Description

Technical Field

[0001] This utility model relates to the field of color matching device technology, and in particular, to a color matching device that allows for quick replacement of measuring instruments. Background Technology

[0002] The color matching device uses the colored light from the multi-channel LED lighting system in the light distribution source to color the substrate, so as to achieve a more realistic visual match in terms of color, texture and transmittance of the actual sample, and restore the appearance of the actual sample or the expected appearance to the greatest extent. Customer companies can directly select the final sample through the color matching device, which greatly shortens the sample selection time and improves production efficiency.

[0003] Color matching devices typically include a darkroom, with the sample to be tested placed on one side wall. An illumination light source is positioned in front of the sample within the darkroom to illuminate it. A measuring instrument is mounted at the bottom of the darkroom, acting on the sample to measure parameters such as illuminance, brightness, or reflectivity. Currently, a measuring housing is usually installed at the bottom of the darkroom, bolted to it. The measuring instrument is mounted on this housing. To obtain different measurement parameters, different types of measuring instruments are typically needed. This requires removing the bolts, detaching the measuring housing from the darkroom, and then removing the measuring instrument. Removing the measuring instrument necessitates disconnecting the USB cable connected to it. This disconnection, along with the need to recalibrate the measuring instrument before installing a new one, results in frequent instrument removal and installation, requiring multiple disconnections and recalibrations. This is extremely inconvenient, time-consuming, and significantly reduces color matching efficiency. Utility Model Content

[0019] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] Please see Figures 1-10 This invention provides a color matching device for quickly changing measuring instruments, including a light box 10 and a dark chamber 20 mounted on the light box 10. The light box 10 has an opening on its front side and an opening 101 on its rear side. The dark chamber 20 has a shell structure with an opening on its front side. The front end of the dark chamber 20 is fixedly mounted on the rear side of the light box 10 corresponding to the opening 101. The rear side of the dark chamber 20 has a mounting port 201, on which a sample placement plate 21 is detachably mounted. The sample placement plate 21 cooperates with the mounting port 201. When the sample placement plate 21 is mounted on the mounting port 201, it can close the mounting port 201 to ensure the airtightness of the dark chamber 20 and prevent light leakage. In use, the inner wall of the sample placement plate 21 is used to fix the sample to be tested. In this embodiment, the sample placement plate 21 and the dark chamber 20 are connected by a hinge 202, and the sample placement plate 21 can open or close the mounting port 201 by flipping. In other embodiments, the sample placement plate 21 can also open or close the mounting port 201 by translation, which is not limited here.

[0021] The color matching device for quick-change measuring instruments of this utility model also includes an illumination light source 30, which is fixedly installed in the dark chamber 20 and positioned directly opposite the mounting port 201 for emitting light onto the sample to be tested. In this embodiment, there are two illumination light sources 30, which are symmetrically arranged in the dark chamber 20.

[0022] Please see Figures 7-10The color matching device for quick-change measuring instruments of this utility model also includes a measuring component 40. The measuring component 40 includes a mounting base 41, a housing 42, and a measuring instrument 43. The mounting base 41 is detachably mounted on the bottom of the dark chamber 20. The housing 42 is fixedly mounted on the mounting base 41. The measuring instrument 43 is fixedly mounted inside the housing 42. The housing 42 and the measuring instrument 43 are located inside the mounting base 41. That is, the housing 42 and the measuring instrument 43 are located inside the dark chamber 20. The detection end of the measuring instrument 43 faces the mounting port 201 for detecting the parameters of the sample to be tested.

[0023] The mounting base 41 includes a base body 411 and a connecting ring 412. The upper opening of the base body 411 forms a receiving groove 410. The connecting ring 412 is fixedly connected to the opening end of the base body 411. The receiving groove 410 is used to accommodate the housing 42 and the measuring instrument 43. The connecting ring 412 is used to connect to the bottom of the darkroom 20.

[0024] The connecting ring 412 has a circular ring structure. An overlapping buckle 413 extends radially outward from the outer wall of the connecting ring 412. The overlapping buckle 413 has an arc-shaped plate structure. Please refer to... Figure 6 A through hole 203 is provided on the bottom wall of the darkroom 20. The through hole 203 is a circular through hole and cooperates with the connecting ring 412. A relief groove 204 is formed by recessing outward along the radial direction of the through hole 203 on the hole wall. The relief groove 204 cooperates with the overlapping buckle 413, and the relief groove 204 and the overlapping buckle 413 have the same shape. When the user needs to install the mounting base 41 on the darkroom 20, the connecting ring 412 is adjusted to align with the through hole 203, and the overlapping buckle 413 is aligned with the clearance groove 204. At this time, the mounting base 41 is moved upward, and the connecting ring 412 is inserted into the through hole 203. Simultaneously, the overlapping buckle 413 passes upward through the clearance groove 204. Then, the user rotates the mounting base 41, causing the overlapping buckle 413 to misalign with the through hole 203. At this point, the overlapping buckle 413 overlaps on the inner bottom wall of the darkroom 20, preventing the mounting base 41 from falling off the darkroom 20. Compared to the traditional method of installing the mounting base 41 on the darkroom 20 using bolts, this invention enables one-handed operation, making the assembly and disassembly process simpler and more efficient.

[0025] Furthermore, a sealing ring 414 extends radially outward on the outer wall of the connecting ring 412 below the overlapping buckle 413. The overlapping buckle 413 and the sealing ring 414 are both in contact with the upper and lower surfaces of the bottom wall of the darkroom 20. Thus, when installed in place, the bottom wall of the darkroom 20 is clamped between the overlapping buckle 413 and the sealing ring 414. The sealing ring 414 can limit the installation and also block the light from the edge of the through hole 203 to prevent light leakage.

[0026] Furthermore, there are two overlapping buckles 413, which are respectively disposed on opposite sides of the connecting ring 412. Correspondingly, there are also two clearance grooves 204, with one overlapping buckle 413 corresponding to one clearance groove 204. By setting two overlapping buckles 413, the connecting ring 412 is subjected to uniform force, effectively preventing deformation of the connecting ring 412.

[0027] In addition, the upper opening of the receiving groove 410 is located inside the connecting ring 412, and baffles 415 are provided in the connecting ring 412 at positions that avoid the receiving groove 410 to prevent light in the darkroom 20 from leaking out from the connecting ring 412.

[0028] In this embodiment, a limiting post 205 is protruding from the outer side of the through hole 203 on the inner bottom wall of the dark chamber 20. The limiting post 205 is set on the rotation path of the overlapping buckle 413. When the overlapping buckle 413 passes through the relief groove 204 and rotates the mounting base 41 relative to the dark chamber 20, the overlapping buckle 413 can abut against the limiting post 205. At this time, the mounting base 41 cannot continue to rotate, and the mounting base 41 is installed in place. After installation, the detection end of the measuring instrument 43 is directly facing the mounting port 201, ensuring the accuracy of the installation position of the measuring instrument 43.

[0029] Furthermore, there are two limiting posts 205, which are located on opposite sides of the through hole 203. During the rotation of the mounting base 41, the two overlapping buckles 413 simultaneously abut against the two limiting posts 205. When the overlapping buckles 413 abut against the limiting posts 205, the mounting base 41 and the measuring instrument 43 on it rotate into position, which is beneficial for the user to quickly adjust the measuring instrument 43 into position.

[0030] Please refer to it again. Figure 8 In this embodiment, a first pad 44 and a second pad 45 are installed in the receiving groove 410. The first pad 44 and the second pad 45 are respectively fitted on opposite sides of the receiving groove 410. At this time, the space enclosed between the first pad 44, the second pad 45 and the groove wall of the receiving groove 410 constitutes a mating chamber 440. The outer shell 42 fits into the mating chamber 440, and the outer shell 42 is placed exactly inside the mating chamber 440. As a preferred embodiment, the opposing surfaces of the first pad 44 and the second pad 45 are both set as inclined surfaces, and at an angle of 45° to the horizontal plane.

[0031] The outer casing 42 is provided with a mounting groove 421 that mates with the measuring instrument 43, and the measuring instrument 43 is installed in the mounting groove 421. Thus, when the first pad 44 and the second pad 45 are installed in the receiving groove 410, the outer casing 42 is installed in the mating chamber 440, and the measuring instrument 43 is installed in the mounting groove 421, the relative position between the measuring instrument 43 and the mounting base 41 is determined, which facilitates the quick adjustment of the measuring instrument 43 into position.

[0032] In this embodiment, a first groove 416 is formed on the side wall of the mounting base 41, and a second groove 422 is formed on the side wall of the outer casing 42, with the second groove 422 corresponding to the first groove 416. In use, one end of the USB transmission cable is connected to the measuring instrument 43, and the other end of the USB transmission cable passes through the second groove 422 and the first groove 416 in sequence before extending to the outside of the mounting base 41. During operation, the measuring instrument 43 transmits the collected signals to a device located outside the mounting base 41 for storage.

[0033] To prevent light leakage, a longitudinal plate 46 is fixedly connected to the side of the second pad 45 away from the first pad 44. A sealing element fixing groove 461 is provided on the longitudinal plate 46, and a sealing element 47 is fixedly installed in the sealing element fixing groove 461. The sealing element 47 seals the first groove 416. The sealing element 47 is made of sealing materials such as silicone or rubber. One end of the USB transmission cable passes through the sealing element 47. The sealing element 47 has good deformation ability. When the USB transmission cable passes through the sealing element 47, the sealing element 47 can effectively seal the perforation part, thereby effectively preventing light leakage.

[0034] During use, when the user needs to measure different parameters, they only need to replace the measuring instrument 43. Specifically, the user rotates the mounting base 41 to align the interlocking buckle 413 with the clearance groove 204. At this point, the mounting base 41 along with the measuring instrument 43 on it can be removed downwards. Then, the mounting base 41 with the measuring instrument 43 for measuring specific parameters can be replaced. During this replacement process, it is not necessary to unplug the USB transmission cable from the measuring instrument 43, avoiding the hassle of recalibrating the measuring instrument 43 every time a test is performed. At the same time, by rotating the mounting base 41, the user can quickly adjust the measuring instrument 43 into position by relying on the cooperation between the interlocking buckle 413 and the limiting post 205, shortening the operation time and greatly improving the color matching efficiency.

[0035] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
