Description

Contactless Nozzle Clean Device The present invention relates to a nozzle cleaning device for removing contaminants accumulated in a nozzle. Generally, electronic devices are required to possess waterproofing capabilities. To implement this waterproofing, a waterproof section is formed during the manufacturing process by applying a potting solution using a nozzle to prevent moisture from penetrating into the substrate. For example, a receptacle connector in an electronic device is coupled to a substrate to perform functions such as charging and data transmission; waterproofing of the electronic device can be achieved by applying a potting solution using a nozzle to the area requiring waterproofing after the receptacle connector is coupled to the substrate. FIG. 1 is a schematic front view of a nozzle (100) for discharging potting fluid. As the process of applying the potting liquid is performed, contaminants such as residues of the potting liquid or foreign substances accumulate in the nozzle (100) from which the potting liquid is discharged. If these contaminants accumulated in the nozzle (100) are not removed, the quality of the potting liquid application pattern may deteriorate or the nozzle may become clogged. Therefore, periodic cleaning of the nozzle (100) is required. Here, the contact-type nozzle cleaning device (10) according to the prior art performs nozzle cleaning by removing contaminants by contacting a contact member (sponge, etc.) to the nozzle. FIG. 3 is a schematic front view of a contact-type nozzle cleaning device according to the prior art. A contact nozzle cleaning device (10) according to the prior art includes contact members (110a, 110b) and a moving part (120). The contact members (110a, 110b) contact the nozzle (100) to remove contaminants attached to the nozzle (100). The moving member (120) moves the contact members (110a, 110b) that are in contact with the nozzle (100) to apply physical force to the nozzle (100). By means of the moving member (120), the contact members (110a, 110b) can apply physical force to the nozzle (100) to remove contaminants attached to the nozzle (100). However, the contact nozzle cleaning device (10) according to the prior art had a problem in that the maintenance time of the device increased because it required periodic removal of contaminants remaining on the contact members (110a, 110b), and deformation of the nozzle (100) was induced by repeatedly receiving physical force from the contact members (110a, 110b). FIG. 1 is a schematic front view of a nozzle for discharging potting fluid. FIG. 2 is a schematic diagram of a potting device for explaining a non-contact nozzle device according to the present invention.
