Description

Technical Field

[0001] The utility model relates to the technical field of glass detection, and particularly relates to a light transmittance detection device for an anti-reflection organic glass for vehicles. Background Art

[0002] As more and more people start to use cars, which have become one of the essential tools for people's travel, people have put forward higher requirements for the performance of automotive parts. The same is true for glass, which is one of the automotive parts. Anti-reflection organic glass is a high molecular compound polymerized from methyl methacrylate, and anti-reflection organic glass has advantages such as good transparency, chemical stability, mechanical properties, and weather resistance. Before using anti-reflection organic glass, it is necessary to detect the light transmittance of anti-reflection organic glass.

[0003] At present, in the actual operation process of the anti-reflection organic glass light transmittance detection device, a box body shell is generally used to isolate external light sources. However, the box body shell surrounds and covers the detection table, and the box body shell is fixed. The anti-reflection organic glass to be detected can only be placed through the opening of the box body shell. Therefore, the size of the opening limits the size of the anti-reflection organic glass to be detected.

[0004] For this reason, we propose a light transmittance detection device for an anti-reflection organic glass for vehicles. Content of the Utility Model

The light-shielding component covers the detection area of the light transmittance of the organic glass, avoiding interference from external environmental light on the measurement of the illumination brightness. The stretching component controls the spring telescopic rod to be compressed, thereby driving the light-shielding component to contract upward. When the light-shielding component is no longer located around the base, the light-shielding component will not affect the placement of the organic glass, and it is suitable for placing organic glass of different sizes.

[0006] The utility model solves the above technical problems through the following technical solutions. The utility model includes:

[0029] The following further elaborates on the above and other technical features and advantages of the present utility model with reference to the accompanying drawings.

[0030] Embodiment 1

[0031] This embodiment provides a technical solution: a detection device for the light transmittance of an anti-reflective plexiglass for vehicles, as Figures 1 to 4As shown in the figure, it includes a base 1. A light-transmitting opening 11 is provided in the center of the top surface of the base 1. An illuminometer 12 is provided inside the base 1 and below the light-transmitting opening 11. A top base 3 is provided above the base 1. A lighting lamp 10 is provided at the bottom of the top base 3 directly above the light-transmitting opening 11. The plexiglass is placed on the top surface of the base 1 and covers above the light-transmitting opening 11. The lighting lamp 10 emits light towards the light-transmitting opening 11. The light penetrates the plexiglass and is received by the illuminometer 12. The illuminometer 12 measures the illumination brightness of the light after penetrating the plexiglass, and compares it with the brightness of the light originally emitted by the lighting lamp 10, so as to calculate the light transmittance of the plexiglass;

[0032] A light-shielding component that can be telescopically moved up and down is connected to the bottom of the top base 3, and the light-shielding component covers the lighting lamp 10 to prevent the ambient light from interfering with the measurement of the illumination brightness, and the up-and-down telescopic movement of the light-shielding component will not interfere with the placement of the plexiglass;

[0033] A spring telescopic rod 5 is vertically connected to the bottom edge of the bottom surface of the top base 3. The bottom end of the spring telescopic rod 5 is connected to the side wall of the bottom end of the light-shielding component. The bottom of the light-shielding component is in contact with the top surface of the base 1. A stretching component for controlling the telescopic movement of the spring telescopic rod 5 is provided at the top of the top base 3. When the spring telescopic rod 5 is not compressed under normal conditions, the light-shielding component is stretched, so as to cover the detection area of the light transmittance of the plexiglass and prevent the ambient light from interfering with the measurement of the illumination brightness. The stretching component controls the spring telescopic rod 5 to be compressed, so as to drive the light-shielding component to contract upwards. The light-shielding component is no longer around the base 1, so the light-shielding component will not affect the placement of the plexiglass and is suitable for the placement of plexiglass of different sizes.

[0034] Embodiment 2

[0035] This embodiment is a further optimization based on Embodiment 1. The same parts as the foregoing technical solutions will not be repeated here. As Figures 1 to 4 shown in the figure, in order to better implement the present invention, the following setting method is particularly adopted: A detection table 2 is provided in the center of the top of the base 1. The light-transmitting opening 11 penetrates through the detection table 2. The lower end of the light-shielding component covers the detection table 2, so that the coverage of the detection area of the light transmittance of the plexiglass by the light-shielding component is more comprehensive, and the interference of the ambient light is further reduced.

[0036] Furthermore, the light-shielding component includes a plurality of light-shielding cover cylinders 6 that are sequentially movably sleeved from top to bottom, realizing the up-and-down telescopic movement of the light-shielding component and covering the detection area of the light transmittance of the plexiglass to prevent the interference of the ambient light.

The top of the light-shielding corrugated cylinder 7 is connected to the bottom surface of the top seat 3. The light-shielding corrugated cylinder 7 can be telescopically extended and retracted up and down, and can block the gaps between adjacent light-shielding hood cylinders 6, further improving the light-shielding degree of the light-shielding component for the detection area of the light transmittance of the machine glass and avoiding the interference of external ambient light.

[0038] Furthermore, connection pads 9 are connected to both the inner and outer walls of the bottom of the lowermost light-shielding hood cylinder 6. The bottom surface of the connection pad 9 is flush with the bottom surface of the light-shielding hood cylinder 6. The bottom ends of the spring telescopic rod 5 and the light-shielding corrugated cylinder 7 are vertically connected to the top surface of the connection pad 9, which is beneficial to the up and down telescopic movement of the spring telescopic rod 5 and the light-shielding corrugated cylinder 7.

[0039] Furthermore, limiting blocks 8 are connected to both the inner side wall of the lower end of the light-shielding hood cylinder 6 and the outer side wall of the upper end of the adjacent light-shielding hood cylinder 6, and the two limiting blocks 8 are engaged with each other to prevent the separation between adjacent light-shielding hood cylinders 6.

The output signal of the illuminometer 12 is fed back to the display screen 13. The illuminometer 12 measures the light brightness and outputs it to the display screen 13 for visual display, which is beneficial to understanding the light transmittance of the plexiglass in real time.

[0042] Furthermore, a bracket 4 is vertically connected between the bottom of the rear end of the top seat 3 and the top of the rear end of the base 1, forming a "C" - shaped contour. The connection between the top seat 3 and the base 1 is stable, and the appearance is neat, which is convenient for carrying and handling.

[0043] Furthermore, the stretching component includes a cable 14, a bidirectional motor 15 and a wire winding disc 16. The inside of the top seat 3 is hollow and the wire winding disc 16 is installed therein. The cable 14 is wound around the outer surface of the wire winding disc 16, and the other end of the cable 14 is connected to the bottom end of the spring telescopic rod 5. The cable 14 is hidden inside the cable 14. The bidirectional motor 15 is installed on the top of the top seat 3 and the output shaft is connected to the axis of the wire winding disc 16. The bidirectional motor 15 drives the wire winding disc 16 to rotate so as to wind up the cable 14.
