A transfer mechanism guide seat 3-18 is provided at the position of the through holes, and a transfer mechanism guide column 3-17 passes through the through holes of the transfer mechanism guide seat 3-18 and the O-ring pre-sleeved inner cylinder mounting seat 3-16, and the lower end of the transfer mechanism guide column 3-17 is connected to the ring-detaching outer cylinder 3-19, and the ring-detaching outer cylinder 3-19 is located below the O-ring pre-sleeved inner cylinder mounting seat 3-16.

[0040] An O-ring pre-sleeve inner cylinder 3-20 is provided on the lower surface of the O-ring pre-sleeve inner cylinder mounting seat 3-16, and is located inside the unsleeving outer cylinder 3-19. The inner wall of the unsleeving outer cylinder 3-19 can move along the outer wall surface of the O-ring pre-sleeve inner cylinder 3-20, and the front end of the O-ring pre-sleeve inner cylinder 3-20 is exposed from the front end of the unsleeving outer cylinder 3-19.

[0042] Directions: 1) Pour a plurality of O-rings into the vibrating plate 1, and transport the O-rings one by one to the transfer plates 2-7 of the conveying mechanism 2 through the vibrating plate 1.

[0043] 2) If there are redundant O-rings overlapping in the transfer groove of the transfer plate 2-7 at the same horizontal height, the rotary cylinder 2-10 drives the residual material stripping plate 2-11 to rotate, and the notch at the edge of the residual material stripping plate 2-11 hooks up the redundant O-rings and finally drops them back to the vibration plate 1.

[0044] The initial position state of the material transfer gripper 2-4 is: the bend at one end of the material transfer gripper 2-4 extends into the circle of an O-ring located at the bottom of the transfer groove of the transfer plate 2-7, and the bend at the other end of the material transfer gripper 2-4 extends into the conveying groove of the feed plate 2-6.

[0045] By driving the conveying slider 2-3, the material moving grab 2-4 is driven to move along the conveying groove toward the ring station 2-5. When the conveying slider 2-3 moves to the limit position toward the ring station 2-5, one end of the material moving grab 2-4 enters the conveying groove of the conveying plate 2-6 with an O-ring, and the other end of the material moving grab 2-4 moves to the placement groove of the ring station 2-5.

[0046] The conveying mechanism cylinder 2-13 extends outward, so that the conveying slide rail 2-2 moves outward in a direction perpendicular to the substrate 2-1. At this time, both ends of the material moving catch 2-4 leave the conveying groove of the conveying plate 2-6, and the material moving catch 2-4 is driven back to the starting position by the conveying slider 2-3, and then the conveying mechanism cylinder 2-13 retracts, so that the conveying slide rail 2-2 returns to the surface of the substrate 2-1. At this time, the bend of one end of the material moving catch 2-4 extends into the circle of an O-ring located at the bottom of the transfer groove of the transfer plate 2-7 (the previous bottom O-ring has moved into the conveying groove, and the bottom O-ring is the next one to fall from the transfer groove), and the bend of the other end of the material moving catch 2-4 just extends into the middle of the O-ring located in the conveying groove of the conveying plate 2-6.

[0047] After the conveying slider 2-3 drives the material transfer gripper 2-4 to move a maximum distance along the conveying groove toward the ring station 2-5, the first O-ring is moved to the placement groove of the ring station 2-5 by the material transfer gripper 2-4, and the other end of the material transfer gripper 2-4 also moves an O-ring to the conveying groove.

[0048] After the O-ring in the placement groove is removed, the above process is repeated to achieve the purpose of moving the O-rings to the placement groove one by one.

[0049] 3) When there is an O-ring in the placement groove, the lower part of the O-ring is in the placement groove of the ring station 2-5, and the upper part of the O-ring is stuck in the pulling groove of the O-ring pulling block 3-24; the cylinder rod of the ring cylinder 3-23 retracts, and the O-ring pulling block 3-24 pulls the O-ring backward to deform it.

[0050] Two O-ring expansion needles 2-17 are pressed against the left and right sides of the O-ring to ensure that the two sides of the O-ring will not shrink inwards during the pulling process of the O-ring.

[0051] Under the action of the first cylinder 3-2 and the second cylinder 3-12, the O-ring pre-sleeve inner cylinder 3-20 moves to above the ring lower support plate 2-16 (the distance between the two O-ring expansion needles 2-17 is larger than the diameter of the O-ring pre-sleeve inner cylinder 3-20, ensuring that the two O-ring expansion needles 2-17 will not hinder the movement of the O-ring pre-sleeve inner cylinder 3-20), and as the O-ring pulling block 3-24 pulls the O-ring backward, the O-ring is finally inserted into the O-ring pre-sleeve inner cylinder 3-20.

[0052] 4) Under the action of the first cylinder 3-2 and the second cylinder 3-12, the O-ring pre-sleeve inner cylinder 3-20 is moved with the O-ring to the specified position (that is, the O-ring needs to be installed to the position of the specified component), and then the cylinder rod of the unsleeving cylinder 3-14 pushes the unsleeving outer cylinder 3-19 to move along the outer wall surface of the O-ring pre-sleeve inner cylinder 3-20, thereby realizing the unsleeving of the O-ring, and the O-ring is squeezed out of the O-ring pre-sleeve inner cylinder 3-20 and transferred to the specified component.

[0053] 5) Repeat the above process to install the O-rings on the specified parts one by one.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.

The O-ring installation device according to claim 1, characterized in that: A conveying mechanism bracket is provided on the base plate, and a rotating cylinder is provided on the conveying mechanism bracket. The cylinder rod of the rotating cylinder is connected to the residual material stripping plate; the residual material stripping plate is deflected clockwise or counterclockwise along a direction perpendicular to the transfer plate, and a notch for hooking the O-ring is provided on the edge of the residual material stripping plate facing the transfer plate.

8. A method for installing an O-ring using any one of the O-ring installation devices of claims 1 to 7, characterized in that: The following steps are involved: Step 1: Pour multiple O-rings into the vibration plate, and transport the O-rings one by one to the transfer plate of the conveying mechanism through the vibration plate; Step 2: If there are redundant O-rings overlapping in the transfer groove of the transfer plate at the same horizontal height, the rotary cylinder drives the residual material stripping plate to rotate, and the notch at the edge of the residual material stripping plate hooks up the redundant O-rings and finally drops them back to the vibration plate; Initially, the bend at one end of the material transfer gripper extends into an O-ring located at the bottom of the transfer groove of the transfer plate, and the bend at the other end of the material transfer gripper extends into the conveying groove of the feed plate; The conveying slider drives the material moving gripper to move along the conveying groove toward the ring station. When the conveying slider moves to the limit position toward the ring station, one end of the material moving gripper enters the conveying groove of the conveying plate with an O-ring, and the other end of the material moving gripper moves to the placement groove of the ring station. The conveying mechanism cylinder is extended, so that the conveying slide rail moves outward in a direction perpendicular to the substrate; both ends of the material moving gripper leave the conveying groove of the material conveying plate, and the material moving gripper is driven back to the starting position by the conveying slider, and then the conveying mechanism cylinder is retracted, so that the conveying slide rail returns to the surface of the substrate; the bend of one end of the material moving gripper extends into the circle of an O-ring located at the bottom of the transfer groove of the transfer plate, and the bend of the other end of the material moving gripper just extends into the middle of the O-ring located in the conveying groove of the material conveying plate; The conveying slider drives the material transfer gripper to move a limit distance along the conveying trough to the ring station, and the first O-ring is moved to the placement groove of the ring station by the material transfer gripper, while the other end of the material transfer gripper also moves an O-ring to the conveying trough; Step 3: When there is an O-ring in the placement groove, the lower part of the O-ring is in the placement groove of the ring station, and the upper part of the O-ring is stuck in the pulling groove of the O-ring pulling block; the cylinder rod of the ring cylinder retracts, and the O-ring pulling block pulls the O-ring backward to deform it; two O-ring expansion needles are pressed against the left and right sides of the O-ring to ensure that the two sides of the O-ring will not shrink inward during the pulling process of the O-ring; through the action of the first cylinder and the second cylinder, the O-ring pre-sleeve inner cylinder moves to the top of the ring lower support plate, and as the O-ring pulling block pulls the O-ring backward, the O-ring is finally inserted into the O-ring pre-sleeve inner cylinder; Step 4: The O-ring pre-sleeved inner cylinder is moved to the designated component with the O-ring through the action of the first cylinder and the second cylinder, and then the cylinder rod of the unsleeving cylinder pushes the unsleeving outer cylinder to move along the outer wall surface of the O-ring pre-sleeved inner cylinder, thereby realizing the unsleeving of the O-ring, and the O-ring is squeezed out of the O-ring pre-sleeved inner cylinder and transferred to the designated component; Step 5: Repeat the above process to install the O-rings on the designated parts one by one.
