Description

Technical Field

[0001] The invention relates to the field of waterproof breathable valve production, and in particular to a waterproof breathable valve body transfer device. Background Art

[0002] In the process of using equipment to automatically assemble waterproof and breathable valves, the valve body is usually transferred by a conveyor belt and a robot, and the valve body is transported to each assembly station. The assembly robot then installs each accessory into the valve body one by one.

[0003] Among them, the production and assembly of the valve body are carried out on different equipment, and then transferred by the transmission device between the two. It is understandable that there is a difference in the production and processing of the valve body and the assembly efficiency of the valve body. Since the sealing ring, valve core, isolation bracket, breathable membrane, protective cover and other components need to be installed into the valve body one by one, the assembly time of the valve body is much greater than the production efficiency of the valve body itself. In this way, the valve body produced by the production equipment will be detained on the transmission device. In order to maintain normal production, the transmission device needs to set up a lengthy buffer area to store the valve body to be assembled, which will make the assembly line occupy a large area.

[0004] Therefore, how to store the valve bodies to be assembled on the production line and reduce the size of the equipment is a problem that needs to be solved. Summary of the invention

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0043] See also Figure 2 The present invention provides a waterproof breathable valve body transfer device 10, which is used for loading and unloading valve bodies 20, including: a frame 100, a first conveyor belt 200, a second conveyor belt 300, a transfer mechanism 400, a handling robot 500 and a plurality of trays 600 for storing valve bodies.

[0044] See also Figure 2 The frame 100 is provided with a workbench 110 and a storage bin 120. The workbench 110 is located above the storage bin 120. The first conveyor belt 200 and the second conveyor belt 300 are arranged in the storage bin 120 at intervals. Specifically, the first conveyor belt 200 transports the material tray 600 carrying the valve body 20 into the storage bin 120, and the second conveyor belt 300 transports the empty material tray 600 away from the storage bin 120. The first conveyor belt 200 and the second conveyor belt 300 are both provided with a lifting frame 130. The workbench 110 is provided with a loading port 111 and a unloading port 112 connected with the storage bin 120. The loading port 111 faces the first conveyor belt 200, and the unloading port 112 faces the second conveyor belt 300.

[0045] The tray 600 is used to store the valve bodies 20 to be assembled, and the trays 600 can be stacked. The stacked trays 600 are placed on the first conveyor belt 200. When the first conveyor belt 200 moves the trays 600 to below the loading port 111, the lifting frame 130 lifts the trays 600, and the top tray 600 enters the loading port 111. At this time, the valve bodies 20 in the trays 600 are within the picking range of the handling robot 500. The handling robot 500 grabs the valve bodies 20 in the trays 600 and puts them into the next assembly station.

[0046] The transfer mechanism 400 and the handling robot 500 are both located on the workbench 110. The handling robot 500 is used to pick up the valve body in the material tray 600. The transfer mechanism 400 is provided with a slide 410, a clamping cylinder 420 and two clamping claws 430 arranged opposite to each other. The clamping cylinder 420 is used to drive the two clamping claws 430 to clamp the material tray 600. The slide 410 can drive the clamping cylinder 420 to translate above the loading port 111 and the unloading port 112.

[0047] The slide 410 includes a translation cylinder 411 and a lifting cylinder 412 . The translation cylinder 411 is used to drive the clamping cylinder 420 to translate between the loading port 111 and the unloading port 112 . The lifting cylinder 412 is used to drive the clamping cylinder 420 to move closer to or away from the workbench 110 .

[0048] When all the valve bodies 20 in the tray 600 in the loading port 111 are loaded, the lifting frame 130 at the loading port 111 pushes the tray 600 up, the clamping cylinder 420 is started, the clamping claws 430 move closer to each other and clamp the outer wall of the empty tray 600, and the slide 410 transfers the grabbed empty tray 600 to the unloading port 112, and at this time the lifting frame 130 at the unloading port 112 is lowered. Specifically, each time an empty tray 600 is placed at the unloading port 112, the lifting frame 130 is lowered once, so that the empty trays 600 are stacked at the unloading port 112, and finally the stacked empty trays 600 are placed on the second conveyor belt 300, and the empty trays 600 are transported away by the second conveyor belt 300.

[0049] In one embodiment, please refer to Figure 3 A reflective sensor 421 is provided on the outer wall of the clamping cylinder 420 .

[0050] Compared with the prior art, the waterproof breathable valve body transfer device 10 has the following advantages:

[0051] 1. The valve body is stored in the material tray 600, and the material tray 600 can be stacked, which can increase the storage capacity of the valve body per unit area;

[0052] 2. The rack 100 is arranged in layers, and the first conveyor belt 200 and the second conveyor belt 300 are both arranged in the storage bin 120, without occupying the space on the workbench 110. The lifting frame 130 is used to lift the material tray 600 for the transport robot 500 to pick up the material, thereby improving the space utilization rate of the equipment.

[0053] 3. The empty material tray 600 is transferred to the material discharge port 112 by the transfer mechanism 400 and then removed by the second conveyor belt 300, thereby preventing the material from piling up at the rack 100.

[0054] It should be noted that in order to improve equipment utilization and reduce production costs in the actual production process, the same production line needs to complete the assembly tasks of multiple styles of waterproof and breathable valves, which means that the above-mentioned waterproof and breathable valve body transfer device 10 needs to load different styles of valve bodies 20, and the structures of different styles of valve bodies 20 are different. The existing production line needs to load three different styles of valve bodies (such as Figure 1 As shown in the figure, from left to right in the figure, valve body A, valve body B and valve body C are respectively shown. The flange 21 of the above valve bodies are all hexagonal. The main difference is the length of the tube body 22 on the upper side of the flange 21. The upper end opening 23 of the tube body 22 is required to ensure that the opening 23 faces upward during the loading action. Due to the difference in the length of the tube body 22, in order to make the material tray 600 able to adapt to the above three valve bodies at the same time, it is necessary to install a column 24 (as shown in the figure) on the material tray 600. Fig.14 As shown in the figure, two adjacent trays 600 are separated by the columns 24, so that there is an escape space between the upper and lower trays 600, and the tube bodies 22 of the valve bodies B and C can be accommodated in the escape space. Although this embodiment can make the trays 600 adapt to different styles of valve bodies, the number of trays 600 that can be stacked in the storage bin 120 is reduced because the columns 24 are fixed on the trays 600; it cannot be ignored that the columns 24 cause intervals between the trays 600, and the center of gravity of the trays 600 becomes higher after stacking, that is, its ability to resist collapse is also reduced, especially after the valve body 20 is removed, the trays 600 will become lighter, and the ability to resist collapse will be further weakened, and the second conveyor belt 300 is prone to collapse when transporting empty trays 600.

[0055] To solve the above problems, please refer to Figure 4 and Figure 8 The transfer mechanism 400 is provided with a detection block 440, and the edge of the clamping claw 430 is provided with an avoidance groove 431 (such as Figure 3 As shown in FIG. 4 , the detection block 440 includes a main body 441, a detection part 442 and a stopper 443. The detection part 442 and the stopper 443 are respectively arranged at both ends of the main body 441, and the detection part 442 and the stopper 443 are located on the same side of the main body 441. The main body 441, the detection part 442 and the stopper 443 together form a "C"-shaped structure. The main body 441 is rotatably arranged in the avoidance groove 431. The connecting fulcrum 13 between the main body 441 and the avoidance groove 431 is the rotation center of the detection block 440. The length of the detection part 442 is greater than the length of the stopper 443. A through hole 610 is opened on the side of the material tray 600, and the detection part 442 is penetrated by the through hole 610. Preferably, in order to avoid scratching, an anti-scratch arc 442a is provided at the end of the detection part 442.

[0056] In this way, when the transfer mechanism 400 picks up the tray 600, the clamping claw 430 approaches the tray 600, so that the detection part 442 on the detection block 440 will pass through the through hole 610 and extend into the tray 600. Depending on whether the valve body 20 is stored in the tray 600, the detection block 440 has the following two different states:

[0057] 1. Please refer to Fig. 9 When the valve body 20 is not stored in the material tray 600, the detection block 440 does not deflect, the detection portion 442 directly penetrates into the material tray 600, and the stopper 443 faces the side wall of the material tray 600;

[0058] 2. Please refer to Figure 8 When the valve body 20 is stored in the material tray 600, the detection block 440 will deflect. Specifically, the detection portion 442 first passes through the through hole 610. When it extends into the material tray 600, since the storage hole in the material tray 600 stores the valve body 20, the valve body 20 prevents the detection portion 442 from continuing to extend, thereby causing the detection block 440 to rotate around the fulcrum 13. At this time, the stopper 443 tilts toward the side close to the detection portion 442.

[0059] A first torsion spring (not shown) is provided at the connection position between the detection block 440 and the avoidance groove 431. After the clamping jaw 430 is separated from the material tray 600, the first torsion spring can provide elastic force to reverse the detection block 440 and restore it to its initial state.

[0060] For further information, see Figure 5 and Fig.13 An outer support assembly 700 is provided on the outer wall of the material tray 600 , and the outer support assembly 700 includes a frame body 710 and a bearing block 720 , a movable block 730 , a locking rod 740 , and a limiting claw 750 located in the frame body 710 .

[0061] See also Figure 5 and Fig.13 A guide rail 711 is provided in the frame 710, and the guide rail 711 extends in the vertical direction, where the vertical direction refers to the direction perpendicular to the upper end surface of the material tray 600. A tension spring 712 is provided at the end of the guide rail 711, and the tension spring 712 is connected to the supporting block 720. The tension spring 712 can provide elastic force to pull the supporting block 720 toward the end of the guide rail 711. A contact portion 721 is provided on the end of the supporting block 720 away from the guide rail 711, and the contact portion 721 is inclined toward the end of the guide rail 711, and the contact portion 721 is toward the position of the movable block 730.

[0062] See also Figure 6 The movable block 730 is provided with a first inclined surface 731, a limiting step 732 and a second inclined surface 733, the first inclined surface 731 is in contact with the contact portion 721, the second inclined surface 733 is located outside the frame 710, and the clamping jaw 430 is provided with a contact surface 432 (such as Figure 8 As shown in the figure, when the clamping jaw 430 approaches the material tray 600, the contact surface 432 pushes the movable block 730, causing the movable block 730 to slide toward the position of the supporting block 720, and under the guidance of the first inclined surface 731, the supporting block 720 moves in a direction away from the end of the guide rail 711, and then extends out of the frame 710. The portion of the supporting block 720 exposed outside the frame 710 can be used to support the upper material tray 600, so that there is a gap between the upper and lower material trays 600 when the material trays 600 are stacked (as shown in the figure). Fig.15 As shown), the material tray 600 meets the storage conditions of valve body B and valve body C.

[0063] See also Figure 5 and Figure 7 A return spring 734 is provided on the side of the movable block 730 that contacts the material tray 600. After the clamping jaw 430 is separated from the material tray 600, the return spring 734 provides elastic force to push the movable block 730 to return to its original position.

[0064] See also Fig.10 and Fig.11 There are two limit claws 750, which are arranged facing each other, and each limit claw 750 is provided with a second torsion spring (not shown), which provides elastic force to flip the limit claw 750 toward the position of the movable block 730, and a clamping tooth 751 is provided at the position where the limit claw 750 contacts the limit step 732. The limit claw 750 is located on the translation track of the movable block 730. After the movable block 730 moves toward the side where the bearing block 720 is located, the clamping tooth 751 will clamp the limit step 732, lock the movable block 730, and then keep the bearing block 720 in an extended state, so as to facilitate the stacking of the tray 600.

[0065] See also Figure 5 and Fig.13 The locking rod 740 includes a rod body 741, an unlocking portion 742 and a pressing portion 743. The unlocking portion 742 and the pressing portion 743 are respectively located at two ends of the rod body 741. The movable block 730 is provided with a sliding groove 735 (such as Figure 6 As shown in FIG. 1 , the rod body 741 is accommodated in the slide groove 735, and the rod body 741 can slide along the slide groove 735. A stop spring 744 is provided between the rod body 741 and the inner wall of the slide groove 735. The stop spring 744 provides an elastic force to push the rod body 741 to slide toward the side away from the first inclined surface 731 (as shown in FIG. 1 ). Figure 7 The unlocking portion 742 is conical, and the initial position of the unlocking portion 742 is on the side away from the bearing block 720 as shown in FIG. Fig.10As shown, when the rod body 741 slides along the sliding groove 735 toward the first inclined surface 731, the unlocking portion 742 will pass through the limiting claw 750. Since the unlocking portion 742 is conical, the limiting claw 750 can be opened when it passes through the limiting claw 750, thereby releasing the locking of the movable block 730 by the limiting claw 750.

[0066] See also Figure 5 and Figure 7 The pressing portion 743 is located outside the frame 710, and a third inclined surface 11 and a stop protrusion 12 are provided on the pressing portion 743. The movable block 730 is provided with a limiting portion 736 matching the stop protrusion 12. When the movable block 730 translates in a direction away from the bearing block 720, the limiting portion 736 abuts against the stop protrusion 12, and the third inclined surface 11 is used to abut against the stop portion 443. Since the detection block 440 has two different states when the clamping jaw 430 clamps the material tray 600, this will cause the stop portion 443 to contact the third inclined surface 11 in different states, which will specifically produce the following two effects:

[0067] 1. When the valve body 20 is not stored in the material tray 600, the detection block 440 does not deflect, and the stopper 443 faces the material tray 600 (e.g. Fig. 9 As shown), at this time, the stopper 443 and the detector 442 are distributed on both sides of the fulcrum 13 to form a lever structure. The thrust generated by the contact between the stopper 443 and the third inclined surface 11 causes the stopper 443 to have a tendency to swing away from the detector 442. However, at this time, the detector 442 extends into the interior of the material tray 600, and the material tray 600 provides a blocking force to prevent the detection block 440 from deflecting. The stopper 443 cannot move, and the reaction force generated is applied to the third inclined surface 11, so that the locking rod 740 slides toward the position of the bearing block 720, and the unlocking portion 742 moves to the side close to the bearing block 720. Fig.11 As shown;

[0068] 2. When the valve body 20 is stored in the material tray 600, the detection block 440 will deflect, and the stopper 443 will tilt toward the side close to the detection part 442. When it contacts the third inclined surface 11, the stopper 443 and the detection part 442 are distributed on the same side of the fulcrum 13, so that the force generated when the stopper 443 contacts the third inclined surface 11 will become a thrust, pushing the stopper 443 to continue to deviate toward the detection part 442. In this way, the stopper 443 cannot generate enough reaction force to overcome the thrust generated by the stop spring 744 to make the locking rod 740 slide, and the unlocking part 742 is still in its initial position. Fig.10 shown.

[0069] By optimizing the transfer mechanism 400 and the material tray 600, the transfer mechanism 400 can be made to keep the original clamping action of the material tray 600 so that the material tray 600 can meet the storage requirements of valve bodies 20 of different specifications. The working principle of the cooperation between the detection block 440 and the outer support assembly 700 is as follows:

[0070] After the material trays 600 are stacked with the valve bodies 20, the movable block 730 is located on the side close to the bearing block 720, the bearing block 720 is lifted up by the movable block 730, and the limiting claw 750 buckles the limiting step 732 to lock the movable block 730. At this time, the bearing block 720 is in an extended state, and there is a gap between the upper and lower material trays 600;

[0071] After the handling robot 500 has transferred all the valve bodies 20 in the tray 600, the clamping cylinder 420 drives the clamping claw 430 to clamp the empty tray 600. When the clamping claw 430 approaches the empty tray 600, the detection part 442 passes through the through hole 610 and extends into the empty tray 600. At this time, the detection block 440 does not deflect (such as Fig. 9 shown);

[0072] The stopper 443 contacts the third inclined surface 11, and the clamping force of the clamping jaw 430 acts on the third inclined surface 11, so that the locking rod 740 slides toward the position of the bearing block 720 and pushes the unlocking portion 742 toward the limiting claw 750. When the clamping jaw 430 completes the clamping action, the unlocking portion 742 moves to the side close to the first inclined surface 731, that is, the position of the unlocking portion 742 is changed from Fig.10 Changes to Fig.11 As shown, at this time, the unlocking portion 742 is in a pre-unlocking state;

[0073] After the empty material tray 600 is transferred to the discharge port 112, the clamping jaw 430 will release the material tray 600. As the clamping jaw 430 leaves the material tray 600, the contact surface 432 on the clamping jaw 430 separates from the second inclined surface 733, and the return spring 734 provides elastic force to push the movable block 730 and the unlocking portion 742 to move together in a direction away from the supporting block 720. Since the unlocking portion 742 is conical, the limiting claw 750 can be opened to separate the limiting claw 750 from the limiting step 732, and the locking of the movable block 730 is released. The movable block 730 moves in a direction away from the supporting block 720, and the supporting block 720 retracts into the frame 710. Fig.12 shown.

[0074] Among them, when the movable block 730 translates in the direction away from the supporting block 720, the tension spring 712 pulls the supporting block 720 to move toward the end of the guide rail 711, so that the supporting block 720 retracts into the frame 710. In this way, when stacking empty trays 600, the intervals between the trays 600 are small, which can reduce the center of gravity of the empty trays 600 after stacking, and reduce the probability of collapse during transportation. In addition, since the supporting block 720 is retracted into the frame 710, the height of a single tray 600 is reduced, and more trays 600 can be stacked in the storage bin 120, which is convenient for batch recovery of trays 600.

[0075] Furthermore, the outer support assembly 700 and the transfer mechanism 400 can also be used in the process of loading the valve body 20 into the material tray 600, as follows:

[0076] After the manipulator puts the valve body 20 into the empty tray 600, it is moved away by the transfer mechanism 400. When the clamp 430 clamps the tray 600 with the valve body 20, the detection part 442 extends into the tray 600. Since the tray 600 is equipped with the valve body 20 at this time, the detection part 442 is blocked, so that the detection block 440 deflects around the fulcrum 13, and the stopper 443 tilts toward the side where the detection part 442 is located. Figure 8 As shown;

[0077] In this way, when the stopper 443 contacts the third inclined surface 11, the third inclined surface 11 further pushes the detection block 440 to deflect. At the same time, the contact surface 432 contacts the second inclined surface 733 and pushes the movable block 730 to slide toward the position of the bearing block 720. Under the guidance of the first inclined surface 731, the bearing block 720 is lifted up, so that the bearing block 720 extends out of the frame 710.

[0078] When the movable block 730 moves toward the bearing block 720, the limiting step 732 passes through the limiting claw 750 and is caught by the tooth 751, and the limiting claw 750 locks the movable block 730, so that the bearing block 720 is kept in the extended state. Fig.10 In this way, after the material trays 600 are stacked, there is a gap between the upper and lower layers, so that the material trays 600 can be loaded with valve bodies 20 of different styles.

[0079] It can be seen that when the clamping claw 430 clamps the material tray 600, the detection block 440 can determine whether the clamped material tray 600 is an empty material tray. When the valve body 20 is installed in the material tray 600, the locking of the movable block 730 by the limit clamp 750 will not be released, so that the supporting block 720 remains in the extended state. Without changing the original movement of the transfer mechanism 400, the material trays 600 are automatically separated after being stacked, so that the material trays 600 can be loaded with valve bodies 20 of different specifications, and the initial state is restored after the valve body 20 is removed, so that the empty material trays 600 are in close contact after being stacked, reducing the risk of collapse.

[0080] In one embodiment, please refer to Fig.13 and Fig.15 The top of the bearing block 720 is provided with a positioning protrusion 722, the cross section of which is conical, and the bottom of the frame 710 is provided with a positioning groove 713 matching the positioning protrusion 722. When stacking the trays 600, the positioning protrusion 722 on the lower tray 600 can be embedded in the positioning groove 713 of the upper tray 600, further improving the stability of the stacked trays 600 and preventing them from collapsing during transportation.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
