Description

Technical Field

[0001] The present invention relates to a stirring device, and more particularly to a three-axis all-round planetary mixing and stirring device. Background Art

[0002] The main optical parameters of CHIP type light emitting diodes include color temperature (color region), brightness, emission angle, etc. Since it is a board-mounted planar moding packaging structure, the emission angle and brightness will not change after the primary optical design (moding). Before moding, in order to produce white light with different color temperatures, "powder glue" mixing is carried out according to different ratios of powder glue (epoxy resin powder glue) and phosphor, and then pressed into a "glue cake". And the mixing method of the powder glue plays a key role in the consistency of the color temperature (color region). To achieve uniform mixing of the powder glue both macroscopically and microscopically, it is required that the container rotates to make the powder perform repeated movements such as flowing, diffusing, counteracting, and folding, so that the powders are mixed and penetrated with each other, thereby achieving the purpose of uniform macroscopic mixing of the powders; it is also required to use the moving blades in the container to forcibly stir and shear the powders repeatedly, constantly breaking the adjacent relationship between the powder particles microscopically, and allowing the powder particles to move and exchange fully, achieving refined mixing of the materials microscopically. To achieve perfect mixing both macroscopically and microscopically, it is required to organically combine these two types of mixing movements to jointly improve the uniformity of powder mixing.

[0003] Currently, in the production of the glue cake of CHIP type light emitting diodes, the powder glue mixing method mostly adopts single-axis stirring mixing or manual stirring mixing. Compared with other solid powders, the powder glue used for CHIP type light emitting diodes has a smaller particle size (micrometer level) and is more sensitive to temperature during the mixing process. Single-axis stirring is that there is a stirring shaft driven by a motor in a container tank, with stirring blades attached, for single-axis mixing and stirring. The phosphor and powder glue in the powder tank are mixed during the uniform rotation of the stirring shaft. The disadvantage is that the samples in the dead corners of the tank body cannot participate in the mixing, and precipitation and stratification are likely to occur. Manual stirring is the same as single-axis stirring, but the stirring shaft is replaced by a manual stirring rod. The advantage is portability, and there is no requirement for the minimum amount of phosphor and powder glue to be stirred, and there will be no phenomenon that the samples in the dead corners of the tank body cannot participate in the mixing. The disadvantage is that the stirring is not uniform.

[0004] In summary, the present invention designs a three-axis all-round planetary mixing and stirring device. Summary of the Invention

The large disk 3 is arranged on the turning mechanism 5, and four powder tank fixing devices 4 are arranged on the large disk 3. The bottom of the powder tank fixing device 4 is connected to a self-rotating motor, and the large disk 3 is connected to a revolving motor. The revolving motor and the self-rotating motor rotate in opposite directions. One side of the turning mechanism 5 is connected to a turning motor through a gear transmission mechanism 6. The self-rotating motor, the revolving motor and the turning motor are all connected to a PLC controller 9.

[0020] The body shell 1 of this specific embodiment is made of high-strength stainless steel material, and a sound insulation and heat insulation layer is arranged inside to reduce noise and heat transfer and improve the safety of the operating environment. A transparent protective cover 7 is arranged on the top of the shell 1, which is convenient for observing the mixing process and ensuring operation safety at the same time. The planetary mixing device 2 is located inside the body shell 1 and includes a large disk 3, a powder tank fixing device 4 and a turning mechanism 5. The large disk 3 is connected to the body shell 1 through the turning mechanism 5. One side of the turning mechanism 5 is connected to a turning motor through a gear transmission mechanism 6 to realize the 360° turning of the large disk 3. Four powder tank fixing devices 4 are evenly distributed on the large disk 3. The bottom of each powder tank fixing device 4 is connected to a self-rotating motor to realize the self-rotation movement of the powder tank. A valve mechanism 8 for locking the powder tank is arranged on the powder tank fixing device 4 to ensure that the powder tank will not loosen during high-speed rotation. The self-rotating motor adopts a high-precision servo motor to ensure the stability and accuracy of the self-rotation of the powder tank. The revolving motor is connected to the large disk 3 to drive the large disk 3 to perform a revolving movement.
