Description

Technical Field

[0001] The utility model relates to the technical field of static electricity elimination instruments, in particular to a static electricity elimination fan in a lens assembly machine. Background Art

[0002] Static electricity is a static or non-flowing charge. When charges gather on an object or surface, static electricity is formed. Static electricity can cause a series of problems. For example, when a lens assembly machine is assembling a lens, static electricity will attract dust and make it difficult to remove, affecting the subsequent assembly of the lens. Currently, before the lens is assembled, an anti-static fan is used to eliminate the static electricity accumulated on the sample. The discharge device inside the anti-static fan will release positive and negative charges. The airflow generated by the rotation of the blades will send the positive and negative charges to the surrounding areas of the object, neutralizing the static electricity on the object sample, thereby achieving the purpose of eliminating static electricity.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent Publication No.: CN220476209U discloses a static electricity removal fan, including a base, a shell located above the base, and a fan and a discharge device located inside the shell, the discharge device is located in front of the fan, the front side of the shell is provided with an air outlet, and the rear side of the shell is provided with an air inlet, the static electricity removal fan also includes an output guide, the output guide includes a connecting part and a guiding part, the connection between the connecting part and the guiding part is bent upward, the front end of the guiding part is inclined downward, the connecting part and the guiding part are both hollow structures, the size of the front end opening of the guide part is larger than the size of the air outlet, the connecting part is installed on the shell through the air outlet, the static electricity removal fan is rotatably connected to the two side plates of the base through the left and right sides of the first shell and the second shell, respectively, according to the position of the sample, the angle of the fan can be adjusted by adjusting the angle between the shell and the base, so as to ensure that the ions with positive and negative charges generated by the discharge device can be blown to the sample surface by the fan, thereby improving the efficiency of static electricity elimination.

[0005] However, the above patent still has problems that need to be improved during actual use. The most obvious one is that the angle of the fan can only be adjusted in a single direction, which is difficult to meet the actual use needs of the enterprise, greatly reduces the application scope of the fan, and affects the actual use effect of the fan.

[0006] To this end, we proposed a static elimination fan in a lens assembly machine to solve the above-mentioned drawbacks. Utility Model Content
