Description

Technical Field

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

[0002] A TFT liquid crystal display screen is an active matrix liquid crystal display that uses thin film transistors (TFTs) to drive each liquid crystal pixel. TFT liquid crystal display screens have the characteristics of high speed, high brightness, and high contrast, and can provide high-quality image display effects. Moreover, TFT liquid crystal display screens are widely used in multiple fields, mainly including the following aspects: consumer electronics products, medical devices, industrial automation, automotive electronics, and other fields. At the same time, when producing TFT liquid crystal display screens, it is usually necessary to detect the appearance, display performance, electrical performance, menu function, reliability, etc. of the TFT liquid crystal display screens.

[0003] Reliability testing mainly includes the impact of vibration on TFT liquid crystal display screens. Currently, during testing, the TFT liquid crystal display screen is usually directly placed on a vibration device or clamped on both sides of the TFT liquid crystal display screen through a clamping plate for vibration testing. The detection method is single and cannot be simulated according to the actual usage situation, resulting in a reduction in the reliability testing effect. For example, when a TFT liquid crystal display screen is used, it is sometimes embedded in the inner side of a device on all four sides. When the material hardness of the TFT liquid crystal display screen and the embedded object differs greatly, vibration may cause problems. For example, if the object material is hard, such as a metal material, and the TFT liquid crystal display screen is relatively brittle, during vibration, the hard material object may be more likely to maintain its shape, while the TFT liquid crystal display screen is more likely to be affected by the impact force. The hard material object may also generate a large squeezing force on the edge of the TFT liquid crystal display screen due to factors such as inertia during vibration, and in severe cases, it will form an impact. At the same time, in some industrial production sites or transportation tools, strong vibration may increase the interaction force between the object and the TFT liquid crystal display screen, resulting in the object impacting the edge of the TFT liquid crystal display screen.

[0004] Moreover, due to the wide range of usage environments of TFT liquid crystal display screens, the TFT liquid crystal display screen is also easily impacted by external objects during vibration. When the display screen is embedded in an object and vibrates: in addition to its own inertial force, it will also be subject to squeezing forces, frictional forces, etc. from the object. Interaction forces will be generated at the contact parts between the object and the display screen, and the magnitudes and directions of these forces will continuously change with the vibration. Therefore, vibration will also affect the impact, thereby affecting the reliability testing of the TFT liquid crystal display screen. Existing vibration devices cannot impact the panel and side edges of the TFT liquid crystal display screen in different directions during the vibration of the TFT liquid crystal display screen, which will also lead to a reduction in the reliability testing effect. Therefore, a detection device for a TFT liquid crystal display screen is proposed to address the above problems. Summary of the Invention

The present invention will be further described below in conjunction with specific embodiments. Embodiment

[0036] As Figures 1 - 10As shown in the figure, a detection device for a TFT liquid crystal screen includes a vibration instrument main body 4 and a control cabinet 5. A control cabinet 5 is arranged on one side of the vibration instrument main body 4, and a placement plate 401 is arranged at the top of the vibration instrument main body 4. The vibration instrument main body 4 can vibrate in the X-axis direction, Y-axis direction, and Z-axis direction, and the vibration instrument main body 4 is a prior art and will not be elaborated here in detail. A support shell 3 is fixedly connected to the top of the placement plate 401. An embedding mechanism 1 is arranged at one end of the support shell 3, and a TFT liquid crystal screen 6 is embedded inside the embedding mechanism 1. An impact mechanism 2 is arranged at one end of the support shell 3. The embedding mechanism 1 includes a first clamping plate 109, a second clamping plate 112, and a third clamping plate 119 arranged around the TFT liquid crystal screen 6. The second clamping plate 112 and the third clamping plate 119 have the same size, and the lengths of the second clamping plate 112 and the third clamping plate 119 are longer than the length of the first clamping plate 109, so that the third clamping plate 119 can be adapted to TFT liquid crystal screens 6 of different lengths. When it is necessary to make the TFT liquid crystal screen 6 in an embedded state, only a first clamping plate 109 with a suitable length needs to be selected, which is convenient for the staff to quickly make the TFT liquid crystal screen 6 in an embedded state. One end of the third clamping plate 119 is fixedly connected to a second electric telescopic rod 114, and the second electric telescopic rod 114 can clamp the third clamping plate 119 and the TFT liquid crystal screen 6 together. A second fixing plate 113 is fixedly connected to the outside of the second electric telescopic rod 114, and the second fixing plate 113 is fixedly connected to the support shell 3. A flipping assembly is arranged at one end of the second clamping plate 112, and a conversion assembly is arranged at one end of the first clamping plate 109. The four sides of the TFT liquid crystal screen 6 can be completely wrapped by the first clamping plate 109, the second clamping plate 112, and the third clamping plate 119, so as to simulate the scenario when the TFT liquid crystal screen 6 is embedded in the device. And through the vibration of the vibration instrument main body 4, the degree of influence of the TFT liquid crystal screen 6 when it is embedded in the device can be simulated, so as to compare with the degree of influence of the TFT liquid crystal screen 6 when it is not embedded in the device, and then more comprehensive and accurate detection data can be provided, improving the effect of the reliability detection of the TFT liquid crystal screen 6 and providing more valuable data for the subsequent optimization and improvement of the reliability of the TFT liquid crystal screen 6.

[0037] As a further improvement of the present invention, as Figure 2 , Figure 3 and Figure 4As shown in the figure, the conversion component includes a first fixing plate 101 fixedly connected to the support shell 3. One end of the first fixing plate 101 is fixedly connected to a fixing beam 102. One end of the fixing beam 102 is fixedly connected to a first motor 104. The end of the main shaft of the first motor 104 is fixedly connected to a fixing cylinder 106. The inner side of the fixing cylinder 106 is fixedly connected to a first bearing 105, and the first bearing 105 is fixedly connected to the fixing beam 102. One end of the fixing cylinder 106 is fixedly connected to a rotating cylinder 110. One end of the rotating cylinder 110 is closed and the other end is open, ensuring that the fixing cylinder 106 can be normally fixed to the rotating cylinder 110. One end of the fixing beam 102 is fixedly connected to a first electric telescopic rod 103. The rotating cylinder 110 is provided with a hole for the first electric telescopic rod 103 to extend out at one end, so that the first electric telescopic rod 103 can smoothly push the first clamping plate 109 on one side of the TFT liquid crystal screen 6. A guiding component is arranged inside the rotating cylinder 110, and one end of the guiding component is fixedly connected to the first clamping plate 109. The first clamping plate 109 with a suitable width is selected according to the width of the TFT liquid crystal screen 6 with different specifications. The first motor 104 drives the fixing cylinder 106 to rotate, then the fixing cylinder 106 drives the rotating cylinder 110 to rotate, and then the rotating cylinder 110 drives the first clamping plate 109 to rotate through the first guiding shaft 107 until the first clamping plate 109 with a suitable length is on one side of the TFT liquid crystal screen 6. At the same time, the first clamping plate 109 with a suitable length is also on one side of the first electric telescopic rod 103. The first electric telescopic rod 103 can push the corresponding first clamping plate 109 to clamp the TFT liquid crystal screen 6 together.

[0038] As a further improvement of the present invention, as Figure 3 and Figure 5 shown in the figure, the guiding component includes a first guiding shaft 107 slidably connected to the rotating cylinder 110, and the first guiding shaft 107 is fixedly connected to the first clamping plate 109. The other end of the first guiding shaft 107 is fixedly connected to a limiting block 108. A first spring 111 is arranged on the outer side of the first guiding shaft 107, and both ends of the first spring 111 are fixedly connected to the rotating cylinder 110 and the limiting block 108 respectively. When the first electric telescopic rod 103 pushes the first clamping plate 109, the first clamping plate 109 will drive the first guiding shaft 107 to move along the rotating cylinder 110, and at the same time, the first spring 111 will also be compressed by the limiting block 108. Under the guiding action of the first guiding shaft 107, it can ensure that the first clamping plate 109 can normally clamp the TFT liquid crystal screen 6, and when the first electric telescopic rod 103 resets, under the action of the first spring 111, the first guiding shaft 107 can drive the first clamping plate 109 to separate and reset from the TFT liquid crystal screen 6.

[0039] As a further improvement of the present invention, as Figure 3As shown, at least four first clamping plates 109 are provided around the rotary drum 110, and the lengths of each of the first clamping plates 109 are different. At the same time, the width of the first clamping plate 109 is designed according to the width of the TFT liquid crystal display screen 6 of different specifications, and the number of the guiding components is the same as the number of the first clamping plates 109. By providing the first clamping plates 109 with different lengths, the embedding use of the TFT liquid crystal display screens 6 of different specifications can be satisfied.

[0040] As a further improvement of the present invention, as Figure 2 、 Figure 6 and Figure 7 shown, the flipping component includes a third fixing plate 115 fixedly connected to the support shell 3. One end of the third fixing plate 115 is rotatably connected to a third electric telescopic rod 116. The other end of the third electric telescopic rod 116 is rotatably connected to a flap 117, and the flap 117 is rotatably connected to the support shell 3. A fourth electric telescopic rod 118 is fixedly connected to the inner side of the flap 117, and the fourth electric telescopic rod 118 is fixedly connected to the second clamping plate 112. When it is necessary to perform impact detection on the edge during the vibration of the TFT liquid crystal display screen 6, the third electric telescopic rod 116 drives the flap 117 to rotate clockwise, so that the flap 117 drives the second clamping plate 112 to rotate together through the fourth electric telescopic rod 118, so that the second clamping plate 112 rotates to one side of the support 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 display screen 6, and the second clamping plate 112 can be normally clamped with the TFT liquid crystal display screen 6 through the fourth electric telescopic rod 118.

[0041] As a further improvement of the present invention, as Figure 1 、 Figure 2 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10As shown in the figure, the impact mechanism 2 includes a horizontal rotation assembly disposed below the support housing 3. One end of the horizontal rotation assembly is fixedly connected to a support block 205. One end of the support block 205 is fixedly connected to a longitudinal rotation assembly. One end of the longitudinal rotation assembly is fixedly connected to a support frame 213. A moving plate 215 is slidably connected to the inner side of the support frame 213. One end of the moving plate 215 is fixedly connected to a fifth electric telescopic rod 217, and the fifth electric telescopic rod 217 is slidably connected to the support frame 213. The other end of the fifth electric telescopic rod 217 is fixedly connected to an impact block 219. A second spring 218 is disposed outside the fifth electric telescopic rod 217, and both ends of the second spring 218 are fixedly connected to the support frame 213 and the moving plate 215 respectively. A release assembly is disposed at one end of the moving plate 215. The impact block 219 can perform impact detection on the TFT liquid crystal screen 6 at different angles, so as to simulate the external force conditions that the TFT liquid crystal screen 6 may receive during actual use. Moreover, the detection data obtained by simultaneously performing vibration and impact can be compared with the detection when the TFT liquid crystal screen 6 is only impacted, thereby providing more comprehensive and accurate detection data, improving the effect of the reliability detection of the TFT liquid crystal screen 6, and providing more valuable data for the subsequent optimization and improvement of the reliability of the TFT liquid crystal screen 6. When impact detection needs to be performed, the fifth electric telescopic rod 217 is first brought into contact with the edge of the TFT liquid crystal screen 6 with the impact block 219, and then the elastic force of the second spring 218 causes the fifth electric telescopic rod 217 to impact the edge of the TFT liquid crystal screen 6 with the impact block 219, so as to realize the impact detection of the edge of the TFT liquid crystal screen 6 when the TFT liquid crystal screen 6 vibrates.

[0042] As a further improvement of the present invention, as Figure 9 and Figure 10As shown in the figure, the release component includes a sixth electric telescopic rod 223 fixedly connected to the support frame 213. The top end of the sixth electric telescopic rod 223 is fixedly connected to a fixed frame 221. One end of the fixed frame 221 is fixedly connected to a fourth motor 222. The end of the main shaft of the fourth motor 222 is fixedly connected to a second gear 220, and the second gear 220 is rotatably connected to the fixed frame 221. The top of the second gear 220 meshes with a strip-shaped rack 216, and the strip-shaped rack 216 is fixedly connected to the moving plate 215. The inner side of the moving plate 215 is slidably connected to a second guide shaft 214, and the second guide shaft 214 is fixedly connected to the support frame 213. When it is necessary to stretch the second spring 218, the fourth motor 222 drives the second gear 220 to rotate clockwise. Then, the second gear 220 stretches the second spring 218 through the strip-shaped rack 216 and the moving plate 215, so that the second spring 218 is at an appropriate stretched length. At this time, the impact block 219 is separated from the edge of the TFT liquid crystal screen 6. Then, the sixth electric telescopic rod 223 drives the second gear 220 to quickly separate from the strip-shaped rack 216 through the fixed frame 221, so that the second gear 220 releases the restriction on the strip-shaped rack 216. Then, the second spring 218 will drive the moving plate 215 to move together. And when the second spring 218 is in the natural state, at this time, the teeth of the second gear 220 move upward and can mesh with the teeth of the strip-shaped rack 216, so as to ensure the normal meshing and separation of the second gear 220 and the strip-shaped rack 216, without manual movement of the strip-shaped rack 216, ensuring that the impact test can be successfully completed when the TFT liquid crystal screen 6 vibrates.

[0043] As a further improvement of the present invention, as Figure 1 、 Figure 2 and Figure 8 shown, the horizontal rotation component includes a second bearing 202 fixedly connected to the support shell 3. The inner side of the second bearing 202 is fixedly connected to a connecting ring 203. The bottom end of the connecting ring 203 is fixedly connected to a base 204. One end of the support shell 3 is fixedly connected to a second motor 201. The end of the main shaft of the second motor 201 is fixedly connected to the base 204, and the base 204 is fixedly connected to the support block 205. When it is necessary to change the impact angle of the impact block 219 in the horizontal direction, the second motor 201 drives the base 204 to rotate. Then, the base 204 will drive the impact block 219 to rotate around the vertical center line of the second motor 201 through the support block 205, the arc-shaped guide rail 206, the slider 209, the support frame 213, and the fifth electric telescopic rod 217 until the impact block 219 is at an appropriate impact angle in the horizontal direction, simulating the external force impacts on the TFT liquid crystal screen 6 at different angles in actual use.

[0044] As a further improvement of the present invention, as Figure 1 and Figure 9As shown in the figure, the longitudinal rotation assembly includes an arc-shaped guide rail 206 fixedly connected to the support block 205. A slider 209 is slidably connected to the outer side of the arc-shaped guide rail 206. One end of the slider 209 is fixedly connected to a connecting cover 210. A third motor 211 is fixedly connected to the inner side of the connecting cover 210. The end of the main shaft of the third motor 211 is fixedly connected to a first gear 212. One end of the first gear 212 meshes with an arc-shaped rack 207, and the arc-shaped rack 207 is fixedly connected to the arc-shaped guide rail 206. Baffles 208 are fixedly connected to one end of the arc-shaped rack 207 and the arc-shaped guide rail 206. When it is necessary to change the impact angle of the impact block 219 in the longitudinal direction, the third motor 211 drives the first gear 212 to roll along the arc-shaped rack 207. At the same time, the slider 209 also slides along the arc-shaped rack 207, so that the slider 209 drives the impact block 219 to rotate around the center of the arc-shaped rack 207 through the support frame 213 and the fifth electric telescopic rod 217 until the impact block 219 is at an appropriate impact angle in the longitudinal direction, simulating the external force impacts on the TFT liquid crystal screen 6 at different angles in actual use, and the adjustment of the impact angle can be realized during the vibration of the TFT liquid crystal screen 6, which is convenient for the work of the staff.

[0045] As a further improvement of the present invention, as Figure 1 , Figure 2 , Figure 6 and Figure 8 shown, holes for the bar-shaped rack 216 to move are provided on the inner sides of the slider 209 and the arc-shaped guide rail 206, ensuring that the bar-shaped rack 216 has sufficient displacement space, so as to adjust the different impact forces of the impact block 219.

[0046] The first motor 104, the second motor 201, the third motor 211, and the fourth motor 222 are all servo motors and have a self-locking function. 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 with hydraulic rods or cylinders according to actual use conditions.

[0047] Workflow: When the TFT liquid crystal screen 6 needs to be in the embedded state, select the first clamping plate 109 with an appropriate width according to the width of the TFT liquid crystal screen 6 of different specifications, make the first motor 104 drive the fixed cylinder 106 to rotate, then the fixed cylinder 106 drives the rotating cylinder 110 to rotate, and then the rotating cylinder 110 drives the first clamping plate 109 to rotate through the first guide shaft 107 until the first clamping plate 109 with an appropriate length is on one side of the TFT liquid crystal screen 6. At the same time, the first clamping plate 109 with an appropriate length will also be on one side of the first electric telescopic rod 103. The first electric telescopic rod 103 can push the corresponding first clamping plate 109 to clamp with the TFT liquid crystal screen 6. At the same time, the second electric telescopic rod 114 drives the third clamping plate 119 to clamp with the TFT liquid crystal screen 6, and the fourth electric telescopic rod 118 drives the second clamping plate 112 to clamp with the TFT liquid crystal screen 6. The first clamping plate 109, the second clamping plate 112 and the third clamping plate 119 can wrap all around the TFT liquid crystal screen 6, so as to simulate the scenario when the TFT liquid crystal screen 6 is embedded in the device. Then the vibration instrument main body 4 can vibrate the TFT liquid crystal screen 6 through the placement plate 401 and the support shell 3. The vibration of the vibration instrument main body 4 can simulate the degree of vibration influence when the TFT liquid crystal screen 6 is embedded in the device, so as to compare with the degree of vibration influence when the TFT liquid crystal screen 6 is not embedded in the device, and then provide more comprehensive and accurate detection data, improve the effect of the reliability detection of the TFT liquid crystal screen 6, and provide more valuable data for the subsequent optimization and improvement of the reliability of the TFT liquid crystal screen 6;

[0048] When it is necessary to detect the impact on the edge during the vibration of the TFT liquid crystal screen 6, the third electric telescopic rod 116 drives the flap 117 to rotate clockwise, and the flap 117 drives the second clamping plate 112 to rotate together through the fourth electric telescopic rod 118, so that the second clamping plate 112 rotates to one side of the support shell 3, ensuring that the second clamping plate 112 will not affect the normal impact of the impact block 219 on the edge of the TFT liquid crystal screen 6, and the fourth electric telescopic rod 118 can drive the second clamping plate 112 to be normally clamped with the TFT liquid crystal screen 6. Then, the fourth motor 222 drives the second gear 220 to rotate clockwise. Then, the second gear 220 stretches the second spring 218 through the strip-shaped rack 216 and the moving plate 215, so that the second spring 218 is in a suitable stretching length. At this time, the impact block 219 is separated from the edge of the TFT liquid crystal screen 6. Then, the sixth electric telescopic rod 223 drives the second gear 220 to quickly separate from the strip-shaped rack 216 through the fixed frame 221, so that the second gear 220 releases the restriction on the strip-shaped rack 216. Then, the second spring 218 will drive the moving plate 215 to move together; and when the second spring 218 is in the natural state, at this time, the teeth of the second gear 220 move upward to mesh with the teeth of the strip-shaped rack 216, so as to ensure the normal meshing and separation of the second gear 220 and the strip-shaped rack 216, without manually moving the strip-shaped rack 216, ensuring that the impact test can be successfully completed when the TFT liquid crystal screen 6 vibrates;

[0049] When it is necessary to change the impact angle of the impact block 219 in the horizontal direction, the second motor 201 drives the base 204 to rotate. Then, the base 204 drives the impact block 219 to rotate around the vertical center line of the second motor 201 through the support block 205, the arc-shaped 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, simulating the external force impacts on the TFT liquid crystal screen 6 at different angles in actual use;

[0050] When it is necessary to change the impact angle of the impact block 219 in the longitudinal direction, the third motor 211 drives the first gear 212 to roll along the arc-shaped rack 207. At the same time, the slider 209 also slides along the arc-shaped rack 207. The slider 209 drives the impact block 219 to rotate around the center of the arc-shaped rack 207 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, simulating the external force impacts on the TFT liquid crystal screen 6 at different angles in actual use, and the impact angle can be adjusted during the vibration of the TFT liquid crystal screen 6, which is convenient for the work of the staff.
