Description

Technical Field

[0001] The utility model relates to the technical field of two-dimensional code scanning devices, in particular to an adjustable two-dimensional code scanner. Background Art

[0002] In the manufacturing industry, especially in the surface mount production (SMT) process, accurate material tracking and loading are crucial. At present, due to the problem of different materials being mixed in boxes when customers receive materials, it is common for materials to be reworked due to incorrect REEL IDs. To solve this problem, we propose to use a QR code containing material number, DC, LOT and loading quantity information on the material label, and achieve accurate material tracking and loading by scanning the QR code. For this purpose, we propose an adjustable QR code scanner.

[0003] The existing Chinese utility model patent with reference announcement number: CN217767457U discloses a multi-angle scanning two-dimensional code scanner. The multi-angle scanning two-dimensional code scanner is configured to include a two-dimensional scanner body. The bottom surface of the two-dimensional scanner body is provided with an angle adjustment mechanism. The angle adjustment mechanism is configured to manually rotate a threaded knob located at the rear end of the mechanism housing. The threaded knob pushes and pulls a fixed block through a rotating block at the front end. The fixed block pushes and pulls a rack through a connecting plate. The rack slides back and forth on the fixed bar through the rack on the bottom surface, and drives the gear to rotate during the sliding process. After the gear rotates, it drives the tilt angle of the top two-dimensional scanner body to change by adjusting the support rod. In this way, the multi-angle tilt adjustment operation of the two-dimensional scanner body can be conveniently realized by rotating the threaded knob, and the adjusted tilt angle can be limited, thereby improving the convenience of the payer during use and the use efficiency of the two-dimensional scanner body.

[0004] During the use of the existing adjustable QR code scanner, if there is a QR code on the surface of the device and the device is not placed properly, there will be a blind spot in the line of sight when the QR code is scanned, resulting in the QR code of some devices not being fully displayed, which may easily cause the scanner to scan unsuccessfully. In addition, the light in front of the scanner is strong, which causes the QR code to reflect when scanning, requiring the device to scan multiple times, affecting the working speed of the device, which needs to be improved. Therefore, a technician in this field provides an adjustable QR code scanner to solve the problems raised in the above background technology. Utility Model Content
