Description

Technical Field

[0001] This utility model relates to the field of flash meter technology, specifically a vertical and horizontal integrated flash meter. Background Technology

[0002] Currently, in the field of industrial inspection, flash gauges have become key equipment for rapid dimensional inspection. However, existing flash gauge technology has a significant limitation: its structural design is usually fixed to a single vertical or horizontal measurement mode.

[0003] Vertical flash inspection instruments excel at inspecting flat parts, such as mobile phone frames and PCB boards, due to their high table load-bearing capacity and stability. However, for complex three-dimensional workpieces with height or requiring side feature inspection, vertical equipment, with its downward-facing camera view, cannot effectively capture the sidewall contours, resulting in blind spots. Conversely, horizontal flash inspection instruments, with their horizontal camera view, are well-suited for inspecting the radial dimensions and sidewall features of shaft and cylindrical parts, but their load-bearing capacity is relatively weaker, and their inspection efficiency and stability for flat parts are inferior to vertical equipment.

[0004] Therefore, in practice, users often need to purchase both vertical and horizontal equipment to meet comprehensive testing needs when faced with tasks of varying structures. This not only results in huge equipment procurement costs and occupies valuable production space, but also brings cumbersome workpiece clamping, repetitive positioning, and data comparison problems when switching between different equipment, seriously affecting the overall efficiency and consistency of testing and leading to low testing efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides a vertical and horizontal integrated flash detector, which can effectively solve the technical problem that current flash detectors are usually fixed in a single detection mode.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0013] Furthermore, the end of the bottom light source is fixed to the frame by a support plate, and the light source end is also provided with a driver and a heat sink connected to the bottom light source.

[0018] Furthermore, the frame is equipped with a controller that is simultaneously connected to the light source, the first detection end, and the second detection end, and a control panel connected to the controller is provided on one side of the frame.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] like Figure 1-3As shown, this utility model provides a vertical and horizontal integrated flash tester. The core structure includes a frame 1, a measuring platform 2, a light source end 3, a first detection end 4, and a second detection end 5. Each component is reasonably arranged on the frame 1 according to functional requirements to form a complete testing system.

[0033] The frame 1, serving as the supporting foundation for the entire equipment, is made of a material with sufficient strength to ensure the overall stability of the equipment. At the center of the frame 1, a measuring platform 2 is provided for placing the workpiece to be inspected. A light source end 3 for providing the inspection light source is installed at the left end of the measuring platform 2, and a first inspection end 4 for horizontal inspection is correspondingly provided at the right end. Simultaneously, a second inspection end 5 for vertical inspection is provided directly above the measuring platform 2.

[0034] This layout arranges the light source 3, the first detection end 4, and the measuring stage 2 in a straight line in the horizontal direction, while the second detection end 5 corresponds to the measuring stage 2 in the vertical direction. This ensures that the optical paths for both horizontal and vertical detection can accurately cover the workpiece detection area, laying the foundation for subsequent accurate acquisition of workpiece images.

[0035] The measuring stage 2 is a key component that supports the workpiece, and its bottom is connected to the frame 1 via the base 6. The base 6 and the frame 1 are rigidly connected to ensure that the base 6 remains stable during equipment operation and does not shift or shake. The measuring stage 2 and the base 6 are also movably connected, allowing the measuring stage 2 to rotate horizontally relative to the base 6. This allows for adjustment of the workpiece's inspection angle during the inspection process, enabling dimensional inspection of the workpiece from different orientations.

[0036] Furthermore, to ensure the coaxiality and stability of the measuring stage 2 during rotation, a locking pin 7 is coaxially inserted inside the measuring stage 2. The end of the locking pin 7 is fixedly connected to the base 6, allowing the measuring stage 2 to rotate axially around the axis of the locking pin 7. This structural design limits the radial displacement of the measuring stage 2, ensuring that it always rotates around a fixed axis, thus avoiding any impact on detection accuracy due to offset.

[0037] Meanwhile, a panel 8 is installed on the top end face of the measuring stage 2. The panel 8 completely covers the top of the locking pin 7. On the one hand, it can prevent the workpiece from directly contacting the locking pin 7, avoiding positioning deviation or surface scratches caused by contact with the locking pin 7. On the other hand, the panel 8 is made of a material with good light transmittance, which will not obstruct the light projected by the light source end 3, ensuring that the outline of the workpiece can be clearly imaged during the subsequent image acquisition process.

[0038] The core component of the light source end 3 is the bottom light source 31. The bottom light source 31 is set horizontally, and its light projection direction is directly facing the measuring stage 2. It is used to project uniform light onto the workpiece on the measuring stage 2, so that the workpiece forms a clear outline shadow under the light, providing sufficient and stable light source conditions for the first detection end 4 to collect horizontal images of the workpiece.

[0039] To achieve the fixed installation of the bottom light source 31, a support plate 32 is provided at the end of the bottom light source 31. One end of the support plate 32 is connected and fixed to the bottom light source 31, and the other end is connected and fixed to the frame 1. The support plate 32 stably supports the bottom light source 31 on the left end of the measuring table 2, ensuring that the position of the bottom light source 31 does not shift and that the light can be accurately projected onto the workpiece placement area of ​​the measuring table 2.

[0040] In addition, the light source end 3 is also equipped with a driver 33 and a heat sink 34. The driver 33 is electrically connected to the bottom light source 31 and is used to control the opening and closing of the bottom light source 31 and the adjustment of the light brightness. The brightness of the light source can be adjusted according to the detection requirements of different workpieces to obtain the best imaging effect. The heat sink 34 is also connected to the bottom light source 31 and is used to dissipate the heat generated by the bottom light source 31 in a timely manner during operation to avoid high temperature affecting the working stability and service life of the bottom light source 31.

[0041] The first detection end 4 is the core structure for realizing horizontal detection. It is used to acquire images of the workpiece in the horizontal direction. It mainly includes a first camera lens 41, a first moving module 42, and a first aperture 43.

[0042] The first camera lens 41 is horizontally positioned, facing the measuring stage 2, and is used to capture the horizontal contour image of the workpiece on the measuring stage 2. To ensure that the first camera lens 41 can accurately acquire images of workpieces of different sizes, the first detection end 4 is equipped with a first moving module 42. The first moving module 42 is connected to one end of the first camera lens 41 and can drive the first camera lens 41 to move horizontally relative to the measuring stage 2. By adjusting the distance between the first camera lens 41 and the workpiece, it is ensured that the lens can clearly focus on the workpiece and acquire an image that meets the detection accuracy requirements.

[0043] A first aperture 43 is also provided around the first camera lens 41. The light projection direction of the first aperture 43 is towards the measuring stage 2, which is used to assist in adjusting the amount of light entering the first camera lens 41. By adjusting the aperture size of the first aperture 43, the amount of light transmitted can be controlled, avoiding overexposure due to excessive light or blurring due to insufficient light, and further optimizing the clarity of the workpiece image.

[0044] Furthermore, to improve the stability and accuracy of the movement of the first camera lens 41, the first detection end 4 is provided with an internally connected first annular member 44. The first camera lens 41 is located inside the first annular member 44 and can move along the axial direction of the first annular member 44. The first annular member 44 guides the movement of the first camera lens 41, limiting the radial displacement of the lens during movement and ensuring that the lens always moves smoothly in the horizontal direction. At the same time, the first aperture 43 is located on the end face of the first annular member 44 near the measuring stage 2, so that the light from the first aperture 43 can more accurately match the acquisition area of ​​the first camera lens 41, improving the light adjustment effect.

[0045] The first moving module 42 comprises a first sliding guide rail 421, a first sliding frame 422, and a first cylinder 423. The first sliding guide rail 421 is fixed to the frame 1, and its extension direction is consistent with the horizontal movement direction of the first camera lens 41. The first sliding frame 422 slides smoothly along the first sliding guide rail 421, and is also fixedly connected to the end of the first camera lens 41, causing the first camera lens 41 to move synchronously. The first cylinder 423 is connected to the first sliding frame 422 and serves as a driving component, controlling the movement of the first sliding frame 422 along the first sliding guide rail 421, thereby adjusting the horizontal position of the first camera lens 41. This structure, through the cooperation of the guide rail and the sliding frame, ensures the linearity and stability of the lens movement, while the cylinder drive enables precise control of the lens position.

[0046] The second detection end 5 is the core structure for realizing vertical detection. It is used to acquire images of the workpiece in the vertical direction. Its structure corresponds to and is adapted to the first detection end 4. It mainly includes a second camera lens 51, a second moving module 52 and a second aperture 53.

[0047] The second camera lens 51 is vertically positioned, facing the measuring platform 2, and is used to capture the vertical contour image of the workpiece on the measuring platform 2 (such as images corresponding to the workpiece's thickness, height, and other dimensions). To accommodate the inspection needs of workpieces of different heights, the second inspection end 5 is equipped with a second moving module 52, which is connected to one end of the second camera lens 51. The second moving module 52 can drive the second camera lens 51 to move up and down relative to the measuring platform 2. By adjusting the distance between the lens and the top of the workpiece, it is ensured that the lens can clearly focus on the vertical contour of the workpiece and obtain accurate image data.

[0048] A second aperture 53 is provided around the second camera lens 51, with the light projection direction of the second aperture 53 facing the measuring stage 2, used to adjust the amount of light entering the second camera lens 51. By controlling the aperture of the second aperture 53, the vertical lighting conditions can be optimized, avoiding light interference that could lead to image quality degradation, and ensuring that the vertical contour of the workpiece can be clearly imaged.

[0049] Similarly, to improve the stability of the lifting and lowering movement of the second camera lens 51, the second detection end 5 is provided with an internally connected second annular component 54. The second camera lens 51 is located inside the second annular component 54 and can be lifted and lowered along the axial direction of the second annular component 54. The second annular component 54 guides the movement of the second camera lens 51, preventing the lens from shifting during lifting and lowering, and ensuring that the lens always moves in the vertical direction. At the same time, the second aperture 53 is located on the end face of the second annular component 54 near the measuring stage 2, so that the aperture light can accurately cover the vertical detection area of ​​the workpiece, precisely matching the lens acquisition requirements.

[0050] The second moving module 52 comprises a second sliding guide rail 521, a second sliding frame 522, and a second cylinder 523. The second sliding guide rail 521 is fixed to the frame 1, and its extension direction is consistent with the lifting direction of the second camera lens 51. The second sliding frame 522 slides along the second sliding guide rail 521, allowing for smooth lifting. Simultaneously, the second sliding frame 522 is fixedly connected to the end of the second camera lens 51, causing the lens to lift synchronously. The second cylinder 523 is connected to the second sliding frame 522 and serves as a driving component, controlling the lifting of the second sliding frame 522 along the second sliding guide rail 521, thereby adjusting the vertical position of the second camera lens 51 and ensuring precise positioning of the lens according to the workpiece height.

[0051] To achieve automated control and operation of the entire equipment, a controller 9 is installed inside the frame 1. The controller 9 is connected to the light source end 3, the first detection end 4, and the second detection end 5. Specifically, the controller 9 is connected to the driver 33 of the light source end 3, which can control the opening, closing, and brightness adjustment of the bottom light source 31; it is connected to the first cylinder 423 and the first camera lens 41 of the first detection end 4, which can control the movement and image acquisition of the first camera lens 41; and it is connected to the second cylinder 523 and the second camera lens 51 of the second detection end 5, which can control the raising and lowering of the second camera lens 51 and image acquisition. At the same time, the controller 9 also has image processing functions, which can analyze and process the image data acquired by the first camera lens 41 and the second camera lens 51, calculate the dimensional parameters of the workpiece, and determine whether the workpiece meets the inspection standards.

[0052] On one side of the frame 1, a control panel 10 is provided. The control panel 10 is connected to the controller 9 and serves as the interface between the operator and the equipment. The control panel 10 is equipped with operation buttons, a display area, and adjustment components. The operator can send commands to the controller 9 through the operation buttons (such as starting the equipment, stopping the equipment, switching the detection mode, etc.), view the working status of the equipment, detection parameters, and detection results through the display area, and manually adjust parameters such as light source brightness and aperture diameter through the adjustment components, thereby achieving convenient control and operation of the equipment.

[0053] When in use, this vertical and horizontal integrated flash detector can flexibly select horizontal testing mode, vertical testing mode, or combined vertical and horizontal testing mode according to testing needs. The following uses the combined vertical and horizontal testing mode as an example to explain the specific working process of the equipment:

[0054] Equipment preparation phase: The operator starts the equipment via the control panel 10. The controller 9 controls the equipment to perform a self-test, checking whether the light source end 3, the first detection end 4, and the second detection end 5 are in normal working condition. After the self-test is passed, the controller 9 controls the first moving module 42 to drive the first camera lens 41 back to the initial position, and controls the second moving module 52 to drive the second camera lens 51 back to the initial position. At the same time, the driver 33 adjusts the brightness of the bottom light source 31 to the preset initial value, and the first aperture 43 and the second aperture 53 are adjusted to the initial aperture, completing the equipment preparation.

[0055] Workpiece clamping stage: The operator places the workpiece to be inspected on the panel 8 of the measuring stage 2, ensuring that the workpiece is located in the center area of ​​the measuring stage 2 (i.e., corresponding to the acquisition area of ​​the first camera lens 41 and the second camera lens 51). If it is necessary to inspect the dimensions of the workpiece at different angles, the operator can manually rotate the measuring stage 2 to rotate it around the locking pin 7 to the target angle. After adjustment, the measuring stage 2 remains stable and the workpiece position is fixed.

[0056] Horizontal Inspection Stage: The operator selects the horizontal inspection function via the control panel 10. Upon receiving the instruction, the controller 9 activates the first moving module 42: the first cylinder 423 drives the first sliding frame 422 to move along the first sliding guide rail 421, causing the first camera lens 41 to move closer to the workpiece until the first camera lens 41 is positioned to clearly focus on the workpiece, at which point the first cylinder 423 stops working. Subsequently, the controller 9 activates the bottom light source 31 at the light source end 3, projecting light through the panel 8 onto the workpiece, creating a contour shadow. Simultaneously, the controller 9 adjusts the first aperture 43 to a suitable aperture size, regulating the amount of light entering the first camera lens 41. After adjustment, the first camera lens 41 begins acquiring images of the workpiece in the horizontal direction and transmits the image data to the controller 9. The controller 9 processes the image data, calculates the horizontal dimensional parameters of the workpiece (such as radial diameter and horizontal length), and transmits the calculation results to the output device.

[0057] Vertical Inspection Stage: After the horizontal inspection is completed, the operator selects the vertical inspection function via the control panel 10. The controller 9 controls the second moving module 52 to start: the second cylinder 523 drives the second sliding frame 522 to descend along the second sliding guide rail 521, moving the second camera lens 51 towards the top of the workpiece until the second camera lens 51 moves to a position where it can clearly focus on the vertical contour of the workpiece, at which point the second cylinder 523 stops working. The controller 9 controls the second aperture 53 to adjust to a suitable aperture, adjusting the amount of light entering the second camera lens 51. Subsequently, the second camera lens 51 begins to acquire images of the workpiece in the vertical direction and transmits the image data to the controller 9. The controller 9 processes the image data, calculates the vertical dimensional parameters of the workpiece (such as thickness, height, etc.), and transmits the calculation results to the output device. Simultaneously, it combines the results with preset dimensional standards to determine whether the workpiece is qualified.

[0058] Inspection Completion Stage: After the inspection is completed, the operator can view the complete inspection results through the connected output terminal. If data needs to be saved, the inspection results (including dimensional parameters, pass / fail criteria, inspection time, etc.) can be stored in the controller 9 or exported to an external device through the operation commands of the control panel 10. Subsequently, the operator removes the workpiece and sends a reset command through the control panel 10. The controller 9 controls the first camera lens 41 and the second camera lens 51 to return to their initial positions, and the bottom light source 31 is turned off. The equipment completes one inspection cycle.

[0059] Compared with traditional technologies, the flash tester provided by this technical solution is compatible with both vertical and horizontal detection structures, allowing the workpiece to be detected in both the horizontal and vertical directions sequentially without frequent transfer or equipment changes on the measuring table 2. This significantly reduces the cost of workpiece transfer, simplifies the overall operation process, effectively avoids the error risk caused by repeated positioning, and significantly improves the overall detection efficiency.

[0060] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
