Through experiments, problems can be exposed, fault sources can be found out, and then improvement measures can be taken, so that the reliability of automated assembly line products can be increased. Automobile automation production line manufacturers have sorted out the following types of automated assembly line tests:

(l) specially arranged reliability growth tests conducted in laboratories, which can find problems early, but the cost is relatively high.

(2) Use performance test, function test, environmental test and environmental stress screening test to find problems. Because this kind of test is not specially designed for reliability, some exposed problems are often ignored and the feedback is not timely enough. We should vigorously promote "comprehensive utilization of tests" in order to achieve the purpose of reliability growth. However, it is necessary to establish a sound information closed-loop system and implement effective fault collection, feedback and monitoring.

(3) Combination of infield test and outfield application. This kind of test is more suitable for the reliability growth of "under research" and "in service" automated assembly line equipment. For products that have great influence on safety and task success, carry out growth test in laboratory. Other products are growing in field use.

(4) In the design of auto production line, various environmental impacts that may be encountered in the whole life cycle of products can be found out, such as impact and vibration during assembly, transportation and shooting, drop-in, drop-out, bacteria spreading during storage, and climate, dust and vibration during Sichuan. Therefore, we must carefully choose the design scheme and take necessary protective measures to reduce or eliminate the harmful effects on the environment.

Specifically, we can understand and control the environment, not only the working environment and maintenance environment of the product, but also understand that both single environment and combined environment must be considered in the process of product design and experiment, which refers to the natural environment where the installation is located. When conditions permit, we should create a good working environment for the designed parts in a small range, or artificially change the environmental factors that are unfavorable to the reliability of the product. Adapting to the environment means taking measures in design scheme, material selection, surface treatment, coating protection, etc. when all environmental conditions cannot be controlled artificially, so as to improve the environmental resistance of mechanical parts.

Artificial intelligence technology is a new science and technology that enables computers to simulate some thinking processes and intelligent behaviors of human beings (such as learning, reasoning, thinking, planning, decision-making, etc.). Artificial intelligence is a branch of computer science, which attempts to understand the essence of intelligence and produce a new intelligent machine that can respond in a similar way to human intelligence.
