product, the surface of the opposite side of the movable contact and the fixed contact can not be accurately and comprehensively contacted, so that the electrical property effect is influenced, and even the product is scrapped. The method is a beneficial measure for guaranteeing the welding quality by providing a welding bearing die (namely, the movable contact bearing die, the same is used below) for the movable contact, so that the movable contact to be welded is accurately welded to the movable contact spring piece without deviation under the constraint (control) of the welding bearing die. However, the aforementioned weld carrier die also needs to be supported by the weld platform. As can be seen from the foregoing description, the welding platform is an essential device serving as a movable contact welder for a motor start protector, however, no reference technical information is available in the prior art patents and non-patent documents, and the technical solutions to be described below are made in this context.

As can be seen from the schematic of fig. 4, the diameter of the upper part of the welding carrier die 10 is larger than that of the lower part, and the applicant uses the term expanded because the diameter of the movable contact accommodating cavity 1011 is larger than that of the thimble hole 101. When welded, the movable contact 40 shown in fig. 4 is located within the movable contact receiving cavity 1011.

Since there is a possibility that adhesion may occur between the movable contact 40 and the wall of the movable contact accommodating cavity 1011 during welding, especially in order to facilitate driving the movable contact 40 and the movable contact spring 50, which have been welded by the movable contact spring 50, away from the welding carrier 10, the pin driving cylinder 43 (in this embodiment, a cylinder) is operated once after each welding is completed, so that the pin is displaced upward once, the top of the pin 44 shown in fig. 4 is inserted into the pin hole 101, and the pin and the movable contact 40 are pushed, so that the movable contact 40 and the movable contact spring 50, which have been welded, are driven away from the welding carrier 10 and fall into a position corresponding to the discharge groove fixing hole 414 (a pair shown in fig. 4 and in this embodiment) preset on the welding stage holder support 41, fixed in an inclined state to the welding stage holder support 41 and fixed by the welding stage holder support 41 in fig. 1, The chute 60 shown in fig. 2 and 6 is drawn out from the chute 60.

At this time, the movable contact ferry mechanism 6 operates, and according to the above description of the applicant, the movable contact transition groove 631 on the movable contact ferry push plate 63 corresponds to the right end of the movable contact sliding guide rail groove 221, the movable contact 40 enters one movable contact transition groove 631, and the movable contact ferry push plate moving action cylinder 62 of the movable contact ferry mechanism 6 operates in the reverse direction to displace the movable contact ferry push plate 63 in the reverse direction with respect to the displacement direction, so that the movable contact 40 located on the movable contact transition groove 631 corresponds to the movable contact sliding groove 3011 of the movable contact transition guide 301 and the push rod fitting groove 3031 in accordance with the correspondence between the movable contact transition groove 631 and the movable contact sliding groove 3011 and the push rod fitting groove 3031, that is, the movable contact 40 corresponds to the space between the movable contact sliding groove 3011 and the push rod fitting groove 3031. When the movable contact pushing mechanism 7 is operated, the movable contact pushing rod pushes the movable contact 40 into the movable contact accommodating cavity 1011 at the upper part of the bearing die top pin hole 101 of the welding bearing die 10, after the pushing is finished, the movable contact pushing rod drives the acting cylinder 72 to work reversely so as to return the movable contact pushing rod 74 (displace leftwards), and the movable contact ferry push plate moving acting cylinder 62 also works reversely so as to displace the movable contact ferry push plate 63 backwards to make the movable contact transition groove 631 correspond to the movable contact sliding guide rail groove 221 again to receive the movable contact 40.

Then, the movable contact spring piece transfer suction nozzle lateral displacement acting cylinder 82 works to make the movable contact spring piece transfer suction nozzle lateral displacement acting cylinder slider 821 move backward, i.e. towards the movable contact spring piece welding bearing table 20, until the movable contact spring piece transfer suction nozzle 86 sucking the movable contact spring piece 50 is correspondingly above the movable contact spring piece accommodating cavity 201 of the movable contact spring piece welding bearing table 20.

At this time, the welding head vertical displacement driving mechanism 9 works, specifically: the welding head lifting cylinder 92 moves the welding head lifting cylinder 921 downward, the welding head lifting cylinder 921 pushes the welding head fixing base connection slider 93, the welding head fixing base 94 and the welding head 95 downward, the lower end of the welding head 95 is welded in a state of contacting with the welding part of the movable contact spring piece 50 (the welding machine 14 is in a working state), the movable contact 40 and the welding part (downward side) of the movable contact spring piece 50 are consolidated into a whole, and then the welding head 95 is moved upward and returned to a standby state under the reverse operation of the welding head lifting cylinder 92, that is, in a state of preparing for welding the welding part of the movable contact 40 and the movable contact spring piece 50 in the next process.

After the welding is completed, the movable contact spring piece welding plummer displacement mechanism 5 operates, the plummer up-down displacement action cylinder 55 operates to make the plummer up-down displacement action cylinder slide 551 move down to drive the movable contact spring piece welding plummer 20 to move down, then the plummer up-down displacement action cylinder 53 operates to drive the plummer up-down displacement action cylinder 55 and the movable contact spring piece welding plummer 20 to move forward (taking the position state of fig. 1 as an example) by the plummer up-down displacement action cylinder slide 531, and in this state, the movable contact spring piece 50 and the movable contact 40 which have previously completed the welding are in a half-suspended state on the welding plummer 10. At this time, under the operation of the thimble driving action cylinder 43 of the structural system of the movable contact welding mold carrying mechanism 4, the thimble 44 goes upward to push and push the movable contact 40 upward, so that the movable contact spring piece 50 together with the movable contact leaves the welding carrying mold 10 and falls to the discharge chute 60.

Since the above mechanisms are operated in a continuous and repetitive manner, the applicant does not describe the repetitive operation.

In conclusion, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the invention task and truly realizes the technical effects of the applicant in the technical effect column.
