Description

Battery Thickness Measuring Instrument

technical field

The utility model relates to the technical field of measuring tools, in particular to a battery thickness measuring instrument.

Background technique

The manufacturing process of lithium-ion batteries is complex, and the process requirements are high, especially the assembly and winding process, the product sampling frequency is high, and the product process monitoring is very important. The traditional way to detect the size of the battery is basically by manual measurement, generally using a steel ruler or a vernier caliper to measure. This original measurement method has low accuracy and is inconvenient to operate. In battery manufacturing, the thickness of the battery is most of the time a full inspection station. Battery thickness measurement is to take the highest point size of the entire surface of the battery. This original measurement method cannot accurately measure the true maximum degree of the battery.

In order to solve this problem, the Chinese patent "A Lithium Battery Dimension Measurement Fixture" (Application No.: 201220048465.0) discloses the measurement of battery length and thickness by two scales in the vertical direction and the horizontal direction. This method can only measure the local size of the battery, and it is difficult to accurately capture the highest point size. It is easy to cause misjudgment, and the measurement efficiency is low.

detailed description

The specific implementation of the battery thickness measuring instrument of the present invention will be described in detail below.

Referring to accompanying drawings 1 and 2, the battery thickness measuring instrument includes a base 1, a moving plate 2 and a linear slide 3, the linear slide 3 is vertically arranged above the side of the base 1, the moving plate 2 is parallel to the platform of the base 1, and moves The board 2 is installed on the slider 4 of the linear slide table 3 . The linear slide table 3 is two groups, and the sliding block 4 of the mobile plate 2 and the two groups of linear slide table 3 is fixedly installed. A dial indicator 6 is installed on the top of the linear slide table 3 through a mounting plate 5 , and the contacts of the dial indicator 6 are in corresponding contact with the measuring block 7 on the top of the moving plate 2 . A cylinder 8 is arranged on one side of the linear slide 3, the piston rod of the cylinder 8 is connected with the slider 4 of the linear slide 3, and the cylinder 8 drives the slider 4 to move up and down, thereby driving the moving plate 2 to move.

Referring to accompanying drawings 3 and 4, during measurement, the cylinder 8 drives the moving plate 2 to move downward until the moving plate 2 cooperates with the platform of the base 1, at this moment, adjust the value of the dial gauge 6 to be 0. Then drive the moving plate 2 up to an appropriate position through the cylinder 8, place the battery 9 on the platform of the base 1, and move the moving plate 2 down until the moving plate 2 is in contact with the upper surface of the battery, and read the value of the dial gauge 6 is the thickness value of the battery 9 .

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made. It should be regarded as the protection scope of the present utility model.
