Therefore, it is not possible to detect the sheet-like light-guiding film well, the efficiency is low and it is easy to affect the quality of the light-guiding film. Utility Model Content

[0004] The main purpose of the utility model is to provide a light guide film lighting detection device, aiming to realize rapid detection of a sheet of light guide film.

[0005] To achieve the above-mentioned purpose, the utility model proposes a light-guiding film lighting detection device, including a base and a detection plate, one side of the base and one side of the detection plate are rotatably connected, a detection seat is connected to the bottom of the detection plate, a detection groove is provided at the upper end of the detection seat, a detection lamp is embedded at the bottom of the detection groove, and the detection plate is provided with a plurality of limit strips above the detection groove to divide the detection groove into a plurality of detection stations.

[0012] Basic principles of light guide film lighting detection:

[0013] Mainly based on optical phenomena such as reflection, refraction, scattering and transmission of light, the differences in various areas of the light-guiding film are visually compared. By observing the performance of the light-guiding film in the lit state, its luminous uniformity, color consistency and other properties can be evaluated. At the same time, by measuring the performance changes of the light-guiding film in different environments, its temperature resistance, environmental adaptability and other characteristics can be evaluated.

[0014] Reflection and refraction of light: The surface of the light-guiding film has specific microstructures that can reflect light from one side of the film to the other. By adjusting the shape and size of the microstructure, directional reflection and refraction of light can be achieved, thereby controlling the propagation direction of light.

[0015] Light scattering and transmission: The microstructure in the light guide film also has the function of scattering and transmitting light. Through scattering, the light can be evenly dispersed in all directions to increase the uniformity of the light. Transmission allows light to pass through the light guide film to achieve better lighting effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0025] The utility model provides a light guide film lighting detection device.

[0026] In the embodiment of the utility model, the light guide film 3 lighting detection device, such as Figure 1 or Figure 4 As shown, it includes a base 1 and a detection plate 2, one side of the base 1 and the other side of the detection plate 2 are connected with a flip assembly so that the two are rotatably connected and can be flipped at any angle to adjust the angle and height of the light guide film 3 placed on the detection plate 2 until it is the most suitable position for inspection, wherein the flip assembly includes two end fixing blocks 11 arranged on one side of the base 1 and a rotating rod 12 inserted between the two fixing blocks 11, a rotating part 21 is provided on one side of the detection plate 2, the rotating part 21 is embedded between the two fixing blocks 11 and the rotating shaft passes through the rotating part 21 so that the detection plate 2 rotates around the base 1, and another A plurality of inspection stations 7 are provided near one side of the outer inspection plate 2 and the base 1. The inspection station 7 is composed of an L-shaped inspection seat 4 provided at the bottom of the inspection plate 2. A plurality of vertically downward limiting strips 5 are provided above the L-shaped inspection seat 4. A concave inspection station 7 is formed between every two limiting strips 5 and the inspection seat 4. An inspection light 8 is provided at the bottom of each inspection station 7. Through the plurality of inspection stations 7 on the inspection plate 2, the light-guiding film 3 can be quickly placed on the inspection station 7 and fixed, so that the light-guiding film 3 can be quickly inspected by the inspection light 8 at the bottom of the station.

[0027] Preferably, a detection seat 4 is connected to the bottom of the detection station 7, a detection groove 42 is provided at the upper end of the detection seat 4, and a detection lamp 8 is embedded in the bottom of the detection groove 42. The light guide film 3 is inserted into the detection groove 42 and the detection light 8 illuminates the side of the light guide film 3 for detection. In addition, the detection plate 2 is provided with a plurality of limit bars 5 above the detection groove 42 to divide the detection groove 42 into a plurality of detection stations 7. The limit bars 5 can be arranged vertically with respect to the detection seat 4, or can be arranged at an angle, so that a detection station 7 for placing the light guide film 3 is formed between the detection seat 4 and the two limit bars 5, and a plurality of light guide films 3 can be detected at the same time.

[0028] Furthermore, the upper ends of the two limiting strips 5 on the opposite sides are provided with beveled portions, which play a guiding role, making it easier to place the light-guiding film 3 into the detection groove 42, thereby increasing the detection efficiency, and the beveled portion can be an opening portion formed by a straight line cut at a certain angle to the limiting strip 5, or it can be a trumpet-shaped opening portion cut in an arc shape. When placing the light-guiding film 3, it is easy to misplace the position, and the beveled portion can increase a certain fault tolerance rate, thereby achieving rapid placement of the light-guiding film 3.

[0029] Alternatively, if Figure 2 As shown, when the detection plate 2 is rotated to a certain angle, the light guide film 3 is easy to flip over and fall from the detection station 7, so a limit plate 41 is provided on the side of the detection seat 4 away from the detection plate 2, and a detection groove 42 for inserting the light guide plate is formed between the limit plate 41 and the detection plate 2. The light guide film 3 is clamped by the limit plate 41. In addition, the detection lamp 8 is arranged at the bottom of the detection groove 42. In this way, the limit plate 41 can also block the light, so that the light will not directly hit the eyes of the detection personnel above, avoiding long-term use to cause damage to the eyes of the detection personnel.

[0030] Preferably, if Figure 3 As shown, a reflector 81 is provided at the upper end of the detection lamp 8, which converts the light diffused in all directions by the detection lamp 8 into parallel light and makes the light concentrated on the light-guiding film 3. At the same time, it also plays a role in protecting the eyes of the detection personnel, so that the light will not directly hit the eyes of the detection personnel above, avoiding long-term use to cause damage to the eyes of the detection personnel.

[0031] Optionally, the detection lamp 8 can be an incandescent lamp or an LED lamp, and the light source is bright and soft and does not damage the glasses.

[0032] Optionally, the detection light 8 is a long LED light strip, so that the light irradiated onto the light-guiding film 3 is more uniform. Each part is illuminated by the detection light 8 to prevent the light-guiding film 3 from showing local differences due to uneven light illumination, which may cause misjudgment by the inspectors and affect the product yield.

[0033] Optionally, a tightening knob 6 is screwed onto one end of the rotating rod 12 , and when the detection plate 2 is adjusted to a suitable position, the position is fixed by tightening the tightening knob 6 .

[0034] Optionally, a reflector 9 is provided on the opposite side of the detection plate 2 and the detection light 8. Since the detection light 8 only illuminates one side of the light-guiding film 3, the light on the side of the light-guiding film 3 away from the detection light 8 will be relatively weak. The reflector can reflect the light scattered from the light-guiding film 3 back to increase the brightness in the detection station 7. At the same time, it also plays a role in protecting the eyes of the detection personnel, so that the light will not directly shine into the eyes of the detection personnel above, and prevent the light from being radiated out to affect the work of other positions.

[0035] Optionally, the detection device is a fixed detection device, and a connection wire is provided on one side of the base 1, and is powered by an external power supply.

[0036] Preferably, a storage battery is provided on the base 1, and a charging port and a switch are provided on one side of the base 1. The storage battery and the charging port, the quick switch and the detection light 8 are electrically connected, so that the detection device can be moved along without being restricted by space.

[0037] Optionally, the flip assembly connected between the detection plate 2 and the base 1 includes two layers of plywood, a first rotating shaft and a second rotating shaft that move through the plywood respectively, a first elastic rotating wheel coaxially fixed with the first rotating shaft and located in the plywood, a second elastic rotating wheel coaxially fixed with the second rotating shaft and located in the plywood, and a circular locking wheel arranged between the first elastic rotating wheel and the second elastic rotating wheel, the circular locking wheel is fixed in the two plywood, and the outer rings of the first elastic rotating wheel and the second elastic rotating wheel are respectively provided with a recess that can cooperate and engage with the circular locking wheel. When the first rotating shaft rotates, the outer ring of the first elastic rotating wheel abuts against the circular locking wheel, and the first rotating shaft can stop at any angle under the elastic action of the first elastic rotating wheel itself. Similarly, the second rotating shaft can also stop at any angle position by relying on the cooperation between the second elastic rotating wheel and the circular locking wheel.

[0038] The two ends of the first rotating shaft are fixed to the bottom of the detection plate 2, and the two ends of the second rotating shaft are fixed to the top of the base 1. When the detection plate 2 and the base 1 are closed, the recesses of the first elastic rotating wheel and the second elastic rotating wheel are both opened upward, and the recess of the second elastic rotating wheel is engaged with the circular locking wheel; the detection plate 2 is rotated, and the recess of the first elastic rotating wheel rotates toward the circular locking wheel; when the recess of the first elastic rotating wheel rotates downward to engage with the circular locking wheel, the detection plate 2 and the base 1 are in a state of 180 degrees of flat unfolding, at which time the recesses of the first elastic rotating wheel and the second elastic rotating wheel are engaged with the circular locking wheel; the keyboard is rotated again, and the recess of the second elastic rotating wheel rotates out from the engaging position with the circular locking wheel; when the recess of the second elastic rotating wheel rotates downward to the same opening direction as the recess of the first elastic rotating wheel, the detection plate 2 and the base 1 are in a state of 360 degrees of reverse folding, at which time the recesses of the second elastic rotating wheel and the first elastic rotating wheel are both opened downward.
