Description

Technical Field

[0001] The utility model relates to the technical field of LED products, in particular to an LED module curing frame structure. Background Art

[0002] Existing LED outdoor products need to be filled with glue on the lamp surface of the PCB board to achieve the effect of sealing and waterproofing. After filling the glue, it needs to be dried on a curing rack, which has the following problems:

[0003] Because the external dimensions of products of different specifications are different, the line operation needs to be changed when changing the product model, which is costly. Figure 1 and Figure 2 As shown, when the smaller module 3 is poured with glue and cured, the shell-removable pressure strip 2 is installed on the existing larger curing frame 1, and the pressure strip 2 and the curing frame 1 are only inserted into the positioning holes b on the curing frame through the two positioning columns a on the back of the pressure strip 2. During batch operation, the matching of the positioning columns a and the positioning holes b will be worn and loose, and the operation will jitter, causing the pressure strip to tilt and be uneven, resulting in uneven placement of the module, resulting in uneven molding of the silicone after curing, and inconsistent ink color after locking the panel, affecting the display effect. For this reason, we provide a LED module curing frame structure to solve the above problems. Utility Model Content

[0032] like Figures 3 to 5 Embodiment 1 shown:

[0033] A LED module curing frame structure includes a curing frame 1 and a fixing block 4, wherein the fixing blocks 4 are arranged at the edges of both sides of the upper surface of the curing frame 1, a pressure strip 2 is detachably mounted on the curing frame 1, the pressure strip 2 is located between two fixing blocks 4, a module 3 is supported and laid between the pressure strip 2 and the fixing blocks 4, a first sliding clamping structure 5 for fixing the pressure strip 2 to keep it horizontal is arranged between the curing frame 1 and the pressure strip 2, and the pressure strip 2 is slidably and detachably connected to the curing frame 1 through the first sliding clamping structure 5.

[0034] The first sliding clamping structure 5 includes a first protrusion 51 arranged on the upper surface of the curing frame 1, a first clamping groove 52 is opened inside the first protrusion 51, a first clamping block 53 matching the shape of the first clamping groove 52 is arranged at the bottom of the pressure strip 2, and the first clamping block 53 and the first clamping groove 52 are slidably connected.

[0035] See also Figure 3 and Figure 5 As shown, the first card block 53 is slid into the first card slot 52 to achieve installation of the pressure strip 2. At this time, the bottom surface of the first card block 53 is in contact with the bottom surface of the first card slot 52, thereby ensuring that the pressure strip 2 will not tilt, thereby preventing the silicone on the module 3 between the pressure strip 2 and the fixing block 4 from tilting or becoming uneven during curing, thereby improving the flatness of the silicone molding and meeting production requirements.

[0036] In this embodiment, the positions of the holding strip 2 and the first sliding engaging structure 5 can be adjusted according to the different sizes and shapes of the modules 3 .

[0037] A second sliding card structure 6 for detachable assembly is arranged between the two side edges of the upper surface of the curing frame 1 and the fixed block 4. The second sliding card structure 6 includes second protrusions 61 arranged on both sides of the upper surface of the curing frame 1. A second card groove 62 is opened inside the second protrusion 61. A second card block 63 adapted to the second card groove 62 is arranged on the bottom surface of the fixed block 4. The second card block 63 is slidably connected with the second card groove 62.

[0038] See also Figure 4 and Figure 5 As shown, before use, the second clamping block 63 at the bottom of the fixing block 4 is inserted into the second clamping groove 62 to achieve quick installation of the fixing block 4. When it is necessary to perform glue curing on modules 3 of different models or types, the fixing blocks 4 of different types or models can be replaced by sliding between the second clamping block 63 and the second clamping groove 62. When the fixing block 4 is damaged, a new fixing block 4 can be replaced by sliding and disassembling between the second clamping block 63 and the second clamping groove 62.

[0039] At least one supporting surface 9 is provided on both sides of the pressure strip 2 and the side of the fixing block 4 close to the pressure strip 2 . The module 3 is arranged on the plane formed by the supporting surface 9 on the pressure strip 2 and the supporting surface 9 of the fixing block 4 .

[0040] See also Figure 4 and Figure 5As shown, the module 3 is supported by a plane formed by the supporting surface 9 on the pressure strip 2 and the supporting surface 9 on the fixed block 4, that is, the module 3 is placed on the plane, and each fixed block 4 and the pressure strip 2 have at least one supporting surface 9. In the present embodiment, each fixed block 4 and the pressure strip 2 has two supporting surfaces 9 distributed from top to bottom, that is, it can carry two modules 3 for the glue pouring and curing process, which greatly improves the efficiency. In other embodiments, other numbers of supporting surfaces 9 can also be used. The specific number is not limited here, and can be selected according to actual needs.

[0041] The first card slot 52 is in a "convex" shape, and the second card slot 62 has the same shape as the first card slot 52. The first card slot 52 and the second card slot 62 can also be in a dovetail groove or other shapes. In other embodiments, the first card slot 52 and the second card slot 62 can also be in other shapes. The specific shapes are not limited here and can be selected according to needs.

[0042] like Figures 6 to 9 The second embodiment shown:

[0043] The present embodiment is different from the above-mentioned embodiment in that the first sliding clamping structure 5 can be replaced by a threaded locking structure 7, the threaded locking structure 7 includes a first step hole 72 penetrating through the bottom surface of the curing frame 1, a threaded hole 71 with an internal thread is provided on the bottom surface of the pressure strip 2, a bolt 73 is threadedly connected in the hole position formed by the threaded hole 71 and the first step hole 72, and a first spring 74 is sleeved on the outer surface of the threaded end of the bolt 73.

[0044] See also Figures 6 to 9 As shown, in the present embodiment, in order to prevent the pressure strip 2 from tilting and moving, a bolt 73 is passed through the first step hole 72 and is threadedly connected to the threaded hole 71 at the bottom of the pressure strip 2, thereby fixing the position of the pressure strip 2, making the bottom surface of the pressure strip 2 fit tightly with the upper surface of the curing frame 1, thereby preventing the pressure strip 2 from tilting, ensuring the horizontality of the module 3, and meeting the actual production needs. In order to prevent the bolt 73 and the threaded hole 71 from loosening due to vibration during use, thereby causing the pressure strip 2 to tilt, a first spring 74 is sleeved on the outer surface of the threaded end of the bolt 73, so that the first spring 74 is located between the step surface of the first step hole 72 and the screwing end of the bolt 73, and the bolt 73 is pre-tightened to reduce the risk of the threaded end of the bolt 73 being detached from the threaded hole 71.

[0045] like Figures 10 to 12 Embodiment 3 shown:

[0046] The difference between this embodiment and the above embodiment is that the first sliding clamping structure 5 can be replaced by an elastic pressing structure 8, which includes a second step hole 81 that penetrates through the bottom surface of the curing frame 1, and a mounting hole 82 is penetrated from top to bottom on the upper surface of the pressure strip 2. A ejector pin 83 is arranged in the hole formed by the mounting hole 82 and the second step hole 81, and an avoidance groove 88 is arranged on the top of the pressure strip 2. A limiting plate 84 that is adapted to the second step hole 81 is fixedly arranged on the bottom surface of the ejector pin 83, and a second spring 87 is sleeved on the outer surface of the bottom of the ejector pin 83. The second spring 87 is located between the limiting plate 84 and the step surface of the second step hole 81, and a pin hole 85 is transversely arranged on the top of the ejector pin 83. When installed, a pin 86 is arranged inside the pin hole 85. The length of the pin 86 is greater than the diameter of the ejector pin 83, so that it is clamped on the bottom surface of the avoidance groove 88.

[0047] See also Figures 10 to 12 As shown, in this embodiment, during installation, the second spring 87 is first sleeved on the bottom of the outer surface of the ejector pin 83, so that the ejector pin 83 passes through the second step hole 81 to the mounting hole 82. At this time, the second spring 87 is located between the limiting plate 84 and the step surface of the second step hole 81. When the ejector pin 83 penetrates into the mounting hole 82, the elastic force of the second spring 87 is overcome to make the pin hole 85 in the avoidance groove 88, and then the pin 86 is inserted into the pin hole 85 to realize the clamping connection between the pin 86 and the avoidance groove 88, so as to limit the position of the ejector pin 83, thereby preventing the ejector pin 83 from separating from the mounting hole 82 and realizing the fixation between the ejector pin 83 and the pressure strip 2. When tilting occurs, the elastic force of the second spring 87 gives the ejector pin 83 a downward force, thereby driving the bottom surface of the pressure strip 2 to be in close contact with the upper surface of the curing frame 1, preventing the pressure strip 2 from tilting, and ensuring the flatness of the silicone curing of the module 3.
