Abstract
Description
Technical Field
[0001] This utility model relates to the field of information acquisition technology, specifically to an information acquisition station for testing samples. Background Technology
[0002] The main function of the information acquisition station used for sample testing is to efficiently and accurately acquire images or data from the sample, providing basic information for subsequent analysis, inspection, or quality control. It is usually equipped with an industrial camera for image acquisition. The industrial camera can provide high-resolution, stable, and fast image capture, ensuring accurate and clear observation and analysis of the detailed features of the sample, which is crucial for achieving automatic detection and defect identification.
[0003] Chinese invention and utility model patent CN206583485U discloses a sample image information acquisition bracket, including a sample stage, an acquisition support column, a supplementary light, an information acquisition fixing platform, and a sample to be tested. The sample stage has an acquisition support column at one end, and an information acquisition fixing platform at the other end. A supplementary light is located at the connection between the acquisition support column and the information acquisition fixing platform. The sample stage consists of a placement plate and a scale strip, with the scale strip fixed to the top edge of the placement plate. An image acquisition window is located in the center of the information acquisition fixing platform, and an anti-reflective coating is applied to the bottom surface of the platform. The sample to be tested is placed on the placement plate. This invention solves the problem of unstable image information acquisition clarity. The supplementary light provides illumination to the sample, and the acrylic plate and anti-reflective coating effectively reduce the environmental impact of reflected light.
[0004] However, existing technologies cannot easily acquire images from multiple points and angles at different positions of the workpiece. This limitation will result in the inability to fully capture the overall features and detailed information of the workpiece, affecting the accuracy and completeness of the inspection. To address this issue, the following improvements are proposed. Utility Model Content
[0005] The present invention aims to provide an information acquisition station for testing samples to solve the problem of being unable to fully capture the overall features and detailed information of a workpiece.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an information acquisition station for testing samples, including a worktable, a turntable rotatably mounted on the worktable, a first driving component for driving the turntable to rotate on the worktable, a plurality of fixtures for mounting workpieces on the turntable, a rotating component for driving the workpiece to rotate on the fixtures, an acquisition component mounted on the worktable above the turntable, and the turntable for driving the workpiece to rotate below the acquisition component.
[0007] The beneficial effects of this solution are as follows: By driving the workpiece to automatically rotate under the acquisition component via a turntable, and cooperating with the acquisition component to acquire images, it is possible to achieve block speed detection of multiple workpieces, reducing the time and error of manual operation. The turntable driving the workpiece to rotate under the acquisition component makes the detection process more orderly, reduces the time for repeated handling and positioning of workpieces, and improves the overall work efficiency. During the detection process, the rotating component drives the workpiece to rotate, so the acquisition component can acquire multi-faceted image information of the workpiece with the cooperation of the rotating component, thereby performing multi-point and multi-angle image acquisition of different positions of the workpiece, which has the effect of comprehensively capturing the overall features and detailed information of the workpiece.
[0008] Preferably, as an improvement, the tooling is provided with a mounting block for fixing the workpiece. The mounting block includes a fixed block fixed to the tooling and a movable block slidably disposed on the tooling. The tooling is provided with an adjustment component for driving the movable block to slide. Workpieces of different lengths are fixed between the fixed block and the movable block by adjusting the component.
[0009] The beneficial effects are as follows: by adjusting the sliding motion of the component driving the moving block, the distance between the fixed block and the moving block can be precisely adjusted, thereby adapting to workpieces of different lengths, ensuring that the workpiece remains stable during processing, and avoiding processing errors caused by insecure fixing.
[0010] Preferably, as an improvement, the adjusting component includes a first slide and a second slide in the tooling, an electric push rod disposed in the first slide, and a guide rod disposed in the second slide. The electric push rod is used to drive the moving block to slide in the first slide, and the guide rod passes through the moving block and is used to guide the moving block.
[0011] The beneficial effects are as follows: the electric linear actuator can achieve precise adjustment of workpieces or components by accurately controlling the sliding position of the moving block, which is suitable for scenarios that require high-precision positioning. The guide rod ensures that the moving block remains stable during the sliding process, avoiding deviation caused by friction or external force, thereby improving the stability and reliability of the overall structure.
[0012] Preferably, as an improvement, the rotating assembly includes rotating disks respectively rotatably disposed on the fixed block and the movable block, the two rotating disks being coaxially rotatably disposed, and the two rotating disks having slots on opposite sides for engaging the workpiece, the adjusting assembly for abutting the workpiece against the two rotating disks, and at least one of the fixed block and the movable block being equipped with a second driving member for driving the rotating disks to rotate.
[0013] The beneficial effects are as follows: by setting slots on the rotating disks on both sides, the workpiece can be effectively fixed between the two rotating disks, ensuring that the workpiece will not be displaced or loosened during rotation, thereby improving the accuracy and safety of processing or inspection.
[0014] Preferably, as an improvement, the moving block is made of magnetic material, and an electromagnet is provided in the tooling along the moving direction of the moving block. The electromagnet is used to buffer the movement of the moving block.
[0015] The beneficial effects are as follows: the electromagnet is set in the direction of the moving block, and the electromagnet is arranged in strips with the magnetic field direction opposite to that of the section close to the moving block. As the moving block moves toward the fixed block, the magnetic force of the electromagnet on the moving block gradually increases. When the electric push rod drives the moving block to press the workpiece between the fixed block and the moving block, the reaction force of the electromagnet on the moving block can buffer the friction between the moving block and the workpiece, thereby protecting the workpiece.
[0016] Preferably, as an improvement, the rotating disk is made of magnetic material, and at least one of the fixed block and the moving block is provided with an electromagnetic block, which is used to buffer the rotation of the rotating disk.
[0017] The beneficial effects are as follows: the electromagnetic block exerts a reverse electromagnetic force on the rotating disk. When the rotating disk stops the workpiece from rotating, the workpiece tends to continue rotating. At this time, the tendency of the workpiece to continue rotating is completely offset by the friction between the workpiece and the rotating disk, which causes serious wear on the workpiece. However, the reaction force of the electromagnetic block on the rotating disk can effectively offset the tendency of the workpiece to continue rotating, thereby reducing the friction between the workpiece and the rotating disk and protecting the workpiece from wear.
[0018] Preferably, as an improvement, the tooling is equipped with a battery assembly and a control module. The battery assembly is used to power the control module, and the electric push rod, electromagnet, electromagnet block, and drive motor are all electrically connected to the battery assembly and the control module.
[0019] Preferably, as an improvement, the worktable is provided with an L-shaped bracket, and the acquisition component includes a controller and an industrial camera mounted on the L-shaped bracket. An image sensor is disposed between the controller and the industrial camera, and the industrial camera and the first driving component are both electrically connected to the controller.
[0020] Preferably, as an improvement, the first driving component is configured as a power motor, and the second driving component is configured as a drive motor. Attached Figure Description

[0023] Example like Figure 1 The illustrated information acquisition station for sample testing includes a workbench 1, an L-shaped bracket 2 fixedly mounted on the top of the workbench 1, and an acquisition component for acquiring image information mounted on the L-shaped bracket 2. The acquisition component includes a controller 3 and an industrial camera 4. The industrial camera 4 is fixedly mounted on the L-shaped bracket 2, and the controller 3 is fixedly mounted on the side of the L-shaped bracket 2. An image sensor is fixedly mounted on the L-shaped bracket 2 and connected between the industrial camera 4 and the controller 3. The controller 3 and the industrial camera 4 are electrically connected through the image sensor. The L-shaped bracket 2 provides installation space for the industrial camera 4. The industrial camera 4 is used to acquire image information of the workpiece, and the acquired image information is transmitted to the controller 3 for processing.
[0024] The workbench 1 has an annular groove 5 inside, and a turntable 6 inside the annular groove 5. The turntable 6 has a limit groove 7 on its side, and a corresponding locking block inside the annular groove 5. When the turntable 6 rotates, it can be guided by the limit groove 7 to make the turntable 6 rotate smoothly. The workbench 1 has a first driving component for driving the turntable 6 to rotate. The first driving component is a power motor 8. The power motor 8 is also electrically connected to the controller 3. A positioning frame 9 is fixedly welded inside the workbench 1. The power motor 8 is fixedly installed inside the positioning frame 9, and the output end of the power motor 8 is coaxially connected to the turntable 6. The positioning frame 9 provides installation space for the power motor 8. When the power motor 8 works, it will drive the turntable 6 to rotate.
[0025] like Figures 2-3As shown, a battery assembly 11 is fixedly installed inside the turntable 6, and a control module 12 is installed inside the turntable 6. Several tooling fixtures 10 are symmetrically arranged on the circumference of the turntable 6. Mounting blocks 13 for fixing workpieces are provided on the tooling fixtures 10. The mounting blocks 13 include a fixed block 131 fixed to the tooling fixture 10 and a movable block 132 slidably arranged on the tooling fixture 10. An adjustment component for driving the movable block 132 to slide is provided on the tooling fixture 10. The adjustment component includes a first slide groove 18 and a second slide groove 20 opened in the tooling fixture 10, an electric push rod 19 fixedly installed in the first slide groove 18, and a guide rod 21 fixedly arranged in the second slide groove 20. The first slide groove 18 and the second slide groove 20 are arranged parallel to each other, and the telescopic end of the electric push rod 19 is fixedly connected to the movable block 132 through a plate. The guide rod 21 passes through the movable block 132.
[0026] like Figure 3 As shown, the tooling 10 is equipped with an electromagnet 22 located in the sliding direction of the moving block 132. The electromagnet 22 is elongated. The electromagnet 22 and the electric push rod 19 are electrically connected to the battery assembly 11 and the control module 12. When the electric push rod 19 is working, it will drive the connected moving block 132 to move, adjusting the position of the moving block 132 to facilitate the positioning and clamping of workpieces of different sizes. When the moving block 132 moves, it can be guided by the guide rod 21 to make the moving block 132 move smoothly. After the moving block 132 moves to the predetermined position, the electromagnet 22 is controlled to work to generate magnetic force, which can buffer the moving block 132 and reduce the friction between the moving block 132 and the workpiece.
[0027] like Figure 3 As shown, the mounting block 13 is equipped with a rotating assembly for rotating the sample. The rotating assembly includes a rotating disk 15 rotatably connected to the fixed block 131 and the moving block 132, and a second driving component set on the fixed block 131. The second driving component is a drive motor 14. The rotating disk 15 has slots 17 for fixing the workpiece on both sides facing each other. The output end of the drive motor 14 is coaxially connected to the rotating disk 15. An electromagnetic block 16 is set inside the moving block 132. The electromagnetic block 16 and the drive motor 14 are electrically connected to the battery assembly 11 and the control module 12. When the drive motor 14 works, it drives the rotating disk 15 to rotate. When the rotating disk 15 rotates, it drives the clamped workpiece to rotate. The slots 17 are used to limit the strip workpiece. The electromagnetic block 16 generates magnetic force to buffer the inertia when the rotating disk 15 stops rotating, thereby reducing the friction between the workpiece and the rotating disk 15.
[0028] When using the information acquisition station to acquire images of a sample's appearance, the workpiece to be imaged is placed on fixture 10. The movement of the adjustment component moves the connected moving block 132, and the movement of the power component rotates the turntable 6. The rotation of the turntable 6 causes the workpiece to rotate, moving it below the acquisition component. The acquisition component can then acquire images of the workpiece surface. Simultaneously, the rotation component moves, causing the workpiece to rotate, allowing for information acquisition from different positions on the workpiece. This significantly improves flexibility and adaptability, enabling data acquisition at multiple key locations without frequent adjustments or repetitive tasks, thus greatly improving work efficiency and accuracy. After acquiring the workpiece's image information, the power component moves, rotating the workpiece and moving any workpieces whose images were not acquired below the acquisition component, further enhancing flexibility and facilitating rapid replacement of different workpieces for image acquisition.
