Description

Technical Field

[0001] This invention relates to the field of screen testing technology, and in particular to a screen fault testing device for mobile marketing terminals. Background Technology

[0002] A touchscreen linearity tester is a specialized testing device used to test the linearity of touchscreens. In the touchscreen industry, it is sometimes simply referred to as a line tester. A fully functional touchscreen linearity tester can test many types of touchscreens, such as four-line screens, five-line screens, capacitive screens, etc. In recent years, due to the widespread use of touchscreen mobile phones and touchscreen terminals, this type of touchscreen testing equipment has been widely applied. It typically uses a computer to control an automatic worktable. The touchscreen under test is placed on the worktable, which has a pen tip that can simulate a human finger or stylus. The computer controls this pen tip to draw lines on the touchscreen, and simultaneously, data is sampled through lines connected to the touchscreen terminal. Finally, the computer analyzes and calculates the sampled data to derive various parameters of the touchscreen's linearity. This allows for testing of the display screen when a mobile phone or terminal screen malfunctions, revealing the cause of the malfunction or providing valuable reference for future screen improvements. However, existing touch screen linearity testers have certain drawbacks. First, the screen needs to be fixed according to different screen sizes during testing, which requires different placement slots to fix the equipment, making it cumbersome and affecting the efficiency of screen testing. Insecure clamping can cause the testing pen to loosen during use, resulting in uneven force on the testing pen. Furthermore, when testing the touch pen, it is easy to have a large impact with the testing pen, which can damage the equipment or the screen, affecting the accuracy of the test data or the use of the screen.

The second guide rod 1206 passes through the interior of the second pressing plate 1203 and is connected to the first pressing plate 1202. The two ends of the second pressing plate 1203 are slidably connected to the second guide rod 1206. By clamping the detection line inserted into the display screen in the fixing structure 12, the second pressing plate 1203 is clamped to the first pressing plate 1202 under the action of the third telescopic spring 1207. At this time, the detection line can be prevented from falling out of the display screen terminal, ensuring the reliability of the connection between the detection line and the display screen terminal.

[0034] In addition, a servo motor is provided at one end of the second moving rail 7, and the second moving rail 7 moves along the first moving rail 6. A servo motor is provided on the detection head 8, and the detection head 8 moves along the second moving rail 7. The detection head 8 moves in the vertical direction. A display terminal is placed in the placement cavity 9, and the display terminal is in contact with the ejection structure 11 and the clamping device 10. The fixing structure 12 is clamped to the detection wire connected to the display terminal.

[0035] It should be noted that this invention is a screen fault testing device for a mobile marketing terminal. In use, the touchscreen scratch tester 1 is connected to the power supply via a power cord. At this time, the touchscreen scratch tester 1 and the information display screen 2 can display relevant information. When testing the display screen, the screen is placed in the placement cavity 9 of the touchscreen scratch tester 1. The screen is then clamped by the clamping device 10. Specifically, the screen is placed in the placement cavity 9, and then the screen is pressed, causing the side of the screen to push the clamping block 1003. This causes the fixing rod 1006 of the clamping block 1003 to move along the inside of the first fixing box 1001. Simultaneously, the first pushing plate 1008 and the moving cavity 1005 of the first fixing box 1001... In the sliding connection, the display screen can be pressed into the stepped groove 1004 of the clamping block 1003, so that the first push plate 1008, under the action of the first telescopic spring 1009, causes the clamping block 1003 to clamp the display screen. At this time, the display screen is fixed between the clamping devices 10. Then, when pressing the display screen, the ejection structure 11 at the bottom of the display screen pushes the ejection structure 11 upward. Specifically, the second telescopic spring 1110 pushes the second push plate 1108 in the second fixing box 1103, so that the second push plate 1108 and the floating plate 1102 float upward together, so that the rubber pad 1101 on the upper surface of the floating plate 1102 contacts the display screen, thereby making the display screen terminal and the display screen... The stepped groove 1004 of the clamping block 1003 abuts against each other, thereby clamping the display screen between the clamping device 10 and the ejection structure 11. The display screen terminal is connected to the touch screen scribing tester 1 via the detection line, so that the terminal display screen in the placement cavity 9 can be fixed more securely. Moreover, the clamping device 10 and the ejection structure 11 can ensure that display screen terminals of different sizes or thicknesses can be clamped, which has a wide range of applications and higher detection efficiency. It does not require frequent equipment changes according to different display terminal sizes. Since a servo motor is provided at one end of the second moving rail 7 and the second moving rail 7 moves along the first moving rail 6, and a servo motor is provided on the detection head 8 and the detection head 8 moves upward along the second moving rail 7. The detection head 8 moves vertically, causing the servo motor to drive the second moving rail 7 to move along the first moving rail 6. The detection head 8 moves along the second moving rail 7, bringing the detection stylus on the detection head 8 into contact with the display screen. This allows the detection stylus in the detection head 8 to detect the sensitivity of the display screen, thus enabling the detection of display screen faults. The detection line connected to the display screen is fixed by the fixing structure 12. Specifically, during insertion, the second clamping plate 1203 is lifted upwards, separating the first clamping plate 1202 and the second clamping plate 1203, allowing the detection line to pass between the first clamping groove 1204 and the second clamping groove 1205. When the second clamping plate 1203 is released...Under the action of the third telescopic spring 1207, the first clamping plate 1202 and the second clamping plate 1203 are clamped together, fixing the detection line located between the first clamping groove 1204 and the second clamping groove 1205. The third telescopic spring 1207 also clamps the second clamping plate 1203 to the first clamping plate 1202. This prevents the detection line from falling out of the display terminal, ensuring the reliability of the connection between the detection line and the display terminal.
