Next, a sealing plate installation mechanism installs the sealing plate. A defective product grabbing mechanism grabs defective products during the turntable's rotation. A material handling and flipping mechanism removes the assembled valve core body from the turntable and places it on a conveyor belt. The conveyor belt then transports the valve core body to a testing mechanism. A robotic grabbing mechanism places it into a sealing fixture. The pre-valve and post-valve valves control the airflow through the inlet and outlet pipes, working in conjunction with the sealing fixture to perform a sealing test on the valve core body. The entire process automates the assembly and testing process, reducing manual intervention and improving production efficiency.

[0020] This invention has at least the following beneficial effects:

[0021] 1. The bushing feeding mechanism delivers the bushing to the designated position on the turntable. The turntable rotates and brings it to the sealing ring installation mechanism. After the sealing ring is installed, it rotates to the valve core body installation mechanism to install the valve core body. Then, it goes to the sealing plate installation mechanism to install the sealing plate. The defective product grabbing mechanism grabs defective products during the turntable rotation. The material picking and flipping mechanism removes the assembled valve core body from the turntable and places it on conveyor belt one. Conveyor belt one conveys the valve core body to the inspection mechanism. The robot grabbing mechanism places it into the sealing fixture. The valve before and after the valve controls the airflow status of the air inlet and outlet pipes, and works with the sealing fixture to perform a sealing test on the valve core body. The entire process realizes automated operation from assembly to inspection, reduces manual intervention, and improves production efficiency. Through multi-step sealing inspection, the quality of the valve core body can be accurately judged, and defective products can be effectively screened out.

[0022] 2. During the testing process, cylinder one actuates first, driving multiple connected cylinders two to move up and down. Once cylinder two reaches the appropriate position, its output end aligns with the upper end of the valve core body. Next, cylinder two actuates further, pushing the rotating assembly into contact with the upper end of the valve core body. Then, the rotating assembly begins to operate, driving the valve core body to rotate within the sealing fixture. Through the coordinated action of cylinders one and two, the position and movement of the rotating assembly can be precisely controlled, ensuring accurate alignment with the valve core body and improving the accuracy and reliability of the test. Simultaneously, the rotating assembly drives the valve core body to rotate, allowing the sealing fixture to test the sealing performance of the valve core body at different angles and under different conditions, thus providing a more comprehensive evaluation of the valve core body's quality.

[0023] 3. During the inspection of the valve core body, the leak detector monitors the gas pressure inside the sealing fixture in real time. When a leak is detected in the valve core body and it is determined to be unqualified, the leak detector issues an alarm signal. At the same time, the relevant device will remove the defective product from the sealing fixture and place it in the defective product storage box for centralized storage. The leak detector can detect the leakage of the valve core body in real time and accurately, and issue an alarm in a timely manner, so that the operator can quickly know the test results.

[0046] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0047] like Figures 1-20As shown, the automatic valve core assembly and testing integrated production line provided in this embodiment includes an assembly mechanism 1 and a testing mechanism 2. The assembly mechanism 1 includes a platform 3 and a turntable 4. The platform 3 provides the basic support and installation platform for the entire assembly process. The turntable 4 carries and rotates the valve core body to be assembled, so that different assembly processes are performed sequentially. The turntable 4 is located at the center of the platform 3 and is rotatably connected to the platform 3. The turntable 4 can rotate freely on the platform. A bushing feeding mechanism 5 is fixedly connected to the upper surface of the platform 3 near the turntable 4. The bushing feeding mechanism 5 is responsible for conveying the bushing to the designated position on the turntable 4 to prepare for subsequent assembly. A sealing ring installation mechanism 6 is fixedly connected to the side of the turntable 4 near the bushing feeding mechanism 5. Structure 6 installs the outer and inner sealing rings on the outer wall and inside of the bushing, respectively, to achieve a sealing effect. The sealing ring installation mechanism 6 includes a rotary sealing ring mechanism 61 and an inner sealing ring installation assembly 62. The rotary sealing ring mechanism 61 is used to install the outer sealing ring in the corresponding position, and the inner sealing ring installation assembly is used to install the inner sealing ring in the corresponding position. The rotary sealing ring mechanism 61 includes a first adsorption column 63 and a rotary sealing ring oiling mechanism 64. The first adsorption column 63 is used to adsorb the outer sealing ring, facilitating its movement. The rotary sealing ring oiling mechanism 64 is used to apply grease to the outer sealing ring. The rotary sealing ring oiling mechanism 64 includes a first rotary motor 111, a first rotary box 112, and a first sealing ring. The upper surface of the platform 3 is fixedly connected to the fixed column 113 and the first rotary motor 111, supporting the first rotary motor 111. The first rotating box 112 is located above the first rotary motor 111. One end of the first sealing ring fixing column 113 passes through the first rotating box 112 and connects to the output end of the first rotary motor 111. It is fixed inside the first rotating box 112 to expand and fix the first sealing ring outward. The first rotary motor 111 drives the first sealing ring fixing column 113 to rotate. After the first sealing ring is fixed by the first sealing ring fixing column 113, the rotation of the first sealing ring fixing column 113 will drive the first sealing ring to rotate synchronously. The first clamping cylinder 11 is fixedly connected to the side of the platform 3 near the first rotary motor 111. 4. The output end of the first clamping cylinder 114 is connected to a first clamping claw 115. Under the control of the first clamping cylinder 114, the first clamping claw 115 can achieve contact with the first sealing ring when closed and open. The first clamping claw 115 has several oil seepage holes 116 on its inner wall surface in contact with the first sealing ring. The multiple oil seepage holes 116 facilitate the application of grease to the first sealing ring. When the first clamping claw 115 is closed, a limiting groove 117 is formed on the inner wall surface in contact with the first sealing ring to form an annular groove that surrounds and wraps around the first sealing ring. The limiting groove 117 helps to improve the uniformity of grease application to the first sealing ring. The first clamping claw 115 has an oil delivery channel 118 for connecting the oil seepage holes 116.The oil delivery channel 118 is connected to the oil storage tank, through which grease is transported to the oil delivery channel 118. The grease then flows evenly through the oil delivery channel 118 into multiple oil seepage holes 116.

[0048] Platform 133 has a bracket 134 near the first clamping cylinder 114. A sliding plate 135 is slidably connected to the bracket 134. A movable plate 136 is slidably connected to one side of the sliding plate 135. Multiple adsorption cylinders 137 are fixedly connected to one side of the movable plate 136. The output end of the adsorption cylinder 137 is connected to the first adsorption feeding column 119. A push cylinder 138 is fixedly connected to one side of the bracket 134. The output end of the push cylinder 138 is connected to one side of the sliding plate 135. A push cylinder 139 is fixedly connected to the upper end of the sliding plate 135. The output end of the push cylinder 139 is connected to the movable plate 136. When the push cylinder 138 is activated, its output end extends or retracts, pushing the sliding plate 135. 5. The sliding plate 135 slides horizontally on the support 134, causing the sliding plate 135 and its connected components, including the second pushing cylinder 139, the second moving plate 136, the adsorption cylinder 137, and the first adsorption loading column 119, to shift horizontally, thus adjusting its horizontal position to meet the operational requirements of different positions. When the second pushing cylinder 139 is activated, the extension and retraction of the output end pushes the second moving plate 136 to slide perpendicularly to the horizontal direction on the sliding plate 135. Since multiple adsorption cylinders 137 and the connected first adsorption loading column 119 are fixed on one side of the second moving plate 136, the sliding of the second moving plate 136 causes these components to adjust their positions in a direction perpendicular to the horizontal sliding plate 135. The adsorption position can be further precisely located. After the sliding plate 135 and the second moving plate 136 have completed their position adjustments, the adsorption cylinder 137 is activated, and the output end extends or retracts, driving the first adsorption feeding column 119 to perform an adsorption action. In this way, by pushing the first cylinder 138 and the second cylinder 139 to adjust the position, and in conjunction with the adsorption action of the adsorption cylinder 137, precise adsorption and gripping of materials at a specific position is achieved. The lower surface of the first adsorption feeding column 119 has adsorption air holes 120 from bottom to top for supplying air to adsorb the first sealing ring. After the first adsorption feeding column 119 adsorbs the first sealing ring, it can move it. The first adsorption feeding column 119 has several clearance notches 1 set along the circumferential direction from bottom to top. 21. The clearance notch 121 extends laterally from the outside to communicate with the adsorption vent 120. The lower half of the outer wall of the first sealing ring fixing column 8 is evenly provided with several clearance pieces 122 that are adapted to the clearance notch 121 along the circumferential direction. The clearance notch 121 and the clearance pieces 122 match, so that after the first adsorption feeding column 119 adsorbs the first sealing ring, the first sealing ring is placed on the outer wall of the first sealing ring fixing column 113, so that the first sealing ring fixing column 113 fixes the first sealing ring accordingly. The turntable 4 is provided with an optical fiber detection mechanism 123 on the side near the first adsorption feeding column 119. The optical fiber detection mechanism 123 is used to detect the outer wall of the bushing to determine whether the first sealing ring is installed on the outer wall of the bushing.

[0049] A valve core body mounting mechanism 7 is fixedly connected to the side of the turntable 4 near the sealing ring mounting mechanism 6. The valve core body mounting mechanism 7 will install the valve core body into the bushing. A sealing plate mounting mechanism 8 is fixedly connected to one side of the valve core body mounting mechanism 7. The sealing plate mounting mechanism 8 is responsible for installing the sealing plate onto the upper end of the valve core body. A defective product grabbing mechanism 9 is fixedly connected to the side of the turntable 4 near the sealing plate mounting mechanism 8. It grabs all defective products from the previous process from the turntable 4 to prevent them from flowing to the next process. A material picking and turning mechanism 10 is fixedly connected to the side of the platform 3 near the defective product grabbing mechanism 9. The material picking and turning mechanism 10 takes the assembled valve core body from the station of the turntable 4 and performs a turning operation. A conveyor belt 11 is fixedly connected to one side of the material picking and turning mechanism 10. The material picking and turning mechanism 10 places the assembled valve core body above the conveyor belt 11. The conveyor belt 11 conveys the assembled valve core body.

[0050] The testing mechanism 2 includes a platform 2 12 and multiple sets of closed testing components 13. The platform 2 12 supports multiple sets of closed testing components 13 and a conveyor belt 11. There are two sets of closed testing components 13, each including a pre-valve valve 14, a post-valve valve 15, and multiple sealing fixtures 16. The pre-valve valve 14 and post-valve valve 15 control the inlet and outlet of gas, and the sealing fixtures 16 are used to fix and seal the valve core body to be tested. The upper surface of the platform 2 12 is fixedly connected to one end of the conveyor belt 11, so that the conveyor belt 11 can transport the assembled valve core body to one side of the testing mechanism 2. The closed testing components 13 are located on one side of the conveyor belt 11, so that the closed testing components 13 can test the valve core body transported by the conveyor belt 11. An inlet pipe 17 and an outlet pipe 18 are respectively connected to one side of the sealing fixture 16. The inlet pipe 17 and the outlet pipe 18 transport... The gas is detected to form a cycle. One end of the inlet pipe 17 is connected to the pre-valve 14, and the ventilation state of the inlet pipe 17 is changed by the pre-valve 14. One end of the outlet pipe 18 is connected to the post-valve 15, and the ventilation state of the outlet pipe 18 is changed by the post-valve 15. When the valve core body is inside the sealing fixture 16, the valve core body is in the initial state, the pre-valve 14 is closed, and the post-valve 15 is opened, so that the gas enters the sealing fixture 16 through the inlet pipe 17 to perform a sealing test on the front end of the valve core body. If gas passes through the post-valve 15, the product can be determined to be a defective product, otherwise it is qualified. Then, after both the pre-valve 14 and the post-valve 15 are closed, the valve core body is rotated, and air is injected into the sealing fixture 16 through the inlet pipe 17. When the air pressure in the sealing fixture 16 decreases, the valve core body can be determined to be a defective product, otherwise it is a qualified product.

[0051] Furthermore, such as Figures 1-20As shown, the interior of the sealing fixture 16 is slidably connected to the valve core body, and the interior of the sealing fixture 16 is a sealed space, which facilitates the placement and removal of the valve core body inside the sealing fixture 16. The sealed space of the sealing fixture 16 facilitates the corresponding testing of the valve core body. A cylinder 21 is fixedly connected to the side of the platform 2 12 near the valve 15. Multiple cylinders 22 are fixedly connected to the output end of the cylinder 21. The cylinder 21 drives the multiple cylinders 22 to move up and down. There are four cylinders 22. The output end of the cylinders 22 is connected to a rotating component 23. The rotating component 23 is driven by the cylinders 22 to work. The interior of the rotating component 23 corresponds to the upper end of the valve core body. The rotating component 23 drives the valve core body to rotate inside the sealing fixture 16.

[0052] Among them, such as Figures 1-20 As shown, a leak detector 31 is fixedly connected to the side of platform 2 12 near cylinder 1 21. The leak detector 31 detects whether there is any leakage in the valve core body that passes through the sealing fixture 16. It judges whether the sealing performance of the valve core body is qualified by measuring parameters such as gas pressure and flow rate, and then triggers the corresponding alarm. A defective product storage box 32 is fixedly connected to the other side of the platform near cylinder 1 21. The defective product storage box 32 collects valve cores that are judged to be defective for subsequent processing or centralized management.

[0053] Furthermore, such as Figures 1-20 As shown, a robot gripping mechanism 41 is fixedly connected to one end of platform 2 12 near conveyor belt 11. The robot gripping mechanism 41 corresponds to conveyor belt 11 and multiple sealing fixtures 16 respectively. The robot gripping mechanism 41 grabs the assembled valve core from conveyor belt 11 and places it into the sealing fixture 16 for testing.

[0054] Furthermore, such as Figures 1-20 As shown, a second conveyor belt 51 is fixedly connected to the side of platform 2 12 near the first conveyor belt 11. One end of the second conveyor belt 51 extends directly below the robot gripping mechanism 41.

The laser engraving mechanism 52 engraves markings on the qualified valve cores. A finished product gripping mechanism 53 is fixedly connected to one side of the laser engraving mechanism 52. The finished product gripping mechanism 53 grips the finished valve cores with laser engraving and performs subsequent sorting or storage.

[0055] Among them, such as Figures 1-20As shown, the inner sealing ring installation assembly 62 includes a second adsorption column 71 and an inner sealing ring oiling mechanism 72. The inner sealing ring installation assembly 62 is responsible for the installation operation of the inner sealing ring. The second adsorption column 71 adsorbs the inner sealing ring for installation and moves it to the installation position. The output end of the inner sealing ring oiling mechanism 72 extends into the valve core body. The inner sealing ring oiling mechanism 72 applies grease to the inner sealing ring to improve installation and sealing performance. The inner sealing ring oiling mechanism 72 includes a rotating rod 124 and a pull rod assembly 73. A cylinder 126 is fixedly connected to the side of the platform 3 near the fiber optic detection mechanism 125. The output end of the cylinder 126 is fixedly connected to a moving rod assembly 73. The movable plate 127 and cylinder 126 provide power to drive the movable plate 127 to move. One side of the movable plate 127 is fixedly connected to the pull rod assembly 73. The movement of the movable plate 127 drives the pull rod assembly 73 to move. The rotating rod 124 passes through the movable plate 127 and is rotatably connected to the movable plate 127. The output end of the pull rod assembly 73 is fixedly connected to the push plate 128. The push plate 128 is sleeved on the outer wall of the rotating rod 124. Under the action of the pull rod assembly 73, the push plate 128 pushes the rotating rod 124 to move. The upper end of the rotating rod 124 is connected to the oil storage tank, and the grease in the oil storage tank is loaded into the rotating rod 124. The rotating rod 124 is used to transport grease. Rotating the rotating rod 124 spreads the grease evenly around the inner closed ring.

[0056] Among them, such as Figures 1-20 As shown, a valve stem mounting mechanism 129 is fixedly connected to the side of platform 3 near cylinder 126. The valve stem mounting mechanism 129 is responsible for feeding, gripping, and installing the valve stem. The valve stem mounting mechanism 129 includes a second feeding mechanism 130, a second cylinder 131, and a second gripping mechanism 132. The second feeding mechanism 130 is located on one side of the turntable 4 and is used to move the valve stem to one side of the turntable 4. The second feeding mechanism 130 transports the valve stem to a designated position on one side of the turntable 4, preparing for subsequent gripping and installation. Cylinder 131 is fixed to platform 3. The output end of cylinder 2 131 is connected to gripping mechanism 2 132. Cylinder 2 131 provides power to drive gripping mechanism 2 132 to perform actions. Gripping mechanism 2 132 corresponds to the valve stem. Gripping mechanism 2 132 grips the valve stem and installs it in the corresponding position. On the upper surface of platform 1 3 near cylinder 2 131, fiber optic detection mechanism 4 133 is fixedly connected. Fiber optic detection mechanism 4 133 detects the valve stem and its status and position to ensure that the valve stem meets the installation requirements.

[0057] Among them, such as Figures 1-20As shown, the sealing sheet installation mechanism 8 includes a sealing sheet feeding mechanism 81, a positioning mechanism 82, and a sealing sheet adsorption mechanism 83. The sealing sheet installation mechanism 8 is responsible for feeding, positioning, and installing the sealing sheets. The positioning mechanism 82 is located at the output end of the sealing sheet feeding mechanism 81. The sealing sheet feeding mechanism 81 continuously supplies sealing sheets, transporting them to the designated position to prepare for installation. The positioning mechanism 82 performs preliminary positioning on the sealing sheets output from the sealing sheet feeding mechanism 81 to ensure their approximate accuracy. The sealing sheet adsorption mechanism 83 uses adsorption force to grasp the sealing sheets and accurately position them. The sealing plate is installed onto the valve core body. The outer wall of the sealing plate adsorption mechanism 83 is connected to a pull rod mechanism 2 84. The pull rod mechanism 2 84 pulls or pushes the sealing plate adsorption mechanism 83 to change its position and angle. The other side of the sealing plate adsorption mechanism 83 is connected to a positioning mechanism 2 85. The positioning mechanism 2 85 positions the valve core body in the station on the turntable 4. The positioning mechanism 2 85 accurately positions the valve core body in the station on the turntable 4 to ensure that the sealing plate can be installed accurately. During the installation of the sealing plate, the position of the valve core body is fixed so that it corresponds to the sealing plate adsorption mechanism 83.

[0058] Among them, such as Figures 1-20 As shown, some fixed connections of the turntable 4 to the sealing plate installation mechanism 8 are made of pressure cylinder 91. The pressure cylinder 91 is located directly above the turntable 4 and corresponds to the sealing plate. The rotation of the turntable 4 moves the valve core body after the sealing plate is installed to below the pressure cylinder 91. The pressure cylinder 91 receives the signal and extends the piston rod downward to apply pressure to the sealing plate, ensuring that the sealing plate is installed firmly and tightly, and achieving the installation quality required by the process.

[0059] Among them, such as Figures 1-20 As shown, the defective product gripping mechanism 9 includes a slide rail 101, a defective product gripping claw 102, and a defective product storage box 103. The slide rail 101 and the defective product storage box 103 are both fixedly connected to the platform 3, and the defective product gripping claw 102 is slidably connected to the slide rail 101. The slide rail 101 provides a moving track for the defective product gripping claw 102 to ensure that it can move accurately and stably within a certain range. The defective product gripping claw 102 grips the valve core body that is detected as a defective product and transfers it from the turntable 4 to the defective product storage box 103. The defective product storage box 103 stores the defective valve core bodies transferred by the defective product gripping claw 102 for subsequent centralized processing.

[0060] like Figures 1-20As shown, the principle of the automatic valve core assembly and testing integrated production line provided in this embodiment is as follows: The bushing feeding mechanism 5 transports the bushing to the designated position of the turntable 4. The turntable 4 rotates, bringing the component with the bushing to the sealing ring installation mechanism 6. The rotary sealing ring mechanism 61 adsorbs the outer sealing ring through the first adsorption column 63. The rotary sealing ring oiling mechanism 64 applies grease to the outer sealing ring and then installs it. The inner sealing ring installation assembly 62 adsorbs the inner sealing ring through the second adsorption column 71 and then installs it. Then, the inner sealing ring oiling mechanism 72 applies grease to the installed inner sealing ring. The valve core body installation mechanism 7 then installs the valve core. The valve core body is installed onto the component with the sealing ring already installed. The sealing sheet feeding mechanism 81 conveys the sealing sheet, the positioning mechanism 82 performs initial positioning, and the sealing sheet adsorption mechanism 83 adsorbs the sealing sheet. With the cooperation of the pull rod mechanism 84 and the positioning mechanism 85, the sealing sheet is installed. The turntable 4 rotates, moving the valve core body after the sealing sheet is installed below the pressure cylinder 91. The pressure cylinder 91 applies pressure to the sealing sheet to ensure a secure installation. The turntable 4 continues to rotate. The defective product grabbing mechanism 9 detects defective products. The defective product grabbing claw 102 moves along the slide rail 101 to grab the defective product and place it into the defective product storage box 103. Qualified products arrive at the collection point. The material is removed from the material turning mechanism 10 and turned over, then placed on conveyor belt 11. The robot gripping mechanism 41 grips the product from conveyor belt 11 and places it into the sealing fixture 16. The pre-valve valve 14 is closed, and the post-valve valve 15 is opened. Gas enters the sealing fixture 16 to test the front end of the valve core body. When gas is discharged from the outlet pipe 18 to the post-valve valve 15, it can be determined that the valve core body is leaking, which is a defective product; otherwise, it is a qualified product. Then, the pre-valve valve 14 and the post-valve valve 15 are closed. The cylinder 21 drives multiple cylinders 22 to move downward, so that the rotating assembly 23 and the valve core body are aligned. Correspondingly at the upper end, cylinder 22 drives the rotating assembly 23 to rotate the valve core body, injecting gas into the sealed working chamber through the air inlet pipe 17 to perform a rear-end test on the valve core body. When the gas pressure inside the sealed working chamber decreases, a leak detector 31 is used for real-time monitoring to determine whether the valve core body is leaking. Products that fail the test are picked up by the robot gripping mechanism 41 and placed into the defective product storage box 32. Products that pass the test are transported by conveyor belt 51 to the laser engraving mechanism 52 for engraving and marking. The finished product gripping mechanism 53 picks up the engraved finished products for subsequent sorting and storage.
