Multifunctional COB (chip on board) automatic dispenser

Abstract

The invention discloses a multifunctional COB (chip on board ) automatic dispenser comprising a dispensing controller and two multifunctional dispensing heads. The multifunctional COB automatic dispenser is characterized in that a fixture table is mounted on the dispensing controller which is provided with a bracket; an X-axis movement mechanism installed with a Z-axis movement mechanism is arranged on the bracket; the Z-axis movement mechanism is provided with a lifting skateboard; the two multifunctional dispensing heads are all mounted on the lifting skateboard; the X-axis movement mechanism comprises an X-axis motor, an X-axis screw rod and an X-axis guide rail; the X-axis motor is arranged on one side of the bracket; the X-axis screw rod is in parallel arrangement with the X-axis guide rail which is provided with a moving flange; the moving flange is fixedly connected with the X-axis screw rod; the X-axis screw rod is connected with the X-axis motor. The multifunctional COB automatic dispenser has the advantages of realizing the multifunctional work of the dispenser, guaranteeing the spraying of glue and phosphor to be completed in the same device, reducing installation time and improving dispensing efficiency.

Description

technical field [0001] The invention relates to a COB automatic dispensing machine with multiple functions of multi-dispensing heads. Background technique [0002] In industrial production, dispensing machines are widely used in many fields such as semiconductors, electronic components, and LED manufacturing, and are suitable for dispensing requirements required by automated production lines that support high-tech industries. Traditional dispensing machines use manual dispensing, which has complex operation process, low efficiency, low precision and is difficult to meet the dispensing requirements of complex graphics. With the rapid development of industrial automation, automatic dispensing machines have begun to replace traditional dispensing machines, which can realize production automation and improve production efficiency and processing accuracy. [0003] As one of the most important components in LED manufacturing, the COB substrate is arrayed with multiple chips, whic...

Problems solved by technology

At present, the dispensing machines used in the industry have single functions, and it is difficult to meet the requirements of continuous multiple dispensing of products. The usual solution is to use multiple dispensing machines to dispense glue sequentially.

There are a series of problems in this method. Multiple dispensing not only increases the number of workpiece clamping, introduces clamping errors, but also increases non-processing time such as workpiece clamping and reduces processing accuracy.
