Description

[0002] Ships are composed of many parts, which can be summarized into three main parts according to their functions and uses: hull, power plant, and electrical system.

[0003] The hull is the basic part of a ship and can be divided into the main body and the superstructure. The main body generally refers to the part below the upper deck. It is a hollow body with a specific shape enclosed by the hull (bottom and sides) and the upper deck. It is the key part to ensure that the ship has the required buoyancy, navigation performance and hull strength. The hull is generally used to house the power plant, load cargo, store fuel oil and fresh water, and house various other compartments.

[0004] However, most existing ship hull plate welding processes use a single laser welding head to weld one side of two plates. To perform double-sided welding, the parts need to be manually flipped, which not only increases labor intensity but also makes it easy for welding accuracy to decrease due to human error.

The output shaft of the second rotary motor is connected to the Mag welding head.

[0015] A welding process for high-precision ship welding equipment, the details of which are as follows: S1. First, several component ship plates are placed on the welding table. The limiting plate is used to initially position the ship plates to ensure that they are in the correct position. Then, the horizontal motor is started. The horizontal motor drives the drive component to rotate. The drive component drives the drive plate to move through the transmission assembly consisting of the first rotating shaft, the first connecting block, the connecting column, the second connecting block, and the second rotating shaft. The drive plate then drives the first mounting plate to move, so that the clamping plate clamps and fixes the ship plates together. Under the pushing force of the clamping plate, the side walls of multiple ship plates are pressed together. S2, firstly, the Mag welding robot is moved to a suitable position by the moving component at the lower end of the Mag welding robot to perform Mag welding on the ship plate body. Then, the laser welding robot is moved to a suitable position by the moving component, and the laser welding head is driven to weld the upper end face of the ship plate body. After the welding is completed, the cylinder is started. The cylinder drives the limit block to slide in the limit groove. The clamping plate and the ship plate body are lifted by the first mounting plate. At this time, the Mag welding robot and the laser welding robot are in the same way as above. Under the action of the first rotary motor and the second rotary motor, the laser welding head and the Mag welding head on the Mag welding robot rotate 180 degrees to weld the lower end face of multiple ship plates body. S3. During the entire welding process, the pump starts, and the first and second dust suction ports draw in the waste gas generated during welding. The waste gas enters the treatment box through the first fitting and the first pipe. Inside the treatment box, the waste gas is adsorbed by the adsorption screen, and harmful substances are adsorbed. The purified air is discharged through the exhaust fan and then discharged to the outside through the air diffusers and filters on both sides of the welding table.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: In this invention, the horizontal motor in the horizontal drive component precisely drives the drive plate to move through the linkage of a transmission assembly, namely the first rotating shaft, the first connecting block, the connecting column, the second connecting block, and the second rotating shaft. This enables the clamping plate to stably clamp the ship's plate. The clamping plate uses an elastic plate and is equipped with anti-slip rubber, which ensures clamping force while preventing damage to the plate surface. This ensures the plate remains in a fixed position during welding, reducing welding errors caused by plate movement and thus improving welding accuracy. After welding one side, the cylinder of the lifting component drives the limiting block to slide within the limiting groove. The first mounting plate then automatically lifts the clamping plate and plate without manual intervention. Subsequently, the rotary motors of the laser welding robot and the Mag welding robot drive the welding head to rotate 180 degrees to weld the lower end face of the plate. The entire process is automated, significantly reducing labor intensity compared to manual flipping, while effectively avoiding errors caused by manual operation. This significantly improves the efficiency and accuracy of double-sided welding. Welding robots are positioned at both ends of the welding table, allowing for flexible selection of appropriate welding methods based on the material, thickness, and welding requirements of the ship's plates. For thin plates or areas requiring high welding quality and strict weld aesthetics, laser welding robots are used, leveraging the concentrated energy, small heat-affected zone, and minimal welding deformation of laser welding to ensure welding quality. For thicker plates or areas requiring greater penetration, Mag welding robots are used. Their gas-shielded welding method meets the needs of thick plate welding, improving welding efficiency. Mag welding precedes the initial preheating and root pass welding of the plate, while laser welding follows for deep penetration welding, enhancing both welding quality and efficiency. The two robots work together, allowing for optimal selection for different welding conditions. This not only improves welding efficiency but also ensures that different types of plates achieve the best welding results, enhancing the overall welding quality of the ship's hull.

[0017] This invention utilizes a dust-collecting component. The first and second dust-collecting ports, operated by a pump, collect waste gas generated during welding from all directions. The waste gas enters a treatment chamber through a first pipe fitting composed of a second pipe, a flexible hose, a third pipe, and a fourth pipe. Inside the treatment chamber, an adsorption screen adsorbs harmful substances in the waste gas, such as metal fumes and harmful gases generated during welding. The purified air is then discharged by an exhaust fan and passes through vents and filters on both sides of the welding table, effectively reducing pollution of the working environment and protecting the health of operators. Simultaneously, an anti-clogging mechanism, with an anti-clogging motor driving a ball screw, moves a cleaning plate left and right within the treatment chamber. A brush cleans the adsorption screen in real time, preventing blockage due to impurities. This ensures continuous and efficient operation of the dust-collecting component, reducing equipment maintenance frequency and extending equipment lifespan. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8The present invention provides a technical solution: a high-precision ship welding equipment, comprising, A laser welding robot 1 is equipped with a first rotary motor 2 at one end of the laser welding robot 1, and a laser welding head 3 is connected to the output shaft of the first rotary motor 2. Welding table 4, several ship plate bodies 5 are placed on the upper end of welding table 4. Two symmetrically distributed clamping plates 6 are movably provided on the upper wall of welding table 4. The clamping plates 6 are driven to move horizontally by a horizontal driving component to apply a horizontal force to several ship plate bodies 5. After clamping several ship plate bodies 5, the upper end face is welded. The clamping plates 6 are also driven to move vertically by lifting components provided on both sides of welding table 4 to lift the ship plate bodies 5 after single-sided welding. After lifting, the lower end face of the ship plate bodies 5 after multiple upper end face welding is welded. Welding table 4 is also provided with a dust collection component to adsorb and treat the exhaust gas during welding. Two symmetrically distributed limiting plates 7 are also provided on the upper end of welding table 4. Mag welding robot 8 and laser welding robot 1 are located at one end of welding table 4, and Mag welding robot 8 is located at the other end of welding table 4. Both laser welding robot 1 and Mag welding robot 8 have moving components at their bottom ends.

[0021] The clamping plate 6 is an elastic plate, and anti-slip rubber 9 is installed on the wall of the clamping plate 6 near the ship plate body 5. The horizontal drive component includes a horizontal motor 10, a drive component 11 fixedly connected to the output shaft of the horizontal motor 10, a first mounting plate 12 fixedly connected to one end of the clamping plate 6, and a drive plate 13 that drives the first mounting plate 12 to move. The horizontal motor 10 is installed below the welding table 4. The drive component 11 is fixedly connected to the output shaft of the horizontal motor 10. The drive component 11 is linked to the drive plate 13 through a transmission assembly. The first mounting plate 12 is slidably mounted on one end of the drive plate 13. When the horizontal motor 10 is started, the output shaft of the horizontal motor 10 drives the drive component 11 to rotate. The drive component 11 is driven by a first rotating shaft 14, a first connecting block 15, a connecting column 16, a second connecting block 17, and a second rotating shaft 16. The transmission assembly consisting of 8 components converts rotational motion into linear motion of the drive plate 13. When the drive plate 13, which slides along the sliding groove at the upper end of the welding table 4, moves, it drives the first mounting plate 12 to slide, thereby moving the clamping plate 6 towards the plate material and clamping the plate material. Since the clamping plate 6 is an elastic plate, it will adaptively adjust according to the shape of the plate material during the clamping process. At the same time, the anti-slip rubber 9 increases the friction and prevents the plate material from sliding. The design of the elastic plate and the anti-slip rubber 9 can not only ensure the clamping force of the clamping plate 6 on the plate material, but also avoid damage to the surface of the plate material during the clamping process. It is suitable for ship plates of different shapes and materials. The transmission method of the horizontal drive component is stable and reliable, which can realize the precise movement and clamping of the clamping plate 6, ensure that the plate material is fixed in position during the welding process, and improve the welding accuracy and stability.

[0022] The transmission assembly includes a first rotating shaft 14, a first connecting block 15, a connecting column 16, a second connecting block 17, and a second rotating shaft 18. The lower ends of the driving member 11 are rotatably connected to the first rotating shaft 14 on both sides. The outer walls of the two first rotating shafts 14 are fixedly connected to the first connecting blocks 15. The lower end of the driving plate 13 is rotatably connected to the second rotating shaft 18. The outer wall of the second rotating shaft 18 is fixedly connected to the second connecting block 17. The connecting column 16 connects the first connecting block 15 and the second connecting block 17. Two symmetrically distributed return springs are fixedly connected to one end of the two clamping plates 6. The other ends of the two return springs are fixedly connected to the first mounting plate 12. The transmission assembly adopts a linkage structure, which can efficiently and stably convert the rotational motion of the driving member 11 into the linear motion of the driving plate 13, ensuring the smooth movement of the clamping plates 6.

[0023] The lifting component includes a cylinder 19, a limiting groove 20, and a limiting block 21. The top of each of the two drive plates 13 is equipped with a cylinder 19, and the walls of each of the two drive plates 13 are provided with limiting grooves 20. The limiting block 21 is slidably connected in the limiting groove 20. The upper end of the limiting block 21 is fixedly connected to the output shaft of the cylinder 19, and one side of the limiting block 21 is fixedly connected to the first mounting plate 12. The clamping plate 6 is moved up and down through the first mounting plate 12.

[0024] The dust collection component includes a first dust collection port 22 fixedly installed on the upper ends of two first mounting plates 12, a processing box 23 installed on the lower end of the welding table 4, a second dust collection port 24 located above the welding table 4, a first pipe connecting the first dust collection port 22 and the processing box 23, a first pipe 25 connecting the second dust collection port 24, an adsorption element located inside the processing box 23, and exhaust fans 26 installed on the side walls of the processing box 23. The exhaust fans 26 are positioned lower than the adsorption element. The first pipe 25 is fixedly installed on the wall of the processing box 23. Ventilation outlets 27 are provided on the side walls of the welding table 4, and filters 28 are provided inside the ventilation outlets 27. An anti-clogging mechanism is provided at the upper end of the adsorption element. During the welding process, the pump is started, and the first dust collection port 22 and the second dust collection port 24 are sucked in the welding exhaust gas under the action of suction force. The exhaust gas is transported through the first pipe and the first pipe 25. The exhaust gas is sent to the treatment box 23, where it is adsorbed by the adsorption net 34, and harmful substances are adsorbed. The purified air is then discharged to the outside through the air vents 27 and filter net 28 on both sides of the welding table 4 by the exhaust fan 26. When the adsorption net 34 needs to be cleaned, the second mounting plate 32 is pulled out by the handle, and at the same time, the anti-clogging motor 36 drives the ball screw 37 to rotate, so that the cleaning plate 38 moves up and down in the treatment box 23, and the brush 39 cleans the adsorption net 34. The setting of multiple dust suction ports realizes all-round collection of welding exhaust gas, improving the exhaust gas collection efficiency. The adsorption net 34 in the treatment box 23 can effectively adsorb harmful substances in the exhaust gas, reducing harm to the environment and operators. The anti-clogging mechanism automatically cleans the adsorption net 34, ensuring the continuous and efficient operation of the dust collection component, reducing the frequency of manual cleaning, and reducing equipment maintenance costs.

[0025] The first pipe assembly includes a second pipe 29, a third pipe 30, and a fourth pipe 31. A first suction port 22 is fixedly connected to the second pipe 29. The lower end of the second pipe 29 is connected to the third pipe 30. The end of the third pipe 30 furthest from the second pipe 29 is connected to the fourth pipe 31. One end of the fourth pipe 31 is fixedly installed inside the treatment box 23. The third pipe 30 is a flexible hose. Pumps are installed on both the first pipe 25 and the two second pipes 29. After the pumps are started, they generate suction, causing the welding exhaust gas to sequentially pass through the first suction port 22, the second pipe 29, the third pipe 30, and the fourth pipe 31 into the treatment box 23. Because the third pipe 30 is a flexible hose, it can be freely bent and deformed during the movement of the clamping plate 6 and the plate, without affecting the normal operation of the suction function. The use of a flexible hose increases the flexibility of the suction pipes, allowing them to adapt to the movement of the clamping plate 6 and the plate during the welding process, ensuring the stable operation of the suction system. The reasonable pipe layout and pump settings ensure that the exhaust gas can be smoothly transported to the treatment box 23 for purification, improving suction efficiency and system reliability.

[0026] The adsorption unit includes a second mounting plate 32 slidably connected to the wall of the treatment box 23, two symmetrically distributed openings 33 on the second mounting plate 32, and an adsorption net 34 disposed in the openings 33. One end of the second mounting plate 32 slides outside the treatment box 23 and is fixedly connected to a handle. The adsorption net 34 is fixedly installed inside the second mounting plate 32. The two sides of the second mounting plate 32 are rounded, forming a storage cavity 35 between the second mounting plate 32 and the adsorption net 34. One end of the treatment box 23 is hinged to a door. When the adsorption net 34 needs to be cleaned or replaced, the second mounting plate 32 can be pulled out of the treatment box 23 by pulling the handle. At this time, impurities on the adsorption net 34 can be cleaned, or the adsorption net 34 can be directly replaced. The design of the pull-out second mounting plate 32 makes the cleaning and replacement of the adsorption net 34 simple and convenient, reducing the difficulty of equipment maintenance. The storage cavity 35 can collect impurities that fall during the cleaning process, preventing impurities from scattering inside the treatment box 23 and affecting the normal operation of the equipment.

[0027] The anti-clogging mechanism includes an anti-clogging motor 36, a ball screw 37 fixedly connected to the output shaft of the anti-clogging motor 36, a cleaning plate 38 threadedly connected to the ball screw 37, and a brush 39 fixedly connected to the lower end of the cleaning plate 38. The anti-clogging motor 36 is installed on the inner wall of the processing box 23, and the cleaning plate 38 is slidably connected to the inner wall of one end of the processing box 23. The anti-clogging motor 36 starts at set intervals according to a preset program, and the output shaft of the anti-clogging motor 36 drives the ball screw 37 to rotate. When the ball screw 37 rotates, the cleaning plate 38 moves up and down along the inner wall of the processing box 23 through threaded transmission. The brush 39 at the lower end of the cleaning plate 38 cleans the adsorption net 34 to prevent the adsorption net 34 from clogging. After cleaning, the anti-clogging motor 36 stops running. The anti-clogging mechanism realizes automatic cleaning of the adsorption net 34 without frequent manual intervention, which improves the automation level of equipment operation. Regular cleaning can effectively prevent the adsorption net 34 from clogging, ensure the adsorption efficiency and processing capacity of the dust collection components, extend the service life of the equipment, and reduce manual maintenance costs.

[0028] The moving component includes a base 40 installed at the lower end of the laser welding robot 1 and the Mag welding robot 8 respectively.

The upper ends of the moving wheels are rotatably connected to the base 40. The output shafts of second moving motors 42 are fixedly connected to the center of two moving wheels. The second moving motors 42 are installed on the outer wall plates of the moving wheels. A second rotary motor 43 is installed at one end of the Mag welding robot 8. The output shaft of the second rotary motor 43 is connected to the Mag welding head 44.

[0029] A welding process for high-precision ship welding equipment, the details of which are as follows: S1. First, several component ship plate bodies 5 are placed on the welding table 4. The limiting plate 7 is used to initially position the ship plate bodies 5 to ensure that the ship plate bodies 5 are in the right position. Then, the horizontal motor 10 is started. The horizontal motor 10 drives the drive component 11 to rotate. The drive component 11 drives the drive plate 13 to move through the transmission assembly composed of the first rotating shaft 14, the first connecting block 15, the connecting column 16, the second connecting block 17, and the second rotating shaft 18. The drive plate 13 then drives the first mounting plate 12 to move, so that the clamping plate 6 clamps and fixes the ship plate bodies 5. Since the clamping plate 6 is an elastic plate and has anti-slip rubber 9 on its surface, it can prevent damage and slippage of the components while clamping. Under the pushing force of the clamping plate 6, the side walls of multiple ship plate bodies 5 are pressed together. S2, firstly, the Mag welding robot 8 is moved to a suitable position by the moving component at the lower end of the Mag welding robot 8 to perform Mag welding on the ship plate body 5. Then, the laser welding robot 1 is moved to a suitable position by the moving component, and the laser welding head 3 is driven to weld the upper end face of the ship plate body 5. After the welding is completed, the cylinder 19 is started. The cylinder 19 drives the limit block 21 to slide in the limit groove 20. The clamping plate 6 and the ship plate body 5 are lifted by the first mounting plate 12. At this time, the Mag welding robot 8 and the laser welding robot 1 are in the same manner as above. Under the action of the first rotary motor 2 and the second rotary motor 43, the laser welding head 3 and the Mag welding head 44 on the Mag welding robot 8 rotate 180 degrees to weld the lower end face of multiple ship plate bodies 5. S3. During the entire welding process, the pump is started, and the first suction port 22 and the second suction port 24 suck in the waste gas generated during welding. The waste gas enters the treatment box 23 through the first fitting and the first pipe 25. The waste gas is treated by the adsorption net 34 in the treatment box 23, and harmful substances are adsorbed. The purified air is discharged through the exhaust fan 26 and discharged to the outside through the air diffuser 27 and filter 28 on both sides of the welding table 4. When the adsorption net 34 needs to be cleaned, the second mounting plate 32 is pulled out by the handle to clean the impurities on the adsorption net 34. At the same time, the anti-clogging motor 36 drives the ball screw 37 to rotate, so that the cleaning plate 38 moves up and down in the treatment box 23. The brush 39 cleans the adsorption net 34 to prevent the adsorption net 34 from clogging.

First, place several component ship plate bodies (5) on the welding table (4). Use the limiting plate (7) to initially position the ship plate bodies (5) to ensure that the ship plate bodies (5) are in the right position. Then start the horizontal motor (10). The horizontal motor (10) drives the drive component (11) to rotate. The drive component (11) drives the drive plate (13) to move through the transmission assembly composed of the first rotating shaft (14), the first connecting block (15), the connecting column (16), the second connecting block (17), and the second rotating shaft (18).
