AI Technical Summary
Technical Problem
In the existing technology, it is difficult to ensure a large measurement range while occupying little space, and the measurement accuracy is insufficient.
Method used
The battery cell is held by a gripper assembly, and the relative movement of the gripper blocks is measured by using a grating ruler and a reading head. The diameter of the battery cell is calculated by the high-precision measurement of the grating ruler. Combined with the design of the guide assembly and limit block, the flexibility and accuracy of the measurement are improved.
Benefits of technology
It enables real-time measurement of battery cell diameter, improves measurement accuracy and applicability, reduces measurement errors, and features a simple and compact structure that saves space.

Abstract
本发明公开一种电芯直径测量装置，包括第一驱动件、夹爪组件、测量夹持件和测量组件。利用两个夹爪夹持电芯，能够对电芯进行有效固定，进一步通过复位件拉动两个测量夹块相对靠近并抵接在电芯的外周，两个测量夹块带动光栅尺和读数头相对移动，通过光栅尺和读数头相互配合，获取两个测量夹块之间的相对移动量，从而能够计算出电芯直径。这样，夹爪之间的距离不仅可以灵活调整，以便于适应多种尺寸的电芯，提高电芯直径测量装置的适用性。由于光栅尺具有较高的测量精度，采用光栅尺测量还能够避免使用相机拍摄的方法测量电芯直径，能够节省相机安装所占用的空间，在保证测量精度的前提下，使得电芯直径测量装置的结构更简单紧凑。
