At the same time, the calibration mechanism 5 performs position calibration of the locking gripper 2, quickly completing the detection and calibration actions to ensure the accuracy of the subsequent screw-fastening by the locking gripper 2.

[0035] In one embodiment of this utility model, the detection hole 42 is disposed on the outer side wall of the detection platform 41, the detection probe 43 is disposed on the detection hole 42, the detection platform 41 is disposed on the support frame 44, the support frame 44 is provided with a plurality of pushing components, the plurality of pushing components are arranged to form a circumference, the detection platform 41 is disposed at the center of the circumference, and the pushing components are used to press the screws gripped by the locking gripper 2 against the detection platform 41.

[0036] In one embodiment of the present invention, the pushing component includes a pushing frame, on which a pushing cylinder 45 is provided. The pushing cylinder 45 is driven to push a pushing block 46. The pushing block 46 is provided with a pushing groove that matches the detection table 41.

[0037] Specifically, the robotic arm 1 moves the locking gripper 2, which holds a screw, to the screw removal mechanism 4. The screw on the locking gripper 2 passes through the detection hole 42 and connects to the detection probe 43.

[0042] In one embodiment of this utility model, the feeding mechanism 3 includes a vibratory feeder 31 and a receiving tray 36.

The feeding track 32 conveys the screws transmitted by the vibratory feeder 31 one by one into the receiving holes 37.

[0043] Specifically, the vibratory feeder 31 conveys screws one by one to the feeding track 32, which then transmits the screws one by one. The feeding motor 35 drives the receiving plate 36 to rotate, so that the receiving hole 37 is positioned opposite to the discharge end 33 of the feeding track 32. This allows the screws conveyed by the vibratory feeder 31 to be transmitted one by one into the receiving hole 37, completing the feeding of multiple screws simultaneously. Feeding multiple screws allows the screw-driving assembly operation to be carried out continuously, effectively saving time and improving production efficiency.

[0044] In one embodiment of this utility model, the locking gripper 2 includes a mounting frame 21, on which a lifting cylinder 22 is provided. The lifting cylinder 22 is drivenly connected to a lifting frame 23. The lifting frame 23 is slidably mounted on the mounting frame 21. An electric screwdriver 24 is provided on the lifting frame 23. A plurality of suction rods 26 are provided on the mounting frame 21. The suction rods 26 are correspondingly arranged with the electric screwdriver 24. The lifting cylinder 22 drives the electric screwdriver 24 to pass through the suction rods 26 to perform a screw-locking operation on the screws picked up by the suction rods 26.

[0045] Specifically, the lifting cylinder 22 drives the electric screwdriver 24 to pass through the suction rod 26 to tighten the screws picked up by the suction rod 26. This process is highly automated and greatly improves work efficiency.

[0046] In one embodiment of this utility model, the number of electric screwdrivers 24 is one, a turntable 27 is provided on the mounting frame 21, a plurality of suction rods 26 are evenly arranged around the turntable 27, and a mounting motor 292 is provided on the mounting frame 21. The mounting motor 292 is driven and connected to the turntable 27. The mounting motor 292 drives the turntable 27 to rotate so that the suction rods 26 on it are arranged one by one corresponding to the electric screwdrivers 24.

[0047] Specifically, the installation motor 292 drives the turntable 27 to rotate, so that the suction rods 26 on it are successively aligned with the electric screwdrivers 24. That is, the lifting cylinder 22 drives the electric screwdrivers 24 to pass through the suction rods 26 to tighten the screws picked up by the suction rods 26. The installation motor 292 drives the turntable 27 to rotate, so that another suction rod 26 with a screw is aligned with the electric screwdriver 24. The lifting cylinder 22 again drives the electric screwdrivers 24 to pass through the suction rods 26 to tighten the screws. This cycle is repeated to complete the screw tightening process on all the suction rods 26. The automation level is high and the work efficiency is greatly improved.

[0048] In one embodiment of this utility model, a guide tube 28 is slidably mounted on the suction rod 26. A limit block is provided on the guide tube 28 to prevent the guide tube 28 from detaching from the suction rod 26. A guide hole 29 matching the bit 35 of the electric screwdriver 24 is provided on the guide tube 28. A spring 291 is sleeved on the guide tube 28. One end of the spring 291 abuts against the suction rod 26, and the other end abuts against the guide tube 28.

[0049] Specifically, the bit 35 of the electric screwdriver 24 passes through the guide hole 29, and the guide tube 28 slides along the suction rod 26 to guide its movement, ensuring the moving accuracy of the bit 35 of the electric screwdriver 24 and the subsequent screw-driving accuracy, resulting in a high screw-driving accuracy rate. At the same time, a limit block is set on the guide tube 28 to prevent the guide tube 28 from detaching from the suction rod 26. A spring 291 is sleeved on the guide tube 28. Under the reaction action of the spring 291, the guide tube 28 and the electric screwdriver 24 can move up and down synchronously, preventing the electric screwdriver 24 from deviating. Thus, during the screw-driving process, the bit 35 of the electric screwdriver 24 is always perpendicular to the screw hole, preventing the screw from being driven off-center and causing damage to the screw hole, further ensuring the screw-driving accuracy.

[0050] In one embodiment of this utility model, the calibration mechanism 5 includes a fixed base 52, which is mounted on a machine base 51. A plurality of detection frames 53 are evenly arranged on the fixed base 52, and detection sensors 54 are mounted on the detection frames 53. The fixed base 52 is provided with a reference hole 55 that matches the bit 35 of the electric screwdriver 24. The bit 35 of the electric screwdriver 24 is centered and positioned by the plurality of detection sensors 54.

[0051] Specifically, the mounting base 52 is provided with a reference hole 55 that matches the bit 35 of the electric screwdriver 24. Multiple detection sensors 54 are used to center and position the bit 35 of the electric screwdriver 24. The detection sensors 54 detect whether the rotating bit 35 is wobbling to determine whether the bit 35 is skewed. The accuracy is high and the detection and correction actions are completed quickly to ensure the accuracy of the bit 35 of the electric screwdriver 24 when screwing screws.

[0052] Usage process

[0053] The vibratory feeder 31 feeds screws one by one onto the feeding track 32, which then transmits the screws one by one. The feeding motor 35 drives the receiving plate 36 to rotate, so that the receiving hole 37 is positioned opposite to the discharge end 33 of the feeding track 32, allowing the screws fed by the vibratory feeder 31 to be transmitted one by one into the receiving hole 37, simultaneously completing the feeding of multiple screws. The robotic arm 1 moves the locking gripper 2 to the receiving plate 36, and multiple suction rods 26 on the turntable 27 simultaneously grasp the screws on the receiving plate 36. The suction rods 26 pick up the screws by magnetic attraction or vacuum suction, which is existing technology. The robotic arm 1 moves the locking gripper 2, which is holding screws, to the screw removal mechanism 4. The screws on the locking gripper 2 are passed through the detection hole 42 and connected to the detection probe 43. When one or more detection probes 43 do not detect a screw, the push cylinder... The pusher 46, driven by cylinder 45, presses the screw onto the detection hole 42 of the detection table 41. After the pusher 46 loosens the screw, it falls onto the inclined plate in the receiving space 61. The inclined plate is connected to the discharge port 62. The screw is collected by the receiving box 63 along the discharge port 62. At the same time, the robot 1 drives the locking gripper 2 to grab the screw again. Conversely, the robot 1 drives the locking gripper 2 to move to the screw-on position on the display panel. The lifting cylinder 22 drives the electric screwdriver 24 to pass through the suction rod 26 to perform the screw-on operation. The motor 292 drives the turntable 27 to rotate, so that another suction rod 26 with a screw is positioned corresponding to the electric screwdriver 24. The lifting cylinder 22 drives the electric screwdriver 24 to pass through the suction rod 26 to perform the screw-on operation. This cycle is repeated to complete the screw-on processing on all suction rods 26.
