[0001] The utility model relates to the field of optical inspection machines, in particular to a lens cleaning device for optical inspection machines. Background Art

[0002] An optical inspection machine is a device that uses optical principles to detect and measure. It can be used to detect and measure the size, shape, surface quality and other characteristics of an object. An optical inspection machine usually includes components such as a light source, a lens system, a sensor, and an image processing system. It uses optical imaging and digital image processing methods to detect and measure objects.

[0003] The optical inspection machine detects the features of an object through an optical lens, but dust easily accumulates on the optical lens during long-term use, so it is necessary to scrape off the dust with the help of a lens cleaning device for an optical inspection machine. For example, the prior art Chinese patent announcement number "CN213904031 U" discloses a sealed and anti-fouling optical imaging lens, including a fixed bracket, a lens assembly mounted on the fixed bracket, a cleaning assembly and a sealing assembly mounted on the fixed bracket and respectively located on both sides of the lens assembly, and a driving assembly driven and connected to the cleaning assembly and the sealing assembly; the cleaning assembly includes a cleaning rotating shaft that is convertibly mounted on the fixed bracket, a first driven wheel mounted on the cleaning rotating shaft, and a cleaning brush mounted on the cleaning rotating shaft, and the sealing assembly includes a sealing rotating shaft, a second driven wheel mounted on the sealing rotating shaft, and a sealing cover mounted on; when the utility model needs to be used, the lens is first cleaned in an alternating manner, and then the sealing assembly and the cleaning assembly are driven to the horizontal direction by the driving assembly, which will not block the lens detection, can effectively clean and prevent dirt, and has a practical and reliable structure.

[0004] Some optical imaging lenses use a driving motor to drive a pair of rubber rings to clean the lens. However, in actual operation, considering that similar cleaning measures need to be cleaned by a pair of rubber rings, the rubber rings and the sealing cover cannot be disassembled. In this way, the rubber rings will accumulate dust and wear after long-term use, which is not only inconvenient to replace, but also increases the cost of replacing the rubber rings, affecting the normal use of the optical lens and having poor practicality. Utility Model Content

[0005] The utility model aims to solve the above-mentioned shortcomings of the prior art that the rubber ring is inconvenient to replace and the replacement cost is high, and proposes a lens cleaning device for an optical inspection machine.
