Description

Technical Field

[0001] This utility model relates to the field of panel and flexible sheet testing technology, and in particular to a light box assembly for testing equipment. Background Technology

[0002] In the manufacturing process of liquid crystal display panels, the glass substrate and PET flexible film, as core structural layers, require multiple precision processing steps. After processing, the glass substrate and PET flexible film also need to be inspected to detect any manufacturing defects. However, existing technologies typically employ a phased inspection approach. For example, dedicated optical inspection systems are required at process nodes such as glass substrate cutting, cleaning, and coating, while independent optical inspection devices are needed at subsequent process stages such as PET film lamination and hot pressing.

[0003] In the prior art, a testing platform with a light-transmitting glass plate is used to test glass panels and flexible sheets. The glass panels and flexible sheets are placed on the light-transmitting glass plate for testing. There is a light strip assembly on the back of the light-transmitting glass plate, which provides the necessary lighting for testing.

[0004] However, existing testing platforms require the integration of a feeding component for easy sample handling. Since the existing testing platform needs to accommodate a light strip assembly underneath, this inevitably leads to structural interference with the feeding component, increasing the complexity of both the testing platform and the light strip assembly. Furthermore, the complex structure makes replacing the light strip itself more difficult. Therefore, it is necessary to design a light box assembly for the testing platform of a testing device to reduce interference between the light strip assembly and the feeding component, reduce device complexity, and facilitate the replacement and maintenance of the light strip itself. Utility Model Content

[0005] This utility model provides a light box assembly for testing equipment, which has the advantages of simple structure and more convenient replacement and maintenance of the light strip body.

[0006] One technical solution adopted by this utility model is: a light box assembly for a testing device, wherein the testing device is provided with a testing platform, the light box assembly is placed below the testing platform, and a pin assembly and a light strip assembly are fixedly connected inside the light box assembly; a light-transmitting glass plate is provided on the testing platform, and an array of through holes is provided on the light-transmitting glass plate; the pin assembly is provided with an array of pin bodies that can pass through the through holes, and a pin lifting device drives the pin assembly and the light strip assembly to move up and down.

[0007] The light strip assembly includes a light strip fixing frame and a light strip body disposed on the light strip fixing frame. The light strip fixing frame includes a fixing crossbeam in the middle, which is fixedly connected to the top plate in the pin lifting device. Movable frames are provided at both ends of the fixing crossbeam, and multiple light strip fixing rods are provided on the movable frames.

[0008] The top plate is connected to the fixed crossbeam at its center via a third L-shaped fixing block.

[0009] The two ends of the fixed crossbeam are respectively hinged to the movable frame, and the movable frame is fixedly connected to the top plate through the first L-shaped fixing block.

[0010] The two ends of the light strip fixing rod are fixed to the two ends of the movable frame by the second L-shaped fixing blocks.

[0011] The ejector pin assembly includes an ejector pin body and an ejector pin fixing block; the ejector pin fixing block is fixed to the lower part of the two light strip fixing rods, and the ejector pin body connected to the ejector pin fixing block passes through the middle of the two light strip fixing rods; a suction cup is provided at the top of the ejector pin body, and a negative pressure interface is provided at the tail of the ejector pin body.

[0012] The two ends of the light strip fixing rod are folded upward to form flanges, and slots are formed on both sides of the light strip fixing rod; the two ends of the light strip body are locked in the slots.

[0013] The pin lifting device includes a lifting plate, with lifting slide rails at both ends of the lifting plate, the middle part of the top plate being connected to the lifting device, and both ends of the top plate being movably connected to the lifting slide rails.

[0014] The bottom of the light box assembly is provided with a light box cover plate, and a bottom cover beam is provided at the middle position of the bottom of the light box; one end of the light box cover plate is hinged to the shell at the bottom of the light box; the other end of the light box cover plate is movably connected to the bottom cover beam.

[0015] Two light box covers near one end of the bottom cover beam are equipped with pin assemblies; a ring is provided on the bottom cover beam; the pin assemblies and the ring cooperate to open and close the light box covers.

[0016] The beneficial effects of the testing equipment for panels and flexible sheets of this utility model are: 1. This utility model combines a lightbox assembly with a testing platform. The lightbox assembly is equipped with an array of pin bodies. Driven by a pin lifting device, the pin bodies in the pin assembly pass through the array of through holes in the light-transmitting glass plate, allowing for material receiving above the testing platform. After receiving, the pin assembly descends to the working position along with the LED strip assembly, completing the receiving of the sample and its placement on the testing platform. This utility model combines the pin assembly and the LED strip assembly, reducing the length of the pin body. Furthermore, the pin lifting device used in the pin assembly is located on the inner wall of the lightbox housing, optimizing the overall structure and avoiding the increased structural complexity caused by a separate pin lifting device for the pin assembly. It also does not affect the replacement of the LED strip inside the lightbox. 2. The LED strip in this utility model is mounted on a rotatable movable frame, which allows for easy replacement of the LED strip by rotating the frame. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the drawings. The embodiments of this utility model shown in and described with reference to the drawings are merely exemplary, and this utility model is not limited to these embodiments.

[0023] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0024] Example 1 Example 1 provides a lightbox assembly for a testing device, such as... Figure 1 As shown, the testing equipment includes a base 1, a testing platform 3, and a lamp box assembly 5. A rotating shaft 4 is provided on the outer shell of the lamp box assembly 5. The rotating shafts 4 at both ends are rotatably connected to hinge supports 2, and the hinge supports 2 have drive motors that drive the rotating shafts to rotate. The hinge supports 2 are placed on the base slide rail 11 of the base 1. The lamp box assembly 5 and the testing platform 3 can rotate and move along the base slide rail 11 to receive samples 7 to be tested from different feeding directions.

[0025] like Figure 1 as well as Figure 2 As shown, the light box assembly 5 is placed below the detection platform 3 and is fixedly connected to the detection platform 3. A light-transmitting glass plate 31 is provided on the detection platform 3, and an array of through holes 32 are provided on the light-transmitting glass plate.

[0026] like Figure 3 as well as Figure 5 As shown, the light box assembly 5 contains a fixedly connected pin assembly and a light strip assembly. The pin assembly has an array of pin bodies 6 that can pass through the through hole 32. The pin lifting device 57 drives the pin assembly and the light strip assembly to move up and down together. After the pin body 6 passes through the through hole 32, it receives the sample 7 to be tested. After the pin is retracted, the sample 7 falls onto the light-transmitting glass plate 31 of the testing platform 3.

[0027] The light box assembly of this utility model is provided with a pin assembly and a light strip assembly that are fixedly connected. The pin assembly and the light strip assembly move up and down under the drive of the pin lifting device 57 to realize the functions of receiving materials and lighting. Fixedly connecting the pin assembly and the light strip assembly can reduce the increase in the complexity of the device structure caused by setting up the pin assembly separately (a separate pin lifting device is required, which will occupy more internal space of the light box assembly). At the same time, simplifying the structure of the pin assembly also facilitates the replacement of the light strip body on the light strip assembly.

[0028] like Figures 3-5 The present invention illustrates a lightbox assembly 5, which includes a lightbox housing 53, a pin lifting device 57 disposed inside the lightbox assembly 5, a light strip fixing frame, and a bottom lightbox cover plate 52. The lightbox housing 53 is fixedly connected to a testing platform 3. The pin lifting devices 57 are symmetrically arranged on the inner wall of the lightbox housing 53. Each pin lifting device 57 includes a lifting plate 56 fixed to the inner wall of the lightbox housing 53, lifting rails 561 located at both ends of the lifting plate 56, and lifting sliders embedded in the lifting rails 561 at both ends of a top plate 58. The lifting device 57 drives the lifting of the top plate 58. A fixed crossbeam 511 is fixedly connected to the middle of the top plate 58 via a third L-shaped fixing block 581. Movable frames 510 are located at both ends of the fixed crossbeam 511. The movable frames 510 are hinged to the fixed crossbeam 511, for example, via hinges or latches. The movable frames 510 can rotate around the fixed crossbeam 511. The movable frames 510 are fixedly connected to the top plate 58 via a first L-shaped fixing block 582, which is secured with screws. Several LED strip fixing rods 5101 are provided on the movable frames 510. When it is necessary to replace the LED strip body 51 on the movable frames 510, the screws on the first L-shaped fixing block 582 are removed, allowing the movable frames 510 to rotate. After the movable frames 510 are completely lowered, the light box cover 52 can be opened to replace the LED strip body 51. Therefore, the replacement of the LED strip in the light box assembly of this utility model is relatively easy.

[0029] At both ends of the lifting device 57, there are also drag chains 59, which can be used to organize cables or other pipelines.

[0030] The lifting device 57 of this utility model is an existing module, which can be a linear drive device such as a drive cylinder, a drive oil cylinder, or a motor screw structure, used to drive the top plate 58 to slide up and down along the lifting slide rails 561 on both sides of the top plate 58.

[0031] like Figure 3 as well as Figure 5 As shown, the LED strip fixing rods 5101 are equidistantly arranged on the movable frame 510. Both ends of the LED strip fixing rods 5101 are second L-shaped fixing blocks 5102, which are fixedly connected to the movable frame 510 and the LED strip fixing rods 5101 respectively, facilitating the fixing of the LED strip fixing rods 5101 on the movable frame 510. Simultaneously, the sides of the LED strip fixing rods 5101 are folded upwards to form slots 5103 on both sides. The LED strip body 51 can slide into the LED strip fixing rod 5101 through the slots 5103, thus fixing the LED strip body 51. The LED strip body 51 is fixed to the LED strip fixing rod 5101 using a snap-fit ​​method, making the replacement of the LED strip body 51 more convenient and quick.

[0032] The ejector pin assembly is fixed to the LED strip mounting bracket. More specifically, there is a gap between every two LED strip mounting rods 5101 through which the ejector pin body 6 passes, and the ejector pin body 6 is fixed to the lower part of the two LED strip mounting rods 5101. Specifically, the ejector pin assembly includes an ejector pin fixing block 512, which is fixed to the lower part of the two LED strip mounting rods 5101. The ejector pin body 6 connected to the ejector pin fixing block 512 passes through the middle of the two LED strip mounting rods 5101. This application adopts the above-described method of tightly fitting the ejector pin assembly and the LED strip assembly, which can reduce the length of the ejector pin body 6. At the same time, the ejector pin body 6 and the LED strip assembly share the ejector pin lifting device 57 set on the inner wall of the light box housing 53, which can reduce the structural complexity of the lifting device required for the ejector pin assembly. It also facilitates the flipping of the movable frame 510 and the replacement of the LED strip.

[0033] The top of the ejector body 6 is a suction cup, and the tail of the ejector body 6 is a negative pressure interface 513. Negative pressure is connected through the pressure interface 513 at the bottom of the ejector body 6. When the ejector body 6 receives material, the suction cup can firmly hold the sample 7 to be tested. Even if the sample 7 to be tested rotates a certain angle, the testing platform 3 can also rotate the corresponding angle. The ejector assembly will hold the sample 7 to be tested, which has rotated by the same angle, and slowly place it on the testing platform 3 to meet the needs of multi-angle feeding.

[0034] like Figure 4 as well as Figure 5 As shown, a lightbox cover plate 52 is provided at the bottom of the lightbox, and a bottom cover beam 54 is provided in the middle of the bottom of the lightbox. One end of the lightbox cover plate 52 is hinged to the shell at the bottom of the lightbox (fixed by a hinge 531). A retaining ring 541 is provided on the bottom cover beam 54. A pin assembly 55 is fixed at the connection between the two lightbox cover plates 52. The pin assembly 55 cooperates with the retaining ring 541 to open and close the lightbox cover plate 52. When it is necessary to replace the light strip inside the lightbox, the lightbox cover plate 52 can be rotated by opening the pin assembly 55. The rotation direction of the lightbox cover plate 52 is opposite to the rotation direction of the movable frame 510, so it will not affect the rotation of the movable frame 510 or the replacement of the light strip body 51.
