Problems solved by technology
[0003] Generally, optical detection mechanisms such as CCD are used to detect whether the outer diameter of the cell meets the requirements. Since the cell is a three-dimensional structure, and it is necessary to ensure that the diameter of each section on it is within the rated size, the pixels of the image captured by the CCD should be high. , and the data analysis capability of the controller is high, which will increase the production cost of the detection equipment

Embodiment Construction
[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0030] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention discloses a battery cell boundary dimension detection device which comprises a bearing frame, a jig, an opening and closing driving assembly and a jacking assembly. The jig comprises a left sliding table and a right sliding table which are arranged on the bearing frame, a plurality of left arc-shaped grooves are formed in the left sliding table, a plurality of right arc-shaped grooves are formed in the right sliding table, and the left arc-shaped grooves and the right arc-shaped grooves jointly define go gauge holes; the opening and closing driving assembly is used for driving the left sliding table and the right sliding table to get close to or away from each other; the jacking assembly comprises a lifting driver and a plurality of elastic ejector rods, the elastic ejector rods are correspondingly contained in the go gauge holes, and the lifting driver is used for driving the elastic ejector rods to ascend or descend. Optical scanning is replaced by a mechanical mechanism to detect the outer diameter of the cell, and the research and development cost of equipment is reduced. After the left sliding table and the right sliding table are close to each other, the battery cell extending out of the go gauge hole under the thrust action of the elastic ejector rod is a qualified product, a plurality of battery cells can be detected at the same time, the detection efficiency is improved, the misjudgment probability is low, the test result is accurate, and defective products can be rapidly eliminated.
Description
technical field [0001] The invention relates to the technical field of battery production, in particular to a battery external dimension detection device. Background technique [0002] During the process of putting the battery into the shell, it is necessary to ensure that the size of the obtained battery core matches the caliber of the steel shell. In order to avoid scratching the battery when entering the shell, it is necessary to test the outer diameter of the battery before putting the battery into the shell to avoid damage during battery use. Potential safety hazards occur, and the production quality of batteries is improved. [0003] Generally, optical detection mechanisms such as CCD are used to detect whether the outer diameter of the cell meets the requirements. Since the cell is a three-dimensional structure, and it is necessary to ensure that the diameter of each section on it is within the rated size, the pixels of the image captured by the CCD should be high. ,...
