Description

Technical Field

[0001] The utility model relates to the technical field of bar code printing, in particular to a label positioning device for a bar code printer. Background Technique

[0002] A bar code label printer is a printer specifically used for printing bar codes, two-dimensional codes and other labels. It usually adopts thermal transfer or thermal printing technology. The print head heats the coating on the ribbon or thermal paper to form corresponding graphics and characters, and then prints them on the material to be printed. By printing bar codes or two-dimensional codes, fast and accurate item identification and information entry can be realized.

[0003] When optimizing the existing label positioning device for bar code printers, most of them are reflected in the convenience of changing label information. Only the printer needs to be controlled, and there is no need to replace the label tape. For example, the Chinese utility model patent with the application number CN201811017939.3 discloses "a wafer labeling device for integrated circuits". In this device, it includes a cartridge mounting plate, a take-up cartridge, a feed cartridge, a first motor, a guide rod, an inkjet printer, a guide rod positioning assembly, an inkjet printer fixing seat, a discharge chute and a feed detector. Its advantage is that it is convenient to change label information, and only the printer needs to be controlled, and there is no need to replace the label tape.

[0004] Although the above-mentioned label positioning device for bar code printers has certain advantages in terms of conveniently changing label information, it still has certain drawbacks: when the print head heats the coating on the ribbon or thermal paper to form corresponding graphics and characters and then prints them on the material to be printed, the material to be printed is prone to warping due to the force, or when different specifications of the material to be printed are printed and displaced on the conveying table without external force suppression, it is prone to position deviation, resulting in non-standard printing.
