[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: an automated inspection device for small finished parts, comprising a base 1, a fixed seat 2 fixedly connected to the top of the base 1, and two guide mechanisms 3 symmetrically arranged on both sides of the fixed seat 2 above it. Because of the guide mechanisms 3, the guide mechanisms 3 can automatically correct the position of the parts, reducing the workload of manual adjustment of the parts' positions, improving production efficiency, reducing labor costs, and avoiding errors and instability that may be caused by manual operation, ensuring the continuity and consistency of production. The guide mechanism 3 includes a fixed plate 301, which is connected to the fixed seat 2. Two fixed sleeves 302 are symmetrically fixedly installed on the top of the fixed plate 301. A slide rod 303 is slidably connected to the inner wall of the sleeve 302. A compression spring 304 is sleeved on the outer wall of the protruding part of the slide rod 303. Through the cooperation between the slide rod 303 and the compression spring 304, when the part passes between the two guide belts 307, the guide belts 307 will cause the slide rod 303 to slide within the fixed sleeve 302. The slide rod 303 squeezes the compression spring 304, and the elastic force of the compression spring 304 will cause the slide rod 303 and the guide belt 307 to reset, thereby pushing the part back to the center line position of the conveyor belt 9. This design can ensure that the part always stays in the correct position during the subsequent inspection and classification process, avoiding inaccurate inspection or classification errors due to position deviation, and improving the inspection accuracy and classification accuracy of the equipment.

[0019] Two guide wheels 305 are rotatably connected to both ends of the slide bar 303. Two drive wheels 306 are symmetrically rotatably connected to the top of the fixed base 2 on the outside of the two fixed sleeves 302. Because of the drive wheels 306, the control motor 308 controls the drive wheels 306 to rotate. The drive wheels 306 drive the guide belt 307 to rotate on the outer wall of the four guide wheels 305 and the other drive wheel 306. The rotation of the guide belt 307 can assist the conveyor belt 9 in conveying parts and avoid the situation where the parts are too large and get stuck between the two guide belts 307. The outer wall of the two drive wheels 306 and the outer wall of the four guide wheels 305 are fitted with the guide belt 307. The bottom of the fixed plate 301 is fixedly installed with the control motor 308. The output end of the control motor 308 is connected to one of the drive wheels 306.

[0020] A support bracket 4 is fixedly installed on the top of the fixed base 2, located on one side of the guide mechanism 3. The support bracket 4 has a U-shaped design, and a camera 5 is fixedly installed on the inner wall of the support bracket 4 at its center. Because the camera 5 is equipped with a high-resolution industrial camera and multi-angle light source, it can clearly capture images of the surface of the parts. Combined with deep learning algorithms, it can quickly and accurately identify defects on the surface of the parts. Compared with traditional manual inspection, this advanced inspection method can detect more subtle defects, and the inspection speed is faster and the false judgment rate is lower. A data processor 6 is fixedly installed on the top of the support bracket 4. The data processor 6 is connected to the camera 5. Through the cooperation of the data processor 6 and the camera 5, the inspection results captured by the camera 5 can be uploaded to the data processor 6 in real time. The data processor 6 compares the preset model to classify each part, which is convenient for subsequent classification processing.

[0021] Two conveyor rollers 7 are symmetrically rotatably connected between the inner walls of the fixed base 2. A conveyor belt 9 is provided on the outer wall of each conveyor roller 7. An output motor 8 is fixedly installed on one side of the fixed base 2, and its output end is connected to one of the conveyor rollers 7. The height of the guide belt 307 matches the height of the conveyor belt 9. The camera 5 faces the conveyor belt 9. Three support plates 10 are fixedly installed on the upper side of the fixed base 2, arranged in a crisscross pattern. Multi-stage telescopic rods 11 are fixedly installed on the outer wall of each support plate 10. A push plate 12 is fixedly connected to the end of each telescopic rod 11, and the height of the push plate 12 is flush with the height of the conveyor belt 9. A discharge port 13 is provided on the side opposite to the push plate 12. A guide plate 14 is fixedly installed on the outer wall of the fixed base 2 at the discharge port 13. The guide plate 14 is inclined. Through the cooperation between the multi-stage telescopic rod 11 and the push plate 12, the multi-stage telescopic rod 11 extends, which can smoothly push the parts from the conveyor belt 9 to the discharge port 13. The height matching design avoids the parts from falling or getting stuck due to height difference during the pushing process, ensuring the stability and reliability of the pushing action. At the same time, the inclined guide plate 14 can guide the parts to slide out smoothly from the discharge port 13, further improving the efficiency and accuracy of classification and collection.

[0022] The working principle of this utility model is as follows: When using this equipment, the output motor 8 drives the conveyor roller 7 to rotate, and the conveyor roller 7 drives the conveyor belt 9 to rotate. After the parts are sorted, they are placed above the conveyor belt 9 for conveying. During the conveying process, the parts first pass between two guide mechanisms 3. The control motor 308 in the guide mechanism 3 drives one of the drive wheels 306 to rotate, thereby causing the guide belt 307 to rotate on the outer wall of the four guide wheels 305. The guide wheels 305 assist the conveyor belt 9 in conveying the parts. When the part is misaligned, the part squeezes the guide belt 307. The guide belt 307 drives the slide bar 303 to slide within the fixed sleeve 302. During the sliding process, the slide bar 303 will squeeze the compression spring 304. After being squeezed, the compression spring 304's elasticity drives... The slide bar 303 and guide belt 307 are reset, allowing the guide belt 307 to correct the position of the part, moving the part to the center line position of the conveyor belt 9. During the part conveying process, the camera 5 uses a high-resolution industrial camera and multi-angle light source, combined with deep learning algorithm to identify surface defects and take pictures of the part. The images are uploaded to the data processor 6, which compares the results with the preset model. When the part moves with the conveyor belt 9 to different positions of the multi-stage telescopic rods 11, the data processor 6 classifies them according to the detection results and controls the multi-stage telescopic rods 11 to extend. The multi-stage telescopic rods 11 extend rapidly, driving the push plate 12 to push the part on the conveyor belt 9 to the corresponding discharge port 13, classifying and collecting the parts for use in the equipment.
