Description
Technical Field
[0001] This invention relates to the field of transformer equipment technology, such as intelligent reactors, and particularly to a copper busbar positioning device for processing micro transformers. Background Technology
[0002] Miniature transformers are core components in electronic appliances, precision industrial control equipment, and small-scale new energy devices. During their production, the copper busbar assembly and positioning process directly determines the conductivity, assembly accuracy, and finished product qualification rate of the miniature transformer, making it a critical step in its manufacturing. In the copper busbar installation process, precise alignment, positioning, and fixing of the copper busbar to the miniature transformer are essential to ensure consistency in the installation position, angle, and height of the copper busbar. This guarantees the stability and reliability of subsequent electrical connections within the miniature transformer.
[0003] Currently, existing positioning equipment for micro-transformer copper busbar processing suffers from numerous technical shortcomings in practical use. Firstly, traditional positioning devices offer poor limiting effects on the copper busbar, mostly only capable of limiting one or both sides, failing to simultaneously limit and fix all four ends of the busbar. This leads to displacement, wobbling, and misalignment after placement, easily causing subsequent assembly deviations and significantly reducing processing accuracy. Secondly, existing equipment lacks a precise alignment and aiming structure, relying heavily on manual visual observation or simple rulers to align the copper busbar with the micro-transformer. This results in low positioning efficiency, significant errors, and an inability to achieve rapid and accurate aiming and positioning of the copper busbar, making it difficult to meet the demands of refined, mass-production processing of micro-transformers.
[0004] Third, existing positioning devices have poor adaptability and versatility. Most can only fix and position micro-transformers of a single specification, failing to meet the processing needs of micro-transformers of various sizes, thus limiting the equipment's applicability. Furthermore, traditional fixing structures do not provide comprehensive positioning for micro-transformers, making it difficult to achieve omnidirectional positioning and fixing. During processing, micro-transformers are prone to displacement and deflection, severely affecting the assembly accuracy of the copper busbars. Finally, existing equipment lacks sufficient adjustability. After the micro-transformer is installed and fixed, its installation angle and height cannot be flexibly adjusted, making it difficult to adapt to different processing techniques and assembly standards. The equipment's processing flexibility and practicality are poor, greatly restricting the production efficiency and finished product quality of micro-transformer copper busbar processing, and failing to meet the current demand for high-precision, diversified, and mass-produced micro-transformer processing.

Guide rods and return springs are embedded in the left and right ends inside the upper guide frame and the upper and lower ends inside the side guide frames. A guide cylinder is nested on the outside of the guide rod, and a guide wheel is embedded between the two guide cylinders. An upper line laser strip and a side line laser strip are respectively installed on the outside of the guide cylinders embedded in the upper guide frame and the side guide frame through brackets. A lower line laser strip is installed below the rear end of the lower guide plate.
[0012] Preferably, the outer wall of the push plate is in close contact with the upper surface of the inner wall of the feeding tray and the upper surface of the lower guide plate. The push plate slides back and forth horizontally on the upper surface of the lower guide plate. A stepped groove is provided on the bottom right side of the push plate from bottom to top.
[0013] Preferably, the guide wheel in the upper guide frame drives the guide cylinder to slide horizontally left and right along the guide rod in the side guide frame, and the guide wheel in the side guide frame drives the guide cylinder to slide vertically up and down along the guide rod.
[0014] Preferably, the bottom of the upper line laser strip and the bottom of the guide wheel in the upper guide plate are at the same horizontal height, the upper surface of the lower guide plate and the top of the lower line laser strip are at the same horizontal height, and the end of the side line laser strip near the middle of the lower guide plate and the guide cylinder are at the same longitudinal horizontal plane.
[0015] Preferably, the rightmost end of the feeding tray is provided with a discharge port, and the upper line laser strip, the lower line laser strip and the two side line laser strips synchronously project line lasers to the right, and the four laser lines are connected to each other to form a hollow rectangular laser outline.
[0016] This invention provides a copper busbar positioning device for processing miniature transformers, which has the following advantages: 1. After the copper busbar is placed inside the feeding tray, the multi-stage electric push rod drives the push plate to transport the copper busbar to the right, so that the copper busbar extends into the area between the upper guide plate and the lower guide plate. When the copper busbar abuts against the guide wheel at the bottom of the upper guide frame, the guide wheel is driven by force to make the guide cylinder and the upper I-line laser strip connected to the right side of the guide cylinder slide upward along the guide rod. When the copper busbar contacts the guide wheel of the side guide frame, the guide wheel pushes the corresponding guide cylinder and the side I-line laser strip connected to the right side of the guide cylinder to slide back and forth along the guide rod. After being constrained by the upper guide frame and the side guide frame, the copper busbar is tightly attached to the upper surface of the lower guide plate and is centered. The lower guide plate is located in the middle, thus simultaneously completing the four-way limiting and fixing of the copper busbar in the upper, lower, left, and right directions, effectively preventing the copper busbar from shifting, shaking, or misaligning after placement. At the same time, the upper line laser bar, the lower line laser bar, and the two side line laser bars simultaneously project line laser beams to the right. The four laser lines connect end to end to form a hollow rectangular laser outline of the same size as the copper busbar, which is then projected onto the copper busbar installation position of the micro transformer. This enables rapid and accurate alignment and aiming of the copper busbar installation position, meeting the high-precision operation requirements of the refined and mass production of micro transformers.
[0017] 2. After the miniature transformer is placed on the workbench, the auxiliary electric push rod pulls two auxiliary limiting plates to move synchronously towards the center of the support plate, and the main electric push rod pulls two main limiting plates to move synchronously towards the center of the support plate. The two auxiliary limiting plates and the two main limiting plates are respectively attached to the left and right sides and the front and rear sides of the miniature transformer, which can be used to position and process miniature transformers of different shapes and sizes. Then, the hydraulic cylinder drives the connecting column to move the limiting plate downward, so that the limiting plate presses against the upper surface of the miniature transformer. Together with the support plate below, the miniature transformer is fixed in both directions. Through the above-mentioned six-sided constraint structure (front, back, left, right, top, and bottom), displacement and deflection of the miniature transformer during processing can be effectively prevented, significantly improving the alignment accuracy of the copper busbar assembly. During the assembly operation, the matching electric push rod can be controlled to drive the support plate and the miniature transformer to rise and fall as a whole through the snap ring according to the processing requirements, so as to complete the workpiece height adjustment; the stepper motor drives the support plate and the miniature transformer to rotate through the transmission column, thereby adjusting the assembly angle of the miniature transformer relative to the copper busbar. The equipment is flexible in adjustment and greatly improves the convenience of assembly operation. Attached Figure Description

Detailed Implementation
[0020] Example 1, referring to Figure 1-11 A copper busbar positioning device for processing miniature transformers includes a worktable 1 and a support frame 5. The support frame 5 is fixed to the rear end of the upper surface of the worktable 1. A mounting plate 2 is fixed to the middle of the bottom end of the worktable 1. A stepper motor 201 is fixed to the lower part inside the mounting plate 2. A transmission column 202 is installed on the top of the transmission shaft at the power output end of the stepper motor 201. Electric push rods 203 are vertically fixed to the left and right ends inside the mounting plate 2. The push rods at the power output ends of the two electric push rods 203 are fitted with snap rings 204. A support plate 205 is nested on the upper part of the outer side of the transmission column 202. Both ends of the mounting plate 2 are open to the transmission column 202. A main electric push rod 3 is longitudinally fixed to the bracket. The outer side of the push rod at the power output end of the two main electric push rods 3 is connected to a main limiting plate 301. The front and rear ends of the mounting plate 2 are laterally fixed to auxiliary electric push rods 4 through the bracket. The outer side of the push rod at the power output end of the two auxiliary electric push rods 4 is connected to an auxiliary limiting plate 401. A hydraulic cylinder 501 is vertically fixed to the top front end of the support frame 5. A connecting column 502 and a return spring 503 are embedded below the push rod at the power output end of the hydraulic cylinder 501. A limiting plate 504 is nested below the outer side of the connecting column 502. A positioning component is provided in the middle of the front end of the main limiting plate 301.
[0021] The center of the limiting plate 504 and the center of the support plate 205 are both on the same vertical horizontal plane. The limiting plate 504 is set directly above the support plate 205. The upper surface of the support plate 205 and the upper surface of the worktable 1 are both on the same horizontal plane. When the miniature transformer is positioned between the two main limiting plates 301 and the two auxiliary limiting plates 401, the hydraulic cylinder 501 pushes the connecting column 502 and the limiting plate 504 to move downward, so that the limiting plate 504 is in close contact with the upper surface of the miniature transformer to limit and fix the upper and lower ends of the miniature transformer. During the processing, the miniature transformer is not easy to move or deflect, which effectively improves the assembly accuracy of the copper busbar. When the miniature transformer is positioned between the support plate 205 and the limiting plate 504, the support plate 205 can still drive the miniature transformer and the limiting plate 504 to rotate around the outside of the connecting column 502 above it. During assembly, the electric push rod 203 can be used to push the micro transformer up and down through the snap ring 204 and the support plate 205 to adjust the height of the micro transformer, or the stepper motor 201 can be used to drive the support plate 205 and the micro transformer to rotate through the transmission column 202 to adjust the installation angle between the micro transformer and the copper busbar. It has a high degree of flexibility. The limiting plate 504 rotates horizontally on the outside of the connecting column 502, and the connecting column 502 moves vertically up and down below the push rod of the hydraulic cylinder 501. The cross-sectional area of the limiting plate 504 is the same as that of the supporting plate 205. Two secondary limit plates 401 and the main electric push rod 3 are respectively set on the left and right ends and the front and rear ends above the support plate 205. The two secondary limit plates 401 are respectively embedded in the left and right ends inside the main limit plate 301. When the miniature transformer is placed on the upper surface of the workbench 1, the auxiliary electric push rod 4 pulls the two auxiliary limit plates 4 to move towards the center of the support plate 205 at the same time, and the main electric push rod 3 pulls the two main limit plates 301 to move towards the center of the support plate 205 at the same time, so that the two auxiliary limit plates 401 and the two main limit plates 301 are in close contact with the left, right and front and rear ends of the miniature transformer at the same time, which can meet the processing needs of miniature transformers of various sizes and specifications. A retaining ring groove is provided on the lower outer side of the support plate 205, and the retaining ring 204 is embedded in the retaining ring groove. The support plate 205 rotates horizontally on the outer side of the retaining ring 204, and the transmission column 202 is embedded in the lower inner side of the support plate 205. When the support plate 205 moves up and down outside the transmission column 202, the stepper motor 201 can still drive the support plate 205 at any height to rotate through the transmission column 202. The main function of the snap ring 204 is to support the rotation of the support plate 205. During the rotation of the support plate 205, the electric push rod 203 can still push the support plate 205 to move up and down normally through the snap ring 204.
[0022] Example 2 differs from Example 1 in that, in this example, the positioning assembly consists of a feeding tray 6, a guide tray 601, a multi-stage electric push rod 602, a push plate 603, an upper guide plate 7, a lower guide plate 8, an upper guide frame 9, a side guide frame 10, a guide rod 11, a return spring 12, a guide cylinder 13, a guide wheel 14, a lower single-line laser strip 15, a side single-line laser strip 16, and an upper single-line laser strip 17. A feeding plate 6 is longitudinally fixed at the front center of the main limiting plate 301. A guide plate 601 is installed on the top of the feeding plate 6. A multi-stage electric push rod 602 is fixed inside the front of the feeding plate 6. A push plate 603 is installed at the rear end of the push rod at the power output end of the multi-stage electric push rod 602. An upper guide plate 7 and a lower guide plate 8 are respectively installed at the upper and lower ends inside the feeding plate 6. An upper guide frame 9 is fixed at the bottom of the upper guide plate 7. Side guide frames 10 are symmetrically fixed at the left and right ends inside the lower guide plate 8. Guide rods 11 and return springs 12 are embedded in the left and right ends inside the upper guide frame 9 and the upper and lower ends inside the side guide frame 10. A guide cylinder 13 is nested on the outside of the guide rod 11. A guide wheel 14 is embedded between the two guide cylinders 13. An upper line laser strip 17 and a side line laser strip 16 are respectively installed on the outside of the guide cylinders 13 embedded in the upper guide frame 9 and the side guide frame 10 through brackets. A lower line laser strip 15 is installed below the rear end of the lower guide plate 8. The outer wall of the push plate 603 is in close contact with the upper part of the inner wall of the feeding tray 6 and the upper surface of the lower guide plate 8. The push plate 603 slides back and forth horizontally on the upper surface of the lower guide plate 8. A stepped groove is provided on the bottom right side of the push plate 603 from bottom to top. When the pusher plate 603 pushes the copper busbar to the right, the copper busbar will be embedded in the stepped slot. The slot can limit the copper busbar of various thicknesses and prevent it from shaking as it slides to the right along the feed tray 6. The guide wheel 14 in the upper guide frame 9 drives the guide cylinder 13 to slide horizontally left and right along the guide rod 11 in the side guide frame 10, and the guide wheel 14 in the side guide frame 10 drives the guide cylinder 13 to slide vertically up and down along the guide rod 11. The multi-stage electric push rod 602 pushes the push plate 603 and the copper busbar to move to the right and enter the lower part of the upper guide plate 7 and the middle part of the lower guide plate 8. After the copper busbar contacts the guide wheel 14 below the upper guide frame 9, the guide wheel 14 pushes the guide cylinder 13 to move upward along the guide rod 11. After the copper busbar contacts the guide cylinder 13 on the side guide frame 10, the guide wheel 14 pushes the guide cylinder 13 to move forward and backward along the guide rod 11. At this time, the copper busbar is tightly attached to the bottom of the guide wheel 14 of the lower guide plate 8 after being constrained by the upper guide frame 9 and the side guide frame 10, and is centered in the middle of the lower guide plate 8. Thus, the copper busbar is simultaneously limited and fixed in four directions (upper, lower, left, and right), effectively preventing the copper busbar from shifting, shaking, or misaligning after placement. The bottom of the upper line laser strip 17 and the bottom of the guide wheel 14 in the upper guide plate 7 are at the same horizontal height. The upper surface of the lower guide plate 8 and the top of the lower line laser strip 15 are at the same horizontal height. The end of the side line laser strip 16 near the middle of the lower guide plate 8 and the guide cylinder 13 are at the same longitudinal horizontal plane. The rightmost end of the feeding tray 6 has a discharge port. The upper line laser strip 17, the lower line laser strip 15 and the two side line laser strips 16 simultaneously project line laser lines to the right. The four laser lines are connected to each other to form a hollow rectangular laser outline. The upper line laser bar 17, the lower line laser bar 15, and the two side line laser bars 16 simultaneously project line laser beams to the right. The four laser lines connect end to end to form a hollow rectangular laser outline, which is then projected onto the copper busbar installation station of the micro transformer. This enables rapid and accurate alignment and aiming of the copper busbar installation position, meeting the high-precision operation requirements of the fine and mass production of micro transformers. When the bottom guide wheel 14 of the upper guide frame 9 is in contact with the top surface of the copper busbar and the front and rear guide wheels 14 of the side guide frame 10 are in contact with the front and rear end surfaces of the copper busbar for adaptive positioning, the upper line laser strip 17 and the two side line laser strips 16 follow the copper busbar synchronously with the guide wheel 14 to complete the up-down and back-forward adjustment, so that the hollow rectangular outline formed by the laser projection matches the actual external size of the current copper busbar in real time. The laser positioning outline can automatically adapt to copper busbars of different thicknesses and widths without the need for manual calibration of the laser position. It always ensures that the rectangular laser outline is accurately aligned with the side of the copper busbar, which greatly improves the adaptability and alignment efficiency of positioning and aiming of copper busbars of different specifications.
[0023] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
