Description

Technical Field

[0001] The utility model relates to the technical field of LED product powder glue stirring devices, in particular to a LED product powder glue stirrer. Background Art

[0002] With the progress of the times and the development of technology, LED lamps have become the most commonly used lamps. In the production process of LED lamps, encapsulation glue is required to perform the dispensing step, and light source materials such as phosphors need to be added to the encapsulation glue used, so the encapsulation glue must be fully mixed and evenly mixed.

[0003] At present, the existing stirring devices usually use the centrifugal force generated by the rotation of the stirring shaft to evenly disperse the phosphor, but it is not enough to make all the fine phosphor particles evenly dispersed in the glue. There is still agglomeration of some fine particles, and the mixing effect is often poor. At the same time, the mixing efficiency is low, and the agglomerated granular phosphor is easier to precipitate in the glue, so it is easy to cause the color temperature and color coordinates of the product to drift. This causes the LED products made with the fluorescent glue that is not evenly stirred to have a wider color temperature distribution and a messy color, which greatly affects the production quality of the LED products. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a powder glue stirrer for LED products, which is used to solve the problem of phosphor powder particle agglomeration and poor mixing effect during the stirring process of packaging glue and phosphor powder in the existing stirring device.

[0009] Optionally, a bracket assembly is further included, wherein the bracket assembly includes a first bracket and a second bracket, wherein the first bracket is used to install the first stirring component, and the second bracket is used to install the driving component.

[0012] Optionally, the support rods are locked with bolts, and a mounting hole for passing the first stirring component is provided on the support rod, and the first stirring component is interference fit with the mounting hole.

[0013] Optionally, the second bracket includes a first mounting segment and a second mounting segment, and an included angle β at a connection between the first mounting segment and the second mounting segment is 45° to 150°.

During the rotation of the mixing container 1, the resistances exerted by the first stirring member 301 and the second stirring member 302 on the powder glue solution are the same in the circumferential direction of the mixing container 1, but are opposite in the radial direction of the mixing container 1. In the radial direction, the first stirring member 301 and the second stirring member 302 cooperate to exert a shear force on the phosphor particles in the powder glue, which can effectively disperse the phosphor particles in the powder glue, thereby avoiding uneven precipitation of the phosphor in the powder glue due to uneven particle size, thereby effectively avoiding the deviation of the color temperature and color coordinates of the product, thereby effectively improving the production quality of LED products.

[0028] In an exemplary embodiment of the present application, a bracket assembly 4 is further included. The bracket assembly 4 includes a first bracket 401 and a second bracket 402 . The first bracket 401 is used to install the first stirring component 301 , and the second bracket 402 is used to install the driving component 2 .

[0033] In this embodiment, the support rod 401c and the support rod 401b are locked and fixed by bolts 5, and the first stirring member 301 is interference fit with the mounting hole opened on the support rod 401c, so that the first stirring member 301 can be fixedly set on the support rod 401c.

[0035] In this embodiment, an angle of 45° to 150° is set at the connection between the first mounting section 402a and the second mounting section 402b, so that a triangle is formed between the second bracket 402 and the horizontal plane, which can be relatively stably set on the ground and can ensure that the driving component 2 is in an inclined state after installation with the first mounting section 402a or the second mounting section 402b.

[0036] In an exemplary embodiment of the present application, both the first mounting section 402a and the second mounting section 402b are provided with through holes.

[0037] In an exemplary embodiment of the present application, a transmission shaft 6 is provided on the mixing container 1 , and the transmission shaft 6 passes through the through hole and is connected to the output shaft of the driving component 2 .

[0038] It is worth mentioning that the through hole is used to penetrate the transmission shaft 6, one end of the transmission shaft 6 is fixedly connected to the mixing container 1, and the other end is connected to the output shaft of the driving component 2. The driving component 2 provides driving force, and the mixing container 1 is driven to rotate through the transmission shaft 6. Since the first mounting section 402a is inclined relative to the horizontal plane, the mixing container 1 can be inclined relative to the horizontal plane.

[0039] In an exemplary embodiment of the present application, the driving component 2 is disposed on the first mounting section 402 a .

[0040] In an exemplary embodiment of the present application, a driving component 2 is provided on the first installation section 402a and the second installation section 402b, and each driving component 2 drives a mixing container 1 to rotate.

[0043] In this embodiment, the grinding beads are the second stirring components 302 movably disposed in the accommodating chamber 101. The grinding beads move in the opposite direction to the rotation direction of the mixing container 1 under the action of gravity, thereby providing reverse resistance to the powder glue solution along the rotation direction of the mixing container 1, and forming a shear force between the first stirring component 301 in the radial direction, so that the particles in the powder glue can be dispersed.

[0044] Working principle: the mixing container 1 is a cylindrical barrel container with an opening at one end, and the mixing container 1 is tilted, the glue and the fluorescent powder are loaded into the accommodating chamber 101 of the mixing container 1, and the first stirring component 301 is extended from the opening of the mixing container 1, and the first stirring component 301 is suspended in the accommodating chamber 101 and close to the higher side of the mixing container 1, the first stirring component 301 is fixed, and the second stirring component 302 is movably placed in the accommodating chamber 101. When the stirrer stops, the second stirring component 302 stays on the lower side of the mixing container 1 under the action of gravity. Since the driving component 2 is connected to the mixing container 1, and the driving component 2 is connected to the mixing container 1, the driving component 302 is moved to the lower side of the mixing container 1. The mixing container 1 is driven to rotate. During the rotation of the mixing container 1, the resistances exerted by the first stirring member 301 and the second stirring member 302 on the powder glue solution are the same in the circumferential direction of the mixing container 1, but are opposite in the radial direction of the mixing container 1. In the radial direction, the first stirring member 301 and the second stirring member 302 cooperate to exert a shear force on the phosphor particles in the powder glue, which can effectively disperse the phosphor particles in the powder glue, thereby avoiding uneven precipitation of the phosphor in the powder glue due to uneven particle size, thereby effectively avoiding the deviation of the color temperature and color coordinates of the product, thereby effectively improving the production quality of LED products.
