Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of spectacle lens packaging, and particularly relates to a high-dispersion lens anti-slip conveying device for a packaging machine. BACKGROUND

[0002] In the packaging process of optical lenses, high-dispersion lenses are prone to slipping, displacement, and even damage, especially when being conveyed by a conveying belt, at the joint position of two conveying belts, which affects production efficiency and product quality. The conventional conveying method mostly uses ordinary conveying belts, lacks effective anti-slip measures, and especially when the lenses need to be accurately positioned, transferred, and packaged, the prior art cannot guarantee stable transmission of the lenses. In addition, the lenses are prone to misalignment during the transition between the conveying belts, affecting the accuracy of subsequent processes. Therefore, it is of great significance to develop a conveying device that can effectively prevent high-dispersion lenses from slipping and accurately center during conveying, to improve production efficiency and reduce losses. SUMMARY

[0003] The utility model aims at solving the above prior art's insufficient, provide a kind of high-dispersion lens anti-slip conveying device for packaging machine.

[0004] A high-dispersion lens anti-slip conveying device for a packaging machine includes two horizontally arranged conveying belts. Each conveying belt has a driving roller and a driven roller at both ends. The driving roller is driven by a stepper motor. Two symmetrical chain grooves are provided on the driving roller and the driven roller. The driving roller and the driven roller are connected by two support chains. The outer layer of the support chain is attached with a flexible buffer material. A non-slip layer is provided on the surface of the flexible buffer material. The inlet of one conveying belt is connected to the outlet of the other conveying belt. A suction cup is provided above the joint position. The suction cup is connected to an air pump through a conduit. The suction cup is installed on a lifting device, which is connected to a translatable linear track. A centering device is provided below the outlet of the conveying belt on one side of the joint position. The centering device includes two symmetrical clamps. Each clamp has two vertical and symmetrical vertical columns. A telescopic device is provided between the two clamps. Each side of the telescopic device has a set of telescopic rods. The two sets of telescopic rods are synchronously telescoped and connected to one clamp respectively.

[0005] As a further improvement, the vertical column is coated with a cylindrical polytetrafluoroethylene material.

[0006] Advantages:

[0007] Anti-slip transport: The support chain with flexible cushioning material and anti-slip layer can effectively increase the stability of the lens during transport and reduce the risk of slippage.

[0008] Smooth transition: Two conveyor belts are docked together, and a suction cup is installed above the docking point. The suction cup can be used to attach the lens, so that it can be smoothly transitioned between the conveyor belts, avoiding misalignment and falling.

[0009] Precise alignment: An alignment device is installed at the conveyor belt exit, which achieves high-precision alignment through grippers and telescopic rods, ensuring that the lens is accurately positioned before entering subsequent processes and improving processing accuracy.

[0010] Reduced damage: The posts on the grippers are covered with polytetrafluoroethylene material, which reduces friction and scratches on the lens surface, protects lens quality, and improves yield.

[0011] Highly adjustable: The grippers of the centering device can extend and retract synchronously, making it suitable for high-astigmatism lenses of different specifications, thus improving the versatility and adaptability of the equipment. Attached Figure Description
