Description
Technical Field
[0001] The utility model relates to the technical field of backlight source production, in particular to a light bar feeding device used for backlight source production. Background Art
[0002] A backlight is a light source located behind a liquid crystal display (LCD). Its luminous effect directly affects the visual quality of the liquid crystal display module (LCM). LCDs do not emit light themselves; they display graphics or images by modulating the light from the backlight. The main types of backlights include light-emitting diode (LED) backlights and cold cathode fluorescent lamp (CCFL) backlights. Compared to traditional CCFL backlights, LED backlights offer low power consumption, low heat generation, high brightness, and a long lifespan. These advantages make them poised to completely replace traditional backlight systems in recent years.
[0003] Currently, backlight sources are mainly assembled manually by workers. During manual assembly, human errors often occur, making it impossible to ensure the accuracy of the relative position between the LED lamp and the light guide plate, and thus unable to ensure the uniformity of the distance between the LED lamp and the light guide plate.
[0004] For example, Chinese patent CN202702089U discloses a mold for assembling a backlight source. The device includes a mold body with a recessed portion in the middle; a row of blocks located at the bottom of the recessed portion, the row of blocks including a plurality of blocks spaced apart and arranged in a row, the row of blocks dividing the recessed portion into a first space and a second space located on either side of the row of blocks, the first space being the limit interval of the light guide plate in the backlight source group, the second space being the limit interval of the LED light bar in the backlight source group, and the intervals between any two of the multiple blocks being the limit intervals of the individual LED lights on the LED light bar. This mold for assembling a backlight source avoids errors caused by manual assembly and ensures uniformity of the distance between the LED lights and the light guide plate when assembling the backlight source of a small-sized product.
[0005] However, the device requires manual loading, which is labor-intensive, time-consuming, and prone to fatigue and errors due to repetitive operations. This results in unstable product quality, low production efficiency, and high labor costs.
[0006] To this end, we propose a light bar loading device for backlight production to solve the above problems. Utility Model Content

[0018] 2. The light bar loading device used in the backlight production is equipped with a material-retrieving mechanism. When the feeding plate sends out the light bar, the driving motor is started to make the No. 3 connecting rod drive the No. 2 connecting rod to move, so that the slide plate slides inside the No. 1 chute, and then the No. 1 connecting rod slides in the No. 2 chute and the No. 3 chute.
