[0009] The transfer mechanism further includes a ferrule cylinder, the cylinder rod of the ferrule cylinder is connected to an O-ring pulling block, and a pulling groove is provided on the lower surface of the O-ring pulling block; the lower surface of the O-ring pulling block reciprocates above the placement groove at the ferrule station.

[0010] Furthermore, a fixed beam and a base are provided; the vibrating bowl, the conveying mechanism, and the transfer mechanism are all arranged on the base; the fixed beam reinforces the vibrating bowl on the base.

[0011] Furthermore, a conveying mechanism support is connected to the substrate of the conveying mechanism; a transfer mechanism support is connected to the actuator of the transfer mechanism.

[0012] Furthermore, on the substrate of the conveying mechanism, a ferrule lower support plate is provided on one side of the ferrule station, and the surface of the ferrule lower support plate is flush with the upper end surface of the ferrule station.

[0015] A method for installing an O-ring using the above O-ring installation device includes the following steps:

[0016] Step 1: Pour a plurality of O-rings into the vibrating bowl, and convey the O-rings to the transfer plate of the conveying mechanism one by one through the vibrating bowl;

[0017] Step 2: If there are overlapping excess O-rings in the transfer groove of the transfer plate at the same horizontal height, the rotary cylinder drives the waste material stripping plate to rotate, and the notch on the edge of the waste material stripping plate hooks up the excess O-rings and finally falls back into the vibrating bowl;

[0018] 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;

[0019] 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.

[0020] 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;

[0022] 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;

[0023] 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;

[0025] The advantages and beneficial effects of the present invention are:

[0026] 1) The transfer mechanism can transfer the O-ring pre-sleeved on it, remove the ring at the appropriate position, and transfer the O-ring to the designated component for installation.

[0027] 2) The conveying mechanism realizes the purpose of efficiently moving O-rings one by one to the ferrule station.

[0028] 3) Through the cooperation of the vibrating bowl, the conveying mechanism and the transfer mechanism, the automatic installation process of O-rings can be realized, greatly improving the installation efficiency of O-rings. Brief Description of the Drawings

And the lowermost end of the transfer mechanism guide column 3-17 is connected to the ring stripping outer cylinder 3-19.

The ferrule cylinder 3-23 is installed on the ferrule cylinder mounting base 3-22. The cylinder rod of the ferrule cylinder 3-23 is connected to the O-ring pulling block 3-24. The lower surface of the O-ring pulling block 3-24 is provided with a pulling groove; the lower surface of the O-ring pulling block 3-24 reciprocates above the placement groove of the ferrule station 2-5 and the ferrule lower support plate 2-16.

[0056] Usage method:

[0057] 1) Pour a plurality of O-rings into the vibrating bowl 1. Through the vibrating bowl 1, the O-rings are conveyed to the transfer plate 2-7 of the conveying mechanism 2 one by one.

[0058] 2) If there are overlapping excess O-rings in the transfer groove of the transfer plate 2-7 at the same horizontal height, the rotary cylinder 2-10 drives the surplus material stripping plate 2-11 to rotate, and the notch on the edge of the surplus material stripping plate 2-11 hooks up the excess O-rings and finally drops them back into the vibrating disk 1.

[0059] The initial position state of the material transfer gripper 2-4 is that the bend at one end of the material transfer gripper 2-4 extends into the inner circle of an O-ring at the lowest part 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 material conveying plate 2-6.

[0060] Driven by the conveying slider 2-3, the material transfer gripper 2-4 is driven to move along the conveying groove in the direction of the ferrule station 2-5. When the conveying slider 2-3 moves to the limit position towards the ferrule station 2-5, exactly one end of the material transfer gripper 2-4 brings an O-ring into the conveying groove of the material conveying plate 2-6, while the other end of the material transfer gripper 2-4 moves to the placement groove of the ferrule station 2-5.

[0061] When the conveying mechanism cylinder 2-13 extends, the conveying slide rail 2-2 moves outward along the direction perpendicular to the substrate 2-1. At this time, both ends of the material transfer gripper 2-4 leave the conveying groove of the material conveying plate 2-6. The material transfer gripper 2-4 is driven by the conveying slider 2-3 to return to the starting position, and then when the conveying mechanism cylinder 2-13 retracts, the conveying slide rail 2-2 returns to the surface of the substrate 2-1. At this time, the bend at one end of the material transfer gripper 2-4 extends into the inner circle of an O-ring at the lowest part of the transfer groove of the transfer plate 2-7 (the previous lowest O-ring has moved into the conveying groove, and at this time the lowest O-ring is the next one that has fallen from above the transfer groove), and the bend at the other end of the material transfer gripper 2-4 just extends into the middle of the O-ring in the conveying groove of the material conveying plate 2-6.

[0062] After the material transfer gripper 2-4 is again driven by the conveying slider 2-3 to move along the conveying groove towards the ferrule station 2-5 for a limit distance, at this time, the first O-ring is moved by the material transfer gripper 2-4 into the placement groove of the ferrule station 2-5, and the other end of the material transfer gripper 2-4 also moves an O-ring into the conveying groove.

[0063] After removing the O-ring in the placement groove, repeating the above process can achieve the purpose of moving the O-rings one by one into the placement groove.

[0064] 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 ferrule 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; when the cylinder rod of the ferrule cylinder 3-23 retracts, the O-ring pulling block 3-24 pulls the O-ring backward and deforms it.

[0065] Two O-ring expansion needles 2-17 abut against the left and right sides of the O-ring to ensure that the two sides of the O-ring do not contract inward during the pulling process of the O-ring.

[0066] 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 above the ferrule lower support plate 2-16 (the distance between the two O-ring expansion needles 2-17 is greater than the diameter of the O-ring pre-sleeve inner cylinder 3-20 to ensure that the two O-ring expansion needles 2-17 do not hinder the movement of the O-ring pre-sleeve inner cylinder 3-20). As the O-ring pulling block 3-24 pulls the O-ring backward, finally the O-ring is sleeved on the O-ring pre-sleeve inner cylinder 3-20.

[0067] 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 drives the O-ring to move to the specified position (that is, the position where the O-ring needs to be installed on the specified component). Then, the cylinder rod of the ring-removing cylinder 3-14 pushes the ring-removing outer cylinder 3-19 to move along the outer wall surface of the O-ring pre-sleeve inner cylinder 3-20, so as to realize the ring removal of the O-ring. The O-ring is extruded away from the O-ring pre-sleeve inner cylinder 3-20 and transferred to the specified component.

[0068] 5) Repeat the above process to install the O-rings on the specified components one by one.

[0069] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.

6. A method for installing an O-ring using any one of the O-ring installation devices of claims 1 to 5, 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.
