Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a wall-mounted device for protecting robotic arms. Background Technology

[0002] In the manufacturing process of rotary dehumidifiers, polyurethane foam panels are commonly used as the insulation shell for their housings. After being fully foamed and molded, these panels are heavy and bulky. Their handling, positioning, and assembly on flexible assembly lines are key aspects of the production process. To address this challenge, modern flexible assembly lines widely use robotic arms as the core lifting assistance device to help operators efficiently and accurately complete the assembly of heavy panels.

[0003] Existing assembly lines generally lack dedicated robotic arms for wall mounting. Whether during workstation breaks or production line pauses, the robotic arms and their heavy end-effectors are left unsecured and unrestrained, or placed haphazardly. This disorder not only occupies valuable space in dense production lines, but also poses a high risk of accidental collisions between the robotic arms and surrounding precision equipment during normal operation.

[0004] Therefore, to address the specific challenges posed by the assembly of heavy panels, there is an urgent need in the field for a dedicated robotic arm mounting wall. This wall should provide a safe and standardized parking area for the robotic arm, ensuring its reliable fixation when not in operation and fundamentally eliminating the risk of falling after gas supply is interrupted. Simultaneously, the wall should also possess protective functions to systematically reduce the risk of collisions that may occur during the robotic arm's parking and operation, ensuring the safe, stable, and efficient assembly and production of rotary dehumidifiers. In this regard, the present invention provides a robotic arm protective mounting wall. Utility Model Content

[0005] The purpose of this application is to provide a wall-mounted protective device for robotic arms to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a protective wall hanging for a robotic arm, comprising a column and a U-shaped mounting plate fixedly installed on the column, wherein a triangular wall hanging is welded and fixedly installed on the U-shaped mounting plate, and a buffer assembly is provided on the side of the U-shaped mounting plate near the triangular wall hanging. The buffer assembly is used to protect the robotic arm from collisions, and the buffer assembly includes a U-shaped buffer plate, a buffer base, and a buffer block. The triangular wall-mounted structure has a flip-over protective assembly at the end furthest from the column. This assembly is used to limit and protect the robotic arm on the triangular wall-mounted structure. The flip-over protective assembly includes a fixed base plate, connecting rods, and a protective baffle. The fixed base plate is fixedly installed at the end of the triangular wall-mounted structure furthest from the column. A connecting block is fixedly installed at the top of the fixed base plate at the end furthest from the column. The connecting rods are movably connected to both ends of the connecting block via pivots. The protective baffle is movably connected to the flip-over block via pivots. A fixed frame is fixedly installed at the bottom of the fixed base plate. The fixed frame is internally connected to the center of the bottom of the flip-over block via a hydraulic telescopic rod.

[0007] Preferably, a plurality of buffer bases are fixedly installed on the top side of the U-shaped mounting plate near the triangular wall. Buffer springs are fixedly installed around the inner bottom of each buffer base by bolts. Buffer blocks are fixedly installed on the top of each buffer spring and are fixedly installed on the U-shaped buffer plate.

[0008] Preferably, a damping telescopic rod is fixedly installed at the center of the inner bottom of the buffer base, and the top end of the damping telescopic rod is fixedly installed on the buffer block, and the buffer block is movable at the top of the buffer base.

[0009] Preferably, a rubber protective pad is fixed to the top of the triangular wall hanging by bolts.

[0010] Preferably, the hydraulic telescopic rod is fixedly installed on the inner bottom of the fixed frame by bolts, and the top of the fixed base plate has an movable hole, and the top of the hydraulic telescopic rod moves through the movable hole.

[0011] Preferably, a rubber buffer pad is fixedly installed on the top of the fixed base plate by screws, and the buffer pad provides protective support for the side of the robot arm. A battery pack is fixedly installed on the bottom of the fixed base plate near the column by bolts.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. In this utility model, the buffer assembly consisting of a U-shaped buffer plate, a buffer spring, and a damping telescopic rod, located on the side of the U-shaped mounting plate, effectively absorbs and dissipates the impact energy of lateral swaying or accidental collisions generated by the robotic arm when it is working normally as an assist device. This avoids hard contact between the robotic arm and the rigid hanging structure, greatly reduces the risk of equipment damage due to collisions, and extends the service life of the robotic arm and the wall-mounted structure. 2. In this utility model, the combination of a triangular hanging wall and a tilting protective assembly driven by a hydraulic telescopic rod provides a clear and controlled parking position for the robotic arm when the gas supply is interrupted, during maintenance, or in standby mode. The physical barrier formed by the vertical protective baffle reliably prevents the robotic arm from slipping off the end of the hanging arm due to its own weight or accidental movement, completely solving the safety hazards of the robotic arm falling or shifting after power failure, and ensuring the safety of equipment and personnel. 3. In this utility model, the dual protection design of side buffer and limit of robotic arm effectively reduces the risk of collision, and plans and creates a safe parking area for robotic arm. The side buffer component deals with lateral risks, and the end flip protection component deals with longitudinal risks. This not only reduces the risk of collision between the robotic arm and itself and the wall, but also reduces the risk of interference with other surrounding equipment. At the same time, the clear parking position makes the on-site equipment management more standardized and orderly, and optimizes the layout of the workspace. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Reference Figures 1-6 The wall hanging for protecting a robotic arm shown includes a column 10 and a U-shaped mounting plate 11 fixedly installed on the column 10. A triangular wall hanging 12 is welded and fixedly installed on the U-shaped mounting plate 11. A buffer assembly is provided on the side of the U-shaped mounting plate 11 near the triangular wall hanging 12. The buffer assembly is used to protect the robotic arm from collisions. The buffer assembly includes a U-shaped buffer plate 20, a buffer base 21, and a buffer block 22. When the robotic arm moves or unexpectedly stops breathing, it may swing sideways. At this time, the arm will hit the U-shaped buffer plate 20 installed on the U-shaped mounting plate 11. The impact force is transmitted to the buffer block 22 through the buffer plate. The buffer block 22 compresses the buffer spring 23 and pushes the damping telescopic rod 24 to contract. The spring absorbs most of the impact energy through elastic deformation, while the damping telescopic rod 24 dissipates energy by using the damping effect, transforming the violent collision into a soft, attenuated buffering motion, thereby protecting the robotic arm and the wall-mounted structure and significantly reducing the risk of collision.

[0018] The triangular wall-mounted 12 is equipped with a flip-over protection component at the end away from the column 10. The flip-over protection component is used to limit and protect the robot arm on the triangular wall-mounted 12. The flip-over protection component includes a fixed base plate 30, a connecting rod 32, and a protective baffle 33. The fixed base plate 30 is fixedly installed on the end of the triangular wall-mounted 12 away from the column 10 by bolts. A connecting block 31 is fixedly installed on the top of the fixed base plate 30 at the end away from the column 10 by bolts. The two ends of the connecting block 31 are movably connected to the connecting rod 32 by a rotating shaft. The top ends of the connecting rod 32 are movably connected to the protective baffle 33 by a rotating shaft. The protective baffle 33 is movably connected to the flip-over block 34. A fixed frame 35 is fixedly installed on the bottom of the fixed base plate 30 by bolts. The fixed frame 35 is connected to the bottom center of the flip-over block 34 by a hydraulic telescopic rod 36.

[0019] Activating the flip protection assembly: The hydraulic telescopic rod 36 retracts under the power supply of the battery pack 39, pulling the flip block 34 downward. Since the flip block 34 is movably connected to the protective baffle 33, and the two ends of the protective baffle 33 are hinged to the connecting block 31 through the connecting rod 32, this thrust forces the protective baffle 33 to flip from a horizontal state to a vertical state around the hinge axis, forming a solid physical barrier at the end of the triangular hanging wall 11. This barrier provides a clear stopping area for the robotic arm, effectively preventing the robotic arm from sliding down under its own weight or slipping off the end under various conditions, including after the gas supply stops or due to accidental movement, thus achieving reliable fixation.

[0020] See Figures 1-6 A number of buffer bases 21 are bolted to the top of the U-shaped mounting plate 11 near the triangular wall 12. Buffer springs 23 are bolted to the bottom of the buffer bases 21. Buffer blocks 22 are bolted to the top of the buffer springs 23. The buffer blocks 22 are fixed to the U-shaped buffer plate 20. A damping telescopic rod 24 is bolted to the center of the bottom of the buffer bases 21. The top of the damping telescopic rod 24 is fixed to the buffer block 22. The buffer block 22 is movable at the top of the buffer bases 21. There are four sets of buffer bases 21. A rubber protective pad 13 is bolted to the top of the triangular wall 12 to support and protect the bottom of the robotic arm.

[0021] See Figures 1-6 A hydraulic telescopic rod 36 is bolted to the inner bottom of the fixed frame 35. A movable hole 37 is provided on the top of the fixed base plate 30, and the top of the hydraulic telescopic rod 36 moves through the movable hole 37. A rubber buffer pad 38 is bolted to the top of the fixed base plate 30, and the buffer pad 38 provides protective support for the side of the robot arm. A battery pack 39 is bolted to the bottom of the fixed base plate 30 on the side near the column 10, and the battery pack 39 provides power to the hydraulic telescopic rod 36. An oil supply mechanism is also provided, which is existing technology and will not be described in detail here.

[0022] The working principle of this utility model is as follows: When the robot arm moves or sways unexpectedly in the horizontal direction, its arm or end effector will first come into contact with the U-shaped buffer plate 20 installed on the U-shaped mounting plate 11. After being impacted, the U-shaped buffer plate 20 transmits the impact force to the buffer block 22 at its bottom. The buffer block 22 then compresses the buffer spring 23 in the buffer base 21. At the same time, the damping telescopic rod 24 retracts, using its internal damping effect to absorb and dissipate the impact energy. Through the elastic deformation of the spring and the energy dissipation of the damping rod, the violent collision impact is transformed into a gentle buffering motion, effectively avoiding hard collisions between the robot arm and the rigid wall structure, thereby protecting the robot arm body and the wall structure from damage. When the robotic arm needs to be parked at the end of the triangular wall 12 for maintenance or standby, the flip protection assembly is activated. The hydraulic telescopic rod 36 retracts under the power of the battery pack 39, and its top pushes the flip block 34 downward. Since the flip block 34 is movably connected to the protective baffle 33, and the two ends of the protective baffle 33 are hinged to the connecting block 31 fixed on the fixed base plate 30 through the connecting rod 32, this downward pull forces the protective baffle 33 to flip upward around the hinge points at both ends, and finally stand up from the flat position to form a protective barrier perpendicular to the plane of the fixed base plate 30. This upright protective baffle 33 can effectively prevent the robotic arm from accidentally slipping off the end of the triangular wall 11. When the robotic arm needs to be removed, the hydraulic telescopic rod 36 rises, pulling the flip block 34 and the protective baffle 33 upward to restore them to the flat position, making room for operation. The whole process is smooth and reliable.

[0023] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
