[0031] like Figures 1 to 3 As shown, an online six-sided automatic pin detection device can automatically and comprehensively detect the pins of a product from multiple directions, which can effectively improve detection accuracy and efficiency while reducing manual detection costs. The detection device in this embodiment includes a chassis 1 and a detection track 2 fixedly installed on the chassis 1. The product can be directly transported to the detection position through the detection track 2 and automatically photographed for detection without manual operation, thereby reducing labor costs.
[0032] like Figure 1 As shown, the chassis 1 of this embodiment is provided with a camera bracket 3 for fixing the camera. The camera bracket 3 surrounds the detection track 2 and is set above the detection track 2, so that the camera installed on the camera bracket 3 can take pictures and detect the detection track 2 from multiple directions.
[0033] Specifically, in this embodiment, the photo-taking bracket 3 is equipped with first side cameras 4 on both sides corresponding to the transport direction of the detection track 2, which can take pictures of the pins on the front and rear sides of the product for detection; the top of the photo-taking bracket 3 is equipped with a top-down camera 5, which is set vertically downward and aligned with the detection track 2, so as to take pictures of the pins on the top surface of the product on the track for detection; in this embodiment, the detection track 2 is equipped with second side cameras 6 on both sides, which are higher than the detection track 2 and take pictures of the left and right sides of the product on the detection track 2 for detection; in addition, in order to take pictures of the bottom surface of the product on the detection track 2, this embodiment has a shooting port 11 at the end face of the chassis 1 corresponding to the detection track 2, and a bottom camera 7 aligned with the shooting port 11 is set in the chassis 1, so that the bottom camera 7 can take pictures of the pins on the bottom surface of the product on the detection track 2 through the shooting port 11.
[0034] This embodiment achieves complete coverage of the detection track 2 through the first side camera 4, the second side camera 6, the overhead camera 5, and the bottom camera 7. This allows for the imaging and detection of the pins of the product on the detection track 2 from six angles: front, back, left, right, top, and bottom. This comprehensive detection function effectively improves the efficiency and accuracy of the detection, and eliminates the need for manual intervention, thus reducing labor costs.
[0035] like Figure 2 and Figure 3 As shown, the detection track 2 in this embodiment includes two parallel transport rails 21 mounted side by side on the chassis 1. The two transport rails 21 are respectively located on both sides of the shooting port 11 to form the detection track 2. A detection fixture 22 is provided between the two transport rails 21, so that the product to be tested can be transported to the detection position for detection through the detection fixture 22. In order to realize the movement of the detection fixture 22, this embodiment provides a drive component 23 at both ends of the transport rail 21. By connecting the detection fixture 22 with the drive component 23, the detection fixture 22 can move along the detection track 2 to enter and exit the detection position under the drive of the drive component 23, so as to realize the photographic detection of the product.
[0036] Specifically, such as Figure 2 and Figure 3As shown, the drive assembly 23 in this embodiment includes a drive roller 231 connecting the two ends of two transport rails 21 and a transport motor 232 connected to any one of the drive rollers 231. The two drive rollers 231 are connected by a transmission chain 233, which is connected to the detection fixture 22. When the transport motor 232 starts and drives any one drive roller 231 to rotate, the other drive roller 231 can rotate along with it, thereby driving the detection fixture 22 to move and realize the transport of the product. In this embodiment, the top of each of the two transport rails 21 is provided with a transport channel 211 arranged along its length, and the two ends of the two drive rollers 231 correspond to the transport channel 211. A transmission gear is provided at the position, and the transmission chain 233 is mounted on the transmission gear on the same side of the two transmission rollers 231 and located in the transport channel 211. The bottom sides of the detection fixture 22 are located on the transport channel 211 and connected to the transmission chain 233 in the transport channel 211. When the transmission roller 231 rotates under the drive of the transport motor 232, the other transmission roller 231 can move together under the action of the transmission chain 233 and the transmission gear, so that the transmission chain 233 moves in the transport channel 211. The movement of the transmission chain 233 drives the detection fixture 22 to move in the detection track 2, thereby realizing the automatic transport of the product to the detection position.
[0037] like Figure 3 As shown, in order to facilitate the photographic inspection of the bottom pins of the product, the bottom camera 7 in this embodiment is set inside the chassis 1 and aligned with the shooting port 11. When the product under test moves to the detection position under the action of the drive component 23 and the detection track 2, the bottom of the product is exactly aligned with the position of the shooting port 11, so that the bottom camera 7 set inside the chassis 1 can take pictures of the bottom pins of the product through the shooting port 11. Specifically, the chassis 1 in this embodiment is provided with a mounting bracket 12, and the bottom camera 7 is fixedly installed on the mounting bracket 12 at the position corresponding to the shooting port 11, thereby realizing the photographing of the bottom of the detection track 2.
[0038] like Figure 1 and Figure 4 As shown, the photographing bracket 3 in this embodiment includes four uprights 31 arranged around the detection track 2 and a horizontal bar 32 arranged above the detection track 2 and connected to each upright 31 to form a square frame. The square frame formed by the combination of the horizontal bar 32 and the uprights 31 surrounds the detection track 2, thereby facilitating the camera mounted on the photographing bracket 3 to photograph the front and back sides of the product. In this embodiment, each of the two horizontal bars 32 corresponding to the transport direction of the detection track 2 is provided with a mounting base 33. The first side camera 4 is fixedly mounted on the mounting base 33 and tilted downwards towards the front and back sides of the detection fixture 22, thereby realizing the detection of the front and back sides of the detection fixture 22.
[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the second side camera 6 is set on one side of the two transport rails 21 that are perpendicular to each other (i.e., the left and right sides of the detection rail 2), and can take pictures of the pins on the left and right sides of the product on the detection fixture 22. In order to accurately detect the pins on the left and right sides of the product, this embodiment sets an XY dual-axis moving mechanism 8 on both sides of the detection rail 2, and the second side camera 6 is fixedly installed on the XY dual-axis moving mechanism 8, so that the position and focal length of the second camera can be adjusted by the XY dual-axis moving mechanism 8 to improve the accuracy of the picture detection.
[0040] like Figure 5 As shown, the XY dual-axis moving mechanism 8 in this embodiment includes an X-axis guide rail 81 arranged along the transport direction of the detection track 2 and a Y-axis guide rail 82 movably mounted on the X-axis guide rail 81 and horizontally perpendicular to the side of the transport track 21. In this embodiment, a movable seat 83 is movably mounted on the Y-axis guide rail 82, and the second side camera 6 is fixedly mounted on the movable seat 83, so that the second side camera 6 can move along the transport direction of the detection track 2 under the action of the X-axis guide rail 81, and at the same time adjust its focus by moving closer to or further away from the detection track 2 under the action of the Y-axis guide rail 82, thereby facilitating comprehensive and accurate imaging of the side of the product and ensuring detection accuracy.
[0041] like Figure 1 and Figure 6 As shown, in this embodiment, the overhead camera 5 is positioned above the photo-taking bracket 3 and vertically facing the detection position of the detection track 2, facilitating the taking of photos of the top surface of the product. To achieve accurate photo-taking detection, the chassis 1 in this embodiment is equipped with a gantry 9 that is higher than the photo-taking bracket 3. At the same time, the top of the gantry 9 is equipped with an XYZ three-axis moving mechanism 91. By fixing the overhead camera 5 to the XYZ three-axis moving mechanism 91, the overhead camera 5 can be adjusted in position under the action of the XYZ three-axis moving mechanism 91, thereby achieving accurate photo-taking detection.
[0042] Specifically, such as Figure 6As shown, the XYZ three-axis moving mechanism 91 of this embodiment includes an X-axis slide rail 911 fixedly installed on the top of the gantry 9, a Y-axis slide rail 912 movably installed on the X-axis slide rail 911, and a Z-axis slide rail 913 movably installed on the Y-axis slide rail 912. Specifically, the X-axis slide rail 911 is arranged along the width direction of the detection track 2 and is perpendicular to the two transport tracks 21. The Y-axis slide rail 912 is horizontally perpendicular to the X-axis track and parallel to the transport direction of the detection track 2. The Z-axis slide rail 913 is vertically connected to the Y-axis slide rail 912. A slide block 914 is movably installed on the Z-axis slide rail 913, and the overhead camera 5 is vertically fixedly installed on the slide block 914. This allows the overhead camera 5 to adjust its left and right position by moving left and right on the X-axis slide rail 911, adjust its front and back position by moving back and forth on the Y-axis slide rail 912, and adjust its focal length by moving up and down on the Z-axis slide rail 913, thereby achieving accurate photographic detection of the pins on the top surface of the product.
[0043] like Figure 1 As shown, in order to improve the clarity of the image and thus improve the accuracy of the inspection, light sources 10 are also provided around the image port 11 and the image holder 3 in this embodiment. Each light source 10 is set towards the inspection track 2, so that when each camera takes a picture of the product on the inspection fixture 22, each light source 10 can illuminate each surface of the product, thereby improving the image effect and thus improving the accuracy of the inspection.
[0044] Specifically, such as Figure 7 As shown, the light source 10 in this embodiment includes a base, a connecting frame, and a fill light. The base is fixedly installed around the shooting port 11 and on the shooting bracket 3. One end of the connecting frame is rotatably connected to the base, and the fill light is fixedly connected to the other end of the connecting frame. This allows the fill light to be adjusted in orientation through the connecting frame to achieve precise fill light, thereby further improving the accuracy of the shooting.
[0045] In summary, the working principle of this embodiment is as follows: By setting a detection track 2 on the chassis 1, the product to be tested can automatically move to the detection track 2 for photographic detection, thus achieving automated detection. Furthermore, by setting a photographic bracket 3 on the chassis 1, and setting a first side camera 4 and a top-view camera 5 on the photographic bracket 3, while setting a second side camera 6 on both sides of the detection track 2 and a bottom camera 7 at the bottom of the chassis 1, the product on the detection track 2 can be photographed and detected from all six sides (front, back, left, right, top, and bottom) by the respective cameras. This realizes the function of multi-faceted detection of the product in this embodiment, which can effectively improve detection accuracy and efficiency, while reducing labor costs.
