Description

Technical Field

[0001] This utility model relates to the field of display module technology, and in particular to a testing device for environmental testing equipment. Background Technology

[0002] During the R&D phase, LCD modules typically undergo accelerated aging tests in environmental testing equipment to expose their potential risks. To achieve the illuminated state of the display module in the reliability testing equipment, the illumination board and the module under test are usually placed inside the equipment. Inside, the illumination board outputs the corresponding voltage and control signals to the display module via adapter cables, thus activating the module. The power required by the illumination board is transmitted from outside the equipment to inside via appropriate wires. Please refer to [reference needed]. Figure 1 The existing aging rack includes a frame 100 for supporting the module under test 300 and a lighting plate 200 for illuminating the display module. The lighting plate 200 is located below the frame 100 and enters the test equipment along with the frame 100 and the module under test 300. Due to the lack of necessary protection, the lighting plate 200 will be affected by the test environment inside the test equipment. Therefore, while the LCD display module is being aged by environmental testing, the lighting plate 200 is also being aged, resulting in a sharp reduction in the lifespan of the lighting plate 200 and an increase in the corresponding test costs.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a testing device for environmental testing equipment.

[0005] The technical solution of this utility model is as follows: This utility model provides a testing device for environmental testing equipment, including: a frame for supporting the module under test and a lighting plate for illuminating the module under test. The frame is provided with a accommodating cavity that is isolated from the internal air of the environmental reliability testing equipment. The lighting plate is disposed in the accommodating cavity. The accommodating cavity is provided with an air inlet and an air outlet. The air inlet and the air outlet are respectively connected to the outside of the environmental reliability testing equipment through an air inlet channel and an air outlet channel. The accommodating cavity is also provided with a number of cable holes for leading out the cables connected to the lighting plate from the accommodating cavity.

[0006] Furthermore, the solution also includes a cover plate, which is disposed on the frame to enable opening and closing of the receiving cavity.

[0007] Furthermore, the solution also includes a latch, which is disposed on the frame to lock the cover plate.

[0008] Furthermore, the solution also includes a waterproof sealing strip, which is disposed between the cover plate and the frame.

[0009] Furthermore, the cable hole is provided with a buffer material to ensure the airtightness of the cavity when the cable is led out of the cavity.

[0010] Furthermore, an exhaust device is provided at the exhaust port or exhaust passage.

[0011] Furthermore, a temperature sensing unit is provided on the lighting plate, the lighting plate is electrically connected to the exhaust device, and the working state of the exhaust device is controlled according to the temperature detected by the temperature sensing unit.

[0012] By adopting the above solution, the beneficial effects of this utility model are: avoiding the impact of extreme environments such as high temperature and high humidity inside environmental testing equipment on the lighting board, improving the service life of the lighting board in the aging equipment, and reducing testing costs.

[0014] Figure 2 This is a side cross-sectional view of an embodiment of the present invention. Detailed Implementation

[0015] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Please see Figure 2 In this embodiment, the present invention provides a testing device for environmental testing equipment, comprising: a frame 1 for supporting a module under test 300 and a lighting plate 2 for illuminating the module under test 300. The frame 1 is provided with a accommodating cavity isolated from the internal air of the environmental reliability testing equipment. The lighting plate 2 is disposed in the accommodating cavity. The accommodating cavity is provided with an air inlet 6 and an exhaust outlet 8. The air inlet 6 and the exhaust outlet 8 are respectively connected to the outside of the environmental reliability testing equipment through an air inlet channel 7 and an exhaust outlet channel 9. Through the cooperation of the air inlet channel 7 and the exhaust outlet channel 9, external air can be allowed to enter the accommodating cavity to cool the lighting plate 2. The cable electrically connected to the module under test 300 is led out from the cable hole on the accommodating cavity. The buffer material provided at the cable hole can ensure the airtightness of the accommodating cavity and prevent the high temperature and high humidity environment from affecting the life of the lighting plate 2.

[0017] Furthermore, the solution also includes a cover plate 3, a buckle 5, and a waterproof sealing strip 4. The cover plate 3 is installed on the frame 1 to open and close the receiving cavity. The buckle 5 is installed on the frame 1 to lock the cover plate 3. The waterproof sealing strip 4 is installed between the cover plate 3 and the frame 1 to achieve a waterproof seal and prevent high-temperature air, water vapor, etc. from entering the receiving cavity.

[0018] Furthermore, an exhaust device (such as a fan) is provided at the exhaust port 8. A temperature sensing unit is provided on the lighting plate 2. The lighting plate 2 is electrically connected to the exhaust device and controls the working state of the exhaust device according to the temperature detected by the temperature sensing unit. For example, when the temperature is high, the exhaust device is controlled to perform operations such as air exchange and increase the air exchange speed, so as to reduce the temperature inside the accommodating cavity.

[0019] In summary, the beneficial effects of this solution are: avoiding the impact of extreme environments such as high temperature and high humidity inside environmental testing equipment on the lighting board, extending the service life of the lighting board in aging equipment, and reducing testing costs.
