Description

Technical Field

[0001] The present invention relates to the technical field of transformer processing, in particular to a copper busbar positioning device for processing a micro transformer. Background Art

[0002] A micro transformer is a small, low-power transformer suitable for high frequencies or special scenarios. It is mainly used for signal processing, power conversion, isolation or impedance matching.

[0003] During the assembly of a micro-transformer, in order to ensure the connection of the lines, copper busbars need to be installed on the transformer body. Currently, the assembly of the busbars requires manually inserting the busbars into the wiring slots on the transformer body, and then fixing the busbars in the wiring slots with bolts. However, in order to protect the connection of the cables, some wiring slots are tubular in shape. When the busbars are tightened with bolts, the internal connection screw holes cannot be directly seen, causing the operator to repeatedly fine-tune the position of the busbars. This increases the operator's labor intensity in the long run and affects the assembly efficiency of the transformer. Therefore, a busbar positioning device for micro-transformer processing is proposed to solve the above problems. Summary of the Invention

[0004] The present invention addresses the defect in the prior art that when a copper busbar is locked by bolts, the internal connecting screw holes cannot be directly seen, resulting in the operator having to repeatedly fine-tune the position of the copper busbar. This increases the operator's labor intensity in the long run and affects the assembly efficiency of the transformer. A copper busbar positioning device for micro-transformer processing is provided.

[0005] The present invention is achieved through the following technical solutions:

[0006] A copper busbar positioning device for processing a micro transformer includes a base plate for positioning a transformer body, a positioning mechanism for pushing the copper busbar into a wiring slot at the upper end of the transformer body being installed on the base plate via a support frame;

[0007] The positioning mechanism includes a mounting plate and a plurality of feeding mechanisms fixed on the mounting plate, the feeding mechanism includes a feeding trough aligned with the wiring trough, and a feeding channel is provided at the upper end of the feeding trough;

[0008] A positioning plate is slidably installed inside the feed trough, and a push block is provided at one end of the feed trough away from the wiring trough to push the positioning plate to move. The positioning plate is used to carry the copper busbar to move into the wiring trough and position the copper busbar in the wiring trough.

[0009] In a preferred embodiment of the present invention, the number of the feeding mechanisms is the same as the number of the wiring slots, and the feeding mechanisms are linearly arranged on the mounting plate. The copper busbar is pushed into the wiring slot by the feeding mechanisms corresponding to the wiring slots, and then the copper busbar is fixed in the wiring slots by bolts.

[0010] In a preferred embodiment of the present invention, a blanking port is provided at the top of the feed trough, and the blanking channel includes four guide columns vertically fixed around the blanking port, and the guide columns are fixed in the middle of the edge of the blanking port. The copper busbars are stacked in the blanking channel and pushed into the wiring trough in sequence by the feeding mechanism for installation.

[0011] In a preferred embodiment of the present invention, a pushing cylinder is provided at one end of the feeding trough away from the wiring trough, and the telescopic end of the pushing cylinder is fixedly connected to the pushing block, and the pushing cylinder pushes the pushing block to move a certain distance.

[0012] In a preferred embodiment of the present invention, the vertical cross-section of the push block is "L"-shaped, and a contact switch is installed at the lower end of the push block, and a slide groove is opened in the vertical direction on the inner wall of the push block, and a T-shaped slider is provided in the slide groove. The outer end of the T-shaped slider is rotatably connected to the positioning plate. After the positioning plate is rotatably connected, when the copper busbar is pushed into the wiring slot, the left and right positions of the copper busbar can be fine-tuned when the second positioning spring is clamped in the copper busbar mounting hole in the wiring slot, so that the position of the through hole on the copper busbar is aligned with the copper busbar mounting hole in the wiring slot.

[0013] In a preferred embodiment of the present invention, the vertical section of the positioning plate is U-shaped, and the upper end plate at the opening of the positioning plate is rotatably connected to the T-shaped slider through a bearing, and the length of the lower end plate is smaller than that of the upper end plate.

[0014] In a preferred embodiment of the present invention, a through-hole is provided on the positioning plate, which passes through the upper and lower plate bodies, and a first positioning spring piece protruding from the upper end is provided in the through-hole of the upper plate body, and a second positioning spring piece protruding from the lower end is provided in the through-hole of the lower end. Installation slots are provided on the inner walls of both sides of the two through-holes, and both ends of the first positioning spring piece and the second positioning spring piece are inserted into the installation slots and slidably cooperate with the installation slots. The first positioning spring piece positions the position of the copper busbar on the positioning plate and reduces the displacement of the copper busbar during the pushing process. After entering the wiring slot, the second positioning spring piece is clamped in the copper busbar mounting hole in the wiring slot to position the positioning plate, thereby aligning the position of the through-hole on the copper busbar with the copper busbar mounting hole in the wiring slot.

[0015] In a preferred embodiment of the present invention, limit strips are provided on both sides of the upper surface of the first positioning spring piece, and the two ends of the first positioning spring piece are arranged horizontally, and the two ends of the second positioning spring piece are provided with baffles, the height of the baffles is greater than the height of the two ends of the first positioning spring piece and is located on the outside thereof. In the process of inserting the bolt to fix the copper busbar, the end of the bolt pushes the first positioning spring piece to move downward, so that the protruding end of the bolt moves downward out of the through hole on the copper busbar, and the two ends of the first positioning spring piece extend outward to stretch the second positioning spring piece, so that the protruding part of the second positioning spring piece is separated from the copper busbar mounting hole in the wiring slot, which is convenient for the subsequent resetting of the positioning plate, and after the first positioning spring piece moves a certain distance, the limit strip reaches the mounting slot, and when the bolt continues to press, the upper plate body of the positioning plate is driven to bend and deform downward, so that the end of the positioning plate contacts the contact switch, triggering the reset operation of the push cylinder, and then driving the positioning plate to reset.

[0016] In a preferred embodiment of the present invention, the positioning plate is made of elastic metal, which is convenient for resetting after pressing the positioning plate.

[0017] In a preferred embodiment of the present invention, mounting holes are provided at the four corners of the base plate, and the upper surface of the base plate is provided with limiting grooves adapted to the upper legs of the transformer body to position the transformer body and prevent the transformer from moving when pushing the copper busbar.

[0018] The beneficial effects of the present invention are:

[0019] 1. This device pushes the copper busbar into the wiring slot through the push cylinder. At the same time, the through hole on the copper busbar and the mounting screw hole inside the wiring slot are positioned by the first and second positioning springs so that they are on the same vertical line, thereby avoiding the operator from repeatedly fine-tuning the position of the copper busbar, facilitating the insertion of bolts and fixing the copper busbar.

[0020] 2. This device sets a feeding channel so that the copper bar falls from the feeding channel to the positioning plate in the feeding trough in sequence, and the first positioning spring performs preliminary positioning on the copper bar, thereby avoiding displacement of the copper bar during the pushing process and improving its positioning accuracy.

[0021] 3. During the process of fixing the copper busbar, when the bolt is inserted, the bolt squeezes the first positioning spring. Since the positioning plate is a double-layer setting, when the first positioning spring is squeezed to a certain extent, it drives the open end of the upper positioning plate to press down, so that it touches the contact switch, and then the push cylinder retracts, driving the positioning plate to automatically retract, avoiding the positioning plate from interfering with the fixation of the copper busbar, and facilitating the next copper busbar positioning operation.

[0030] The following detailed description of preferred embodiments of the present invention is provided in conjunction with the accompanying drawings to facilitate understanding of the advantages and features of the present invention by those skilled in the art, thereby providing a clearer and more precise definition of the scope of protection of the present invention. Directional terms used in the present invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are intended solely to refer to the directions of the accompanying drawings. Therefore, the directional terms used are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0031] like Figure 1-7 The copper busbar positioning device for micro transformer processing shown in the figure includes a base plate 1 for positioning the transformer body 4. The four corners of the base plate 1 are provided with mounting holes for fixing the base plate 1, and the upper surface of the base plate 1 is provided with a limiting groove 2 adapted to the upper leg of the transformer body 4. Figure 1 As shown, the transformer body 4 is placed on the bottom plate 1 and positioned to prevent the transformer from moving when pushing the copper busbar;

[0032] A positioning mechanism 5 is installed on the bottom plate 1 through the support frame 3 to push the copper bar into the wiring slot 41 at the upper end of the transformer body 4;

[0033] The positioning mechanism 5 includes a mounting plate 51 and a plurality of feeding mechanisms 52 fixed to the mounting plate 51. The feeding mechanisms 52 include feeding slots 521 aligned with the wiring slots 41. The number of feeding mechanisms 52 is the same as the number of wiring slots 41, and the feeding mechanisms 52 are linearly arranged on the mounting plate 51. The copper busbar is pushed into the wiring slot 41 by the feeding mechanisms 52 corresponding to the wiring slots 41, and then the copper busbar is fixed to the wiring slot 41 by bolts.

[0034] The upper end of the feed trough 521 is provided with a feed channel 6, and a feed opening 522 is opened at the top of the feed trough 521. The feed channel 6 includes four guide posts 61 vertically fixed around the feed opening 522. The guide posts 61 are fixed in the middle of the edge of the feed opening 522. By stacking the copper bars in the feed channel 6, the feeding mechanism 52 pushes them into the wiring slot 41 in sequence for installation.

[0035] Secondly, a positioning plate 524 is slidably installed inside the feed trough 521, and a push block 523 is provided at the end of the feed trough 521 away from the wiring trough 41 to push the positioning plate 524 to move. The positioning plate 524 is used to carry the copper bar to move into the wiring trough 41 and position the copper bar in the wiring trough 41. A pushing cylinder 529 is provided at the end of the feed trough 521 away from the wiring trough 41. The telescopic end of the pushing cylinder 529 is fixedly connected to the pushing block 523, and the pushing cylinder 529 pushes the pushing block 523 to move a certain distance.

[0036] Assuming that the distance between the outer end of the push block 523 and the copper busbar through-hole in the wiring slot 41 is X, and the distance between the push block 523 and the protrusion center of the first positioning spring 526 is Y, the moving distance of the push cylinder 529 to push the push block 523 is XY.

[0037] It should be noted that the vertical cross-section of the push block 523 is "L"-shaped, and a contact switch 5232 is installed at the lower end of the push block 523, and a slide groove 5231 is provided in the vertical direction on the inner wall of the push block 523, and a T-shaped slider 528 is provided in the slide groove 5231. The outer end of the T-shaped slider 528 is rotatably connected to the positioning plate 524. The vertical cross-section of the positioning plate 524 is "U"-shaped, and the upper end plate at the opening of the positioning plate 524 is rotatably connected to the T-shaped slider 528 through a bearing. The length of the lower end plate is smaller than the length of the upper end plate. After the positioning plate 524 is rotated and connected, when the copper busbar is pushed into the wiring slot 41, the left and right positions of the copper busbar can be fine-tuned when the second positioning spring piece 527 is clamped in the copper busbar mounting hole in the wiring slot 41, so that the position of the through hole on the copper busbar is aligned with the copper busbar mounting hole in the wiring slot 41.

[0038] Specifically, the positioning plate 524 is made of elastic metal, such as one of spring steel, stainless steel, titanium alloy, and copper alloy, so that it is easy to reset after pressing the positioning plate 524. A through hole 525 is opened on the positioning plate 524, and the through hole 525 passes through the upper and lower plate bodies. A first positioning spring piece 526 protruding from the upper end is provided in the through hole 525 of the upper end plate body, and a second positioning spring piece 527 protruding from the lower end is provided in the through hole 525 of the lower end plate body. The center of the first positioning spring piece 526 and the center of the second positioning spring piece 527 are on the same vertical line. Mounting slots 5251 are opened on the inner walls of both sides of the two through holes 525. Both ends of the first positioning spring piece 526 and the second positioning spring piece 527 are inserted into the mounting slot 5251 and slidably fit with the mounting slot 5251.

[0039] The first positioning spring piece 526 positions the copper busbar on the positioning plate 524 and reduces the displacement of the copper busbar during the pushing process. The second positioning spring piece 527 is engaged with the copper busbar mounting hole in the wiring slot 41 after entering the wiring slot 41, positioning the positioning plate 524, and then aligning the position of the through hole on the copper busbar with the copper busbar mounting hole in the wiring slot 41.

[0040] At the same time, limit strips 5261 are provided on both sides of the upper surface of the first positioning spring piece 526, and the two ends of the first positioning spring piece 526 are arranged horizontally, and the two ends of the second positioning spring piece 527 are provided with baffles 5271. The height of the baffles 5271 is greater than the height of the two ends of the first positioning spring piece 526 and is located outside thereof. In the process of inserting the bolt to fix the copper bar, the end of the bolt pushes the first positioning spring piece 526 to move downward, so that its protruding end moves downward out of the through hole on the copper bar. The two ends of the first positioning spring piece 526 extend outward to stretch the second positioning spring piece 527, so that its protruding part disengages from the copper bar mounting hole in the wiring groove 41, facilitating the subsequent reset of the positioning plate 524. After the first positioning spring piece 526 moves a certain distance, the limit strips 5261 reach the mounting notch 5251. When the bolt continues to be pressed, the upper plate body of the positioning plate 524 is bent and deformed downward, so that its end contacts the contact switch 5232, triggering the reset operation of the pushing cylinder 529, thereby driving the positioning plate 524 to reset.

[0041] In this embodiment, when using this device, if Figure 1 As shown, the transformer body 4 is placed on the base plate 1, and the copper bars are stacked in each feed channel 6;

[0042] The copper busbar falls through the drop opening 522 into the positioning plate 524 in the feeding trough 521 (the feeding trough 521 can only accommodate one copper busbar). When the copper busbar is located on the positioning plate 524, the raised end of the first positioning spring 526 is engaged with the through hole on the copper busbar.

[0043] The push cylinder 529 is turned on, and the push cylinder 529 pushes the positioning plate 524 to move into the wiring slot 41, and at the same time drives the copper busbar to move. After moving a specified distance, the second positioning spring piece 527 is engaged with the copper busbar mounting hole in the wiring slot 41. During the engaging process, the positioning plate 524 can be driven to rotate on the T-shaped slider 528, and the left and right position of the positioning plate 524 can be fine-tuned and positioned. Since the center of the first positioning spring piece 526 and the center of the second positioning spring piece 527 are on the same straight line, the position of the through hole on the copper busbar is aligned with the copper busbar mounting hole in the wiring slot 41.

[0044] When the copper busbar is fixed in the wiring slot 41 by using bolts, the bolts are first inserted into the through holes on the copper busbar. At this time, the bottom end of the bolt pushes the raised end of the first positioning spring piece 526, pushing the first positioning spring piece 526 to move downward, so that the raised end moves downward out of the through hole on the copper busbar. At the same time, the two ends of the first positioning spring piece 526 extend outward to squeeze and stretch the second positioning spring piece 527, so that the raised part of the second positioning spring piece 527 is separated from the copper busbar mounting hole in the wiring slot 41, which is convenient for the subsequent resetting of the positioning plate 524. After the first positioning spring piece 526 moves a certain distance, the limit bar 5261 reaches the mounting slot 5 251. As the bolt continues to be pressed, the upper plate of the positioning plate 524 is bent and deformed downward, so that its end contacts the contact switch 5232, triggering the reset operation of the push cylinder 529, and then driving the positioning plate 524 to reset. Since the bolt is inserted into the through hole of the copper busbar, during the reset process of the positioning plate 524, the copper busbar is limited by the bolt to prevent it from moving. After the positioning plate 524 is reset, the bolt continues to be inserted and installed into the fixing hole in the wiring slot 41, thereby avoiding the operator from repeatedly fine-tuning the position of the copper busbar, facilitating the insertion of the bolt and fixing the copper busbar.
