Description

Technical Field

[0001] This invention relates to the field of side inlet valve processing equipment, and in particular to a fully automatic assembly line for toilet side inlet valve seats. Background Technology

[0002] like Figures 14-18 As shown, the side inlet valve includes a core 4, several sealing rings 5, a valve body 6, an inlet seat 7, a locking nut 8, and an inlet pipe 9. During the assembly process, sealing rings 5 ​​need to be fitted on the outer wall of the core 4 and the outer wall of the inlet seat 7.

[0003] Currently, the installation and assembly of the sealing ring 5, as well as the assembly of various components, are all done manually. This results in low work efficiency and high labor intensity. Furthermore, when manually pulling the sealing ring 5, it is difficult to control the force, which may break the sealing ring 5 and cause material waste. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a fully automated assembly line for toilet side inlet valve seats, which solves the problems of low work efficiency, high labor intensity, and difficulty in controlling the force when manually assembling sealing rings, which may break the sealing rings and cause material problems.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fully automatic assembly line for a toilet side inlet valve seat, wherein the side inlet valve seat includes a core, several sealing rings, a valve body, an inlet seat, a locking nut, and an inlet pipe; the outer surface of the core is provided with several first annular grooves from bottom to top; and the outer wall of the inlet seat is provided with a second annular groove; the fully automatic assembly line includes:

[0006] The first assembly machine includes a first support member and at least one second feeding mechanism. The first support member is provided with a core. Each second feeding mechanism includes a third driving member, a picking component, and a discharging component. The third driving member drives the picking component to grab and open the sealing ring and move it to be sleeved around the first annular groove of the core. The discharging component drives the sealing ring located on the picking component to detach from the picking component and move into the first annular groove of the core to form a valve core.

[0007] The second assembly machine includes a second support member, a first assembly structure, a second assembly structure, and a third assembly structure. The first assembly structure grips the valve body and engages it with the core body on which the sealing ring is assembled. The second assembly structure includes a third feeding mechanism with the same structure as the second feeding mechanism, which is used to grip and open the sealing ring and move it to be fitted into the second annular groove on the outer wall of the water inlet seat. The third assembly structure grips the water inlet seat on which the sealing ring is assembled and engages it with the valve body to form a barrel body.

[0008] The first transfer mechanism is used to transfer the valve core on the first support member to the second support member;

[0009] The third assembly includes a third support, a material handling mechanism, and a fourth feeding mechanism. The material handling mechanism includes a storage box and a guiding component. The bottom of the storage box has an outlet not smaller than the size of the water inlet pipe. The guiding component guides the water inlet pipes in the storage box out one by one from the outlet. The fourth feeding mechanism clamps and drives the water inlet pipes out from the outlet to move and engage with one side of the valve body.

[0010] The second transfer mechanism is used to transfer the barrel body on the second support to the third support.

[0011] Preferably, the material handling assembly includes a feeding component and at least one material handling component. Each material handling component includes a plurality of support rods arranged in a ring, with a first gap between each adjacent support rod. Each support rod has a vertical section and a bent section offset towards the center of the material handling component. The feeding component includes a plurality of first support plates arranged in a ring, with a sealing ring on the top of each first support plate. A second gap is provided between each adjacent first support plate. The third driving component drives each support rod to enter the second gap. The radius of the sealing ring when it is at its original length is smaller than the distance from the vertical section of the support rod to the center of the material handling component, and larger than the distance from the end of the bent section of the support rod away from the vertical section to the center of the material handling component.

[0012] Preferably, there are two material-picking components, including a first material-picking component and a second material-picking component. The radius of the vertical section of the second material-picking component is larger than the radius of the vertical section of the first material-picking component. The material-picking assembly also includes a transfer component, which includes a support base. The support base includes a plurality of second support plates arranged in a ring. There is a third gap between each of the second support plates. After the third driving component drives the first material-picking component to open and transfer the sealing ring to the second support plate, the third driving component drives the second material-picking component to open and transfer the sealing ring on the second support plate to the first annular groove.

[0013] Preferably, the second support plate has a bent portion and a vertical portion. The distance from the end of the bent portion away from the vertical portion to the center of the support seat is less than the radius of the original length of the sealing ring. The distance from the outer wall of the vertical portion to the center of the support seat is greater than the radius of the original length of the sealing ring. The radius of the second material taking member in the vertical section is greater than the distance between the outer wall of the vertical portion of the second support plate and the center point of the support seat.

[0014] Preferably, the first assembly machine further includes a plurality of first vibrating material trays containing sealing rings, the feeding component further includes a support platform, the support platform has a top groove, the top groove has a plurality of first support plates arranged in a ring, the support platform has a pushing component, the first vibrating material trays convey the sealing rings one by one to the support platform, and the pushing component conveys the sealing rings on the support platform to the first support plates in the top groove.

[0015] Preferably, the material guiding assembly includes a discharge roller rotatably disposed inside the storage box. The outer circumference of the discharge roller is provided with a plurality of grooves for accommodating water inlet pipes. At least one side of the storage box near the discharge port is provided with a guide plate. The guide plate is parallel to the central axis of the discharge roller. The distance between the outer wall of the discharge roller and the guide plate on the opposite side is less than the diameter of the water inlet pipe.

[0016] Preferably, the material handling mechanism further includes a temporary storage component, a transfer component, and a top material component. The temporary storage component is hollow inside, with openings at both its top and bottom ends. The transfer component transfers the water inlet pipes that are discharged from the discharge port to the area directly below the temporary storage component. The top material component guides the water inlet pipes on the transfer component into the temporary storage component through the bottom opening, and then discharges the water inlet pipes one by one from the top of the temporary storage component.

[0017] Preferably, the bottom of the temporary storage component is provided with a blocking component to block the water inlet pipe at the bottom of the temporary storage component. The blocking component includes two hooks hinged to both sides of the temporary storage component. A torsion spring is provided between the hooks and the temporary storage component. When the torsion spring is at its original length, the distance between the two hooks is less than the diameter of the water inlet pipe. During the process of the top material assembly guiding the water inlet pipe into the temporary storage component from the bottom opening, the torsion spring is in a compressed state.

[0018] Preferably, the third assembly machine further includes a detection and flipping mechanism, which includes a shooting unit and a clamping and flipping component, and the clamping and flipping component adjusts the angle and position of the water inlet pipe clamped by the fourth feeding mechanism.

[0019] Preferably, it also includes a locking nut mechanism, comprising a material picking and placing component and a tightening component, wherein the material picking and placing component grips the locking nut and sleeves it onto the water inlet seat.

[0020] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0021] This invention uses a second feeding mechanism to drive a material-grabbing component to grasp and expand the sealing ring, moving it to fit into the first annular groove of the core to form a valve core. Then, a first assembly structure grasps the valve body and fits it onto the periphery of the core with the assembled sealing ring. Next, a third feeding mechanism fits the sealing ring onto the outer wall of the water inlet seat. The third assembly structure then grasps the water inlet seat with the sealing ring and fits it onto the valve body to form the barrel body. Finally, a material guiding component guides the water inlet pipes from the storage tank out of the outlet one by one. A fourth feeding mechanism clamps and drives the water inlet pipes exiting from the outlet to fit onto one side of the valve body. This fully automated assembly line avoids the problems of low efficiency, high labor intensity, and difficulty in controlling force during traditional manual assembly of the sealing ring, which could break the sealing ring and waste materials. It also avoids the trouble of manually fitting the valve core and water inlet seat, and the water inlet pipe and valve body, reducing labor intensity and improving processing and assembly efficiency.

[0040] like Figures 1-18 As shown, the present invention provides a fully automatic assembly line for a toilet side inlet valve seat. The side inlet valve seat includes a core 4, several sealing rings 5, a valve body 6, an inlet seat 7, a locking nut 8, and an inlet pipe 9. The outer surface of the core 4 is provided with several first annular grooves 41 from bottom to top, and the outer wall of the inlet seat 7 is provided with a second annular groove. The fully automatic assembly line includes a first assembly machine 1, a second assembly machine 2, a first transfer mechanism, a third assembly machine 3, and a second transfer mechanism.

[0041] like Figures 2-5 As shown, the first assembly machine 1 includes a first support member 12 and at least one second feeding mechanism 15. The first support member 12 is provided with a core 4. Each second feeding mechanism 15 includes a third drive member 151, a picking component and a discharging component 156. The third drive member 151 (here, the third drive member 151 can be set as a three-axis robotic arm) drives the picking component to grab and open the sealing ring 5 and move it to fit around the first annular groove 41 of the core 4. The discharging component 156 drives the sealing ring 5 located on the picking component to detach from the picking component and move into the first annular groove 41 of the core 4 to form a valve core.

[0042] Here, we take four second feeding mechanisms 15 as an example for explanation. (The corresponding core 4 has four first annular grooves 41. Each second feeding mechanism 15 assembles a sealing ring 5 in the first annular groove 41 at a specific position on the core 4.) They are all located on one side of the long plate. By setting the first feeding mechanism 14 and multiple second feeding mechanisms 15, multiple cores 4 can be placed on the first support 12. When the first feeding mechanism 14 drives each core 4 to move on the long plate and pass through each second feeding mechanism 15 in sequence, each second feeding mechanism 15 can fit a sealing ring 5 in the first annular groove 41 on the outer wall of the core 4. Compared with one second feeding mechanism 15 fitting multiple sealing rings 5 ​​in sequence, the processing efficiency can be greatly improved.

[0043] It should be noted that, as Figure 14 As shown, when the size of the first annular groove 41 on the outer wall of the core 4 is not exactly the same, the size of the selected sealing ring 5 is also not exactly the same, and it can be adapted to each of the first annular grooves 41.

[0044] like Figures 6-9 As shown, the second assembly machine 2 includes a second support 22, a first assembly structure 23, a second assembly structure 24 and a third assembly structure 25. The first assembly structure 23 grips the valve body 6 and fits it into the outer periphery of the core 4 with the sealing ring 5 assembled. The second assembly structure 24 includes a third feeding mechanism 244 with the same structure as the second feeding mechanism 15, which is used to grip and open the sealing ring 5 and move it to fit into the second annular groove on the outer wall of the water inlet seat 7. The third assembly structure 25 grips the water inlet seat 7 with the sealing ring 5 assembled and fits it into the valve body 6 to form a barrel body.

[0045] It should be noted that while the valve body 6 and the core 4 are being clamped together by the first assembly structure 23, the sealing ring 5 on the outer wall of the water inlet seat 7 is being installed simultaneously, which improves work efficiency.

[0046] The first transfer mechanism is used to transfer the valve core on the first support member 12 to the second support member 22. The first transfer mechanism may include a first unloading transfer assembly 18 and / or a first conveyor belt. The two ends of the first conveyor belt are connected to the first support member 12 and the second support member 22. The first unloading transfer assembly 18 includes a fourth drive member (which can be a three-axis robotic arm) and a clamping structure (the specific working transfer principle is a conventional structure, which will not be described in detail here). Thus, the valve core can be directly transferred from the first support member 12 to the second support member 22 via the conveyor belt, or this action can be achieved through the first unloading transfer assembly 18.

[0047] like Figures 10-13As shown, the third assembly machine 3 includes a third support 32, a material picking mechanism 33 and a fourth feeding mechanism 37. The material picking mechanism 33 includes a storage box 331 and a material guiding component. The bottom of the storage box 331 has an outlet not smaller than the size of the water inlet pipe 9. The material guiding component guides the water inlet pipes 9 in the storage box 331 out one by one from the outlet. The fourth feeding mechanism 37 clamps and drives the water inlet pipes 9 out of the outlet to move and engage with one side of the valve body 6.

[0048] The second transfer mechanism is used to transfer the barrel body on the second support member 22 to the third support member 32. The working principle of the second transfer mechanism is the same as that of the first transfer mechanism, and will not be elaborated here.

[0049] like Figures 2-5 and Figure 14 As shown, during use, the core 4 is placed on the first support 12 (here, the core 4 can be automatically fed one by one by the second vibrating feeder 16, such as...). Figure 2 As shown), the third driving component 151 drives the material picking component to move, so that the material picking component grabs the sealing ring 5 and opens it (the material picking component can ensure that the size of the sealing ring 5 is the same each time it is opened, and the sealing ring 5 will not be broken) and moves it to the outer periphery of the first annular groove 41 of the core body 4. Then, through the action of the unloading component 156, it makes the sealing ring 5 on the material picking component detach from the material picking component and enter the first annular groove 41, thereby completing the automatic ringing of the sealing ring 5 in the first annular groove 41 on the outer wall of the core body 4 to form the valve core;

[0050] like Figures 6-9 as well as Figure 15 , Figure 16 As shown, the valve core is then transferred to the second support 22 by the first transfer mechanism, and then the valve body 6 is grabbed and snapped onto the outer periphery of the core 4 by the first assembly structure 23. At the same time, the assembly of the water inlet seat 7 is carried out simultaneously, that is, the third feeding mechanism 244 grabs and opens the sealing ring 5 and moves it into the second annular groove on the outer wall of the water inlet seat 7. Finally, the water inlet seat 7 is grabbed and snapped onto the valve body 6 by the third assembly structure 25 to form the barrel body.

[0051] like Figures 10-13 as well as Figure 18 As shown, the barrel body is then transferred to the third support member 32 by the second transfer mechanism. The water inlet pipes 9 in the storage box 331 are discharged one by one from the outlet by the material guide assembly. When each water inlet pipe 9 is discharged, the discharged water inlet pipe 9 can be clamped and fixed by the fourth feeding mechanism 37 and driven to move and engage with the valve body 6, thereby completing the automatic engagement and assembly of the valve body 6 and the water inlet pipe 9.

[0052] This fully automated assembly line avoids the problems of low efficiency, high labor intensity, and difficulty in controlling the force when manually assembling the sealing ring 5, which may break the sealing ring 5 and cause material waste. It also avoids the trouble of manually snapping together the valve core and the water inlet seat 7, and the water inlet pipe 9 and the valve body 6, thus reducing the labor intensity and improving the efficiency of processing and assembly.

[0053] like Figure 10 , Figure 13 and Figure 17 As shown, the fully automatic assembly line also includes a locking nut mechanism, including a material pick-and-place assembly 38 and a tightening assembly 36 (including a fifth clamping assembly and a motor that drives the fifth clamping assembly to rotate, and a three-axis manipulator that drives the fifth clamping assembly to move). The material pick-and-place assembly 38 picks up the locking nut 8 and sleeves it on the water inlet seat 7.

[0054] The feeding assembly 38 includes a sixth drive component 381 (which can be configured as a three-axis robot) and a fourth clamping component 382. It is connected to the third feeding channel 391 via the sixth vibrating feed plate 39, which can transport the locking nut 8 to the third feeding channel 391. The fourth clamping component 382 then clamps and grabs the locking nut 8 on the third feeding channel 391. The sixth drive component 381 then transports it through the water inlet seat 7. Finally, the tightening component 36 clamps and rotates the locking nut 8, so that the locking nut 8 locks and fixes the water inlet seat 7 and the valve body 6, further ensuring the stable connection between the water inlet seat 7 and the valve body 6, and avoiding the trouble of manually installing the locking nut 8 in the traditional way.

[0055] The first assembly machine 1 is provided with a first feeding mechanism 14, the second assembly machine 2 is provided with a fifth feeding mechanism 221, and the third assembly machine 3 is provided with a sixth feeding mechanism 321. The first support member 12, the second support member 22, and the third support member 32 can all be long plates. The fifth feeding mechanism 221 and the sixth feeding mechanism 321 can be provided with telescopic structures such as cylinders, which respectively push the valve core and the barrel body to move on the second support member 22 and the third support member 32.

[0056] like Figure 5 As shown, a long slit 121 is provided on the long plate of the first support member 12 along its length direction. Specifically, the first feeding mechanism 14 includes a first feeding assembly, which includes a first driving member 141 (including a first hydraulic rod that drives the insertion rod 143 to move horizontally and reciprocally along the length direction of the long plate and a second hydraulic rod that drives the insertion rod 143 to move up and down along the direction perpendicular to the long plate). The output end of the first driving member 141 is connected to the third support plate 142. Several insertion rods 143 are fixedly installed at equal intervals on the top surface of the third support plate 142. The first driving member 141 drives the insertion rods 143 to move through the long slit 121 into the core 4 and drive them to move along the length direction of the long plate.

[0057] The core 4 is hollow inside (this is the prior art). After the core 4 is placed on the long plate, by adjusting the first driving component 141, the second hydraulic rod first causes the insertion rod 143 to rise and pass through the long slot 121 into the core 4. Then, the first hydraulic rod drives the core 4 to move horizontally on the long plate, so that each core 4 can stably pass through each second feeding mechanism 15 one by one, thereby facilitating the stable installation of the sealing ring 5 in the first annular groove 41 at different positions on the core 4.

[0058] like Figure 5 As shown, the first feeding mechanism 14 further includes a second feeding assembly, which includes a second driving member 144. The output end of the second driving member 144 is connected to the fourth support plate 145. Several forks 146 are fixedly installed on one side of the fourth support plate 145. The second driving member 144 drives the forks 146 to move along the length direction perpendicular to the long plate. The forks 146 and the insert rod 143 move synchronously along the length direction of the long side.

[0059] The second driving component 144 here includes a third hydraulic rod that drives the shift fork 146 to reciprocate horizontally along the length of the long plate and a fourth hydraulic rod that drives the shift fork 146 to reciprocate horizontally along the direction perpendicular to the long plate. The third hydraulic rod and the first hydraulic rod can be set as a shared one, and the distance between the shift forks 146 is set to be equal to the distance between the insertion rods 143. By adjusting the fourth hydraulic rod, the shift fork 146 is moved to limit and clamp the core 4, further stabilizing the core 4 on the long plate for conveying, and further ensuring the stability of the outer surface of the core 4 for the application of the sealing ring 5.

[0060] It should be noted that when using the insertion rod 143, the first unloading and transfer assembly 18 must be used accordingly; the conveyor belt cannot be used alone.

[0061] In addition, when the first feeding and transfer component 18 grabs the valve core, it can be placed on the positioning seat 10 with the positioning rod 101, and then the positioning seat 10 can be transferred together to the second support member 22, thereby ensuring the stability of the valve core and the barrel body when they are transferred on the second support member 22 and the third support member 32 respectively.

[0062] like Figure 3 and Figure 4As shown, the material handling assembly includes a feeding component 154 and at least one material handling component. Each material handling component includes several support rods arranged in a ring. There is a first gap between each adjacent support rod. Each support rod has a vertical section and a bent section offset towards the center of the material handling component. The feeding component 154 includes several first support plates 1543 arranged in a ring. A sealing ring 5 is provided on the top of each first support plate 1543. There is a second gap between each adjacent first support plate 1543. A third driving component 151 drives each support rod to enter the second gap respectively. When the sealing ring 5 is at its original length, the radius is smaller than the distance from the vertical section of the support rod to the center of the material handling component, and larger than the distance from the end of the bent section of the support rod away from the vertical section to the center of the material handling component. This ensures that as the support rod is gradually inserted into the sealing ring 5, it can gradually open the sealing ring 5 and complete the material handling work.

[0063] The sealing ring 5 is placed on the first support plate 1543. The material picking component is driven to move by the third drive component 151, so that the bent sections of each support rod enter the interior of the sealing ring 5 and insert downward into the second gap. When the sealing ring 5 reaches the vertical section of the support rod, it is stretched to the maximum. At this time, the sealing ring 5 is stretched and thus stably fixed on the periphery of the material picking component, completing the automatic material picking of the sealing ring 5.

[0064] like Figure 3 and Figure 4 As shown, there are two material picking components, including a first material picking component 152 and a second material picking component 153. The radius of the vertical section of the second material picking component 153 is larger than the radius of the vertical section of the first material picking component 152. The material picking assembly also includes a transfer component 155. The transfer component 155 includes a housing and a support seat disposed in the housing. The support seat includes a plurality of second support plates arranged in a ring. There is a third gap between each second support plate. After the third driving component 151 drives the first material picking component 152 to open and transfer the sealing ring 5 to the second support plate, the third driving component 151 drives the second material picking component 153 to open and transfer the sealing ring 5 on the second support plate to the first annular groove 41.

[0065] By adjusting the third drive component 151, it drives the first material-taking component 152 to move and take material from the sealing ring 5 (that is, each support rod of the first material-taking component 152 is inserted into the second gap between each adjacent first support plate 1543), thereby completing the initial opening and material taking work of the sealing ring 5. Then, the third drive component 151 is adjusted to drive the first material-taking component 152 to move, so that each support rod of the first material-taking component 152 is inserted into the third gap between each second support plate, so that the sealing ring 5 is separated from the first material-taking component 152 and located on the second support plate.

[0066] Then adjust the third drive component 151 to drive the second material take-up component 153 to move, so that each support rod of the second material take-up component 153 is inserted into the third gap, thereby causing the sealing ring 5 to disengage from the second support plate and be located on the second material take-up component 153.

[0067] By repeatedly expanding the sealing ring 5 and gradually increasing its size, the sealing ring 5 can be prevented from being expanded too much at once, which could cause it to break.

[0068] The specific unloading component 156 includes a fifth driving member and an unloading plate (preferably a cylinder). The unloading plate is closely attached to the outer wall of the vertical section of the second material taking member 153. The fifth driving member drives the unloading plate to move up and down along the outer wall of the vertical section of the second material taking member 153. This allows the unloading plate to move down along the outer wall of the vertical section of the second material taking member 153 by adjusting the fifth driving member, thereby completing the automatic unloading of the sealing ring 5 on the second material taking member 153 and allowing it to enter the first annular groove 41 of the core 4.

[0069] like Figure 3 As shown, the second support plate has a bent part and a vertical part. The distance from the end of the bent part away from the vertical part to the center of the support seat is less than the radius of the original length of the sealing ring 5. The distance from the outer wall of the vertical part to the center of the support seat is greater than the radius of the original length of the sealing ring 5. The radius of the second material taking part 153 in the vertical section is greater than the distance between the outer wall of the vertical part of the second support plate and the center point of the support seat.

[0070] Specifically, the support base here can be designed to resemble a bullet shape, so that after the sealing ring 5 is conveyed to the vertical part of the second support plate by the first material picker 152, the support rod of the first material picker 152 will no longer be in contact with the sealing ring 5. Subsequently, the second material picker 153 will be moved by adjusting the third drive member 151 to open up the sealing ring 5 on the second support plate and pick it up, so that it will be separated from the second support plate.

[0071] like Figures 2-4 As shown, the first assembly machine 1 also includes several first vibrating material trays 13 that contain sealing rings 5, and the feeding component 154 also includes a support platform 1541. The support platform 1541 has a top groove, and several first support plates 1543 arranged in a ring are provided in the top groove. The support platform 1541 is provided with a pushing component 1542 (including a cylinder and a push plate, and a notch is provided on the push plate). The first vibrating material trays 13 convey the sealing rings 5 ​​one by one to the support platform 1541, and the pushing component 1542 conveys the sealing rings 5 ​​on the support platform 1541 to the first support plates 1543 in the top groove.

[0072] The sealing rings 5 ​​are automatically conveyed one by one to the designated position on the support table 1541 by the first vibrating feeder 13. Figure 4At the notch on the push plate shown, the push plate is moved by the cylinder to the first support plate 1543 in the top groove, so that the material picking component can be moved to a fixed point to pick up the material by adjusting the third drive component 151.

[0073] like Figure 2 As shown, the first assembly machine 1 also includes a detection component 17 located on one side of the long plate. The detection component 17 includes a fifth support plate. Several sensing units are arranged from top to bottom on one side of the fifth support plate. Each sensing unit (which may be a photoelectric sensor) detects a sealing ring 5.

[0074] After the sealing rings 5 ​​are automatically installed in all the first annular grooves 41 opened on the outer wall of the core 4, the first feeding mechanism 14 drives the core 4 to move on the first support member 12 until it reaches the detection component 17, and the sensing unit detects whether the sealing rings 5 ​​are installed in the first annular grooves 41 on the outer wall of the core 4.

[0075] like Figure 2 As shown, the first assembly machine 1 also includes a second vibrating feeder 16, which is used to automatically feed and transport the core 4 of the sealing ring 5 to be assembled to the first support member 12.

[0076] like Figure 6 As shown, the second assembly machine 2 also includes a third vibrating material plate 246 (whose discharge end is connected to the fourth feeding channel for automatically conveying the sealing ring 5, so as to facilitate the assembly of the sealing ring 5 onto the outer wall of the water inlet seat 7), a fourth vibrating material plate 248 (whose discharge end is connected to the first feeding channel 2481 for automatically conveying the water inlet seat 7, so as to facilitate the automatic feeding of the subsequent second assembly structure 24), and a fifth vibrating material plate 26 (whose discharge end is connected to the second feeding channel 261 for automatically conveying the valve body 6, so as to facilitate the subsequent first assembly structure 23 to grab the valve body 6 and assemble it with the core 4).

[0077] like Figure 6 , Figure 8 and Figure 9 As shown, the second assembly structure 24 also includes a turntable 242, a first feeding mechanism 241, a third feeding mechanism 244 and a fourth vibrating material plate 248. The discharge end of the fourth vibrating material plate 248 is connected to the first feeding channel 2481. The turntable 242 is provided with a plurality of receiving seats 243 supporting the water inlet seat 7. The first feeding mechanism 241 is used to grab the water inlet seat 7 and place it in the receiving seat 243. The receiving seats 243 on the turntable 242 pass through the first feeding mechanism 241 and the third feeding mechanism 244 one by one.

[0078] The first feeding mechanism 241 includes a first three-axis drive arm and a first clamping assembly. After the first clamping assembly clamps and fixes the water inlet seat 7 on the first feeding channel 2481, the first three-axis drive arm drives the first clamping assembly to transfer the water inlet seat 7 into the receiving seat 243. The drive turntable 242 rotates (by a motor), thereby moving the receiving seat 243 to the third feeding mechanism 244. The third feeding mechanism 244 performs the sealing ring 5 on the water inlet seat 7. Then the turntable 242 continues to rotate, causing the water inlet seat 7 with the sealing ring 5 assembled to move to the third assembly structure 25 (including a second three-axis drive arm and a second clamping assembly). The second clamping assembly clamps and fixes the water inlet seat 7. Finally, the second three-axis drive arm drives the second clamping assembly to move, so that it grabs the water inlet seat 7 and moves it to engage with the valve body 6, thereby completing the automatic assembly of the core 4 and the valve body 6, as well as the valve body 6 and the water inlet seat 7.

[0079] In addition, before the water inlet seat 7 reaches the third assembly structure 25 after passing the third feeding mechanism 244, it will be detected by the first detection unit 245 (which may be a photoelectric sensor) to detect whether each water inlet seat 7 is equipped with a sealing ring 5.

[0080] like Figure 9 As shown, the second assembly structure 24 also includes a flipping clamping mechanism 247 (including a motor and a third clamping assembly) for adjusting the angle position of the water inlet seat 7;

[0081] After the water inlet seat 7 with the sealing ring 5 installed is clamped and removed by the third assembly structure 25, it is then clamped and fixed by the third clamping component. The third clamping component is rotated 180 degrees by the motor, and finally the water inlet seat 7 on the third clamping component is removed by the third assembly structure 25 so that it is engaged with the valve body 6.

[0082] like Figure 1 , Figure 6 and Figure 7 As shown, the automatic assembly equipment also includes a fifth vibrating material tray 26. The discharge end of the fifth vibrating material tray 26 is connected to a second feeding channel 261. A second detection unit 27 (which can be a photoelectric sensor) is provided on one side of the second feeding channel 261. The valve body 6 is cross-shaped. The first assembly structure 23 includes a seventh driving component (which can be a three-axis robotic arm), a rotating component, and a clamping component. The seventh driving component and the rotating component adjust the position and angle of the valve body 6.

[0083] The valve body 6 has an asymmetrical structure. When the valve body 6 is on the second feeding channel 261, the orientation of each valve body 6 may be inconsistent. The second detection unit 27 detects that when the orientation of a valve body 6 is inconsistent, the valve body 6 is clamped and fixed by the clamping member, and then rotated by the rotating member. Thus, the seventh driving member drives the valve body 6 to move, ensuring that the orientation of each valve body 6 is consistent and installed on the periphery of the core 4.

[0084] like Figure 12 As shown, the material guiding assembly includes a discharge roller 332 rotatably disposed inside the storage box 331. The outer circumference of the discharge roller 332 is provided with a plurality of grooves 3321 for accommodating water inlet pipes 9 (each groove 3321 can only accommodate one water inlet pipe 9). At least one of the two sides near the discharge port inside the storage box 331 is provided with a guide plate. The guide plate is parallel to the central axis of the discharge roller 332. The distance between the outer wall of the discharge roller 332 and the guide plate on the opposite side is less than the diameter of the water inlet pipe 9.

[0085] This ensures that the water inlet pipe 9 remains stable between the discharge roller 332 and the guide plate, and does not detach from the groove 3321. When the water inlet pipe 9 moves to the discharge port, the guide plate no longer restricts it, and the water inlet pipe 9 detaches from the groove 3321 and falls from the discharge port, thus completing the individual material handling of the water inlet pipe 9.

[0086] Specifically, the guide plate here is arc-shaped, and guide plates are provided on both sides of the storage box 331 near the discharge port. In this way, no matter whether the discharge roller 332 rotates clockwise or counterclockwise, the water inlet pipe 9 can be separated from the groove 3321 and finally discharged from the discharge port.

[0087] like Figure 12 As shown, the material handling mechanism 33 also includes a temporary storage component 335, a transfer component (including an eighth drive component 333 and a collection component 334, the length of the collection component 334 is less than the length of the water inlet pipe 9, so that the subsequent top material component 337 can push the water inlet pipe 9 out of the collection component 334) and a top material component 337. The temporary storage component 335 is hollow inside, and its top and bottom ends are provided with openings. The transfer component transfers the water inlet pipe 9 that is discharged from the discharge port to the area directly below the temporary storage component 335. The top material component 337 (including a ninth drive component 3371 and a top rod 3372) guides the water inlet pipe 9 on the transfer component into the temporary storage component 335 through the bottom opening of the temporary storage component 335, and discharges the water inlet pipe 9 one by one from the top of the temporary storage component 335.

[0088] like Figure 12 As shown, the bottom of the temporary storage component 335 is provided with a blocking component 336 to block the water inlet pipe 9 at the bottom of the temporary storage component 335, preventing the water inlet pipe 9 inside the temporary storage component 335 from being discharged from the bottom opening of the temporary storage component 335 and detached from the temporary storage component 335.

[0089] The blocking member 336 includes two hooks hinged to both sides of the temporary storage member 335. A torsion spring (not shown in the figure) is provided between the hooks and the temporary storage member 335. When the torsion spring is at its original length, the distance between the two hooks is less than the diameter of the water inlet pipe 9, thereby ensuring that the two hooks block the water inlet pipe 9 inside the temporary storage member 335. During the process of the top material assembly 337 guiding the water inlet pipe 9 into the temporary storage member 335 from the bottom opening of the temporary storage member 335, the torsion spring is in a compressed state, thereby facilitating the water inlet pipe 9 to enter the temporary storage member 335 through the hooks and the bottom opening of the temporary storage member 335.

[0090] like Figure 11 As shown, the fourth feeding mechanism 37 includes a tenth driving member 371, a seventh clamping assembly, an eleventh driving member 372, and a feeding channel 373. The tenth driving member 371 drives the seventh clamping assembly to move and clamp and fix the water inlet pipe 9 that is led out from the top of the temporary storage member 335 and transport it to the feeding channel 373. The eleventh driving member 372 drives the water inlet pipe 9 to move along the feeding channel 373 and engage with the valve body 6.

[0091] The tenth drive unit 371 here includes a first hydraulic rod and a second hydraulic rod (or a first cylinder and a second cylinder) that drive the seventh clamping assembly to move horizontally and vertically along the feed channel 373.

[0092] Alternatively, the fourth feeding mechanism 37 can be configured as a three-axis robotic arm (replacing the tenth drive component 371 and the eleventh drive component 372) and a seventh clamping assembly, thus eliminating the need for the feeding channel 373. However, the assembly efficiency of this method is relatively slower than that of using the tenth drive component 371 and the eleventh drive component 372. With the tenth drive component 371 and the eleventh drive component 372, the two can work simultaneously. Thus, while the eleventh drive component 372 drives the water inlet pipe 9 to move and assemble it onto the valve body 6, the tenth drive component 371 can simultaneously drive the seventh clamping assembly to perform the clamping work on the next water inlet pipe 9, thereby improving processing efficiency.

[0093] The third assembly machine 3 also includes a detection and flipping mechanism 31, which includes a shooting unit 310 and a clamping and flipping component 311. The clamping and flipping component 311 adjusts the angle position of the water inlet pipe 9 clamped by the fourth feeding mechanism 37.

[0094] The shooting unit 310 and the clamping and flipping assembly 311 are positioned opposite each other. The water inlet pipe 9 is not a perfectly regular circle; it has two long slots symmetrically opened on its side (this is the existing structure of the water inlet pipe 9). After the fourth feeding mechanism 37 grabs the water inlet pipe 9 from the top of the temporary storage component 335, it is first transported between the shooting unit 310 and the clamping and flipping assembly 311. The shooting unit 310 takes pictures of the water inlet pipe 9, and then the sixth clamping assembly clamps and fixes the water inlet pipe 9. Finally, the motor drives the sixth clamping assembly to rotate, thereby completing the adjustment of the angle position of the water inlet pipe 9. After the adjustment is completed, the seventh clamping assembly of the fourth feeding mechanism 37 clamps the material again, and finally the tenth driving component 371 transports it to the feeding channel 373, ensuring that each water inlet pipe 9 on the feeding channel 373 is placed at a uniform angle (the two long slots are located directly above and below the water inlet pipe 9, respectively), ensuring that the subsequent assembly work proceeds smoothly.

[0095] like Figure 11 As shown, it also includes a fixing mechanism 35 to further fix the valve body 6 on the third support member 32 that needs to be connected to the water inlet pipe 9;

[0096] The fixing mechanism 35 includes a cylinder and a pressure block. The cylinder drives the pressure block to move, so that it presses against the top of the valve body 6, thereby fixing it to the third support member 32 and ensuring the stability of the water inlet pipe 9 and the valve body 6.

[0097] like Figure 10 As shown, the automatic assembly equipment also includes a feeding mechanism 34, which is used to remove the assembled valve body 6 and water inlet pipe 9 from the third support member 32 to complete the automatic feeding operation.
