Description

Technical Field

[0001] This disclosure relates to the field of liquid-cooled quick-connect connector technology, and in particular to a liquid-cooled quick-connect connector female assembly device. Background Technology

[0002] Universal Quick Connect (UQD) is a standardized fluid connection device designed for high-density heat dissipation scenarios, widely used in liquid cooling environments such as data centers, AI computing servers, and energy storage systems. It connects cooling pipes to cold plates or manifolds quickly, safely, and leak-free, enabling efficient coolant flow and online maintenance. Its core advantage lies in its bidirectional self-sealing valve structure, allowing for insertion and removal under pressure and automatic sealing upon disconnection to prevent leakage and protect electronic equipment. It also supports blind insertion or manual insertion, significantly improving operational efficiency, especially suitable for high-density deployments and automation requirements. Mainstream types include blind insertion (UQDB) and manual insertion (UQD), with materials ranging from stainless steel and engineering plastics. Sealing materials often use EPDM or fluororubber to ensure temperature, pressure, and corrosion resistance. With the OCP (Open Compute Project) promoting standardization, UQD is becoming an indispensable "invisible hub" in liquid cooling systems.

[0003] Liquid-cooled quick-connect connectors typically consist of two parts: a female connector and a male connector. The female connector has a complex internal structure with more than 10 components. Due to the small size of the female connector itself, and the even smaller components assembled on it, assembly is difficult and requires manual assembly, resulting in low production efficiency. Summary of the Invention

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a liquid-cooled quick-connect female connector assembly device that improves the production efficiency of female connectors.

[0005] The purpose of this disclosure is achieved through the following technical solution: A liquid-cooled quick-connect female connector assembly device includes: a circulating guide rail, a female connector feeding device, an inner sealing assembly device, a first spring assembly device, a washer pin assembly device, a pull cap assembly device, a C-ring assembly device, a female connector flipping device, an outer sealing assembly device, a movable valve assembly device, a second spring assembly device, a fixed valve assembly device, a key ring assembly device, and a pressing assembly device. The circulating guide rail is equipped with multiple transfer fixtures. The circulating guide rail has sequentially arranged stations for: female head seat loading, inner seal assembly, first spring assembly, washer PIN pin assembly, salad cap assembly, C-ring assembly, female head flipping, outer seal assembly, movable valve assembly, second spring assembly, fixed valve assembly, key ring assembly, and pressing assembly. Female head seat loading devices, inner seal assembly devices, first spring assembly devices, washer PIN pin assembly devices, salad cap assembly devices, C-ring assembly devices, female head flipping devices, outer seal assembly devices, movable valve assembly devices, second spring assembly devices, fixed valve assembly devices, key ring assembly devices, and pressing assembly devices are located at their respective stations. The female head seat loading device is used to transfer the female head seat to the transfer fixtures. The inner seal assembly device is used to install the inner seal ring inside the first end of the female head seat. The first spring assembly device is used to sleeve the first spring on the outside of the first end of the female head seat. The washer PIN pin assembly device is used to sleeve the washer on the outside of the first end of the female head seat. The first end of the female connector is externally connected to a first spring and has a pin hole for inserting a PIN pin into the female connector; a salad cap assembly device is used to fasten the salad cap onto the first end of the female connector, and simultaneously encloses the first spring, washer, and PIN pin therein; a C-clasp assembly device is used to install the C-clasp into the annular groove of the salad cap and clamp it between the salad cap and the female connector; a female connector flipping device is used to flip the second end of the female connector upwards; an outer sealing assembly device is used to install the outer sealing ring into the annular groove of the second end of the female connector; a movable The movable valve assembly device is used to insert the movable valve from the second end of the female head seat and pass through the inner sealing ring; the second spring assembly device is used to insert the second spring from the second end of the female head seat and pass through the movable valve; the fixed valve assembly device is used to assemble the fixed valve with the fixed sealing ring; the key ring assembly device is used to assemble the key ring with the fixed valve with the fixed sealing ring installed to form an assembly; the pressing assembly device is used to press the assembly from the second end of the female head seat and pass through the second spring to form the liquid-cooled quick-connect female head.

[0006] Compared with the prior art, this disclosure has at least the following advantages: Through the collaboration of 13 dedicated workstations and circulating guide rails, the entire assembly process of liquid-cooled quick-connect female connectors, from bulk materials to finished products, is fully covered. This replaces the traditional manual step-by-step assembly mode, significantly reducing the proportion of manual intervention. A single machine can achieve parallel operation of multiple workstations, resulting in a significant improvement in production efficiency compared to semi-automated assembly lines. The workstation layout adopts a "forward assembly - flip-and-reverse assembly" approach. First, the assembly of components such as the inner seal, spring, and pull-tab cap at the first end of the female connector is completed. Then, the workstation posture is switched via a female connector flipping device to complete the assembly of components such as the outer seal and movable valve at the second end. This perfectly matches the structural assembly logic of the liquid-cooled female connector, avoiding process interference and significantly reducing the rate of component collisions and misalignments during assembly. Multiple sets of transfer fixtures mounted on the circulating guide rails can circulate throughout all workstations without the need for additional loading and unloading transfer mechanisms. This simplifies the overall machine transmission structure and ensures that the female connector positioning reference is consistent across all workstations, effectively controlling the coaxiality tolerance of each process and ensuring that the core sealing performance of the liquid-cooled female connector meets standards.

[0012] Please see Figure 1 This is a schematic diagram of the structure of a liquid-cooled quick-connect female connector assembly device according to an embodiment of the present disclosure.

[0013] One embodiment of the liquid-cooled quick-connect female connector assembly equipment 1 includes a circulating guide rail 1A, a female connector feeding device 1B, an inner sealing assembly device 1C, a first spring assembly device 1D, a washer pin assembly device 1E, a salad cap assembly device 1F, a C-ring assembly device 1G, a female connector flipping device 1H, an outer sealing assembly device 1I, a movable valve assembly device 1J, a second spring assembly device 1K, a fixed valve assembly device 1L, a key ring assembly device 1M, and a pressing assembly device 1N; the circulating guide rail 1A is provided with multiple transmission clamps 100, and the circulating guide rail 1A has a female connector feeding station, an inner sealing assembly station, a first spring assembly station, and a washer pin assembly station arranged sequentially. The assembly stations are as follows: female head assembly station, pull-tab assembly station, C-buckle assembly station, female head flipping station, outer seal assembly station, movable valve assembly station, second spring assembly station, fixed valve assembly station, key fob assembly station, and pressing assembly station; female head seat feeding device 1B, inner seal assembly device 1C, first spring assembly device 1D, washer PIN pin assembly device 1E, pull-tab assembly device 1F, C-buckle assembly device 1G, female head flipping device 1H, outer seal assembly device 1I, movable valve assembly device 1J, second spring assembly device 1K, fixed valve assembly device 1L, key fob assembly device 1M, and pressing assembly device 1N are located at their respective stations; female head seat feeding device 1B is used to feed the female head... The headstock is transferred to the transfer fixture 100; the inner sealing assembly device 1C is used to install the inner sealing ring inside the first end of the female headstock; the first spring assembly device 1D is used to sleeve the first spring on the outside of the first end of the female headstock; the washer PIN pin assembly device 1E is used to sleeve the washer on the outside of the first end of the female headstock, with the first spring abutting against it, and to pass the PIN pin through the pin hole of the female headstock; the salad cap assembly device 1F is used to fasten the salad cap to the first end of the female headstock, and simultaneously wrap the first spring, washer and PIN pin inside it; the C-buckle assembly device 1G is used to install the C-buckle in the annular groove of the salad cap, and clamp it between the salad cap and the female headstock; the female head flipping device 1H is used for... The second end of the female head seat is flipped upwards; the outer sealing assembly device 1I is used to install the outer sealing ring in the annular groove at the second end of the female head seat; the movable valve assembly device 1J is used to insert the movable valve from the second end of the female head seat and pass through the inner sealing ring; the second spring assembly device 1K is used to insert the second spring from the second end of the female head seat and pass through the movable valve; the fixed valve assembly device 1L is used to assemble the fixed valve with the fixed sealing ring; the key buckle assembly device 1M is used to assemble the key buckle with the fixed valve with the fixed sealing ring installed to form an assembly; the pressing assembly device 1N is used to press the assembly from the second end of the female head seat and pass through the second spring to form a liquid-cooled quick-connect female head.

[0014] In this embodiment, through the collaboration of 13 dedicated workstations and the circulating guide rail 1A, the entire assembly process of the liquid-cooled quick-connect female connector from bulk materials to finished product is fully covered, replacing the traditional manual step-by-step assembly mode, significantly reducing the proportion of manual intervention. A single machine can achieve parallel operation of multiple workstations, and the production efficiency is significantly improved compared to a semi-automated assembly line. Adopting a workstation layout of "forward assembly - flipping and reversing - reverse assembly," the assembly of components such as the inner seal, spring, and pull tab at the first end of the female connector is completed first. Then, the workstation posture is switched by the female connector flipping device 1H to complete the assembly of components such as the outer seal and movable valve at the second end. This perfectly matches the structural assembly logic of the liquid-cooled female connector, avoiding process interference and significantly reducing the rate of component collisions and misalignments during assembly. The multiple sets of transfer fixtures 100 mounted on the circulating guide rail 1A can circulate throughout all workstations without the need for additional loading and unloading transfer mechanisms. This simplifies the overall machine transmission structure and ensures that the female connector positioning reference is consistent across all workstations, effectively controlling the coaxiality tolerance of each process and ensuring that the sealing performance of the core of the liquid-cooled female connector meets the standards.

[0015] In one embodiment, please refer to Figure 2 The female head seat feeding device 1B includes a feeding conveying structure 10a and a feeding transfer structure 10b. Both the feeding conveying structure 10a and the feeding transfer structure 10b are located near the circulating guide rail 1A. The feeding conveying structure 10a is used to feed and convey the female head seat through a pallet, and the feeding transfer structure 10b is used to transfer the female head seat in the pallet to the transfer fixture 100.

[0016] In this embodiment, both the feeding conveyor structure 10a and the feeding transfer structure 10b are located adjacent to the circulating guide rail 1A, resulting in a compact spatial layout and shortening the physical distance of materials from the supply end to the assembly starting point. The feeding conveyor structure 10a uses pallets as carriers for orderly material feeding, while the feeding transfer structure 10b is responsible for quickly transferring workpieces to the transfer fixture 100. This relay design of "conveyor-transfer" ensures that the feeding cycle is precisely synchronized with the running cycle of the circulating guide rail 1A, avoiding equipment waiting or idling due to untimely material supply and guaranteeing continuous and stable production at 13 workstations.

[0017] The process of transferring the female head unit from the pallet to the transfer fixture 100 by the loading and transfer structure 10b is a controlled mechanical action, rather than manual placement. This ensures that each female head unit has a high degree of consistency in its posture, position, and orientation when it enters the initial station of the circulating guide rail 1A. Precise initial positioning provides a unified benchmark for the accurate execution of all subsequent processes such as inner seal assembly and first spring assembly, reducing assembly failures and product defects caused by loading deviations from the source.

[0018] Using pallets for loading and conveying female head units means that workpieces can be neatly arranged and oriented. This method facilitates integration with pre-installed automated warehousing or material handling systems, enabling standardized management of batch materials. Furthermore, by changing pallets of different specifications, it can quickly adapt to the loading requirements of different models of female head units, enhancing the equipment's flexible production capabilities and reducing the risk of workpieces bumping and scratching each other during transport.

[0019] The feeding and conveying structure 10a and the feeding and transferring structure 10b work together to simplify manual operation from "placing each piece onto the fixture" to "replenishing the entire tray of materials". This not only significantly reduces labor intensity and reduces fatigue errors that may be caused by repetitive manual operations, but also keeps operators away from moving parts such as the circulating guide rail 1A, significantly improving the safety level of the production site.

[0020] In one embodiment, please refer to Figure 3The inner sealing assembly device 1C includes an inner ring feeding structure 10c and an inner ring mounting structure 10d. The inner ring feeding structure 10c includes an inner ring feeding base 101, an inner ring feeding mixing tank 102, an inner ring pusher 103, and an inner ring feeder 104. The inner ring feeding mixing tank 102 is mounted on the inner ring feeding base 101 and is used for cutting and distributing the inner sealing ring. The inner ring feeder 104 includes an inner ring feeding platform 1041 and an inner ring feeding lifting motor 1042. The inner ring feeding lifting motor 1042 is connected to the inner ring feeding platform 1041 and the inner ring feeding lifting motor 1042. The inner ring feeding base 101 is connected to the inner ring feeding lifting motor 1042, whose lifting end is connected to the inner ring feeding platform 1041. The inner ring feeding platform 1041 has an inner ring feeding channel, which is connected to the discharge port of the inner ring feeding mixing tank 102. The outlet of the inner ring feeding channel faces the transmission clamp 100. The inner ring pusher 103 includes an inner ring pusher guide rail 1031, an inner ring pusher slider 1032, and an inner ring pusher plate 1033. The inner ring pusher guide rail 1031 is connected to the inner ring feeding base 101, and the inner ring pusher slider 1032 slides... The inner ring is slidably mounted on the inner ring pusher guide rail 1031. The inner ring pusher plate 1033 is connected to the inner ring pusher slider 1032. The inner ring pusher plate 1033 is slidably mounted in the inner ring feeding channel to push out the inner sealing ring. The inner ring mounting structure 10d includes an inner ring mounting frame 105, a first inner ring mounting lifting motor 106, a second inner ring mounting lifting motor 107, an inner ring mounting adapter plate 108, and an inner ring receiving platform 109. The inner ring mounting frame 105 is located at the female head seat loading station. The first inner ring mounting lifting motor 106 is mounted on the inner ring mounting frame. On 105, the lifting end of the first inner ring mounting lifting motor 106 is connected to the inner ring mounting adapter plate 108. The second inner ring mounting lifting motor 107 and the inner ring receiving platform 109 are both set on the inner ring mounting adapter plate 108. The inner ring receiving platform 109 is used to receive the inner sealing ring pushed out from the inner ring feeding channel. The inner ring receiving platform 109 has an inner ring mounting hole 109a. The lifting end of the second inner ring mounting lifting motor 107 is used to push the inner sealing ring on the inner ring receiving platform 109 into the first end of the female head seat through the inner ring mounting hole 109a.

[0021] In this embodiment, the inner ring feeding mixing tank 102 is responsible for cutting and distributing the bulk inner sealing rings, allowing them to enter the inner ring feeding channel in an orderly manner; the inner ring pusher 103 precisely pushes each sealing ring to the inner ring receiving platform 109; the inner ring mounting structure 10d then presses the sealing ring on the receiving platform into the first end of the female head seat through the inner ring mounting hole 109a. The entire device seamlessly connects the four links of "distribution-feeding-receiving-pressing", completely replacing manual handling and installation, and realizing unmanned operation of this process.

[0022] The inner ring feeding channel cooperates with the inner ring receiving platform 109 to keep the sealing ring horizontal during the pushing process, preventing it from flipping or tilting. The inner ring receiving platform 109 is provided with an inner ring mounting hole 109a for secondary positioning of the sealing ring, ensuring that it is coaxial with the inner hole of the female head seat. The second inner ring mounting lifting motor 107 pushes the sealing ring in vertically, and the installation depth is precisely controlled by the motor stroke, ensuring that the installation position of the sealing ring inside each female head seat is consistent, laying the foundation for the subsequent installation of the moving valve and the overall sealing performance. The first inner ring mounting lifting motor 106 is used to adjust the height of the inner ring receiving platform 109 to align with the inner ring feeding channel. During the process of pushing the inner sealing ring to the inner ring receiving platform 109, the lifting end of the second inner ring mounting lifting motor 107 moves downward synchronously to grab the inner sealing ring with an inner clamp before it falls into the inner ring mounting hole 109a. Then, when the transfer clamp 100 moves the female head seat below the inner ring receiving platform 109, the inner sealing ring is sent into the female head seat.

[0023] The inner ring feeding lifting motor 1042 can adjust the height of the inner ring feeding platform 1041, so that the outlet of the inner ring feeding channel can be precisely aligned with the inner ring receiving platform 109. This design not only compensates for assembly and manufacturing errors, but also allows the equipment to adapt to the height difference of different workstations by adjusting the feeding height when switching between different specifications of female heads, thus enhancing the flexible production capability of the equipment.

[0024] The inner ring feeding structure 10c and the inner ring mounting structure 10d are positioned on opposite sides and work together, resulting in a compact spatial layout and shortening the material transport path. The inner ring pusher plate 1033 is slidably set within the inner ring feeding channel, providing direct and reliable pushing action and reducing the risk of material jamming. The first inner ring mounting lifting motor 106 and the second inner ring mounting lifting motor 107 are responsible for the overall lifting of the adapter plate and the pressing of the sealing ring, respectively. The actions are clearly decomposed, do not interfere with each other, and facilitate debugging and maintenance.

[0025] In another embodiment, the second inner ring is equipped with a lifting motor 107 that presses multiple inner sealing rings into the first end of the female head seat one by one in multiple stages to form an internal multi-layer sealing structure. Specifically, two inner sealing rings are arranged in parallel inside the first end of the female head seat.

[0026] In another embodiment, there are two inner sealing assembly devices 1C, so that two inner sealing rings are provided inside the first end of the female head seat.

[0027] In one embodiment, please refer to Figure 4The first spring assembly device 1D includes a first spring feeding structure 10c and a first spring mounting structure 10d. The first spring feeding structure 10c includes a first spring feeding base 110 and a first spring vibrating feeder 111, which is disposed on the first spring feeding base 110 and is used for vibrating and distributing the first springs. The first spring mounting structure 10d includes a first spring mounting bracket 112, a first spring mounting lifting motor 113, a first spring mounting pushing motor 114, and a first pushing plate. 115 and the second pusher plate 116, the first spring mounting lifting motor 113 is mounted on the first spring mounting bracket 112, the lifting end of the first spring mounting lifting motor 113 is connected to the second pusher plate 116, the first pusher plate 115 and the second pusher plate 116 are arranged parallel to each other, the first pusher plate 115 has a first discharge hole 115a, the first discharge hole 115a is used to receive the first spring output by the first spring vibrating feeder 111, for example, one end of the vibration output rod of the first spring vibrating feeder 111 is embedded in the first discharge hole 115a. The second pusher plate 116 has a second discharge hole 116a, which is aligned with the first end of the female head seat. The first spring-mounted pusher motor 114 is connected to the second pusher plate 116. The telescopic end of the first spring-mounted pusher motor 114 is connected to the first pusher plate 115 so that the first spring in the first discharge hole 115a is sleeved on the outside of the first end of the female head seat through the second discharge hole 116a.

[0028] In this embodiment, the first spring vibratory feeder 111 vibrates and distributes the bulk springs, ensuring their orderly output into the first discharge hole 115a of the first pusher plate 115. The first spring mounting pusher motor 114 drives the first pusher plate 115 to translate, moving the springs to the second discharge hole 116a of the second pusher plate 116. Then, the first spring mounting lifting motor 113 drives the second pusher plate 116 to descend, inserting the springs along the outer side of the first end of the female head seat. This entire process seamlessly integrates with the inner sealing assembly process, achieving automatic spring feeding and installation, and eliminating potential problems such as skewing and jamming that may occur during manual spring installation.

[0029] The first pusher plate 115 and the second pusher plate 116 are arranged parallel to each other. The spring is always constrained within the discharge hole during the transfer process, preventing it from flipping or falling off. The second discharge hole 116a is aligned with the first end of the female head seat, ensuring that the spring is coaxial with the female head seat when it falls, and that the installation position is accurate. This provides a reliable positional reference for the subsequent contact and engagement of the washer and spring in the washer PIN pin assembly device 1E.

[0030] The first spring mounting pusher motor 114 is responsible for horizontally moving the spring, while the first spring mounting lifting motor 113 is responsible for vertically mounting the spring. These two actions are driven by independent motors and do not interfere with each other. This design simplifies the control logic, facilitates debugging and maintenance, reduces the risk of mechanical interference caused by combined actions, and improves the stability of equipment operation.

[0031] The first spring is sleeved on the outer side of the first end of the female head seat. The installation is performed vertically from above, avoiding the inner sealing ring already installed inside the female head seat. The stroke of the first spring installation lifting motor 113 can be precisely controlled to ensure that the spring stops immediately after being sleeved in place, without causing compression or displacement of the inner sealing ring, thus ensuring the assembly results of the previous process.

[0032] In one embodiment, please refer to Figure 5The washer PIN assembly device 1E includes a washer feeding structure 10e, a PIN feeding structure 10f, and a washer PIN mounting structure 10g. The washer feeding structure 10e includes a washer vibrating feeder 117 and a washer transfer table 118. The washer vibrating feeder 117 is used for vibrating and distributing the washers, and the outlet of the washer vibrating feeder 117 faces the washer transfer table 118, which is used to receive the washers. The PIN feeding structure 10f includes a PIN vibrating feeder 119 and a PIN lifting device. The device includes a PIN needle transfer table 121, a PIN needle pusher motor 122, and a PIN needle pusher rod 123. A PIN needle vibrating feeder 119 is used for vibrating and distributing PIN needles. A PIN needle lifting motor 120 is located between the outlet of the PIN needle vibrating feeder 119 and the circulating guide rail 1A. The lifting end of the PIN needle lifting motor 120 is connected to the PIN needle transfer table 121. The PIN needle transfer table 121 has multiple PIN needle transfer holes 121a, which are aligned with the needle holes of the female head seat. The telescopic end of the PIN pusher motor 122 is connected to the PIN pusher rod 123. The PIN pusher rod 123 passes through the PIN transfer hole 121a to insert the PIN into the pin hole of the female head seat. The washer PIN mounting structure 10g includes a washer PIN mounting bracket 124, a washer PIN mounting horizontal guide rail 125, a washer PIN mounting lifting motor 126, a washer PIN mounting rotary motor 127, and a washer PIN mounting mechanical claw 128. The washer PIN mounting horizontal guide rail 125 and the... The washer pin mounting bracket 124 is connected, and the washer pin mounting lifting motor 126 is slidably mounted on the washer pin mounting horizontal guide rail 125. The lifting end of the washer pin mounting lifting motor 126 is connected to the washer pin mounting rotary motor 127. The rotating shaft of the washer pin mounting rotary motor 127 is connected to the washer pin mounting mechanical claw 128. The washer pin mounting mechanical claw 128 is used to transfer the washer on the washer turntable 118 to the first spring of the female head seat, and to rotate the female head seat.

[0033] In this embodiment, the washer feeding structure 10e and the PIN feeding structure 10f operate independently. The washer vibrating feeder 117 feeds the washers to the washer transfer table 118, and the PIN vibrating feeder 119 feeds the PINs to the multiple transfer holes of the PIN transfer table 121. The mechanical claw in the washer PIN mounting structure 10g is responsible for transferring the washer to the first spring of the female head seat, while the PIN pusher 123 pushes the PIN into the pin hole of the female head seat. This parallel feeding and collaborative mounting design allows the assembly of the two parts to be completed in the same station, reducing the number of processes and shortening the production cycle.

[0034] After the washer pin mounting mechanical claw 128 picks up the washer from the washer transfer table 118, it precisely places the washer onto the outer side of the first end of the female head seat with the cooperation of the horizontal guide rail and the lifting motor, forming an abutment with the first spring. The gripping and placing actions of the mechanical claw are controlled by a rotary motor to ensure that the washer falls horizontally and is inserted coaxially, avoiding the problems of uneven spring compression or washer skew that may occur during manual installation, and ensuring consistent preload of the internal elastic structure.

[0035] The PIN transfer station 121 has multiple PIN transfer holes 121a, which are aligned with the pin holes of the female connector. The PIN pusher motor 122 drives the push rod to simultaneously push the PINs from the transfer holes into the pin holes of the female connector, ensuring that the insertion depth and direction of multiple PINs are consistent. This design avoids the sequence deviation that may be caused by inserting the pins one by one, ensures the fitting accuracy between the PINs and the pin holes of the female connector, and provides an accurate positioning basis for the subsequent snapping of the salad cap.

[0036] The washer PIN mounting rotary motor 127 not only adjusts the posture of the mechanical gripper when grasping the washer, but also rotates the female head seat when needed. This function allows the female head seat to be adjusted circumferentially as needed during washer and PIN mounting, ensuring precise alignment of the PIN and pin hole, and the washer and spring. It also provides the correct orientation of the female head seat for subsequent salad cap assembly processes, reducing the need for independent flipping or rotating mechanisms and simplifying the equipment structure.

[0037] The washer is fitted onto the outside of the first spring, and the installation action is performed axially along the first end of the female head seat. The PIN needle is inserted into the needle hole radially or axially, both of which avoid the inner sealing ring already installed inside the female head seat. The movement trajectory of the mechanical gripper is precisely controlled by the horizontal guide rail and the lifting motor, ensuring that the already installed first spring is not touched or disturbed during the transfer of the washer and the rotation of the female head seat, thus guaranteeing the assembly integrity of the preceding process.

[0038] In one embodiment, please refer to Figure 6The salad cap assembly device 1F includes a salad cap feeding structure 10h and a salad cap mounting structure 10i. The salad cap feeding structure 10h includes a salad cap vibrating feeder 129 and a salad cap transfer table 130. The salad cap vibrating feeder 129 is used for vibrating and distributing salad caps. The discharge port of the salad cap vibrating feeder 129 faces the salad cap transfer table 130, which is used to receive salad caps. The salad cap mounting structure 10i includes a salad cap mounting bracket 131 and a salad cap mounting... The system includes a horizontal guide rail 132, a salad cap mounting lifting motor 133, and a salad cap mounting mechanical claw 134. The horizontal guide rail 132 is connected to the salad cap mounting frame 131. The salad cap mounting lifting motor 133 is slidably mounted on the horizontal guide rail 132. The lifting end of the salad cap mounting lifting motor 133 is connected to the salad cap mounting mechanical claw 134. The salad cap mounting mechanical claw 134 is used to transfer the salad cap on the salad cap transfer table 130 and fasten it to the first end of the female head seat.

[0039] In this embodiment, the robotic gripper 134 picks up the salad cap from the salad cap transfer table 130, moves it along the horizontal guide rail to directly above the female head seat, and then, driven by the lifting motor, presses it vertically downward to fasten the salad cap onto the first end of the female head seat. This action completely encloses the previously installed inner sealing ring, first spring, washer, and PIN pin inside the salad cap, forming a closed inner assembly. After encapsulation, the relative positions of the components are locked, avoiding the risk of loosening or detachment during subsequent flipping or handling.

[0040] The salad cap is equipped with a lifting motor 133 that works in conjunction with a mechanical gripper to ensure the salad cap falls smoothly and vertically, with no tilting or impact during the fastening process. The gripping force and lifting speed of the mechanical gripper are adjustable, ensuring that the salad cap does not experience excessive pressure or scratching when it contacts the first spring and washer, protecting the elasticity of the spring and the surface quality of the washer. Simultaneously, the fastening depth of the salad cap is precisely controlled by the lifting stroke, reserving an accurate annular groove position for the installation of the C-ring in the next process.

[0041] Before the salad cap is snapped shut, the inner sealing ring is already embedded inside the first end of the female connector, the first spring is already sleeved on the outside of the first end, the washer is already abutting the spring, and the pin is already inserted into the pin hole. During salad cap installation, its inner cavity must simultaneously accommodate all of the above components, which places high demands on the precision of the installation positions of each component. This device, through the precise transfer and vertical pressing of the mechanical gripper, ensures that the salad cap is correctly aligned and smoothly snapped shut with each component, verifying the assembly quality of the preceding process. Simultaneously, it integrates the dispersed components into a unified whole, providing a consistent operating object for subsequent C-clasp assembly.

[0042] In one embodiment, please refer to the following: Figure 7 and Figure 8The C-ring assembly device 1G includes a C-ring feeding structure 10j, a C-ring pushing structure 10k, and a C-ring mounting structure 10l. The C-ring feeding structure 10j includes a C-ring vibrating feeder 135 and a C-ring feeding guide rod 136. The C-ring vibrating feeder 135 is used for vibrating and distributing the C-rings. A portion of the C-ring feeding guide rod 136 is embedded in the outlet of the C-ring vibrating feeder 135. The C-ring feeding guide rod 136 is used to sleeve the C-rings and vibrate them outwards. The C-ring pushing structure 10k includes a C-ring pushing platform 137, a C-ring pushing motor 138, and a C-ring pushing plate 139. The C-ring pushing platform 137 is located between the C-ring vibrating feeder 135 and the circulating guide rail 1A. The C-ring pushing platform 137 has interconnected C-ring receiving holes. 137a and C-button pusher groove 137b, the end of C-button feeding guide rod 136 away from C-button vibrating feeder 135 is located in C-button receiving hole 137a, C-button pusher motor 138 is connected to C-button pusher platform 137, the telescopic end of C-button pusher motor 138 is connected to C-button pusher plate 139, C-button pusher plate 139 is slidably disposed in C-button pusher groove 137b, C-button pusher plate 139 is used to push C-buttons out of C-button receiving hole 137a; C-button mounting structure 10l includes C-button mounting frame 140 and C-button transfer installer 141, C-button transfer installer 141 is disposed on C-button mounting frame 140, C-button transfer installer 141 is used to transfer C-buttons on C-button pusher plate 139 and install them in the annular groove of salad cover.

[0043] In this embodiment, the C-button vibratory feeder 135 vibrates and distributes bulk C-buttons, and the C-button feeding guide rod 136 orderly places and vibrates and conveys the C-buttons into the C-button receiving hole 137a of the C-button pushing platform 137. The C-button pushing motor 138 drives the pushing plate to push the C-buttons out of the receiving hole to the waiting position, and then the C-button transfer installer 141 grabs and installs them into the annular groove of the salad cover. The entire device seamlessly connects the four links of "distribution-directional conveying-pushing separation-transfer installation", completely replacing manual operation and solving the problem that C-buttons are difficult to automate due to their small size and easily deformable open structure.

[0044] The C-ring feeding guide rod 136 is embedded in the discharge port of the vibrating feeder. During vibration, the C-rings are successively mounted on the guide rod and conveyed forward with a uniform opening orientation and posture. This design avoids the C-rings from flipping, stacking, or getting stuck in the conveying pipe, ensuring that each C-ring is in the correct installation posture when it reaches the C-ring receiving hole 137a, providing a reliable prerequisite for subsequent material pushing and installation.

[0045] The C-ring pusher platform 137 is equipped with a C-ring receiving hole 137a and a C-ring pusher groove 137b. The end of the C-ring feeding guide rod 136 is located inside the receiving hole, allowing the C-rings to enter the receiving hole one by one. The C-ring pusher plate 139 slides in the pusher groove, pushing out only the bottom C-ring from the receiving hole with each movement, while the remaining C-rings remain on the guide rod waiting. This single-piece separation design ensures that only one C-ring is supplied for each installation, avoiding installation failures caused by multiple pieces being pushed out simultaneously.

[0046] The C-clip transfer installer 141 picks up the C-clip from the pusher plate and precisely installs it into the annular groove of the salad cover. After installation, the C-clip is clamped between the salad cover and the female connector, forming a mechanical lock that firmly fixes the salad cover to the first end of the female connector. This locking structure ensures that the previously encapsulated inner sealing ring, first spring, washer, and PIN pin will not loosen due to vibration or external force during subsequent flipping, handling, and use, thus guaranteeing the structural integrity and long-term reliability of the internal assembly.

[0047] After the C-ring is installed, the salad cover and the female connector form a rigid connection, and all internal parts of the first end of the female connector are reliably encapsulated. This provides a stable clamping and flipping foundation for the next process, the female connector flipping device 1H, ensuring that the internal parts of the female connector will not shift or fall off during the flipping process, so that the assembly process of the second end can proceed smoothly.

[0048] Furthermore, please refer to the following: Figure 7 and Figure 8 The C-buckle feeding structure 10j also includes a C-buckle feeding guide plate 142, which is connected to the C-buckle feeding guide rod 136. The C-buckle feeding guide plate 142 extends along the length of the C-buckle feeding guide rod 136 and is used to guide the opening of each C-buckle to the same direction.

[0049] In this embodiment, the C-ring feeding guide plate 142 extends along the length of the C-ring feeding guide rod 136. During the vibration conveying of the C-ring on the guide rod, its opening contacts the guide plate and is guided in the same direction. This ensures that when each C-ring reaches the C-ring receiving hole 137a, the opening orientation is completely consistent, providing a unified attitude reference for the pushing action of the C-ring pusher plate 139 and the gripping action of the C-ring transfer installer 141, avoiding installation misalignment or jamming caused by random opening orientation.

[0050] When installing the C-clip into the groove of the salad cap, its opening direction must correspond to the notch position of the groove. After the guide plate unifies the opening direction, the C-clip transfer installer 141 can be directly installed without additional circumferential adjustment, simplifying the installation process, reducing the risk of installation failure or C-clip deformation due to opening direction deviation, and significantly improving the first-time success rate of installation.

[0051] The C-ring feeding guide rod 136 is responsible for fitting the C-ring and maintaining its overall posture, while the C-ring feeding guide plate 142 adds a circumferential positioning function on this basis. The two work together to ensure that the C-ring is simultaneously subject to radial constraint (guide rod) and circumferential constraint (guide plate) during the conveying process, realizing complete posture control of the C-ring in three-dimensional space and ensuring that the C-ring enters the next process in the only correct posture.

[0052] The C-ring feeding guide plate 142 is a fixed structure. After being connected to the C-ring feeding guide rod 136, it works together with the guide rod without the need for an additional drive device or control system. During the vibratory conveying process, the C-ring automatically fits against the guide plate to complete the opening direction adjustment by relying on the combined action of its own gravity and vibration force. The structure is simple, the operation is reliable, and it does not increase the complexity of the equipment or maintenance costs.

[0053] Furthermore, please refer to the following: Figure 7 and Figure 8 The C-ring pusher plate 139 includes a pusher base plate 1391, a first positioning protrusion 1392, and a second positioning protrusion 1393. The pusher base plate 1391 is slidably disposed in the C-ring pusher groove 137b. The pusher base plate 1391 has a C-ring positioning groove 139a for receiving the C-ring. The first positioning protrusion 1392 and the second positioning protrusion 1393 are both disposed in the C-ring positioning groove 139a. The first positioning protrusion 1392 and the second positioning protrusion 1393 are disposed opposite to each other. The first positioning protrusion 1392 is used to embed into the opening of the C-ring, and the second positioning protrusion 1393 abuts against the outer ring wall of the C-ring.

[0054] In this embodiment, after the C-ring falls from the C-ring receiving hole 137a into the C-ring positioning groove 139a, the first positioning protrusion 1392 is embedded into the opening of the C-ring, and the second positioning protrusion 1393 abuts against the outer ring wall of the C-ring. This two-point positioning ensures that the radial position and circumferential angle of the C-ring are precisely constrained when it slides within the pusher groove, preventing rotation or displacement due to the inertia of the pusher plate, thus ensuring that the C-ring is pushed to the desired position in the only correct posture.

[0055] After the C-ring pusher plate 139 pushes out the C-ring, the C-ring transfer installer 141 directly grabs the C-ring from the C-ring positioning groove 139a. Since the first positioning protrusion 1392 and the second positioning protrusion 1393 have locked the posture of the C-ring, the opening direction and spatial position of the C-ring are completely consistent each time the C-ring transfer installer 141 grabs it. It can be directly installed into the annular groove of the salad cover without additional adjustment, which significantly improves the accuracy and consistency of installation.

[0056] The first positioning protrusion 1392 is embedded in the opening of the C-ring to provide circumferential positioning; the second positioning protrusion 1393 abuts against the outer ring wall of the C-ring to provide radial support. The two are arranged opposite each other to ensure that the C-ring is subjected to uniform force during the pushing and gripping process, avoiding deformation of the C-ring opening or failure of elasticity caused by single-point force, protecting the structural integrity of the C-ring, and ensuring that it can still be reliably clamped between the salad cap and the female head seat after installation.

[0057] The C-ring feeding guide rod 136 and the C-ring feeding guide plate 142 have unified the opening direction of the C-rings. The first positioning protrusion 1392 and the second positioning protrusion 1393 of the C-ring pusher plate 139 further lock the C-ring's posture. These three components work together to form a posture control chain covering the entire process from vibration-based material distribution, guiding and conveying, pushing and separating to transfer and installation. This ensures that the C-ring's posture remains consistent and controllable throughout the entire process, providing a reliable guarantee for automated installation.

[0058] Furthermore, please refer to the following: Figure 7 and Figure 8 The C-buckle assembly device 1G also includes a C-buckle secondary positioning structure 10m. The C-buckle secondary positioning structure 10m includes a secondary positioning frame 143, a secondary positioning lifting motor 144, and a secondary positioning platform 145. The secondary positioning lifting motor 144 is connected to the secondary positioning frame 143, and the lifting end of the secondary positioning lifting motor 144 is connected to the secondary positioning platform 145. The secondary positioning platform 145 includes a positioning platform body 1451, a positioning post 1452, and a positioning guide plate 1453. The positioning platform body 1451 has a secondary positioning hole 145a. The positioning post 1452 and the positioning guide plate 1453 are both located in the secondary positioning hole 145a. The positioning post 1452 is fixed to the inner wall of the secondary positioning hole 145a by the positioning guide plate 1453. The positioning guide plate 1453 is used to guide the openings of each C-buckle to the same direction for a secondary time.

[0059] In this embodiment, after undergoing multiple stages such as vibration material distribution, guide rod conveying, and pusher plate pushing, the C-ring may experience slight posture deviations due to vibration, friction, or mechanical clearance. Before the C-ring transfer installer 141 grasps it, the secondary positioning structure 10m drives the secondary positioning platform 145 to descend via the secondary positioning lifting motor 144, so that the positioning post 1452 is embedded into the opening of the C-ring and the positioning guide plate 1453 guides the direction of the opening of the C-ring, performing final posture calibration on the C-ring, eliminating possible accumulated errors from previous stages, and ensuring that the C-ring enters the installation process with an absolutely accurate posture.

[0060] The positioning post 1452 is located within the secondary positioning hole 145a and is used to embed the opening of the C-ring, providing a circumferential positioning reference. The positioning guide plate 1453 is fixed to the inner wall of the secondary positioning hole 145a and is used to guide the opening of the C-ring to the same direction. With the cooperation of the two, even if there is a slight deviation in the opening direction of the C-ring after it is pushed by the pusher plate, it can be forcibly corrected during the descent of the secondary positioning table 145, ensuring that the opening orientation of each C-ring is completely consistent before installation.

[0061] After secondary positioning, the C-ring is in a uniquely determined position within the secondary positioning hole 145a. The C-ring transfer installer 141 directly grasps the C-ring from the secondary positioning hole 145a, with a completely uniform grasping position and angle, allowing for precise installation of the C-ring into the annular groove of the salad cap without additional adjustments. This significantly improves installation accuracy and reduces the risk of installation failure or C-ring deformation due to grasping deviations.

[0062] The C-button feeding guide plate 142 achieves initial opening direction unification, the first positioning protrusion 1392 and the second positioning protrusion 1393 of the C-button pusher plate 139 achieve secondary attitude locking, and the C-button secondary positioning structure 10m completes final attitude calibration. These three attitude control stages are progressive and mutually verifying, forming a redundant assurance mechanism. Even if an occasional deviation occurs in a previous stage, subsequent stages can still correct it, significantly improving the overall reliability and first-time success rate of the C-button assembly system.

[0063] Furthermore, please refer to the following: Figure 7 and Figure 8 The C-ring transfer installer 141 includes a C-ring transfer horizontal guide rail 1411, a C-ring transfer lifting motor 1412, and a C-ring adsorption cylinder 1413. The C-ring transfer horizontal guide rail 1411 is mounted on the C-ring mounting frame 140. The C-ring transfer lifting motor 1412 is slidably mounted on the C-ring transfer horizontal guide rail 1411. The lifting end of the C-ring transfer lifting motor 1412 is connected to the C-ring adsorption cylinder 1413. The adsorption end of the C-ring adsorption cylinder 1413 is used to transfer the C-ring from the C-ring pusher groove 137b to the secondary positioning hole 145a.

[0064] In this embodiment, the C-ring transfer horizontal guide rail 1411 spans above the C-ring pusher groove 137b and the secondary positioning hole 145a. The C-ring transfer lifting motor 1412 slides along the horizontal guide rail, driving the C-ring adsorption cylinder 1413 to move between the two workstations. The adsorption cylinder first picks up the C-ring from the C-ring pusher groove 137b, transfers it to the secondary positioning hole 145a for release, and after secondary positioning is completed, it passes through the secondary positioning hole 145a and is finally transferred to the salad cap ring groove for installation. This structure enables a single transfer device to complete the dual-workstation transfer task of "pusher position → secondary positioning → installation position", reducing the number of actuators and simplifying the equipment layout.

[0065] The C-ring is an open-type elastic part, small in size and delicate in structure. Mechanical clamping can easily cause deformation of the opening or scratches on the surface. The C-ring adsorption cylinder 1413 uses vacuum adsorption to pick up the material. It uses negative pressure to adsorb the C-ring onto the end face of the suction head. There is no mechanical squeezing during the picking and placing process, which fully preserves the elastic properties and surface quality of the C-ring, ensuring that it can still be reliably clamped between the salad cap and the female head seat after installation.

[0066] The C-ring transfer installer 141 is not only responsible for the final installation, but also undertakes the intermediate transfer task of moving the C-ring from the pusher groove to the secondary positioning hole 145a. After the C-ring is initially positioned in the pusher groove by the pusher plate, it is moved by the adsorption cylinder to the secondary positioning hole 145a for final posture calibration, and then installed onto the salad cover from the secondary positioning hole 145a. This closed-loop design, in which "material picking-calibration-installation" is completed by the same mechanism, reduces intermediate handover links and avoids the risk of posture deviation caused by multiple handovers.

[0067] The C-clamp transfer horizontal guide rail 1411 is responsible for horizontal station switching, while the C-clamp transfer lifting motor 1412 is responsible for vertical material loading and unloading. Both are driven independently and do not interfere with each other. Horizontal movement and vertical lifting can be performed in parallel or sequentially, with flexible and adjustable action rhythm, facilitating precise matching with the production rhythm of preceding and following processes and improving overall production efficiency.

[0068] In another embodiment, after the C-ring is calibrated by the secondary positioning hole 145a, the C-ring adsorption cylinder 1413 adsorbs and inserts the C-ring into the annular groove of the salad cap.

[0069] Furthermore, please refer to the following: Figure 7 and Figure 8 The C-clamp transfer installer 141 also includes a C-clamp transfer connecting plate 1414, a C-clamp transfer connecting pipe 1415, and a C-clamp transfer spring 1416. The lifting end of the C-clamp transfer lifting motor 1412 is connected to the C-clamp transfer connecting plate 1414. The C-clamp transfer connecting pipe 1415 is movably connected to the C-clamp transfer connecting plate 1414. The C-clamp transfer connecting pipe 1415 is also fixedly connected to the C-clamp adsorption cylinder 1413. The C-clamp transfer spring 1416 is sleeved on the outside of the C-clamp transfer connecting pipe 1415. The C-clamp transfer spring 1416 abuts against the C-clamp transfer connecting plate 1414 and the C-clamp adsorption cylinder 1413 respectively.

[0070] In this embodiment, when the C-button transfer lifting motor 1412 drives the C-button transfer connecting plate 1414 to descend, the C-button adsorption cylinder 1413 also descends, pressing the C-button into the salad cap annular groove. When the C-button contacts the bottom of the annular groove or encounters installation resistance, the C-button transfer spring 1416 is compressed, and the C-button transfer connecting tube 1415 slides upward relative to the C-button transfer connecting plate 1414, causing a buffer displacement between the adsorption cylinder and the connecting plate. This flexible structure converts the rigid downward pressure into the elastic force of the spring, preventing the C-button or salad cap from deforming, scratching, or even breaking due to overpressure, thus protecting the integrity of the parts.

[0071] There may be slight deviations in the depth of the salad cap annular groove, the thickness of the C-ring, and the positioning height of the female head seat in the transfer fixture 100. The compression of the C-ring transfer spring 1416 can be adaptively adjusted. When the C-ring is installed in place but the lifting motor has not yet reached the lower stop point, the spring absorbs excess stroke, ensuring that the C-ring is pressed into the bottom of the annular groove and subjected to uniform force, avoiding overpressure due to over-travel or incomplete installation due to under-travel. This adaptive compensation mechanism significantly improves installation consistency and yield.

[0072] The C-clamp transfer connecting pipe 1415 is movably connected to the C-clamp transfer connecting plate 1414, rather than being rigidly fixed. During installation, the spring's cushioning effect protects the adsorption cylinder from direct impact loads, reducing the wear rate of the cylinder's internal seals and guide structure. Simultaneously, the movable connection avoids the risk of cylinder piston rod bending or connecting component breakage due to excessive installation resistance, extending the service life of the adsorption cylinder and the entire transfer installation mechanism.

[0073] The C-ring has completed its final posture calibration in the secondary positioning hole 145a. After the C-ring adsorption cylinder 1413 picks it up, the opening direction and spatial position of the C-ring are precisely determined. The flexible pressing provided by the C-ring transfer spring 1416 only produces buffer displacement in the vertical direction and does not introduce horizontal shaking or rotation, thus not disrupting the calibrated posture of the C-ring. During the pressing of the C-ring into the salad cap annular groove, the opening direction is always aligned with the notch of the annular groove, ensuring the unity of installation accuracy and flexible protection.

[0074] Furthermore, please refer to the following: Figure 7 and Figure 8 The C-clamp transfer connecting plate 1414 has a steering through hole 141a, which is connected to the interior of the C-clamp transfer connecting tube 1415. The C-clamp secondary positioning structure 10m also includes a steering lifting motor 146 and a steering sleeve 147. The steering lifting motor 146 is connected to the secondary positioning frame 143. The telescopic end of the steering lifting motor 146 is connected to the steering sleeve 147. The inner tube of the steering sleeve 147 is embedded in the steering sleeve 147 through the steering through hole 141a to adjust the rotation direction of the C-clamp adsorption cylinder 1413.

[0075] In this embodiment, when the C-ring is pushed out of the feeding groove, although its opening direction is initially unified by the C-ring feeding guide plate 142, it may undergo slight deflection during the adsorption and transfer process due to airflow disturbance or mechanical vibration. The steering lifting motor 146 drives the steering sleeve 147 to descend, and the inner tube of the steering sleeve 147 is embedded into the C-ring transfer connecting pipe 1415 through the steering through hole 141a, driving the C-ring adsorption cylinder 1413 to rotate to a preset angle, so that the opening direction of the C-ring is precisely aligned with the positioning post 1452 and the positioning guide plate 1453 in the secondary positioning hole 145a. This active steering action ensures that when the C-ring is placed into the secondary positioning hole 145a, the opening can be smoothly embedded into the positioning post 1452, completing the final attitude calibration.

[0076] The steering lifting motor 146 operates during the transfer of the C-ring from the pusher groove to the secondary positioning hole 145a. The cylinder rotation is achieved through the internal engagement of the steering sleeve 147 and the C-ring transfer connecting pipe 1415. When the C-ring completes its secondary positioning and enters the installation stage, the steering lifting motor 146 drives the steering sleeve 147 to rise and disengage, and the C-ring transfer connecting pipe 1415 returns to its active connection with the C-ring transfer connecting plate 1414. The flexible buffering function of the C-ring transfer spring 1416 remains unaffected. Both operate in a time-sharing manner without interference, ensuring both the accuracy of steering positioning and the preservation of flexible protection during installation.

[0077] The inner tube of the steering sleeve 147 is embedded inside the C-clip transfer connecting tube 1415 through the steering through hole 141a. The steering action is completed inside the connecting tube, without occupying external space. This embedded design highly integrates the steering mechanism with the C-clip transfer installer 141, eliminating the need for additional steering stations or expanding the equipment layout. It maintains the structural compactness of the C-clip assembly station and facilitates its arrangement in the limited space next to the circulating guide rail 1A. The steering sleeve 147 has an independent drive source, allowing for the extension, retraction, and rotation adjustment of its inner tube.

[0078] If the opening of the C-ring is angularly misaligned with the positioning post 1452 in the secondary positioning hole 145a after it is removed from the pusher groove, the C-ring may fail to embed properly into the positioning post 1452, resulting in secondary positioning failure. The steering lifting motor 146 and steering sleeve 147 perform directional correction before the C-ring is inserted into the secondary positioning hole 145a, ensuring precise alignment between the C-ring opening and the positioning post 1452. This allows the C-ring to fall smoothly into the secondary positioning hole 145a and complete attitude locking, significantly improving the success rate of secondary positioning and the overall reliability of the system.

[0079] In one embodiment, please refer to Figure 9The female head flipping device 1H includes a flipping frame 148, a female head lifting motor 149, a female head flipping motor 150, and a female head flipping gripper 151. The female head lifting motor 149 is connected to the flipping frame 148, the lifting end of the female head lifting motor 149 is connected to the female head flipping motor 150, and the flipping shaft of the female head flipping motor 150 is connected to the female head flipping gripper 151. The female head flipping gripper 151 is used to grip the female head seat.

[0080] In this embodiment, the female head flipping gripper 151 picks up the female head seat with the first end assembly completed from the transfer fixture 100. The female head lifting motor 149 drives the gripper to rise, causing the female head seat to disengage from the fixture. The female head flipping motor 150 drives the gripper to rotate 180 degrees, flipping the second end of the female head seat upwards. Then, the female head lifting motor 149 drives it to descend and return it to the transfer fixture 100. This action changes the originally downward-facing second end to an upward-facing one, providing the correct workpiece posture for the subsequent installation of second-end parts such as the outer sealing ring, movable valve, second spring, fixed valve, and key ring, achieving seamless connection between the two-end assembly processes.

[0081] The first end of the female connector has the salad cap locked in place by a C-clasp, and the internal components are in a sealed state. When gripping, the female connector flipping jaws 151 select the outer wall of the female connector or the locked salad cap as the gripping point to avoid direct contact with the internal components. During the flipping process, the jaws maintain a stable gripping force, and the female connector flipping motor 150 rotates at a uniform speed without impact or vibration, ensuring that the inner sealing ring, first spring, washer, PIN pin, etc., will not shift or loosen due to inertia or shaking during the flipping process, thus guaranteeing the integrity of the first end assembly.

[0082] The female head lifting motor 149 is responsible for the vertical picking and placing action, while the female head tilting motor 150 is responsible for the circumferential tilting action. The two are driven independently and do not interfere with each other. The lifting stroke precisely controls the relative position between the gripper and the transfer fixture 100, ensuring accurate alignment of the female head seat and the fixture during picking and placing. The tilting angle is precisely controlled by a 180-degree rotation, ensuring that the second end of the female head seat faces vertically upward after tilting, providing a unified positioning reference for subsequent processes.

[0083] After the female head seat is flipped over, it is placed back into the transfer fixture 100 with its second end facing upwards and its position fixed. Subsequent processes such as external seal assembly, movable valve assembly, second spring assembly, fixed valve assembly, key buckle assembly, and pressing assembly are all based on this unified workpiece posture and position benchmark, avoiding installation deviations caused by inconsistent workpiece postures and ensuring the assembly accuracy and consistency of all parts at the second end.

[0084] In one embodiment, please refer to Figure 10The outer sealing assembly device 1I includes an outer ring feeding structure 10n and an outer ring mounting structure 10o; the outer ring feeding structure 10n includes an outer ring feeding base 152, an outer ring feeding mixing tank 153, an outer ring pusher 154, and an outer ring feeder 155. The outer ring feeding mixing tank 153 is disposed on the outer ring feeding base 152 and is used for cutting and distributing the inner sealing ring; the outer ring feeder 155 includes an outer ring feeding platform 155. 1. An outer ring feeding lifting motor 1552 is connected to an outer ring feeding base 152. The lifting end of the outer ring feeding lifting motor 1552 is connected to an outer ring feeding platform 1551. The outer ring feeding platform 1551 has an outer ring feeding channel, which is connected to the discharge port of the outer ring feeding mixing tank 153. The outlet of the outer ring feeding channel faces the transmission clamp 100. The outer ring pusher 154 includes an outer ring pusher guide rail 15. 41. An outer ring pusher slider 1542 and an outer ring pusher plate 1543; an outer ring pusher guide rail 1541 is connected to an outer ring feeding base 152; the outer ring pusher slider 1542 is slidably mounted on the outer ring pusher guide rail 1541; the outer ring pusher plate 1543 is connected to the outer ring pusher slider 1542; the outer ring pusher plate 1543 is slidably mounted in the outer ring feeding channel to push out the inner sealing ring; the outer ring mounting structure 10o includes an outer ring mounting bracket 156. The outer ring is equipped with a horizontal guide rail 157, an outer ring is equipped with a lifting motor 158, and an outer ring is equipped with a clamp 159. The outer ring is equipped with a horizontal guide rail 157 on an outer ring mounting frame 156. The outer ring is equipped with a lifting motor 158 slidably on the outer ring is equipped with a horizontal guide rail 157. The lifting end of the outer ring is connected to the outer ring is equipped with a clamp 159. The outer ring is equipped with a clamp 159 for clamping the outer sealing ring and installing it in the annular groove at the second end of the female head seat.

[0085] In this embodiment, the outer ring feeding mixing tank 153 cuts and distributes the bulk outer sealing rings, allowing them to enter the outer ring feeding channel in an orderly manner; the outer ring pusher 154 pushes individual sealing rings along the channel to the outlet; the outer ring mounting gripper 159 grips the sealing rings from the outlet of the feeding channel and, with the cooperation of the horizontal guide rail and the lifting motor, moves them to the top of the second end of the female head seat, precisely installing the sealing rings in the annular groove of the second end. The entire device seamlessly connects the four stages of "distribution-feeding-gripping-installation", completely replacing manual operation and realizing unmanned operation of the second end sealing process.

[0086] The outer ring mounting jaw 159 clamps the outer sealing ring externally, facilitating its insertion into the second end of the female head seat. This installation method avoids the possibility of twisting or flipping the sealing ring that might occur if it is pressed directly into the end face, ensuring that the sealing ring fits evenly and without twisting within the annular groove. This provides a reliable guarantee for the subsequent installation of the moving valve and the overall sealing performance.

[0087] After the female head seat is flipped by the flipping device, the second end faces upward and is fixed in position. The external sealing assembly device 1I is directly installed based on this unified workpiece posture. After the external sealing ring is embedded in the second end annular groove, it provides a sealing reference and axial positioning reference for the subsequent installation of parts such as the moving valve, the second spring, and the fixed valve. It is the key starting process of the second end assembly sequence.

[0088] The outer ring feeding lifting motor 1552 can adjust the height of the outer ring feeding platform 1551, ensuring precise alignment between the feeding channel outlet and the material-taking position of the outer ring mounting jaws 159. The outer ring mounting horizontal guide rail 157 allows the jaws to move flexibly between the feeding position and the mounting position. This multi-axis adjustable design not only compensates for assembly errors but also allows the equipment to adapt to different sizes of sealing rings and installation positions by adjusting the feeding height and conveying stroke when switching between different specifications of female head seats, thus enhancing the equipment's flexible production capabilities.

[0089] In one embodiment, please refer to Figure 11 The movable valve assembly device 1J includes a movable valve feeding structure 10p and a movable valve mounting structure 10q. The movable valve feeding structure 10p includes a movable valve vibrating feeder 160 and a movable valve transfer table 161. The movable valve vibrating feeder 160 is used for vibrating and distributing the movable valve. The discharge port of the movable valve vibrating feeder 160 faces the movable valve transfer table 161, which is used to receive the movable valve. The movable valve mounting structure 10q includes a movable valve mounting bracket 162, a movable valve mounting horizontal guide rail 163, a movable valve mounting lifting motor 164, and a movable valve mounting gripper 165. The movable valve mounting horizontal guide rail 163 is set on the movable valve mounting bracket 162. The movable valve mounting lifting motor 164 is slidably set on the movable valve mounting horizontal guide rail 163. The lifting end of the movable valve mounting lifting motor 164 is connected to the movable valve mounting gripper 165. The movable valve mounting gripper 165 is used to clamp the movable valve and pass through the inner sealing ring.

[0090] In this embodiment, the vibratory feeder 160 vibrates and distributes the bulk movable valves to the movable valve turntable 161. After the movable valve mounting claw 165 picks up the movable valve from the turntable, it is moved above the female head seat with the cooperation of the horizontal guide rail and the lifting motor, and the movable valve is axially inserted into the female head seat. The valve stem of the movable valve passes through the inner hole of the inner sealing ring at the first end, providing a reference for the subsequent installation of the spring and the fixed valve.

[0091] The movable valve mounting jaws 165 employ an internal clamping method to hold the movable valve. The jaws are opened from the inside to clamp the valve body, ensuring the movable valve remains coaxial with the inner bore of the female head seat during transfer and insertion. This internal clamping method avoids interference between the jaws and the inner wall of the female head seat or the already installed inner sealing ring, ensuring the valve stem smoothly passes through the inner bore of the inner sealing ring without scratching or rolling up the sealing ring lip, thus protecting the integrity and sealing performance of the sealing ring.

[0092] The precise control of the stroke of the lifting motor 164 on the movable valve installation controls the insertion depth of the movable valve, ensuring that the axial position of the movable valve within each female head seat is completely consistent. This positional accuracy directly affects the compression of the subsequent second spring and the installation position of the fixed valve. The uniform position of the movable valve provides an accurate benchmark for subsequent spring assembly and fixed valve assembly, ensuring the assembly consistency of the internal structure of each female head seat.

[0093] After the movable valve is inserted, its body is located inside the female head seat, and the valve stem passes through the inner sealing ring. At this point, a sealing core structure consisting of the inner sealing ring, the movable valve, and the outer sealing ring has been formed inside the female head seat. The valve body of the movable valve provides internal support and guidance for the subsequent second spring. The second spring will be sleeved on the valve stem of the movable valve, with one end abutting against the valve body of the movable valve, and the other end being pressed by the fixed valve. The accurate installation of the movable valve is a prerequisite for the correct assembly of the subsequent spring and the fixed valve.

[0094] In one embodiment, please refer to Figure 12 The second spring assembly device 1K includes a second spring feeding structure 10r and a second spring mounting structure 10s. The second spring feeding structure 10r includes a second spring feeding base 166 and a second spring vibrating feeder 167, which is mounted on the second spring feeding base 166 and is used for vibrating and distributing the second springs. The second spring mounting structure 10s includes a second spring mounting bracket 168, a second spring mounting lifting motor 169, a second spring mounting pushing motor 170, a third pushing plate 171, and a fourth pushing plate 172. The second spring mounting lifting motor 169 is mounted on the second spring mounting bracket 168. The lifting end of the lifting motor 169 is connected to the fourth pusher plate 172. The third pusher plate 171 and the fourth pusher plate 172 are arranged parallel to each other. The third pusher plate 171 has a third discharge hole 171a, which is used to accommodate the second spring output by the second spring vibrating feeder 167. The fourth pusher plate 172 has a fourth discharge hole 172a, which is aligned with the second end of the female head seat. The second spring mounting pusher motor 170 is connected to the fourth pusher plate 172. The telescopic end of the second spring mounting pusher motor 170 is connected to the third pusher plate 171 so that the second spring in the third discharge hole 171a is passed through the fourth discharge hole 172a into the movable valve.

[0095] In this embodiment, the second spring vibratory feeder 167 vibrates and distributes the bulk springs, ensuring their orderly output into the third discharge hole 171a of the third pusher plate 171. The second spring mounting pusher motor 170 drives the third pusher plate 171 to translate, moving the springs to the fourth discharge hole 172a of the fourth pusher plate 172. Then, the second spring mounting lifting motor 169 drives the fourth pusher plate 172 to descend, inserting the springs along the valve stem of the movable valve into the female head seat. This entire process follows the movable valve assembly process, achieving automatic spring feeding and installation. The springs are sleeved on the valve stem of the movable valve, with one end abutting against the valve body, providing elastic support for the subsequent clamping of the fixed valve.

[0096] The third pusher plate 171 and the fourth pusher plate 172 are arranged parallel to each other. The spring is always constrained within the discharge hole during the transfer process, preventing it from flipping or falling off. The fourth discharge hole 172a is aligned with the second end of the female head seat, ensuring that the spring is coaxial with the movable valve stem when it falls, and that there is no deviation or jamming during insertion. This provides a reliable positional reference for the subsequent contact and engagement between the fixed valve and the spring in the fixed valve assembly device 1L, ensuring the accurate positioning of the spring inside the female head seat.

[0097] The second spring-mounted pusher motor 170 is responsible for horizontally moving the spring, while the second spring-mounted lifting motor 169 is responsible for vertically threading the spring. These two actions are driven by independent motors and do not interfere with each other. This design simplifies the control logic, facilitates debugging and maintenance, reduces the risk of mechanical interference caused by combined actions, and improves the stability of equipment operation.

[0098] The second spring is fitted onto the valve stem of the movable valve. Installation is performed vertically from above the second end of the female head seat, with the spring descending smoothly along the valve stem. The stroke of the second spring installation lifting motor 169 can be precisely controlled, ensuring the spring stops immediately after insertion, preventing compression or displacement of the installed movable valve, inner sealing ring, or outer sealing ring, thus guaranteeing the assembly results of the preceding process. After installation, one end of the spring abuts against the valve body of the movable valve, while the other end protrudes from the second end of the female head seat, providing a clear force-bearing position for pressing and compressing the fixed valve.

[0099] In one embodiment, please refer to the following: Figures 13 to 15 The fixed valve assembly device 1L includes a fixed valve feeding structure 10t, a fixed valve transfer structure 10u, a fixed sealing ring feeding structure 10v, and a fixed sealing ring transfer structure 10w. Please refer to [link / reference]. Figure 13The fixed valve feeding structure 10t includes a fixed valve vibratory feeder 173 and a fixed valve transfer table 174. The fixed valve vibratory feeder 173 is used for vibrating and distributing the fixed valve. The discharge port of the fixed valve vibratory feeder 173 faces the fixed valve transfer table 174, which is used to receive the fixed valve. The fixed valve transfer structure 10u includes a fixed valve transfer frame 175, a fixed valve transfer horizontal guide rail 176, a fixed valve transfer lifting motor 177, and a fixed valve transfer gripper 178. The fixed valve transfer positioning gripper 179, the fixed valve transfer horizontal guide rail 176, and the fixed valve transfer positioning gripper 179 are all mounted on the fixed valve transfer frame 175. The fixed valve transfer lifting motor 177 is slidably mounted on the fixed valve transfer horizontal guide rail 176. The lifting end of the fixed valve transfer lifting motor 177 is connected to the fixed valve transfer gripper 178. The fixed valve transfer gripper 178 is used to transfer the fixed valve from the fixed valve transfer table 174 to the fixed valve transfer positioning gripper 179 for fixing. Please see Figure 14 The fixed sealing ring feeding structure 10V includes a fixed sealing ring feeding base 180, a fixed sealing ring feeding mixing tank 181, a fixed sealing ring pusher 182, and a fixed sealing ring feeder 183. The fixed sealing ring feeding mixing tank 181 is disposed on the fixed sealing ring feeding base 180 and is used for cutting and distributing the inner sealing rings. The fixed sealing ring feeder 183 includes a fixed sealing ring feeding platform 1831 and a fixed sealing ring feeding lifting motor 1832. The fixed sealing ring feeding lifting motor 1832 is connected to the fixed sealing ring feeding base 180, and the lifting end of the fixed sealing ring feeding lifting motor 1832 is connected to the fixed sealing ring feeding platform 1831. The sealing ring feeding platform 1831 has a fixed sealing ring feeding channel, which is connected to the discharge port of the fixed sealing ring feeding mixing tank 181; the fixed sealing ring pusher 182 includes a fixed sealing ring pusher guide rail 1821, a fixed sealing ring pusher slider 1822, and a fixed sealing ring pusher plate 1823. The fixed sealing ring pusher guide rail 1821 is connected to the fixed sealing ring feeding base 180. The fixed sealing ring pusher slider 1822 is slidably disposed on the fixed sealing ring pusher guide rail 1821. The fixed sealing ring pusher plate 1823 is connected to the fixed sealing ring pusher slider 1822. The fixed sealing ring pusher plate 1823 is slidably disposed in the fixed sealing ring feeding channel to push out the fixed sealing ring. Please see Figure 15The fixed sealing ring transfer structure 10w includes a fixed sealing ring transfer guide rail 184, a first fixed sealing ring transfer lifting motor 185, a second fixed sealing ring transfer lifting motor 186, a fixed sealing ring gripper 187, and a fixed sealing ring lifting plate 188. The first fixed sealing ring transfer lifting motor 185 is slidably mounted on the fixed sealing ring transfer guide rail 184. The lifting end of the first fixed sealing ring transfer lifting motor 185 is connected to the second fixed sealing ring transfer lifting motor 186 and the fixed sealing ring gripper 187, respectively. The fixed sealing ring gripper 187 is used to grip the fixed sealing ring output from the discharge port of the fixed sealing ring feeding mixing tank 181. The fixed sealing ring lifting plate 188 has a ring removal hole 188a. Specifically, the diameter of the ring removal hole 188a is smaller than the diameter of the fixed sealing ring. The gripping end of the fixed sealing ring clamp 187 is located inside the ring removal hole 188a. The fixed sealing ring lifting plate 188 is used to receive the fixed sealing ring. The lifting end of the second fixed sealing ring transfer lifting motor 186 is connected to the fixed sealing ring lifting plate 188 so as to lift the fixed sealing ring from the gripping end of the fixed sealing ring clamp 187 and install it on the fixed valve.

[0100] In this embodiment, the fixed valve feeding structure 10t and the fixed sealing ring feeding structure 10v operate independently. The fixed valve vibrating feeder 173 distributes the fixed valve to the fixed valve turntable 174, while the fixed sealing ring feeding mixing tank 181 cuts off the fixed sealing ring and distributes it to the feeding channel. The fixed valve transfer structure 10u transfers the fixed valve from the turntable to the positioning gripper for fixation, and the fixed sealing ring transfer structure 10w picks up the sealing ring from the feeding channel and transfers it to the location of the fixed valve for installation. The two structures feed materials in parallel and assemble collaboratively, allowing the fixed valve and fixed sealing ring to be assembled in the same workstation, reducing the number of processes and shortening the production cycle.

[0101] After the fixed valve transfer gripper 178 picks up the fixed valve from the fixed valve transfer table 174, it is transferred to the fixed valve transfer positioning gripper 179 for fixation with the cooperation of the horizontal guide rail and the lifting motor. The positioning gripper performs secondary clamping and positioning of the fixed valve, eliminating any posture deviations that may occur during the transfer process and ensuring that the fixed valve is in the only correct posture to await the subsequent pressing action. This provides a reliable posture reference for the precise pressing of the fixed valve into the second end of the female head seat and the compression of the second spring.

[0102] After the sealing ring clamp 187 picks up the sealing ring from the feeding channel, it is moved to below the fixed valve under the drive of the first sealing ring transfer lifting motor 185. The sealing ring lifting plate 188 receives the sealing ring, and the second sealing ring transfer lifting motor 186 drives the lifting plate to rise, smoothly lifting the sealing ring from the clamping end of the clamp through the ring removal hole 188a, and then fitting it onto the fixed valve. This ring removal installation method avoids the sealing ring from twisting or flipping during the fitting process, ensuring that the sealing ring fits evenly against the outer wall of the fixed valve, thus guaranteeing a seal between the fixed valve and the inner wall after it is pressed into the female head seat.

[0103] After the fixed valve is fitted with a fixed sealing ring, a subsequent pressing mechanism presses the fixed valve into the second end of the female head seat. During the pressing of the fixed valve, the second spring is compressed, creating an elastic preload between the moving valve body and the fixed valve. The fixed sealing ring forms a seal between the fixed valve and the inner wall of the female head seat, preventing fluid leakage from the outer periphery of the fixed valve. This structure integrates the moving valve, the second spring, the fixed valve, and the fixed sealing ring into an internal component with elastic reset and sealing functions, representing a key step in the internal valve core structure of the female head seat.

[0104] After the fixed valve is pressed in, the movable valve can move axially under the elastic force of the second spring, and the fixed sealing ring ensures reliable sealing. At this time, the internal valve core structure of the second end of the female head seat is basically completed, and the end face of the fixed valve is exposed on the second end face, providing a clear docking position and force support for the subsequent key buckle fastening installation. The installation depth of the fixed valve and the compression of the sealing ring directly affect the key buckle fastening effect and overall sealing performance. Precise assembly in this process is a prerequisite for the smooth progress of subsequent assembly.

[0105] Furthermore, please refer to the following: Figure 14 and Figure 15 The fixed valve assembly device 1L also includes a fixed sealing ring transfer structure 10x. The fixed sealing ring transfer structure 10x includes a fixed sealing ring transfer guide rail 189, a first fixed sealing ring transfer lifting motor 190, a second fixed sealing ring transfer lifting motor 191, a fixed sealing ring transfer connecting plate 192, a fixed sealing ring transfer platform 193, and a fixed sealing ring transfer picking rod 194. The fixed sealing ring transfer platform 193 is used to hold the fixed sealing rings output from the discharge port of the fixed sealing ring feeding mixing tank 181. The first fixed... The sealing ring transfer lifting motor 190 is slidably mounted on the fixed sealing ring transfer guide rail 189. The lifting end of the first fixed sealing ring transfer lifting motor 190 is connected to the fixed sealing ring transfer connecting plate 192. The second fixed sealing ring transfer lifting motor 191 is mounted on the fixed sealing ring transfer connecting plate 192. The lifting end of the second fixed sealing ring transfer lifting motor 191 is connected to the fixed sealing ring transfer ring taking rod 194. The fixed sealing ring transfer ring taking rod 194 is used to clamp the fixed sealing ring onto the fixed sealing ring clamp 187.

[0106] In this embodiment, after the fixed sealing ring is cut and distributed by the feeding mixing tank 181, it is pushed to the outlet of the feeding channel by the fixed sealing ring pusher 182. The fixed sealing ring transfer rod 194 clamps the fixed sealing ring from the outlet of the feeding channel. With the cooperation of the first fixed sealing ring transfer lifting motor 190 and the second fixed sealing ring transfer lifting motor 191, the sealing ring is accurately transferred to the clamping end of the fixed sealing ring gripper 187. This transfer link avoids the positional deviation that may occur if the fixed sealing ring transfer structure 10w directly picks up the material from the feeding channel, ensuring that the sealing ring is handed over to the transfer gripper in an accurate posture, providing a reliable premise for subsequent ring retraction installation.

[0107] The ring-retrieving rod 194 in the fixed sealing ring adopts an internal clamping method to retrieve the ring, opening and clamping it from the inner hole of the sealing ring rather than squeezing it from the outside. This ring-retrieving method avoids deformation of the outer diameter or surface scratches of the sealing ring that may be caused by external clamping, and fully preserves the elastic properties and dimensional accuracy of the sealing ring, ensuring that it can still fit evenly and reliably seal when it is subsequently fitted onto the outer wall of the fixed valve.

[0108] The first fixed sealing ring transfer lifting motor 190 slides along the fixed sealing ring transfer guide rail 189, responsible for horizontal material handling; the second fixed sealing ring transfer lifting motor 191 is mounted on the transfer connecting plate, responsible for vertical material handling. The two motors work together to allow for precise installation and adjustment of the fixed sealing ring transfer rod 194, facilitating accurate docking in a compact equipment layout. Simultaneously, the picking and placing height and conveying stroke can be adjusted according to different sealing ring specifications.

[0109] The fixed sealing ring feeding mixing tank 181 and the pusher are responsible for feeding materials. The fixed sealing ring transfer structure 10x is responsible for picking up materials from the feeding channel and transferring them to the transfer gripper. The fixed sealing ring transfer structure 10w is responsible for transferring the sealing ring above the fixed valve and completing the uncoupling installation. The three work together to form a complete automated link from bulk material supply to the sealing ring being fitted onto the fixed valve. Each link has a clear division of labor and close connection, which improves the overall efficiency and reliability of fixed sealing ring assembly.

[0110] Further, please refer to Figure 16 The fixed valve assembly device 1L also includes a transfer plate 195, which is adjacent to the circulation guide rail 1A. The transfer plate 195 has multiple transfer grooves 195a. The fixed valve transfer gripper 178 is used to transfer the structural components after the fixed sealing ring and fixed valve are assembled into the transfer grooves 195a.

[0111] In this embodiment, the fixed valve transfer gripper 178 transfers the structural component after the fixed sealing ring and fixed valve are assembled to the transfer groove 195a of the transfer plate 195 for temporary storage. The transfer plate 195 is located adjacent to the circulating guide rail 1A, serving as a buffer between the fixed valve assembly station and the subsequent key buckle assembly station, allowing the two stations to operate independently without waiting for each other. Even if there are differences in the cycle time of the preceding and following processes, the transfer plate 195 can balance the production rhythm by temporarily storing the assembled components, avoiding downtime caused by cycle time mismatch and improving the overall production line efficiency.

[0112] The transfer tray 195 has multiple transfer slots 195a, which can simultaneously store multiple assemblies of fixed valves and fixed sealing rings. The fixed valve assembly station continuously places assemblies into the transfer slots 195a, and the subsequent key ring assembly station retrieves them sequentially from the transfer slots 195a, forming a continuous feeding mode. This multi-slot design ensures that there are always usable assemblies available in the transfer tray 195, allowing subsequent processes to begin without waiting for the fixed valves to be assembled, thus shortening the overall production cycle.

[0113] When the fixed valve transfer gripper 178 places the assembly into the transfer groove 195a, the transfer groove 195a provides positioning constraints to the assembly, ensuring it maintains a uniform posture and position. When the grippers at the subsequent keychain assembly station pick up the assembly from the transfer groove 195a, the gripping position and angle are always completely consistent, allowing for keychain fastening without additional adjustments, thus improving the success rate and installation accuracy of subsequent processes.

[0114] The transfer tray 195 is located adjacent to the circulating guide rail 1A. After the fixed valve transfer gripper 178 picks up the assembly from the fixed valve transfer positioning gripper 179, it only needs to be transferred a short distance to be placed into the transfer slot 195a. Similarly, after the gripper at the subsequent key fob assembly station picks up the material from the transfer slot 195a, it only needs to be transferred a short distance to reach the female head seat mounting position on the circulating guide rail 1A. The compact layout shortens the material flow path, reduces the transfer time, and also reduces the risk of positional deviation that may occur during long-distance transfer.

[0115] In another embodiment, the central turntable 195 is a self-rotating indexing plate, specifically, the central turntable 195 is rotated by a motor.

[0116] Furthermore, please refer to Figure 17The keychain assembly device 1M includes a keychain feeding structure 20a and a keychain mounting structure 20b. The keychain feeding structure 20a includes a keychain vibratory feeder 201 and a keychain transfer table 202. The keychain vibratory feeder 201 is used for vibrating and distributing keychains, and its outlet faces the keychain transfer table 202, which is used to receive keychains. The keychain mounting structure 20b includes a keychain mounting bracket 203 and a keychain mounting horizontal guide. The keychain mounting system includes a rail 204, a keychain mounting lifting motor 205, and a keychain mounting mechanical claw 206. The keychain mounting horizontal guide rail 204 is connected to the keychain mounting bracket 203. The keychain mounting lifting motor 205 is slidably mounted on the keychain mounting horizontal guide rail 204. The lifting end of the keychain mounting lifting motor 205 is connected to the keychain mounting mechanical claw 206. The keychain mounting mechanical claw 206 is used to transfer the keychain on the keychain transfer platform 202 and fasten it to the fixed valve in the transfer groove 195a.

[0117] In this embodiment, the keychain vibratory feeder 201 vibrates and distributes bulk keychains to the keychain transfer table 202. The keychain mounting mechanical claw 206 picks up the keychains from the transfer table and, with the cooperation of the horizontal guide rail and the lifting motor, moves them above the transfer slot 195a, where they are fastened onto the fixed valve. After the keychains are fastened, their two ends engage with the corresponding slots of the fixed valve, locking the fixed valve at the second end of the female head seat. This prevents the fixed valve from popping out under the force of the second spring, completing the external encapsulation of the second end of the female head seat and serving as the final step in the second end assembly sequence.

[0118] The fixed valve tends to pop outward under the elastic force of the second spring. After the key buckle is fastened to the fixed valve, it is mechanically locked axially. At this time, the movable valve, the second spring, the fixed valve, the fixed sealing ring, and the key buckle form a complete elastic pre-tightening assembly: the second spring provides elastic force between the movable valve body and the fixed valve, the key buckle ensures the stability of the fixed valve position, and the movable valve can move axially under the action of the spring force, providing a structural basis for the fluid on / off function when the female and male connectors are mated.

[0119] The key fob mounting manipulator 206 picks up the fixed valve assembly from the transfer slot 195a, rather than directly operating from the female head seat on the circulation guide 1A. The transfer slot 195a is adjacent to the circulation guide 1A; after the key fob mounting manipulator 206 picks up the assembly from the transfer slot 195a, it only needs to move it a short distance to complete the key fob's fastening installation. This proximity-based material picking method shortens the transport path and reduces the action time. At the same time, the positioning constraint of the transfer slot 195a on the assembly ensures consistent gripping posture each time, improving the fastening success rate.

[0120] After the key buckle is engaged, the fixed valve is locked, and the movable valve can move axially under the action of the second spring. At this point, the assembly of the second end of the female head seat is basically complete, and the end face of the key buckle provides a clear pressing target for the subsequent pressing assembly device 1N. The pressing assembly device 1N will apply pressure to the key buckle, causing the movable valve to compress the second spring, completing the functional test or pre-pressurization action of the valve core inside the female head seat. The accurate engagement of the key buckle is a prerequisite for the smooth progress of the pressing assembly.

[0121] Furthermore, please refer to Figure 18 The pressing assembly device 1N includes a pressing and picking structure 20c and a pressing and mounting structure 20d. The pressing and picking structure 20c includes a pressing frame 207, a pressing and picking horizontal guide rail 208, a pressing and picking lifting motor 209, and a pressing and picking mechanical claw 210. The pressing and picking horizontal guide rail 208 is mounted on the pressing frame 207. The pressing and picking lifting motor 209 is slidably mounted on the pressing and picking horizontal guide rail 208. The lifting end of the pressing and picking lifting motor 209 is connected to the pressing and picking mechanical claw 210, which is used to grab the assembly in the transfer trough 195a. The pressing and mounting structure 20d... The structure 20d includes a pressing and mounting lifting motor 211, a pressing and mounting rod 212, and a pressing and mounting platform 213. Both the pressing and mounting lifting motor 211 and the pressing and mounting platform 213 are mounted on the pressing frame 207. The pressing and mounting platform 213 has a pressing through hole 213a, which is opposite to the second end of the female head seat. The pressing through hole 213a is used to receive the assembly taken out by the pressing and picking mechanical claw 210 from the transfer groove 195a. The lifting end of the pressing and mounting lifting motor 211 is connected to the pressing and mounting rod 212, which is used to press the assembly into the second spring.

[0122] In this embodiment, the pressing and picking mechanical claw 210 picks up the assembled component with the key buckle already engaged from the transfer groove 195a, and moves it into the pressing through hole 213a of the pressing mounting platform 213 with the cooperation of the horizontal guide rail and the lifting motor. The pressing mounting lifting motor 211 drives the pressing mounting rod 212 to descend, pressing the assembly axially into the second end of the female head seat, causing the fixed valve to compress the second spring and be fully embedded in the inner cavity of the female head seat. This action integrates the movable valve, the second spring, the fixed valve, the fixed sealing ring, and the key buckle into a complete elastic valve core assembly, marking the completion of the assembly of the internal structure of the female head seat.

[0123] The pressing through hole 213a of the pressing mounting platform 213 is positioned opposite to the second end of the female head seat. The assembly is radially constrained within the pressing through hole 213a, ensuring that it remains coaxial with the inner hole of the female head seat when pushed by the pressing mounting rod 212. This guiding design prevents the assembly from skewing during the pressing process, preventing damage or folding of the fixed sealing ring due to skewing, ensuring that the sealing ring is evenly compressed between the fixed valve and the inner wall of the female head seat, and guaranteeing sealing reliability.

[0124] The precise control of the pressing and mounting motor 211's stroke controls the descent depth of the pressing and mounting rod 212, ensuring that the fixed valve within each female head seat is pressed into the same position. This depth control directly determines the compression of the second spring, which in turn affects the elastic restoring force of the movable valve and the opening stroke of the valve core. Uniform compression ensures consistent performance parameters of the valve core within each female head seat, providing a reliable guarantee for the fluid flow control function when the female head seat is connected to the male head.

[0125] The pressing assembly device 1N is the final step in the assembly sequence of the second end of the female connector. Prior to this, the outer sealing ring, movable valve, second spring, fixed valve, fixed sealing ring, and key buckle have been installed or assembled sequentially. After the pressing assembly device 1N presses the assembly into the female connector, all parts at the second end are in place, and the entire assembly process of the female connector is complete. This step provides a complete workpiece state for subsequent finished product cutting or functional testing of the female connector.

[0126] In the above embodiments, each guide rail has a corresponding drive cylinder to move the components located thereon.
