[0028] The core of the utility model is to disclose an anti-fog treatment device for a lamp mask to improve the anti-fog effect of a vehicle lamp.

[0029] Another core of the present invention is to disclose a vehicle lamp cover and a vehicle lamp.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1 As shown, an embodiment of the present utility model discloses an anti-fog treatment device for a lamp mask, comprising a plasma device 10 , a driving device, a distance measuring device 30 and a control device 40 .

[0032] The plasma device 10 processes the inner surface of the lamp mask 20, and the plasma device 10 includes a plasma torch 11. The driving device is connected to the lamp mask 20 by transmission, driving the lamp mask 20 to move, thereby adjusting the distance between the plasma torch 11 and the lamp mask 20. The distance measuring device 30 is used to measure the distance between the plasma torch 11 and the lamp mask 20. The distance measuring device 30 and the driving device are both connected to the control device 40. The distance measuring device 30 transmits a measured distance signal between the plasma torch 11 and the lamp mask 20 to the control device 40. The driving device adjusts the distance between the plasma torch 11 and the lamp mask 20 to within a preset distance range based on the distance signal.

[0033] It should be noted that the plasma treatment apparatus 10 causes various physical and chemical changes to the material surface, including etching and roughening, forming a dense cross-linked layer, and introducing oxygen-containing polar groups, thereby improving hydrophilicity, adhesion, dyeability, biocompatibility, and electrical properties. Treating the material surface under appropriate process conditions significantly alters the surface morphology, introducing various oxygen-containing groups and transforming the surface from a non-polar, difficult-to-adhere state to a somewhat polar, easily adhesive, and hydrophilic state, facilitating bonding, coating, and printing.

[0034] The inner surface of the lamp mask 20 is treated by using the plasma device 10 to modify the inner surface of the lamp mask 20 to form a dense cross-linked layer, thereby improving the hydrophilicity and achieving an anti-fog paint effect.

[0035] The lamp mask anti-fog treatment device disclosed in the embodiment of the present invention processes the surface of the lamp mask 20 through the plasma device 10, which can improve the hydrophilicity of the lamp mask 20, combine the hydrophilic groups with water molecules, reduce the contact angle between water and the lamp mask 20, and then make the water vapor highly spread when condensed on the surface of the substrate, forming a uniform water film, eliminating the diffuse reflection of light, and thus achieving an anti-fog effect. The setting of the driving device can adjust the distance between the lamp mask 20 and the plasma torch 11 in real time to ensure that the distance between the lamp mask 20 and the plasma torch 11 is within a preset distance range, ensure the uniformity of the surface treatment of the lamp mask 20 by the plasma torch 11, and further improve the anti-fog effect. The setting of the control device can improve the degree of automation of the lamp mask anti-fog treatment device and improve production efficiency.

[0036] The anti-fog treatment device for a lamp mask disclosed in the embodiment of the utility model can reduce costs compared with the anti-fog coating technology used in the prior art.

[0037] It should be noted that the plasma equipment 10 includes a power supply, a high-frequency generator and an induction coil, a plasma torch 11, a gas supply system, a control system and a vacuum system, wherein the high-frequency generator generates a high-frequency current, and the induction coil uses this high-frequency current to generate plasma. The gas supply system provides the necessary gas to maintain the stability of the plasma. The power supply system provides power supply to ensure the normal operation of the equipment. The control system is used for data adjustment and equipment control. The vacuum system includes a vacuum pump, a vacuum valve, a vacuum measuring instrument, etc. to ensure that the equipment operates in a vacuum environment.

[0038] In order to adjust the distance between the plasma torch and the lamp mask 20, the driving device can drive the lamp mask 20 to move along a first direction. Specifically, the first direction refers to the extension direction of the plasma torch 11. Figure 1 The first direction shown in is the horizontal direction.

[0039] There are various configuration options for the drive device. For example, a drive motor and a screw-nut mechanism can be used, with the lamp mask 20 connected to the nut in the screw-nut mechanism. The drive motor drives the screw to rotate, and the nut moves along the axis of the screw to drive the lamp mask 20 to move, thereby adjusting the distance between the plasma torch 11 and the lamp mask 20. The drive device can also use a drive cylinder, with the lamp mask 20 being provided on the piston rod of the drive cylinder, and the distance between the plasma torch 11 and the lamp mask 20 being adjusted by the extension and retraction of the piston rod. It will be understood by those skilled in the art that the drive device can also adopt other solutions.

[0040] In some specific embodiments, the driving device may be a robot.

[0041] In other specific embodiments, the driving device can drive the lamp cover 20 to move along the second direction, the second direction is perpendicular to the first direction, and the second direction refers to the extension direction perpendicular to the plasma torch 11, such as Figure 1 As shown in , the first direction refers to the horizontal direction, and the second direction refers to the vertical direction. The driving device can drive the lamp mask 20 to move along the second direction, so that the plasma torch 11 can more evenly treat the surface of the lamp mask 20. On the other hand, the lamp mask 20 may include multiple lamp masks arranged in sequence along the second direction. The driving device drives the lamp mask 20 to move in the second direction, so that the plasma torch 11 can sequentially treat the multiple lamp masks 20, which can save time.

[0042] In some specific embodiments, the driving device includes a first cylinder, a second cylinder, a first platform, and a second platform. The first platform is connected to the piston rod of the first cylinder, the second cylinder is disposed on the first platform, and the second platform is connected to the piston rod of the second cylinder. The piston rod of the first cylinder is arranged along a first direction, and the piston rod of the second cylinder is arranged along a second direction. The lamp mask 20 is disposed on the second platform, and both the first cylinder and the second cylinder are connected to a control device 40. The first cylinder can adjust the distance between the plasma torch 11 and the lamp mask 20, and the second cylinder can move the lamp mask 20 in a direction perpendicular to the extension direction of the plasma torch 11, so that the plasma torch 11 can fully treat the surface of the lamp mask 20. At the same time, multiple lamp masks 20 arranged sequentially along the second direction can be treated.

[0043] In other specific embodiments, the driving device also includes a driving motor and a rotating platform connected to the driving motor. The first cylinder is arranged on the rotating platform. The driving motor can drive the rotating platform to rotate, and then drive the lamp mask 20 to rotate, so that the plasma torch 11 can process the surface of the lamp mask 20 in all directions, so that the treatment is more uniform, thereby improving the anti-fog effect.

[0044] The distance measuring device 30 may be a laser distance measuring device, an ultrasonic distance measuring device or an infrared distance measuring device.

[0045] In order to ensure the treatment effect of the plasma torch 11 on the surface of the lamp cover 20, the distance between the plasma torch 11 and the lamp cover 20 is 35mm-45mm.

[0046] In some specific embodiments, the speed of the plasma torch 11 is 0.4 m / s-0.6 m / s, and the inner surface of the lamp cover 20 is processed in an S-shaped rotation manner.

[0047] The anti-fog treatment device for the lamp mask disclosed in the embodiment of the present invention has the following specific parameter settings for the plasma equipment 10: the pressure setting range is 2bar-8bar, the gas flow setting range is 30L / min-80L / min, the current is not less than 68mA, and the rotation speed of the plasma torch 11 is not less than 1500r / min.

[0048] After the surface treatment of the lamp mask 20 is completed using the plasma equipment 10, the quality of the treatment can be verified in the following way: spray talcum powder on the inner surface of the lamp mask 20, manually shake the talcum powder to make the talcum powder evenly distributed on the inner surface of the lamp mask 20. If the talcum powder on the inner surface of the lamp mask 20 is evenly adhered, it indicates that the surface treatment effect of the plasma equipment 10 is good.

[0049] In addition, an embodiment of the present utility model further discloses a vehicle lamp mask, the inner surface of which is treated by the above-mentioned anti-fog treatment device for the lamp mask.

[0050] The embodiment of the utility model further discloses a vehicle lamp, comprising the above-mentioned vehicle lamp mask.
