Description

Technical Field

[0001] The utility model relates to the technical field of LED lamp bead processing, in particular to a fixture for packaging LED lamp beads. Background Art

[0002] Dispensing glue for DIP LEDs is a crucial step in the packaging process. The dispensing system is primarily used to inject encapsulation material (such as epoxy or silicone) around the LED chip and its pins to protect the LED chip and optimize its optical performance.

[0003] Glue dispensing for LED lamp beads plays a crucial role in the encapsulation process, improving their reliability and performance. Encapsulation materials (such as epoxy or silicone) protect the LED chip from environmental influences, including moisture, dust, and chemical corrosion. Furthermore, the encapsulation material provides a robust protective layer, increasing the mechanical strength of the LED and preventing damage from physical shock or vibration during use.

[0004] The shape and refractive index of the packaging material can affect the light output characteristics of the LED. By adjusting the shape and thickness of the packaging material, light can be diffused more evenly, improving light uniformity. Optimizing the refractive index of the packaging material allows more light to be effectively emitted from the LED chip, improving light efficiency. For white light LEDs, the packaging material can also contain phosphors, which convert some blue light into other colors, thereby mixing to produce white light.

[0005] After the existing direct-plug LED lamp beads are packaged, the pins on the lamp beads are usually directly pulled by a cylinder, and the LED chip and the package body are pulled out of the mold, thereby achieving the effect of separating the package body from the mold. However, during the pulling process, since the pins are usually slender metal strips, some of the pins are easily broken during the pulling process, which in turn affects the subsequent inspection and use of the LED lamp beads. Therefore, in order to solve the above-mentioned technical problems, the utility model proposes a fixture for LED lamp bead packaging. Utility Model Content
