  The basic function of the lens is to achieve beam transformation (modulation). In machine vision systems, the main function of the lens is to image the target on the photosensitive surface of the image sensor. The quality of the lens directly affects the overall performance of the machine vision system, and the proper selection and installation of the lens is an important part of the design of the machine vision system. Below, TEO will take you to understand the cleaning and maintenance methods of the industrial camera lens body.

  Industrial camera lens body cleaning and maintenance methods:

  1. When using and carrying industrial cameras, be very careful not to drop or smash industrial cameras to avoid strong vibration, shock or squeezing. When carrying an industrial camera on a motorcycle, car, boat, airplane, etc., it should be protected with a thick mat. When using a tripod, be sure to stand steady, especially to prevent the tripod from being kicked or swept by the wind.

  2. Do not try to open the lens cover of the fully automatic industrial camera by hand. The lens cover will automatically open only when the switch is on, and the lens cover will automatically close when the switch is closed.

  3. Fully automatic industrial cameras should use film with DX code to purchase film, to ensure that the DX code mark is on the cassette. If a film without DX code is loaded, the sensitivity will be automatically set to a certain value, regardless of the actual sensitivity of the film, which may cause the exposure to be incorrect.

  4. Avoid placing industrial cameras in closets with hygienic balls or in laboratories that can seriously damage chemicals in industrial cameras. Store in a cool, dry, well-ventilated place. Never use industrial cameras such as paint thinner, alcohol or benzene.

  5. If the industrial camera is taken from a low temperature outdoor to a warm room, the moisture will condense into water droplets inside and outside the industrial camera. When bringing an industrial camera into a warm room, the industrial camera should be placed in a box or plastic bag to gradually change the temperature of the industrial camera. After the temperature difference is reduced, open the bag again.

  6. When replacing the battery, all old batteries should be replaced at the same time. Do not mix batteries of different brands, different types and different trademarks, or mix old and new batteries. Do not damage the battery, or charge the battery, and do not put the battery on the fire, as this will cause the battery to leak, self-heat, explosion, and so on. The battery should be installed in accordance with the indicated positive and negative poles.

  7. If the industrial camera has a date display mode, do not remove the battery until the battery is dead, as the date function requires battery power to keep it continuous.

  8. Infiltration of dirt, dirt, dust, moisture, harmful gases or salt water into industrial cameras can damage industrial cameras and prevent them from operating. To prevent industrial cameras from coming into contact with salty, humid air on the waterfront, prevent industrial cameras from splashing any liquid or rain. When industrial cameras are exposed to rain or contact with moisture, the water should be wiped off and allowed to dry.

  9. The temperature range for general industrial cameras to work normally is 40 to -10 ° C. Care should be taken to avoid industrial cameras being placed in high temperature and high humidity environments for a long time, such as in summer cars.

  10. Never try to disassemble an industrial camera.

  Since the quality of the lens has a great influence on the quality of the image, it is also one of the most delicate parts. So its use and protection is even more important.

  First, keep the lens clean. When you hang the industrial camera around your neck, the lens must be attached with a lens cover or a transparent UV mirror to protect the lens from dirt, oil or other debris, and not accidentally leave fingerprints on the lens. on. Don't stack the lens with other items without touching it. Don't touch the lens with your hands, or let the harder objects touch the lens, and don't get into the habit of letting go. Because the lens is dirty, the image quality will be degraded. For example, an image taken with a dusty lens will appear to be low-contrast and blurred. If there is a fingerprint on the lens, it will be faithfully reflected on the printed photo. In your camera bag, you should have a lens brush, air blower (also called ear wash), lens paper, etc. If you find that the lens is dirty, use a special lens brush to remove dry matter such as dust, and oil, Fingerprints need to be wiped with a special cleaning agent and a special soft cloth. Don't use hard things to scrape, so that not only can the lens not be cleaned, but it will cause more damage and slashing to the lens. The lighter will be sent to repair, and the heavy one will be scrapped.

  The above is the introduction of the cleaning and maintenance method of the industrial camera lens body from TEO Xiaobian. The lens is generally made of glass. The axis of the lens in each lens group, the position between the lens and the lens are carefully Design and arrangement, during use, care should be taken to prevent the lens from being subjected to strong vibrations and bumps, so as to avoid cracking or shifting of the lens glass, thereby affecting the image quality. When you put an industrial camera on a tripod, this problem is very easy to happen, so be careful.
