[0019] 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. Those skilled in the art can reasonably determine the specific meaning of the above words in the present invention in combination with the specific content of the technical solution.

[0020] The semi-finished product of the transformer includes a skeleton and windings wound around the skeleton. The skeleton is in a shape of a Chinese character 'Ri'. The terminals connected to the windings are fixed on the end face of the skeleton. 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 skeleton. It is necessary to wind copper skin layers on the four sides of the skeleton, connect the copper skin layers and a terminal through jumper wires. This one terminal is also called the fixed terminal, that is, the two ends of the jumper wire are respectively connected to the copper skin layer and the fixed terminal. Finally, a tape is wrapped outside the copper skin layer, and the tape covers the solder joints between the copper skin layer and the jumper wire.

[0021] Refer to Figure 1 and Figure 2The present invention discloses a transformer flying lead welding device, comprising: a frame 100, a copper-clad device 200 and a flying lead welding device 300. The frame 100 is provided with a first transfer device 110. The copper-clad device 200 is used to coat the semi-finished product skeleton with a copper layer.

[0022] Reference Figures 3 to 7 The welding wire device 300 includes a welding mechanism 310, a driving mechanism 320, a wire feeding mechanism 330 and a semi-finished product fixture 340. The first transfer device 110 is used to transfer the semi-finished product coated with the copper skin layer to the semi-finished product fixture 340. The wire feeding mechanism 330 is arranged behind the semi-finished product fixture 340. The wire feeding mechanism 330 includes a wire outlet tube 334 extending in the front-to-back direction. The wire outlet tube 334 is used to send out the wire. The driving mechanism 320 is arranged on the frame 100. The driving mechanism 320 is used to drive the wire outlet tube 334 to move in the front-to-back, left-to-right and up-and-down directions so that the front end of the wire The semi-finished product is placed on the copper skin layer of the semi-finished product on the semi-finished product fixture 340, and the wire of the semi-finished product on the semi-finished product fixture 340 is wound around the fixed terminal. The welding mechanism 310 includes a welding head 311, a first pressure head 312 and a second pressure head 313, which can all be raised and lowered. The first pressure 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 to the copper skin layer, the second pressure head 313 moves down to press the semi-finished product tightly on the semi-finished product fixture 340, and the wire outlet tube 334 drives the wire to move so that the wire is wound around the fixed terminal and is pulled apart, and a flying wire is welded on the semi-finished product.

[0023] When the transformer flying wire welding equipment is working, the welding mechanism 310 is in a high position, and the wire feeding mechanism 330 is at the rear of 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-clad device 200, and the copper-clad device 200 wraps a copper layer around the four sides of the skeleton of the semi-finished product; then the first transfer device 110 transports the semi-finished product covered with the copper layer to the semi-finished product fixture 340; then the driving mechanism 320 drives the outlet tube 334 to move in the front-to-back, left-to-right and up-and-down directions, that is, the outlet tube 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 fed out of the outlet tube 334 rest on the copper layer of the semi-finished product; then the first pressure head 312 moves down to press the front end of the wire on the copper layer, and the welding head 311 moves down to weld the end of the wire. Connected to the copper layer, the second pressure head 313 moves downward to press the semi-finished product on the semi-finished product fixture 340; then the driving mechanism 320 drives the outlet tube 334 to move in the front-to-back, left-to-right and up-and-down directions again, and the wire sent out of the outlet tube 334 is wound around the fixed terminal, and then the outlet tube 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 outlet tube 334 is disconnected, completing the connection of the semi-finished flying wire, that is, completing the welding flying wire; finally, the welding mechanism 310 moves upward, and the wire feeding mechanism 330 moves backward to avoid the semi-finished product fixture 340 from being blocked, and then the semi-finished product with welded flying wires can be taken away.

[0024] It should be understood that when welding flying wires to the semi-finished product, the axis of the fixed terminal on the semi-finished product is parallel to the front-to-back direction, and the outlet tube 334 drives the wire to wrap around the fixed terminal. At this time, the direction of the wire sent out by the outlet tube 334 is perpendicular to the axial direction of the fixed terminal. The outlet tube 334 moves in a direction perpendicular to the axial direction of the fixed terminal so that the wire in the outlet tube 334 and the wire between the outlet tube 334 and the fixed terminal are at right angles or acute angles. Under the action of the fixed terminal and the side wall of the outlet tube 334, the wire sent out by the outlet tube 334 between the fixed terminal and the outlet tube 334 will be pulled apart, and the broken end of the wire output by the outlet tube 334 is near the outlet of the outlet tube 334, and this end becomes the new end of the wire.

[0025] Reference Figure 1 and Figure 2 In some embodiments, the transformer flying wire welding equipment also includes a second transfer device 120 and a glue coating device 400, both of which are arranged on the frame 100. The second transfer device 120 is used to transfer the semi-finished product with welded flying wires to the glue coating device 400. The glue coating device 400 is used to coat the copper layer of the semi-finished product with tape. The tape is coated on the copper layer and covers the welding point between the flying wire and the copper layer, so as to finally obtain the desired finished product.

[0026] It is understandable that the structures of the copper-clad device 200 and the rubber-clad device 400 are the same or similar. The rubber-clad device 400 is a common device or apparatus or mechanism, and no redundant introduction is made here.

[0027] In another embodiment, the transformer flying wire welding equipment also includes a spot welding device, which is arranged between the flying wire welding device 300 and the rubber coating device 400. The semi-finished product with welded flying wire is transferred to the spot welding device, and the spot welding device welds the flying wire and the fixed terminal together. Then, the semi-finished product after the flying wire and the fixed terminal are welded together is transferred to the rubber coating device 400, and the rubber coating device 400 coats the copper skin layer of the semi-finished product with rubber.

[0028] Reference Figure 3 and Figure 6 In some embodiments, the welding flying wire device 300 also includes a first rotary drive mechanism 350 and a carrier plate 360, the first rotary drive mechanism 350 is arranged on the frame 100, the carrier plate 360 ​​can be rotatably arranged on the frame 100 around a vertical axis, the output end of the first rotary drive mechanism 350 is transmission-connected with the carrier plate 360, both ends of the carrier plate 360 ​​are provided with semi-finished product fixtures 340, the frame 100 is provided with a first loading and unloading station and a welding flying wire station distributed front and back, the first transfer device 110 and the second transfer device 120 are both arranged on the first loading and unloading station, and the welding flying wire device 300 is arranged on the welding flying wire station.

[0029] The carrier plate 360 ​​is arranged horizontally, and the middle area of ​​the carrier plate 360 ​​is connected to the frame 100 through the first bearing. When the transformer welding flying lead equipment is working, the two ends of the carrier plate 360 ​​correspond to the first loading and unloading station and the welding flying lead station, that is, the areas corresponding to the first loading and unloading station and the welding flying lead station are both provided with a semi-finished product fixture 340. At the welding flying lead station, the welding flying lead device 300 welds the flying lead to the semi-finished product on the semi-finished product fixture 340, while at the first loading and unloading station, the second transfer device 120 takes away the semi-finished product with the flying lead welded on the semi-finished product fixture 340, and then the first transfer device 110 loads a semi-finished product to be welded with the flying lead to the semi-finished product fixture 340, which can effectively improve the efficiency of welding the flying lead.

[0030] Reference Figure 2 In some embodiments, the frame 100 is provided with a first conveying mechanism 130 and a first rotating mechanism 140 in the area between the copper cladding device 200 and the welding wire device 300, and the first conveying mechanism 130 is used to convey the semi-finished product on the copper cladding device 200 to the first rotating mechanism 140.

[0031] It is understandable that when the copper-cladding device 200 covers the semi-finished product with a copper layer, the 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 fixed terminal of the semi-finished product is at the highest position of the semi-finished product, and 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, and will not change the position of the semi-finished product. When welding a flying wire to a given terminal, the end face of the semi-finished product with the fixed terminal must face backward, the fixed terminal is parallel to the front and rear direction, and one side of the semi-finished product and the copper layer thereon face upward, so that it is convenient for the outlet tube 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 copper layer area.

[0032] The first rotating mechanism 140 is used to drive the semi-finished product to rotate 90° in the forward and backward direction as the rotation axis so that the end face of the semi-finished product with the fixed terminal faces right or left, and 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.

[0033] 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 with a fixed terminal at the welding flying wire station is facing left or right, and the semi-finished product needs to be rotated 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 be rotated 90° with the vertical direction as the rotation axis, so that the end face of the semi-finished product with a fixed terminal faces backwards.

[0034] Reference Figure 6 In some embodiments, the welding flying wire device 300 also includes a first lifting drive mechanism 370, which is arranged in the area of ​​the frame 100 corresponding to the welding flying wire station, and the output end of the first lifting drive mechanism 370 is connected to the second rotation drive mechanism 371, and the output end of the second rotation drive mechanism 371 is provided with a clamping head. The semi-finished product fixture 340 can be rotatably arranged on the carrier plate 360 ​​with the vertical direction as the rotation axis, and the lower end of the semi-finished product fixture 340 is provided with a slot. The first lifting drive mechanism 370 drives the second rotation drive mechanism 371 to rise so that the clamping head is inserted into the slot, and 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.

[0035] It can be understood that the carrier plate 360 ​​is provided with a mounting hole penetrating the upper and lower surfaces of the carrier plate 360, and a second bearing is provided in the mounting hole, 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 realize self-rotation on the carrier plate 360. The lower end of the semi-finished product fixture 340 extends to the bottom of the carrier plate 360, and the card slot is provided below the carrier plate 360, and the card slot is provided at the rotation axis of the semi-finished product fixture 340.

[0036] Initially, the first lifting drive mechanism 370 drives the second rotating drive mechanism 371 and the chuck to descend, and the chuck is in a 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. The semi-finished product fixture 340 at the welding flying wire station is facing the chuck, and the first lifting drive mechanism 370 drives the second rotating drive mechanism 371 and the chuck to rise, so that the chuck is inserted into the slot. Then the second rotating drive mechanism 371 drives the semi-finished product fixture 340 to rotate 90° with the vertical direction as the rotation axis through the matching chuck and the slot. The semi-finished product fixture 340 carries the semi-finished product and rotates 90° with the vertical direction as the rotation axis, so that the axial direction of the fixed terminal is parallel to the front and rear directions, that is, the end face of the semi-finished product with the fixed terminal faces backwards, and the fixed terminal on the semi-finished product is close to the wire feeding mechanism 330, and the welding flying wire device 300 can weld flying wires to the semi-finished product.

[0037] After the semi-finished product has completed the welding of the flying wires, the second rotary drive mechanism 371 drives the semi-finished product fixture 340 to rotate 90° in the opposite direction with the vertical direction as the rotation axis through the matching clamp and the clamping slot. The first lifting drive mechanism 370 drives the second rotary drive mechanism 371 and the clamping head to descend, so that the clamping head and the clamping slot are disengaged, and 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 of the flying wires returns to the first loading and unloading station, and the posture of the semi-finished product that has completed the welding of the flying wires returning to the first loading and unloading station is consistent with the posture of the semi-finished product when it was initially transported to the first loading and unloading station, and the semi-finished product to be welded at the first loading and unloading station is transferred to the welding flying wire station.

[0038] Reference Figure 2 In some embodiments, the frame 100 is provided with a second conveying mechanism 150 and a second rotating mechanism 160 in the area between the welding wire device 300 and the rubber encapsulation device 400, and the second conveying mechanism 150 is used to convey the semi-finished product on the semi-finished product fixture 340 to the second rotating mechanism 160.

[0039] It is understandable that when the rubber coating device 400 coats the semi-finished product with adhesive tape, the four sides of the semi-finished product need to remain parallel to the vertical direction, the axial direction of the fixed terminal of the semi-finished product is parallel to the vertical direction, and the fixed terminal is at the highest position of the semi-finished product. When the second transport mechanism 150 and the second transfer device 120 transport the semi-finished product, the semi-finished product will not be rotated, that is, the posture of the semi-finished product will not be changed, only the position of the semi-finished product will be changed. When the copper coating device 200 coats the semi-finished product with adhesive tape, the posture of the semi-finished product needs to be the same as that on the rubber coating device 400, the 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 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.

[0040] The second rotating mechanism 160 is used to drive the semi-finished product to rotate 90° with the front-to-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 cladding device 200. The second transfer device 120 is used to transfer the semi-finished product on the second rotating mechanism 160 to the rubber coating device 400.

[0041] 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 rotating drive mechanism and an L-shaped block arranged at the output end of the third rotating drive mechanism. The output end of the third rotating drive mechanism is parallel to the front-to-back direction, and the plane where the L-shaped block is located is perpendicular to the front-to-back direction. The semi-finished product can be placed on either end of the L-shaped block.

[0042] Reference Figure 3 and Figure 4 In some embodiments, the welding mechanism 310 further includes a first bracket 314, a first front-rear driving mechanism 315, and a second lifting driving mechanism 316. The first bracket 314 is disposed on the frame 100, the first front-rear driving mechanism 315 is disposed on the first bracket 314, and the second lifting driving mechanism 316 is disposed on the output end of the first front-rear driving mechanism 315. 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-rear driving mechanism 315, the second lifting driving mechanism 316, and the welding head 311. The first front-to-back driving mechanism 315 drives the second lifting driving mechanism 316 and the welding head 311 to move in the front-to-back direction, so as to adjust the front-to-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, and 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 place the end of the wire against the copper layer, and then weld the end of the wire to the copper layer.

[0043] It can be imagined that the welding head 311 includes an electric soldering iron and a soldering wire feeding mechanism. The soldering wire feeding mechanism feeds a soldering wire, such as a tin wire, under the electric soldering iron. The soldering wire is against the copper skin layer. The electric soldering iron descends to melt part of the soldering wire on the copper skin layer. The melted soldering wire connects the end of the wire and the copper skin layer. The melted soldering wire solidifies to form a solder joint.

[0044] Reference Figure 4 and Figure 5 In some embodiments, the welding mechanism 310 also includes a second front-to-back driving mechanism 317, a third lifting driving mechanism 318 and a fourth lifting driving mechanism 319, the second front-to-back driving mechanism 317 is arranged on the first bracket 314, the third lifting driving mechanism 318 is arranged on the output end of the first front-to-back driving mechanism 315, the fourth lifting driving mechanism 319 is arranged on the output end of the third lifting driving mechanism 318, and the first pressing head 312 and the second pressing head 313 are both arranged on the output end of the fourth lifting driving mechanism 319.

[0045] The first bracket 314 supports the second front-to-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-to-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-to-back direction to adjust the front-to-back positions of the first pressing head 312 and the second pressing head 313. The third lifting driving mechanism 318 and the fourth lifting driving mechanism 319 can both drive the first pressing head 312 and the second pressing head 313 to move in the up-down direction to adjust the height 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 on the copper layer with an appropriate force, and the second pressing head 313 presses the semi-finished product on the semi-finished product fixture 340 with an appropriate force. It can be understood that one of the third lifting drive mechanism 318 and the fourth lifting drive mechanism 319 is used to fine-tune the height of the first press head 312 and the second press head 313, and the other is used to drive the first press head 312 and the second press head 313 to move a larger stroke, so that the first press head 312 can quickly press the front end of the wire on the copper layer or make the first press head 312 quickly move away from the semi-finished product, so that the second press head 313 can quickly press the semi-finished product on the semi-finished product fixture 340 or make the second press head 313 quickly move away from the semi-finished product.

[0046] Reference Figure 5 A fourth front-to-back driving mechanism is provided on the first bracket 314, and a positioning clamp 380 is provided at the output end of the fourth front-to-back driving mechanism. The fourth front-to-back driving mechanism drives the positioning clamp 380 to move along the front-to-back direction. The positioning clamp 380 is used to clamp the semi-finished product on the semi-finished product fixture 340, so that the position of the semi-finished product is fixed and the semi-finished product is kept stable. The flying wire welding device 300 can weld flying wires to the semi-finished product.

[0047] It can be understood that the positioning jaws 380 are arranged near the welding flying line station, and the positioning jaws 380 clamp the semi-finished product on the semi-finished product fixture 340 at the welding flying line 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 transmission-connected so that the two semi-finished product fixtures 340 rotate synchronously, and accordingly, the number of the positioning jaws 380 is also two.

[0048] Reference Figure 7 In some embodiments, the wire feeding mechanism 330 includes an adapter plate 331, a third front-to-back driving mechanism 332 and a wire clamp 333, the output end of the driving mechanism 320 is connected to the adapter plate 331, the outlet tube 334 and the third front-to-back driving mechanism 332 are both arranged on the adapter plate 331, the output end of the third front-to-back driving mechanism 332 is connected to the wire clamp 333, the outlet tube 334 and the wire clamp 333 are distributed front and back, the wire clamp 333 is used to clamp the wire, and the third front-to-back driving mechanism 332 drives the wire clamp 333 to move forward so that the wire passes through the tube hole of the outlet tube 334.

[0049] The driving mechanism 320 drives the adapter plate 331, the third front-to-back driving mechanism 332, the wire clamp 333 and the wire clamped on the wire clamp 333 to move in the front-to-back, left-to-right and up-and-down directions, so as to drive the wire to move in space. The third front-to-back driving mechanism 332 can drive the wire clamp 333 to move in the front-to-back direction. When the wire clamp 333 clamps the wire, the third front-to-back driving mechanism 332 drives the wire clamp 333 to move forward, so that the wire moves toward the outlet tube 334, and the wire passes through the tube hole of the outlet tube 334 and moves forward, so that the front end of the wire can be against the copper layer of the semi-finished product, and the wire clamp 333 releases the wire, and the third front-to-back driving mechanism 332 drives the wire clamp 333 to move backward. The wire clamp 333 is reset and can clamp the wire again to drive the wire to pass through the tube hole of the outlet tube 334 and move forward again.

[0050] In some of the embodiments, the wire clamp 333 includes an upper clamping block, a fifth lifting drive mechanism and a lower clamping block both disposed on the output end of the third front-rear drive mechanism 332, the output end of the fifth lifting drive mechanism being connected to the upper clamping block, the upper clamping block being disposed above the lower clamping block, and a gap between the upper clamping block and the lower clamping block for the wire to pass through. When the fifth lifting drive mechanism drives the upper clamping block to rise, a gap is formed between the upper clamping block and the lower clamping block for the wire to pass through, and when the fifth lifting drive mechanism drives the upper clamping block to move downward, the upper clamping block and the lower clamping block will clamp the wire.

[0051] In this embodiment, the number of the wire clamps 333 and the number of the wire outlet tubes 334 are both two.

The semi-finished product loading device 500 is used to load the semi-finished product onto the copper cladding device 200. The unloading device 600 is used to transport the semi-finished product that has been completed by the rubber coating device 400, that is, the finished product to the detection device 800. The detection device 800 detects the conductivity of the winding. The finished product with conductive winding is a good product, and the finished product with non-conductive winding is a defective product. The unloading device 600 arranges the good products into the tray in an orderly manner, and the unloading device 600 transports the defective products to the defective product slot plate 170.
