Description

Technical Field

[0001] The invention relates to an automatic material taking device for a beam shaping lens and a use method thereof, belonging to the technical field. Background Art

[0002] The beam shaping process requires various lenses. After removing the lenses from the magazine, they are placed in a designated optical path to achieve beam shaping, ultimately achieving satisfactory beam quality. During this process, the material removal method impacts the efficiency of the entire beam shaping process. Traditional methods involve manual tweezers or pneumatic grippers, which can result in unstable gripping, lens drops, and contamination. Furthermore, manual gripping with tweezers or pneumatic grippers is difficult to control, which can easily damage the lenses. Manually gripping lenses during batch beam shaping is labor-intensive, error-prone, and labor-intensive. This is especially true for smaller lenses, where manual gripping becomes more difficult, significantly impacting beam shaping efficiency.

[0003] Chinese patent document CN112047107A discloses an optical lens material removal suction nozzle mechanism, which includes an upper mounting plate and an air guide tube. The upper end of the air guide tube is provided with a connecting sleeve. The upper portion of the connecting sleeve passes through the upper mounting plate and is connected to the air guide tube. The upper portion of the connecting sleeve is connected to the air guide tube. A lower mounting plate is provided below the upper mounting plate. The lower mounting plate is provided with a through hole. The air guide tube passes through the through hole. The lower end of the air guide tube is provided with a suction nozzle. The suction nozzle is connected to the air guide tube. The lower portion of the air guide tube is provided with a pressure sleeve. The outer sleeve of the air guide tube is provided with a lower spring. The upper end of the lower spring is fixed to the bottom surface of the lower mounting plate, and the lower end of the lower spring is fixed to the upper end of the pressure sleeve. Although this mechanism uses a suction nozzle to suck the lens under negative pressure, it is driven by a conventional drive device and lacks precision control. For this reason, the present invention is proposed. Summary of the Invention
