A product conveying mechanism 5 is disposed at the middle of the upper part of the frame 1 to rotate and transfer products. A product feeding mechanism 4 for unloading and conveying products is disposed around the product conveying mechanism 5. An O-ring assembly mechanism 6 assembles the conveyed products with O-rings. A vision mechanism 7 performs visual inspection on the products with O-rings. A finished product discharge mechanism 8 picks up and conveys the visually inspected and qualified products from the product conveying mechanism 5. Furthermore, when products to be assembled with O-rings are piled up... When placed inside the product feeding mechanism 4, the product feeding mechanism 4 drops the product one by one onto the product conveying mechanism 5. The product conveying mechanism 5 rotates and transports the product one by one to the O-ring assembly mechanism 6. At the same time, the O-ring assembly mechanism 6 conveys the O-rings stored inside and assembles them with the products below it. The products with O-rings are then rotated and transported by the product conveying mechanism 5 to the vision mechanism 7 for visual inspection, thereby checking whether the O-rings are properly assembled with the product. After visual inspection, the products are then rotated and transported by the product conveying mechanism 5 to the finished product discharge mechanism 8. The finished product discharge mechanism 8 then picks up the product from the product conveying mechanism 5 and transports it out from the frame 1.

[0033] The product feeding mechanism 4 includes a first vibratory plate 16 mounted on a frame 1 and a first support 11 located on one side of the first vibratory plate 16. A first support 9 connected to the first vibratory plate 16 is located on the side away from the first support 11. Products that are assembled with O-rings are stacked inside the first vibratory plate 16. The products stacked inside the first vibratory plate 16 can be vibrated and transferred one by one to the first support 9. A second slider 14 is movably mounted on one side of the first support 11.

[0036] The first drive cylinder 13, the second drive cylinder 15, and the first finger cylinder 10 are electrically connected to the first sensor 17. When the first vibrating plate 16 vibrates and transports the product inside to the first support 9, the first sensor 17 on the first support 9 senses the position of the product and transmits the sensed signal to the first drive cylinder 13, the second drive cylinder 15, and the first finger cylinder 10. This causes the second drive cylinder 15 to drive the second slider 14, along with the first slider 12 and the first finger cylinder 10, to move to a predetermined position above the product. Meanwhile, the first drive cylinder 13 drives the first slider 12, along with the first finger cylinder 10, to move... The cylinder 10 moves downward and causes the first finger cylinder 10 to grip the product on the first support 9. After the first finger cylinder 10 grips the product, the first drive cylinder 13 and the second drive cylinder 15 drive the first slider 12 and the second slider 14 to reset, thereby moving the product gripped by the first finger cylinder 10 to above the product conveying mechanism 5. Then, through the driving cooperation of the first drive cylinder 13 and the second drive cylinder 15, the product gripped by the first finger cylinder 10 is placed on the product conveying mechanism 5 so that the product can be rotated and conveyed to the O-ring assembly mechanism 6 below for O-ring assembly.

A motor 18 is disposed between the divider 19 and the frame 1. The motor 18 is located inside the frame 1 and is driven by the divider 19. The motor 18 drives the divider 19 and the disk 20 to rotate. When the disk 20 rotates, it can also rotate the product carriers 21 and the products carried on the product carriers 21 and transport the products to the corresponding processing mechanism.

A second support 32 communicating with the second vibratory plate 32 is located on the side away from the second support 221. O-rings to be assembled with the product are stacked inside the second vibratory plate 32. The second vibratory plate 31 can vibrate and transfer the stacked O-rings one by one to the second support 32. A fourth slider 27 is movably mounted on one side of the second support 22, and the fourth slider 27 is positioned on its... A third slider 25 moves up and down on the side, and a second finger cylinder 29 and a collar rod 24 that move up and down synchronously are provided at the bottom of the third slider 25. The collar rod 24 is located on one side of the second finger cylinder 29, and the second finger cylinder 29 and the collar rod 24 are parallel to each other with the second support 32.

A third driving cylinder 23 is provided between the third slider 25 and the ring rod 24, and the third driving cylinder 23 is driven to the ring rod 24.

[0041] The third drive cylinder 23, the fourth drive cylinder 26, the fifth drive cylinder 28, and the second finger cylinder 29 are electrically connected to the second sensor 30. When the second vibrating plate 31 vibrates and transports the O-ring inside it to the second support 32, the second sensor 30 on the second support 32 senses the position of the O-ring and transmits the sensed signal to the third drive cylinder 23, the fourth drive cylinder 26, the fifth drive cylinder 28, and the second finger cylinder 29. This causes the third drive cylinder 23 to drive the ring rod 24 to move up and down on the side of the third slider 25, thereby driving the second finger cylinder 29 to move onto the second support 32 and clamp the O-ring on the second support 32, transporting it to the second support. Above the gripper 34, the pneumatic gripper 34 moves upward to the center of the O-ring and opens it. At this time, the fourth slider 27 continues to move and moves the third slider 25 together with the ring-fitting rod 24 above the pneumatic gripper 34. Simultaneously, the third drive cylinder 23 drives the ring-fitting rod 24 to move to the center of the pneumatic gripper 34, and the pneumatic clamp 34 closes in the middle so that the O-ring is fitted onto the ring-fitting rod 24. Then, through the driving cooperation of the third drive cylinder 23, the fourth drive cylinder 26 and the fifth drive cylinder 28, the ring-fitting rod 24 is fitted with the O-ring and inserted into the product placed on the product conveying mechanism 5 and assembled with the product. This allows the product equipped with the O-ring to be rotated and conveyed to the vision mechanism 7 for visual inspection later by the product conveying mechanism 5.

The sixth slider 41 is driven by the eighth driving cylinder 42 to slide horizontally on one side of the third support 43, and the sixth slider 41 slides, which in turn moves the fifth slider 39 and the third finger cylinder 38 located below the fifth slider 39.

[0046] A seventh driving cylinder 40 is provided between the fifth slider 39 and the sixth slider 41. The seventh driving cylinder 40 is located at the top of the sixth slider 41 and is connected to the fifth slider 39. The seventh driving cylinder 40 drives the fifth slider 39 and moves the third finger cylinder 38 downward. Through the sliding cooperation between the fifth slider 39 and the sixth slider 41, the product on the product conveying mechanism 5 can be clamped and transported into the superior and defective product funnel 44.

[0047] The superior and inferior product funnel 44 is equipped with a ninth cylinder 45 inside it, and the ninth cylinder 45 drives a valve plate (not shown in the figure) that moves inside the superior and inferior product funnel 44. Thus, when the valve plate is driven by the ninth cylinder 45 to move inside the superior and inferior product funnel 44, the product inside can slide into the corresponding flow channel.
