Description

Technical Field

[0001] This invention belongs to the field of robotics technology, and in particular relates to a connection base for an industrial robot. Background Technology

[0002] Industrial robots are multi-jointed manipulators or multi-degree-of-freedom machines designed for industrial applications. They can automatically perform tasks and rely on their own power and control capabilities to achieve various functions. They can be commanded by humans or operate according to pre-programmed procedures. Modern industrial robots can also act according to principles established using artificial intelligence technology. Industrial robots require a mounting base for installation.

[0003] In practical applications of industrial robots, the precise installation and stable connection between the robot body and its docking base are crucial. To achieve high-precision operations, the robot body typically uses its flange to precisely mate with a specific structure on the docking base. However, in the robot's working environment, especially in the presence of dust, debris, and other particulate matter, these tiny particles can easily adhere to the precision mating surfaces of the robot flange and the docking base, or accumulate in and around the locating pin holes.

[0004] Of particular note is that when hard particles adhere to the mating surfaces, these particles may become trapped between the mating surfaces during the docking process. This can prevent the robot flange and the base from achieving an ideal, complete fit, resulting in a tiny installation gap and creating a so-called "false installation posture." This posture error directly affects the accuracy of subsequent operations.

[0005] Furthermore, dust in the environment can also clog the positioning pin holes or adhere to the surface of the positioning pins. Both of these situations will prevent the positioning pins from being smoothly and fully inserted into the pin holes, causing the positioning pins to fail to be accurately positioned. Since the positioning pins play a crucial role in the robot's repetitive positioning process, any deviation in their insertion state will directly cause the robot to lose the required repeatability accuracy, thereby affecting the stability and reliability of the entire automation system.

[0006] Based on this, the present invention designs a connection base for industrial robots to solve the above problems. Summary of the Invention

A moving vibration mechanism is fixedly connected below the first elastic connecting mechanisms and located below the mounting plate. A buffer cleaning mechanism is fixedly connected to the support plate and located below the mounting plate.

[0010] As a further description of the above technical solution:

[0011] The sliding connection mechanism includes a movable limiting plate, two side plates, and a sliding block fixedly connected to the sliding contact plate. The movable limiting plate is slidably connected in the limiting groove, and the movable limiting plate has a sliding groove.

[0012] As a further description of the above technical solution:

[0013] The sliding block is slidably connected in the sliding groove, and a connecting column is connected through the side of the movable limiting plate. A guide hole is opened through the side of the side plate, and the connecting column is slidably connected in the guide hole. The guide hole consists of a vertical section and an inclined section, and is used to guide the connecting column and the movable limiting plate to move in the horizontal direction.

[0014] As a further description of the above technical solution:

[0015] The first elastic connection mechanism includes a first extension plate fixedly connected to the sliding contact plate, a first support rod slidably connected through the first extension plate, the first support rod being fixedly connected to the mounting plate, and a first spring being sleeved on the first support rod, with both ends of the first spring being fixedly connected to the first extension plate and the mounting plate, respectively.

[0016] As a further description of the above technical solution:

[0017] The moving vibration mechanism includes a vertical plate and a positioning plate fixedly connected to the mounting plate. The vertical plate is fixedly connected to the first extension plate. An elastic telescopic rod is fixedly connected to the side of the vertical plate, and an intermediate plate is fixedly connected to the end of the elastic telescopic rod.

[0018] As a further description of the above technical solution:

[0019] The middle plate has sliding teeth fixedly connected to its side, and the positioning plate has pressing teeth installed on the side near the sliding teeth. The sliding teeth are located between the pressing teeth. The middle plate has a striking rod fixedly connected to its side, and the striking rod is located on the side of the positioning plate.

[0020] As a further description of the above technical solution:

[0021] The second elastic connection mechanism includes a second extension plate, which is fixedly connected to the side of the connecting plate. A second support rod is slidably connected through the second extension plate. A circular plate is fixedly connected to the bottom end of the second support rod. A second spring is sleeved on the second support rod. The two ends of the second spring are fixedly connected to the mounting plate and the second extension plate, respectively.

[0022] As a further description of the above technical solution:

[0023] The buffer cleaning mechanism includes an air storage frame fixedly connected to a support plate, a squeezing plate slidably connected inside the air storage frame, a vertical rod fixedly connected to the squeezing plate, the vertical rod slidably connected through the air storage frame, a movable plate fixedly connected to the top of the vertical rod, and a third spring fixedly connected below the squeezing plate, the third spring being fixedly connected to the inner wall of the air storage frame.

[0024] As a further description of the above technical solution:

[0025] The side of the gas storage frame is connected to an air inlet valve and an air outlet valve. Both the air inlet valve and the air outlet valve are connected to the space inside the gas storage frame located below the extrusion plate. The side of the air outlet valve is connected to a connecting pipe. The connecting pipe is connected to a first air outlet pipe and a second air outlet pipe. The first air outlet pipe is fitted with a fixing sleeve connected to the mounting plate.

[0026] As a further description of the above technical solution:

[0027] Both ends of the first air outlet pipe are connected to a first air blowing head. The first air blowing head is inclined and is used to blow gas into the threaded mounting hole. The second air outlet pipe is connected to a second air blowing head on the side near the mounting plate. The position of the second air blowing head corresponds to the position on the upper surface of the mounting plate.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. In this invention, an installation plate, a movable plate, an air storage frame, a first air blowing head, a second air blowing head, and a sliding contact plate are used. When the connecting plate moves downwards for installation, its action automatically triggers the entire cleaning process. The movable plate is squeezed downwards, and through the action of the vertical rod, the squeezing plate is driven to orderly discharge the gas in the air storage frame, forming a clean airflow. The discharged gas first passes through the first air blowing head and is precisely blown into the threaded installation hole at a high-speed inclined angle. This design can effectively remove debris and dust adhering to or accumulated on the inner wall of the hole, ensuring the cleanliness of the threaded interface. The second air blowing head guides the airflow to the upper surface of the installation plate. An airflow can blow away dust and fine debris adhering to the surface of the mounting plate, causing them to fall into the area above the connecting plate through pre-set drop holes, or be blown directly off the mounting plate. This not only cleans the contact surface between the mounting plate and the robot flange, but also creates a clean environment for subsequent installation. Through the above dual cleaning mechanism, the present invention can automatically and efficiently remove debris and dust that may affect the installation accuracy. This effectively avoids the problem of hard particles getting stuck on the mating surface or blocking the positioning pin holes, ensuring that the robot body and the connecting base can achieve an ideal fit, maintaining a high-precision installation posture and reliable repeatability.

[0030] 2. In this invention, a sliding contact plate, a first extension plate, extrusion teeth, sliding teeth, an elastic telescopic rod, and a striking rod are employed. During the overall downward movement of the connecting plate and the mounting plate, the sliding contact plate and the first extension plate work together to drive the sliding teeth to move along a predetermined trajectory. When the sliding teeth precisely pass over the extrusion teeth they engage with, the pre-pressed elastic telescopic rod rapidly releases its stored elastic potential energy. This release process causes the sliding teeth and the striking rod connected to them to produce a rapid and powerful reset motion. The striking rod then applies a precise impact force to the positioning plate. This impact force is efficiently transmitted to the mounting plate, thereby generating controllable mechanical vibration in the mounting plate and its key areas. This vibration is not an isolated action but forms a perfect synergy with the previously described air-blowing cleaning mechanism. The vibration can effectively overcome static friction, loosen and peel off stubborn adhering debris that is difficult to remove by simple airflow due to electrostatic adsorption, micro-mechanical interlocking, or physical embedding. Through the dual action of "air-blowing + vibration," this invention can more thoroughly remove various contaminants adhering to the inner wall of the threaded mounting hole and the surface of the mounting plate.

[0031] 3. In this invention, a sliding contact plate, a first spring, a second spring, and a third spring are used. The first and second springs are stretched synchronously, while the third spring is compressed. These four spring elements work together to effectively absorb and disperse the impact kinetic energy of the robot, significantly slowing down the relative movement speed, thereby avoiding violent collisions that may occur between the robot body and the connecting base. This buffer design greatly improves the stability and safety of the installation process, reducing structural damage or precision deviations that may be caused by excessive impact force. When the robot is installed in place and the sliding contact plate passes a specific position, the stretched second spring, with its rebound force, can quickly and automatically drive the connecting plate and the sealing block linked with it to perform a reset movement. After reset, the sealing block can be tightly and accurately inserted into the preset drop hole, effectively sealing the channel. This buffer and reset mechanism not only protects the installed components from damage but also ensures the consistency of the state after installation. The automatic sealing effect of the sealing block prevents debris cleaned up during installation from accidentally entering the sensitive area inside the connecting base, and also keeps the outside of the connecting base clean.

[0046] 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.

[0047] Please see the appendix Figure 1 - Appendix Figure 12This invention provides a technical solution: a connecting base for an industrial robot, comprising a support plate 1, four support frames 2 fixedly mounted on the support plate 1, an mounting plate 3 fixedly connected to the support frames 2, four threaded mounting holes 4 on the mounting plate 3, two sliding holes 5 and a drop hole 6 on the mounting plate 3, a sliding contact plate 7 slidably connected in the sliding hole 5, a sliding connecting mechanism 8 fixedly connected below the sliding contact plate 7, a sealing block 9 slidably connected in the drop hole 6, a connecting plate 10 fixedly connected below the sealing block 9, a limiting groove 11 on the side of the connecting plate 10, the sliding connecting mechanism 8 being disposed in the limiting groove 11, two first elastic connecting mechanisms 12 fixedly connected below the sliding contact plate 7 and disposed below the mounting plate 3, a second elastic connecting mechanism 14 fixedly connected below the mounting plate 3 and disposed below the first elastic connecting mechanism 12, a moving vibration mechanism 13 fixedly connected below the mounting plate 3, and a buffer cleaning mechanism 15 fixedly connected to the support plate 1 and disposed below the mounting plate 3.

[0048] Specifically, such as Figure 4-7 As shown, the sliding connection mechanism 8 includes a movable limiting plate 82, two side plates 86, and a sliding block 81 fixedly connected to the sliding contact plate 7. The movable limiting plate 82 is slidably connected in the limiting groove 11, and a sliding groove 83 is provided on the movable limiting plate 82.

[0049] The sliding block 81 is slidably connected in the sliding groove 83. The side of the movable limiting plate 82 is connected to the connecting column 84. The side of the side plate 86 is provided with a guide hole 85. The connecting column 84 is slidably connected in the guide hole 85. The guide hole 85 is composed of a vertical section and an inclined section, which is used to guide the connecting column 84 and the movable limiting plate 82 to move in the horizontal direction.

[0050] The sliding contact plate 7 is used to control the downward movement of the robot by moving the moving limit plate 82 and the blocking block 9 downward. The downward movement of the sliding contact plate 7 controls the downward movement of the moving limit plate 82, the connecting plate 10 and the blocking block 9 through the sliding block 81. At the same time as the moving limit plate 82 moves downward, the connecting column 84 moves along the guide hole 85. When the connecting column 84 moves to the inclined section of the guide hole 85, the moving limit plate 82 separates from the limit groove 11.

[0051] Specifically, such as Figure 4-5 and Figure 8 As shown, the first elastic connection mechanism 12 includes a first extension plate 121 fixedly connected to the sliding contact plate 7. A first support rod 122 is slidably connected through the first extension plate 121. The first support rod 122 is fixedly connected to the mounting plate 3. A first spring 123 is sleeved on the first support rod 122. The two ends of the first spring 123 are fixedly connected to the first extension plate 121 and the mounting plate 3, respectively.

[0052] The first support rod 122 and the first extension plate 121 guide and limit the downward movement of the sliding contact plate 7, and the first spring 123 buffers the downward movement of the sliding contact plate 7 and controls the upward movement of the sliding contact plate 7 to reset after the sliding contact plate 7 loses pressure.

[0053] Specifically, such as Figure 4-5 and Figure 8-9 As shown, the moving vibration mechanism 13 includes a vertical plate 131 and a positioning plate 134 fixedly connected to the mounting plate 3. The vertical plate 131 is fixedly connected to the first extension plate 121. An elastic telescopic rod 132 is fixedly connected to the side of the vertical plate 131, and an intermediate plate 133 is fixedly connected to the end of the elastic telescopic rod 132.

[0054] A sliding tooth 135 is fixedly connected to the side of the intermediate plate 133. A pressing tooth 137 is installed on the side of the positioning plate 134 near the sliding tooth 135. The sliding tooth 135 is located between the pressing teeth 137. A striking rod 136 is fixedly connected to the side of the intermediate plate 133. The striking rod 136 is located on the side of the positioning plate 134.

[0055] During the downward movement of the first extension plate 121, the sliding tooth 135 will be controlled to move downward. When the sliding tooth 135 passes the pressing tooth 137, the elastic force of the elastic telescopic rod 132 controls the sliding tooth 135 and the striking rod 136 to quickly reset, so that the striking rod 136 acts on the positioning plate 134 and the vibration is transmitted to the mounting plate 3 through the positioning plate 134.

[0056] Specifically, such as Figure 1-5 and Figure 10 As shown, the second elastic connection mechanism 14 includes a second extension plate 141, which is fixedly connected to the side of the connecting plate 10. A second support rod 142 is slidably connected through the second extension plate 141. A circular plate 143 is fixedly connected to the bottom end of the second support rod 142. A second spring 144 is sleeved on the second support rod 142. The two ends of the second spring 144 are fixedly connected to the mounting plate 3 and the second extension plate 141, respectively.

[0057] The second support rod 142 and the second extension plate 141 guide and limit the movement of the connecting plate 10 and the sealing block 9, ensuring that the sealing block 9 moves stably in the vertical direction. The elastic force of the second spring 144 can ensure that the sealing block 9 is stably positioned on the inner wall of the drop hole 6 without external tension. The connecting plate 10 is used to catch the debris falling into the drop hole 6.

[0058] Specifically, such as Figure 1-4 and Figure 11-12As shown, the buffer cleaning mechanism 15 includes an air storage frame 1501 fixedly connected to the support plate 1, a squeezing plate 1502 slidably connected inside the air storage frame 1501, a vertical rod 1503 fixedly connected to the squeezing plate 1502, the vertical rod 1503 slidably connected through the air storage frame 1501, a moving plate 1504 fixedly connected to the top of the vertical rod 1503, and a third spring 1505 fixedly connected to the bottom of the squeezing plate 1502, the third spring 1505 being fixedly connected to the inner wall of the air storage frame 1501.

[0059] The side of the air storage frame 1501 is connected to an air inlet valve 1506 and an air outlet valve 1507. Both the air inlet valve 1506 and the air outlet valve 1507 are connected to the space inside the air storage frame 1501 located below the extrusion plate 1502. The side of the air outlet valve 1507 is connected to a connecting pipe 1508. The connecting pipe 1508 is connected to a first air outlet pipe 1509 and a second air outlet pipe 1512. The first air outlet pipe 1509 is covered with a fixing sleeve 1511 connected to the mounting plate 3.

[0060] Both ends of the first air outlet pipe 1509 are connected to a first air blowing head 1510. The first air blowing head 1510 is inclined and is used to blow gas into the threaded mounting hole 4. The second air outlet pipe 1512 is connected to a second air blowing head 1513 on the side near the mounting plate 3. The position of the second air blowing head 1513 corresponds to the position on the upper surface of the mounting plate 3.

[0061] During the downward movement of the connecting plate 10, the moving plate 1504 is squeezed and moved downward. When the moving plate 1504 moves, the squeezing plate 1502 is controlled to move downward by the vertical rod 1503. The squeezing plate 1502 squeezes the gas in the air storage frame 1501 and discharges it, so that the downward movement of the moving plate 1504 is buffered. At the same time, the first spring 123 and the second spring 144 are stretched, so that the process of the robot moving downward to contact the mounting plate 3 is buffered and there will be no violent impact. The gas in the air storage frame 1501 is squeezed and discharged through the air outlet valve 1507 and the connecting pipe 1508. The first air blowing head 1510 blows the gas quickly and obliquely into the threaded mounting hole 4 to clean the debris and dust on the inner wall of the threaded mounting hole 4. The second air blowing head 1513 blows the gas onto the upper surface of the mounting plate 3. During the upward movement and reset process of the squeezing plate 1502, the external gas is drawn into the air storage frame 1501 through the air inlet valve 1506.

[0062] Working principle and usage:

[0063] When the robot needs to be installed, simply align the bottom of the robot with the mounting plate 3. As the robot falls, it will press the sliding contact plate 7 to move downward. The downward movement of the sliding contact plate 7 is controlled by the sliding block 81 to move the moving limit plate 82, the connecting plate 10 and the sealing block 9 downward. At the same time as the moving limit plate 82 moves downward, the connecting column 84 moves along the guide hole 85.

[0064] During the downward movement of the sliding contact plate 7 and the first extension plate 121, the sliding tooth 135 is controlled to move downward. When the sliding tooth 135 passes the pressing tooth 137, the elastic force of the elastic telescopic rod 132 controls the sliding tooth 135 and the striking rod 136 to quickly reset, so that the striking rod 136 acts on the positioning plate 134. The vibration is transmitted to the mounting plate 3 through the positioning plate 134. During the downward movement of the connecting plate 10, the moving plate 1504 is pressed to move downward. When the moving plate 1504 moves, the pressing plate 1502 is controlled to move downward through the vertical rod 1503. The pressing plate 1502 presses the gas in the air storage frame 1501 to be discharged, so that the downward movement of the moving plate 1504 is buffered. At the same time, the first spring 123 and the second spring 144 are stretched, so that the process of the robot moving downward to contact the mounting plate 3 is buffered and there will be no violent impact.

[0065] The gas in the gas storage box 1501 is compressed and discharged through the gas outlet valve 1507 and the connecting pipe 1508. The first air blowing head 1510 blows the gas quickly and at an angle into the threaded mounting hole 4 to clean the debris and dust on the inner wall of the threaded mounting hole 4. The second air blowing head 1513 blows the gas onto the upper surface of the mounting plate 3 so that the dust and debris can fall smoothly through the drop hole 6 onto the connecting plate 10 or fall to a position outside the mounting plate 3.

[0066] The combined action of vibration and air blowing allows the debris adhering to the threaded mounting hole 4 and mounting plate 3 to be easily detached and cleaned. When the connecting column 84 moves to the inclined section of the guide hole 85, the moving limit plate 82 separates from the limit groove 11. At this time, the second spring 144 controls the connecting plate 10 and the sealing block 9 to move upward and reset. The sealing block 9 moves into the drop hole 6. The third spring 1505 controls the squeezing plate 1502, the vertical rod 1503 and the moving plate 1504 to reset upward. The squeezing plate 1502 draws external gas into the air storage frame 1501 through the air inlet valve 1506.

[0067] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
