[0032] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0036] The manufacturing process for motor windings places extremely high demands on the cleanliness and precision of the wire. This is especially true in the manufacture of high-precision equipment such as disc motors, where the quality of the wire directly impacts the performance of the final winding and the overall efficiency of the motor. With technological advancements, square-section wire has gradually become the preferred material for motor windings due to its higher fill factor and excellent electrical properties. However, during the manufacturing, transportation, and storage of the wire, the wire surface often becomes contaminated with various impurities and oils. If these impurities and oils are not promptly removed, they can affect the quality of the wire during subsequent winding, preventing the windings from fitting tightly together, which in turn affects the efficiency, heat dissipation, and service life of the motor. Furthermore, foreign matter adhering to the wire surface during wire straightening can also affect the alignment.

[0037] To this end, this embodiment provides a wire cleaning mechanism, which is particularly suitable for wires 100 with square cross-sections. The wire cleaning mechanism is arranged upstream of the wire straightening mechanism and can clean the wire 100 before the wire 100 is straightened.

[0038] Specifically, if Figure 1 and Figure 2As shown, the wire cleaning mechanism includes a first cleaning assembly 10 and two guide rollers 20. The first cleaning assembly 10 includes a first pressure plate 11, a carrier plate 12, and a first cleaning layer 13. The first pressure plate 11 is fixedly connected to the carrier plate 12. The first cleaning layer 13 is disposed between the first pressure plate 11 and the carrier plate 12, and the wire 100 can pass through the first cleaning layer 13. The two guide rollers 20 are located upstream of the first cleaning layer 13 and are disposed on the first pressure plate 11 or the carrier plate 12 in the left-right direction. The wire 100 can pass between the two guide rollers 20. The wire 100 is transported from back to front.

[0039] When in use, the wire 100 first passes between the two guide wheels 20. Under the guidance of the guide wheels 20, the wire 100 then passes through the first cleaning layer 13. In this way, the wire 100 is restricted by the guide wheels 20 to ensure that it does not move and escape from the first cleaning layer 13 during the cleaning process. The wire 100 passes through the first cleaning layer 13 and contacts and rubs with the first cleaning layer 13, so that the upper and lower surfaces of the wire 100 can be effectively cleaned, thereby removing impurities and oil stains on the upper and lower surfaces of the wire 100. The reason for cleaning the upper and lower surfaces of the wire 100 is that after winding, the wires 100 are in contact with each other through these two surfaces, which can ensure that the windings are closely fitted in the subsequent winding process, thereby ensuring the close fit and electrical performance of the windings.

[0040] In an optional embodiment, if Figure 3 As shown, the first cleaning layer 13 includes two stacked felt sheets 131, between which the wire 100 can pass. Guided by the guide wheel 20, the wire 100 maintains its accurate left-right position and passes between the two tightly pressed felt sheets 131. As the wire 100 passes between the two felt sheets 131, it rubs against the two felt sheets 131, effectively cleaning the upper and lower surfaces of the wire 100. Furthermore, the felt sheets 131 are easy to obtain and relatively inexpensive.

[0041] In an optional embodiment, if Figure 2 and Figure 4 As shown, a first waist hole 112 extending in the left-right direction is formed on the first pressing plate 11 at a position corresponding to each guide wheel 20. A screw 21 is provided at one end of the rotating shaft of the guide wheel 20. The screw 21 is passed from bottom to top through the first waist hole 112 and is then threadedly fastened to the first nut 22, thereby fixing the guide wheel 20 to the first pressing plate 11. In addition, the holes for installing the guide wheels 20 are configured in the form of waist holes, which allows the spacing between the two guide wheels 20 to be adjusted, thereby accommodating wires 100 of different diameters or widths, thereby improving flexibility of use.

[0042] In an optional embodiment, if Figure 1 and Figure 2 As shown, the wire cleaning mechanism also includes a pair of pressure wheels 40 located downstream of the first cleaning component 10 and arranged opposite to each other in the up and down directions, and the wire 100 can pass between the two pressure wheels 40. In this way, by virtue of the joint restriction of the pressure wheel 40 and the guide wheel 20, it can be ensured that the wire 100 does not move and fall off the felt sheet 131 during the cleaning process, so that the upper and lower surfaces of the wire 100 can be effectively cleaned, thereby ensuring the tight fit and electrical performance of the winding. In addition, it should be noted that another function of the pressure wheel 40 in the whole line is to cooperate with the straightening and compounding of the downstream wire 100, and to prevent the two wires 100 compounded together from peeling off from each other. It should also be noted that the structure for installing the pressure wheel 40 can also be set in a form similar to the above-mentioned waist hole to adjust the upper and lower positions of the pressure wheel 40, which will not be repeated here.

[0043] In an optional embodiment, if Figures 2 to 4 As shown, the first pressing plate 11 is provided with two first through holes 113 arranged at intervals along the left-right direction, and the carrier plate 12 is provided with a second through hole (not shown) at a position corresponding to the first through hole 113. The bolt 14 passes through the first through hole 113 and the second through hole in sequence and is fastened to the second nut 15. Among them, the first through hole 113 and the second through hole can be selected as light holes. After the first pressing plate 11 is pressed on the first cleaning layer 13, the bolt 14 passes through the light holes in sequence and can be threadedly fastened to the two second nuts 15. The two second nuts 15 are respectively located on the upper and lower sides of the carrier plate 12. After the two second nuts 15 are tightened at the same time, the first pressing plate 11 and the carrier plate 12 can be firmly connected. In the above manner, the first pressing plate 11 for pressing and fixing the felt sheet 131 can be detachably mounted on the carrier plate 12, so that the felt sheet 131 can be replaced regularly to maintain the cleaning effect.

[0044] In an optional embodiment, if Figure 1 As shown, the wire cleaning mechanism further includes a bracket 30, and the carrier plate 12 is adjustable in the vertical direction on the bracket 30. In this way, it can adapt to the upstream and downstream direction of the wire 100, so that the position of the felt sheet 131 corresponds to the position between the upstream guide wheel 20 and the downstream pressure wheel 40.

[0045] Specifically, if Figure 1As shown, the bracket 30 is provided with two second side holes 31 on opposite sides in the left-right direction. The second side holes 31 extend in the vertical direction. The carrier plate 12 is provided with connecting holes 121 at positions corresponding to the second side holes 31. Fasteners (not shown) are sequentially inserted through the second side holes 31 and the connecting holes 121 to secure the carrier plate 12 to the bracket 30. The connecting holes 121 are threaded holes, and the fasteners can be screws, bolts, etc. By setting the second waist hole 31, the position of the carrier plate 12 can be fine-tuned in the up and down directions, that is, the up and down positions of the first cleaning component 10 can be adjusted, so as to adapt to the upstream and downstream directions of the wire 100, so that the felt sheet 131 corresponds to the position between its upstream guide wheel 20 and the downstream pressure wheel 40, respectively, that is, the upper and lower felt sheets 131 can be pressed evenly on the upper and lower surfaces of the wire 100 respectively. That is to say, while ensuring the cleaning effect, the precise assembly position of the first pressure plate 11 and the carrier plate 12 can prevent the wire 100 from being subjected to stress or even bending when entering the felt sheet 131.

[0046] In an optional embodiment, the bolt 14 is a butterfly bolt. By adopting the butterfly bolt, manual operation by the operator is facilitated, the dependence on tools is reduced, and time and labor are saved.

[0047] In an optional embodiment, if Figure 4 As shown, a plurality of blocks 111 are provided on the bottom surface of the first pressure plate 11, and the plurality of blocks 111 together enclose a space for accommodating the upper felt sheet 131, thereby preventing the felt sheet 131 from moving back and forth. At the same time, the limiting effect of the two bolts 14 in the left and right directions can also limit the left and right movement of the felt sheet 131.

[0048] In an optional embodiment, the lower felt sheet 131 may be bonded to the carrier plate 12 by glue, or a plurality of stoppers 111 may be provided on the carrier plate 12 to prevent the lower felt sheet 131 from moving back and forth.

[0049] In an optional embodiment, if Figure 1 As shown, the wire cleaning mechanism further includes a second cleaning assembly 50 located downstream of the pressing wheel 40. The second cleaning assembly 50 includes a second pressing plate 51, a support frame 53, and a second cleaning layer 52. The second pressing plate 51 is fixedly connected to the support frame 53. The second cleaning layer 52 is disposed between the second pressing plate 51 and the support frame 53, and the wire 100 can pass through the second cleaning layer 52. The second cleaning layer 52 has the same structure as the first cleaning layer 13 and is also composed of a pair of stacked felt sheets 131. The second pressing plate 51 is fastened to the support frame 53 to compress the two felt sheets 131 therebetween.

[0050] In this embodiment, the second cleaning layer 52 may be as follows Figure 1As shown, it is still used to clean the upper and lower surfaces of the wire 100. Of course, it can also be rotated 90 degrees to clean the left and right surfaces of the wire 100. This is generally based on process requirements or the actual dirtiness of the wire 100. In fact, in the verified equipment, the applicant only set the first cleaning component 10 upstream of the pressing wheel 40, and did not continue to set the second cleaning component 50 downstream of the pressing wheel 40. The main reason is that the thickness of the wire 100 is relatively small, so there is no need to clean the side. It is understandable that when the thickness of the wire 100 is relatively large, there should also be a need to clean the side, that is, it is necessary to set the second cleaning component 50.

[0051] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
