Description

TECHNICAL FIELD

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

[0002] The transformer skeleton, also known as a transformer frame, is a core insulation and structural support component of a transformer, which is usually made of engineering plastics (such as nylon, PBT, epoxy resin, etc.) with excellent high-temperature resistance and insulation performance by injection molding. The main function of the transformer skeleton is to provide a winding carrier for the transformer winding. Through the pre-set line groove and pin groove structure, the winding is arranged in order, 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 excellent 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] When assembling the pins of the transformer skeleton, a pin inserting machine is needed to assist in pin inserting. When the pin inserting machine is used for pin inserting and discharging of the transformer skeleton, the transformer skeleton needs to be pushed to the pin inserting position of the feeding frame first, then the pushing frame is raised away from the transformer skeleton, and after the pin inserting is completed, the pushing frame is lowered again, and the pushing control is matched to realize the pin inserting feeding and discharging of the transformer skeleton. Although this matching can realize the pin inserting feeding and discharging of the transformer skeleton, in actual use, the above steps need to be completed by multiple cylinders according to the set steps. The cooperation of multiple devices will waste resources, and the operator needs to debug and correct a lot 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. 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 inserting position is not fed, and the pin inserting 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.

[0019] 1. The present application adjusts the push rod to work back and forth, and the sliding frame, the upper and lower sliding frames and the pushing frame are pulled back and forth by a distance, and the pushing frame is pushed forward by a distance after the pulling back is completed. This process drives the pushing frame to move horizontally first, then moves horizontally and downward along the inclined chute, and continues to push forward after descending to the appropriate height.

[0021] 3.

[0039] In this embodiment, before the pin insertion operation is performed on the transformer frame, the sliding block 28 is located in the initial position near the middle of the upper part in the limiting sliding groove 27. The transformer frame is first pushed to the feeding sliding groove 4 by the vibration feeder 3. At this time, the adjusting push rod 23 is controlled to pull back the front and rear sliding frame 25, the upper and lower sliding frame 12 and the push frame 13. During the movement of the front and rear sliding frame 25 back, the adjusting sliding rod 30, the extension rod 31 and the sliding block 28 are all moved back horizontally.

During the movement to the left side of the transformer frame, the transformer frame is pushed to the right side for a distance and then is separated upward from the transformer frame, so as to realize the pin insertion feeding of the transformer frame.

[0042] In this embodiment, during the actual pin insertion work on the transformer frame, the clamping push rod 32 can be controlled to rise first, driving the clamping block 37 to rise, and the clamping block 37 drives the transmission arm 38 and the clamping frame 39 to gather in the direction of approaching each other, thereby driving the two clamping plates 41 to approach each other, and the two clamping plates 41 hold the pin in place.

[0050] 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;

[0051] 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 adjusting sliding rod 30, the extension rod 31 and the sliding block 28 are driven to move back horizontally. 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 is pulled back horizontally while descending. When the sliding block 28 descends to the lowest point, the process sensor controls the adjusting 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 adjusting 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 along with the synchronous displacement of 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 is reset;

[0052] 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 through levers are rotated in the direction of approaching each other with the center of the positioning shaft 45 as the center, 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 the transformer skeleton is clamped and positioned, 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 in the direction of moving 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;

[0053] S4, after the completion of the transformer skeleton pin, at this time continue to control the adjustment of the push rod 23 to repeat S2 step, another pusher 13 moves the same trajectory as the pusher 13 of the feeding, but because of the different positions, another pusher 13 can move in the same movement state to push the transformer skeleton after the pin to the next step, and then the pusher 13 continues to repeat S2 step to form a cycle, the transformer skeleton after the pin will be pushed to the position of the detection rod 58, with the help of two detection rods 58 and the alarm lamp 20, the detection rod 58 is detected, if the pin is bent to contact the detection rod 58 to trigger the detector 55, the controller controls the alarm lamp 20 to work, reminding the staff to handle the defective product;

[0054] S5, the last detection qualified transformer skeleton is pushed to the bottom of the limiting block 62, the limiting block 62 captures the transmission object by optical sensor and controls the limiting push rod 18 to work, drives the limiting block 62 to descend, 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 process sensor is controlled to work, the bending push rod 60 is controlled to work, drives the bending block 61 to repeatedly ascend and descend, and the pin is further processed by repeatedly bending multiple times.

[0055] The present application has the following technical effects.

[0056] 1. The present application adjusts the push rod 23 to work back and forth to pull the front and rear sliding frame 25, the upper and lower sliding frame 12 and the pusher 13 a distance, and after the back and forth pulling is finished, the pusher 13 is pushed forward a distance, this process drives the pusher 13 to first pull back horizontally, then moves back horizontally while descending along the inclined groove, and continues to push forward after descending to the appropriate height, the pusher 13 moves from the high position close to the middle position to the direction of the transformer skeleton on the feeding chute 4, and then moves downward to the left side of the transformer skeleton, and after moving to the left side of the transformer skeleton, drives the transformer skeleton to push to the right side, while another pusher 13 at a different position can move the transformer skeleton after the pin to the next several links according to the same moving track, only one push rod cooperation structure is needed to realize the feeding lifting and discharging steps, which reduces the waste of resources caused by the need for a large number of push rods to be used in the traditional structure, and reduces the debugging operation of the equipment;

[0057] 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 in the opposite direction with 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 pin feeding to cause the transformer skeleton pin position inaccurate, greatly reducing the raw material waste caused by pin failure, and the pressure sensor 48 and the rotary cutting piece 43 are controlled, when the material is not fed to the pin position in time, the positioning block 50 will not be extruded, and the pressure sensor 48 and the rotary cutting piece 43 will not be triggered, reducing the situation that the pin is cut off and falls into the equipment to affect the equipment due to operation error.

[0058] 3. The application detects the degree of bending of the pin through the detection rod 58 and the alarm lamp 20, which can solve the problem that 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, the pin is easily bent due to the fixed value of the insertion depth, so the detection can assist the alarm to screen out unqualified transformer skeletons.
