[0008] Further, the light source body comprises two side plates and a bottom plate, the two side plates are spliced with the bottom plate and fixed by screws.The splicing and screw fixing mode makes the assembly process relatively intuitive and simple.The staff can clearly distinguish the positional relationship of each component during assembly, only need to align the two side plates with the bottom plate according to the preset splicing mode, and then fasten by using screws, which reduces the assembly difficulty and improves the assembly efficiency.

[0031] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0032] Please see Figures 1 to 8 The present invention provides a combined light source for continuous delivery curing, comprising: a light source body 1, a heat dissipation component 2, and several independently operating light source circuit boards 3;

[0033] like Figure 1 and Figure 2 The light source body 1 shown in this embodiment includes two side plates 11 and a bottom plate 12. The side plates 11 and the bottom plate 12 are spliced ​​together and fixed with screws. When the side plates 11 and the bottom plate 12 are assembled, they form the following structure: Figure 3 The frame structure shown has a mounting cavity 13.

[0034] The heat dissipation assembly 2 is fixed to the light source body 1. Specifically, in this embodiment, the heat dissipation assembly 2 includes a heat dissipation plate 21 and several cooling fans 22. The structure of the heat dissipation plate 21 is as follows: first mounting holes 211 are provided on both sides of the heat dissipation plate 21, and second mounting holes 111 matching the positions of the first mounting holes 211 are provided on the side plates 11. During assembly, the heat dissipation plate 21 is placed into the mounting cavity 13, the first mounting holes 211 and the second mounting holes 111 are aligned, and then they are locked together with screws. To further increase the heat dissipation effect of the heat dissipation plate 21, the heat dissipation plate of this embodiment... 21 is made of metal materials with good thermal conductivity, such as aluminum, copper, aluminum alloy, or copper alloy. Furthermore, multiple sets of evenly distributed heat dissipation fins 212 are provided on the heat dissipation plate 21. Preferably, second ventilation openings 112 are also provided on the two side plates 11. The second ventilation openings 112 are adjacent to the side wings of the heat dissipation fins 212, so hot air will rise naturally. The proximity of the second ventilation openings 112 to the side wings of the heat dissipation fins 212 allows hot air to be discharged more smoothly from the second ventilation openings 112. At the same time, cold air from the outside can enter from other positions, forming good air convection and accelerating heat dissipation.

[0035] Meanwhile, in this embodiment, the cooling fan 22 can be directly mounted on the heat sink 212 using self-tapping screws. The fan's rotation drives airflow, drawing away heat from the heat sink 212. Specifically, a first vent 121, matching the position of the cooling fan 22, is provided on the base plate 12. When the cooling fan 22 is running, the first vent 121 serves as an inlet for cool air. Cool air enters through the vent, flows directly to the heat sink 212, exchanges heat with it, absorbs heat, and becomes hot air, which is then exhausted by the cooling fan 22. This organized airflow improves heat dissipation efficiency and avoids poor heat dissipation caused by air stagnation.

[0036] Several light source circuit boards 3 are arranged horizontally and fixed on one side of the heat dissipation component 2, and the light source circuit boards 3 are tightly spliced ​​together; multiple LED beads 31 are arranged at equal intervals on each light source circuit board 3. Specifically, this embodiment has a total of twelve sets of light source circuit boards 3, which are arranged horizontally on the other side of the heat dissipation plate 21 away from the heat dissipation fins 212. Each of the twelve sets of light source circuit boards 3 adopts an independent control mode and can be lit individually, thus forming twelve equally divided light source zones. The light source circuit boards 3 are arranged horizontally, and the number of light source circuit boards 3 lit can be selected according to the actual product width or the width of the conveyor belt, thereby meeting the needs of the product and the width of the conveyor belt, making it flexible and convenient to use.

[0037] In this embodiment, a splicing structure 4 is provided on the light source body 1 to enable splicing of two light source bodies 1. Specifically, the splicing structure 4 includes a splicing component 41 and splicing grooves 42 provided on both sides of the base plate 12. The upper wall of the splicing groove 42 is a connecting arm 421 extending outward from the light source body 1, and the lower wall of the splicing groove 42 is an abutment portion 422. The length of the connecting arm 421 is less than that of the abutment portion 422. The cross-section of the splicing component 41 is convex, such as... Figure 6 and Figure 7 As shown, when two light source bodies 1 are spliced ​​together, the splicing grooves 42 on the two light source bodies 1 are joined to form a groove that matches the splicing component 41. The splicing component 41 is directly inserted into this groove, and the splicing component 41 is fixedly connected to the walls of the two splicing grooves 42 respectively. Thus, through the cooperation of the splicing component 41 and the splicing grooves 42, two different combined light sources can be spliced ​​into a continuous whole to adapt to the needs of product and conveyor belt length. To ensure that the light effect at the splicing point is not uneven, the distance from the outermost LED bead 31 on the light source circuit board 3 to the edge of the light source circuit board 3 is half the distance between two LED beads 31. Figure 4 and Figure 5 As shown, each light source circuit board 3 has three rows of LED beads 31. The spacing between any two adjacent LED beads 31 remains consistent, both horizontally and vertically. For example, the spacing between two adjacent LED beads 31 can be set to 10.6mm, while the distance from the outermost LED bead 31 to the light source circuit board 3 is 5.3mm. Figure 6 As shown, when the two light source bodies 1 are spliced ​​together, the distance between the outermost LED beads 31 of the two light source bodies 1 is 5.3 + 5.3 = 10.6 mm. This can avoid the uneven light effect caused by the different spacing of the LED beads 31.

[0038] like Figures 1 to 3As shown, in this embodiment, the two ends of the two side plates 11 extend upward to form protective portions 113, which are slightly higher than the light source circuit board 3. The higher two ends can first contact the colliding object when the light source body 1 is subjected to external impact, playing a buffering and blocking role, reducing the direct impact of the collision on the light source circuit board 3, and reducing the risk of damage to the circuit board due to collision, such as bumps and knocks that may occur during transportation or installation, and can effectively protect the integrity of the internal circuit; in addition, it can also constrain the light emitted by the light source to a certain extent, reduce the scattering of light to the side, make the light more concentrated in the direction of the target, and improve the utilization efficiency of light and the directionality of illumination.

[0039] A handrail 14 is provided on one side of the light source body 1. When the light source body 1 needs to be moved, the handrail 14 provides a part that is easy for the user to grip and apply force, so that the user can push or pull the light source more easily and place it in the required position. The handrail 14 can make the movement process more stable and safe, and reduce the risk of the equipment tipping over or being damaged due to improper force.

[0040] The working principle of this utility model is as follows: by setting twelve horizontally arranged light source circuit boards 3, the entire combined light source forms twelve independently illuminating zones. Appropriate numbers of light source circuit boards 3 can be selected to illuminate for products or conveyor belts of different widths to meet the required brightness. In this embodiment, taking a spacing of 10.6mm between two adjacent LED beads 31 as an example, assuming the product width is approximately 60mm, we can select to illuminate the LED beads 31 in two zones, thus completely covering the product without energy waste. Furthermore, the main body 1 of the light source 1 can be freely spliced. In particular, the spacing of the LED beads 31 ensures that uneven light effects do not occur after splicing. By splicing different numbers of combined light sources, the light source circuit boards 3 can be extended, achieving a seamless integration effect. This allows for the illumination of specific areas based on the product and conveyor belt length.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
