[0015] The embodiments of this utility model will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement them after reading this specification. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0016] This utility model provides a flat coil insulation varnish stripping machine, including a mill 10, a stripping fixture 20, and a pressing block 30.

[0017] Please refer to Figure 1-2The mill 10 includes a motor 11 and a grinding head 12 mounted on the output shaft of the motor 11. The outer circumferential surface of the grinding head 12 is provided with a cutting edge. The mill 10 also includes a height adjustment device to accommodate flat copper wires of different thicknesses. The height adjustment device includes an adjustment bracket 13, a lead screw 14 rotatably connected to the adjustment bracket 13, a guide post 15 parallel to the lead screw 14, and a slider 16 slidably connected to the guide post 15. The lead screw 14 extends vertically and is threadedly connected to the slider 16. The slider 16 is provided with a connecting plate 17, and the motor 11 is mounted on the connecting plate 17. The lead screw 14 is also provided with a rotating wheel 141. Rotating the rotating wheel 141 drives the lead screw 14 to rotate, thereby causing the slider 16, the connecting plate 17, and the mill 10 to move vertically up and down, adjusting the grinding head 12 to a suitable height. In other embodiments, the height adjustment device may also be a robotic arm, an electric linear module, or other similar forms.

[0018] Preferably, the connecting plate 17 is further provided with a splash guard 171 extending above the grinding head 12 to prevent debris generated during the removal of insulating varnish from splashing upwards into the worker's eyes and causing a safety accident.

[0019] Please refer to Figure 1 , 2 The paint stripping fixture 20 includes a guide rail 21 arranged parallel to the pins of the flat coil 40, a slide table 22 slidably connected to the guide rail 21, and a coil fixture 23 detachably connected to the slide table 22.

[0020] The coil fixture 23 can be bolted to the slide table 22. Different specifications of coil fixture 23 can be used for flat coils of different sizes. Please refer to... Figure 3 The coil fixture 23 includes a positioning platform 231. The positioning platform 231 is provided with a first positioning post 232 that mates with the central hole of the flat coil 40, a second positioning block 233 that mates with the gap between the two pins of the flat coil 40, and a pad 234 disposed on one side of the second positioning block 233. When the flat coil is placed into the coil fixture, the bottom surface of the flat coil 40 is in contact with the positioning platform 231. The first positioning post 232 and the second positioning block 233 fix the position of the flat coil 40. Since the two pins have different heights, the pad 234 is used to support the pin with the higher height.

[0021] Furthermore, the paint stripping fixture 20 is also equipped with a limiting component to restrict the sliding stroke of the slide table 22, thereby controlling the paint stripping length of the pins. The paint stripping fixture 20 includes a guide rail bracket 24, with a guide rail 21 mounted on the guide rail bracket 24. The limiting component includes an adjusting bolt 251 threadedly connected to the guide rail bracket 24. The adjusting bolt 251 is parallel to the guide rail 21, and a limiting head 252 is provided on the side of the adjusting bolt 251 facing the slide table 22. By rotating the adjusting bolt 251, the position of the limiting head 252 can be adjusted to adapt to various working conditions with different pin paint stripping lengths. Specifically, the adjustment method is as follows: after placing the flat coil 40 in the paint stripping fixture 20, with the central axis of the grinding head 12 as the dividing line, push the slide table 22 towards the limiting head 252 until the pin exceeds the dividing line to reach the required paint stripping length, and then rotate the adjusting bolt 251 to bring the limiting head 252 into contact with the slide table 22.

[0022] The pressure block 30 is used to press the flat coil 40 against the coil fixture 23. Please refer to... Figure 1 , 2 The pressure block 30 is provided with a groove that mates with the first positioning post 232 and a handle 31 that is easy for workers to hold. The handle 31 is also provided with a support foot 32 that extends to the coil tooling 23 to enhance the stability of the handle 31.

[0023] In such Figure 1 In one embodiment shown, the grinding mill 10 is positioned to the left of the paint stripping fixture 20. The central axis of the grinding head 12 is typically perpendicular to the guide rail 21, and only the surface of one pin of the flat coil 40 is stripped of paint. In use, the flat coil 40 is first installed into the coil fixture 23, with the first pin of the flat coil 40 facing the grinding head 12 and the second pin on the pad 234. Then, the pressure block 30 is placed on top, its groove engaging the first positioning post 232 to press the coil firmly. The position of the limiting head 252 is then adjusted, and the grinding head 12 is adjusted to the height where the paint layer needs to be removed. The motor is started, and the worker holds the handle 31 to push the slide table 22, moving the first pin to the grinding head 12 to remove the paint layer until the slide table 22 contacts the limiting head 252. The slide table 22 is then pushed back to reset, completing the paint stripping of one surface of the first pin. The coil is then reversed to complete the paint stripping of one surface of the second pin.

[0024] In another embodiment, the mill 10 is positioned to the right of the paint stripping fixture 20 to remove paint from the other surface of the second pin; the coil is reversed to remove paint from the other surface of the first pin.

[0025] In other embodiments, the paint stripping fixture 20 is equipped with a grinder 10 on both sides, which can simultaneously strip the paint from one surface of the two pins of the flat coil 40, and then reverse the coil to strip the paint from the other surface of the two pins.

[0026] The above describes one or more embodiments of this utility model in a relatively specific and detailed manner, but it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
