In visual inspection equipment, it is very important to ensure the sealing between lens accessories and lens to prevent dust from entering, which is related to image quality and the service life of the equipment.
First of all, from the design point of view, a special sealing structure can be used at the connection between lens accessories and lens. For example, the material of the rubber sealing ring should have good elasticity and durability. When the lens accessories are installed on the lens, the sealing ring is squeezed and deformed, which can tightly fill the gap between the two and effectively block the entry of dust. At the same time, the shape and size of the sealing ring should accurately match the connection part to ensure a full range of sealing effects.
Secondly, the installation process is also the key. When installing lens accessories, ensure that the operation is standardized and the force is moderate. If the installation is too loose, a good sealing effect cannot be achieved; and if the installation is too tight, the accessories or lens may be damaged. Professional installation tools can be used to install in the correct installation order and angle to ensure that the lens accessories fit tightly with the lens and will not cause damage to it.
Furthermore, for some situations where lens accessories need to be replaced frequently, a quick-connect interface with good sealing can be designed. For example, a bayonet connection is used, and a sealing pad is set at the bayonet. When the accessory is inserted into the lens, the pad can automatically fit to form a seal. At the same time, the interface should be cleaned and inspected regularly to remove impurities that may affect the seal.
In addition, a special dust-proof coating can be used on the surface of the lens and accessories. This coating can not only reduce the adhesion of dust, but also generate a repulsive force when a small amount of dust approaches, further preventing dust from entering the gap between the lens and the accessories. In the environment where visual inspection equipment is used, certain dust-proof measures can also be taken, such as installing air filters, etc., to reduce the dust content in the air and reduce the possibility of dust entering between the lens accessories and the lens. Through the comprehensive application of the above methods, the sealing between the Vision Inspection Equipment Lens Accessories and the lens can be effectively ensured, providing a guarantee for high-quality visual inspection.
