## Abstract

A device for identifying an aluminum alloy die-cast hub includes a laser scanning means, a controller and a computer, in which the laser scanning means includes an image sensor and is configured to shoot an image from the surface of the aluminum alloy die-cast hub; the controller and the computer are in data connection with the image sensor, and the model information of the hub is read from bar code information.

## Claims

### Claim 1

A device for identifying an aluminum alloy die-cast hub, comprising a laser scanning means, a controller and a computer, wherein the laser scanning means comprises a laser head with a first objective lens and an image sensor with a second objective lens and is configured to shoot an image from a surface of the aluminum alloy die-cast hub; the controller and the computer are in data connection with the image sensor, and model information of the aluminum alloy die-cast hub is read from bar code information, wherein the first objective lens and the second objective lens are configured such that an optical path of a laser emitted by the laser head of the laser scanning means passes through the first objective lens, is incident on a bar code on the surface of the aluminum alloy die-cast hub to be detected after passing through the first objective lens, and passes through the second objective lens after being incident on the bar code to reach the image sensor, and the first objective lens and the second objective lens are rotatable objective lenses.

### Claim 2 (depends on 1)

The device for identifying an aluminum alloy die-cast hub according to claim 1, wherein the laser scanning means is configured to read a change in height, width or color of the bar code on the surface of the aluminum alloy die-cast hub.
