[0050] Embodiment 2:

[0051] like Figure 5As shown, the screen laminating and hot pressing automatic splicing machine, the controller includes an equipment control module, an intelligent adjustment module, a workpiece positioning module and a workpiece detection module.

[0052] When the above modules are transmitting signals, the device control module receives and issues signals, and the controller actually controls each device.

[0053] The equipment control module is used to control the equipment during the operation of the device, and transmit the relevant data information of the screen of the object to be tested to the intelligent adjustment module, and record the operating data information of the device during operation.

Prepare a large number of labeled normal screen images and damaged screen images as training data to obtain a training model. Use the pre-training images to train the training model so that it can accurately identify damaged screen images. Input the image to be detected into the trained network, and the network will output the prediction result of whether the image is damaged.

[0063] S2: The transmitted screen is imaged through a camera collector, and the image is preprocessed and feature extracted. The processed image is sent to the training model for comparison, and the features of the image to be detected are matched with the features of the damaged template.

[0064] S3: If the model training result is a similar image, it means that the screen has defects and is an unqualified product. An unqualified signal is generated and transmitted to the device control module.

[0065] After receiving the unqualified signal, the controller of the equipment control module will perform numerical control translation 27 to control it so that it does not push the screen and discharges it to the inside of the discharge mechanism.

[0066] The size of the interval and threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technical personnel in this field for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value.

Prepare a large number of labeled normal screen images and damaged screen images as training data to obtain a training model. Use the pre-training images to train the training model so that it can accurately identify damaged screen images. Input the image to be detected into the trained network, and the network will output the prediction result of whether the image is damaged. S2: The transmitted screen is imaged through a camera collector, and the image is preprocessed and feature extracted. The processed image is sent to the training model for comparison, and the features of the image to be detected are matched with the features of the damaged template. S3: If the model training result is a similar image, it means that the screen has defects and is an unqualified product. An unqualified signal is generated and transmitted to the device control module.
