[0035] In the description of the present invention, if the first and second are described only for the purpose of distinguishing technical features, they cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence of the indicated technical features.

[0036] In the description of the present invention, unless otherwise clearly defined, words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0037] The semi-finished product of the transformer includes a bobbin and windings wound around the bobbin. The bobbin is in the shape of a Chinese character 'Ri'. The terminals connected to the windings are fixed on the end faces of the bobbin. The straight line where the main body of the terminal is located is the axial direction of the terminal. The axial direction of the terminal is perpendicular to the end face of the bobbin. It is necessary to wind copper skin layers on the four side faces of the bobbin, and connect the copper skin layers and a terminal through flying wires. This one terminal is also called the fixed terminal, that is, the two ends of the flying wire are respectively connected to the copper skin layer and the fixed terminal. Finally, wrap the copper skin layer with tape, and the tape covers the solder joints between the copper skin layer and the flying wire.

[0038] Refer to Figure 1 and Figure 2 According to the present invention, a transformer flying wire welding device is disclosed, including: a frame 100, a copper skin wrapping device 200 and a flying wire welding device 300. A first transfer device 110 is provided on the frame 100, and the copper skin wrapping device 200 is used to wrap a copper skin layer on the bobbin of the semi-finished product.

[0039] Refer to Figures 3 to 7 According to, the flying wire welding device 300 includes a welding mechanism 310, a driving mechanism 320, a wire feeding mechanism 330 and a semi-finished product clamp 340. The first transfer device 110 is used to transfer the semi-finished product wrapped with a copper skin layer to the semi-finished product clamp 340. The wire feeding mechanism 330 is arranged behind the semi-finished product clamp 340. The wire feeding mechanism 330 includes a wire outlet pipe 334 extending in the front-rear direction. The wire outlet pipe 334 is used to send out wires. The driving mechanism 320 is arranged on the frame 100. The driving mechanism 320 is used to drive the wire outlet pipe 334 to move in the front-rear, left-right and up-down directions, so that the front end of the wire is placed on the copper skin layer of the semi-finished product on the semi-finished product clamp 340, and the wire of the semi-finished product on the semi-finished product clamp 340 is wound around the fixed terminal. The welding mechanism 310 includes a welding head 311, a first pressing head 312 and a second pressing head 313 that can all move up and down. The first pressing head 312 moves down to press the front end of the wire on the copper skin layer. The welding head 311 moves down to weld the end of the wire on the copper skin layer. The second pressing head 313 moves down to press the semi-finished product tightly on the semi-finished product clamp 340. The wire outlet pipe 334 drives the wire to move, so that the wire is wound around the fixed terminal and is broken, and a flying wire is welded on the semi-finished product.

[0040] When the transformer welding jumper wire device is working, the welding mechanism 310 is in the high position, and the wire feeding mechanism 330 is behind the semi-finished product fixture 340 to prevent the semi-finished product fixture 340 from being blocked. First, place the semi-finished product on the copper-cladding device 200, and the copper-cladding device 200 winds copper layers around the four sides of the skeleton of the semi-finished product; then the first transfer device 110 transports the semi-finished product coated with the copper layer to the semi-finished product fixture 340; then the driving mechanism 320 drives the wire outlet pipe 334 to move in the front-back, left-right, and up-down directions, that is, the wire outlet pipe 334 moves in space to approach the semi-finished product on the semi-finished product fixture 340, and makes the front end of the wire sent out by the wire outlet pipe 334 rest on the copper layer of the semi-finished product; immediately afterwards, the first pressing head 312 moves down to press the front end of the wire on the copper layer, the welding head 311 moves down to weld the end of the wire to the copper layer, and the second pressing head 313 moves down to press the semi-finished product tightly on the semi-finished product fixture 340; then the driving mechanism 320 drives the wire outlet pipe 334 to move in the front-back, left-right, and up-down directions again, and the wire sent out by the wire outlet pipe 334 is wound around the fixed terminal. Immediately afterwards, the wire outlet pipe 334 drives the wire to move in a direction perpendicular to the axial direction of the fixed terminal, so that the wire between the fixed terminal and the wire outlet pipe 334 is disconnected, completing the connection of the semi-finished product jumper wire, that is, completing the welding of the jumper wire; finally, the welding mechanism 310 moves up, and the wire feeding mechanism 330 moves backward to prevent the semi-finished product fixture 340 from being blocked, and then the semi-finished product with the welded jumper wire can be taken away.

[0041] It should be understood that when welding the jumper wire to the semi-finished product, the axis of the fixed terminal on the semi-finished product is parallel to the front-back direction. The wire outlet pipe 334 drives the wire to wind around the fixed terminal. At this time, the direction of the wire sent out by the wire outlet pipe 334 is perpendicular to the axial direction of the fixed terminal. The wire outlet pipe 334 moves in a direction perpendicular to the axial direction of the fixed terminal so that the wire in the wire outlet pipe 334 and the wire between the wire outlet pipe 334 and the fixed terminal form a right angle or an acute angle. Under the action of the fixed terminal and the side wall of the wire outlet pipe 334, the wire between the fixed terminal and the wire outlet pipe 334 will be broken, and the broken end of the wire output by the wire outlet pipe 334 is near the outlet of the wire outlet pipe 334, and this end becomes the new end of the wire.

[0042] Refer to Figure 1 and Figure 2 In some of the embodiments, the transformer welding jumper wire device further includes a second transfer device 120 and a rubber coating device 400 both arranged on the frame 100. The second transfer device 120 is used to transfer the semi-finished product with the welded jumper wire to the rubber coating device 400, and the rubber coating device 400 is used to coat the copper layer of the semi-finished product with a tape. The tape is coated on the copper layer and covers the solder joint between the jumper wire and the copper layer to finally obtain the required finished product.

[0043] It can be understood that the structures of the copper-clad device 200 and the rubber coating device 400 are the same or similar. The rubber coating device 400 is a common device or apparatus or mechanism, and redundant introduction will not be made here.

[0044] In another embodiment, the transformer welding jumper wire device further includes a spot welding device. The spot welding device is arranged between the welding jumper wire device 300 and the rubber coating device 400. The semi-finished product with the welded jumper wire is transferred to the spot welding device. The spot welding device welds the jumper wire to the fixed terminal, and then transfers the semi-finished product after welding the jumper wire to the fixed terminal to the rubber coating device 400. The rubber coating device 400 coats the copper skin layer of the semi-finished product with rubber.

[0045] Refer to Figure 3 and Figure 6 In some of these embodiments, the welding jumper wire device 300 further includes a first rotation driving mechanism 350 and a carrier plate 360. The first rotation driving mechanism 350 is arranged on the frame 100. The carrier plate 360 is rotatably arranged on the frame 100 around the vertical axis. The output end of the first rotation driving mechanism 350 is in transmission connection with the carrier plate 360. Semi-finished product clamps 340 are arranged at both ends of the carrier plate 360. A first loading / unloading station and a welding jumper wire station are arranged on the frame 100 in a front-back distribution. The first transfer device 110 and the second transfer device 120 are both arranged at the first loading / unloading station. The welding jumper wire device 300 is arranged at the welding jumper wire station.

[0046] The carrier plate 360 is horizontally arranged, and the middle area of the carrier plate 360 is connected to the frame 100 through a first bearing. When the transformer welding jumper wire device works, both ends of the carrier plate 360 respectively correspond to the first loading / unloading station and the welding jumper wire station, that is, semi-finished product clamps 340 are provided in the areas corresponding to the first loading / unloading station and the welding jumper wire station. At the welding jumper wire station, while the welding jumper wire device 300 welds the jumper wire to the semi-finished product on the semi-finished product clamp 340, at the first loading / unloading station, the second transfer device 120 takes away the semi-finished product with the welded jumper wire on the semi-finished product clamp 340, and then the first transfer device 110 feeds a semi-finished product to be welded with a jumper wire to this semi-finished product clamp 340, which can effectively improve the efficiency of welding the jumper wire.

[0047] Refer to Figure 2 In some of these embodiments, a first handling mechanism 130 and a first rotating mechanism 140 are arranged in the area between the copper-clad device 200 and the welding jumper wire device 300 on the frame 100. The first handling mechanism 130 is used to transfer the semi-finished product on the copper-clad device 200 to the first rotating mechanism 140.

[0048] It can be understood that when the copper-clad device 200 clads the semi-finished product with a copper layer, the four sides of the semi-finished product are all parallel to the vertical direction, the axial direction of the fixed terminal of the semi-finished product is parallel to the vertical direction, the fixed terminal of the semi-finished product is at the highest position of the semi-finished product, the end face of the semi-finished product with the fixed terminal faces upward. When the first rotating mechanism 140 and the first transfer device 110 carry the semi-finished product, they will not rotate the semi-finished product, that is, they will not change the posture of the semi-finished product, but only change the position of the semi-finished product. When welding the flying wire to the fixed terminal, the end face of the semi-finished product with the fixed terminal needs to face backward, the fixed terminal is parallel to the front-rear direction, and one side of the semi-finished product and the copper layer thereon face upward, so as to facilitate the wire outlet pipe 334 to place the front end of the wire on the copper layer of the semi-finished product, that is, the front end of the wire is placed on the upward-facing copper layer area.

[0049] The first rotating mechanism 140 is used to drive the semi-finished product to rotate 90° with the front-rear direction as the rotation axis, so that the end face of the semi-finished product with the fixed terminal faces right or left. The first transfer device 110 transfers the semi-finished product on the first rotating mechanism 140 to the semi-finished product fixture 340 at the first loading and unloading station.

[0050] Then the carrier plate 360 rotates 180° with the vertical direction as the rotation axis, and the semi-finished product fixture 340 at the first loading and unloading station is transferred to the welding flying wire station. At this time, the end face of the semi-finished product at the welding flying wire station with the fixed terminal faces left or right. It is necessary to rotate the semi-finished product 90° with the vertical direction as the rotation axis, that is, the semi-finished product fixture 340 at the welding flying wire station needs to rotate 90° with the vertical direction as the rotation axis, so that the end face of the semi-finished product with the fixed terminal faces backward.

[0051] Refer to Figure 6 , in some of these embodiments, the welding flying wire device 300 further includes a first lifting drive mechanism 370. The first lifting drive mechanism 370 is provided in the area of the frame 100 corresponding to the welding flying wire station. The output end of the first lifting drive mechanism 370 is connected to a second rotation drive mechanism 371. A chuck is provided at the output end of the second rotation drive mechanism 371. The semi-finished product fixture 340 is rotatably provided on the carrier plate 360 with the vertical direction as the rotation axis. A card slot is provided at the lower end of the semi-finished product fixture 340. The first lifting drive mechanism 370 drives the second rotation drive mechanism 371 to rise, so that the chuck is inserted into the card slot. The second rotation drive mechanism 371 drives the semi-finished product fixture 340 to rotate 90° with the vertical direction as the rotation axis, so that the fixed terminal on the semi-finished product is close to the wire feeding mechanism 330.

[0052] It can be understood that the carrier plate 360 is provided with mounting holes penetrating the upper and lower surfaces of the carrier plate 360. A second bearing is provided in the mounting holes, and the semi-finished product fixture 340 is connected to the carrier plate 360 through the second bearing, so that the semi-finished product fixture 340 can rotate on its own axis on the carrier plate 360. The lower end of the semi-finished product fixture 340 extends below the carrier plate 360, and the card slot is provided below the carrier plate 360 and at the rotation axis of the semi-finished product fixture 340.

[0053] Initially, the first lifting drive mechanism 370 drives the second rotation drive mechanism 371 and the chuck to descend, and the chuck is in the low position. When the carrier plate 360 rotates 180° with the vertical direction as the rotation axis, the semi-finished product fixture 340 at the first loading and unloading station is transferred to the welding flying wire station. After that, the semi-finished product fixture 340 at the welding flying wire station is directly opposite to the chuck. The first lifting drive mechanism 370 drives the second rotation drive mechanism 371 and the chuck to ascend, so that the chuck is inserted into the card slot. Then, the second rotation drive mechanism 371 drives the semi-finished product fixture 340 to rotate 90° with the vertical direction as the rotation axis through the cooperating chuck and card slot. The semi-finished product fixture 340 drives the semi-finished product to rotate 90° with the vertical direction as the rotation axis, so that the axis of the fixed terminal is parallel to the front-back direction, that is, the end face of the semi-finished product provided with the fixed terminal faces backward, and the fixed terminal on the semi-finished product is close to the wire feeding mechanism 330. Then the welding flying wire device 300 can perform welding flying wire on the semi-finished product.

[0054] After the semi-finished product completes the welding flying wire, the second rotation drive mechanism 371 drives the semi-finished product fixture 340 to rotate 90° in the reverse direction with the vertical direction as the rotation axis through the cooperating chuck and card slot. The first lifting drive mechanism 370 drives the second rotation drive mechanism 371 and the chuck to descend, so that the chuck and the card slot are disengaged. The carrier plate 360 rotates 180° again with the vertical direction as the rotation axis, so that the semi-finished product that has completed the welding flying wire returns to the first loading and unloading station, and the posture of the semi-finished product that has completed the welding flying wire when it returns to the first loading and unloading station is the same as the posture when the semi-finished product was initially transported to the first loading and unloading station, while the semi-finished product to be welded with flying wire at the first loading and unloading station is transferred to the welding flying wire station.

[0055] Refer to Figure 2 In some of the embodiments, a second handling mechanism 150 and a second rotating mechanism 160 are provided in the area between the welding flying wire device 300 and the encapsulation device 400 on the frame 100. The second handling mechanism 150 is used to transport the semi-finished product on the semi-finished product fixture 340 to the second rotating mechanism 160.

[0056] It can be understood that when the tape wrapping device 400 wraps the semi-finished product with tape, all four sides of the semi-finished product need to be kept parallel to the vertical direction, the axial direction of the fixed terminal of the semi-finished product is parallel to the vertical direction, the fixed terminal is at the highest position of the semi-finished product, and when the second handling mechanism 150 and the second transfer device 120 handle the semi-finished product, they will not rotate the semi-finished product, that is, they will not change the posture of the semi-finished product, but only change the position of the semi-finished product. When the copper tape wrapping device 200 wraps the semi-finished product with tape, it is necessary to make the posture of the semi-finished product the same as the posture on the tape wrapping device 400, all four sides of the semi-finished product are parallel to the vertical direction, the axial direction of the fixed terminal of the semi-finished product is parallel to the vertical direction, the end face of the semi-finished product provided with the fixed terminal faces upward, and the fixed terminal of the semi-finished product is at the highest position of the semi-finished product.

[0057] The second rotating mechanism 160 is used to drive the semi-finished product to rotate 90° with the front-back direction as the rotation axis. The rotation direction of the semi-finished product driven by the second rotating mechanism 160 is opposite to the rotation direction of the semi-finished product driven by the first rotating mechanism 140, so that the posture of the semi-finished product at this time is the same as the posture when it is on the copper tape wrapping device 200. The second transfer device 120 is used to transfer the semi-finished product on the second rotating mechanism 160 to the tape wrapping device 400.

[0058] The structures of the first rotating mechanism 140 and the second rotating mechanism 160 are the same or similar. The first rotating mechanism 140 includes a third rotation driving mechanism and an L-shaped block provided at the output end of the third rotation driving mechanism. The output end of the third rotation driving mechanism is parallel to the front-back direction, the plane where the L-shaped block is located is perpendicular to the front-back direction, and the semi-finished product can be placed on either end of the L-shaped block.

[0059] Refer to Figure 3 and Figure 4 In some of the embodiments, the welding mechanism 310 further includes a first bracket 314, a first front-back driving mechanism 315 and a second lifting driving mechanism 316. The first bracket 314 is provided on the frame 100, the first front-back driving mechanism 315 is provided on the first bracket 314, the second lifting driving mechanism 316 is provided at the output end of the first front-back driving mechanism 315, and the output end of the second lifting driving mechanism 316 is connected to the welding head 311. The first bracket 314 supports the first front-back driving mechanism 315, the second lifting driving mechanism 316 and the welding head 311. The first front-back driving mechanism 315 drives the second lifting driving mechanism 316 and the welding head 311 to move in the front-back direction, so as to adjust the front-back position of the welding head 311, so that the welding head 311 can be directly above the semi-finished product fixture 340 or avoid being directly above the semi-finished product fixture 340. The second lifting driving mechanism 316 drives the welding head 311 to move in the up-down direction, so that the welding head 311 can press the end of the wire against the copper skin layer, and then weld the end of the wire to the copper skin layer.

[0060] It can be conceived that the welding head 311 includes a soldering iron and a wire feeding mechanism. The wire feeding mechanism feeds a welding wire, such as a tin wire, below the soldering iron. The welding wire abuts against the copper skin layer. The soldering iron descends to melt part of the welding wire on the copper skin layer. The melted welding wire connects the end of the wire and the copper skin layer. After the melted welding wire solidifies, a solder joint is formed.

[0061] Referring to Figure 4 and Figure 5 , in some of these embodiments, the welding mechanism 310 further includes a second front-back driving mechanism 317, a third lifting driving mechanism 318, and a fourth lifting driving mechanism 319. The second front-back driving mechanism 317 is disposed on the first bracket 314. The third lifting driving mechanism 318 is disposed on the output end of the first front-back driving mechanism 315. The fourth lifting driving mechanism 319 is disposed on the output end of the third lifting driving mechanism 318. Both the first pressing head 312 and the second pressing head 313 are disposed on the output end of the fourth lifting driving mechanism 319.

[0062] The first bracket 314 supports the second front-back driving mechanism 317, the third lifting driving mechanism 318, the fourth lifting driving mechanism 319, the first pressing head 312, and the second pressing head 313. The second front-back driving mechanism 317 drives the third lifting driving mechanism 318, the fourth lifting driving mechanism 319, the first pressing head 312, and the second pressing head 313 to move in the front-back direction, so as to adjust the front-back positions of the first pressing head 312 and the second pressing head 313. Both the third lifting driving mechanism 318 and the fourth lifting driving mechanism 319 can drive the first pressing head 312 and the second pressing head 313 to move in the up-down direction, so as to adjust the heights of the first pressing head 312 and the second pressing head 313, so that the first pressing head 312 presses the front end of the wire against the copper skin layer with an appropriate force, and the second pressing head 313 presses the semi-finished product against the semi-finished product fixture 340 with an appropriate force. It can be understood that one of the third lifting driving mechanism 318 and the fourth lifting driving mechanism 319 is used to finely adjust the heights of the first pressing head 312 and the second pressing head 313, and the other is used to drive the first pressing head 312 and the second pressing head 313 to move a larger stroke, so that the first pressing head 312 can quickly press the front end of the wire against the copper skin layer or quickly move the first pressing head 312 away from the semi-finished product, so that the second pressing head 313 can quickly press the semi-finished product against the semi-finished product fixture 340 or quickly move the second pressing head 313 away from the semi-finished product.

[0063] Referring to Figure 5 , a fourth front-back driving mechanism is provided on the first bracket 314. A positioning jaw 380 is provided at the output end of the fourth front-back driving mechanism. The fourth front-back driving mechanism drives the positioning jaw 380 to move in the front-back direction. The positioning jaw 380 is used to clamp the semi-finished product on the semi-finished product fixture 340, so as to fix the position of the semi-finished product and keep the semi-finished product stable. The welding jump wire device 300 can then weld jump wires to the semi-finished product.

[0064] It can be understood that the positioning jaws 380 are arranged at a position close to the welding jumper wire station, and the positioning jaws 380 clamp the semi-finished products on the semi-finished product fixture 340 at the welding jumper wire station. In this embodiment, two semi-finished product fixtures 340 are arranged at each end of the carrier plate 360, and the two semi-finished product fixtures 340 are in transmission connection so that the two semi-finished product fixtures 340 rotate synchronously. Correspondingly, the number of the positioning jaws 380 is also two.

[0065] Refer to Figure 7 , in some of the embodiments, the wire feeding mechanism 330 includes a transfer plate 331, a third front-back driving mechanism 332, and a wire chuck 333. The output end of the driving mechanism 320 is connected to the transfer plate 331. The wire outlet pipe 334 and the third front-back driving mechanism 332 are both arranged on the transfer plate 331. The output end of the third front-back driving mechanism 332 is connected to the wire chuck 333. The wire outlet pipe 334 and the wire chuck 333 are distributed front and back. The wire chuck 333 is used for clamping the wire. The third front-back driving mechanism 332 drives the wire chuck 333 to move forward so that the wire passes through the hole of the wire outlet pipe 334.

[0066] The driving mechanism 320 drives the transfer plate 331, the third front-back driving mechanism 332, the wire chuck 333, and the wire clamped by the wire chuck 333 to move in the front-back, left-right, and up-down directions, so as to drive the wire to move in space. The third front-back driving mechanism 332 can drive the wire chuck 333 to move in the front-back direction. When the wire chuck 333 clamps the wire, the third front-back driving mechanism 332 drives the wire chuck 333 to move forward, so that the wire moves towards the wire outlet pipe 334. The wire passes through the hole of the wire outlet pipe 334 and moves forward, so that the front end of the wire can abut against the copper skin layer of the semi-finished product. The wire chuck 333 releases the wire, and the third front-back driving mechanism 332 drives the wire chuck 333 to move backward. The wire chuck 333 resets and can clamp the wire again to drive the wire to pass through the hole of the wire outlet pipe 334 and move forward again.

[0067] In some of the embodiments, the wire chuck 333 includes an upper clamping block, a fifth lifting driving mechanism, and a lower clamping block that are all arranged on the output end of the third front-back driving mechanism 332. The output end of the fifth lifting driving mechanism is connected to the upper clamping block. The upper clamping block is arranged above the lower clamping block. A gap for the wire to pass through is formed between the upper clamping block and the lower clamping block. When the fifth lifting driving mechanism drives the upper clamping block to rise, a gap for the wire to pass through is formed between the upper clamping block and the lower clamping block. When the fifth lifting driving mechanism drives the upper clamping block to move downward, the upper clamping block and the lower clamping block will clamp the wire.

[0068] In this embodiment, the number of both the wire chuck 333 and the wire outlet pipe 334 is two.

[0069] Refer to Figure 1 andFigure 2 , in some of these embodiments, a semi-finished product loading device 500, a blanking device 600, a tray arranging device 700, an inspection device 800 and a defective product trough plate 170 are further provided on the rack 100. The semi-finished product loading device 500 is used to load semi-finished products onto the copper-clad device 200. The blanking device 600 is used to transport the semi-finished products that have completed rubber coating on the rubber coating device 400, that is, the finished products, onto the inspection device 800. The inspection device 800 detects the conduction condition of the winding. If the winding of the finished product is conductive, it is a good product; if the winding of the finished product is non-conductive, it is a defective product. The blanking device 600 orderly discharges the good products into the tray, and the blanking device 600 transports the defective products to the defective product trough plate 170. The first transfer device 110, the second transfer device 120, the first handling mechanism 130, the second handling mechanism 150, the driving mechanism 320, the semi-finished product loading device 500, the blanking device 600, the tray arranging device 700 and the inspection device 800 are all common devices, mechanisms or structures, and no redundant introduction will be made here.
