In the production process of air heating core, it is crucial to establish a perfect quality traceability system to ensure product quality, improve production management level and deal with possible quality problems.
First, the raw materials are finely identified and managed. Each batch of raw materials entering the air heating core fully automatic assembly line, whether it is a metal heat sink, heating wire or insulation material, must be given a unique code. This code covers key data such as the supplier information, purchase date, batch number, etc. of the raw materials. At the starting end of the air heating core fully automatic assembly line, the raw materials are identified and entered by scanning the code or radio frequency identification (RFID) equipment, so that they enter the database of the quality traceability system, and their initial state and the time node of entering the assembly process are recorded.
Secondly, data collection points are set in each key process link of the air heating core fully automatic assembly line. For example, in the heating wire winding process, the number of turns and tension data of the winding are recorded; in the heat sink assembly process, the position accuracy and pressure parameters of the assembly are collected; in the welding process, the welding current, voltage and duration information are stored. These process data are closely related to the individual number of the air heating core being assembled, forming a detailed production process data chain. Once a product has quality defects, these data can be used to accurately locate the process link where the problem may occur.
In addition, use automated testing equipment to conduct comprehensive performance testing on the assembled air heating core. Testing equipment such as resistance testers and voltage testers strictly control the electrical and insulation properties of the product. The test results are automatically transmitted and stored in the database with the product number. For unqualified products, not only can they be quickly sorted, but also the specific items and related test data of their unqualified products can be recorded in detail to provide a basis for subsequent quality analysis.
In addition, a centralized quality traceability database is established. All information related to the quality of the air heating core, including raw material information, production process data, test results, etc., are integrated into this database. Through the unique number of the product, the complete quality information track of the product can be quickly queried in the database, realizing the quality traceability of the whole life cycle from raw material procurement to finished product delivery.
In terms of personnel management, employees operating the air heating core fully automatic assembly line are identified and their operation records are registered. Record the operation time, operation content, and parameter adjustment of employees in each process. When quality problems occur, it is possible to check whether there are improper human operation factors and clarify the responsibility.
At the same time, the equipment of the air heating core fully automatic assembly line is regularly maintained and calibrated. The operating status and accuracy of the equipment have a direct impact on product quality. The maintenance and calibration records are included in the quality traceability system so that the impact of equipment factors can be comprehensively evaluated when quality fluctuations occur.
Finally, through in-depth analysis and mining of data in the quality traceability system, the production process and quality control measures are continuously optimized. Analyze the trends and patterns in the quality data, discover potential quality risk points, and adjust the raw material procurement standards, equipment parameters or production processes in a timely manner, so as to continuously improve the product quality of the air heating core, ensure the efficient and stable operation of the air heating core fully automatic assembly line, and meet the market demand for high-quality air heating cores.
