Description

Technical Field

[0001] This invention relates to the field of copper wire processing technology, specifically to an automated winding and paint scraping device for an automotive air conditioning electromagnetic clutch. Background Technology

[0002] Copper wire is widely used in the field of new energy vehicle motors, and removing the enamel coating from the copper wire surface is a key process in the manufacturing process. Its main purpose is to remove the insulating enamel layer on the surface of the copper wire, thereby achieving an effective connection between the conductors. The quality of the connection is not only directly related to the electrical performance of the motor, but also closely related to its mechanical properties.

[0003] An invention with application publication number CN119171704A discloses a high-precision paint scraping device and its scraping method, including a positioning mechanism, a blade holder, and a driving mechanism. A paint scraper is fixed on the blade holder. The driving mechanism includes a first driving mechanism and a second driving mechanism. The first driving mechanism includes a first electric cylinder and a first connecting block. The blade holder is fixed on the first connecting block, and the two move axially synchronously to limit the scraping length of the paint scraper. The second driving mechanism includes a second electric cylinder and a second connecting block. One side of the second connecting block is slidably connected to the first connecting block, and the two move axially respectively. At the same time, the other side of the second connecting block is slidably attached to a guide inclined surface, so that while the second connecting block moves axially relative to the first connecting block, it drives the first connecting block to move radially relative to the paint removal end, thereby limiting the scraping depth of the paint scraper.

[0004] However, the inventors discovered that in the actual production process of copper wire, it is often necessary to first wind it into a coil using a winding machine, then manually cut it, remove the coil, place the end on a paint scraping machine for paint scraping, and then carry out subsequent packaging work. This is not only time-consuming and labor-intensive, but also involves complicated procedures. Based on this, we proposed an automated winding and paint scraping device for automotive air conditioning electromagnetic clutches. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by setting a grinding chamber in the middle of the winding machine. The grinding chamber contains a drive assembly, a cutting assembly, a grinding assembly, a linkage assembly, and a correction assembly arranged sequentially. This invention uses a drive motor to drive the grinding roller to revolve. Through the meshing of a small gear below the grinding roller and a first gear ring, the grinding roller rotates on its own axis, thus grinding the paint surface on the copper wire while simultaneously revolving around the central axis. At the same time, the drive motor drives a lead screw to rotate, causing a square block to move on the lead screw, which in turn moves a piston rod inside an air cylinder. This causes the piston rod to move a blade towards the copper wire, cutting the copper wire as the grinding roller revolves around it. This invention achieves the grinding and cutting of copper wire through automated machinery, reducing manual labor time, ensuring product quality, and improving production efficiency.

[0006] To address the aforementioned technical problems, the present invention adopts the following technical solution:

[0007] An automated winding and painting device for an automotive air conditioning electromagnetic clutch includes a winding machine and guide wheels and winding wheels at both ends of the winding machine for transmitting copper wires. A grinding chamber is provided in the middle of the winding machine, and a fixed plate is provided in the middle of the grinding chamber. A grinding component for painting the outer surface of the copper wires is provided on the fixed plate. A correction component that rotates in the opposite direction to the grinding component is provided on the lower end face of the fixed plate. A linkage component is provided between the grinding component and the correction component. A drive component is provided on one side of the grinding component, and a cutting component is provided at the upper end of the grinding component. While the grinding component is painting the copper wires, the drive component simultaneously drives the cutting component to cut the copper wires.

[0008] As a preferred embodiment, the grinding assembly includes a first lower base plate rotatably mounted on a fixed plate, a grinding roller rotatably mounted on the first lower base plate, a first upper base plate mounted above the grinding roller, a pinion mounted at the lower end of the grinding roller, and a first gear ring fixedly mounted on the fixed plate and meshing with the pinion.

[0009] As a preferred embodiment, a rotating roller is fixedly provided on the lower end face of the first lower base plate, the rotating roller passes through the fixed plate, and a first gear is provided at the lower end of the rotating roller.

[0010] As a preferred embodiment, the linkage assembly includes a column at the lower end of the fixed plate, a second gear mounted on the column, and a second gear ring mounted on the outer ring of the first gear and meshing with the second gear.

[0011] As a preferred embodiment, the correction assembly includes a second upper base plate fixedly connected to the second gear ring, a second lower base plate rotatably disposed at the bottom of the grinding chamber, and a correction roller disposed between the second upper base plate and the second lower base plate.

[0012] As a preferred embodiment, the cutting assembly includes a limiting post disposed on the inner side of the first upper base plate, a rectangular slide groove disposed on the lower surface of the limiting post, a cylindrical slide groove connected to the rectangular slide groove, a blade slidably disposed in the rectangular slide groove, a piston rod disposed at the rear end of the blade and sliding in the cylindrical slide groove, a rotating sleeve rotatably disposed on the limiting post, an arc-shaped groove disposed inside the rotating sleeve, an air cylinder disposed on the rotating sleeve, a lead screw fixedly disposed on the top surface of the grinding chamber, a square block disposed on the lead screw, and a piston rod disposed on the square block and slidably disposed in the air cylinder.

[0013] As a preferred embodiment, the cylindrical groove is connected to the arc-shaped groove, and the air cylinder is connected to the arc-shaped groove.

[0014] As a preferred embodiment, the drive assembly includes a drive motor fixedly disposed inside the grinding chamber, a third gear disposed at the upper end of the drive motor, a third gear ring disposed on the outer side of the first upper base plate, a first conical tooth disposed on the output shaft of the drive motor, a limiting block fixedly disposed on the top surface of the grinding chamber, a rotating shaft rotatably disposed within the limiting block, a second conical tooth disposed on the rotating shaft, and a belt disposed between the other end of the rotating shaft and the lead screw.

[0015] As another preferred embodiment, the outer surface of the correction roller is covered with a layer of fabric.

[0016] The beneficial effects of this invention are:

[0017] In this invention, a driving motor drives the grinding roller to revolve, and the meshing of the small gear below the grinding roller and the first gear ring drives the grinding roller to rotate. This allows the grinding roller to rotate on its own axis while revolving around the central axis, thus polishing the paint surface on the copper wire, making the paint surface on the outer surface of the copper wire polished more evenly and quickly.

[0018] In this invention, a drive motor drives a lead screw to rotate, and a square block moves on the lead screw, which in turn moves a piston rod inside an air cylinder. This causes the piston rod to move a blade toward the copper wire. As the blade revolves with the grinding roller, it cuts the copper wire. This invention achieves the grinding and cutting of copper wire through automated machinery, reducing manual labor time, ensuring product quality, and improving production efficiency.

[0019] The present invention includes a correction component that rotates in the opposite direction to the grinding component. While the grinding roller revolves, it drives the copper wire to twist in one direction, and the correction component that rotates in the opposite direction can balance the twisting force of the copper wire.

[0020] In summary, this equipment has advantages such as high automation, good surface paint removal effect, and high production efficiency, and is especially suitable for the field of copper wire processing technology. Attached Figure Description

Detailed Implementation

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figures 1 to 8As shown, an automated winding and painting device for an automotive air conditioning electromagnetic clutch includes a winding machine 1 and guide wheels 2 and winding wheels 3 disposed at both ends of the winding machine 1 for transmitting copper wires. A grinding chamber 4 is disposed in the middle of the winding machine 1, and a fixing plate 5 is disposed in the middle of the grinding chamber 4. A grinding component 6 for painting the outer surface of the copper wires is disposed on the fixing plate 5. A correction component 7 that rotates in the opposite direction to the grinding component 6 is disposed on the lower end face of the fixing plate 5. A linkage component 8 is disposed between the grinding component 6 and the correction component 7. A drive component 9 is disposed on one side of the grinding component 6, and a cutting component 10 is disposed on the upper end of the grinding component 6. While the grinding component 6 is painting the copper wires, the drive component 9 synchronously drives the cutting component 10 to cut the copper wires.

[0034] It is worth mentioning here that, as Figure 4 As shown, the polishing assembly 6 includes a first lower base plate 61 rotatably mounted on a fixed plate 5, a polishing roller 62 rotatably mounted on the first lower base plate 61, a first upper base plate 63 mounted above the polishing roller 62, a small gear 64 mounted at the lower end of the polishing roller 62, and a first gear ring 66 fixedly mounted on the fixed plate 5 and meshing with the small gear 64. In this invention, the first lower base plate 61 and the first upper base plate 63 drive the polishing roller 62 to revolve. Through the meshing of the small gear 64 and the first gear ring 66, the polishing roller 62 rotates on its own axis while revolving, polishing the paint surface on the copper wire, making the paint surface on the outer surface of the copper wire polished more evenly and quickly.

[0035] In this embodiment, if Figure 4 As shown, a rotating roller 67 is fixedly installed on the lower end face of the first lower base plate 61. The rotating roller 67 passes through the fixed plate 5, and a first gear 68 is provided at the lower end of the rotating roller 67. The present invention drives the rotating roller 67 and the first gear 68 to rotate by rotating the first lower base plate 61, thereby driving the correction component 7 below to rotate.

[0036] In addition, such as Figure 5 As shown, the linkage component 8 includes a column 81 at the lower end of the fixed plate 5, a second gear 82 mounted on the column 81, and a second gear ring 83 mounted on the outer ring of the first gear 68 and meshing with the second gear 82; the first gear 68 rotates to drive the second gear 82 to rotate, and the second gear 82 then drives the second gear ring 83 to rotate in the opposite direction.

[0037] Furthermore, such as Figure 5As shown, the correction component 7 includes a second upper base plate 71 fixedly connected to the second gear ring 83, a second lower base plate 72 rotatably disposed at the bottom of the grinding chamber 4, and a correction roller 73 disposed between the second upper base plate 71 and the second lower base plate 72; the outer surface of the correction roller 73 is covered with a layer of cloth; in this invention, a correction component 7 that rotates in the opposite direction to the grinding component 6 is provided. While the grinding roller 62 revolves, it drives the copper wire to twist in one direction, and the correction component 7 that rotates in the opposite direction can balance the twisting force of the copper wire. The outer side of the correction roller 73 is covered with cloth, and the friction of the cloth is small, so it will not cause wear to the surface of the copper wire.

[0038] It needs to be emphasized that, such as Figures 6 to 8 As shown, the cutting assembly 10 includes a limiting post 101 disposed inside the first upper base plate 63, a rectangular slide groove 102 disposed on the lower surface of the limiting post 101, a cylindrical slide groove 103 communicating with the rectangular slide groove 102, a blade 104 slidably disposed in the rectangular slide groove 102, a piston post 105 disposed at the rear end of the blade 104 and sliding in the cylindrical slide groove 103, a rotating sleeve 106 rotatably disposed on the limiting post 101, an arc groove 107 disposed inside the rotating sleeve 106, an air cylinder 108 disposed on the rotating sleeve 106, and a lead screw 109 fixedly disposed on the top surface of the grinding chamber 4. A square block 1010 placed on a lead screw 109 and a piston rod 1011 placed on the square block 1010 and slidably disposed in an air cylinder 108 are driven by a drive motor 91 to rotate the lead screw 109. The square block moves on the lead screw 109, causing the piston rod 1011 to move within the air cylinder 108. This causes the piston rod 105 to move the blade 104 toward the copper wire. The blade cuts the copper wire while revolving with the grinding roller 62. This invention achieves the grinding and cutting of copper wire through automated machinery, reducing manual labor time, ensuring product quality, and improving production efficiency.

[0039] In this embodiment, as Figures 6 to 8 As shown, the cylindrical groove 103 is connected to the arc groove 107, and the air cylinder 108 is connected to the arc groove 107. The piston rod 1011 moves in the air cylinder 108, which increases the air pressure in the air cylinder 108 and the cylindrical groove 103, driving the piston rod 105 to move the blade 104 forward to cut the copper wire.

[0040] It is worth mentioning here that, as Figures 6 to 8As shown, the drive assembly 9 includes a drive motor 91 fixedly installed inside the grinding chamber 4, a third gear 92 installed at the upper end of the drive motor 91, a third gear ring 93 installed on the outer side of the first upper base plate 63, a first conical tooth 94 installed on the output shaft of the drive motor 91, a limiting block 95 fixedly installed on the top surface of the grinding chamber 4, a rotating shaft 96 rotatably installed inside the limiting block 95, a second conical tooth 97 installed on the rotating shaft 96, and a belt 98 installed between the other end of the rotating shaft 96 and the lead screw 109. In this invention, the output shaft of the drive motor 91 is provided with a third gear 92 and a first conical tooth 94, so that the lead screw 109 and the third gear ring 93 rotate synchronously, driving the device to work.

[0041] The work process is as follows:

[0042] Start the drive motor 91, and drive the first upper base plate 63 to rotate through the meshing of the third gear 92 and the third gear ring 93, thereby driving the first lower base plate 61 to rotate and the grinding roller 62 to revolve; through the meshing of the pinion 64 and the first gear ring 66, the grinding roller 62 rotates on its own axis.

[0043] The rotation of the first lower base plate 61 drives the first gear 68 to rotate, which in turn drives the second gear 82 to rotate, thereby driving the second gear ring 83 to rotate in the opposite direction, which in turn drives the second upper base plate 71 to rotate, thereby driving the second lower base plate 72 and the correction roller 73 to rotate.

[0044] The drive motor 91 synchronously drives the first bevel tooth 94 to rotate. The first bevel tooth 94 and the second bevel tooth 97 mesh with each other, thereby driving the second bevel tooth 97 to rotate, which in turn drives the rotating shaft 96 to rotate. The rotating shaft 96 is connected to the lead screw 109 by the belt 98, thereby driving the lead screw 109 to rotate.

[0045] The rotation of the lead screw 109 causes the square block 1010 to move left and right on the lead screw 109, which in turn drives the piston rod 1011 to move inside the air cylinder 108. This increases the air pressure in the air cylinder 108 and the cylindrical slide groove 103, which in turn drives the piston rod 105 to move the blade 104 forward to cut the copper wire.

[0046] Of course, those skilled in the art should understand that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple. The term "a" should not be understood as a limitation on the quantity.

[0047] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art under the technical guidance of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
