Embodiment 1

[0028] A batch of coated negative pole pieces is measured with the lever type dynamic thickness gauge of the present invention.

[0029] figure 2 It is a schematic diagram of the battery pole piece coating and thickness detection process of the present invention.

[0030] Copper sheet is used as the negative electrode material, and the thickness is measured after coating the slurry on the coating machine. The thickness requirements are: 110 μm ± 5 μm on one side and 210 μm ± 5 μm on both sides.

[0031] After the double-sided coating and drying process is completed, the pole piece continuously moves through the bearings 19 and 20 of the thickness gauge, and the coating thickness of several points is manually measured with a dial gauge within a certain length, and the digital display is observed at the same time. The reading shown on the meter, if the reading of the digital display dial gauge is inconsistent with the data measured manually, the position of the balance weight ...

Embodiment 2

[0036] Use the lever type dynamic thickness gauge of the present invention to measure the thickness of the double-sided coated positive electrode sheet.

[0037] The positive pole piece is aluminum foil, the coating slurry used is different from that in Example 1, and the hardness of the coated pole piece is smaller than that of the coated pole piece in Example 1. Coating thickness requirements are: 104μm±5μm on one side and 192μm±5μm on both sides.

[0038] The operation sequence is basically the same as in Embodiment 1. The pole piece continuously moves through the bearings 19 and 20 of the thickness gauge, and manually measures the coating thickness of several points with a dial gauge within a certain length, and at the same time observes the readings displayed by the digital display dial gauge. The reading of table is inconsistent with the data of manual measurement, then need to adjust the position of balance weight 4, at this moment, the hardness of the post-coating pol...

Embodiment 3

[0043] Use the lever type dynamic thickness gauge of the present invention to measure the thickness of the negative electrode after the rollers are aligned. The thickness is required to be 140 μm-145 μm, and the operation steps and sequence are the same as those in Examples 1 and 2.

Abstract

A lever type dynamic thickness measuring meter for thickness of battery electrode piece, which contains base, support, lever, digital display dial gauge and balance block, one end of lever connected with the upper bearing, when the object to be measured passes the upper and lower bearings, the upper bearing is lifted, the height change transmitted to another end of lever by said lever, this end contacted with rod of digital display dial gauge and generating a numerical reading which is the height of the object to be measured, the balance block in upper bearing and lever can be adjusted according to hardness of measured object. Said invention raises measurement precision and avoids the error duo to manual measurement and the difference of hardness of objects.

Description

Technical field: [0001] The invention relates to a lever-type dynamic thickness gauge, in particular to a thickness gauge for measuring the thickness of battery pole pieces during the coating process or after roller alignment in the manufacturing process of batteries such as lithium batteries. Background technique: [0002] In the manufacturing process of batteries such as lithium batteries, especially in the coating process, it is necessary to control the thickness of the pole piece after coating or rolling in real time. When the thickness of the coated pole piece exceeds the range required by the process, the coating should be adjusted in time Machine or roller device to control the coating thickness within the range of process requirements. [0003] figure 1 Shown is the usual measurement and control method for the coating thickness of the pole piece. In the traditional measurement of the coating thickness of the battery pole piece, the inspectors regularly measure and r...
