Module component assembly method and module component assembly device

Abstract

The present invention provides a module component assembly method and a module component assembly device. The module component assembly method includes: step a. acquiring the image of the battery module, and obtaining the deviation value of the linear characteristic slope on the battery module , and the deviation value of the feature point coordinates; Step b. The manipulator grabs the module part, and obtains the image of the captured module part, and obtains the deviation value of the linear characteristic slope on the module part, and the deviation of the feature point coordinates value; step c. according to the deviation value of the linear characteristic slope on the battery module and the deviation value of the characteristic point coordinates, and the deviation value of the linear characteristic slope and the deviation value of the characteristic point coordinates on the module parts, adjust the manipulator to grab The shape of the module parts eliminates each deviation value, and the module parts are installed on the battery module by the robot. The method for assembling the module components of the present invention eliminates various deviation values ​​by adjusting the shape of the module components grasped by the manipulator, thereby improving the assembly accuracy of the module components.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a method for assembling module components. At the same time, the invention also relates to a module component assembly device. Background technique [0002] In the process of assembling module components, manual installation and positioning methods are usually used for assembly work, which requires the operator to focus on the product for a long time, which will not only make the operator's eyes very tired, but also the operator's mood swings It will also affect the assembly effect. In addition, operators have some misunderstandings about positioning and defect standards, which is not conducive to improving product quality, and makes the overall assembly speed relatively slow, making it difficult to meet today's fast and automated production requirements. [0003] At present, the technology of machine vision has been introduced into industrial production. It can convert...

AI Technical Summary

Problems solved by technology

[0004] (1) Relying solely on mechanical positioning requires extremely high processing accuracy and stability of the equipment, and requires a strict daily inspection and maintenance system, which leads to an increase in the workload of personnel;

[0005] (2) During the design of the module production line, there is no tolerance for the injection molded parts of the installation busbar, so there are certain errors in parts from different manufacturers and different batches. Only using mechanical positioning will cause a large number of defective products or frequent alarms for equipment, thus affecting the entire system. Operation of the production line;

[0006] (3) The accuracy of the module logistics line is not high. There is a certain deviation in the position of each battery module at the station. The simple mechanical positioning design is difficult, and the logistics line needs to be transformed. Not only the input cost is high, but also the impact on production capacity larger;

[0007] (4) Once an abnormality occurs during the operation of the equipment, the equipment cannot be sensed in time and the alarm will be reminded. When the flow to the next station is discovered, multiple battery modules have been scrapped
