Embodiment 1

[0029] Please refer to Figure 1 to Figure 4 , the first embodiment of the present invention is:

[0030] A glue dispensing head is installed on a glue dispensing device and is used for dispensing LED lamp beads in a glue dispensing process.

[0031] The dispensing head includes: a rubber tube 100 and a bracket 200 that are connected to each other; the rubber tube 100 is provided with a number of shunt channels inside; The sorting structure of the runner, the sorting structure is connected to the corresponding runner, and is arranged at the glue inlet of the corresponding runner.

[0032] In this embodiment, the structural principle of the glue dispensing head is as follows: mixed fluorescent glue enters the bracket 200 , some small-sized phosphor powders are screened out through the sorting structure, and the glue is discharged through the corresponding shunt channel , while the other mixed phosphors are discharged through the other said shunt channels, so as to effectively...

Embodiment 2

[0044] The glue outlet of the existing glue dispensing head adopts a flush circular glue outlet hole, which leads to the phenomenon of glue pulling and glue flowing easily during the glue dispensing process. In addition, the number of apertures of different sizes of the glue outlet hole is too large. , resulting in frequent replacement in the normal process, which seriously affects the production efficiency.

[0045] In this embodiment, a dispensing head is provided, including: a rubber tube 100 and a bracket 200 connected to each other; a plurality of shunt channels are arranged inside the rubber tube 100; The phosphor powder is screened to part of the sorting structures of the sub-flow channels, the sorting structures are connected to the corresponding sub-flow channels, and are arranged at the glue inlets of the corresponding sub-flow channels. Further, the glue outlet of the rubber tube 100 is provided with a notch 160 penetrating the pipe wall, and the notch 160 divides t...

Embodiment 3

[0050] This embodiment discloses a glue dispensing device, which includes the glue dispensing head according to any one of the above-mentioned embodiments, and further includes a frame, a positioning assembly for placing a product to be dispensed, and a glue dispensing device for making the glue dispensing The head moves to the moving assembly above the positioning assembly; the product positioning mechanism is fixedly connected to the frame, the moving assembly is movably connected to the frame, and the dispensing head is installed on the moving on the component.

[0051] In this embodiment, during the dispensing process, the LED workpiece to be dispensed is placed on the positioning component, and the dispensing head is moved to the corresponding LED workpiece to be dispensed by the moving component, so as to Dispensing.

[0052] To sum up, in the dispensing head and dispensing device provided by the present invention, when the mixed fluorescent glue enters the bracket, par...

Abstract

The invention discloses an adhesive dispensing head and an adhesive dispensing device. The adhesive dispensing head comprises an adhesive tube and a bracket which are connected with each other, a plurality of sub-runners are arranged in the rubber pipe; a sorting structure used for screening part of fluorescent powder with small particle sizes to part of the sub-runners is arranged in the support, and the sorting structure is connected with the corresponding sub-runners and arranged at glue inlets of the corresponding sub-runners. By arranging the sorting structure, part of small-particle-size fluorescent powder is screened to the corresponding sub-runners, glue is independently discharged through the corresponding sub-runners, other mixed fluorescent glue is discharged through other sub-runners, the falling point positions of the fluorescent powder with different particle sizes can be effectively controlled, and the fluorescent powder quality is improved. The consistency of the drop point positions of the CIE color coordinates of the lamp beads is improved, and meanwhile the brightness of the LED lamp beads is improved.

Description

technical field [0001] The invention relates to the technical field of glue dispensing, in particular to a glue dispensing head and a glue dispensing device. Background technique [0002] With the continuous development of light-emitting diodes (Light Emitting Diodes, LEDs), their manufacturing processes are becoming more and more mature, and at the same time, the requirements for the yield and quality of LEDs are getting higher and higher. In the production process of LED lamp beads, it is necessary to perform fluorescent glue dispensing on the LED chip. The fluorescent glue in the existing dispensing method includes mixed phosphors, and the dispensing equipment cannot well control the placement of phosphors with different particle sizes. As a result, the CIE color coordinates of the finished LED lamp beads have poor consistency, cannot meet the CIE standard, and the luminous brightness is insufficient. SUMMARY OF THE INVENTION [0003] The technical problem to be solved...
