Description

Technical Field

[0001] This utility model belongs to the field of blade inspection, and in particular relates to a blade inspection device. Background Technology

[0002] In today's manufacturing industry, blades are a key component widely used in many fields such as machining, woodworking, food processing, and medical applications. Their quality and performance directly affect the quality of the final product and production efficiency. With the continuous development of the manufacturing industry and the increasing advancement of technology, the requirements for blade quality testing are also becoming increasingly stringent.

[0003] Currently, most blade inspection methods employ a vision inspection camera that is aligned directly with the blade. This method utilizes advanced image recognition technology to quickly and accurately acquire information such as the blade's appearance features, dimensional accuracy, and surface defects, significantly improving inspection efficiency and accuracy. Determining the camera's position by specifying its mounting location is a common practice. During the equipment manufacturing stage, the camera's mounting position is pre-set to ensure precise alignment with the blade after assembly, achieving optimal imaging results for inspection.

[0004] However, unavoidable errors exist in the machining process. Although the installation position is carefully preset during manufacturing, the accumulation of machining errors after actual assembly will still cause deviations between the actual installation position and the preset position of the camera. These deviations may manifest as horizontal, vertical, or angular offsets. Even minute deviations can significantly affect the imaging performance of the visual inspection camera. Camera positional deviations may result in incomplete imaging of the blade in the image, with some critical areas failing to be effectively captured, thus missing important inspection information. Positional deviations may also cause image distortion, affecting the accuracy of dimensional measurements and the reliability of defect identification, making it difficult to obtain optimal imaging results, and consequently reducing the accuracy and reliability of the inspection.

The bracket 2, material placement component 4, robotic arm 3, placement seat 9, and third adjustment component 10 are all fixed to the base 1. The placement seat 9 is located between the material placement component 4 and the third adjustment component 10. The third vision inspection camera 11 is installed on the third adjustment component 10. The gripping end of the robotic arm 3 is located above the material placement component 4, the placement seat 9, and the third vision inspection camera 11. The bracket 2 is fixed with the first adjustment component 5 and the second adjustment component 7. The first vision inspection camera 6 is installed on the first adjustment component 5, and the second vision inspection camera 8 is installed on the second adjustment component 7. The first vision inspection camera 6 is located above the material placement component 4, and the second vision inspection camera 8 is located above the placement seat 9. In use, the blades are placed on a tray via the placement component 4. The position of the blades is determined by the first vision inspection camera 6, and then the robotic arm 3 picks up the blades and places them on the placement seat 9. The size of the blades is then detected by the second vision inspection camera 8. After detection, the robotic arm 3 picks up the blades and moves them to the next station. During this process, the blades pass through the detection range of the third vision inspection camera 11, which identifies the shape and angle of the blades. The robotic arm 3 then rotates the blades to ensure that the angle of each blade remains consistent when placed at the next station. Through the settings of the first adjustment component 5, the second adjustment component 7, and the third adjustment component 10, the positions of the first vision inspection camera 6, the second vision inspection camera 8, and the third vision inspection camera 11 are continuously adjusted and tested during installation until the optimal imaging effect is obtained. Once these three cameras are in their current positions, the installation is complete. Thus, by setting the first adjustment component 5, the second adjustment component 7, and the third adjustment component 10, and by performing adjustment tests after leaving the factory, the best imaging effect can be obtained, thereby achieving good detection accuracy and solving the error problem caused by traditional structural machining.

[0036] The first adjustment assembly 5 and the third adjustment assembly 10 have the same structure, both including: a base plate 12, a column 13, a support clamp 14, a cross column 15, a first mounting base 16, a first positioning pin 17, a first mounting plate 18, and a first screw 19.

Then, the X-axis linear module 41 resets and moves the material tray 43 to the blade waiting station. The robot arm 3 takes the blades from the material tray 43. The limiting block 44 limits one end of the material tray 43, and then the telescopic cylinder 45 extends to drive the stop block 46 to approach the other end of the material tray 43 until the material tray 43 is clamped and fixed.

[0039] The second adjustment component 7 includes a slide cylinder 71, a first dovetail slide 72, a second mounting base 73, a second positioning pin 74, a second mounting plate 75, and a second screw 76. The slide cylinder 71 is fixed to the bracket 2. The sliding end of the slide cylinder 71 is fixed to the first dovetail slide 72.

Specifically, the robotic arm 3 picks up two blades from the material tray 43 and places them side by side on the placement seat 9. The second vision inspection camera 8 performs dimensional inspection on one of the blades. After inspection, the slide cylinder 71 moves the second vision inspection camera 8 to directly above the other blade for inspection. Simultaneously, the robotic arm 3 removes the inspected blade from the placement seat 9 and picks up another blade from the material tray 43 and places it on the placement seat 9, thus achieving efficient blade inspection. The vertical position of the second vision inspection camera 8 is adjusted by the first dovetail slide 72. The angle of the second vision inspection camera 8 can be adjusted by the cooperation of the second mounting plate 75, the second screw 76, the second arc-shaped hole 79, and the second threaded groove 77. The second positioning pin 74 provides a precise fixed point for the rotation of the second mounting plate 75, allowing the second mounting plate 75 to rotate around this defined point during adjustment, thus ensuring its positional accuracy in different adjustment states. Furthermore, the position and angle of the second vision inspection camera 8 can be adjusted easily through simple operation.

The first optical glass 92 is installed in the mounting groove 93. It also includes a second dovetail slide 26, an extension frame 27, and a second light source 28. The second dovetail slide 26 is fixed to the base 1. The sliding end of the second dovetail slide 26 is fixed to the extension frame 27. The second light source 28 is fixed to the extension frame 27 and is located below the first optical glass 92. The position of the second light source 28 can be adjusted up and down using the second dovetail slide 26. Combined with the setting of the second adjustment component 7, the optimal imaging effect can be obtained through adjustment. Placing the second light source 28 below the first optical glass 92 allows it to provide uniform and stable illumination to the blade through the first optical glass 92. Uniform illumination avoids uneven lighting on the blade surface, ensuring a clear and complete image of the blade acquired by the second vision inspection camera 8. This facilitates accurate detection of surface features and dimensional precision, reducing detection errors and misjudgments caused by uneven illumination. Furthermore, the first optical glass 92 provides a flat and stable support platform for the blade, ensuring it remains horizontal and in a fixed position during inspection, which is beneficial for precise positioning and measurement by the second vision inspection camera 8.
