Description

Technical Field

[0001] This utility model relates to the field of display screen testing technology, specifically a display screen tester. Background Technology

[0002] With the development of semiconductor technology, my country's semiconductor industry has become increasingly mature, among which semiconductor display technology is particularly prominent. Semiconductor display refers to the general term for display technology that independently controls each smallest display unit through semiconductor devices, and is usually displayed through corresponding display screens.

[0003] Before a semiconductor display screen is put into use, it needs to be tested using a display screen tester. Usually, the tester needs to hold the test equipment by hand and test the relevant parameters on the semiconductor display screen, or a semi-automatic equipment can be used for testing.

[0004] However, most of the current industry uses semi-automatic or manual testing methods, which results in poor stability of semiconductor displays. This is because without a fixed device, the display will be unstable when held by hand during the testing process, and it will slide when placed on a flat surface. At the same time, the testing equipment cannot be accurately positioned on the corresponding display. Utility Model Content

[0005] To address the shortcomings of existing technologies, most industries currently employ semi-automatic or manual testing methods, resulting in poor stability of semiconductor displays. This is because the lack of a fixed device makes the display unstable when held by hand during testing, causing it to slide when placed on a flat surface. Additionally, the testing equipment cannot accurately position itself on the display. This invention proposes a display tester.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The display screen tester of this utility model includes a device body, an installation plate is fixedly connected inside the device body, rails are fixedly connected to both sides of the front part of the installation plate, a grating is provided at the front part of the rails, the grating is fixedly connected to the bottom of the inner side of the device body, a lifting mechanism is provided inside the rails, the lifting mechanism includes a screw, the screw is rotatably connected to both ends inside the rails, a moving block is threadedly connected to the outer side of the screw, the front part of the moving block is fixedly connected to the lifting seat, a pressure plate is fixedly connected to the bottom end of the lifting seat, and a transmission mechanism is provided at the top of the rails.

[0007] Preferably, the top of the device body is provided with multiple sets of positioning blocks, the top of the positioning blocks is provided with a display screen, and the bottom of the pressure plate is in contact with the display screen.

[0008] Preferably, the moving block is inside the track, and the cross-section of the moving block is the same as the cross-section inside the track.

[0009] Preferably, the transmission mechanism includes two sets of rotating columns, and the bottom ends of the two sets of rotating columns pass through the track and are fixedly connected to the top end of the screw. A transmission belt is sleeved on the outside of the rotating columns.

[0010] Preferably, a protective shell is provided on the outer side of the transmission belt, and the protective shell is fixedly connected to the top of the two sets of tracks.

[0011] Preferably, a motor is fixedly connected to one end of the top of the protective shell, and the output shaft of the motor passes through the protective shell and is fixedly connected to one of the sets of rotating columns.

[0012] The advantages of this utility model are:

[0013] 1. This utility model, through the structural design of the lifting mechanism, realizes the function of placing the display screen on the positioning block, activating the motor and the transmission mechanism to drive the two sets of screws to rotate, thereby causing the lifting block and pressure plate to descend and make the pressure plate tightly adhere to the top of the display screen, and fixing the display screen through the pressure plate. Various components set at the bottom of the pressure plate complete the function of display screen detection. This solves the problem that most of the current industry uses semi-automatic or manual detection methods, which result in poor stability of semiconductor display screens. Because there is no fixed equipment, the display screen will be unstable when held during the detection process, and it will slide when placed on a flat surface. At the same time, the detection equipment cannot accurately position the display screen.

[0014] 2. This utility model, through the structural design of the transmission mechanism, achieves a fixed connection between two sets of rotating columns and two sets of screws. Furthermore, the outer sides of the two sets of rotating columns are sleeved by the same transmission belt. Therefore, as long as one set of rotating columns rotates, the other set will also rotate. That is, when the motor connected to one set of rotating columns is turned on, it will drive both sets of rotating columns and the two sets of screws to rotate together. This solves the problem that if the lifting seat needs to be raised and lowered stably and parallel to the bottom of the device body and the display screen, both sets of screws need to rotate simultaneously. Simultaneous rotation of both sets of screws requires both sets of moving blocks to rise and fall simultaneously and at the same distance. Previously, installing two sets of motors to control the rotation of the two sets of screws separately would increase production costs. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1 - Figure 4 As shown, the display screen tester includes a device body 1, an installation plate 2 fixedly connected inside the device body 1, rails 3 fixedly connected to both sides of the front of the installation plate 2, a grating 4 set at the front of the rails 3, the grating 4 fixedly connected to the bottom of the inner side of the device body 1, a lifting mechanism set inside the rails 3, the lifting mechanism including a screw 5, the screw 5 rotatably connected to both ends inside the rails 3, a moving block 6 threadedly connected to the outside of the screw 5, the front of the moving block 6 fixedly connected to the lifting seat 7, a pressure plate 8 fixedly connected to the bottom of the lifting seat 7, and a transmission mechanism set at the top of the rails 3.

[0023] During operation, the lifting mechanism's structural design enables the display screen 10 to be placed on the positioning block 9, and the motor 14, in conjunction with the transmission mechanism, drives the two sets of screws 5 to rotate. This causes the lifting block and pressure plate 8 to descend and press the pressure plate 8 against the top of the display screen 10, thus fixing the display screen 10 in place. Various components at the bottom of the pressure plate 8 complete the detection function of the display screen 10. This solves the problem that most of the current industry uses semi-automatic or manual detection methods, which result in poor stability of the semiconductor display screen 10. Because there is no fixed equipment, the display screen 10 is unstable when held during the detection process and will slide when placed on a flat surface. At the same time, the detection equipment cannot accurately position the display screen 10.

[0024] Furthermore, such as Figure 2As shown, the top of the device body 1 is provided with multiple sets of positioning blocks 9, the top of the positioning blocks 9 is provided with a display screen 10, and the bottom of the pressure plate 8 is in contact with the display screen 10.

[0025] During operation, the display screen 10 is correctly placed on the positioning block 9 according to the position of the positioning block 9 and the corresponding bottom indication. At this time, the detection device at the bottom of the pressure plate 8 can be directly aligned with the corresponding screen monitoring point. Meanwhile, as the pressure plate 8 descends and tightly fixes the display screen 10, the positioning block 9 also plays the role of fixing the display screen 10 with the pressure plate 8.

[0026] Furthermore, such as Figure 3 As shown, the moving block 6 is inside the track 3, and the cross-section of the moving block 6 is the same as the cross-section inside the track 3.

[0027] During operation, the rotation of screw 5 will cause the moving block 6 to have the same rotation tendency. Since the cross-section of moving block 6 is the same as the cross-section inside track 3, the rotation tendency of moving block 6 will be hindered by the inside of track 3. Also, due to the threaded connection between moving block 6 and screw 5, moving block 6 can move on screw 5 as screw 5 rotates.

[0028] Furthermore, such as Figure 4 As shown, the transmission mechanism includes a rotating column 11, and two sets of rotating columns 11 are provided. The bottom ends of the two sets of rotating columns 11 pass through the track 3 and are fixedly connected to the top end of the screw 5. A transmission belt 12 is sleeved on the outside of the rotating column 11.

[0029] During operation, the structural design of the transmission mechanism enables two sets of rotating columns 11 to be fixedly connected to two sets of screws 5. The outer sides of the two sets of rotating columns 11 are sleeved by the same set of transmission belts 12. Therefore, as long as one set of rotating columns 11 rotates, the other set of rotating columns 11 will also rotate. That is, when the motor 14 connected to one set of rotating columns 11 is turned on, it will drive the two sets of rotating columns 11 and the two sets of screws 5 to rotate together. This solves the problem that if the lifting seat 7 needs to be raised and lowered stably and parallel to the bottom of the device body 1 and the display screen 10, both sets of screws 5 need to rotate at the same time. Both sets of screws 5 need to rotate at the same time so that the two sets of moving blocks 6 can be raised and lowered at the same distance. Originally, it was necessary to install two sets of motors 14 to control the rotation of the two sets of screws 5 separately, which would increase the production cost.

[0030] Furthermore, such as Figure 4 As shown, a protective shell 13 is provided on the outside of the transmission belt 12, and the protective shell 13 is fixedly connected to the top of the two sets of tracks 3.

[0031] During operation, the transmission belt 12 is the key to the motor 14 controlling the rotation of the two sets of rotating columns 11. Therefore, a protective shell 13 is needed to protect the transmission belt 12 from falling off the rotating columns 11, and also to prevent external personnel from touching the transmission mechanism during operation and causing skin injury.

[0032] Furthermore, such as Figure 4 As shown, a motor 14 is fixedly connected to one end of the top of the protective shell 13, and the output shaft of the motor 14 passes through the protective shell 13 and is fixedly connected to one of the sets of rotating columns 11.

[0033] During operation, motor 14 serves as the power source, and the motor 14 is turned on to lift and lower the pressure plate 8.

[0034] Working principle: When the display screen 10 needs to be tested, the display screen 10 is correctly placed on top of multiple sets of positioning blocks 9. Then, the motor 14 is turned on to drive the rotating column 11 connected to it to rotate, thereby driving the transmission belt 12 and another set of rotating columns 11 to rotate. At this time, the two sets of screws 5 will also rotate. As the screws 5 rotate, the moving block 6 on the outside of the screws 5 begins to descend, driving the lifting seat 7 and the pressure plate 8 to descend. When the pressure plate 8 descends to be close to the top of the display screen 10, the cooperation between the pressure plate 8 and the positioning block 9 can fix the display screen 10. At the same time, the components at the bottom of the pressure plate 8 can test the display screen 10.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
