Two-color injection molded covers can prevent the internal structure of the light fixture from being exposed and gaps that affect the appearance. However, two-color covers are usually made of PC material through injection molding. After injection molding, injection gates will be formed on the cover. Exposed injection gates directly affect the appearance quality of the light fixture.

[0003] Exposed gates are typically removed by grinding with a grinder. However, the debris and dust generated during grinding can easily contaminate or scratch the surface of the mask. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this disclosure provides a method for removing gates from the surface of a face mask, a face mask, a vehicle light, and a vehicle.

[0006] A first shielding element is placed over a first area on the face mask to shield and protect the first area; wherein the first area and the gate area on the face mask do not overlap.

[0007] The first shielding member is fixed to the face mask by a fastener; wherein the fastener extends to the side of the first shielding member near the gate area, and the edge of the fastener near the gate area defines a grinding reference surface.

[0008] Grinding is performed along the grinding reference surface on the gate area to remove the gate on the mask.

[0009] Optionally, before the step of covering the first area of ​​the face mask with the first shielding element to shield and protect the first area, the method further includes:

[0011] The step of grinding the gate area along the grinding reference surface to remove the gate on the mask specifically includes:

[0012] The second shielding member, which covers the gate but is not covered by the fixing member, is polished along the polishing reference surface.

[0013] Optionally, the second masking element is a color-blocking tape that can be peeled off from the mask, which is attached to the gate area to mask and cover the gate area.

[0014] Optionally, after the step of grinding the gate area along the grinding reference surface until the gate on the mask is removed, the method further includes:

[0015] The polished area on the mask is covered to form a masking layer on the surface of the polished area.

[0016] The color of the side of the shielding layer facing away from the mask is the same as the color of the mask surface located on the outer periphery of the polished area.

[0017] Optionally, the masking layer is a masking tape adhered to the surface of the area after it has been polished.

[0018] Alternatively, the masking layer may be a paint layer or a metal plating layer covering the polished area.

[0025] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0026] The method for removing gates from the surface of a face mask disclosed herein uses a fixing member to cover a first shielding member on a first area of ​​the face mask, so that the first shielding member can protect the first area and prevent debris from flying during grinding from scratching the first area of ​​the face mask. The first area and the gate area on the face mask do not overlap, so that the gate is exposed on the outside of the first shielding member for easy grinding. The grinding reference surface formed by the edge of the fixing member limits the grinding range when grinding the gate, avoiding excessive grinding range and damage to the face mask. This method removes the gates on the face mask while improving grinding accuracy, thereby improving the aesthetics of the face mask after the gates are removed. Attached Figure Description

[0037] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0038] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0039] A first aspect of this disclosure provides a method for removing gates from the surface of a face mask, the method comprising:

[0040] S101. The first shielding member 3 is covered on the first area of ​​the mask 1 to shield and protect the first area; wherein the first area and the gate area on the mask 1 do not overlap.

[0041] Specifically, such as Figures 1 to 5 As shown, the gate 2 is located at one end of the mask 1. The end of the mask 1 near the gate 2 can include a first surface 11, a second surface 12, and a third surface 13. The first surface 11 and the third surface 13 are connected to the two sides of the second surface 12 along the first direction. The first surface 11 and the third surface 13 are arranged opposite to each other along the first direction. The gate 2 is a protruding structure and is located on the second surface 12. The second surface 12 can be selected as the gate area, or the area within a certain distance from the gate 2 can be selected as the gate area. The first direction can be selected as a vertical direction or a horizontal direction.

[0042] The first region is the area where the first shielding member 3 shields the mask 1. The first region can be the first surface 11, or the third surface 13, or both the first surface 11 and the third surface 13. That is, the first shielding member 3 can shield either the first surface 11 or the third surface 13. Alternatively, one edge of the first shielding member 3 can be located on the first surface 11, and the first shielding member 3 can be bent so that the other edge of the first shielding member 3 can bypass the end of the mask 1 away from the gate 2 and be located on the third surface 13, so that the first shielding member 3 can shield both the first surface 11 and the third surface 13 at the same time.

[0043] When the first shielding member 3 is located on the first surface 11 or the third surface 13, the first shielding member 3 shields the first surface 11 or the third surface 13 while exposing the second surface 12, so that the first area does not overlap with the gate area. Alternatively, the edge of the first shielding member 3 near the gate 2 can extend to the second surface 12, and the edge of the first shielding member 3 near the gate 2 can be located at the edge of the gate area on the second surface 12, so that the first area does not overlap with the gate area. When the first shielding member 3 shields both the first surface 11 and the third surface 13 at the same time, both sides of the first shielding member 3 can be located on the first surface 11 and the third surface 13, so that the first shielding member 3 exposes the second surface 12, so that the first area does not overlap with the gate area.

[0044] The first shielding element 3 mentioned above can be a shielding film. The shielding film fits and covers the first area of ​​the mask 1 so that the debris and droplets during the grinding of the gate 2 will not scratch the first area of ​​the mask 1. Of course, the first shielding element 3 can also be a plastic film or a rubber film, as long as the first shielding element 3 can shield the first area so that the debris and droplets from grinding the gate 2 will not contaminate or scratch the first area of ​​the mask 1.

[0045] Of course, it is not limited to the mask 1, which includes the first side 11, the second side 12 and the third side 13. The mask 1 can also be selected as other shapes. The gate area is the area within a certain range of distance from the gate 2. The first area and the gate area do not overlap, so that the first shielding member 3 will not cover the gate area.

[0046] S102. The first shielding member 3 is fixed to the mask 1 by the fastener 4; wherein the fastener 4 extends to the side of the first shielding member 3 near the gate area, and the edge of the fastener 4 near the gate area defines the grinding reference surface 43.

[0047] Specifically, the fixing member 4 can be an adhesive tape, which is placed on the first shielding member 3 and extends towards the gate 2, so that part of the tape is located on the edge of the first shielding member 3 near the gate 2, so that the tape can be adhered to the mask 1 and the first shielding member 3 can be adhered to the mask 1 by the tape; or the fixing member 4 can be two magnets, which are located on both sides of the first shielding member 3 along the first direction and are magnetically connected to each other. Part of the magnets cover the edge of the first shielding member 3 near the gate area, so that when the two magnets are magnetically connected to each other, the first shielding member 3 is connected to the first area of ​​the mask 1.

[0048] When the aforementioned fastener 4 is an adhesive tape, and the first region includes the first surface 11 and the third surface 13, the fastener 4 can be selected to include a first adhesive tape 41 and a second adhesive tape 42. The first adhesive tape 41 is disposed on the edge of the first shielding member 3 on the first surface 11 and is bonded to the first surface 11. The second adhesive tape 42 is disposed on the edge of the first shielding member 3 on the third surface 13 and is bonded to the third surface 13. The edges of the first adhesive tape 41 and the second adhesive tape 42 near the gate 2 together form the grinding reference surface 43.

[0049] The aforementioned fixing member 4 has a straight edge near the gate area. When the first shielding member 3 is located on the first surface 11 and the third surface 13 of the mask 1, the first surface 11 and the third surface 13 are respectively provided with fixing members 4 to connect the first shielding member 3 to the mask 1. The fixing members 4 on the first surface 11 and the third surface 13 are coplanar near the edge of the gate 2 to form a grinding reference surface 43, for example. Figure 3 and Figure 4 As shown; the boundary line between the gate 2 and the mask 1 can be located on the grinding reference surface 43, or the boundary line between the gate 2 and the mask 1 can be located on the side of the grinding reference surface 43 closer to the mask 1, and there is a set distance between the boundary line between the gate 2 and the mask 1 and the grinding reference surface 43; of course, when the first shielding member 3 is located on the first surface 11 or the third surface 13, the plane where the fixing member 4 on the first surface 11 or the third surface 13 is located near the edge of the gate 2 can be used as the grinding reference surface 43, and the grinding reference surface 43 is perpendicular to the direction of the gate 2 protruding relative to the mask 1. The boundary line between the gate 2 and the mask 1 can be located on the grinding reference surface 43, or the boundary line between the gate 2 and the mask 1 can be located on the side of the grinding reference surface 43 closer to the mask 1, and there is a set distance between the boundary line between the gate 2 and the mask 1 and the grinding reference surface 43.

[0050] S103. Grind the gate area along the grinding reference surface 43 to remove the gate 2 on the mask 1.

[0051] Specifically, a grinding setting can be used to grind the gate area, such as an angle grinder or a grinding wheel. The grinding equipment can be equipped with a grinding surface, which can be parallel to the grinding reference surface 43. Grinding stops when the grinding surface contacts the grinding reference surface 43. During the grinding operation, the grinding wheel of the corneal machine can be parallel to the grinding reference surface 43. After the angle grinder is started, the grinding wheel is kept parallel to the grinding reference surface 43. The grinding wheel moves towards the mask 1 and gradually grinds and removes the gate 2. When the grinding surface of the grinding wheel moves to contact the edge of the fixing part 4 near the gate 2, grinding stops. While removing the gate 2, it is ensured that the grinding area is not too large and damages the mask 1.

[0052] The method for removing gates from the surface of a face mask provided in this embodiment uses a fixing member 4 to cover the first shielding member 3 on the first area of ​​the face mask 1, so that the first shielding member 3 can protect the first area and prevent the first area of ​​the face mask 1 from being scratched by flying debris during grinding. The first area and the gate area on the face mask 1 do not overlap, so that the gate 2 is exposed on the outside of the first shielding member 3 for easy grinding. The grinding reference surface 43 formed by the edge of the fixing member 4 limits the grinding range when grinding the gate 2, and avoids the grinding range being too large and damaging the face mask 1. This method removes the gate 2 on the face mask 1 while improving the grinding accuracy, thereby improving the aesthetics of the face mask 1 after the gate 2 is removed.

[0053] In some embodiments, after step S103, the method may further include step S104: removing the first shielding member 3 and the fixing member 4 from the mask 1.

[0054] Specifically, when the fastener 4 is tape, the fastener 4 is torn off from the face mask 1, thereby removing the first shielding member 3 and the fastener 4 together from the face mask 1.

[0055] When the fixing member 4 is a magnet, the magnets on both sides of the mask 1 are separated, thereby removing the fixing member 4 and the first shielding member 3 from the mask 1.

[0056] In some embodiments, prior to step S101, the method further includes step S105: covering a second region on the mask 1 with a second shielding member 5; wherein the second region covers at least the gate region, and the edge of the second shielding member 5 is covered by the fixing member 4.

[0057] Specifically, the second masking component 5 can be made of color-blocking tape. The color-blocking tape is adhered to the second area to cover it. The color of the color-blocking tape of the second masking component 5 can be different from the color of the fixing tape of the fixing component 4, so as to distinguish the fixing component 4 and the second masking component 5 on the mask 1. The color-blocking tape can be made of polyethylene terephthalate or polyvinyl chloride.

[0058] The gate area can be selected as the second surface 12 or the area on the second surface 12 that is within a certain distance from the gate 2. The second surface 12, the part of the first surface 11 that is close to the second surface 12 and the part of the third surface 13 that is close to the second surface 12 form the second area, making the second area larger than the gate area and covering the gate area. The side of the first shielding member 3 that is close to the gate area can be selected to partially overlap with the side of the second area that is far away from the gate area. The fixing member 4 is bonded to the first shielding member 3 and the second shielding member 5 on the second area, so that the first shielding member 3 is fixed to the mask 1 by the fixing member 4 and the second shielding member 5.

[0059] Accordingly, during the grinding process, the gate 2 and the portion of the second shielding member 5 covering the gate 2 but not covered by the fixing member 4 are ground together along the grinding reference surface 43.

[0060] Specifically, since the second region is larger than the gate region, the gate 2 is located in the gate region. Part of the second shielding member 5 covers the gate 2, and the remaining part of the second shielding member 5 is located around the gate 2. The part of the second shielding member 5 that is not covered by the fixing member 4 is located on the grinding reference surface 43 away from the mask 1, so that when the grinding equipment grinds the gate 2, the second shielding member 5 covering the gate 2 will be ground and removed simultaneously.

[0061] Since the gate 2 is located in the gate area, which is located in the second area, when using a grinding device to grind the gate area to remove the gate 2, it is easy to scratch the part of the second area close to the gate area. The protection range of the first shielding member 3 is limited, and the part of the mask 1 in the second area is still easily contaminated and scratched. By setting the second shielding member 5 on the second area, the second shielding member 5 can shield the gate area and the second area. When grinding the gate 2, the second shielding member 5 covering the gate 2 is ground and removed at the same time. The debris splashed when grinding the gate 2 can only come into contact with the second shielding member 5 covering the second area. The second shielding member 5 protects the part of the mask 1 located in the second area when grinding the gate 2, and avoids scratches on the mask 1 when grinding the gate 2. The first shielding member 3 and the second shielding member 5 work together to achieve shielding and protection of each position of the mask 1.

[0062] In some embodiments, the method further includes removing at least the portion of the first shielding member 3, the fastener 4, and the second shielding member 5 covered by the fastener 4 from the mask 1.

[0063] Specifically, when the first shielding element 3 is a shielding film, the fixing element 4 is tape, and the second shielding element 5 is tape, the second shielding element 5 can be removed from the face mask 1 by tearing it off. The second shielding element 5, the fixing element 4, and the first shielding element 3 can then be removed from the face mask 1.

[0064] like Figure 6 As shown, in some embodiments, after the gate 2 is removed by grinding, the method further includes: covering the ground area on the mask 1 to form a masking layer 6 on the surface of the ground area; wherein the color of the side of the masking layer 6 facing away from the mask 1 is the same as the color of the surface of the mask 1 located on the periphery of the ground area.

[0065] Specifically, after the gate 2 is ground using a grinding machine, the area within the gate area after the gate 2 has been removed by the grinding equipment is the ground area on the mask 1. Due to the wear and tear on the mask 1 caused by the grinding operation of the grinding equipment, the color and gloss of the ground area on the mask 1 will be inconsistent with the color and gloss of the first area of ​​the mask 1. Therefore, a masking layer 6 is set on the ground area of ​​the mask 1 to make the color of the masking layer 6 consistent with the first area of ​​the mask 1, thereby making the overall appearance color of the mask 1 consistent.

[0066] In some embodiments, the masking layer 6 is a masking tape adhered to the surface of the polished area. The masking tape may be selected to have a material and color consistent with the surface color of the mask 1. The masking tape is adhered to the polished area of ​​the mask 1 to form the masking layer 6. The masking tape is easy to apply, low in cost, and can easily cover the polished area of ​​the mask 1.

[0067] In other embodiments, the masking layer 6 is a paint layer or a metal plating layer covering the polished area. The masking layer is formed by spraying paint onto the polished area of ​​the mask 1, ensuring the paint color matches the surface color of the mask 1. Alternatively, electroplating or chemical plating can be used to apply a plating layer to the polished area of ​​the mask 1, ensuring the plating layer matches the color of the outer perimeter of the polished area on the mask 1 surface. The paint layer or metal plating layer remains stable on the mask 1 even under vibration and rain conditions, improving the stability of the masking layer 6 on the mask 1 and allowing the mask 1 to maintain a consistent appearance under different usage environments.

[0068] Understandably, the outer edge of the polished area is located within the coverage area of ​​the masking layer 6 on the face mask 1. Specifically, the area on the face mask 1 where the masking layer 6 covers and shields the surface of the face mask 1 is the coverage area of ​​the masking layer 6 on the face mask 1; the area of ​​the polished area can be selected to be less than or equal to the coverage area of ​​the masking layer 6 on the face mask 1, so that the masking layer 6 can completely shield the polished area.

[0069] In some embodiments, the fastener 4 is a masking tape that can be peeled off the face mask 1. Specifically, the masking tape is a roll of adhesive tape made primarily of masking paper and pressure-sensitive adhesive, with pressure-sensitive adhesive coated on one side and an anti-adhesive material coated on the other. It has properties such as high temperature resistance, excellent resistance to chemical solvents, high adhesion, softness and conformability, and leaves no residue when peeled off. The masking tape is soft and deformable, allowing it to adapt to the surface of the face mask 1 of different shapes, so that the edges of the first masking member 3 can be bonded to the face mask 1 through the masking tape. When the fastener 4 is removed from the face mask 1, the masking tape leaves no residue when peeled off, thus allowing the fastener 4 to be easily and completely removed from the face mask 1, improving the aesthetic appearance of the face mask 1.

[0070] In some embodiments, the first shielding member 3 is a flexible shielding film. Specifically, the flexible shielding film can be made of plastic and can be deformed so that the first shielding member 3 can be bent and located on the first surface 11 and the third surface 13 of the face mask 1, thereby conveniently protecting multiple sides of the face mask 1 and improving the ease of operation of setting the first shielding member 3 on different sides of the face mask 1.

[0071] Based on the same inventive concept, a second aspect of the present disclosure provides a face mask 1 having a first region and a gate processing region, wherein the first region and the gate processing region do not overlap; wherein the gate processing region is formed by processing the original gate region of the face mask by the method of removing the gate from the face mask surface as described above.

[0072] Specifically, the gate 2 formed on the original gate area of ​​the mask 1 is removed by grinding using the gate removal method described above, so as to obtain a smooth mask 1 with a gate treatment area.

[0073] By using the above-mentioned method for removing gates from the mask surface, the polishing precision is improved, scratches on the mask 1 are avoided, and the aesthetics of the mask 1 are enhanced.

[0074] A third aspect of this disclosure provides a vehicle light, including the mask described above.

[0075] By using the mask as described above in the headlight, the smooth and scratch-free mask 1 can serve as the outer shell structure of the headlight, preventing scratches on the mask 1 from interfering with the lighting effect of the headlight light after passing through the mask 1, thus ensuring the lighting effect of the headlight.

[0076] A fourth aspect of this disclosure provides a vehicle including the headlights described above.

[0077] By using the headlights described above in the vehicle, no scratches will be found on the headlight cover 1 when the gate 2 is polished. This avoids scratches on the cover 1 interfering with the lighting effect of the headlight light after passing through the cover 1, ensuring the lighting effect of the headlight and improving the aesthetics of the vehicle.

[0078] This embodiment may also optionally provide an electronic device, which includes a memory and a processor. The memory stores a computer program, and the processor executes the method for removing the gate from the mask surface provided in the above embodiment when executing the computer program. For example, the processor controls a robotic arm via a computer program to complete the operation of placing the first shielding member 3 on the mask 1 and using a grinding device to grind the gate 2 on the mask 1 along the grinding reference surface 43.
