    1. Check function:
    Quality control is the most basic function of quality inspection, which can also be called quality assurance function. This function exists as soon as quality inspection appears. In the past and now, even in the future when production automation is highly developed, the means and technology of inspection may develop and change, and the role of quality inspection is still indispensable.

    2. Preventive function:
    The important difference between modern quality inspection and traditional inspection lies in that modern quality inspection not only plays the role of checking, but also plays the role of prevention. In a broad sense, the incoming inspection of raw materials and purchased parts and the inspection of the previous process can prevent the subsequent production process and the production of the next process.

    3. Reporting functions:
    The function of reporting is also the function of information feedback. This is to enable leaders and relevant quality management departments to timely grasp the quality status in the production process, evaluate and analyze the effectiveness of the quality system. In order to make correct quality decisions and understand the changes in product quality and existing problems, the inspection results must be fed back to the leading decision-making departments and relevant management departments in the form of reports, so as to make correct judgments.

    4. Improved functions:
    The participation of quality inspection in quality improvement is the key to give full play to the role of quality inspection in quality control and prevention, and it is also the concrete embodiment of the participation of inspection departments in improving product quality. Quality inspectors are generally engineering technicians or skilled workers with certain production experience. They often work at the production site, and have the clearest understanding of the factors affecting people, machines, objects, laws, environment and other factors in production, and the most well-informed quality information. They know more about quality than designers and technicians, so they can put forward more practical suggestions and measures in quality improvement, which is also the advantage of quality inspectors.

    The function of quality inspection is mainly reflected in the inspection control function, prevention function and reporting function. Therefore, the quality inspector is required to be careful enough to ensure that each product entering the market is qualified. Therefore, the quality inspector should strictly comply with the relevant functional requirements, do his own work and control the safety and quality.

    The first function is the check function, which is also the most basic and important function in quality inspection. However, with the progress and development of the times, the means and technology of inspection are also slowly changing, so different companies have slightly different requirements, but their ultimate goal is to ensure the absolute quality and ensure that the products are 100% qualified. The second function is the prevention function, for example, through the measurement and control of process capability to prevent or through patrol inspection to prevent unqualified products. The third function is the reporting function, which requires the quality inspector to report and feed back to the superior leaders in time after finding problems, so that effective remedial measures can be taken as soon as possible.

    1. Check function
    That is, according to the requirements of technical standards and specifications, carry out multi-level inspection and experiments on raw and auxiliary materials, in-process products, semi-finished products, finished products, equipment, tooling, etc., so as to avoid putting unqualified products into production or transferring them to the next process or leaving the factory, so as to ensure the quality and play the role of “check”. Only through inspection and strict control, can the quality of products be ensured, such as non-conforming raw materials are not put into production, non-conforming semi-finished products are not transferred, and non-conforming finished products are not delivered.

    2. Prevention function
    The function of preventing and reducing products that do not meet quality standards can be realized through the following activities:
    a. First article inspection and patrol inspection.
    b. Incoming inspection, intermediate inspection and completion inspection.
    c. Measurement of process capability and use of control chart.

    3. Reporting function
    The reporting function is also the function of information feedback. Record, analyze, master and evaluate the actual quality level of products by recording, analyzing, mastering and evaluating the original data obtained from quality inspection. The report is fed back to the management decision-making department and relevant management departments in the form of report, so as to make correct judgments and take effective decision-making measures. The reporting function provides necessary information for cultivating quality awareness, improving design, strengthening management and improving quality.
