In this embodiment, the first drive mechanism 13 is preferably a cylinder, and the second drive mechanism 14 is preferably a motor.

[0051] Furthermore, such as Figure 2 As shown, the working end of the robotic arm 11 is equipped with a gripping head 111, which is replaceable and is used to grip bottle caps.

[0052] Furthermore, such as Figure 2As shown, the first detection module 2 includes: a bottle cap holder 21 and an arc generator 22; the bottle cap holder 21 holds a bottle cap; the arc generator 22 is arranged adjacent to the bottle cap holder 21, and the arc generator 22 detects the airtightness of the bottle cap on the bottle cap holder 21.

[0053] Furthermore, such as Figures 1-3 As shown, the second detection module 3 includes: a rotating device 31, a stretching device 32, a first blowing device 33, and a second blowing device 34; the rotating device 31 is arranged adjacent to the robot arm 11, and the robot arm 11 grabs the bottle caps that have been detected by the first detection module 2 and places them on the rotating device 31; the stretching device 32 is arranged adjacent to the rotating device 31, and the stretching device 32 detects the tension of the bottle caps on the rotating device 31; the first blowing device 33 is arranged adjacent to the rotating device 31, and the first blowing device 33 separates the bottle caps on the rotating device 31 after detecting the tension; the second blowing device 34 is arranged adjacent to the stretching device 32, and the second blowing device 34 separates the pull ring of the bottle caps on the stretching device 32 after detecting the tension.

[0054] Furthermore, such as Figure 4 As shown, the rotating device 31 includes: a rotating platform 311, a plurality of fixed seats 312, a plurality of clamping mechanisms 313, a rotating mechanism 314, and a flipping mechanism 315; the plurality of fixed seats 312 are distributed circumferentially along the rotating platform 311; the number of clamping mechanisms 313 corresponds one-to-one with the number of fixed seats 312, and each fixed seat 312 is provided with a clamping mechanism 313, which clamps the bottle cap placed on the fixed seat 312; the rotating mechanism 314 is connected to the rotating platform 311, and the rotating mechanism 314 drives the rotating platform 311 to rotate, thereby selecting and using different fixed seats 312 by rotating the rotating platform 311; the flipping mechanism 315 is connected to the rotating platform 311, and the flipping mechanism 315 drives the rotating platform 311 to flip, preferably a cylinder, which drives the rotating platform 311 to flip in the direction of cylinder extension and retraction through the extension and retraction of the cylinder. In this embodiment, the preferred flipping angle of the rotating platform 311 is 45 degrees, which is convenient for the hook 322 of the stretching device 32 to hook the pull ring of the bottle cap. In this embodiment, there are two fixing seats 312 and two clamping mechanisms 313. Different fixing seats 312 correspond to bottle caps of different sizes. Depending on the actual working conditions, multiple fixing seats 312 of different sizes can also be added to meet the needs of more different bottle caps.

[0055] Furthermore, such as Figure 3As shown, the stretching device 32 includes: a linear module 321, a hook 322, and a limiting member 323.

The limiting member 323 is connected to the hook 322, and the limiting member 323 prevents the pull ring hooked by the hook 322 from falling off. In this embodiment, the limiting member 323 is preferably a cylinder. When the hook 322 hooks the pull ring, the cylinder extends and abuts against the hook 322, so that the hooked pull ring will not fall off, which facilitates the detection of the pull force of the pull ring.

[0056] Furthermore, such as Figure 5 As shown, the recycling module 4 includes: a first recycling mechanism 41 and a second recycling mechanism 42; the first recycling mechanism 41 is connected to the first detection module 2, and the first recycling mechanism 41 recycles bottle caps that fail the airtightness test after being detected by the first detection module 2.

[0057] Furthermore, such as Figure 5 As shown, the second recycling mechanism 42 includes: a pair of bottle cap recycling bins 421 and a pair of pull ring recycling bins 422; the pair of bottle cap recycling bins 421 are both connected to the first air blowing device 33, and the pair of bottle cap recycling bins 421 respectively recycle qualified and unqualified bottle caps from the bottle caps separated by the first air blowing device 33; the pair of pull ring recycling bins 422 are both connected to the second air blowing device 34, and the pair of pull ring recycling bins 422 respectively recycle qualified and unqualified pull rings from the pull rings separated by the second air blowing device 34. In this embodiment, the second recycling mechanism 42 further includes: a pair of baffles (not shown in the figure) and a pair of rotating shafts 423. Each rotating shaft 423 is provided with a baffle. One rotating shaft 423 and a baffle are located at the connection between a pair of bottle cap recycling bins 421 and the first air blowing device 33; the other rotating shaft 423 and the other baffle are located at the connection between a pair of pull ring recycling bins 422 and the second air blowing device 34. When the rotating shaft 423 rotates, it drives the baffle to rotate, thereby classifying qualified and unqualified bottle caps and pull rings, so that qualified and unqualified bottle caps and pull rings enter different recycling bins for easy recycling.

[0058] In use, the holding plate 52 containing the bottle cap is placed on the holding position 51. The robotic arm 11 drives the camera 12 to identify the position of the bottle cap. After identification, the robotic arm 11 picks up the bottle cap and places it on the bottle cap holder 21. The airtightness of the bottle cap is tested by the arc generator 22. Bottle caps that fail the test are picked up by the robotic arm 11 and sent to the first recycling bin 411. Qualified bottle caps are picked up by the robotic arm 11 and placed on the fixed seat 312. The clamping mechanism 313 clamps the bottle cap. The rotating mechanism 314 drives the rotating table 311 to rotate, which drives the fixed seat 312 to rotate to the hook 322. The flipping mechanism 315 drives the rotating table 311 to rotate 45 degrees. The linear module 321 drives the hook 322 to move to the bottle cap on the fixed seat 312 and hooks the hook 322 on the bottle cap. The cylinder extends and presses against the hook 322. The linear module 321 then drives the hook 322 to move to test the pull ring tension. After the test is completed, the cylinder retracts, and at the same time, the second blowing device 34 blows air onto the hook 322, blowing the pull ring on the hook 322 down and into the pull ring recycling box 422. The rotating shaft 423 at the connection between the pull ring recycling box 422 and the second blowing device 34 rotates, causing the baffle to rotate and sorting the fallen pull rings into different pull ring recycling boxes 422. At this time, the rotating mechanism 314 rotates again, causing the bottle cap on the fixed seat 312 on the rotating table 311 to rotate to the first blowing device 33. The clamping mechanism 313 releases the bottle cap, and the first blowing device 33 blows the bottle cap down into the bottle cap recycling box 421. The rotating shaft 423 at the connection between the bottle cap recycling box 421 and the first blowing device 33 rotates, causing the baffle to rotate and sorting the fallen bottle caps into different bottle cap recycling boxes 421, completing the entire bottle cap testing process.
