The invention relates to the technical field of processing of automobile lamps, in particular to a device for inspecting the antifogging effect of a lampshade of an automobile lamp. The device for inspecting the antifogging effect of the lampshade of the automobile lamp comprises a box which contains liquid, wherein a heating device for heating the liquid and a temperature sensor for detecting thetemperature of liquid are arranged in the box; the box is provided with a temperature control device; the temperature control device is connected with the heating device; the temperature sensor transmits signals to the temperature control device; the box is provided with a testing opening for diffusion of steam; the lampshade of the automobile lamp is arranged above the testing opening; and the lampshade of the automobile lamp is placed downwards along the inner surface. The effect of the antifogging coating of the lampshade of the automobile lamp can be inspected, particularly, different antifogging coatings can be inspected, or whether different spraying processes affect the effect of the antifogging coating or not can be inspected, and fogging effect, fogging time and the like of the lampshade of the automobile lamp under steam at different temperatures can be detected.
Description
technical field [0001] The invention relates to the technical field of automobile lamp processing, in particular to a device for testing the anti-fog effect of lampshades of automobile lamps. Background technique [0002] At present, many headlamps and front fog lamps in the automotive industry have sprayed anti-fog paint on the inner surface of the lampshade to prevent the generation of fog in order to avoid the problem of fog caused by the headlights being exposed to rain. [0003] Anti-fog coatings may have different degrees of failure under different environmental influences. How to better measure and judge the failure degree of anti-fog coatings requires this device to judge; which effect of different anti-fog coatings and whether different spraying processes have an impact on the effect of anti-fog coatings, etc. All of the above require a device that can accurately measure the anti-fog effect. Contents of the invention [0004] In order to solve the defect that the...
