Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screens, and in particular to an electrical measuring frame for a liquid crystal display screen. Background Art

[0002] Liquid crystal display screens are a type of flat panel display. In the production process of liquid crystal display screens, there is a process called "electrical testing process", which is to apply a driving voltage signal to the liquid crystal display through an electric testing machine to detect whether the actual display state of the display screen meets the quality requirements, and select defective products for scrapping. The existing detection method is to place the display screen on an electric testing frame, which requires staff to adjust the angle by themselves to visually inspect the display screen. In addition, most of the existing electric testing frames are fixed and difficult to adjust, making the detection work inconvenient.

[0003] According to the authorization announcement number: CN113643634B, an electric measuring frame that is easy to adjust the angle includes: a base, a placement plate, a detection plate, an angle adjustment mechanism and an adjustable positioning mechanism; the placement plate and the base are rotatably connected, and a receiving groove for placing a liquid crystal display panel to be tested is provided on the placement plate; the adjustable positioning mechanism is arranged in the receiving groove, and the adjustable positioning mechanism is used to position the liquid crystal display panel to be tested; the detection plate and the placement plate are rotatably connected, and the detection plate has a covering position covering the placement plate and a hovering position away from the placement plate; the electric measuring frame that is easy to adjust the angle described in the application is driven to connect the angle by rotating the detection plate to the covering position, and then the detection plate is brought into contact with the liquid crystal display panel to be tested placed on the placement plate.

[0004] Based on the cooperation of the above-mentioned angle adjustment mechanism and adjustable positioning mechanism, the effect of adjustable angle is achieved. However, since it is necessary to first use the adjustable positioning mechanism to fix it during use, and then adjust the angle through the angle adjustment mechanism, the steps are relatively cumbersome in the process of realizing the function. Therefore, there is still room for simplification of the operation.

[0005] Therefore, in summary, there is an urgent need for a simple and efficient liquid crystal display screen electrical test frame. Summary of the invention

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Embodiment: A liquid crystal display screen electrical test frame, such as Figure 1 and Figure 2 As shown, it includes a base 1, an electric push rod 2, a universal joint 3, a placement plate 4 and an electric suction cup 5. The top of the base 1 is in an inclined state, with a tendency of being lower in the front and higher in the back. The inclined state conforms to ergonomics and is convenient for the human body's viewing angle. The two sides of the bottom of the base 1 are in an extended state, so that the contact area of ​​the bottom is increased, thereby stabilizing the overall position. An electric push rod 2 is longitudinally fixedly installed on the top of the base 1. The electric push rod 2 is the main driving source and can complete the height adjustment of the device. A universal joint 3 is arranged on the telescopic end of the electric push rod 2, and a placement plate 4 is arranged on the upper end of the universal joint 3. The universal joint 3 can complete the overall 360-degree rotation angle adjustment of the placement plate 4. Electric suction cups 5 are installed on the left and right sides of the rear of the placement plate 4. The electric suction cup 5 runs through the placement plate 4 and is used to adsorb and fix the display screen.

[0024] like Figure 2-Figure 5 As shown, it also includes a damping rod 6, which is rotatably provided on the left and right sides of the top of the base 1, and an empty groove is opened on the top of the damping rod 6. The damping rod 6 is used to connect the rotation action and limit the rotation speed; a telescopic rod 7, which is penetrated by the damping rod 6, and the upper end of the telescopic rod 7 is hingedly connected to the placement plate 4, connected between the damping 6 and the placement plate 4, and used to cooperate with the overall rotation work; a support block 8 and a slider 9, a slide groove 10 is opened on the lower left and right sides of the front part of the placement plate 4, and a support block 8 is slidably provided on the slide groove 10 through the slider 9, and the support block 8 and the slider 9 are snap-connected, the support block 8 is in an inverted L hook shape and a rubber block is arranged on its inner side to fix the position of the display screen; a rubber pad 11, rubber pads 11 are arranged on the left and right sides of the bottom of the base 1, and the rubber pad 11 is used to increase the friction between the base 1 and the contact surface, thereby stabilizing its position.

[0025] When it is necessary to conduct electrical testing on the LCD screen, the staff first places the entire device on a horizontal plane. At the same time, the rubber pad 11 increases the friction between the contact surfaces, so that the device remains in a more stable state. Then the staff can place the LCD screen to be tested on the placement plate 4, and its lower side is against the support block 8, and the other side of the screen is against the groove of the placement plate 4, so that the two ends are fixed. At the same time, the fixed position of the screen can be adjusted by sliding the support block 8. After the overall position is fixed, the electric suction cup 5 is started to adsorb the back side of the screen, so that its upper, lower and rear three positions are all fixed. The staff can perform multi-directional positioning of the screen by twisting the placement plate 4. Observation and detection, in the process of twisting the placement plate 4, the universal joint 3 also rotates accordingly, and the damping rod 6 and the telescopic rod 7 also tilt and rotate accordingly, and the connection position between the telescopic rod 7 and the damping rod 6 changes, so that the placement plate 4 is sufficient to achieve a smooth 360-degree rotation, and the damping rod 6 limits the rotation control, so that its rotation process is smoother. If height adjustment is required, the electric push rod 2 can be started to adjust up and down. In the same way, it can still be rotated for detection. In summary, repeat the operation to complete the overall detection work, then disengage the support block 8 from the slider 9, and then close the electric suction cup 5 to take out the display for the next display screen detection.
