Description

Technical Field

[0001] This invention belongs to the field of automotive film technology, and particularly relates to an automotive film transmittance display device with an adjustable light source. Background Technology

[0002] Automotive window film is a functional film applied to the surface of automotive glass. It is mainly divided into two categories: windshield film and side and rear window film. It uses PET as the base material and is made through processes such as magnetron sputtering, dyeing, and coating to give it properties such as heat insulation, sun protection, UV protection, privacy protection, and enhanced glass strength. It can effectively improve the comfort of the car interior, reduce the aging rate of the interior, and reduce the injury from flying debris in the event of accidental glass breakage. It is a commonly used protective product in the automotive aftermarket.

[0003] Light transmittance is a core indicator for measuring the visible light transmission capability of automotive window film. It is directly related to driving safety and regulatory compliance. Regulations clearly require that the light transmittance of windshield film be ≥70%, and the light transmittance of side and rear window films must also meet local traffic standards. Too low light transmittance will obstruct the driver's vision and increase the risk of accidents in scenarios such as night and tunnels. At the same time, light transmittance display can help consumers intuitively understand the product performance and find a balance between privacy protection and clear vision. It can also prevent consumers from facing penalties or safety hazards due to mistakenly choosing low light transmittance film. It is a necessary link to protect consumers' right to know and driving safety.

[0004] In the traditional testing and demonstration process of automotive window film transmittance, staff can only take a very small sample area for demonstration and testing. This sampling method cannot cover the entire length of the film roll, making it difficult to detect quality defects such as uneven light transmission and minor flaws in the film, which in turn brings potential risks to product quality control and subsequent user experience. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides: a device for displaying the light transmittance of automotive film with an adjustable light source, comprising: frame; Two symmetrically arranged first support frames are fixedly connected to the top of the frame, and one end of the uppermost first support frame is inclined. The second support frame is fixedly connected to the frame and located below the first support frame; A continuous film-moving assembly is mounted on the first support frame and the second support frame, and is used to drive the automotive film to rotate and move at a constant speed. A transmittance display component is mounted on the frame.

[0006] As a preferred embodiment of the present invention, the continuous film-moving assembly includes: Two flattening rollers rotatably connected to the first support frame at the top form a horizontal, straight film-feeding section; Each of the flattening rollers is fixedly connected to a symmetrically arranged first synchronous wheel, and a first synchronous belt is fitted onto the first synchronous wheel.

[0007] As a preferred embodiment of the present invention, the first support frame has three guide rollers rotatably connected to one side of its inclined shape; The guide roller is located on one side of the flattening roller, and the guide rollers are all placed at an angle. The first support frame at the top is located below the flattening roller and is rotatably connected to the first pair of pressure rollers. The first support below has a first slide rail; A first slider is slidably connected inside the first slide rail, and a second pair of pressure rollers are rotatably connected to the first slider. Both the first pair of pressure rollers and the second pair of pressure rollers are provided with patterns.

[0008] As a preferred embodiment of the present invention, an unwinding roller is rotatably connected to the second support frame; A first motor is installed on one side of the frame. The output end of the first motor and one end of the unwinding roller are both fixedly connected to a second synchronous pulley. A second synchronous belt is fitted onto the second synchronous pulley.

[0009] As a preferred embodiment of the present invention, the frame is rotatably connected to one side of the flattening roller; A semi-circular guide rail is fixedly connected to one side of the frame on the machine frame, and one side of the frame is slidably connected to the semi-circular guide rail. Two sets of smoothing wheels are provided on the frame.

[0010] As a preferred embodiment of the present invention, the two side walls of the frame are rotatably connected to first connecting rods; A telescopic rod is slidably connected to the first connecting rod; The extended end of the telescopic rod is fixedly connected to a first fixing plate, and a spring is installed between the first fixing plate and the fixed end of the telescopic rod. A limiting wheel that can contact the vehicle film is rotatably connected to the first fixing plate.

[0011] As a preferred embodiment of the present invention, the light transmittance display component includes: An inclined frame fixedly connected to one side of the frame; A second slider is slidably connected to the tilting frame, and a tension spring is fixedly connected between the second slider and the tilting frame.

[0012] In a preferred embodiment of the present invention, a fixed seat is slidably connected to the guide rod, a rotating disk is rotatably connected to the fixed seat, and adjustable light source modules symmetrically arranged vertically are fixedly connected to the rotating disk.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention belongs to the field of automotive film testing and display technology. Traditional automotive film transmittance display adopts a sampling display method, which can only cut out a very small area of ​​sample for testing. It cannot cover the entire length of the film and makes it difficult to detect quality defects such as uneven light transmission and minor flaws in the film. This restricts the product quality control effect and the intuitiveness of the display, and brings potential hidden dangers to the subsequent user experience. This invention improves the working mode of displaying and detecting the light transmittance of automotive films by utilizing the functions of a continuous film-moving component and a light transmittance display component. The specific benefits are as follows: Enhanced versatility: The continuous film feeding assembly can adapt to automotive films of different thicknesses and specifications by adjusting the clamping force, without the need to replace equipment or core components, reducing equipment investment and maintenance costs. It effectively solves the problems of poor compatibility and narrow adaptability of traditional equipment, and can meet the display and testing needs of various specifications of automotive films. Enhanced fixing and flattening effect: The continuous film conveying assembly fixes the automotive film through an adjustable clamping force, which not only ensures that the film surface is clamped and there is no displacement or shaking, but also smooths out the wrinkles on the film surface, ensuring the flatness of the automotive film during the rotation and conveying process, avoiding display deviations caused by film wrinkles and shaking, and reducing quality misjudgments caused by improper film fixing. Enhance the intuitiveness and practicality of the display: The light transmittance display component can provide a variety of lighting modes, and staff can directly observe the actual light transmittance effect of the continuously rotating car film in different scenarios (such as heat insulation and anti-glare under strong daylight, and visibility clarity under weak nightlight) with the naked eye, and intuitively compare the optical performance of the car film. Enhance quality control capabilities: The continuous film conveying module drives the automotive film to rotate and be transported dynamically throughout the entire process. The light transmittance display module can comprehensively scan the entire roll of automotive film, detect quality defects such as uneven light transmission and minor flaws in the film, eliminate potential hidden dangers in product quality control and subsequent use, and improve the quality stability of automotive film products.

[0016] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0017] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0018] Please see Figures 1 to 7 This invention provides a device for displaying the light transmittance of automotive film with an adjustable light source, comprising: a frame 1; two symmetrically arranged first support frames 2, each fixedly connected to the top of the frame 1, with one end of the uppermost first support frame 2 being inclined; a second support frame 3, fixedly connected to the frame 1 and located below the first support frame 2; a continuous film-moving assembly, mounted on the first support frame 2 and the second support frame 3, for driving the automotive film to rotate at a uniform speed; and a light transmittance display assembly, mounted on the frame 1.

[0019] Using the above method: When it is necessary to demonstrate the light transmittance of automotive film, the staff manually wraps the film around the continuous film-moving assembly and adjusts the clamping force of the assembly to ensure the film is clamped tightly and without wrinkles. Then, the continuous film-moving assembly rotates the film, which is continuously and uniformly transported from bottom to top under its traction. Once it enters the horizontal, straight film-moving section, the light transmittance demonstration assembly illuminates the film, allowing staff to directly observe the actual light transmittance of the continuously rotating film under different lighting conditions. This includes the heat insulation and anti-glare effects under strong daylight conditions and the visibility clarity under weak nightlight conditions, providing a direct comparison of the film's optical performance and thus demonstrating its light transmittance.

[0020] Furthermore, the continuous film-feeding assembly includes: two flattening rollers 4 rotatably connected to the first support frame 2 at the top, forming a horizontal and straight film-feeding section; one end of each flattening roller 4 is fixedly connected to a symmetrically arranged first synchronous wheel 5, and a first synchronous belt 6 is sleeved on the first synchronous wheel 5.

[0021] Furthermore, the first support frame 2 has three guide rollers 7 rotatably connected to one side of the inclined shape; the guide rollers 7 are located on one side of the flattening roller 4, and the guide rollers 7 are all placed at an incline. The first support frame 2 at the top is rotatably connected to a first pair of pressure rollers 8 below the flattening roller 4; a first slide rail 9 is provided on the first support frame below; a first slider 10 is slidably connected in the first slide rail 9, and a second pair of pressure rollers 11 is rotatably connected on the first slider 10. Both the first pair of pressure rollers 8 and the second pair of pressure rollers 11 are provided with patterns.

[0022] Furthermore, a unwinding roller 12 is rotatably connected to the second support frame 3; a first motor 13 is installed on one side of the frame 1, and a second synchronous pulley 14 is fixedly connected to the output end of the first motor 13 and one end of the unwinding roller 12, and a second synchronous belt 15 is sleeved on the second synchronous pulley 14.

[0023] Furthermore, the frame 1 is rotatably connected to one side of the flattening roller 4; a semi-circular guide rail 17 is fixedly connected to one side of the frame 16 on the frame 1, and one side of the frame 16 is slidably connected to the semi-circular guide rail 17. Two sets of smoothing wheels 18 are rotatably connected on the frame 16.

[0024] Furthermore, the two side walls of the frame 16 are rotatably connected to a first connecting rod 19; a telescopic rod 20 is slidably connected to the first connecting rod 19; a first fixing plate 21 is fixedly connected to the extended end of the telescopic rod 20; a spring 22 is installed between the first fixing plate 21 and the fixed end of the telescopic rod 20; and a limiting wheel 23 that can contact the vehicle film is rotatably connected to the first fixing plate 21.

[0025] Using the above scheme: In use, the operator fixes the entire roll of car film onto the unwinding roller 12 of the second support frame 3, extends the free end, and manually winds it sequentially around the first pair of pressure rollers 8, the second pair of pressure rollers 11, and the two flattening rollers 4, finally winding it around the three guide rollers 7 onto the unwinding roller 12. When adjusting the tension, the operator pushes the first slider 10 to slide within the first slide rail 9, causing the second pair of pressure rollers 11 to shift. Adjusting the pressure of the second pair of pressure rollers 11 in contact with the car film, the frame 16 rotates to a preset position on the frame 1 and the semi-circular guide rail 17. After the two sets of smoothing wheels 18 on the frame 16 contact the back of the car film, the frame 16 is fixed. Rotating the first connecting rod 19 causes the telescopic rod 20 to flip to a preset position, so that the two limiting wheels 23 are located on both sides of the car film, and the spring 22... Pushing the extension end of the telescopic rod 20 causes the first fixed plate 21 and the limiting wheel 23 to move to contact the car film for limiting. The output end of the first motor 13 rotates to drive the second synchronous wheel 14. Through the second synchronous belt 15, the other second synchronous wheel 14 drives the unwinding roller 12 to rotate and release the car film. At the same time, through the two first synchronous wheels 5 and the first synchronous belt 6, the two flattening rollers 4 rotate synchronously. Under the traction of the flattening roller 4 and the unwinding roller 12, the car film is conveyed continuously from bottom to top at a uniform speed. Two patterned pressure rollers and smoothing rollers 18 act on the car film. Through the action of the pressure rollers and smoothing rollers 18, the wrinkles and curling edges generated during the conveying of the car film are smoothed, and the micro bubbles on the film surface are eliminated to ensure that the film surface is flat. The flattening roller 4 flattens the car film, which is convenient for the subsequent light transmittance display operation of the car film.

[0026] It should be noted that: First, after the frame 16 rotates to the preset position, it can be fixed by a fixing structure, which is existing technology. Second, a motor can be installed on the top first support frame 2, with one end of one of the flattening rollers 4 fixed to the motor output end. The motor drives the flattening roller 4 to rotate, which cooperates with the unwinding roller 12 to make the car film rotate and move.

[0027] Furthermore, the light transmittance display component includes: an inclined frame 24 fixedly connected to one side of the frame 1; a second slider 25 slidably connected to the inclined frame 24; a tension spring 26 fixedly connected between the second slider 25 and the inclined frame 24; and a guide rod 27 fixedly connected to one side of the second slider 25.

[0028] Furthermore, a fixed base 28 is slidably connected to the guide rod 27, a rotating disk 29 is rotatably connected to the fixed base 28, and an adjustable light source module 30 symmetrically arranged vertically is fixedly connected to the rotating disk 29.

[0029] Using the above scheme: In use, according to the illumination angle of the adjustable light source module 30, the fixing base 28 is inserted into the guide rod 27 and pushed to the preset position. Through the action of the tension spring 26, the second slider 25 is pulled to slide on the tilting frame 24, thereby driving the adjustable light source module 30 to gradually approach the car film, so that it adjusts the distance between the adjustable light source and the car film. At the same time, through the action of the rotating disk 29, the adjustable light source module 30 is driven to rotate, thereby adjusting the horizontal or vertical illumination angle of the adjustable light source module 30. When the car film rotates at a constant speed, after passing through the illumination area of ​​the adjustable light source module 30, the adjustable light source module 30 emits light that passes through the car film. At this time, the staff can directly observe the actual light transmission effect of the continuously rotating car film under different lighting modes, such as the heat insulation and anti-glare effect in the strong light mode during the day, and the visibility clarity in the weak light mode at night. The optical performance of the car film can be directly compared, thereby demonstrating the light transmittance of the car film.

[0030] It should be noted that: First, the adjustable light source module 30 is an LED light panel. The brightness and color temperature of the LED light panel are continuously adjustable from 0 to 100%, and it has a one-button switch for preset modes, such as strong daylight, cloudy daylight, weak nightlight, tunnel, and oncoming high beams, which evenly illuminate the smooth automotive film surface to simulate various lighting environments during real driving. The LED light panel is existing technology, and a suitable one can be directly adopted. Second, after the second slider 25 moves to the preset position, it can also be fixed in the current position using a fixing structure. Third, the rotating disk 29 is existing technology.

[0031] Working principle of the invention: When it is necessary to demonstrate the light transmittance of the automotive film, the fixing seat 28 is inserted into the guide rod 27 according to the illumination angle of the adjustable light source module 30, and pushed to the preset position. Through the action of the tension spring 26, the second slider 25 is pulled to slide on the tilting frame 24, thereby causing the adjustable light source module 30 to gradually approach the automotive film, adjusting the distance between the adjustable light source and the film. Simultaneously, the adjustable light source module 30 can be rotated by the rotating disk 29, thereby adjusting the horizontal or vertical illumination angle of the adjustable light source module 30. The operator then fixes the entire roll of automotive film to the unwinding roller of the second support frame 3. On the unwinding roller 12, extend the free end and manually wind it around the first pair of pressure rollers 8, the second pair of pressure rollers 11, and the two flattening rollers 4 in sequence, and finally around the three guide rollers 7. When adjusting the tension, push the first slider 10 to slide in the first slide rail 9, which will drive the second pair of pressure rollers 11 to move. Adjust the pressure of the second pair of pressure rollers 11 in contact with the car film, and the frame 16 will rotate to the preset position on the frame 1 and the semi-circular guide rail 17. After the two sets of smoothing rollers 18 on the frame 16 contact the back of the car film, fix the frame 16. Rotate the first connecting rod 19 to drive the telescopic rod 20 to flip to the preset position, so that the two limit rollers 23 are in position. On both sides of the car film, springs 22 push the extension end of the telescopic rod 20, causing the first fixed plate 21 and the limiting wheel 23 to move to contact the car film for limiting. The output end of the first motor 13 rotates, driving the second synchronous wheel 14. The second synchronous belt 15 causes another second synchronous wheel 14 to drive the unwinding roller 12 to rotate and release the car film. At the same time, the two first synchronous wheels 5 and the first synchronous belt 6 cause the two flattening rollers 4 to rotate synchronously. Under the traction of the flattening roller 4 and the unwinding roller 12, the car film is conveyed continuously and uniformly from bottom to top. Two patterned pressure rollers and smoothing rollers 18 act on the car film, smoothing the car film through the action of the pressure rollers and smoothing rollers 18. Wrinkles and curling edges generated during the film conveying process are eliminated, and tiny air bubbles on the film surface are removed to ensure a smooth film surface. The flattening roller 4 flattens the car film, facilitating the subsequent light transmittance display operation. When the car film rotates at a constant speed, after passing through the irradiation area of ​​the adjustable light source module 30, the adjustable light source module 30 emits light that passes through the car film. At this time, the staff can directly observe the actual light transmittance effect of the continuously rotating car film under different lighting modes, such as the heat insulation and anti-glare effect under strong light mode during the day, and the visibility clarity under weak light mode at night. The optical performance of the car film can be directly compared to demonstrate the light transmittance of the car film.
