Description

Technical Field

[0001] This invention relates to the field of mechanical equipment, and more specifically to an assembly system for a drain valve. Background Technology

[0002] Traditionally, cylindrical drain valves require manual production and assembly, which is not only inefficient but also results in inconsistent product quality, necessitating individual product quality inspections.

[0003] In the process of realizing this invention, the inventors discovered the following problems in the prior art: In the installation or use of existing equipment, the accessories are installed one by one into the main body of the cylinder. This not only lengthens the production line and increases the space required for the arrangement or installation of the equipment, but also increases the assembly sequence and requirements of the machinery, leading to increased production difficulty and increased production costs. Summary of the Invention

[0004] The purpose of this invention is to provide an assembly system for drain valves, which aims to improve the problem of increased production costs caused by the large space occupancy or high difficulty in assembling existing cylindrical drain valves.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an assembly system for a drain valve, comprising a conveyor belt and a plurality of feeding devices for conveying accessories to the cylinder body arranged sequentially along the conveying direction of the conveyor belt, and an assembly device for assembling the conveyed accessories onto the cylinder body. At least one of the feeding devices is provided on the processing station of the assembly apparatus to feed materials, forming an assembly station with a plurality of assembly nodes; A feeding station is provided at the starting end of the conveyor belt. The feeding device and the assembly device are located on the same side of the conveyor belt. The other side of the conveyor belt forms a space area for personnel to inquire and / or maintain equipment and / or walk.

[0006] As a preferred structure of the present invention, a transplanting mechanism for reciprocating transplanting of the cylinder body is provided between the assembly station and the conveyor belt.

[0007] As a preferred structure of the present invention, the transplanting mechanism is a reciprocating walking mechanism, a mechanical gripper mechanism, or a workstation turntable mechanism.

[0008] As a preferred structure of the present invention, an independent positioning sensor is provided between the assembly devices, and a first detector is provided to detect whether the cylinder body product output from the previous station has completed the process.

[0009] As a preferred structure of the present invention, the assembly station is provided with a turntable mechanism for simultaneously installing different cylinder components at multiple stations, and a second detector for detecting whether the cylinder product has completed the process is provided between adjacent stations on the turntable mechanism or at the last station.

[0010] As a preferred structure of the present invention, at least one of the workstations of the turntable mechanism is a first adjustment mechanism for adjusting or maintaining the shape of the cylinder.

[0011] As a preferred structure of the present invention, the conveyor belt is provided with a second adjustment mechanism for adjusting the shape of the cylinder.

[0012] As a preferred structure of the present invention, the assembly device is provided in five groups, which are arranged along the conveying direction of the conveyor belt and are, in sequence, a robotic arm mechanism for installing connecting rods on the cylinder body, a cylinder cover assembly mechanism for installing cylinder cover on the cylinder body, a first cylinder bottom assembly mechanism for installing a first cylinder bottom on the cylinder body, an accessory assembly mechanism for installing accessories on the cylinder body, and a second cylinder bottom assembly mechanism for installing a second cylinder bottom on the cylinder body.

[0013] As a preferred embodiment of the present invention, the second cylinder bottom assembly mechanism is provided with a feeding conveyor belt for conveying to the accessory assembly mechanism, which is used to transport the assembled second cylinder bottom to the turntable mechanism of the accessory assembly mechanism for assembly.

[0014] As a preferred embodiment of the present invention, the turntable mechanism of the accessory assembly mechanism is provided with a transfer mechanism for outputting the assembled cylinder body.

[0015] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: 1. This invention employs an assembly line approach, and product parts that can be pre-assembled into components can be assembled using a turntable. This reduces assembly time on the assembly line and the space occupied by the equipment, thus forming an efficient assembly process that significantly improves product production efficiency. At the same time, it allows for a more rational layout of equipment positions. Specifically, the assembly frequency of the turntable mechanism is set to be the same as or close to the frequency at which the cylinder of the drain valve is conveyed to the corresponding processing station on the conveyor belt. This greatly reduces waiting time during the assembly process, lowers the overall production line footprint and installation complexity, and reduces equipment operating costs and maintenance difficulty.

[0016] 2. The present invention features a dedicated carrier plate design. Based on the product's outline, a cylindrical body is designed that can be placed or removed vertically to fix and limit the cylindrical body, and to facilitate the installation of corresponding drain valve components or accessories from top to bottom. This ensures the stability and precise positioning of the cylindrical body during assembly, enabling equidistant conveying and achieving an intermittent, continuous assembly effect.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] Additionally, it should be noted that the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" are all based on the orientation or positional relationship shown in the accompanying drawings. They are merely for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element of the present invention must have a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0022] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] like Figure 1 , Figure 8 and Figure 9As shown, the cylinder body 13 in this embodiment is a cylindrical drain valve structure, which includes the cylinder itself and components to be installed inside and outside the cylinder, including: connecting rod 1, cylinder cover 2, scale 3, connecting piece 4, inner cylinder bottom 5, float 6, cylinder core column 7, adjusting card 8, outer cylinder bottom 9, sealing piece 11, and water sealing piece 12. After assembly, a complete cylindrical drain valve product is obtained. Each component is automatically fed (e.g., by a vibratory feeder or conveyor belt) so that it can be automatically installed at the corresponding work station. Thus, the following components are formed: connecting rod vibratory feeder 201, cylinder cover vibratory feeder 202, scale vibratory feeder 203, connecting piece vibratory feeder 204, inner cylinder bottom vibratory feeder 205, float vibratory feeder 206, cylinder core column vibratory feeder 207, adjusting card vibratory feeder 208, outer cylinder bottom vibratory feeder 209, sealing piece vibratory feeder 210, and water sealing piece vibratory feeder 211. The feeding devices 20 and the assembly devices 30 are arranged along the conveyor belt 10 to form a continuous production line, achieving high-efficiency production.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this embodiment provides an assembly system for a drain valve, including a conveyor belt 10 and a plurality of feeding devices 20 arranged sequentially along the conveying direction of the conveyor belt 10 for conveying parts to a cylinder 13, and an assembly device 30 for assembling the conveyed parts onto the cylinder 13; at least one feeding device 20 is provided at the processing position of an assembly device 30 for feeding materials, forming an assembly station 40 with a plurality of assembly nodes; a loading station 101 is provided at the starting end of the conveyor belt 10, and the feeding devices 20 and the assembly device 30 are arranged on the same side of the conveyor belt 10.

[0025] In this embodiment, the feeding device 20 can be a vibratory feeder, a linear feeder, or a robotic arm, etc., to convey the cylinder body 13 components one by one. The assembly device 30 can be a robotic arm, a gripper cylinder, or a linear pusher power mechanism, etc. The linear pusher power mechanism can be a cylinder, a hydraulic cylinder, or a linear motor, etc., and a corresponding push plate is provided at the end of the power output shaft to accurately press or insert the parts into the corresponding positions of the cylinder body 13, so as to achieve stable assembly.

[0026] When using, such as Figure 1As shown, at the loading station 101 at the beginning of the conveyor belt 10, the cylinder body 13 to be assembled is placed in the carrier tray on the conveyor belt 10. The carrier tray has a placement groove to position and limit the cylinder body 13. When it is conveyed to the first assembly station 40, the connecting rod 1 can be picked up from the output end of the feeding device 20 (e.g., vibratory feeder) by a robot arm and accurately inserted into the slot inside the cylinder body 13 on the conveyor belt 10 to complete the assembly of the connecting rod 1.

[0027] like Figure 3 As shown, the conveyor belt 10 then transports the components to the next assembly station 40. At the second assembly station 40, the cylinder cover 2, ruler 3, and connecting piece 4 are assembled via a turntable mechanism 402. This turntable mechanism 402 enables simultaneous assembly at multiple stations, allowing the three components to rotate sequentially to their corresponding assembly positions under its drive, facilitating assembly with the assistance of a robotic arm. The assembled cylinder cover 2 component is then transported via a robotic arm, a traveling mechanism, or a conveyor belt. A pneumatic gripper and cylinder work together to install the cylinder cover 2 component onto the upper opening of the cylinder body 13 for pressing assembly. A camera or photoelectric sensor detects whether the cylinder cover 2 is fully pressed in place, ensuring proper sealing.

[0028] like Figure 4 As shown, the conveyor belt 10 then transports the material to the next assembly station 40. In the third assembly station 40, the inner cylinder bottom 5 and the float 6 can also be assembled using the turntable mechanism 402 to obtain the inner cylinder bottom 5 assembly with the float 6 inserted. At this station, the previous cylinder body 13 needs to be rotated 180° to facilitate the assembly operation of the bottom of the cylinder body 13 in subsequent stations. At the same time, the cylinder body 13 is inspected to determine whether there is a cylinder body 13 to be assembled on the conveyor belt 10 and whether the cylinder body 13 has completed the previous assembly process. If the inspection result is negative, the defective cylinder body 13 is removed from the production line by a rejection mechanism (e.g., an ejector cylinder). Then, the cylinder body 13 is transported by a robot, a traveling mechanism, or a conveyor belt, and then the cylinder cover 2 assembly is installed at the upper opening of the cylinder body 13 by pneumatic grippers and cylinders for pressing assembly. The camera or photoelectric sensor is used to detect whether the cylinder cover 2 is fully pressed to ensure that the pressing is in place.

[0029] like Figure 5 , Figure 6 and Figure 7As shown, the conveyor belt 10 then transports the material to the next assembly station 40. Assembly can also be performed using the turntable mechanism 402 at the fourth assembly station 40. Specifically, the cylinder body 13 is transferred to the turntable mechanism 402 via grippers and a traveling mechanism. Then, the cylinder core 7 is transported to the assembly station of the turntable mechanism 402 via the feeding device 20. A robotic arm or a pusher cylinder inserts the cylinder core 7 into the pre-assembled cylinder body 13. A station for installing adjustment cards 8 (used as switch levers) is provided at the assembly station of the turntable mechanism 402. The adjustment cards 8 are transported via a vibratory feeder (i.e., the feeding device 20), thus enabling the positioning and installation of the adjustment cards 8 to be completed sequentially at different stations of the turntable mechanism 402. Furthermore, the turntable mechanism 402 is equipped with a station for assembling the outer cylinder bottom 9 component. The cylinder body 13 is clamped by grippers or symmetrical cylinders so that the outer cylinder bottom 9 component can be pressed into or installed onto the cylinder body 13, completing the final assembly process. Finally, the finished product drain valve is transferred to the conveyor belt 10 or the finished product unloading area by grippers or a 180-degree rotating station, completing the entire automated assembly process.

[0030] Among them, such as Figure 6 As shown, the outer cylinder bottom 9 component is assembled from an outer bottom plate, a silicone sheet, and a water-sealing sheet 12. It can also be fed sequentially by a vibratory feeder or by a robotic arm (for the silicone sheet, a robotic arm is required to grasp it). The turntable mechanism 402 is used for multi-station synchronous assembly: first, the gripper positions the outer bottom plate to the turntable station, then the pneumatic pressure head precisely presses the silicone sheet into its groove, and then the vision-guided robotic arm picks up the water-sealing sheet 12 to complete the final stacking assembly, ensuring that the materials of each layer are accurately aligned to form a sealed assembly structure, effectively preventing leakage.

[0031] In this embodiment, a transfer mechanism 401 for reciprocating transfer of cylinder body 13 is provided between the assembly station 40 and the conveyor belt 10. For example, the transfer mechanism 401 is a reciprocating walking mechanism, a mechanical gripper mechanism, or a station turntable mechanism 402. The station turntable mechanism 402 has a groove for placing cylinder body 13, or a pneumatic gripper or a clamping cylinder on its station to achieve stable rotational conveying so as to transfer cylinder body 13 or cylinder body 13 components. This allows the installed robot or pressing mechanism to apply force precisely to the designated assembly position, ensuring production efficiency.

[0032] In this embodiment, each assembly device 30 is independently equipped with a position sensor 301 and a first detector 302 for detecting whether the cylinder body 13 product output from the previous station has completed the process. The position sensor 301 can be a photoelectric sensor, a proximity switch, or a laser sensor. The photoelectric sensor can be an E3Z-D61 type sensor, used to monitor in real time whether the cylinder body 13 has accurately reached the preset position. The first detector 302 can be a visual recognition camera or a pressure sensing detector. The pressure detector can be an XK-3120T pressure detector, used to determine whether the cylinder body 13 has completed the pressing or assembly action at the previous station, ensuring no omissions or misassemblies.

[0033] Thus, the positioning sensor 301 can detect whether the cylinder body 13 on the conveyor belt 10 is accurately delivered to the assembly station, achieving the purpose of orderly material supply. For example, the cylinder body 13 can be intermittently conveyed so that it can be assembled on the conveyor belt 10, or it can be easily grasped and assembled by the robot arm. This avoids assembly deviations caused by misalignment of the work station or incomplete process, improves the accuracy and stability of assembly, and ensures that the assembly quality of each drain valve meets the standards.

[0034] In this embodiment, the assembly station 40 is equipped with a turntable mechanism 402 for simultaneously installing different cylinder body 13 components at multiple stations. A second detector 4021 is provided between adjacent stations on the turntable mechanism 402 or at the last station to detect whether the cylinder body 13 product has completed the process. The second detector 4021 can be a high-precision visual recognition industrial camera, used to capture the assembly posture, positional offset, and sealing surface fit of the cylinder body 13 components in real time, so as to ensure that the products entering the next process for assembly are products that have completed qualified assembly in the previous process, thus ensuring the quality of production.

[0035] Specifically, the turntable is equipped with multiple workstations as needed to achieve efficient collaborative assembly of multiple processes simultaneously, significantly improving production cycle time and overall equipment efficiency, while reducing the frequency of manual intervention and assembly errors. The turntable mechanism 402 consists of the turntable and the servo motor that drives its rotation. Each workstation on the turntable is equipped with positioning fixtures (such as placement slots adapted to the product; pneumatic or mechanical grippers; or protrusions that engage with the product, etc.) to precisely fix the parts to be assembled, ensuring positional accuracy and repeatability during the assembly process.

[0036] Furthermore, such as Figure 5As shown, at least one of the workstations of the turntable mechanism 402 in this embodiment is a first adjustment mechanism 4022 for adjusting or holding the shape of the cylinder 13. Specifically, the first adjustment mechanism 4022 can be a mechanical gripper for flipping or tilting the cylinder 13, or a pneumatic gripper for clamping and fixing the cylinder 13, or a clamp with multiple cylinders or hydraulic cylinders to clamp and fix the cylinder 13 symmetrically. It can also be used in conjunction with a placement platform for positioning and placing the cylinder 13 to ensure that the cylinder 13 maintains a stable posture during assembly and avoids displacement or overturning due to the rotation of the turntable.

[0037] In this embodiment, the conveyor belt 10 is provided with a second adjustment mechanism 102 for adjusting the shape of the cylinder 13. The second adjustment mechanism 102 has the same structure or device design as the first adjustment mechanism 4022, and can be referred to the description of the first adjustment mechanism 4022, so it will not be repeated here.

[0038] like Figure 1 As shown, in this embodiment, the assembly device 30 is provided with five sets. The five sets of assembly devices 30 are arranged along the conveying direction of the conveyor belt 10, and are in sequence as follows: a robotic arm mechanism 31 for installing the connecting rod 1 on the cylinder body 13, a cylinder cover assembly mechanism 32 for installing the cylinder cover 2 on the cylinder body 13, a first cylinder bottom assembly mechanism 33 for installing the first cylinder bottom on the cylinder body 13, an accessory assembly mechanism 34 for installing accessories on the cylinder body 13, and a second cylinder bottom assembly mechanism 35 for installing the second cylinder bottom on the cylinder body 13.

[0039] like Figures 1 to 7 As shown, this embodiment assembles the drain valve into six main parts: cylinder body 13, connecting rod 1, cylinder cover assembly, inner cylinder bottom assembly, outer cylinder bottom assembly, and cylinder core column assembly. The cylinder body 13 serves as the main structure of the drain valve, bearing the installation and positioning of the other components. The connecting rod 1 only needs to be installed into the cylinder body 13 via a robotic arm mechanism 31 to complete its positioning and fixation. The cylinder cover assembly 2, inner cylinder bottom assembly, and outer cylinder bottom assembly require initial assembly via a turntable mechanism 402, followed by final assembly via a second adjusting mechanism 102.

[0040] Specifically, the cap assembly mechanism 32 includes three vibrating conveyor plates for the cap 2, scale 3, and connecting piece 4, as well as a turntable mechanism 402 for assembly. The workstations on the turntable mechanism 402 include an assembly station 40 for inserting the scale 3 with grippers, an assembly station 40 for clamping the connecting piece 4 into the cap 2 with grippers, and a detection station for confirming the positional accuracy of the components through a vision positioning system. If the result is unsuitable, the components are separated by a push cylinder or mechanical gripper. Defective products are rejected and sent to the recycling channel, while qualified products enter the next assembly process with the turntable. This completes the assembly of the cap components for use, so that they can be output through the aforementioned transfer mechanism 401, where they are precisely grasped and assembled by the assembly robot.

[0041] Subsequently, the first cylinder bottom assembly mechanism 33 includes two vibrating conveyor discs for the inner cylinder bottom 5 and the float 6, as well as corresponding conveyor belts. The float 6 is inserted into the groove on the inner cylinder cover 2 by mechanical grippers to complete the assembly. Then, the assembled inner cylinder bottom 5 component is transferred to the conveyor belt 10 by another mechanical gripper and installed into the cylinder body 13 to be assembled on the conveyor belt 10, thus completing the precise embedding of the inner cylinder bottom 5 component.

[0042] The second cylinder bottom assembly mechanism 35 includes an outer cylinder bottom 9, a sealing sheet 11, and a water-sealing sheet 12. The sealing sheet 11 is a silicone sheet with a circular structure, used to assemble on the bottom surface of the outer cylinder bottom 9 for sealing purposes. The outer cylinder bottom 9 and the water-sealing sheet 12 can be conveyed using a vibratory feeder, while the sealing sheet 11 can be stacked using columns, or multiple columns for placing the sealing sheet 11 can be set on a turntable to increase the supply of the sealing sheet 11. The second cylinder bottom assembly mechanism 35 has multiple stations with a turntable mechanism 402 for assembly. Specifically, the turntable has a boss for placing the outer cylinder bottom 9, and the boss has a groove for fixing the outer cylinder bottom 9, so that the surface of the outer cylinder bottom 9 to be assembled faces upward and can be stably fixed in the groove for assembly. Then, the sealing sheet 11 is picked up by a vacuum suction cup or mechanical gripper and accurately placed on the surface of the outer cylinder bottom 9 to be assembled, ensuring that the sealing sheet 11 and the outer cylinder bottom 9 are completely fitted without deviation. Subsequently, the sealing plate 12 is picked up by another mechanical gripper or vacuum suction cup. The vacuum suction cup needs to be driven by a reciprocating cylinder to accurately press the sealing plate 12 onto the sealing plate 11, completing the assembly of the outer cylinder bottom 9 and obtaining the outer cylinder bottom 9 assembly. Finally, it is installed onto the cylinder body 13 by a robotic arm to complete the final assembly.

[0043] Before assembling the outer cylinder bottom 9 component, the cylinder body 13 needs to be assembled with the cylinder core 7 and the adjusting card 8. Specifically, the component assembly mechanism 34 has a vibratory feeder for feeding the cylinder core 7 and the adjusting card 8, and a turntable mechanism 402 for assembly. The turntable has multiple stations, and each station has a positioning groove for placing the cylinder body 13, so that the robot arm can transfer the cylinder body 13 to be assembled from the conveyor belt 10 and accurately place it into the groove. At the cylinder core 7 assembly station 40, the mechanical gripper picks up the cylinder core 7 and inserts it into the cylinder body 13. At the adjusting card 8 assembly station 40, the mechanical gripper picks up the adjusting card 8 from the vibratory feeder outlet and engages it in the designated slot on the outer wall of the cylinder body 13, thus completing the assembly of the two components of the cylinder body 13.

[0044] In this embodiment, the second cylinder bottom assembly mechanism 35 is provided with a feeding conveyor belt 351 for conveying to the accessory assembly mechanism 34. This conveyor belt 351 transports the assembled second cylinder bottom to the turntable mechanism 402 of the accessory assembly mechanism 34 for assembly. Thus, there is no need to increase the length of the conveyor belt 10, which minimizes the length of the conveyor belt 10, thereby saving equipment space and reducing energy consumption.

[0045] Furthermore, in this embodiment, a transfer mechanism 341 for outputting the assembled cylinder body 13 is provided on the turntable mechanism 402 of the accessory assembly mechanism 34. The transfer mechanism 341 can be a conveyor belt, mechanical gripper, slide rail channel or push cylinder, etc., for outputting the assembled drain valve for subsequent testing or packaging.

[0046] In the above-described configuration, the conveyor belt 10 serves as the main layout line, with all the feeding devices 20 and assembly devices 30 positioned on one side of the conveyor belt 10. The other side is reserved for personnel to monitor equipment operation or perform maintenance, facilitating timely detection and handling of any abnormalities. Simultaneously, the assembly devices 30 and feeding devices 20 located on the same side can form a phased regional layout, concentrating assemblies that can be assembled together in the same area. This reduces material handling distances, avoids arranging assembly one by one, lowers assembly difficulty, and reduces the length of the conveyor belt 10, thereby improving assembly efficiency and space utilization. The coordinated operation between the devices is uniformly scheduled through the control system, ensuring smooth operation and synchronized cycles, further enhancing production automation and operational stability.

[0047] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
