Embodiment 1
[0061] 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:
[0062] Step 101, assign a unique two-dimensional code to each component unit of the product in advance.
[0063] 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.
[0064] 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
[0150] see Figure 12 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:
[0151] Step 1201, assign a unique two-dimensional code to the product in advance.
[0152] Step 1202, 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.
[0153] 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 tw...

Abstract
The invention discloses an efficient full-process product quality tracing method including the steps of assigning a unique two-dimensional code for each composition unit; in a first specified process,converting the two-dimensional codes into aperture array codes and drilling the aperture array codes in the corresponding composition units; in a second specified process, reading each aperture arraycode, and generating a corresponding unique two-dimensional code for each of all the aperture array codes, converting the two-dimensional code into an aperture array code and drilling the aperture array code in a composite structure formed by each composition unit; in a third specified process, reading an aperture array code on the composite structure, and converting the aperture array code intoa two-dimensional code and arranging the two-dimensional code on the composite structure. A method for conversion from a two-dimensional code to an aperture array code includes the steps of convertingthe two-dimensional code into a binary table, and dividing the binary table into at least two parts; converting each part into an aperture array code local graph; and combining all the aperture arraycode local graphs to obtain a complete aperture array code. According to the efficient full-process product quality tracing method, the two-dimensional code can be converted into the aperture array code with a smaller number of apertures, the processing workload is reduced, and it is effectively ensured that tracing markers are accurately identified.
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...
