Embodiment Construction

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0059] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time. When an element is referred to as being "disposed on" another element, it can be directly disposed on the other element or an intervening element may also exist.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one...

Abstract

The invention provides a prediction model training method. The training method comprises the following steps: acquiring historical operation data of laser welding; splitting the historical operation data to form a training set and a verification set; training a preset model according to the training set to obtain a first model; inputting the verification set to the first model, and determining evaluation parameters; determining that the evaluation parameters meet preset requirements; and determining a prediction model based on the evaluation parameter meeting a preset requirement. The invention further provides an electronic device used for executing the training method. The invention also provides a laser diagnosis device and method. The laser diagnosis method comprises the following steps: inputting feature data to the prediction model to obtain a predicted temperature; inputting the predicted temperature to the second model to form an early warning interval; and determining the health state of the laser based on the temperature and the early warning interval. When the temperature of the laser is input, the health state of the laser and whether early warning is carried out or not can be determined according to the early warning interval, and defective products caused by the fact that early warning cannot be carried out in advance are avoided.

Description

technical field [0001] The present application relates to the field of welding technology, in particular to a training method for a predictive model, an electronic device, a laser diagnostic device and a method. Background technique [0002] The laser is the key component of the laser welding machine. Whether the laser operating data is normal determines the processing quality of the workpiece. Therefore, it is usually necessary to monitor the processing parameters of the laser during production and processing. When the processing parameters exceed the preset range value, the maintenance personnel will be notified. repair. [0003] At present, the setting of the early warning range is based on the work experience of the operator. Since the work experience of different operators is inconsistent, it is difficult to form a unified range standard. Moreover, the existing laser welding machines cannot give early warning or the warning effect is poor. When the processing parameter...
