Description

Technical Field

[0001] The utility model relates to a detection tool, and more specifically, to a film clarity detection tool. Background Art

[0002] With the growing popularity of window film, it's now a common practice for both cars and buildings. Window film, through the application of various functional materials, can provide insulation, heat preservation, safety, explosion protection, UV protection, glare reduction, privacy, high temperature resistance, and fire resistance. These advantages have earned it a growing popularity and acclaim, making it a widespread fixture in everyday life. However, it's not without its drawbacks. Using inferior film can introduce new flaws, the most direct of which is visual impairment. With inferior film, objects seen through the glass become blurry and unclear, especially in bright sunlight or on sunny days. Therefore, a quick and easy way to compare and determine the clarity of films is urgently needed. This is especially crucial for manufacturing lines, where timely inspection and control during the manufacturing process ensure product quality. Summary of the Invention

[0003] The utility model overcomes the shortcomings of existing film clarity detection that is relatively subjective and difficult to quantify, and provides a film clarity detection tool, which can improve the standardization of detection, increase the lighting angle, and meet the coverage of various situations.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A film clarity detection tool includes a positioning frame and a detection bracket, the positioning frame is provided with an open window for exposing the film, the detection bracket is placed with a detection plate, the detection plate is facing the open window, the positioning frame is provided with a light source and a reflector, the light source is arranged on one side of the positioning frame, and the reflector is arranged on the other side of the positioning frame, on a plane perpendicular to the open window, the projections of the light source and the reflector are located on both sides of the positioning frame, the light source and the reflector are respectively rotatably connected to the positioning frame, and various lighting angles are simulated by adjusting the angles of the light source and the reflector.

[0006] The positioning frame is used to position the film to be tested, and the film is exposed through the open window on the positioning frame so that light can pass through the film. The detection bracket places a detection board with a regular pattern on it. The detection board and the open window face each other directly to avoid the problem of different distances and light reflection caused by angles. The light generated by the light source is directly or detected on the back of the film to illuminate the film and simulate the use environment. Since light does not always shine on the film at a specific angle in reality, this application increases the latitude of film clarity detection and improves the coverage of various situations by additionally setting up reflectors to cooperate with the light source to generate light in all directions, so as to maximize the approximation to various real environments.

[0007] Preferably, the positioning frame has a slot with a side opening, and the film can be inserted from the side opening. The film is inserted through the slot to achieve positioning of the film.

[0008] Preferably, the surface of the test board is provided with a dot gauge and / or a line gauge, which is used to judge the clarity of the film. Since the dot gauge and the line gauge meet the specifications, the objectivity of the test can be improved.

[0009] Preferably, a support frame is further included, and the support frame is fixedly connected to the positioning frame and the detection bracket respectively.

[0010] Preferably, the light source and the reflector are connected to the positioning frame via an adjustable rod, wherein the adjustable rod includes a first rod body and a second rod body, and the first rod body and the second rod body are hingedly connected. The light source and the reflector are hinged via the adjustable rod to meet the deflection of the light source and the reflector relative to the film application angle.

[0011] Preferably, the light source is a laser light source.

[0012] Preferably, the adjustable rod is provided with an angle sensor for detecting the angle between the first rod body and the second rod body, the angle sensor being electrically connected to a controller. The angle sensor is connected to the controller to record observation results at various representative angles, thereby simplifying detection complexity.

[0025] Example:

[0026] A film 9 clarity detection tool, reference Figure 1 As shown, it includes a positioning frame 1 and a detection bracket 2.

[0027] The positioning frame 1 is provided with an opening window 3 for exposing the film 9. The positioning frame 1 has a slot with a side opening, and the film 9 can be inserted from the side opening. The film 9 is inserted through the slot to achieve positioning of the film 9.

[0028] A test plate 4 is placed on the test bracket 2, facing the open window 3. A dot gauge and / or line gauge are provided on the surface of the test plate 4. These dot gauges and line gauges are used to determine the clarity of the film 9. Since these dot gauges and line gauges meet specifications, the objectivity of the test can be improved.

[0029] It also includes a support frame 7, which is fixedly connected to the positioning frame 1 and the detection bracket 2 respectively.

[0030] In a further embodiment, the adjustable rod 8 is provided with an angle sensor for detecting the angle between the first and second rods, and the angle sensor is electrically connected to a controller. The angle sensor is connected to the controller to record observation results at various representative angles, thereby simplifying detection complexity.

[0031] The positioning frame 1 is provided with a light source 5 and a reflector 6. The light source 5 is arranged on one side of the positioning frame 1, and the reflector 6 is arranged on the other side of the positioning frame 1. The light source 5 and the reflector 6 are connected to the positioning frame 1 through an adjustable rod 8. The adjustable rod 8 includes a first rod body and a second rod body, and the first rod body and the second rod body are hingedly connected. The light source 5 and the reflector 6 are hinged by the adjustable rod 8 to meet the deflection angle of the light source 5 and the reflector 6 relative to the film 9. The first rod body is connected to the light source 5 or the reflector 6, and the second rod body is fixedly connected to the positioning frame 1. Figure 2 Point a in the middle simulates light coming from the left, point b simulates light coming from the right, and point c simulates light coming from all directions.

[0032] The light source 5 is a strong white light source 5, and in some embodiments, a laser light source 5, but the present invention is not limited thereto. Those skilled in the art can configure the light source 5 according to actual positioning requirements, for example, a bulb light source 5. The illumination of the light source 5 is ≥10,000 lux.

[0033] On a plane perpendicular to the open window 3, the projections of the light source 5 and the reflector 6 are located on both sides of the positioning frame 1. The light source 5 and the reflector 6 are respectively rotatably connected to the positioning frame 1, and various lighting angles are simulated by adjusting the angles of the light source 5 and the reflector 6.

[0034] The positioning frame 1 is used to position the film 9 to be tested, and the film 9 is exposed through the open window 3 on the positioning frame 1, so that light can pass through the film 9. The detection bracket 2 places the detection board 4, which has a regular pattern on it. The direct view of the detection board 4 and the open window 3 avoids the problem of different distances and light reflection caused by angles. The light generated by the light source 5 directly or in a detection manner is irradiated on the back of the film 9 to illuminate the film 9 and simulate the use environment. Since light does not always shine on the film 9 at a specific angle in reality, the present application increases the latitude of the clarity detection of the film 9 by additionally setting a reflector 6 and cooperating with the light source 5 to generate light in all directions, thereby increasing the coverage of various situations and maximizing the approximation to various real environments.

[0035] The testing steps include:

[0036] Insert the film 9 into the positioning frame 1;
