Abstract

The invention relates to a dispensing valve needle cleaning and wiping mechanism. The mechanism comprises a bottom plate and a non-dust cloth roll; the bottom plate is connected with a discharging winding drum, a material collecting winding drum, an alcohol titration valve and a clamping wiping mechanism, the material collecting winding drum is connected with a servo motor, and a plurality of guide rollers are arranged between the discharging winding drum and the material collecting winding drum; the non-dust cloth roll is detachably connected to the discharging winding drum, one end of the non-dust cloth roll is guided by the plurality of guide rollers, and sequentially passes the alcohol titration valve and the clamping wiping mechanism to be connected with the material collecting winding drum; and the clamping wiping mechanism comprises a Y-shaped clamping jaw air cylinder, the two sides of the Y-shaped clamping jaw air cylinder are provided with special-shaped blocks correspondingly, and V-shaped guide holes are formed in the special-shaped blocks. The dispensing valve needle cleaning and wiping mechanism adopts a mode of the non-dust cloth roll rolling a material to realize feeding, and is matched with a cleaning mode of the alcohol titration valve dropping alcohol and the clamping air cylinder clamping the needle to clean a needle valve needle, the dispensing valve needlecan be automatically cleaned, residual glue on the dispensing valve needle can be effectively cleaned, and continuous dispensing effect is guaranteed.

Description

technical field [0001] The invention relates to the field of wiping the needle of a dispensing valve, in particular to a cleaning and wiping mechanism for a needle of a dispensing valve. Background technique [0002] In the LCD panel manufacturing industry, the dispensing process is a necessary and important link. The types of dispensing include blue glue, UV glue, silver glue and so on. Each type of dispensing has different characteristics and functions. Now the manufacturing dispensing process is automatic dispensing, but if the dispensing needle cannot be cleaned effectively, it will affect the subsequent dispensing effect. [0003] At present, on general dispensing equipment or dispensing stations, the residual glue on the dispensing needle valve head is basically wiped with a dust-free cloth sprayed with alcohol, and then replaced manually when it is almost dirty. Wipe on the dust-free cloth all the time in this way, and replace it manually after being dirty. The clea...
