Description

Technical Field

[0001] This invention relates to the field of needleless connector assembly technology, and more specifically, to an assembly system and assembly method. Background Technology

[0002] Currently, needleless connectors are widely used in actual medical procedures. The assembly of a needleless connector requires the automatic assembly of the main valve body, rubber stopper, outer shell, and protective cap to form a complete needleless connector. Existing assembly processes fall into two categories: one involves manual assembly combined with semi-automatic tooling; the other uses ultrasonic welding technology to weld the outer shell and main valve body together.

[0003] However, manual assembly suffers from low efficiency, and manual operation can also lead to inconsistent assembly accuracy of the pinless connectors. Therefore, to ensure the assembly accuracy of the pinless connectors, an ultrasonic welding process is required. However, deploying ultrasonic welding equipment will significantly increase the complexity and cost of the assembly system. Summary of the Invention

[0004] The main objective of this invention is to provide an assembly system and assembly method to solve the technical problem of high assembly cost of needleless connectors in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, an assembly system is provided, comprising: a conveying assembly including a conveying section and a carrier, the conveying section being movably disposed and driving the carrier to move; a valve body feeding mechanism and a valve body lubrication mechanism, both disposed on the side of the conveying assembly, the valve body lubrication mechanism being located downstream of the valve body feeding mechanism, the valve body feeding mechanism being used to feed a main valve body onto the carrier, and the valve body lubrication mechanism being used to lubricate the main valve body; a valve core feeding mechanism and a valve core lubrication mechanism, both disposed on the side of the conveying assembly, the valve... The valve core feeding mechanism is located downstream of the valve body lubrication mechanism to feed the valve core onto the main valve body. The valve core lubrication mechanism is also located downstream of the valve core feeding mechanism to lubricate the valve core. The outer shell feeding mechanism, pressing mechanism, and valve core cutting mechanism are all located on the side of the conveying assembly. The outer shell feeding mechanism, located downstream of the valve core lubrication mechanism, feeds the outer shell onto the valve core. The pressing mechanism, located downstream of the outer shell feeding mechanism, presses the outer shell into place. The valve core cutting mechanism, located downstream of the pressing mechanism, cuts the valve core. This assembly system enables automatic assembly of the main valve body, valve core, and outer shell, improving the automation level of assembly, avoiding assembly quality instability that may result from manual operation, and reducing assembly costs.

[0006] Furthermore, the press-fitting mechanism includes: a force-applying component, movably disposed to approach or move away from the housing; and a limiting component, movably disposed and spaced apart from the force-applying component. The limiting component has a limiting groove that is adapted to at least a portion of the housing, and has a limiting position where the housing passes through the limiting groove and a clearance position spaced apart from the housing. When the limiting component is in the limiting position, the force-applying component applies a press-fitting force to the housing to press the housing onto the valve core. This avoids damage to the housing and / or valve core during the force-applying process, ensuring that the press-fitting of the housing, valve core, and main valve body is completed smoothly without damage to the housing and valve core.

[0007] Further, the force-applying assembly includes: a first force-applying member, which moves along a preset direction and abuts against the top of the housing. Alternatively, the force-applying assembly includes: a first force-applying member and a second force-applying member, wherein the first force-applying member moves along a preset direction and abuts against the top of the housing; the second force-applying member is rotatably disposed on the side of the first force-applying member near the housing, and is clamped onto the outer wall of the housing; wherein, when the first force-applying member moves along the preset direction, the second force-applying member is rotatably disposed so that the housing is pressed down onto the valve core during rotation. With this structural arrangement, the housing can be pressed down while being driven to rotate, thus smoothly pressing the housing onto the valve core.

[0008] Furthermore, the limiting component includes: a limiting plate with a limiting groove, the limiting plate being located on the side of the force-applying component near the outer shell; a mounting plate movably disposed along a preset direction, the mounting plate being connected to the limiting plate; wherein, the limiting component further includes a buffer member disposed between the mounting plate and the limiting plate, the mounting plate being connected to the limiting plate via the buffer member; and / or, the mounting plate is provided with a clearance hole, the force-applying component further includes a force-applying body, the force-applying body being movably disposed through the clearance hole along a preset direction, a first force-applying member being fixedly disposed on the force-applying body and located on the side of the mounting plate near the limiting plate, and a second force-applying member being rotatably disposed on the force-applying body and located on the side of the mounting plate near the limiting plate. Thus, by providing a buffer member between the mounting plate and the limiting plate, the limiting member can be easily buffered by the buffer member. By installing both the first and second force-applying components on the force-applying body, it is possible to synchronously drive the first and second force-applying components downward when the force-applying body moves. This also allows the second force-applying component to rotate during the pressing motion, thereby ensuring the smooth and synchronous execution of the pressing and rotating motions and improving the success of the pressing process.

[0009] Furthermore, the pressing mechanism also includes a pushing assembly disposed on the side of the conveying section away from the carrier component. The pushing portion of the pushing assembly is used to apply a pushing force to the conveying section. When the force-applying assembly applies a pressing force to the housing, the pushing assembly applies a pushing force to the conveying section. And / or, at least a portion of the force-applying assembly is connected to at least a portion of the limiting assembly so that when the limiting assembly moves to the limiting position, it drives the force-applying assembly to move synchronously towards the housing. By providing the pushing assembly, deformation of the conveying section during the pressing process can be avoided, improving the structural stability of the conveying section. By connecting at least a portion of the force-applying assembly to at least a portion of the limiting assembly, it is possible to make the limiting assembly and the force-applying assembly move synchronously under certain conditions, improving the compactness of the structural layout and minimizing the required drive structure.

[0010] Furthermore, the valve body lubrication mechanism and / or valve core lubrication mechanism include: a grease-applying structure and a pusher structure. The grease-applying structure is movably configured to move to a grease-taking position that contacts the solid grease and a grease-applying position that contacts the main valve body and / or valve core. The pusher structure moves in a direction close to or away from the grease-applying structure, and is used to push the solid grease to move in a direction close to the grease-applying structure. This facilitates smooth grease-taking and grease-applying operations to lubricate the main valve body and / or valve core, thereby facilitating the smooth press-fitting of the main valve body and valve core, and the smooth press-fitting of the valve core and housing.

[0011] Furthermore, the solid grease has a columnar structure, and the grease coating structure includes a first grease coating element and a second grease coating element. The grease coating structure has an open state and a closed state. When the grease coating structure is in the open state, the first and second grease coating elements are respectively used to clamp onto both sides of the solid grease and contact it, or the first and second grease coating elements are respectively used to clamp onto both sides of the main valve body and / or valve core and contact it. The above structure is simple and facilitates the lubrication operation of the main valve body and / or valve core.

[0012] Furthermore, there are multiple solid greases, and the pushing structure synchronously pushes multiple solid greases to move. There are also multiple grease-applying structures, each corresponding to a specific solid grease. Each grease-applying structure is used to collect the corresponding solid grease. These multiple grease-applying structures are used to apply grease to multiple valve cores and / or main valve bodies. And / or, the valve body lubrication mechanism and / or valve core lubrication mechanism also include a storage structure. The storage structure has a protective channel adapted to the solid grease, through which the solid grease passes. One end of the solid grease extends out of the protective channel to be at least partially opposite to the pushing structure, and the other end extends out of the protective channel to cooperate with the grease-applying structure. By setting multiple grease-applying structures, it is convenient to synchronously apply grease to multiple valve cores and / or main valve bodies, improving the lubrication speed. The protective channel effectively protects the solid grease, preventing excessive exposure.

[0013] Furthermore, the valve body feeding mechanism includes a first valve body feeding mechanism and a second valve body feeding mechanism arranged at intervals. The first valve body feeding mechanism is used to feed the first valve body, and the second valve body feeding mechanism is used to feed the second valve body. The carrier component is provided with a first carrier groove and a second carrier groove. The first carrier groove is adapted to the first valve body. The first valve body is fed into the first carrier groove, and the second valve body is fed into the second carrier groove. In this way, it is convenient to simultaneously position and support the first and second valve bodies, increase the adaptability of the carrier component, and also facilitate the simultaneous assembly of the first and second valve bodies.

[0014] Furthermore, the first valve body is a straight valve body, and a limiting gripper is provided on the carrier. The limiting gripper is adapted to the shape of the straight valve body and is closable on the carrier. When the straight valve body is fed into or unloaded from the first carrier groove, the limiting gripper opens; when the straight valve body is installed in the first carrier groove, the limiting gripper closes. And / or, the second valve body is a Y-shaped valve body, and the shape of the second carrier groove is adapted to the bifurcation of the Y-shaped valve body. This facilitates improved positioning stability of the first valve body through the cooperation of the first carrier groove and the limiting gripper, ensuring stable positioning of the first valve body during transportation and press-fitting. The aforementioned second carrier groove effectively improves the positioning stability of the Y-shaped valve body, ensuring stable positioning of the second valve body during transportation and press-fitting.

[0015] Furthermore, the feeding section of the first valve body feeding mechanism is movably configured to move to a position corresponding to the first bearing groove, thereby feeding the first valve body into the first bearing groove; and / or, the grease application section of the valve body lubrication mechanism is movably configured to move to a position corresponding to the first bearing groove or a position corresponding to the second bearing groove; and / or, the feeding section of the valve core feeding mechanism is movably configured to move to a position corresponding to the first bearing groove or a position corresponding to the second bearing groove. This structural configuration allows for adaptive adjustments to the feeding sections of the first valve body feeding mechanism, the grease application section of the valve body lubrication mechanism, and the feeding section of the valve core feeding mechanism based on the positions of the first and second valve bodies, facilitating corresponding process operations on the first and second valve bodies respectively.

[0016] Furthermore, at least one of the valve body feeding mechanism, valve core feeding mechanism, and outer shell feeding mechanism includes: a feeding structure having a discharge channel; a transfer structure, at least a portion of which is adapted to the shape of the part to be fed, the transfer structure being rotatably configured, and having a first transfer position and a second transfer position; when the transfer structure is in the first transfer position, the gripping part of the transfer structure contacts the part to be fed at the discharge channel and removes the part to be fed through the gripping part of the transfer structure; when the transfer structure is in the second transfer position, the posture of the part to be fed on the transfer structure is adapted to the carrier; and a feeding structure being movably configured, the feeding structure being used to dock with the transfer structure in the second transfer position, the feeding part of the feeding structure transferring the part to be fed onto the carrier. This facilitates smooth and automated feeding from feeding to feeding onto the carrier, ensuring accurate feeding.

[0017] Furthermore, the feeding structure includes a Y-shaped valve body feeding gripper, which comprises a first gripping plate and a second gripping plate. The first gripping plate includes a first abutting plate and a second abutting plate spaced apart, and the second gripping plate includes a third abutting plate and a fourth abutting plate spaced apart. The first and third abutting plates are arranged opposite each other, forming a shape adapted to the first branch of the Y-shaped valve body for gripping the first branch. The second and fourth abutting plates are arranged opposite each other, forming a shape adapted to the second branch of the Y-shaped valve body for gripping the second branch. This structural arrangement facilitates improved feeding stability of the Y-shaped valve body and avoids mismatch between the Y-shaped valve body and the second bearing groove due to rotation during feeding, thereby improving the feeding accuracy of the Y-shaped valve body.

[0018] Furthermore, the assembly system also includes: a springback detection structure, located downstream of the valve core cutting mechanism; the springback detection structure includes a movable part and a detection part; the movable part is movably configured to apply pressure to the valve core; the detection part is positioned towards the movable part and is used to detect the position of the movable part; the springback detection structure has a pressing state and a springback detection state; when the springback detection structure is in the pressing state, the movable part presses the valve core downwards; when the springback detection structure is in the springback detection state, the movable part stops pressing the valve core, and the detection part determines whether the valve core has springed back by detecting the position of the movable part; and / or, a sheath feeding mechanism, located downstream of the valve core cutting mechanism, used to feed the sheath to the bottom of the main valve body. Thus, the springback detection structure facilitates the detection of whether the valve core has springed back after the valve core has been press-fitted, and determines the qualification of the press-fitting process based on the degree of springback. The sheath feeding structure facilitates the smooth feeding of the sheath to the bottom of the main valve body, improving the automation level of sheath feeding.

[0019] Furthermore, the conveying unit is a disc structure, rotatably arranged along its axis of symmetry. The valve body feeding mechanism, valve body lubrication mechanism, valve core feeding mechanism, valve core lubrication mechanism, outer shell feeding mechanism, pressing mechanism, and valve core cutting mechanism are spaced apart around the periphery of the disc structure. This structure is simple; the rotation of the disc structure allows the carrier component to switch to different workstations, moving to positions that connect with the valve body feeding mechanism, valve body lubrication mechanism, valve core feeding mechanism, valve core lubrication mechanism, outer shell feeding mechanism, pressing mechanism, and valve core cutting mechanism. This facilitates the automatic execution of main valve body feeding, main valve body lubrication, valve core feeding, valve core lubrication, outer shell feeding, pressing, and valve core cutting, thus completing the assembly process.

[0020] According to another aspect of the present invention, an assembly method is provided, applicable to the assembly system provided above. The assembly method includes: feeding a main valve body to a first feeding station; transporting the main valve body from the first feeding station to a first lubrication station and lubricating the main valve body at the first lubrication station; transporting the main valve body to a second feeding station and feeding a valve core onto the main valve body; transporting the main valve body and the valve core to a second lubrication station and lubricating the valve core at the second lubrication station; transporting the main valve body and the valve core to a third feeding station and feeding a housing onto the valve core; transporting the main valve body, the valve core, and the housing to a pressing station and pressing the housing onto the valve core and the main valve body at the pressing station; and transporting the main valve body, the valve core, and the housing to a cutting station downstream of the pressing station and cutting the valve core at the cutting station. This method facilitates the automation of processes such as main valve body loading, main valve body lubrication, valve core loading, valve core lubrication, outer shell loading, press fitting, and valve core cutting, reducing manual operations and lowering assembly costs.

[0021] Furthermore, before transporting the valve body, valve core, and housing to the cutting station downstream of the press-fitting station, the assembly method further includes: inspecting the press-fitting condition of the valve body, valve core, and housing to check whether they are tightly compressed; after cutting the valve core at the cutting station, the assembly method further includes: transporting the valve body, valve core, and housing to the ventilation test station, and pressing down the valve core at the ventilation test station to test its ventilation performance; after the ventilation performance test of the valve core is passed, the valve body, valve core, and housing are transported... The valve core is then transported to the springback testing station for springback testing. After the springback test is passed, the valve body, valve core, and outer shell are transported to the assembly station, where the sheath is assembled onto the bottom of the valve body. After the sheath assembly is complete, the assembled needleless connector is transported to the good product testing station. If the needleless connector is found to be a qualified product at the good product testing station, it is transported. If it is found to be a defective product at the good product testing station, it is unloaded. This method facilitates the efficient assembly of the valve body, valve core, outer shell, and sheath into a needleless connector, effectively ensuring the quality of the finished product.

[0022] By applying the technical solution of this invention, the conveying components can drive the carrier components to move between different workstations, completing the entire assembly process of the assembly system. The valve body feeding mechanism and valve body lubrication mechanism enable the feeding of the main valve body, followed by lubrication to facilitate subsequent assembly between the main valve body and other components. Similarly, the valve core feeding mechanism and valve core lubrication mechanism enable the feeding of the valve core, followed by lubrication to facilitate subsequent assembly between the valve core and other components. The housing feeding mechanism, pressing mechanism, and valve core cutting mechanism enable the feeding of the housing, followed by pressing between the housing and other components, and finally cutting of the valve core by the valve core cutting mechanism, ensuring the assembled structural components possess satisfactory performance. This assembly system improves the automation level of assembly, avoids the instability in assembly quality that may result from manual operation, and reduces labor costs. The valve body lubrication mechanism, valve core lubrication mechanism, and press-fit mechanism eliminate the need for welding when assembling the outer shell, main valve body, and valve core. The assembly is achieved solely through the press-fit mechanism, ensuring satisfactory assembly accuracy. This avoids the use of welding equipment in the assembly system, reducing its complexity and cost. Therefore, the assembly system provided by this invention solves the technical problem of excessively high assembly costs for needle-free connectors in existing technologies.

[0061] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0062] like Figures 1 to 21 As shown, Embodiment 1 of the present invention provides an assembly system, which includes a conveying assembly 1000, a valve body feeding mechanism 2000, a valve body lubrication mechanism 3000, a valve core feeding mechanism 4000, a valve core lubrication mechanism 5000, a housing feeding mechanism 6000, a pressing mechanism 7000, and a valve core cutting mechanism 8000. The conveying assembly 1000 includes a conveying section 1100 and a carrier member 1200. The conveying section 1100 is movably disposed and drives the carrier member 1200 to move. The valve body feeding mechanism 2000 and the valve body lubrication mechanism 3000 are both disposed on the side of the conveying assembly 1000. The valve body lubrication mechanism 3000 is located downstream of the valve body feeding mechanism 2000. The valve body feeding mechanism 2000 is used to feed the main valve body onto the carrier member 1200, and the valve body lubrication mechanism 3000 is used to lubricate the main valve body. Both the valve core feeding mechanism 4000 and the valve core lubrication mechanism 5000 are located on the side of the conveying assembly 1000. The valve core feeding mechanism 4000 is located downstream of the valve body lubrication mechanism 3000 to feed the valve core 130 onto the main valve body; the valve core lubrication mechanism 5000 is located downstream of the valve core feeding mechanism 4000 to lubricate the valve core 130. The outer casing feeding mechanism 6000, the pressing mechanism 7000, and the valve core cutting mechanism 8000 are all located on the side of the conveying assembly 1000. The outer casing feeding mechanism 6000 is located downstream of the valve core lubrication mechanism 5000 and is used to feed the outer casing 140 onto the valve core 130; the pressing mechanism 7000 is located downstream of the outer casing feeding mechanism 6000 to press the outer casing 140; and the valve core cutting mechanism 8000 is located downstream of the pressing mechanism 7000 to cut the valve core 130.

[0063] The assembly system provided in Embodiment 1 of this invention enables the conveying component 1000 to drive the carrier component 1200 to move between different workstations, completing the entire assembly process. The valve body feeding mechanism 2000 and the valve body lubrication mechanism 3000 enable the feeding of the main valve body, followed by lubrication to facilitate subsequent assembly between the main valve body and other components. Similarly, the valve core feeding mechanism 4000 and the valve core lubrication mechanism 5000 enable the feeding of the valve core 130, followed by lubrication to facilitate subsequent assembly between the valve core 130 and other components. The assembly system, comprising a housing loading mechanism 6000, a pressing mechanism 7000, and a valve core cutting mechanism 8000, enables the loading of the housing 140. After loading, the pressing mechanism 7000 presses the housing 140 against other components. Finally, the valve core cutting mechanism 8000 cuts the valve core 130, ensuring the assembled component possesses satisfactory performance. This assembly system enhances automation, avoids instability in assembly quality caused by manual operation, and reduces labor costs.

[0064] The valve body lubrication mechanism 3000, the valve core lubrication mechanism 5000, and the press-fitting mechanism 7000 eliminate the need for welding when assembling the housing 140, main valve body, and valve core 130. The press-fitting mechanism 7000 alone can press them together, achieving satisfactory assembly accuracy. This avoids the need for manual assembly with semi-automatic tooling or the use of welding equipment in the assembly system, thus reducing the complexity and cost of the assembly system. Therefore, the assembly system provided in this embodiment solves the technical problem of high assembly costs for needle-free connectors in the prior art.

[0065] Specifically, the press-fitting mechanism 7000 includes a force-applying component 7100 and a limiting component 7200. The force-applying component 7100 is movably disposed to approach or move away from the housing 140. The limiting component 7200 is movably disposed and spaced apart from the force-applying component 7100. The limiting component 7200 has a limiting groove 7211 that is adapted to at least a portion of the housing 140. The limiting component 7200 has a limiting position that allows the housing 140 to pass through the limiting groove 7211 and a clearance position spaced apart from the housing 140. When the limiting component 7200 is in the limiting position, the force-applying component 7100 applies a press-fitting force to the housing 140 to press the housing 140 onto the valve core 130. With this structural arrangement, the force-applying component 7100 can apply a press-fitting force to the housing 140, thereby enabling the housing 140 to be securely pressed onto the valve core 130, completing the assembly of the housing 140. The limiting component 7200 is designed to work in conjunction with the pressing operation of the force application component 7100, preventing damage to the housing 140 and / or the valve core 130. When the limiting component 7200 is in the limiting position, the housing 140 passes through the limiting groove 7211, which limits the movement of the housing 140, preventing excessive force on the housing 140 and / or the valve core 130 during the pressing process, thus avoiding wear or cracking. When the limiting component 7200 is in the clearance position, there is a certain gap between the housing 140 and the limiting component 7200, preventing obstruction of the movement of the carrier 1200, so that the carrier 1200 can carry the part to be pressed into the pressing station or move to other operating stations. The pressing mechanism 7000 ensures the accuracy of assembly, avoids the use of welding equipment, simplifies the complexity of the assembly system, and thus reduces the operating cost of the assembly system.

[0066] Specifically, after press-fitting, the outer shell 140 and the valve core 130 are interference-fitted, and the main valve body, valve core 130, and outer shell 140 are assembled to form a needle-free connector. Specifically, during the press-fitting process, the valve core 130 is first press-fitted onto the main valve body, and the outer shell 140 is then press-fitted onto the valve core 130, ultimately achieving the overall assembly of the main valve body, valve core 130, and outer shell 140.

[0067] Specifically, the force-applying assembly 7100 includes a first force-applying member 7110, which moves along a preset direction and abuts against the top of the housing 140 to directly press the housing 140 against the valve core 130 and the valve body. Alternatively, the force-applying assembly 7100 includes a first force-applying member 7110 and a second force-applying member 7120. The first force-applying member 7110 moves along a preset direction and abuts against the top of the housing 140. The second force-applying member 7120 is rotatably disposed on the side of the first force-applying member 7110 near the housing 140 and is clamped onto the outer wall of the housing 140. When the first force-applying member 7110 moves along the preset direction, the second force-applying member 7120 is rotatably disposed so that the housing 140 presses down onto the valve core 130 during rotation. With this structural arrangement, the force-applying component 7100 provides downward pressure to the housing 140 through the first force-applying element 7110 and rotational force to the housing 140 through the second force-applying element 7120. This allows the housing 140 to press down onto the valve core 130 during rotation, thereby buffering the downward pressing force of the housing 140 through rotation, further protecting the housing 140 and valve core 130 and preventing damage to them during the pressing process. Simultaneously, the rotational pressing method also further improves the accuracy of the pressing process, further ensuring the product's pass rate.

[0068] Specifically, the limiting assembly 7200 includes a limiting plate 7210 and a mounting plate 7220. The limiting plate 7210 is provided with a limiting groove 7211 and is located on the side of the force-applying assembly 7100 near the housing 140. The mounting plate 7220 is movably disposed along a preset direction and is connected to the limiting plate 7210. The limiting assembly 7200 also includes a first buffer 7230, which is disposed between the mounting plate 7220 and the limiting plate 7210, and the mounting plate 7220 is connected to the limiting plate 7210 through the first buffer 7230. With this structural arrangement, by setting the limiting assembly 7200 as a structure composed of the limiting plate 7210, the mounting plate 7220, and the first buffer 7230, it is possible to further buffer the downward pressure on the housing 140 through the first buffer 7230, further protecting the housing 140 and thus ensuring the product qualification rate.

[0069] Specifically, the mounting plate 7220 is provided with a clearance hole 7221, and the force-applying component 7100 also includes a force-applying body 7130. The force-applying body 7130 is movably inserted through the clearance hole 7221 in a preset direction. The first force-applying member 7110 is fixedly mounted on the force-applying body 7130 and located on the side of the mounting plate 7220 near the limiting plate 7210. The second force-applying member 7120 is rotatably mounted on the force-applying body 7130 and located on the side of the mounting plate 7220 near the limiting plate 7210. With this structural arrangement, the force-applying body 7130 is cleared through the clearance hole 7221, allowing the force-applying body 7130 to move vertically up and down, thereby driving the first force-applying member 7110 and the second force-applying member 7120 to apply a pressing force to the outer casing 140, realizing automated pressing and thus improving pressing efficiency.

[0070] Specifically, after the outer casing 140 is fully pressed onto the valve body, the auxiliary pushing structure lifts the limiting component 7200 to disengage it from the valve body. At this time, the first force-applying component 7110 and the second force-applying component 7120 still press against and hold the needleless connector material (including the outer casing 140, valve body, and valve core 130), preventing the entire needleless connector material from being lifted when the force-applying component 7100 is raised. Specifically, the auxiliary pushing structure can be a cylinder, which lifts the limiting component to disengage it from the valve body first.

[0071] In this embodiment, the pressing mechanism 7000 further includes a pushing assembly 7300, which is disposed on the side of the conveying section 1100 away from the carrier 1200. The pushing part of the pushing assembly 7300 is used to apply a pushing force to the conveying section 1100. When the force applying assembly 7100 applies a pressing force to the housing 140, the pushing assembly 7300 applies a pushing force to the conveying section 1100. With this structural arrangement, when the force applying assembly 7100 applies a downward pressing force to the housing 140, the pushing assembly 7300 can provide an upward pushing force, preventing excessive pressure during the downward pressing process of the force applying assembly 7100 from causing deformation or imbalance of the conveying section 1100, thus ensuring the smooth operation of the conveying section 1100 and guaranteeing the overall operational stability of the assembly system.

[0072] Specifically, the pushing assembly 7300 is provided with a reset member 7310, which provides a downward reset force to the pushing assembly 7300 so that the pushing assembly 7300 can push under the driving action, or reset to a position spaced apart from the conveying section 1100 when the driving action stops. Specifically, the force application assembly 7100 and the limiting assembly 7200 are located above the conveying section 1100, and the pushing assembly 7300 is located below the conveying section 1100.

[0073] Specifically, at least a portion of the force-applying component 7100 is connected to at least a portion of the limiting component 7200, so that when the limiting component 7200 moves to the limiting position, the force-applying component 7100 is driven to move synchronously towards the housing 140. In this way, the connection between at least a portion of the force-applying component 7100 and at least a portion of the limiting component 7200 allows for better cooperation between them. When the limiting component 7200 moves to the limiting position, the force-applying component 7100 can simultaneously begin to move towards the housing 140, avoiding wasted time and thus improving pressing efficiency.

[0074] In this embodiment, the valve body lubrication mechanism 3000 and / or the valve core lubrication mechanism 5000 include a grease-applying structure and a grease-pushing structure. The grease-applying structure is movably configured to move to a grease-taking position that contacts solid grease and a grease-applying position that contacts the main valve body and / or valve core 130. The grease-pushing structure moves in a direction close to or away from the grease-applying structure and is used to push the solid grease to move in a direction close to the grease-applying structure. With this structural configuration, the grease-applying structure can be used to grease the main valve body or valve core 130. When the grease-applying structure is in the grease-taking position, it is in contact with the solid grease, causing some of the solid grease to adhere to the grease-applying structure. When the grease-applying structure is in the grease-applying position, it is in contact with the main valve body or valve core 130, causing the solid grease adhering to the grease-applying structure to be applied to the surface of the main valve body or valve core 130. When the grease coating structure cannot reach enough solid grease, the movement of the pusher structure can push the solid grease to move in a direction closer to the grease coating structure, so that the grease coating structure can reach enough solid grease, thereby ensuring the stable progress of the grease coating operation and improving grease coating efficiency.

[0075] Specifically, the solid grease has a columnar structure, and the grease application structure includes a first grease applicator and a second grease applicator. The grease application structure has an open state and a closed state. When the grease application structure is in the open state, the first and second grease applicators are respectively used to clamp onto both sides of the solid grease and contact it, or the first and second grease applicators are respectively used to clamp onto both sides of the main valve body and / or valve core 130 and contact it. In this way, when the grease application structure is in the open state, the first and second grease applicators can be moved along the direction closer to or away from the solid grease to achieve grease collection, or the first and second grease applicators can be moved along the direction closer to or away from the main valve body and / or valve core 130 to achieve grease application to the main valve body and / or valve core 130. The operation is simple and easy to implement, which helps to reduce the cost of grease application.

[0076] Specifically, the grease-applying structure is a gripper structure, with the first grease-applying component and the second grease-applying component being the two gripper arms of the gripper structure.

[0077] Specifically, there are multiple solid greases, and the feeding structure synchronously pushes multiple solid greases to move. There are also multiple grease coating structures, each corresponding to one of the multiple solid greases. Each grease coating structure is used to collect the corresponding solid grease. The multiple grease coating structures are used to apply grease to multiple valve cores 130 and / or the main valve body. In this way, the corresponding arrangement of multiple grease coating structures with multiple solid greases helps to improve grease coating efficiency.

[0078] Specifically, the valve body lubrication mechanism 3000 and / or the valve core lubrication mechanism 5000 further include a storage structure. The storage structure has a protective channel adapted to solid grease, through which the solid grease passes. One end of the solid grease extends beyond one end of the protective channel to be at least partially opposite to the pusher structure, and the other end extends beyond the other end of the protective channel to cooperate with the grease coating structure. In this way, the storage structure protects the solid grease, thereby ensuring that the solid grease can be stably pushed out of the storage structure under the action of the pusher structure.

[0079] Specifically, the valve body lubrication mechanism 3000 includes a first grease-applying structure 3100 and a first pusher structure 3200. The first grease-applying structure 3100 is movably configured to move to a grease-taking position that contacts the first solid grease 3300 and a grease-applying position that contacts the main valve body. The first pusher structure 3200 moves in a direction close to or away from the first grease-applying structure 3100 and is used to push the first solid grease 3300 to move in a direction close to the first grease-applying structure 3100. With this structural arrangement, the main valve body can be greased via the first grease-applying structure 3100. When the first grease-applying structure 3100 is in the grease-collecting position, it contacts the first solid grease 3300, allowing some of the grease to adhere to it. When the first grease-applying structure 3100 is in the grease-applying position, it contacts the valve body, allowing the solid grease adhering to it to be applied to the surface of the main valve body. When the first grease-applying structure 3100 cannot reach sufficient amounts of the solid grease 3300, the first pusher structure 3200 can move the solid grease 3300 closer to the first grease-applying structure 3100, ensuring that the first grease-applying structure 3100 reaches sufficient amounts of the solid grease, thus guaranteeing stable grease application and improving grease-applying efficiency.

[0080] Specifically, the first solid grease 3300 has a columnar structure, and the first grease coating structure 3100 includes a first valve body grease coating component 3110 and a second valve body grease coating component 3120. The first grease coating structure 3100 has an open state and a closed state. When the first grease coating structure 3100 is in the open state, the first valve body grease coating component 3110 and the second valve body grease coating component 3120 are respectively used to clamp on both sides of the first solid grease 3300 and contact the first solid grease 3300, or the first valve body grease coating component 3110 and the second valve body grease coating component 3120 are respectively used to clamp on both sides of the valve body and contact the valve body. In this way, when the first grease coating structure 3100 is in the open state, the first valve body grease coating component 3110 and the second valve body grease coating component 3120 can be moved in a direction close to or away from the first solid grease 3300 to achieve grease collection. Alternatively, the first grease coating structure 3100 can be moved in a direction close to or away from the main valve body to achieve grease application to the main valve body. The operation is simple and easy to implement, which helps to reduce the cost of grease coating operation.

[0081] Specifically, there are multiple first solid greases 3300, and the first pushing structure 3200 synchronously pushes the multiple first solid greases 3300 to move. There are also multiple first grease coating structures 3100, which are arranged one-to-one with the multiple first solid greases 3300. Each first grease coating structure 3100 is used to take grease from its corresponding first solid grease 3300. The multiple first grease coating structures 3100 are used to grease multiple main valve bodies. In this way, the corresponding arrangement of multiple first grease coating structures 3100 and multiple first solid greases 3300 helps to improve the grease coating efficiency of the main valve bodies.

[0082] Specifically, the valve body lubrication mechanism 3000 further includes a first storage structure 3400. The first storage structure 3400 has a first storage protection channel adapted to the first solid grease 3300. The first solid grease 3300 passes through the first storage protection channel, with one end extending out of the first storage protection channel to be positioned opposite at least a portion of the first pusher structure 3200, and the other end extending out of the first storage protection channel to cooperate with the first grease coating structure 3100. In this way, the first storage structure 3400 can protect the first solid grease 3300, thereby ensuring that the first solid grease 3300 can be stably pushed out of the first storage structure 3400 under the action of the first pusher structure 3200.

[0083] Specifically, the valve core lubrication mechanism 5000 includes a second grease-applying structure and a second pusher structure. The second grease-applying structure is movably configured to move to a grease-taking position that contacts the second solid grease and a grease-applying position that contacts the valve core 130. The second pusher structure moves in a direction close to or away from the second grease-applying structure, and is used to push the second solid grease to move in a direction close to the second grease-applying structure. With this structural configuration, the valve core 130 can be greased by the second grease-applying structure. When the second grease-applying structure is in the grease-taking position, it is in contact with the second solid grease, causing some of the second solid grease to adhere to the second grease-applying structure. When the second grease-applying structure is in the grease-applying position, it is in contact with the valve core 130, causing the solid grease adhering to the second grease-applying structure to be applied to the surface of the valve core 130. When the second grease coating structure cannot reach enough of the second solid grease, the movement of the second pusher structure can push the second solid grease to move in a direction closer to the second grease coating structure, so that the second grease coating structure can reach enough of the second solid grease, thereby ensuring the stable progress of the grease coating operation and improving the grease coating efficiency.

[0084] Specifically, the second solid grease has a columnar structure, and the second grease coating structure includes a first valve core grease coating component and a second valve core grease coating component. The second grease coating structure has an open state and a closed state. When the second grease coating structure is in the open state, the first and second valve core grease coating components are respectively used to clamp onto both sides of the second solid grease and contact it, or the first and second valve core grease coating components are respectively used to clamp onto both sides of the valve core 130 and contact it. In this way, when the second grease coating structure is in the open state, the first and second valve core grease coating components can be moved along the direction closer to or away from the second solid grease to achieve grease collection, or the first and second valve core grease coating components can be moved along the direction closer to or away from the valve core 130 to achieve grease application to the valve core 130. The operation is simple and easy to implement, which helps to reduce the cost of grease coating operations.

[0085] Specifically, there are multiple second solid greases, and the second pushing structure synchronously pushes multiple second solid greases to move. There are also multiple second grease coating structures, each corresponding to one of the multiple second solid greases. Each second grease coating structure is used to take grease from its corresponding second solid grease. The multiple second grease coating structures are used to apply grease to multiple valve cores 130. In this way, the corresponding arrangement of multiple second grease coating structures with multiple second solid greases helps to improve grease coating efficiency.

[0086] Specifically, the valve core lubrication mechanism 5000 further includes a second storage structure. The second storage structure has a second storage protection channel adapted to the second solid grease. The second solid grease passes through the second storage protection channel, with one end extending out of the channel to be at least partially opposite to the second pusher structure, and the other end extending out of the channel to cooperate with the second grease coating structure. In this way, the second storage structure protects the second solid grease, ensuring that it can be stably pushed out of the storage structure under the action of the second pusher structure.

[0087] In this embodiment, the valve body feeding mechanism 2000 includes a first valve body feeding mechanism 2100 and a second valve body feeding mechanism 2200 arranged at intervals. The first valve body feeding mechanism 2100 is used to feed the first valve body 110, and the second valve body feeding mechanism 2200 is used to feed the second valve body 120. The carrier 1200 is provided with a first carrier groove 1210 and a second carrier groove 1220. The first carrier groove 1210 is adapted to the first valve body 110. The first valve body 110 is fed into the first carrier groove 1210, and the second valve body 120 is fed into the second carrier groove 1220. With this structural configuration, the first valve body 110 and the second valve body 120 can be fed by the first valve body feeding mechanism 2100 and the second valve body feeding mechanism 2200 respectively, and the first valve body 110 and the second valve body 120 can be supported by the first bearing groove 1210 and the second bearing groove 1220 respectively, so as to drive the first valve body 110 and the second valve body 120 to move between different work stations, thereby ensuring the stable operation of the assembly system.

[0088] Specifically, the first valve body 110 is a straight valve body, and the carrier 1200 is provided with a limiting gripper 1230. The limiting gripper 1230 is adapted to the shape of the straight valve body and is closable on the carrier 1200. When the straight valve body is fed into or unloaded from the first carrier groove 1210, the limiting gripper 1230 opens; when the straight valve body is installed in the first carrier groove 1210, the limiting gripper 1230 closes. With this structural arrangement, the first valve body 110 can be positioned by the limiting gripper 1230, preventing displacement of the first valve body 110 during the movement of the carrier 1200, which would affect the accuracy of press-fitting, thereby improving the assembly accuracy of the assembly system and ensuring the product qualification rate.

[0089] Specifically, the limiting gripper 1230 also includes a pusher 1231, which is movably disposed on one side of the limiting gripper 1230 and is used to control the opening and closing of the limiting gripper 1230.

[0090] Specifically, the conveying section 1100 is provided with a push drive 1110, which is arranged opposite to the pusher 1231 so as to drive the pusher 1231 through the push drive 1110 to realize the opening and closing of the limit gripper 1230.

[0091] Specifically, the push drive component 1110 is a cylinder.

[0092] Specifically, the second valve body 120 is a Y-shaped valve body, and the shape of the second bearing groove 1220 is adapted to the bifurcation of the Y-shaped valve body. In this way, the periphery of the second bearing groove 1220 can abut and position the shape of the bifurcation of the Y-shaped valve body, preventing the second valve body 120 from shifting during the movement of the bearing component 1200, which would affect the accuracy of press-fitting, thereby improving the assembly accuracy of the assembly system and ensuring the product qualification rate.

[0093] Specifically, the second bearing groove 1220 is shaped like a gourd, and the second valve body 120 can be stably limited through the second bearing groove 1220.

[0094] Specifically, the feeding section of the first valve body feeding mechanism 2100 is movably configured so that it moves to a position corresponding to the first bearing groove 1210, thereby feeding the first valve body 110 into the first bearing groove 1210. This allows the first valve body 110 to be accurately fed into the first bearing groove 1210 via the feeding section of the first valve body feeding mechanism 2100, improving the automation level of the feeding operation, reducing the misfeeding rate, and thus ensuring the product qualification rate.

[0095] Specifically, the grease application section of the valve body lubrication mechanism 3000 is movably configured so that it can move to a position corresponding to the first bearing groove 1210 or a position corresponding to the second bearing groove 1220. This allows for separate grease application to the first valve body 110 and the second valve body 120 via the grease application section of the valve body lubrication mechanism 3000, improving the automation level and accuracy of the grease application operation, thereby ensuring a high product qualification rate.

[0096] Specifically, the feeding section of the valve core feeding mechanism 4000 is movably configured so that it can move to a position corresponding to the first bearing groove 1210 or the second bearing groove 1220. This allows the valve core 130 to be accurately fed into the corresponding position of the first bearing groove 1210 or the second bearing groove 1220 via the feeding section of the valve core feeding mechanism 4000, improving the automation level of the feeding operation, reducing the misfeeding rate, and thus ensuring the product qualification rate.

[0097] In this embodiment, at least one of the valve body feeding mechanism 2000, the valve core feeding mechanism 4000, and the outer shell feeding mechanism 6000 includes a feeding structure, a transfer structure, and a feeding structure. The feeding structure has a discharge channel. At least a portion of the transfer structure is adapted to the shape of the part to be fed, and the transfer structure is rotatably configured. The transfer structure has a first transfer position and a second transfer position. When the transfer structure is in the first transfer position, the gripping part of the transfer structure contacts the part to be fed at the discharge channel and removes the part to be fed through the gripping part of the transfer structure. When the transfer structure is in the second transfer position, the posture of the part to be fed on the transfer structure is adapted to the carrier 1200. The feeding structure is movably configured and is used to dock with the transfer structure in the second transfer position. The feeding part of the feeding structure transfers the part to be fed onto the carrier 1200. This structural setup allows for improved automation of the feeding operation through the coordinated use of the feeding, transfer, and loading structures, reducing manual intervention and thus lowering production costs and increasing loading efficiency.

[0098] Specifically, the feeding structure may include a spiral vibratory feeder structure. The transfer structure can reach the second transfer position by rotating a predetermined angle at the first transfer position. The predetermined structure can be determined according to the angle between the posture of the part to be loaded at the discharge channel position and the posture of the part to be loaded in the carrier 1200, and can be 90°, 180° or other angles.

[0099] Specifically, the feeding structure has a first feeding position and a second feeding position. When the feeding structure is in the first feeding position, the feeding part of the feeding structure moves to the position corresponding to the first bearing groove 1210, transferring the part to be fed to the corresponding position of the first bearing groove 1210. When the feeding structure is in the second feeding position, the feeding part of the feeding structure moves to the position corresponding to the second bearing groove 1220, transferring the part to be fed to the corresponding position of the second bearing groove 1220. In this way, the first valve body 110 can be smoothly fed into the first bearing groove 1210, and the second valve body 120 can be smoothly fed into the second bearing groove 1220, thereby improving the feeding accuracy.

[0100] Specifically, the first valve body feeding mechanism 2100 includes a first valve body feeding structure 2110, a first valve body transfer structure 2120, and a first valve body feeding structure 2130. The first valve body feeding structure 2110 has a first valve body discharge channel 2111. At least a portion of the first valve body transfer structure 2120 is adapted to the shape of the first valve body 110. The first valve body transfer structure 2120 is rotatably disposed and has a first valve body first transfer position and a first valve body second transfer position. When the first valve body transfer structure 2120 is in the first valve body first transfer position, the clamping part of the first valve body transfer structure 2120 is in contact with the first valve body 110 at the first valve body discharge channel 2111, and the clamping part of the first valve body transfer structure 2120 is used to remove the first valve body 110 to be loaded. When the first valve body transfer structure 2120 is in the first valve body second transfer position, the posture of the first valve body 110 on the first valve body transfer structure 2120 is adapted to the bearing member 1200. The first valve body feeding structure 2130 is movably configured to dock with the first valve body transfer structure 2120 located at the second transfer position of the first valve body. The feeding section of the first valve body feeding structure 2130 transfers the first valve body 110 onto the carrier 1200. This structural configuration, through the cooperation of the first valve body feeding structure 2110, the first valve body transfer structure 2120, and the first valve body feeding structure 2130, improves the automation level of the feeding operation, reduces manual intervention, thereby lowering production costs and increasing feeding efficiency.

[0101] Specifically, the second valve body feeding mechanism 2200 includes a second valve body feeding structure 2210, a second valve body transfer structure 2220, and a second valve body feeding structure 2230. The second valve body feeding structure 2210 has a second valve body discharge channel 2211. At least a portion of the second valve body transfer structure 2220 is adapted to the shape of the second valve body 120. The second valve body transfer structure 2220 is rotatably disposed and has a first transfer position and a second transfer position. When the second valve body transfer structure 2220 is in the first transfer position, the gripping part of the second valve body transfer structure 2220 is in contact with the second valve body 120 at the discharge channel 2211 of the second valve body, and the gripping part of the second valve body transfer structure 2220 is used to remove the second valve body 120 to be loaded. When the second valve body transfer structure 2220 is in the second transfer position, the posture of the second valve body 120 on the second valve body transfer structure 2220 is adapted to the bearing member 1200. The second valve body feeding structure 2230 is movably configured to dock with the second valve body transfer structure 2220 located at the second transfer position of the second valve body. The feeding section of the second valve body feeding structure 2230 transfers the second valve body 120 onto the carrier member 1200. This structural configuration, through the cooperation of the second valve body feeding structure 2210, the second valve body transfer structure 2220, and the second valve body feeding structure 2230, improves the automation level of the feeding operation, reduces manual intervention, thereby lowering production costs and increasing feeding efficiency.

[0102] Specifically, the second valve body feeding structure 2210 includes a second valve body discharge detection element 2212. The second valve body discharge detection element 2212 is disposed on one side of the second valve body discharge channel 2211 and faces the second valve body discharge channel 2211. The second valve body discharge detection element 2212 is used to detect whether there is a second valve body 120 at the discharge port of the second valve body discharge channel 2211. When the second valve body discharge detection element 2212 detects that there is a second valve body 120 at the discharge port of the second valve body discharge channel 2211, the second valve body transfer structure 2220 starts to operate; when the second valve body discharge detection element 2212 does not detect that there is a second valve body 120 at the discharge port of the second valve body discharge channel 2211, the second valve body transfer structure 2220 will not start to operate, and the second valve body feeding structure 2210 starts to operate and feed material.

[0103] Specifically, the second valve body discharge detection element 2212 can be a material sensing element.

[0104] In this embodiment, the valve core feeding mechanism 4000 includes a valve core feeding structure 4100, a valve core transfer structure 4200, and a valve core feeding structure 4300. The valve core feeding structure 4100 has a valve core discharge channel 4110. At least a portion of the valve core transfer structure 4200 is adapted to the shape of the valve core 130. The valve core transfer structure 4200 is rotatably configured and has a first valve core transfer position and a second valve core transfer position. When the valve core transfer structure 4200 is in the first valve core transfer position, the clamping part of the valve core transfer structure 4200 is in contact with the valve core 130 at the valve core discharge channel 4110, and the valve core 130 to be loaded is taken away through the clamping part of the valve core transfer structure 4200. When the valve core transfer structure 4200 is in the second valve core transfer position, the posture of the valve core 130 on the valve core transfer structure 4200 is adapted to the bearing member 1200. The valve core feeding structure 4300 is movably configured to dock with the valve core transfer structure 4200, which is located at the second transfer position of the valve core. The feeding section of the valve core feeding structure 4300 transfers the valve core 130 onto the carrier 1200. This structural arrangement, through the cooperation of the valve core feeding structure 4100, the valve core transfer structure 4200, and the valve core feeding structure 4300, improves the automation level of the feeding operation, reduces manual intervention, and thus lowers production costs and increases feeding efficiency.

[0105] Specifically, the valve core transfer structure 4200 is provided with a valve core take-up head, which is used to insert into the valve core 130 and expand the valve core 130 to take away the valve core 130 at the valve core discharge channel 4110.

[0106] Specifically, the valve core feeding structure 4100 includes a valve core discharge detection element 4120, which is disposed on one side of the valve core discharge channel 4110 and faces the valve core discharge channel 4110. It is used to detect whether a valve core 130 is present in the valve core discharge channel 4110. When the valve core discharge detection element 4120 detects a valve core 130 in the valve core discharge channel 4110, the valve core transfer structure 4200 starts operating; when the valve core discharge detection element 4120 does not detect a valve core 130 in the valve core discharge channel 4110, the valve core transfer structure 4200 does not start operating, and the valve core feeding structure 4100 starts operating and feeding.

[0107] Specifically, the valve core feeding structure 4100 also includes a valve core picking detection element 4130, which is positioned towards the valve core discharge channel 4110 to detect whether the valve core 130 at the valve core discharge channel 4110 has been removed. When the valve core picking detection element 4130 detects a valve core 130 at the valve core discharge channel 4110, the valve core transfer structure 4200 continues to operate; when the valve core picking detection element 4130 does not detect a valve core 130 at the valve core discharge channel 4110, the valve core transfer structure 4200 stops operating.

[0108] Specifically, the valve core material detection component 4130 is a vacuum sensor.

[0109] Specifically, the valve core feeding structure 4300 includes a valve core feeding gripper 4310 and a valve core feeding pressure plate 4320. The valve core feeding gripper 4310 includes a first gripper and a second gripper arranged opposite to each other. The first gripper and the second gripper form a shape adapted to the valve core 130 to clamp the valve core 130. The valve core feeding pressure plate 4320 is disposed between the first gripper and the second gripper. The valve core feeding pressure plate 4320 has a pressing position that presses against the clamped valve core 130 and avoids being clamped. The valve core 130 is positioned in a clearance position. When the valve core feeding plate 4320 is in the clearance position, there is a certain distance between the valve core feeding plate 4320 and the first and second grippers, so that the first and second grippers can grip the valve core 130. When the valve core feeding plate 4320 is in the pressing position, the valve core feeding plate 4320 abuts against the upper end of the clamped valve core 130 to achieve positioning of the valve core 130 and prevent the valve core 130 from tilting or slipping during movement.

[0110] Specifically, the outer shell feeding mechanism 6000 includes an outer shell feeding structure 6100, a transfer structure, and an outer shell loading structure 6200. The outer shell feeding structure 6100 has an outer shell discharge channel 6110. At least a portion of the transfer structure is adapted to the shape of the outer shell, and the transfer structure is rotatably configured. The transfer structure has a first outer shell transfer position and a second outer shell transfer position. When the transfer structure is in the first outer shell transfer position, the gripping part of the transfer structure engages with the outer shell 140 at the outer shell discharge channel 6110, and removes the outer shell 140 to be loaded through the gripping part of the transfer structure. When the transfer structure is in the second outer shell transfer position, the posture of the outer shell 140 on the transfer structure is adapted to the carrier member 1200. The outer shell loading structure 6200 is movably configured and is used to dock with the transfer structure in the second outer shell transfer position. The loading part of the outer shell loading structure 6200 transfers the outer shell 140 onto the carrier member 1200. By adopting this structural configuration, the automation level of the feeding operation can be improved and manual intervention can be reduced through the cooperation of the outer shell feeding structure 6100, the transfer structure and the outer shell loading structure 6200, thereby reducing production costs and improving feeding efficiency.

[0111] Specifically, the Y-shaped valve body includes a main body, a first branch, and a second branch. The main body, the first branch, and the second branch are all strip-shaped structures. The ends of the first branch and the second branch are connected to the same end of the main body to form a Y-shaped structure.

[0112] Specifically, the second valve body feeding structure 2230 includes a Y-shaped valve body feeding gripper 2231. The Y-shaped valve body feeding gripper 2231 includes a first clamping plate 22311 and a second clamping plate 22312. The first clamping plate 22311 includes a first abutting plate 223111 and a second abutting plate 223112 spaced apart. The second clamping plate 22312 includes a third abutting plate 223121 and a fourth abutting plate 223122 spaced apart. The first abutment plate 223111 and the third abutment plate 223121 are arranged opposite to each other, forming a shape adapted to the first branch of the Y-shaped valve body for clamping. The second abutment plate 223112 and the fourth abutment plate 223122 are arranged opposite to each other, forming a shape adapted to the second branch of the Y-shaped valve body for clamping. This structural arrangement allows for stable clamping of the first and second branches of the Y-shaped valve body by the first clamping plate 22311 and the second clamping plate 22312, achieving positioning of the Y-shaped valve body during clamping and movement, preventing displacement of the Y-shaped valve body during movement, thus ensuring efficient docking with the carrier 1200 and consequently ensuring efficient product assembly.

[0113] In this embodiment, the assembly system further includes a springback detection structure 9000, which is located downstream of the valve core cutting mechanism 8000. The springback detection structure 9000 includes a movable member 9100 and a detection member 9200. The movable member 9100 is movably disposed and is used to apply pressure to the valve core 130. The detection member 9200 is disposed toward the movable member 9100 and is used to detect the position of the movable member 9100. The springback detection structure 9000 has a pressing state and a springback detection state. When the springback detection structure 9000 is in the pressing state, the movable member 9100 presses down on the valve core 130. When the springback detection structure 9000 is in the springback detection state, the movable member 9100 stops pressing down on the valve core 130, and the detection member 9200 determines whether the valve core 130 has springbacked by detecting the position of the movable member 9100. With this structural setup, the assembly effect of the product can be detected through the moving part 9100 and the inspection part 9200, thereby identifying defective products as early as possible and ensuring the product pass rate.

[0114] Specifically, the springback detection structure 9000 also includes a drive device, which is drivenly connected to the movable member 9100 to press the movable member 9100 downwards. When the springback detection structure 9000 is in the springback detection state, the drive device resets, and the movable member 9100 moves upwards under the lifting action of the valve core 130. The detection member 9200 determines whether the movable member 9100 has risen to a preset height by detecting the position of the movable member 9100, thereby determining whether the valve core 130 has springbacked.

[0115] Specifically, the driving device is a cylinder.

[0116] In this embodiment, the assembly system also includes a sheath feeding mechanism 10000, which is located downstream of the valve core cutting mechanism 8000. The sheath feeding mechanism 10000 is used to feed the sheath 150 to the bottom of the main valve body.

[0117] Specifically, the sheath feeding mechanism 10000 includes a sheath feeding structure 10100, a sheath transfer structure 10200, a sheath feeding structure 10300, and a sheath pushing structure 10400. The sheath feeding structure 10100 has a sheath discharge channel 10110. At least a portion of the sheath transfer structure 10200 is adapted to the shape of the sheath 150. The sheath transfer structure 10200 is rotatably configured and has a first transfer position and a second transfer position. When the sheath transfer structure 10200 is in the first transfer position, the gripping part of the sheath transfer structure 10200 contacts the sheath 150 at the sheath discharge channel 10110 and removes the sheath 150 through the gripping part of the sheath transfer structure 10200. When the sheath transfer structure 10200 is in the second transfer position, the posture of the sheath 150 on the sheath transfer structure 10200 is adapted to the sheath pushing structure 10400. The sheath feeding structure 10300 is movably configured to dock with the sheath transfer structure 10200, which is located at the second transfer position of the sheath. The feeding part of the sheath feeding structure 10300 transfers the sheath 150 onto the sheath pushing structure 10400. The sheath pushing structure 10400 is also movably configured to dock with the bottom of the carrier 1200. The pushing part of the sheath pushing structure 10400 pushes the sheath 150 from bottom to top onto the carrier 1200. This structural configuration, through the cooperation of the sheath feeding structure 10100, the sheath transfer structure 10200, the sheath feeding structure 10300, and the sheath pushing structure 10400, improves the automation level of the feeding operation, reduces manual intervention, and thus lowers production costs and increases feeding efficiency.

[0118] Specifically, the sheath feeding mechanism 10000 also includes a sheath pushing and limiting structure 10500. The sheath pushing and limiting structure 10500 is located on the side of the sheath feeding mechanism 10000 away from the sheath pushing structure 10400. The sheath pushing and limiting structure 10500 includes a sheath pushing and limiting plate 10510, and the abutment portion of the sheath pushing and limiting plate 10510 is used to apply downward pressure to the carrier 1200. When the sheath pushing structure 10400 pushes the sheath 150 from bottom to top, the sheath pushing and limiting structure 10500 applies downward pressure to the carrier 1200. With this structural design, when the sheath jacking structure 10400 pushes the sheath 150 from bottom to top, the sheath jacking limiting structure 10500 can provide downward pressure to prevent the load-bearing component 1200 from being lifted due to excessive jacking force during the jacking process of the sheath jacking structure 10400, thereby ensuring the overall operational stability of the assembly system.

[0119] In this embodiment, the conveying unit 1100 is a disc structure, rotatably arranged along its axis of symmetry. The valve body feeding mechanism 2000, valve body lubrication mechanism 3000, valve core feeding mechanism 4000, valve core lubrication mechanism 5000, outer shell feeding mechanism 6000, pressing mechanism 7000, and valve core cutting mechanism 8000 are spaced apart around the periphery of the disc structure. This structural arrangement allows the already unloaded carrier component 1200 to directly enter the next feeding station without the need for a separate transport mechanism, thus improving assembly efficiency. Simultaneously, the spaced arrangement of each device around the periphery of the disc structure reduces the area occupied by the overall assembly system, thereby improving factory space utilization and reducing production costs.

[0120] In this embodiment, the valve core cutting mechanism 8000 includes a cutting structure 8100, which is movably disposed, and a cutting head 8110 is provided at the end of the cutting structure 8100. The cutting structure 8100 has a cutting position for cutting the valve core 130 and a clearance position for avoiding the valve core 130. When the cutting structure 8100 is in the cutting position, the cutting head 8110 presses against the valve core 130 to cut the valve core 130. When the cutting structure 8100 is in the clearance position, the cutting head 8110 and the valve core 130 are spaced apart to allow the carrier 1200 carrying the valve core 130 to enter or leave the valve core cutting mechanism 8000. This facilitates the cutting of the valve core 130.

[0121] Specifically, the cutting structure 8100 includes multiple cutting heads 8110, each of which is configured in a one-to-one correspondence with the valve core 130 carried on the carrier 1200.

[0122] In this embodiment, the assembly system further includes a ventilation detection mechanism 11000, which is located downstream of the valve core cutting mechanism 8000 and upstream of the springback detection structure 9000. The ventilation detection mechanism 11000 includes a ventilation detection element 11100, which is positioned toward the support element 1200. The ventilation detection component 11100 includes a ventilation detection head 11110, which is movably mounted on the ventilation detection component 11100. The ventilation detection head 11110 has a detection position for engaging the valve core 130 and a clearance position for avoiding the valve core 130. When the ventilation detection head 11110 is in the detection position, it vents air into the valve core 130 to detect whether the gas flow is normal and whether the valve core 130 is cut properly. When the ventilation detection head 11110 is in the clearance position, there is a certain distance between the ventilation detection head 11110 and the valve core 130 so that the carrier 1200 carrying the valve core 130 can enter or leave the ventilation detection mechanism 11000.

[0123] Specifically, the ventilation detection head 11110 is provided with a second buffer 11111, so that when the ventilation detection head 11110 moves to the detection position, the second buffer 11111 buffers the impact force generated on the valve core 130, thereby protecting the valve core 130.

[0124] Specifically, the end of the ventilation detection head 11110 is provided with a ventilation detection abutment part 11112 for abutting against the upper end face of the valve core 130. The ventilation detection head 11110 also includes a ventilation detection pressing part 11113 and an air passage 11114. The ventilation detection pressing part 11113 protrudes from the ventilation detection abutment part 11112 and is used to compress the valve core 130 to deform it. The air passage 11114 is disposed inside the ventilation detection head 11110 and is used to introduce gas into the valve core 130 to detect the ventilation of the valve core 130.

[0125] Specifically, the ventilation detection component 11100 includes multiple ventilation detection heads 11110, each ventilation detection head 11110 being configured in a one-to-one correspondence with the valve core 130 carried on the carrier component 1200.

[0126] like Figure 22As shown, Embodiment 2 of the present invention provides an assembly method applicable to the assembly system provided in Embodiment 1 above. The assembly method includes: loading the main valve body to a first loading station; transporting the main valve body from the first loading station to a first lubrication station; and lubricating the main valve body at the first lubrication station; transporting the main valve body to a second loading station and loading the valve core 130 onto the main valve body; and transporting the main valve body and the valve core 130 to the second lubrication station, and lubricating the main valve body at the second lubrication station. At the lubrication station, the valve core 130 is lubricated; the main valve body and valve core 130 are transported to the third loading station, and the outer shell 140 is loaded onto the valve core 130; the main valve body, valve core 130, and outer shell 140 are transported to the pressing station, where the outer shell 140 is pressed onto the valve core 130 and the main valve body; the main valve body, valve core 130, and outer shell 140 are transported to the cutting station downstream of the pressing station, where the valve core 130 is cut. Using this assembly method, through the setting of the first and second lubrication stations, the main valve body, valve core 130, and outer shell 140 can be directly press-fitted together by the pressing mechanism of the pressing station without the need for welding equipment, thereby reducing the equipment complexity of the assembly system and lowering production costs.

[0127] Before transporting the valve body, valve core 130, and housing 140 to the cutting station downstream of the press-fitting station, the assembly method further includes: inspecting the press-fitting condition of the valve body, valve core 130, and housing 140 to check whether the valve body, valve core 130, and housing 140 are tightly pressed; after cutting the valve core 130 at the cutting station, the assembly method further includes: transporting the valve body, valve core 130, and housing 140 to the ventilation test station, and pressing down the valve core 130 at the ventilation test station to test the ventilation performance of the valve core 130; after the ventilation performance of the valve core 130 is qualified, the valve body, valve core 130, and housing 140 are assembled. The valve core 130 and housing 140 are transported to the springback testing station, where the springback test is performed on the valve core 130. After the springback test of the valve core 130 is passed, the valve body, valve core 130, and housing 140 are transported to the assembly station, where the sheath 150 is assembled to the bottom of the valve body. After the assembly of the sheath 150 is completed, the assembled needleless connector is transported to the good product testing station. When the needleless connector is detected as a qualified product at the good product testing station, it is transported. When the needleless connector is detected as a defective product at the good product testing station, it is unloaded. This method facilitates the efficient assembly of the valve body, valve core 130, housing 140, and sheath 150 into a needleless connector and effectively ensures the finished quality of the needleless connector.

[0128] Specifically, the operation process of the pressing mechanism 7000 at the pressing station is as follows: the pressure component (equivalent to the first force-applying component 7110) and the circumferential component (equivalent to the second force-applying component 7120) are moved down together by the lifting drive device (equivalent to the force-applying body 7130) until they move to the circumferential component circumferentially ...

[0131] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: The structure is simple; the assembly function of the equipment is realized through a single turntable, allowing for the switching assembly of two types of needle-free connectors on a single machine: a straight needle-free connector and a Y-type needle-free connector. Assembly can be completed without the use of ultrasonic welding, reducing the complexity of the mechanism and lowering costs. Furthermore, production efficiency is improved, with a capacity of 1800 pieces or more per hour. Simultaneously, the assembly qualification rate is improved even with insufficient material quality. The addition of springback detection raises the inspection standards for finished products and enhances the quality of the needle-free connectors.
