Description

Technical Field

[0001] This application relates to the technical field of connector assembly, and in particular to a fuel pipe connector assembly machine and assembly process. Background Technology

[0002] Automotive fuel lines are pipes used to transport fuel in a vehicle's fuel system. Adjacent fuel lines and fuel lines are generally connected to fuel-using equipment via connectors.

[0003] In related technologies, such as Figure 1 The disclosed fuel pipe connector includes a housing 11 and an outer sealing ring 12 sleeved on the outside of the housing 11. Inside the housing 11, a first inner sealing ring 13, a partition ring 14, a second inner sealing ring 15, and a positioning ring 16 are installed in sequence, wherein the positioning ring 16 is located on the side of the second inner sealing ring 15 facing the opening of the housing 11 for connecting the fuel pipe.

[0004] The traditional method for assembling the aforementioned fuel pipe connector involves workers manually installing the first inner sealing ring, the separator ring, the second inner sealing ring, and the positioning ring into the housing one by one. This method is time-consuming, labor-intensive, and inefficient. Furthermore, after the connector is assembled, since the first inner sealing ring, the separator ring, the second inner sealing ring, and the positioning ring are all located inside the housing, it is impossible to lubricate the outer surfaces of the first and second inner sealing rings. It is also difficult to determine whether the structure is installed correctly, which hinders the control of finished product quality and requires improvement. Summary of the Invention

[0005] In order to improve assembly efficiency, facilitate lubrication of the first and second inner sealing rings, and control the quality of finished products, this application provides a fuel pipe connector assembly machine and assembly process.

[0006] Firstly, the fuel pipe connector assembly machine provided in this application adopts the following technical solution:

[0007] A fuel pipe connector assembly machine includes a frame and a turntable rotatably mounted on the frame. A plurality of support seats are spaced apart along the circumference of the turntable, and a column is connected to the support seats for a first inner sealing ring, a separator ring, a second inner sealing ring and a positioning ring to be fitted together.

[0008] The first ring-fitting mechanism is used to fit the positioning ring into the column;

[0009] The first ring-fitting mechanism is used to fit the second inner sealing ring into the column and to deliver lubricating oil to the inner wall of the second inner sealing ring.

[0010] The second ring-fitting mechanism is used to insert the separator ring into the column;

[0011] The second ring fitting mechanism is used to fit the first inner sealing ring into the column and to deliver lubricating oil to the inner wall of the first inner sealing ring;

[0012] The first testing mechanism is used to test whether the column is fully equipped with the positioning ring, the second inner sealing ring, the separator ring and the first inner sealing ring.

[0013] The oil injection mechanism is used to deliver lubricating oil to the outer walls of the first inner sealing ring and the second inner sealing ring;

[0014] The housing assembly mechanism is used to mount the housing onto the column so that the first inner sealing ring, the partition ring, the second inner sealing ring, and the positioning ring extend into the housing;

[0015] The outer ring mounting mechanism is used to fit the outer sealing ring onto the outside of the housing.

[0016] The discharge mechanism includes a main discharge frame, a good product discharge component and a defective product discharge component set on the main discharge frame. The good product discharge component is used to send the assembled qualified finished products into the good product collection track, and the defective product discharge component is used to remove the waste material sleeved on the column and send the waste material into the defective product collection box.

[0017] The rotating mechanism is used to drive the turntable to rotate circumferentially so that the column can pass through the first ring mounting mechanism, the first ring mounting mechanism, the second ring mounting mechanism, the second ring mounting mechanism, the first detection mechanism, the oil injection mechanism, the shell mounting mechanism, the outer ring installation mechanism, and the discharge mechanism in sequence.

[0018] By adopting the above technical solution, during the assembly of the fuel pipe connector, the turntable rotates continuously under the action of the rotating mechanism, causing the column to pass sequentially through the first ring mounting mechanism, the first inner sealing ring mounting mechanism, the second ring mounting mechanism, the second inner sealing ring mounting mechanism, the first detection mechanism, the oil injection mechanism, the housing mounting mechanism, the outer ring installation mechanism, and the discharge mechanism. This allows the positioning ring, the second inner sealing ring, the separator ring, and the first inner sealing ring to be sequentially fitted onto the column, then snapped into the housing fitted onto the column, and finally the outer sealing ring to be fitted onto the outside of the housing, thus achieving rapid assembly of the fuel pipe connector. This assembly method is fully automated, eliminating the need for manual assembly operations by workers, saving time and labor, and offering a high degree of automation and assembly efficiency.

[0019] The first inspection mechanism can detect whether the positioning ring, second inner sealing ring, separator ring, and first inner sealing ring are completely installed on the column to prevent omissions. If the first inspection mechanism determines that the installation is complete, the subsequent assembly process continues; if the first inspection mechanism determines that the installation is incomplete, the subsequent assembly process is paused, that is, the housing is not installed on the column where the positioning ring, second inner sealing ring, separator ring, and first inner sealing ring are not completely installed, so that the defective product discharge assembly can remove the waste material from the column. This application is equipped with an automatic inspection mechanism that can accurately determine whether the four rings are installed in place and automatically screen them at the discharge mechanism according to the finished product condition, which is beneficial for controlling the quality of the finished product during assembly.

[0020] Furthermore, the first ring-assembly mechanism delivers lubricating oil to the inner wall of the second inner sealing ring, and the second ring-assembly mechanism delivers lubricating oil to the inner wall of the first inner sealing ring, thus lubricating both the inner walls of the first and second inner sealing rings. The oil-filling mechanism delivers lubricating oil to the outer walls of both the first and second inner sealing rings, ensuring their lubrication. Both internal and external lubrication of the first and second inner sealing rings are performed before they are installed into the housing, making operation convenient.

[0021] Optionally, the first ring-loading mechanism includes a ring-loading frame, a movable frame slidably mounted on the ring-loading frame, a first vertical pusher for driving the movable frame to move vertically, a first horizontal pusher for driving the movable frame to move horizontally toward the turntable, an oil supply pipe fixed on the movable frame, a push plate sleeved on the oil supply pipe, and a ring-pushing component for driving the push plate to move vertically. The circumferential sidewall of the oil supply pipe is provided with a plurality of oil supply holes. The frame is provided with an inner ring material channel for horizontally transmitting the second inner sealing ring. The oil supply pipe can be moved to directly above the outlet of the inner ring material channel.

[0022] By adopting the above technical solution, when installing the second inner sealing ring, after the second inner sealing ring is moved directly below the oil supply pipe, the first vertical pusher drives the movable frame to move downward, allowing the oil supply pipe to pass into the second inner sealing ring. At this time, the oil supply hole will be aligned with the inner wall of the second inner sealing ring. Then, lubricating oil is pumped into the oil supply pipe, and the lubricating oil will flow along the oil supply hole to the second inner sealing ring to lubricate its inner wall. Next, the first vertical pusher drives the movable frame to move upward, and then the first horizontal pusher drives the movable frame to move towards the turntable until the second inner sealing ring is moved directly above the adjacent column. Finally, the pusher drives the push plate to move downward, and the push plate will push the second sealing ring from the oil supply pipe into the column, thereby realizing the installation of the second inner sealing ring. In this application, the lubrication and feeding of the second inner sealing ring are carried out in one mechanism, which is beneficial to improving the integration of the equipment and reducing the space occupied.

[0023] Optionally, the first detection mechanism includes a first detection frame, a first detection block vertically slidably disposed on the first detection frame, a first detection power component disposed on the first detection frame for driving the first detection block to move vertically, and a first test block vertically slidably disposed in the first detection block. The first detection block is provided with a first detection space for the first test block to extend vertically into, and a first sensor for sensing whether the first test block exists in the first detection space. The bottom surface of the first test block is provided with a clearance groove for the column to extend vertically into, and the inner diameter of the clearance groove is smaller than the outer diameter of the first inner sealing ring, the partition ring, the second inner sealing ring, and the positioning ring.

[0024] By employing the above technical solution, when detecting whether the column is fully equipped with the four rings—positioning ring, second inner sealing ring, separator ring, and first inner sealing ring—the first detection power component drives the first detection block downwards. The first test block moves downwards synchronously, causing the column to vertically penetrate the clearance groove and the bottom of the first test block to abut against the rings fitted on the column. As the first detection block continues to move downwards, it cannot move further due to the resistance of the rings and will move upwards relative to the column. If all four rings are fully fitted on the column, the first test block will move into the first detection space. After the first sensor detects the presence of the first test block, it will send a signal to the subsequent mechanism to continue operation. If any rings are missing from the column, the upward movement distance of the first test block will be insufficient to allow it to enter the first detection space. The first sensor will not detect the presence of the first test block and will send a signal to the subsequent mechanism to stop operation, thus preventing the formation of defective products. This method offers good detection results and high accuracy.

[0025] Optionally, the oil injection mechanism includes an oil injection frame, an oil injection pneumatic gripper mounted on the oil injection frame, and oil injection blocks connected to different gripper bodies of the oil injection pneumatic gripper. An oil injection cavity for accommodating the column is formed between two oil injection blocks. The oil injection blocks are provided with oil injection holes for lubricating oil input and two rows of oil guide holes connecting the oil injection holes and the oil injection cavity. One row of oil guide holes is aligned with the first inner sealing ring, and the other row of oil guide holes is aligned with the second inner sealing ring.

[0026] By adopting the above technical solution, during oil injection, the two oil injection blocks are first controlled to move towards each other by the oil injection pneumatic gripper, so that one row of oil guide holes is aligned with the first inner sealing ring and the other row of oil guide holes is aligned with the second inner sealing ring. Then, lubricating oil is pumped into the oil injection hole, and the oil will seep into the outer side of the first and second inner sealing rings along the oil guide holes, thereby achieving synchronous lubrication of the first and second inner sealing rings during one oil pumping, resulting in high oil injection efficiency.

[0027] Optionally, the shell loading mechanism includes a shell loading frame, a rotary pneumatic gripper for clamping and rotating the shell, a shell loading vertical pusher for driving the rotary pneumatic gripper to move vertically, and a shell loading horizontal pusher for driving the rotary pneumatic gripper to move horizontally toward the turntable. The frame is provided with a shell feeding channel for horizontally transporting the shell. One side of the shell feeding channel is provided with an upper-opening installation channel. The gripper body of the rotary pneumatic gripper can extend into the installation channel. The shell loading frame is provided with a pusher for pushing the shell toward the installation channel.

[0028] By adopting the above technical solution, when installing the shell, after the shell is moved along the shell feeding channel to be aligned with the pusher, the pusher will first push the shell into the installation channel; then the shell loading vertical pusher, shell loading horizontal pusher and rotating pneumatic gripper will be activated, so that the rotating pneumatic gripper will first clamp the shell out of the installation channel and rotate it at a certain angle, and then move the shell to the top of the adjacent column. Then the shell loading vertical pusher will push down, so that the shell is fitted onto the column and the fitting is completed.

[0029] Optionally, the outer ring mounting mechanism includes an outer ring mounting frame, a bracket connected to the outer ring mounting frame, a rotary cylinder for driving the bracket to rotate circumferentially, a flat pusher for driving the bracket to move vertically, and a multi-claw finger cylinder mounted on the bracket. The bottom of the claws of the multi-claw finger cylinder is fixed with sharp claws. The frame is provided with an outer ring material channel for horizontally conveying the outer sealing ring. The sharp claws can move to above the outlet of the outer ring material channel and extend into the inner side of the outer sealing ring. An upper ring plate is commonly fitted on the outer side of each of the sharp claws. An upper ring power component is provided on the bracket for driving the upper ring plate to push the outer sealing ring away from the sharp claws.

[0030] By adopting the above technical solution, when installing the outer sealing ring, first control the jaws of the multi-jaw finger cylinder to close, then extend each pointed claw into the inside of the outer sealing ring, and then control the jaws of the multi-jaw finger cylinder to open. The outer sealing ring will then expand outwards under force, making it easier to subsequently fit onto the housing. This installation method eliminates the need for workers to manually open the outer sealing ring, making it convenient and efficient.

[0031] Optionally, the frame is provided with a fixed plate located inside the turntable. The fixed plate is provided with a second detection mechanism at the position corresponding to the outer ring mounting mechanism. The second detection mechanism includes a second detection frame, a pressure cylinder provided on the second detection frame, and a second detection block connected to the piston rod of the pressure cylinder. The bottom of the second detection block is provided with an arc-shaped groove adapted to the shape of the housing.

[0032] By adopting the above technical solution, before installing the outer sealing ring, the second detection block is first moved down by a pressure cylinder. If the column of the turntable corresponding to the outer ring mounting mechanism is already fitted with the housing, the second detection block will collide with the housing. After the sensor in the pressure cylinder detects the pressure, it will send a running signal to the outer ring mounting mechanism. If the column of the turntable corresponding to the outer ring mounting mechanism is not fitted with the housing, the second detection block will not collide with the housing, the sensor in the pressure cylinder will not detect the pressure, and it will send a stop signal to the outer ring mounting mechanism. Whether the outer ring mounting mechanism operates is related to whether the housing is installed in place, which helps to reduce process waste and improve assembly efficiency.

[0033] Optionally, the fixed plate is provided with a third detection mechanism located between the second detection mechanism and the discharge mechanism. The third detection mechanism includes a third detection frame, a third detection block slidably disposed on the third detection frame, a third detection cylinder for driving the third detection block to move vertically, and a third test block vertically inserted in the third detection block. The third detection block is provided with a third detection space for the third test block to extend vertically into, and a third sensor for sensing whether the third test block exists in the third detection space. When the column with the housing moves to the third detection mechanism, the third test block is located directly above the annular groove of the housing for fitting the outer sealing ring.

[0034] By adopting the above technical solution, the third inspection mechanism can detect whether an outer sealing ring is installed on the shell, and its specific principle is similar to that of the first inspection mechanism. If the third inspection mechanism detects that the outer sealing ring is installed, it means that the output finished product is a good product; if the third inspection mechanism detects that the outer sealing ring is not installed, it means that the output finished product is a defective product. In practical applications, the detection data of the third inspection mechanism can be correlated with the discharge mechanism to facilitate automatic screening of good and defective products.

[0035] Optionally, the defective product discharge assembly includes a defective product discharge rack, a defective product pneumatic gripper mounted on the defective product discharge rack, defective product discharge blocks respectively disposed on different gripper bodies of the defective product pneumatic gripper, and a defective product power component for driving the vertical movement of the defective product discharge rack; a plurality of discharge hooks are integrally formed on the bottom of the two opposite sides of the defective product discharge blocks, and a plurality of extension plates are provided on the circumferential sidewall of the positioning ring, the distance between the extension plates and the central axis of the positioning ring being greater than the diameter of the column; a plurality of limiting grooves with bottom openings are opened on the positioning ring, and a limiting block is provided on the column that is respectively inserted and engaged with each limiting groove.

[0036] By adopting the above technical solution, for columns that are not fully fitted with the four rings, after the column is moved to the discharge mechanism, the defective product discharge block is first driven to move towards the column, so that each discharge hook abuts against the underside of the extension piece. Then, the defective product power component drives the defective product discharge rack to move upward, causing the discharge hooks to lift the extension piece upward, thereby pushing the positioning ring, the second inner sealing ring, the separator ring, and the first inner sealing ring away from the column, thus achieving automatic removal of waste material from the column. The limiting block and the limiting groove cooperate to prevent the positioning ring from rotating when fitted onto the column, which is beneficial for the subsequent alignment of the discharge hooks and the extension piece.

[0037] Secondly, the fuel pipe connector assembly process provided in this application adopts the following technical solution:

[0038] A fuel pipe connector assembly process, using the fuel pipe assembly machine as described above, includes the following steps.

[0039] S1. Activate the rotating mechanism to make the turntable drive each support and column to rotate circumferentially;

[0040] S2, Fitting the positioning ring: The positioning ring is fitted into the column through the first ring fitting mechanism;

[0041] S3. Install the second inner sealing ring. The second inner sealing ring is inserted into the column through the first ring installation mechanism, and lubricating oil is output to the inner wall of the second inner sealing ring.

[0042] S4. Install the partition ring, and insert the partition ring into the column through the second mounting mechanism;

[0043] S5. Install the first inner sealing ring, and use the second ring-installing mechanism to fit the first inner sealing ring into the column, and output lubricating oil to the inner wall of the first inner sealing ring;

[0044] S6. The first detection mechanism operates to detect whether the positioning ring, the second inner sealing ring, the separator ring, and the first inner sealing ring are completely installed on the column. If "yes", the subsequent actions of the first detection mechanism are set to run normally; if "no", the actions between the first detection mechanism and the discharge mechanism are set to pause.

[0045] S7. The oil injection mechanism operates, outputting lubricating oil to the outer walls of the first and second sealing rings;

[0046] S8. Install the housing. The housing is fitted onto the column using the housing mounting mechanism, so that the first inner sealing ring, the partition ring, the second inner sealing ring, and the positioning ring extend into the housing.

[0047] S9. Install the outer sealing ring, and fit the outer sealing ring onto the outside of the housing through the outer ring installation mechanism;

[0048] S10. Finished product discharge: qualified products are sent to the good product collection track by the good product discharge component, and unqualified products are removed from the column by the defective product discharge component and the waste material falls into the defective product collection box.

[0049] In summary, this application includes at least one of the following beneficial technical effects:

[0050] 1. When assembling the fuel pipe connector, first, place the positioning ring, the second inner sealing ring, the separator ring, and the first inner sealing ring on the column. While placing them, lubricate the inner walls of the second and first inner sealing rings. Then, lubricate the outer walls of the second and first inner sealing rings through the oil injection mechanism. Next, place the housing on the column so that the above four rings can be installed in the housing. Finally, place the outer sealing ring on the housing. This achieves automated assembly of the housing, with high assembly efficiency, good product quality, and convenient oil injection.

[0051] 2. The first detection mechanism can determine whether the four rings are completely installed on the column. The second detection mechanism can determine whether the shell is installed on the column before the outer sealing ring is installed. The third detection mechanism can determine whether the outer sealing ring is installed in place. In actual application, the above detection mechanisms can be associated with the discharge mechanism to facilitate automatic screening of good and defective products according to the finished product condition.

[0052] 3. If the four rings are not fully fitted on the column, the operation between the first detection mechanism and the discharge mechanism will stop to save processes and improve efficiency. After the column is moved to the discharge mechanism, the discharge hook can push the positioning ring and the ring above it away from the column, thereby realizing the rapid removal of waste.

[0083] The following is in conjunction with the appendix Figure 1-13 This application will be described in further detail.

[0084] This application discloses a fuel pipe connector assembly machine, which is used to assemble such... Figure 1 The fuel line connector shown.

[0085] Reference Figure 2 , Figure 3The fuel pipe connector assembly machine includes a frame 2, a turntable 21 rotatably mounted on the frame 2, an initial position detection mechanism 22 mounted on the frame 2, a first ring mounting mechanism 23, a first ring mounting mechanism 24, a second ring mounting mechanism 25, a second ring mounting mechanism 26, a first detection mechanism 27, an oil injection mechanism 28, a shell mounting mechanism 29, an outer ring mounting mechanism 3, a discharge mechanism 4, and a rotating mechanism 5. The rotating mechanism 5 drives the turntable 21 to rotate circumferentially. A fixed plate 6 located inside the turntable 21 is fixed on the frame 2. A second detection mechanism 61 and a third detection mechanism 62 are provided on the fixed plate 6. The second detection mechanism 61 is located at the position corresponding to the outer ring mounting mechanism 3, and the third detection mechanism 62 is located between the second detection mechanism 61 and the discharge mechanism 4.

[0086] Reference Figure 3 , Figure 4 Several support seats 211 are arranged circumferentially above the turntable 21, and each support seat 211 is connected to a column 212. The column 212 can be fitted together by the first inner sealing ring 13, the partition ring 14, the second inner sealing ring 15, and the positioning ring 16. Specifically, in this embodiment, the column 212 is installed on the support seat 211 by vertical insertion. The rotating mechanism 5 can be a power motor (not shown in the figure) connected to a reduction gearbox.

[0087] Reference Figure 4 The initial position detection mechanism 22 includes an initial position detection frame 221, an initial position cylinder 222 mounted on the initial position detection frame 221, an initial position slider 223 fixedly connected to the piston rod of the initial position cylinder 222, and an initial position test block 224 slidably passing through the initial position slider 223. The piston rod of the initial position cylinder 222 is horizontally oriented towards the turntable 21. The initial position slider 223 is provided with an initial position test space 225 for the initial position test block 224 to slide into, and an initial position sensor 226 for sensing whether the initial position test block 224 has moved into the initial position test space 225. When the piston rod of the initial position cylinder 222 extends, the initial position slider 223 and the initial position test block 224 move horizontally toward the turntable 21. If a column 212 is inserted into the support 211 adjacent to the initial position test mechanism, the initial position test block 224 will collide with the column 212 and move horizontally relative to the initial position slider 223, causing the initial position test block 224 to move into the initial position test space 225. After the initial position sensor 226 senses the presence of the initial position test block 224, it will send a running signal to the first ring assembly mechanism 23 to facilitate the orderly unfolding of the assembly action. It should be noted that, in order to achieve automatic reset of the initial position test block 224, an elastic element such as a spring can also be set between the initial position test block 224 and the initial position slider 223.

[0088] Reference Figure 5The first ring-loading mechanism 23 includes a ring-loading frame 231 fixedly connected to the frame 2, a ring-loading block 232 slidably disposed on the ring-loading frame 231, a ring-loading pneumatic gripper 233 disposed on the ring-loading block 232 for clamping or releasing the positioning ring 16, a ring-loading vertical pusher 234 for driving the ring-loading block 232 to move vertically, and a ring-loading horizontal pusher 235 for driving the ring-loading block 232 to move horizontally toward the turntable 21. In this embodiment, the ring-loading vertical pusher 234 and the ring-loading horizontal pusher 235 are preferably cylinders, and their specific connection methods are prior art, which will not be described in detail here. The frame 2 is provided with a ring feeding channel 236 for horizontally transmitting the positioning ring 16. One end of the ring feeding channel 236 is connected to a vibrating disk containing the positioning ring 16, and the other end is provided with an opening for the ring-loading pneumatic gripper 233 to extend into. When the positioning ring 16 is assembled, the pneumatic gripper 233 can clamp the positioning ring 16 from the ring feeding channel 236 and fit it into the column 212.

The first detection mechanism 27 can detect whether the four rings—positioning ring 16, second inner sealing ring 15, separator ring 14, and first inner sealing ring 13—are completely fitted on the column 212. Its detection principle is the same as that of the initial position detection mechanism 22, and will not be described in detail here. If the rings are completely fitted, the subsequent mechanisms will operate normally; if the rings are not completely fitted, the subsequent actions will stop, that is, the housing 11 will not be installed on the column 212 where the rings are not completely fitted.

The gripper of the rotary cylinder 33 can extend into the installation channel 296 to grip the housing 11 and control the housing 11 to rotate horizontally by 90°, so that the annular groove on the housing 11 for the outer sealing ring 12 is rotated to the side of the housing 11 away from the center of the turntable 21. Then, the housing 11 is vertically inserted into the column 212 so that the first inner sealing ring 13, the separating ring 14, the second inner sealing ring 15, and the positioning ring 16 automatically extend into the housing 11.

When the pressure cylinder 612 drives the second detection block 613 to move down, if the housing 11 is installed on the column 212 below the second detection block 613, the second detection block 613 will contact the housing 11. After detecting the pressure, the pressure cylinder 612 will send a signal to the outer ring mounting mechanism 3 to inform the outer ring mounting mechanism 3 that the outer sealing ring 12 can be installed. If the housing 11 is not installed on the column 212 below the second detection block 613, the pressure cylinder 612 will not detect the pressure, and the outer ring mounting mechanism 3 does not need to operate.

One end of the outer ring feed channel 36 is connected to the vibrating plate containing the outer sealing ring 12, and the other end has an opening for the insertion of the claws 351. When the multi-claw finger cylinder 35 is working, the converging claws 351 can extend into the inner side of the outer sealing ring 12 and, after expansion, drive the outer sealing ring 12 to deform, thereby increasing the inner diameter of the outer sealing ring 12.

[0100] Reference Figure 10 , Figure 11 Furthermore, an upper ring plate 37 is commonly fitted on the outer side of each claw 351. An upper ring power component 38 is provided on the bracket 32 ​​to drive the upper ring plate 37 to push the outer sealing ring 12 away from the claw 351. The upper ring power component 38 is preferably a cylinder. After the outer sealing ring 12 opens, the bracket 32 ​​is first rotated 90° by the rotary cylinder 33, so that the axial direction of the outer sealing ring 12 is adjusted to the horizontal direction. Then, the bracket 32 ​​is driven to move towards the turntable 21 by the horizontal pushing force component. Finally, the upper ring power component 38 drives the upper ring plate 37 to push the outer sealing ring 12 away from the claw, so that the outer sealing ring 12 can be fitted onto the corresponding housing 11.

When the column 212 containing the housing 11 moves to the third detection mechanism 62, the third test block 624 is located directly above the annular groove of the housing 11 for fitting the outer sealing ring 12. The third detection mechanism 62 can detect whether the outer sealing ring 12 is fitted on the housing 11. Its detection principle is similar to that of the initial detection mechanism 22, and will not be described in detail here.

Two extension pieces 162 extend outward from the circumferential sidewall of the positioning ring 16. The distance between the extension pieces 162 and the central axis of the positioning ring 16 is greater than the maximum diameter of the column 212. When collecting defective products, the discharge hook 435 can move to abut against the lower side of the extension piece 162 and push the extension piece 162 upward under the drive of the defective product power component 434, so as to remove the waste such as the positioning ring 16 sleeved on the column 212.

[0105] It should be noted that since the cylinder installation and connection method is relatively conventional and is not the main improvement point of this application, the description of the cylinder installation method mentioned above has not been elaborated.

[0106] The implementation principle of a fuel pipe connector assembly machine according to an embodiment of this application is as follows: When assembling the fuel pipe connector, the turntable 21 will continuously rotate under the action of the rotating mechanism 5, so that the column 212 passes through the first ring mounting mechanism 23, the first ring mounting mechanism 24, the second ring mounting mechanism 25, the second ring mounting mechanism 26, the first detection mechanism 27, the oil injection mechanism 28, the housing mounting mechanism 29, the second detection mechanism 61, the outer ring mounting mechanism 3, the third detection mechanism 62, and the discharge mechanism 4 in sequence, so that the positioning ring 16, the second inner sealing ring 15, the separating ring 14, and the first inner sealing ring 13 are first sequentially fitted onto the column 212, and then inserted into the housing 11 fitted onto the column 212. After the second detection mechanism 61 detects the housing 11, the outer sealing ring 12 will be fitted onto the outside of the housing 11, thereby realizing the rapid assembly of the fuel pipe connector. Finally, the assembled good product is sent to the good product collection rail 45 by the discharge mechanism 4, and the waste such as the positioning ring 16 fitted onto the column 212 is removed to the defective product collection box 46. The above assembly method eliminates the need for workers to manually perform the assembly step by step, saving time and effort, and achieving a high degree of automation and assembly efficiency.

[0107] The first inspection mechanism 27, the second inspection mechanism 61, and the third inspection mechanism 62 can be used to determine whether each ring in the connector is installed correctly. If any ring is missing, the housing 11 is not installed, which facilitates the differentiation between good and defective products and helps to accurately control product quality. When the first ring mounting mechanism 24 is working, it can lubricate the inner wall of the second inner sealing ring 15. When the second ring mounting mechanism 26 is working, it can lubricate the inner wall of the first inner sealing ring 13. The oil injection mechanism 28 can lubricate the outer walls of the first inner sealing ring 13 and the second inner sealing ring 15. This application adopts the method of first injecting oil for lubrication and then installing the housing 11, which makes the operation more convenient.

[0108] This application also discloses a fuel pipe connector assembly process, including the following steps:

[0113] S5. Install the first inner sealing ring 13, and use the second ring-installing mechanism 26 to insert the first inner sealing ring 13 into the column 212, and output lubricating oil to the inner wall of the first inner sealing ring 13.

[0114] S6. The first detection mechanism 27 operates to detect whether the positioning ring 16, the second inner sealing ring 15, the separator ring 14 and the first inner sealing ring 13 are completely installed on the column 212. If "yes", the subsequent actions of the first detection mechanism 27 are set to run normally; if "no", the actions between the first detection mechanism 27 and the discharge mechanism 4 are set to pause.

[0115] S7, the oil injection mechanism 28 works, outputting lubricating oil to the outer walls of the first and second sealing rings;

[0116] S8. Install housing 11 and use housing mounting mechanism 29 to mount housing 11 onto column 212 so that the first inner sealing ring 13, the partition ring 14, the second inner sealing ring 15 and the positioning ring 16 extend into housing 11.

[0117] S9. Fit the outer sealing ring 12, and fit the outer sealing ring 12 into the outside of the housing 11 through the outer ring mounting mechanism 3;

[0118] S10. Finished product discharge: qualified products are sent to the good product collection track 45 by the good product discharge component 42, and unqualified products are removed from the column 212 by the defective product discharge component 43 and the waste material falls into the defective product collection box 46.
