The sliding seat 2 is slidably connected to the base 1, the push plate 8 is slidably connected to the sliding seat 2, the sleeve 6 with openings at both ends is connected to the sliding seat 2. A push ring 9 is provided at the bottom end of the push plate 8, and the push ring 9 is slidably sleeved on the outer peripheral wall of the sleeve 6. The bottom end of the plug rod 7 passes through the sleeve 6. At least two guiding ridges protrude outward from the outer peripheral wall near the bottom end of the plug rod 7. A positioning protrusion 61 protrudes downward from the bottom end of the sleeve 6. The number of the positioning protrusions 61 is the same as that of the guiding ridges. The guiding ridges can be inserted into the spaces between the positioning protrusions 61. An O-ring 10 can be placed on the loading table. The bottom wall of the O-ring 10 can abut against the top wall of the loading table. A relief hole that can cooperate with the bottom end of the plug rod 7 is provided below the O-ring 10. The plug rod 7, the sleeve 6, and the push plate 8 can move downward under the drive of the first linear movement mechanism 3. The bottom end of the plug rod 7 can insert into the inner ring of the O-ring 10 and then extend into the relief hole. The O-ring 10 can be sleeved on the guiding ridges, and the O-ring 10 can move along the guiding ridges until it is sleeved on the positioning protrusions 61.

Since the bottom wall of the O-ring 10 abuts against the top wall of the loading table, during the process of the plug rod 7 extending into the relief hole, the O-ring 10 will not be pushed by the plug rod 7, but move along the guiding ridges to the position where the guiding ridges and the positioning protrusions 61 are engaged with each other. Since the guiding ridges and the positioning protrusions 61 are engaged with each other, the O-ring 10 is sleeved on both the guiding ridges and the positioning protrusions 61 at the same time. Then the plug rod 7 retracts into the sleeve 6 under the drive of the third linear movement mechanism 5. At this time, the O-ring 10 is only sleeved on the positioning protrusions 61. In addition, when the plug rod 7 retracts into the sleeve 6, the bottom end of the sleeve 6 can be sleeved on the workpiece. When the bottom end of the sleeve 6 is sleeved on the workpiece, the push ring 9 moves downward under the drive of the second linear movement mechanism 4 to push the O-ring 10 to make the O-ring 10 disengage from the positioning protrusions 61.

A slope is arranged on the outer peripheral wall at the bottom end of the positioning protrusion 61, and a clamping groove for the O-ring 10 to be stuck into is arranged above the slope. During the process of sleeving the O-ring 10, the first end of the guiding rib with a lower height first extends into the inner ring of the O-ring 10, and then the O-ring 10 can move along the guiding rib to the position where the guiding rib and the positioning protrusion 61 are mutually clamped. During the movement of the O-ring 10, the guiding rib can play a role in positioning and guiding. In this embodiment, the transition between the first end and the second end of the guiding rib is smooth to avoid jamming during the process of sleeving the O-ring 10.

The second positioning ring abutting against the top surface of the third fixing plate 13 and the bottom surface of the positioning plate at its upper and lower ends respectively can prevent the sleeve 6 from shaking up and down, realizing the axial fixation of the sleeve 6.

[0029] Optionally, in this embodiment, the inserting rod 7 is made of anti-static material. The inserting rod 7 made of anti-static material can avoid generating static electricity during the process of sleeving the O-ring 10, thus affecting the subsequent assembly.

[0030] Assembly process: In this embodiment, the O-ring assembly device is fixed to the mobile end of an external mobile device such as a robotic arm, and the O-ring assembly device can move back and forth between the O-ring loading position and the workpiece assembly position under the drive of the external mobile device. An O-ring 10 is placed on the top wall of the loading table at the O-ring loading position. A relief hole that can cooperate with the bottom end of the insertion rod 7 is provided in the loading table below the O-ring 10. The robotic arm is a prior art and will not be elaborated in this embodiment. First, the O-ring assembly device moves to the O-ring loading position under the drive of the external mobile device. The first linear movement mechanism 3 drives the slide 2, the second linear movement mechanism 4, the third linear movement mechanism 5, the sleeve 6, the insertion rod 7, the push plate 8, and the push ring 9 to move downward together. The end of the insertion rod 7 extends into the inner ring of the O-ring 10 directly below and then into the relief hole. During this process, the bottom wall of the O-ring 10 abuts against the top wall of the loading table. Then, the O-ring 10 moves along the guiding rib to the position where the guiding rib and the positioning protrusion 61 are engaged with each other, and the O-ring 10 can be snapped into the slot of the positioning protrusion 61 along the slope. At this time, the O-ring 10 is sleeved on both the guiding rib and the positioning protrusion 61 at the same time. Then, the insertion rod 7 moves upward and retracts into the sleeve 6 under the drive of the third linear movement mechanism 5. During the process of the insertion rod 7 disengaging from the O-ring 10, the slot can prevent the O-ring 10 from being driven by the insertion rod 7. At this time, the O-ring 10 is only sleeved on the positioning protrusion 61. Then, the first linear movement mechanism 3 resets the slide 2, the second linear movement mechanism 4, the third linear movement mechanism 5, the sleeve 6, the insertion rod 7, the push plate 8, and the push ring 9 to move upward together. Then, the O-ring assembly device moves to the workpiece assembly position under the drive of the external mobile device. Then, the first linear movement mechanism 3 drives the slide 2, the second linear movement mechanism 4, the third linear movement mechanism 5, the sleeve 6, the insertion rod 7, the push plate 8, and the push ring 9 to move downward together again. Since the insertion rod 7 retracts into the sleeve 6 at this time, the bottom end of the sleeve 6 can be sleeved on the workpiece directly below. Then, the second linear movement mechanism 4 drives the push plate 8 and the push ring 9 to move downward together. Since the ring body of the push ring 9 is slidably sleeved on the outer peripheral wall of the sleeve 6 and the ring body is located above the O-ring 10, when the ring body moves downward, the ring body can push the O-ring 10 to move out of the slot along the slope and disengage from the positioning protrusion 61. Since the bottom end of the sleeve 6 is sleeved on the workpiece at this time, when the O-ring 10 disengages from the positioning protrusion 61, the O-ring 10 can just be sleeved on the workpiece. By repeating this cycle, the automatic assembly of the O-ring 10 is realized.

[0031] Using the O-ring assembly device in this embodiment has the advantage of high automation.
