Problems solved by technology

Although it is very convenient to use, the cost of this kind of centralized packaging is expensive and the cost is too high
As for unpackaged dock scanning, since the laser light and the camera are supplied separately, the cost is relatively cheap, but due to the lack of an effective solution for detecting the coaxiality of the laser light and the camera, it is difficult to popularize and apply

Embodiment 1

[0035] Please refer to the attached figure 1 , is a schematic flow chart of a method for detecting the coaxiality of a code scanning device provided in Embodiment 1 of the present invention. The code scanning device coaxiality detection system includes a detection table for carrying and connecting the code scanning device and a projection board arranged in front of the detection table.

[0036] The method specifically includes the following steps:

[0037] S101. The detection station sends a generation instruction to the code scanning device, so that the code scanning device generates a standard deviation circle on the screen according to the generation instruction.

[0038] It should be noted that the deviation circle is a criterion to measure whether the coaxiality of the laser light and the camera meets the production requirements. The innermost circle of the deviation circle represents the eccentricity within 1°, and the outer circle represents the eccentricity of 2°, 3°,...

Embodiment 2

[0053] Please refer to figure 2 , the embodiment of the present invention provides a system for detecting the coaxiality of a code scanning device, the system includes a detection platform 1 and a projection board 2 arranged in front of the detection platform 1 and at a preset distance from the detection platform 1;

[0054] The detection platform 1 is provided with a bearing position; during detection, the code scanning device 3 is placed on the bearing position and connected to the detection platform 1;

[0055] The detection station 1 is used to perform the following operations:

[0056] Send the generation instruction to the code scanning device 3, so that the code scanning device 3 generates a standard deviation circle on the screen according to the generation instruction;

[0057] Send an opening instruction to the code scanning device 3, so that the code scanning device 3 turns on the laser light and the camera according to the opening instruction;

[0058] Send the co...

Abstract

The invention discloses a coaxiality detection method and system for code scanning equipment, and the method comprises the steps that a detection platform transmits a generation instruction to the code scanning equipment, so as to enable the code scanning equipment to generate a standard deviation ring on a screen according to the generation instruction; the detection platform sends an opening instruction to the code scanning equipment, so that the code scanning equipment turns on a laser lamp and a camera according to the opening instruction; the detection platform sends an acquisition instruction to the code scanning equipment, so that the code scanning equipment acquires a screen image including a laser drop point formed by the laser lamp on a projection plate according to the acquisition instruction; the detection platform identifies whether the laser drop point in the acquired screen image is in a standard deviation ring or not: if so, judging that the coaxiality of the laser lampand the camera meets the production requirement. According to the invention, the installation coaxiality of the camera and the laser lamp can be automatically and rapidly detected, and the detectionresult is accurate and reliable; because the detection result does not depend on a code scanning head packaged in a centralized manner, the production and assembly cost of the code scanning equipmentis greatly reduced, and the large-scale popularization and application are facilitated.

Description

technical field [0001] The present invention relates to the technical field of production and manufacturing detection, in particular to a method and system for detecting the coaxiality of a code scanning device. Background technique [0002] In daily life, smart POS machines with code scanning functions, code scanning guns and other equipment are often used. These code scanning devices can scan the one-dimensional code or two-dimensional code of the product by using the scanning terminal to obtain the corresponding product information. Information. The laser light on the scanning dock will emit a specific shape to show the user the scanning range, and at the same time the flash light is on. Even in a dark environment, the user's sight can still quickly scan through the two dimensions of brightness and range. The code device is positioned on the one-dimensional code or two-dimensional code. [0003] At present, during the production and assembly process of the code scanning...
