Description

Technical Field

[0001] The utility model belongs to the technical field of cutting, and in particular relates to a mobile phone camera lens cutting device. Background Art

[0002] Mobile phone cameras are transparent materials with one or more curved surfaces made of optical materials such as glass or resin. Mobile phone camera lenses have good scratch resistance and high refractive index. Mobile phone camera lenses need to go through processes such as cutting, grinding and polishing during processing. Cutting is an important step in the processing of mobile phone camera lenses.

[0003] Most existing mobile phone camera lens cutting devices use lasers for cutting. Laser cutting has high efficiency. During the laser cutting process, multi-axis control of the laser head and the carrier plate is required to move in order to cut the designed lens shape.

When the supporting plate 304 moves to the left, the moving plate 301 moves to the left. When the second servo motor 702 is started, the second servo motor 702 can drive the first rotating rod 703 to rotate counterclockwise, the first rotating rod 703 drives the first bevel gear 704 to rotate and drives the transmission rod 707 to rotate, the transmission rod 707 drives the second rotating rod 710 to rotate through the square rod 709, and the second rotating rod 710 drives the third bevel gear 711 to rotate counterclockwise, and the second bevel gear 705 can rotate clockwise through the meshing of the first bevel gear 704, and the second bevel gear 705 can drive the first round rod 706 The fourth bevel gear 712 rotates clockwise, and the third bevel gear 711 is meshed to make the fourth bevel gear 712 rotate counterclockwise, and the fourth bevel gear 712 rotates in the opposite direction to the second bevel gear 705, so that the fourth bevel gear 712 drives the second round rod 713 to rotate counterclockwise, so that the second round rod 713 rotates in the opposite direction to the first round rod 706.
