[0041] This embodiment provides a sealing ring assembly device. Refer to Figures 1 to 5As shown, the seal ring assembly device is used to install the seal ring 6 into the installation hole of the part to be installed. The seal ring assembly device includes a feeding system 1, a positioning system 2, a transportation system 3, a lubrication system 4 and a detection system 5. Among them, the feeding system 1 is used to feed the seal ring 6, the positioning system 2 is used to position the part to be installed, the transportation system 3 includes a robotic arm 31 and a clamping member 32 provided on the robotic arm 31. The robotic arm 31 can drive the clamping member 32 to move. The clamping member 32 is used to clamp the seal ring 6 and install the seal ring 6 into the installation hole of the part to be installed on the positioning system 2. The lubrication system 4 is used to spray lubricating oil into the installation hole of the part to be installed on the positioning system 2.

[0042] In this embodiment, the seal ring assembly device can automatically assemble the seal ring 6 onto the part to be installed. The setting of the feeding system 1 realizes the automatic feeding of the seal ring 6. The setting of the positioning system 2 realizes the positioning and fixation of the part to be installed. The robotic arm 31 drives the clamping member 32 to move, so that the clamping member 32 can clamp the seal ring 6 provided by the feeding system 1, and transfer and install the seal ring 6 into the installation hole of the part to be installed placed on the positioning system 2, thus realizing the automatic assembly of the seal ring 6. After the assembly is completed, the lubrication system 4 can spray lubricating oil into the installation hole of the part to be installed on the positioning system 2. This device can realize the automatic feeding, assembly and lubrication of the seal ring 6, with high automation degree, high assembly precision, stable assembly quality, and reduced consumption of labor costs.

[0043] In this embodiment, the part to be installed can be a cylinder head, and the installation hole opened on the part to be installed corresponds to the bottom hole of the fuel injector 41 of the cylinder head. Specifically, an annular groove is provided on the inner peripheral wall of the installation hole. When the seal ring 6 is assembled in place, part of the seal ring 6 is located in the annular groove.

[0044] The specific structure of the robotic arm 31 is prior art and will not be elaborated here.

[0045] In this embodiment, the seal ring 6 is set as an O-ring 6.

[0046] In this embodiment, the lubrication system 4 includes an oil tank (not shown), a fuel injection pump (not shown) and a fuel injector 41. The oil tank is connected to the inlet of the fuel injection pump, the outlet of the fuel injection pump is connected to the fuel injector 41, and the fuel injector 41 is located above the positioning system 2 and is used to spray lubricating oil into the installation hole of the part to be installed on the positioning system 2. Specifically, the oil tank is connected to the fuel injector 41 through a fuel pipe, and the fuel injection pump is connected to the fuel pipe. Since it is necessary to press-fit the bushing of the fuel injector 41 after the seal ring 6 of the cylinder head is assembled, by setting the lubrication system 4, lubricating oil can be sprayed into the installation hole, so as to reduce the friction between the fuel injector bushing and the seal ring 6 during the subsequent press-fitting process and avoid the seal ring 6 being squeezed and deformed during the press-fitting.

[0047] Further, the lubrication system 4 further includes a first lifting drive member 42. The first lifting drive member 42 is provided to adjust the height of the fuel injector 41, thereby flexibly adjusting the distance between the fuel injector 41 and the mounting hole of the component to be installed, which has strong practicability. Optionally, the first lifting drive member 42 includes a first drive cylinder, and the cylinder rod of the first drive cylinder is fixedly connected to the fuel injector 41. The cylinder rod of the first drive cylinder expands and contracts relative to the cylinder block, which can realize the lifting of the fuel injector 41 relative to the positioning tray 22, thereby adjusting the distance between the fuel injector 41 and the component to be installed on the positioning tray 22.

[0048] This embodiment is not limited thereto. In addition to being set as the first drive cylinder, the first lifting drive member 42 can also be set as a linear servo module, an electric telescopic rod and other components.

[0049] In this embodiment, the lubrication system 4 further includes a third position detection member 43, and the third position detection member 43 is used to detect the lifting position of the fuel injector 41. Exemplarily, the third position detection member 43 is set as a position sensor.

[0050] In this embodiment, the feeding system 1 includes a feeding channel 12, a material distribution table 13 and a material distribution drive member 14. The material distribution table 13 has at least two feeding stations. The sealing ring 6 moves through the feeding channel 12 to the feeding station for the clamping member 32 to clamp. The material distribution drive member 14 is used to drive the material distribution table 13 to move, so that the discharging end of the feeding channel 12 can be switched between at least two feeding stations. Specifically, a vibrating feeder 11 is provided at the feeding end of the feeding channel 12. The sealing ring 6 to be fed is accommodated in the vibrating feeder 11. When the vibrating feeder 11 works, the sealing ring 6 inside is vibrated out, so that the sealing ring 6 moves through the feeding channel 12 to the feeding station of the material distribution table 13. When clamping the sealing ring 6, the robotic arm 31 drives the clamping member 32 to move above the feeding station, so that the clamping member 32 clamps the sealing ring 6 on the feeding station.

[0051] By providing the material distribution drive member 14, the material distribution table 13 can be driven to displace relative to the feeding channel 12, and then different feeding stations can be switched to the position directly opposite to the feeding channel 12, so that multiple sealing rings 6 can be placed on the material distribution table 13 at one time. Specifically, when one of the feeding stations is directly opposite to the feeding channel 12, the feeding work of the sealing ring 6 can be carried out, and the sealing rings 6 accommodated on the other feeding stations can be directly clamped by the clamping member 32, ensuring that the feeding and clamping work are carried out simultaneously.

[0052] Optionally, baffles (not shown) are provided on both sides of the feeding channel 12 in the direction opposite to its own extension direction. By providing the baffles, it can be avoided that the sealing ring 6 falls out of the feeding channel 12 during the passing process.

[0053] In this embodiment, the material distributing driving member 14 includes a material distributing driving cylinder. The vibrating feeder 11, the feeding channel 12 and the cylinder block of the material distributing driving cylinder are respectively fixed on the bench 15, and the cylinder rod of the material distributing driving cylinder is fixedly connected to the material distributing table 13. Specifically, the cylinder rod of the material distributing driving cylinder expands and contracts relative to the cylinder block, so that the material distributing table 13 can move relative to the feeding channel 12 along the expansion and contraction direction of the cylinder rod, that is, the movement of the material distributing table 13 can be realized, and the operation is convenient.

[0054] This embodiment is not limited thereto. In addition to being set as a material distributing driving cylinder, the material distributing driving member 14 can also be set as a linear servo module, an electric telescopic rod and other components.

[0055] Optionally, a feeding detection member 16 is further provided on the vibrating feeder 11. The feeding detection member 16 is used to detect the feeding state of the sealing ring 6 during the feeding process of the vibrating feeding member. Specifically, when the vibrating feeder 11 works, every time a sealing ring 6 is vibrated out, the feeding detection member 16 will detect the sealing ring 6. If the feeding detection member 16 does not detect that a feeding detection member 16 passes within a certain time range during the working process of the vibrating feeder 11, it proves that the vibrating feeder 11 is jammed or empty. At this time, the alarm information can be displayed through a buzzer, an alarm lamp or an external remote display screen, and the operator needs to check the inside of the vibrating feeder 11 in time.

[0056] Exemplarily, the feeding detection member 16 can be set as a grating type sensor.

[0057] Optionally, the feeding system 1 further includes a housing 17, and the housing 17 covers the vibrating feeder 11 and the feeding channel 12. The setting of the housing 17 can prevent the vibrating feeder 11 and the feeding channel 12 from being exposed to the external environment, so as to protect the vibrating feeder 11 and the feeding channel 12.

[0058] In this embodiment, the clamping member 32 includes a clamping head 321, a plurality of first jaws 322 and a plurality of second jaws 323. Among them, the clamping head 321 is arranged on the robotic arm 31, the plurality of first jaws 322 are arranged on the clamping head 321, the plurality of first jaws 322 move along the radial and axial directions of the clamping head 321, and are used to jointly support the inner peripheral wall of the sealing ring 6. The plurality of second jaws 323 are arranged on the clamping head 321, the plurality of second jaws 323 move along the radial and axial directions of the clamping head 321, and are used to jointly clamp the outer peripheral wall of the sealing ring 6. Specifically in this embodiment, when clamping the sealing ring 6, the plurality of first jaws 322 do not act. After the plurality of second jaws 323 adjust their positions, they are located outside the sealing ring 6 and jointly clamp the outer peripheral wall of the sealing ring 6, thereby reliably clamping the sealing ring 6. Subsequently, the robotic arm 31 drives the clamping member 32 holding the sealing ring 6 to move above the material separation table 13. The plurality of second jaws 323 maintain the clamping of the outer side of the sealing ring 6 and send the sealing ring 6 into the installation hole. When the sealing ring 6 descends to the position of the annular groove in the installation hole, the plurality of first jaws 322 act, jointly support the inner peripheral wall of the sealing ring 6 to support the sealing ring 6 from the inside. The plurality of first jaws 322 retract along the axial direction of the clamping head 321 and disengage from the clamping of the outer side of the sealing ring 6. Next, the plurality of first jaws 322 continue to move radially outward along the clamping head 321, pushing against the inner peripheral wall of the sealing ring 6 to push the inner peripheral wall of the sealing ring 6 into the annular groove. At this time, most of the sealing ring 6 has entered the annular groove. To ensure the reliable installation of the sealing ring 6, next, the plurality of first jaws 322 move radially inward along the clamping head 321, disengaging from the contact with the sealing ring 6. After the robotic arm 31 drives the clamping member 32 to rise a certain distance, the plurality of second jaws 323 extend axially outward along the clamping head 321 again and move radially inward along the clamping head 321 until the plurality of second jaws 323 are located inside the sealing ring 6. Subsequently, the plurality of second jaws 323 move radially outward along the clamping head 321 again until they contact the inner peripheral wall of the sealing ring 6. At this time, the robotic arm 31 controls the rotation of the clamping head 321 so that the plurality of second jaws 323 can evenly press the inner peripheral wall of the sealing ring 6, completely pressing the inner peripheral wall of the sealing ring 6 into the annular groove to achieve the reliable installation of the sealing ring 6. After completing the above actions, the plurality of first jaws 322 move radially inward along the clamping head 321, disengaging from the contact with the sealing ring 6. The robotic arm 31 drives the clamping member 32 to rise, extending the first jaws 322 out of the installation hole, thereby completing the assembly of one sealing ring 6.

[0059] In some alternative embodiments, when clamping the sealing ring 6, after the plurality of first jaws 322 adjust their positions, they penetrate into the inside of the sealing ring 6 and jointly support the inner peripheral wall of the sealing ring 6, that is, adopt the method of inner support and outer clamping to reliably and effectively clamp the sealing ring 6, ensure that the sealing ring 6 maintains a certain shape and does not undergo excessive deformation, facilitating subsequent installation into the installation hole.

[0060] Exemplarily, in this embodiment, two clamping members 32 are provided on a robotic arm 31, which can simultaneously clamp and install two sealing rings 6. For the cylinder head, six mounting holes are provided. The robotic arm 31 reciprocates and moves in three cycles, and each of the two clamping members 32 clamps one sealing ring 6, so that the sequential assembly of six sealing rings 6 can be achieved.

[0061] Exemplarily, the number of the first clamping heads 321 and the number of the second clamping heads 321 are respectively set to three in this embodiment.

[0062] Exemplarily, a first movement driving member and a second movement driving member are provided on the clamping head 321. Among them, the first movement driving member is used to drive a plurality of first clamping jaws 322 to move along the radial and axial directions of the clamping head 321, and the second movement driving member is used to drive a plurality of second clamping jaws 323 to move along the radial and axial directions of the clamping head 321. Optionally, the first movement driving member includes a first radial movement cylinder and a first axial movement cylinder. The first radial movement cylinder is used to drive the first clamping jaws 322 to move along the radial direction of the clamping head 321, and the first axial movement cylinder is used to drive the first clamping jaws 322 to move along the axial direction of the clamping head 321. The second movement driving member includes a second radial movement cylinder and a second axial movement cylinder. The second radial movement cylinder is used to drive the second clamping jaws 323 to move along the radial direction of the clamping head 321, and the second axial movement cylinder is used to drive the second clamping jaws 323 to move along the axial direction of the clamping head 321.

[0063] Further, a profiling head 324 for abutting against the inner peripheral wall of the sealing ring 6 is provided on the first clamping jaw 322, and the end surface of the profiling head 324 abutting against the inner peripheral wall of the sealing ring 6 is set to be arc-shaped. By providing the profiling head 324, the arc-shaped end surface of the profiling head 324 abutting against the inner peripheral wall of the sealing ring 6 can better fit the inner peripheral wall of the sealing ring 6, so as to more reliably and effectively support the inside of the sealing ring 6.

[0064] Further, an embedding groove 3241 is formed on the end surface of the profiling head 324 abutting against the inner peripheral wall of the sealing ring 6, and the embedding groove 3241 is used to accommodate a part of the inner peripheral wall of the sealing ring 6. By providing the embedding groove 3241, the sealing ring 6 can be better fixed by a plurality of first clamping jaws 322, ensuring reliable and stable inner support of the sealing ring 6.

[0065] In this embodiment, a first position detecting member 25 is further provided on the clamping head 321, and the first position detecting member 25 is used to detect the positions of the first clamping jaws 322 and the second clamping jaws 323. Exemplarily, the first position detecting member 25 is set as a position sensor.

[0066] In this embodiment, the positioning system 2 includes a positioning bracket 21, a positioning tray 22, and a second lifting driving member 23. The positioning tray 22 is disposed on the positioning bracket 21. The positioning tray 22 is provided with a positioning boss 221 for plugging into the component to be installed. The second lifting driving member 23 is disposed between the positioning tray 22 and the positioning bracket 21 and is used to drive the positioning tray 22 to lift on the positioning bracket 21. Specifically, the component to be installed is provided with a positioning hole corresponding to the positioning boss 221. When the component to be installed is placed on the positioning tray 22 and placed in place, the positioning boss 221 can be plugged into the positioning hole to ensure reliable positioning of the component to be installed. The setting of the second lifting driving member 23 is used to adjust the height of the positioning tray 22 to facilitate the assembly of the clamping head 321.

[0067] Specifically, the second lifting driving member 23 includes a second driving cylinder. The cylinder body of the second driving cylinder is fixedly connected to the positioning bracket 21, and the cylinder rod of the second driving cylinder is fixedly connected to the positioning tray 22. The cylinder rod of the second driving cylinder expands and contracts relative to the cylinder body, enabling the positioning tray 22 to lift on the positioning bracket 21, thereby realizing the height adjustment of the positioning tray 22.

[0068] This embodiment is not limited thereto. In addition to being set as a second driving cylinder, the second lifting driving member 23 can also be set as a linear servo module, an electric telescopic rod, or other components.

[0069] Specifically, a guide shaft 222 is disposed on the positioning tray 22 along its own lifting direction. A guide hole (not shown) is correspondingly provided on the positioning bracket 21, and the guide shaft 222 slidably passes through the guide hole. The cooperation between the guide shaft 222 and the guide hole can provide guidance for the lifting movement of the positioning tray 22, strictly ensuring the lifting direction of the positioning tray 22 and ensuring reliable and stable position adjustment of the positioning tray 22.

[0070] Optionally, a plurality of guide shafts 222 and guide holes are provided in one-to-one correspondence.

[0071] Specifically, the guide shaft 222 passes through the guide hole. A limit head 223 is provided at the passing end of the guide shaft 222. The limit head 223 is adapted to abut against the positioning bracket 21 when the positioning tray 22 rises relative to the positioning bracket 21 to the limit position. By providing the limit head 223, the upward limit of the positioning tray 22 can be achieved, avoiding the guide shaft 222 coming out of the guide hole due to excessive upward movement of the positioning tray 22.

[0072] In this embodiment, a second position detection member 24 is further provided on the clamping head 321. The second position detection member 24 is used to detect the lifting position of the positioning tray 22. Exemplarily, the second position detection member 24 is set as a position sensor.

[0073] In this embodiment, the sealing ring assembly device further includes a detection system 5, which is used to detect the installation state of the sealing ring 6. Specifically, the detection system 5 can detect the installation state of the sealing ring 6 in the installation hole, determine whether the sealing ring 6 is installed in place, and ensure the installation in place and reliability.

[0074] In this embodiment, the detection system 5 includes a video recording mechanism 51, an imaging detection mechanism, and an alarm mechanism. Among them, the video recording mechanism 51 is used to record images of the installed sealing ring 6, the imaging detection mechanism is used to detect the images of the sealing ring 6 recorded, and the alarm mechanism is adapted to alarm when the imaging detection mechanism detects that the installation of the sealing ring 6 is abnormal. Specifically, the video recording mechanism 51 is communicatively connected to the imaging detection mechanism, and the imaging detection mechanism is communicatively connected to the alarm mechanism. After the sealing ring 6 is assembled, the video recording mechanism 51 obtains the image of the assembled sealing ring 6 and sends the image information to the imaging detection mechanism. A preset image of the assembled sealing ring 6 is preset in the imaging detection mechanism. The obtained image is compared with the preset image. If it is detected that the difference between the obtained image and the preset image is greater than the threshold, the imaging detection mechanism sends an alarm message to the alarm mechanism to control the alarm mechanism to alarm, and timely reminds the operator to check and adjust the sealing ring 6 with assembly problems.

[0075] Exemplarily, the alarm mechanism can be set to be able to alarm through a buzzer, an alarm lamp, or an external remote display screen to display the alarm information, thereby timely reminding the operator to check and adjust the sealing ring 6 with assembly problems.

[0076] Optionally, the video recording mechanism 51 is set as a camera.

[0079] Optionally, the third lifting drive member 53 includes a third drive cylinder. The cylinder body of the third drive cylinder is arranged on the integrated frame 52, and the cylinder rod of the third drive cylinder is fixedly connected to the video recording mechanism 51.
