Abstract

The application provides an inductor coil paint removal device, and belongs to the technical field of inductor processing. The device comprises a control cabinet and a paint removal mechanism. The paint removal mechanism comprises a mounting plate fixed to the side of the control cabinet, and a plurality of clamping pieces are slidably connected to the surface of the mounting plate. The paint removal mechanism is provided. After the pins of the inductor coil are inserted between the clamping blocks, the driving assembly drives the clamping blocks to fit on the pins. During this process, if the pins are in a bent state, the clamping blocks can correct the bent pins after fitting on the pins, which facilitates the use of the inductor coil in the later stage. Then, the heating wire can heat the paint on the pins. After heating for a period of time, the pins are pulled out from between the clamping blocks. During the pulling-out process, the protrusions can scrape off the paint on the pins that is softened by heating. During the scraping-off process, the protrusions will not damage the pins, thereby protecting the pins. After the paint is removed, the pins do not need to be cleaned, and the time spent is shorter.

Description

Technical Field

[0001] This invention relates to the field of inductor processing technology, and in particular to an inductor coil paint stripping device. Background Technology

[0002] An inductor is an electromagnetic component that is made of enameled wire wound on a magnetic core or frame. The leads are the ends of the enameled wire. The insulating varnish prevents electrical conduction during soldering. Therefore, the leads of the inductor need to be stripped of the varnish during the production process. There are two main types of varnish stripping devices: physical stripping and chemical stripping. Physical stripping consists of a control cabinet, a motor, and a clamp. When in use, the lead is inserted into the clamp, and the motor drives the clamp to rotate. As the lead is pulled out of the clamp, the rotating clamp scrapes off the insulating varnish on the surface of the lead. Chemical stripping involves immersing the leads of the inductor in a high-temperature chemical reagent. After a period of time, the leads of the inductor are removed from the chemical reagent and placed in a cleaning solution to clean the chemical reagent off the leads.

[0003] During the physical process of removing the paint from the leads of an inductor coil, the clamps can damage the surface of the leads, resulting in an uneven surface. When the leads of an inductor coil are removed chemically, the paint must be removed first, and then the coil must be cleaned, which takes a long time. Therefore, this application provides an inductor coil paint removal device to meet the requirements. Summary of the Invention

[0004] This invention provides an inductor coil paint stripping device to solve the problems of physical paint stripping causing damage to the pin surface and chemical paint stripping requiring a long time.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An inductor coil paint stripping device includes a control cabinet and further includes: The paint stripping mechanism includes a mounting plate fixed to the side of the control cabinet. Multiple clamping members are slidably connected to the surface of the mounting plate. The multiple clamping members are arranged in a circumferential array about the center of the mounting plate. The clamping members are slidably connected to an expansion portion on the surface of the mounting plate. An inclined portion is fixed to the end of the expansion portion. A clamping portion is fixed to the end of the inclined portion. A driving assembly is provided at the inclined portion. The driving assembly is used to drive the multiple clamping members to move closer or further away from each other. A clamping block is fixed to the inner wall of the clamping portion. A guide block is fixed to the end of the guide block. An arc-shaped guide surface is opened at the end of the guide block. A heating wire is fixed inside the clamping block. Multiple protrusions are fixed to the surface of the clamping block.

[0006] Preferably, the surface of the mounting plate is provided with multiple grooves, the inner wall of the grooves is slidably connected to a slider, and the end of the expansion portion is fixed to the surface of the slider.

[0007] Preferably, the drive assembly includes multiple electric push rods fixed to the mounting plate. The output ends of the multiple electric push rods are jointly fixed with a drive ring. The inner wall of the drive ring has a slope three. An inner ring is provided on the inner side of the slope portion. A slope four is provided on the outer side of the inner ring. A support tube is fixed to the end of the inner ring. The support tube is fixed to the mounting plate. An outer pull member is provided on the outer side of the expansion portion. Before paint removal, the electric push rods drive the drive ring closer to the clamping portion. The outer pull member drives the multiple expansion portions away from each other. The slope portion moves away from the slope four. During paint removal, the electric push rods drive the drive ring away from the clamping portion. The inner side of the slope portion is attached to the slope four.

[0008] Preferably, the outer pull member includes multiple mounting seats fixed to the surface of the mounting plate, multiple guide sleeves fixed to the surface of the mounting seats, tension springs fixed to the inner walls of the guide sleeves, T-shaped guide rods fixed to the ends of the tension springs, and the ends of the T-shaped guide rods being movably guided and fixed to the surface of the expansion portion.

[0009] Preferably, the surface of the mounting plate is fixed with multiple round rods, all of which movably pass through the drive ring, and the ends of the multiple round rods are jointly fixed with a ring.

[0010] Preferably, the inner wall of the support tube is provided with a cleaning assembly, which includes an electric push rod two fixed to the inner wall of the support tube. A round block is fixed to the end of the electric push rod two. Multiple bristles are fixed to the surface of the round block. When the clamping parts are far apart, the electric push rod two drives the bristles to slide on the surface of the clamping block and the protrusion through the round block. A rubber conical ring is fixedly sleeved on the surface of the bristles. The end of the rubber conical ring is fixed to the surface of the round block.

[0011] Preferably, the ends of the bristles are integrally formed with a bent portion, which faces the clamping portion.

[0012] Preferably, the protrusion has a first inclined surface at the end near the round block, and a second inclined surface at the end away from the round block, with the inclination angle of the first inclined surface being greater than that of the second inclined surface.

[0013] Preferably, an outer cover is fixed to the surface of the mounting plate. The outer cover is located outside the clamping member. A bracket is fixed to the end of the outer cover. A circular hole is opened in the middle of the bracket. The circular hole corresponds to the opening formed by multiple clamping parts. An inclined surface five is opened on the inner wall of the circular hole facing the clamping part. An arc-shaped protruding ring is fixed to the end of the inner wall of the circular hole away from the inclined surface five.

[0014] Preferably, a contact sensor is embedded on the surface of the bracket at the circular hole, and the contact sensor is electrically connected to electric push rod one and electric push rod two.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up a paint stripping mechanism, before paint stripping, the drive component drives multiple clamping parts to move away from each other. After the clamping parts move away from each other, the distance between the clamping blocks increases, making it easier for the inductor coil pin to be inserted between the clamping blocks, thus improving operational convenience. After the inductor coil pin is inserted between the clamping blocks, the drive component drives the clamping blocks to adhere to the pin. During this process, if the pin is bent, the clamping blocks can straighten the bent pin after adhering to the pin, facilitating the later use of the inductor coil. Subsequently, the heating wire can heat the paint surface at the pin. After heating for a period of time, the pin is pulled out from between the clamping blocks. During the pulling process, the protrusions can scrape off the heated and softened paint surface on the pin. During the scraping process, the protrusions will not damage the pin, thus protecting the pin. Moreover, after the paint surface is removed, there is no need to clean the pin, which takes less time. At the same time, during the heating process, the stress generated by the bending of the pin can be eliminated, so that the pin remains in a relatively straight state after being pulled out of the clamping blocks.

[0016] By setting up the cleaning components, after the paint stripping is completed, the clamping parts move away from each other. At this time, the electric push rod drives the round block to move towards the clamping part. When the brush bristles come into contact with the protrusion, the brush bristles can clean off the insulating paint stuck at the end of the protrusion, ensuring that the protrusion can stably scrape off the insulating paint when the paint stripping is done again.

[0017] By incorporating a bend, the brush bristles can accommodate more of the insulating varnish scraped off by the protrusions during the cleaning process, preventing the varnish from falling off the brush bristles and ensuring that the varnish can be cleaned out from inside the clamping block.

[0018] By setting up inclined plane one and inclined plane two, the inclined plane one has a larger tilt angle, which ensures both the guidance of the brush bristles and the effectiveness of the protrusion in scraping the paint surface. When the brush bristles are on the horizontal plane of the protrusion, the brush bristles are in a bent state. When the brush bristles leave the horizontal plane, they will spring back. Inclined plane two, with a smaller tilt angle, can prevent the brush bristles from springing back too much at once. If the brush bristles spring back too much at once, they will shake, and the insulating varnish cleaned off the brush bristles will fall back into the clamping block. Therefore, after setting up inclined plane two, the brush bristles adhere to inclined plane two and spring back slowly, preventing the insulating varnish from falling off the brush bristles and ensuring the cleaning effect of the insulating varnish.

[0019] By setting an outer cover, the internal structure can be protected from damage. The end of the outer cover is fixed with a bracket. During the paint removal process, the inductor coil is attached to the round hole of the bracket, which can prevent the operator's hands from coming into contact with the hot clamping part and prevent the operator from being burned, thus protecting the operator. Secondly, it can support the inductor coil and improve convenience. When the electric push rod drives the bristles to disengage from the clamping part, the bristles contact the convex ring in the round hole. At this time, the bent part of the bristles will hook on the surface of the convex ring, and the bristles will bend. When the bent part disengages from the convex ring, the bristles will quickly rebound and vibrate, thereby cleaning the insulating varnish inside the bristles without the need for subsequent manual cleaning, further improving the convenience of operation. When some insulating varnish falls from the side of the convex ring near the clamping part, the inclined surface five can guide the insulating varnish to slide down, preventing the insulating varnish from accumulating in the round hole. After the bristles are cleaned, the electric push rod two drives the round block and bristles to reset, preventing the round block and bristles from affecting the next pin paint removal.

[0020] By incorporating a rubber conical ring, when the bristles bend, the rubber conical ring can pull on the ends of the bristles to prevent them from bending excessively. When the bristles return to their original position, the pulling force of the rubber conical ring can assist the bristles in rebounding, increasing the durability of the bristles.

[0021] By setting a contact sensor, when the inductor coil is attached to the contact sensor, the first electric push rod is activated, and the clamping block can hold the pin without manual operation of the first electric push rod. When the inductor coil is detached from the contact sensor, the second electric push rod is activated, again without manual operation, thus improving the overall convenience of the paint removal process.

It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0026] like Figures 1-11 As shown, an embodiment of the present invention provides an inductor coil paint stripping device, including a control cabinet 1, and further comprising: Paint stripping mechanism 2 includes a mounting plate 3 fixed to the side of control cabinet 1. Multiple clamping members 4 are slidably connected to the surface of the mounting plate 3. These clamping members 4 are arranged in a circumferential array about the center of the mounting plate 3. Each clamping member 4 is slidably connected to an expansion portion 7 on the surface of the mounting plate 3. An inclined portion 6 is fixed to the end of the expansion portion 7, and a clamping portion 5 is fixed to the end of the inclined portion 6. A drive assembly 13 is provided at the inclined portion 6 to drive the multiple clamping members 4 to move closer or further apart. A clamping block 8 is fixed to the inner wall of the clamping portion 5. A guide block 38 is fixed to the end of the guide block 38, and the end of the guide block 38 has an arc-shaped guide surface. A heating wire 9 is fixed inside the clamping block 8, and multiple protrusions 10 are fixed on the surface of the clamping block 8. The control cabinet 1 provides power control and command transmission for the entire device, controlling the orderly operation of each component and ensuring the automation of the paint stripping process. The paint stripping mechanism 2 is used to complete the clamping, heating, and paint stripping operations of the inductor coil pins. The mounting plate 3 provides a mounting base for components such as the clamping parts 4 and the drive assembly 13, ensuring accurate positioning and stable operation of each component. Multiple clamping parts 4 arranged in a circumferential array are used to cooperate in clamping the inductor coil pins, ensuring uniform clamping force and avoiding uneven force deformation of the pins. The expansion part 7 is used to connect the mounting plate 3 and the tilting part 6, driving the tilting part 6 and the clamping part 10. The holding part 5 slides synchronously to open and close the clamping part 4; the tilting part 6 cooperates with the drive assembly 13 to convert the linear power of the drive assembly 13 into the opening and closing power of the clamping part 4; the clamping part 5 is used to fix the clamping block 8, which directly contacts the pin to achieve the clamping and positioning of the pin; the clamping block 8 directly adheres to the pin surface, transferring the heat of the heating wire 9, and at the same time providing a mounting carrier for the bump 10; the arc-shaped guiding surface of the guide block 38 is used to guide the inductor coil pin to be quickly and accurately inserted between the clamping blocks 8, avoiding pin misalignment; the heating wire 9 generates heat after being energized, heating the paint on the pin surface and softening it for subsequent scraping; the bump 10 is used to scrape off the softened paint. The paint surface is removed without damaging the pin body. During use, the device is started by the control cabinet 1, and the drive component 13 drives multiple clamping parts 4 to move away from each other, increasing the spacing between the clamping blocks 8. The inductor coil pin is inserted between the clamping blocks 8 along the arc-shaped guide surface of the guide block 38. Then, the drive component 13 drives the clamping parts 4 to move closer to each other, and the clamping blocks 8 fit the pin and correct the bent pin. The heating wire 9 is energized to heat and soften the paint surface. After heating, the inductor coil is pulled out, and the protrusion 10 scrapes off the softened paint surface, achieving rapid paint removal. At the same time, the heating process eliminates the bending stress of the pin, ensuring that the pin is straight. No cleaning is required after paint removal, improving work efficiency and protecting the pin from damage. like Figure 2 , Figure 4 and Figure 5As shown, in this embodiment, the drive assembly 13 includes multiple electric push rods 14 fixed on the mounting plate 3. The output ends of the multiple electric push rods 14 are jointly fixed to a drive ring 15. The inner wall of the drive ring 15 has a bevel 16. An inner ring 17 is provided inside the inclined portion 6. A bevel 18 is provided outside the inner ring 17. A support tube 19 is fixed to the end of the inner ring 17. The support tube 19 is fixed to the mounting plate 3. An outer pull member is provided outside the expansion portion 7. Before paint removal, the electric push rods 14 drive the drive ring 15. Ring 15 is close to clamping part 5. The outer pull member drives multiple expansion parts 7 to move away from each other, and the inclined part 6 moves away from inclined surface 4 18. When peeling paint, electric push rod 14 drives drive ring 15 away from clamping part 5. The inner side of inclined part 6 is attached to inclined surface 4 18. Electric push rod 14 provides power to drive assembly 13 and drives drive ring 15 to move through extension and retraction. Drive ring 15 is used to transmit the power of electric push rod 14. The inclined surface 3 16 on its inner wall cooperates with inclined part 6 to convert linear power into the opening and closing motion of clamping part 4. Force; the inclined plane 16, by squeezing the inclined part 6, drives the clamping parts 4 to move closer together; the inner ring 17 is fixed on the support tube 19, and its outer inclined plane 18 cooperates with the inclined part 6 to provide support and guidance for the inclined part 6, ensuring the clamping parts 4 open and close accurately; the support tube 19 is used to fix the inner ring 17 and also provides an installation base for the subsequent cleaning components; the outer pull member is used to drive the clamping parts 4 to move away from each other, realizing automatic opening. Before paint removal, the electric push rod 14 extends to drive the drive ring 15 to move closer to the clamping part 5, and the inclined plane 16... Sliding along the outside of the inclined part 6, the outer puller provides pulling force to drive multiple expansion parts 7 away from each other, the inclined part 6 disengages from the inclined surface 18, and the clamping parts 4 open to facilitate pin insertion; during paint removal, the electric push rod 14 retracts to drive the drive ring 15 away from the clamping part 5, the inclined surface 3 16 squeezes the inclined part 6, overcoming the pulling force of the outer puller, so that the inner side of the inclined part 6 fits against the inclined surface 18, multiple clamping parts 4 move closer to each other, and the clamping block 8 clamps the pin to achieve precise clamping, ensuring that the pin does not shift during heating and paint scraping, and improving the paint removal quality; The outer pull member includes multiple mounting seats 20 fixed to the surface of the mounting plate 3. Multiple guide sleeves 21 are fixed to the surface of the mounting seats 20. A tension spring 23 is fixed to the inner wall of each guide sleeve 21. A T-shaped guide rod 22 is fixed to the end of each tension spring 23. The end of the T-shaped guide rod 22 is movable from the guide sleeve 21 and fixed to the surface of the expansion portion 7. The mounting seats 20 are used to fix the guide sleeves 21, providing a mounting base for the outer pull member. The guide sleeves 21 guide the T-shaped guide rod 22, restricting its movement direction, and providing mounting space for the tension spring 23. The tension spring 23 provides elastic tension to drive the T-shaped guide rod 22 outward, thereby causing the clamping member 4 to open. The T-shaped guide rod 22 is connected to the tension spring. 23 and the expansion section 7 transmit the tension of the tension spring 23, causing the expansion section 7 and the clamping member 4 to slide. Before paint removal, the electric push rod 14 drives the drive ring 15 to approach the clamping section 5, the squeezing force of the inclined surface 3 16 on the inclined section 6 disappears, the tension spring 23 elastically rebounds, pulling the T-shaped guide rod 22 to slide outward along the guide sleeve 21. The T-shaped guide rod 22 drives the expansion sections 7 to move away from each other, and the clamping member 4 automatically opens. During paint removal, the electric push rod 14 drives the drive ring 15 to move away, the inclined surface 3 16 squeezes the inclined section 6, overcoming the tension of the tension spring 23, and causing the clamping member 4 to close. After paint removal is completed, the electric push rod 14 extends again, the tension spring 23 rebounds and causes the clamping member 4 to open, which is convenient for cleaning and the next loading.

[0027] like Figure 2 and Figure 3 As shown in this embodiment, the surface of the mounting plate 3 is provided with a plurality of grooves 36, and the inner wall of the grooves 36 is slidably connected to a slider 35. The end of the expansion portion 7 is fixed to the surface of the slider 35. The grooves 36 are provided on the surface of the mounting plate 3 to provide a sliding track for the slider 35 and limit the sliding direction of the slider 35.

[0028] like Figure 5 As shown in this embodiment, multiple round rods 24 are fixed to the surface of the mounting plate 3. All round rods 24 movably pass through the drive ring 15. A ring 25 is fixed to the ends of the multiple round rods 24. The round rods 24 are fixed to the surface of the mounting plate 3 to guide the drive ring 15, limit the direction of movement of the drive ring 15, and prevent the drive ring 15 from deviating or tilting when it moves. The ring 25 is fixed to the ends of the multiple round rods 24 to limit the travel of the drive ring 15, prevent the drive ring 15 from disengaging from the round rods 24, and fix the position of the round rods 24 to enhance the structural stability of the round rods 24.

[0029] like Figures 8-10As shown, in this embodiment, a cleaning assembly is provided on the inner wall of the support tube 19. The cleaning assembly includes an electric push rod 29 fixed to the inner wall of the support tube 19. A round block 30 is fixed to the end of the electric push rod 29, and multiple bristles 31 are fixed to the surface of the round block 30. When the clamping parts 5 move away from each other, the electric push rod 29 drives the bristles 31 to slide on the surface of the clamping block 8 and the protrusion 10 through the round block 30. A rubber conical ring 37 is fixedly sleeved on the surface of the bristles 31, and the end of the rubber conical ring 37 is fixed to the surface of the round block 30. The cleaning assembly is used to clean the residual insulating varnish on the surface of the clamping block 8 and the protrusion 10 after the paint stripping is completed, to ensure the effect of the next paint stripping. The electric push rod 29 is fixed to the inner wall of the support tube 19 to provide power to the cleaning assembly, and drives the round block 30 and the bristles 31 to move through the telescopic movement. The round block 30 is used to fix the bristles 31 and the rubber conical ring 37, transmit the power of the electric push rod 29, and drive the bristles 31 to move synchronously. The bristles 31 are used to directly scrape off the clamping block 8 and the protrusion 10. The insulating varnish on the surface of block 10 prevents varnish buildup from affecting subsequent varnish removal; the rubber conical ring 37 protects the bristles 31, preventing them from bending excessively, and also assists in the rebound of the bristles 31, enhancing their durability. After varnish removal, the clamping parts 5 move away from each other under the action of the drive assembly 13 and the external puller, reserving space for the cleaning assembly. The electric push rod 29 extends, pushing the round block 30 towards the clamping part 5. The round block 30 causes the bristles 31 and the rubber conical ring 37 to extend. The bristles 31 slide on the surfaces of the clamping block 8 and the protrusion 10, scraping away residual insulating varnish. After cleaning, the electric push rod 29 retracts, causing the round block 30, the bristles 31, and the rubber conical ring 37 to reset, avoiding affecting the next pin insertion and clamping. The rubber conical ring 37 provides pulling force when the bristles 31 bends, preventing the bristles 31 from breaking. During reset, it assists the bristles 31 in returning to their original shape, extending the service life of the bristles 31, ensuring that the surfaces of the clamping block 8 and the protrusion 10 are clean each time the varnish is removed, and improving the quality of varnish removal.

[0030] like Figure 9 As shown in this embodiment, the end of the brush bristles 31 is integrally formed with a bent portion 32, which faces the clamping portion 5. The bent portion 32 is integrally formed at the end of the brush bristles 31, facing the clamping portion 5. Its function is to enhance the capacity to hold the insulating varnish, ensuring that the insulating varnish can be effectively cleaned and carried out, and preventing the insulating varnish from falling back into the clamping block 8 during the cleaning process. When in use, the cleaning component is activated, and the brush bristles 31 move towards the clamping portion 5. The bent portion 32 first contacts the protrusion 10. Because it is bent towards the clamping portion 5, it can better fit the surface of the protrusion 10. At the same time, the groove formed by the bent portion 32 can hold more insulating varnish, firmly adhering the scraped insulating varnish to the brush bristles 31, preventing the insulating varnish from falling off the surface of the brush bristles 31 during the sliding process, ensuring that the insulating varnish can be smoothly carried out of the clamping block 8 area, improving the cleaning effect, reducing the trouble of secondary cleaning, and further improving the work efficiency.

[0031] like Figure 10As shown in this embodiment, the protrusion 10 has a first inclined surface 11 at the end near the round block 30, and a second inclined surface 12 at the end away from the round block 30. The inclination angle of the first inclined surface 11 is greater than that of the second inclined surface 12. The first inclined surface 11, located at the end of the protrusion 10 near the round block 30, has a larger inclination angle to guide the bristles 31 to slide smoothly onto the surface of the protrusion 10, while ensuring the effectiveness of the protrusion 10 in scraping away the paint. The second inclined surface 12, located at the end of the protrusion 10 away from the round block 30, has a smaller inclination angle to guide the bristles 31 to rebound slowly, preventing the insulating varnish from falling off. In use, the cleaning assembly is activated, and the bristles 31 move towards the clamping part. 5. Move the bent part 32 along the inclined surface 11. The large inclination angle of the inclined surface 11 makes it easy for the bristles 31 to quickly adhere to the surface of the protrusion 10. At the same time, the end structure of the protrusion 10 can ensure the scraping force on the softened paint surface during paint removal, ensuring thorough paint removal. After cleaning, the bristles 31 return to the direction of the support tube 19 and slide along the inclined surface 2 12. The small inclination angle of the inclined surface 2 12 guides the bristles 31 to slowly rebound, avoiding excessive rebound of the bristles 31 at one time, which would cause the insulating varnish in the bent part 32 to fall back into the clamping block 8. This ensures that the insulating varnish can be smoothly brought out, ensuring the cleaning effect, and at the same time, avoiding the accumulation of insulating varnish which would affect subsequent paint removal.

[0032] like Figure 2 As shown, in this embodiment, an outer cover 26 is fixed to the surface of the mounting plate 3. The outer cover 26 is located outside the clamping member 4. A bracket 27 is fixed to the end of the outer cover 26. A circular hole is opened in the middle of the bracket 27, which corresponds to the opening formed by multiple clamping parts 5. An inclined surface 33 is opened on the inner wall of the circular hole facing the clamping part 5. An arc-shaped protruding ring 34 is fixed to the end of the inner wall of the circular hole away from the inclined surface 33. The outer cover 26 is fixed to the surface of the mounting plate 3 and is located outside the clamping member 4. It is used to protect the internal clamping member 4, drive assembly 13 and other components, and prevent dust, debris from entering or damage to the components. 7 is fixed to the end of the outer cover 26 to support the inductor coil body and protect the operator from being burned by contact with the high-temperature clamping part 5; the round hole is opened in the middle of the bracket 27, corresponding to the opening of the clamping part 5, to avoid the inductor coil pins and facilitate the pin insertion into the clamping block 8; the inclined surface 533 is opened on the inner wall of the round hole near the clamping part 5 to guide the insulating varnish shaken off during the cleaning process to slide off and prevent the insulating varnish from accumulating in the round hole; the arc-shaped convex ring 34 is fixed on the inner wall of the round hole away from the inclined surface 533 to cooperate with the bending part 32 of the bristles 31 to realize the automatic cleaning of the bristles 31.

[0033] like Figure 11As shown in this embodiment, a contact sensor 28 is embedded on the surface of the bracket 27 at the circular hole. The contact sensor 28 is electrically connected to the electric push rod 14 and the electric push rod 29. When the inductor coil body is attached to the circular hole of the bracket 27, the inductor coil contacts the contact sensor 28. The contact sensor 28 sends a signal to the control cabinet 1, and the control cabinet 1 controls the electric push rod 14 to start, driving the clamping member 4 to close. The clamping block 8 clamps the pin, eliminating the need for manual activation of the electric push rod 14. After the paint is removed, the inductor coil is pulled outward, disengaging from the contact sensor 28. The contact sensor 28 sends a signal again, and the control cabinet 1 controls the electric push rod 14 to start, causing the clamping member 4 to open. At the same time, it controls the electric push rod 29 to start, activating the cleaning component for cleaning. The entire process requires no manual operation of the electric push rods 14 and 29, achieving automated linkage between paint removal and cleaning, reducing operation steps, and improving work efficiency.

[0034] Working principle: Before the paint stripping and loading, the electric push rod 14 starts and drives the drive ring 15 to move towards the clamping part 5. The inclined surface 16 of the inner wall of the drive ring 15 slides along the outside of the inclined part 6. The tension spring 23 of the outer pull member rebounds and drives the T-shaped guide rod 22 to move outward. The T-shaped guide rod 22 pulls the expansion part 7 away from each other along the slide groove 36. The inclined part 6 separates from the inclined surface 18 of the inner ring 17. Multiple clamping parts 5 open synchronously, and the distance between the clamping blocks 8 increases, which facilitates the insertion of the inductor coil pin. Insert the inductor coil pins into the gaps between the open clamping blocks 8 along the arc-shaped guide surface of the guide block 38. The inductor coil body is attached to the round hole of the bracket 27, triggering the contact sensor 28 on the bracket 27. The contact sensor 28 sends a signal to the control cabinet 1 to prepare to start the clamping action. After the contact sensor 28 is triggered, the electric push rod 14 drives the drive ring 15 to move away from the clamping part 5. The inclined surface 3 16 squeezes the inclined part 6, overcoming the tension of the tension spring 23 and driving the expansion part 7 to move closer to each other. The inner side of the inclined part 6 is in contact with the inclined surface 4 18 of the inner ring 17. The clamping part 5 drives the clamping block 8 to clamp the inductor coil pin, and the bent pin is corrected synchronously. Then the heating wire 9 is energized and heats up. The heat is transferred to the pin paint surface through the clamping block 8 and the protrusion 10, softening the paint surface and eliminating the bending stress of the pin. After heating is complete, pull the inductor coil outward, and the pin is pulled out from between the clamps 8. The protrusion 10 scrapes off the softened paint. After the inductor coil is separated from the bracket 27, it contacts the sensor 28 to trigger a cleaning command. At the same time, the electric push rod 14 once again drives the drive ring 15 to approach the clamping part 5, the outer puller pulls the expansion part 7 away from each other, and the clamping part 5 and the clamping block 8 open up to reserve space for cleaning operation; During cleaning, the electric push rod 29 is activated to push the round block 30 towards the clamping part 5. The round block 30 drives the bristles 31 and the rubber conical ring 37 to extend. The bent part 32 of the bristles 31 slides along the inclined surface 11, the horizontal surface and the inclined surface 12 of the protrusion 10 to scrape off and accommodate the insulating varnish on the surface of the clamping block 8 and the protrusion 10. The inclined surface 12 guides the bristles 31 to slowly rebound to prevent the insulating varnish from falling off. As the bristles 31 move outward, when they pass the arc-shaped protrusion 34 inside the round hole of the bracket 27, the bent part 32 is hooked and bent. After detaching from the arc-shaped protrusion 34, it quickly rebounds and shakes, shaking off the insulating varnish inside the bent part 32. The inclined surface 33 guides the shaken-off insulating varnish to slide down, avoiding accumulation. After cleaning, the electric push rod 29 drives the round block 30 and the bristles 31 to reset.
