Method and device for testing light transmission of air conditioner panel

Abstract

The invention discloses a method and device for testing light transmission of an air conditioner panel. The method for testing light transmission comprises the steps that a light emitting element and a light sensing element are arranged at set positions on a production line, and an air conditioner panel is placed on a workbench of the production line; the air conditioner panel is enabled to stay between the light emitting element and the light sensing element when the air conditioner panel flows to the set positions along with the workbench; the light sensing element detects the illumination intensity of the current environment, and a recorded acquisition value is a taken as a first illumination intensity value; the light emitting element is electrified and emits light, the light sensing element detects the illumination intensity after light emitting, and a recoded acquisition value is taken as a second illumination intensity value; the light emitting element is turned off after acquisition is completed, and the flow of the production line is controlled; and a difference value acquired by subtracting the first illumination intensity value from the second illumination intensity value is enabled to be compared with a qualified illumination intensity range. According to the method for testing light transmission, the test efficiency can be improved by adopting the method to perform a light transmission test on the air conditioner panel.

Description

technical field [0001] The invention relates to the field of air conditioner testing equipment, in particular to a light transmission test method and device for an air conditioner panel. Background technique [0002] Most of the air-conditioning indoor units used in people's lives are equipped with photosensitive sensors. The photosensitive sensors are installed on the display panel of the air conditioner. The indoor light needs to pass through the panel before it can be detected by the photosensitive sensor. Therefore, the panel is required to have better light transmission. . But for the air conditioner, in order to ensure a good display and visual effect, the panel cannot be made too transparent, so it is necessary to control the light transmittance of the panel within a reasonable range. This requires a detection device to detect whether the light transmission of the panel is within the acceptable range during production or procurement. [0003] Factories around the wo...

AI Technical Summary

Problems solved by technology

Each panel must be manually installed with a display board and covered with a tooling cover. The whole process will take a certain amount of time through human observation of the data; Put on the buckle and remove it after the test, which not only affects the efficiency, but also has the risk of breaking the buckle

[0005] 2. There are random errors

When installing the display panel and the photosensitive cover, there are problems such as loose fit (if the display box and the panel are fixed with screws, the screws will not be screwed during measurement, and the display box is usually held down by hand), looseness during measurement, etc. In some cases, it is easy to cause errors in the measurement results, and sometimes it needs to be re-measured, which affects the efficiency

[0006] 3. The panel is tarnished or scratched

During the measurement process, manual operation may cause the panel to be scratched or stained
