Description

Technical Field

[0001] This application relates to the field of backlight technology, and in particular to a backlight testing device. Background Technology

[0002] As LCD displays and backlight modules evolve towards larger sizes, thinner profiles, narrower bezels, and more diverse form factors, backlight sources require rapid online or offline testing before shipment to ensure factors such as brightness uniformity, color temperature consistency, light leakage, foreign matter removal, and electrical properties. Industrial sites commonly employ visual inspection or photoelectric sampling methods in conjunction with mechanical movement to complete large-area scanning. However, due to the variety of product specifications and high cycle time requirements, testing equipment must cover a larger inspection area while ensuring measurement accuracy and compatibility with backlight panels of different sizes and types.

[0003] Existing equipment typically achieves strip scanning by reciprocating along a single direction on a support platform, or by moving the detection head within one or two degrees of freedom to complete local stitching. Some systems attempt to expand coverage by lengthening the single-axis stroke, adding temporary fixtures, or adjusting the height and lateral position within a limited range, but the overall system still revolves around a single main motion axis, with displacements in other directions being mostly auxiliary. This limits the stroke and response speed, creating limitations when adapting to complex product ranges and large-area inspection scenarios.

[0004] Existing solutions primarily rely on single or limited degrees of freedom motion, making it difficult to cover the entire area of ​​the support platform without changing fixtures or repeated positioning. Blind spots easily form in the width direction, and height adjustment is insufficient for quickly adapting to backlight panels of different thicknesses and clamping heights, leading to frequent focusing, accumulated splicing errors, and reduced cycle time. In production environments with multiple sizes, various templates, and high yield requirements, these limitations hinder the equipment's scene compatibility and efficiency. Therefore, a more flexible backlight inspection device with multi-directional motion coordination is needed to expand the effective inspection range and cover more application scenarios, thus solving these problems.

[0031] An embodiment of this application provides a backlight detection device, the detection device comprising:

[0032] A base and a support platform disposed on the base, the support platform being movable along the length direction of the base;

[0034] The first movable component is mounted on the fixed frame and moves vertically; the second movable component is mounted on the first movable component and moves along the length of the base; the third movable component is mounted on the second movable component and moves along the width of the base.

[0035] The detection component is mounted on the third moving component and is located above the support platform in the vertical direction. When the support platform moves to below the detection component, the moving component drives the detection component to move, which is used to detect the backlight panel.

[0036] The backlight testing device provided above, by setting a first moving part, a second moving part and a third moving part in the moving component, enables the testing part to move independently along the vertical direction, the length direction of the base and the width direction of the base respectively. When the supporting platform moves to the bottom of the testing part, the testing part can flexibly adjust its position under the three-way linkage, realizing flexible multi-directional motion coordination to expand the effective detection range and cover more application scenarios.

[0037] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] Please see Figures 1-4This application provides a backlight testing device 100, including a base 10 and a support platform 20 thereon, the support platform 20 being movable reciprocally along the length of the base 10. A matching moving mechanism 30 consists of a fixed frame 31 and a moving component 32 thereon. The moving component 32 is provided with a first, second, and third moving member 323 in sequence. The first moving member 321 is mounted on the fixed frame 31 and can be vertically raised and lowered; the second moving member 322 is located on the first moving member 321 and can move along the length of the base 10; the third moving member 323 is located on the second moving member 322 and can move along the width of the base 10. A testing member 40 is mounted on the third moving member 323 and is vertically positioned above the support platform 20. When the support platform 20 moves below the testing member 40, the moving mechanism 30 drives the testing member 40 to make a corresponding displacement to test the backlight panel.

[0039] Specifically, in this embodiment, it should be noted that the backlight testing equipment 100 described in this embodiment includes a base 10, a support platform 20, a moving mechanism 30, and a testing component 40. The base 10 is the basic structural component of the equipment, used to support the entire testing system and provide stable support. The support platform 20 is mounted on the base 10 and can move linearly along the length of the base 10. It is used to carry and transport the backlight panel to be tested, enabling the backlight panel to switch between multiple testing areas during the testing process. Through the movement of the support platform 20, the products to be tested can be transported sequentially to the testing area, reducing manual handling and improving testing efficiency.

[0040] Furthermore, the moving mechanism 30 is installed above the base 10 and consists of a fixed frame 31 and a moving component 32 mounted on the fixed frame 31. The moving component 32 is composed of a first moving member 321, a second moving member 322, and a third moving member 323 arranged in a stacked structure. The first moving member 321 is mounted on the fixed frame 31 and can move vertically to adjust the distance between the detection component 40 and the backlight plate, ensuring that the detection component 40 is always at a suitable working height during the detection process. The second moving member 322 is mounted on the first moving member 321 and can move along the length of the base 10 to achieve precise positioning of the detection component 40 in the length direction. The third moving member 323 is mounted on the second moving member 322 and can move along the width of the base 10 to achieve flexible adjustment of the detection component 40 in the width direction.

[0041] Furthermore, the detection component 40 is mounted on the third moving component 323, located above the support platform 20. When the support platform 20 moves the backlight panel below the detection component 40, the moving component 32 drives the detection component 40 to move in the vertical, length, and width directions, thereby completing the detection of each area of ​​the backlight panel. The detection component 40 can be selected as different types of detection instruments such as cameras, luminance meters, or colorimeters as needed, flexibly adapting to different detection tasks.

[0042] In one specific embodiment, the base 10 includes a frame 11 and a first guide rail 12. The frame 11 has a through groove along the length of the base 10. The first guide rail 12 is disposed on both sides of the through groove. The base 10 plate is disposed on the first guide rail 12. The bearing platform 20 moves along the length of the first guide rail 12.

[0043] Specifically, the base 10 not only serves as the basic frame of the entire machine but also provides guidance and support for the carrying platform 20. A through slot is formed along the length of the base 10, allowing for travel space for the carrying platform 20. First guide rails 12 are installed on both sides of the through slot, arranged parallel to each other and firmly fixed to the frame 11, providing smooth sliding guidance for the carrying platform 20.

[0044] Furthermore, the base plate 10 is mounted on the first guide rail 12, and through sliding engagement with the guide rail, the carrying platform 20 can move smoothly along the length of the guide rail. The carrying platform 20 and the first guide rail 12 can be slidably connected through rollers, sliders, or other low-friction transmission structures to ensure smooth movement and accurate positioning, thereby improving the stability of the backlight panel during transportation and testing.

[0045] In one specific embodiment, the support platform 20 includes a support frame 21, a lifting rod 22, and a lifting plate 23. The support frame 21 is slidably connected to the first guide rail 12 and moves along the length direction of the first guide rail 12. One end of the lifting rod 22 is fixedly connected to the lifting plate 23, and the other end extends into the support frame 21. The lifting rod 22 moves in the vertical direction to push the lifting plate 23 to move, thereby adjusting the distance between the product to be tested and the test piece 40.

[0046] Specifically, the carrying platform 20 consists of a carrying frame 21, a lifting rod 22, and a lifting plate 23. The carrying frame 21 is the main frame of the entire carrying platform 20, and its lower part is slidably connected to the first guide rail 12 on the base 10. Through cooperation with the guide rail, the carrying frame 21 can move smoothly along the length direction of the first guide rail 12, thereby transporting the backlight panel to be tested to the testing station.

[0047] Furthermore, the lifting rod 22 is used to connect and drive the lifting plate 23. One end is fixedly connected to the lifting plate 23, and the other end partially extends into the support frame 21. Its vertical movement stability is maintained by guide holes or guide structures provided in the support frame 21. Driven by an external power source, the lifting rod 22 moves vertically and synchronously moves the lifting plate 23 up and down.

[0048] Furthermore, the backlight panel to be tested is placed on the lifting plate 23. By raising and lowering the lifting plate 23, the distance between the product to be tested and the inspection piece 40 can be flexibly adjusted. This structure allows the carrying platform 20 to not only move and transport products along its length, but also to change the inspection height through the lifting function, providing a more suitable spatial position for subsequent inspections and improving the inspection flexibility of the inspection equipment.

[0049] In one specific embodiment, the detection device further includes a second guide rail 13 disposed on the frame 11 along the length direction of the frame 11, and the fixing frame 31 is slidably connected to the second guide rail 13;

[0050] The moving mechanism 30 also includes a third guide rail 33 disposed on the fixed frame 31. The first moving member 321 is disposed on the side of the third guide rail 33 away from the fixed frame 31 and is fixedly connected to the third guide rail 33.

[0051] Specifically, the testing equipment achieves smooth guidance and movement of the fixed frame 31 by setting a second guide rail 13 along the length of the frame 11. The second guide rail 13 is installed on the frame 11 and firmly connected to it, forming a stable sliding path. The fixed frame 31 is slidably connected to the second guide rail 13 by a slider or roller, enabling it to move linearly along the length of the frame 11, thereby providing reliable guidance and support for the entire moving mechanism 30.

[0052] Furthermore, a third guide rail 33 is provided on the fixed frame 31 to achieve precise guidance of the first moving part 321. The first moving part 321 is set on the third guide rail 33 and located on the side opposite to the fixed frame 31. It is securely installed on the third guide rail 33 by a fixed connection, thereby ensuring that the first moving part 321 is subjected to uniform force and has a stable posture during movement, and will not affect the detection accuracy due to deviation or shaking.

[0053] Furthermore, by combining the second guide rail 13 and the third guide rail 33, a two-level guide structure is formed. The first layer is the overall movement of the fixed frame 31 along the length of the frame 11, and the second layer is the partial movement of the first moving part 321 on the fixed frame 31, which makes the adjustment of the detection part 40 in the length and vertical directions smoother and more precise.

[0054] In one specific embodiment, the first moving member 321 moves vertically along the third guide rail 33 to adjust the vertical movement of the detection member 40.

[0055] Specifically, the first moving part 321 is mounted on the third guide rail 33 and can move up and down along the vertical direction of the third guide rail 33. The third guide rail 33 provides smooth and precise guidance for the first moving part 321, enabling the first moving part 321 to maintain a stable posture and good straightness during movement;

[0056] Furthermore, through this structure, the detection component 40 can be quickly adjusted to a suitable working height according to the thickness, structure or detection requirements of different backlight panels to be tested, so as to ensure that the optical system or sensor is within the optimal detection distance range during the detection process.

[0057] Furthermore, the sliding connection between the first moving part 321 and the third guide rail 33 usually adopts a low-friction structure such as a roller, slider or linear guide rail to ensure the smoothness and accuracy of the movement and to avoid the positional displacement of the detection part 40 due to friction or vibration.

[0058] In one specific embodiment, the moving components 32 are arranged sequentially along the vertical direction.

[0059] Specifically, by arranging the moving components 32 sequentially in a vertical direction, the first moving component 321, the second moving component 322, and the third moving component 323 are arranged in a bottom-up stacked manner to form a stable and smooth motion link. The advantage of this design is that the force is balanced among the moving components, avoiding lateral swaying or tilting during movement, and ensuring that the detection component 40 remains stable during movement.

[0060] Furthermore, the vertically arranged structure ensures that the movement of each moving part does not interfere with each other, the structure is compact, occupies little space, facilitates the overall layout and installation of the equipment, and enables the equipment to achieve multi-directional and multi-degree-of-freedom movement within a limited space.

[0061] Furthermore, the vertical arrangement helps the equipment achieve greater detection flexibility. During the detection process, the second moving part 322 and the third moving part 323 can be precisely positioned in the length and width directions according to the needs of different detection areas after the first moving part 321 is adjusted vertically, allowing the detection part 40 to quickly reach the target position. This structural design not only optimizes the motion control logic but also improves the detection speed and stability.

[0062] In one specific embodiment, a first motor 50 is fixedly connected between the first moving part 321 and the second moving part 322, and a second motor 51 is fixedly connected between the second moving part 322 and the third moving part 323;

[0063] The first motor 50 pushes the second moving member 322 to move along the length direction of the base 10, and the second motor 51 pushes the third moving member 323 to move along the width direction of the base 10.

[0064] Specifically, the first motor 50 and the second motor 51 are driven respectively to achieve coordinated movement of the detection component 40 in both length and width directions. The first motor 50 is fixedly connected between the first moving component 321 and the second moving component 322. When the first motor 50 is activated, it drives the second moving component 322 to move as a whole along the length of the base 10. Simultaneously, the third moving component 323 and the detection component 40 fixedly mounted on it will also move synchronously along the length of the base 10 along with the second moving component 322, thereby achieving a large-scale, rapid movement of the detection component 40 in the length direction.

[0065] Furthermore, the second motor 51 is fixed between the second moving member 322 and the third moving member 323. When the second motor 51 is started, it can directly drive the third moving member 323 to move along the width direction of the base 10. At this time, while the third moving member 323 moves along the overall length direction of the second moving member 322, it can also independently complete the width direction compensation and fine positioning, enabling the detection member 40 to achieve flexible detection path control in a two-dimensional plane.

[0066] In one specific embodiment, the first motor 50 is disposed symmetrically to the second moving member 322 along its length, and the second motor 51 is disposed symmetrically to the third moving member 323 along its length.

[0067] Specifically, the first motor 50 is positioned symmetrically along the length of the second moving member 322, and the second motor 51 is positioned symmetrically along the length of the third moving member 323. This symmetrical arrangement significantly improves the stability and accuracy of the entire moving mechanism 30 during operation.

[0068] Furthermore, the first motor 50 is located at the center symmetrical position of the second moving part 322, which can make the force on both sides balanced when driving the second moving part 322 to move along the length direction of the base 10, so as to avoid the second moving part 322 from tilting, swaying or jamming during the movement due to uneven force, thereby ensuring smooth and stable movement.

[0069] Furthermore, the second motor 51 is installed at a centrally symmetrical position along the length of the third moving member 323, driving the third moving member 323 to move along the width of the base 10. This arrangement ensures that the force on both sides of the third moving member 323 is consistent when it moves in the width direction, preventing torsion or swaying caused by excessive load on one side, and keeping the detection member 40 horizontally stable when performing precise adjustments in the width direction. This is particularly important for high-precision detection of the detection member 40 in edge or local areas, helping to reduce interference from jitter on the detection data and improve the clarity and consistency of the detection results.

[0070] In one specific embodiment, the detection device further includes a light shield 60, which is disposed on the moving component 32 to reduce interference from external light sources.

[0071] Specifically, the detection device has a light shield 60 on the moving component 32. The light shield 60 completely covers the detection component 40 and is fixedly connected to the moving component 32. The shape and size of the light shield 60 are customized according to the layout of the detection component 40 and the detection area of ​​the backlight plate, so that the detection component 40 is always in a relatively closed space during the detection process.

[0072] Furthermore, by forming a closed space around the detection element 40 using the light shield 60, external ambient light is effectively prevented from entering the detection area, reducing stray light interference with the imaging or sensing results of the detection element 40. In this way, the light signal collected by the detection element 40 mainly comes from the backlight panel under test itself, thereby ensuring more accurate and reliable detection data.

[0073] Furthermore, in actual production environments, the light emitted by factory lighting or other equipment may change with time and location, leading to unstable test results. The light shield 60 isolates external light sources, ensuring that the testing conditions remain consistent, thereby guaranteeing the comparability and reproducibility of test data from different times and batches, facilitating quality traceability and statistical analysis.

[0074] In one specific embodiment, the backlight detection device 100 further includes a detection screen 70, which is electrically connected to the detection element 40 and is used to record and visualize the working data of the detection element 40.

[0075] Specifically, the backlight testing device 100 also includes a testing screen 70, which is electrically connected to the testing component 40. This screen is used to receive various data collected by the testing component 40 during the testing process in real time, and to record and visualize this data. The testing screen 70 is typically positioned in a location easily observable by the equipment operator, such as on the side of the base 10 or at the control console, allowing the operator to directly view the real-time testing status during the testing process.

[0076] Furthermore, the detection screen 70 can display the data collected by the detection component 40 in real time, enabling operators to understand the current detection status and results of the backlight panel. During the detection process, if problems such as uneven brightness or light leakage are found, immediate corrective measures can be taken to prevent defective products from continuing to flow into the production process, thus improving the timeliness and accuracy of production line management.

[0077] Furthermore, this embodiment sets up a detection screen 70 in the device, which enables the working data of the detection component 40 to be recorded and visualized in real time. This not only improves the clarity and intuitiveness of the detection data, but also enhances the controllability and traceability of the detection process, providing an efficient, convenient and stable data management and operation platform for backlight panel detection.

[0078] Therefore,

[0079] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
