[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] As Figure 1 shown, the bulkhead production line of the present invention includes two single-plate bulkhead production lines 1 and one panel bulkhead production line 2. It is used for the automated production of bulkhead sheets of luxury cruise ships. There is a safety passage 3 between the single-plate bulkhead production line 1 and the panel bulkhead production line 2. The single-plate bulkhead production line 1, the panel bulkhead production line 2 and the safety passage 3 are parallel to each other, and the material flow forward directions of the single-plate bulkhead production line 1 and the panel bulkhead production line 2 are the same.

[0022] Specifically, referring to Figure 2 shown, the panel bulkhead production line 2 includes 8 workstations arranged in sequence according to the material flow forward direction. The working process of this production line is: raw material loading → automatic panel welding → grinding and scribing → installation of longitudinal stiffeners in the same direction → robotic automatic welding of stiffeners → mechanical straightening → manual installation of strengthening profiles → robotic welding of profiles → manual inspection and loading. The corresponding workstations are: panel splicing and elongation workstation 21, which is used for automatic panel welding of the steel plates for manufacturing bulkheads; grinding and scribing workstation 22, which is provided with a grinding system, a scribing system, a gantry and a first workstation conveying platform, and is used for grinding the primer at the assembly line of the steel plates for manufacturing bulkheads, and scribing the assembly line and spraying codes on the ground steel plates; panel bulkhead stiffener installation workstation 23, which is used for automatically lifting the stiffeners required to be set on the steel plates longitudinally or transversely, automatically pressing down the stiffeners to adjust the assembly gap, and manually positioning and spot welding; panel bulkhead stiffener robotic welding workstation 24, which is used for double-wire MAG welding of the stiffeners set on the steel plates; panel bulkhead correction workstation 25, which is used for automatically monitoring the deformation amount of the steel plates transferred to the correction workstation 15 after the above welding and automatically starting the corresponding upper pressure roller or lower driving roller for pressure correction; panel bulkhead manual assembly workstation 26, which is used for manual welding of the strengthening profiles; panel bulkhead robotic welding workstation 27, which is used for welding the cross profiles installed later; manual inspection and loading workstation 28, which is used for repairing and blanking and loading the bulkheads obtained by the above steel plate welding.

[0023] AsFigure 3 As shown in the figure, the veneer enclosure production line 1 includes 8 workstations. The working process of the veneer enclosure production line 1 is as follows: raw material loading → grinding and marking → splitting into two lines A and B → installing longitudinal members in the same direction → robot automatic welding of longitudinal members → merging of lines A and B → mechanical straightening → manual installation of strengthening profiles → robot welding → manual inspection and loading onto trays. They are arranged in sequence according to the forward direction of the logistics: First is the marking and grinding workstation 11, which consists of four parts: a grinding system, a marking system, a gantry, and a conveying platform. It is mainly used for primer grinding at the steel plate assembly line and marking the assembly line and spraying codes on the ground steel plate. This workstation is equipped with a manual touch terminal for manual determination of the current task, retrieval of the corresponding task package file, and import into the various dedicated machine systems equipped at the current workstation.

[0024] Second is the splitting and transverse movement workstation 12. The sheet after grinding and marking is split through this workstation and transferred along two production lines. This workstation is composed of a conveying roller path and a liftable conveying chain. When the first sub-production line needs to transverse a workpiece, the conveying chain rises to transverse the workpiece to the second sub-production line. After the conveying chain descends, the workpiece will fall back onto the platform.

[0025] Among them, the two sub-production lines are respectively arranged in sequence according to the forward direction of the logistics: the veneer enclosure longitudinal member installation workstation 13, the longitudinal member robot welding workstation 14, and the transfer unit: The veneer enclosure longitudinal member installation workstation 13 includes an assembly service gantry, which is used for automatically lifting the longitudinal members required to be set on the steel plate longitudinally or transversely, automatically pressing down on the longitudinal members to adjust the assembly gap, and manual positioning spot welding; The longitudinal member robot welding workstation 14 is used for double-wire MAG welding of the longitudinal members set on the steel plate; The transfer unit is used for converging the steel plates flowing on the two sub-production lines and converging the steel plates flowing on the two sub-production lines to the forward direction of the logistics.

[0026] Then comes the longitudinal member robot welding workstation 14, which mainly completes the welding function of the longitudinal members. This workstation is equipped with a longitudinal member robot welding platform, a robot welding gantry, an automatic welding double-wire MAG system, a vision system, a robot control system, etc. The workpiece is scanned through the vision system, and the robot automatically programs and creates a welding path through software recognition and guides the robot to complete the welding of all welds.

[0027] Fifth is the straightening station 15, which is equipped with a straightening machine and a fifth-station conveying platform; the straightening machine is equipped with 2 groups of upper pressure rollers and 1 lower driving roller; each upper pressure roller adjusts the distance between it and the lower driving roller through an upper pressure roller reduction motor, an upper pressure roller gear, and an upper pressure roller rack, and the lower driving roller adjusts the distance between it and the upper pressure roller through a lower driving roller reduction motor, a lower driving roller gear, and a lower driving roller rack. The straightening station 15 is also provided with an infrared monitoring system for automatically monitoring the deformation amount of the steel plate transferred to the straightening station 15 after welding and automatically starting the corresponding upper pressure roller or lower driving roller for pressure straightening.

[0028] Sixth is the manual assembly station 16, which is equipped with a conveying platform and a welding auxiliary cantilever. The welding auxiliary cantilever is equipped with manual spot welding equipment for manual welding and assembly of cross-shaped profiles.

[0029] Seventh is the robot welding station 17, which is mainly used to complete the welding function of the post-installed cross-shaped profiles, including several main systems such as a welding platform, a robot welding gantry, a welding system, and a robot control system. The workpiece model is imported into the programming software through offline programming to generate a welding program containing paths and processes, guiding the robot to complete the welding of all welds.

[0030] The last station is the repair, grinding, and transfer station 18, which is mainly used for the repair and blanking and disk loading of the bulkhead obtained by welding the above steel plates. It is equipped with a disk loading gantry, a welding cantilever, and a conveying platform. The bulkhead can be lifted from the platform by a blanking gantry and loaded into the bulkhead tray to realize the repair / grinding / transfer station and related logistics transportation.

[0031] As Figure 2 shown, the panel bulkhead production line 2 includes 8 stations. This production line is basically the same as the single-panel bulkhead production line 1, with the main difference being in the grinding and marking station 22. There is a panel splicing and lengthening station 21 in front of the grinding and marking station 22, which is mainly used for automatic splicing, automatic milling, and double-wire MAG welding of the steel plate sheets after hoisting and feeding. This station consists of several main parts such as a feeding gantry, a hydraulic pressing device, a steel plate hydraulic positioning device, a milling edge device, a double-wire MAG welding system, a video monitoring system, and a support platform. It can realize functions such as automatic panel splicing, automatic milling, and automatic welding of steel plates with different thicknesses through scanning the plates by the video monitoring system.

[0032] In the above pipeline system, in the automatic panel splicing and lengthening station, after the plate is hoisted and fed and its position is adjusted and determined by the infrared alignment system and the steel plate hydraulic positioning adjustment device, the steel plate is fixed by pressing down through the piano key hydraulic system, and then the high-speed milling device mills both sides of the steel plate, and finally the double-wire MAG welding is used to weld the panel joint. A welding control system is equipped during welding to perform laser tracking and positioning of the weld seam and control its quality.

[0033] The described grinding and scribing station can import model information through AM software, and the system automatically plans the grinding and scribing paths according to the model features to ensure the accurate progress of subsequent welding and assembly processes.

[0034] The robot double-wire MAG welding technology adopted in this application configures a double-wire welding system, a water-cooling device, a laser tracking system, and a pulsed welding digital power supply, and performs high-speed welding at a welding speed of more than 1000 mm / min, which can effectively control the deformation of thin plates.

[0035] The production line of this application also includes an information system, which is set in the centralized control room. This system is highly integrated and has complete functions. Through the operation interface of the intelligent control system of the whole production line, it realizes the production monitoring of all workstations, the logistics transportation management, and the automation line, robot welding, and deformation detection. It realizes the remote automatic control of the workstations, automatically generates work logs and alarm logs, and can communicate with the MES system, receive production task information, coding information, and design data of workpieces issued by the workshop MES, etc. Through the interaction interface of the provided data-driven system software, it realizes the automatic control of each workstation.

[0036] In the above production line, for the paneled bulkhead production line 2, the minimum specification of the paneled bulkhead is the same as that of the single-panel bulkhead, and the maximum longitudinal paneling specification of the paneled bulkhead production line 2 is the same as that of the single-panel bulkhead. The maximum transverse paneling specification is 16000*5500*25 (mm).

[0037] In one implementation, the main production method of the stiffener robot welding station 14 adopts advanced vision recognition technology, artificial intelligence technology, and a process expert database system to achieve intelligent fully automatic welding. Specifically, it scans the workpiece through a vision system, and then the robot identifies and completes the welding of all welds through software. The welding process expert knowledge base supporting the production line used therein can automatically match the welding parameters during the robot welding process according to information such as fillet weld form, weld width, and base material type.

[0038] Those of ordinary skill in the art can understand that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
