Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal screen detection, and in particular to a detection device for a TFT liquid crystal screen. Background Art

[0002] TFT LCD screen is an active matrix liquid crystal display that uses thin film transistors (TFT) to drive each liquid crystal pixel. TFT LCD screen has the characteristics of high speed, high brightness and high contrast, and can provide high-quality image display effects. TFT LCD screen has a wide range of applications, covering multiple fields, mainly including the following aspects: consumer electronics, medical equipment, industrial automation, automotive electronics and other fields. At the same time, the production of TFT LCD screens usually requires testing of the appearance, display performance, electrical performance, menu functions, reliability, etc. of TFT LCD screens.

[0003] Reliability testing mainly includes the impact of vibration on TFT LCD screens. At present, during testing, TFT LCD screens are usually placed directly on vibration equipment or clamped on both sides of the TFT LCD screen by a clamping plate for vibration testing. The testing method is single and cannot be simulated according to the actual usage, resulting in reduced reliability testing effect. For example, when the TFT LCD screen is used, the four sides are sometimes embedded in the inner side of the device. When the hardness of the TFT LCD screen and the embedded object is very different, vibration may cause problems. For example, the object material is hard, such as metal material, while the TFT LCD screen is relatively brittle. During the vibration process, hard material objects may be easier to maintain their shape, while the TFT LCD screen is more susceptible to impact force. Hard material objects may also generate a large extrusion force on the edge of the TFT LCD screen due to inertia and other factors during vibration, which may cause impact in severe cases. At the same time, in some industrial production sites or transportation vehicles, strong vibration may increase the interaction force between the object and the TFT LCD screen, causing the object to impact the edge of the TFT LCD screen. And because TFT LCD screens are used in a wide range of environments, they are also susceptible to impacts from external objects when vibrating. The display screen is embedded in an object and vibrates: in addition to its own inertia force, it is also subject to squeezing force and friction force from the object. The contact part between the object and the display screen will produce interaction force. The magnitude and direction of these forces will continue to change with the change of vibration. Therefore, vibration will also affect the impact, thereby affecting the reliability detection of the TFT LCD screen. The existing vibration equipment cannot impact the panel and sides of the TFT LCD screen in different directions when the TFT LCD screen vibrates, which will also lead to a reduction in the reliability detection effect. Therefore, a detection device for TFT LCD screen is proposed to address the above problems. Summary of the invention

At the same time, the first electric telescopic rod 103, the second electric telescopic rod 114, the third electric telescopic rod 116, the fourth electric telescopic rod 118, the fifth electric telescopic rod 217, and the sixth electric telescopic rod 223 can be replaced by hydraulic rods or cylinders according to actual usage.

[0044] Working process: when the TFT LCD screen 6 needs to be in an embedded state, a first clamping plate 109 of a suitable width is selected according to the width of the TFT LCD screen 6 of different specifications, so that the first motor 104 rotates with the fixed cylinder 106, and then the fixed cylinder 106 rotates with the rotating cylinder 110, and then the rotating cylinder 110 rotates with the first clamping plate 109 through the first guide shaft 107, until the first clamping plate 109 of a suitable length is on one side of the TFT LCD screen 6, and the first clamping plate 109 of a suitable length is also on one side of the first electric telescopic rod 103, and the first electric telescopic rod 103 can push the corresponding first clamping plate 109 to clamp the TFT LCD screen 6 together, and the second electric telescopic rod 114 clamps the third clamping plate 119 with the TFT LCD screen 6 together, and the fourth electric telescopic rod 114 clamps the third clamping plate 119 with the TFT LCD screen 6 together. The rod 118 holds the TFT LCD screen 6 with the second clamping plate 112, and the first clamping plate 109, the second clamping plate 112 and the third clamping plate 119 can wrap all around the TFT LCD screen 6, so as to simulate the scene when the TFT LCD screen 6 is embedded in the device. Then the vibrator body 4 can vibrate with the TFT LCD screen 6 through the placement plate 401 and the support shell 3. The vibration of the vibrator body 4 can simulate the degree of influence of vibration when the TFT LCD screen 6 is embedded in the device, so as to compare with the degree of influence of vibration when the TFT LCD screen 6 is not embedded in the device, thereby providing more comprehensive and accurate detection data, improving the effect of reliability detection of the TFT LCD screen 6, and providing more valuable data for subsequent optimization and improvement of the reliability of the TFT LCD screen 6. When the TFT liquid crystal screen 6 needs to be impact-detected at the edge during vibration, the third electric telescopic rod 116 rotates the flap 117 clockwise, and the flap 117 rotates together with the second clamping plate 112 through the fourth electric telescopic rod 118, so that the second clamping plate 112 rotates to one side of the supporting shell 3, ensuring that the second clamping plate 112 does not affect the normal impact of the impact block 219 on the edge of the TFT liquid crystal screen 6, and the second clamping plate 112 can be clamped normally with the TFT liquid crystal screen 6 through the fourth electric telescopic rod 118, and then the fourth motor 222 rotates the second gear 220 clockwise, and then the second gear 220 stretches the second spring 218 through the bar rack 216 and the moving plate 215, so that the second spring 218 is rotated to the side of the supporting shell 3. The spring 218 is at a suitable extension length, at which time the impact block 219 is separated from the edge of the TFT liquid crystal screen 6, and then the sixth electric telescopic rod 223 quickly separates the second gear 220 from the bar rack 216 through the fixing frame 221, so that the second gear 220 releases the restriction on the bar rack 216, and then the second spring 218 moves with the moving plate 215; and when the second spring 218 is in a natural state, at this time, the teeth of the second gear 220 move upward and can mesh with the teeth of the bar rack 216, thereby ensuring the normal meshing and separation of the second gear 220 and the bar rack 216, without the need to manually move the bar rack 216, ensuring that the impact test can be successfully completed when the TFT liquid crystal screen 6 vibrates; When the impact angle of the impact block 219 in the horizontal direction needs to be changed, the second motor 201 is used to rotate the base 204, and then the base 204 is used to rotate the impact block 219 with the vertical center line of the second motor 201 as the axis through the support block 205, the arc guide rail 206, the slider 209, the support frame 213, and the fifth electric telescopic rod 217 until the impact block 219 is at a suitable impact angle in the horizontal direction, so as to simulate the external force impacts at different angles on the TFT LCD screen 6 in actual use; When the impact angle of the impact block 219 in the longitudinal direction needs to be changed, the third motor 211 is made to roll along the arc-shaped rack 207 with the first gear 212, and the slider 209 is also made to slide along the arc-shaped rack 207, so that the slider 209 rotates around the center of the arc-shaped rack 207 with the impact block 219 through the support frame 213 and the fifth electric telescopic rod 217 until the impact block 219 is at a suitable impact angle in the longitudinal direction, thereby simulating external force impacts at different angles on the TFT LCD screen 6 in actual use, and the impact angle can be adjusted during the vibration of the TFT LCD screen 6, which is convenient for the work of the staff.
