Description

Technical Field

[0001] The present invention relates to the technical field of welding, and specifically to a welding device and method for structural component assembly with a weld quality inspection function. Background Art

[0002] Ship structural components refer to various structural components and parts used in the construction and operation of ships. The design and manufacture of these structural components are crucial for the strength, stability, and safety of ships. Ship structural component welding is an important link in ship manufacturing and repair, involving connecting metal structural components together through welding processes to form a solid whole.

[0003] The quality of welding directly affects the safety and service life of ships. Most of the existing welding processes in shipbuilding usually require manual assistance. This method requires the cooperation of multiple workers, not only consuming a large amount of man-hours and having low efficiency, but also being unable to effectively monitor and inspect the welding at the weld, resulting in the inability to control the welding quality. Summary of the Invention

[0004] The purpose of the present invention is to provide a welding device and method for structural component assembly with a weld quality inspection function to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A welding device for structural component assembly with a weld quality inspection function includes a laser and a thermal imager, and also includes a workbench and a control box. Side plates are installed on both sides of the workbench, and the control box is installed on the workbench. The laser and the thermal imager are both installed on the workbench and electrically connected to the control box. Two driving disks are installed on one side of the side plate. The two driving disks on the same side plate are jointly connected to a driving mechanism. The driving mechanism drives the workbench to move. An electrode plate is provided on the driving mechanism, and the electrode plate is electrically connected to the control box. The electrode plates on the two driving mechanisms cooperate with each other to make current flow through the welding area.

[0006] The workbench is rotatably connected to the side plate. One end of the side plate is connected to the driving mechanism. Axle seats are symmetrically installed above the side plate and above the workbench. An adjusting cylinder is rotatably installed between the axle seats on the side plate and the axle seats on the workbench. The adjusting cylinder is inclined in the vertical direction. The adjusting cylinder is a hydraulic cylinder. The adjusting cylinder adjusts the angle between the side plate and the workbench through the extension and contraction of the cylinder rod, so that the workbench and the side plate can adapt to structural components with an included angle or a bending angle.

[0007] A through slot is provided at the middle position of the workbench. On the workbench, baffles are provided outside the long sides of the through slot. A rotating shaft is rotatably installed at the center position of the through slot. A carrier plate is installed on the rotating shaft. Both sides of the carrier plate are placed on the baffles. Tooth grooves are provided on both sides of the through slot in the middle of the workbench. Both ends of the rotating shaft are inserted into the tooth grooves. Steering gears are installed on the rotating shaft located in the tooth grooves. Guide plates are installed on the workbench on both sides of each tooth groove. Rectangular sliding grooves are provided on the opposite end faces of the guide plates. A rack plate is slidably installed on the two guide plates through the rectangular sliding grooves. Teeth are provided at the lower end of the rack plate. The rack plate is meshed and driven with the steering gear. Lining plates are installed at both ends of the guide plates on the workbench. A rodless cylinder is installed between the two lining plates. The slider of the rodless cylinder is connected to the rack plate. When the baseband is a conveyor belt or a conveyor chain plate connected end to end, when the baseband drives the workbench to move between the structural members to be welded, the laser welds the weld seam driven by the workbench. When the baseband is a conveyor chain plate that is disassembled and not connected end to end, the baseband is fixed on the hoisting truss to serve as a guide rail. At this time, the workbench and the side plate are in a reverse installation state. Therefore, it is necessary to turn the carrier plate 180° on the workbench. The rodless cylinder works, drives the rack plate to move through the slider. During the movement, the rack plate rotates the steering gear. The steering gear turns the carrier plate through the rotating shaft, so that the carrier plate is turned 180°, and the laser still remains in the downward state.

[0008] The number of the thermal imagers is two, and they are located on both sides of the control box. The thermal imagers are distributed before and after the advancing direction of the laser. There is always a thermal imager behind the laser. The thermal imager collects data on the welded position. The control system processes the data fed back by the thermal imager to obtain the welding quality of the welded joint.

[0009] A sleeve is provided on one side of the side plate close to the driving mechanism. The sleeve is sleeved outside the driving disc. One end of the sleeve is rotatably connected to the driving mechanism. The sleeve is rotatably connected to the driving roller. The driving roller is installed on the side plate through the sleeve, so that the driving disc only needs to provide power for the rotation of the driving roller.

[0010] The driving mechanism includes a driving roller axially connected to the driving disc, and a baseband meshed and driven with the two driving rollers. A number of card slots are provided on the driving roller. A number of bearing columns adapted to the card slots are provided on the inner side of the baseband. A rotating groove is provided on the driving roller. One end of the sleeve is rotatably installed in the rotating groove. An annular limiting groove is radially provided in the middle of the driving roller. A middle column is provided in the middle of each bearing column. The width of the middle column is the same as the width of the limiting groove. The middle column and the limiting groove cooperate with each other to prevent the position deviation between the baseband and the driving roller. The driving disc drives the driving roller to rotate. The two driving rollers cooperate with each other to make the baseband operate, and drive the workbench to move along the weld seam. The laser welds the weld seam.

[0011] The side plate has a "T" - shaped structure. A ferrule is installed below the middle of the side plate on the side away from the workbench. A clamping groove is provided at the lower end of the ferrule. At the lower sides of both ends of the clamping groove, there are right - angled trapezoidal electrode posts. At the lower sides of both ends of each bearing post, there are right - angled trapezoidal notches. The electrode posts are located within the notches. A power - transmission wire electrically connected to the control system is arranged inside the ferrule. Copper sheets are provided on the inclined surface of one of the electrode posts and on the vertical surfaces of the two electrode posts. The copper sheets are electrically connected to the power - transmission wire. The copper sheets on the two vertical surfaces are respectively connected to the positive and negative poles of the power supply. The copper sheet on the inclined surface is in contact with the copper sheets on the vertical surfaces. Metal contacts are provided on the inclined surface of one of the notches and on the vertical surfaces of the two notches. The metal contacts are in sliding contact with the copper sheets. The electrode plate is installed on the baseband. The electrode plate is electrically connected to the metal contact on the inclined surface. When the baseband moves on the structural member, the control system in the control box connects the copper sheets to the circuit, and then through the metal contacts, the electromagnetic member and the electrode plate are connected to the circuit. The electromagnetic member is energized to generate a magnetic field and magnetically attract the structural member, preventing the baseband from deviating in direction when it moves on the structural member. The electrode plates on the two basebands cooperate with each other to make the current flow through the welding joint of the structural member. The control system calculates the resistance value of the welding joint according to Ohm's law and verifies the welding quality of the welding joint again through the resistance value. When the electrode plate and the electromagnetic member within the coverage of the ferrule are energized and the driving roller rotates to drive the baseband to operate, the side plate also has a relative position with the baseband, causing the bearing posts within the coverage of the ferrule to move out of the coverage range, making the electrode plate and the electromagnetic member de - energize naturally without additional control by the control system. The electrode plate and the electromagnetic member corresponding to the bearing posts newly entering the coverage of the ferrule will automatically be connected to the circuit and operate.

[0012] Inside the baseband, an electromagnetic member is installed corresponding to each bearing post. The electromagnetic member is electrically connected to the metal contacts on the two vertical surfaces. The electromagnetic member is energized to generate a magnetic field. The electromagnetic member consists of an excitation coil and an iron core. The excitation coil is connected to the metal contact.

[0013] The baseband is a conveyor belt or a detachable conveyor chain plate. The material of the baseband is an insulating material.

[0014] A welding method for assembling structural members with a weld quality inspection function uses a welding device for assembling structural members with a weld quality inspection function. The method includes the following steps:

[0015] S1. Confirm the position of the laser according to the welding position;

[0016] S2. The laser performs welding operations on the weld;

[0017] S3. The thermal imager collects data on the heat at the welding point and feeds it back to the control system. The control system calculates the welding quality of the weld;

[0018] S4. When the baseband travels on the structural member to be welded, current flows through the welding area. Using Ohm's law, the control system calculates the resistance and further determines the welding quality of the weld seam.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The thermal imager performs thermal imaging detection on the welding area and feeds back to the control system in the control box. The control system processes the data fed back by the thermal imager to obtain the welding quality of the weld seam. During the movement of the workbench, the two electrode plates cooperate with each other to make current flow through the welding area. The control system calculates the resistance value of the welding area according to Ohm's law and verifies the welding quality of the welding area again through the resistance value. Through the double quality inspections of the thermal imager and the resistance value, the quality inspection of the weld seam is ensured to be effective and accurate.

[0021] 2. The baseband can be a conveyor belt or a conveyor chain plate. The baseband drives the workbench to travel and weld on the structural member. Or the conveyor chain plate can be disassembled and inverted on the truss to act as a guide rail. The bushing acts as a slider and the side plate and the workbench are hoisted on the truss. The driving roller travels on the baseband, enabling the laser to perform welding operations on the structural member under the hoisted condition. Through the setting of the baseband, the usage range of the welding device is expanded. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] A welding method for structural component assembly with weld quality inspection function uses a welding device for structural component assembly with weld quality inspection function. The method includes the following steps:

[0040] S1. Confirm the position of the laser according to the welding position;

[0041] S2. The laser performs welding operations on the weld seam;

[0042] S3. The thermal imager collects data on the heat at the welding point and feeds it back to the control system. The control system calculates the welding quality of the weld seam.

[0043] S4. When the baseband travels on the structural member to be welded, current flows through the welding point. Using Ohm's law, the control system calculates the resistance and further obtains the welding quality of the weld seam.

[0044] The working principle of the present invention:

[0045] When welding a structural member, place this welding device on the structural member. When the included angle between the two components forming the structural member is 90°, the adjusting cylinder 4 adjusts the included angle between the side plate 2 and the workbench 1 by the contraction of the cylinder rod, so that the workbench 1 and the side plate 2 can adapt to the structural member with a 90° included angle, and the workbench 1 is in an inclined state of 45°. When the included angle between the two components forming the structural member is 180°, the workbench 1 and the side plate 2 are in a parallel state.

[0046] When the baseband 7 is a conveyor belt or a conveyor chain plate connected end to end, the driving disc 3 drives the driving roller 8 to rotate, and the baseband 7 runs. When the baseband 7 drives the workbench 1 to travel between the structural members to be welded, the laser welds the weld seam under the drive of the workbench 1.

[0047] When the baseband 7 travels on the structural member, the control system in the control box 5 connects the copper sheet to the circuit, and then through the metal contact, the electromagnetic member 21 and the electrode plate 18 are connected to the circuit. The electromagnetic member 21 is energized to generate a magnetic field and magnetically attract the structural member, preventing the baseband 7 from deviating in direction when traveling on the structural member.

[0048] When the electrode plate 18 and the electromagnetic member 21 within the coverage of the ferrule 9 are energized and the driving roller 8 rotates to drive the baseband 7 to run, a relative position is generated between the side plate 2 and the baseband 7, causing the bearing column 10 within the coverage of the ferrule 9 to move out of the coverage, so that the electrode plate 18 and the electromagnetic member 21 are naturally powered off, without the need for additional control by the control system. The electrode plate 18 and the electromagnetic member 21 corresponding to the bearing column 10 newly entering the coverage of the ferrule 9 will automatically be connected to the circuit and operate.

[0049] The electrode plates 18 on the two basebands 7 cooperate with each other to make the current flow through the welding point of the structural member. The control system calculates the resistance value at the welding point according to Ohm's law and verifies the welding quality at the welding point again through the resistance value.

[0050] According to the welding position of the structural member, the baseband 7 can be disassembled. When the baseband 7 is disassembled into conveying chain plates that are not connected at the head and tail, the baseband 7 is fixed on a suspended or overhead truss, so that the baseband 7 is inverted in the air and acts as a guide rail. The ferrule 9 is installed on the bearing column 10 through the electrode post and the notch 20. The ferrule 9 acts as a slider and drives the side plate 2 to move on the baseband 7. The overall length of the baseband 7 can be increased by itself according to the working requirements.

[0051] When the baseband 7 is inverted, since the workbench 1 and the side plate 2 are also in an inverted state, it is necessary to first turn the carrier plate 12 by 180° on the workbench 1 before the baseband 7 is inverted. The rodless cylinder 16 works under the control of the control system, drives the rack plate 14 to move through the slider. During the movement, the rack plate 14 rotates the steering gear 15, and the steering gear 15 turns the carrier plate 12 through the rotating shaft, so that the carrier plate 12 completes a 180° turn, keeping the laser still in the downward state. The laser welds the weld seam.

[0052] The thermal imagers 6 are distributed in front of and behind the advancing direction of the laser. There is always one thermal imager 6 behind the laser. After the laser welds the weld seam, the thermal imager 6 collects data on the welded position, and the control system processes the data fed back by the thermal imager 6 to obtain the welding quality of the welded part.

[0053] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
