Full-automatic bar code printing quality detector and detection method

Abstract

The invention discloses a full-automatic bar code printing quality detector and a detection method. The detector comprises a computer and a bar code detector host. The bar code detector host comprisesa workbench which can move transversely and a probe base which is located above the workbench and can move longitudinally. The workbench is connected with a first driving motor through a first transmission mechanism, the probe base is connected with a second driving motor through a second transmission mechanism, a laser tube and a photoelectric amplifier are fixedly arranged on the probe base, and the light beam emitted by the laser tube is reflected by the bar code placed on the workbench and then irradiates a photoelectric amplifier. The detector has the advantages that size measurement andN times of detection of the bar code can be automatically achieved, scanning path intervals are uniform and equal, the overall printing quality of the detected bar code can be detected and evaluatedmore comprehensively and accurately, human intervention is eliminated and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of barcode detection, in particular to a fully automatic barcode printing quality detector and a detection method. Background technique [0002] Barcode technology solves the problem of data input in the process of computer application with the characteristics of reliability, speed, economy and practicality. Barcode has become the "common language" in international trade and the "identity card" of international commodities. [0003] A barcode is a set of black and white bar-space graphics with different widths and widths. It uses the change in the size of the bars and spaces and the difference in the optical characteristics of the bars and spaces to carry information, and realizes automatic data collection and automatic identification of information together with a computer. Therefore, the geometric dimensions and optical characteristics of bars and spaces are important parameters to ensure the correct readi...

Problems solved by technology

[0007] Aiming at the above-mentioned technical problems in related technologies, the present invention proposes a fully automatic barcode printing quality detector, which completely overcomes the current domestic and foreign barcode detectors relying on manual movement. Barcode detectors or barcode symbols are used to complete N times of detection of barcode symbols, and defects such as uneven scanning path intervals, low detection efficiency, easy human intervention, and inability to comprehensively and accurately evaluate the overall printing quality of the tested barcode symbols can be automatically realized. N times of barcode detection, the scanning path interval is even and equal, more comprehensive and accurate detection and evaluation of the overall printing quality of the tested barcode, eliminating human intervention and improving detection efficiency
