Generally, a colorimeter contains a mirror module, a filter module, a main control module, a heat dissipation module, and a processing module (CMOS module). However, these components are mounted inside the colorimeter's housing via brackets, which increases the volume occupied by each component within the housing and makes installation and arrangement difficult, hindering the miniaturization design of the colorimeter.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0040] See Figure 1 As shown, this application provides an imaging mechanism 100, which includes a housing 110, a reflector module 120, a filter module 130, a main control module 140, a heat dissipation module 150, and a processing module 160. The imaging mechanism 100 can quantify the color of a light source to detect color deviation in a product under inspection. In this embodiment, the product under inspection is a display module. Of course, in other feasible embodiments, the product under inspection can also be a semiconductor chip, a wearable watch, etc. This application does not limit the specific component type of the product under inspection.

[0041] The housing 110 has a plurality of sidewalls 111, which surround and form a cavity 112. Exemplarily, the housing 110 is a polyhedron, such as a rectangular housing 110 having six sidewalls 111 surrounding and forming a cavity 112, or a hexagonal housing 110 having eight sidewalls 111 surrounding and forming a cavity 112. For other shapes of housing 110, the above examples are used as a reference, and will not be described in detail here.

[0042] The mirror module 120, filter module 130, main control module 140, heat dissipation module 150, and processing module 160 are all located in the cavity 112, and are all disposed on the side wall 111. The mirror module 120 reflects the collected light to the spectrometer for color analysis. The filter module 130 attenuates and filters specific light colors and transmits the attenuated and filtered light to the mirror module 120 and the processing module 160. The main control module 140 controls the various components inside the housing 110 (such as the reflector module 120, filter module 130, and processing module 160). The main control module 140 can be a programmable logic controller (PLC), microcontroller unit (MCU), or embedded processor. The heat dissipation module 150 is used to quickly dissipate heat from the components inside the housing 110 to ensure the operational stability of the imaging mechanism 100. The heat dissipation module 150 can be an air-cooled or water-cooled structure. The processing module 160 is used for the quantification and measurement of light to detect color deviation in the product under inspection.

[0043] The imaging mechanism 100 described above has the mirror module 120, filter module 130, main control module 140, heat dissipation module 150, and processing module 160 all located on the side wall 111 of the housing 110. Without the need for additional fixing components (such as mounting brackets), the mirror module 120, filter module 130, main control module 140, heat dissipation module 150, and processing module 160 can be installed and fixed. The positions of the mirror module 120, filter module 130, main control module 140, heat dissipation module 150, and processing module 160 inside the housing 110 are more compact, which is easy to install and arrange inside the housing 110 and is conducive to the miniaturization design of the imaging mechanism 100.

[0044] In one embodiment, see Figure 1 As shown, the reflector module 120, filter module 130, main control module 140, heat dissipation module 150, and processing module 160 are all detachably connected to the side wall 111. For example, the reflector module 120, filter module 130, main control module 140, heat dissipation module 150, and processing module 160 can be detachably connected to the side wall 111 by screwing, or by snap-fitting. Of course, the connection method between each component and the housing 110 is not limited to the screwing and snap-fitting methods provided above; other detachable connection methods are also possible, and this application does not impose any limitations.

[0045] The imaging mechanism 100 described above can detachably connect the mirror module 120, filter module 130, main control module 140, heat dissipation module 150 and processing module 160 to the side wall 111. When one or more of these components are damaged, it is convenient to disassemble the corresponding component for repair or replacement without scrapping the entire imaging mechanism 100, thus reducing the operating cost of the imaging mechanism 100.

[0046] Further, see Figure 1 and Figure 2 As shown, the housing 110 is provided with an operation window 113 and an operation port 114 that penetrates the housing 110. The operation window 113 is sealed within the operation port 114 to enclose the internal environment of the cavity 112 and ensure the stability of the operating environment of the imaging mechanism 100. The operation window 113 is pivotally connected to the housing 110; or, the operation window 113 is detachably connected to the housing 110. Thus, by rotating or removing the operation window 113, the operation port 114 can be exposed, facilitating the inspection, maintenance, and replacement of the reflector module 120, filter module 130, main control module 140, heat dissipation module 150, and processing module 160 inside the cavity 112.

[0047] In one embodiment, see Figure 1 , Figure 3 and Figure 4 As shown, the reflector module 120 includes a relay module 121, which is connected to the spectrometer via an optical fiber to transmit the light collected by the reflector module 120 to the spectrometer along a preset path. The relay module 121 is connected to a locking fastener 122, which at least partially protrudes to the outside of the housing 110. For example, the operating portion of the locking fastener 122 protrudes to the outside of the housing 110. The locking fastener 122 is used to adjust the relay module 121 and lock it to the housing 110. Thus, since the locking fastener 122 at least partially protrudes to the outside of the housing 110, it can be operated from outside the housing 110 to adjust the angle, position, etc., of the relay module 121, or to perform a locking operation on the relay module 121, making the adjustment and locking operations of the relay module 121 simpler.

[0048] Further, see Figure 1 , Figure 3 and Figure 4As shown, the reflector module 120 is connected to a damping drive component 123, which is driveably connected to the reflector module 120. Since the reflector module 120 integrates a large number of fragile components, by driveably connecting the reflector module 120 to the damping drive component 123, on the one hand, the damping drive component 123 can output power to the reflector module 120, driving the reflector module 120 to complete corresponding actions; on the other hand, the damping drive component 123 can provide braking force to suppress the free movement of the reflector module 120 after power failure, avoiding adverse phenomena such as shaking or even collision damage caused by free rotation of the reflector module 120 in a non-working state.

[0049] In this embodiment, the damping drive 123 can be an electromagnetic damping motor, a hydraulic damping motor, a magnetorheological damping motor, or other components. This application does not limit the specific component type of the damping drive 123.

[0050] In one embodiment, see Figure 1 , Figure 4 and Figure 5 As shown, the filter module 130 includes a fixing bracket 131 and at least one filter 132. The fixing bracket 131 is connected to the side wall 111 by welding, snap-fitting, or other methods to achieve a detachable connection between the filter module 130 and the housing 110. The fixing bracket 131 is provided with multiple connecting slots 133, and the two opposite ends of the filter 132 are respectively snapped into two connecting slots 133, which are dovetail grooves. In this way, by snapping the two opposite ends of the filter 132 into two connecting slots 133, the filter 132 can be fixed to the fixing bracket 131, and the stability of the filter 132 can be ensured. Since the filter 132 is usually suspended inside the cavity 112, the connection slots 133 are designed as dovetail grooves to avoid the risk of the filter 132 falling off.

[0051] Furthermore, the fixing bracket 131 has multiple bosses at the connecting groove 133, and the filter 132 is bonded to the multiple bosses by optical adhesive. Since the filter 132 is set on multiple bosses, it is only necessary to ensure that the multiple bosses and the bonding surface of the filter 132 are at the same horizontal level, which can improve the reliability of the installation level of the filter 132.

[0052] Further, see Figure 1 and Figure 4As shown, the filter module 130 includes a drive source 134, which can drive the filter module 130 to perform corresponding movements. The drive source 134 is provided with a flexible element 135, and the drive source 134 is at least partially in contact with the flexible element 135, such as the flexible element 135 covering the outside of the drive source 134, or the drive source 134 resting on the flexible element 135. This application does not limit the specific installation method of the drive source 134 and the flexible element 135. Furthermore, the flexible element 135 can be made of flexible materials such as rubber, plastic, or porous sponge, and the drive source 134 can be a drive motor, drive cylinder, etc. This application does not limit the specific component types of the flexible element 135 and the drive source 134.

[0053] The aforementioned imaging mechanism 100, through the flexible component 135, can absorb the vibration and noise generated by the drive source 134 during operation, thereby improving the stability of the drive source 134 during movement and thus improving the working stability of the filter module 130.

[0054] In one embodiment, see Figure 1 and Figure 6 As shown, the housing 110 includes a first housing 115 and a second housing 116. The first housing 115 and the second housing 116 are detachably connected, such as by screwing, snap-fitting, or other means, making the housing 110 a separate structure to facilitate the assembly of the imaging mechanism 100. A foolproof marking 117 is provided between the first housing 115 and the second housing 116. The foolproof marking 117 can be a protrusion, recess, or other feature on the housing 110. The foolproof marking 117 improves the ease of assembly of the imaging mechanism 100 and prevents functional defects, rework, or other adverse phenomena caused by fitting errors in the imaging mechanism 100.

[0055] Of course, the foolproof mark 117 is not limited to being set only on the housing 110, but can also be set between other components that have a mating relationship, so as to improve the ease of assembly and the mating accuracy between the components.

[0056] In one embodiment, see Figure 1As shown, the housing 110 is provided with a light inlet 118 for the entry of light. In the direction of light incidence, a filter module 130, a reflector module 120, and a processing module 160 are stacked, with the filter module 130 close to the light inlet 118. For example, the processing module 160 is away from the light inlet 118, and the reflector module 120 is disposed between the filter module 130 and the processing module 160. The filter module 130, reflector module 120, and processing module 160 are spaced apart. Thus, light enters the imaging mechanism 100 through the light inlet 118. The filter module 130 attenuates and filters specific light colors and transmits the attenuated and filtered light to the reflector module 120 and the processing module 160 for color deviation detection of the product under inspection.

[0057] Additionally, see Figure 1 and Figure 7 As shown, this application provides an imaging device 200, which includes a lens module 210 and an imaging mechanism 100 as described above. The lens module 210 is detachably connected to the imaging mechanism 100. The lens module 210 is used to collect the light emitted by the product under inspection for surface defect detection. The imaging mechanism 100 can quantify the color characteristics of the product under inspection. Through the imaging mechanism 100 and the lens module 210, color deviation and surface defects of the product under inspection can be detected simultaneously, improving the inspection efficiency and reducing the inspection cost. Furthermore, since the lens module 210 is detachably connected to the imaging mechanism 100, different specifications of lens modules 210 can be connected to the imaging mechanism 100 to expand the application scenarios of the imaging device 200.

[0058] Both the imaging mechanism 100 and the lens module 210 have signal transmission units. When the lens module 210 is connected to the imaging mechanism 100, the signal transmission units of the imaging mechanism 100 and the lens module 210 are connected to achieve communication between the imaging mechanism 100 and the lens module 210.

[0059] The aforementioned imaging device 200, including the mirror module 120, filter module 130, main control module 140, heat dissipation module 150, and processing module 160, is located inside the cavity 112, with each component disposed on the side wall 111. This allows the components of the imaging mechanism 100 to be directly mounted on the side wall 111 of the housing 110, resulting in a more compact arrangement of components within the housing 110 and facilitating the miniaturization of the imaging device 200. Furthermore, the lens module 210 is detachably connected to the imaging mechanism 100, allowing for the connection of different specifications of lens modules 210 to the imaging mechanism 100, thereby expanding the application scenarios of the imaging device 200.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
