Laser scanner with detachable front end

Abstract

The invention discloses a laser scanner with a detachable front end. The laser scanner comprises an engine part and a holding part, wherein the engine part is fixed to the upper end of the holding part; a circuit board, a photo-sensor and a control circuit are arranged in the holding part; the engine part consists of an engine head and a positioning seat; the engine head is detachably arranged in the positioning seat; the engine head further comprises a laser scanning window that is recessed inwards; a dust removal mechanism used for removing dust on the laser scanning window is arranged at the upper end of a scanning head of the laser scanning window; and a longitudinal sliding mechanism for driving the dust removal mechanism to run is arranged on the side surface of the front end of the laser scanning window. The laser scanner has the beneficial effects that the laser scanner not only can realize detachable connection between the engine head and the holding part and is convenient to overhaul but also can realize automatic dust removal all the time, and a dust removal mode is simple, convenient and flexible; the service life of the laser scanner can be prolonged, the fault rate of the laser scanner is greatly reduced, the working efficiency is improved, and the loss is reduced; and the laser scanner is high in feasibility.

Description

technical field [0001] The invention relates to a scanner, in particular to a front-end detachable laser scanner. Background technique [0002] The laser scanner is used to record the price, name, item number and other information of the commodity, and scan the barcode optically, which can quickly read the data, reduce a lot of time that originally required manual data entry, and save management and personnel costs. At present, the scanners for reading and barcodes can be divided into two types: fixed and handheld according to the operation mode. Among them, the handheld barcode scanner is a relatively economical and convenient device for reading barcodes. When the scanner reads the barcode, the positional relationship and angle between the scanning head and the barcode label are closely related to whether the barcode data can be read correctly and quickly. [0003] The scanning head of the laser scanner in the prior art is designed with a concave structure, and more dust w...

AI Technical Summary

Problems solved by technology

[0003] The scanning head of the laser scanner in the prior art is designed with a concave structure, and more dust will adhere to it during continuous use, so that the laser scanning head will not be able to scan effectively during the scanning process. As a result, laser scanners will be limited after a period of use, and in supermarkets and other large manufacturers or places where laser scanners are used, once the scanning fails or the barcode cannot be sc
