Traditional test methods generally need to design a special test bench. auto production line adopts special test instruments and relies on manual operation and analysis, so the test preparation period is long, the test efficiency is low, the tip is poor, and the test results are easily unaffected by human factors. The rapid development and popularization of computer aided test, CAT) promotes the improvement of testing technology and provides a strong technical guarantee for product quality.

Signal-to-noise ratio of sensor. The ratio of signal power (SP) to noise power (NP) is expressed as SIN or SNR. Signal-to-noise ratio is an evaluation index reflecting the sensor's ability to detect signals. In order to make the sensor detect the small changes, the sensitivity of the sensor should be improved and the noise should be reduced.

Transmit the difference between the actual output value and the theoretical output value of the sensor. It can be expressed by formula, which is usually determined by statistical analysis of test results. When sensors are selected for automatic packaging line, on the premise of meeting the detection function and performance requirements (such as high measurement accuracy, high sensitivity, good reliability, strong anti-interference ability, etc.), it is also required to be small in size, convenient to install and replace, easy to maintain and repair, and not affect the normal performance of existing packaging line equipment.

Automobile automation production line manufacturers summarized the structural characteristics of auto production line

1. The whole machine adopts servo motor to control each device independently, which makes the movement of each device more stable and accurate, improves the running synchronization and greatly improves the overall efficiency.

2. The machine is easy to maintain, and the bottle type conversion is simple and quick

3. Glue evenly and the length of glue can be adjusted.

4. The design of safety system is reliable, stable and durable.

5. The touch screen is easy to operate and flexible to switch. In the computer-aided test system, auto production line uses automatic test equipment and devices (ATE) to carry out the process or final quality inspection and quality assurance experiments. CAT system is usually an automatic test and analysis system composed of intelligent instruments, computers and their peripheral devices with standard communication interface bus and supported by software such as test and analysis processing. A typical CAT system usually takes an emblem computer as the core, and is equipped with corresponding external equipment such as testing instruments, data acquisition units, terminals, printers and plotters, and test application software. Therefore, CAT system has greater flexibility, stronger versatility and better performance-price ratio than special test signal processing equipment (such as FFT analyzer, sound intensity tester, etc.), which is generally composed of microprocessor.
