Description

Technical Field

[0001] The present invention relates to the technical field of transformer coil processing, and specifically provides a processing device for vehicle transformers. Background Art

[0002] A transformer is a soft magnetic electromagnetic component, whose functions include power transmission, voltage transformation, and insulation isolation. It is widely used in power supply technology and power electronics technology. A transformer is an important component in new energy electric vehicles. For some models of transformers, both ends of the coil need to be led out of the housing and used as pins, and the pins need to be tinned to achieve the functions of anti-corrosion and easy soldering. Most of the existing tinning methods require manual operation. When tinning, first, manually fit multiple coils onto the tooling fixture, then align and clamp them. Subsequently, the operator holds the tooling fixture, first immerses the pins of the coil in the flux, and then immerses the pins of the coil in the molten tin. The working efficiency of the manual operation method is relatively low, the technical requirements for the operator are relatively high, and it is easy to scald the staff.

[0003] Therefore, providing a device that can improve the processing efficiency of vehicle transformer coils is a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a processing device for vehicle transformers, which solves the technical problem of low production efficiency due to manual operation when tinning the pins of vehicle transformer coils in the prior art.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A vehicle transformer coil processing device includes a base, on which a central rod is fixedly arranged. A rotating cylinder is rotatably arranged outside the central rod. Four hanging rods are evenly and fixedly arranged on the side wall of the rotating cylinder along its circumferential direction. Pressure plates are slidably arranged above each of the hanging rods on the side wall of the rotating cylinder. The pressure plates are used to press the coils on the hanging rods. A pair of coil aligning rods are fixedly connected by a plurality of connecting rods under both sides of the pressure plates. A flux tank and a tin bath are arranged on the base. Electric telescopic rods are installed between the bottoms of the flux tank and the tin bath and the base. The flux tank and the tin bath can be vertically aligned with two adjacent ones among the four hanging rods. A scraper is slidably arranged in the tin bath. A worm gear ring is fixedly arranged outside the bottom of the rotating cylinder. A motor I is fixedly arranged on the base. A worm is fixedly arranged at the power output end of the motor I. The worm meshes with the worm gear ring. An installation groove is formed on the upper surface of the hanging rod. A plurality of installation shafts are fixedly arranged in the installation groove. A plurality of clamping blocks are hinged on the plurality of installation shafts. An arc part and a limiting part are respectively arranged at both ends of each clamping block. The weight of one end of the limiting part is greater than that of one end of the arc part. When the clamping block is in a natural state, the limiting part can be in the installation groove while the upper end of the arc part protrudes out of the installation groove. When the coil moves above the arc part, the weight of the coil can press the arc part into the installation groove, and at the same time, the limiting part moves out of the installation groove. The limiting part moving out of the installation groove can limit the coil, so that the coil is above the arc part at one end of the front clamping block. A convex block is fixedly arranged outside one end of the installation groove. A plurality of pairs of limiting strips are fixedly arranged on the lower surface of the pressure plate. Each pair of limiting strips is vertically corresponding to the arc part in the clamping block. The distance between a pair of limiting strips matches the thickness of the coil.

[0006] Preferably, a sliding groove is formed on the side wall of the rotating cylinder. The cross section of the sliding groove is T-shaped. A sliding block with a shape matching that of the sliding groove is slidably arranged in the sliding groove. One end of the pressure plate is fixedly arranged on the sliding block. A spring is arranged at the bottom of the sliding groove. The spring is used to push the sliding block to move upward.

[0007] Preferably, a semi-circular limiting ring is fixedly arranged on one side above the flux tank and the tin bath near the top of the central rod. Both ends of the semi-circular limiting ring are inclined planes. A pulley is rotatably arranged above the pressure plate. When the rotating cylinder drives the pressure plate to move circumferentially, the pulley can move under the semi-circular limiting ring through the inclined plane.

[0008] Preferably, chamfers are formed at the bottoms of each pair of limiting strips.

[0009] Preferably, a lead screw is rotatably arranged on one side of the tin bath, a smooth rod is fixedly arranged on the other side of the tin bath, one end of the scraping plate is slidably connected to the smooth rod, the other end of the scraping plate is threadedly connected to the lead screw, and a second motor for driving the rotation of the lead screw is fixedly arranged outside the tin bath.

[0010] The present invention provides a processing device for vehicle transformers, which has the following beneficial effects: By arranging four hanging rods on the rotating cylinder, four workstations can be formed, namely the feeding area, the flux application area, the tinning area, and the discharging area. The operations between the workstations do not affect each other, and the feeding, flux application, tinning, and discharging processes can be carried out simultaneously, improving work efficiency. By arranging clamping blocks on the hanging rods, the coils can be preliminarily limited during installation, ensuring that there is a gap between each coil and preventing two adjacent coils from colliding with each other. Through the cooperation of the semi-circular limiting ring and the pulley on the pressing plate, when the pressing plate moves above the flux bath and the tin bath, the pressing plate will automatically descend, and the coils are fixed by the descent of the pressing plate to ensure that the pins are in a vertical state. When the pressing plate moves out of the semi-circular limiting ring, the spring can push the slider and the pressing plate to rise, facilitating the loading and unloading operations on the hanging rod without manual operation.

Detailed implementation manners

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] Please refer to Figures 1-9, the present invention provides a technical solution: a vehicle transformer coil processing device, including a base 1, a central rod 2 is fixedly arranged on the base 1, a rotating cylinder 3 is rotatably arranged outside the central rod 2, and four hanging rods 4 are fixedly arranged on the side wall of the rotating cylinder 3 along its circumferential direction. Each hanging rod 4 can hang multiple coils 30. Four working stations can be formed through the four hanging rods 4, namely a loading area, a fluxing agent application area, a soldering area, and a unloading area. Sliding plates 7 are slidably arranged above each hanging rod 4 on the side wall of the rotating cylinder 3. The sliding plates 7 are used to press the coils 30 on the hanging rods 4. A pair of coil aligning rods 8 are fixedly connected to the lower sides of both sides of the sliding plates 7 through a plurality of connecting rods 22. When the sliding plates 7 press the coils 30, a pair of coil aligning rods 8 can abut against both sides of the multiple coils 30 to align the multiple coils 30 and ensure that the pins of the coils 30 are in a vertical state. A fluxing agent tank 9 and a molten tin tank 10 are arranged on the base 1. The fluxing agent tank 9 is used to store fluxing agent, and the molten tin tank 10 is used to store molten tin. The molten tin tank 10 can be heated to ensure that the molten tin contained therein will not cool and solidify. Electric telescopic rods 27 are installed between the bottoms of the fluxing agent tank 9 and the molten tin tank 10 and the base 1. The fluxing agent tank 9 and the molten tin tank 10 can be vertically aligned with two adjacent ones of the four hanging rods 4, corresponding to the fluxing agent application area and the soldering area respectively. The fluxing agent tank 9 or the molten tin tank 10 can be lifted by the electric telescopic rod 27. When the fluxing agent tank 9 rises, the coil pins can be immersed in the stored fluxing agent. When the molten tin tank 10 rises, the coil pins can be immersed in the stored molten tin. The depth of the coil pins immersed in the liquid is controlled by controlling the rising height of the tank body. A scraper 25 is slidably arranged in the molten tin tank 10. The scraper can be inserted into the molten tin. Before soldering, the film formed by cooling and solidification on the surface of the molten tin can be scraped to one side by sliding the scraper 25 to ensure that the pins can contact the fully melted molten tin and ensure the soldering effect. A worm gear ring 12 is fixedly arranged outside the bottom of the rotating cylinder 3, and a motor 13 is fixedly arranged on the base 1. A worm 14 is fixedly arranged at the power output end of the motor 13. The worm 14 meshes with the worm gear ring 12. After the motor 13 is powered on, the worm 14 can rotate. Through the meshing of the worm 14 and the worm gear ring 12 to form the transmission of power, the rotating cylinder 3 can rotate.

[0023] Please refer to Figures 3-4 , as an embodiment of the present invention, a chute 5 is opened on the side wall of the rotating cylinder 3. The cross section of the chute 5 is T-shaped, and a slider 6 with a shape matching that of the chute 5 is slidably arranged in the chute 5. One end of the sliding plate 7 is fixedly arranged on the slider 6. The movement track of the sliding plate 7 can be restricted through the cooperation of the slider 6 and the chute 5. A spring 28 is arranged at the bottom of the chute 5. The spring 28 is used to push the slider 6 upward. In the natural state, the sliding plate 7 can be pushed away from the hanging rod 4 by the spring 28 pushing the slider 6 upward, which is convenient for installing coils on the hanging rod 4.

[0024] Please refer to Figures 1-4, as an embodiment of the present invention, a semi-circular limit ring 11 is fixedly arranged above one side of the top of the central rod 2 near the flux tank 9 and the tin bath 10. Both ends of the semi-circular limit ring 11 are inclined surfaces. A pulley 20 is rotatably arranged above the pressing plate 7. When the rotating cylinder 3 drives the pressing plate 7 to move circumferentially, the pulley 20 can move to the lower part of the semi-circular limit ring 11 through the inclined surface, so as to realize the descent of the pressing plate 7, and the highest position of the pulley 20 is limited by the semi-circular limit ring 11.

[0025] Please refer to Figures 6-7 , as an embodiment of the present invention, mounting grooves 15 are formed on the upper surface of the hanging rod 4. A plurality of mounting shafts 16 are fixedly arranged in the mounting grooves 15. A plurality of clamping blocks 17 are hinged on the plurality of mounting shafts 16. Arc portions 18 and limiting portions 19 are respectively arranged at both ends of each clamping block 17. The weight of one end of the limiting portion 19 is greater than that of one end of the arc portion 18. When the clamping block 17 is in a natural state, the limiting portion 19 can be in the mounting groove 15 while the upper end of the arc portion 18 protrudes out of the mounting groove 15. When the coil moves above the arc portion 18, the weight of the coil can press the arc portion 18 into the mounting groove 15, and at the same time, the limiting portion 19 moves out of the mounting groove 15. The limiting portion 19 moving out of the mounting groove 15 can limit the coil, so that the coil 30 is above the arc portion 18 at one end of the front clamping block 17. In addition, because the arc portion 18 has an arc surface, when the coil 30 needs to pass through the arc portion 18, the arc portion 18 can be pressed down by the contact between the coil 30 and the arc surface of the arc portion 18, ensuring that the coil 30 can move arbitrarily on the hanging rod 4. A convex block 29 is fixedly arranged outside one end of the mounting groove 15. The first coil 30 sleeved on the hanging rod 4 is limited by the convex block 29, so that the first coil 30 is above the arc portion 18 inside the first clamping block 17.

[0026] Please refer to Figure 8 , as an embodiment of the present invention, a plurality of pairs of limiting strips 21 are fixedly arranged on the lower surface of the pressing plate 7. Each pair of limiting strips 21 corresponds vertically to the arc portion 18 in the clamping block 17. The distance between a pair of limiting strips 21 matches the thickness of the coil 30. When the pressing plate 7 descends, the limiting strips 21 can be sleeved on both sides of the coil 30, preventing the coil 30 from moving along the length direction of the hanging rod 4, ensuring that there is a gap between each coil 30. Chamfers are formed at the bottom of each pair of limiting strips 21. The chamfers can play a guiding role, facilitating the limiting strips 21 to still be sleeved outside the coil 30 when there is a small offset in the relative position between the coil 30 and the limiting strips 21.

[0027] Please refer to Figure 9, as an embodiment of the present invention, a lead screw 23 is rotatably arranged on one side of the tin bath 10, a smooth rod 24 is fixedly arranged on the other side of the tin bath 10, one end of the scraper 25 is slidably connected to the smooth rod 24, the other end of the scraper 25 is threadedly connected to the lead screw 23, and a second motor 26 for driving the rotation of the lead screw 23 is fixedly arranged outside the tin bath 10. The movement track of the scraper 25 can be restricted by the smooth rod 24, and the rotation of the lead screw 23 driven by the second motor 26 can make the scraper 25 move along its length direction.

[0028] Those skilled in the art shall connect all the electrical components in this case to their adapted power supplies through wires, and should select a suitable controller according to the actual situation to meet the control requirements. For the specific connection and control sequence, reference should be made to the sequence of the electrical components working successively in the following working principle to complete the electrical connection. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of the electrical control will be made.

[0029] Working principle and usage process of the present invention: During use, the coil 30 is sleeved on the hanging rod 4 located in the feeding area. When the first coil 30 contacts the convex block 29, the limiting part 19 of the first clamping block 17 can be moved out of the installation groove 15. When the second coil 30 sleeved contacts the limiting part 19 of the first clamping block 17, the arc part 18 at one end of the second clamping block 17 can be pressed down by the second coil 30, so that the limiting part 19 of the second clamping block 17 can be moved out of the installation groove 15. By analogy, multiple coils 30 are installed on the hanging rod 4. The clamping block 17 can initially limit the length position of each coil 30 on the hanging rod 4, preventing the distance between two adjacent coils 30 from being too close or too far, and avoiding collision between the two coils 30. After the hanging rod 4 in the feeding area is filled with coils 30, the first motor 13 is started. By controlling the number of rotation turns of the first motor 13, the rotation angle of the rotating cylinder 3 can be controlled. The rotating cylinder 3 is driven by the first motor 13 to rotate, so that the hanging rod 4 moves above the flux tank 9. After the movement is completed, the electric telescopic rod 27 below the flux tank 9 can push the flux tank 9 upward, so that the pins 31 at the bottom of the coil 30 are immersed in the flux. After soaking, the flux tank 9 is controlled to descend by the electric telescopic rod 27. The first motor 13 is started again to move the coil 30 soaked with flux above the tin bath 10. Starting the second motor 26 can make the scraper 25 move. The film formed on the upper surface of the tin liquid due to cooling can be scraped to one side by the scraper 25. Subsequently, the tin bath 10 is pushed upward by the electric telescopic rod 27 below the tin bath 10, so that the pins 31 of the coil 30 are immersed in the molten tin liquid to complete tinning. After tinning, the tin bath 10 moves downward, and at the same time, the pins 31 of the coil 30 are exposed to the air for cooling. The first motor 13 is started again to move the tinned coil 30 to the discharging area for discharging, as Figure 7As shown, when blanking, the coils 30 on the hanging rods 4 are removed from the outside to the inside in sequence. Since the arc portion 18 has an arc surface, when the coil 30 contacts the arc surface, it can push the arc portion 18 to move downward, ensuring that when the arc portion 18 extends out of the installation groove 15, the coil 30 can also move freely on the hanging rod 4; by providing four hanging rods 4, four workstations can be formed, and the operations between the workstations do not affect each other, enabling simultaneous feeding, soaking in flux, soldering, and blanking, thus improving work efficiency; in addition, when the pressing plate 7 moves below the semi-circular limiting ring 11, the pulley 20 first contacts the inclined surface at the end of the semi-circular limiting ring 11, and the pulley 20 can be moved below the semi-circular limiting ring 11 through this inclined surface. After the pulley 20 moves below the semi-circular limiting ring 11, the pressing plate 7 can be lowered. After the pressing plate 7 is lowered, the coil 30 can be fixed and limited through the limiting strip 21 and the coil aligning rod 8, while ensuring that the pins 31 of the coil 30 are in a vertical state; since the semi-circular limiting ring 11 is arranged on the upper side close to the flux tank 9 and the molten tin tank 10, when the pressing plate 7 moves above the flux tank 9 and the molten tin tank 10, the pressing plate 7 will be in the lowered state. When the pressing plate 7 moves out of the upper side of the flux tank 9 and the molten tin tank 10, the pulley 20 loses the restraint of the semi-circular limiting ring 11, and the spring 28 can push the slider 6 to rise, so that the pressing plate 7 moves away from the hanging rod 4. At this time, the coil 30 can be loaded or removed on the hanging rod 4. Through this structure, the coil 30 on the hanging rod 4 can be automatically fixed without manual operation.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
