Description

Stationary laser scanning equipment

technical field

The invention relates to a scanning device, in particular to a fixed laser scanning device.

Background technique

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.

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 scanned, it will directly affect the work and lead to stagnation, resulting in losses; moreover, the engine part and the grip part of the laser scanner are generally designed into an integrated structure, such a structure cannot be disassembled in time for maintenance when the laser head fails, which is inconvenient for maintenance, and the integrated There is also a situation in which the laser head is damaged in the structural design, and the grip part can no longer be used, resulting in waste; there is also a laser scanner in the prior art that needs to be manually scanned one by one. When the operation is stopped in the middle, people will Put down the scanner directly, which will cause damage to the engine of the scanner after a long time, and people need to hold the scanner with their hands to scan when scanning codes, which will also cause certain damage to people's wrists after a long time. The oppression causes damage to the wrist.
