Description

Technical Field

[0001] The present invention relates to the technical field of automation equipment, and in particular to an AI detection device for valve core defects and inner wall flexible polishing of a high-pressure oil pipe joint. Background Art

[0002] In the production and manufacturing of high-pressure oil pipe joints, after the product processing is completed, accurate size detection and efficient sorting of qualified and unqualified products are key links to ensure product quality. Figure 1 The high-pressure oil pipe connector 10 shown has an upper section 101 with an outer diameter greater than that of the lower section 102, and the mass of the upper section 101 is less than that of the lower section 102. Traditional inspection and sorting processes rely primarily on manual labor, requiring inspectors to use measuring tools such as calipers and micrometers to measure key dimensions of the high-pressure oil pipe connector, such as the inner diameter and outer diameter. This process not only requires inspectors to maintain high concentration for extended periods of time, but also, when faced with mass-produced high-pressure oil pipe connectors, manual inspection speed is far from sufficient to keep pace with production. This results in a large backlog of products awaiting inspection, significantly slowing down overall production progress.

[0003] In addition, manual inspection methods have many limitations. Different inspectors have different operating techniques and measurement experience, and their understanding of measurement standards may also be different. This subjective factor makes the inspection results lack consistency and accuracy. Under high-intensity and repetitive working conditions, inspectors are prone to visual fatigue and mental burnout, which leads to frequent false detections and missed detections. Once unqualified products enter the market, it will not only affect the production and assembly of downstream companies, but may also cause serious safety accidents, bringing huge economic losses and reputation risks to the entire industry chain. Therefore, the development of an efficient, accurate and stable high-pressure oil pipe joint size detection and sorting technology has become an industry problem that needs to be solved urgently. Summary of the Invention

[0004] The technical problem to be solved by this application is that traditional manual sorting has low efficiency, poor consistency and high labor intensity. In order to overcome the above defects of the existing technology, this application provides an AI detection and inner wall flexible polishing equipment for high-pressure oil pipe joint valve core defects.

[0005] The present application provides an AI detection and inner wall flexible polishing equipment for the valve core defects of high-pressure oil pipe joints, including: a frame for providing support; a conveying device including a rotating disk and a turntable driver, the rotating disk is rotatably arranged on the frame, the output end of the turntable driver is connected to the rotating disk and drives the rotating disk to rotate, a plurality of positioning seats for positioning high-pressure oil pipe joints are arranged on the rotating disk, the plurality of positioning seats are evenly arranged along the circumferential direction of the rotating disk, a positioning card slot matching the high-pressure oil pipe joint is arranged on the positioning seat, and the opening of the positioning card slot faces outward; a feeding device for providing vertically oriented high-pressure oil pipe joints, a blowing device for removing impurities on the surface of the high-pressure oil pipe joints, a detection device for detecting the high-pressure oil pipe joints, a defective product rejection device, and a qualified product export device are sequentially distributed along the rotation direction of the rotating disk, and the feeding device, the blowing device, the detection device, the defective product rejection device, and the qualified product export device are respectively arranged corresponding to the positioning seats on the rotating disk.

[0006] Compared with the prior art, the AI detection and inner wall flexible polishing equipment for the valve core defects of high-pressure oil pipe joints in the present application has the following advantages: the frame provides stable support for the entire equipment, ensuring that each component can be normally installed and operated; through the cooperation of the rotating disk and the turntable driver, the conveying device can make the high-pressure oil pipe joint rotate with the rotating disk, realizing the automatic transmission of the high-pressure oil pipe joint between each process; a plurality of positioning seats are evenly arranged along the circumferential direction of the rotating disk and are provided with positioning card slots matching the high-pressure oil pipe joint, which can accurately position the high-pressure oil pipe joint, ensure the stability of the high-pressure oil pipe joint during transmission, and facilitate the subsequent devices to operate on the high-pressure oil pipe joint; each device is sequentially distributed along the rotation direction of the rotating disk and is arranged corresponding to the positioning seat, realizing the full-automatic process from the feeding of the high-pressure oil pipe joint, surface impurity removal, detection to defective product rejection and qualified product export, greatly improving the sorting efficiency of the high-pressure oil pipe joint, reducing manual operation, lowering the labor intensity, and at the same time improving the sorting accuracy and consistency.

[0007] In a possible implementation manner, the feeding device includes a vibrating disk and a linear conveying track installed on the frame, the inlet of the linear conveying track is connected to the directional discharging end of the vibrating disk, and the outlet of the linear conveying track faces the opening of the positioning card slot of the positioning seat. Compared with the prior art, the vibrating disk can automatically orient and sort the high-pressure oil pipe joints, enabling the high-pressure oil pipe joints to enter the linear conveying track in a specific posture, eliminating the need for manual placement of the high-pressure oil pipe joints, and improving the feeding efficiency and automation degree; the linear conveying track accurately conveys the high-pressure oil pipe joints directionally output by the vibrating disk to the opening of the positioning card slot of the positioning seat, ensuring that the high-pressure oil pipe joints can smoothly enter the positioning card slot, realizing the automation and precision of the feeding process of the high-pressure oil pipe joints, and further improving the working efficiency of the entire sorting equipment.

[0008] In a possible implementation, the blowing device includes a nozzle installed on the frame. The outlet end of the nozzle faces the positioning slot of the positioning seat, and the inlet end of the nozzle is connected to an external air source. Compared with the prior art, the nozzle provides pressurized air through the external air source, which can blow the surface of the high-pressure oil pipe joint in the positioning slot of the positioning seat to remove impurities such as dust and debris attached to the surface of the high-pressure oil pipe joint. After removing the impurities, the high-pressure oil pipe joint can be more accurately detected by the detection device, avoiding the influence of impurities on the detection result, improving the accuracy of the detection, and thus ensuring the quality of the sorted qualified products.

[0009] In a possible implementation, the detection device includes a camera and a lighting lamp installed on the frame. The lens of the camera is aligned with the positioning slot of the positioning seat and collects the image information of the high-pressure oil pipe joint in the positioning slot. The camera is electrically connected to the defective product rejection device, and the lighting lamp is used to provide illumination. Compared with the prior art, by collecting the image information of the high-pressure oil pipe joint, the camera can detect the size, shape, surface defects, etc. of the high-pressure oil pipe joint. Compared with traditional manual detection, it has higher detection accuracy and efficiency, and can quickly and accurately determine whether the high-pressure oil pipe joint is qualified. The camera is electrically connected to the defective product rejection device, and can transmit the detection result to the defective product rejection device in time to realize the automatic rejection of defective products, improving the automation degree and accuracy of sorting. The lighting lamp provides sufficient and uniform illumination for the camera to collect images, ensuring that the camera can clearly capture the image of the high-pressure oil pipe joint in the positioning slot.

[0010] In a possible implementation, the defective product rejection device includes a push cylinder and a push plate. The push cylinder is installed on the frame, and the push plate is connected to the output end of the push cylinder and is used to push the detected unqualified high-pressure oil pipe joint out of the positioning slot. Compared with the prior art, when the detection device detects a defective product, the push cylinder drives the push plate to act, pushing the unqualified high-pressure oil pipe joint out of the positioning slot, realizing the automatic rejection of defective products without manual intervention, improving the sorting efficiency. This structure is simple and reliable, can accurately and quickly complete the rejection of defective products, and ensures the continuity and stability of the sorting process.

[0011] In a possible implementation, the defective product rejection device further includes a defective product export chute installed on the frame, and the defective product export chute is located below the moving path of the push plate. Compared with the prior art, the defective product export chute is used to receive the defective products pushed out by the push plate, enabling the defective products to be smoothly exported from the device, avoiding the accumulation of defective products in the device and affecting the normal operation of the device. This design makes the collection of defective products more orderly, facilitating the subsequent centralized processing and analysis of defective products.

[0012] In a possible implementation, the qualified product export device includes an export plate installed on the frame. The export plate is provided with an inclined surface for exporting the qualified high-pressure oil pipe joints from the positioning card slots. Compared with the prior art, the inclined surface of the export plate can guide the qualified high-pressure oil pipe joints to be smoothly exported from the positioning card slots, realizing the automatic export of qualified products and improving the efficiency of collecting qualified products. This structural design is reasonable and can ensure the stable export of qualified products, avoiding damage to the high-pressure oil pipe joints during the export process.

[0013] In a possible implementation, the qualified product export device further includes a qualified product guiding trough installed on the frame. The qualified product guiding trough is located below the export plate. Compared with the prior art, the qualified product guiding trough is used to receive the qualified products exported from the export plate, enabling the centralized collection of qualified products, which is convenient for subsequent packaging and transportation. This design makes the collection process of qualified products more automated and standardized, improving the working efficiency and reliability of the entire sorting equipment.

[0014] In a possible implementation, a cleaning device for cleaning the inner hole of the polished high-pressure oil pipe joint is provided between the blowing device and the detection device. The cleaning device includes a fixing frame, a lifter, and a cleaning rod. The fixing frame is installed on the frame, the lifter is installed on the fixing frame, the cleaning rod is connected to the lifting end of the lifter, and the cleaning rod is inserted into the inner hole of the high-pressure oil pipe joint through the drive of the lifter to remove residual impurities. Compared with the prior art, the cleaning device can insert the cleaning rod into the inner hole of the high-pressure oil pipe joint to remove the residual impurities in the inner hole of the high-pressure oil pipe joint, further improving the cleanliness of the high-pressure oil pipe joint. Ensuring that there are no impurities in the inner hole of the high-pressure oil pipe joint can make the detection of the relevant dimensions of the inner hole of the high-pressure oil pipe joint by the detection device more accurate, avoiding inaccurate detection results caused by inner hole impurities, and thus ensuring the quality of the sorted qualified products. At the same time, it can detect whether the inner hole of the high-pressure oil pipe joint is processed, facilitating the detection of inner hole processing.

[0015] In a possible implementation, an arc-shaped enclosing plate fixed to the frame is provided on the outer peripheral side of the rotating disk. The arc-shaped enclosing plate extends from the blowing device to the detection device and is used to prevent the high-pressure oil pipe joints on the positioning seats from slipping out of the positioning card slots. Compared with the prior art, the arc-shaped enclosing plate can prevent the high-pressure oil pipe joints on the positioning seats from slipping out of the positioning card slots during the rotation of the rotating disk, especially when the blowing device blows air on the high-pressure oil pipe joints or the cleaning device cleans the inner holes of the high-pressure oil pipe joints, avoiding the high-pressure oil pipe joints from detaching from the positioning card slots due to external forces, ensuring the stability and safety of the transmission process of the high-pressure oil pipe joints. This design improves the reliability of the equipment operation and reduces equipment failures and sorting errors caused by the detachment of high-pressure oil pipe joints.
