Embodiment 1
[0035] see figure 1 , for a product processed by a plurality of constituent units according to a preset processing flow (including multiple processes), this embodiment provides a whole-process quality traceability method, including steps:
[0036] Step 101, assign a unique two-dimensional code to each component unit of the product in advance.
[0037] Two-dimensional code is an information identification technology developed by combining the three technologies of computer, communication and photoelectric sensing. It is a black and white geometric figure arranged according to certain rules, and the black and white positions in the figure correspond to "1" and "0" respectively, thus forming a sequence of binary characters, which can represent numbers, characters and other information.
[0038] According to different quality traceability requirements and structural characteristics of different products, in this step, a corresponding QR code can be assigned to all the components ...
Embodiment 2
[0066] see image 3 For a non-combined product processed according to a preset processing flow (including multiple processes), since the product does not involve multiple constituent units and the transfer of information from the inner layer to the outer layer, this embodiment provides another A method for tracing the quality of a product throughout the process, comprising the steps of:
[0067] Step 301, assign a unique two-dimensional code to the product in advance.
[0068] Step 302, when entering the first designated process in the above processing flow, convert the two-dimensional code into a hole matrix code and then drill and set it on the current product.
[0069] It should be noted that the first specified process may be any process specified in the processing flow, and is not limited to the first process in the processing flow. In a specific implementation, the earliest process in the processing flow that will have a negative impact on the recognition of the two-di...

Abstract
The present invention relates to the field of product production, and discloses a product full-flow quality traceability method. A product is processed and prepared by a plurality of composition unitsaccording to a preset processing flow. The method comprises the steps of: respectively distributing one unique two-dimensional code to each composition unit; in a first assigned process in a processing flow, converting the two-dimensional codes to unique aperture array codes and then performing drilling arrangement of the aperture array codes on the corresponding composition units; in a second assigned process, reading one aperture array code on each composition unit, generating corresponding unique two-dimensional codes for the read aperture array codes, and converting the two-dimensional codes to the unique aperture array codes and then performing drilling arrangement of the unique aperture array codes to a composite structure formed by the composition units; and in a third assigned process, reading the aperture array codes on the composite structure, converting the aperture array codes to corresponding two-dimensional codes and then arranging the two-dimensional codes to the composite structure. The product full-flow quality traceability method can ensure that traceability identifiers can be easily and accurately read in the full process, can avoid loss of information of an inner layer and can achieve product life-cycle traceability.
Description
technical field [0001] The invention relates to the technical field of product production, in particular to a method for tracing the quality of a product throughout the process. Background technique [0002] Traceability of the cause of product problems is a serious challenge for manufacturers in every industry, from automotive to aerospace, from medical to food. In an era of globalization, businesses pursue relationship management to maximize customer satisfaction. Consumer and environmental regulations are becoming stricter, making traceability even more necessary. [0003] More than ever, manufacturers are looking to maximize production capacity and reduce costs. To achieve this goal, every step in the entire manufacturing process must be monitored and complete historical records kept. Issues affecting product quality must be quickly identified and corrected to prevent defective products from continuing down the production line, with the ultimate goal of achieving zero...
