Description

Technical Field

[0001] This invention relates to the field of valve optical inspection and conveying technology, and in particular to a follow-up conveying and inspection device for vertical check valves. Background Technology

[0002] Vertical check valves are core control components in fluid transport systems such as water supply and drainage, chemical, and petroleum industries. They are primarily used to achieve unidirectional flow by relying on the weight of the medium and fluid pressure, effectively preventing backflow and ensuring the stable and safe operation of the pipeline system. The machining precision of the valve's internal structure directly determines its sealing performance, opening and closing sensitivity, and service life. Therefore, during the production process, it is essential to conduct precise inspections on key components such as the valve's internal cavity, sealing surface, and mating structure to eliminate unqualified products and ensure the quality of valves leaving the factory.

[0003] Currently, the internal precision testing of vertical check valves in the industry generally adopts a fixed-position testing method, which relies on fixed-installation testing equipment to complete the fixed-point testing operation. This testing mode has a fixed equipment structure and fixed testing position, and can only perform sampling inspections on valves in a single position and a fixed batch. It cannot adapt to the continuous production rhythm of the assembly line and cannot achieve full-coverage continuous testing of all valves leaving the factory. Existing testing technologies have obvious technical defects. The testing process requires manual assistance for loading and unloading, alignment and calibration, which is cumbersome and has extremely low overall testing efficiency, making it unsuitable for the needs of large-scale mass production. At the same time, the limitations of manual intervention and fixed-point testing are prone to testing blind spots and missed detections, resulting in poor testing accuracy stability. Moreover, the labor and equipment maintenance costs are high, significantly increasing the overall production cost of valves and restricting the industry's development needs for high-precision, mass production, and low-cost production of vertical check valves. Summary of the Invention

[0004] The technical problem this invention aims to solve is that existing vertical check valve internal precision testing methods mostly adopt fixed-position testing, with a solidified equipment structure and fixed testing position. This method can only perform sampling inspections on valves in a single position and a fixed batch, which cannot adapt to the continuous production rhythm of assembly lines and makes it difficult to achieve full coverage continuous testing of all valves leaving the factory. The testing process requires manual assistance for loading and unloading, alignment and calibration, which is cumbersome and has extremely low overall testing efficiency. Furthermore, the limitations of manual intervention and fixed-point testing can easily lead to blind spots and missed detections, resulting in poor testing accuracy stability and high labor and equipment maintenance costs.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a follow-up material conveying and detection device for a vertical check valve, including a horizontal main frame and an electrically controlled conveying belt for conveying the vertical check valve. A top-mounted circulating guide rail is fixedly installed on the upper end of the horizontal main frame through an upper frame. A plurality of top-mounted lifting seats are movably assembled on the lower end of the top-mounted circulating guide rail. A bottom correction guide seat is installed below the top-mounted lifting seat through an external rope. An electrically controlled lifting optical detection column is installed inside the bottom correction guide seat.

[0006] Furthermore, a side guide frame for guiding the vertical check valve is fixedly installed on the inner side of the upper frame.

[0007] Furthermore, the top-mounted lifting base includes a top drive base, a top side moving wheel assembly mounted on the top drive base, a bottom lifting base mounted at the lower end of the top drive base, an electrically controlled winch mounted inside the bottom lifting base, a bottom correction guide mounted at the lower end of the external winch rope of the electrically controlled winch, an electrically controlled lifting optical detection column mounted inside the bottom correction guide, and a plurality of electrically controlled correction arms mounted outside the bottom correction guide.

[0008] Furthermore, the top drive seat is inserted into the top circulating guide rail via the top side moving wheel set and is movably assembled with the top circulating guide rail. The top side moving wheel set drives the top drive seat to move and adjust along the top circulating guide rail by rotation.

[0009] Furthermore, a plurality of arc-shaped telescopic openings are provided on the outer arc-shaped surface of the bottom hoisting base to facilitate the winding and unwinding of the external rope of the electric winch. The external rope of the electric winch passes through the arc-shaped telescopic openings and connects to the upper surface of the bottom correction guide seat at the lower end.

[0010] Furthermore, the bottom correction guide seat has an internal guide hole with an opening at the lower end, and the outer arc-shaped surface of the bottom correction guide seat has an outwardly protruding lateral connecting bracket.

[0011] Furthermore, the electrically controlled lifting optical inspection column includes an electrically controlled lifting strut fixed to the top surface of the inner guide hole, an outer lifting sleeve fitted on the outside of the electrically controlled lifting strut, an electrically controlled rotating disk installed at the lower end of the outer lifting sleeve, and a plurality of optical inspection probes installed at the lower end of the electrically controlled rotating disk. The bottom protruding end of the electrically controlled lifting strut is fixedly connected to the inner bottom surface of the outer lifting sleeve.

[0012] Furthermore, the electrically controlled correction arm includes an arc-shaped correction claw arm hinged to a lateral connecting bracket and an external support rod for controlling the arc-shaped correction claw arm.

[0013] Furthermore, a motor level is installed on the upper surface of the bottom correction guide seat.

[0014] Furthermore, embedded pressure sensors are installed on the outer arc-shaped correction surface and the end of the arc-shaped correction claw arm.

[0015] The beneficial effects of this invention are as follows: Through the coordinated movement of the top-mounted circulating guide rail and the top-mounted hoisting seat, the electrically controlled lifting optical inspection column moves synchronously with the vertical check valve on the conveyor belt for inspection, eliminating the need for machine downtime and adapting to the continuous production rhythm of the assembly line. This achieves full-coverage continuous inspection of all valves leaving the factory, solving the technical problem that fixed-position inspection cannot adapt to assembly line production and can only perform random checks. Through the coordination of the electrically controlled winch lifting, the electrically controlled correction arm alignment correction, and the motor level calibration, the inspection process is automated, eliminating the need for manual assistance in loading / unloading and alignment calibration, significantly improving inspection efficiency and overcoming the defects of poor inspection accuracy stability and the tendency to produce blind spots and missed detections due to manual intervention. By extending the electrically controlled lifting optical inspection column into the valve's internal cavity for rotational scanning inspection, combined with the clamping force feedback from the embedded pressure sensor, high-precision, blind-spot-free inspection of the valve's internal cavity is achieved, reducing labor and equipment maintenance costs and meeting the industry's demand for high-precision, mass production, and low-cost production of vertical check valves.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a follow-up conveying and detection device for vertical check valves includes a horizontal main frame 100 and an electrically controlled conveyor belt 200 for conveying the vertical check valves. The horizontal main frame 100 serves as the supporting base for the entire device, and a top-mounted circulating guide rail 120 is fixedly installed on its upper end via an upper frame 110. The top-mounted circulating guide rail 120 is horizontally arranged above the electrically controlled conveyor belt 200. The electrically controlled conveyor belt 200 is driven by a stepper motor and is used to continuously convey the vertical check valves horizontally to the detection area. A side guide frame 130 for guiding the vertical check valves is fixedly installed on the inner side of the upper frame 110. The side guide frame 130 laterally limits the vertical check valves during the conveying process, ensuring that the valves pass through the detection area with a stable posture and position. The lower end of the top-mounted circulating guide rail 120 is movably equipped with a plurality of top-mounted lifting seats 210. The top-mounted lifting seats 210 can move horizontally along the top-mounted circulating guide rail 120 to drive the detection components to move synchronously with the valves on the conveyor belt.

[0023] The top-mounted lifting base 210 includes a top drive base 211, a top side moving wheel set 212, a bottom lifting base 213, and an electrically controlled winch 214. The top drive base 211 is inserted into the top-mounted circulating guide rail 120 via the top side moving wheel set 212 and is movably assembled with the top-mounted circulating guide rail 120. The top side moving wheel set 212 has a built-in drive motor, which drives the top drive base 211 to move and adjust along the top-mounted circulating guide rail 120 by rotation, thereby realizing the follow-up feeding of the detection component. The bottom lifting base 213 is fixedly installed at the lower end of the top drive base 211, and the electrically controlled winch 214 is installed inside the bottom lifting base 213 for winding and unwinding the external winch rope 230. The outer arc-shaped surface of the bottom hoisting base 213 is provided with a plurality of arc-shaped telescopic openings 215 for convenient winding and unwinding of the external rope 230. The external rope 230 of the electric winch 214 passes through the arc-shaped telescopic openings 215 and extends downwards to connect with the upper surface of the bottom correction guide seat 220 at the lower end. The lifting height of the bottom correction guide seat 220 is controlled by the winding and unwinding action of the electric winch 214.

[0024] The bottom correction guide seat 220 has an internal guide hole 221 with an opening at the lower end. The electrically controlled lifting optical detection column 300 is installed inside the internal guide hole 221 and can move up and down along the internal guide hole 221 and extend downward. The outer arc-shaped surface of the bottom correction guide seat 220 has an outwardly protruding lateral connecting bracket 222, and the electrically controlled correction arm 400 is hinged to the lateral connecting bracket 222. A motor level 223 is installed on the upper surface of the bottom correction guide seat 220. The motor level 223 is used to detect the horizontal attitude of the bottom correction guide seat 220 in real time and send the levelness signal to the controller. The controller controls the electrically controlled correction arm 400 to correct the attitude of the valve according to the levelness signal.

[0025] The electrically controlled lifting optical inspection column 300 includes an electrically controlled lifting strut 310, an external lifting sleeve 320, an electrically controlled rotating disk 330, and a plurality of optical inspection probes 340. The electrically controlled lifting strut 310 is fixed to the top surface inside the internal guide hole 221. The external lifting sleeve 320 is fitted onto the outside of the electrically controlled lifting strut 310, with its bottom protruding end fixedly connected to the bottom surface of the external lifting sleeve 320. The extension and retraction of the electrically controlled lifting strut 310 controls the up-and-down movement of the external lifting sleeve 320 along the internal guide hole 221. The electrically controlled rotating disk 330 is installed at the lower end of the external lifting sleeve 320 and is driven by a stepper motor, enabling the optical inspection probes 340 below it to rotate 360 ​​degrees in the horizontal plane. The optical inspection probe 340 uses a combination of optical imaging and laser ranging to perform rotational scanning inspection on key parts such as the internal cavity, sealing surface, and mating structure of the valve after it extends into the internal cavity of the vertical check valve. This allows it to obtain data on the internal cavity structure contour, aperture size, and internal wall surface quality, achieving all-round blind-spot-free inspection of the valve's internal cavity.

[0026] The electrically controlled correction arm 400 includes an arc-shaped correction claw arm 410 and an external support rod 420. The arc-shaped correction claw arm 410 is hinged to a lateral connecting bracket 222. The two ends of the external support rod 420 are connected to the lateral connecting bracket 222 and the arc-shaped correction claw arm 410, respectively. The opening and closing of the arc-shaped correction claw arm 410 is controlled by the extension and retraction of the external support rod 420, thereby correcting the alignment and attitude of the vertical check valve on the conveyor belt. Embedded pressure sensors 430 are installed on the outer arc-shaped correction surface and the end of the arc-shaped correction claw arm 410. The embedded pressure sensors 430 are used to detect the clamping pressure between the arc-shaped correction claw arm 410 and the valve in real time and send the pressure signal to the controller. The controller controls the extension and retraction of the external support rod 420 according to the pressure signal to avoid excessive clamping pressure that could damage the valve body or insufficient clamping pressure that could cause valve displacement.

[0027] The working process of this device is as follows: Before the testing operation begins, vertical check valves are placed sequentially on the electrically controlled conveyor belt 200, which continuously transports them to the testing area. The side guide frame 130 guides the valves laterally and adjusts their placement. When the valves enter the testing area, the positioning probe at the center of the bottom of the electrically controlled rotating disk 330 optically positions the valve port at the top. Then, the controller controls the top side moving wheel group 212 to rotate, driving the top transmission seat 211 to move horizontally along the top circulating guide rail 120, so that the top lifting seat 210 and the valve on the conveyor belt move synchronously. Subsequently, the electrically controlled winch 214 releases the rope, and the external winch 230 is lowered through the arc-shaped telescopic port 215, driving the bottom correction guide seat 220 to descend to the upper end of the valve. The motor level 223 monitors the horizontal posture of the bottom correction guide seat 220 in real time. The controller controls the extension and retraction of the external support rod 420 according to the horizontality signal, driving the arc-shaped correction claw arm 410 to rotate outward to align and correct the valve. The embedded pressure sensor 430 provides feedback on the clamping pressure to ensure accurate valve posture and uniform force. Then, the electrically controlled lifting support rod 310 extends, pushing the external lifting sleeve 320 downward along the internal guide hole 221, extending the electrically controlled rotating disk 330 and the optical detection probe 340 into the internal cavity of the vertical check valve. The electrically controlled rotating disk 330 drives the optical detection probe 340 to perform a 360-degree rotation scan in the valve cavity, comprehensively inspecting the internal cavity, sealing surface, and mating structure of the valve. After the inspection is completed, the electrically controlled lifting support rod 310 retracts to retract the optical inspection probe 340, the electrically controlled winch 214 winds up the rope to lift the bottom correction guide seat 220, and the top hoisting seat 210 returns to the starting position, waiting for the next valve to enter the inspection area. This achieves continuous, full-coverage inspection of the vertical check valve during its transport process. The inspection data is collected, analyzed, and output by the controller. When a defective product is detected, the electrically controlled winch 214 winds up the rope to raise the height of the bottom correction guide seat 220, and then the external support rod 420 extends and retracts, causing the arc-shaped correction claw arm 410 to flip outward to the outside of the valve flange. Then, the arc-shaped correction claw arm 410 retracts inward under the contraction control, fixing the valve column and then lifting it again to separate the valve from the valve and release it to the outside, thereby achieving the purpose of removing defective products.

[0028] like Figure 4 As shown, two horizontal main frame frames 100 and an electrically controlled conveyor belt 200 for conveying vertical check valves can also be used, which can make great use of the rotation gap for synchronous and opposite detection.
