Description

Technical Field

[0001] This utility model relates to the field of display screen testing technology, and in particular to a testing machine for LCM liquid crystal displays. Background Technology

[0002] As a core component of modern electronic devices, LCD screens are characterized by low power consumption, thinness, no radiation, and wide viewing angle. They are widely used in televisions, computers, mobile phones, industrial equipment, and other fields. Their performance stability and environmental adaptability directly affect the quality of end products.

[0003] Traditional testing equipment often uses fixed brackets or simple clamps to fix samples, which cannot flexibly adjust the angle and height of the display screen. This results in incomplete coverage of illumination testing and uneven simulation of temperature and humidity environments, making it difficult to accurately evaluate the performance of the display screen under different usage scenarios. Utility Model Content

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] A testing machine for LCM liquid crystal displays, such as Figures 1-6 As shown, the device includes a housing 1, an electric push rod 2, a mounting plate 4, a drive motor 5, a first gear 6, a mounting base 7, a second gear 8, a placement plate 9, a dual-axis motor 10, lead screws 11, clamping plates 13, and a testing assembly. The electric push rod 2 is located on the lower side of the housing 1. The piston of the electric push rod 2 is connected to the mounting plate 4, allowing the electric push rod 2 to drive the mounting plate 4 to move up and down. The drive motor 5 is mounted on the upper side of the mounting plate 4, and the output shaft of the drive motor 5 is connected to the first gear 6. A mounting base 7 is located at the center of the upper side of the mounting plate 4, and a second gear 8 is rotatably mounted on the mounting base 7. The first gear 6 and the second gear 8 mesh. A placement plate 9 is located on the upper side of the second gear 8. The placement plate 9 is circular, and a dual-axis motor 10 is located on the upper side of the placement plate 9. The two output shafts of the dual-axis motor 10 are respectively connected to two lead screws 11, with opposite thread directions. The two lead screws 11 are respectively threaded to two clamping plates 13. The testing assembly is located inside the housing 1 and can test the display screen's performance under temperature, humidity, and different brightness modes.

[0022] In use, the display screen to be tested is placed on the placement plate 9. The dual-axis motor 10 drives the lead screw 11 to rotate. The lead screw 11 drives the clamping plate 13 connected to it to move. Since the threads of the two lead screws 11 are opposite, the two clamping plates 13 will move closer to each other and clamp the display screen. The test component tests various performance of the display screen, such as the operating results under different temperature and humidity environments or after long-term strong light exposure. During the test, the height and angle of the display screen can be adjusted by the electric push rod 2 and the drive motor 5 to adapt to different test requirements.

[0023] like Figures 2-6As shown, the test components include a humidifier 15, a temperature controller 17, a temperature and humidity sensor 18, LED lights 19, a camera 20, and a control panel 21. The humidifier 15 and temperature controller 17 are located on the inner side wall of the chamber 1. The temperature and humidity sensor 18 is located on the upper side of the mounting plate 4. An array of LED lights 19 is located on the upper side of the inside of the chamber 1. The camera 20 is located in the middle of the upper side of the inside of the chamber 1. The control panel 21 is located on the outer side of the chamber 1. The humidifier 15, temperature controller 17, temperature and humidity sensor 18, LED lights 19, and camera 20 are all electrically connected to the control panel 21. The humidifier 15 inside the chamber 1 works with the temperature controller 17 to adjust the temperature and humidity inside the chamber through the control panel 21 to simulate different environmental conditions and test the performance of the display screen in extreme environments. The array of LED lights 19 on the top of the chamber 1 provides illumination with different brightness modes to simulate actual usage scenarios and test the performance of the display screen under strong light or long-term exposure. The temperature and humidity sensor 18 monitors environmental parameters in real time, and the camera 20 records the display effect of the display screen.

[0024] like Figure 5 and Figure 6 As shown, it also includes a dehumidifier 16. The dehumidifier 16 is provided on the inner side wall of the housing 1. The dehumidifier 16 is electrically connected to the control panel 21. The dehumidifier 16 works in conjunction with the humidifier 15 to achieve bidirectional humidity regulation (humidification / dehumidification), avoid humidity exceeding the standard due to single humidification, expand the controllable range of the test environment, and adapt to more complex test requirements.

[0025] like Figure 3 and Figure 4 As shown, it also includes a first guide rod 3 and a second guide rod 12. The first guide rod 3 is provided inside the housing 1. The mounting plate 4 is slidably connected to the first guide rod 3. The second guide rod 12 is provided on the lower side of the placement plate 9. Both clamping plates 13 are slidably connected to the second guide rod 12. The first guide rod 3 constrains the mounting plate 4 to move only in the vertical direction, ensuring the stability of the electric push rod 2 when it is raised and lowered, and preventing tilting or deviation. The second guide rod 12 guides the clamping plate 13 to slide precisely in the horizontal direction, avoiding rotation or lateral deviation of the clamping plate 13 when the lead screw 11 rotates, and ensuring the reliability of the clamping action.

[0026] like Figure 4 As shown, it also includes a soft pad 14. The two clamping plates 13 are provided with a soft pad 14 on one side opposite to each other to avoid excessive clamping force causing scratches on the surface of the display screen or structural damage, while providing cushioning to protect the edges of the display screen.

[0027] The number of teeth on the first gear 6 is less than the number of teeth on the second gear 8, achieving a speed reduction and torque increase effect. The drive motor 5 can drive the second gear 8 to rotate slowly and smoothly under a small torque, ensuring a smooth adjustment process for the angle of the placement plate 9 and avoiding screen shaking due to excessive speed.
