The exposure machine is one of the very important equipment in the printing industry. Its function is to transfer images or text to the printing plate for printing. However, during long-term use of the exposure machine, various failures will inevitably occur. This article will introduce in detail the troubleshooting and repair methods of the exposure machine to help customers better understand the maintenance and upkeep of the exposure machine.

1. Basic principles of exposure machine

An exposure machine is a device that uses ultraviolet light to transfer images or text to a printing plate. The basic principle of the exposure machine is: place the image or text to be printed on a transparent film, then place the film on the glass of the exposure machine, and then transfer the image or text to the printing plate through an ultraviolet lamp. The main components of the exposure machine include: exposure lamp, reflector, glass, film, printing plate, etc.

2. Common faults and troubleshooting methods of exposure machines

1. Uneven exposure

Uneven exposure is one of the common faults of exposure machines. The manifestation of this failure is that the image or text on the printing plate is not clear enough, or is blurred. The reasons for uneven exposure may be aging of the exposure lamp, pollution of the reflective plate, uneven glass surface, etc. The solution is to replace the exposure lamp, clean the reflector, replace the glass, etc.

2. Exposure time is inaccurate

Inaccurate exposure time is one of the common failures of exposure machines. The manifestation of this failure is that the images or text on the printing plate are blurred or missing. The reason for inaccurate exposure time may be the aging of the exposure lamp, incorrect exposure time setting, etc. The solution is to replace the exposure lamp, reset the exposure time, etc.

3. The exposure lamp is damaged

Damage to the exposure lamp is one of the common failures of the exposure machine. The manifestation of this failure is underexposure or uneven exposure. Exposure lamp damage may be caused by long-term use, unstable voltage, etc. The solution is to replace the exposure lamp.

4. The exposure machine cannot be started.

The failure of the exposure machine to start is one of the common faults of the exposure machine. The symptom of this kind of failure is that the exposure machine cannot start, or stops immediately after starting. The reason why the exposure machine cannot be started may be due to power failure, controller failure, etc. The solution is to check the power supply, replace the controller, etc.

3. Exposure machine maintenance methods

1. Exposure lamp replacement

The exposure lamp is one of the most easily damaged parts of the exposure machine. The method to replace the exposure lamp is: first turn off the power of the exposure machine, then remove the exposure lamp, and then install the new exposure lamp into the exposure machine.

2. Reflector cleaning

The reflective plate is one of the very important components in the exposure machine. Its function is to reflect ultraviolet rays onto the glass. If the reflector is contaminated, it will cause uneven exposure. The method to clean the reflector is: first turn off the power of the exposure machine, and then clean the reflector with detergent.

3. Glass replacement

If the glass surface of the exposure machine is uneven or cracked, the glass needs to be replaced. The method to replace the glass is: first turn off the power of the exposure machine, then remove the original glass, and then install the new glass into the exposure machine.

4. Controller replacement

If the controller of the exposure machine fails, the controller needs to be replaced. The method to replace the controller is: first turn off the power of the exposure machine, then remove the original controller, and then install the new controller into the exposure machine.

4. Maintenance methods of exposure machine

1. Regular cleaning

The exposure machine needs to be cleaned regularly to ensure its normal operation. The cleaning method is: first turn off the power of the exposure machine, and then use detergent to clean the surface and interior of the exposure machine.

2. Replace parts regularly

Parts in the exposure machine need to be replaced regularly to ensure normal operation. Replacement parts include exposure lamps, reflectors, glass, etc.

3. Pay attention to the usage environment

The exposure machine needs to be used in a dry and ventilated environment to prevent the exposure machine from being affected by moisture or dust.

The exposure machine is one of the very important equipment in the printing industry. Its function is to transfer images or text to the printing plate for printing. During long-term use of the exposure machine, various malfunctions will inevitably occur. This article introduces in detail the common faults and troubleshooting methods of exposure machines, as well as the repair and maintenance methods of exposure machines. We hope to help TAMPRINTER customers better understand the maintenance and maintenance of exposure machines.

FAQ（Frequently Asked Questions）

Q1，The overall size of our screen frame is 1.5*2m, what is the price of the exposure machine?

A1:First ask the customer clearly about the actual work requirements. It is a responsible performance not to quote directly.

Different industries have different technical requirements, especially the electronics industry or the color overprinting industry. The common practice is to install two gallium lamps at the bottom of the funnel. The disadvantage is that the uv energy in the middle part is very strong, which leads to substandard after flushing. The common practice not only leaks light at the bottom, but also the distance between the locks at such a long distance is too far, and the gap in the middle is also light leaks,

the middle of the locks will affect the appearance，can accept?

Is it acceptable to raise the funnel and the machine to be higher?

Is the uniformity above 80% up to the standard?

In what industry to use？

Q2：  How to judge the level of exposure machine?

A2.1：Turn it on to see the appearance,
Is light leaking from the bottom?
Is light leaking around?
Long-term exposure to ultraviolet rays will harm human health.

A2.2：The same work is for the shape of the 1.5*2m screen frame. There are many special attention to the lamp design. Some use 2 lamp tube sub-cavity design, different shutter control, some use the same shutter control of 2 lamps, some use a high-energy lamp but add High irradiation distance. Some people use LED lights to arrange evenly, and others use LED lights to scan.
 

A2.3：Open the wall to see the internal structure. Does the lamp have a centrifugal fan for heat dissipation? The ultraviolet lamp will generate a lot of heat when it emits light. If it is not radiated in time, it will affect the life of the lamp.

A2.4：Look at the neatness and standardization of circuit wiring.
