[0024] Embodiment 1

[0025] like Figure 1-4 As shown, a smart wheel hub protective cover grabbing system includes a wheel hub support rod 2 located above a conveyor line 1, a wheel hub 16 is provided on the wheel hub support rod 2, and a protective cover 17 is provided at a through hole in the center of the top of the wheel hub 16. The protective cover 17 includes a protective cover body 19 and a protective cover handle 20, both of which are cylindrical, and the protective cover handle 20 is provided at the center of the top of the protective cover body 19.

[0026] The hub support rods 2 on the conveyor line 1 are spaced a certain distance apart to convey the hub 16 with the protective cover 17 forward. The side of the robot base 3 on one side of the conveyor line 1 is provided with a centering mechanism 4 close to the hub support rods 2.

[0027] like Figure 5 As shown, the holding mechanism 4 includes a holding cylinder fixing part, a 180° holding cylinder 13, a holding block fixing part, and a V-shaped holding block 14. One end of the holding cylinder fixing part is connected to the robot base 3, and the other end is connected to the 180° holding cylinder 13. Figure 6As shown, the end of the 180° clamping cylinder 13 is connected to the V-shaped clamping block 14 through the clamping block fixing piece. When the hub support rod 2 stops the hub 16 with the protective cover 17 at a specific position, the signal detection determines the position of the hub 16, and then the cylinder of the V-shaped clamping block 14 is actuated, so that the clamping head of the V-shaped clamping block 14 holds the hub support rod 2 and fixes the position of the hub 16.

[0028] The top of the robot base 3 is connected to the robot 5, and a transition flange 6 is provided at one end of the robot 5 away from the robot base 3. Figure 7 As shown, one end of the transition flange 6 is connected to the camera 7, and the other end thereof is connected to the fixture 8. A clamping finger 9 is provided below the parallel cylinder 15 below the fixture 8, as shown in FIG. Figure 8 As shown, a sawtooth groove 18 is provided inside the clamp finger 9, and the sawtooth groove 18 can prevent the protective cover 17 from falling from the clamp finger 9 when the robot 5 grasps the protective cover handle 20. When the position of the wheel hub 16 is fixed, the camera 7 automatically takes pictures to determine the XYZ coordinates of the protective cover 17 in the center of the wheel hub 16, and then determines the position of the protective cover handle 20. The system transmits the coordinate position of the central protective cover handle 20 to the robot 5, and the robot 5 moves to drive the clamp 8 to grasp the protective cover handle 20.

[0029] A slideway 10 is provided on the side of the robot base 3 away from the conveyor line 1, and one end of the slideway 10 away from the robot base 3 is connected to the receiving box.

[0030] A robot fence 11 is set outside the activity area of ​​the robot 5, and the robot fence 11 can prevent the device from being interfered with by the outside world during operation. A control cabinet 12 is set outside the robot fence 11, and a start-stop switch is set on the control cabinet 12. The conveyor line 1, the centering mechanism 4, and the robot 5 are all electrically connected to the control cabinet 12. When there is an abnormal situation, the worker can press the stop switch at any time. After eliminating the abnormality, directly press the start switch, and the equipment will continue the unfinished process last time.

[0031] The specific process flow in the embodiment is as follows:

[0032] 1) The hub support rod conveys the hub with protective cover on the conveyor line;

[0033] 2) The hub support rod stops at a specific position, and the signal detection determines the position of the hub;

[0034] 3) The V-shaped clamping block cylinder in the clamping mechanism moves to hold the hub support rod to fix the hub position;

[0035] 4) The visual camera takes a picture to determine the XYZ coordinates of the protective cover handle in the center of the wheel hub;

[0036] 5) The robot moves according to the position sent by the visual camera, driving the fixture to grab the protective cover handle;

[0037] 6) The robot drives the fixture to the slide position, opens the fixture, and releases the protective cover;

[0038] 7) The protective cover falls into a slide with a certain slope and slides into the receiving box;

[0039] 8) Repeat steps 1)-7) to achieve continuous production.

[0040] Therefore, the utility model adopts the above-mentioned intelligent wheel hub protective cover grabbing system, through the logic control of PLC, using a robot to intelligently and automatically take the cover, which can reduce manual workload, reduce labor intensity, and improve production efficiency.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
