Description

Technical Field

[0001] This utility model relates to the field of automatic assembly technology of self-priming pump check valves, specifically an automatic assembly line for self-priming pump check valves. Background Technology

[0002] The self-priming pump check valve is a key component ensuring the stable operation of fluid equipment. The assembly quality of its filter element assembly directly affects the check valve's sealing performance, service life, and fluid control accuracy. In the industrial manufacturing sector, with the continuous growth in market demand for self-priming pumps, the traditional self-priming pump check valve filter element assembly operation mode is gradually becoming unable to meet the requirements of modern production.

[0003] Currently, the industry commonly uses manual assembly to complete the assembly of self-priming pump check valve filter elements. This assembly method has many drawbacks. First, the assembly process is highly dependent on manual operation. From the positioning of the screw and spring to the combination of the frame, nut, washer, and bolt, each step requires workers to rely on experience and skill. Because manual operation cannot guarantee absolute consistency and precision, the product assembly quality is inconsistent, with a defect rate as high as 3%-5%. This not only increases after-sales maintenance costs but also affects the company's brand reputation.

[0004] Secondly, manual assembly is extremely inefficient. The traditional assembly process involves three steps, requiring three operators to work together, and each product takes 40-60 seconds to assemble. Under the demands of large-scale production, this inefficient assembly model severely restricts capacity expansion and makes it difficult to meet the market's requirements for rapid delivery. At the same time, the large investment of human resources keeps labor costs high. With labor costs rising year by year, companies not only need to pay high wages and benefits but also face hidden costs such as personnel management and training, further increasing production costs and reducing their competitiveness in the market.

[0005] Furthermore, manual assembly methods suffer from high labor intensity and poor working conditions. Prolonged, repetitive assembly work easily leads to worker fatigue, resulting in operational errors and increased safety hazards. Moreover, the metal shavings, dust, and other pollutants generated during assembly also pose potential threats to workers' health. With the rapid development of industrial automation technology, traditional manual assembly methods are no longer suitable for the development trend of intelligent manufacturing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-5 This utility model provides a technical solution:

A mounting spindle 11 is located below the rolling wheel 1. The rolling wheel 1 and the mounting spindle 11 are coaxial and rotatably connected. A first gear 13 is coaxially fixedly connected to the rolling wheel 1. Of the six circumferentially symmetrically distributed assembly stations 10, five of them are used to load the self-priming pump check valve assembly. After the final loading is completed, the assembly is performed. The remaining assembly station 10 is used to assist in unloading.

[0039] Vibratory plate 2 is a flat circular disc structure. Vibratory plate 2 is set above rolling disc 1 and is at a fixed tilt angle to rolling disc 1.

The material guide rods 14 are used to assist the screw spring assembly in the screw spring assembly 8 to separate and limit the material so that it can be accurately output to the assembly station 10.

[0040] Nut feeding assembly 3 is a grooved sliding track. Nut feeding assembly 3 is located on one side of the rolling wheel 1. The output end of nut feeding assembly 3 faces a set of assembly stations 10. Nut feeding assembly 3 transports multiple sets of nuts arranged at equal intervals. The nuts are first fed into the assembly station 10, and then the assembly station 10 with nuts rotates with the rolling wheel 1.

[0041] The gasket feeding assembly 4 is a grooved sliding track. The gasket feeding assembly 4 is located on one side of the rolling wheel 1. The output end of the gasket feeding assembly 4 faces a set of assembly stations 10. Multiple sets of equidistantly arranged gaskets are transported on the gasket feeding assembly 4. When the assembly station 10 with nuts rotates with the rolling wheel 1 to the output end of the gasket feeding assembly 4, the gasket feeding assembly 4 just outputs a set of gaskets. After that, the assembly station 10 with nuts and gaskets will continue to rotate with the rolling wheel 1.

[0042] Nut feeding assembly 5 is a grooved sliding track. Nut feeding assembly 5 is located on one side of the rolling disc 1. The output end of nut feeding assembly 5 is directly opposite a set of assembly stations 10. Nut feeding assembly 5 transports multiple sets of nuts arranged at equal intervals. When the assembly station 10 with nuts and washers rotates with the rolling disc 1 to the output end of nut feeding assembly 5, nut feeding assembly 5 just outputs a set of nuts. After that, assembly station 10 with nuts, washers and nuts will continue to rotate with the rolling disc 1.

[0043] The skeleton feeding assembly 6 is a grooved sliding track, which is located on one side of the rolling wheel 1. The output end of the skeleton feeding assembly 6 is directly opposite a set of assembly stations 10. Multiple sets of skeletons are transported on the skeleton feeding assembly 6. When the assembly station 10 with nuts, washers and nuts rotates with the rolling wheel 1 to the output end of the skeleton feeding assembly 6, the skeleton feeding assembly 6 just outputs a set of skeletons. After that, the assembly station 10 with nuts, washers and nuts and skeletons will continue to rotate with the rolling wheel 1.

[0044] Spring feeding assembly 7 is a belt-type rolling conveyor device, on which multiple sets of equidistantly arranged springs are transported.

[0045] The screw-spring combination feeding assembly 8 includes an inclined sliding rail 22, a buffer connecting rail 23, and a semi-circular spiral trajectory slide rail 24. The inclined sliding rail 22 is located directly above the spring feeding assembly 7, and multiple sets of equally spaced screws slide on the inclined sliding rail 22. The buffer connecting rail 23 is located at the end of the inclined sliding rail 22, and multiple sets of screw-spring combinations slide on the buffer connecting rail 23. The semi-circular spiral trajectory slide rail 24 is located at the end of the buffer connecting rail 23, and is located outside the vibrating plate 2. Multiple sets of material guide rods 14 are placed above the semi-circular spiral trajectory slide rail 24, and the output end of the semi-circular spiral trajectory slide rail 24 faces a set of... Assembly station 10: The screw and spring are initially joined by the screw and spring assembly feeding component 8. When the assembly station 10, which includes the nut, washer, and skeleton, rotates with the rolling wheel 1 to the output end of the semi-circular spiral track slide rail 24, the material guide rod 14 on the vibrating plate 2 is simultaneously rotating due to the rotation of the rolling wheel 1 driven by the vibrating plate 2. The material guide rod 14 rotates and disengages from the semi-circular spiral track slide rail 24. A set of screw and spring assemblies on the semi-circular spiral track slide rail 24 will slide and fall into the assembly station 10, and the screw and spring assemblies will fall directly above multiple sets of parts in the assembly station 10. At this time, the screw is driven to rotate by the automatic screw machine 9, and the screw will complete the threaded connection with the nut and the screw.

[0046] Automatic screw machine 9 is positioned directly above a set of assembly stations 10. The end of automatic screw machine 9 has a mating port corresponding to the screw rod. Automatic screw machine 9 can drive the screw rod to rotate, completing the threaded connection. It can assemble all the parts at assembly station 10 into a self-priming pump check valve. After assembly, the self-priming pump check valve moves to the gap as assembly station 1 rotates, and is finally unloaded by the unloading mechanism.

The vibratory feeder 2 is connected to the power mechanism via the rotating spindle 16 and the spindle gear 17. The power mechanism provides power to drive the vibratory feeder 2 to rotate through the rotating spindle 16 and the spindle gear 17. Since the second gear 15 and the first gear 13 below the vibratory feeder 2 are meshed, the rotation of the vibratory feeder 2 will drive the rolling wheel 1 to rotate. The rotation of the rolling wheel 1 will cause the six sets of assembly stations 10 to rotate, completing the transfer of materials.

[0050] Furthermore, the bottom of the track of the nut feeding assembly 3 is provided with a nut head clearance groove 18 corresponding to the nut.

[0051] Furthermore, the horizontal height of the output ends of the nut feeding assembly 3, gasket feeding assembly 4, nut feeding assembly 5, and skeleton feeding assembly 6 increases sequentially. This design, based on the structure of the self-priming pump check valve, ensures that each part is in the correct position, and the feeding sequence is from bottom to top. The nut of the self-priming pump check valve is at the bottom, above it is the gasket, then the nut, above the nut is the skeleton, and at the very top are the spring and the screw.

[0052] Furthermore, the spring feeding assembly 7 includes two sets of rotating rollers 19 and a conveyor belt 20. The conveyor belt 20 is fitted onto the two sets of rotating rollers 19, and multiple sets of equidistant spring grooves 21 are formed on the conveyor belt 20. The spring grooves 21 can ensure accurate spring positioning, which facilitates the initial connection of the screw and the spring.

[0076] Inclined sliding track 22: A component of the screw-spring combination feeding assembly 8, located directly above the spring feeding assembly 7, used to slide the transport screw to the buffer connecting track 23;

[0077] Buffer connecting rail 23: A component of the screw-spring combination feeding assembly 8, connecting the inclined sliding rail 22 and the semi-circular spiral trajectory rail 24, with a spring anti-disengagement support rail 25 below, used for the initial connection of the screw and spring and buffer transmission;

[0078] Semi-circular spiral trajectory guide rail 24: a component of the screw spring assembly feeding component 8, located outside the vibrating plate 2, with the output end facing the assembly station 10. It has a material guide rod 14 above and a spring anti-detachment support guide rail 25 below, used to accurately output the screw spring assembly to the assembly station 10.

[0079] Spring anti-disengagement support rail 25: Located below the buffer connecting rail 23 and the semi-circular spiral trajectory slide rail 24, it is used to prevent the screw from separating from the spring assembly and ensure transmission stability.

[0080] Working principle: After the power mechanism is started, the main shaft 16 and the main shaft gear 17 drive the vibratory plate 2 to start rotating. Since the second gear 15 below the vibratory plate 2 meshes with the first gear 13 on the rolling wheel 1, the rotation of the vibratory plate 2 will drive the rolling wheel 1 to rotate synchronously, thereby causing the six sets of assembly stations 10 on the rolling wheel 1 to start cyclical movement. In the component conveying stage, each feeding component operates in an orderly manner. The nut feeding component 3 serves as the starting station, using a grooved sliding track to sequentially convey equidistant nuts to the assembly station 10 of the rolling wheel 1. At this time, the nut head is precisely positioned by the nut head clearance groove 18 at the bottom of the track. As the rolling wheel 1 rotates, the assembly station 10 with nuts passes sequentially through the gasket feeding component 4, the nut feeding component 5, and the skeleton feeding component 6. As the output heights of these four feeding components rise sequentially and match the structure of the self-priming pump check valve, when assembly station 10 rotates to the corresponding position, the gasket, nut, and frame will fall precisely into their designated positions within assembly station 10 via their respective grooved sliding tracks, in a bottom-to-top order. Simultaneously, spring feeding assembly 7 utilizes two sets of rotating rollers 19 and a conveyor belt 20 to position and transport equidistantly arranged springs via spring grooves 21 on the conveyor belt 20. When the springs are conveyed directly below the inclined sliding track 22, they initially combine with the screw sliding down from the inclined sliding track 22 at the buffer connecting track 23, forming a screw-spring assembly. The assembly slides along the buffer connecting track 23 to the semi-circular spiral trajectory slide rail 24, at which point the material guide rod 14 on the vibrating plate 2 rotates synchronously with the vibrating plate 2. When assembly station 10, equipped with nuts, washers, nuts, and a frame, rotates to the output end of the semi-circular spiral track slide rail 24, the material guide rod 14 rotates and disengages from the semi-circular spiral track slide rail 24. This causes a set of screw-spring couplings on the semi-circular spiral track slide rail 24 to slide down into assembly station 10 under gravity, landing precisely above other components. Then, the mating port at the end of the automatic screw machine 9 precisely aligns with the screw. The automatic screw machine 9 starts, driving the screw to rotate and tightly connecting the screw with the nut and cap via threaded connections. Simultaneously, it assembles all components, including springs, washers, and frames, into a complete self-priming pump check valve. Assembly station 10 employs a semi-enclosed mold cavity structure corresponding to the self-priming pump check valve, which not only allows for precise positioning of each component but also provides stable support during assembly. After assembly, the self-priming pump check valve continues to rotate with the rolling wheel 1. When it reaches the gap at the unloading station, the unloading mechanism removes the finished product, completing the entire assembly process. The mounting thread 12 on the mounting spindle 11 secures the roller disc 1 through a threaded connection, providing stable support. Furthermore, the buffer connecting rail 23 and the spring anti-disengagement support rail 25 below the semi-circular spiral trajectory slide rail 24 effectively prevent the screw and spring from separating during transmission, ensuring the continuity and stability of the assembly process.Throughout the assembly process, the conveying time of each component, the rotation speed of the rolling wheel 1, and the starting timing of the automatic screw machine 9 are all precisely calculated and adjusted to ensure that all parts can reach the designated assembly position at the same time, achieving one-time assembly and forming. This greatly improves the assembly efficiency and quality of the self-priming pump check valve and reduces production costs and manpower input.
