How to clean the industrial camera
Author:Administrator   Published in:2019-12-31 15:37

  Industrial camera is a very precise product. Compared with general camera, its cost is much more expensive. First of all, for the newly purchased machine, before the product is bought back for use, it is necessary to look at the product manual and have a thorough understanding of the product, so as to ensure small damage to the product.

  Secondly, dirty dust will appear when the industrial camera is used for a long time, which will affect the performance and service life of the camera. It is very easy to reduce the performance and service life of the product by maintaining the product and not using it excessively. Therefore, it is necessary to clean and maintain the camera regularly to prolong the service life of the camera.

  Improper cleaning will damage the polished surface and special cover on the base or lens, and the damage of glass or cover surface will reduce the performance in all applications. The following is about the daily cleaning and maintenance methods of industrial camera image sensor (CCD and CMOS). For such precision equipment, the daily maintenance work is also very important. Correct maintenance methods and appropriate cleaning procedures are necessary means to ensure the quality.

  1. Suction suction

  This method is to use the suction of the vacuum pump to remove the dust on the surface of the image sensor of the industrial camera. The working principle is the same as that of the vacuum cleaner used in our family. The advantage of this method is non-contact dust collection and no damage to image sensor. The disadvantage of this method is that it can only absorb dry floating dust, but it is not very effective for dust and oil stains with adhesion.

  2. Electrostatic adsorption

  Using soft bristles with static electricity to absorb dust on the surface of image sensor of industrial camera, this method has the same advantages and disadvantages as the suction suction method. When choosing which method to use, it mainly depends on which tool is convenient to use.

  3. Fiber cleaning method

  The soft microfiber material is used to clean the image sensor by dipping into the active cleaning solution. It is better to use pure alcohol with a concentration of more than 90%. Do not use isopropanol. Isopropanol can absorb water in the air. When cleaning, it is easy to leave liquid traces on the surface of image sensor of industrial camera.

  It is better not to use methanol, which is a highly toxic substance. The advantages of this method are no damage, convenient operation, targeted removal, and certain effect on oily dust. The disadvantage is that if this method is used improperly, it is easy to get cleaner and dirtier, which is counterproductive.

  4. Sticky dust method

  The dust on the surface of image sensor of industrial camera is removed by using rubber stick or adhesive paper with low viscosity. This method is easy to operate, but the effect is general. It is easy to leave more difficult to clean offset after cleaning, resulting in secondary pollution. Therefore, this method is not recommended.

  No matter what method is adopted, it is necessary to pay attention not to use metal tools for processing, because it is easy to damage the image sensor. Mastering the correct and reasonable daily cleaning and maintenance methods of industrial camera image sensor can prolong the service life of the camera, and also can maximize the functional advantages of the industrial camera.

  During the maintenance of industrial cameras, the following points should also be noted:

  1. Do not touch the lens surface with your fingers

  Camera lens is a very precise part. Its surface is coated with antireflection coating. If you touch the lens with your fingers, the lens surface will be covered with oil stains and fingerprints, which is harmful to the coating, thus affecting the use of industrial cameras.

  2. Selection of cleaning equipment

  The micro fiber can penetrate into the surface of the lens to remove impurities, which can achieve the purpose of thoroughly removing impurities. When scrubbing the camera, you can choose pure alcohol with a concentration of more than 90%, but do not use isopropanol, which is easy to leave liquid traces on the sensor surface.

  3. Do not place the lens on a hard surface

  Keep the lens on a soft surface, especially if the optical surface is raised, resting on a hard surface can cause scratches on the surface.

  4. When not using the camera, cover the lens cover and keep it.

  Therefore, the lens cover can protect the optical surface from damage if it is not used in industry. If there is dust on the body of image sensor of industrial camera, just wipe it with soft and dry cloth. There are relatively stubborn oily dust, which can be wiped with a small amount of detergent dipped in a cloth.

  If there is dust on the lens, try to use the dust collection equipment to clean it. For oily dust, choose the appropriate dust removal method according to the pollution situation. I believe that the industrial camera can be used for a longer time if it is used in the right way, cleaned on time and kept properly.

  The above is about how to clean the industrial camera. TEO's products cover industrial and medical machine vision systems and products, mainly including: full series of industrial cameras, special cameras for industrial image measurement, special crosshair cameras for laser cutting, special image collectors for micro imaging, ultra-high definition pathological micro imaging conference system。
