Description

Technical Field

[0001] The invention relates to the technical field of riveting and welding equipment, and in particular to an intelligent riveting and welding workstation and a control method. Background Art

[0002] In modern industrial manufacturing, the welding of H-beams and ribs is an indispensable process in many fields such as construction, bridges, and machinery manufacturing. Traditional welding operations mainly rely on manual operations, which have problems such as high labor intensity, low production efficiency, and unstable welding quality. Especially when dealing with large H-beams and complex rib plate structures, the limitations of manual welding are particularly obvious, and it is difficult to meet the production needs of high precision and high efficiency.

[0003] With the continuous development of automation technology, robotic arms and automated workstations are increasingly used in industrial production. However, in view of the specific needs of H-beam and ribbed plate welding operations, existing automation solutions still have many shortcomings. For example, some automated workstations can only achieve a single welding function and cannot complete the integrated operation of clamping, placing and welding the ribbed plate, resulting in cumbersome production processes and low efficiency. At the same time, the existing technology lacks sufficient flexibility and adaptability when processing H-beams and ribbed plates of different specifications and quantities, and cannot meet diverse production needs.

[0004] In addition, in traditional welding operations, the movement and positioning accuracy of the robot arm are often affected by many factors, such as the wear of the guide rails and the error of the drive system, resulting in unstable welding quality. The placement and positioning of the rib plate also rely on manual or simple mechanical devices, making it difficult to achieve high-precision and high-efficiency automated operations. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent riveting and welding workstation and control method to solve the problems in the prior art, realize the high integration and automation of rib plate placement and welding operations, ensure the high-precision positioning of the robot arm during movement and the stable adsorption and release of the rib plate, and improve the versatility and applicability of the equipment.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] An intelligent riveting and welding workstation comprises: a main frame, the main frame is connected with a first guide rail, a left guide rail and a right guide rail extending along the X direction, wherein the first guide rail is connected to the upper end surface of the main frame, and the left guide rail and the right guide rail are respectively connected to the two sides of the main frame; a first mechanical arm is slidably connected to the first guide rail through a first slide, and the end of the first mechanical arm is connected to a rib plate clamp for clamping and placing the rib plate; a left mechanical arm is slidably connected to the left guide rail through a second slide, and the end of the left mechanical arm is connected to a welding gun for welding the rib plate; a right mechanical arm is slidably connected to the right guide rail through a third slide, and the end of the right mechanical arm is connected to a welding gun for welding the rib plate; a left support tooling and a right support tooling are respectively arranged on the Y sides of the main frame, and are used to support a first H-shaped steel and a second H-shaped steel extending along the X direction.

[0015] S4. When the rib plate is placed on the first H-shaped steel, the left robotic arm moves to the planned position and spot welds the first rib plate with a welding gun. After completion, the first robotic arm releases the rib plate, and the left robotic arm performs full welding on the rib plate with a welding gun.

[0016] When the rib plate is placed on the second H-beam, the right robotic arm moves to the planned position and spot welds the rib plate with a welding gun.

[0023] S2.2, the electromagnetic chuck is powered off and demagnetized, the rib plate automatically falls down under the action of gravity, and automatically slides along the stopper on the universal ball support surface of the alignment table to achieve the positioning and placement of the rib plate;

[0024] S2.3. The electromagnetic suction cup is powered on and magnetized again, generating magnetic force again to re-attract the rib plate and accurately grasp the rib plate.

[0025] Step S3 specifically includes:

[0026] S3.1. The first robot arm transports the rib plate to above the predetermined welding position of the first H-beam or the second H-beam;

[0027] S3.2. The first mechanical arm expands the two side wing plates of the first H-beam or the second H-beam to a predetermined width through the expansion mechanism;

[0028] S3.3. The electromagnetic chuck moves downward to send the rib plate to the predetermined welding position and maintains adsorption to facilitate subsequent spot welding positioning operations.

[0029] The control method further comprises step S6:

[0030] After completing the welding of the ribs on one side of the first H-beam and the second H-beam, flip the steel 180° manually or automatically, restart the platform with one button, and perform riveting and welding on the other side of the steel until the welding of the ribs on both sides is completed.

[0031] The control method further comprises step S7:

[0032] After all the ribs are welded, the left and right robotic arms move to the gun cleaning station to clean, cut the wire, and spray oil on the welding guns to prepare for the next welding operation.

DETAILED DESCRIPTION

[0045] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] In the first aspect of the present application, an intelligent riveting and welding workstation is proposed, comprising a main frame 1, a first robotic arm 5, a left robotic arm 7, a right robotic arm 9, a left supporting tooling 11 and a right supporting tooling 12.

[0050] See also Figures 1 to 5 , each component will be described in detail below with reference to the accompanying drawings.

[0051] The main frame 1 is used as the supporting base of the entire workstation, and a first guide rail 2 extending along the X direction is installed on its upper end surface for guiding the movement of the first mechanical arm 5. At the same time, a left guide rail 3 and a right guide rail 4 are installed on both sides of the main frame 1, respectively, for the sliding connection of the left mechanical arm 7 and the right mechanical arm 9, so that the left mechanical arm 7 and the right mechanical arm 9 can weld the first H-beam and the second H-beam simultaneously or independently, thereby improving the work efficiency.

[0052] The first mechanical arm 5 is slidably connected to the first guide rail 2 through the first slide 6, so as to realize free movement in the X direction. The end of the first mechanical arm 5 is connected with a rib plate clamp, which is responsible for clamping and placing the rib plate to ensure that the rib plate can be accurately positioned at the designated position of the H-beam.

[0053] The left and right mechanical arms, the left and right mechanical arms 7 and 9 are slidably connected to the left and right guide rails 3 and 4 through the second slide 8 and the third slide 10, respectively. The ends of the two mechanical arms are equipped with welding guns for welding the ribs placed in the H-beam. In order to improve welding efficiency and flexibility, multiple left and right mechanical arms 7 and 9 can be configured, each of which works independently and moves along the guide rails through their own slides to achieve multi-point simultaneous welding, which significantly shortens the operation cycle.

[0054] The left support fixture 11 and the right support fixture 12 are respectively arranged on both sides of the main frame 1 in the Y direction, and are used to support the first H-shaped steel and the second H-shaped steel extending in the X direction. The support fixture is also equipped with a clamping mechanism for clamping and positioning the H-shaped steel to ensure that the H-shaped steel remains stable during the welding process and avoid welding deviation caused by external forces.

[0055] In order to ensure the smooth and precise movement of the robot arm on the guide rail, a rack and pinion drive mode can be adopted; specifically, a first rack extending along the X direction is fixed to the upper end surface of the main frame 1, and a second rack and a third rack extending along the X direction are also provided on the left guide rail 3 and the right guide rail 4, respectively. The first slide 6, the second slide 8 and the third slide 10 are respectively equipped with a first motor 13, a second motor 14 and a third motor 15, each motor drives the gear connected thereto through a reducer, and the gear meshes with the corresponding rack, thereby realizing the precise movement of the slide on the guide rail. The rack and pinion transmission mode has the advantages of fast response speed and smooth operation, ensuring the high-precision positioning of the robot arm during operation.

[0056] The rib plate clamp is a key component for clamping and placing the rib plate. The rib plate clamp is mainly composed of a clamp mounting seat 16, a support mechanism 17 and an electromagnetic suction cup 18. The clamp mounting seat 16 serves as the support base of the entire clamp and is connected to the end of the first mechanical arm 5 to ensure the stability of the clamp during operation. The main function of the support mechanism 17 is to use mechanical force to open the two side wing plates of the H-shaped steel before placing the rib plate to create space for the smooth placement of the rib plate. An adjustable support arm is provided inside the support mechanism 17, which can be adjusted according to the specific size of the H-shaped steel to ensure the expansion effect. The electromagnetic suction cup 18 is responsible for the absorption and placement of the rib plate. When absorbing the rib plate, the electromagnetic suction cup 18 is energized to generate a magnetic field, and the rib plate is firmly adsorbed by the magnetic suction force; when placing the rib plate, the electromagnetic suction cup 18 is powered off, the magnetic suction force disappears, and the rib plate falls between the two side wing plates of the H-shaped steel under the action of gravity. The expansion mechanism 17 can be implemented using the prior art provided in the patent publication number CN117340532A.

[0057] In order to improve the welding efficiency, multiple left-side robotic arms 7 and right-side robotic arms 9 can be configured. A welding gun is installed at the end of each robotic arm. Each robotic arm is equipped with an independent drive system and control system, which can independently complete the welding task according to the preset program. The collaborative operation of multiple robotic arms not only shortens the welding time of a single H-beam, but also improves the operational flexibility of the entire workstation, so that the workstation can adapt to the welding needs of H-beams and ribs of different specifications and quantities.

[0058] In summary, by integrating automatic robotic arms, guide rail systems and drive mechanisms, this intelligent riveting and welding workstation achieves a high degree of integration and automation of rib plate placement and welding operations; the collaborative operation of multiple robotic arms not only shortens the welding time of a single H-beam, but also greatly improves the operating efficiency of the overall workstation, significantly shortening the production cycle.

[0059] The use of gear rack transmission ensures the accuracy of rib plate placement and high-precision positioning of the robot arm during movement. The precise transmission ratio of the gear rack ensures the stable operation of the robot arm; the use of electromagnetic suction cup technology can stably absorb and release the rib plate, ensuring the precise alignment of the rib plate during placement and welding.

[0060] The workstation can be equipped with multiple robotic arms according to production needs, and the supporting tooling is adjustable, which can adapt to the welding operations of H-shaped steels and rib plates of different specifications and quantities, allowing the workstation to easily meet the needs of different production scenarios and improve the versatility and applicability of the equipment.

[0061] The operator only needs to import the model into the control system or input instructions to realize the automation of the entire welding process. This highly automated operation method greatly reduces the intensity of manual labor and improves the safety and comfort of production.

[0062] A second aspect of the present application provides a control method for an intelligent riveting and welding workstation, comprising the following steps:

[0063] S1. The program sets the size parameters of the first H-beam and the second H-beam, and the welding positions of each rib on the first H-beam and the second H-beam;

[0064] S2, the first robot arm 5 picks up a rib plate from the material frame, and moves along the planned path to the top of the alignment table to automatically align the rib plate to achieve precise positioning;

[0065] S3, the first robot arm 5 places the rib plate at a predetermined welding position of the first H-beam or the second H-beam according to the planned path, and maintains a clamping state;

[0066] S4. When the rib plate is placed on the first H-shaped steel, the left robotic arm 7 moves to the planned position and spot welds the first rib plate with a welding gun. After completion, the first robotic arm 5 releases the rib plate, and the left robotic arm 7 performs full welding on the rib plate with a welding gun.

[0067] When the rib plate is placed on the second H-shaped steel, the right robotic arm 9 moves to the planned position and spot welds the rib plate with a welding gun. After completion, the first robotic arm 5 releases the rib plate, and the right robotic arm 9 performs full welding on the rib plate with a welding gun.

[0068] S5. Repeat steps S2 to S4 until the welding of all the set ribs is completed.

[0069] Step S1 specifically includes:

[0070] S1.1. Import the data of the first H-beam model and the second H-beam model into the control system, and the control system automatically identifies the length, width, height, web thickness, flange thickness of the first H-beam and the second H-beam, as well as the length, width, thickness and position information of the rib plate;

[0071] S1.2. The control system automatically plans the movement paths of the first robotic arm 5, the left robotic arm 7, and the right robotic arm 9 according to the parameters of the steel section and the rib plate.

[0072] Step S2 specifically includes:

[0073] S2.1, the first robot arm 5 sucks a rib plate from the material frame through the electromagnetic chuck 18, and moves to the designated position above the alignment table according to the planned path;

[0074] S2.2, the electromagnetic chuck 18 is powered off and demagnetized, and the rib plate automatically falls down under the action of gravity, and automatically slides along the stopper on the universal ball support surface of the alignment table to achieve the positioning and placement of the rib plate;

[0075] S2.3, the electromagnetic suction cup 18 is powered on and magnetized again, and the magnetic force is regenerated to re-adsorb the rib plate and accurately grasp the rib plate.

[0076] Step S3 specifically includes:

[0077] S3.1. The first robot arm 5 transports the rib plate to above the predetermined welding position of the first H-beam or the second H-beam;

[0078] S3.2, the first mechanical arm 5 expands the two side wing plates of the first H-beam or the second H-beam to a predetermined width (the width of the web) through the expansion mechanism 17;

[0079] S3.3, the electromagnetic chuck 18 moves downward to send the rib plate to the predetermined welding position and maintains adsorption to facilitate subsequent spot welding positioning operations.

[0080] The control method further comprises step S6:

[0081] After completing the welding of the ribs on one side of the first H-beam and the second H-beam, flip the steel 180° manually or automatically, restart the platform with one button, and perform riveting and welding on the other side of the steel until the welding of the ribs on both sides is completed.

[0082] Step S6 specifically includes:

[0083] S6.1. After completing the welding of the rib plate on one side, the control system controls the flipping mechanism to flip the H-beam 180°. The flipping mechanism can be driven by hydraulic or electric means to ensure a smooth and accurate flipping process.

[0084] S6.2. After the H-beam is flipped into place, the control system restarts the platform with one button. At this time, the workstation will automatically identify the current state of the H-beam and re-plan the movement path and welding operation of the robot arm.

[0085] S6.3. After restarting, the workstation will perform riveting and welding operations on the other side of the H-beam according to the preset procedures and paths. The welding quality and consistency of the rib plate on the other side are ensured through the coordinated operation and precise positioning of the left and right robotic arms.

[0086] The control method further comprises step S7:

[0087] After all the ribs are welded, the left robot arm 7 and the right robot arm 9 move to the gun cleaning station to clean, cut the wire, and spray oil on the welding guns to prepare for the next welding operation.

[0088] Step S7 specifically includes:

[0089] S7.1, the left robotic arm 7 and the right robotic arm 9 respectively move to the position of the welding gun cleaning station, which cleans the welding gun with high-pressure gas or cleaning fluid to remove impurities and residues generated during the welding process.

[0090] S7.2. After cleaning is completed, the robot arm cuts the welding wire through the wire cutting mechanism on the gun cleaning station.

[0091] S7.3. Finally, the gun cleaning station sprays oil on the welding gun through the oil spray device to form a protective film on the surface of the welding gun to prevent spatter generated during welding from adhering to the welding gun and affecting the welding quality and the service life of the welding gun.

[0092] The following takes the control method of an intelligent riveting and welding workstation as an example to explain its operation steps and processes in detail.

[0093] Take the example of riveting 7 ribs on one side of a steel section, which are numbered from the front of the first robot arm to the back, and are divided into Z series Z1 to Z7 and Y series Y1 to Y7. Robot arm I is responsible for Z1 to Z4, robot arm II is responsible for Z5 to Z7, robot arm III is responsible for Y1 to Y4, and robot arm IV is responsible for Y5 to Y7. Among them, robot arm I and robot arm II are two left robot arms, and robot arm III and robot arm IV are two right robot arms.

[0094] First cycle:

[0095] The first robot grabs and aligns the 1st to 4th rib plates in turn, and places them at positions Z1, Z5, Y1, and Y5 respectively. After each rib plate is placed, the corresponding welding robot arms I, II, III, and IV first perform spot welding, and then the electromagnetic chuck is demagnetized, and the first robot arm prepares the next rib plate. At the same time, the welding robot arm that has completed spot welding performs full welding, including both sides of the rib plate.

[0096] Second to third round:

[0097] Similar to the first round, but the rib placement is changed to Z2, Z6, Y2, Y6 for the second round and Z3, Z7, Y3, Y7 for the second round.

[0098] In the third round, the simultaneous grasping, alignment and welding processes remain unchanged.

[0099] Fourth cycle:

[0100] The first robot grabs and aligns the 13th rib plate and places it at Z4, and the first robot performs spot welding and full welding. Then, the 14th rib plate is grabbed and placed at Y4, and the third robot completes spot welding and full welding. After that, the first robot returns to the "zero point".

[0101] After completing the riveting and welding of all ribs on one side, the steel section is rotated 180° by the turning device so that the same riveting and welding operation can be performed on the other side.

[0102] After flipping, restart the platform with one button and repeat the above cycle steps until all the ribs on both sides of the steel section are welded.

[0103] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
