Problems solved by technology

The advantages of this manufacturing method are lower cost, less packaging material, and waterproof performance. However, its disadvantage is that the PCB board itself cannot be flatly discharged in the receiving groove, which causes the PCB board to be distorted and arranged in the finished product. In flexible light strips, it looks very unattractive
The most conventional method is to wrap the PCB directly through the packaging material, which has a very good waterproof effect, but still cannot make the PCB boards neatly arranged in the flexible light strip

Embodiment Construction

[0018] figure 1 A schematic view of the mold according to the present invention is shown, as can be seen from the figure, the mold 1 has a filling groove 2, and fixed brackets designed as U-shaped brackets 6 and made of flexible materials are arranged at intervals in the filling groove 2 middle. These U-shaped supports 6 are fixedly held in the filling tank 2, and this is achieved by designing the width of the U-shaped supports 6 to be slightly greater than the width of the filling tank 2. In this case, since the U-shaped supports 6 are formed by Made of flexible material, its own elasticity allows the U-shaped bracket 6 to snap into the filling groove, that is, to snap into the filling groove with an interference fit, so as to ensure that the U-shaped bracket 6 will not move against the mold 1 A position shift occurs. At the same time, it can be seen from the figure that the height of the U-shaped bracket 6 is less than or equal to the depth of the filling groove 2, so that...

Abstract

The invention relates to a packaging method for light strips, the method has the following steps: a) providing a mold (1) with a filling groove (2); into the slot (2); c) holding the printed circuit board (4) equipped with the light-emitting component (3) in a fixed position in the fixed bracket; d) filling the packaging material (5) into the filling slot (2) neutralizing and curing the encapsulation material (5); e) removing the mold (1). The light bar manufactured by the above method has a good appearance, and the printed circuit boards disposed therein are regularly arranged in the finished light bar, and the light bar also has very good waterproof performance.

Description

technical field [0001] The invention relates to a packaging method for a light bar. Background technique [0002] Flexible light strips are usually widely used in outdoor environments, such as for contour lighting of buildings, dome lighting and so on. Usually this type of light bar is slender and flexible so that it can be simply bent into any shape, and this light bar also meets the requirements of IP65 or a higher IP rating for outdoor use. In fact, the structure of the flexible light bar is very simple. The flexible PCB is embedded in a flexible and transparent glue. However, the difficulty in manufacturing such flexible light strips lies in the potting process. [0003] A method for manufacturing a flexible light bar is disclosed in the prior art. In this method, the potting material is directly potted on the flexible PCB board provided with LED components. The advantage is that the process is simple and the cost is low. cost. However, its disadvantages are also ve...
