Description

Technical Field

[0001] This application relates to the technical field of visual inspection equipment, and in particular to portable visual inspection equipment. Background Technology

[0002] When inspecting the appearance of some light-transmitting materials (such as flexible circuit boards), prolonged visual staring at the light source can easily cause eye fatigue. Therefore, existing technologies use a combination of light source and camera to replace manual inspection.

[0003] For example, the prior art (publication number: CN119619158A) discloses a flexible circuit board defect detection system, which realizes assembly line operation by assembling a large frame, a moving device, a detection device, etc.

[0004] However, this device requires an external computing device and has a large frame size, which cannot meet the needs of small-batch testing or production.

[0005] Therefore, improving the portability of visual inspection of light-transmitting materials has become an urgent technical problem to be solved. Utility Model Content

[0006] The technical problem this application aims to solve is: how to improve the portability of visual inspection of light-transmitting materials.

[0007] To address the aforementioned technical problems, this application provides a portable visual inspection device, comprising: a main unit chassis, which integrates a motherboard, a power supply, and a graphics card; a backlight panel and a touch panel on the top of the main unit chassis, the touch panel being used to adjust the brightness of the backlight panel, and the backlight panel being used to place the object to be inspected; and a display, which is vertically fixed to the edge of the main unit chassis, with an angle-adjustable camera connected to the frame of the display, and the angle-adjustable camera having a hinge for adjusting the tilt angle of the angle-adjustable camera.

[0008] In one embodiment, at least one data interface is provided on the upper and lower bezels of the display, and the angle-adjustable camera is provided with a data plug corresponding to the data interface. The angle-adjustable camera is detachably connected to any data interface through the data plug.

[0009] In one embodiment, the data interface is provided with an anti-detachment structure.

[0010] In one embodiment, the data interface is also provided with an anti-slip pad and a buckle.

[0011] In one embodiment, the main unit chassis has exhaust vents on both sides and the rear side, and an intake vent with a dust filter at the bottom.

[0012] In one embodiment, the backlight panel is an LED surface light source.

[0013] In one embodiment, the pitch adjustment range of the angle-adjustable camera is 60 degrees.

[0014] In one embodiment, a notch is provided at the connection between the display and the host chassis, and the notch corresponds to the backlight panel.

[0015] Compared with the prior art, the portable visual inspection device of this application has the following advantages: The portable visual inspection device of this application uses a main unit and a display as a frame, and adopts an angle-adjustable camera instead of a movable camera to adjust the shooting area. With the help of a backlight, it can adapt to the light transmission detection requirements of objects of different sizes. It also uses a touchpad with a smaller footprint instead of the controller of traditional devices, which is convenient for movement and temporary use, and enhances the portability of the inspection device.

[0022] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0023] In the description of this application, it should be understood that the terms "first," "second," etc., in the specification, claims, and accompanying drawings are intended to distinguish similar objects and are not used to describe a specific structure. It should be understood that such terms are interchangeable where appropriate so that embodiments of this application can be implemented in structures other than those illustrated or described. Furthermore, "comprising," "having," and any variations thereof are intended to cover non-exclusive inclusion. For example, a product or device comprising a series of components or units is not necessarily limited to those explicitly listed, but may also include other components or units not explicitly listed but inherent to these products or devices.

[0024] In fields such as electronics manufacturing and display panels, the appearance quality of light-transmitting materials (taking flexible circuit boards as an example) directly determines the performance and reliability of the final product. Defects such as surface scratches, foreign objects, and circuit misalignment in these materials, if not detected in time, can lead to short circuits, abnormal signal transmission, and other malfunctions. Therefore, efficient and accurate appearance inspection of light-transmitting materials is an indispensable quality control step in the production process.

[0025] In the early days, the industry mostly used manual visual inspection to inspect the appearance of translucent materials, where inspectors judged defects by observing the material surface under a light source. However, prolonged focusing on the light source can easily cause eye strain and decreased concentration for inspectors, thus increasing the risk of missed or false detections. Furthermore, the speed of manual inspection is greatly affected by the condition of the personnel, and different personnel have different judgment standards, making it difficult to meet the requirements of large-scale production for inspection stability.

[0026] To address the shortcomings of manual inspection, existing technologies have begun to adopt an automated inspection mode combining a light source and a camera, replacing manual visual inspection with image acquisition and analysis. Patent application CN119619158A discloses a typical flexible circuit board defect inspection system. Using a large fixed frame as a carrier, it integrates a movable material conveying device, a multi-angle light source module, and a high-definition industrial camera, among other core components. The moving device guides the material sequentially through the inspection area, and the camera, in conjunction with the light source, acquires images of the material surface, ultimately achieving continuous, assembly-line inspection and significantly improving inspection efficiency.

[0027] While the aforementioned automation solutions address some of the issues of manual inspection, there are still scenarios in practical applications that cannot be covered. The system's image analysis and defect judgment functions require an external computer and cannot operate independently, increasing the complexity of equipment deployment and space occupation. Although the large rack design is suitable for batch testing on production lines, the overall size of the equipment is large and inconvenient to move, failing to meet the flexibility requirements of small-batch trial production and on-site sampling inspection.

[0028] Based on this, such as Figure 1As shown in the preferred embodiment of this application, a portable visual inspection device 1 includes: a main unit 11 and a display 12.

[0029] The host chassis 11 integrates a motherboard, power supply, and graphics card. A backlight panel 111 and a touch panel 112 are located on the top of the host chassis 11. The touch panel 112 is used to adjust the brightness of the backlight panel 111. The backlight panel 111 is used to place the object to be detected 2. The monitor 12 is vertically fixed at the edge of the host chassis 11. An angle-adjustable camera 121 is connected to the bezel of the monitor 12. The angle-adjustable camera 121 is equipped with a hinge 1211, which is used to adjust the tilt angle of the angle-adjustable camera 121.

[0030] The device adopts an integrated design of the main unit chassis 11 and monitor 12, integrating the core hardware (motherboard, power supply, graphics card) inside the main unit chassis 11, while the monitor 12 serves as an external support structure, thus compressing the space occupied. This design effectively reduces the size of the device, making it easy to carry and move, and is especially suitable for small-batch testing, on-site inspection, or temporary work scenarios.

[0031] Meanwhile, the angle-adjustable camera 121 achieves pitch angle adjustment through the pivot 1211, which can flexibly adapt to light-transmitting materials of different sizes (such as flexible circuit boards), avoiding the complexity of changing equipment required by traditional fixed cameras, and effectively improving the portability of visual inspection of light-transmitting materials.

[0032] It is understood that this application only makes structural improvements, and the control logic for components such as the motherboard, graphics card, and touchpad is no different from the conventional solution, so it will not be described in detail here.

[0033] Moreover, in the actual production process, there may be different testing requirements. For example, some products need to be fully inspected, while others only need to be inspected for specific details.

[0034] Therefore, in one embodiment of this application, at least one data interface 122 is provided on the upper and lower bezels of the display 12, and the angle-adjustable camera 121 is provided with a data plug 1212 corresponding to the data interface 122. The angle-adjustable camera 121 is detachably connected to any data interface 122 through the data plug 1212.

[0035] By designing a detachable connection method and using data interfaces 122 at different positions, the camera can be moved up and down like a sliding rail. The adjustable camera 121's rotating shaft 1211, combined with the selectable data interface 122, enables a wider range of detection needs to be met.

[0036] For ease of understanding, such as Figure 1As shown, a schematic diagram is provided of an angle-adjustable camera 121 mounted on the upper bezel of a display 12 via a data interface 122, enabling it to acquire a larger view of the object 2 to be detected. And as... Figure 2 As shown, the angle-adjustable camera 121 is mounted on the data interface 122 on the lower bezel of the display 12, which is closer to the object 2 to be detected, thus enabling it to acquire more detailed images and detect more detailed structural parts.

[0037] Meanwhile, the detachable design allows users to replace damaged plugs or modules, reducing equipment maintenance costs and adapting to different testing needs.

[0038] In one embodiment of this application, the data interface 122 may also be provided with an anti-detachment structure. The anti-detachment structure may be a structure such as a buckle or an elastic clip to ensure that the data plug 1212 is fixed to the interface, preventing loosening due to vibration or operation, and avoiding detection failure or equipment damage.

[0039] For example, this application also provides an anti-detachment structure, such as Figure 4 The top view of the angle-adjustable camera 121 shown shows that the anti-dislodgement structure of the data plug 1212 can be a hand-tightening screw, and a threaded hole can be provided at the corresponding position of the data interface 122 to fix the data plug 1212 in the data interface 122.

[0040] Furthermore, in one embodiment, the data interface 122 is also equipped with anti-slip pads and latches to reduce the risk of slippage between the data plug 1212 and the data interface 122, especially in humid or high-temperature environments, thereby improving connection reliability. The latches and anti-slip design make operation more intuitive and reduce the possibility of human error.

[0041] In one embodiment, the main unit 11 has exhaust vents 113 on both sides and the rear side, and an air inlet vent with a dustproof mesh 114 at the bottom.

[0042] The exhaust vents 113 on both sides and the rear of the main unit 11, together with the air intake vents of the bottom dust filter 114, ensure the heat dissipation requirements of the equipment under high load operation, preventing overheating and hardware damage. The dust filter 114 prevents dust from entering the heat dissipation system, reducing the impact of dust on heat dissipation efficiency and extending the continuous operating time of the equipment.

[0043] In this application, an interface panel 115 may also be provided on the back of the main unit chassis 11. Several conventional interfaces may be provided on the interface panel 115 to transmit data to other devices or expand the functions of the testing equipment.

[0044] In one embodiment, the backlight 111 is an LED (light-emitting diode) surface light source. The light distribution of the LED surface light source is more uniform, ensuring consistent brightness in the detection area and reducing misjudgments caused by uneven illumination.

[0045] In one embodiment, the pitch adjustment range of the angle-adjustable camera 121 is 60 degrees.

[0046] It is understood that 60 degrees is a pitch angle relative to a reference plane, which can be a plane that coincides with both the axis of the rotating shaft 1211 and the center of the backlight plate 111. In other embodiments of this application, in order to obtain images of different detection areas, the position of the reference plane can be changed, such as near the upper or lower end of the backlight plate 111.

[0047] In one embodiment of this application, as Figure 5 As shown, a notch 123 is provided at the connection between the display 12 and the host box 11, and the notch 123 corresponds to the backlight panel 111.

[0048] By setting a notch 123 corresponding to the backlight 111, the display 12 no longer blocks the width of the object 2 to be detected on the backlight 111, and the object 2 to be detected can pass under the display 12, thereby enabling the detection of a larger object 2, which is especially suitable for detecting the local structure of large objects.

[0049] This application provides a portable visual inspection device 1, which adopts an integrated design of main unit 11 and display 12, integrating the motherboard, power supply, and graphics card. Flexible inspection is achieved through an angle-adjustable camera 121. The device is equipped with a detachable data interface 122, supporting multi-scenario adaptation, improving inspection efficiency and versatility. Optimized heat dissipation structure ensures high-load operation stability, and the LED surface light source provides uniform illumination, improving image quality. The angle-adjustable camera 121 has a 60-degree tilt adjustment range to adapt to different inspection needs. The notch 123 at the edge of the display 12 allows for flexible movement of the backlight panel 111, expanding the inspection range. The overall solution balances portability, flexibility, and reliability, significantly reducing device size and external dependence, improving inspection accuracy and efficiency. It is suitable for small-batch testing, on-site inspection, and other scenarios, providing an efficient and stable solution for the inspection of translucent materials.

[0050] This application significantly reduces the size of the equipment through modular design and integrated structure, meeting the needs of small-batch testing. The detachable data interface 122 and anti-slip structure enhance connection stability and adaptability to complex environments. The synergistic optimization of the LED light source and the angle-adjustable camera 121 achieves accurate and efficient detection, reducing manual operation and lowering the false detection rate. The heat dissipation design ensures long-term stable operation and improves reliability. The notch 123 expands the detection range and enhances practicality. This equipment has significant advantages in portability, detection accuracy, efficiency, and stability, solving the problems of large size, reliance on external devices, and low detection efficiency of traditional equipment, providing an efficient and flexible solution for the field of visual inspection.

[0051] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
