Embodiment 1

[0068] Before the top-side sealing and packaging process of the soft-pack lithium battery, it is necessary to ensure that the quality of the core of the soft-pack lithium battery is qualified, to prevent the cores with tab margins and tab widths from entering the next step, and to ensure that the core is accurate. Inserting into the shell prevents damage to the lugs during the process of inserting the core into the shell, which affects the production quality.

[0069] In view of the above problems, the embodiment of the present application provides a method for detecting and entering the case of the soft-pack battery core, which can determine the quality of the core packaged into the case, and can avoid inaccurate grasping and entering the case when grabbing the core into the case. The resulting damage to the tabs improves the production quality of the pouch battery.

[0070] The technical solutions of the embodiments of the present application are described in detail below wi...

Embodiment 2

[0088] In order to facilitate understanding, an example of the method for detecting and inserting the core of the pouch battery into the case is provided below for illustration. The core is imaged by measuring the core, so that there is a significant difference in the gray value between the core to be tested and the background in the obtained core detection image. When the core to be tested is judged to be a good product, it will be determined according to the core detection image The coordinates of the center point of the core body of good product.

[0089] see figure 2 , the second embodiment of the method for detecting and inserting the core of the soft pack battery shown in the embodiment of the present application includes:

[0090] 201. Obtain the focus point of the industrial camera and establish a camera coordinate system according to the focus point;

[0091] Fix the industrial camera at a specified position, and obtain the focus point position of the industrial ca...

Embodiment 3

[0108] For ease of understanding, the following provides an example of a method for detecting and inserting soft-pack battery cores into the casing. In practical applications, the affine between the camera coordinate system and the base coordinate system of the manipulator will be determined through position calibration processing. Transform the matrix and the center of rotation to establish the spatial transformation relationship between the industrial camera and the manipulator, control the movement offset of the manipulator, and achieve the purpose of precise grasping and precise shell insertion.

[0109] see image 3 , the third embodiment of the method for detecting and inserting the pouch battery core into the shell shown in the embodiment of the present application includes:

[0110] 301. Perform position calibration processing on the industrial camera and the manipulator;

[0111] Control the manipulator to grab the position calibration plate to move to K preset posit...

Abstract

This application relates to a method for detecting and inserting a core of a pouch battery. The method includes: acquiring a winding core detection image, the winding core detection image includes a winding core to be tested; the winding core to be tested includes tabs and a main body of the winding core; determining the tab margin and the tab of the winding core to be tested according to the winding core detection image Width; judge the quality of the core to be tested according to the tab margin and the width of the tab; if the core to be tested is a good product core, and the good product core includes the good product core body, determine the quality of the good product core body according to the core detection image Center point coordinates; according to the center point coordinates, the manipulator is guided to grab good-quality roll cores and put them into the shell. The solution provided by this application can determine the quality of the winding core packaged into the case, and can avoid damage to the tabs caused by inaccurate grasping and insertion of the winding core into the case, and improve the production quality of the pouch battery.

Description

technical field [0001] The present application relates to the technical field of pouch battery packaging, and in particular to a method for detecting and inserting a core of a pouch battery. Background technique [0002] With the rapid development of the manufacturing industry, the previous low-efficiency and highly subjective manual repetitive inspection work is gradually being replaced by automated inspection, and standardized production has been greatly improved. Among them, before the top-side sealing and packaging process of the soft-packed lithium battery, it is necessary to ensure that the quality of the core of the soft-packed lithium battery is qualified, to prevent the cores with tab margins and tab widths that do not meet the standard from entering the next process, and to ensure that the roll The core is accurately inserted into the shell to prevent damage to the tabs during the process of winding the core into the shell, which will affect the production quality....
