Description

Technical Field

[0001] The invention relates to a scraping line paint stripping device and a paint stripping method. Background Art

[0002] Enameled wire is a main type of winding wire, consisting of a conductor and an insulating layer. The bare wire is annealed and softened, then painted and baked several times. During use, the insulating paint on the end of the enameled wire must be completely removed before welding. Traditional manual paint scraping is slow and labor-intensive, and manual paint scraping often fails to be scraped clean, requiring repeated rework, resulting in low efficiency. Therefore, improvement is urgently needed. Summary of the invention

[0003] In order to improve the efficiency of paint scraping, the present invention provides a wire scraping and paint stripping device and a paint stripping method, which cooperate with an external clamp for clamping the enameled wire to perform mechanized wire scraping and paint stripping on the enameled wire.

[0004] The present invention provides a paint stripping device and paint stripping method using the following technical solutions:

[0005] A line scraping and paint stripping device, comprising

[0006] A wire scraping assembly, comprising a plurality of scraper columns and scraper blades, wherein the scraper blades are arranged at the ends of the scraper columns, the blade tips of the plurality of scraper blades are distributed around the same circumference, and the blade tips of the plurality of scraper blades surround to form a threading hole for the enameled wire to pass through; when the enameled wire is located in the threading hole, the enameled wire and the threading hole rotate relative to each other;

[0007] A limiting member, which limits the blade tips of the plurality of scraper blades to point to the same circumferential center;

[0008] Adjustment piece, adjusts the threading hole diameter.

[0009] The enameled wire clamped by the fixture is passed through the threading hole so that the enameled wire is passed between multiple scraper columns, the adjusting part is started, the diameter of the threading hole of the adjusting part is adjusted to adapt to the diameter of the enameled wire, the limiting part limits the direction of the tip of the scraper blade so that the tips of multiple scraper blades are all pressed against the outer peripheral wire paint of the enameled wire, the fixture is driven to rotate, thereby driving the enameled wire to rotate, and at the same time the fixture pulls the enameled wire outward so that the enameled wire rotates along its own circumference and moves along its own length direction in a direction away from the scraping assembly, multiple scraper blades cooperate to scrape the wire paint on the enameled wire along the circumference and length direction of the enameled wire, so that the wire paint on the enameled wire is completely scraped off, which is beneficial to saving manpower while ensuring the stability and efficiency of scraping off the wire paint.

[0010] Preferably, the scraper assembly includes a support frame, the limiting member includes a swing arm, the number of the swing arms is set corresponding to the number of scraper blades, the scraper blades are arranged at the ends of the swing arms, and the swing arms are rotatably connected to one end face of the support frame.

[0011] The swing arm rotates, driving the scraper blades at the ends of the swing arm to move away from or closer to each other, and the space between adjacent swing arms is used to drive the scraper blade to adjust the diameter of the threading hole. Compared with directly driving the scraper blade to slide radially along the threading hole, the scraper blade and the swing arm are not likely to slide out of the end of the support frame due to the small area of ​​the end of the support frame. This is beneficial to reducing the external area occupied by the scraper blade and the swing arm outside the support frame during movement, thereby reducing the situation where the swing arm protrudes from the support frame and causes damage.

[0012] Preferably, the limiting member also includes a plurality of limiting blocks and movable grooves, the number of the limiting blocks is set corresponding to the number of scraper blades, the scraper column is rotatably connected to the end of the swing arm, the scraper column and one end of the limiting block are relatively fixed, and a movable rod is provided at the end of the limiting block away from the scraper blade, the movable rod is inserted into the movable groove, and the movable groove is an arc groove, and the movable rod and the movable groove cooperate to drive the scraper column to rotate to offset the angle change caused by the revolution of the swing arm.

[0013] When the swing arm rotates, the scraper blade is driven to rotate together, forming a revolution state of the scraper blade. At this time, the scraper blade rotates with the swing arm, causing the blade tip to deviate from the center of the threading hole. Therefore, the scraper blade needs to rotate at a certain angle synchronously to keep the blade tip aligned with the center of the threading hole. When the swing arm rotates, the movable rod is driven to rotate by the limiting block. At the same time, since the relative position of the scraper blade and the movable groove changes, the movable rod slides synchronously in the movable groove. Due to the length limit of the limiting block and the groove shape limit of the movable groove, the scraper blade rotates. By limiting the groove shape of the movable groove, the rotation angle of the scraper blade offsets the angle of the scraper blade caused by the revolution of the swing arm, so that the blade tip of the scraper blade is always aligned with the center of the threading hole, so that the scraper blade maintains a stable scraping and paint stripping operation.

[0014] Preferably, the limiting block is arranged on a side of the swing arm away from the scraper blade, the side of the swing arm away from the scraper blade abuts against a side of the limiting block close to the scraper column, and the scraper column penetrates the swing arm and the limiting block.

[0015] The limiting block is arranged between the swing arm and the support frame, and the space between the swing arm and the support frame is utilized to reduce the area occupied by the swing arm and the limiting block on the end of the support frame, thereby reducing the area required for the support frame to be set. At the same time, the limiting block and the swing arm can directly apply force to the scraper blade, avoiding the need to set up a linkage structure that makes the overall scraper device structure complicated.

[0016] Preferably, the adjusting member comprises an adjusting cone, the adjusting cone is slidably connected to the support frame, the adjusting cone vertically penetrates the end surface of the support frame, and the plurality of limiting blocks are all in contact with the adjusting cone.

[0017] The adjusting cone is driven to slide along the support frame, so that the length of the adjusting cone protruding from the end face of the support frame changes. Since the limiting block abuts against the adjusting cone, the minimum distance that adjacent limiting blocks can approach each other is limited, thereby limiting the distance that multiple scraper blades can approach each other, thereby adjusting the diameter of the threading hole.

[0018] Preferably, the limiting member includes a synchronous belt, a plurality of internal gears and an elastic member, the plurality of internal gears are all internally engaged with the inner circumference of the synchronous belt, a rotating shaft is relatively fixedly provided at the end of the swing arm away from the scraper blade, the rotating shaft passes through the support frame and is coaxially fixed with the internal gear, the number of the internal gears is set corresponding to the number of scraper blades, and the elastic member pushes the plurality of scraper blades to move in a direction approaching each other.

[0019] When the length of the adjusting cone extending out of the surface of the support frame becomes longer, the limiting block is pushed by the adjusting cone, causing the swing arms to move in a direction away from each other, and the elastic member is compressed. When one of the internal gears is rotated under force, the synchronous belt meshing with it slides synchronously, thereby driving the remaining multiple internal gears to rotate, so that the multiple swing arms can stably maintain a synchronous rotation state, avoiding the situation where one of the swing arms is stuck and difficult to rotate, which is conducive to improving the compactness of the swing arm drive structure.

[0020] Preferably, the limiting member includes an external gear, multiple internal gears and an elastic member, the multiple internal gears are all internally meshed with the inner circumference of the external gear, a rotating shaft is relatively fixedly provided at the end of the swing arm away from the scraper blade, the rotating shaft passes through the support frame and is coaxially fixed with the internal gear, the number of the internal gears is set corresponding to the number of scraper blades, and the elastic member pushes the multiple scraper blades to move in a direction approaching each other.

[0021] When the length of the adjusting cone extending out of the surface of the support frame becomes longer, the limiting block is pushed by the adjusting cone, so that the swing arms move in a direction away from each other, and the elastic member is compressed. When one of the internal gears is rotated by force, the external gear meshing with it slides synchronously, thereby driving the remaining multiple internal gears to rotate, so that the multiple swing arms can stably maintain a synchronous rotation state, avoiding the situation where one of the swing arms is stuck and difficult to rotate, which is conducive to improving the compactness of the swing arm drive structure.

[0022] Preferably, the elastic member is configured as a tension spring, and both ends of the tension spring are connected to the end surface of the support frame and the swing arm respectively.

[0023] Preferably, the elastic member is configured as a torsion spring, and the torsion spring is sleeved on the rotating shaft of the swing arm.

[0027] S3: starting the driving motor to move the adjusting cone away from the scraper blade, and the elastic member applies pressure to the swing arm to make the multiple scraper blades approach each other, so that the blade tips of the scraper blades are pressed against the coating wire;

[0028] S4: Start the clamp so that the clamp drives the enameled wire to rotate and drives the enameled wire to move in a direction away from the wire scraping assembly, so that the wire paint of the enameled wire is scraped off.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-5 The present invention is described in further detail.

[0038] The embodiments of the present invention disclose a line scraping paint stripping device and a paint stripping method.

[0039] Reference Figure 1 as well as Figure 2 , a scraping line paint stripping device, comprising:

[0040] The scraper assembly 1 comprises three scraper columns 11 and scraper blades 12. The scraper blades 12 are arranged at the ends of the scraper columns 11. The blade tips of the three scraper blades 12 are evenly distributed around the same circumference. The blade tips of the three scraper blades 12 surround and form a threading hole for the enameled wire to pass through. When the enameled wire is located in the threading hole, the enameled wire and the threading hole rotate relative to each other.

[0041] The limiting member 2 limits the blade tips of the three scraping blades 12 to point to the same circumferential center;

[0042] Adjustment part 3, adjusts the diameter of the threading hole.

[0043] The enameled wire clamped by the fixture is passed through the threading hole so that the enameled wire is passed between the three scraper columns 11, and the adjusting member 3 is started. The diameter of the threading hole of the adjusting member 3 is adjusted to adapt to the diameter of the enameled wire. The limiting member 2 limits the direction of the tip of the scraper blade 12 so that the tips of the three scraper blades 12 are all pressed against the outer peripheral wire paint of the enameled wire, and the fixture is driven to rotate, thereby driving the enameled wire to rotate. At the same time, the fixture pulls the enameled wire outward, so that the enameled wire rotates along its own circumference and moves along its own length direction toward a direction away from the scraping assembly 1. The three scraper blades 12 cooperate to scrape off the wire paint on the enameled wire along the circumference and length direction of the enameled wire, so that the wire paint on the enameled wire is completely scraped off, which is beneficial to saving manpower while ensuring the stability and efficiency of scraping off the wire paint.

[0044] In this embodiment, the number of the scraper blades 12 is set to three. In other embodiments, the number of the scraper blades 12 can also be set to two, four, five, or six according to actual conditions.

[0045] The end of the scraper column 11 is provided with a groove 111 for the scraper blade 12 to be clamped and fixed. The groove 111 can prevent the scraper blade 12 from being misaligned with the scraper column 11 due to force, which is beneficial to improving the stability of the scraper blade 12 in scraping paint.

[0046] Reference Figure 3 as well as Figure 4 In this embodiment, the scraper assembly 1 includes a support frame 13, the limiting member 2 includes three swing arms 21, three limiting blocks 22 and three movable grooves 23, the swing arm 21 is rotatably connected to one end surface of the support frame 13, and the scraper column 11 passes through the end of the swing arm 21 and is rotatably connected to the end of the swing arm 21.

[0047] The limiting block 22 is arranged on the side of the swing arm 21 away from the scraper blade 12, and the side of the swing arm 21 away from the scraper blade 12 along its thickness direction abuts against the side of the limiting block 22 close to the scraper blade 12. The limiting block 22 is penetrated by an adjustment groove 221 and a plug hole 222, and the end of the scraper column 11 is inserted into the plug hole 222, and the plug hole 222 is connected with the adjustment groove 221. The plug hole 222 and the adjustment groove 221 are penetrated by the end face of the limiting block 22 close to the swing arm 21 in the direction away from the swing arm 21, and the length direction of the adjustment groove 221 is consistent with the length direction of the limiting block 22. The limiting block 22 is also penetrated by a threaded hole 223, and the threaded hole 223 is threadedly connected with a clamping screw, and the clamping screw penetrates the limiting block 22 to adjust the width of the adjustment groove 221, so that the scraper column 11 is clamped and fixed, and the relative rotation of the scraper column 11 and the limiting block 22 is limited.

[0048] The limiting block 22 is disposed between the swing arm 21 and the support frame 13, and the space between the swing arm 21 and the support frame 13 is utilized to reduce the area occupied by the swing arm 21 and the limiting block 22 at the end of the support frame 13, thereby reducing the area required for the support frame 13. At the same time, the limiting block 22 and the swing arm 21 can directly apply force to the scraper blade 12, avoiding the need to set a linkage structure that would complicate the structure of the overall scraping device.

[0049] The swing arm 21 rotates, driving the scraper blades 12 at the ends of the swing arm 21 to move away from or closer to each other, and utilizing the space between adjacent swing arms 21 to drive the scraper blades 12 to adjust the diameter of the threading hole. Compared with directly driving the scraper blades 12 to slide radially along the threading hole, the scraper blades 12 and the swing arm 21 are less likely to slide out of the end of the support frame 13 due to the small area of ​​the end of the support frame 13. This is beneficial for reducing the external area occupied by the scraper blades 12 and the swing arm 21 when they move, thereby reducing the situation where the swing arm 21 protrudes from the support frame 13 and causes damage.

[0050] A movable rod 24 is provided at one end of the limiting block 22 away from the scraper blade 12. The movable rod 24 is inserted into the movable groove 23. The movable groove 23 is an arc groove. The groove shape of the movable groove 23 is limited so that the rotation angle of the scraper blade 12 offsets the angle change of the scraper blade 12 caused by the revolution of the swing arm 21.

[0051] When the swing arm 21 rotates, the scraper blade 12 is driven to rotate together, forming a revolution state of the scraper blade 12. At this time, the scraper blade 12 rotates with the swing arm 21, so that the blade tip deviates from the center of the threading hole. Therefore, the scraper blade 12 needs to rotate at a certain angle synchronously to make the blade tip always aligned with the center of the threading hole. When the swing arm 21 rotates, the movable rod 24 is driven to rotate by the limiting block 22. At the same time, since the relative position of the scraper blade 12 and the movable groove 23 changes, the movable rod 24 slides synchronously in the movable groove 23. Due to the length limit of the limiting block 22 and the groove shape limit of the movable groove 23, the scraper blade 12 rotates, so that the blade tip of the scraper blade 12 is always aligned with the center of the threading hole, so that the scraper blade 12 maintains a stable scraping and paint stripping operation.

[0052] Reference Figure 3 as well as Figure 4 In this embodiment, the adjusting member 3 includes a driving motor 31 and an adjusting cone. The adjusting cone vertically penetrates the end surface of the support frame 13. The driving motor 31 drives the adjusting cone to slide along its own length direction, thereby adjusting the distance that the cone portion of the adjusting cone protrudes from the end surface of the support frame 13. The three limiting blocks 22 are all in contact with the adjusting cone.

[0053] The adjusting cone is driven to slide along the supporting frame 13, so that the length of the adjusting cone protruding from the end face of the supporting frame 13 changes. Since the limiting block 22 abuts against the adjusting cone, the minimum distance that adjacent limiting blocks 22 can approach each other is limited, thereby limiting the distance that the three scraper blades 12 can approach each other, thereby adjusting the diameter of the threading hole.

[0054] In this embodiment, the adjusting cone is a cone, and the support frame 13 is provided with a through hole 32 for the end of the adjusting cone to pass through.

[0055] In other embodiments, the adjustment cone may also be a triangular cone. When the adjustment cone is set as a polygonal cone, the number of cone surfaces of the cone is set corresponding to the number of scraper blades 12 , and each cone surface faces a scraper blade 12 .

[0056] Reference Figure 2 as well as Figure 3In this embodiment, the limiting member 2 includes a synchronous belt 25, three internal gears 26 and three elastic members. The three internal gears 26 are all internally meshed with the inner circumference of the synchronous belt 25. The end of the swing arm 21 away from the scraper blade 12 is relatively fixed with a rotating shaft. The rotating shaft passes through the support frame 13 and is coaxially fixed with the internal gear 26, so that the internal gear 26 drives the rotating shaft to rotate and then drives the swing arm to rotate. The elastic member pushes the three scrapers to move in a direction close to each other.

[0057] When the length of the adjusting cone extending out of the surface of the support frame 13 becomes longer, the limiting block 22 is pushed by the adjusting cone, so that the swing arms 21 move in a direction away from each other, and the elastic member is compressed. When one of the internal gears 26 is rotated by force, the synchronous belt 25 meshing with it rotates synchronously, thereby driving the remaining three internal gears 26 to rotate, so that the three swing arms 21 can stably maintain a synchronously rotating motion state, avoiding the situation where one of the swing arms 21 is stuck and difficult to rotate, which is conducive to improving the compactness of the driving structure of the swing arm 21.

[0058] Reference Figure 2 as well as Figure 5 In other embodiments, the limiting member 2 includes an external gear 27, three internal gears 26 and an elastic member. The three internal gears 26 are all internally meshed with the inner circumference of the external gear 27. The end of the swing arm 21 away from the scraper blade 12 is relatively fixed with a rotating shaft. The rotating shaft passes through the support frame 13 and is coaxially fixed with the internal gear 26. The elastic member pushes the three scrapers to move in a direction approaching each other, and the elastic member is always in a compressed state.

[0059] When the length of the adjusting cone extending out of the surface of the support frame 13 becomes longer, the limiting block 22 is pushed by the adjusting cone, so that the swing arms 21 move in a direction away from each other, and the elastic member is compressed. When one of the inner gears 26 is rotated by force, the outer gear 27 meshing with it slides synchronously, thereby driving the remaining three inner gears 26 to rotate, so that the three swing arms 21 can stably maintain a synchronously rotating motion state, avoiding the situation where one of the swing arms 21 is stuck and difficult to rotate, which is conducive to improving the compactness of the driving structure of the swing arm 21.

[0060] In this embodiment, the elastic member is configured as a tension spring, and both ends of the tension spring are connected to the end surface of the support frame 13 and the swing arm 21 respectively.

[0061] A paint stripping method comprising the following steps:

[0062] S1: Clamp the enameled wire on the fixture, and start the drive motor to move the scraper blades away from each other;

[0063] S2: Starting the fixture drives the enameled wire close to the wire scraping assembly so that the enameled wire passes through the wire threading hole;

[0064] S3: starting the driving motor to move the adjusting cone away from the scraper blade, and the elastic member applies pressure to the swing arm to make the multiple scraper blades approach each other, so that the blade tips of the scraper blades are pressed against the coating wire;

[0065] S4: Start the fixture, so that the fixture drives the enameled wire to rotate, and at the same time drives the enameled wire to move in a direction away from the wire scraping assembly, so that the wire paint of the enameled wire is scraped off

[0066] In other embodiments, the elastic member may also be configured as a torsion spring sleeved on the rotating shaft of the swing arm 21 .

[0067] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
