Embodiment Construction

[0036] This part lists the specific implementation of the method for improving the reading rate of the data matrix code on the tool. The object to be processed is a silver-gray 10mm drill bit: the marking content is ABCD1234.

[0037] The first step is to select the surface on which the barcode will be marked.

[0038] Since there is a central positioning hole on the end plane of the tool and the area is too small to mark the barcode, it is necessary to mark the outer cylinder of the tool. At this time, a rectangular data matrix code should be selected, and the length of the code is along the axis. Orientation, the width dimension should not exceed 16% of the diameter of the cylinder, see Figure 1.

[0039] The second step is the roughness treatment of the marking surface.

[0040] The surface roughness Ra of the outer cylindrical surface of the tool is 0.8 μm, and the value is between 0.2 μm and 6.3 μm, which can be read normally. In order to ensure a high success rate of...

Abstract

The invention is concerned with an enhancing method for recognizing and reading ratio about the data matrix code signed on knife. It solves the problem that the application of directly signing data matrix code technology on knife and depends the pretending dispose method of sign face to solve the wear and tear, pollution and rusty problem of the signed code on knife. It also solves the problem that the contrast of code is small and the quality of figure is bad induced by the glisten of metal surface by enhancing the contrast of mark and the coarseness degree of mark surface. If the code is distortion and is difficult to recognize for the surface shape of knife, it improves by the selecting method by marking surface, and it enhances the recognizing and reading ratio about the data matrix code signed on knife greatly.

Description

technical field [0001] The invention belongs to the technical field of automatic identification of manufacturing resources such as knives. Background technique [0002] At present, the automatic marking management of tool resources mainly adopts one-dimensional barcode technology, radio frequency identification RFID technology and direct marking data matrix code technology. One-dimensional barcode technology is to attach barcode labels reflecting tool information to corresponding tools. This method is low in cost and is widely used in the management of tool warehouses. However, the problems of this method are also prominent, such as: the barcode label is separated from the tool, and the error reading caused by manual intervention is unavoidable; small tools cannot be pasted with barcode labels; the tool database must be used in the background to obtain all its information. Radio Frequency Identification (RFID) technology reads and writes the coded data contained in the ele...
