Abstract
Description
Technical Field
[0001] This utility model relates to the field of backlight position correction technology, and in particular to a backlight position correction device. Background Technology
[0002] A backlight is an illumination component located behind a display device. It provides a uniform light source for LCD displays and other similar devices, making the screen content clearly visible. It is typically composed of components such as a light source (e.g., LED), a light guide plate, and a diffuser plate. Through light guiding and diffusion technologies, the light emitted by the light source is evenly distributed. Backlights are widely used in various display devices such as mobile phones, computers, and televisions, and their performance affects the brightness, contrast, and color performance of the displayed image.
[0003] A backlight position correction device is used to precisely adjust the position of the backlight in a display device to ensure that the backlight is installed correctly and to guarantee the display effect. It usually uses sensors to sense the current position information of the backlight, compares it with a preset standard position, calculates the deviation data, and finally, based on the deviation, uses mechanical adjustment mechanisms, such as lead screws and slide rails, to precisely move and correct the position of the backlight so that it reaches the ideal position.
[0004] In existing technologies, some backlight position correction devices rely mainly on manual operation or simple tooling fixtures to determine the backlight position during traditional backlight installation. Manual operation is limited by the worker's skill level and fatigue, resulting in highly unstable correction accuracy, which is difficult to meet the consistency requirements of large-scale production. In a small display equipment production workshop, the position deviation failure rate of manually corrected backlights in subsequent inspections was as high as 20%, which led to a significant reduction in product quality and reduced overall production efficiency. Additional manpower and resources were required for rework or scrapping of defective products. Therefore, a backlight position correction device is proposed to solve the above problems.

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the driven stage is driven to rotate by a motor. Then, the driven stage drives the driven column to move synchronously through the driven groove, which in turn drives the driven plate to move synchronously. Then, the connecting column pulls the connecting plate to slide and tighten inward. The correction plate contacts the backlight product on the conveyor belt to correct the product. The elastic buffer function of the spring prevents the correction plate from damaging the backlight product, thereby achieving accurate correction of the backlight position and ensuring that the product is installed and the display effect is accurate in subsequent processes. The spring buffer and the continuously running conveyor belt complement each other, which not only prevents the product from being damaged during the correction process, but also achieves efficient and continuous product transportation, greatly improving production efficiency and product quality.

The correction plate 14 is used to correct the backlight product and can also be buffered by the elasticity of the springs 12 to prevent damage to the backlight product.
[0034] The adjustment assembly includes a fixed post 16, which provides fixation and support for the second spring 17. The second spring 17 is fixedly connected to the inner top wall of the fixed post 16. The second spring 17 has an elastic function and provides elastic support for its connecting post 18.

[0035] Reference Figures 2 to 4 The connecting plate 13 is externally slidably connected to the inside of the connecting box 11. The connecting box 11 provides limiting and guiding functions for the connecting plate 13. The inner wall of the base plate 1 is provided with a conveyor belt 19, which is used to transport backlight products. The bottom of the correction plate 14 is in contact with the top of the conveyor belt 19, which can prevent the backlight products from getting stuck between the guide correction plate 14 and the conveyor belt 19, and can stably perform correction processing on the backlight products. The inner wall of the inkjet box 2 is fixedly connected with a curtain, which is used to block light inside the inkjet box 2. The bottom of the connecting plate 10 is fixedly connected with a cylinder 15, which is the power source of the adjustment component. The top of the connecting box 11 is fixedly connected to the drive end of the cylinder 15.

The top of the fixed column 16 is fixedly connected to the bottom of the connecting plate 10. The connecting plate 10 provides fixing and support for the fixed column 16.
[0037] Working principle: When the equipment is activated, when the backlight product is conveyed to the inkjet box 2 via the conveyor belt 19, and the backlight product needs to be calibrated first, the driven table 5 is driven by the motor 4 to start rotating. Then, the driven table 5 drives the driven column 7 to move synchronously via the driven groove 6. Then, the driven column 7 drives the driven plate 8 to move synchronously. Then, the driven plate 8 pulls the connecting plate 10 inward and tightens it through the connecting column 9. As the connecting plate 10 moves, the calibration plate 14 contacts the backlight product on the conveyor belt 19 to calibrate the product. During this process, the elastic buffer function of the spring 12 avoids damage to the backlight product by the calibration plate 14, ensuring that the calibration process is safe and accurate. At the same time, the conveyor belt 19 continues to run, conveying the backlight products to the calibration area in sequence. The inkjet box 2 also works synchronously to complete the inkjet printing on the product, ensuring the inkjet printing effect.
[0038] When processing backlight products of different specifications, the cylinder 15 drives the connecting box 11 to move up and down. The connecting column 18 slides inside the fixed column 16, which can adapt to the synchronization of the cylinder 15 and thus provide auxiliary support for the connecting box 11. This enables flexible adjustment of the height of the connecting box 11 and the calibration plate 14, so that the calibration plate 14 can be in the optimal position of the backlight product for calibration, thereby accurately adapting to the height of different backlight products and efficiently completing the calibration work.
