Description

Technical Field

[0001] The utility model relates to the technical field of laser scanning, and in particular to an integrated anti-fall laser module for code scanning. Background Art

[0002] A laser barcode reader is a device that uses laser technology to scan and identify barcodes. It usually scans the black and white stripes of a barcode or QR code by emitting a laser beam, and converts the scanned information into a digital signal to achieve fast and accurate recognition and collection of barcode information.

[0003] The existing laser barcode reader is a single-line scanner using a laser diode as a light source. It uses a laser spot to form a laser line after being reflected by a reciprocating prism. After scanning a one-dimensional barcode, a series of laser reflection spots are generated, which are then collected and focused by a lens and converted into electrical signals through a photodiode to further identify the one-dimensional barcode. Laser barcode readers are generally installed in a fixed position to identify the barcode of an object.

[0004] However, the laser barcode reader is fixed, and the scanning depth of field is too long, which makes it impossible for the laser barcode reader to get close to the object. It can only exert its high recognition effect when the reading distance exceeds 40mm, which cannot meet the requirements of close-range reading, and thus causes the instrument size to be too large, thus affecting the instrument cost.
