Description

Technical Field

[0001] The invention relates to the technical field of enameled copper wire processing equipment, in particular to a pretreatment equipment specially used for the surface of superfine diameter special enameled copper wire. Background Art

[0002] Enameled wire has good insulation performance, heat resistance and corrosion resistance. It is an insulated wire formed by one or more layers of insulating enamel wrapped around the copper wire. This insulated wire is widely used in various electrical equipment, such as motors, transformers, generators and various types of electronic equipment. Before the production of enameled wire, the surface of the copper wire needs to be cleaned, polished, activated, plated and other steps to improve the adhesion, conductivity, corrosion resistance and other properties of the insulating varnish to ensure the quality of the final enameled wire products.

[0003] The existing enameled copper wire surface treatment equipment will have the following problems during use:

[0004] When the copper wire is polished, polishing paste is usually applied to the surface of the copper wire, and then the surface is polished with polishing tools such as sandpaper. The sandpaper needs to be replaced due to wear and other reasons after long-term use. When replacing, the operator needs to stop the machine first, remove the polishing disc used to fix the sandpaper from the surface of the copper wire in turn, and then replace the polishing disc that needs to be replaced. After the replacement is completed, the copper wire is passed through the inside of the polishing disc where the sandpaper is set in sequence. After the polishing disc is replaced, it is properly adjusted to ensure the consistency of the concentricity and wire diameter of the polishing disc axis and the wire roller;

[0005] It can be seen that the existing polishing disc replacement method requires the polishing disc of the entire processing equipment to be disassembled before the polishing disc is replaced. The replacement process is cumbersome and the replacement cycle is long, which increases the difficulty of maintenance and replacement. At the same time, if an error occurs in the installation of one of the polishing discs during the cumbersome replacement process, such as the installation angle is too large or too small, or it is not in the center position, etc., in the subsequent use process, it will cause the copper wire to bend when passing through the polishing disc, and the polishing treatment will be uneven and incomplete, which will lead to the quality of the processed copper wire being reduced, affecting the quality of the enameled wire products finally produced, and increasing the workload of the operators;

[0006] At the same time, the process of replacing the polishing disc is cumbersome, and polishing discs of different mesh sizes cannot be replaced at any time according to polishing requirements during the entire processing process, which reduces the application scope of the equipment and cannot flexibly meet polishing processing requirements of various needs.

[0007] Therefore, the present invention proposes a pretreatment device specifically used for the surface of ultra-fine diameter special enameled copper wire to make up for and improve the deficiencies of the prior art. Summary of the invention

[0020] (III) Beneficial effects

[0021] The pretreatment equipment provided by the present invention is specially used for the surface of ultra-fine diameter special enameled copper wire, and has the following beneficial effects:

[0022] 1. The polishing disc is constructed by hingedly connecting two disc bodies. When replacing the polishing disc, only the polishing disc at the severely worn part needs to be disassembled and replaced. There is no need to disassemble all the polishing discs on the placement rack for replacement, which simplifies the replacement steps for operators and can complete the replacement work more quickly. It avoids the removal and reinstallation of the polishing disc of the entire equipment, reduces the error frequency of the polishing disc during installation, and improves the maintainability of the equipment. At the same time, there is no need to disassemble the polishing disc in the entire equipment to replace the polishing disc. The polishing disc is easily replaced, and polishing discs of different mesh sizes can be replaced at any time according to polishing needs during the production process, which can meet different copper wire polishing needs and increase the flexibility and adaptability of the production process.

[0023] 2. By making the mesh numbers of the sandpaper inside the two corresponding polishing discs at the front and back the same, and the mesh numbers of the sandpaper gradually increase as a whole, the equipment can perform step-by-step polishing on the enameled copper wire, and gradually polish and grind the rough parts of the copper wire surface to make it smooth, avoiding one-time excessive polishing that leads to uneven surface polishing, making the surface flatter and smoother. In addition, the mesh numbers of the sandpaper inside the two adjacent polishing discs are the same, so that the polishing discs have a certain redundancy, that is, when the sandpaper inside one of the polishing discs needs to be replaced for a long time, the other sandpaper can still continue the polishing work, maintaining the consistency of the polishing quality of the copper wire surface, and improving the stability of the equipment during operation.

[0024] 3. The symmetrically arranged cleaning rack can clean the surface of the copper wire before and after polishing to avoid scratches on the surface of the copper wire due to solid impurities on the surface during polishing. At the same time, a sliding rod is arranged on one side of the cleaning rack. When in use, the sliding rod presses the cleaning block downward to replace the cleaning block after a period of use. This can avoid the situation where the cleaning block has not been replaced for a long time and the cleaning effect is reduced due to poor cleaning power. It ensures that the cleaning block always has a good cleaning effect on the surface of the copper wire and improves the consistency of cleaning the copper wire sheath.

[0025] 4. Through the auxiliary rod connected to the inside of the second slide slot by sliding, when in use, the auxiliary rod pushes the wire tube to slide left and right on the outer surface of the auxiliary shaft, so that the polished copper wire can be more evenly wound on the outer surface of the wire tube, avoiding the copper wires from interlacing and entanglement, and reducing the subsequent processing work increased by the interlacing and entanglement of the copper wires. In addition, uniform winding can keep the copper wire in a stable tensile state, reduce the damage and uneven deformation that may occur to the copper wire during the winding process, and avoiding the interlacing and entanglement of the copper wire can also reduce the risk of wear and scratches on the wire surface.

When in use, the equipment can perform a step-by-step polishing process on the enameled copper wire, and gradually polish and grind the rough parts of the copper wire surface to smooth it, avoiding one-time excessive polishing that leads to uneven surface polishing, making its surface flatter and smoother. In addition, the mesh number of the sandpaper inside the two adjacent polishing discs 5 is the same, so that the polishing disc 5 has a certain redundancy, that is, when the sandpaper inside one of the polishing discs 5 needs to be replaced due to a long time, the other sandpaper can still continue the polishing work, thereby maintaining the consistency of the polishing quality of the copper wire surface and improving the stability of the equipment during operation.

[0043] The interior of the storage box 2 is fixedly connected with a delivery pipe 7, and two delivery pipes 7 are arranged. The top ends of the delivery pipes 7 pass through the storage box 2 and extend to the top of the storage box 2. The outer surfaces of the delivery pipes 7 extending to the top of the storage box 2 are connected with spray pipes 8. The two spray pipes 8 are respectively located on the same vertical section with the two wire rollers 6, so that the polishing paste sprayed through the spray holes opened on the surface of the spray pipes 8 can be accurately sprayed onto the surface of the copper wire to be processed. The spray pipes 8 are evenly provided with spray holes on one side close to the wire roller 6. The polishing paste inside the storage box 2 is transported to the inside of the spray pipes 8 through the delivery pipes 7, and then sprayed onto the surface of the copper wire wound on the surface of the wire roller 6 through the spray holes opened on the surface of the spray pipes 8.

[0044] A cleaning frame 9 is fixedly connected to the upper surface of the fixed frame 1 and near the rotating wheel 3. The cleaning frame 9 is symmetrically arranged with the vertical center line of the placement frame 4 as a reference, so that the copper wire can be cleaned before and after the polishing process to avoid scratches on the surface of the copper wire during the polishing process due to solid impurities on the surface;

[0047] An auxiliary shaft 21 is rotatably connected to the surface of one side of the fixed frame 1 close to the cleaning frame 9. The auxiliary shaft 21 penetrates the fixed frame 1 and extends to the side of the fixed frame 1 away from the cleaning frame 9. The outer surface of the auxiliary shaft 21 and the outer surface of the motor output shaft are fixedly connected to a second rotating wheel 22. The outer surface of the second rotating wheel 22 is transmission-connected with a second belt 23. The outer surface of the auxiliary shaft 21 is slidably connected to a wire tube 24. A clip is provided on the inner side of the wire tube 24 to fix one end of the copper wire on the surface of the wire tube 24. The vertical section of the sliding connection between the auxiliary shaft 21 and the wire tube 24 is in the shape of a "convex" character, so that the wire tube 24 can rotate with the auxiliary shaft 21. Under the action of the auxiliary rod 27, the wire tube 24 can slide left and right on the surface of the auxiliary shaft 21, so that the polished copper wire can be evenly wound around the surface of the wire tube 24.

[0048] The auxiliary shaft 21 passes through the fixed frame 1, and the auxiliary shaft 21 extends to the end away from the cleaning frame 9 and is fixedly connected to the rotating shaft 25. The outer surface of the rotating shaft 25 is provided with a second slide groove 26, and the inside of the second slide groove 26 is slidably connected with an auxiliary rod 27. The end of the auxiliary rod 27 away from the second slide groove 26 passes through the fixed frame 1, and the auxiliary rod 27 extends to the side of the fixed frame 1 close to the cleaning frame 9. The outer surface of the wire tube 24 close to the fixed frame 1 is provided with a third slide groove 28. The auxiliary rod 27 extends to the end of the fixed frame 1 close to the cleaning frame 9 and is slidably connected to the inside of the third slide groove 28.

[0049] The second slide groove 26 is composed of two sections of thread-shaped grooves with opposite rotation directions and interlaced with each other, and the two ends of the two sections of the thread-shaped grooves are connected with each other.

[0050] The following is the entire working process and working principle of the above embodiment:

[0051] Before use, the operator places the copper wire to be processed on the surface of the rotating wheel 3, and then passes one end of the copper wire through the cleaning block 13 inside the cleaning frame 9 near the rotating wheel 3, and then wraps around the wire roller 6 to pull it to the polishing disk 5, and passes the copper wire through the polishing disk 5 in sequence through the guide groove opened on the surface of the placement frame 4, and then passes the end that passes through the polishing disk 5 through the cleaning block 13 inside the cleaning frame 9 near the auxiliary shaft 21 and connects it to the clip on the inside of the wire tube 24, and finally starts the equipment to polish the copper wire.

[0052] When in use, first, the operator turns on the switch of the motor, and the output shaft end of the motor drives the second rotating wheel 22 fixedly connected to the surface of the motor output shaft to rotate. When the second rotating wheel 22 on the surface of the motor output shaft rotates, the second rotating wheel 22 fixedly connected to the auxiliary shaft 21 is driven to rotate through the second belt 23 connected to the second rotating wheel 22. When the second rotating wheel 22 fixedly connected to the auxiliary shaft 21 rotates, it drives the auxiliary shaft 21 to rotate. When the auxiliary shaft 21 rotates, it drives the wire tube 24 slidably connected to the surface to rotate. When the wire tube 24 rotates, the copper wire is passed through the polishing disc 5 by pulling force, and the sandpaper set inside the polishing disc 5 polishes its surface;

[0053] Furthermore, before the copper wire passes through the polishing disc 5, the polishing paste in the storage box 2 is transported to the inside of the spraying tube 8 via the transporting tube 7, and then the polishing paste transported to the inside of the spraying tube 8 is sprayed to the surface of the copper wire to be processed on the surface of the wire roller 6 through the spraying holes opened on the surface of the spraying tube 8. The abrasive particles contained in the polishing paste can help shape the copper wire during the polishing process and provide sufficient lubrication to prevent excessive wear of the surface.

[0054] Furthermore, when the polishing disc 5 needs to be replaced due to wear and other reasons during long-term use, the operator first pushes up the baffle 502 which is slidably connected to the disc body 501 to be replaced, and then presses the end of the sliding column 506 extending to the outside of the disc body 501 to move in the direction away from the baffle 502. After the sliding column 506 moves in the direction away from the baffle 502, it drives the auxiliary ring 507 which is slidably connected on the surface to move in the direction away from the baffle 502. When the auxiliary ring 507 moves in the direction away from the baffle 502, since the side of the stop block 505 close to the auxiliary ring 507 is set as an inclined surface, when the sliding column 506 is pressed, the sliding column 506 drives the auxiliary ring 507 to The auxiliary ring 507 moves in the direction away from the baffle 502, and at the same time, the auxiliary ring 507 squeezes the stopper 505 to move downward, so that the auxiliary ring 507 can move to the side of the stopper 505 away from the baffle 502, and the side of the auxiliary ring 507 without the inclined surface is in contact with the sliding column 506, and because the surface of the side of the auxiliary ring 507 close to the baffle 502 is set as an inclined surface, therefore, when the operator moves the sliding column 506 in the direction close to the baffle 502, the inclined surface of the auxiliary ring 507 squeezes the stopper 505 downward, so that the sliding column 506 is taken out from the inside of the slide groove 1 503, and then the two disc bodies 501 are rotated in the opposite direction with the hinge point as the axis and then taken away, and then a new polishing disc 5 is replaced to this position;

[0055] Through the above structure, when replacing the polishing disc 5, it is only necessary to disassemble and replace the polishing disc 5 at the severely worn part, and there is no need to disassemble and replace all the polishing discs 5 on the placement rack 4, which simplifies the replacement steps for the operator, and can complete the replacement work more quickly, avoiding the disassembly and reinstallation of the polishing disc 5 of the entire equipment, reducing the error frequency of the polishing disc 5 during installation, and improving the maintainability of the equipment. At the same time, there is no need to disassemble the polishing disc 5 in the entire equipment to replace the polishing disc 5. Through the convenient replacement of the polishing disc, the polishing disc 5 of different mesh sizes can be replaced at any time according to the polishing needs during the production process, which can meet the polishing needs of different copper wires and increase the flexibility and adaptability of the production process.

[0056] Next, when the copper wire passes through the cleaning rack 9 near the rotating wheel 3 under the action of the pulling force of the wire tube 24, the cleaning block 13 inside the cleaning rack 9 near the rotating wheel 3 preliminarily cleans the solid impurities, dust and the like on the surface of the copper wire to avoid scratches on the surface of the copper wire during the polishing process due to the solid impurities on the surface. After that, when the copper wire polished by the sandpaper inside the polishing disk 5 passes through the cleaning rack 9 near the auxiliary shaft 21, the cleaning block 13 inside the cleaning rack 9 near the auxiliary shaft 21 cleans away the polishing paste remaining on the surface of the copper wire after the polishing process and the solid particles generated during the polishing process, so that the surface of the copper wire after the final polishing process remains clean;

[0057] Furthermore, after the cleaning block 13 inside the cleaning rack 9 has been used for a period of time, the output shaft end of the motor drives the rotating wheel 16 fixedly connected to the surface of the motor output shaft to rotate. When the rotating wheel 16 on the surface of the motor output shaft rotates, the belt 17 connected to the rotating wheel 16 drives the rotating wheel 16 fixedly connected to the turntable 15 through the cylinder to rotate. When the rotating wheel 16 fixedly connected to the turntable 15 rotates, the meshing teeth fixedly connected to the surface of the turntable 15 drive the gear 18 meshing therewith to rotate intermittently. When the gear 18 rotates, it drives the push rod 19 coaxially fixedly connected to the gear 18 to rotate. Since the push rod 19 is slidably connected to the slide groove opened on one side of the slide rod 20, the push rod 19 pushes the sliding connection in the cleaning The slide bar 20 on one side of the cleaning rack 9 moves up and down. During the movement of the slide bar 20, the extrusion block fixedly connected to the slide bar 20 is driven to move. When the extrusion block fixedly connected to the slide bar 20 moves downward, it squeezes the used cleaning block 13 below through the unused cleaning block 13 above to move downward. When the unused cleaning block 13 above drives the used cleaning block 13 below to move downward, it drives the card slot 14 opened on one side of the used cleaning block 13 below to move downward. At this time, the card block 12 here and the card slot 14 opened on one side of the cleaning block 13 are no longer located on the same horizontal section, so the card block 12 is no longer connected to the inside of the card slot 14 opened on one side of the cleaning block 13. At this time, the used cleaning block 13 located at the bottom falls from the inside of the cleaning rack 9;

[0058] When the unused cleaning block 13 at the top moves downward to the same position as the copper wire height, the used cleaning block 13 at the bottom is replaced. At this time, the card block 12 at the same position as the copper wire height is carded into the card slot 14 opened on one side of the unused cleaning block 13, and the unused cleaning block 13 is fixed here to clean the surface of the copper wire. By replacing the cleaning block 13 after using it for a period of time, it can avoid the situation where the cleaning block 13 is not replaced for a long time, resulting in a decrease in cleaning effect due to poor cleaning power, thereby ensuring that the cleaning block 13 always has a good cleaning effect on the surface of the copper wire and improving the consistency of cleaning the copper wire sheath.

[0059] Finally, when the auxiliary shaft 21 rotates, it drives the rotating shaft 25 fixedly connected to the auxiliary shaft 21 to rotate. When the rotating shaft 25 rotates, it drives the second slide groove 26 opened on the surface to rotate. When the second slide groove 26 rotates, it pushes the auxiliary rod 27 slidably connected inside the second slide groove 26 to move left and right. When the auxiliary rod 27 moves, it pushes the wire tube 24 to move left and right. Since the vertical section of the sliding connection between the auxiliary shaft 21 and the wire tube 24 is a "convex" shape, the auxiliary shaft 21 drives the wire tube 24 to rotate at the same time, under the action of the auxiliary rod 27, The wire tube 24 will also slide left and right on the surface of the auxiliary shaft 21, so that the copper wire cleaned by the cleaning block 13 inside the cleaning frame 9 near the auxiliary shaft 21 can be evenly wound on the outer surface of the wire tube 24, avoiding the copper wires from interlacing and entanglement with each other, and reducing the subsequent processing work increased by the interlacing and entanglement of the copper wires. In addition, uniform winding can keep the copper wire in a stable tensile state, reduce the damage and uneven deformation that may occur to the copper wire during the winding process, and avoiding the interlacing and entanglement of the copper wires can also reduce the risk of wear and scratches on the wire surface.
