A rotating shaft dispensing mechanism comprises a valve body, a spool, an injection rod, a dispensing needle, a dispensing chamber and a driving mechanism. The spool is circular in shape. The spool runs horizontally through the valve body and is driven by the driving mechanism. The upper end of the valve body is provided with a vertical dispensing channel. One end of the injection rod runs through the dispensing channel and slides in the dispensing channel, and the part of the valve body is located in the spool. The lower end of the upper dispensing channel corresponds to a vertical downward dispensing channel. The dispensing needle is evenly arranged at the bottom of the valve body and connected with the downward dispensing channel separately. The dispensing chamber is fixed on one side of the valve body, and the glue intake chamber is provided with a glue intake port, and the glue intake channel is connected with the glue intake chamber inside the valve body. The inner part of the valve core is provided with a T-type three-way channel, which enables the upper dispensing through rotating the valve core. The channel is connected with the lower dispensing channel or the feeding channel is connected with the upper dispensing channel. The utility model separates the two steps of gluing and dispensing by matching the valve body and the valve core, thus improving the dispensing accuracy and stability.

转轴点胶机构
本技术涉及点胶设备领域,尤指一种转轴点胶机构。
技术介绍
led点胶机也就是专业用来给led产品点胶的设备,随着点胶机技术的不断成熟,所能够应用的产品也在不断的增加,主要包括有电子照明行业、机械五金行业、汽车制造行业等多个生产领域。led专用设备,专用于发白光的led生产过程中的荧光粉点胶。由于led荧光粉的胶量要求非常精确,而气压式点胶机会随着气压大小的不同,胶量会发生较大的变化,所以气压式点胶机满足不了led行业的需求。目前市场上led行业用的基本都是计量式点胶机,其胶量精确度可以达到万分之一,能满足led荧光粉的点胶,但计量式点胶机大多结构复杂,这无疑增加了生产难度和生产成本。
