[0043] See also Figure 2 and Figure 3 A waterproof breathable valve assembly line 10 includes: a feeding mechanism 11, a laser engraving mechanism 12, an inner grid assembly mechanism 13, a diaphragm assembly mechanism 14, a cover assembly mechanism 15, a sealing ring assembly mechanism 16 and a feeding mechanism 17, wherein a permeability detection mechanism 18 is arranged between the sealing ring assembly mechanism 16 and the feeding mechanism 17;
[0044] It should be noted that the waterproof breathable valve assembly line 10 is used to realize the automatic assembly of waterproof breathable valves. Figure 4 The valve bodies 21 are stacked in a tray 31. A feeding bin 33 and a discharging bin 34 are provided in the feeding mechanism 11. The tray 31 stacked with the valve bodies 21 is located in the feeding bin 33. The multi-axis manipulator 32 picks up the valve bodies 21 and transfers the valve bodies 21 to the laser engraving mechanism 12. The empty tray 31 is transported to the discharging bin 34 by the tray transporting manipulator 35.
[0045] See also Figure 5 The laser marking mechanism 12 is provided with an intermittent transport arm 41, a laser marker 42 and a vacuum suction pipe 43. The intermittent transport arm 41 moves the valve bodies 21 one by one into the working range of the laser marker 42, and the laser marker 42 marks the outer side of the valve body 21. At the same time, the vacuum suction pipe 43 draws air to absorb the dust generated during the marking process.
[0046] See also Figure 6The engraved valve body is fed into the inner grid assembly mechanism 13 to assemble the inner grid 23. The inner grid assembly mechanism 13 is provided with an inner grid feeding track 51, an inner grid assembly arm 52 and an ultrasonic welding machine 53. The inner grid 23 is transported along the inner grid feeding track 51. The inner grid assembly arm 52 picks up the inner grid 23 in the inner grid feeding track 51, loads it into the valve body 21, and welds the inner grid 23 and the valve body 21 together through the ultrasonic welding machine 53.
[0047] Next, see Figure 6 and Figure 7 The diaphragm 22 is laid in the valve body 21 by the diaphragm assembly mechanism 14. The diaphragm assembly mechanism 14 is provided with a film unwinding wheel group 61, a diaphragm separation table 62, a film coating robot 63, and an ultrasonic bonding device 64. The roll containing the diaphragm 22 is loaded in the film unwinding wheel group 61. After the release film of the roll is peeled off, the diaphragm 22 is temporarily placed on the diaphragm separation table 62. The film coating robot 63 picks up the diaphragm 22 and lays it in the valve body 21. The diaphragm 22 is bonded to the valve body 21 by the ultrasonic bonding device 64.
[0048] See also Figure 7 The cover body assembly mechanism 15 installs the valve cover on the valve body 21. The cover body assembly mechanism 15 is provided with a valve cover feeding track 71, a valve cover assembly robot 72 and a cap welder 73. The valve cover assembly robot 72 picks up the valve cover 25 in the valve cover feeding track 71, covers it on the valve body 21, and the cap welder 73 welds the two together.
[0049] Finally, the sealing ring assembly mechanism 16 binds the sealing ring on the outside of the valve body, that is, the waterproof breathable valve is assembled after passing through the sealing ring assembly mechanism 16, and the air permeability detection mechanism 18 performs air permeability detection on the waterproof breathable valve to eliminate defective products, and finally the unloading mechanism 17 takes away the qualified waterproof breathable valve.
[0050] See also Fig. 9 and Fig.10 The air permeability detection mechanism 18 includes a loading manipulator 100, a discharging manipulator 200 and at least two detection modules 300. Each detection module 300 includes a slide 310, a positioning seat 320, a pressing block 330 and an image collector 340. The positioning seat 320 is arranged on the top of the slide 310. The positioning seat 320 is provided with a storage cavity 321. The storage cavity 321 is used to accommodate the waterproof air permeable valve. The slide 310 is provided with a test pipe 311, and the test pipe 311 is connected to the storage cavity 321 (such as Figure 8 As shown in FIG. 3 ), the image collector 340 is disposed toward the positioning seat 320 .
[0051] Preferably, see Figure 8 and Fig.10A linear motor 350 is provided at the bottom of the slide 310. The linear motor 350 drives the slide 310 to translate between the loading robot 100 and the pressing block 330.
[0052] When performing air permeability testing, the slide 310 slides to the bottom of the pressing block 330 (such as Figure 8 As shown), at this time, the waterproof breathable valve in the positioning seat 320 enters the shooting range of the image collector 340, the pressing block 330 descends, and the waterproof breathable valve is tightly attached to the positioning seat 320, and the air permeability detection preparation is completed;
[0053] Next, the external gas source is started to introduce gas into the test pipe 311 to test whether the air permeability of the waterproof breathable valve meets the standard.
[0054] After the air permeability test is completed, the slide 310 and the pressing block 330 are reset, and the positioning seat 320 returns to the picking range of the manipulator, and the unloading manipulator 200 takes away the waterproof and breathable valve that has completed the test.
[0055] Among them, the positioning seat 320 is occupied during the air permeability detection process, and the next waterproof and breathable valve to be tested picked up by the loading robot 100 can only be placed in the positioning seat 320 of another detection module 300, that is, the detection module 300 receives the waterproof and breathable valve from the loading robot 100 in turn, which can avoid the waterproof and breathable valve to be tested being stranded due to standby during the air permeability detection.
[0056] Preferably, see Figure 8 and Fig.16 The opening side of the storage cavity 321 is provided with an annular rubber pad 322, and the inner diameter of the annular rubber pad 322 is consistent with the diameter of the storage cavity 321. When the pressing block 330 descends, the waterproof breathable valve is pressed on the annular rubber pad 322, and the annular rubber pad 322 cooperates with the sealing ring on the waterproof breathable valve to seal the storage cavity 321, so that the gas introduced into the test pipe 311 can only be discharged through the waterproof breathable valve, thereby improving the test accuracy.
[0057] A sealing pad 324 is provided at the position where the positioning seat 320 is connected to the slide 310. This improves the sealing performance of the position where the positioning seat 320 is connected to the slide 310, prevents gas leakage from the position where the positioning seat 320 is connected to the slide 310, and improves the accuracy of gas permeability detection.
[0058] In one embodiment, a positioning block 323 is provided on the positioning seat 320, and the positioning block 323 is arranged toward the opening of the storage cavity 321. The positioning block 323 contacts the outer wall of the waterproof breathable valve to be tested to prevent the waterproof breathable valve from rotating during the air permeability test. Preferably, the cross section of the contact position of the positioning block 323 and the waterproof breathable valve is in a "V" shape.
[0059] See also Fig. 9 and Fig.10The air permeability testing mechanism 18 also includes two transposition platforms 390, which are used to temporarily store waterproof breathable valves. The two transposition platforms 390 are respectively located at the starting end of the displacement of the loading robot 100 and the ending end of the displacement of the unloading robot 200, that is, the two transposition platforms 390 are respectively located at the feeding position and unloading position of the air permeability testing mechanism 18, serving as temporary storage points for loading and unloading waterproof breathable valves. Specifically, the placement point of the finished waterproof breathable valve assembled at the sealing ring assembly mechanism 16 when entering the air permeability testing mechanism 18 is the transposition platform 390 located at the starting end of the displacement of the loading robot 100, and the unloading robot 200 places the waterproof breathable valve that has completed the air permeability test on another transposition platform 390 to wait for sorting or unloading.
[0060] In one embodiment, please refer to Fig.10 The air permeability detection mechanism 18 also includes a discharging manipulator 370 and a discharging ladder 380. The discharging manipulator 370 includes a sorting claw 371 and a rotating arm 372. The sorting claw 371 is arranged toward the transposition platform 390, and the rotating arm 372 is used to drive the sorting claw 371 to flip toward the position of the discharging ladder 380. After the waterproof and breathable valve that does not meet the air permeability test is placed on the transposition platform 390, the sorting claw 371 clamps the defective product, and drives it to flip to the top of the discharging ladder 380 through the rotating arm 372, and the defective product is placed in the discharging ladder 380. The defective product slides down the discharging ladder 380 and leaves the air permeability detection mechanism 18. Preferably, the air permeability detection mechanism 18 also includes a defective product collection box, and the end of the discharging ladder 380 is arranged toward the defective product collection box. The defective product that slides down the discharging ladder 380 falls into the defective product collection box.
[0061] In summary, a permeability detection mechanism 18 is provided between the sealing ring assembly mechanism 16 and the unloading mechanism 17, the loading robot 100 places the waterproof breathable valve into the detection module 300 and the slide 310 performs an air permeability detection on it, and the image acquisition device 340 takes an image of the side of the waterproof breathable valve undergoing the air permeability detection, and detects it before unloading, so as to avoid unloading of defective products and ensure the delivery quality of the waterproof breathable valve.
[0062] In one embodiment, please refer to Fig. 9 and Fig.11, the sealing ring assembly mechanism 16 includes a valve body transfer robot 400, a guide rail 500, a positioning platform 600, a material picking robot 700, an extended air claw 800 and a lifting plate 900; the positioning platform 600 is located at the end of the guide rail 500; a avoidance hole 910 is opened at the center of the lifting plate 900, and the extended air claw 800 is penetrated by the avoidance hole 910; the material picking robot 700 is provided with a material picking rod, and the material picking rod is provided with an avoidance groove matching the extended air claw 800, the material picking robot 700 moves back and forth between the guide rail 500 and the lifting plate 900, and picks up the sealing ring from the positioning platform 600 and places it on the extended air claw 800, the extended air claw 800 is used to open the sealing ring, and the lifting plate 900 is used to push the opened sealing ring to move toward the end of the extended air claw 800; the valve body transfer robot 400 is used to drive the valve body to move back and forth between the transfer platform 390 and the lifting plate 900.
[0063] When the extended air claw 800 is not provided with a sealing ring, it is in a retracted state. The avoidance hole 910 provides a movable space for the extended air claw 800. When the extended air claw 800 is unfolded, the sealing ring can be stretched open so that the diameter of the sealing ring is larger than the diameter of the valve body. In this way, when the sealing ring is passed through the valve body, no axial force is generated on the sealing ring. The sealing ring is not in the avoidance area of the avoidance hole 910, that is, when the lifting plate 900 rises, it will contact the sealing ring and push the sealing ring to separate from the extended air claw 800, so that the sealing ring is sleeved in the groove of the valve body.
[0064] The valve body transfer manipulator 400 is used to drive the waterproof breathable valve to move back and forth between the transfer platform 390 and the lifting plate 900. When the valve body transfer manipulator 400 is started, the valve body on the transfer platform 390 can be transferred to the lifting plate 900, and after the sealing ring is assembled on the valve body, the waterproof breathable valve is put back on the transfer platform 390.
[0065] The working principle of the sealing ring assembly mechanism 16 is introduced below:
[0066] The material-retrieving robot 700 moves to the guide rail 500, picks up the sealing ring, and carries the sealing ring to the lifting plate 900. The material-retrieving robot 700 descends, and the air claw 800 is extended to penetrate the sealing ring;
[0067] The extended air claw 800 is unfolded to expand the sealing ring. At this time, the sealing ring is separated from the material picking robot 700, and the material picking robot 700 is reset. The sealing ring is transferred to the extended air claw 800 and is stretched open by the extended air claw 800. After the sealing ring is stretched open, the material picking robot 700 returns to the guide rail 500 to prepare to pick up the next sealing ring.
[0068] The valve body transfer manipulator 400 is started to move one of the valve bodies of the transfer platform 390 to the lifting plate 900. At this time, the waterproof breathable valve is located directly above the stretched sealing ring. The valve body transfer manipulator 400 descends to allow the valve body to pass through the sealing ring. During this process, the extended air claw 800 remains in an extended state. After the valve body transfer manipulator 400 descends into place, the groove on the valve body is located at the end of the extended air claw 800.
[0069] Next, the lifting plate 900 rises and pushes the unfolded sealing ring toward the end of the extended air gripper 800 until the sealing ring is separated from the extended air gripper 800. After the sealing ring is separated from the extended air gripper 800, it deforms and shrinks under its own elasticity, and then fits in the position of the groove, and the sealing ring is assembled;
[0070] The valve body transfer robot 400 drives the valve body to rise, and puts the valve body with the sealing ring back into the transfer platform 390; and when the valve body transfer robot 400 drives the valve body to rise, the extended air claw 800 switches from the expanded state to the retracted state, preparing for the assembly process of the next sealing ring.
[0071] In the above-mentioned sealing ring assembly process, the sealing ring's own elasticity is utilized and the sealing ring is enlarged by using an extended air claw 800 so that the sealing ring's diameter is larger than the diameter of the valve body, giving the valve body sufficient avoidance space. When the valve body penetrates the sealing ring, it does not contact the sealing ring, that is, no axial force is generated to push the sealing ring, thereby avoiding the sealing ring from shifting. It cooperates with the lifting plate 900 to put the sealing ring on the valve body, thereby ensuring the success rate of the sealing ring assembly and the automatic assembly of the sealing ring, thereby increasing the assembly efficiency of the sealing ring.
[0072] See also Fig.11 In this embodiment, the extended air gripper 800 includes a driver 810 and four movable claws 820. The four movable claws 820 are arranged in a circular array with the driver 810 as the center. The driver 810 is used to drive each movable claw 820 to approach or move away from the center of the driver 810. When the extended air gripper 800 is in a retracted state, the four movable claws 820 all move toward the center of the driver 810, and the distance between the four movable claws 820 is the smallest in this state; when the extended air gripper 800 is switched to an extended state, the movable claws 820 move in a direction away from the center of the driver 810, and the four movable claws 820 are separated from each other. In this state, the distance between the four movable claws 820 is the largest.
[0073] See also Fig.11 In one embodiment, the material picking robot 700 is provided with a material picking rod 710, and the diameter of the material picking rod 710 is larger than the sealing ring. In this way, after the material picking rod 710 passes through the sealing ring, the sealing ring can hold the outer wall of the material picking rod 710 to pick up the sealing ring.
[0074] See also Fig.12 and Fig.13Furthermore, the pick-up rod 710 is provided with a avoidance groove 711 matching the extended air claw 800, and the avoidance groove 711 is used to accommodate the extended air claw 800. In this way, when the pick-up manipulator 700 transfers the sealing ring to the extended air claw 800, the pick-up manipulator 700 drives the pick-up rod 710 to descend, and extends the extended air claw 800 into the avoidance groove 711, so that the extended air claw 800 in the contracted state passes through the sealing ring. After the extended air claw 800 is expanded, the stopper extends from the avoidance groove 711, and the sealing ring is stretched and separated from the pick-up rod 710. The elastic force generated by the deformation of the sealing ring acts on the extended air claw 800, thereby transferring the sealing ring and reducing the axial sliding distance of the sealing ring during the assembly process, which can prevent the sealing ring from separating from the extended air claw 800 and also prevent the sealing ring from being worn.
[0075] The sealing ring is stored in the vibration plate, and the sealing ring is sent into the guide rail 500 through the vibration plate. The straight vibrator drives the guide rail 500 to vibrate to drive the sealing ring to move toward the positioning platform 600. The positioning platform 600 is located at the end of the guide rail 500. The sealing ring stops moving forward after reaching the positioning platform 600, and the positioning platform 600 only accommodates one sealing ring. The positioning platform 600 is used as a position reference, and the material picking robot 700 picks up the sealing ring located in the positioning platform 600 when picking up materials.
[0076] It should be noted that when the material picking robot 700 picks up the sealing ring inside the positioning platform 600, the material picking rod 710 needs to penetrate the sealing ring, wherein the diameter of the material picking rod 710 is larger than the inner diameter of the sealing ring. When the material picking rod 710 penetrates the sealing ring, an axial impact force is applied to the sealing ring, which will cause the sealing ring to deform. When the sealing ring is deformed, elastic force is generated to cause it to jump out of the positioning platform 600 and detach from the positioning platform 600, resulting in material picking failure. That is, the material picking rod 710 has the problem of unstable material picking.
[0077] To solve the above problems, please refer to Fig.13 and Fig.14 The positioning platform 600 includes an adjustment frame 610, a block 620 and two anti-jumping baffles 630. The block 620 is arranged on the adjustment frame 610. A limiting groove 621 is provided on the side of the block 620 close to the guide rail 500. The limiting groove 621 is used to accommodate a sealing ring. The extension length of the limiting groove 621 is consistent with the outer diameter of the sealing ring; the limiting groove 621 is connected to the guide rail 500, and the sealing ring transmitted along the guide rail 500 directly enters the limiting groove 621. The first sealing ring is blocked by the groove wall of the limiting groove 621, and the blocked sealing ring is the target to be loaded.
[0078] The width of the anti-jumping baffle 630 is smaller than the width of the avoidance groove 711 on the material taking rod 710 , that is, the anti-jumping baffle 630 can penetrate the avoidance groove 711 .
[0079] The two anti-jumping baffles 630 are rotatably disposed on the baffle 620, and the two anti-jumping baffles 630 are distributed in a mirror image with the limiting groove 621 as the center;
[0080] See also Fig.14 and Fig.15 The stopper 620 is provided with a limiting step 622 and a blocking slope 623. The limiting step 622 is used to prevent the anti-jumping baffle 630 from rotating in the direction close to the limiting groove 621. In the initial state, the anti-jumping baffle 630 is flat on the limiting groove 621 and abuts against the limiting step 622. The limiting step 622 keeps the two anti-jumping baffles 630 flush (such as Fig.15 as shown).
[0081] The blocking slope 623 is used to prevent the anti-jumping baffle 630 from rotating in a direction away from the limiting groove 621, that is, after the anti-jumping baffle 630 rotates in a direction away from the limiting groove 621, it will abut against the blocking slope 623 (such as Fig.14 As shown), the rotation angle of the anti-jumping baffle 630 is limited by the blocking slope 623;
[0082] When the material picking robot 700 picks up the sealing ring, the working state of the anti-jump baffle 630 is as follows:
[0083] After the material-collecting robot 700 moves to the top of the stopper 620, two avoidance grooves 711 on the material-collecting rod 710 are aligned with the two anti-jumping baffles 630 on the stopper 620, and the material-collecting rod 710 starts to descend;
[0084] See also Fig.12 and Fig.15 When the material taking rod 710 contacts the sealing ring, an axial impact force is generated on the sealing ring. At this time, the two anti-jumping baffles 630 laid flat on the limiting groove 621 form a barrier to prevent the sealing ring from jumping out of the limiting groove 621, thereby ensuring that the material taking rod 710 can smoothly penetrate the sealing ring;
[0085] Since the diameter of the material taking rod 710 is larger than the sealing ring, when the material taking rod 710 passes through, the sealing ring is deformed and generates elastic force to wrap itself around the outer wall of the material taking rod 710;
[0086] See also Fig.13 and Fig.14 When the picking rod 710 rises, the sealing ring rises accordingly and pushes the two anti-jump baffles 630 to rotate in the direction away from the limiting groove 621. The distance between the ends of the two anti-jump baffles 630 increases accordingly until the sealing ring is out of the blocking range of the anti-jump baffles 630. The sealing ring moves with the picking rod 710 to the extended air claw 800 for assembly operation. After losing the support of the sealing ring, the two anti-jump baffles 630 reverse and are re-laid above the limiting groove 621.
[0087] In this way, when the material picking robot 700 performs the material picking operation, the two anti-jump baffles 630 cover the sealing ring to prevent it from escaping from the limiting groove 621, so that the sealing ring material picking process is stable and reliable.
[0088] See also Fig.14 Preferably, a magnet 631 is embedded in the anti-jumping baffle 630, and an iron gasket 622a matching the magnet 631 is arranged in the limiting step 622, so that when the anti-jumping baffle 630 and the limiting step 622 are in contact, the magnet 631 and the iron gasket 622a are attached, and the magnet 631 and the iron gasket 622a are adsorbed together, and the anti-jumping baffle 630 and the limiting step 622 are directly matched together through the magnetic attraction between the magnet 631 and the iron gasket 622a. The magnet 631 is a weak magnet 631, which only provides magnetic attraction to ensure that the anti-jumping baffle 630 will not be opened when the sealing ring jumps. The magnetic attraction provided by the magnet 631 is smaller than the friction between the sealing ring and the material picking rod 710, that is, when the material picking rod 710 rises, the sealing ring will not be scraped off by the anti-jumping baffle 630, further improving the stability of the sealing ring feeding process.
