How does the automatic glue dispenser carry out liquid injection to the dripping point and the specific operation method?

Injection and drop point of liquid material

1. Note to

1) Low-viscosity liquid materials can be poured directly into the syringe. Specific steps: 

a) Put the needle nozzle cover on the needle nozzle;

b) Place the syringe on the syringe rack;

c) Pour the liquid material into the syringe, not exceeding 3/4 of the volume of the syringe, with the help of a funnel tool.

2) Medium and high viscosity liquid materials

Simplify work with the additional double feeder. Specific steps:

a) Fix the storage tank filled with liquid material on the shelf;

b) connecting the syringe and the magazine fixed adapter;

c) Connect the high-pressure air source of the storage tank;

d) Adjust the air pressure of the high-pressure air source to add the liquid material from the storage tank to the syringe, not exceeding 3/4 of the volume of the syringe.

2. Drop point

Drop point volume adjustment steps:

1) Set the device to any spit mode except "F1";

2) Adjust the spit out time dial and interval time dial to the appropriate position;

3) Press "SHOT" to test the dropping point.

Dispensing operation process

Dispensing can be carried out according to the following steps:

1) Syringe installation: select a suitable needle nozzle and install it on the syringe;

2) Liquid material injection: refer to Figure 8 and the corresponding liquid material injection instructions;

3) Debugging

  a) Spit out mode: set the spit out mode encoder to F1;

  b ) Power connection: turn on the power switch to turn on the host;

  c ) Air pressure adjustment: adjust the air pressure regulator so that the air pressure is 25psi as the initial calibration test;

  d ) Press "SHOT" until the liquid material is evenly spit out and the machine works normally;

  e ) Drop volume adjustment: adjust the spit-out time dial key, air pressure regulator and needle nozzle thickness to obtain a suitable liquid material spout volume, except for the F1 spout mode;

  f ) Vacuum retraction force: adjust the vacuum controller so that no liquid drops will seep out when the liquid material is spit out;

  g ) Automatic timing: If automatic timing control is required, it can be realized , except for the F1 spit out mode;

4) Epoxy

Precautions and Maintenance

1. Routine maintenance

●Clean the needle cylinder in time after the work is over, so as to prevent the material from solidifying and difficult to clean. The cleaning steps are as follows:

a) Soak in organic water for 5-10 minutes;

b) Remove residual material from parts.

●When using, the material at the needle nozzle should be removed in time to prevent the material from solidifying and blocking the needle nozzle.

2. Precautions for use

● The working air pressure of the equipment shall not exceed 5.5 bar, so as to ensure the normal use of all parts;

The liquid material needs to be stirred evenly before work, so as to ensure that the drop point is consistent in size;

● Placing the syringe reasonably, do not let the liquid material flow into the air pipe and cause damage to the parts;

● The vacuum controller cannot be adjusted too large, so as to avoid damage to parts caused by liquid material being sucked into the air pipe;

● Properly dispose of discarded syringes and needle nozzles to prevent environmental pollution.
