With the improvement of industrial automation, the requirements for refined management of the production environment are becoming higher and higher. As an important visual management tool for production sites, ground markings are becoming increasingly important. In addition, with the development of intelligent manufacturing technology, 5A-level factory ground markings are also beginning to develop in the direction of intelligence and informatization. For example, automatic monitoring and management of marking areas can be achieved through intelligent recognition technology; real-time updating and sharing of marking information can be achieved through informatization systems. The application of these technologies will further improve the production efficiency and management level of the factory.

[0003] In order to reduce the waste of human resources, automatic marking equipment has appeared on the market, which can mark the ground along the set path. These automatic marking equipment have high marking efficiency and can greatly reduce the use of human resources. However, this automatic marking equipment has some defects, such as the need to manually replenish the paint liquid, and cannot achieve fully automatic liquid replenishment.

The automatic fluid replenishment method according to claim 8 or 9, characterized in that: The docking process of the docking component and the automatic ground marking painting equipment includes: The first driving member drives the supporting plate member to move upward in the vertical direction, so that the automatic ground marking brushing device abuts against the second pipe member. As the automatic ground marking brushing device moves upward, the second pipe member expands and contracts along the axial direction of the first pipe member. The movement of the second pipe member drives the first moving member to move, and the first moving member drives the valve body member to open, thereby realizing the connection between the first pipe member and the second pipe member. When the second pipe fitting is successfully connected to the automatic ground marking painting device, the first monitoring component is triggered and generates a connection success signal; In the case where the second pipe fails to dock with the automatic ground marking painting equipment, the first monitoring component is not triggered and generates a docking failure signal or does not generate a docking success signal.
