Introduction to LED Dispenser

LED special equipment, specially used for phosphor dispensing in the production process of white light-emitting LEDs.

Today’s LED dispensing machines can be roughly divided into two categories: one is pneumatic and the other is metering.

Because the glue quantity of LED phosphor is required to be very precise, and the glue quantity of the air pressure type will change greatly with the difference of the air pressure, so the air pressure type glue dispenser cannot meet the needs of the LED industry at all, so it is not called On the LED dispenser.

At present, the LED industry in the market basically uses the metering method. The accuracy of its glue volume can reach 1/10,000, which can satisfy the dispensing of LED phosphor powder. This is called a real LED dispensing machine.

Features of LED dispenser

High repeatability of dispensing (one millionth control accuracy);

Imported servo system, good stability, high repeatability, 24-hour uninterrupted operation;

The digital visual recognition system provides high-speed reference graphic positioning;

Equipped with a high-precision quantitative glue supply device to ensure the accuracy of each glue output and no dripping;

Setting parameter memory function, convenient setting and easy operation;

Accurate position control is realized through high-precision 3-element automatic positioning;

The dispensing consistency is 95%, concentrated in 2 bins;

Suitable for high-speed dispensing of high- and low-viscosity liquids;

The disassembly, cleaning and maintenance of the dispensing head are simple and convenient;

It is the first choice for SMD patch, high-power and high-viscosity quantitative dispensing.

Factors Affecting the Accuracy of LED Dispensing Machine

1. The rubber hose is blocked, the glue gun is blocked, and the glue is dried inside.

2. The air pressure is unstable and getting smaller and smaller.

3. There is a problem with the solenoid valve, which affects the outlet.

4. The glue is viscous, which affects the glue output.

LED dispenser maintenance

The daily maintenance of the LED dispenser directly affects the service life of the LED dispenser. The daily work of dispensing machine maintenance has a great influence on the service life of the LED dispensing machine, including the smoothness of the normal use process. The following are the daily maintenance steps of the LED dispensing machine:

1. To replace the rubber type, the pipeline needs to be cleaned. At this time, first close the feed valve, open the discharge valve, and discharge the remaining rubber material in the rubber bucket, close the discharge valve, open the feed valve, pour the cleaning solvent into the rubber storage tank, activate the machine, and press the solvent out according to the usual operation method. out rinse.

2. If the air intake is abnormal and moisture is found, please remove the moisture in the pressure regulating filter or check whether there is any abnormality in the air pressure source. Before the glue is used in large quantities, please try it out in a small amount first, and master the skills of using the product to avoid mistakes. The vacuum system vacuumizes and defoams the glue to remove the air bubbles generated during the mixing process, or let it stand for 10-20 minutes before using it, so that the air bubbles generated during mixing can be removed in time, and the more glue mixed together.

3. Please wipe clean the machine part regularly to increase the service life. The more the amount of glue mixed together, the faster the reaction and the faster the curing speed, so the glue should be properly mixed according to the actual production situation, otherwise the glue will be wasted. Eliminate accidents and improve production efficiency. Nowadays, liquid control technology and LED dispensing equipment are widely used in various production fields in modern industry.

4. When the machine is not in use for a long time, the power supply should be unplugged. This will not only prolong the life of the machine but also save a lot of electricity bills. With the needs of ever-changing industrial development, liquid control technology and dispensing equipment are also constantly developing to ultra-high precision control and diversification and specialization.

Precautions: After each use, clean it well, wipe it where you can see it, wipe it with alcohol, it is best to put oil or butter on the parts that are often moved, and keep it lubricated. If it is not used for a long time, it must be glued Light, otherwise it will solidify in the LED dispenser, and it will cost money to clean.
