Embodiment 3

[0051] like Figure 6~7 As shown, the difference between the automatic temperature control tooling for optical-mechanical detection in this embodiment of the present invention and Embodiments 1 and 2 is that the temperature control module reads R / G / B / BP respectively through four DS18B20 temperature sensors. Based on the temperature of the backplane of the light source, the cooling fans corresponding to R / G / B / BP are controlled respectively based on the temperature, and then the exhaust air volume is controlled to control the temperature of the backplane of the light source transmitted on the copper block of the tooling, and finally the backplane of the light source is stabilized. Temperature purpose (for example: R temperature 52°C±3, G temperature 62°C±3, B temperature 58°C±3, BP temperature 65°C±3). In order to facilitate the operation of workers, indicator lights of different colors relative to the light source and a TFT liquid crystal temperature display are added to the de...

Description

technical field [0001] The invention relates to the field of optical-mechanical detection, in particular to an automatic temperature control tool for optical-mechanical detection and a use method. Background technique [0002] In the production process of the optical machine, it is necessary to test the performance of all aspects of the optical machine, and in the testing process, it is necessary to strictly control the temperature of the copper substrate of the optical machine LED light source (R light source, G light source, B light source, BP light source) within a certain range , if the temperature control is not good, it will cause the color cast of the light source, the color coordinates will be incorrect, and it may even cause the light source to burn out due to excessive temperature. Because the light effect, life and temperature of the LED chip light source are very closely related, and a reasonable working temperature can ensure that the LED light source can be use...
