Description

Technical Field

[0001] This utility model mainly relates to the field of automated visual inspection equipment technology, specifically to a high-speed production line defect detection device equipped with a linear CCD with deep learning. Background Technology

[0002] In the field of product defect detection on high-speed production lines, traditional inspection equipment faces many technical bottlenecks. On the one hand, most inspection devices use fixed-view linear CCD cameras, which can only inspect products in a single direction. This makes it difficult to adapt to product position shifts or complex curved surfaces on the production line, resulting in a large number of blind spots and failing to meet the requirements for high-precision inspection. On the other hand, the adjustment mechanisms of existing equipment rely heavily on complex electronic control systems and sensor feedback. This not only increases equipment costs and maintenance difficulty, but also makes electronic control components prone to failure in industrial environments with strong electromagnetic interference and high dust levels. This results in poor detection stability and insufficient real-time performance, making it difficult to match the operating rhythm of high-speed production lines.

[0003] In addition, the light source systems of some devices lack targeted adjustment functions and cannot provide suitable lighting according to the material and color characteristics of the product, resulting in poor image acquisition quality and affecting the accuracy of defect identification. At the same time, the limitations of the mechanical structure design make it difficult for the detection device to quickly adapt to the detection needs of different product specifications. When changing product models on the production line, a lot of time needs to be spent re-adjusting the equipment, which seriously restricts production efficiency. There is an urgent need for a new type of detection device that takes into account cost, stability and detection accuracy.

[0031] See attached document Figure 1-5 The high-speed production line defect detection device equipped with a deep learning-based linear CCD includes a horizontal rotating base 1, a telescopic cantilever 2, and a dynamic tracking support assembly. The dynamic tracking support assembly includes a pitch adjustment mechanism 3, a linear CCD camera 4, and a coaxial light source group 5. The telescopic cantilever 2 includes a hydraulic telescopic sleeve 201, with a telescopic arm 202 horizontally arranged at the upper end of the hydraulic telescopic sleeve 201. A telescopic arm 203 is connected to the end of the telescopic arm 202. The telescopic arm 203 is connected to the end of the telescopic arm 202 via a rotary motor 204. The pitch adjustment mechanism 3 includes a U-shaped mounting bracket 301 connected to the telescopic arm 203. The U-shaped mounting bracket 301 contains a pitch adjustment arm 302 and an adjustment drive mechanism 303. A position sensor 6 and a speed sensor 7 are respectively arranged at the upper and lower ends of the linear CCD camera 4.

[0032] The lower end of the hydraulic telescopic sleeve 201 achieves axial rotation via the horizontal rotating seat 1. The upper end of the hydraulic telescopic sleeve 201 is provided with a positioning sleeve 205. Both the upper end of the positioning sleeve 205 and the lower end of the hydraulic telescopic sleeve 201 are provided with limit seats 206. Guide rods 207 are installed through the two limit seats 206. The hydraulic telescopic sleeve 201 serves as the basic support component of the telescopic cantilever 2. It achieves vertical telescopic movement through the hydraulic system, thereby changing the height position of the linear CCD camera 4. The guide rod 207 on one side of the hydraulic telescopic sleeve 201 is positioned by the two limit seats 206. The lower end of the guide rod 207 is fixedly connected to the limit seat 206, and the upper end is movably connected through the limit seat 206, which serves as a guide when the hydraulic telescopic sleeve 201 telescopics. The axial rotation angle of the guide rod 207 is limited by two limit baffles 8 set on the upper surface of the horizontal rotating seat 1. The two limit baffles 8 are detachable and can be used to limit the installation angle according to the inspection requirements of the high-speed production line.

[0033] The telescopic arm 202 has multiple sets of adjustment holes 2021. After being fixed by the adjustment holes 2021, the telescopic arm 202 is embedded in the positioning sleeve 205. The horizontally positioned telescopic arm 202 can extend and retract in the horizontal direction. By selecting different adjustment holes 2021 for fixing, the position of the telescopic arm 202 on the positioning sleeve 205 can be precisely adjusted, further expanding the horizontal detection range. The telescopic arm 203 is vertically set at the end of the telescopic arm 202, and its upper end is connected to the drive end of the rotary motor 204. The rotary motor 204 provides the telescopic arm 203 with a rotation function, so that the telescopic arm 203 can rotate around the connection point, thereby adjusting the horizontal angle of the linear CCD camera 4 to adapt to the detection requirements of different positions and angles. The end of the telescopic arm 203 is provided with a positioning plate 208 fixedly connected to the U-shaped mounting bracket 301. The positioning plate 208 ensures a stable connection between the telescopic arm 203 and the U-shaped mounting bracket 301, ensuring the stability of the entire structure.

[0034] The pitch adjustment mechanism 3 is used to precisely adjust the pitch angle of the linear CCD camera 4 to adapt to product inspection requirements at different heights and tilt angles. The driving end of the adjustment drive mechanism 303 is provided with an extension rod 3031 that passes through the U-shaped mounting bracket 301. The extension rod 3031 is provided with a drive gear 3032. The adjustment drive mechanism 303 can be a gear transmission mechanism driven by a motor. When the adjustment drive mechanism 303 is working, the drive gear 3032 will rotate together with the extension rod 3031. The pitch adjustment arm 302 includes a semi-toothed ring 30 21 and mounting plate 3022, half tooth ring 3021 meshes with drive gear 3032. The two sides of mounting plate 3022 are rotatably connected to the ear plate at the front end of U-shaped mounting bracket 301 through pin shaft 3023 and linkage plate 3024. When drive gear 3032 rotates, because half tooth ring 3021 meshes with drive gear 3032, half tooth ring 3021 will drive mounting plate 3022 to rotate around pin shaft 3023. By adjusting the rotational motion of drive mechanism 303, the pitch angle adjustment of line scan CCD camera 4 can be realized.

[0035] The line-scan CCD camera 4 is used to collect image information of products on the high-speed production line. The line-scan CCD camera 4 is equipped with a position sensor 6 and a speed sensor 7 at its upper and lower ends, respectively. The position sensor 6 is used to monitor the position information of the line-scan CCD camera 4 in real time, and the speed sensor 7 is used to monitor the movement speed of the line-scan CCD camera 4. The data collected by the sensors is fed back to the control system equipped with the device so that the control system can accurately control the telescopic cantilever 2 and the pitch adjustment mechanism 3 according to the actual situation, so as to ensure that the line-scan CCD camera 4 can accurately detect the products and realize dynamic tracking.

[0036] The coaxial light source group 5 is located at the front end of the linear CCD camera 4, and is fixedly connected to the pin shaft 3023 on both sides by the strip positioning plate 9. The coaxial light source group 5 includes a ring LED light source 501 and a light guide plate 502. The ring LED light source 501 is fitted around the lens of the linear CCD camera 4 and fixed to the front end of the strip positioning plate 9 by a buckle. The ring LED light source 501 is a detachable structure and includes three wavelength modules: ultraviolet (365nm), blue light (450nm), and white light (5500K). Each module is connected to the light guide plate 502 through a magnetic interface. The light guide plate 502 covers the light-emitting surface of the light source. The coaxial light source group 5 provides uniform illumination conditions for the linear CCD camera 4, which helps to improve the quality of image acquisition. The coaxial light source group 5 can move synchronously with the pitch angle adjustment of the linear CCD camera 4 to ensure that the illumination direction is consistent with the camera shooting direction, thereby better meeting the detection needs of different angles.

[0037] In this embodiment, the method for adjusting the position and angle of this device is as follows:

[0038] Height adjustment: Activate the hydraulic system to make the hydraulic telescopic sleeve 201 extend and retract vertically, and adjust the height of the line array CCD camera 4 according to the detection requirements of the high-speed production line. The guide rod 207 ensures the stability and accuracy during the movement.

[0039] Horizontal position adjustment: By selecting different adjustment holes 2021 on the telescopic arm 202 for fixing, the position of the telescopic arm 202 on the positioning sleeve 205 is finely adjusted to change the horizontal position of the detection.

[0040] Horizontal angle adjustment: Start the rotary motor 204 to drive the telescopic arm 203 to rotate around the connection point, and adjust the horizontal angle of the linear CCD camera 4 to adapt to the detection requirements of different positions;

[0041] Pitch angle adjustment: Start the adjustment drive mechanism 303, drive the gear 3032 to rotate, drive the half gear ring 3021 to make the mounting plate 3022 rotate around the pin shaft 3023, thereby adjusting the pitch angle of the line array CCD camera 4 to adapt to product inspection at different heights and inclinations.

[0042] In summary, this inspection device achieves significant benefits through the collaborative design of multiple components. The telescopic cantilever and the horizontal rotating base work together to flexibly adjust the inspection height, horizontal position, and angle, expanding the inspection range. The pitch adjustment mechanism precisely controls the camera's pitch angle to adapt to the inspection needs of different products. Position and speed sensors provide real-time feedback to ensure inspection accuracy. The coaxial light source group provides stable illumination, improving image quality. The coordinated operation of all components enables efficient and accurate inspection of product defects on high-speed production lines, effectively ensuring product quality and reducing the cost and error of manual inspection.

[0043] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
