High-temperature kiln product sorting and tracing method and system based on two-dimensional code nameplates

Abstract

The invention relates to a high-temperature kiln product sorting and tracing method and system based on two-dimensional code nameplates. By the provided method and system, high-temperature kiln products can be automatically sorted and traced. According to the technical scheme, the high-temperature kiln product sorting and tracing method based on the two-dimensional code nameplates comprises the following steps: (1) associating products with the two-dimensional nameplates; (2) placing the two-dimensional nameplates on the products, and enabling the two-dimensional nameplates and the products to move forwards along an assembly line; (3) arranging two-dimensional recognizing devices on a sorting opening of the assembly line, sorting the products, and feeding the products into a high-temperature kiln for firing; and (4) finding out the associated products, and tracing the products in batches. The sorting and tracing system comprises a computer, the two-dimensional nameplates, at least one first two-dimensional code recognizing device and a plurality of second two-dimensional code recognizing device. Each two-dimensional code nameplate for sorting and tracing of products of the high-temperature kiln comprises a substrate, a code tagging region is arranged in the middle of a top surface of each substrate, and a two-dimensional code is arranged in each code tagging region.

Description

technical field [0001] The invention relates to the technical field of traceability systems, in particular to a batch sorting and traceability method based on a two-dimensional code nameplate and a batch sorting and traceability system based on a two-dimensional code nameplate in the production of a high-temperature kiln mixed assembly line. Background technique [0002] The high-temperature kiln assembly line is usually used for firing magnetic devices (such as magnetic cores, magnetic rings), ceramics and other products. According to the batch information, it can be traced back to the information of people, machines, materials, methods, and environment during the processing of the previous process. [0003] At present, in this relatively complex production environment, there are certain difficulties in product traceability. The main reasons are as follows: [0004] 1. If figure 1 As shown, the product production adopts the method of mixed assembly line, that is, the mate...

Problems solved by technology

[0009] 2. Because there is no color difference between the mark produced by engraving and the nameplate itself, it is impossible to sort by identifying the nameplate number, and only by identifying the shape of the product at the sorting port to determine the kiln to enter;

[0010] 3. After leaving the kiln, manually record the nameplate mark to record the corresponding batch number. Also, because there is no color difference between the mark produced by engraving and the nameplate itself, it cannot be entered by scanning;

[0011] The defects of the above-mentioned traceability method are: 1) because the product shape is used for sorting, when the batch granularity is very fine (such as different presses with different batches), it is impossible to realize the sorting by batch; 2) due to the need to compare with the standard library Yes, so there is a requirement for easy identification of the product shape, and the product types should not be too many, and the versatility is poor; 3) The recording efficiency after leaving the kiln is low and error-prone
