Decoding scanning assembly and decoding method thereof

Abstract

The invention discloses a decoding scanning assembly and a decoding method thereof. The decoding scanning assembly comprises a camera lens body, a lens assembly, a sleeve and an actuating device, wherein an accommodating space is formed inside the camera lens body; the lens assembly is assembled inside the accommodating space and comprises a plurality of lenses which are arranged sequentially in an optical axis direction; the outer surface of the camera lens body is sleeved with the sleeve; the actuating device is matched with the sleeve and can be controlled to conduct reciprocating movement relative to the sleeve; and the actuating device can be selected to be in linkage with any one of the plurality of lenses. According to the decoding scanning assembly, any one of the lenses of the lens assembly is driven by a voice coil motor to move to realize focusing, so that the focusing purpose is achieved, meanwhile, only the single lens is driven, the size of the decoding scanning assembly is reduced, and the energy consumption of the voice coil motor is reduced.

Description

technical field [0001] The invention relates to the field of barcode identification, in particular to a focus-adjustable decoding and scanning component and a decoding method thereof. Background technique [0002] Barcode scanning components are more and more widely used in our daily life. They can not only be used in supermarkets, retail stores, and warehouses, but also can be scanned by mobile phones and other communication tools to obtain merchant information, coupons, and login websites. No matter it provides convenience to the management of large supermarkets and warehouses, it also facilitates and enriches our daily life. [0003] In view of the problem that it is difficult to focus and obtain barcode information in decoding and scanning components in daily life, at present, it is preferable to use a combination of lens group and voice coil motor to move in the direction of the optical axis to achieve focus adjustment. The advantage is that it can accurately focus and ...

Problems solved by technology

However, in this device, a voice coil motor needs to be used to drive the entire lens group to move, and a small voice coil motor cannot meet the driving requirements at all, so a voice coil motor with a larger load-bearing capacity is used, and the volume of the device will be correspondingly reduced. Increased size is not conducive to transplanting into small mobile devices, and the voice coil motor with a larger load increases energy consumption
