Abstract

A nozzle cleaning device includes a cleaning liquid outlet (40a) to which a nozzle (20) is attached, and another cleaning liquid outlet (40b) to which a cleaning attachment (50) is attached. A cleaning accessory (50) comprises a nozzle cover (51) and a cleaning support (52) installed on the nozzle cover (51). A cleaning chamber (64) is formed in the nozzle cover (51). A cleaning liquid inflow chamber (71), an external cleaning liquid discharge port (72), and a cleaning liquid discharge hole (73) are formed in the cleaning holder (52). The cleaning liquid jetted from the nozzle (20) in the first direction (A1) and the cleaning liquid jetted from the external cleaning liquid jetting unit (72) to the nozzle (20) in the second direction (B) collide with each other in the vicinity of the discharge unit (23) in the cleaning chamber (64).

Description

technical field [0001] The present invention relates to a nozzle cleaning device that cleans a nozzle that applies a discharge substance such as an adhesive to a coating target object. Background technique [0002] In order to apply a discharge substance such as an adhesive to a coating target object, in some cases, a coating device (dispenser) having a nozzle is used. Examples of discharge substances are sticky adhesives and pasty conductive materials. The discharge material is pressurized and pushed out from the tip opening of the nozzle to coat the discharge material onto the coating target object. The pressure of the discharged substance (coating pressure) during coating of the discharged substance is set according to the viscosity of the discharged substance and the like, and may reach several hundreds of kilopascals (kPa) in some cases. [0003] After using the nozzle, the nozzle will be cleaned and the discharge material adhering to the nozzle will be removed. It i...
