[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following is in conjunction with the appendix Figure 1 and Figure 2 The embodiments of this utility model will be described in detail below.

[0028] The detection device of this utility model embodiment includes a detection platform 1, an imaging component 2, and a data processor 3. The imaging component 2 is mounted on the detection platform 1 and includes an imaging element 21 and a scanning element 22. The imaging element 21 is adapted to be arranged opposite to a first surface of the workpiece 100, and the scanning element 22 is arranged opposite to a second surface of the workpiece 100. The scanning direction of the scanning element 22 is orthogonal to the imaging direction of the imaging element 21. The imaging element 21 is used to photograph the workpiece 100, and the scanning element 22 is used to scan the contour of the workpiece 100. The data processor 3 is connected to the imaging element 21 and the scanning element 22. The data processor 3 receives the image captured by the imaging element 21 and the contour scanned by the scanning element 22 in real time, compares the image and contour with pre-stored standard data in the data processor 3, and outputs the detection data of the workpiece 100.

[0029] The detection device of this utility model embodiment uses an imaging element 21 arranged opposite to the first surface of the workpiece 100 to facilitate the imaging element 21 to capture an image of the first surface of the workpiece 100. A scanning element 22 is arranged opposite to the second surface of the workpiece 100, with the imaging direction of the imaging element 21 orthogonal to the scanning direction of the scanning element 22, facilitating the scanning element 22 to scan the contour of the workpiece 100 to obtain a contour image of the workpiece 100. A data processor 3 processes the image of the workpiece 100 captured by the imaging element 21 and the contour image of the workpiece 100 scanned by the scanning element 22, and compares the processed data with pre-stored standard data in the data processor 3 to output the detection data of the workpiece 100, thereby achieving automated detection of the workpiece 100 and improving detection efficiency and quality.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, workpiece 100 is mounted on inspection platform 1, and imaging element 21 is located on the rear side of workpiece 100. The first surface of workpiece 100 is the rear side of workpiece 100. Imaging element 21 takes a picture of workpiece 100 from directly behind and transmits the picture to data processor 3. Data processor 3 extracts the dimensions and cutting angles of the rear side of workpiece 100 from the picture. The dimensions of the rear side of workpiece 100 include the geometric dimensions of the rear side of workpiece 100, the opening size on the rear side of workpiece 100, and the opening spacing. By comparing the data of the dimensions and cutting angles of the rear side of workpiece 100 extracted by data processor 3 with the standard data pre-stored in data processor 3, the detection results of the geometric dimensions of the rear side of workpiece 100 and the opening diameter, hole spacing, and cutting angle on the rear side of workpiece 100 are obtained.

[0031] The scanning element 22 is located above the workpiece 100, and the second surface of the workpiece 100 is the upper side surface of the workpiece 100. The scanning element 22 scans the workpiece 100 from directly above and transmits the scanned contour map to the data processor 3. The data processor 3 compares the contour map scanned by the scanning element 22 with the standard data pre-stored in the data processor 3. By detecting the corner code points at the end of the second surface of the workpiece 100, the presence, depth, size and position of the corner code points are determined, and the accurate comparison and detection of the form and position tolerances of the workpiece 100 is completed. The detection results of the form and position tolerances of the workpiece 100 are output, realizing non-contact measurement of the workpiece 100 and improving the detection efficiency and detection quality of the workpiece 100.

[0032] The detection device in this embodiment achieves fully automated non-contact detection of the workpiece 100 through the imaging element 21, the scanning element 22 and the data processor 3. This improves detection efficiency while ensuring the consistency of detection results, avoiding the inconsistency of detection results caused by subjective judgment and experience differences of staff in related technologies, and thus improving detection quality.

[0033] Optionally, the first surface of the workpiece 100 is the C surface of the workpiece 100, that is, the rear side surface of the workpiece 100, the second surface of the workpiece 100 is the D surface of the workpiece 100, that is, the upper side surface of the workpiece 100, and the front side surface of the workpiece 100 is the A surface of the workpiece 100.

[0034] Optionally, the workpiece 100 is a long strip aluminum alloy profile, such as a door and window frame or a solar panel frame. The holes on the workpiece 100 are stamped holes, and the first surface of the workpiece 100 is the side where the stamped holes are located.

[0035] In some embodiments, the detection device further includes a first light source 41, which is mounted on the detection platform 1 and adjacent to the imaging element 21. The light emitted by the first light source 41 is parallel to the shooting direction of the imaging element 21.

[0036] Specifically, such as Figure 2 As shown, the first light source 41 and the imaging element 21 are located on the same side of the workpiece 100, and the first light source 41 is closer to the workpiece 100 than the imaging element 21. The light emission direction of the first light source 41 is towards the rear side of the workpiece 100, which makes it easier for the first light source 41 to provide a uniform illumination effect for the imaging element 21 to capture images, thereby improving the image quality of the imaging element 21.

[0037] In some embodiments, the detection device further includes a second light source 42, which faces the third surface of the workpiece 100, and the third surface of the workpiece 100 is arranged opposite to the first surface of the workpiece 100.

The second light source 42 is located on the front side of the workpiece 100. The second light source 42 and the first light source 41 are respectively disposed on the two sides of the workpiece 100. By setting the second light source 42 toward the front side of the workpiece 100, the interference of ambient light on the imaging element 21 is reduced, and the imaging quality of the imaging element 21 is further improved.

[0039] In some embodiments, the first light source 41 is a coaxial light source, and the second light source 42 is a background light source. By setting the first light source 41 as a coaxial light source coaxial with the imaging element 21, the reflection on the surface of the workpiece 100 can be reduced, the detailed information on the surface of the workpiece 100 can be clearly displayed, and a stable and high-quality lighting environment can be provided for the imaging element 21, thereby improving the quality and accuracy of the images captured by the imaging element 21, and thus improving the detection accuracy of the detection device.

[0040] By setting the second light source 42 as a background light source, the contrast between the workpiece 100 and the background can be enhanced, the outline of the workpiece 100 can be clearly highlighted, and the shape and boundary of the workpiece 100 can be more obvious during the shooting process. This helps the imaging element 21 to generate a clearer image, thereby improving the imaging quality of the imaging element 21 and thus improving the detection accuracy of the detection device.

The mounting base 5 facilitates the installation of the imaging element 21, scanning element 22, first light source 41, and second light source 42, while simultaneously enabling synchronous movement of these elements in the first direction, thereby improving detection efficiency.

[0043] Optionally, such as Figure 2 As shown, the mounting base 5 includes a first mounting portion 51, a second mounting portion 52, a third mounting portion 53, and a fourth mounting portion 54. The first mounting portion 51 extends in the front-to-back direction and is used to mount the imaging element 21 so that the imaging element 21 can capture images of the workpiece 100 from behind. The second mounting portion 52 extends in the vertical direction, and its lower end is connected to the front end of the first mounting portion 51. The second mounting portion 52 is used to mount the first light source 41. The third mounting portion 53 extends in the front-to-back direction, and its rear end is connected to the upper end of the second mounting portion 52. The third mounting portion 53 is used to mount the scanning element 22 so that the scanning element 22 is mounted directly above the workpiece 100. The fourth mounting portion 54 extends in the vertical direction, and its upper end is connected to the front end of the third mounting portion 53. The fourth mounting portion 54 is used to mount the second light source 42.

[0044] Optionally, the second mounting part 52 is provided with a through hole that passes through the second mounting part 52. The through hole is arranged opposite to the imaging element 21, so that the imaging element 21 can take pictures of the workpiece 100 through the through hole.

[0045] In some embodiments, the detection device further includes a drive assembly 6, which includes a guide rail 61 and a drive member. The guide rail 61 extends along a first direction and is mounted on the detection platform 1. The mounting base 5 is mounted on the guide rail 61, and the drive member is connected to the mounting base 5 to drive the mounting base 5 to move on the guide rail 61.

[0046] Specifically, such as Figure 2 As shown, guide rail 61 is mounted on inspection platform 1, extending in the left-right direction. When workpiece 100 is placed on inspection platform 1, guide rail 61 is parallel to workpiece 100 and located in front of guide rail 61. Mounting base 5 is movably mounted on guide rail 61. Driving component is used to drive mounting base 5 to move in the left-right direction, facilitating imaging component 21 and scanning component 22 to capture and scan different positions of workpiece 100, realizing dynamic capturing and scanning of workpiece 100.

[0047] Optionally, the driving component is a linear motor to ensure that the mounting base 5 moves smoothly back and forth on the guide rail 61.

Any structure that can drive the mounting base 5 to move on the guide rail 61 is within the protection scope of this embodiment.

[0048] In some embodiments, the detection device further includes a support 7, which is mounted on the detection platform 1 and located between the imaging element 21 and the second light source 42. The support 7 is used to place the workpiece 100.

[0049] Specifically, such as Figure 2 As shown, the support 7 is installed on the detection platform 1. The support 7 and the guide rail 61 are arranged at intervals in the front-back direction, and the support 7 is located on the front side of the guide rail 61. The setting of the support 7 makes it easy to determine the placement position of the workpiece 100, and thus facilitates the imaging element 21 and the scanning element 22 to take pictures and scan the workpiece 100.

[0050] Optionally, there are multiple supports 7, which are arranged at intervals in the left and right directions.

When not using the testing device, the dust door 81 is closed to improve the dustproof performance of the testing device. Figure 1 The structure of part of the dust cover 8 is hidden to make it easier to see the imaging component 2 above the detection platform 1.

[0052] In some embodiments, the imaging element 21 is an industrial camera; and / or, the scanning element 22 is a 3D contour scanner.
