The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0039] See also Figure 2 and Figure 3 The present invention provides an O-ring automatic assembly mechanism 10 for a waterproof breathable valve, comprising: a turntable 100, a valve body transfer manipulator 200, a direct vibration track 300, a material taking manipulator 400 and an assembly platform 500.

[0040] See also Figure 3 and Figure 4 The assembly platform 500 is provided with an extended air gripper 510 and a lifting plate 520. A avoidance hole 511 is opened at the center of the lifting plate 520, and the extended air gripper 510 is penetrated with the avoidance hole 511; the material-retrieving manipulator 400 moves back and forth between the straight vibration track 300 and the assembly platform 500, and picks up the O-ring 22 from the straight vibration track 300 and places it on the extended air gripper 510. The extended air gripper 510 is used to open the O-ring 22, and the lifting plate 520 is used to push the opened O-ring 22 to move toward the end of the extended air gripper 510;

[0041] The extended air claw 510 is in a retracted state when the O-ring 22 is sleeved, and the avoidance hole 511 provides a movable space for the extended air claw 510. When the extended air claw 510 is unfolded, the O-ring 22 can be stretched open, so that the diameter of the O-ring 22 is larger than the diameter of the valve body 21. In this way, when the O-ring 22 is passed through the valve body 21, no axial force is generated on the O-ring 22, wherein the O-ring 22 is not in the avoidance area of ​​the avoidance hole 511, that is, when the lifting plate 520 rises, it will contact the O-ring 22 and push the O-ring 22 out of the extended air claw 510, so that the O-ring 22 is sleeved in the groove 23 of the valve body 21.

[0042] See also Figure 2 The turntable 100 is provided with a plurality of jigs 110, which are used to store the valve bodies 21. The turntable 100 drives the plurality of valve bodies 21 stored in the jigs 110 to rotate intermittently, so that the valve bodies 21 are sequentially moved into the picking range of the valve body transfer robot 200. The turntable 100 includes a stationary table 120 and a rotating table 130, and the jigs 110 are located on the rotating table 130. When the turntable 100 is started, the stationary table 120 does not move, and the rotating table 130 rotates.

[0043] The valve body transfer robot 200 is used to drive the valve body 22 to move back and forth between the turntable 100 and the assembly platform 500. The valve body transfer robot 200 is arranged on the stationary table 120. When the valve body transfer robot 200 is started, the valve body 21 on the turntable 100 can be transferred to the assembly platform 500, and after the O-ring 22 is assembled on the valve body 21, the valve body 21 is put back into the turntable 100.

[0044] The working principle of the above-mentioned O-ring automatic assembly mechanism 10 for waterproof breathable valve is introduced below:

[0045] The material-retrieving manipulator 400 moves to the vertical vibration track 300, picks up the O-ring 22, and carries the O-ring 22 to the assembly platform 500. The material-retrieving manipulator 400 descends, and the air claw 510 is extended to penetrate the O-ring 22.

[0046] The expansion air claw 510 is unfolded to expand the O-ring 22. At this time, the O-ring 22 is separated from the material picking robot 400. The material picking robot 400 is reset, and the O-ring 22 is transferred to the expansion air claw 510 and is expanded by the expansion air claw 510. After the O-ring 22 is expanded, the material picking robot 400 returns to the straight vibration track 300 to prepare to pick up the next O-ring 22.

[0047] The valve body transfer robot 200 is started, and one of the valve bodies 21 of the turntable 100 is moved to the assembly platform 500. At this time, the valve body 21 is located directly above the stretched O-ring 22. The valve body transfer robot 200 descends, and the valve body 21 passes through the O-ring 22. During this process, the extended air claw 510 remains in the extended state. After the valve body transfer robot 200 descends into place, the groove 23 on the valve body 21 is located at the end of the extended air claw 510.

[0048] Next, the lifting plate 520 rises and pushes the unfolded O-ring 22 to move toward the end of the extended air gripper 510 until the O-ring 22 is separated from the extended air gripper 510. After the O-ring 22 is separated from the extended air gripper 510, it deforms and shrinks under its own elasticity, and then fits in the position of the groove 23, and the O-ring 22 is assembled;

[0049] The valve body transfer robot 200 drives the valve body 21 to rise, and puts the valve body 21 with the O-ring 22 back into the turntable 100; and when the valve body transfer robot 200 drives the valve body 21 to rise, the extended air claw 510 switches from the expanded state to the retracted state, preparing for the next O-ring 22 assembly process.

[0050] In the above-mentioned O-ring 22 assembly process, the elasticity of the O-ring 22 itself is utilized, and the extended air claw 510 is used to expand the O-ring 22, so that the diameter of the O-ring 22 is larger than the diameter of the valve body 21, giving the valve body 21 enough avoidance space. When the valve body 21 penetrates the O-ring 22, it does not contact the O-ring 22, that is, no axial force is generated to push the O-ring 22, which can avoid the displacement of the O-ring 22. It cooperates with the lifting plate 520 to put the O-ring 22 on the valve body 21, thereby ensuring the success rate of the O-ring 22 assembly, the automatic assembly of the O-ring 22, and the improvement of the assembly efficiency of the O-ring 22.

[0051] See also Figure 4 and Fig.10In this embodiment, the extended air gripper 510 includes a driver 512 and four movable claws 513. The four movable claws 513 are arranged in a circular array with the driver 512 at the center. The driver 512 is used to drive each movable claw 513 to approach or move away from the center of the driver 512. When the extended air gripper 510 is in a retracted state, the four movable claws 513 all move toward the center of the driver 512, and the distance between the four movable claws 513 is the smallest in this state; when the extended air gripper 510 switches to an extended state, the movable claws 513 move in a direction away from the center of the driver 512, and the four movable claws 513 separate from each other. In this state, the distance between the four movable claws 513 is the largest.

[0052] See also Fig.10 Preferably, the movable claw 513 is provided with a stopper 513a and a guide part 513b, the stopper 513a is used to contact the O-ring 22, the stopper 513a is located at the end of the guide part 513b, the guide part 513b is connected to the driver 512, and the thickness of the guide part 513b decreases from the end connected to the driver 512 toward the side where the stopper 513a is located, that is, the cross section of the guide part 513b is trapezoidal, which can guide the O-ring 22 into the stopper 513 a, prevent the O-ring 22 from staying in the guide portion 513b. Even if the material-retrieving robot 400 transfers the O-ring 22 to the extended air gripper 510, it brings the O-ring 22 to the guide portion 513b. When the extended air gripper 510 is switched to the expanded state, the movable claw 513 applies a radial force to the O-ring 22, which will generate an axial component force, causing the O-ring 22 to be scratched into the stop portion 513a, so as to ensure that the O-ring 22 is in a predetermined position after the extended air gripper 510 is expanded.

[0053] See also Figure 4 and Fig.10 The avoidance hole 511 includes a central cavity 511a and a plurality of branches 511b. When the extended air gripper 510 is in a retracted state, each movable claw 513 is located in the central cavity 511a; when the extended air gripper 510 is switched to an extended state, the movable claw 513 moves from the central cavity 511a to the corresponding branch 511b.

[0054] See also Figure 4 Specifically, the assembly platform 500 is provided with a bearing bracket 530, a lifting cylinder 540, an adapter plate 550 and a guide rod 560. The lifting cylinder 540 and the extended claw 510 are both arranged on the bearing bracket 530. The adapter plate 550 is installed on the output end of the lifting cylinder 540. The two ends of the guide rod 560 are respectively connected to the adapter plate 550 and the lifting plate 520. The bearing bracket 530 is located at the edge of the turntable 100. When the lifting cylinder 540 is started, the adapter plate 550 is pushed up and down, and the lifting plate 520 is driven to move together through the guide rod 560, thereby realizing long-distance transmission.

[0055] See also Figure 3 In one embodiment, the picking robot 400 is provided with a picking rod 410 , and the diameter of the picking rod 410 is larger than the O-ring 22 . Thus, after the picking rod 410 passes through the O-ring 22 , the O-ring 22 can hold the outer wall of the picking rod 410 , thereby picking up the O-ring 22 .

[0056] See also Figure 4 and Figure 5 Furthermore, the pick-up rod 410 is provided with a avoidance groove 411 matching with the movable claw 513, and the avoidance groove 411 is used to accommodate the movable claw 513. In this way, when the pick-up manipulator 400 transfers the O-ring 22 to the extended air claw 510, the pick-up manipulator 400 drives the pick-up rod 410 to descend, and makes the movable claw 513 on the extended air claw 510 extend into the avoidance groove 411, so that the stopper 513a of the movable claw 513 passes over the O-ring 22. After the extended air claw 510 is unfolded, the stopper 513a extends from the avoidance groove 411 and stretches the O-ring 22. The elastic force generated by the deformation of the O-ring 22 acts on the movable claw 513, thereby transferring the O-ring 22 and reducing the axial sliding distance of the O-ring 22 during the assembly process, which can prevent the O-ring 22 from detaching from the extended air claw 510 and also prevent the O-ring 22 from being worn.

[0057] See also Figure 4 Specifically, the material picking robot 400 is provided with a transverse cylinder 420 and a longitudinal cylinder 430. The longitudinal cylinder 430 is arranged at the output end of the transverse cylinder 420. The transverse cylinder 420 is used to drive the material picking rod 410 to move back and forth between the assembly platform 500 and the vertical vibration track 300, and the longitudinal cylinder 430 is used to drive the material picking rod 410 to rise or fall. When the material picking robot 400 moves to the straight vibration track 300 to pick up materials, the transverse cylinder 420 drives the material picking rod 410 to translate between the assembly platform 500 and the straight vibration track 300, so that the material picking rod 410 moves to above the extended air claw 510 and the straight vibration track 300; the longitudinal cylinder 430 is used to drive the material picking rod 410 to rise or fall, for example: when the transverse cylinder 420 moves the material picking rod 410 to above the straight vibration track 300, the longitudinal cylinder 430 is started, the material picking rod 410 descends and passes through an O-ring 22 in the straight vibration track 300, and when the longitudinal cylinder 430 is reset, it drives the material picking rod 410 to rise and take out the O-ring 22.

[0058] See also Figure 3 and Figure 4In one embodiment, the direct vibration track 300 includes a vibration plate 310, a guide rail 320, a direct vibrator 330 and a positioning platform 340. The vibration plate 310 and the positioning platform 340 are respectively located at the two ends of the guide rail 320. The guide rail 320 is set on the direct vibrator 330. The O-ring 22 is stored in the vibration plate 310. The O-ring 22 is fed into the guide rail 320 through the vibration plate 310. The direct vibrator 330 drives the guide rail 320 to vibrate to drive the O-ring 22 to move toward the positioning platform 340. The positioning platform 340 is located at the end of the guide rail 320. The O-ring 22 stops moving forward after reaching the positioning platform 340, and only one O-ring 22 can be accommodated in the positioning platform 340. The positioning platform 340 is used as a position reference. The material picking robot 400 picks up the O-ring 22 located in the positioning platform 340 when picking up materials.

[0059] See also Figure 4 and Figure 5 Furthermore, the positioning platform 340 includes an adjustment frame 341 and a stopper 342. The stopper 342 is arranged on the adjustment frame 341. A limiting groove 342a is provided on the side of the stopper 342 close to the guide rail 320. The limiting groove 342a is used to accommodate the O-ring 22. The extension length of the limiting groove 342a is consistent with the outer diameter of the O-ring 22. The limiting groove 342a is connected to the guide rail 320. The O-ring 22 transmitted along the guide rail 320 directly enters the limiting groove 342a. The first O-ring 22 is blocked by the groove wall of the limiting groove 342a. The blocked O-ring 22 is the target to be loaded.

[0060] It should be noted that when the material picking robot 400 picks up the O-ring 22 in the limiting groove 342a, the material picking rod 410 needs to penetrate the O-ring 22, wherein the diameter of the material picking rod 410 is larger than the inner diameter of the O-ring 22. When the material picking rod 410 penetrates the O-ring 22, an axial impact force is applied to the O-ring 22, which will cause the O-ring 22 to deform. When the O-ring 22 is deformed, an elastic force is generated to cause it to jump out of the limiting groove 342a and detach from the limiting groove 342a, resulting in material picking failure, that is, the material picking rod 410 has the problem of unstable material picking.

[0061] See also Figure 5 and Fig. 9 To solve the above problem, the positioning platform 340 also includes two anti-jumping baffles 343; the width of the anti-jumping baffles 343 is smaller than the width of the avoidance groove 411 on the material picking rod 410, that is, the anti-jumping baffles 343 can penetrate the avoidance groove 411.

[0062] The two anti-jumping baffles 343 are rotatably disposed on the baffle 342, and the two anti-jumping baffles 343 are distributed in a mirror image with the limiting groove 342a as the center;

[0063] The stopper 342 is provided with a limiting step 342b and a blocking slope 342c. The limiting step 342b is used to prevent the anti-jumping baffle 343 from rotating in the direction close to the limiting groove 342a. In the initial state, the anti-jumping baffle 343 is flatly laid above the limiting groove 342a and abuts against the limiting step 342b. The limiting step 342b keeps the two anti-jumping baffles 343 flush (such as Figure 8 shown).

[0064] The blocking slope 342c is used to prevent the anti-jumping baffle 343 from rotating in the direction away from the limiting groove 342a. That is, after the anti-jumping baffle 343 rotates in the direction away from the limiting groove 342a, it will abut against the blocking slope 342c, and the blocking slope 342c limits the rotation angle of the anti-jumping baffle 343 (such as Fig. 9 shown);

[0065] When the material picking robot 400 picks up the O-ring 22, the working state of the anti-jump baffle 343 is as follows:

[0066] See also Figure 5 After the material-grabbing manipulator 400 moves to the top of the stopper 342, two of the avoidance grooves 411 on the material-grabbing rod 410 are aligned with the two anti-jumping baffles 343 on the stopper 342, and the material-grabbing rod 410 begins to descend;

[0067] See also Figure 6 When the material taking rod 410 contacts the O-ring 22, an axial impact force is generated on the O-ring 22. At this time, the two anti-jumping baffles 343 laid flat on the limiting groove 342a form a barrier to prevent the O-ring 22 from jumping out of the limiting groove 342a, thereby ensuring that the material taking rod 410 can smoothly penetrate the O-ring 22;

[0068] Since the diameter of the material taking rod 410 is larger than the O-ring 22, when the material taking rod 410 passes through, the O-ring 22 is deformed and generates elastic force to wrap itself around the outer wall of the material taking rod 410;

[0069] See also Figure 7 When the picking rod 410 rises, the O-ring 22 rises accordingly and pushes the two anti-jump baffles 343 to rotate in a direction away from the limiting groove 342a. The distance between the ends of the two anti-jump baffles 343 increases accordingly until the O-ring 22 is out of the blocking range of the anti-jump baffles 343. The O-ring 22 moves with the picking rod 410 to the extended air claw 510 for assembly. After losing the support of the O-ring 22, the two anti-jump baffles 343 reverse and are re-laid above the limiting groove 342a.

[0070] In this way, when the material picking robot 400 performs the material picking operation, the two anti-jumping baffles 343 cover the top of the O-ring 22 to prevent it from escaping from the limiting groove 342a, so that the material picking process of the O-ring 22 is stable and reliable.

[0071] See also Fig. 9 Preferably, a magnet 344 is embedded in the anti-jumping baffle 343, and an iron gasket 345 matching the magnet 344 is arranged in the limiting step 342b, so that when the anti-jumping baffle 343 abuts against the limiting step 342b, the magnet 344 fits with the iron gasket 345, and the magnet 344 and the iron gasket 345 are adsorbed together, and the anti-jumping baffle 343 and the limiting step 342b are directly matched together through the magnetic attraction between the magnet 344 and the iron gasket 345. The magnet 344 is a weak magnet, which only provides magnetic attraction to ensure that the anti-jumping baffle 343 will not be stretched open when the O-ring 22 jumps. The magnetic attraction provided by the magnet 344 is smaller than the friction between the O-ring 22 and the material picking rod 410, that is, when the material picking rod 410 rises, the O-ring 22 will not be scraped off by the anti-jumping baffle 343, further improving the stability of the O-ring 22 feeding process.
