Description

Technical Field

[0001] This application relates to the field of aluminum ingot inspection, and in particular to an aluminum ingot surface quality inspection device. Background Technology

[0002] Aluminum ingots are metal blocks produced by electrolytic alumina production or by smelting recycled aluminum. They represent the primary processed form of aluminum and typically have high purity, containing up to 99.7% aluminum. Internationally, they are known as standard aluminum, and domestically as A00 aluminum. Aluminum ingots are lightweight, corrosion-resistant, and easy to process, making them the second most abundant metal material after steel. Surface quality inspection is frequently required for aluminum ingots. This inspection involves a systematic examination of the ingot's appearance for defects through visual inspection and instrumental measurement to ensure compliance with industry standards and provide qualified raw materials for subsequent processing. Inspections must adhere to relevant standards, strictly controlling defect types, dimensions, and cleanliness. Non-conforming products are prohibited from entering the warehouse, and data must be recorded and archived. This inspection is a crucial step in aluminum production, directly impacting the yield and product quality of subsequent processes. To inspect the surface quality of aluminum ingots, the transfer frame is stabilized, and the aluminum ingot is placed on top of it. The transfer frame controls the movement of the ingot. A support frame is fixedly installed on the top of the transfer frame, and a detection camera is fixedly connected to its surface. The camera captures images of the aluminum ingot surface, and deep learning algorithms are used to achieve real-time online monitoring of surface defects.

[0003] Regarding the aforementioned technologies, the inventors believe that because the surface of aluminum ingots is relatively smooth, it is easy for the surface of aluminum ingots to reflect light when the external light is concentrated. This reflection affects the camera of the testing agency when taking pictures, resulting in poor picture quality and affecting the accuracy of quality testing of aluminum ingot surface.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0016] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0017] This application discloses an aluminum ingot surface quality inspection device, referring to... Figure 1 - Figure 2The system includes a transmission frame 1. During inspection, after the transmission frame 1 is installed stably, the aluminum ingot is placed on the upper part of the transmission frame 1. The movement of the aluminum ingot is controlled by the transmission frame 1. A support frame 2 is fixedly installed on the top of the transmission frame 1. A detection camera 3 is fixedly connected to the surface of the support frame 2. The detection camera 3 takes pictures of the surface of the aluminum ingot. Combined with deep learning algorithms, real-time online monitoring of surface defects is achieved. A top plate 4 is installed on the surface of the support frame 2. A polyester shielding cloth 5 is fixedly installed at the bottom of the top plate 4. Several lights 6 are fixedly installed at the bottom of the detection camera 3. By utilizing the light-blocking properties of the polyester material of the shielding cloth 5, the light source around the detection camera 3 is blocked, and the light source is provided by the lights 6, thereby ensuring the detection effect of the aluminum ingot surface quality and effectively preventing external light sources from affecting the shooting effect of the detection camera 3.

[0018] Reference Figure 2 A connecting frame 8 is fixedly installed at the bottom of the shielding cloth 5. A slider 9 is fixedly connected to the surface of the connecting frame 8. The surface of the slider 9 is slidably installed against the inner wall of the support frame 2. By sliding the slider 9 against the inner wall of the support frame 2, the height of the connecting frame 8 can be easily adjusted, thereby controlling the length of the shielding cloth 5. This facilitates the detection of aluminum ingots of different sizes. An electric push rod 10 is fixedly installed at the top of the slider 9. The top of the electric push rod 10 is fixedly connected to the inner wall of the support frame 2. By adjusting its own length, the electric push rod 10 controls the slider 9 to slide within the support frame 2, thereby automatically controlling the length of the shielding cloth 5. This makes it more convenient to use. A polycarbonate lampshade 7 is fixedly connected to the bottom of the detection camera 3. By utilizing the high light transmittance and low light loss characteristics of the polycarbonate material of the lampshade 7, the light from the lighting lamp 6 is uniform and soft, close to the effect of natural light, thereby preventing the lighting lamp 6 from causing reflections on the aluminum ingots.

[0019] Reference Figure 3 - Figure 4 A rubber auxiliary piece 11 is installed at the bottom of the connecting frame 8. The auxiliary piece 11 blocks the connection between the connecting frame 8 and the transmission frame 1 when they come into contact, preventing collisions between them. Two adjusting frames 12 are fixedly connected to the surface of the slider 9. The surface of the adjusting frame 12 slides in the groove 13 inside the support frame 2. The adjusting frame 12 and the groove 13 improve the stability of the connection between the slider 9 and the support frame 2, preventing angular deviation between the slider 9 and the connecting frame 8. Two rollers 14 are rotatably connected inside the adjusting frame 12. The surface of the rollers 14 slides in the inner wall of the groove 13. The rollers reduce the friction between the adjusting frame 12 and the groove 13, making it easier for the connecting frame 8 to move.

[0020] The implementation principle of the aluminum ingot surface quality inspection device in this application embodiment is as follows: A top plate 4 is installed on the surface of a support frame 2. A polyester shielding cloth 5 is fixedly installed at the bottom of the top plate 4. Several lighting lamps 6 are fixedly installed at the bottom of the inspection camera 3. The polyester shielding cloth 5 has a light-blocking effect, thus blocking the light source around the inspection camera 3. The lighting lamps 6 provide the light source, effectively preventing external light sources from affecting the imaging effect of the inspection camera 3. A connecting frame 8 is fixedly installed at the bottom of the shielding cloth 5. A slider 9 is fixedly connected to the surface of the connecting frame 8. The surface of the slider 9 is slidably installed against the inner wall of the support frame 2, allowing the slider 9 to slide against the inner wall of the support frame 2, thereby... The height of the connecting frame 8 can be easily adjusted to control the length of the shielding cloth 5, facilitating the detection of aluminum ingots of different sizes. An electric push rod 10 is fixedly installed on the top of the slider 9, and the top of the electric push rod 10 is fixedly connected to the inner wall of the support frame 2. This allows the slider 9 to slide within the support frame 2 after adjusting its own length, thereby automatically controlling the length of the shielding cloth 5, making it more convenient to use. A polycarbonate lampshade 7 is fixedly connected to the bottom of the detection camera 3. By utilizing the high light transmittance and low light loss characteristics of the polycarbonate material of the lampshade 7, the light from the lighting lamp 6 is made uniform and soft, close to the effect of natural light, thus preventing the lighting lamp 6 from causing reflections on the aluminum ingots.

[0021] A rubber auxiliary piece 11 can also be installed at the bottom of the connecting frame 8 to shield the connecting frame 8 from contact with the transmission frame 1, preventing collisions between them. Two adjusting frames 12 are fixedly connected to the surface of the slider 9. The surface of the adjusting frame 12 is slidably installed with the slide groove 13 inside the support frame 2, which improves the stability of the connection between the slider 9 and the support frame 2 and prevents angular deviation between the slider 9 and the connecting frame 8. Two rollers 14 are rotatably connected inside the adjusting frame 12. The surface of the rollers 14 is slidably connected with the inner wall of the slide groove 13, which reduces the friction between the adjusting frame 12 and the slide groove 13, making it easier for the connecting frame 8 to move.
