Background technology
Rectangular cell is a kind of widely used battery, and because qualified rectangular cell has various standard specifications, finished product rectangular cell various aspects must meet these standard specifications.Therefore, rectangular cell, before dispatching from the factory, must be measured apparent sizes such as thickness.Particularly the manufacture craft of lithium ion rectangular cell requires will carry out cell thickness mensuration after decompression envelope bolt finishes.
In the prior art, apparatus and method that the apparent sizes such as thickness of various square shaped batteries measure etc. have been there are.
CN201177492Y discloses a kind of device of completed battery product appearance dimension checking, it checks district, width dimensions check district and gauge check district to form by length dimension, wherein, length dimension check district is comprised of length adjustment block and length and width benchmark block, width dimensions check district is comprised of width adjusting block and length and width benchmark block, and gauge measurement zone regulates block and thickness benchmark block to form by thickness; Described length adjustment block, length and width benchmark block, width adjusting block, thickness regulate block and thickness reference block to be fixed on successively on base plate; Each regulates block medial surface lower end that groove is set, and each regulates the width on block groove top to be less than the width of groove bottom.
CN2814435Y discloses a kind of rectangular cell measured material, comprises base, is arranged at the block on base, the regulating device that is arranged at block one end on base and measuring sonde.Wherein, block has the bearing surface of a butt battery side; Regulating device comprises the Height Adjustable slide block with respect to base; Measuring sonde is installed on slide block and it is parallel to the projection of block bearing surface and goes out and be positioned at the outside of bearing surface from the side by block.Described regulating device also comprises adjustment seat and adjusting screw(rod), and slide block is to be embedded in adjustment seat up and downly, adjusting screw(rod) be arranged on adjustment seat and slide block and with slide block threaded engagement.On base, block bearing surface, be equipped with backing plate and prevent battery surface scratch.
But, adopt the device of above-mentioned prior art, can not carry out efficiently by automated manner, and cannot avoid battery surface to scrape rub completely.
In the process of measuring at the thickness of square shaped battery, sometimes cannot realize exactly the action that is close to and departs from benchmark head, upper thereby battery surface does not come to benchmark head (reference point) sometimes, can cause like this mistake of the thickness of battery is surveyed.And, when coming to battery on benchmark head and taking out, easily with benchmark head generation scratching, thereby on battery surface, produce cut from fixture after detection completes, cause battery surface bad order.
