Description

Technical Field

[0001] This application relates to the technical field of assembly of end caps, and in particular to an automatic assembly production equipment for end caps with rubber rings. Background Technology

[0002] PVC mandrel valves are mainly used to cut off or connect the medium in pipelines. They can also be used for fluid regulation and control. They are commonly used in pipeline systems for pure water and drinking water, drainage and sewage, as well as brine and seawater.

[0003] In the present technology, the control valve typically includes a valve body and a sealing end cap. The valve body contains a valve core and a ball core. The ball core has a through hole. The valve core is connected to the ball core, which drives the ball core to rotate. The two ends of the plastic valve body are respectively provided with an inlet end and an outlet end.

[0004] To improve the sealing effect between the end cover and the valve body during assembly, the rubber ring and gasket are usually placed around the outer circumference of the end cover in sequence, and then the end cover is placed into the cavity of the valve and tightened to complete the assembly of the valve.

[0005] During assembly, to facilitate the installation of the rubber ring, it needs to be expanded outwards so that it can be fitted onto the outer circumference of the end cap. Currently, the rubber ring and washer are usually fitted onto the outer circumference of the end cap manually, which significantly affects both assembly efficiency and accuracy. Utility Model Content

[0006] To ensure the assembly accuracy of valves and improve assembly efficiency, this application provides an automatic assembly production equipment for valves using end cap rubber rings.

[0007] This application provides a technical solution for an automatic assembly production equipment for end cap rubber rings, which employs the following method:

[0008] An automatic assembly production equipment for end caps and rubber rings includes a worktable, a conveying mechanism, an end cap feeding mechanism, a rubber ring assembly mechanism, and a gasket assembly mechanism. The conveying mechanism is connected to the worktable and is used to convey end caps horizontally. The end cap feeding mechanism, rubber ring assembly mechanism, and gasket assembly mechanism are arranged sequentially along the conveying direction of the conveying mechanism. The end cap feeding mechanism is used to place the end caps one by one onto the conveying mechanism. The rubber ring assembly mechanism and gasket assembly mechanism are connected to the worktable and are used to fit the rubber rings onto the end caps. The gasket assembly mechanism is used to fit the gaskets onto the end caps.

[0009] By adopting the above technical solution, when assembling the end caps using the above equipment, the end caps are placed one by one on the conveying mechanism by the end cap feeding mechanism, and then the end caps are slid by the conveying mechanism. The end caps pass through the rubber ring assembly mechanism and the gasket assembly mechanism in sequence. The rubber ring assembly mechanism puts the rubber ring on the outer circumference of the end cap, and the gasket assembly mechanism puts the gasket on the outer circumference of the end cap, so as to realize the continuous and precise assembly of the rubber ring and the gasket, save labor, improve the assembly efficiency of the end caps, and ensure the assembly accuracy of the end caps.

[0010] Preferably, the end cap feeding mechanism includes an end cap feeding elevator, a discharge hopper, a guide rod, and a discharge slide. The end cap feeding elevator is used to drive the end cap to move vertically. The discharge hopper is connected to one side of the end cap feeding indicator in the horizontal direction. The discharge hopper has a feed inlet on the side near the end cap feeding elevator. The lower end of the guide rod is connected to the side of the end cap feeding elevator away from the discharge hopper. The upper end of the guide rod extends into the feed inlet. The length direction of the guide rod is inclined to the conveying direction of the end cap feeding elevator. The lower end of the discharge hopper has a discharge outlet on the side away from the end cap feeding elevator. The upper end of the discharge slide is connected to the discharge hopper. The lower end of the discharge slide is located above the conveying mechanism. The discharge slide has a guide groove. The guide groove is connected to the discharge outlet. The groove wall is in contact with the outer wall of the end cap.

[0011] By adopting the above technical solution, the end cap feeding elevator drives the end cap to move. When the groove on the outer circumference of the end cap is not aligned with the guide rod, the guide rod pushes the end cap out, causing the end cap to fall back into the end cap feeding elevator. When the groove on the outer circumference of the end cap is aligned with the guide rod, the guide rod is embedded in the groove, allowing the end cap to slide along the guide rod into the feed inlet and then into the guide groove through the discharge outlet. This ensures that the end caps conveyed to the conveying mechanism maintain a consistent orientation, facilitating the subsequent assembly of rubber rings and gaskets onto the end caps.

[0012] Preferably, the end cap feeding mechanism further includes a guide plate and a hopper. The hopper is connected to the end cap feeding elevator. The lower end of the hopper is in contact with the upper surface of the end cap feeding elevator. The upper end of the hopper is gradually widened in the vertical direction away from the lower end of the hopper. The guide plate is connected to the side of the end cap feeding elevator near the hopper. There are two guide plates, which are symmetrically distributed in the horizontal direction.

[0013] By adopting the above technical solution, a guide plate and a hopper are set up to protect the end cover and prevent it from falling off and detaching from the end cover feeding elevator, thereby improving the automation level of the equipment.

[0014] Preferably, there are two rubber ring assembly mechanisms, which are distributed at intervals along the conveying direction of the conveying mechanism.

[0015] By adopting the above technical solution and setting up two rubber ring assembly mechanisms, it is helpful to assemble the two rubber rings fitted on the outer periphery of the end cap separately, thereby improving work efficiency.

[0016] Preferably, the rubber ring assembly mechanism includes a first conveyor belt, a first feeding detection photoelectric sensor, a first picking cylinder, a first up-and-down assembly, and a first lateral movement assembly. The first conveyor belt is used to convey the rubber ring, and a first feeding standby position is provided on the side of the first conveyor belt near the conveying mechanism. The first feeding detection photoelectric sensor is connected to the first conveyor belt and is used to detect whether a rubber ring exists in the first feeding standby position. The first picking cylinder is used to clamp the rubber ring and sleeve it on the outer periphery of the end cap. The first up-and-down assembly is connected to the worktable and is used to drive the first picking cylinder to move in the vertical direction. The first lateral movement assembly is connected to the worktable and is used to drive the first picking cylinder to move in the horizontal direction.

[0017] By adopting the above technical solution, a first material-grabbing cylinder is set up to clamp the rubber ring. The first horizontal moving component and the first vertical moving component realize the movement of the first material-grabbing cylinder in the horizontal and vertical directions, thereby realizing the automatic feeding and assembly of the rubber ring, ensuring the consistency of rubber ring material handling and feeding, and realizing efficient and precise assembly of the rubber ring.

[0018] Preferably, the rubber ring assembly mechanism further includes a first gripper and an inner support assembly. The inner support assembly includes a placement platform and a six-jaw cylinder. The placement platform is connected to the workbench and is located on the side of the first conveyor belt near the conveying mechanism. The six-jaw cylinder is connected to the placement platform to expand the rubber ring. The first gripper is used to transport the rubber ring from the first loading standby position to the placement platform.

[0019] By adopting the above technical solution, setting an inner support component and a first gripper, while the first picking cylinder takes away the rubber ring and assembles it on the end cap, the first gripper places the next rubber ring on the placement platform, and the six-jaw cylinder opens the rubber ring, making it easy to put the rubber ring on the first picking cylinder, thus achieving efficient and precise assembly of the rubber ring.

[0020] Preferably, the washer assembly mechanism includes a feeding circular vibrating slide, a second feeding detection photoelectric sensor, a second gripper, a second up-and-down assembly, and a second lateral movement assembly. The feeding circular vibrating slide is used to convey washers. A second feeding standby position is provided on the side of the feeding circular vibrating slide near the conveying mechanism. The second feeding detection photoelectric sensor is connected to the feeding circular vibrating slide and is used to detect whether a washer is present in the second feeding standby position. The second gripper is used to clamp the washer and fit it around the outer periphery of the end cap. The second up-and-down assembly is connected to the worktable and is used to drive the second gripper to move vertically. The second lateral movement assembly is connected to the worktable and is used to drive the second gripper to move horizontally.

[0021] By adopting the above technical solution, a second gripper is set to hold the gasket. The second gripper moves in the horizontal and vertical directions through the second lateral movement component and the second vertical movement component, thereby realizing the automatic feeding and assembly of the gasket, ensuring the consistency of gasket feeding and handling, and achieving efficient and precise assembly of the gasket.

[0022] Preferably, the assembly further includes positioning components. The number of positioning components is the same as and corresponds one-to-one with the number of rubber ring assembly mechanisms and gasket assembly mechanisms. Each positioning component includes a positioning drive cylinder and a positioning block. The positioning block is slidably connected to the conveying mechanism. The sliding direction of the positioning block is perpendicular to the conveying direction of the conveying mechanism. One end of the positioning block is used to abut against the outer wall of the end cap. There are four positioning blocks, which are divided into two groups. The two groups of positioning blocks are symmetrically distributed along the conveying direction perpendicular to the conveying mechanism. The two positioning blocks in the same group are symmetrically distributed along the conveying direction of the conveying mechanism. The number of positioning drive cylinders is the same as and corresponds one-to-one with the number of positioning blocks. The positioning drive cylinders are connected to the conveying mechanism and are used to drive the positioning blocks to slide.

[0023] By adopting the above technical solution, the positioning drive cylinder pushes the positioning block to slide, so that the positioning block abuts against the outer wall of the end cover, thereby achieving the positioning of the end cover, reducing the possibility of the end cover moving horizontally during the assembly of the rubber ring and gasket, and improving the assembly accuracy of the equipment.

[0024] Preferably, the positioning block has a contact surface on the side near the end cap to be processed, and the contact surface is in contact with the outer wall of the end cap.

[0025] By adopting the above technical solution, the positioning block is provided with a contact surface, which is used to contact the outer wall of the end cap, thereby improving the stability of the connection between the positioning block and the end cap assembly.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When using the above equipment to assemble end caps, the end caps are placed one by one on the conveying mechanism by the end cap feeding mechanism, and then the end caps are slid by the conveying mechanism. The end caps pass through the rubber ring assembly mechanism and the gasket assembly mechanism in sequence. The rubber ring assembly mechanism puts the rubber ring on the outer circumference of the end cap, and the gasket assembly mechanism puts the gasket on the outer circumference of the end cap, so as to realize the continuous and precise assembly of the rubber ring and the gasket, save labor, improve the assembly efficiency of the end caps, and ensure the assembly accuracy of the end caps.

[0028] 2. A first picking cylinder is set up to clamp the rubber ring. The first picking cylinder moves in the horizontal and vertical directions through the first transverse component and the first up and down component, thereby realizing the automatic feeding and assembly of the rubber ring. An inner support component and a first gripper are set up. While the first picking cylinder picks up the rubber ring and assembles it on the end cap, the first gripper places the next rubber ring on the placement table. The six-jaw cylinder opens the rubber ring, making it easy to put the rubber ring on the first picking cylinder, ensuring the consistency of rubber ring feeding and arrangement, and realizing efficient and precise assembly of the rubber ring.

[0029] 3. A second gripper is provided to hold the gasket. The second gripper moves in the horizontal and vertical directions through the second lateral movement component and the second vertical movement component, thereby realizing automatic feeding and assembly of the gasket, ensuring the consistency of gasket feeding and handling, and achieving efficient and precise assembly of the gasket.

When the end cap abuts the guide rod 33, the end cap slides along the guide rod 33 towards the discharge hopper 32. After passing through the feed inlet 321, the end cap enters the receiving cavity 323. The end cap enters the guide groove 341 from the discharge outlet 322 and slides along the guide groove 341 to the top of the feeding conveyor belt 21. The feeding conveyor belt 21 drives the end cap to move.

[0057] When the end cap is located below the rubber ring assembly mechanism 4, the piston rod of the positioning drive cylinder 612 extends and pushes the positioning block 611 to slide, so that the mating surface 6111 fits against the outer wall of the end cap, thereby achieving the positioning of the end cap. The piston rod of the first up-and-down cylinder 443 extends, pushing the first up-and-down sliding seat 442 to slide, causing the first gripper 46 to move down and grip the rubber ring located in the first loading standby position 411. The first picking cylinder 43 moves down, and the six-jaw cylinder 472 releases the rubber ring, so that the rubber ring is fitted onto the first picking cylinder 43. The piston rod of the first up-and-down cylinder 443 retracts, causing the first up-and-down sliding seat 442 to move up, causing the first gripper 46 and the first picking cylinder 43 to move up. The piston rod of the first transverse cylinder 453 extends, pushing the first transverse sliding seat 452 to slide, so that the first gripper 46 is aligned with the placement table 471 and the first picking cylinder 43 is aligned with the end cap. The piston rod of the first up-and-down cylinder 443 extends, pushing the first up-and-down sliding seat 442 to slide, causing the first gripper 46 to move down and place the rubber ring on the placement table 471. The six-jaw cylinder 472 operates, opening the rubber ring. The first picking cylinder 43 moves down and fits the rubber ring onto the outer circumference of the end cap.

[0058] The piston rod of the positioning drive cylinder 612 retracts, pushing the positioning block 611 to slide, so that the positioning block 611 moves away from the end cover, and the end cover moves with the feeding conveyor belt 21.

[0059] When the end cap is below the washer assembly mechanism 5, the piston rod of the positioning drive cylinder 612 extends, pushing the positioning block 611 to slide, so that the mating surface 6111 fits against the outer wall of the end cap, thus positioning the end cap. The piston rod of the second upper and lower cylinder 543 extends, pushing the second upper and lower sliding seat 542 to slide, causing the second gripper 53 to move down and pick up the washer located in the second loading standby position 511. The piston rod of the second upper and lower cylinder 543 retracts, causing the second upper and lower sliding seat 542 to move up, causing the second gripper 53 to move up. The piston rod of the second transverse cylinder 553 extends, pushing the second transverse sliding seat 552 to slide, so that the second gripper 53 aligns with the end cap. The piston rod of the second upper and lower cylinder 543 extends, pushing the second upper and lower sliding seat 542 to slide, causing the second gripper 53 to move down, and placing the washer on the outer circumference of the end cap.

[0060] The piston rod of the positioning drive cylinder 612 retracts, pushing the positioning block 611 to slide, so that the positioning block 611 moves away from the end cover, and the end cover moves with the feeding conveyor belt 21.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
