The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0025] This application provides an inspection device to solve the problem of accurately photographing and inspecting products from multiple angles. The following description will be provided in conjunction with the accompanying drawings.

[0026] In the embodiments of this application, such as Figure 1 As shown, the inspection device includes: Support adjustment components are used to achieve self-adjustment: Support 4, movably mounted on the support adjustment component; and, The shooting component 5 is mounted on the bracket 4 and is used to shoot the target product. The shooting component 5 includes a plurality of shooting devices 51, at least one of which is movably mounted on the bracket 4.

[0027] It should be noted that the support and adjustment component refers to a structure capable of changing its own shape and supporting the bracket 4 and the imaging component 5. This shape change can be achieved through multiple movable robotic arms. The bracket 4 can be rotatably or slidably mounted on the support and adjustment component, and the imaging device 51 can be rotatably or slidably mounted on the bracket 4. The target product can be a product to be inspected or a product that has already been inspected.

[0028] It is understandable that the support adjustment component, bracket 4, and camera 51 can be adjusted to different degrees. By sequentially making coarse, fine, and precision adjustments to the support adjustment component, bracket 4, and camera 51, the lens of the camera 51 can be adjusted to the target shooting area of ​​the product under inspection, thus meeting the multi-angle and high-precision shooting requirements of the product under inspection.

[0029] In some embodiments, such as Figure 2 as well as Figure 3 As shown, multiple cameras 51 are arranged sequentially along the first direction. Along the direction in which the multiple cameras 51 are arranged, the cameras 51 located on both sides are slidably connected to the bracket 4. The sliding direction of the cameras 51 located on both sides is set along the first direction.

[0030] It should be noted that the two outermost cameras 51 can move closer to or further apart from each other along the first direction, and can slide synchronously or independently.

[0031] Understandably, multiple cameras 51 are arranged in the same row. The two cameras 51 located on the far sides of the same row can slide relative to the bracket 4. This not only changes the maximum shooting range of the shooting component 5, but also allows for the selection of one of the cameras 51 to adjust the shooting angle without adjusting the support adjustment component and the bracket 4, thus providing greater operational flexibility.

[0032] In some embodiments, such as Figure 3 As shown, the inspection device also includes a synchronous pulley assembly, which includes a synchronous belt 6, two synchronous pulleys 7 tensioned and connected to the synchronous belt 6, and a drive source 8. The drive source 8 is used to drive one of the synchronous pulleys 7 to rotate, and the synchronous belt 6 and the other synchronous pulley 7 move accordingly. The cameras 51 located on both sides are connected to the synchronous belt 6 on both sides of the synchronous pulley 7, and the synchronous belt 6 drives the cameras 51 located on both sides to move closer to or further away from each other.

[0033] It should be noted that the synchronous belt 6 is fitted onto the two synchronous pulleys 7 and is in a taut state. "The two outermost camera devices 51 are connected to the synchronous belt 6 on both sides of the synchronous pulleys 7" means that the synchronous belt 6 is divided into two parts by the two synchronous pulleys 7 both at rest and in motion. Depending on the installation method, these two parts can be arranged vertically or horizontally. Therefore, by placing the two synchronous pulleys 7 on the upper and lower parts of the synchronous belt 6 respectively, the two outermost camera devices 51 can move closer or further apart when the synchronous belt 6 rotates forward or backward. The drive source 8 can be a motor.

[0034] It is understandable that the shooting component 5 is driven to slide synchronously on the bracket 4 by the synchronous belt pulley group, and the weight of the shooting component 5 is supported by the slide rail or slide groove on the bracket 4.

[0035] In some embodiments, such as Figure 1 as well as Figure 4 As shown, the support adjustment component includes a support member 1 and an adjustment member 2, with the adjustment member 2 movably disposed between the bracket 4 and the support member 1.

[0036] It should be noted that support component 1 serves to support adjustment component 2, bracket 4, and shooting assembly 5. Support component 1 can be stably installed by fixing it to a flat working surface. Adjustment component 2 can adjust its own posture, specifically through multiple interconnected robotic arms.

[0037] It is understandable that by controlling the adjustment component 2 to move as a whole with respect to the support component 1 and the bracket 4, the adjustability of the inspection device is improved, so as to better meet the needs of multi-angle shooting inspection.

[0038] In some embodiments, such as Figure 4 As shown, the support member 1 includes a base 11 and a base platform 12. The base platform 12 is rotatably connected to the upper end of the base 11, and the rotation axis of the base platform 12 is set along the direction of gravity.

[0039] It should be noted that when the inspection device is installed and used, the rotation axis of the base 12 is set along the direction of gravity, and the base 12 is located above the base 11.

[0040] It is understood that by rotating the base 12, the overall orientation of the imaging component 5 on the adjusting member 2 can be changed at a large angle within a 360° range, which is beneficial for the inspection device to quickly and flexibly adapt to the position of the product to be inspected. For example, a motor is provided on the base 12 to realize rotation on the base 11.

[0041] In some embodiments, such as Figure 4 as well as Figure 5As shown, the adjusting component 2 is rotatably equipped with an adapter 3, and the bracket 4 is rotatably connected to the adapter 3. The axis of rotation between the adapter 3 and the adjusting component 2 is perpendicular to the axis of rotation between the bracket 4 and the adapter 3.

[0042] Understandably, after the base 12 and the adjusting component 2 have achieved large-angle adjustments, the adapter 3 can change its posture in two dimensions, enabling the imaging component 5 to be adjusted within a small range to get closer to the target imaging area of ​​the product to be inspected.

[0043] Specifically, one end of the adjusting component 2 is provided with a U-shaped groove, and the adapter 3 is rotatably connected to the opposite side wall of the U-shaped groove. The opening of the U-shaped groove is used to avoid the movement of the adapter 3. The adapter 3 can drive the imaging component 5 to reciprocate to cover the upper and lower areas and the left and right areas of the product to be inspected. The adapter 3 can have a built-in motor to realize the rotation of the adjusting component 2.

[0044] In some embodiments, such as Figure 1 as well as Figure 4 As shown, the adjusting member 2 includes an adapter arm 22 and a first mechanical arm 21 and a second mechanical arm 23 movably disposed at both ends of the adapter arm 22. The first mechanical arm 21 and the second mechanical arm 23 are located on adjacent sides of the adapter arm 22 and are movably connected to the base 12 and the adapter 3, respectively.

[0045] It should be noted that "the first robotic arm 21 and the second robotic arm 23 are located on adjacent sides of the adapter arm 22" means that the first robotic arm 21 and the second robotic arm 23 form an L-shape. By changing the extension direction of the adjusting member 2 through the adapter arm 22, the adjusting member 2 can achieve positional changes in different directions. The first robotic arm 21 or the second robotic arm 23 can be slidably or rotatably connected to the base 12, and the same applies to the adapter 3.

[0046] It is understood that the attitude adjustment of the adjusting member 2 is achieved by the movement of the first robotic arm 21 and the second robotic arm 23 relative to the adapter arm 22. For example, the adapter arm 22 is equipped with two motors to realize the rotation of the first robotic arm 21 and the second robotic arm 23 respectively.

[0047] In some embodiments, such as Figure 4 As shown, one end of the first robotic arm 21 is rotatably connected to the base 12, and the two ends of the adapter arm 22 are rotatably connected to the other end of the first robotic arm 21 and one end of the second robotic arm 23, respectively. The other end of the second robotic arm 23 is rotatably connected to the adapter 3. The axis of rotation between the first robotic arm 21 and the base 12 is perpendicular to the axis of rotation between the base 12 and the base 11, and the axis of rotation between the adapter arm 22 and the first robotic arm 21 is also perpendicular to the axis of rotation between the adapter arm 22 and the first robotic arm 21.

[0048] Understandably, by setting rotating axes located in different dimensions, the inspection device achieves a high degree of adjustment flexibility. Specifically, a motor driving the first robotic arm 21 to rotate is mounted on the base 12. Specifically, a U-shaped groove is provided at the end of the second robotic arm 23 away from the adapter arm 22.

[0049] In some embodiments, such as Figure 3 As shown, the multiple cameras 51 are black and white cameras and color cameras, respectively.

[0050] It should be noted that a black-and-white camera is a camera that outputs black-and-white grayscale signals and does not retain the color information of light. In this embodiment, the inspection is mainly carried out on the panel to be inspected. The black-and-white camera is used to take pictures when the panel displays red, green, blue, white, black, and gray images to detect defects such as point, line, and surface defects. The panel photographs taken by the color camera in this embodiment are used to show the non-uniform optical anomalies present in the panel.

[0051] It is understandable that using black-and-white and color cameras to capture the image display of the panel under inspection under different testing conditions facilitates multiple tests on the panel.

[0052] For example, three cameras 51 are arranged sequentially along the first direction, with the color camera located between the two black and white cameras.

[0053] In some embodiments, such as Figure 4 as well as Figure 5 As shown, the bracket 4 is slidably connected to a slide block 41. There are two slide blocks 41, which are respectively connected to the cameras 51 located on the two outermost sides. The inspection device also includes multiple adjusting screws. Each slide block 41 has at least one adjusting screw on different sides. The adjusting screws connect the slide block 41 and the corresponding camera 51.

[0054] It should be noted that the adjusting screw is a mechanical fastener used to fix, position or adjust the relative position of the camera 51 and the bracket 4. The installation position of the camera 51 can also be finely adjusted by turning the adjusting screw. After it is adjusted to the correct position, it can be locked with a nut. Alternatively, a known adjusting screw locking structure can be used.

[0055] Understandably, after the base 12, adjustment component 2, and bracket 4 move the shooting component 5 to align with the target shooting area, the adjustment screw can be further turned to fine-tune the individual shooting unit 51, thereby improving the accuracy of the image shooting.

[0056] In some embodiments, the movements of the base 12, the first robotic arm 21, the adapter arm 22, the second robotic arm 23, the adapter 3, the support 4, and the synchronous pulley assembly are all controlled automatically by electrical signals. This allows for multi-angle, high-precision imaging and detection without human intervention.

[0057] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0058] The inspection device provided in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
