Description

Technical Field

[0001] The present invention relates to the technical field of intelligent welding, and in particular to a vehicle-mounted intelligent welding robot. Background Art

[0002] The vehicle-mounted intelligent welding robot, also commonly known as the orbital welding robot, is a type of welding robot that is widely used in automobile production. The orbital welding robot is a robot that moves on a fixed track and performs welding operations. It is usually composed of a fixed track and a mobile welding trolley. The track is installed near the welding workpiece, and the welding gun is fixed on the welding trolley to achieve automatic welding of the welding workpiece. The robot drives the welding gun to move on the track through the control system and performs welding operations at the predetermined position. The control system can realize autonomous control and motion control of the robot, and control the movement direction, speed, time and other parameters of the welding robot through a remote control or computer program.

[0003] During the use of welding robots, the frequency of maintenance is relatively frequent due to the need for regular and uninterrupted use.

[0015] Compared with the prior art, the present invention provides a vehicle-mounted intelligent welding robot, which has the following beneficial effects:

[0016] 1. The invention realizes the rapid disassembly and assembly of the welding robot body and the rail pulley through the design of the connection component.

[0017] 2. The one-piece casting structure of the connection platform in the present invention is formed by integral casting, with a dense internal structure and no weak links such as welding seams, so it has high strength and rigidity. This enables the No. 1 connection platform to withstand large loads and impact forces, ensuring the stability and safety of the welding robot body during operation. During the casting process, the one-piece casting structure can form a relatively uniform internal structure and relatively precise external dimensions due to the flow and solidification of the molten metal.

[0018] 3. The present invention combines the movement of the rail trolley and the acceleration of the booster plate, and the heat dissipation system realizes rapid heat dissipation of the drive motor inside the welding robot body. This can not only extend the service life of the drive motor, but also improve the overall performance and stability of the welding robot. Structures such as the heat dissipation cavity and the heat dissipation pipe are integrated in the connection component, and no additional heat dissipation equipment or space is required. This not only saves costs, but also makes the structure of the welding robot more compact and integrated. Since the heat dissipation system utilizes the movement of the rail trolley and the natural flow of air, it does not require additional energy input. This adaptive design enables the welding robot to maintain good heat dissipation in different working environments and conditions;

[0019] 4. The maintenance of the heat dissipation system in the present invention is relatively simple. Since it is integrated in the connection assembly, during the daily maintenance of the welding robot, the status of structures such as the heat dissipation cavity and the heat dissipation pipe can be checked to ensure their normal operation.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments 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.

[0030] Example: Figures 1 to 3As shown, an embodiment of the present invention provides a vehicle-mounted intelligent welding robot, including a moving guide rail 1, a track pulley 4 is provided on the top of the moving guide rail 1, a welding robot body is provided on the top of the track pulley 4, the welding robot body includes a fixed platform 6 fixedly connected to the top of the connecting component 5, the top of the fixed platform 6 is fixedly connected to a first drive motor 601, one side of the top of the fixed platform 6 is rotatably connected to a connecting arm 7, one side of the bottom of the connecting arm 7 is fixedly connected to a second drive motor 701, one side of the top of the connecting arm 7 is fixedly connected to a third drive motor 702, one side of the top of the connecting arm 7 is rotatably connected to a connecting forearm 8, and the connecting arm 8 is connected to the connecting arm 8. One end of the small arm 8 is fixedly connected to the fourth drive motor 801, and the other end of the small arm 8 is rotatably connected to the mounting frame 9. The interior of the mounting frame 9 is fixedly connected to the fifth drive motor 901, and the output shaft of the fifth drive motor 901 is fixedly connected to the welding head 10. The operator starts the control system of the welding robot and inputs the initial command through the remote control or computer program. After the control system receives the command, the main body of the welding robot moves the welding head 10 to the top of the workpiece to be welded through the coordinated movement of the connecting arm 7, the small arm 8 and the mounting frame 9. The control system controls the fixture or suction cup and other mechanisms under the welding head 10. Clamp the workpiece to be welded to ensure the stability of the workpiece during the welding process. The operator inputs the welding path and process parameters into the control system according to the shape of the workpiece and the welding requirements. The control system controls the welding robot body to perform welding operations according to the predetermined path and speed according to the input instructions. During the welding process, the No. 1 drive motor 601, the No. 2 drive motor 701, the No. 3 drive motor 702, the No. 4 drive motor 801 and the No. 5 drive motor 901 respectively drive the movement of the fixed platform 6, the connecting arm 7, the connecting arm 8 and the mounting frame 9 to achieve precise positioning and movement of the welding head 10 in three-dimensional space. The welding machine The human body is equipped with a variety of sensors for real-time monitoring of information such as current, voltage, temperature, weld shape and workpiece position during the welding process. The control system adjusts the welding parameters and the movement trajectory of the welding head 10 in real time according to the information fed back by the sensors to ensure the stability and consistency of the welding quality. When the welding operation is completed, the control system controls the clamp or suction cup under the welding head 10 to release the workpiece. The welding robot body moves the welding head 10 to a safe position through the coordinated movement of the connecting arm 7, the connecting arm 8 and the mounting frame 9. The operator turns off the control system of the welding robot, completes this operation and prepares for the next operation.

[0031] In this embodiment, if Figures 1 to 3The transmission assembly shown is used to drive the welding robot body to move horizontally. The transmission assembly is connected to the moving guide rail 1. The transmission assembly includes a moving motor 2 fixedly connected to one end of the moving guide rail 1. A driving screw 3 is fixedly connected to the output shaft of the moving motor 2. The driving screw 3 is located at the center of the moving guide rail 1. Guide grooves 102 are provided on both sides of the top of the moving guide rail 1. Slide grooves 101 are provided on both sides of the moving guide rail 1. A threaded block 403 threadedly connected to the outside of the driving screw 3 is provided at the center of the bottom of the track pulley 4. Side plates are provided on both sides of the bottom of the track pulley 4. Transmission rollers 401 are fixedly connected on opposite surfaces. The outer ring of the transmission roller 401 contacts the inner wall of the slide groove 101. Two sliding plates 402 are screwed to the bottom of the track pulley 4. The two sliding plates 402 are respectively slidably connected to the inside of the two guide grooves 102. When the welding robot body needs to be moved, the moving motor 2 is started first. After receiving the start signal, the mobile motor 2 starts to run and generate power. The output shaft of the mobile motor 2 is fixedly connected to the driving screw 3, so the power generated by the mobile motor 2 is transmitted to the driving screw 3 through the output shaft. After receiving the power, the driving screw 3 starts to rotate. The center of the bottom of the track pulley 4 is provided with a thread block 403 that is threadedly connected to the outside of the driving screw 3. When the driving screw 3 rotates, the thread block 403 is pushed by the thread and starts to make linear motion outside the driving screw 3. This movement process is achieved through the helix angle of the thread, that is, the rotational motion of the driving screw 3 is converted into the linear motion of the thread block 403. In order to ensure the stability and accuracy of the track pulley 4 during the movement process, guide grooves 102 are provided on both sides of the top of the mobile guide rail 1. Two sliding plates 402 are screwed to the bottom of the track pulley 4, and the two sliding plates 402 are respectively slidably connected to the inside of the two guide grooves 102. Through the cooperation of the guide groove 102 and the sliding plate 402, the lateral displacement of the rail trolley 4 during the movement process can be limited to ensure that it can only move linearly along the length direction of the moving guide rail 1. At the same time, the sliding grooves 101 are also opened on both sides of the moving guide rail 1, and the side plates at the bottom of the rail trolley 4 are provided with transmission rollers 401. The outer ring of the transmission roller 401 contacts the inner wall of the sliding groove 101. This design further increases the stability and smoothness of the rail trolley 4 during the movement process. With the continuous rotation of the driving screw 3, the threaded block 403 drives the rail trolley 4 to move linearly along the length direction of the moving guide rail 1. The operator can control the speed and direction of the moving motor 2 through the control system, so as to achieve precise control of the moving speed and direction of the rail trolley 4. When the rail trolley 4 moves to the specified position, the control system sends a stop signal to the moving motor 2. After receiving the stop signal, the moving motor 2 stops running, and the rail trolley 4 also stops moving. At this point, the main body of the welding robot has been accurately positioned at the designated position, ready for the next welding operation. The transmission component adopts a threaded transmission method, which has the advantages of high transmission efficiency, smooth movement, and accurate positioning.By precisely controlling the speed and direction of the mobile motor 2, the moving speed and direction of the rail trolley 4 can be precisely controlled, thereby meeting the requirements of welding operation for accuracy and stability. The structural design of the transmission component is compact and reasonable, and the internal space of the mobile guide rail 1 is fully utilized. The driving and positioning of the rail trolley 4 is achieved through the cooperation of the mobile motor 2 fixedly connected to one end of the mobile guide rail 1 and the driving screw 3. This design not only reduces the overall size and weight of the equipment, but also improves the reliability and service life of the equipment.

[0032] In this embodiment, if Figures 1 to 7The connecting assembly 5 shown is used for the rapid disassembly, assembly and maintenance of the welding robot body. The connecting assembly 5 is connected to the rail pulley 4. The connecting assembly 5 includes a No. 1 connecting platform 501 bolted to the center of the top of the rail pulley 4. A center frame 504 is provided at the center of the top of the No. 1 connecting platform 501. The top of the No. 1 connecting platform 501 is located on both sides of the center frame 504 and is fixedly connected with connecting members 503. Both connecting members 503 are arc-shaped. A docking point is provided at the top of the connecting member 503. A deformation cavity 5031 is provided inside the docking point. A deformation point is provided at the bottom of the connecting member 503. A C-shaped weakening groove 5032 is provided on one side of the deformation point. The No. 1 connecting platform 501 is an integrally cast structure. The connecting assembly 5 also includes a No. 2 connecting platform 502 screwed to the bottom of the fixed platform 6. The bottom of the No. 2 connecting platform 502 is provided with a connecting groove 5 021, a square groove 5022 matched with the center frame 504 is provided at the center of the connecting groove 5021, a circular groove 5023 matched with the two connecting members 503 is provided inside the connecting groove 5021, and reset members 505 are fixedly connected on the sides of the center frame 504 facing the connecting members 503, and a bending portion is provided at the center of the reset member 505, and a movable groove is provided at the bottom of both sides of the center frame 504, and two sliding members 507 are slidably connected inside each movable groove, and a telescopic member 506 is fixedly connected on the outside of each sliding member 507, and the other end of the telescopic member 506 is connected to the connecting member 503, and a telescopic cavity for the telescopic member 506 to be telescopic is provided inside the connecting member 503. When the welding robot body needs to be installed on the rail pulley 4, first ensure that the various components of the connecting assembly 5 are in the initial state. The No. 1 connection platform 501 has been firmly connected to the top center of the rail pulley 4 by bolts, and the No. 2 connection platform 502 is ready to be connected to the bottom of the fixed platform 6. The No. 2 connection platform 502 is aligned with the No. 1 connection platform 501, so that the connection groove 5021 corresponds to the center frame 504 and the connection piece 503. In the initial docking process, the square groove 5022 is adapted to the center frame 504, and the circular groove 5023 is adapted to the two connection pieces 503, ensuring that the two can be docked smoothly. As the No. 2 connection platform 502 is further pressed down, the bottom deformation of the connection piece 503 begins to deform under the action of the weakening groove 5032, and the deformation cavity 5031 provides space for this deformation. At the same time, the telescopic member 506 slides along the movable groove driven by the sliding member 507 and gradually extends until the top docking point of the connecting member 503 is tightly fitted with the inner wall of the No. 2 connecting platform 502. When the connecting member 503 is completely deformed and clamped, the bent portion of the reset member 505 returns to its original state under the action of elasticity, pushing the sliding member 507 and the telescopic member 506 to move further into the interior of the connecting member 503, thereby increasing the friction between the connecting member 503 and the No. 2 connecting platform 502, and achieving a more secure locking. At this time, the welding robot body has been successfully installed on the rail pulley 4 through the firm connection between the fixed platform 6 and the No. 2 connecting platform 502.If disassembly is required, the welding robot body can be easily removed from the rail trolley 4 by simply reversing the above process. The connection assembly 5 realizes the rapid disassembly and assembly of the welding robot body by means of the cleverly designed deformation part and telescopic part 506. The operator can easily complete the installation and disassembly work without using complicated tools or performing cumbersome operations, which greatly improves the work efficiency. The No. 1 connection platform 501 is an integral casting structure with high strength and rigidity. At the same time, the deformation part of the connection member 503 can be deformed and clamped when under pressure through the design of the weakened groove 5032, which increases the stability and reliability of the connection. The coordinated use of the reset member 505 and the telescopic member 506 further enhances the firmness of the connection. The design of the connection assembly 5 has high adaptability and can adapt to welding robot bodies of different models and specifications. By adjusting the size and shape of the connection member 503 and the telescopic member 506, the needs of different customers can be met. The various components of the connection assembly 5 are tightly connected and well matched, and have high reliability and stability. At the same time, the disassembly and installation of each component are also relatively simple and convenient, which is convenient for the operator to carry out daily maintenance and overhaul work.

[0033] In this embodiment, if Figures 1 to 8As shown, a heat dissipation cavity 5041 is provided inside the center frame 504, and wide-mouth surfaces 5042 are provided at both ends of the heat dissipation cavity 5041, and the two wide-mouth surfaces 5042 are both facing the transmission direction of the transmission component. The inside of the heat dissipation cavity 5041 is symmetrically fixedly connected with boost plates 5043, and each boost plate 5043 is provided with a connecting hole 5044. The inside of the No. 1 connecting platform 501 is fixedly connected with a connecting pipe 12, and the output end of the connecting pipe 12 is located at the center of the heat dissipation cavity 5041, and the input end of the connecting pipe 12 is located outside the No. 1 connecting platform 501. A heat dissipation pipe 11 is fixedly connected to one side of the welding robot body, and a plurality of connecting pipes are provided on the outside of the heat dissipation pipe 11, each of which is fixedly connected to the protective cover of each drive motor respectively, and the other end of the heat dissipation pipe 11 is fixedly connected to the input end of the connecting pipe 12. When the welding robot is performing welding operations, the drive motor and other internal electronic components will generate a large amount of heat. In order to effectively discharge the heat, the heat dissipation pipe 11 is fixedly connected to one side of the welding robot body, and a plurality of connecting pipes are arranged on the outside thereof, and these connecting pipes are fixedly connected to the protective cover of each driving motor respectively. In this way, the heat generated by the driving motor can be collected into the heat dissipation pipe 11 through the connecting pipe, and the collected heat flows with the air inside the heat dissipation pipe 11. The other end of the heat dissipation pipe 11 is fixedly connected to the input end of the connecting pipe 12, so that the heat is transferred to the connecting pipe 12. The connecting pipe 12 passes through the interior of the No. 1 connecting platform 501, and its output end is located at the center of the heat dissipation cavity 5041. When the heat enters the heat dissipation cavity 5041, it encounters the boost plate 5043. The boost plate 5043 is symmetrically fixedly connected to the interior of the heat dissipation cavity 5041, and a connecting hole 5044 is opened inside it. These connecting holes 5044 allow the fluid to flow freely between the boost plates 5043, while increasing the residence time and flow path of the fluid in the heat dissipation cavity 5041, thereby improving the heat dissipation efficiency. Wide-mouthed surfaces 5042 are provided at both ends of the heat dissipation cavity 5041, and both wide-mouthed surfaces 5042 face the transmission direction of the transmission assembly. Such a design helps to discharge the heat in the heat dissipation cavity 5041 to the environment more quickly. As the fluid continues to flow, the heat is exchanged with the surrounding environment through the wide-mouthed surfaces 5042 and is eventually discharged into the air. By designing structures such as the heat dissipation cavity 5041, the boost plates 5043, and the connecting holes 5044, the flow path and residence time of the fluid in the heat dissipation system are effectively increased, thereby improving the heat dissipation efficiency. This helps to reduce the temperature of the welding robot body and the drive motor and extend their service life. The heat dissipation system is cleverly integrated inside the center frame 504, without the need for additional installation space. This compact design not only saves space, but also helps to reduce the weight and cost of the cooling system. Since the main components of the cooling system are concentrated inside the center frame 504 and the first connecting platform 501, maintenance is relatively simple and convenient.Operators can easily check, clean and replace components in the heat dissipation system. The design of the heat dissipation system has high adaptability and can adapt to welding robot bodies of different models and specifications. By adjusting the size and shape of the heat dissipation pipe 11, the connecting pipe and the connecting pipe 12, the needs of different customers can be met. An effective heat dissipation system can reduce the temperature of the welding robot body and the drive motor, reduce the risk of fire or failure caused by overheating, and thus improve the safety of the entire welding operation.

[0034] The working principle provided by the present invention is that when the welding robot body needs to be installed on the rail pulley 4, first ensure that the various components of the connecting assembly 5 are in the initial state. The No. 1 connecting platform 501 has been firmly connected to the top center of the rail pulley 4 by bolts, and the No. 2 connecting platform 502 is ready to be connected to the bottom of the fixed platform 6. The No. 2 connecting platform 502 is aligned with the No. 1 connecting platform 501, so that the connecting groove 5021 corresponds to the center frame 504 and the connecting member 503. In the process of preliminary docking, the square groove 5022 is adapted to the center frame 504, and the circular groove 5023 is adapted to the two connecting members 503, ensuring that the two can be docked smoothly. With the further downward pressure of the No. 2 connecting platform 502, the bottom deformation of the connecting member 503 begins to deform under the action of the weakening groove 5032, and the deformation cavity 5031 provides space for this deformation. At the same time, the telescopic member 506 slides along the moving groove driven by the sliding member 507, and gradually extends until the top docking point of the connecting member 503 is tightly fitted with the inner wall of the second connecting platform 502. When the connecting member 503 is completely deformed and clamped, the bent portion of the reset member 505 returns to its original state under the action of elasticity, pushing the sliding member 507 and the telescopic member 506 to move further into the connecting member 503, thereby increasing the friction between the connecting member 503 and the second connecting platform 502, and achieving a more secure locking. At this time, the welding robot body has been successfully installed on the rail pulley 4 through the secure connection between the fixed platform 6 and the second connecting platform 502. When the welding robot body needs to be moved, the mobile motor 2 is first started. After receiving the start signal, the mobile motor 2 starts to run and generate power. The output shaft of the mobile motor 2 is fixedly connected to the drive screw 3, so the power generated by the mobile motor 2 is transmitted to the drive screw 3 through the output shaft. The driving screw 3 starts to rotate after receiving power, and a threaded block 403 is provided at the center of the bottom of the rail trolley 4, which is threadedly connected to the outside of the driving screw 3. When the driving screw 3 rotates, the threaded block 403 is pushed by the thread and starts to move linearly outside the driving screw 3.This movement process is achieved through the helix angle of the thread, that is, the rotational movement of the driving screw 3 is converted into the linear movement of the thread block 403. In order to ensure the stability and accuracy of the rail pulley 4 during movement, the operator starts the control system of the welding robot and inputs the initial command through the remote control or computer program. After the control system receives the command, the welding robot body moves the welding head 10 to the top of the workpiece to be welded through the coordinated movement of the connecting arm 7, the connecting arm 8 and the mounting frame 9. Through the control system, the clamp or suction cup and other mechanisms under the welding head 10 clamp the workpiece to be welded to ensure the stability of the workpiece during the welding process. The operator inputs the welding path and process parameters into the control system according to the shape of the workpiece and the welding requirements. The control system controls the welding robot body to perform welding operations according to the predetermined path and speed according to the input command. During the welding process, the No. 1 drive motor 601, the No. 2 drive motor 701 and the No. 3 drive motor 70 2. The fourth drive motor 801 and the fifth drive motor 901 drive the movement of the fixed platform 6, the connecting arm 7, the connecting arm 8 and the mounting frame 9 respectively, so as to realize the precise positioning and movement of the welding head 10 in three-dimensional space. The main body of the welding robot is equipped with a variety of sensors for real-time monitoring of the current, voltage, temperature, weld shape and workpiece position during the welding process. The control system adjusts the welding parameters and the movement trajectory of the welding head 10 in real time according to the information fed back by the sensors to ensure the stability and consistency of the welding quality. When the welding operation is completed, the control system controls the fixture or suction cup under the welding head 10 to release the workpiece. The main body of the welding robot moves the welding head 10 to a safe position through the coordinated movement of the connecting arm 7, the connecting arm 8 and the mounting frame 9. The operator turns off the control system of the welding robot, completes this operation and prepares for the next operation. When the welding robot is performing welding operations, the driving motor and other internal electronic components will generate a large amount of heat. In order to effectively discharge this heat, the heat dissipation pipe 11 is fixedly connected to one side of the main body of the welding robot, and a plurality of connecting pipes are arranged on the outside thereof, which are fixedly connected to the protective cover of each driving motor. In this way, the heat generated by the drive motor can be collected into the heat dissipation pipe 11 through the connecting pipe, and the collected heat flows with the air inside the heat dissipation pipe 11. The other end of the heat dissipation pipe 11 is fixedly connected to the input end of the connecting pipe 12, so the heat is transferred to the connecting pipe 12. The connecting pipe 12 passes through the interior of the first connecting platform 501, and its output end is located at the center of the heat dissipation cavity 5041. When the heat enters the heat dissipation cavity 5041, it encounters the boost plate 5043. The boost plate 5043 is symmetrically fixedly connected to the interior of the heat dissipation cavity 5041, and a connecting hole 5044 is opened inside it.These connecting holes 5044 allow the fluid to flow freely between the supercharging plates 5043, while increasing the residence time and flow path of the fluid in the heat dissipation cavity 5041, thereby improving the heat dissipation efficiency. Both ends of the heat dissipation cavity 5041 are provided with wide-mouthed surfaces 5042, and both wide-mouthed surfaces 5042 face the transmission direction of the transmission assembly. Such a design helps to discharge the heat in the heat dissipation cavity 5041 to the environment more quickly. As the fluid continues to flow, the heat is exchanged with the surrounding environment through the wide-mouthed surface 5042 and is eventually discharged into the air. By designing structures such as the heat dissipation cavity 5041, the supercharging plates 5043 and the connecting holes 5044, the flow path and residence time of the fluid in the heat dissipation system are effectively increased, thereby improving the heat dissipation efficiency. This helps to reduce the temperature of the welding robot body and the drive motor and extend their service life. The heat dissipation system is cleverly integrated inside the center frame 504, without the need for additional installation space. This compact design not only saves space, but also helps to reduce the weight and cost of the heat dissipation system.
