Description

Technical Field

[0001] The present invention relates to the technical field of automated robotic arms, and in particular to an automated robotic arm used for assembling and producing low-voltage distribution cabinets. Background Art

[0002] A low-voltage distribution cabinet is a type of power distribution equipment used in power systems operating at 50Hz (or 60Hz) AC and rated at 380V or less. Its primary function is to distribute, control, protect, and monitor electrical energy. It transmits power from the low-voltage grid to various electrical devices (such as motors, lighting, and air conditioners). In the event of circuit faults such as overload, short circuit, or leakage, internal switches, fuses, and other components cut off power to ensure electrical safety. During the production process, the cabinet components are assembled using screws.

[0003] However, the screws used in the existing distribution cabinet assembly have different specifications and sizes. When the existing assembly robot uses an electric screwdriver to tighten the screws to fix the distribution cabinet, on the one hand, it is inconvenient to adjust the mechanical torque according to the specifications of the screw. If the screwdriver head continues to rotate after the screw is driven in, it is easy to exceed the bearing limit of the screw and cause the screw head groove to be "screwed out", resulting in stripped threads. On the other hand, when the screwdriver is assembled after the screw is adsorbed, the rotation of the adsorbed screw may cause the screw to deviate, resulting in tilted friction between the screwdriver head and the screw head, causing the screw groove to be worn flat, resulting in stripped threads.

[0004] In response to the above problems, it is urgent to carry out innovative design based on the original automated robot arm for assembling and producing low-voltage distribution cabinets. Summary of the Invention

The pulling plate 75 slides vertically within the sliding groove opened on the surface of the sleeve 74, and a second spring is fixedly connected to the top of the sliding groove opened on the surface of the sleeve 74. The other end of the second spring is connected to the pulling plate 75, and a clamping block 76 is provided at the bottom of the pulling plate 75.

And locking sill 75 is located in the position that bolt 71 is in. And locking sill 75 is located in the position that bolt 71 is in.

[0032] As an embodiment of the present invention, the switching assembly includes a first ratchet 771 rotatably connected to the middle chamber of the first drive disk 4, the first ratchet 771 is driven by a drive motor installed at the top of the device shell 3, a first pawl 772 is provided on the periphery of the first ratchet 771, and the first pawl 772 is rotatably connected to the bottom of the middle chamber of the first drive disk 4 through a torsion spring, a second ratchet 773 is rotatably connected to the middle chamber of the second drive disk 71, a second pawl 774 is provided on the periphery of the second ratchet 773, and the second pawl 774 is rotatably connected to the bottom of the middle chamber of the first drive disk 4 through a torsion spring, and the first ratchet 773 is rotatably connected to the middle chamber of the second drive disk 4. The bottom of 71 is connected to the top of the second ratchet 773 through a connecting rod, and the first electromagnet 775 is installed on the inner wall of the cavity in the middle of the first drive disk 4 and the second drive disk 71 at the position corresponding to the second pawl 774. After a set of screws are tightened, the robot arm 2 is controlled to drive the device shell 3 to move to the screw box. At this time, the first electromagnet 775 on the inner wall of the cavity of the first drive disk 4 absorbs the first pawl 772, causing it to disengage from the tooth surface of the first ratchet 771. The first electromagnet 775 on the inner wall of the cavity of the second drive disk 71 is powered off and loses its magnetism, so that the second pawl 774 is again in contact with the tooth surface of the second ratchet 773 under the action of the torsion spring.

[0033] Working principle: When using the automated robotic arm for assembly and production using the low-voltage distribution cabinet, first control the robotic arm 2 to drive the device shell 3 to move to the part to be assembled, and then start the drive motor to drive the first ratchet 771 to rotate. The rotation of the first ratchet 771 cooperates with the first pawl 772 to drive the first drive disk 4 to rotate. At the same time, the first electromagnet 775 on the inner wall of the cavity of the second drive disk 71 adsorbs the second pawl 774, causing it to disengage from the tooth surface of the second ratchet 773. At this time, when the first ratchet 771 rotates, it will not drive the second drive disk 71 to rotate. At the same time, the electric telescopic rod 67 is extended and retracted according to the size of the screw to increase or decrease the contact area with the clamping block 66. Then the first drive disk 4 rotates to drive the gear 5 to rotate, and the rotation of the gear 5 drives the first rotating block 61 to rotate. The rotation of the first rotating block 61 drives the first turntable 62 to rotate, and the rotation of the first turntable 62 cooperates with its surface The arc-shaped slide groove on the surface drives the electric telescopic rod 67 to retract inwardly along the straight groove on the surface of the second rotary disk 64 until the corresponding pressing block 66 is clamped, so that the pressing block 66 retracts inwardly to clamp the screwdriver head 65. At this time, the second electromagnet 10 is started, and the first rotating block 61 and the second rotating block 63 are attracted to each other, so that they rotate synchronously, thereby driving the pressing block 66 to rotate circumferentially along the inner periphery of the limit plate 8 through the telescopic member 9. While the pressing block 66 rotates circumferentially, it drives the screwdriver head 65 to rotate under the action of friction, thereby driving the screw into the part to be assembled. As the screw is driven in, the clamping block 76 moves toward the periphery under the action of the resistance at the bottom of the sleeve 74 until it disengages from the screw. After the screw is driven in, the screwdriver head 65 will automatically stop rotating due to insufficient friction of the top pressing block 66, preventing the screwdriver head 65 from continuing to rotate after the screw is driven in, causing the screw head to form a slipped thread;

[0034] After finishing a set of screws, the control robot arm 2 drives the device shell 3 to move to the screw box. At this time, the first electromagnet 775 on the inner wall of the cavity of the first driving disk 4 attracts the first pawl 772, causing it to disengage from the tooth surface of the first ratchet 771. The first electromagnet 775 on the inner wall of the cavity of the second driving disk 71 is powered off and loses its magnetism, so that the second pawl 774 contacts the tooth surface of the second ratchet 773 again under the action of the torsion spring. Then the driving motor rotates to drive the first ratchet 771 to rotate, the first ratchet 771 rotates to drive the second ratchet 773 to rotate, the second ratchet 773 rotates to drive the second driving disk 71 to rotate, and the second driving disk 71 rotates. The rotation drives the rotating rod 72 to rotate, and the rotation of the rotating rod 72 cooperates with the protrusion 12 on the movable plate 73 to slide in the guide groove 11, driving the movable plate 73 to move upward. The upward movement of the movable plate 73 drives the pulling plate 75 at its bottom to move upward. The upward movement of the pulling plate 75 drives the clamping block 76 to move upward, driving the clamping block 76 to move upward and open to the periphery under the resistance of the bottom of the sleeve 74. After the screwdriver head 65 absorbs the screw, the movable plate 73 moves downward along the sliding groove on the surface of the rotating rod 72 under the action of the second spring to reset, fixing the screw position to prevent the screw from shifting during rotation.
