Description

Technical Field

[0001] This utility model relates to the field of automatic optical inspection technology, specifically to a device for detecting the floating height of copper sheets in the middle frame of a foldable screen. Background Technology

[0002] In the manufacturing process of copper sheets for foldable screens in the mobile phone industry, the problem of copper sheet height defects is extremely common. Products with high copper sheet height defects will cause the final product to be scrapped if they flow into the next process. These defects are easy to miss when detected by manual inspection, and the work efficiency is low, the labor intensity is high and it is easy to cause visual fatigue. The internal structure of the product is complex and has many irregular shapes. It is necessary to inspect multiple copper sheet inspection points on both sides, which is difficult to do manually and is prone to inaccurate inspection data.

[0003] Currently, the main methods used in the industry to detect the floating height of the copper sheet in the foldable screen mid-frame are: using a coordinate measuring machine to detect the floating height of the copper sheet in the foldable screen mid-frame. This method is wasteful of manpower and resources and is inefficient. In addition, the floating height of the copper sheet in the foldable screen mid-frame needs to be detected on both sides and bound to a QR code. Manual detection is bound to miss some parts. Therefore, we propose a device for detecting the floating height of the copper sheet in the foldable screen mid-frame to solve the above problems. Utility Model Content

A computer host 12 is fixedly installed at the bottom inside the marble base 11. A frame fence 8 is fixedly connected to the four corners of the top of the marble base 11.

[0024] The folding screen frame of the product is placed on the loading platform 19 by the operator or another loading machine. The safety light curtain confirms that the operator's arm is away from the mechanical movement area. The clamping and positioning cylinder 14 positions the product. The Y-motion component 16 moves to the scanning position, and the barcode scanner 13 scans and binds the product's QR code. After scanning, the Y-motion component 16 moves to the copper sheet floating detection position. The X-motion component 17, carrying the 3D camera 18, scans the copper sheet on side A in the X direction of the product at a constant speed. After completion, the Y-motion component 16 moves forward a fixed distance, while the X-motion component 17, carrying the 3D camera 18, returns to its initial position. Once the product is in position, the X-motion component 17, carrying the 3D camera 18, continues scanning at a constant speed. The product's copper sheet along the B side in the X direction is scanned. After completion, the DD rotary motor 15 rotates the product horizontally by 90 degrees. At the same time, the X moving component 17, carrying the 3D camera 18, returns to its initial position. After the product is in place, the X moving component 17, carrying the 3D camera 18, continues to scan the copper sheet along the A side in the Y direction at a constant speed. After all surfaces are photographed, the obtained data is transmitted to the computer host 12 in real time. The software AI algorithm analyzes and determines whether the floating height of the copper sheet in the folding screen's mid-frame is OK or NG. The judgment indicator 10 indicates whether the product is NG or OK. The operator or the unloading machine sorts the OK and NG products. This process is repeated to complete the floating height detection of the copper sheet in the folding screen's mid-frame. Example

Specifically, three-color lights 5 are fixedly installed on both sides of the top of the frame fence 8. The three-color lights 5 provide light indication of the working status.

[0027] Specifically, several shock-absorbing feet 1 are fixedly installed at the bottom of the marble base 11, and a dual start button 9 and a judgment indicator light 10 are fixedly installed at one end of the marble base 11. After all surfaces are photographed, the obtained data is transmitted to the computer host 12 in real time. The software AI algorithm analyzes and judges whether the floating height of the copper sheet in the folding screen frame is OK or NG. The judgment indicator light 10 indicates whether the product is NG or OK. The operator or the unloading machine unloads and sorts the OK and NG products.

[0028] Specifically, the bottom of the marble base 11 is equipped with a power interface 6 and an air source interface 7, which provide the necessary energy for the testing work.

[0030] Reference Figure 1-4This is the third embodiment of the present invention. Based on the previous two embodiments, during the testing process, the folding screen frame of the product is placed on the loading platform 19 by an operator or other loading machine. The safety light curtain confirms that the operator's arm is away from the mechanical movement area. The clamping and positioning cylinder 14 positions the product. The Y-motion component 16 moves to the scanning position, and the barcode scanner 13 scans and binds the product's QR code. After scanning, the Y-motion component 16 moves to the copper sheet floating detection position. The X-motion component 17, carrying the 3D camera 18, scans the copper sheet on side A in the X direction of the product at a uniform speed. After completion, the Y-motion component 16 moves forward a fixed distance, while the X-motion component 17, carrying the 3D camera 18, returns to its initial position. After the product is in place, the X-motion component... Component 17, carrying 3D camera 18, continues to scan the copper sheet on side B in the X direction of the product at a constant speed. After completion, DD rotary motor 15 rotates the product horizontally by 90 degrees. At the same time, X-moving component 17, carrying 3D camera 18, returns to its initial position. After the product is in place, X-moving component 17, carrying 3D camera 18, continues to scan the copper sheet on side A in the Y direction of the product at a constant speed. After all sides are photographed, the obtained data is transmitted to the computer host 12 in real time. The software AI algorithm analyzes and determines whether the floating height of the copper sheet in the folding screen's middle frame is OK or NG. The judgment indicator 10 indicates whether the product is NG or OK. The operator or unloading machine sorts the OK and NG products. This process is repeated to complete the floating height detection of the copper sheet in the folding screen's middle frame.
