Embodiment 1

[0026] Please refer to figure 1 , the figure shows a schematic diagram of the steps of an online quality inspection and control method for an ultrasonic welding machine. This embodiment provides an online quality inspection and control method for an ultrasonic welding machine, including:

[0027] Step S1, select a batch of qualified power batteries as available samples, and it is not enough to judge the welding quality of the power battery to be tested by using only one ultrasonic welding data, there will be various deviations, so it is necessary to pass a set of Qualified power batteries that have been welded are used as samples. All samples must be able to pass the insertion force failure test and meet the national standards, so that the samples can be reliable and the first model obtained can meet the requirements.

[0028] Step S2, extract the detailed data of the ultrasonic welding process of the qualified power battery. The detailed data of the sample has been recorded i...

Embodiment 2

[0045] Please refer to figure 2 ,exist figure 2 shows an online quality inspection and control device for an ultrasonic welding machine, including:

[0046] The communication controller 101 is used to collect dynamic data and static data during the ultrasonic welding process of the power battery to be tested to obtain dynamic data and static data.

[0047] The storage controller 102 is connected with the communication controller 101 and used for storing the dynamic data and the static data.

[0048] The logic controller 103 is connected with the storage controller 102 and configured to process the dynamic data and the static data.

[0049] The detection controller 104 is connected with the logic controller 103 and used for judging whether the power battery to be tested is qualified according to the static data and the dynamic data.

[0050] The display controller 105 is connected with the detection controller 104 and is used for accurately displaying the determination res...

Abstract

The invention discloses an online quality detection control method and device for an ultrasonic welding machine. The method comprises the following steps: selecting a batch of qualified power batteries as available samples; extracting various detailed data of the sample in the ultrasonic welding process; carrying out data processing on detailed data of the sample, extracting static data characteristics of the power battery in the welding process, and establishing a first model; trial production is conducted, and dynamic data in the ultrasonic welding process are recorded in the production process; processing the dynamic data of trial production to obtain dynamic data characteristics; correcting the first model according to the dynamic data characteristics obtained by trial production to form a second model; according to the method and device for detecting the welding quality of the power batteries, the static data and the dynamic data of the ultrasonic welding process of the power batteries to be detected are collected and compared with the data characteristics of the second model, whether the power batteries are qualified or not is judged, and the welding quality of each power battery can be quickly, conveniently and accurately detected.

Description

technical field [0001] The invention relates to the technical field of quality monitoring of ultrasonic welding machines, in particular to an online quality detection and control method and device of ultrasonic welding machines. Background technique [0002] The working principle of the ultrasonic welding machine requires two parts to be combined. The upper one vibrates at a high frequency and the lower one is stationary. The frictional heat on the contact surface melts the plastic on the surface to combine. [0003] Compared with other traditional processes (such as gluing, electric ironing or screw fastening, etc.), ultrasonic welding machines have significant advantages such as high production efficiency, good welding quality, environmental protection and energy saving, so ultrasonic welding equipment is widely used in various fields . [0004] At present, under the background of vigorously promoting clean energy in the country, the development of automobile power batter...
