[0022] For small size liquid crystal display, in the production process, considering the requirements of production process, generally need to use CG paste technology, cover glass and liquid crystal display seamless paste together. In the process of CG paste, UV curing technology is particularly important, can quickly cure adhesive and paint, improve the production efficiency and reduce energy consumption, now generally use light source assembly to provide stable light source support. But in the process of use, the existing light source assembly is generally fixed on the pull wire above by aluminum profile, there is a problem of height adjustment difficulty.

[0023] Therefore, the utility model embodiment provides a light source assembly, can realize the height adjustment in the process of use of light source, through the adjustment mechanism that sets, make light source move towards the direction that is close to or far from the opening, thereby make light source and display screen surface maintain proper height, to ensure the best curing efficiency and product quality.

[0024] In order to better understand the above technical scheme, the above technical scheme is explained in detail below in conjunction with the drawings.

[0025] As shown in Figure 1 , Figure 2 , Figure 3 The utility model provides a light source assembly, comprising:

[0026] Casing 10, inside having cavity and being equipped with opening in one side;

[0027] Light source 20, activity is equipped in cavity, and the light direction of light source 20 is towards opening;And

[0028] Adjusting mechanism 30, is equipped with casing 10, and adjusting mechanism 30 is driven with light source 20 connection to make light source 20 move towards or away from opening.

[0029] In the technical scheme adopted in the embodiment, the shell 10 is arranged to provide space for installation and adjustment of the light source 20, and an opening is arranged on one side of the shell 10 to facilitate light output. The light source 20 is arranged to provide high-intensity ultraviolet light to rapidly cure the adhesive or paint in a short time. Moreover, the light source 20 is movably arranged, so that the position of the light source 20 can be adjusted as needed to adapt to different application scenarios. The adjustment mechanism 30 is arranged to accurately adjust the irradiation distance of the light source 20 according to specific requirements, so that the light source 20 moves towards or away from the opening, thereby optimizing the lighting effect. It can be understood that the height of the light source 20 directly affects the light intensity reaching the surface of the target product. When the light source 20 moves towards the opening, the closer the distance between the light source 20 and the target product, the greater the light intensity; when the light source 20 moves away from the opening, the farther the distance between the light source 20 and the target product, the smaller the light intensity. The technical scheme of the embodiment of the utility model is arranged to adjust the height of the light source 20 according to the curing requirements of the adhesive of the target product by the adjustment mechanism 30, so as to maintain appropriate light intensity and ensure optimal curing effect and product quality.

[0030] Specifically, the light source assembly includes a shell 10, a light source 20, and an adjustment mechanism 30.

[0031] The shell 10 is generally made of metal materials such as stainless steel and aluminum alloy, which has sufficient strength and rigidity to withstand the weight of the internal light source 20 and other components, and can provide support.

[0032] The light source 20 is movably arranged in the shell 10 to provide stable lighting support to rapidly cure the adhesive or paint in a short time. The structure of the light source 20 is not specifically limited, as long as it can provide temperature to cure the adhesive or paint. The time for the target product to be irradiated and cured under the light source 20 is not specifically limited, and can be set according to the absorption and reaction speed of different curing materials.

[0033] The adjusting mechanism 30 is used to realize the height adjustment of the light source 20. It can be understood that the light source 20 can be moved towards or away from the opening by the adjusting mechanism 30, so as to adjust the distance between the light source 20 and the target product, so as to change the light intensity on the surface of the target product. The adjusting mechanism 30 can be a bolt or a threaded rod which is screwed with the shell 10. When it is needed to increase the light intensity, the bolt or the threaded rod is rotated to move the light source 20 towards the opening, so as to reduce the distance between the light source 20 and the target product. When it is needed to reduce the light intensity, the bolt or the threaded rod is rotated in the opposite direction to move the light source 20 away from the opening, so as to increase the distance between the light source 20 and the target product. Of course, in order to improve the curing effect and the product quality, a UV energy meter or other measuring tools can also be arranged to monitor the change of the light intensity in real time, so as to ensure that the light intensity reaches the required level, and the influence of the excessive proximity or excessive distance of the light source 20 on the curing effect and the product quality is reduced.
