Assembly line production, also known as assembly line production operations, refers to the labor object according to a certain process route and unified production speed, continuously through each work place, in order to process and produce products. It is the further development of the object specialized organization form, and it is a production organization form with finer division of labor and higher production efficiency. So what standards should we do for product quality in the production process of assembly line equipment? 1. Do not accept unqualified products Do not accept unqualified products means that employees before production and processing, the first to pass the products according to the regulations to check whether it is qualified, once found the problem has the right to refuse to accept, and timely feedback to the previous process. The former process personnel need to stop processing immediately, trace the cause, and take measures to find and correct the quality problems in time, and avoid the waste caused by the continued processing of unqualified products. 2. Do not manufacture unqualified products Do not manufacture unqualified products means that after accepting the qualified products in the previous way, strictly implement the operating specifications during the processing of this post to ensure the processing quality of the products. The preparation work such as inspection and confirmation before operation is fully in place; Pay attention to the process conditions of the operation with the wild bird, avoid or early detection of abnormal occurrence, reduce the probability of producing unqualified products. Being well prepared and confirmed in the process is the key to not manufacturing nonconformities. Only by not producing defective products can it be made possible not to flow out and not to accept defective products. 3. No discharge of nonconforming products No discharge of nonconforming products means that employees complete the processing of this process and need to check and confirm the quality of products. Once defective products are found, they must stop the machine in time, cut off the defective products in this process, and complete the disposal of defective products in this process and take preventive measures. This process should ensure that the delivery is a qualified product, will be rejected by the next process or "customer". In order to ensure that the three principles are achieved, three inspections are also needed.
