Advantages of UVLED exposure machine compared with traditional exposure machine
1. Single band, high photoelectric conversion rate, uniform irradiation energy:
The traditional exposure machine (mercury lamp) is scattered light, which is composed of bulbs, electrodes and discharge gas. The wavelength of the emitted light source is between 350-450nm, the spectrum is long, the UV utilization rate is low, and the energy uniformity is only 70-80%; The UVLED exposure machine is a parallel light source, which emits 365nm/395nm single-band light source, has no clutter energy consumption, and the energy uniformity can reach 90%, which is suitable for the precision circuit industry.
2. High efficiency and energy saving:
The mercury lamp needs to be turned on in advance to preheat the device when it is in use, and it needs to be turned on all the time during work, which consumes a lot of power; UVLED uses UV diode chips to emit light, which can be instantly lit and the output energy can be set by itself, which is very energy-saving and easy to operate.
three. No harmful emissions, safe and environmentally friendly:
The traditional exposure machine (mercury lamp) emits a spectrum with a wavelength below 200nm, which will change oxygen O2 in the air to produce ozone O3 (the mercury lamp workshop will have a small smell), and the mercury lamp itself will also bring mercury pollution. There is no effective way to deal with mercury pollution; while the UVLED exposure machine is a light-emitting UV diode chip, which is the conversion of electrical energy into light energy. It is a clean and environmentally friendly curing method that produces pollution.
Four, long service life, no consumables:
The service life of the mercury lamp is 300-600h, and the mercury lamp bulb needs to be replaced regularly; the UVLED exposure lamp can be used for more than 20,000 hours, and the UVLED curing light source can be used for several years.

6. Maintenance and precautions

1. When exposing, the glass surface must be kept clean, no scratches. Rubber blanket cannot be with the thinner, battery water and other Solvent contact.

2. Before the exposing, if the grease or tape and other stolen goods stick to the glass, can be wiped with water and alcohol to avoid the shadow affect the exposure quality.

3. In the use of UV exposure lights, should pay special attention to: each exposure is completed, should wait 15 to 50 minutes, to be purple outside the light a little cooling down in order to carry out the second exposing. Otherwise, the UV light will not start, and shortened life of UV lamps.

4. Covering the screen with the middle hardness of rubber blanket, can extend the life of rubber blankets.

5. Half a year should check the circuit, vacuum pump once, and make the grounding resistance less than 4 ohms.

6. Lamp issued by the strong ultraviolet spectrum, the operator in the normal work, should not be directly in contact with the light, ensured safety and health of the operator.

7. When the lamp is triggered, the trigger voltage is high and should be well grounded to ensure safe operation.

8. Replace the lamp

Cautions:

Be sure to turn off the unit before replacing the lamp. When the lamp is used for a long time, the light effect is too low or the trigger is not lit, the new lamp should be replaced. Method is to remove the lamp from the column, hand from the light box into the lamp cover below, so flip down, loosen the fixed screw, the lamp carefully removed from the marble, and then the new lamp from the new fixed You can, the stain on the tube, cotton can be dipped in a little alcohol gently scrub clean.

7. Instructions

1. First of all, the power line drawn from the exposure machine connected to the three-phase four-wire 380V power supply, and the power (line voltage) wave cannot exceed 380V +10 V, the best of the body to a good grounding, and the grounding resistance is less than 4 ohms.

2. Wipe glass clean with water or alcohol, so as not to have the impact of product exposure quality.

3. Turn on the power; turn on the lamp under the glass, and operating the fan.

4. Place the patterned film face up in the middle of the glass, fix it with a clear tape, and apply the soaked and dried the screen on the good position, positive pressure on the film.

5. Place the end of the suction pipe fixed on the edge of the suction port in the center of the screen. The role is to screen the central air pumping, forming a vacuum, so that the screen can be evenly pressed film film, so as to clear lines out, pattern beautiful online version.

6. Close the cover

7. Exposure time generally takes more than ten or several tens of seconds. Line fine, tone level rich film, exposure time correspondingly shortened; the opposite line rough, large pattern area, exposure time corresponding to extend some. In addition, different exposure requirements, different film, different photosensitive pulp and if exposure machine suing too long, exposure time are not the same should be based on practical experience to choose.

8. After the exposure time is determined, press the "Suction Start" button to make the vacuum pump work, until the vacuum pump to completely remove the air inside the frame, check the screen has been pressed on the film, can press the "exposure start" Button, so that the UV exposure light. When the "exposure start indicator" is on, after the delay, you can press the "exposure start" button. At this time, the exposure time setting relay starts the standby work when the "exposure start" button is pressed, and the time to reach the exposure time, the exposure end, the vacuum pump and the exposure are automatically stopped.

9. Open the cover; remove the screen for rinsing, exposure process complete.

8. Fault repair

1. Turn on the power switch and the fan does not work

  1. Check if the floor fuses are loose or blown.

  2. Check whether the fan capacitor burns, fan blades are deformed, the fan is bad.

  3. Whether the plug is loose or welding is not strong.

  2. Put down the screen frame, the vacuum pump does not work

   1. Check if the wiring of the vacuum pump is off.

2. Check that the vacuum pump base switch is open.

3. Check that the delay on the panel timer is faulty or the backplane contactor is not working.

3. Vacuum pump work, vacuum cannot reach standard

   1. 1. Check that the suction pipe on the vacuum pump is plugged in.

2. Check if the oil level of the vacuum pump is too low

3. Check the battery valve is working properly (vacuum pump open, solenoid valve closed, suction; vacuum pump, electromagnetic the valve opens and deflates.)

4. Check the rubber on the side of the tape if there are cracks, shedding and so on.

5. When printing large plate, should extend the inspiratory time.

4. Press the trigger switch, the lamp does not light

1. Check if the supply voltage is too low.

2. Check whether the ends of the lamp are black and the lamp is aged.

3. After the use of UV light, the fan cooling lamp is up to 1 to 2 minutes (due to continuous UV lamp using the cooling time is short, the lamp does not light up.)

4. Check whether the trigger is aging, with or without high pressure.

5. Check whether the 60A solvent is blown.

6. Check whether the two thick wires of the connector are off

5. Lamp light, vacuum pump work, but the PS version cannot work properly.

  1. Check the lamp is full power work (current is generally between 8 ~ 12A normal)

2. Check the vacuum pump trachea can reach 0.08Mpa below, if not reached should be checked according to Article 3 above.

3. Check that the lamp is in its lifetime or no UV spectrum.

4. Check whether the exposure time is accurate, the quality of the media, the concentration of the developer is met.

6. Leakage

First check whether there is obvious ground o phenomenon, the fan is leakage, the capacitor is breakdown, and then check the light box flip lamp cover (that is, light cover), when Turn on or off whether it touches the leads at both ends of the lamp.

7. Please refer to the electrical schematics for each unit code.

8. Exposure Machine should be installed in a well ventilated place to keep the machine clean and operated by special personnel.
