Description

Needle washing apparatus for dispensing

The present invention relates to a washing device for dispensing needle, and more particularly, after dispensing the coating liquid using a dispensing gun at the end where the LCD panel and the TAB (tape automated boning) IC meets The present invention relates to a cleaning device for a needle for dispensing, which can perform a continuous operation by removing a coating liquid remaining on a needle of a fencing gun by spraying a high pressure with a cleaning agent and air.

In general, an LCD includes an LCD panel having a lower substrate in which pixels are arranged in a medlix and an upper substrate on which a color filter is formed, with a liquid crystal interposed therebetween. A drive IC is provided for applying a voltage to each pixel array on the matrix and supplying a signal for driving the liquid crystal. Drive IC and LCD panel are connected and bonded. Here, the device is formed by integrating the drive IC, the control circuit for controlling the LCD panel and the drive IC, and the bus line or the backlight.

A method of bonding the LCD panel and the drive IC for forming the above-described device will be briefly described. First, a thin film transistor (TFT), a lower substrate, an upper substrate, and an LCD panel having a lower substrate and an upper substrate bonded to each other with a liquid crystal are prepared. In this case, driving pins for driving respective gate lines and data lines formed on the lower substrate are exposed at the edge portion of the lower substrate. In addition, a printed circuit board and a data board are provided to apply an electrical signal to the gate line and the data line spaced apart from the LCD panel.

The above-described printed circuit board and data board are connected to the driving pins of the lower board by tape automated boning (TAB). At this time, the TAB is equipped with a drive IC, a plurality of leads are provided on both sides of the TAB, one pin is bonded to the driving pin of the LCD panel, the other pin is bonded to the printed circuit board and the data substrate. At this time, in order to prevent the short (short) from occurring in the subsequent process on the part where the driving pin of the LCD panel is in contact with the lead of the TAB and to prevent the deterioration of the contact characteristics between the lead of the TAB and the driving pin, the driving pin and the lead are Dispensing is formed in the contacted portion. This dispensing is discharged and cured by a predetermined amount through the needle of the injection device in which the liquid coating liquid is contained.

However, the coating liquid remains between the driving pin and the lead outside the needle of the above-described injection device. Thus, the coating liquid remaining on the needle (hard) had a problem that hardening occurs under a state exposed to room temperature within a long time or a short time has a big influence on the next operation.

The present invention has been made to solve the above conventional problems, the object of the present invention is to apply a coating liquid using a dispensing gun (dispensing gun) at the end where the LCD panel and the TAB (tape automated boning) IC meets It is to provide a cleaning device for the dispensing needle for dispensing needle can improve the working efficiency can be performed by continuous operation by removing the coating liquid remaining in the needle (needle) of the dispensing gun after high pressure injection of the cleaning agent and air .
