Barcode Label Technology Application

Protex Smart Technologies Co.,Ltd | Updated: Jul 04, 2017

For the metal bar code label design to provide reference for the realization of industrial, military and other harsh environments, Barcode Label the long-term preservation of goods and automatic extraction.

The non-destructive testing of the exchange field measurement technology used in metal bar code label detection and recognition, Barcode Label thus overcoming the metal bar code label anti-fouling ability of the shortcomings of poor.

The non - destructive testing method is applied to the detection and identification of metal tags. Based on the boundary equation and the two-dimensional Fourier transform of the magnetic standard potential in the film field theory, the analytical solution of the magnetic potential in the space above the metal tag is given under the condition of the high-frequency coil excitation. Barcode Label The intensity distribution of the magnetic field. Based on the simulation of the magnetic field strength, the influence of the metal substrate base material, the scoring and the excitation coil attribute on the identification of the metal tag is qualitatively analyzed, which can provide reference for the design of the metal tag.

(1) ACFM should select the amplitude detection method when accurately positioning the notch; (2) The metal label base material should be selected. (2) The metal label base material, Barcode Label the score and the excitation coil property and other factors on the identification of metal label identification ability (3) the location of the scoring should be as close as possible to the center of the excitation coil; (4) the depth of the score selection 4-8 mm is appropriate; (5) compared to the circular excitation coil, (6) Compared to the large size excitation coil, the small size excitation coil can improve the resolution ability of the notch; (7) Compared with the small size excitation coil, the large size excitation The coil can expand the distinguishable range; (8) by increasing the excitation frequency, can improve the ACFM detection process of anti-noise interference.

Bar code only printed on the carrier to form a bar code label to use value, but how do you know a bar code label is to meet your requirements? Of course, Barcode Label printing quality is important. Barcode Label You need bar code labels with sufficient precision, reflectivity and contrast to make them have a satisfactory first read rate. However, the quality of printing alone is not enough to protect your bar code application to be successful, if your bar code label can not survive in the corresponding environment, Barcode Label or can not firmly stick to the surface of the object, or can not let bar code scanning gun read many times, Or life cycle is not long enough, or can not meet the UL, CSA and the relevant provisions of the government, Barcode Label then the bar code label has no use value, your bar code application system will fall short. Therefore, when you invest in a bar code printing system, Barcode Label you must first test the system produced by the bar code label can meet your requirements.

Adhesive material consists of three parts: (1) surface material (2) plastic (3) at the end of paper. In the choice of labels, we should pay attention to the following questions:

1. The permanent and removable nature of the adhesive

To the performance of adhesive performance, Barcode Label the overall can be divided into two categories: permanent adhesive and removable adhesive.

2. Emphasize the meaning of the label surface

Labels processed with adhesive materials may be labeled on the surface of various materials such as glass, metal, cardboard, and plastic. The plastic can be further divided into: polyvinyl chloride, Barcode Label high-density polyethylene. Tests show that different labels have the greatest impact on label performance.
