Description

Technical Field

[0001] The utility model belongs to the technical field of semiconductor LED devices, and particularly relates to a novel dispensing structure. Background Art

[0002] In the traditional SMD LED packaging process, single-hole dispensing is one of the commonly used chip fixing methods. This method fixes the LED chip on the carrier area of the bracket by precisely controlling the amount of packaging glue, so as to ensure good electrical contact and thermal contact between the chip and the bracket.

[0003] However, in traditional SMD packaging, especially in the packaging process of light source devices such as LEDs, a single-hole dispensing structure is often used to fix the chip and the bracket. Single-hole dispensing requires precise control of the glue amount at each point, and the operation process is cumbersome, resulting in low overall packaging efficiency. Different shapes and sizes of brackets have different requirements for the dispensing position and amount, and it is difficult for single-hole dispensing to adapt to all types of brackets, which limits its application range. Too much or too little amount of packaging glue will affect the contact effect between the chip and the bracket, and thus affect the overall performance and quality stability of the product. Therefore, it needs to be improved by the staff. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a novel dispensing structure to solve the problems mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] (1) Through the settings of the mounting sleeve frame, mounting pipes, sealing rings, sealing covers, threaded columns and dispensing needles, during use, the sealing covers or threaded columns are threadedly mounted on the inner walls of the four mounting pipes. The mounting pipes can be sealed through the sealing covers, the dispensing needles are mounted through the threaded columns, and the tail end of the threaded column abuts against the sealing ring on the surface of the baffle.

When the clamping rod on the surface of the drive rod reaches the position of the limiting hole, the compression spring pops out the clamping rod, thereby inserting the clamping rod into the limiting hole, which can facilitate the convenient fixation between the drive rod and the installation disk. By driving the installation disk and the dispensing mechanism at the bottom by the drive rod to adjust the angle, when the staff presses the pressing plate into the installation disk, the pushing plate at the front end of the connecting rod can be moved, so that the pushing plate squeezes the clamping rod in the limiting hole into the drive rod, which facilitates pulling out the drive rod from the installation hole of the installation disk, thus achieving the effect of conveniently adjusting the angle of the dispensing mechanism and facilitating the disassembly and assembly of the rotating mechanism.

[0020] (3) Through the settings of the installation sleeve frame, assembly pipe, connecting pipe and storage pipe, during use, connecting pipes are arranged around the area where the assembly pipe is inserted into the installation sleeve frame. Glue is conveyed into the four storage pipes through the four connecting pipes respectively. Thus, the four storage pipes can discharge the glue through the four dispensing needles, achieving the effect of convenient glue conveyance and facilitating the operation of the staff.
