Description

Technical Field

[0001] This invention relates to the field of robotic arm technology, specifically a folding telescopic robotic arm. Background Technology

[0002] In modern industrial automation, logistics warehousing, disaster relief, aerospace and special operations, robotic arms, as actuators, play a key role in extending human operational capabilities and replacing manual labor in completing complex or dangerous tasks. Among them, the working range, flexibility and environmental adaptability of robotic arms are the core indicators for measuring their performance. In order to meet the growing demand for large-range, multi-degree-of-freedom and compact operating equipment, telescopic arm and folding arm technologies have emerged and have received widespread attention and development.

[0003] When existing equipment operates for extended periods, the drive components experience increased friction due to lack of lubrication. Traditional equipment requires shutdown for lubrication, which reduces the robot's working time and consequently decreases work efficiency. Furthermore, manual control of the amount of lubricant added can affect the robot's performance to some extent. When idle, the robot may be damaged by dust or accidental impacts. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides the following technical solution: a folding telescopic arm robotic arm, comprising a support frame, with wheels fixedly connected to the bottom of the support frame via brackets; a fixed end of a first hydraulic rod fixedly connected to the bottom of the inner wall of the support frame; a first connecting plate fixedly connected to the movable end of the first hydraulic rod; a driving mechanism fixedly connected to the top of the first connecting plate; robotic arms fixedly connected to both sides of the driving mechanism; clamping devices fixedly connected to both sides of the execution end of the robotic arms; and two sets of slide rails symmetrically distributed on the top of the support frame. The slide rail has a sliding block slidably connected to its inner wall. A first connecting rod is fixedly connected to one side of the sliding block. A second connecting plate is fixedly connected to one side of the support frame. A protective cover is fixedly connected to the top of the second connecting plate. A first U-shaped telescopic cover is slidably connected through one side of the protective cover. A second U-shaped telescopic cover is slidably connected through the side of the first U-shaped telescopic cover away from the protective cover. The side of the second U-shaped telescopic cover away from the first U-shaped telescopic cover is fixedly connected to the first connecting rod. A transmission assembly is fixedly connected to the bottom part of the inner wall of the support frame located on one side of the first hydraulic rod. One side of the sliding block is rotatably connected to the transmission assembly.

[0005] Preferably, the driving mechanism includes a first bracket, a rotating shaft is rotatably connected through the inner wall of the first bracket, a driven gear is sleeved and fixedly connected on the rotating shaft, a driving gear is meshed on the side of the driven gear, a drive shaft of a first motor is fixedly connected to one side of the driving gear, two sets of the first bracket are provided and symmetrically fixedly connected to the top of the first connecting plate, the first motor is fixedly connected to the top of the first connecting plate, and both ends of the rotating shaft are fixedly connected to the robotic arm.

[0006] Preferably, the driven gear has an oil storage chamber inside its teeth, and an oil outlet is formed at the top of the inner wall of the oil storage chamber. An oil filter cylinder is fixedly connected to the inner wall of the oil outlet, and filter holes are evenly formed on the inner wall of the oil filter cylinder. A first spring is fixedly connected to the bottom of the inner wall of the oil filter cylinder, and a sealing plate is fixedly connected to the top of the first spring. A pressing block is fixedly connected to the top of the sealing plate, and the side of the sealing plate is slidably connected to the inner wall of the oil filter cylinder. When the first motor is started, the driving gear is driven to rotate. Through gear meshing, the driven gear, rotating shaft, and robotic arm rotate. The teeth of the driving gear reciprocate to press the pressing block of the driven gear, pushing the sealing plate to slide against the elastic force of the first spring towards the inner wall of the oil filter cylinder, opening the oil outlet. The lubricating oil in the oil storage chamber flows out through the filter holes to lubricate the gear meshing. After the robotic arm stops, the first spring returns to its original deformation, pushing the sealing plate upward to close the oil outlet. At the same time, the sealing plate scrapes away impurities from the inner wall of the oil filter cylinder to prevent contamination of the lubricating oil.

[0007] Preferably, the clamping device includes a second bracket, a rotating rod rotatably connected to one side of the second bracket, an output end of a belt drive mechanism sleeved and fixedly connected to the rotating rod, a drive shaft of a second motor fixedly connected to the input end of the belt drive mechanism, the second motor fixedly connected to the top of the second bracket, a rotating frame fixedly connected to the end of the rotating rod away from the second bracket, a fixed end of a double-rod hydraulic rod fixedly connected to one side of the inner wall of the rotating frame, a first rotating frame rotatably connected through the top and bottom of both sides of the rotating frame, a connecting frame fixedly connected to both ends of the double-rod hydraulic rod, a second rotating frame rotatably connected through both ends of the connecting frame, a second rotating frame rotatably connected to the end of the second rotating frame away from the connecting frame, a disassembly mechanism fixedly connected to the end of the first rotating frame away from the second rotating frame, a clamping plate fixedly connected to one side of the disassembly mechanism, two sets of clamping plates symmetrically fixedly connected to both sides of the robotic arm execution end of the second bracket, the clamping plate at the top of the rotating frame being semi-circular, and the clamping plate at the bottom of the rotating frame being square.

[0008] Preferably, the disassembly mechanism includes a first fixing plate and a second fixing plate. The top and bottom of the first fixing plate are both fixedly connected to connecting seats via brackets. A rotating groove is formed on one side of the connecting seat. A second spring is fixedly connected to the top of the inner wall of the rotating groove. Rotating blocks are rotatably connected to both sides of the inner wall of the rotating groove. One side of each rotating block is fixedly connected to one end of the second spring. A wedge-shaped limiting block is fixedly connected to the side of the rotating block away from the first fixing plate. A first connecting block and a second connecting block are fixedly connected to the sides of the first and second fixing plates, respectively. Two sets of the first connecting blocks are symmetrically distributed on one side of the first fixing plate, and two sets of the first connecting blocks are symmetrically distributed on one side of the second fixing plate. A threaded groove is formed on one side of the first connecting block. A threaded rod is threaded through and threaded to the side of the second connecting block. A knob is fixedly connected to one end of the threaded rod. The end of the threaded rod away from the knob extends into the threaded groove and is threadedly connected to the inner wall of the threaded groove. The top and bottom of the second fixing plate are provided with slots, the shape of which is adapted to the shape of the wedge-shaped limiting block. The bottom of the first fixing plate is fixedly connected to the first rotating frame, and the side of the second fixing plate is fixedly connected to the clamping plate. When disassembling, rotating the knob drives the threaded rod to rotate, causing it to exit from the threaded groove of the first connecting block, thus releasing the threaded fixation. Moving the wedge-shaped limiting block causes the rotating block to rotate in the rotating groove and overcome the second spring force, causing the wedge-shaped limiting block to exit from the slot, thus releasing the limiting fixation. The second fixing plate and clamping plate can then be removed. When installing, align the slot of the second fixing plate with the wedge-shaped limiting block, push the second fixing plate so that the wedge-shaped limiting block is inserted into the slot under the second spring force, completing the initial positioning. Rotating the knob drives the threaded rod to screw into the threaded groove, achieving a stable fixation.

[0009] Preferably, the transmission assembly includes a third bracket, a third fixing plate fixedly connected to the top of the third bracket, an adjusting rod slidably connected through the top of the third fixing plate, a second connecting rod fixedly connected to the bottom of the adjusting rod, third springs evenly fixedly connected to the bottom of the second connecting rod, third connecting rods fixedly connected to both ends of the second connecting rod, a third rotating frame sleeved and rotatably connected to the third connecting rod, the third bracket fixedly connected to the bottom of the inner wall of the support frame, the bottom of the third spring fixedly connected to the bottom of the inner wall of the support frame, and the third rotating frame located away from the third connecting rod. One end is rotatably connected to the sliding block. When the robot arm is idle and folded, one end rests on the adjusting rod. The first hydraulic rod is activated, and the robot arm's own weight moves the adjusting rod downward. Then, through the linkage of the second connecting rod, the third connecting rod, and the third rotating frame, the sliding block is pushed to slide along the slide rail, which moves the first connecting rod. This causes the second U-shaped telescopic cover and the first U-shaped telescopic cover to open in sequence, completely enclosing the robot arm within the support frame for protection. When the robot arm is working, the first hydraulic rod rises, the robot arm unfolds, and the adjusting rod moves upward under the action of the third spring. Through the linkage mechanism, the telescopic cover retracts to a position that does not affect the operation.

[0010] This invention provides a foldable telescopic arm robotic arm. It has the following advantages: 1. This foldable telescopic arm robot, when the arm rotates, the teeth of the drive gear reciprocate to press the squeeze block of the driven gear, driving the sealing plate to overcome the spring force and open the oil outlet. The lubricating oil in the oil storage chamber is precisely dripped into the gear meshing point through the oil filter hole, realizing automatic lubrication as soon as it rotates. There is no need for manual stopping to add lubricating oil, which improves the working efficiency of the robot. The lubricating oil can effectively reduce the friction loss at the gear meshing point and extend the service life of the robot's drive parts. When the robot arm stops rotating, the spring pushes the sealing plate to reset and close the oil outlet, avoiding the waste of lubricating oil. At the same time, when the sealing plate rebounds, it scrapes the impurities on the inner wall of the oil filter cylinder to prevent impurities from mixing into the oil storage chamber and contaminating the lubricating oil, ensuring a continuous and stable lubrication effect, avoiding gear jamming and accelerated wear caused by impurities, and reducing the equipment failure rate.

[0011] 2. This foldable telescopic arm robot uses a second motor to drive the rotating frame to rotate, allowing for quick switching between semi-circular and square clamping plates. It can adapt to workpieces of different shapes, such as round and square, without the need to change the clamps. This improves flexibility and adaptability, as there is no need to change to special clamps for different workpiece shapes. The dual hydraulic rods drive the clamping plates to move towards each other, and the clamping force and range can be precisely controlled by adjusting the telescopic amount, adapting to clamping needs of different sizes and improving the robot's flexibility and work efficiency.

[0012] 3. This foldable telescopic arm robot adopts a dual connection structure of knob thread fixing and wedge-shaped limiting block limiting. When disassembling and assembling the clamping plate, no complicated tools are required. Simply rotate the knob to release the threaded connection and move the wedge-shaped block to remove the clamping plate. During installation, the wedge-shaped block is automatically driven into the slot by the spring to achieve initial positioning. Then, tighten the knob to complete the fixation. This lowers the maintenance threshold. The clamping plate can be replaced, cleaned or repaired without professional technicians, reducing equipment downtime for maintenance, ensuring continuous operation, and further enhancing the practicality of the robot.

[0013] 4. When the folding telescopic arm is idle and folded, the first hydraulic rod, in conjunction with its own weight, drives the first and second U-shaped telescopic covers to automatically unfold, completely enclosing the arm within the support frame and forming a protective space. This effectively blocks external contaminants such as dust, oil, and water stains, while also preventing physical damage to the equipment caused by collisions, falls, or other accidents, thus extending the arm's service life. When the arm is in operation, the telescopic covers automatically retract to a position that does not interfere with the work, eliminating the need for manual operation and achieving automated switching between idle protection and work avoidance, thereby improving ease of use.

[0016] 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.

[0017] For the first embodiment, please refer to... Figures 1-4This invention provides a technical solution: a folding telescopic arm robotic arm, comprising a support frame 1, with wheels 2 fixedly connected to the bottom of the support frame 1 via brackets; a fixed end of a first hydraulic rod 3 fixedly connected to the bottom inner wall of the support frame 1; a first connecting plate 4 fixedly connected to the movable end of the first hydraulic rod 3; a drive mechanism 5 fixedly connected to the top of the first connecting plate 4; robotic arms 6 fixedly connected to both sides of the drive mechanism 5; clamping devices 7 fixedly connected to both sides of the execution end of the robotic arms 6; and a slide rail 8 fixedly connected to the top of the support frame 1, with two sets of slide rails 8 arranged symmetrically. A sliding block 9 is slidably connected to the inner wall of a slide rail 8, which is placed on top of the support frame 1. A first connecting rod 10 is fixedly connected to one side of the sliding block 9. A second connecting plate 11 is fixedly connected to one side of the support frame 1. A protective cover 12 is fixedly connected to the top of the second connecting plate 11. A first U-shaped telescopic cover 13 is slidably connected through one side of the protective cover 12. A second U-shaped telescopic cover 14 is slidably connected through one side of the first U-shaped telescopic cover 13 away from the protective cover 12. The side of the second U-shaped telescopic cover 14 away from the first U-shaped telescopic cover 13 is fixedly connected to the first connecting rod 10. The inner wall of the support frame 1... A transmission assembly 15 is fixedly connected to the bottom portion located on one side of the first hydraulic rod 3. One side of the sliding block 9 is rotatably connected to the transmission assembly 15. The drive mechanism 5 includes a first bracket 51. A rotating shaft 52 is rotatably connected through the inner wall of the first bracket 51. A driven gear 53 is sleeved on and fixedly connected to the rotating shaft 52. A driving gear 54 meshes with the side of the driven gear 53. The drive shaft of the first motor 55 is fixedly connected to one side of the driving gear 54. Two sets of first brackets 51 are symmetrically fixedly connected to the top of the first connecting plate 4. The first motor 55 is fixedly connected to the first connecting plate. 4. At the top, the two ends of the rotating shaft 52 are fixedly connected to the robotic arm 6. An oil storage chamber 531 is opened inside the teeth of the driven gear 53. An oil outlet 532 is opened at the top of the inner wall of the oil storage chamber 531. An oil filter cylinder 533 is fixedly connected to the inner wall of the oil outlet 532. Oil filter holes 534 are evenly opened on the inner wall of the oil filter cylinder 533. A first spring 535 is fixedly connected to the bottom of the inner wall of the oil filter cylinder 533. A sealing plate 536 is fixedly connected to the top of the first spring 535. A squeezing block 537 is fixedly connected to the top of the sealing plate 536. The side of the sealing plate 536 is slidably connected to the inner wall of the oil filter cylinder 533.

[0018] In use, the first motor 55 is started, and the drive shaft of the first motor 55 drives the drive gear 54 to rotate. Since the drive gear 54 meshes with the driven gear 53 on the side, the rotation of the drive gear 54 will drive the driven gear 53 to rotate. The rotation of the driven gear 53 will drive the rotating shaft 52 to rotate, which in turn will drive the robotic arm 6 to rotate. Since the oil storage chamber 531 is set with two sets, during the rotation of the robotic arm 6, the teeth of the drive gear 54 will have a reciprocating squeezing effect on the squeezing block 537 on the teeth of the driven gear 53. The squeezing action of the squeezing block 537 will drive the sealing plate 536 to slide towards the inner wall of the oil filter cylinder 533, so that the sealing plate 536 will move downward against the elastic force of the first spring 535, thereby opening the oil outlet 532. The lubricating oil in the oil storage chamber 531 flows out through the oil filter hole 534 on the oil filter cylinder 533, lubricating the meshing joint of the driven gear 53 and the driving gear 54, reducing wear caused by long-term operation and extending service life. When the robotic arm 6 stops rotating, the first spring 535 returns to its original deformation, pushing the sealing plate 536 upward to re-close the oil outlet 532. At the same time, if impurities enter the oil filter cylinder 533 during lubrication, the sealing plate 536 will scrape off the impurities on the inner wall of the oil filter cylinder 533 when it rebounds, preventing impurities from contaminating the lubricating oil in the oil storage chamber 531 and further improving the lubrication effect. Under the repeated lubrication, there is no need for manual shutdown for maintenance and lubrication, thereby improving the working efficiency of the robotic arm.

[0019] For the second embodiment, please refer to... Figures 1-5 Based on the first embodiment, the present invention provides a technical solution: the clamping device 7 includes a second bracket 71, a rotating rod 72 rotatably connected to one side of the second bracket 71, an output end of a belt drive mechanism 73 sleeved and fixedly connected to the rotating rod 72, a drive shaft of a second motor 74 fixedly connected to the input end of the belt drive mechanism 73, the second motor 74 fixedly connected to the top of the second bracket 71, a rotating frame 75 fixedly connected to the end of the rotating rod 72 away from the second bracket 71, a fixed end of a double-rod hydraulic rod 76 fixedly connected to one side of the inner wall of the rotating frame 75, and a first rotating frame rotatably connected through and to the top and bottom of both sides of the rotating frame 75. 77. Both ends of the double-bar hydraulic rod 76 are fixedly connected to the connecting frame 78. Both ends of the connecting frame 78 are rotatably connected to the second rotating frame 710. The end of the second rotating frame 710 away from the connecting frame 78 is rotatably connected to the first rotating frame 77. The end of the first rotating frame 77 away from the second rotating frame 710 is fixedly connected to the disassembly mechanism 79. A clamping plate 711 is fixedly connected to one side of the disassembly mechanism 79. The second bracket 71 is provided with two sets and is symmetrically fixedly connected to both sides of the execution end of the robotic arm 6. The clamping plate 711 at the top of the rotating frame 75 is set to a semi-circular arc shape, and the clamping plate 711 at the bottom of the rotating frame 75 is set to a square shape.

[0020] In use, when clamping a round object, the second motor 74 is activated. The drive shaft of the second motor 74 drives the input end of the belt drive mechanism 73 to rotate, which in turn drives the output end to rotate. The output end drives the rotating rod 72 to rotate, which in turn drives the rotating frame 75 to rotate. This causes the semi-circular clamping plate 711 at the top of the rotating frame 75 to rotate downwards, and the square clamping plate 711 at the bottom of the rotating frame 75 to rotate upwards. At this time, the semi-circular clamping plate 711 is directly facing the round object. The double-rod hydraulic rod 76 is then activated, and its movable ends extend to both sides, driving the second rotating frame 710 to rotate via the connecting frame 78. The second rotating frame 710 then drives the first rotating frame. 77 rotates, causing the clamping plate 711 to move closer to the center. The semi-circular clamping plate 711 clamps the round object from both sides, achieving stable clamping of the round object. When it is necessary to clamp a square object, the second motor 74 is started again, causing the rotating frame 75 to rotate, so that the square clamping plate 711 rotates to face the square object from below. Similarly, the double-bar hydraulic rod 76 is started, causing the clamping plate 711 to move closer to the center. The square clamping plate 711 clamps the square object from all sides. Thus, it is possible to complete flexible clamping operations on objects of different shapes without frequently changing the clamps. Moreover, the size of the clamped object can be controlled by the extension and retraction of the double-bar hydraulic rod 76, thereby improving the flexibility and adaptability of the robot.

[0021] Third embodiment, please refer to Figures 1-7Based on the second embodiment, the present invention provides a technical solution: the disassembly mechanism 79 includes a first fixing plate 791 and a second fixing plate 797. The top and bottom of the first fixing plate 791 are fixedly connected to connecting seats 792 via brackets. A rotating groove 793 is provided on one side of the connecting seat 792. A second spring 794 is fixedly connected to the top of the inner wall of the rotating groove 793. Rotating blocks 795 are rotatably connected to both sides of the inner wall of the rotating groove 793. One side of the rotating block 795 is fixedly connected to one end of the second spring 794. A wedge-shaped limiting block 796 is fixedly connected to the side of the rotating block 795 away from the first fixing plate 791. A first connecting block 798 and a second connecting block 799 are fixedly connected to the sides of the first fixing plate 791 and the second fixing plate 797, respectively. The first connecting block 798 is provided with two... Two sets of first connecting blocks 798 are symmetrically distributed on one side of the first fixed plate 791. Two sets of first connecting blocks 798 are symmetrically distributed on one side of the second fixed plate 797. A threaded groove 7910 is opened on one side of the first connecting block 798. A threaded rod 7911 is threaded through and threaded to the side of the second connecting block 799. A knob 7912 is fixedly connected to one end of the threaded rod 7911. The end of the threaded rod 7911 away from the knob 7912 extends into the threaded groove 7910 and is threaded to the inner wall of the threaded groove 7910. Slots 7913 are opened at the top and bottom of the second fixed plate 797. The shape of the slots 7913 is adapted to the shape of the wedge-shaped limiting insert 796. The bottom of the first fixed plate 791 is fixedly connected to the first rotating frame 77. The side of the second fixed plate 797 is fixedly connected to the clamping plate 711.

[0022] In use, when it is necessary to disassemble, replace, or maintain the clamping plate 711, first rotate the knob 7912. The knob 7912 drives the threaded rod 7911 to rotate. Since the threaded rod 7911 is threadedly connected to the second connecting block 799 and one end extends into the threaded groove 7910 of the first connecting block 798, the rotation of the threaded rod 7911 will gradually pull it out of the threaded groove 7910, releasing the threaded connection between the first fixing plate 791 and the second fixing plate 797. Next, move the wedge-shaped limiting block 796. The wedge-shaped limiting block 796 drives the rotating block 795 to rotate in the rotating groove 793, while overcoming the elastic force of the second spring 794, causing the wedge-shaped limiting block 796 to exit from the slot 7913, releasing the limiting connection between the first fixing plate 791 and the second fixing plate 797. At this time, the second fixing plate 797, together with the clamping plate 711, can be removed from the first fixing plate 791 for replacement or maintenance. When reinstallation is required after replacement or maintenance, first align the slot 7913 on the second fixing plate 797 with the wedge-shaped limiting block 796, then push the second fixing plate 797 so that the wedge-shaped limiting block 796 is engaged in the slot 7913 under the elastic force of the second spring 794, achieving initial positioning, aligning the threaded rod 7911 with the threaded groove 7910, then rotate the knob 7912, which drives the threaded rod 7911 to rotate, so that one end of the threaded rod 7911 is gradually screwed into the threaded groove 7910 of the first connecting block 798, until the threaded rod 7911 is tightly threadedly connected to the inner wall of the threaded groove 7910, completing the threaded fixed connection between the first fixing plate 791 and the second fixing plate 797, thereby quickly and stably completing the installation of the clamping plate 711, achieving quick assembly and disassembly without the use of complex tools, greatly improving maintenance efficiency, and further enhancing the practicality and convenience of the robot.

[0023] For the fourth embodiment, please refer to [link / reference]. Figures 1-8 Based on the third embodiment, the present invention provides a technical solution: the transmission assembly 15 includes a third bracket 151, a third fixing plate 152 is fixedly connected to the top of the third bracket 151, an adjusting rod 153 is slidably connected through the top of the third fixing plate 152, a second connecting rod 154 is fixedly connected to the bottom of the adjusting rod 153, a third spring 155 is evenly fixedly connected to the bottom of the second connecting rod 154, a third connecting rod 156 is fixedly connected to both ends of the second connecting rod 154, a third rotating frame 157 is sleeved on and rotatably connected to the third connecting rod 156, the third bracket 151 is fixedly connected to the bottom of the inner wall of the support frame 1, the bottom of the third spring 155 is fixedly connected to the bottom of the inner wall of the support frame 1, and the end of the third rotating frame 157 away from the third connecting rod 156 is rotatably connected to one side of the sliding block 9.

[0024] In use, after the robotic arm is folded up, one end rests on the adjusting rod 153 on the third fixed plate 152. Then, the first hydraulic rod 3 is activated. The push of the first hydraulic rod 3 and the weight of the robotic arm itself cause the adjusting rod 153 to move downward. The downward movement of the adjusting rod 153 causes the second connecting rod 154 to move downward. The downward movement of the second connecting rod 154 compresses the third spring 155. At the same time, the third connecting rods 156 at both ends of the second connecting rod 154 also move downward. The downward movement of the third connecting rods 156 causes the third rotating frame 157 to rotate. The rotation of the third rotating frame 157 then pulls the sliding block 9. The robot arm slides within the slide rail 8, and the sliding block 9 moves the first connecting rod 10. The movement of the first connecting rod 10 causes the second U-shaped telescopic cover 14 to open. During the opening process, the second U-shaped telescopic cover 14 slowly opens the first U-shaped telescopic cover 13. Finally, when the robot arm is completely folded into the support frame 1, the second U-shaped telescopic cover 14 and the first U-shaped telescopic cover 13 completely protect the robot arm inside the support frame 1. This provides protection for the robot arm after use, preventing it from being disturbed or damaged by external factors such as dust and collisions when idle, effectively extending the robot arm's service life, and thus achieving the goal of protecting the robot arm. Further adjustments and stabilization of the folded state of the robotic arm: When the robotic arm is used, the first hydraulic rod 3 rises, and the robotic arm unfolds simultaneously. This causes the adjusting rod 153 to slowly move upward under the elastic force of the third spring 155. The upward movement of the adjusting rod 153 drives the second connecting rod 154 to move upward. The upward movement of the second connecting rod 154 causes the compressed third spring 155 to gradually return to its original state. At the same time, the third connecting rods 156 at both ends of the second connecting rod 154 also rise. The rise of the third connecting rods 156 drives the third rotating frame 157 to rotate in the opposite direction. The reverse rotation of the third rotating frame 157 then pushes the sliding block 9 to rotate in the slide rail 8. The sliding block 9 slides in the opposite direction, causing the first connecting rod 10 to move in the opposite direction. The first connecting rod 10 moves in the opposite direction, causing the second U-shaped telescopic cover 14 to retract. During the retraction process, the second U-shaped telescopic cover 14 slowly retracts the first U-shaped telescopic cover 13. Finally, when the robot is fully extended to the working state, the second U-shaped telescopic cover 14 and the first U-shaped telescopic cover 13 retract to a position that does not affect the normal operation of the robot. Thus, it can be well protected when idle and will not be obstructed by the telescopic cover when working. Moreover, the whole process is automated and can be completed without human intervention, which improves the convenience of using the robot.
