Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transformer skeleton pin insertion, and specifically relates to a transformer skeleton pin insertion mechanism. BACKGROUND

[0002] The transformer skeleton, also known as the transformer line frame, is a core insulation and structural support component of the transformer, which is usually made of engineering plastics (such as nylon, PBT, epoxy resin, etc.) with good high-temperature resistance and insulation performance by injection molding. Its main function is to provide a winding carrier for the transformer winding, and through the pre-set line slot, pin slot and other structures, the orderly arrangement of the winding is realized, and the primary and secondary windings are isolated to prevent electrical breakdown and ensure insulation safety. In addition, the skeleton needs to fix the pin and realize the electrical connection between the winding and the external circuit through the pin structure.

[0003] The transformer skeleton pin is a metal conductive connecting piece integrated on the transformer skeleton, which is usually made of copper, brass and other materials with good conductivity. The form is mostly needle-shaped or columnar, which is fixed on the end of the skeleton by injection molding or post-assembly.

[0004] Among them, when assembling the pins of the transformer skeleton, the pin insertion machine is needed to assist in pin insertion. When the pin insertion machine is used for pin insertion and unloading of the transformer skeleton, the transformer skeleton needs to be pushed to the pin insertion position of the feeding frame first, then the pushing frame is raised away from the transformer skeleton, and after the pin insertion is completed, the pushing frame is lowered again, and the pushing control is matched to realize the pin insertion and unloading of the transformer skeleton. Although such cooperation can realize the pin insertion and unloading of the transformer skeleton, in actual use, the above steps need to be completed by multiple cylinders cooperating with each other according to the set steps, and the cooperation of multiple devices will cause waste of resources, and the operator needs to perform a lot of debugging and correction during operation.

[0005] And at present, when the pins of the transformer skeleton are inserted, most of them are directly placed on the feeding position, and then the pins are directly pressed down. Although the transformer skeleton is limited to a certain extent by the sliding rail, deviation between the pins and the reserved holes may still occur. If the feeding step is operated incorrectly or the feeding is insufficient, the pin insertion position is not fed, and the pin insertion operation does not stop, the extended pin will be directly cut off, and the cut pin will basically fall off the device without being limited, which may affect and damage the device.

[0006] And at present, after the insertion of the pin, the transformer skeleton cannot be further and efficiently detected, when the depth of the reserved hole of the transformer skeleton is insufficient or the hole position has a large error with the standard requirement, and the pin depth is set in advance, the pin is easily bent in the pin insertion process, therefore, the unqualified transformer skeleton cannot be timely screened, and the defective products and qualified products are mixed.

[0007] On this basis, the application provides a transformer skeleton pin insertion mechanism to solve the above problems. SUMMARY

[0018] The application has the following technical effects.

[0019] 1. The application adjusts the push rod to work back and forth to pull the front and rear sliding frames, the upper and lower sliding frames and the push frame by a distance, and then pushes the push frame forward by a distance after the pullback is completed. This process drives the push frame to move horizontally first, then moves horizontally and downward along the chute, and then continues to push forward after descending to the appropriate height. The push frame moves from the high position close to the middle position to the direction of the transformer skeleton on the feeding chute, and then moves downward to the left side of the transformer skeleton. After moving to the left side of the transformer skeleton, the transformer skeleton is pushed to the right side, and another push frame at a different position can move along the same trajectory to push the transformer skeleton with pins to the next step. Only one push rod structure is needed to realize the feeding lifting and discharging steps, which reduces the waste of resources caused by the use of a large number of push rods in the traditional structure, and reduces the debugging operation of the equipment. 2. The application drives the main sliding frame and the push plate connected below the main sliding frame to descend through the sliding frame push rod, the push plate first contacts the two pushed frames and pushes them to the two sides at the same time, drives the two extension arms connected with the two pushed frames to rotate towards each other with the positioning shaft center as the center, and makes the two extension arms gradually close to each other. In the closing process, the two positioning blocks first contact the transformer skeleton to be inserted, and the transformer skeleton is positioned and clamped, which reduces the error of pin insertion and the inaccuracy of the position of the transformer skeleton. It greatly reduces the waste of raw materials caused by pin insertion errors, and through the setting of the pressure sensor and the rotary cutting piece, when the material does not reach the pin insertion position in time, the positioning block will not be pressed, and the pressure sensor and the rotary cutting piece will not be triggered, which reduces the influence of the equipment caused by the cutting of the pin falling into the equipment due to operation errors. 3. The application can solve the problem of the pin needle being pressed and bent due to the fixed insertion depth when the reserved hole depth of the transformer skeleton is insufficient or the hole position has a large error with the standard requirement, and the detection can assist in screening out unqualified transformer skeletons.

[0043] Working principle: S1, first, according to the diameter of the pin and the required error range, the pull block 53 drives the top plate 54 to ascend, so that the top plate 54 is separated from the upper surface of the detection frame 15, then the detector 55 is pushed to adjust the distance between the two detection rods 58, after the distance between the two detection rods 58 is adjusted, the pull block 53 is released, the limiting spring 57 drives the detection sliding block 56 and the top plate 54 to descend by the elastic force of itself, the top plate 54, the detector 55 and the detection rod 58 are limited and fixed by the anti-skid groove and the anti-skid block, after the distance of the detection rod 58 is adjusted, the descending process of the sliding frame push rod 9 can be adjusted according to the pin depth; S2, after adjusting the detection rod 58 and the sliding frame push rod 9, the vibration feeder 3 can be controlled to work, and the transformer skeleton is conveyed to the feeding chute 4. During the conveying process, the push rod 23 is controlled to pull back the front and rear sliding frames 25, the upper and lower sliding frames 12 and the push frame 13. During the movement of the front and rear sliding frames 25, the adjustment sliding rod 30, the extension rod 31 and the sliding block 28 are driven to move horizontally back. The front sliding block 28 is controlled to be in the initial position close to the middle part of the upper part in the limiting chute 27. When the sliding block 28 moves to the inclined groove position on one side, the sliding block 28 will be pulled back horizontally while descending. When the sliding block 28 descends to the lowest point, the process sensor controls the adjustment push rod 23 to change from pulling to pushing, and the sliding block 28 is pushed forward. When the sliding block 28 moves to the other inclined groove and rises to the highest point, the adjustment push rod 23 is controlled to change from pushing to pulling, and the sliding block 28 is reset. The left and right directions of the upper and lower sliding frames 12 and the push frame 13 are fixed relative to the front and rear sliding frames 25. Therefore, the push frame 13 moves synchronously with the sliding block 28. The push frame 13 moves from the position close to the middle part at a high place to the direction of the transformer skeleton on the feeding chute 4, and then descends to the left side of the transformer skeleton. After moving to the left side of the transformer skeleton, the transformer skeleton is pushed to the pin position on the right side. When the transformer skeleton reaches the pin position, the push frame 13 moves upward away from the transformer skeleton, and then resets; S3, after adjusting the position of the transformer skeleton, the clamping push rod 32 can be controlled to rise, and the clamping block 37 is driven to rise. The clamping block 37 drives the transmission arm 38 and the clamping frame 39 to gather in the direction of approaching each other, so as to drive the two clamping plates 41 to approach each other, and finally make the two clamping plates 41 clamp the pin. After clamping, the sliding frame push rod 9 is controlled to descend, and the main sliding frame 8 and the clamping frame 39 are driven to descend, and the pin is driven to descend. At the same time, the push plate 42 below the main sliding frame 8 is driven to descend, and first contacts the two pushed frames 44. Then the two pushed frames 44 are pushed to the opposite directions on both sides at the same time, and the two extension arms 46 connected with the two pushed frames 44 are rotated in the center of the positioning shaft 45 as the center to the opposite directions, so that the two extension arms 46 gradually approach each other. The positioning block 50 on one side of the two extension arms 46 first contacts the transformer skeleton to be inserted, and clamps and positions the transformer skeleton. When clamping and positioning the transformer skeleton, the reset spring 49 is used for buffering the clamping, and the gradually clamping contacts the pressure sensor 48. At this time, the sliding frame push rod 9 descends to the set height, and finally the pressure sensor 48 is delayed to trigger the rotary cutting piece 43 to work to cut off the pin. After cutting off, the process sensor sends a signal to the external controller to control the clamping push rod 32 to descend, and the clamping block 37 is driven to descend. The clamping block 37 drives the transmission arm 38 and the clamping frame 39 to move away from each other, so as to drive the two clamping plates 41 to move away from each other. Finally, the sliding frame push rod 9 is controlled to rise and reset; S4, after the transformer skeleton pin is inserted, the adjusting push rod 23 is continuously controlled to repeat the step S2, another push frame 13 moves along the same track as the feeding push frame 13, but another push frame 13 can push the transformer skeleton after pin insertion to the next step in the same movement state due to the different position, and then the push frame 13 continues to repeat the step S2 to form a cycle, the transformer skeleton after pin insertion is pushed to the position of the detection rod 58, and the detection rod 58 and the alarm lamp 20 are used for detecting the bending degree of the pin, if the pin is bent to contact the detection rod 58 to trigger the detector 55, the alarm lamp 20 is controlled to work through the controller, and the staff can be reminded to process the defective products; S5, the transformer skeleton after the last detection is qualified and is pushed to the bottom of the limiting block 62, the limiting block 62 captures the transmission object through the optical sensor and controls the limiting push rod 18 to work, drives the limiting block 62 to descend, and the limiting block 62 descends first to gradually position and support the transformer skeleton, in the process of positioning and supporting, the inclined surface of the auxiliary bending frame 63 contacts the pin of the transformer skeleton, the pin is pre-bent, and when the limiting push rod 18 descends to the set height, the bending push rod 60 is controlled to work through the process sensor set in advance, drives the bending block 61 to repeatedly ascend and descend, and the pin is further processed by repeated bending.

[0044] The application has the following technical effects.

[0045] 1. The adjusting push rod 23 works to pull back the front and rear sliding frames 25, the upper and lower sliding frames 12 and the push frame 13 by a distance, and after the pull back is finished, the push frame 13 is pushed forward by a distance, the process drives the push frame 13 to first pull back horizontally, then moves horizontally along the inclined groove and descends, and after descending to the appropriate height, the push frame 13 is continuously pushed forward, moves from the position close to the middle of the high place to the direction of the transformer skeleton on the feeding sliding groove 4, then descends and moves to the left side of the transformer skeleton, and after moving to the left side of the transformer skeleton, the transformer skeleton is pushed to the right side, and another push frame 13 at a different position can push the transformer skeleton after pin insertion to the next several links according to the same movement track, only one push rod cooperation structure is needed to realize the steps of feeding and lowering, the waste of resources caused by the large number of push rods in the traditional structure is reduced, and the debugging operation of the equipment is reduced; 2. The application works by sliding the push rod 9 to drive the main sliding frame 8 and the push plate 42 connected below the main sliding frame 8 to descend, the push plate 42 will first contact the two pushed frames 44, and push the two pushed frames 44 to the two sides at the same time, drive the two extension arms 46 connected with the two pushed frames 44 to rotate towards the center of the positioning shaft 45 as the center, so that the two extension arms 46 gradually approach each other, in the approaching process, the two positioning blocks 50 first contact the transformer skeleton to be inserted, and the transformer skeleton is positioned and clamped, reducing the error of the inserted pin material and causing the transformer skeleton pin position to be inaccurate, greatly reducing the waste of raw materials caused by pin errors, and the pressure sensor 48 and the rotary cutting piece 43 are not triggered, reducing the situation that the operation error causes the pin to be cut off and falls into the equipment, affecting the equipment; 3. The detection rod 58 and the alarm lamp 20 can detect the bending degree of the pin, and can solve the problem that when the reserved hole depth of the transformer skeleton is insufficient or the hole position has a large error with the standard requirement, the insertion depth is set as a fixed value, and the pin is easily bent due to the above reasons during insertion. Such detection can assist the alarm to screen out unqualified transformer skeletons.
