[0002] A computer display is an important output device in a computer system. It is responsible for converting the digital signals processed by the computer into visual image information and presenting it to the user. The common computer displays mainly include two types: liquid crystal displays and organic light-emitting diode displays. LCD controls the transmission and blocking of light through the arrangement change of liquid crystal molecules to achieve image display. It has advantages such as low power consumption and stable picture, and is widely used in daily office and home computers;

[0003] At present, after the production of computer displays, quality inspection is usually required.

Connecting blocks are provided on the left and right sides of the front side of the upper part of the handle. A first rotating rod is connected between the inner sides of the two connecting blocks. A rotating block is rotatably provided on the first rotating rod. The present invention is provided with a sliding rod and a first spring, which can limit the rotating block as needed, thus avoiding the situation of the rubber block popping out for a long time, and effectively extending the service life of the rubber block;

[0004] However, in the actual application process of the above device, there are obvious defects. When performing the test task, it is often necessary for the operator to hold the device for operation, which makes the entire detection process highly dependent on manual labor. This not only consumes a large amount of manpower, but also greatly increases the work intensity of the operator and reduces the work efficiency. In addition, when using this device, it is impossible to perform anti-friction and compressive performance tests on the display screen to be tested, which results in a relatively single detection function and low detection efficiency, and it is difficult to meet the comprehensive and efficient detection requirements. To sum up, in order to improve the detection efficiency and functionality, it is extremely urgent to improve the design of this device. Summary of the Invention

[0017] A test method for a computer display screen includes the following steps:

[0018] Step 1: Start the driving mechanism, turn on the first motor of the first driving component, drive the first synchronous pulley to rotate, and make the other first synchronous pulley rotate synchronously through the synchronous belt, drive the first lead screws in the two side rails to rotate, make the sliding block slide in the side rail, drive the two clamping mechanisms to displace, and adjust their spacing to adapt to the size of the display screen to be tested;

[0019] Step 2: Adjust the distance between the clamping mechanisms. After the driving mechanism is adjusted, start the second motor to drive the second synchronous pulley to rotate. With the help of the synchronous belt, the other second synchronous pulley rotates synchronously, driving the second lead screws in the two vertical rails to rotate, causing the sliding blocks to slide in the vertical rails, driving the mounting arms to move, and moving the driving rollers on the inner side of the mounting plate to appropriate positions;

[0020] Step 3: Clamp the display screen to be tested. Place the display screen to be tested between the inner sides of the driving rollers to complete the clamping of the display screen;

[0021] Step 4: Drive the displacement of the display screen. Start the third motor to drive the driving rollers to rotate. The driving rollers are in contact with the top and bottom of the display screen, causing the display screen to move horizontally into the device for detection;

[0022] Step 5: Conduct the detection of the display screen. When the display screen moves to the bottom of the detection component, start the first electric push rod to push the cross plate downward. The stamping block acts on the display screen, and the pressure sensor detects the pressure to determine the compressive performance; when the stamping block contacts the display screen, the telescopic spring makes the friction plate contact the top of the screen, and the third motor drives the displacement of the display screen to conduct the anti-friction performance detection;

[0023] Step 6: Process the detection results and waste materials. After the detection is completed, if the display screen is qualified, a qualified result is output; if it is unqualified, an unqualified result is output; if the display screen is damaged, the waste product enters the collection box through the guiding hopper. Pull the bridge-type handrail, and the collection box is slid off through the guide rail slider to process the waste materials.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] First, in the present invention, the driving mechanism of the present invention plays a key role during the operation of the device. When the first motor of the first driving component is started, the first synchronous pulley rotates accordingly. With the transmission of the synchronous belt, the other first synchronous pulley also rotates synchronously. This two-way rotation further drives the first lead screws in the two side rails to rotate synchronously. Since the thread directions at both ends of the first lead screw are opposite, its rotation can drive the sliding block to slide in the side rail, driving the two clamping mechanisms to generate reciprocating displacements. Through such an operation mode, the distance between the two clamping mechanisms can be accurately adjusted. Regardless of the size of the display screen to be tested, stable clamping can be achieved, laying a foundation for the subsequent detection process, ensuring the stability and accuracy of the detection process, and meeting the detection requirements of display screens of different specifications;

[0026] Second, in the present invention, the clamping mechanism is an important part for realizing automatic detection. After the inner spacing is adjusted, the second motor is started to drive the second synchronous pulley to rotate. The synchronous belt makes the other second synchronous pulley rotate stably, driving the second lead screws in the two vertical rails to operate. The thread directions of the two ends of the second lead screw are opposite, synchronously driving the sliding block to slide in the vertical rail, driving the mounting arm to move longitudinally, making the driving rollers on the inner side of the mounting plate approach or move away from each other, placing the display screen to be tested between the driving rollers to complete clamping. Then the third motor is started, and the driving rollers rotate along the top and bottom of the display screen to drive its lateral displacement. The display screen is placed from one side, and the device automatically completes the movement in and out before and after detection, greatly reducing the dependence on manual detection, improving the detection efficiency, and optimizing the detection process;

[0027] Third, in the present invention, the testing mechanism has a comprehensive detection function and a convenient waste collection mechanism. When the display screen to be tested moves to the bottom of the detection component, the first electric push rod is started to make the cross plate move downwards. The punching block acts on the display screen, and the pressure sensor detects the pressure in real time. Whether it is qualified or not is judged according to the pressure threshold and the state of the display screen. If the display screen is damaged during the detection, the waste product enters the collection box through the guiding hopper. When the punching block contacts the display screen, the telescopic spring makes the friction plate stably contact the top of the screen. The third motor is started to drive the displacement of the display screen, and the friction plate generates friction on it to assist in detecting the anti-friction performance. The support pillar penetrates through the chassis to support the stable telescopic movement of the friction plate. After the detection is completed, the bridge-type handrail is pulled, and the collection box can be easily removed by sliding through the guide rail slider, facilitating the collection of waste materials and ensuring the efficient and orderly progress of the detection work.

[0041] The testing mechanism 5 includes an external frame 51, the external frame 51 is fixedly connected to the middle part of the outer side of the frame 1, a first electric push rod 52 is fixedly connected to the top of the external frame 51, the output end of the first electric push rod 52 penetrates through the external frame 51 and is fixedly connected with a fourth motor 53, the output end of the fourth motor 53 is fixedly connected with a cross plate 54, one side of the bottom of the cross plate 54 is fixedly connected to a second electric push rod 55, the output end of the second electric push rod 55 is fixedly connected with a detection component 56. During use, the driving mechanism 2 drives the first lead screw 23 to rotate through the first driving component 22 at one end of the side rail 21. Since the thread directions at both ends of the first lead screw 23 are opposite, its rotation will cause the sliding blocks 24 threadedly connected at both ends to slide within the side rail 21. The sliding blocks 24 drive the clamping mechanism 3 connected to the top to displace, realizing the adjustment of the distance between the clamping mechanisms 3 to adapt to different sizes of the display screens 4 to be tested and clamping them. During testing, the display screen 4 to be tested is placed inside the clamping mechanism 3. The first electric push rod 52 at the top of the external frame 51 pushes the fourth motor 53 and the connected cross plate 54 downward. The second electric push rod 55 on one side of the bottom of the cross plate 54 pushes the detection component 56 close to the display screen 4 to be tested to perform various performance tests on it. And the waste collection mechanism 6 at the bottom of the frame 1 can collect the waste generated during the testing process. And because the fourth motor 53 is provided, the detection component 56 can be driven to rotate by starting the fourth motor 53, which is convenient for adjusting the detection position of the detection component 56.

[0042] Please refer to Figures 1 - 3 The first driving component 22 includes a side frame 221, the side frame 221 is fixedly connected to one end of the back surface of the frame 1, a first motor 222 is fixedly connected to the rear side of the side frame 221, the output end of the first motor 222 penetrates through the side frame 221, the rear ends of the side rails 21 are rotatably connected with first synchronous pulleys 223, the front surface of the first synchronous pulley 223 is fixedly connected with the rear end of the first lead screw 23, and the first synchronous pulleys 223 are connected by a synchronous belt. During use, when it is necessary to drive the lead screw to rotate, start the first motor 222 fixedly connected to the rear side of the side frame 221. The rotational power of the output end of the first motor 222 is transmitted through the side frame 221. Since the rear ends of the side rails 21 are rotatably connected with the first synchronous pulleys 223, and the front surface of the first synchronous pulley 223 is fixedly connected with the rear end of the first lead screw 23, and at the same time the first synchronous pulleys 223 are connected by a synchronous belt, the rotation of the output end of the first motor 222 drives the associated first synchronous pulley 223 to rotate. This rotating first synchronous pulley 223 drives another first synchronous pulley 223 to rotate synchronously through the synchronous belt. Furthermore, the two first synchronous pulleys 223 synchronously drive the first lead screw 23 fixed to them to rotate, realizing the function of driving the lead screw to rotate to drive the subsequent components to act.

[0043] Please refer to Figures 1 - 3 and Figures 5 - 7, the clamping mechanism 3 includes a fixed arm 31, the fixed arm 31 is fixedly connected to the top of the sliding block 24, the inner end of the fixed arm 31 is fixedly connected with a connecting rod 32, both outer ends of the connecting rod 32 are fixedly connected with adjusting components 33, a second driving component 34 is arranged on the top of the adjusting component 33, and power components 35 are fixedly connected to both ends on both sides of the adjusting component 33. The adjusting component 33 includes a vertical rail 331, the vertical rail 331 is fixedly connected to both sides of the top of the connecting rod 32, a second lead screw 332 is rotatably connected inside the vertical rail 331, the thread directions at both ends of the second lead screw 332 are opposite, both ends of the second lead screw 332 are threadedly connected with sliding blocks 333, the sliding blocks 333 are slidably connected to both ends inside the vertical rail 331, the inner sides of the sliding blocks 333 are connected to the power components 35, the second driving component 34 is fixedly connected to the top of the vertical rail 331, the second driving component 34 includes a top frame 341, the top frame 341 is fixedly connected to the top of the vertical rail 331, a second motor 342 is fixedly connected to the top of the top frame 341, the output end of the second motor 342 penetrates through the top frame 341 and is fixedly connected with a second synchronous pulley 343, a second synchronous pulley 343 is also rotatably connected to the top of another top frame 341, the second synchronous pulleys 343 are connected by a synchronous belt in a transmission manner, the bottom of the second synchronous pulley 343 is connected to the top of the second lead screw 332, the power component 35 includes a mounting arm 351, the mounting arm 351 is fixedly connected to the inner side of the sliding block 333, a mounting plate 352 is fixedly connected to the inner end of the mounting arm 351, concave frames 353 are fixedly connected to the inner side of the mounting plate 352 at equal intervals, third motors 354 are fixedly connected to the inner ends of the concave frames 353 located in the middle, driving rollers 355 are rotatably connected inside the concave frames 353, the output end of the third motor 354 is fixedly connected to one end of the driving roller 355, the display screen 4 to be measured is arranged between the inner sides of the driving rollers 355, the overall cross-sectional shapes of the inner channels of the side rail 21 and the vertical rail 331 are both set as convex shapes, the cross-sectional shapes of the sliding blocks 333 and the sliding block 24 are also set as convex shapes, wear-resistant gaskets are fixedly connected to the outer surfaces of the sliding blocks 333 and the sliding block 24. When the clamping mechanism 3 works, the first driving component 22 drives the sliding block 24 to slide in the side rail 21, and the fixed arm 31 fixed to the top of the sliding block 24 moves accordingly. When it is necessary to adjust the clamping action on the display screen, the second motor 342 on the top of the top frame 341 is started, the output end of the second motor 342 drives the second synchronous pulley 343 to rotate. Because the two second synchronous pulleys 343 are connected by a synchronous belt in a transmission manner, they will synchronously drive the other second synchronous pulley 343 to rotate, and then drive the second lead screw 332 connected thereto to rotate. Since the thread directions at both ends of the second lead screw 332 are opposite, its rotation drives the sliding blocks 333 threadedly connected at both ends to slide in the vertical rail 331 in the opposite direction. The sliding blocks 333 drive the mounting arms 351 connected to the inner sides to move longitudinally, and the mounting arms 351 drive the concave frames 353 and the driving rollers 355 on the mounting plates 352 at the inner ends to move. After the display screen 4 to be measured is placed between the inner sides of the driving rollers 355,Start the third motor 354 located at the inner end of the middle concave frame 353. The output end of the third motor 354 drives the driving roller 355 to rotate, thereby realizing the clamping of the display screen 4 to be measured and driving its lateral displacement. The convex-shaped cross-section design of the side rail 21, the vertical rail 331, the sliding block 333, and the sliding block 24, combined with wear-resistant gaskets, ensures the stability and durability of each component during sliding.,

[0044] Please refer to Figures 1 - 3 and Figures 8 - 9, the detection component 56 includes a movable block 561 which is slidably connected to the bottom of the cross plate 54. A pressure sensor 562 is fixedly connected to the bottom of the movable block 561. A fixed column 563 is fixedly connected to the bottom of the pressure sensor 562. A stamping block 564 is fixedly connected to the bottom of the fixed column 563. A bent rod 565 is fixedly connected to one side of the fixed column 563. A chassis 566 is fixedly connected to the outer end of the bent rod 565. A telescopic spring 567 is fixedly connected to the bottom of the chassis 566. A friction plate 568 is fixedly connected to the bottom of the telescopic spring 567. Pillars 569 are fixedly connected to the top of the friction plate 568 at equal intervals in a circular arrangement. The top of the pillar 569 penetrates the chassis 566, and the pillar 569 is slidably connected to the chassis 566. The waste collection mechanism 6 includes a support frame 61 and a guiding hopper 62. The support frame 61 is fixedly connected to both sides of the bottom of the frame 1. Installation holes 64 are formed on both sides of the outer end of the support frame 61. The bolts are used in cooperation with the installation holes 64 to fixedly install this device, which is convenient for use. The guiding hopper 62 is fixedly connected to the bottom of the frame 1. Guide rails 65 are fixedly connected to the inner sides of the support frames 61. Sliders 66 are slidably connected to the inside of the guide rails 65. A collection box 67 is fixedly installed on the inner side of the slider 66. The collection box 67 is arranged directly below the guiding hopper 62. A bridge-type handrail 68 is fixedly connected to the middle of one end of the collection box 67. Universal balls 63 are rotatably connected to both sides of the bottom of the collection box 67 at equal intervals in a linear arrangement. When the detection component 56 works, when the cross plate 54 moves downward under the action of an external drive, the movable block 561 slides on the bottom of the cross plate 54, driving the pressure sensor 562, the fixed column 563 and the stamping block 564 below to descend together. The stamping block 564 contacts the display screen 4 to be tested, and the pressure sensor 562 monitors the pressure value in real time to judge the compressive performance of the display screen. During the stamping process, the chassis 566 connected to the outer end of the bent rod 565 on one side of the fixed column 563 also descends accordingly. The telescopic spring 567 at the bottom of the chassis 566 is compressed, so that the friction plate 568 stably contacts the top of the display screen 4 to be tested. If the display screen 4 to be tested is laterally displaced under the drive of other components at this time, since the friction plate 568 is relatively stationary, the anti-friction performance of the display screen 4 to be tested can be detected. During this period, the pillar 569 slides in the chassis 566, playing a role in stably supporting the friction plate 568. The working principle of the waste collection mechanism 6 is that when the display screen is damaged during the detection process, the waste slides down through the guiding hopper 62. The collection box 67 slides on the guide rails 65 on the inner sides of the support frames 61 through the inner sliders 66 and can be flexibly pulled out. The collection box 67 is located directly below the guiding hopper 62 to catch the falling waste. After the collection is completed, by pulling the bridge-type handrail 68 in the middle of one end of the collection box 67 and using the universal balls 63 rotatably connected to both sides of the bottom to assist in moving, it is convenient to move the collection box 67. During use, by operating the fourth motor 53, the pushing direction of the second electric push rod 55 can be changed, so that this device can conveniently adjust the positions of the friction plate 568 and the stamping block 564 at the bottom.By the telescopic cooperation of the second electric push rod 55 and the drive of the fourth motor 53 to drive the cross plate 54 to rotate, it can flexibly detect different positions at the top of the display screen 4 to be measured, further improving the detection convenience and adaptation ability during the detection of the device and enhancing the detection effect.

[0045] A test method for a computer display screen includes the following steps:

[0046] Step 1: Start the drive mechanism 2, turn on the first motor 222 of the first drive component 22, drive the first synchronous pulley 223 to rotate, and through the synchronous belt, make another first synchronous pulley 223 rotate synchronously, driving the first lead screw 23 in the two side rails 21 to rotate, so that the sliding block 24 slides in the side rail 21, driving the two clamping mechanisms 3 to displace, and adjusting their spacing to adapt to the size of the display screen 4 to be measured;

[0047] Step 2: Adjust the spacing of the clamping mechanism 3. After the adjustment of the drive mechanism 2 is completed, start the second motor 342 to drive the second synchronous pulley 343 to rotate, and through the synchronous belt, make another second synchronous pulley 343 rotate synchronously, driving the second lead screw 332 in the two vertical rails 331 to rotate, so that the sliding block 333 slides in the vertical rail 331, driving the mounting arm 351 to move, and making the driving rollers 355 on the inner side of the mounting plate 352 move to appropriate positions;

[0048] Step 3: Clamp the display screen 4 to be measured, place the display screen 4 to be measured between the inner sides of the driving rollers 355 to complete the clamping of the display screen;

[0049] Step 4: Drive the display screen to displace. Start the third motor 354 to drive the driving rollers 355 to rotate. The driving rollers 355 are attached to the top and bottom of the display screen, and the display screen is horizontally displaced into the device for detection;

[0050] Step 5: Perform display screen detection. When the display screen moves to the bottom of the detection component 56, start the first electric push rod 52 to push the cross plate 54 downward. The stamping block 564 acts on the display screen, and the pressure sensor 562 detects the pressure to determine the compressive performance; when the stamping block 564 contacts the display screen, the telescopic spring 567 makes the friction plate 568 contact the top of the screen, and the third motor 354 drives the display screen to displace to perform the anti-friction performance detection;

[0051] Step 6: Process the detection results and waste materials. After the detection is completed, if the display screen is qualified, a qualified result is output; if it is unqualified, an unqualified result is output; if the display screen is damaged, the waste product enters the collection box 67 through the guiding hopper 62; pull the bridge-type handrail 68, and slide the collection box 67 through the slider 66 of the guide rail 65 to process the waste materials.

[0052] The working principle of the present invention is as follows: The present invention is provided with a driving mechanism 2. When the device is in use, the first motor 222 of the first driving component 22 is started to drive the first synchronous pulley 223 to rotate. Since the first synchronous pulleys 223 are connected by a synchronous belt in a transmission manner, the rotation of one first synchronous pulley 223 can drive the other first synchronous pulley 223 to rotate synchronously through the synchronous belt. The two first synchronous pulleys 223 rotate synchronously, thereby driving the first lead screws 23 inside the two side rails 21 to rotate synchronously. Since the thread directions at both ends of the first lead screw 23 are opposite, when the first lead screw 23 rotates, it can drive the sliding block 24 to slide inside the side rail 21. The sliding of the sliding block 24 can synchronously drive the two clamping mechanisms 3 to reciprocate. By adjusting the distance between the two clamping mechanisms 3, display screens 4 to be measured with different sizes can be stably clamped;

[0053] The present invention is provided with a clamping mechanism 3. When the device is in use, after the inner distance of the clamping mechanism 3 is adjusted, the second motor 342 is started to drive the second synchronous pulley 343 to rotate. Since the second synchronous pulleys 343 are connected by a synchronous belt in a transmission manner, the rotation of one second synchronous pulley 343 can stably drive the other second synchronous pulley 343 to rotate synchronously, thereby driving the second lead screws 332 inside the two vertical rails 331 to rotate. Since the thread directions at both ends of the second lead screw 332 are opposite, it can synchronously drive the sliding block 333 to slide synchronously at both ends inside the vertical rail 331. Adjusting the sliding of the sliding block 333 can drive the two mounting arms 351 to slide longitudinally in a reciprocating manner. The mounting arms 351 drive the driving rollers 355 inside the mounting plate 352 to move relative to each other. The display screen 4 to be measured is placed between the inner sides of the driving rollers 355. The driving rollers 355 can clamp the display screen 4 to be measured. The third motor 354 is started to drive the driving rollers 355 to rotate. The driving rollers 355 rotate in contact with the top and bottom of the display screen 4 to be measured, and can drive the display screen 4 to be measured to displace horizontally. During detection, the display screen 4 to be measured is placed from one side of the driving roller 355. The device can automatically drive it to displace horizontally into the device for detection and automatically move it out after the detection is completed. This process realizes automatic detection, reduces the dependence on manual detection, and improves the detection efficiency;

[0054] The present invention is provided with a testing mechanism 5. When the device conducts detection, the display screen 4 to be tested is moved to the bottom of the detection component 56, and the first electric push rod 52 is activated to push the cross plate 54 downward. The stamping block 564 on the detection component 56 at the bottom of the cross plate 54 acts on the display screen 4 to be tested. During the detection process, the pressure sensor 562 is used to detect the pressure received by the display screen 4 to be tested, so as to achieve the detection function. When the pressure reaches the set threshold and the display screen 4 to be tested is not damaged, it is determined that the display screen is qualified; if the pressure does not reach the set threshold and the display screen 4 to be tested is damaged, it is determined to be unqualified. If the display screen 4 to be tested is damaged during the detection process, the broken waste products enter the collection box 67 through the guiding hopper 62 for collection. When the stamping block 564 contacts the display screen 4 to be tested, the telescopic spring 567 expands and contracts, enabling the friction plate 568 to stably contact the top of the display screen 4 to be tested. The third motor 354 is activated to drive the driving wheel to drive the display screen 4 to be tested to move horizontally. Since the friction plate 568 is stationary and the display screen 4 to be tested moves, a frictional effect can be generated on the top of the display screen 4 to be tested to assist in detecting its anti-friction performance. During the detection period, the support column 569 penetrates through the chassis 566 to guide and support the friction plate 568, enabling it to stably expand and contract. After the detection is completed, the bridge-type handrail 68 is pulled, and the collection box 67 slides through the slider 66 inside the guide rail 65, and the collection box 67 can be removed. This testing mechanism 5 is convenient for automatic detection, and at the same time, it is convenient to quickly disassemble and assemble the collection box 67, which is conducive to collecting the detection waste materials.
