Description

Technical Field

[0001] This invention relates to the field of robotics, specifically to an industrial robot with a collision-resistant chassis structure. Background Technology

[0002] With the continuous acceleration of industrial automation, industrial robots are widely used in various production scenarios as key equipment to improve production efficiency and ensure product quality. However, during the movement of robots, they may collide with surrounding equipment, workpieces or other robots. Existing industrial robot collision avoidance structures are mostly simple rigid protection or single-direction buffers, which cannot effectively disperse and absorb energy during collisions. This leads to damage to core robot components such as the robotic arm drive system and control system, affecting normal operation and increasing maintenance costs and downtime. Meanwhile, traditional robot chassis structures are mostly integrated structures, lacking coordination between components. When a component malfunctions, the disassembly and replacement process is extremely cumbersome, requiring a lot of time and manpower, seriously affecting production progress and increasing maintenance costs. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: an industrial robot with a collision-resistant chassis structure, comprising: The robot comprises a base housing and a detachable cover plate mounted on the bottom of the base housing. A robotic arm is mounted in the middle of the top of the cover plate, and an actuator is fixedly mounted at the end of the robotic arm. The robotic arm performs various actions to move the actuator to a designated position and complete industrial operations. A gimbal is mounted on one side of the top of the cover plate, and a camera is mounted on the top of the gimbal. The gimbal allows the camera to be flexibly adjusted to achieve all-round monitoring of the working environment. A receiving hole is opened on the side of the base housing, and an arc-shaped slot block is fixedly mounted on the bottom of the inner cavity of the base housing. A caster wheel is mounted on the bottom of the base housing, which enables the robot to move in different working scenarios and reach the designated working position. A fixing mechanism, which is detachably mounted on the top of the arc-shaped slot block; A buffer mechanism is installed at the edge of the inner cavity of the base housing, and the buffer mechanism is engaged and adapted with the fixing mechanism. The anti-collision mechanism is installed on the buffer mechanism. When the robot is impacted, the external force contacts the anti-collision mechanism, causing it to move on the buffer mechanism. The anti-collision mechanism can absorb part of the impact energy. When the anti-collision mechanism moves, the buffer mechanism rotates and works with the fixed mechanism to buffer the impact. The anti-collision mechanism includes an anti-collision cylinder, an annular guide groove is formed in the middle of the outer surface of the anti-collision cylinder, an annular groove is formed inside the annular guide groove, a slider is slidably installed inside the annular groove, a roller is rotatably installed on the outer surface of the slider, the roller is set inside the buffer mechanism, and an arc spring is installed inside the annular groove. The two ends of the arc spring are respectively connected to the two sides of the slider, and the middle of the arc spring is fixedly installed on the inner wall of the annular groove.

[0004] Preferably, the number of receiving holes is six, and the six receiving holes are evenly distributed along the axis of the base housing. The anti-collision mechanism is disposed inside the receiving holes, and the anti-collision mechanism can provide all-round anti-collision protection for the robot.

[0005] Preferably, the number of the arc-shaped slot blocks is six, and the six arc-shaped slot blocks are evenly distributed along the axis of the base housing. The top of the fixing mechanism is detachably equipped with a hexagonal fixing cover and a hexagonal fixing frame. The hexagonal fixing cover and the hexagonal fixing frame work together to reinforce the fixing mechanism, prevent the fixing mechanism from loosening during robot operation, ensure the stability of the fixing structure, and thus ensure the normal operation of other robot components.

[0006] Preferably, the fixing mechanism includes an arc-shaped fixing plate, which can be detachably installed inside the arc-shaped slot block. The top two ends of the arc-shaped fixing plate are respectively provided with a first mounting hole and a second mounting hole. An mounting groove is provided on the surface of the arc-shaped fixing plate, and a snap-fit ​​hole is provided at the top and bottom of the inner wall of the mounting groove.

[0007] Preferably, the hexagonal fixing cover is detachably installed inside the first mounting hole by bolts, the hexagonal fixing frame is detachably installed inside the second mounting hole by bolts, and the hexagonal fixing cover is located on the inner side of the hexagonal fixing frame.

[0008] Preferably, the buffer mechanism includes a fixed rod, which is fixedly installed at the edge of the inner cavity of the base housing. A rotating arc plate is rotatably installed on the outer surface of the fixed rod, and a guide block is fixedly installed on the inner curved surface of the rotating arc plate. The guide block is located inside the annular guide groove, and a sliding groove is formed on the surface of the guide block. The roller is located inside the sliding groove. When the robot is impacted, the external force first contacts the anti-collision cylinder. At this time, the roller rolls in the sliding groove, and the anti-collision cylinder rolls on the inner curved surface of the rotating arc plate under the combined action of the annular guide groove and the guide block. At this time, the slider slides in the annular groove, and the arc spring absorbs deformation.

[0009] Preferably, a buffer spring is fixedly installed on the side of the outer curved surface of the rotating arc plate away from the fixed rod. The buffer spring is located on the outer curved surface of the arc plate. A snap-fit ​​component is fixedly installed on the other end of the buffer spring. The snap-fit ​​component is detachably installed inside the mounting groove. When the anti-collision cylinder rolls on the inner curved surface of the rotating arc plate, the rotating arc plate rotates around the fixed rod, and the buffer spring is compressed to absorb the impact.

[0010] Preferably, the snap-fit ​​component includes a snap-fit ​​block, the top and bottom of which are provided with receiving grooves. A return spring is fixedly installed inside the receiving groove, and a snap-fit ​​strip is fixedly installed at the other end of the return spring. The snap-fit ​​strip is slidably installed inside the receiving groove. The snap-fit ​​component is detachably installed inside the mounting groove, thereby connecting the buffer mechanism and the fixing mechanism so that the two can work together to complete the buffering task.

[0011] Preferably, the card block is slidably installed inside the mounting groove, and the card strip is engaged and adapted with the card hole. The detachable installation of the buffer mechanism and the fixing mechanism facilitates the maintenance of the components.

[0012] Preferably, the arc-shaped slot block is coaxially arranged with the fixed rod, and the inner curved surface of the rotating arc plate is pressed and matched with the inner curved surface of the arc fixed plate. When the rotating arc plate rotates around the fixed rod, the inner curved surface of the arc fixed plate has a guiding effect, which enhances stability.

[0013] This invention provides an industrial robot with a collision-resistant chassis structure. It offers the following advantages: I. This industrial robot with an anti-collision chassis structure has six receiving holes evenly distributed along the axis of the base shell through the setting of the anti-collision mechanism. Each receiving hole is equipped with a set of anti-collision mechanisms, and the arc-shaped slot block, fixing mechanism and buffer mechanism are all one-to-one with the receiving hole to form an anti-collision structure around the base shell. When the robot is hit by an impact from any direction, the anti-collision cylinder in the corresponding receiving hole first comes into contact with the external force. The anti-collision cylinder rolls along the inner curved surface of the rotating arc plate under the cooperation of the annular guide groove and the guide block of the buffer mechanism. At the same time, the slider slides in the annular groove, compressing the arc spring to deform and absorb part of the energy, completing the initial buffering, effectively dispersing and absorbing the impact force, and preventing the impact force from being directly transmitted to the core components.

[0014] Second, this industrial robot with an anti-collision chassis structure, through the setting of the fixing mechanism, when the fixing mechanism needs maintenance, only needs to unscrew the bolts to remove the hexagonal fixing cover and hexagonal fixing frame, then take the arc-shaped fixing plate out of the arc-shaped slot block, press the locking strip to compress the reset spring and retract it into the receiving groove, and the locking block can be taken out from the mounting groove, separating the buffer mechanism and the fixing mechanism. The detachable design does not require the entire robot to be disassembled. Maintenance personnel can disassemble the faulty parts in a targeted manner, which greatly shortens the maintenance time and reduces the maintenance difficulty.

[0015] Third, this industrial robot with an anti-collision chassis structure, through the cooperation of a rotating arc plate and an arc-shaped fixed plate, ensures that the fixed mechanism and the buffer mechanism are evenly stressed during robot operation by the coaxial design of the arc-shaped slot block and the fixed rod, avoiding structural displacement caused by eccentricity. When the robotic arm vibrates during operation, the hexagonal fixed cover and hexagonal fixed frame reinforce the arc-shaped fixed plate to prevent the fixed mechanism from loosening, thereby ensuring the stability of the buffer mechanism and the anti-collision mechanism. When the robot is impacted, the inner curved surface of the arc-shaped fixed plate provides guidance for the rotating arc plate to prevent it from deviating during rotation. At the same time, the cooperation of the guide block and the annular guide groove, and the roller and the slide groove, ensures that the anti-collision cylinder rolls along the preset trajectory without jamming or deviating, ensuring that the robot can work stably during normal operation and after impact.

[0016] Fourth, this industrial robot with a collision-resistant chassis structure, equipped with omnidirectional wheels, allows the robot to move flexibly between different work areas and stop stably at the designated location. At the same time, the gimbal rotates horizontally and vertically, causing the camera to adjust the shooting angle and collect images of the work area in real time for operators to monitor. The omnidirectional wheels free the robot from the limitations of a fixed working position, enabling it to adapt to the needs of industrial production in multiple scenarios, improve equipment utilization, and enhance production efficiency.

[0017] V. This industrial robot with an anti-collision chassis structure, through the coordinated arrangement of a fixing mechanism, a buffer mechanism, and an anti-collision mechanism, ensures that when the robot moves or is impacted, the impact force borne by the casters and the impact force transmitted by the anti-collision mechanism are all transmitted to the fixing mechanism through the buffer mechanism, and then dispersed to the base shell by the fixing mechanism. The coordinated cooperation of each structure ensures that the chassis is subjected to uniform force, avoiding deformation or damage to local structures due to concentrated force, greatly improving the overall load-bearing capacity of the chassis, and ensuring the long-term stable operation of the robot.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: an industrial robot with a collision-resistant chassis structure, comprising: The base housing 1 and a cover plate 9 detachably installed at the bottom of the base housing 1. A robotic arm 11 is installed at the middle of the top of the cover plate 9. An actuator 12 is fixedly installed at the end of the robotic arm 11. The robotic arm 11 performs various actions to move the actuator 12 to a designated position to complete industrial operations. A gimbal 13 is installed on one side of the top of the cover plate 9. A camera 14 is installed on the top of the gimbal 13. The gimbal 13 allows the camera 14 to flexibly adjust its angle to achieve all-round monitoring of the working environment. A receiving hole 2 is opened on the side of the base housing 1. An arc-shaped slot block 3 is fixedly installed at the bottom of the inner cavity of the base housing 1. A universal wheel 10 is installed at the bottom of the base housing 1. The universal wheel 10 enables the robot to move in different working scenarios and reach the designated working position. Fixing mechanism 4 is detachably installed on the top of the arc-shaped slot block 3; The buffer mechanism 5 is installed at the edge of the inner cavity of the base housing 1, and the buffer mechanism 5 is engaged with the fixing mechanism 4. The anti-collision mechanism 6 is installed on the buffer mechanism 5. When the robot is hit, the external force contacts the anti-collision mechanism 6, causing it to move on the buffer mechanism 5. The anti-collision mechanism 6 can absorb part of the impact energy. When the anti-collision mechanism 6 moves, the buffer mechanism 5 rotates and works with the fixed mechanism 4 to buffer the impact. There are six receiving holes 2, and the six receiving holes 2 are evenly distributed along the axis of the base housing 1. The anti-collision mechanism 6 is set inside the receiving holes 2, and the anti-collision mechanism 6 can provide all-round anti-collision protection for the robot. There are six arc-shaped slot blocks 3, and the six arc-shaped slot blocks 3 are evenly distributed along the axis of the base housing 1. The top of the fixing mechanism 4 is detachably equipped with a hexagonal fixing cover 7 and a hexagonal fixing frame 8. The hexagonal fixing cover 7 and the hexagonal fixing frame 8 work together to reinforce the fixing mechanism 4, prevent the fixing mechanism 4 from loosening during robot operation, ensure the stability of the fixing structure, and thus ensure the normal operation of other robot components.

[0022] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 10 As shown, the fixing mechanism 4 includes an arc-shaped fixing plate 41, which can be detachably installed inside the arc-shaped slot block 3. The top two ends of the arc-shaped fixing plate 41 have mounting holes 1 42 and 2 43 respectively. The surface of the arc-shaped fixing plate 41 is provided with a mounting groove 44, and the top and bottom of the inner wall of the mounting groove 44 are provided with snap-fit ​​holes 45. The hexagonal fixing cover 7 is detachably installed inside the mounting hole 42 by bolts, and the hexagonal fixing frame 8 is detachably installed inside the mounting hole 43 by bolts, with the hexagonal fixing cover 7 located on the inner side of the hexagonal fixing frame 8. The anti-collision mechanism 6 includes an anti-collision cylinder 61. An annular guide groove 62 is formed in the middle of the outer surface of the anti-collision cylinder 61. An annular groove 63 is formed inside the annular guide groove 62. A slider 64 is slidably installed inside the annular groove 63. A roller 66 is rotatably installed on the outer surface of the slider 64. The roller 66 is set inside the buffer mechanism 5. An arc spring 65 is installed inside the annular groove 63. The two ends of the arc spring 65 are respectively connected to the two sides of the slider 64, and the middle of the arc spring 65 is fixedly installed on the inner wall of the annular groove 63.

[0023] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 10As shown, the buffer mechanism 5 includes a fixed rod 51, which is fixedly installed at the edge of the inner cavity of the base housing 1. A rotating arc plate 52 is rotatably installed on the outer surface of the fixed rod 51. A guide block 55 is fixedly installed on the inner curved surface of the rotating arc plate 52. The guide block 55 is located inside the annular guide groove 62. A sliding groove 56 is opened on the surface of the guide block 55. A roller 66 is located inside the sliding groove 56. When the robot is impacted, the external force first contacts the anti-collision cylinder 61. At this time, the roller 66 rolls in the sliding groove 56. The anti-collision cylinder 61 rolls on the inner curved surface of the rotating arc plate 52 under the combined action of the annular guide groove 62 and the guide block 55. At this time, the slider 64 slides in the annular groove 63, and the arc spring 65 has the ability to absorb deformation. A buffer spring 53 is fixedly installed on the side of the outer curved surface of the rotating arc plate 52 away from the fixed rod 51. The buffer spring 53 is set on the outer curved surface of the arc fixed plate 41. A snap-fit ​​piece 54 is fixedly installed on the other end of the buffer spring 53. The snap-fit ​​piece 54 is detachably installed inside the mounting groove 44. When the anti-collision cylinder 61 rolls on the inner curved surface of the rotating arc plate 52, the rotating arc plate 52 rotates around the fixed rod 51, and the buffer spring 53 is compressed to absorb the impact. The snap-fit ​​component 54 includes a snap-fit ​​block 541. The top and bottom of the snap-fit ​​block 541 are provided with receiving grooves 542. A return spring 543 is fixedly installed inside the receiving groove 542. A snap-fit ​​strip 544 is fixedly installed at the other end of the return spring 543. The snap-fit ​​strip 544 is slidably installed inside the receiving groove 542. The snap-fit ​​component 54 is detachably installed inside the mounting groove 44 to realize the connection between the buffer mechanism 5 and the fixing mechanism 4, so that the two can work together to complete the buffering task. The locking block 541 is slidably installed inside the mounting groove 44, and the locking strip 544 is engaged and matched with the locking hole 45. The detachable installation of the buffer mechanism 5 and the fixing mechanism 4 facilitates the maintenance of the components. The arc-shaped slot block 3 is coaxially arranged with the fixing rod 51. The rotating arc plate 52 is pressed and matched with the inner curved surface of the arc-shaped fixing plate 41. When the rotating arc plate 52 rotates around the fixing rod 51, the inner curved surface of the arc-shaped fixing plate 41 has a guiding effect, which enhances stability.

[0024] When in use, the universal wheels 10 at the bottom drive the robot to move to the designated work area according to the work instructions, and the position is adjusted. The gimbal 13 starts to work, driving the top camera 14 to adjust the monitoring angle, collect images of the work area in real time and transmit them to the control system. The robotic arm 11 moves the actuator 12 to the target position through multi-joint movement to complete the preset industrial operation. When the robot is impacted, the external impact force first acts on the anti-collision cylinder 61 of the anti-collision mechanism 6. Because the receiving holes 2 are evenly distributed, the corresponding anti-collision cylinder 61 can withstand the impact force in all directions. The impact force pushes the anti-collision cylinder 61 to move into the base housing 1. When the anti-collision cylinder 61 moves, its annular guide groove 62 slides along the guide block 55 of the buffer mechanism 5. At the same time, the roller 66 on the outer surface of the slider 64 rolls in the slide groove 56 of the guide block 55, reducing the movement resistance of the anti-collision cylinder 61 and ensuring that it rolls stably along the inner curved surface of the rotating arc plate 52. The rolling of the anti-collision cylinder 61 drives the slider 64 in the annular groove 63 to slide. The slider 64 squeezes the arc springs 65 on both sides, causing the arc springs 65 to undergo elastic deformation, initially absorbing the impact energy and weakening the impact force. When the anti-collision cylinder 61 rolls along the inner curved surface of the rotating arc plate 52, it generates a thrust on the rotating arc plate 52, causing the rotating arc plate 52 to rotate around the fixed rod 51. Because the rotating arc plate 52 is squeezed and matched with the inner curved surface of the arc fixed plate 41, the inner curved surface of the arc fixed plate 41 provides guidance for the rotating arc plate 52, preventing it from deviating and enhancing the buffer stability. When the rotating arc plate 52 rotates, the buffer spring 53 on its outer curved surface is compressed, and the impact energy is absorbed twice through elastic deformation, further reducing the impact force on the base shell 1 and internal components. The arc-shaped fixing plate 41 of the fixing mechanism 4 is fixed in the base housing 1 by the arc-shaped slot block 3, providing support for the buffer spring 53 and ensuring that the buffer spring 53 does not misalign when compressed. The locking block 541 of the locking member 54 is embedded in the mounting groove 44 of the arc-shaped fixing plate 41, and the locking strip 544 is locked with the locking hole 45, so that the buffer mechanism 5 and the fixing mechanism 4 are stably connected, preventing the two from separating during the buffering process and ensuring that the buffering process is continuous and effective. After the impact force disappears, the arc spring 65 releases its elastic potential energy, pushing the slider 64 back to the initial position of the annular groove 63, causing the anti-collision cylinder 61 to roll in the opposite direction along the inner curved surface of the rotating arc plate 52, returning to the initial position. The buffer spring 53 releases its elastic potential energy, pushing the rotating arc plate 52 to rotate in the opposite direction around the fixed rod 51, returning to the standby state. The robot as a whole resumes its normal working state, and the universal wheel 10, robotic arm 11, actuator 12, gimbal 13, camera 14 and other components continue to perform their original work tasks.
