Description

Technical Field

[0001] This utility model relates to the field of wire processing technology, specifically to a device for purging paint from the four edges and corners of a flat wire hair clip. Background Technology

[0002] Currently, the most common methods for removing paint from flat wires are mechanical rinsing and laser paint removal.

[0003] Laser coating removal advantages: High precision, removes coating without damaging the copper wire itself, ensuring conductivity and mechanical properties, and avoiding problems such as flattened wires and scratches. Disadvantages: High energy consumption, limited lifespan of key components requiring regular replacement, high operating and maintenance costs, and relatively lower efficiency compared to mechanical coating. Mechanical coating removal advantages: High efficiency, suitable for large-scale production, good coating removal consistency, ensuring consistent pressure parameters for each coating run, stable product quality, mature equipment structure for easy operation and maintenance, and lower initial investment and subsequent operating costs. Disadvantages: To ensure thorough coating removal during mechanical coating, it is unavoidable to remove a portion of the copper wire itself.

[0004] Currently, most copper wire manufacturers use a copper wire radius (R) of around R0.2-R0.5. Using existing mechanical varnishing equipment, it is necessary to remove a portion of the copper material to completely remove the varnish, especially at the four corners. The larger the radius, the greater the thickness that needs to be removed, which will result in copper waste, increase production costs, and may also have a certain impact on the electrical and mechanical properties of the copper wire. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a device for purging the paint from the four edges and corners of a flat hair clip, thus solving the problems mentioned in the background art.

[0006] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0007] A device for purging paint from the four edges and corners of a flat wire hair clip includes a base, a clamping and positioning block mounted on the base, and a purging knife mounted on the clamping and positioning block.

[0008] A gear power body is rotatably mounted on the base. A knife holder is mounted on the base inside the gear power body. A clamping and positioning block is slidably mounted on the base between the knife holders via a spring. A sliding bearing is mounted on the end of the clamping and positioning block away from the paint rinsing knife.

[0009] A servo motor is mounted on the base, and a transition gear is mounted on the output end of the servo motor. The servo motor is connected to the gear power body through the transition gear. A dust suction pipe is mounted on the base at the bottom end of the tool holder.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, a wire clamping cylinder is mounted on one side of the tool holder, which clamps and fixes the flat copper wire.

[0012] The beneficial effects of adopting the above-mentioned further solutions are:

[0013] The wire clamping cylinder provides stable and precise clamping force. During the painting process, the flat copper wire needs to remain absolutely stable to ensure that the painting knife accurately scrapes off the paint, preventing uneven paint removal or damage to the copper wire itself due to movement. The use of the wire clamping cylinder effectively ensures the flat copper wire is fixed in position during the painting process, improving the accuracy and quality of the painting process, ensuring product consistency, and also reducing additional wear and tear on equipment components caused by copper wire displacement, thus extending the equipment's service life.

[0014] Furthermore, the inner surface of the gear power body is a wavy curved surface. When the gear power body rotates, the wavy curved surface cooperates with the sliding bearing at the end of the clamping positioning block, thereby pushing the clamping positioning block to drive the paint scraping knife to contact the surface of the flat wire copper material, scraping off the surface paint of the central flat wire copper material.

[0015] The beneficial effects of adopting the above-mentioned further solutions are:

[0016] The wavy surface and sliding bearing design enable precise control over the contact force and position between the paint-removing blade and the flat copper wire. When the gear-driven unit rotates, different positions of the wavy surface contact the sliding bearing, smoothly and continuously pushing the clamping and positioning block to move, ensuring the paint-removing blade contacts the flat copper wire with the appropriate force and angle. This method not only effectively removes the paint but also minimizes wear on the copper wire itself, achieving a paint removal thickness close to that of laser paint removal. Simultaneously, it ensures uniform force on the paint-removing blade, extends its lifespan, reduces tool replacement costs, and improves production efficiency and product quality.

[0017] Furthermore, the suction pipe is connected to an external negative pressure dust collection device.

[0018] The beneficial effects of adopting the above-mentioned further solutions are:

[0019] Utilizing the negative pressure generated by an external negative pressure dust collection device, the suction pipe can collect paint debris generated during the painting process in a timely and efficient manner. If paint debris remains in the work area, it may re-adhere to the surface of the painted copper materials, affecting product quality, and may even enter critical components of the equipment, causing malfunctions. Connecting the suction pipe to the external negative pressure dust collection device maintains a clean working environment, reduces interference from paint debris during the painting process, ensures the smooth progress of the painting work, lowers equipment maintenance costs, and improves the stability of equipment operation.

[0020] Furthermore, the clamping positioning block and the paint-removing knife are arranged in a ring array around the flat copper wire.

[0021] The beneficial effects of adopting the above-mentioned further solutions are:

[0022] The circular array distribution ensures that all parts of the flat copper wire, especially the four corners, receive uniform coating treatment. For different locations on the flat copper wire, corresponding coating removal blades are used at appropriate angles and pressures to remove the coating, avoiding any blind spots. This distribution method guarantees consistent coating removal, improves product quality, and makes the entire coating process more efficient and comprehensive. It also allows for flexible adjustments based on different specifications of flat copper wire, enhancing the equipment's versatility.

[0023] This utility model provides a device for purging the paint from the four edges and corners of a flat wire hair clip. It has the following beneficial effects:

[0024] Traditional mechanical paint removal methods, to ensure thorough paint removal, especially at the rounded corners and four included corners of the copper wire, often require removing an additional portion of the copper material. The larger the rounded corner, the greater the thickness removed, resulting in copper waste. This new device, through its optimized structural design—the wavy curved surface inside the gear drive unit working in conjunction with the sliding bearing at the end of the clamping and positioning block—drives the clamping and positioning block to bring the paint removal blade into contact with the flat copper wire surface. This method allows for more precise control of the contact and degree of action between the paint removal blade and the copper material. This minimizes cutting of the copper material during paint removal, effectively reducing copper material loss. This not only saves on raw material costs but also reduces unnecessary resource waste.

[0025] Flat wires play a crucial role in the conduction of the stator. When the copper material's inherent losses decrease, the effective conductive cross-sectional area of ​​the flat wires relatively increases, leading to a decrease in resistance. According to electrical principles, reduced resistance decreases energy loss during current transmission, resulting in less heat generation and thus improving the stator's electrical performance. Simultaneously, due to lower copper material losses, the mechanical strength of the flat wires is better maintained. During stator operation, they can better withstand mechanical stress, reducing the risk of mechanical performance degradation caused by excessive copper material losses. This, in turn, improves the overall mechanical performance and stability of the stator, ultimately enhancing its comprehensive performance.

[0026] The structural design of this device makes the operation of the paint-washing blade more efficient. The clamping and positioning blocks and the paint-washing blades are arranged in a circular array around the flat copper wire, and the blades are driven by a gear-driven power unit in conjunction with a sliding bearing at the end of the clamping and positioning blocks. This method ensures more even force distribution on the paint-washing blades during operation, avoiding localized excessive stress. Compared to the uneven force distribution and rapid wear of blades that may occur with traditional mechanical paint-washing, this device effectively reduces blade wear, thereby extending blade life. It also reduces the frequency of blade replacement, lowers blade costs, and reduces downtime caused by blade replacement, thus improving production efficiency.

[0027] From an overall process perspective, this device, through innovative structural design and working principle, improves upon the shortcomings of traditional mechanical paint removal methods. During the paint removal process, precise control of the paint thickness and tool stress enhances the quality and efficiency of paint removal. Simultaneously, it reduces copper material and tool wear, thereby lowering raw material and tool costs. Furthermore, the more stable and efficient production process reduces product defect rates and increases production efficiency, thus optimizing the process. These optimizations bring significant economic benefits, including cost reduction and increased production efficiency, ultimately improving the overall profitability of the enterprise.

[0028] Laser coating removal offers advantages such as high precision and minimal damage to the copper wire itself, while allowing for excellent control over the coating thickness. This device, through its unique mechanical structure and operating method, excels in controlling the coating thickness, achieving results nearly identical to laser coating removal. This means the device has reached a high level of precision in coating removal, meeting the needs of production processes requiring high accuracy. It avoids quality problems caused by improper coating thickness control, ensuring product quality and performance, and demonstrating significant advantages over mechanical coating methods.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows:

[0038] Example 1

[0039] A device for removing paint from the four edges and corners of a flat wire hair clip includes a base 10, on which a clamping and positioning block 2 is mounted. A paint-removing blade 1 is mounted on the clamping and positioning block 2. The clamping and positioning block 2 and the paint-removing blade 1 are arranged in a circular array around the flat wire copper material. This circular array ensures that all parts of the flat wire copper material, especially the four edges and corners, receive uniform paint removal treatment. For different locations on the flat wire copper material, a corresponding paint-removing blade 1 can perform paint removal operations at an appropriate angle and force, avoiding paint removal dead zones. This distribution method ensures consistent paint removal, improves product quality, and makes the entire paint removal process more efficient and comprehensive. It also facilitates flexible adjustments for different specifications of flat wire copper material, enhancing the versatility of the equipment. A gear power body 5 is rotatably mounted on the base 10. A blade holder 6 is mounted on the base 10 inside the gear power body 5. A wire-clamping cylinder 3 is mounted on one side of the blade holder 6, clamping and fixing the flat wire copper material. The wire-clamping cylinder 3 provides a stable and precise clamping force. During the painting process, the flat copper wire needs to remain absolutely stable to ensure that the painting knife 1 accurately scrapes off the paint, avoiding uneven paint removal or damage to the copper wire itself due to copper wire movement. The use of the clamping cylinder 3 can effectively ensure the fixed position of the flat copper wire during the painting process, improve the accuracy and quality of painting, ensure product consistency, and also reduce the additional wear and tear on equipment components caused by copper wire displacement, extending the service life of the equipment. A clamping positioning block 2 is slidably installed on the base 10 between the knife holders 6 via a spring. A sliding bearing 4 is installed at the end of the clamping positioning block 2 opposite to the painting knife 1. The inner surface of the gear power body 5 is a wavy curved surface. When the gear power body 5 rotates, the wavy curved surface cooperates with the sliding bearing 4 at the end of the clamping positioning block 2, thereby pushing the clamping positioning block 2 to drive the painting knife 1 to contact the surface of the flat copper wire, scraping off the surface paint of the central flat copper wire. The cooperative design of the wavy curved surface and the sliding bearing 4 can achieve precise control of the contact force and position between the painting knife 1 and the flat copper wire. When the gear-driven body 5 rotates, different positions of the wavy curved surface contact the sliding bearing 4, smoothly and continuously pushing the clamping positioning block 2 to move, allowing the paint-removing knife 1 to contact the flat wire copper material with appropriate force and angle. This method not only effectively removes the paint but also minimizes wear on the copper material itself, achieving a paint removal thickness effect close to that of laser paint removal. Simultaneously, it ensures uniform force on the paint-removing knife 1, extends tool life, reduces tool replacement costs, and improves production efficiency and product quality.

[0040] Example 2

[0041] To maintain a clean working environment, reduce the interference of paint debris on the painting process, ensure the smooth progress of the painting work, and at the same time reduce equipment maintenance costs and improve equipment operational stability, for example, such as Figures 1 to 3As shown, this utility model also includes: a servo motor 7 mounted on the base 10, a transition gear 8 mounted on the output end of the servo motor 7, the servo motor 7 being connected to the gear power body 5 via the transition gear 8, and a suction pipe 9 mounted on the base 10 at the bottom end of the tool holder 6. The suction pipe 9 is connected to an external negative pressure dust collection device. Utilizing the negative pressure generated by the external negative pressure dust collection device, the suction pipe 9 can collect paint debris generated during the painting process in a timely and efficient manner. If paint debris remains in the working area, it may re-adhere to the surface of the painted copper material, affecting product quality, and may also enter key components of the equipment, causing equipment malfunction. The connection between the suction pipe 9 and the external negative pressure dust collection device can maintain a clean working environment, reduce the interference of paint debris on the painting process, ensure the smooth progress of the painting work, reduce equipment maintenance costs, and improve the stability of equipment operation.

[0042] Working principle:

[0043] The flat copper wire to be coated is placed in the designated position on the coating device. At this time, the clamping cylinder 3 is ready to clamp and fix the flat copper wire, ensuring its stable position during the coating process. The servo motor 7 is then turned on and begins operation. A transition gear 8 is installed at the output end of the servo motor 7, which is connected to the gear power body 5 for transmission. The principle of this transmission design is that the power output from the servo motor 7 is transmitted to the gear power body 5 through the transition gear 8, enabling the gear power body 5 to rotate at a set speed and direction, providing power for the subsequent coating action.

[0044] The gear power body 5 begins to rotate, and its inner surface is a wavy curved surface. As the gear power body 5 rotates, the wavy curved surface engages with the sliding bearing 4 at the end of the clamping and positioning block 2. The working principle is that when the protruding part of the wavy curved surface contacts the sliding bearing 4, it pushes the clamping and positioning block 2 towards the flat wire copper material. Since the clamping and positioning block 2 and the paint-applying knife 1 are arranged in a circular array around the flat wire copper material, the movement of the clamping and positioning block 2 drives the paint-applying knife 1 to approach and contact the surface of the flat wire copper material.

[0045] After the paint scraping knife 1 contacts the surface of the flat copper wire, it begins to scrape off the paint. At the same time, the suction pipe 9 located at the bottom of the knife holder 6 starts working. The suction pipe 9 is connected to an external negative pressure dust collection device. Using the principle of negative pressure, the paint chips and other impurities generated during the paint scraping process are sucked into the suction pipe 9 and collected into the external negative pressure dust collection device, maintaining a clean working environment and preventing paint chips from affecting the paint scraping process and product quality.

[0046] After the painting process is completed, the servo motor 7 stops running, and the gear power unit 5 also stops rotating. The wire clamping cylinder 3 releases its grip on the flat copper wire, allowing the operator to remove the painted flat copper wire. The entire painting device completes one work cycle and awaits the next task.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
