[0002] The thickness of the polymer lithium-ion battery body is an important indicator to measure whether the battery is qualified. In the early days, most companies used the method of caliper sampling the thickness of the battery to measure the overall qualification rate. The ability to reflect data is poor, how to screen intuitively, quickly, and correctly, and at the same time ensure that the battery does not suffer from deformation, twisting, scratches, etc. during the screening process, has become the focus of the present invention.

The invention discloses a battery thickness measuring device comprising a bottom plate, a measuring plate, a cylinder and a digital display dial indicator. The measuring plate is disposed above the bottom plate and is arranged in parallel with the bottom plate. The upper end of the measuring plate is provided with an E-shaped plate, and the upper end of the E-shaped plate is provided with an L-shaped plate. The cylinder is disposed above the L-shaped plate, and the cylinder body is connected with the bottom plate. A piston rod is perpendicular to the measuring plate, and the lower end part of the piston rod is fixed at the joint of a second end part and a third end part. The digital display dial indicator is disposed above the E-shaped plate and the digital display dial indicator body is connected with the bottom plate. A measuring rod is perpendicular to the measuring plate, and the lower end part and the middle part of the measuring rod are connected. The cylinder drives the measuring rod of the digital display dial indicator to move. When the measuring plate and the bottom plate fit each other, the digital display dial indicator displays zero. When a battery is placed on the bottom plate and the measuring plate and the battery fit each other, the digital display dial indicator displays the thickness of the battery. No matter where the cylinder is disposed, the action force of the cylinder is enabled to be uniformly applied to the measuring plate through coordination between the E-shaped plate and the L-shaped plate so as to prevent the measuring plate from skew to affect the accuracy.
Description
technical field [0001] The invention relates to a battery thickness measuring device. Background technique [0002] The thickness of the polymer lithium-ion battery body is an important indicator to measure whether the battery is qualified. In the early days, most companies used the method of caliper sampling the thickness of the battery to measure the overall qualification rate. The ability to reflect data is poor, how to screen intuitively, quickly, and correctly, and at the same time ensure that the battery does not suffer from deformation, twisting, scratches and other damage during the screening process has become the focus of the present invention. Contents of the invention [0003] The problem to be solved by the present invention is to provide a battery thickness measuring device, which can quickly measure the thickness of the battery with high measurement accuracy, simple structure and convenient operation. [0004] In order to solve the above technical problems,...
