Description

Technical Field

[0001] The present invention relates to the field of light boxes, and in particular to a visual light box. Background Art

[0002] Currently, in dyeing and finishing laboratories, color matching of fabric samples is generally done visually. The fabric samples to be matched are placed in a color matching light box, which is set with different light sources. Experienced operators then visually identify and determine whether the color meets the requirements. Human observation and judgment are subjective and are likely to be biased by experience and state. Therefore, existing technology has developed a visual light box for color sampling, which can verify visual inspection and visual inspection to reduce the probability of deviation. For this type of visual light box, in order to capture a large area of fabric samples, the camera used for sampling is usually installed on the top of the light box, that is, above the fabric samples, and a monitor is used to display the image captured by the camera. It is understandable that without displaying the image captured by the camera, the operator is not sure whether the camera can accurately capture the area of the fabric sample to be matched. Therefore, a monitor is needed to facilitate manual adjustment of the fabric sample placement position to align with the camera. During this process, a person needs to look at the monitor to adjust the fabric sample position. Therefore, the monitor is set in a more intuitive position. Considering that the front of the box needs to be installed with a transparent glass door, it is obviously difficult to install a monitor on the front of the box that can display the fabric sample. If it is installed on the outside of the box, the operator needs to walk to the side of the box to check whether it is aligned with the camera every time the fabric sample position is adjusted. Specifically, when the operator adjusts the fabric sample inside the box, the upper body will lean forward or even reach into the box to lay and adjust the fabric sample. At this time, the monitor shows the status of the fabric sample in the camera shooting area, which facilitates the operator to make corresponding adjustments. However, if the monitor is set outside the box, the operator needs to repeatedly lean forward, reach in and out, which is very inconvenient. Therefore, the display is usually directly embedded in the inner wall of the box, so that the operator can adjust the position of the fabric sample while looking at the display. For a similar approach, please refer to the fully automatic punching visual inspection machine disclosed in the prior art (authorization announcement number CN218646861U); In actual application, when the lighting component inside the light box is turned on, since the display screen itself will also emit light, the light generated by the display screen will affect the image acquisition quality of the object being measured through reflection, scattering, etc., resulting in imaging deviation or recognition error. Even if the display is turned off (that is, it is not actively emitting light), its screen surface still has a certain degree of reflectivity; secondly, in the process of frequently adjusting the position of the fabric sample, the lighting component is easily bumped into due to the lack of a protective device, and the setting of a special protective device requires a separate control system. Therefore, there is an urgent need for a mechanism that can automatically block the display screen when the lighting component is turned on and protect the lighting component when it is turned off.

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] Based on the existing problem that the objects being measured are prone to detection errors caused by light interference and overheating during image acquisition; please refer to Figure 1-7 The present invention provides a visual light box to solve the above problems, specifically comprising a box body 1 and a shielding portion 2, a toggle member 3 and a baffle 4 arranged inside the box body 1; The shielding portion 2 and the baffle 4 are respectively arranged on opposite sides of the toggle member 3, and the shielding portion 2, the toggle member 3, and the baffle 4 are respectively connected to the box body 1 in rotation. A heat dissipation hole 11 is provided on the top of the box body 1. The toggle member 3 supports one end of the baffle 4 so that the other end of the baffle 4 covers the heat dissipation hole 11. The heat dissipation hole 11 is used to conduct heat generated by the operation of the lighting assembly 9. Part of the shielding portion 2 is arranged on the rotation path of the toggle member 3, and is configured to release the support of the toggle member 3 on the baffle 4 by rotating the toggle member 3 and then open the heat dissipation hole 11, and the toggle member 3 drives the shielding portion 2 to rotate to the front of the display 7 in the box body 1 to block the display 7. This embodiment can automatically open the heat dissipation hole 11 by a simple toggle operation when it needs to be started, and at the same time block the light source of the display 7, effectively controlling the temperature rise while avoiding light interference, and improving the stability and accuracy of image acquisition.

[0026] It should be noted that, considering that the present invention is applied to the detection of cloth, the thickness of the cloth is relatively thin and it is placed flat on the bottom surface of the box, and will not occupy a large space inside the box 1. Therefore, there is enough space to install the shielding part 2. If the object to be detected is other larger objects, it is not suitable for the present invention, and it is necessary to consider that the shielding part 2 will occupy the space of the object to be detected.

[0027] Regarding the heat dissipation holes 11, they are in a closed state by default or when the box body 1 is not in operation. It is understandable that the lighting assembly 9 is usually installed on the top of the light box and is prone to generate a lot of heat during operation. If there is no effective heat dissipation mechanism, the heat accumulation will cause the internal temperature to rise, thereby affecting the stability of image recognition and the service life of the equipment. Therefore, some technical solutions attempt to set heat dissipation holes 11 on the top of the box body 1 to enhance air convection and heat discharge capabilities, but the opening of the heat dissipation holes 11 also brings new problems. Since it is usually directly connected to the external environment, if the heat dissipation holes 11 are kept open, dust, foreign matter and external stray light in the air can easily enter the interior of the light box through the heat dissipation holes 11, which not only affects the cleanliness of the internal environment, but also damages components such as the lighting assembly 9 and the display 7, and may also cause image detection errors. Therefore, it is necessary to open the heat dissipation holes 11 only when the box body 1 is in operation.

[0028] Regarding the opening and closing of the heat dissipation holes 11, in this embodiment, a counterweight 41 is provided at one end of the baffle 4. One end of the baffle 4 is heavier than the other end of the baffle 4. The middle section of the baffle 4 is rotatably connected to the box body 1, thereby ensuring that it can automatically fall when it loses support and drive the other end to rise to cooperate with the opening or closing of the heat dissipation holes 11. This design automatically drives the baffle 4 to move by gravity, simplifies the control mechanism, and achieves automatic opening without electric components, which helps to simplify the structure and reduce the failure rate. Specifically, in order to achieve automatic flipping of the baffle 4 according to the state of the toggle member 3 without relying on an electric device, the present invention provides a counterweight block 41 at one end of the baffle 4, which has a larger mass than the other end, forming a lever-type structure. When the toggle member 3 supports the counterweight end, the baffle 4 remains horizontal to block the heat dissipation hole 11; when the toggle member 3 rotates away from the supporting position, the baffle 4 rotates around the central axis due to the counterweight, with one end drooping and the other end tilting up, thereby automatically opening the heat dissipation hole 11. The automatic flipping of the baffle 4 is achieved by gravity without the need for an additional drive device, making the structure simpler, the response faster, and the operation reliability high. Preferably, a storage slot for accommodating the lighting assembly 9 is provided inside the box body 1, and the heat dissipation hole 11 is provided at the top of the box body 1 and is connected to the storage slot. Under the premise of ensuring good heat dissipation of the lighting system, it effectively prevents dust and pollution, extends the life of the lighting assembly 9, and maintains the clarity of image acquisition.

[0029] The cam 32 is provided with a screw thread 326 which is adapted to move the shutter 4 so as to allow the shutter 4 to move freely in the open position and to allow the shutter 4 to move freely in the open position. In order to realize the linkage control of the toggle member 3 and the shielding part 2, when the toggle lever 31 is rotated, the protrusion will first enter the groove 22 to drive the shielding part 2 to rotate, and then the sector block 32 will enter the arc groove 21. The arc groove 21 is used to guide the sector block 32 and ensure that the sector block 32 has a stable sliding path during the toggle process. It should be noted that although the shielding part 2 and the box body 1 are connected in a rotating manner, in the default state of the present invention, the shielding part 2 will not swing freely or droop due to gravity. To this end, the shielding part 2 is designed to have a certain rotation damping or mechanical limit structure, such as an elastic element, a friction pair or a snap device, so that in the non-toggle state, the shielding part 2 needs to overcome a certain reaction force to complete the rotation. This structure enables the shielding part 2 to maintain a stable horizontal posture when there is no external force interference, avoiding position displacement due to its own weight or slight external vibration; secondly, it is also necessary to reduce the weight of the shielding part 2 to avoid difficulties in designing related rotational damping or mechanical limit structures, and the lighter shielding part 2 will be easily affected by external interference and swing, thereby affecting the shielding effect. Therefore, the cooperation between the fan-shaped block 32 and the arc groove 21 can also prevent the shielding part 2 from swinging due to its light weight.

[0030] Under the above conditions, combined with the cooperation between the fan-shaped block 32 and the arc groove 21, the shielding part 2 will not easily shift and cause additional light interference scenes. This embodiment provides a stable and reliable mechanical transmission method, which allows the shielding part 2 to move synchronously with the action of the toggle member 3, ensuring the coordination of the structure and the smoothness of operation.

[0031] In some embodiments, in order to improve the shading performance of the display 7 area, the present invention provides a lateral protrusion at the second end of the shielding portion 2, so that the shielding portion 2 presents an L-shaped structure. The L-shaped structure has a larger shading angle and coverage area, and can accurately shield the display 7 area when the toggle member 3 drives the shielding portion 2 to rotate.

[0032] In some embodiments, a proximity switch 6 is connected to the box body 1, and the proximity switch 6 is arranged on the side of the lever 31, specifically, on the side of the movement path of the lever 31. The proximity switch 6 is connected to the signal of the lighting component 9 in the box body 1, and the end face of the lever 31 is connected to a sensing part 34 for triggering the proximity switch 6, thereby realizing intelligent linkage between the mechanical structure and the electrically controlled lighting. When the lever 3 is rotated to a specific angle, the sensing part 34 triggers the proximity switch 6 to turn on or off the lighting component 9, thereby realizing automatic control of the light source according to the usage status, improving the intelligence level of the lighting system, automatically controlling the lighting switch in conjunction with the structural action, saving energy and protecting the environment, and avoiding omissions or false triggering of human operations.

[0033] In some embodiments, in order to improve user operation convenience, the toggle member 3 is connected to a transmission shaft extending to the outside of the box body 1, and the end of the transmission shaft is coaxially connected to a handle 33, allowing the user to control the state change of the toggle member 3 by rotating the handle 33 without opening the box body 1, thereby realizing the conversion control of the internal structure, improving the convenience and safety of human-computer interaction, and being suitable for rapid response and frequent operations in a variety of application environments.

[0034] In the present invention, a camera 5 is installed on the top of the box 1 in combination with a lighting component 9. The camera 5 will not be blocked by the blocking portion 2. In the early preparation stage, the camera 5 is used in combination with the display 7 to aim at the area where the fabric sample needs to be matched with the color, and the camera 5 is increased to have a photo acquisition function. After the fabric sample color data is collected, the fabric sample color is identified and the color differences between different fabric samples are compared through algorithm calculation, and the color results are output to the display 7. In addition, the door of the box 1 of the present invention adopts a transparent glass door 8. It can be understood that in addition to using the camera 5 in combination with the lighting component 9 for detection, the present invention is also compatible with manual detection, that is, observing the fabric sample color through the human eye, which makes the applicability of the present invention stronger.

[0035] The lighting assembly 9 or light source specifically includes: artificial fluorescent lamp D65, ultraviolet light source, incandescent light source, CoolWhite Fluorescent (CWF) light source, Triphosphor Lamp P15 (TL84) light source, etc.

[0036] The operation of the equipment is as follows: 1. Place the object to be tested into the box 1, turn on the camera 5 to perform color detection, and output the color data RGB.

[0037] 2. Perform positioning color detection, with a maximum of four points of positioning.

[0038] 3. Detect the colors of two selected points and output the detection results.

[0039] 4. The default detection range is about 300 high × 600 wide (divided into four positions at most).

[0040] 5. Bind the work order QR code, machine number, operator ID, test results and test photos. Once the test begins, it cannot be modified.

[0041] The new device boasts a repeatability accuracy of ≤±1.5%, while retaining all the functionality of the original light box. It features 16DI / 16DO programmable input and output ports (adding to the original light box's functionality), allowing remote access to test results via the internet via software. The lighting assembly (9), or the lamp itself, records usage time and prompts replacement when the designed usage time is reached.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
