The detection method of display surface defects is usually to obtain a clear image of the display surface, and then use a visual defect detection algorithm to automatically identify the defects. When obtaining a clear image of the display surface, it is necessary to use a darkroom and fill the darkroom with light, and then use a camera to shoot.

[0003] The traditional darkroom structure is relatively closed and not easy to open for internal inspection, which results in the heat from the internal light source, detection system and drive mechanism being unable to dissipate, easily leading to heat accumulation inside the darkroom. This will not only reduce the service life of the detection system, but the excessively high temperature will also cause the display's rubber to soften and volatilize. Utility Model Content

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] Example

[0028] Reference Figure 1-Figure 5 As shown, a double-layer ventilated darkroom of the utility model comprises:

[0029] A shell mechanism, comprising: a first shell component 1, a second shell component 2 covered on the first shell component 1, the first shell encloses a darkroom space, the second shell is at least arranged on one side of the first shell component 1, the second shell component 2 comprises at least one layer of outer shell 12, the outer shell 12 and the first shell component 1 on the corresponding side are both provided with air holes 3, and the projections of the air holes 3 on adjacent shells in a direction perpendicular to the shells do not intersect each other;

[0030] A door structure, wherein at least one side of the housing mechanism is provided with a door structure.

[0031] The utility model discloses a double-layer breathable darkroom, wherein the first shell component 1 constitutes the main structure of the darkroom, provides a basic shading function, and ensures a good isolation effect inside the darkroom space. An outer shell 12 is provided, and air holes 3 are provided on the outer shell 12 and the first shell component 1 on the corresponding side. The provision of the air holes 3 ensures air circulation between the double-layer shells. The opening and closing of the door structure can be conveniently and quickly designed to facilitate the detection components to enter or leave the darkroom and for maintenance, thereby achieving a breathable effect and allowing the heat in the darkroom to be dissipated in time. At the same time, the air holes 3 on adjacent shells do not intersect with each other in projections perpendicular to the shell direction, that is, the air holes 3 between the first shell and the outer shell 12, or between adjacent outer shells 12, are staggered, thereby preventing direct transmission of light, and ensuring the shading property of the darkroom while keeping the darkroom breathable.

[0032] In some embodiments, the inner wall of the first shell and the two side walls of the outer shell 12 are coated with a light-absorbing coating, such as carbon black or ultra-black light-absorbing coating. In this embodiment, the first shell component 1, the second shell component 2, and the door component are all made of opaque materials, such as stainless steel or aluminum alloy, and the outer shell 12 has one layer.

[0033] See also Figure 1-Figure 2 As shown, the door structure includes: a first door component 4 arranged on the first side of the shell mechanism, a second door component 5 arranged on the second side of the shell mechanism, and a third door component 6 arranged on the third side of the shell mechanism. The selection of door components can be flexibly determined according to space limitations, safety requirements and usage scenarios. Automatic sensing doors, manual sliding doors and the like can be selected. Sealing strips can be considered to be provided on the edges or around the door components to improve the shading and buffering effects and ensure that the door is well sealed when closed. In addition, the design of the door should take safety into consideration and can be equipped with a safety lock or an electronic lock system to ensure the safety of the equipment inside the darkroom. The lock can be a manual buckle, a plug-in mechanism, a magnetic suction mechanism or a hydraulic automatic door closing mechanism. The first door component 4, the second door component 5 and the third door component 6 can also be equipped with door magnetic sensors to monitor the state of the door in real time. When it is detected that the door is not closed tightly and light leakage occurs, an alarm is issued in time to ensure that the state of the door can be fed back to the door lock system in time.

[0034] The first side, the second side and the third side are respectively arranged on the circumferential sides of the shell in the horizontal direction. The three-side circumferential side arrangement makes the door mechanism more flexible in space utilization. No matter the user approaches from the left, right or front, the door mechanism system can be used conveniently.

[0035] See also Figure 2As shown, the first door assembly 4 is a split door assembly, and the second door assembly 5 is configured as a single door body, which constitutes the side wall of the first housing assembly 1. The split door assembly allows the operator to open two doors at the same time, providing a larger passage width, or open a single door, increasing the door opening flexibility. The second door assembly 5, as a single door body, also constitutes the side wall of the first housing assembly 1. This structural design is compact, not only plays the role of a door body, but also serves as a part of the housing, simplifying the overall structure. When modularly installed, one side of the second door assembly 5 can avoid the surrounding mechanism.

[0036] See also Figure 2 As shown, the third door assembly 6 protrudes from the shell mechanism, and includes a protruding portion 7 arranged on the third side of the first shell assembly 1, and a second door body rotatably connected to the protruding portion 7. The protruding portion 7 extends in a direction away from the wall of the first shell assembly 1, and the opening of the protruding portion 7 is connected to the darkroom space. The third door assembly 6 expands the additional darkroom space without occupying the shell space.

[0037] See also Figure 3-Figure 5 As shown, a partition space 11 is defined between the wall of the first shell component 1 and the outer shell 12 or between adjacent outer shells 12, and the partition space 11 is at least partially filled with a hygroscopic portion 10. The partition space 11 is formed between the wall of the first shell component 1 and the outer shell 12 or between adjacent outer shells 12, and the outer shell 12 and the air holes 3 of the first shell component 1 constitute a non-vertical air permeable channel in the partition space 11. At the same time, the partition space 11 can accommodate the hygroscopic portion 10, and the hygroscopic portion 10 is arranged around the partition space 11.

[0038] The spacing space 11 is provided with a filter layer 9 along the horizontal cross section, and the filter layer 9 filters each air permeable channel to prevent dust from entering the darkroom and affecting the accuracy of the optical components.

[0039] The second shell component 2 is arranged on the top of the first shell component 1. Since the heat generated by the light source and optical components in the dark room causes hot air to move upward, the second shell component 2 and its air permeable channel are arranged on the top, which is beneficial to improving the heat dissipation effect.

[0040] A small compartment 8 is also provided on the fourth side of the shell assembly, and the small compartment 8 is used to accommodate the driving component. The small compartment 8 and the inner wall of the shell mechanism are provided with multiple light source station platforms and detection station platforms. The small compartment 8 is located on the fourth side of the shell assembly, and is specifically used to accommodate the driving component of the detection system. This design isolates the driving component from other parts of the system, avoids the darkroom from occupying too much space, improves the compactness, and improves the overall structural and maintainability of the system.

[0041] The darkroom is modularly configured, the housing mechanism is provided with a plurality of legs, the legs are provided with threaded holes and pin holes, and a detection window is provided at the bottom of the housing mechanism. The modular design enables each darkroom module to be independently processed and installed without affecting the normal operation of other modules. Such a design is conducive to the rapid maintenance and upgrade of the system, reducing maintenance costs. The bottom detection window can be used for the product to be tested to pass through the bottom of the darkroom, and the display to be tested can be tested through the detection mechanism in the darkroom. The modular darkroom can be placed on the assembly line of the display through the legs, increasing the detection efficiency.

[0042] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
