Description

Technical Field

[0001] This invention belongs to the field of workpiece inspection technology, specifically a circular window size inspection mechanism. Background Technology

[0002] A circular window dimensional inspection mechanism is commonly used in precision manufacturing, quality control, and inspection processes, particularly for the dimensional and shape inspection of circular workpieces, seals, or other ring-shaped components. Its primary purpose is to accurately measure the dimensions of the circular window to ensure it conforms to design standards, thereby guaranteeing product functionality and reliability. This equipment is crucial for ensuring the accurate and compliant dimensions of circular workpieces and is widely used in precision manufacturing, quality control, inspection, and automated production lines. Through advanced sensors and automated measurement systems, it improves inspection efficiency and accuracy, making it a key tool for ensuring product quality and production stability.

[0003] Current technologies typically involve manual inspection of circular workpieces. However, manual inspection is inherently subject to subjective factors, such as improper use of measuring tools, non-standard operating procedures, and visual errors. Furthermore, human reaction speed and accuracy are limited, especially when dealing with complex workpieces or high-precision requirements, making it difficult to guarantee complete consistency in each inspection. Moreover, the errors in manual inspection are uncontrollable and can accumulate over multiple inspections, leading to significant deviations in measurement results and ultimately affecting product quality standards. Summary of the Invention

[0004] To address the problem of errors that easily occur during manual inspection as mentioned in the background art, the present invention provides a circular window size detection mechanism.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a circular window size detection mechanism, comprising a base plate, a worktable fixedly connected to the top of the base plate, a rotary gripper motor fixedly connected to the top of the worktable, and a window detection mechanism, the window detection mechanism comprising a rotating shaft fixedly connected to the output end of the rotary gripper motor, a rotary gripper fixedly connected to the top of the rotating shaft, a positioning block fixedly connected to the top of the rotary gripper, a lifting cylinder fixedly connected to one side of the top of the base plate, and a detection component provided on the top of the worktable for detecting the window of the circular workpiece.

[0006] Preferably, the detection component includes an optical fiber sensor fixedly connected to the side of the worktable near the top of the rotary gripper motor, and a backlight is fixedly connected to the top side of the lifting cylinder.

[0007] Preferably, an adjustment mechanism is fixedly connected to the top side of the base plate, and a CCD camera lens is fixedly connected to the movable end of the adjustment mechanism.

[0008] Preferably, the top of the workbench is provided with an auxiliary component, which includes two vertical rods fixedly connected to both sides of the top of the workbench, and an annular shell is fixedly connected to the top of the vertical rods.

[0009] Preferably, a vertical cylinder is fixedly connected to the top of the annular shell, a round tube is fixedly connected to one side of the outer wall of the vertical cylinder, and a square cylinder is fixedly connected to the outer wall of the vertical cylinder away from the round tube.

[0010] Preferably, a fixing ring is fixedly connected to the outer wall of the middle end of the rotating shaft, eight rotating plates are fixedly connected to the outer wall of the fixing ring, and a sealing plate is fixedly connected between two of the rotating plates.

[0011] Preferably, four sealing plates are provided, an annular box is fixedly connected to the bottom of the inner wall of the annular shell, the bottom of the sealing plate contacts the top of the annular box, and a piston plate is slidably connected to the top of the inner wall of the annular box.

[0012] Preferably, a compression spring is fixedly connected to the bottom of the piston plate, the bottom of the compression spring is fixedly connected to the bottom of the inner wall of the annular box, and a conical block is fixedly connected to the top of the piston plate.

[0013] Preferably, one end of the conical block penetrates through the annular box and is slidably connected to the inner wall of the annular box. Four elastic tubes are connected to the bottom of the piston plate around its perimeter. During window inspection, the rotating shaft drives the fixed ring and rotating plate to rotate. As the rotating plate rotates, it contacts the protruding sidewall of the conical block and squeezes it, causing the conical block to drive the piston plate vertically downwards along the inner wall of the annular box. During the descent of the piston plate, it squeezes the airflow inside the rodless area of ​​the annular box, causing the airflow to be expelled through the elastic tubes into the interior of the vertical cylinder. As the airflow flows upwards, it carries dust adhering to the outer wall of the annular workpiece, achieving efficient cleaning, removing dust and impurities from the surface of the annular workpiece, ensuring a clean product surface, and improving the accuracy of subsequent CCD camera lens imaging inspection. The top end of the elastic tube is connected to the inner wall of the top of the annular box.

[0014] Preferably, an arc-shaped ring plate is fixedly connected to the top of the vertical cylinder. The sealing effect of the arc-shaped ring plate and the vertical cylinder reduces the illumination range of the backlight. By reducing the illumination range, the light is more concentrated, reducing light scattering and interference, thereby enhancing the illumination effect on the circular workpiece. This improves the visibility of the circular workpiece surface, making details clearer and facilitating subsequent inspection. An adhesive self-adhesive film is fixedly connected to the inner wall of the arc-shaped ring plate. As the airflow carries dust upwards, the dust adheres to the adhesive self-adhesive film on the inner wall of the arc-shaped ring plate. This effectively captures the dust, preventing it from drifting further with the airflow or contaminating other areas, and preventing the discharged dust from falling back onto the outer wall of the circular workpiece. This ensures that the surface of the circular workpiece remains clean after cleaning, providing a stable and pollution-free environment for subsequent window inspection or processing.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention employs a window detection mechanism. During window detection, a rotating shaft drives a fixed ring and a rotating plate to rotate. As the rotating plate rotates, it contacts the protruding sidewall of a conical block and compresses the block. This causes the conical block to drive a piston plate vertically downwards along the inner wall of the annular box. During the downward movement of the piston plate, the airflow inside the rodless area of ​​the annular box is compressed, causing the airflow to be expelled through an elastic tube into the interior of the vertical cylinder. As the airflow flows upwards, it carries dust adhering to the outer wall of the annular workpiece, achieving efficient cleaning and removing dust and impurities from the surface of the annular workpiece. This ensures a clean product surface and improves the accuracy of subsequent CCD camera lens imaging inspection. As the airflow carrying dust moves upward, it is adhered to the self-adhesive film of the adhesive layer on the inner wall of the arc-shaped ring plate. As the airflow carrying dust flows upward along the inclined surface, the dust will adhere to the inner wall of the self-adhesive film, effectively capturing the dust and preventing it from continuing to drift with the airflow or contaminate other areas. It also prevents the discharged dust from falling back onto the outer wall of the ring workpiece, ensuring that the surface of the ring workpiece remains clean after cleaning, providing a stable and pollution-free environment for subsequent window inspection or processing.

[0017] This invention, through the setting of a window detection mechanism, reduces the illumination range of the backlight by the sealing effect of the arc-shaped ring plate and the vertical cylinder. By reducing the illumination range, the light is more concentrated, reducing light scattering and interference, thereby enhancing the illumination effect on the circular workpiece. It also improves the visibility of the circular workpiece surface, making details clearer and facilitating subsequent inspection. Due to the elastic deformation of the compression spring, when the rotating plate and the sealing plate no longer compress the conical block, the piston plate will reset and rise inside the annular box. At this time, as the rotating plate drives the sealing plate to rotate, it seals the opening at the top of the elastic tube, preventing the elastic tube from generating upward suction. This further reduces the phenomenon of external dust flowing back to the outer wall of the circular workpiece, ensuring that dust is completely removed and that there is no secondary pollution during the cleaning process, thus improving the cleanliness of the circular workpiece surface and the accuracy of inspection.

[0018] This invention utilizes a window detection mechanism to place a circular workpiece on top of a positioning block. A rotating gripper motor drives a rotating shaft and grippers to internally support and clamp the workpiece. Once positioned, a lifting cylinder lowers the backlight. When the backlight reaches a designated height, it illuminates the workpiece. The rotating grippers then begin rotating the workpiece, triggering a fiber optic sensor. The sensor stops when it detects the edge of the window, marking the workpiece's origin. After determining the origin, the workpiece continues to rotate by a certain angle. Since the CCD camera lens is horizontally mounted, when the workpiece reaches the predetermined angle, the window aligns with the CCD lens, and the camera begins detecting the first window. The rotation continues, detecting all windows sequentially. The height of the CCD lens can be adjusted using a control mechanism to inspect workpieces of different sizes, ensuring accuracy. This process achieves comprehensive, continuous, and automated inspection, improving efficiency and completeness. During inspection, the protection provided by the annular shell and vertical cylinder reduces the amount of external dust falling onto the outer wall of the workpiece. At the same time, the circular tube and square tube on both sides of the vertical cylinder allow the light from the fiber optic sensor and the image captured by the CCD camera lens to be precisely aligned with the window of the annular workpiece, thus improving the accuracy of the inspection.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 7 As shown, the present invention provides a circular window size detection mechanism, including a base plate 1, a worktable 2 fixedly connected to the top of the base plate 1, a rotary gripper motor 3 fixedly connected to the top of the worktable 2, and further including;

[0029] The window inspection mechanism 4 includes a rotating shaft 41 fixedly connected to the output end of the rotating gripper motor 3, a rotating gripper fixedly connected to the top of the rotating shaft 41, a positioning block 42 fixedly connected to the top of the rotating gripper, a lifting cylinder 43 fixedly connected to one side of the top of the base plate 1, and an inspection component 44 set on the top of the worktable 2 for inspecting the window of the circular workpiece.

[0030] The detection component 44 includes an optical fiber sensor 441 fixedly connected to the top side of the worktable 2 near the top of the rotary gripper motor 3, and a backlight 442 fixedly connected to the top side of the lifting cylinder 43.

[0031] Using the above scheme: the circular workpiece is placed on top of the positioning block 42, and the rotary gripper motor 3 is driven. The rotary gripper motor 3 drives the rotating shaft 41 and the rotary gripper to rotate, and the circular workpiece is internally supported, clamped and positioned. After positioning is completed, the lifting cylinder 43 is driven to lower the backlight 442. When the backlight 442 is lowered to the specified height, the backlight 442 is controlled to start lighting.

[0032] An adjustment mechanism 443 is fixedly connected to one side of the top of the base plate 1, and a CCD camera lens 444 is fixedly connected to the movable end of the adjustment mechanism 443.

[0033] The above scheme is adopted as follows: the rotating gripper starts to drive the annular workpiece to rotate, and the fiber optic sensor 441 starts to work. When the fiber optic sensor 441 detects the edge of the window of the annular workpiece, it stops and takes it as the origin position of the annular workpiece. After the fiber optic sensor 441 determines the origin, the annular workpiece continues to rotate a certain angle. Since the CCD camera lens 444 is horizontally mounted, when the annular workpiece rotates to the predetermined angle, the window is aligned with the lens of the CCD camera lens 444. The CCD camera lens 444 starts to work and detects the first window. Then the product continues to rotate and detects all windows in sequence. The height of the CCD camera lens 444 can be adjusted by controlling the adjustment mechanism 443, which can detect annular workpieces of different sizes.

[0034] like Figures 1 to 6 As shown, an auxiliary component 45 is provided on the top of the workbench 2. The auxiliary component 45 includes two vertical rods 451 fixedly connected to both sides of the top of the workbench 2. An annular shell 452 is fixedly connected to the top of the vertical rods 451.

[0035] Using the above solution: Due to the elastic deformation of the compression spring, when the rotating plate 457 and the sealing plate 458 no longer compress the conical block 4511, the piston plate 4510 will reset and rise inside the annular box 459. At this time, the rotating plate 457 will block the opening at the top of the elastic tube 4512 during the rotation of the sealing plate 458, preventing the elastic tube 4512 from generating upward suction, and further reducing the phenomenon of external dust flowing back to the outer wall of the annular workpiece.

[0036] A vertical cylinder 453 is fixedly connected to the top of the annular shell 452. A round tube 454 is fixedly connected to one side of the outer wall of the vertical cylinder 453. A square tube 455 is fixedly connected to the outer wall of the vertical cylinder 453 away from the round tube 454.

[0037] A fixing ring 456 is fixedly connected to the outer wall of the middle end of the rotating shaft 41. Eight rotating plates 457 are fixedly connected to the outer wall of the fixing ring 456. A sealing plate 458 is fixedly connected between two rotating plates 457.

[0038] Four sealing plates 458 are provided. An annular box 459 is fixedly connected to the bottom of the inner wall of the annular shell 452. The bottom of the sealing plate 458 contacts the top of the annular box 459. A piston plate 4510 is slidably connected to the top of the inner wall of the annular box 459.

[0039] A compression spring is fixedly connected to the bottom of the piston plate 4510, and the bottom of the compression spring is fixedly connected to the bottom of the inner wall of the annular box 459. A conical block 4511 is fixedly connected to the top of the piston plate 4510.

[0040] One end of the conical block 4511 passes through the annular box 459 and is slidably connected to the inner wall of the annular box 459. Four elastic tubes 4512 are connected to the bottom of the piston plate 4510. The top of the elastic tubes 4512 is connected to the top inner wall of the annular box 459.

[0041] The above scheme is adopted as follows: When the window is inspected, the rotating shaft 41 drives the fixed ring 456 and the rotating plate 457 to rotate. When the rotating plate 457 rotates, it will contact the protruding side wall of the conical block 4511 and squeeze the conical block 4511. This causes the conical block 4511 to drive the piston plate 4510 to descend vertically on the inner wall of the annular box 459. During the descent of the piston plate 4510, it will squeeze the airflow inside the rodless area of ​​the annular box 459, causing the airflow to be sprayed into the interior of the vertical cylinder 453 through the elastic tube 4512. During the upward flow of the airflow, it can carry the dust attached to the outer wall of the annular workpiece to float upward, achieving efficient cleaning and removing dust and impurities from the surface of the annular workpiece.

[0042] An arc-shaped ring plate 4513 is fixedly connected to the top of the vertical cylinder 453. An adhesive self-adhesive film 4514 is fixedly connected to the inner wall of the arc-shaped ring plate 4513. The arc-shaped ring plate 4513 and the adhesive self-adhesive film 4514 can be quickly disassembled and assembled with the vertical cylinder 453 and spliced ​​by snap-fit.

[0043] The above-mentioned solution works as follows: As the airflow carries dust upwards, the dust comes into contact with the self-adhesive film 4514 with an adhesive layer on the inner wall of the arc-shaped ring plate 4513. When the airflow flows upwards along the inclined surface of the arc-shaped ring plate 4513, the dust is adhered to the inner wall of the self-adhesive film 4514 by the combined action of airflow inertia and the adsorption effect of the adhesive film 4514, thus achieving effective dust collection. This structural design not only prevents dust from continuing to diffuse with the airflow but also avoids dust falling back onto the outer wall of the ring workpiece, thereby reducing secondary pollution, ensuring the cleanliness of the ring workpiece surface, and providing a more stable and clean environment for subsequent inspection or processing.

[0044] Working principle and usage process of this invention:

[0045] The circular workpiece is placed on top of the positioning block 42. The rotary gripper motor 3 is driven, which drives the rotating shaft 41 and the rotary gripper to rotate, providing internal support and clamping positioning for the circular workpiece. After positioning, the lifting cylinder 43 is driven to lower the backlight 442. When the backlight 442 reaches the designated height, it is controlled to illuminate. At this time, the rotary gripper begins to rotate the circular workpiece, and the fiber optic sensor 441 starts working. The sensor stops when it detects the window edge of the circular workpiece, which serves as the origin position of the workpiece. After determining the origin, the annular workpiece continues to rotate at a certain angle. Since the CCD camera lens 444 is horizontally mounted, when the annular workpiece rotates to the predetermined angle, the window aligns with the lens of the CCD camera lens 444. The CCD camera lens 444 then begins to work and detects the first window. Subsequently, the product continues to rotate, and all windows are detected sequentially. The height of the CCD camera lens 444 can be adjusted by controlling the adjustment mechanism 443, enabling the detection of annular workpieces of different sizes to ensure detection accuracy. Through the above operations, comprehensive, continuous, and automated detection is achieved, improving detection efficiency and completeness. During detection, the annular shell 452 and the vertical cylinder 453 provide protection, reducing the amount of external dust falling onto the outer wall of the workpiece. Furthermore, the circular tube 454 and square tube 455 on both sides of the vertical cylinder 453 ensure precise alignment of the light from the fiber optic sensor 441 and the image captured by the CCD camera lens 444 with the window of the annular workpiece, improving detection accuracy.

[0046] When performing window inspection, the rotating shaft 41 drives the fixed ring 456 and the rotating plate 457 to rotate. When the rotating plate 457 rotates, it will contact the protruding side wall of the conical block 4511 and squeeze the conical block 4511. This causes the conical block 4511 to drive the piston plate 4510 to descend vertically on the inner wall of the annular box 459. During the descent of the piston plate 4510, it will squeeze the airflow inside the rodless area of ​​the annular box 459, causing the airflow to be sprayed into the interior of the vertical cylinder 453 through the elastic tube 4512. As the airflow flows upward, it can carry the dust attached to the outer wall of the annular workpiece to float upward, achieving efficient cleaning, removing dust and impurities from the surface of the annular workpiece, ensuring the cleanliness of the product surface, and improving the accuracy of subsequent CCD camera lens 444 imaging inspection. As the airflow carrying dust moves upwards, it adheres to the self-adhesive film 4514 on the inner wall of the arc-shaped ring plate 4513. As the airflow carries dust upwards along the inclined surface, the dust adheres to the inner wall of the self-adhesive film 4514, effectively capturing the dust and preventing it from drifting further with the airflow or contaminating other areas. It also prevents the discharged dust from falling back onto the outer wall of the ring workpiece, ensuring the surface of the ring workpiece remains clean after cleaning, providing a stable and pollution-free environment for subsequent window inspection or processing. Simultaneously, the blocking effect of the arc-shaped ring plate 4513 and the vertical cylinder 453 reduces the illumination range of the backlight 442. By reducing the illumination range, the light is more concentrated, reducing light scattering and interference, thereby enhancing the illumination effect on the ring workpiece. This improves the visibility of the ring workpiece surface, making details clearer and facilitating subsequent inspection. Due to the elastic deformation of the compression spring, when the rotating plate 457 and the sealing plate 458 no longer compress the conical block 4511, the piston plate 4510 will reset and rise inside the annular box 459. At this time, the rotating plate 457 will block the opening at the top of the elastic tube 4512 during the rotation of the sealing plate 458, preventing the elastic tube 4512 from generating upward suction, further reducing the phenomenon of external dust flowing back to the outer wall of the annular workpiece, ensuring that the dust is completely removed, and that there is no secondary pollution during the cleaning process, thereby improving the cleanliness of the surface of the annular workpiece and the accuracy of detection.
