Technical Field

[0001] The utility model relates to the technical field of product assembly intelligent guidance, in particular to an intelligent manufacturing production guidance controller. Background Art

[0002] In the traditional production model, a production line can only produce products of one specification, but now on the digital intelligent production line, different products can be produced online at the same time according to different order requirements. On the entire production line, each product has a unique identity barcode. At each workstation, workers need to scan the barcode to confirm the model and specifications of the product, and then retrieve the corresponding operation instruction document to produce according to the process requirements. This requires staff to be familiar with the production process of various types of products, familiar with the placement and accurate identification of the required materials, and assemble strictly in accordance with the operating sequence. It is common for parts to be missing, wrongly installed, and repeatedly disassembled and assembled during the assembly process, and the workload of operators is also relatively high.

[0003] In order to ensure production efficiency on the production line, the production time of each workstation must be strictly followed. When the product model is changed, the production efficiency will be affected. Therefore, how to improve production efficiency, ensure product quality, and reduce the labor intensity of operators is an urgent problem to be solved in the improvement of enterprise refined management.
