[0009] Preferably, the shell is provided with a plurality of limit grooves, a limit rod is slidably connected in the limit groove, and the lower end of the limit rod is fixedly connected to the positioning sleeve.

[0010] Preferably, the O-ring feeding mechanism includes a rotating table, and a plurality of barrels are arranged at intervals along the circumference of the rotating table. The upper end of the barrel is the feeding end, and a separation mechanism is provided on the outside of the feeding end. The separation mechanism slides back and forth along the axial direction of the barrel to peel off the O-ring located at the top of the barrel and transport it to the feeding end.

[0011] Preferably, the separation mechanism comprises a dividing plate, the dividing plate is provided with a plurality of dividing openings, sealing grooves are arranged at intervals along the dividing openings, a stripping block is slidably connected in the sealing groove, and the dividing plate is provided with a driving cylinder for driving the stripping block to slide back and forth in the sealing groove.

[0012] Preferably, first positioning protrusions are arranged at intervals on the upper end of the barrel, positioning grooves are formed between adjacent first positioning protrusions, and a second positioning protrusion cooperating with the positioning groove is provided at the lower end of the positioning sleeve.

[0015] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0016] 1. In the present application, the L-shaped support mechanism can provide stable support for the grabbing mechanism and the O-ring feeding mechanism to ensure the precise coordination between the grabbing mechanism and the O-ring feeding mechanism. The staff will install the O-rings that have passed the batch inspection onto the O-ring feeding mechanism, start the grabbing mechanism to grab the O-ring located at the first position of the feeding end of the O-ring feeding mechanism, and then the rotating mechanism controls the grabbing mechanism to rotate to the second position, and press-fit the grabbed O-ring onto the engine body installation station, thereby realizing the automatic installation of the O-ring, greatly increasing the installation efficiency of the O-ring. At the same time, replacing manual assembly with mechanical automatic assembly can also reduce the error rate of manual assembly of O-rings, increase the assembly accuracy of O-rings and the consistency of batch products, and reduce labor costs.

[0017] 2. As a preferred embodiment of the utility model, when the grabbing mechanism performs a grabbing action, the rotating mechanism drives the shell to rotate and rotates the positioning sleeve to above the feeding end of the O-ring feeding mechanism. At this time, the second telescopic cylinder performs an extending action to push out the positioning sleeve, so that the positioning sleeve cooperates with the feeding end of the O-ring feeding mechanism and receives the O-ring located in the first position. After the O-ring is sleeved on the positioning sleeve, the rotating mechanism performs a rotating action, rotating 180° to rotate the O-ring from the first position to the second position. At this time, the second telescopic cylinder performs a recovery action to drive the positioning sleeve to slide into the sliding groove. At the same time, the annular pressure plate peels off the O-ring sleeved on the positioning sleeve and presses it onto the engine body installation station.

[0018] When the O-ring is sleeved on the positioning sleeve, the lower end of the pressure claw rotates and turns outward toward the outside of the positioning sleeve along the fixed rotating fulcrum to prop up and fix the O-ring to prevent it from falling off the positioning sleeve. An elastic member is provided between the pressure claw and the positioning sleeve. During the extension of the second telescopic cylinder, the positioning sleeve slides outward from the sliding groove, the pressure of the inner wall of the sliding groove on the pressure claw is gradually withdrawn, and the pressure claw pops out. Conversely, during the recovery of the second telescopic cylinder, the positioning sleeve slides into the sliding groove, the pressure of the inner wall of the sliding groove on the pressure claw gradually increases, and the pressure claw is pressed into the rotating gap by the inner wall of the sliding groove.

[0019] 3. As a preferred embodiment of the utility model, the rotating shaft can be driven to rotate 0-180° by the rotating cylinder. It is worth mentioning that the staff inputs a specified rotation angle into the controller to adjust the specific rotation angle of the rotating cylinder, so that the rotating shaft drives the grabbing mechanism to swing back and forth between the first position and the second position. In the process of the grabbing mechanism rotating with the rotating shaft, the first telescopic cylinder telescopes and adjusts the position of the grabbing mechanism, so that the grabbing mechanism is accurately matched with the first position and the second position.

[0020] 4. As a preferred embodiment of the present invention, the sliding process of the positioning sleeve can be limited by setting the limiting groove and the limiting rod, thereby increasing the sliding accuracy of the positioning sleeve.

[0021] 5. As a preferred embodiment of the utility model, the diameters of several barrels can be the same or different. O-rings of different diameters can be mounted on barrels of different diameters to adapt to different types of engine bodies. When the O-ring on one of the barrels is installed, the barrel loaded with the O-ring can be rotated to the bottom of the separation mechanism by rotating the rotating table. The separation mechanism is controlled to move downward to cooperate with the barrel by the linear guide rail. After the separation mechanism peels off the O-ring at the top of the barrel, the separation mechanism is controlled to move upward by the linear guide rail to transport the peeled O-ring to the first position.

[0022] 6. As a preferred embodiment of the utility model, during the downward movement of the separation mechanism, the stripping blocks are all located in the sealing groove, and a channel with a width greater than the diameter of the O-ring is formed between the dividing plate and the barrel. When the dividing plate slides downward until the upper end of the stripping block is just below the uppermost O-ring, the dividing plate stops moving. At this time, the driving cylinder inflates the sealing groove to push the stripping block along the sealing groove. The stripping block lifts the uppermost O-ring, and then drives the dividing plate to move upward, so that the stripping block strips the O-ring from the barrel and transports it to the first position.

[0023] 7. As a preferred embodiment of the present invention, the first positioning protrusion and the second positioning protrusion facilitate precise matching between the positioning sleeve and the feeding end of the barrel, thereby ensuring the accuracy of the O-ring transfer process.

[0024] 8. As a preferred embodiment of the utility model, the protective plate divides the turntable into a feeding area away from the grabbing mechanism and the rotating mechanism and a loading area close to the grabbing mechanism and the rotating mechanism. O-rings of corresponding types can be manually added to the barrel in the feeding area, so that workers can maintain a certain safe distance from the grabbing mechanism, the rotating mechanism and other equipment, thereby increasing the safety of workers when feeding.

[0037] Reference Figure 1-4, an O-ring automatic grabbing device comprises an L-shaped support mechanism, the L-shaped support mechanism has a horizontal support part and a vertical support part, an O-ring feeding mechanism is arranged on the horizontal support part, the O-ring has a first position sleeved on the feeding end of the O-ring feeding mechanism and a second position installed at the engine body installation station, the vertical support part is provided with a grabbing mechanism for grabbing the O-ring at the feeding end of the O-ring feeding mechanism; and also includes a rotating mechanism arranged on the vertical support part, the rotating mechanism is used to control the grabbing mechanism to grab the O-ring at the first position and rotate to install the grabbed O-ring at the second position.

[0038] It can be understood by those skilled in the art that the engine block and the cylinder head need to be sealed by an O-ring, and the engine block needs to be fixed to the side of the L-shaped support mechanism by a support fixture so that the O-ring installation position on the engine cylinder matches the second position. The L-shaped support mechanism can provide stable support for the grabbing mechanism and the O-ring feeding mechanism, ensuring the precise coordination of the grabbing mechanism and the O-ring feeding mechanism. The staff will add the qualified O-rings in batches to the O-ring feeding mechanism, start the grabbing mechanism to grab the O-rings at the first position of the feeding end of the O-ring feeding mechanism, and then the rotating mechanism controls the grabbing mechanism to rotate to the second position, and presses the grabbed O-rings onto the engine body installation position, thereby realizing the automatic installation of the O-rings, greatly increasing the installation efficiency of the O-rings. At the same time, replacing manual assembly with mechanical automatic assembly can also reduce the error rate of manual assembly of O-rings, increase the assembly accuracy of O-rings and the consistency of batch products, and reduce labor costs.

[0039] As a specific implementation of the material grabbing mechanism in this application, refer to Figure 1-Figure 3 The material grabbing mechanism includes a shell 5, a ring-shaped pressure plate 502 is fixedly connected to the bottom of the shell 5, a sliding groove matching the inner diameter of the ring-shaped pressure plate 502 is provided at the bottom of the shell 5, a positioning sleeve 503 matching the inner diameter of the O-ring is slidably connected in the sliding groove, and a second telescopic cylinder 504 for driving the positioning sleeve 503 to slide is provided in the shell 5.

[0040] When the grabbing mechanism performs the grabbing action, the rotating mechanism drives the shell 5 to rotate and rotate the positioning sleeve 503 to above the feeding end of the O-ring feeding mechanism. At this time, the second telescopic cylinder 504 performs the extending action to push out the positioning sleeve 503, so that the positioning sleeve 503 cooperates with the feeding end of the O-ring feeding mechanism and receives the O-ring located at the first position. After the O-ring is sleeved on the positioning sleeve 503, the rotating mechanism performs the rotating action, rotating 180° to rotate the O-ring from the first position to the second position. At this time, the second telescopic cylinder 504 performs the recovering action to drive the positioning sleeve 503 to slide into the sliding groove. At the same time, the annular pressure plate 502 peels off the O-ring sleeved on the positioning sleeve 503 and presses it onto the engine body installation station.

[0041] The cam 506 is provided with a plurality of rotation slots at the bottom end of the side wall of the positioning sleeve 503, and the plurality of rotation slots are arranged at intervals along the circumference of the outer wall of the positioning sleeve 503. A pressure claw 506 is rotatably connected in the rotation slot. When the O-ring is sleeved on the positioning sleeve 503, the lower end of the pressure claw 506 rotates and turns outward toward the outside of the positioning sleeve 503 along the fixed rotation fulcrum to prop up and fix the O-ring to prevent it from falling off the positioning sleeve 503. An elastic member is provided between the pressure claw 506 and the positioning sleeve 503. During the extension of the second telescopic cylinder 504, the positioning sleeve 503 slides outward from the sliding groove, and the pressure of the inner wall of the sliding groove on the pressure claw 506 is gradually withdrawn, and the pressure claw 506 pops out. Conversely, during the recovery of the second telescopic cylinder 504, the positioning sleeve 503 slides into the sliding groove, and the pressure of the inner wall of the sliding groove on the pressure claw 506 is gradually increased, and the pressure claw 506 is pressed into the rotation slot by the inner wall of the sliding groove.

[0042] As a specific implementation of the rotating mechanism in this application, refer to Figure 1 and Figure 2 The rotating mechanism includes a rotating shaft 4 and a rotating cylinder 401 for driving the rotating shaft 4 to rotate. The rotating shaft 4 is fixedly connected to the vertical support portion through a bearing seat. The side wall of the rotating shaft 4 is fixedly connected to a first telescopic cylinder 501. The telescopic end of the first telescopic cylinder 501 is fixedly connected to the material grabbing mechanism.

[0043] The rotating cylinder 401 can drive the rotating shaft 4 to rotate 0-180°. It is worth mentioning that the staff inputs a specified rotation angle into the controller to adjust the specific rotation angle of the rotating cylinder 401, so that the rotating shaft 4 drives the grabbing mechanism to swing back and forth between the first position and the second position. In the process of the grabbing mechanism rotating with the rotating shaft 4, the first telescopic cylinder 501 telescopes and adjusts the position of the grabbing mechanism so that the grabbing mechanism is accurately matched with the first position and the second position.

The setting of the limit groove and the limit rod 505 can limit the sliding process of the positioning sleeve 503, thereby increasing the sliding accuracy of the positioning sleeve 503.

[0045] As a specific implementation of the O-ring feeding mechanism, refer to Figure 1 and Figure 4The O-ring feeding mechanism includes a rotating table 2, and a plurality of barrels 3 are arranged at intervals along the circumference of the rotating table 2. The upper end of the barrel 3 is the feeding end, and a separation mechanism is provided on the outer sleeve of the feeding end. The separation mechanism reciprocates along the axial direction of the barrel 3 to peel off the O-ring located at the top of the barrel 3 and transport it to the feeding end.

[0046] The diameters of several barrels 3 can be the same or different. O-rings of different diameters can be mounted on barrels 3 of different diameters to adapt to different types of engine bodies.

The separation mechanism is controlled to move downward to cooperate with the barrel 3 by the linear guide rail. After the separation mechanism peels off the O-ring at the top of the barrel 3, the separation mechanism is controlled to move upward by the linear guide rail to transfer the peeled O-ring to the first position.

[0047] Among them, the separation mechanism includes a material separation plate 6, which is provided with a plurality of material separation openings, and sealing grooves 601 are arranged at intervals along the material separation openings. A stripping block 602 is slidably connected in the sealing groove 601, and a driving cylinder 603 is provided on the material separation plate 6 for driving the stripping block 602 to slide back and forth in the sealing groove 601.

[0048] During the downward movement of the separation mechanism, the stripping block 602 is completely located in the sealing groove 601, and a channel with a width greater than the diameter of the O-ring is formed between the dividing plate 6 and the barrel 3. When the dividing plate 6 slides downward until the upper end of the stripping block 602 is just below the uppermost O-ring, the dividing plate 6 stops moving. At this time, the driving cylinder 603 inflates the sealing groove 601 to push the stripping block 602 along the sealing groove 601.
