[0056] Figure 1 It is a schematic structural diagram of an O-ring assembly device according to one embodiment of the present disclosure. Figure 2 It is a structural schematic diagram of an O-ring assembly device according to an embodiment of the present disclosure from another angle.

[0057] like Figure 1 and Figure 2As shown, the O-ring assembly device of the present disclosure may include: a feeding device 100, a suction device 200, a positioning device 300, a material taking device 400 and a holding device 500. The outer diameter of the O-ring is 1.5 mm and the inner diameter is 0.5 mm.

[0058] The feeding device 100 is used to provide O-rings; in a specific embodiment, the feeding device 100 can be arranged on a workbench, and it can be a flexible vibration plate. When the O-ring assembly device of the present disclosure is in use, a worker can pour a whole box of O-rings into the flexible vibration plate, and turn on the flexible vibration plate, and the O-rings are dispersed in the flexible vibration plate through the vibration of the flexible vibration plate.

[0059] At this time, the visual device can be used to determine whether the O-rings have been dispersed to a suitable degree, that is, there is no phenomenon of multiple O-rings stacking. At this time, the robot arm can move to the position of an O-ring under the guidance of the visual device and absorb the O-ring.

[0060] In the present disclosure, the robot arm may be a multi-axis multi-degree-of-freedom robot arm, and of course, it may also be a motion platform, such as a three-dimensional motion platform, etc. In a specific embodiment, the robot arm may be fixed to a workbench, and a connecting plate 600 may be provided at its end so that the connecting plate 600 can be driven and moved by the robot arm.

[0061] Figure 3 yes Figure 2 A magnified schematic diagram of part A. Figure 4 It is a schematic structural diagram of a suction device and a material taking device according to an embodiment of the present disclosure. Figure 5 It is a schematic structural diagram of a suction device according to one embodiment of the present disclosure. Figure 6 is a schematic structural diagram of a needle component 420 according to an embodiment of the present disclosure.

[0062] The suction device 200 is used to suck the O-ring provided by the feeding device 100; specifically, the suction device 200 can be fixed to the connecting plate 600, so that the robot arm can drive the suction device 200 to approach the O-ring to be sucked in a suitable posture and realize the suction of the O-ring.

[0063] More specifically, if Figure 5 As shown, the suction device 200 includes a suction head, which includes a receiving groove for receiving an O-ring, wherein a gas flow channel is opened on the bottom wall of the receiving groove so that when negative pressure is provided to the gas flow channel, the O-ring can be sucked and retained in the receiving groove.

[0064] Figure 7 It is a schematic structural diagram of a positioning device according to an embodiment of the present disclosure. Figure 8 yes Figure 7 An enlarged schematic diagram of part B.

[0065] like Figure 7 As shown, the positioning device 300 is used to receive the O-ring sucked by the suction device 200 and position the O-ring; in the present disclosure, the positioning device 300 can be fixed to the workbench. After the suction device 200 sucks the O-ring, it can be judged whether the O-ring is stably held according to the gas pressure in the gas flow channel, and when the O-ring is stably held, the mechanical arm drives the suction device 200 to move to the top of the positioning device 300, at which time the negative pressure applied to the gas flow channel is stopped, and the O-ring can fall to the positioning device 300 by gravity and be positioned by the positioning device 300.

[0066] In a specific embodiment, the positioning device 300 can be a jaw cylinder, which includes two jaws that can approach or move away from each other, wherein each jaw is provided with a receiving groove for receiving at least part of the O-ring. Specifically, each receiving groove forms a half-groove structure, and the receiving grooves of the two jaws can be combined into a circular groove, and the O-ring can be positioned in the circular groove. In this case, the circular groove can also be called a countersunk hole.

[0067] In addition, a groove structure is provided along the height direction of the jaw cylinder from the bottom wall of the accommodating groove, and the groove structure is used to accommodate the needle component 420. Specifically, the groove structure can also be formed as a half groove, and the groove structures of the two jaws can be formed as through holes. In a preferred embodiment, the inner diameter of the circular groove is larger than the inner diameter of the through hole, so that the O-ring can be supported and retained by the bottom wall of the circular groove.

[0068] The material taking device 400 is used to take out the O-ring positioned by the positioning device 300 and keep it in the material taking device 400; specifically, Figure 3 and Figure 4 As shown, the material taking device 400 of the present disclosure is also fixed on the connecting plate 600, and preferably, the material taking device 400 and the suction device 200 are located on both sides of the connecting plate 600 so that the working process of sucking the O-ring and the working process of removing the O-ring do not interfere with each other.

[0069] More specifically, if Figure 3 , Figure 4 and Figure 6 As shown, the material taking device 400 may include: a first driving device 410, a needle component 420, a sleeve component 430 and other structures.

[0070] The first driving device 410 is disposed on the connecting plate 600 ; wherein the first driving device 410 is a linear driving device, such as a pneumatic cylinder, a hydraulic cylinder or an electric cylinder.

[0071] The needle component 420 is installed on the first driving device 410, and the first driving device 410 is used to drive the needle component 420 to move along its axial direction, wherein a plurality of groove portions 423 are provided on the outer peripheral surface of the needle component 420 along its axial direction; in a preferred embodiment, the number of the groove portions 423 is four, and of course, the number of the groove portions 423 can also be other values; these four groove portions 423 can be evenly distributed along the outer peripheral surface of the needle component 420.

[0072] More preferably, the needle component 420 includes a rod component 421 and a head component 422 connected to the rod component 421. Specifically, the rod component 421 can be formed into a cylindrical shape, and the upper end of the rod component 421 is connected to the first driving device 410; the head component 422 is formed into an inverted cone structure or an inverted truncated cone structure, and the needle component 420 is formed with a substantially pointed structure.

[0073] In the present disclosure, at least part of the groove portion 423 is located at the rod component 421 and at least part of the groove portion 423 is located at the head component 422 , thereby enabling the O-ring sleeved on the needle component 420 to be transferred to the sleeve component through the sleeve component 430 described below.

[0074] The sleeve part 430 is arranged on the connecting plate 600 and is sleeved on the outside of the needle part 420, and the sleeve part 430 includes a plurality of claw parts 431, and the claw parts 431 are at least partially located in the groove part 423 of the needle part 420; more specifically, the plurality of claw parts 431 are evenly distributed along the circumference of the needle part 420, wherein a claw part 431 is arranged in each groove part 423.

[0075] In a preferred embodiment, taking the shape of the cross section as an example, the claw member 431 has substantially the same shape as the groove portion 423 , and when the needle member 420 is driven and moves, the claw member 431 can slide in the groove portion 423 .

[0076] In actual use, when the robot arm drives the material taking device 400 to move to the top of the O-ring to be taken, the first driving device 410 is activated and the needle component 420 is extended from the structure enclosed by the claw component 431, so that the head of the needle component 420 can be inserted into the center hole of the O-ring. Then, as the needle component 420 continues to move downward, the positioning device 300 applies an upward supporting force to the O-ring and prevents the O-ring from moving downward, and then the O-ring will gradually move to the rod component 421 of the needle component 420 and be held by the rod component 421.

[0077] Moreover, as the needle component 420 moves downward, the needle component 420 can be located in the groove structure of the clamp; in addition, as the insertion depth of the needle component 420 changes, the two clamps can move away from each other so that the clamps will not affect the downward movement of the needle component 420.

[0078] After the O-ring is held on the needle component 420 , the robot arm drives the material taking device 400 to move above the holding device 500 , and the O-ring can be installed.

[0079] Specifically, the holding device 500 is used to hold the workpiece to be assembled, and the material removal device 400 is used to install the O-ring held by it on the workpiece to be assembled. For example, the holding device 500 includes a clamping cylinder, and the workpiece to be assembled is a piston, and the piston is clamped and held by the clamping cylinder.

[0080] At this time, the material picking device 400 also includes: a second driving device 440 and a pushing plate 450 and other components; the second driving device 440 is arranged on the connecting plate 600; wherein the second driving device 440 can be a linear motion structure such as a cylinder, a hydraulic cylinder or an electric cylinder; the pushing plate 450 is arranged on the second driving device 440, and is driven by the second driving device 440 to approach or move away from the sleeve component 430, wherein a through hole is opened on the pushing plate 450, and the claw component 431 of the sleeve component 430 can be slidably arranged in the through hole.

[0081] Specifically, after the O-ring is sleeved on the needle component 420 , the first driving device 410 can drive the needle component 420 to move upward. At this time, the O-ring will be transferred to the claw component 431 of the sleeve component 430 and sleeved on the outside of the claw component 431 .

[0082] The robotic arm drives the material picking device 400 to move above the holding device 500. At this time, the lower end of the claw component 431 contacts and cooperates with the upper end of the piston, and the claw component 431 has an outer diameter that is roughly the same as the piston structure. Therefore, when the axis of the claw component 431 is aligned with the axis of the piston, the outer peripheral surface of the claw component 431 is also aligned with the outer peripheral surface of the piston; then the second driving device 440 is actuated, and the push plate 450 drives the O-ring mounted on the claw component 431 downward and transfers it to the piston, thereby realizing the installation of the O-ring.

[0083] In the present disclosure, the diameter of the through hole of the push plate 450 is slightly larger than the outer diameter of the claw part 431, that is, the gap between the inner wall of the through hole of the push plate 450 and the outer surface of the claw part 431 should not be too large. For example, the gap needs to be smaller than the cross-sectional diameter of the O-ring. Thus, the push plate 450 can remove the O-ring from the claw part 431 and press it onto the piston.

[0084] Based on the above structure, the O-ring assembly device disclosed in the present invention can realize automated O-ring assembly, has high production efficiency requirements, and can stably fit the O-ring onto the piston, solving the current problems of small O-ring size, inconvenient manual work, and low yield rate.
