Specific implementation mode

[0017] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0018] As Figures 1-4 shown, a vision detection device for full inspection of rivets on sheet metal parts includes a chassis 1, a conveyor belt 2 is arranged on the chassis 1, and a bracket 3 is arranged on the chassis 1. An annular guide rail 5 is fixed on the lower surface of an annular frame 4 on the bracket 3, and a rotating frame 6 is connected to the annular guide rail 5 through a slider 7. A first servo motor 8 is arranged on the bracket 3. A guide rod 9 and a lead screw 10 are arranged on the rotating frame 6, and a second servo motor 11 connected to the lead screw 10 is arranged at the end of the rotating frame 6. A movable seat 12 is arranged on the guide rod 9 and the lead screw 10, and a vision camera 15 is arranged in a square hole 14 on the movable seat 12 through a mounting structure 13. A drive motor 18 is arranged on the chassis 1, and a roller sleeving the conveyor belt 2 is installed on the chassis 1. A transmission component 19 connected to the drive motor 18 is arranged on one of the rollers. The transmission component 19 includes transmission wheels and a chain. The two transmission wheels are respectively installed on the roller and the drive motor 18, and the chain is sleeved on the transmission wheels. The output shaft of the first servo motor 8 is connected to the rotating frame 6. A round hole 16 and a threaded hole 17 are arranged on the movable seat 12. The guide rod 9 passes through the round hole 16, and the lead screw 10 is threadedly connected to the threaded hole 17. The position of the vision camera 15 is adjusted by means of mechanical drive, which improves the use flexibility and adjustment accuracy. By adopting structures such as the second servo motor 11 and the lead screw 10, while ensuring the rapid adjustment of the position of the movable seat 12, the stability after adjustment can be guaranteed. The rotating frame 6 can rotate on the annular guide rail 5 through the slider 7, further improving the adjustment flexibility of the vision camera 15.

[0019] When visually inspecting the rivets of sheet metal parts, start the drive motor 18 on the chassis 1. The corresponding transmission wheel of the drive motor 18 drives the chain to move, thereby driving the roller to rotate through the transmission wheel at the end of the roller. The conveyor belt 2 rotates together, and the sheet metal part is placed on the conveyor belt 2. The conveyor belt 2 conveys the sheet metal part. When the sheet metal part passes under the bracket 3, the vision camera 15 installed in the square hole 14 through the mounting structure 13 operates to visually inspect the sheet metal part. The inspection result is fed back to the computer, and data analysis is performed based on the fed-back result to finally obtain the corresponding data of the rivets of the sheet metal part. When using the device, the relative position of the vision camera 15 can be adjusted. During adjustment, start the second servo motor 11 on the rotating frame 6. The second servo motor 11 drives the movable seat 12 to move through the lead screw 10 and the threaded hole 17. The movable seat 12 then moves along the guide rod 9 through the round hole 16, thereby driving the vision camera 15 to move to a suitable position and then it can be used. For the annular sheet metal part, after adjusting the position of the vision camera 15, the first servo motor 8 can also be started. The rotating frame 6 rotates on the annular guide rail 5 through the slider 7 under force, thereby performing circumferential inspection on the sheet metal part, improving the inspection flexibility and adaptability. When needed, the vision camera 15 can be quickly disassembled through the mounting structure 13, facilitating the maintenance and replacement work.

[0020] Through the above implementation scheme, the mounting structure 13 includes a clamping block 1301, a mounting frame 1302, a pressing plate 1303 and a movable rod 1304. The clamping block 1301 is fixed in the square hole 14. The mounting frame 1302 is installed on the vision camera 15, and one end of the mounting frame 1302 is clamped on the clamping block 1301. The pressing plate 1303 is fixedly connected to the movable rod 1304, and the movable rod 1304 passes through the movable seat 12. The pressing plate 1303 abuts against the groove in the mounting frame 1302. The mounting structure 13 further includes a pressing spring 1305, a tapered screw hole 1306 and a fastening limit bolt 1307. The pressing spring 1305 is sleeved on the movable rod 1304, and the end parts of the pressing spring 1305 respectively contact the inner wall of the square hole 14 and the pressing plate 1303. A cross deep groove is provided at the end of the movable rod 1304. The tapered screw hole 1306 is opened at the end of the movable rod 1304 and communicates with the cross deep groove. The fastening limit bolt 1307 is threadedly connected in the tapered screw hole 1306. The vision camera 15 is arranged on the movable seat 12 through the mounting structure 13. By using the clamping effect of the clamping block 1301 and the mounting frame 1302, and cooperating with the pressing action of the pressing plate 1303, the installation and disassembly of the vision camera 15 can be quickly realized, and the operation convenience is high. The movable rod 1304 plays a guiding role. At the same time, a fastening limit bolt 1307 is arranged in the tapered screw hole 1306 at the end of the movable rod 1304, which plays a limiting role during adjustment and has the effect of expanding the movable rod 1304 for fixation during use.

[0021] When installing the vision camera 15, the vision camera 15 and the mounting bracket 1302 are fixed together. By tightening the limit bolt 1307, the movable rod 1304 is pulled outwards, and the abutting plate 1303 moves together and compresses the abutting spring 1305. After the abutting plate 1303 gives way, the vision camera 15 is set into the square hole 14, so that one end of the mounting bracket 1302 is clamped onto the clamping block 1301. Then, after loosening the tightening limit bolt 1307, under the action of the abutting spring 1305, the abutting plate 1303 moves and abuts against the groove on the mounting bracket 1302, thus completing the fixation of the vision camera 15. Subsequently, the tightening limit bolt 1307 is rotated. The tightening limit bolt 1307 rotates and moves in the tapered screw hole 1306, so that the end of the movable rod 1304 deforms through the cross deep groove, thereby increasing the diameter of the end of the movable rod 1304, making the movable rod 1304 fixed to the movable seat 12, and further ensuring the stability of the vision camera 15 during subsequent use. If it is necessary to disassemble the vision camera 15, after the tightening limit bolt 1307 is externally rotated, the movable rod 1304 can move on the movable seat 12. Pull the movable rod 1304 to make the abutting plate 1303 give way, and then the vision camera 15 can be disassembled.
