[0002] With the rise of my country's LED industry, the demand for LED packaging dispensing machines in the LED industry is increasing, and the precision is getting higher and higher. The control accuracy reaches one ten thousandth of a milliliter, while the traditional pneumatic dispensing valve is vulnerable Influenced by factors such as air pressure and colloid viscosity changes, the above accuracy cannot be met at all, and it is not convenient to disassemble and clean

The invention relates to a high-accuracy adhesive dispensing valve for packaging a light emitting diode (LED) in an adhesive dispensing way. The adhesive dispensing valve comprises a connecting part which is fixedly arranged on the outer side face of a valve body, wherein a motor-driven injection rod is inserted into a slipway of the valve body from top to bottom; the rod head of the injection rod is protruded on the outer side of the slipway; the rod body of the injection rod is in sliding fit with the slipway; a sealing device matched with the rod body of the injection body is arranged at the upper end of the slipway; the slipway positioned on the lower side of the injection rod forms a closed valve cavity; the valve cavity is communicated with a liquid inflow channel in the connecting part; a liquid inflow joint communicated with a rubber pipe is arranged on the liquid inflow channel in the connecting part; a liquid discharging joint component communicated with a needle beak is arranged at the lower end of the valve body; and a valve core component which is used for communicating the valve cavity with the liquid discharging joint component or disconnecting the valve cavity fromthe liquid discharging joint component is also arranged in the valve body. The valve has a simple structure; the injection rod is used for discharging glue and is driven by a stepping motor, so that the glue can be discharged at high accuracy; simultaneously, the valve meets the requirements of production processes of LEDs and is convenient to detach and wash.
Description
technical field [0001] The invention belongs to the field of LED dispensing and packaging, and in particular relates to a high-precision dispensing valve for LED dispensing and packaging. Background technique [0002] With the rise of my country's LED industry, the demand for LED packaging dispensing machines in the LED industry is increasing, and the precision is getting higher and higher. The control accuracy reaches one ten thousandth of a milliliter, while the traditional pneumatic dispensing valve is vulnerable Influenced by factors such as changes in air pressure and colloidal viscosity, the above precision cannot be met at all, and it is also inconvenient to disassemble and clean. Contents of the invention [0003] The object of the present invention is to provide a high-precision dispensing valve, which has the advantages of high precision, convenient disassembly and cleaning. [0004] In order to achieve the purpose of the above invention, the technical solution a...
