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

The invention relates to a method for detecting a roll core of a soft package battery to enter a shell. The method comprises the following steps: acquiring a roll core detection image, wherein the roll core detection image comprises a to-be-detected roll core, wherein the to-be-tested roll core comprises a tab and a roll core main body; determining the tab edge distance and the tab width of the to-be-detected roll core according to the roll core detection image; performing quality judgment on the to-be-detected roll core according to the tab edge distance and the tab width; if the to-be-detected roll core is a non-defective roll core and the non-defective roll core comprises a non-defective roll core main body, determining a center point coordinate of the non-defective roll core main body according to the roll core detection image; and guiding the manipulator to grab the good roll core into the shell according to the center point coordinate. According to the scheme provided by the invention, the quality of the roll core packaged into the shell can be determined, the condition of tab damage caused by inaccurate grabbing into the shell can be avoided when the roll core is grabbed into the shell, and the production quality of the soft package battery is improved.

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....
