Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to welding equipment for a bionic robot. Background Art

[0002] With the rapid development of artificial intelligence and automation technology, bionic robots, as a high-tech equipment that simulates biological motion and behavior characteristics, are widely used in the fields of medical care, manufacturing, services, national defense, etc. Bionic robots have complex structures and are usually composed of multiple parts with irregular shapes and various sizes. They need to be accurately connected together through welding and other methods to ensure the realization of their functions and the strength and reliability of the overall structure. Welding, as a key processing technology, plays a vital role in the performance and service life of bionic robots.

[0003] In the traditional manufacturing process of bionic robots, welding processes usually rely on manual operation or semi-automatic equipment, which has many problems. First, the shapes of bionic robot parts are diverse and complex, and the welding positions are usually located in inaccessible areas, which makes manual operation difficult and requires extremely high technical skills of welders. Secondly, due to the subjectivity and fatigue factors of manual operation, the quality and safety of welding are difficult to guarantee, especially when it comes to the connection of key parts, welding deviations or insufficient strength are prone to occur. In addition, traditional welding equipment has low flexibility during the processing process and is difficult to adapt to the needs of small batches and multiple varieties in the production process of bionic robots. With the development of bionic robot technology, higher requirements are put forward for welding processes, including high precision, high efficiency, automation and flexibility.

[0004] At present, some automated welding equipment has been applied in the industrial field, such as the combination of robotic arms and laser welding, but there are still many technical difficulties when it is applied to the production of bionic robots. First, the complex geometric shapes of bionic robot parts require welding equipment to have multi-axis motion and complex trajectory planning capabilities, and existing equipment lacks adaptability and flexibility. Secondly, the accuracy and efficiency of traditional welding equipment in grasping, positioning and conveying workpieces are difficult to meet the high-standard production requirements of bionic robots. Especially in the welding of miniaturized and lightweight bionic robot parts, higher requirements are placed on the precision control of the equipment and the protection of the workpiece. In addition, in continuous welding and multi-station operations, how to achieve stable workpiece transportation and automated cycle operations is also an important bottleneck of the existing technology. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a welding device for a bionic robot, which solves the problems of insufficient precision, low degree of automation and poor safety in the welding process of complex parts of the bionic robot.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a welding device for a bionic robot, comprising a workbench, a welding delivery assembly is arranged on the top of the workbench, a plurality of rotating rods are rotatably arranged on the top of the workbench, surrounding rods are fixedly connected on both sides of the top of the workbench, a second pulley is rotatably connected to the top of the surrounding rod, a threaded rod is threadedly connected to the inner wall of the second pulley, a vertical ring is rotatably connected to the outer wall of the threaded rod, a spring is arranged at the bottom of the vertical ring, the top of the threaded rod is in contact with the welding delivery assembly, and is used to release pressure on the threaded rod to drive the second pulley to transmit belt transmission to the first pulley fixed on the top of the rotating rod, thereby driving the material receiving and feeding assembly to move, and a suction cup assembly is arranged on the top of the workbench.

[0007] Preferably, the vertical ring is slidably connected to the inner wall of the surrounding rod, the vertical ring is limited by a through groove provided on the outer wall of the surrounding rod, and one end of the spring is fixedly arranged on the inner wall of the surrounding rod.

[0008] Preferably, the welding delivery assembly includes a connecting block, and a plurality of the connecting blocks are fixedly connected to the top of the workbench. One side of the connecting block is rotatably connected to an electric telescopic rod for driving the fixedly connected force rod and synchronization rod to perform axial movement on the inner wall of the positioning block. The adjacent sides of the two synchronization rods are rotatably connected to a displacement plate. One side of the workbench is provided with a plurality of mounting plates, the inner wall of the mounting plate is provided with a bearing, and a force rod is fixedly connected to one side.

[0009] Preferably, the force applying rod is slidably connected to the top of the threaded rod.

[0010] Preferably, limit rods are provided on both sides of the displacement plate, and the limit rods are slidably connected to the outer wall of the force rod. When the positions of the force rod and the synchronization rod are changed, the axial rotation direction of the displacement plate is changed by the sliding length of the limit rods on the outer wall of the force rod.

[0011] Preferably, the material receiving and feeding assembly includes a first bevel gear, which is fixedly connected to the bottom of the rotating rod, the inner wall of the workbench is rotatably connected to a plurality of reciprocating screws, the inner wall of the workbench is rotatably connected to a transmission rod, the outer wall of the reciprocating screw is threadedly connected to a threaded sleeve, the top of the threaded sleeve is fixedly connected to a slide, the outer wall of the reciprocating screw is fixedly connected to a worm gear, both ends of the transmission rod are fixedly connected to second bevel gears, and the outer wall of the transmission rod is fixedly connected to a plurality of worms.

[0012] Preferably, the worm wheel is meshingly connected to the worm, and the second bevel gear is meshingly connected to the first bevel gear.

[0013] Preferably, the slide plate is slidably connected to the top of the workbench through a groove passing through the top of the workbench.

[0014] Preferably, the suction cup assembly includes a limit plate, which is fixedly connected to one side of the workbench, and a gas tank is installed on the inner wall of the limit plate. The output end of the gas tank is connected to an air pipe, and one end of the air pipe is connected to a plurality of vacuum discs installed at the bottom of the displacement plate.

[0015] Preferably, a laser welding machine body is installed on the rear side of the workbench, and a welding cover is installed on the top of the workbench.

[0016] Working principle: When using this device for bionic robot structural welding, the staff first turns on the electric telescopic rod, and completes the workpiece grabbing through the vacuum adsorption force provided by the gas tank and the gas pipe. The vacuum plate is fixed under the displacement plate. Then, the staff starts the electric telescopic rod, drives the force rod and the synchronization rod to drive the displacement plate to rotate axially around the positioning block. During the rotation process, through the action of the force rod, the displacement plate can be changed from the original vertical downward state to the state facing the side of the laser welding machine body, so as to facilitate the flipping of the workpiece and adjust its welding position for processing operations.

[0017] After welding is completed, as the displacement plate returns to its initial position, the force rod vertically squeezes the threaded rod downward, and drives the rotating rod connected to the second pulley to rotate through the threaded connection, thereby transmitting power to the feeding assembly. During this power transmission process, the adsorption functions of multiple vacuum plates are turned on and off according to the alternating rules through PLC control. The welded workpiece will be released from the vacuum plate and fall to the inner wall of the slide, while the unprocessed workpiece will be adsorbed and fixed to enter the next round of welding process.

[0018] As the force rod reduces the pressure on the threaded rod, the spring resets and applies an upward thrust to the threaded rod through the vertical ring. The threaded rod rises and reversely drives the second pulley to rotate, realizing the reverse power transmission of the feeding assembly. At this time, the slide is moved to the side close to the operator, making it easier for the operator to remove the welded workpiece and load the unwelded workpiece to enter the next welding cycle. Through this operation process, the automated cycle of welding and feeding is completed, ensuring the efficiency and accuracy of the welding operation.

[0019] The present invention provides a welding device for a bionic robot, which has the following beneficial effects: 1. The present invention realizes automatic conveying of welding workpieces and smooth transfer of workpieces after welding through the feeding and receiving assembly. The multi-stage transmission structure of the first bevel gear, the second bevel gear, the reciprocating screw, the slide plate and other components ensures the high efficiency and stability of feeding and returning materials, reduces manual intervention in the welding process, improves processing safety and is suitable for continuous welding operations.

[0020] 2. The present invention can realize precise rotation around the positioning block through the displacement plate under the cooperation of the force rod, the synchronization rod and the force rod, and adjust the axial movement direction of the displacement plate through the limit rod. This flexible posture adjustment function makes the processing of complex welding positions of the bionic robot structure more convenient, and improves the coverage and operation accuracy of welding.

[0021] 3. The present invention ensures the precise alignment of the welding position through the cooperation between the laser welding machine body and the welding delivery assembly. The coordinated movement of the displacement plate and the slide plate greatly reduces the welding error, and the stable delivery of the workpiece significantly improves the welding efficiency, which can meet the needs of mass production of bionic robot components.

DETAILED DESCRIPTION

[0024] 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.

[0025] Please see attached Figure 3 -Attached Figure 5The embodiment of the present invention provides a welding device for a bionic robot, including a workbench 1, a welding feeding assembly is arranged on the top of the workbench 1, a plurality of rotating rods 16 are rotatably arranged on the top of the workbench 1, surrounding rods 18 are fixedly connected to both sides of the top of the workbench 1, a second pulley 20 is rotatably connected to the top of the surrounding rod 18, a threaded rod 19 is threadedly connected to the inner wall of the second pulley 20, a vertical ring 21 is rotatably connected to the outer wall of the threaded rod 19, a spring 22 is arranged at the bottom of the vertical ring 21, the top of the threaded rod 19 is in contact with the welding feeding assembly, and is used to release pressure on the threaded rod 19 to drive the second pulley 20 to drive with the first pulley 17 fixed on the top of the rotating rod 16, thereby driving the material receiving and feeding assembly to move, and a suction cup assembly is arranged on the top of the workbench 1.

[0026] The vertical ring 21 is slidably connected to the inner wall of the surrounding rod 18, and the vertical ring 21 is limited by a through groove provided on the outer wall of the surrounding rod 18. One end of the spring 22 is fixedly arranged on the inner wall of the surrounding rod 18. A laser welding machine body 3 is installed at the rear side of the workbench 1, and a welding cover 2 is installed on the top of the workbench 1.

[0027] Specifically, the top of the workbench 1 is designed as a multifunctional operating platform, and a welding feeding assembly is installed on the top of the workbench 1 to realize the automatic feeding of the workpiece and the connection of the welding process. The top of the workbench 1 realizes power transmission through a plurality of rotating rods 16 connected in rotation. The top of the rotating rod 16 is fixedly installed with a first pulley 17, which forms a power transmission path with the second pulley 20 through a belt transmission, and further drives the movement of the feeding assembly, thereby realizing the automatic transmission of the workpiece.

[0028] The top of the workbench 1 is fixedly connected with an enclosing rod 18 on both sides, and the top thereof is connected to the second pulley 20 through a rotating mechanism. The inner wall of the second pulley 20 cooperates with the threaded rod 19 through a threaded connection. After receiving the force from the welding delivery assembly, the threaded rod 19 can release pressure downward and drive the second pulley 20 to rotate to achieve power transmission. At the same time, the outer wall of the threaded rod 19 is rotatably connected to the vertical ring 21, and the vertical ring 21 provides an upward reset force through a spring 22 arranged at its bottom. One end of the spring 22 is fixed to the inner wall of the enclosing rod 18, and the vertical ring 21 is limited by a through groove arranged on the outer wall of the enclosing rod 18 to ensure its stable movement and effectively avoid deviation. The top of the threaded rod 19 directly contacts the welding delivery assembly, and adjusts its positional relationship with the workpiece by moving up and down to ensure that the workpiece can accurately enter the welding area.

[0029] A suction cup assembly is also provided on the top of the workbench 1 to fix the unwelded workpiece by adsorption force to prevent it from deflecting or sliding during the transfer process, thus ensuring the accuracy of the welding position. When the entire device is in operation, the laser welding machine body 3 installed on the rear side of the workbench 1 is responsible for the welding operation, and its welding area is covered by the welding cover 2 installed on the top to play a protective role and prevent external interference. The welding cover 2 can also prevent the leakage of light and heat during the welding process, thereby improving safety.

[0030] The coordinated use of the above structure can realize automatic transportation of welding workpieces and smooth transfer of workpieces after welding, reduce manual intervention in the welding process, improve processing safety and be suitable for continuous welding operations.

[0031] Please refer to the attached Figure 1 -Attached Figure 3 The welding delivery assembly includes a connecting block 6, and a plurality of connecting blocks 6 are fixedly connected to the top of the workbench 1. One side of the connecting block 6 is rotatably connected to an electric telescopic rod 7, which is used to drive the fixedly connected force rod 8 and the synchronous rod 9 to perform axial movement on the inner wall of the positioning block 4. The adjacent sides of the two synchronous rods 9 are rotatably connected to a displacement plate 10. One side of the workbench 1 is provided with a plurality of mounting plates 5, and the inner wall of the mounting plate 5 is provided with a bearing, and a force rod 15 is fixedly connected to one side. The force rod 15 is slidably connected to the top of the threaded rod 19.

[0032] Limit rods are arranged on both sides of the displacement plate 10, and the limit rods are slidably connected to the outer wall of the force rod 15. When the positions of the force rod 8 and the synchronization rod 9 are changed, the axial rotation direction of the displacement plate 10 is changed by the sliding length of the limit rods on the outer wall of the force rod 15.

[0033] Specifically, the welding delivery assembly includes a plurality of connection blocks 6, which are fixedly connected to the top of the workbench 1 to play a role of connection and support. One side of the connection block 6 is rotatably connected to the electric telescopic rod 7, and the driving function of the electric telescopic rod 7 is used to drive the connected force rod 8 and synchronization rod 9 to perform axial movement on the inner wall of the positioning block 4. Through the telescopic action of the electric telescopic rod 7, the precise movement of the synchronization rod 9 can be achieved.

[0034] The synchronization rod 9 is rotationally connected to the displacement plate 10 through its adjacent side, and the two synchronization rods 9 act on the displacement plate 10 at the same time, causing it to rotate stably around the positioning block 4. The displacement plate 10 is designed as a core component for dynamic adjustment, and limit rods are arranged on both sides thereof. These limit rods are slidably connected to the outer wall of the force rod 15, and can limit the movement range of the displacement plate 10 when the outer wall of the force rod 15 slides, thereby maintaining the stability of its rotation direction. When the relative position of the force rod 8 and the synchronization rod 9 changes, the limit rod slides along the outer wall of the force rod 15, and the change in the sliding length will directly change the axial rotation direction of the displacement plate 10, thereby realizing the flipping or posture adjustment of the workpiece.

[0035] A plurality of mounting plates 5 are provided on one side of the workbench 1, and bearings are provided on the inner wall of the mounting plate 5 to ensure smooth sliding connection of the force rod 15, reduce friction, and improve mechanical life and operating accuracy. At the same time, the force rod 15 is fixedly connected to the top of the threaded rod 19 and interacts with the second pulley 20 through a threaded connection. When the force rod 15 comes into contact, the threaded rod 19 will rotate accordingly, thereby driving the second pulley 20 to complete the rotation. The sliding of the limit rod and the rotation of the force rod 15 act together on the movement path of the displacement plate 10, so that it can be adjusted according to the established movement trajectory before and after welding.

[0036] Please refer to the attached Figure 4 The material receiving and feeding assembly includes a first bevel gear 23, which is fixedly connected to the bottom of the rotating rod 16. The inner wall of the workbench 1 is rotatably connected to a plurality of reciprocating screws 24. The inner wall of the workbench 1 is rotatably connected to a transmission rod 27. The outer wall of the reciprocating screw 24 is threadedly connected to a threaded sleeve 25. The top of the threaded sleeve 25 is fixedly connected to a slide plate 30. The outer wall of the reciprocating screw 24 is fixedly connected to a worm gear 26. Both ends of the transmission rod 27 are fixedly connected to second bevel gears 28. The outer wall of the transmission rod 27 is fixedly connected to a plurality of worms 29.

[0037] The worm wheel 26 is meshed with the worm 29, and the second bevel gear 28 is meshed with the first bevel gear 23. The slide plate 30 is slidably connected to the top of the workbench 1 through the through groove at the top of the workbench 1.

[0038] Specifically, the material receiving and feeding assembly includes a first bevel gear 23, which is fixedly connected to the bottom of the rotating rod 16 and provides power input through the rotation of the rotating rod 16. A plurality of reciprocating screws 24 are installed on the inner wall of the workbench 1, and these reciprocating screws 24 transmit power to the connected threaded sleeve 25 through rotational motion. The outer wall of the threaded sleeve 25 is threadedly connected to the reciprocating screw 24, and the top of the threaded sleeve 25 is fixedly connected to the slide plate 30 to realize the linear conveyance of the workpiece. The slide plate 30 passes through the through groove at the top of the workbench 1 and is slidably connected to the top of the workbench 1 to ensure that the movement direction of the slide plate 30 is limited and the accuracy of its linear motion is maintained.

[0039] The outer wall of the reciprocating screw 24 is fixedly mounted with a worm wheel 26, and power transmission is achieved through the meshing connection between the worm wheel 26 and the worm 29. The worm 29 is evenly distributed and fixed on the outer wall of the transmission rod 27, and the two ends of the transmission rod 27 are fixedly connected with the second bevel gear 28. The second bevel gear 28 meshes with the first bevel gear 23, and the rotation of the first bevel gear 23 provides power for the entire material receiving and feeding assembly. The transmission relationship between the worm wheel 26 and the worm 29 converts power from rotational motion to spiral motion, thereby driving the threaded sleeve 25 to move along the axis of the reciprocating screw 24, driving the slide plate 30 to slide smoothly on the top of the workbench 1.

[0040] The design of the slide plate 30 ensures that the workpiece remains stable during the conveying process. Its sliding motion is constrained by the limit of the through groove, which effectively prevents the deviation caused by inertia or vibration. The transmission rod 27 forms a meshing transmission network with the worm 29 on its outer wall and multiple worm wheels 26 to ensure the synchronization of the movement of the slide plate 30 and the uniformity of power distribution. The entire assembly efficiently transmits power to the slide plate 30 through the cooperation of a multi-stage transmission system such as bevel gears, worm wheels 26, worms 29 and lead screws, achieving precise and smooth feeding operations, improving processing efficiency, and meeting the needs of mass production of bionic robot components.

[0041] Please see attached Figure 1 , Attachment Figure 3 The suction cup assembly includes a limit plate 11, which is fixedly connected to one side of the workbench 1. A gas tank 12 is installed on the inner wall of the limit plate 11. The output end of the gas tank 12 is connected to an air pipe 13, and one end of the air pipe 13 is connected to a plurality of vacuum discs 14 installed at the bottom of the displacement plate 10.

[0042] Specifically, the suction cup assembly includes a limit plate 11, which is fixedly connected to one side of the workbench 1 to play a supporting and limiting role. A gas tank 12 is installed on the inner wall of the limit plate 11. The gas tank 12 serves as a gas source and provides the power required for vacuum adsorption through the compressed gas stored therein.

[0043] The output end of the gas tank 12 is connected to the external pneumatic circuit through the air pipe 13, and one end of the air pipe 13 is connected to multiple vacuum plates 14 installed at the bottom of the displacement plate 10. The air pipe 13 distributes the gas provided by the gas tank 12 to each vacuum plate 14 evenly through reasonable arrangement, thereby forming a stable negative pressure adsorption force. The vacuum plate 14 is responsible for contacting with the workpiece and fixing the workpiece by negative pressure adsorption. The connection between the air pipe 13 and the gas tank 12 is tight to ensure the stability of the gas flow and ensure that the vacuum plate 14 can always maintain sufficient adsorption force under load.

[0044] During operation, the gas tank 12 controls the adsorption and release of the vacuum plate 14 through the gas pipe 13. When the gas tank 12 provides negative pressure, the vacuum plate 14 is tightly attached to the surface of the workpiece, forming a stable adsorption to prevent the workpiece from shifting during transportation or processing. When the workpiece needs to be released, the gas tank 12 stops supplying negative pressure or provides positive pressure, thereby releasing the adsorption between the vacuum plate 14 and the workpiece, making it easier to unload or transfer the workpiece.

[0045] Through the support and fixation of the gas tank 12 and the gas pipe 13 by the limit plate 11, and the integrated design of the vacuum plate 14 and the displacement plate 10, the suction cup assembly can work in coordination with other components of the overall device to achieve full-process automated operation from grasping to releasing the workpiece.

[0046] 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.
