Description

Technical Field

[0001] The invention relates to the technical field of production line guidance systems, in particular to an audio-visual guidance method for a manual feeding production line. Background Art

[0002] In the automotive parts industry, with the maturity of robot automatic loading technology in recent years, more and more traditional manual loading work has been replaced by robots. However, under current technical conditions, robots cannot independently complete the entire loading process, and workers are still required to do some sorting and sorting work at the conveyor belt and stacking rack stations. Compared with the original manual loading work mode of dedicated personnel and dedicated machines, the number of loading stations that workers on the production line need to be responsible for has increased significantly under the current mode. At the same time, the number of workpieces that can be cached at each conveyor belt and stacking rack station is not the same, and the number of cached workpieces consumed during the production process is also different. In order to ensure that each station has cached workpieces and the production line can operate normally, workers are required to complete the operation of each station accurately and quickly in a specific process sequence. This is often difficult to achieve when the current turnover rate of production workers has increased significantly and the number of skilled workers in the factory has decreased. In actual production, workers often miss the operation of a certain station, or do not understand the operation of a specific station, resulting in low work efficiency and the equipment start-up rate cannot reach the expected value.

[0003] The present invention discloses a sound and picture guidance method for a manual feeding production line. Through various methods such as sound, picture, and operation restriction, the feeding work of the operator can be guided, prompted, and warned in the equipment such as a conveyor belt production line and a stacking rack. It ensures that the front-line operators can complete the feeding work according to the prescribed process. Under the premise of maintaining the front-line staff without increasing, the system automatically distributes and guides the feeding work, reduces the loading jams and line stoppages caused by problems in the sequence of manual operation processes, and ensures the production line operation rate.
