Intelligent robot controller for hydrothermal forming of hull panel is a modern control tool with high technical level and machine gun characteristics in ship production, which is particularly important for ship safety.
However, there is still a big gap in the research of this project in our country, which makes the existing research results relatively small and can not play a good practical guidance. In this paper, the working principle of intelligent robot controller for hydrothermal forming of hull panel is described in detail at first, then its overall structure and corresponding technical requirements are discussed in detail. Finally, the software and hardware systems are analyzed to provide help for related research. Practical research abroad has proved that hydrothermal forming technology of hull panel can not only be applied in complex working environment, but also play a good role in ensuring the quality and progress of ship production.
Therefore, it is favored by foreign shipbuilding industry. Relevant research started earlier and has achieved a series of remarkable results. Up to now, there are still relatively few experts and scholars engaged in this technology research in China, which can not meet the rapid development needs of China’s shipbuilding industry.
Therefore, the research of intelligent robot controller for hydrothermal forming of hull panel will become one of the hot topics in the current and future. The corresponding research carried out in this paper has a strong timeliness and practical significance. Intelligent robot for hydrothermal forming of ship hull plate is an artificial intelligence robot working under special working conditions.
After analyzing the relevant research data abroad, it can be seen that the working principle of the robot controller is mainly to measure the steel plate in the process of ship production through its own laser measuring system, and then the measured results are transmitted to the advance through wireless communication network. In the reporting system, the expected data set in advance are compared with the measured results in the field, so as to determine the precise processing position, overheating time and cooling speed of the steel plate required by the ship. Subsequently, the above parameters are uploaded to the intelligent robot controller for hydrothermal forming of ship hull plate, and the related operations are carried out by using the manipulator under its precise control.
The intelligent robot controller for hydrothermal forming of ship hull plate adopts gantry structure and moves horizontally along two parallel guideways during the working process of the controller.
When it reaches the preset working position, the ship’s steel plate processing should be in the middle of the guideway at this time. On top of the gantry, a movable processing cart is set, and its moving direction is vertical to the guide rail, that is, the processing cart moves vertically. At the same time, there are heating nozzles and cooling nozzles at both ends of the nozzle. The number of nozzles is adjusted according to the actual demand of ship production and processing. Usually, the heating sprinkler and cooling nozzle should keep linkage, that is, after a certain distance of hot working, the steel plate is sprayed with cooling nozzle to realize the cooling of the steel plate.
In this process, the principle of thermal expansion and cold contraction should be fully utilized to make different stress interactions in the steel plate, and ultimately achieve the purpose of bending deformation of the steel plate.
On the operating platform, a high accuracy and non-contact laser measuring instrument will be set up to measure the discrete points in real time during the steel plate processing, and correct the deviation in time, so as to promote the steel plate processing to achieve the desired working objectives. Because hydrothermal forming intelligent robots for hull panels usually need to work under harsh working conditions, foreign shipbuilding enterprises attach great importance to their technology research, and their various technical requirements gradually form a complete standard. When the surface of the processed steel plate is measured by a laser measuring instrument, the sum of the total measuring time of the discrete points is less than 15 minutes. Because the robot mainly serves the ship production, the software system of its controller adopts the dual software program framework of system program and user program. Its contents are as follows: (1) wireless communication between the host computer and the operating instruments and equipment of the intelligent robot for hydrothermal forming of hull panel; (2) compiling and executing the program instructions issued by users; (3) real-time online self-monitoring, timely troubleshooting and human-machine interaction with users by using its own preset operating procedures; (4) presenting the intelligent robot for hydrothermal forming of hull panel on the display of control terminal. Front running state; (5) Correct and guide operators to use intelligent robots correctly in time.
The hardware system of the intelligent robot mainly includes the following four parts: (1) motor part. Because the intelligent robot for hydrothermal forming of hull panel needs to have high power to support, and has high requirements for the accuracy of operation, its motor adopts servo and stepping motors as the main driving structure. (2) The generalized input/output part.
In the hardware system of the controller, two input boards and one output board are used to collect, communicate and transmit external signals during the operation of the intelligent robot. (3) Operating instrument part. Because the intelligent robot needs interpersonal interaction function and assistant user to process fault information, it mainly includes LCD display screen and corresponding function operation keys which can display various process parameters, operation instructions, fault processing and other information. In summary, as an indispensable tool for the future shipbuilding industry, the hydrothermal forming intelligent robot for hull panel has high research and application value.
