Description

Technical Field

[0001] This invention relates to the field of small transformer processing technology, and more specifically to automatic bushing equipment for small transformer lead wires. Background Technology

[0002] With the trend of miniaturization and integration of electronic devices, small transformers, as core power distribution components, are widely used in home appliances, communication equipment, industrial control and other fields. The level of automation and product consistency in their manufacturing directly affects the reliability and production efficiency of terminal equipment. Lead-out bushing is a key process in the production of small transformers. It mainly involves installing and fixing insulating bushings on the outside of the conductors to achieve insulation protection, anti-pulling and neat wiring functions, thus ensuring the electrical performance and service life of the transformer.

[0003] Currently, the operation of bushings for small transformer leads still faces many technical bottlenecks: During storage and transportation, bushings are easily flattened and deformed due to compression and bending, resulting in reduced compatibility with conductors, making subsequent assembly difficult, and even requiring secondary manual correction, further reducing production efficiency. Existing equipment lacks a targeted bushing pretreatment structure, making it difficult to effectively repair deformed bushings, resulting in a low assembly qualification rate. At the same time, after the bushing and conductor are assembled, the lack of positioning measures between the two makes it easy for the actual position of the bushing to deviate due to the traction of the processing components, causing the assembly position between the bushing and the small transformer to be misaligned, affecting production quality. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic bushing device for small transformer leads, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatic bushing device for small transformer leads includes: a base; a loading unit, including a top plate mounted on the base and a guide support plate fixed to the bottom of the top plate for storing and guiding bushings and conductors; a conveying assembly, including a mounting frame slidably mounted on the top plate via a movable component to achieve bushing movement adjustment, and mounting covers and connectors respectively fixed to both sides of the mounting frame; wherein, a gear set for clamping and conveying bushings is rotatably mounted inside the mounting cover, and the bushings, after being heated, are output by the connector to a cutting component in the packing unit for segmented cutting; the packing unit includes a push-pull connecting frame slidably mounted on the guide support plate, The assembly includes a kit connecting frame fixed to the front side of the push-pull connecting frame, a kit die head elastically connected to the kit connecting frame, and a glue guiding assembly. The kit die head has an installation cavity, with its top and bottom connected to an upper guide tube and a lower guide tube, respectively, to receive segmented sleeves and provide space for wires to pass through. The glue guiding assembly includes a semi-circular glue guiding plate that passes through the lower guide tube and extends into the installation cavity to inject glue into the annular gap formed by the sleeve and the wire. An assembly unit is installed on the top of the base, with a drive mechanism on it. This mechanism leads out the end of the wire not bonded to the sleeve through a wire unit fixedly installed at the bottom of the top plate, winds it to the transformer, and finally completes the assembly of the sleeved wire.

[0006] This invention provides an automatic bushing device for small transformer leads. Compared with the prior art, it has the following advantages: 1. To address the issues of low efficiency and poor consistency caused by the dispersed and manual operation of various processes in the assembly of transformer lead-out bushings in existing technologies, this invention combines a base and workbench with a loading unit, a pushing unit, a fitting unit, a wire unit, an assembly unit, a clamping assembly, a conveying assembly, and a guide belt assembly to form a complete work process. This integrates the originally dispersed processes of threading, bushing, dispensing, curing, assembly, and wrapping into an automated production line, replacing cumbersome manual operations, improving production efficiency, and ensuring high product consistency.

[0007] 2. To address issues such as sleeve deformation, difficulty in aligning the wire and sleeve, uneven glue filling, and slow curing during sleeve assembly, this invention first uses a heating component in the pushing unit to uniformly soften the sleeve. A liftable air needle is then used to precisely inflate the sleeve, causing deformed areas to expand and return to their original position. In the bonding stage, a semi-circular glue guide plate is used, and UV glue is evenly injected into the annular gap between the sleeve and the wire through a top nozzle, achieving instantaneous irradiation curing of the glue and shortening the process cycle. In the assembly stage, the inclined mating surface cooperates with the insertion interface of the assembly mold head to smoothly release the bonded wire and sleeve assembly, improving efficiency.

[0008] 3. This invention proposes a clamping assembly that, through a longitudinal electric slide rail, a lifting clamping plate, a horizontal electric slide rail, and a clamping telescopic cylinder, enables the transformer clamps to stably clamp and accurately position small transformers of different sizes and shapes. Then, the loading screw drives the carrier plate to move, flexibly adjusting the position of the wire coil and hose coil. This facilitates the replacement of consumables and allows for fine-tuning of the output tension to cope with changes in the diameter of the consumable coil. Thus, this invention is compatible with bushings and wires of different diameters and automatically resets after assembly, enhancing the versatility of the equipment. Attached Figure Description

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] As an embodiment of the present invention, in order to solve the technical problems in the background art, such as Figures 1-4 As shown, a small transformer lead wire automatic bushing device is given below, including: base 100, assembly unit 200, pushing unit 300, loading unit 400, guide belt assembly 500, conveying assembly 600, fitting unit 700, conductor unit and clamping assembly 900.

[0014] In this embodiment, a workbench 101 is fixed on the top of the base 100. An operating cavity 102 is provided at the front of the workbench 101, which contains a clamping assembly 900 for clamping and moving the transformer to be processed. A guide belt assembly 500 (for winding tape) and an assembly unit 200 (for winding and cutting wires) are respectively installed on both sides of the workbench 101.

[0015] Furthermore, a loading unit 400 is jointly mounted on the top of the base 100 and the workbench 101. This unit contains a loading assembly 410 and a guiding assembly 420 for storing and guiding bushings and wires. The guiding assembly 420 is fixedly installed on top of the loading assembly 410. A movable pushing unit 300 is mounted at the bottom of the loading unit 400, responsible for transporting the heated bushings in segments to the front. A wire unit 800 is fixed on the loading unit 400 in front of the pushing unit 300 for pulling and guiding the wires. A fitting unit 700 is integrated within the loading unit 400 below the pushing unit 300 and the wire unit 800. This unit sequentially completes the bushing inflation correction, segmentation, adhesive bonding, and fitting with the wires, finally cooperating with the assembly unit 200 to assemble the bushing-equipped wires onto the transformer. A conveying assembly 600 is also provided on the front of the workbench 101 for automatically conveying the transformers to be processed.

[0016] In this embodiment, as Figure 1 , Figure 11 As shown, the proposed assembly unit 200 includes: an X-axis lead screw guide rail 201, a Y-axis lead screw guide rail 202, a lifting support plate 203, a lifting drive block 204, a rotating arm 205, a lead wire clamp 206, a die head insertion block 207, and a lead wire shearing blade 208. The X-axis lead screw guide 201 is fixed to one side of the top of the worktable 101, and a linearly movable Y-axis lead screw guide 202 is mounted on it. A linearly movable lifting support plate 203 is mounted on the top of the Y-axis lead screw guide 202. A lifting drive block 204 is mounted on the top of the lifting support plate 203. A rotating arm 205 is rotatably mounted on the lifting drive block 204. A lead wire clamp 206 is fixedly mounted on one side of the rotating arm 205 for clamping the end of the lead wire drawn from the lead wire unit 800 and processed by the assembly unit 700, and winding it onto the transformer held by the assembly unit 200 through the linkage of the X-axis, Y-axis and lifting drive block 204. A die head plug block 207 is rotatably mounted at the bottom and a lead wire cutter 208 is telescopically mounted at the top for cutting the lead wire after winding.

[0017] In specific implementation, such as Figure 11 As shown, a drive mechanism is formed by the X-axis and Y-axis lead screws and guides. This drive mechanism, through horizontal and vertical transmission and in conjunction with the lifting drive block 204, achieves precise positioning of the rotating arm 205 in three-dimensional space. The rotation of the rotating arm 205 itself further expands the working range, adapting to the assembly needs of small transformers of different specifications. The lead wire shearing blade 208 cuts the wire after winding, as shown... Figures 8-9 As shown, the mold head plug block 207 rotates and inserts into the plug interface 737 of the set mold head 732 during the set assembly process. By using its inclined mating surface, the elastically connected set mold head 732 is opened, thereby assisting in the completion of the pulling out of the wire and the bushing and the final assembly of the transformer.

[0018] In this embodiment, as Figures 2-3 , Figures 5-6 As shown, the pushing unit 300 includes: a mounting bracket 301, a guide pipe 302, a connector 303, a heating assembly 310, a guiding assembly 320, and a moving assembly 330. Among them, Mounting bracket 301 is fixedly installed at the bottom of moving component 330. Conveying component 320 is fixedly installed on one side and conveying pipe 302 is fixedly installed on the other side. A connector 303 is fixedly connected to the bottom end of conveying pipe 302, and a heating component 310 is actively rotated and installed inside it.

[0019] Furthermore, the moving component 330 includes a push telescopic cylinder 331, a vertical electric slide rail 332, and a guide seat 333. The vertical electric slide rail 332 is fixed to the bottom of the top plate 421 of the loading unit 400, and the guide seat 333 is slidably mounted on the vertical electric slide rail 332. Its bottom is connected to the top of the mounting frame 301 through two sets of push telescopic cylinders 331, thereby driving the mounting frame 301 to move flexibly in the horizontal and vertical directions to accurately adjust the position of the guide tube 302 and the connector 303, ensuring that the sleeve is accurately introduced into the set unit 700.

[0020] Furthermore, the heating assembly 310 includes a guide block 311, a fan 312, and a heating plate 313. The guide block 311 is flipped inside the mounting frame 301 to facilitate the insertion and maintenance of the sleeve. A through guide hole is provided between the mounting frame 301 and the guide block 311 to ensure a smooth sleeve transport path. A heating chamber 314 is provided inside the guide block 311, and the heating plate 313 is installed inside the heating chamber 314. The fan 312 is installed outside the guide block 311, and the output end of the fan 312 is connected to the heating chamber 314. The purpose is to generate heat through the heating plate 313 and evenly introduce hot air into the heating chamber 314 by the fan 312, thereby achieving uniform heating of the passing sleeve and preparing it for subsequent air blowing correction.

[0021] Furthermore, such as Figure 6 As shown, the conveying assembly 320 includes a mounting cover 321, a driven roller 322, a driving roller 323, and a gear set 324. The mounting cover 321 is fixed to one side of the conveying block 311, and the driving roller 323 and driven roller 322, synchronously driven by the gear set 324, are rotatably mounted inside it. It can be understood that the driving roller 323 and driven roller 322, synchronously driven by the gear set 324, convey the sleeve in opposite directions, preventing slippage and ensuring stable conveying speed. The mounting cover 321 forms a closed conveying space, protecting the sleeve from external interference and improving conveying stability.

[0022] Based on the above technical concept, it should be noted that the operating principle of the pushing unit 300 is as follows: The moving component 330 first drives the mounting frame 301 to move above the hose roll 417. The sleeve is clamped and introduced by the active roller 323 and driven roller 322 of the guiding component 320. After being heated and softened by the heating chamber 314 of the heating component 310, it is guided by the guiding pipe 302 and finally output by the docking joint 303. Under the precise positioning of the moving component 330, it is docked with the cutting component 750 of the packaging unit 700 to complete the preparation and supply of the sleeve and send the sleeve into the subsequent processing steps.

[0023] In this embodiment, as Figure 5 , Figure 7As shown, the kit unit 700 includes: a push-pull assembly 710, an air blowing component 720, a kit assembly 730, an adhesive guiding assembly 740, and a slitting assembly 750.

[0024] In specific implementation, such as Figure 7 As shown, the push-pull assembly 710 includes a push-pull telescopic cylinder 711, a push-pull connecting frame 712, and a mounting plate 713. The mounting plate 713 is fixedly installed on the inner side of the guide support plate 425 of the loading unit 400. The push-pull telescopic cylinder 711 is fixedly installed on one side of the mounting plate 713. The output end of the push-pull telescopic cylinder 711 passes through the mounting plate 713 and is connected to the push-pull connecting frame 712. It is used to drive the push-pull connecting frame 712 to move back and forth to accurately adjust the position of the sleeve mold head 732 and ensure that the sleeve and the wire are accurately connected and sleeved.

[0025] Furthermore, such as Figure 7 As shown, the assembly 730 is fixedly installed on the front side of the push-pull connecting frame 712. The assembly 730 includes an assembly connecting frame 731 and an assembly mold head 732. The assembly connecting frame 731 is fixedly installed on the front side of the push-pull connecting frame 712, as shown... Figure 8 As shown, two sets of spring rods 738 are installed inside the kit connecting frame 731. The kit connecting frame 731 is connected to the kit mold head 732 via the spring rods 738. The kit mold head 732 has an insertion interface 737 on its front side, and an installation cavity 736 is provided inside the insertion interface 737. Figure 9 As shown, the top of the mold head 732 is fitted with an upper guide tube 733 extending into the mounting cavity 736, and the bottom of the mold head 732 is fitted with a lower guide tube 735 extending into the mounting cavity 736. A UV curing unit 734 is fixedly installed in the mounting cavity 736 between the lower guide tube 735 and the upper guide tube 733.

[0026] Based on the above technical concept, it can be understood that the insertion interface 737 and mounting cavity 736 of the kit head 732 provide limiting space for the sleeve, preventing sleeve misalignment and improving connection stability. The upper guide tube 733 and lower guide tube 735 provide guiding channels for the UV adhesive, and together with the adhesive guiding component 740, can evenly deliver the adhesive to the gap between the sleeve and the wire, ensuring a firm bond. The UV curing unit 734 in the mounting cavity 736 can quickly irradiate and cure the UV adhesive, shortening the curing time and improving work efficiency. The kit head 732 is connected to the kit connecting frame 731 via a spring rod 738, giving it a certain degree of elastic adjustment capability to adapt to sleeves and wires of different diameters, improving equipment compatibility. The elastic reset function of the spring rod 738 facilitates the reset of the kit head 732 after the wire is pulled out, ensuring subsequent operations.

[0027] Furthermore, such as Figures 7-9As shown, the air blowing component 720 includes an air blowing telescopic cylinder 721 and an air blowing needle 723. The air blowing telescopic cylinder 721 is fixedly installed at the bottom of the push-pull connecting frame 712, and its output end extends downward from the cylinder body, with a connecting plate 722 connected to the end. The air blowing needle 723 is vertically fixedly installed on the connecting plate 722, and the bottom end of the air blowing needle 723 penetrates downward through the push-pull connecting frame 712. An air inlet 725 is fixedly installed at the bottom of the push-pull connecting frame 712 for connecting to an external air source. Understandably, during operation, the air-blowing telescopic cylinder 721 drives the connecting plate 722 and the air-blowing needle 723 to move upward, allowing the top of the air-blowing needle 723 to pass through the push-pull connecting frame 712 and be precisely inserted into the sleeve inside the upper cutting component 750. After the air inlet 725 is connected to the external blower, the airflow is evenly injected into the heated sleeve through the air-blowing needle 723, causing the flattened and deformed parts of the sleeve to expand and reset, restoring its regular shape, ensuring compatibility with the wire, and improving the assembly qualification rate.

[0028] Furthermore, such as Figure 8 , Figure 10 As shown, the adhesive guiding assembly 740 includes a connecting plate 741, an adhesive guiding seat 742, an adhesive guiding tube 743, an adhesive receiving nozzle 744, a semi-circular adhesive guiding plate 745, and an adhesive dispensing nozzle 746. Figure 9 As shown, its overall structure is fixedly installed on the air pipe 724 below the push-pull connecting frame 712 via the connecting plate 741. One end of the connecting plate 741 is fixedly connected to the glue guide seat 742. The top of the glue guide seat 742 is fixedly connected to the glue inlet 744. The side of the glue inlet 744 is connected to two sets of glue guide tubes 743. The end of each set of glue guide tubes 743 is fixedly connected to a semi-circular glue guide plate 745. Multiple glue outlets 746 are distributed on the top of the semi-circular glue guide plate 745.

[0029] Based on the above technical concept, it can be understood that the adhesive guiding component 740 is connected to an external adhesive source through the adhesive receiving nozzle 744. The adhesive is guided to the semi-circular adhesive guiding plate 745 through the adhesive guiding tube 743 and finally extruded from the adhesive dispensing nozzle 746. During operation, the adhesive receiving nozzle 744, adhesive guiding tube 743 and semi-circular adhesive guiding plate 745 of the adhesive guiding component 740 form a precise adhesive guiding path. The semi-circular adhesive guiding plate 745 can pass through the lower guide tube 735 of the die head 732 and extend into the installation cavity 736. Its semi-circular structure can avoid the wire, thereby accurately injecting the adhesive into the annular gap between the sleeve and the wire.

[0030] Furthermore, such as Figure 7 As shown, the slitting assembly 750 includes a sleeve guide 751, an upper connecting pipe 752, a lower connecting pipe 753, and a slitting blade 754. Wherein, as... Figure 16 As shown, the sleeve guide seat 751 is fixedly installed inside the guide support plate 425 above the push-pull connecting bracket 712, and its upper end is connected to the upper connecting pipe 752, as shown. Figure 6As shown, the upper connecting pipe 752 is precisely connected to the connecting pipe 303 of the pushing unit 300 to receive the sleeve conveyed from the guide pipe 302. The bottom of the sleeve guide seat 751 is connected to the lower connecting pipe 753. It can be understood that the lower connecting pipe 753 corresponds to and connects with the upper guide pipe 733 of the assembly mold head 732 in the assembly assembly 730 to form a continuous conveying channel. The slitting blade 754 is mounted on one side of the sleeve guide seat 751. Its blade can extend and retract into the internal channel of the sleeve guide seat 751, which can realize the precise segmentation of the sleeve, control the consistent length of the sleeve, and improve the assembly accuracy.

[0031] Based on the above technical concept, it can be understood that during operation, the continuous sleeve, after being heated and corrected by the pushing unit 300, enters the slitting assembly 750 through the connector 303 and the upper connector 752. The slitting blade 754 operates under drive to cut the passing sleeve to a fixed length. The segmented sleeve is then pushed by the subsequent sleeve and accurately guided into the mounting cavity 736 of the set die head 732 through the lower connector 753 and the upper guide tube 733, waiting to be sleeved and assembled with the wire.

[0032] In this embodiment, as Figure 2 , Figure 5 As shown, the loading assembly 410 includes: a support frame 411, a guide block 412, a loading screw 413, a roll guide kit 414, a wire roll 415, a support plate 416, and a hose roll 417.

[0033] In practice, the support frame 411 serves as the main frame and is fixedly installed on the top side of the base 100. The loading screw 413 is rotatably installed inside the support frame 411. The guide block 412 is threaded onto the loading screw 413 and moves linearly under the guidance of the support frame 411.

[0034] Furthermore, there are two support plates 416, each of which is fixedly installed on both sides of the guide block 412. The wire roll 415 and the hose roll 417, as consumables, are placed on the support plates 416 on both sides. On both sides of the support frame 411 and above the wire roll 415 and the hose roll 417, a roll material guide kit 414 for initial guidance is fixedly installed. The loading screw 413 drives the guide block 412 to move. The position of the support plate 416 can be adjusted according to the remaining amount of consumables, which facilitates consumable replenishment and tension adjustment.

[0035] In this embodiment, as Figure 2 , Figure 5 As shown, the guide assembly 420 includes: a top plate 421, a transverse guide rod 422, a wire guide kit 423, a guide sleeve 424, and a guide support plate 425.

[0036] In specific implementation, the top plate 421 is fixedly installed on the top of the support frame 411 of the loading assembly 410, and the transverse guide rod 422 is fixedly installed on the top plate 421. Multiple wire guide kits 423 for guidance are distributed and installed on its top. A guide sleeve 424 is fixedly installed on the top plate 421 and communicates with the mounting cylinder 801 of the wire unit 800, thereby ensuring the smooth introduction of the wire into subsequent components and improving the accuracy of conveying and assembly. Figure 7 As shown, the guide support plate 425 is vertically fixedly installed at the bottom of the top plate 421, and its lower end is fixedly connected to the top of the workbench 101. The guide support plate 425 and the top plate 421 form a rigid support structure, providing a stable installation foundation for the upper guide assembly 420 and the lower push unit 300 and assembly unit 700, and avoiding the influence of structural shaking on the guidance and assembly accuracy during operation.

[0037] Based on the above technical concept, it should be noted that, based on the loading unit 400, the feeding and guiding principle proposed in this invention is as follows: During operation, firstly, the operator places the wire roll 415 and the hose roll 417 on the bearing plates 416 on both sides of the loading assembly 410 respectively. By driving the loading screw 413 to rotate, the guide block 412 and the bearing plate 416 can be moved synchronously and linearly, thereby realizing a dual adjustment function: firstly, the bearing position can be flexibly adjusted according to the remaining amount of consumables, which is convenient for quick replenishment and replacement; secondly, the tension when the consumables are discharged can be finely adjusted to provide a stable supply for subsequent processes.

[0038] Subsequently, the conductor is led out from the wire reel 415, passing sequentially through the upper reel guide assembly 414 and the conductor guide assembly 423 on the transverse guide rod 422, finally converging into the guide sleeve 424. At this point, the aforementioned components together form a continuous guide channel. Ultimately, the conductor is smoothly and accurately guided into the subsequent conductor unit 800 through the guide sleeve 424. This completes the process from material storage, tension adjustment, path guidance to conveying connection.

[0039] In this embodiment, as Figure 1 , Figure 12 As shown, the guide belt assembly 500 includes: a Z-axis lead screw guide rail 501, a placement frame 502, a side plate 503, a guide wheel 504, a belt clamp 505, a roller 506, and a belt telescopic cylinder 507.

[0040] In practice, the Z-axis lead screw guide 501 is vertically fixed to one side of the top of the workbench 101. The placement frame 502 is mounted on the Z-axis lead screw guide 501 and is driven to move linearly in the vertical direction. The side plate 503 is vertically fixed to the side of the placement frame 502. The guide wheel 504 and roller 506 are rotatably mounted inside the side plate 503, with the roller 506 mounted at the end of the guide wheel 504. The tape telescopic cylinder 507 is fixedly mounted on one side of the side plate 503, with its output end extending forward and docking with the tape gripper 505. This drives the tape gripper 505 to clamp and pull the tape to the top surface of the roller 506, so as to cooperate with the assembly unit 200 to complete the automatic tape winding of the transformer. This achieves precise clamping of the tape end and the cutting point, preventing the tape from falling off or shifting. It also reduces tape waste and ensures the continuity of operation in conjunction with subsequent cutting actions.

[0041] Based on the above technical concept, it should be noted that during operation, the Z-axis lead screw guide 501 first drives the placement frame 502 and the entire side mechanism to move, positioning the roller 506 at a suitable position below the transformer. The tape gripper 505 extends forward under the push of the tape telescopic cylinder 507, clamping the end of the tape leading out from the placement frame 502 and pulling it to the top surface of the roller 506. When the clamping assembly 900 presses down the transformer and contacts the tape on the top surface of the roller 506, the tape is continuously pulled out under the action of friction by driving the transformer to rotate. At this time, the guide wheel 504 and the roller 506 together constitute the tape guiding and support system, ensuring smooth conveying and controlling the winding tension by adjusting the fit, ultimately achieving tight and uniform winding of the tape on the transformer.

[0042] In this embodiment, as Figures 1-3 As shown, the conveying assembly 600 includes a conveying frame 601, a conveying electric slide rail 602, and a placement seat 603. The conveying frame 601 is mounted on a base 100 on the front side of the workbench 101. The conveying electric slide rail 602 is fixedly installed on the top of the conveying frame 601, and the placement seat 603 is slidably mounted on the conveying electric slide rail 602, and its interior is provided with a cavity or slot for placing the small transformer to be processed.

[0043] Based on the above technical concept, it should be noted that the conveying component 600 is used to automatically transfer the transformer before and after the processing steps. During operation, the conveying slide rail 602 drives the placement seat 603 to move in a straight line, accurately conveying it to the working area of ​​the clamping component 900 in front of the operating chamber 102. After the clamping component 900 completes the picking up of the part, the unloaded placement seat 603 returns to the starting position to wait for loading. When the transformer completes all processing (winding, sleeve installation, and tape winding), the clamping component 900 puts the finished product back into the placement seat 603, and the conveying slide rail 602 then transports it to the designated unloading position. It can be understood that the automated conveying process proposed by the conveying component 600 replaces manual handling, ensuring the continuity of process connections and positioning accuracy, thereby improving the overall operation efficiency.

[0044] In this embodiment, as Figure 2 , Figure 5 , Figure 14 As shown, the conductor unit 800 includes: an installation cylinder 801, a conductor clamping telescopic cylinder 802, an upper sliding block 803, a lower sliding block 804, a guide block 805, a conductor cylinder 806, a conductor lifting telescopic cylinder 807, and a wire outlet 808.

[0045] In specific implementation, the mounting cylinder 801 is fixedly installed at the bottom of the top plate 421 of the guide assembly 420, and its inlet is connected to the guide sleeve 424. There are two wire clamping telescopic cylinders 802. The two wire clamping telescopic cylinders 802 are fixedly installed side by side at the top inside the mounting cylinder 801, and the output end of each wire clamping telescopic cylinder 802 faces downward and is connected to an upper sliding block 803.

[0046] Furthermore, a lower sliding block 804 is slidably mounted below each upper sliding block 803. Two sets of guide blocks 805 are also provided, fixedly installed on the inner wall of the mounting cylinder 801 and located below the lower sliding block 804. The wire clamping telescopic cylinder 802 pushes the lower sliding block 804 against the guide block 805 via the upper sliding block 803, stably clamping and pulling the wire to prevent slippage and deviation, ensuring accurate wire delivery length. Simultaneously, the guide block 805 provides a regular path for the wire, reducing delivery resistance; the wire cylinder 801... The six sleeves are mounted on the bottom of the mounting cylinder 801 and can slide relative to each other. The wire lifting telescopic cylinder 807 is fixed inside the bottom of the mounting cylinder 801, and its output end is connected to the wire cylinder 806 to drive its lifting and lowering. The height of the wire outlet 808 can be adjusted to adapt to different working position requirements. The wire outlet 808 is fixedly installed at the bottom outlet of the wire cylinder 806. At this time, the wire cylinder 806 and the wire outlet 808 form a precise guiding channel to ensure that the wire and the sleeve are transported synchronously and accurately connected, avoiding assembly deviations caused by the wire being too long or too short, and improving the sleeve installation accuracy.

[0047] Based on the above technical concept, it should be noted that the conductor unit 800 serves as a conductor conveying and length control mechanism. During operation, such as... Figure 5 As shown, after the wire enters the mounting cylinder 801 from the guide sleeve 424, it passes through the channel formed by the guide block 805. When it is necessary to pull or stop the wire, the wire clamping telescopic cylinder 802 is activated, pushing the upper sliding block 803, which in turn forces the lower sliding block 804 to generate misalignment friction with the fixed guide block 805, thereby reliably clamping or releasing the wire. The wire lifting telescopic cylinder 807 drives the entire wire cylinder 806 and the outlet nozzle 808 to rise and fall, which can flexibly adjust the outlet height to adapt to the needs of different work positions. Thus, through the coordination of clamping, releasing and lifting actions, the proposed wire unit 800 can control the lead-out length of the wire and accurately guide the wire into the fitting mold head 732 of the lower fitting unit 700, providing precise length and position for the fitting and assembly of the wire and the sleeve.

[0048] In this embodiment, as Figure 2 , Figure 13 As shown, the clamping assembly 900 includes: a lifting clamping plate 901, a horizontal electric slide rail 902, a clamping telescopic cylinder 903, a transformer gripper 904, and a longitudinal electric slide rail 905.

[0049] In specific implementation, the longitudinal electric slide rail 905 is slidably mounted on the bottom of the operating cavity 102, and the lifting clamping plate 901 is installed on the top of the longitudinal electric slide rail 905, which drives it to move longitudinally or back and forth. The horizontal electric slide rail 902 is fixedly installed on the front of the lifting clamping plate 901, and the clamping telescopic cylinder 903 is slidably mounted on the horizontal electric slide rail 902 and can move laterally along it. In actual application, the clamping telescopic cylinder 903 achieves its own rotation through an active rotary cylinder. Through the cooperation of the two, the clamping angle and force of the transformer jaw 904 can be adjusted to adapt to transformers of different sizes and shapes, and improve clamping stability. The transformer jaw 904 is fixedly installed on the output end of the clamping telescopic cylinder 903 and is used to clamp the small transformer to be processed.

[0050] Based on the above technical concept, it should be noted that the clamping assembly 900 is used for positioning and transporting the transformer. During operation, the transformer grippers 904 achieve precise movement in four degrees of freedom—forward / backward, up / down, left / right, and rotation—through the longitudinal electric slide rail 905, the lifting clamping plate 901 itself, the horizontal electric slide rail 902, and the active rotary cylinder. The transformer grippers 904 directly clamp the small transformer to be processed. During operation, such as... Figure 1As shown, the transformer is first moved to the placement seat 603 of the conveying component 600 to pick up the material. Then, the transformer is precisely transported and positioned to multiple workstations such as winding, sleeve fitting, and tape winding. During this process, the adjustable degree of freedom of the transformer gripper 904 can not only adapt to transformers of different sizes and shapes to ensure stable clamping, but also cooperate with the assembly unit 200 and the guide belt assembly 500 to complete complex winding and assembly actions, achieving high-precision operation.

[0051] In this embodiment, the working principle and usage process of the present invention are as follows: S1. Feeding and threading: (e.g.) Figure 5 As shown, hose reel 417 and wire reel 415 are respectively placed on the support plate 416 of the loading assembly 410. The wire and sleeve are supplied in parallel. The wire enters the mounting cylinder 801 through the reel guide kit 414, the wire guide kit 423 and the guide sleeve 424. Figure 14 As shown, the wire clamping telescopic cylinder 802 drives the sliding block 804 to clamp and pull the wire, so that it passes through the wire cylinder 806 and the outlet nozzle 808; at the same time, the pushing unit 300 moves above the hose roll 417, and the driving roller 323 and driven roller 322 of the guiding assembly 320 guide the sleeve in, and preheat it through the heating chamber 314 of the heating assembly 310.

[0052] S2, Sleeve Correction: (e.g., ...) Figure 2 , Figure 16 As shown, the preheated sleeve enters the slitting assembly 750 via the guide pipe 302 and the connector 303. Figure 7 , Figure 9 As shown, the air blowing telescopic cylinder 721 of the air blowing component 720 drives the air blowing needle 723 to rise and insert into the sleeve. An external air source inflates the sleeve through the air pipe 724 and the air inlet 725. With the continuous heating of the heating component 310, the deformed part of the sleeve expands and returns to its original position, thus correcting the problem.

[0053] S3. Sleeve Segmentation and Conveying: The slitting blade 754 of the slitting assembly 750 cuts the corrected sleeve into segments. The segmented sleeves are guided through the lower connecting pipe 753 into the upper guide pipe 733 of the mounting assembly 730 and then into the mounting cavity 736. Figure 9 As shown, the push-pull telescopic cylinder 711 of the push-pull assembly 710 pushes the suit mold head 732 forward to below the outlet nozzle 808, and the wire unit 800 pulls the wire again, so that it passes through the upper guide tube 733 and through the sleeve, completing the physical connection between the wire and the sleeve.

[0054] S4, Transformer windings: such as Figure 2 , Figure 13As shown, the transformer gripper 904 of the clamping assembly 900 clamps the transformer from the placement seat 603 of the conveying assembly 600. After clamping the small transformer to be processed, it returns to the work station. At this time, the lead wire gripper 206 of the assembly unit 200 clamps the end of the wire that has not yet been bonded to the bushing and is led out from the set mold head 732. It pulls the wire to the transformer pin for initial winding.

[0055] S5. Sleeve dispensing and curing: (e.g.) Figure 10 As shown, the semi-circular adhesive guide plate 745 of the adhesive guide assembly 740 rises and inserts into the sleeve. An external adhesive source injects UV adhesive into the gap between the sleeve and the wire through the adhesive inlet 744, the adhesive guide tube 743 and the adhesive outlet 746. Subsequently, the ultraviolet irradiator 734 in the mounting cavity 736 of the die head 732 is activated, which makes the adhesive cure quickly, thereby firmly bonding the sleeve to the wire in the middle section to form a wire and sleeve assembly.

[0056] S6. Sleeve assembly and wrapping: (e.g.) Figure 4 As shown, the lead wire clamp 206 of the assembly unit 200 clamps the wire portion connected to the wire coil on the wire sleeve assembly. The die head plug block 207 is inserted into the plug interface 737 of the set die head 732 to open it. After the lead wire cutter 208 cuts the wire, the lead wire clamp 206 pulls the solidified wire sleeve assembly out of the set die head and finally assembles it into the transformer. Finally, the guide tape assembly 500 completes the automatic tape winding, and the processed transformer is sent out to the unloading position by the conveyor assembly 600.
