[0017] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-13 The present invention provides a technical solution: the equipment includes an operating table 1, an O-ring assembly station 3, a plastic body feeding station 4, a check ring assembly station 5, a check ring pressing station 6, an inner plug assembly station 8, a basket assembly station 9, a nut feeding station 10, a nut tightening station 11, and a finished product discharge station 12. Each of the 10 stations is equipped with a vibratory feeder 13. A turntable 2 is installed on the top of the operating table 1. The O-ring assembly station 3 is located above the operating table 1 and on one side of the turntable 2. The plastic body feeding station 4 is located on one side of the O-ring assembly station 3. The anti-reverse ring assembly station 5 is located on the side of the plastic body feeding station 4 away from the O-ring assembly station 3. The anti-reverse ring pressing station 6 is located on one side of the anti-reverse ring assembly station 5. A first inspection station 7 is set on one side of the anti-reverse ring pressing station 6.

[0019] The controller starts the vibratory feeder 13, which sorts the O-ring body 304, plastic body, anti-lock ring body, inner plug, basket, nut and other parts into a uniform shape through vibration and conveys them to the material picking end of each station to prepare for subsequent assembly.

[0020] O-ring assembly station 3 includes a first servo module 301 set above the operating table 1. A first cylinder 302 is fixedly installed on one side of the first servo module 301. A spreading gripper 303 is set at the output end of the first cylinder 302. An O-ring body 304 is sleeved on the outside of the spreading gripper 303.

[0021] The plastic body loading station 4 includes a second servo module 401 set above the operating table 1. A support frame 405 is fixedly installed on one side of the second servo module 401. A pneumatic gripper 402 is fixedly installed on one side of the support frame 405. A loading detection mechanism 403 is fixedly installed on one side of the support frame 405. A first CCD vision detection module 404 is fixedly installed above the operating table 1.

[0022] The second servo module 401 drives the pneumatic gripper 402 to move to the picking end of the vibratory feeder 13, gripping the prepared plastic body and moving it above the spreading gripper 303. Then, the second servo module 401 drives the gripper to transfer the plastic body to the turntable 2. The first servo module 301 drives the first cylinder 302 and the spreading gripper 303 to move to the picking end of the vibratory feeder 13. The spreading gripper 303 grabs the O-ring body 304 and actively spreads it open, so that the inner diameter of the O-ring is larger than the assembly outer diameter of the plastic body. The first servo module 301 moves the expanded O-ring to the O-ring assembly slot on the bottom outer surface of the plastic body. Then, the expanded gripper 303 retracts, and the O-ring fits into the assembly slot under its own elasticity, completing the assembly of the O-ring. The feeding detection mechanism 403 at the support frame 405 is used to monitor whether the plastic body is stably placed in the station of the turntable 2 to avoid empty clamping or placement deviation. The first CCD vision detection module 404 can take pictures of the assembled O-ring and plastic body in the fixture.

[0023] It should be noted that the feeding detection mechanism 403 is a camera used to detect whether the plastic body is placed in the designated position on the turntable 2.

[0024] The anti-reverse ring assembly station 5 includes a third servo module 501 set above the operating table 1. A second cylinder 502 is installed on one side of the third servo module 501. The output end of the second cylinder 502 is connected to a pneumatic suction nozzle 503. An upper lifting mechanism 504 is fixedly connected to the top of the operating table 1 below the pneumatic suction nozzle 503. A first pressure sensor 505 is installed on the top of the upper lifting mechanism 504.

[0025] The anti-reverse ring vibratory plate 13 delivers the anti-reverse ring to the plastic body above the upper lifting mechanism 504. The third servo module 501 drives the second cylinder 502 and the pneumatic suction nozzle 503 at the end to move above the plastic component. The pneumatic suction nozzle 503 at the end sucks up the anti-reverse ring and drives the anti-reverse ring to move above the turntable 2 fixture. At this time, the upper lifting mechanism 504 rises from below the plastic body to provide a support platform for the plastic body. The second cylinder 502 drives the pneumatic suction nozzle 503 to descend. At this time, the anti-reverse ring loses its adsorption with the pneumatic suction nozzle 503, and the anti-reverse ring will be initially placed in the corresponding installation position of the plastic body.

[0026] The anti-reverse ring pressing station 6 includes a first bracket 601 fixedly connected above the operating table 1. A third cylinder 602 is fixedly installed on the outside of the first bracket 601. A pressing rod 603 is connected to the output end of the third cylinder 602. A second pressure sensor 604 is fixedly connected to the bottom of the pressing rod 603. A first displacement sensor 605 is provided on one side of the third cylinder 602.

[0027] The third cylinder 602 on the first bracket 601 drives the pressing rod 603 to move downward, forcibly pressing the pre-placed anti-reverse ring body into the preset assembly groove of the plastic body. The second pressure sensor 604 at the bottom of the pressing rod 603 monitors the pressure in real time. The controller determines whether there is any abnormality in the pressing process through the feedback of the second pressure sensor 604. The first displacement sensor 605 is used to monitor the moving distance of the pressing rod 603.

[0028] The first testing station 7 includes a second bracket 701 fixedly installed above the operating table 1. A fourth cylinder 703 is installed on one side of the second bracket 701. A second displacement sensor 702 is installed on one side of the fourth cylinder 703. A testing probe 704 is installed at the bottom of the fourth cylinder 703.

[0029] The fourth cylinder 703 on the second bracket 701 drives the detection probe 704 to move downward. The detection probe 704 contacts the surface of the anti-reverse ring. At the same time, the second displacement sensor 702 detects the downward displacement of the probe 704 in real time. The displacement data is used to determine whether the pressing depth of the anti-reverse ring meets the design requirements.

[0030] The inner plug assembly station 8 includes a fourth servo module 801 fixedly connected to the top of the operating table 1. The inner plug assembly station 8 is located on the side of the first detection station 7 away from the anti-reverse ring pressing station 6. The flower basket assembly station 9 is located on the side of the inner plug assembly station 8. The flower basket assembly station 9 includes a fifth servo module 901 fixedly connected to the top of the operating table 1.

[0031] Flower basket assembly station 9: Flower baskets are fed by vibratory feeder 13. Inner plug assembly station 8: Inner plugs are also fed by vibratory feeder 13. After the test is completed, the probe is reset. Turntable 2 rotates to transfer the plastic body to inner plug assembly station 8. The pick-and-place mechanism in the fourth servo module 801 and the pick-and-place mechanism in the fifth servo module 901 move the inner plug and flower basket to the designated position respectively, and then complete the assembly of the flower basket and inner plug, and then assemble them into the designated position of the plastic body.

[0032] The nut loading station 10 is located on the side of the basket assembly station 9 away from the inner plug assembly station 8. The nut loading station 10 includes a sixth servo module 1001 fixedly connected to the top of the operating table 1.

[0033] The nut screwing station 11 is located on one side of the nut loading station 10. The nut screwing station 11 includes a seventh servo module 1101 fixedly connected to the top of the operating table 1. A servo motor 1102 is installed on one side of the seventh servo module 1101. A mechanical gripper 1103 is connected to the output end of the servo motor 1102. A torque sensor 1104 is installed on one side of the outside of the servo motor 1102. A laser displacement sensor 1105 is installed on the other side of the outside of the servo motor 1102. A finished product discharge station 12 is set between the nut screwing station 11 and the O-ring assembly station 3.

[0034] The vibratory feeder 13 for nuts is activated, transporting the nuts to the predetermined material-picking waiting position. The controller controls the sixth servo module 1001 to drive its picking mechanism to move to the material-picking waiting position and grab a nut, precisely moving it to the position of the corresponding fixture above the turntable 2. The turntable 2 is precisely positioned, and the assembled anti-reverse ring, inner plug, and basket plastic body remain at this station. The sixth servo module 1001 places the nut on top of its plastic body. The turntable 2 rotates the workpiece with the pre-placed nut to the nut-screwing station 11. The controller controls the seventh servo module 1101 to drive the servo motor 1102 and mechanical gripper 1103 to move above the nut, and the mechanical gripper 1103... 03 Align and clamp the nut on the workpiece. Servo motor 1102 starts and drives mechanical gripper 1103 to start rotating. During the tightening process, as the nut is screwed in, its top will gradually descend. Laser displacement sensor 1105 continuously monitors this descent displacement. Torque sensor 1104 directly measures the real-time torque value on the output shaft of servo motor 1102. After the nut is tightened, turntable 2 rotates and transfers the workpiece with all parts assembled to finished product discharge station 12. Finished product discharge station 12 is used to remove the finished workpiece with all parts assembled from the fixture on turntable 2, and at the same time distinguish between qualified and unqualified products, and transfer them to finished product storage area and waste area respectively.

[0035] It should be noted that the above servo modules are all driven by servo motor 1102 and are linear motion actuators with precision guide rails. Their core function is to drive the end effector to achieve precise spatial linear displacement.

[0036] Connector assembly method: Step 1: Equipment initialization and material preparation. The controller starts the vibratory feeders 13 at each station to organize and transport the parts. At the same time, each component of the equipment performs a reset and self-check to ensure that the equipment is in a ready-to-work state.

[0037] Step 2: Plastic body loading and O-ring assembly. The second servo module 401 transfers the plastic body to the fixture of the turntable 2 for testing. The first servo module 301 drives the gripper 303 to open and grab the O-ring body 304 to complete the O-ring assembly and check the assembly status.

[0038] Furthermore, if the first CCD vision inspection module 404 detects that the O-ring has fallen off or broken due to excessive deformation after bonding, the turntable 2 will stop running. The plastic body needs to be marked, and the batch size problem of the plastic bodies in the same batch needs to be checked. If the problem exists, the machine needs to be stopped and the material replaced.

[0039] Furthermore, if the O-ring still cannot be fitted into the assembly slot of the plastic body after the plastic body is replaced, it is determined that the inner diameter of the O-ring does not match the outer diameter of the assembly slot of the plastic body. The O-ring of the corresponding specification should be replaced and the assembly operation should be performed again.

[0040] Step 3: Anti-reverse ring assembly and press-fit inspection. Turntable 2 drives the workpiece to the anti-reverse ring assembly station 5. The anti-reverse ring is pre-placed in the plastic body mounting position. Turntable 2 drives the workpiece to the anti-reverse ring pressing station 6. The third cylinder 602 drives the pressing rod 603 to press down. The second displacement sensor 702 detects the pressing depth of the anti-reverse ring.

[0041] Specifically, when the anti-reverse ring is pre-installed inside the plastic body, the first pressure sensor 505 is used to detect the reaction force after the plastic body contacts the anti-reverse ring. The reaction force value is set with a standard parameter value by the controller. The distance that the upper lifting mechanism 504 rises is set with a fixed parameter value by the controller. At this time, the upper lifting mechanism 504 is used to push the plastic body to rise and make precise contact with the lower end face of the anti-reverse ring.

[0042] It should be noted that the lifting mechanism 504 is a mechanical structure that achieves vertical lifting through the cooperation of a power source, a lifting rod, a limiting column, and other structures. It is existing technology and will not be elaborated on here.

[0043] Furthermore, if the upper lifting mechanism 504 pushes the plastic body to the standard height, and the first pressure sensor 505 detects a support pressure value lower than the standard parameter value, it indicates that the plastic body is not in effective contact with the anti-reverse ring. It can be determined that the pneumatic nozzle 503 of the anti-reverse ring has not moved to the preset docking position, and there is a spatial misalignment between the two, preventing them from contacting each other. At this time, it is necessary to recalibrate and correct the position of the pneumatic nozzle 503 and the anti-reverse ring, and reinstall the anti-reverse ring. If the first pressure sensor 505 detects a support pressure value that is still lower than the standard parameter value, it can be determined that the size of the anti-reverse ring is too small, and there is no significant resistance when it is pre-installed in the groove of the plastic body. That is, after assembly, the stability is insufficient, and the anti-reverse ring needs to be inspected and replaced.

[0044] If the actual support pressure value detected by the first pressure sensor 505 is higher than the standard parameter value, it can be determined that the plastic body is tilted and offset in the fixture, and the coaxiality of the assembly groove and the anti-reverse ring is seriously out of standard. After lifting, the two are in an eccentric contact state, generating lateral extrusion force. At this time, it is necessary to correct the position of the plastic body, restore the anti-reverse ring to its initial state, and then the upper lifting mechanism 504 drives the plastic body to rise and then descend to the initial position. The rising and falling space does not leave the fixture, so that the plastic body can automatically correct its posture during the movement. If the actual support pressure value detected by the first pressure sensor 505 is still higher than the standard parameter value after the plastic body is corrected, it can be determined that the size of the anti-reverse ring is too large and cannot be embedded in the installation position of the plastic body during pre-placement. It is necessary to check the size of the anti-reverse ring and replace it.

[0045] If the actual support pressure value detected by the first pressure sensor 505 is equal to the standard parameter value, it indicates that there is no abnormality in the pre-installation of the anti-lock ring and the plastic body.

[0046] After the anti-reverse ring is pre-installed with the plastic body, the third cylinder 602 drives the pressing rod 603 to move downward, forcibly pressing the pre-placed anti-reverse ring body into the preset assembly groove of the plastic body. The pressing stroke is detected in real time by the first displacement sensor 605, and the pressure is monitored in real time by the second pressure sensor 604 at the bottom of the pressing rod 603, so as to realize the status monitoring of the pressing process.

[0047] Specifically, the moving distance of the pressing rod 603 is preset by the controller, and the pressure value of the second pressure sensor 604 is set by the controller to P, while the actual pressure value is P1.

[0048] Scenario 1: When the moving distance of the press rod 603 reaches the preset value, and the actual pressure value P1 detected by the second pressure sensor 604 is equal to the preset value P, and there is no sudden increase or decrease in pressure throughout the process, it indicates that the anti-reverse ring and the plastic body are not deformed or damaged during the press-fitting process.

[0049] Scenario 2: When the moving distance of the pressing rod 603 reaches half or more of the preset value, and the actual pressure value P1 detected by the second pressure sensor 604 exceeds the preset value P, it indicates that the anti-reverse ring and the plastic body are stuck during the pressing process, causing a sudden increase in pressure. At this time, it can be determined that the inner wall thickness of the plastic body is too thick, and the pressure of the anti-reverse ring increases suddenly during pressing. At this time, it is necessary to control the third cylinder 602 to drive the pressing rod 603 to rise, release the rigid extrusion, and avoid continuous damage to the anti-reverse ring and the plastic body. After that, stop the machine and mark the plastic shell for inspection. If it is found that the thickness of the plastic body is indeed too thick, causing a large resistance in the movement stroke of the anti-reverse ring, and the plastic body has obvious deformation, then mark the workpiece as unqualified and transfer it to the rejection area, and do not repeat the pressing.

[0050] Scenario 3: When the moving distance of the pressing rod 603 reaches the preset value, but the actual pressure value P1 detected by the second pressure sensor 604 is lower than the preset value P, the controller controls the pressing rod 603 to maintain its pressure for a period of time and observes whether the pressure rises. If the pressure still does not change, and if the pressing rod 603 moves down a certain distance again, and its moving distance exceeds the preset value, but the actual pressure value P1 is higher than the preset value P, it can be determined that the thickness of the plastic body is too thin, resulting in a large gap between it and the anti-reverse ring. Pressing needs to be stopped immediately and the plastic body needs to be removed directly.

[0051] Step 4: Assembly of the inner plug and flower basket. Turntable 2 drives qualified workpieces to the inner plug assembly station 8 and the flower basket assembly station 9 in sequence. The fourth servo module 801 and the fifth servo module 901 drive the pick-and-place mechanism to grab the inner plug and flower basket respectively, and assemble them precisely into the designated position of the plastic body to complete the assembly of the inner plug and flower basket.

[0052] Step 5: Nut loading and tightening. The workpiece flows to the nut loading station 10. The sixth servo module 1001 drives the material picking mechanism to grab the nut and place it above the threaded hole of the plastic body. The turntable 2 drives the workpiece to the nut tightening station 11. The servo motor 1102 starts to drive the nut to rotate and tighten.

[0053] Specifically, during the screwing process, the standard torque value of the servo motor 1102 set by the controller is N, the torque sensor 1104 collects the torque value N1 in real time, the standard displacement of the nut descent set by the controller is S, and the actual displacement of the nut descent monitored by the laser displacement sensor 1105 is S1.

[0054] If the torque sensor 1104 collects a torque value N1 in real time that exceeds the standard torque value N to tighten the nut, and the actual nut descent displacement S1 monitored by the laser displacement sensor 1105 does not reach the standard nut descent displacement S, it indicates that the torque is too high and the displacement distance is stuck. Combined with the pressure data in step three, if the actual pressure value P1 in step three exceeds the preset value P, and the machine is stopped to clean the debris inside the plastic shell, it can be determined that there is debris residue in the thread groove where the plastic shell and the nut need to be connected, and it needs to be cleaned. If the phenomenon of excessive torque and stuck displacement distance still occurs after cleaning, it indicates that the plastic body deformed due to excessive pressure in step three, and the nut cannot be screwed in normally. At this time, the workpiece is directly marked as a defective product and transferred to the rejection area.

[0055] If the torque value N1 collected by the torque sensor 1104 in real time is lower than the standard torque value N, the actual nut descent displacement S1 monitored by the laser displacement sensor 1105 does not reach the standard nut descent displacement S. At this time, it is necessary to check whether the nut has abnormal thread size and does not match the size of the plastic shell, mark the workpiece as unqualified, remove it, check the incoming batch, and replace it with a nut with matching thread specifications.

[0056] If, after the nut is replaced, the servo motor 1102 tightens the nut with the standard torque value N, and the actual nut descent displacement S1 monitored by the laser displacement sensor 1105 is equal to the standard nut descent displacement S, then the nut is tightened normally and the assembly is normal.

[0057] Step Six: Finished Product Discharge. Turntable 2 drives the workpieces that have completed all assembly processes to the finished product discharge station 12. The discharge mechanism sorts qualified and unqualified products according to the feedback information from each inspection station and transfers them to the corresponding areas.
