[0002] During the manufacturing process of mobile phones, titanium alloy frames are often used to enhance the phone's texture. However, residual chemicals, dirt, or unremoved oxide areas from the processing can cause appearance defects such as whitening or discoloration on the frame surface, affecting the yield rate and cost of the phone.

[0045] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0046] The following is for reference. Figures 1-8 The detection device provided in the embodiments of this application is described. The detection device includes a mounting frame 100, a light-emitting structure 200, and an imaging structure 300.

[0047] Mounting bracket 100 is disposed on mounting bracket 100 and is used to emit detection light to the workpiece 900 to be inspected. The light-emitting structure 200 has multiple independently operating light-emitting area groups, and the detection light corresponding to each light-emitting area group has a different orientation. Imaging structure 300 is disposed on mounting bracket 100 and located on the same side as the light-emitting structure 200. Imaging structure 300 is used to obtain a detection image of the workpiece 900 to be inspected. It should be noted that "multiple" includes two or more.

[0048] It should be noted that the component to be tested, 900, includes, but is not limited to, the mid-frame of a mobile phone.

[0049] Understandably, the mounting bracket 100 serves to support and fix the light-emitting structure 200 and the imaging structure 300, ensuring the overall stability and integrity of the detection device and increasing detection accuracy. The light-emitting structure 200, mounted on the mounting bracket 100, has multiple independently operating light-emitting zones, allowing for flexible selection and combination of the working states of each zone according to different detection needs and the characteristics of the workpiece 900. Furthermore, since each light-emitting zone corresponds to a different detection light orientation, the workpiece 900 can be illuminated from multiple different angles, saving time and effort while increasing the comprehensiveness and accuracy of the detection, better capturing the features and details of the workpiece 900 in different directions. The imaging structure 300 obtains detection images of the workpiece 900 in different directions, enabling subsequent analysis and processing of these images to determine whether the workpiece 900 is qualified, thus improving detection efficiency, detection effect, and detection flexibility.

[0050] The detection device provided according to the embodiments of this application not only saves time and effort, but also achieves high efficiency, comprehensiveness, flexibility and accuracy in detection, and can effectively improve detection efficiency and quality.

[0051] In some embodiments, such as Figure 2 and Figure 3 As shown, the light-emitting area group includes two symmetrically arranged light-emitting areas 201, and the two light-emitting areas 201 of at least one light-emitting area group emit light synchronously.

[0052] Understandably, the two light-emitting areas 201 are located on both sides of the workpiece 900 and are symmetrically arranged, thereby providing more uniform illumination of the workpiece 900 and enhancing the contrast of its surface features, reducing quality differences in the inspection image caused by uneven illumination. Furthermore, the simultaneous emission of the two light-emitting areas 201 of at least one light-emitting area assembly not only provides stronger and more stable illumination intensity but also reduces the number of illumination cycles during the inspection of the same workpiece 900, improving inspection efficiency.

[0053] In this embodiment, as Figure 5 and Figure 6 As shown, the three light-emitting zones are arranged sequentially from top to bottom. Specifically, a and b represent the two light-emitting zones 201 in the upper light-emitting zone group, c and d represent the two light-emitting zones 201 in the middle light-emitting zone group, and e and f represent the two light-emitting zones 201 in the lower light-emitting zone group. The two light-emitting zones 201 in each light-emitting zone group emit light synchronously. Of course, in other embodiments, the two light-emitting zones 201 in the middle light-emitting zone group can also emit light independently, i.e., c and d can operate independently of each other, thereby increasing the flexibility of the light-emitting device.

[0054] In some embodiments, such as Figures 1 to 5As shown, the light-emitting structure 200 includes two light-emitting elements 211, which are disposed on the mounting bracket 100. The test piece 900 is located between the two light-emitting elements 211. The light-emitting surface of the light-emitting element 211 has multiple light-emitting areas 201 arranged sequentially along the first direction and operating independently.

[0055] It should be noted that the first direction is parallel to the vertical direction, and the first, second, and third directions intersect each other.

[0056] Understandably, the light-emitting areas 201 at the same height in the two light-emitting elements 211 form a light-emitting area group, realizing a three-dimensional and distributed illumination pattern, thereby illuminating the test piece 900 from multiple angles and heights, significantly enhancing the comprehensiveness and accuracy of the detection.

[0057] In some embodiments, such as Figure 4 As shown, the two light-emitting elements 211 are symmetrically arranged so that the light-emitting area group includes two symmetrically arranged light-emitting areas 201.

[0058] It should be noted that, in combination Figure 4 As shown, L1 is the axis of symmetry and is parallel to the third direction. The two light-emitting elements 211 are symmetrical about the axis of symmetry.

[0059] In some embodiments, the test piece 900 may also be symmetrically arranged around the axis of symmetry during the testing process to improve the testing accuracy. This embodiment does not impose specific limitations on this.

[0060] In some embodiments, such as Figure 2 As shown, the luminescent surface is an arc surface, and the center of curvature of the arc surface is located on the side away from the imaging structure 300. It should be noted that the size and shape of the arc surface can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0061] Understandably, utilizing a curved surface allows for a more concentrated and uniform distribution of the detection light, better adapting to the shape of the workpiece 900 and providing uniform illumination. Simultaneously, the center of curvature of the curved surface is located on the side furthest from the imaging structure 300. That is, the curved surface bulges towards the imaging structure 300, enabling the detection light to better cover the surface of the workpiece 900 during propagation, reducing blind spots and the possibility of highlights and shadows in the image, thereby improving detection accuracy.

[0062] In this embodiment, as Figure 6As shown, the multiple light-emitting areas 201 of the light-emitting element 211 are arranged sequentially in the vertical direction. That is, the detection light emitted by the upper light-emitting area 201 is projected downwards towards the object to be detected 900 in the vertical plane, the detection light emitted by the middle light-emitting area 201 is projected horizontally towards the object to be detected 900 in the vertical plane, and the detection light emitted by the lower light-emitting area 201 is projected upwards towards the object to be detected 900 in the vertical plane.

[0063] In some embodiments, such as Figure 4 As shown, the direction of the detection light corresponding to the light-emitting element 211, projected along the first direction, forms an acute angle with the side of the object to be detected 900 away from the imaging structure 300. For example, the acute angle α = 30°.

[0064] It is understandable that, along the projection of the first direction, the orientation of the detection light corresponding to the light-emitting element 211 forms an acute angle with the side of the object under test 900 away from the imaging structure 300. That is, the detection light is not perpendicular to the surface of the object under test 900, but is irradiated onto the object under test 900 at a certain tilt angle. This can effectively reduce the possibility of reflected light directly entering the imaging structure 300, thereby reducing reflected light interference, reducing the possibility of overexposure or loss of detail in imaging, enhancing the contrast of the surface features of the object under test 900, and improving the imaging quality.

[0065] In some embodiments, such as Figure 2 and Figure 3 As shown, the light-emitting element 211 includes a half-shell 2111 and a plurality of spaced-apart light strips 2112. The half-shell 2111 forms a mounting groove. The light strips 2112 are disposed within the mounting groove, and the side of the light strip 2112 near the groove opening has a plurality of sub-light-emitting areas, which correspond one-to-one with the light-emitting areas 201. The arrangement direction of the light strips 2112 intersects with the first direction. The connection methods between the half-shell 2111 and the mounting bracket 100, and between the half-shell 2111 and the light strips 2112, include, but are not limited to, threaded connection, snap-fit, welding, or plug-in connection. It should be noted that the shape and size of the mounting groove and the number of light strips 2112 can be designed according to actual needs, and this embodiment does not impose specific limitations on them.

[0066] Understandably, the semi-shell 2111 serves to protect and fix the light strip 2112 through the mounting groove. The light strip 2112 extends in the vertical direction and has multiple sub-light-emitting areas. The sub-light-emitting areas of multiple light strips 2112 located at the same height together form the light-emitting area 201, thereby providing uniformity of light distribution.

[0067] In some embodiments, such as Figures 1 to 4As shown, along the projection of the first direction, the orientation of the detection light corresponding to the light-emitting element 211 forms an acute angle with the side of the object to be detected 900 away from the imaging structure 300. In addition, the two light-emitting elements 211 are symmetrically arranged with the axis of symmetry as the center, and the arrangement direction of the light strip 2112 is also set at an acute angle with the axis of symmetry.

[0068] In some embodiments, the light strip 2112 includes a body and a plurality of LED beads spaced apart in the vertical direction, wherein a portion of the plurality of LED beads forms a sub-light-emitting area, thereby enabling independent operation between each light-emitting area 201.

[0069] In some embodiments, such as Figure 9 As shown, the mounting position of the light-emitting element 211 relative to the mounting bracket 100 around the first axis is adjustable. The first axis is parallel to the first direction. The angle α can be adjusted to adapt to various different detection needs, reduce interference from reflected light, and improve the clarity and contrast of the image.

[0070] In some embodiments, such as Figure 9 As shown, the detection device also includes a first connector 410 and a second connector 420. The first connector 410 corresponds to and is connected to the half shell 2111. The second connector 420 is connected to the mounting bracket 100. One of the first connector 410 and the second connector 420 is provided with a first arc-shaped hole, and the other of the first connector 410 and the second connector 420 is provided with a first mounting hole. That is, by screwing the first mounting hole and the first arc-shaped hole at different positions, the angle of the light-emitting element 211 relative to the mounting bracket 100 along the first axis can be adjusted.

[0071] In some embodiments, such as Figure 9 As shown, the distance between the two light-emitting elements 211 is adjustable to change the coverage and intensity of the detection light, thereby adapting to the test pieces 900 of different shapes, sizes and detection requirements.

[0072] In some embodiments, such as Figure 9 As shown, the detection device also includes a third connector 430, which is connected to the mounting bracket 100 and corresponds one-to-one with the second connector 420. One of the third connector 430 and the second connector 420 is provided with at least one first elongated hole extending along the second direction, and the other of the third connector 430 and the second connector 420 is provided with at least one second mounting hole. That is, by screwing the second mounting hole and the first elongated hole at different positions, the distance between the two light-emitting elements 211 can be adjusted by utilizing the adjustable position of the light-emitting element 211 relative to the mounting bracket 100 along the second direction. Of course, in other embodiments, the position of one of the light-emitting elements 211 relative to the mounting bracket 100 along the second direction can also be adjusted; this embodiment does not impose specific limitations on this.

[0073] It should be noted that the second direction, the axis of symmetry, and the first direction intersect each other.

[0074] In some embodiments, such as Figure 9 As shown, the distance between the light-emitting structure 200 and the imaging structure 300 is adjustable to optimize the imaging effect and improve detection accuracy and efficiency.

[0075] In some embodiments, such as Figure 9 As shown, the detection device also includes a fourth connector 440, which is connected to the mounting bracket 100. One of the fourth connector 440 and the third connector 430 is provided with at least one second elongated hole extending along a third direction, and the other of the fourth connector 440 and the third connector 430 is provided with at least one third mounting hole. The third direction is parallel to the axis of symmetry. That is, by screwing the third mounting hole and the second elongated hole at different positions, the two light-emitting elements 211 can simultaneously move closer to or further away from the imaging structure 300 along the third direction, thereby making the distance between the imaging structure 300 and the light-emitting structure 200 along the third direction adjustable.

[0076] In some embodiments, such as Figure 9 As shown, the pose of the imaging structure 300 relative to the mounting bracket 100 is adjustable. That is, the pose includes at least one of position and orientation, in order to adjust the focal length of the imaging structure 300, reduce the possibility of distortion, enhance contrast, ensure image clarity, and improve detection accuracy.

[0077] In some embodiments, such as Figure 9 As shown, the detection device also includes a fifth connector 450, which corresponds to and is connected to the imaging structure 300. At least one of the fifth connector 450 and the mounting bracket 100 is provided with a third elongated hole extending in a third direction, and the other of the fifth connector 450 and the mounting bracket 100 is provided with at least one fourth mounting hole. That is, by screwing the fourth mounting hole and the third elongated hole at different positions, the distance between the corresponding imaging structure 300 and the light-emitting structure 200 in the third direction can be adjusted.

[0078] In some embodiments, such as Figure 9 As shown, the detection device also includes a fifth connector 450, which corresponds to and is connected to the imaging structure 300. At least one of the fifth connector 450 and the mounting bracket 100 is provided with a fourth elongated hole extending along the first direction, and the other of the fifth connector 450 and the mounting bracket 100 is provided with at least one fifth mounting hole. That is, by screwing the fifth mounting hole and the fourth elongated hole at different positions, the mounting position of the corresponding imaging structure 300 relative to the mounting bracket 100 along the first direction can be adjusted.

[0079] In some embodiments, such as Figure 9As shown, the detection device also includes a fifth connector 450, which corresponds to and is connected to the imaging structure 300. At least one of the fifth connector 450 and the mounting bracket 100 is provided with a second arc-shaped hole, and the other of the fifth connector 450 and the mounting bracket 100 is provided with at least one sixth mounting hole. That is, by screwing the sixth mounting hole and the second arc-shaped hole at different positions, the angle of the corresponding imaging structure 300 relative to the mounting bracket 100 around the second axis can be adjusted, and the second axis is parallel to the second direction.

[0080] In some embodiments, such as Figures 7 to 9 As shown, multiple imaging structures 300 are provided, and these multiple imaging structures 300 are sequentially distributed along the first direction to provide detection images from more angles, thereby improving detection efficiency and comprehensiveness. It should be noted that the number and specific distribution of the imaging structures 300 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0081] In some embodiments, such as Figure 7 As shown, the optical axis of the lens of the imaging structure 300 is tilted towards the light-emitting structure 200 along a first direction. It can be understood that by tilting the optical axis of the lens of at least one imaging structure 300 from top to bottom along a third direction towards the light-emitting structure 200 or from bottom to top along a third direction towards the light-emitting structure 200, it is possible to obtain detection images from multiple angles.

[0082] In some embodiments, such as Figure 7 As shown, there are three imaging structures 300. Along the third direction towards the light-emitting structure 200, the lens optical axis of the upper imaging structure 300 is tilted downward, the lens optical axis of the middle imaging structure 300 is parallel to the third direction, and the lens optical axis of the lower imaging structure 300 is tilted upward.

[0083] In some embodiments, such as Figure 8 and Figure 9 As shown, the imaging structure 300 is placed horizontally and spaced apart from the object to be tested 900 along a first direction. The detection device also includes a reflector 500, which is disposed on the mounting bracket 100 and located between the light-emitting structure 200 and the imaging structure 300.

[0084] It is understandable that, while the optical axis of the lens of the imaging structure 300 is parallel to a third direction and offset from the workpiece 900 in the vertical direction, the direction of the optical axis of the lens can be changed by setting the reflector 500 to ensure that the detection image is obtained. At the same time, the spatial layout of the entire detection device can be optimized, making the structure of the entire detection device as compact as possible.

[0085] In some embodiments, such as Figure 8As shown, the optical axes of the lenses of the three imaging structures 300 arranged sequentially from top to bottom are all parallel to the third direction. The imaging structures 300 located at the top and bottom are each equipped with a corresponding reflector 500 to change the corresponding lens optical axis. In some embodiments, such as... Figure 9 As shown, the three imaging structures 300 are arranged sequentially from top to bottom. The lens optical axis of the upper imaging structure 300 is tilted, while the lens optical axes of the middle and lower imaging structures 300 are parallel to a third direction. The lower imaging structure 300 is equipped with a corresponding reflector 500 to change its corresponding lens optical axis. Of course, in other embodiments, the lens optical axis of the lower imaging structure 300 may be tilted, while the lens optical axes of the middle and upper imaging structures 300 may be parallel to a third direction, and the upper imaging structure 300 may be equipped with a corresponding reflector 500 to change its corresponding lens optical axis. This embodiment does not impose specific limitations on this.

[0086] In some embodiments, such as Figure 9 As shown, the angle of the reflector 500 relative to the mounting bracket 100 around the second axis is adjustable to ensure that the optical axis of the lens of the corresponding imaging structure 300 can pass through the test piece 900 after passing through the reflector 500, thereby improving the clarity of the image.

[0087] In some embodiments, such as Figure 9 As shown, the detection device also includes a sixth connector, which is disposed on the fourth connector 440 and rotatably connected to the reflector 500 around the second axis. This means that the angle of the reflector 500 can be adjusted by manually rotating the sixth connector. After adjustment, the reflector 500 and the sixth connector can be fixed relative to each other by tightening screws or nuts to ensure that the reflector 500 is maintained at the desired angle. Of course, in other embodiments, the angle of the reflector 500 can also be electrically adjusted using a motor; this embodiment does not impose specific limitations on this.

[0088] This application also provides a detection method for a detection device, a control device for the detection device, an electronic device, and a readable storage medium, which are described in detail below.

[0089] The detection method of the detection device can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0090] The terminal includes, but is not limited to, portable communication devices such as mobile phones or tablets with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads). It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads).

[0091] The following embodiments describe a terminal including a display and a touch-sensitive surface. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.

[0092] The detection method of the detection device provided in this application embodiment can be executed by an electronic device or a functional module or functional entity in an electronic device that can implement the detection method of the detection device. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablets, computers, cameras and wearable devices. The detection method of the detection device provided in this application embodiment will be described below using an electronic device as the execution subject.

[0093] like Figure 10 As shown, the detection method of the detection device is applied to the above-mentioned detection device, and the detection method of the inspection device includes steps 610 and 620.

[0094] Step 610: Control the multiple light-emitting areas of the light-emitting structure 200 to emit detection light to the object to be tested 900 in sequence, and obtain multiple detection images through the imaging structure 300.

[0095] Understandably, each light-emitting area group works independently to continuously change the brightness and darkness of various locations on the object under test 900, thereby obtaining at least one corresponding detection image, which is beneficial for subsequent processing and analysis of the detection images.

[0096] For example, combined Figure 6 and Figure 7 As shown, the three light-emitting area groups and three imaging structures 300 are distributed sequentially from top to bottom, and each light-emitting area group has two symmetrically arranged beam-splitting areas. That is, a and b, c and d, and e and f form three light-emitting area groups respectively. First, a and b are illuminated synchronously and three detection images are obtained through the three imaging structures 300 respectively. Then, c and d are illuminated synchronously and three detection images are obtained through the three imaging structures 300 respectively. Finally, e and f are illuminated synchronously and three detection images are obtained through the three imaging structures 300 respectively, thus obtaining a total of nine detection images.

[0097] Of course, in other embodiments, the three light-emitting zones may also work sequentially from bottom to top; c and d may also light up individually. This embodiment does not impose specific restrictions on the order in which the light-emitting zones work.

[0098] Step 620: Compare each test image with the reference image to determine whether the test piece 900 is qualified. It should be noted that the reference image is a standard image used for comparison, that is, a test image obtained based on the test piece 900 that has been determined to be qualified.

[0099] Understandably, by comparing the differences between the detected image and the reference image, the degree of matching between the detected image and the reference image is determined, thereby determining whether the item to be detected 900 is qualified. For example, if the degree of matching is greater than a first threshold, the item to be detected 900 is considered qualified; otherwise, the item to be detected 900 is considered unqualified.

[0100] For example, in some embodiments, the reference image may be a single image or a collection of multiple images used to evaluate the quality of the object to be inspected 900. In some embodiments, multiple inspection images may also be stitched together and then compared with the reference image.

[0101] According to the detection method of the detection device provided in the embodiments of this application, multiple light-emitting areas of the light-emitting structure 200 are controlled to emit detection light sequentially, and multiple detection images are obtained by the imaging structure 300. Then, these detection images are compared with reference images to determine whether the test piece 900 is qualified. This realizes multi-angle and multi-directional illumination and imaging, and improves the comprehensiveness and accuracy of detection.

The judgment module 720 compares each detection image with a reference image to determine whether the workpiece 900 to be tested is qualified.
