LED substrate centrifugal device and using method thereof

Abstract

The invention discloses an LED substrate centrifugal device and a using method thereof. The device comprises a first fixing device, a second fixing device and a lower pressing plate; the two ends of the first fixing device are provided with two parallel side baffles, one or more than one pressing strip are uniformly arranged between the two side baffles, and the pressing strips and the side baffles are arranged in parallel; one surfaces, close to the pressing strips, of the side baffles are provided with first grooves, wherein the first grooves are parallel to the long edges of the side baffles; the long edges of the side baffles and the long edges of the pressing strips are integrally formed through spring strips; the second fixing device is used for fixing the first fixing device on theinner side wall of a roller of a centrifugal machine; the two ends of the lower pressing plate are provided with fixing buckles extending downwards; and the lower pressing plate is located above the first fixing device, and the long edge of the lower pressing plate is parallel to the long edges of the side baffles. The invention further discloses a using method of the LED substrate centrifugal device. According to the LED substrate centrifugal device, COB semi-finished products on an LED substrate can be attached to the inner side wall of the roller, and the production efficiency and the yieldcan be improved.

Description

technical field [0001] The invention relates to LED packaging technology, in particular to an LED substrate centrifugal device and a using method thereof. Background technique [0002] Centrifugal sedimentation machine is a hot spot for LED packaging dispensing process in the past year. It aims to achieve a simple and reasonable structure, simple and fast operation, high production efficiency, and can solve the problem of poor light color consistency caused by inconsistent sedimentation of phosphor particles during LED packaging. The problem. The core of its design is that the centrifugal sedimentation machine includes a body, a control device installed on the body, a motor installed in the body and connected to the control device, a drum installed in the body with a cavity inside, and a drum located at the center of the drum. The roller is connected with the motor and can drive the roller to rotate. The inner wall of the cavity of the roller is provided with a number of ma...

AI Technical Summary

Problems solved by technology

Because the size of the light-emitting surface of COB products is large (generally, the diameter of the light-emitting surface is > 3mm), and the continuous piece is an aluminum LED substrate structure, which is difficult to bend, such as figure 1 As shown, the use of existing centrifugal equipment will lead to uneven stress on the fluorescent glue of different products in the COB contiguous piece, resulting in uneven phosphor powder of some products in the same contiguous piece, and the product is scrapped
