Problems solved by technology

However, fluorescent glue contains phosphor solid particles that are insoluble in silica gel, and the phosphor will precipitate during dispensing. The longer the dispensing time, the more phosphor will be deposited at the bottom of the dispensing cylinder, resulting in low dispensing efficiency and poor fluorescent glue. The waste directly increases the cost of materials and production

Abstract

The invention discloses an LED packaging precipitation preventing device, a precipitation preventing control method and an LED dispenser. The precipitation preventing device comprises a rotation valve, a rotation rod, a first motor, a glue pushing rod, a second motor and a controller, wherein the rotation valve and the rotation rod are used for controlling the rotation of a fluorescent glue barrel; the first motor is used for controlling the rotation rod, the rotation valve and the fluorescent glue barrel to rotate synchronously; the glue pushing rod is used for pushing fluorescent glue; the second motor is used for driving the glue pushing rod to push the glue; the controller is used for controlling working states of the first motor and the second motor; during dispensing, the first motor is used for driving the rotation rod and the rotation valve to rotate coaxially, so that the fluorescent glue barrel can be in a rotation state all the time in the dispensing process, precipitates can not be generated, the fluorescent glue can not be wasted, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an anti-precipitation device for LED packaging, an anti-precipitation control method and an LED dispensing machine. Background technique [0002] Existing LED packaged white light products mainly include Lamp (in-line), SMD (surface mount device), COB (chip on board), high power imitation lumen, integrated high power, etc. The white light manufacturing process requires a fluorescent glue process. [0003] During the dispensing work, the operator needs to manually pour a certain amount of fluorescent glue into the dispensing tube for dispensing, and then manually add fluorescent glue into the dispensing tube again after a tube of fluorescent glue is dispensed. However, fluorescent glue contains phosphor solid particles that are insoluble in silica gel, and the phosphor will precipitate during dispensing. The longer the dispensing time, the more phosphor will be deposited at the bott...
