First, the whole machine clean coating machine and maintenance

1. Check the calibration platform and the external surface of the machine is glue, timely cleaning.

2. Check the machine drive mechanism screws are fastened, including X, Y, Z, track transfer, AM mechanism.

3. Regular cleaning polish of screws and rails for x, Y, z amplitude modulation.

4. Check whether the cooling fan is working properly, whether the circuit has broken off and loose terminals.


Second, Rubber valve cleaning

When using the point glue machine, the rubber valve should be cleaned after the application of the coating machine or the replacement of rubber types. Otherwise, it is easy to cause the dry glue in the cavity to be difficult to clean. The nozzle is blocked and the impact needle solidifies in the cavity.

1. How to maintain

First close the injection valve to remove the plastic bucket and over plastic barrels to open the injection valve, the guide lines and cavity remaining after discharge to close the injection, rubber in empty plastic barrels pour a little alcohol to open the valve and discharge clean alcohol, nozzle, cavity, guide hose will be removed and into the beaker with alcohol or acetone to use ultrasonic oscillations for five minutes, with hair scrub clean out after using tools - > coating machines reinstall injection valve.

2. How to maintain hot-melt adhesive piezoelectric valve

Keep plastic barrels of heating and heating block heating to close the valve to remove the residual glue, fitted with high temperature resistant empty plastic bucket to pour into solid paraffin and liquid paraffin, for about 2 min in paraffin wax melting to open the valve, the diversion channel and residual rubber seat, stay out only paraffin to close the valve, nozzle, the nozzle lock set, flow guide removed - into a beaker with alcohol or acetone to use ultrasonic oscillations for five minutes, with hair scrub clean out after using tools to reinstall the piezoelectric valve.
