Embodiment Construction

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other co...

Abstract

The invention discloses a method for detecting cold joints of leads of a lithium battery and a system for detecting soldering of the leads. A lead soldering detecting device is used for detecting theleads in real time, and a lead soldering database and a classifying model are established. The method includes the steps of data obtaining, basic data marking, generating of the classification model and outputting of a detection result, the leads to be detected are detected in real time, detection data is input into the classification model for comparison and analysis, whether or not the cold joints of the leads exist is judged, and the detection result is output. In the implementation of the method through the system, whether or not the cold joints occur on welding points of lead welding canbe rapidly detected, and therefore the automation and detection efficiency are improved.

Description

technical field [0001] The invention relates to the field of welding, in particular to a method for detecting false welding of tabs of a lithium battery and a detection system for tab welding. Background technique [0002] Tabs are a raw material for lithium-ion polymer battery products. For example, mobile phone batteries, bluetooth batteries, and notebook batteries used in our daily life all need to use tabs. The battery is divided into positive and negative poles, and the tabs are the metal conductors that lead the positive and negative poles out of the battery. In layman's terms, the ears of the positive and negative poles of the battery are the contact points when charging and discharging. This contact point is not the copper piece we see on the outside of the battery, but a connection inside the battery. The tabs are divided into three materials. The positive electrode of the battery is made of aluminum, the negative electrode is made of nickel, and the negative elec...
