碩士 === 國立高雄科技大學 === 電子工程系 === 107 === The government has strongly promoted the concept of Industry 4.0 in recent years. Many industries have begun to transform and move toward the goal of unmanned factories. A great deal of efforts had paid to replace traditional manpower with robotic arms or automated machines on production line. However, enterprises are focusing on technical computer applications. The development of testing of consumer electronics parts is less concerned in the automated innovation. Especially in the production of consumer electronics control panels, fully automated functional testing is still difficult to achieve. Many small to medium sized enterprises are developing small-volume production of a wide range of different items. The functions of each product are different. It is necessary to manually check whether the function is normal or not, and it takes too much labor cost. On the other hand, a fully automated testing approach requires a large number of different functional test equipment. It will cost too much for the cooperative. This thesis mainly focuses on the design of a scalable automatic detection system at low cost to reduce the cost of transformation in production test, to speed up the test process, to lower personnel cost, and to record abnormal data for analysis to improve production yield. This study uses Microchip’s PIC16F1947 controller chip to implement the experimental board, uses C language to write control function program at PC-end. On the main board, there are pre-designed simulated analog temperature output, power communication module, transistor communication module, AC/DC power detection module, stepper/ DC motor control verification module, short circuit detection module, DC 0-10V input detection, DC 12V output, and so on, covering features of most air conditioning, freezing/ cold storage control boards. It reserves multiple sets of SPI communication interfaces for subsequent expansion. To provide subsequent expansion of stable power supply, the design is to supply power by switching power. Java language is used to design PC-side human-machine interface for improved system portability. The main board has a record function for information such as production date, model and fault type. The related production information is exported into the database for analysis and improvement. To the data can be applied to the development product, the action logic is pre-designed. It has been found through experiments that automatic testing is very important. In addition to improving production speed and yield, it can improve the overall production line operation schedule effectively. On the other hand, transferring manpower away from the repetitive and troublesome working environment improves the productivity of employees. The overall working environment can be improved. At the same time, the company’s reputation can be strengthened due to the effective monitoring and improvement of product quality.
