Description

Full-automatic detection machine for elasticity of movable contact spring piece of motor protector

Technical Field

The utility model belongs to the technical field of electric parts automatic testing arrangement, concretely relates to full automated inspection machine of motor protector movable contact spring leaf elasticity.

Background

The above-mentioned motor protector is a refrigeration compressor motor protector, and the refrigeration compressor motor protector is also called a refrigeration compressor single-phase alternating current motor overload protector, and provides effective protection for temperature over-temperature and 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 of a 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 of the base part of the pin, namely when the movable contact is closed with the fixed contact, the electric circuit is communicated, otherwise, the same example is adopted, so that the function of protecting the compressor motor, namely the function of protecting the single-phase alternating current motor is realized. Specifically, when the radiation of the electric heating wire or the aluminum cover or the external environment is lower than the sensing temperature at which the bimetallic strip can deform, the bimetallic strip resets, the ejector rod does not generate acting force on the free end of the spring strip (the movable contact is positioned at the free end of the spring strip), namely does not push the spring strip, and the movable contact upwards returns under the action of the elastic restoring force of the spring strip to be closed with the static contact, so that the motor circuit is connected. See CN100356652C, page 6 of the specification.

As can be seen from the above description, the elasticity of the movable contact spring leaf as a structural system of the motor protector of the refrigeration compressor must meet the process requirements, which are: when the push rod pushes the free end, the elastic deformation of the push rod must ensure that the movable contact on the push rod is separated from the static contact on the pin of the protector, and when the push rod does not push the free end, the push rod must be timely restored to make the movable contact and the static contact.

The prior art is lack of reasonable technical measures, and the detection of whether the elastic deformation of the movable contact spring piece meets the requirements is mainly carried out in the following three modes: firstly, acting or relieving action on the ejector rod through artificial preset force, and simultaneously observing whether a movable contact on the spring piece is in contact with or separated from a static contact by an online operator; secondly, the elasticity of the spring piece is judged by the hand feeling of workers; and thirdly, connecting the assembled motor starting protectors of the refrigeration compressors of the same batch in a circuit simulating actual use in a human spot check mode, so as to verify the elasticity of the movable contact spring piece. The first of the three aforementioned modes is deficient in that: the method has great blindness and subjectivity, because the judgment is difficult or even impossible to scientifically judge according to relatively uniform judgment standards, and the detection efficiency is low, especially the detection result is different due to the difference of responsibility, experience, emotion, working attitude and the like of a detector; the second of the three aforementioned modes also exists that the first mode described above differs from person to person and even the same person does not draw substantially the same result as to the elasticity of the same batch of movable contact spring pieces, even does not exclude the conclusion of the contrary, and moreover the detection efficiency is very low; the third of the above three methods, although it can draw a relatively scientific and reasonable conclusion, cannot represent all the methods individually by spot inspection, i.e. there is a defect of dot coverage, so that the limitations are relatively large and the detection cost is high.

In view of the above-mentioned prior art, the above technical problems can be solved if a mechanical energy is relatively efficient and can fully automatically perform a non-sparse and non-leaking same-standard detection on each movable contact spring piece, but no reference is seen in the published Chinese and foreign patent documents to date to help solve the above technical problems. The applicant has made a painstaking and useful iterative design for this purpose, which ultimately results in the solution described below.

Therefore, the ascending and descending strokes of the loading nozzle longitudinal displacement acting cylinder slider 321 are defined between the top and bottom first position signal collector seats i 322, i.e., between the top and bottom first position signal collectors i 3221.

In fig. 2, a second position signal collector seat ii 342 is shown, which is provided at each of the left and right ends of the feeding nozzle lateral displacement acting cylinder 34, and a second position signal collector ii 3421 is provided on the second position signal collector seat ii 342, and when the feeding nozzle lateral displacement acting cylinder block 341 is displaced leftward to such an extent that the second block ram ii 3411 is in contact with the second position signal collector ii 3421 on the left one of the second position signal collector seats ii 342, it indicates that the feeding nozzle lateral displacement acting cylinder block 341 is displaced leftward to the limit, and when the feeding nozzle lateral displacement acting cylinder block 341 is displaced rightward to such an extent that its second block ram ii 3411 is in contact with the second position signal collector ii 3421 on the right one of the second position signal collector seats 342 ii, it indicates that the feeding nozzle lateral displacement acting cylinder block 341 is displaced rightward to the limit.

When feeding is required, namely when feeding is required to be carried out to the receiving mechanism 4 by the feeding mechanism 3 (the material is the 'movable contact spring piece 10' to be detected), firstly, the feeding suction nozzle longitudinal displacement acting cylinder slider 321 is upwards lifted by the feeding suction nozzle longitudinal displacement acting cylinder 32, then the feeding suction nozzle transverse displacement acting cylinder slider 341 is rightwards displaced by the operation of the feeding suction nozzle transverse displacement acting cylinder 34, so that the feeding suction nozzle 35 corresponds to the upper part of the left end of the movable contact spring piece guide groove 241 of the spring piece guide rail 24, then, according to the reverse process, the feeding suction nozzle longitudinal displacement acting cylinder 32 firstly enables the feeding suction nozzle longitudinal displacement acting cylinder slider 321 to downwards displace, so that the feeding suction nozzle 35 descends, the feeding suction nozzle head 351 of the feeding suction nozzle 35 sucks the movable contact spring pieces 10 to be detected in the movable contact spring piece guide groove 241 under the negative pressure (one piece at a time), next, the loading nozzle longitudinal displacement acting cylinder 32 makes the loading nozzle longitudinal displacement acting cylinder slider 321 move upwards, then the loading nozzle transverse displacement acting cylinder 34 works reversely to make the loading nozzle transverse displacement acting cylinder slider 341 move leftwards, the loading nozzle 35 correspondingly moves leftwards to the upper side of the station corresponding to the material receiving mechanism 4 in the state that the loading nozzle head 351 sucks the movable contact spring piece 10, then the loading nozzle longitudinal displacement acting cylinder 32 makes the loading nozzle longitudinal displacement acting cylinder slider 321 move downwards to make the loading nozzle 35 also move downwards, and the loading nozzle 35 at this time changes from negative pressure to positive pressure to make the previously sucked material, i.e. the movable contact spring piece 10, release to the material receiving mechanism 4. The foregoing process is repeated.

In the present embodiment, the loading nozzle longitudinal displacement cylinder 32 and the loading nozzle lateral displacement cylinder 34 are both air cylinders, and the cylinders referred to in the following are also both air cylinders. In this embodiment, the movement of the loading nozzle longitudinal and lateral displacement acting cylinder sliding blocks 321 and 341 is respectively operated by the acting cylinder columns of the loading nozzle longitudinal and lateral displacement acting cylinders 32 and 34, and the following acting cylinder sliding blocks are the same as the mentioned ones.

Since the structural form and the action mechanism of the front and rear detection thimble lifting/lowering action cylinders 612 and 622 are similar to those of the feeding nozzle longitudinal displacement action cylinder 32, the applicant does not describe the above. Taking the front detection table thimble lifting device 61 of the movable contact spring piece as an example, under the operation of the front detection table thimble lifting cylinder 612, the front detection table thimble lifting cylinder slider 6121 is displaced upward to drive the front detection table fixing base 613, the front detection table 614 and the front detection table thimble 615 to correspondingly displace upward, so that the movable contact spring piece head 101 of the movable contact spring piece 10 on the front movable contact spring piece detection bearing base 44 is pushed upward by the front detection table thimble 615, because the movable contact spring piece 10 is usually made of a metal sheet with good elasticity and is conductive, such as a copper sheet, the movable contact spring piece head 101 is lifted upward when the movable contact spring piece head 101 is pushed upward by the front detection table thimble 615, and the pushing force is revealed by the front detection table 614 and can be fed back to the electric controller 15, and at the same time, the degree of upward pushing (lifting) of the movable contact spring piece head 101 can be raised (lifted) by the movable contact spring piece as will be described in detail below The front detector 92 of the structural system of the reed head position change distance detection mechanism 9 detects and feeds back to the electric controller 15. In the foregoing process, under the same pushing force, the movable contact spring pieces 10 of the same specification and batch, that is, the same batch of starters are under the same specification, and if the elasticity of the movable contact spring piece head 101 is insufficient, that is, the movable contact spring piece does not reach the set value range or exceeds the set value range, the movable contact spring piece 10 is an unqualified movable contact spring piece 10, otherwise, the movable contact spring piece 10 is a qualified movable contact spring piece. Since the working process of the rear detection gauge thimble lifting device 62 of the movable contact spring piece is the same as that of the front detection gauge thimble lifting device 61 of the movable contact spring piece, the applicant does not give further details.

Continuing with fig. 1, the preferred, but not absolutely limited, construction of the front take off mechanism 7 described above is as follows: the horizontal displacement action cylinder fixing frame 71 is fixed with the upper rear side of the front suction nozzle horizontal displacement action cylinder fixing frame 71 in a horizontal state, the front suction nozzle lifting action cylinder 73 is fixed with the rear side of the front suction nozzle lifting action cylinder base 731 in a longitudinal state, the front material taking suction nozzle lifting cylinder base 731 is fixed to the rear side of the front material taking suction nozzle horizontal displacement cylinder slider 721 of the front material taking suction nozzle horizontal displacement cylinder 72, the front material taking suction nozzle translation cylinder fixing platform 74 is fixed to the upper portion of the front material taking suction nozzle lifting cylinder slider 732 of the front material taking suction nozzle lifting cylinder 73, the front material taking suction nozzle translation cylinder 75 is fixed to the upward side of the front material taking suction nozzle translation cylinder fixing platform 74 in a horizontal state, the front material taking suction nozzle fixing base 76 is fixed to the end of the front material taking suction nozzle translation cylinder slider 751 of the front material taking suction nozzle translation cylinder 75 facing the material receiving mechanism 4, and the rear end of the front material taking suction nozzle fixing seat 76 is extended out of the end surface of the front material taking suction nozzle translation acting cylinder slide block 751 facing to one end of the material receiving mechanism 4, and the front material taking suction nozzle 77 is fixed at the rear end of the front material taking suction nozzle fixing seat 76 and is corresponding to the upper part of the front movable contact spring piece detection bearing seat 44. In fact, the front pickup nozzle 77 and the front pickup nozzle holder 76 are integrally formed with each other and substantially identical to the structure of the loading nozzle 35, and thus, a detailed description thereof will not be provided.

Since the actual structure and mechanism of the aforementioned front pickup nozzle horizontal displacement action cylinder 72 and the front pickup nozzle translation action cylinder 75 are substantially the same as those of the aforementioned loading nozzle lateral displacement action cylinder 34 and will not be confused by those skilled in the art, the applicant is not presented with the same explanation as that of the above-mentioned loading nozzle lateral displacement action cylinder 34.

When the detected movable contact spring piece 10 is to be removed from the front movable contact spring piece detecting bearing seat 44, the front material taking suction nozzle lifting acting cylinder 73 is firstly operated to make the front material taking suction nozzle lifting acting cylinder slider 732 lift the front material taking suction nozzle lifting acting cylinder seat 731 and the front material taking suction nozzle translation acting cylinder 75 upwards, then the front material taking suction nozzle horizontal displacement acting cylinder 72 is operated to make the front material taking suction nozzle horizontal displacement acting cylinder slider 721 displace leftwards, the front material taking suction nozzle lifting acting cylinder 73 and the front material taking suction nozzle translation acting cylinder 75 correspondingly displace leftwards until the front material taking suction nozzle translation acting cylinder 75 corresponds to the position of the front movable contact spring piece detecting bearing seat 44 and the front suction nozzle 77 corresponds to the upper part of the front movable contact spring piece detecting bearing seat 44, because the detected movable contact spring piece 10 is already on the front movable contact spring piece detecting bearing seat 44, so that the front pickup nozzle 77 actually corresponds to the upper side of the movable contact spring piece 10. At this time, the front material taking nozzle lifting cylinder 73 works reversely, the front material taking nozzle translation cylinder fixing platform 74, the front material taking nozzle translation cylinder 75 and the front material taking nozzle 77 move downwards due to the downward movement of the front material taking nozzle lifting cylinder slider 732, and the front material taking nozzle 77 sucks the movable contact spring piece 10 under the negative pressure action (the principle is completely the same as that of the feeding nozzle 35). Then, the front pickup nozzle elevating cylinder 73 operates in the reverse direction to displace the front pickup nozzle 77 upward in a state of sucking the movable contact spring piece 10, and then, the front pickup nozzle translation cylinder 75 displaces forward in the direction opposite to the previous direction to drive the front pickup nozzle 77 sucking the movable contact spring piece 10 to displace forward accordingly. Then, the action cylinder 72 is horizontally displaced by the front material-taking suction nozzle to move in the direction opposite to the above direction, so that the front material-taking suction nozzle 77 corresponds to the material inlet 121 of the leading-out groove, and at the same time, the front material-taking suction nozzle 77 becomes positive pressure to release the qualified moving contact spring piece 10 to the qualified moving contact spring piece leading-out groove 12 and lead the qualified moving contact spring piece into the above-mentioned material-containing box 1421. If the test result is unqualified, the front material taking suction nozzle translation action cylinder 75 continues to act, the front material taking suction nozzle translation action cylinder slide block 751 continues to displace forwards, so that the position of the previous front material taking suction nozzle 77 corresponding to the material inlet 121 of the leading-out groove is changed to be corresponding to the upper part of the unqualified movable contact spring piece first material receiving box I13 a, and the unqualified movable contact spring piece 10 is released into the unqualified movable contact spring piece first material receiving box I13 a. This is repeated.

In fact, the rear pickup nozzle 87 and the rear pickup nozzle holder 86 are integrally formed with each other and substantially identical to the structure of the loading nozzle 35, and thus, a detailed description thereof will be omitted.

Since the working process of the rear material taking mechanism 8 is substantially the same as that of the front material taking mechanism 7, and the working process of the rear material taking mechanism 8 is not confused as long as the working process of the front material taking mechanism 7 is read in detail, the applicant does not repeat the description of the working process of the rear material taking mechanism 8.
