Embodiment 1

[0024] A scanning mechanism for a laser thickness gauge, comprising a mounting table 2, a C-shaped frame 8 is arranged on the mounting table 2, and the angle between the C-shaped frame 8 and the horizontal plane is within ±10° (this embodiment Take the C-shaped frame 8 as a horizontal setting for illustration, that is, the angle between the C-shaped frame 8 and the horizontal plane is 0°), and a group of laser sensors 9 for detecting thickness are provided on the C-shaped frame 8 .

[0025] A guide rail 7 is fixed on the installation table 2 , and a slide block 6 is arranged on the guide rail 7 , and the slide blocks 6 are all fixedly arranged on the C-shaped frame 8 . The mounting table 2 is provided with a servo motor 3, and the servo motor 3 is connected with a screw mandrel 14 through a coupling 4, and the screw mandrel 14 is provided with a lead screw nut 5, and the lead screw nut 5 is connected to the screw mandrel 14. The slide block 6 is connected and fixed to drive th...

Embodiment 2

[0028] The difference from the first embodiment above is that the center of gravity of the C-shaped frame 8 is on the left side frame 11 . The position of the center of gravity of the C-shaped frame 8 is set in a vertical plane passing through the axis of the guide rail 7 . Put the center of gravity on the left side frame 11, because the guide rail 7 is below the left side frame 11, the center of gravity falls in the vertical plane passing through the axis of the guide rail 7, and the left side frame 11 runs more smoothly, so that the left side frame of the C-shaped frame 8 11 and the mechanical vibration produced by the right frame 12 are smaller, which improves the measurement accuracy. If a double guide rail multi-slider structure is adopted, two guide rails are set under the left side frame 11 and the right side frame 12, and the parallelism of the two guide rails cannot be fully guaranteed. The sliders on the two guide rails are fixed on the C-shaped frame. Two sliders c...

Abstract

The invention relates to a scanning mechanism of a laser thickness gauge, which comprises a mounting table. A C-shaped frame is arranged on the mounting table. The C-shaped frame is arranged horizontally and provided with a set of laser sensors for detecting thickness. According to the invention, the thickness of a material is measured through the C-shaped frame scanning mechanism that is horizontally arranged. The direction of mechanical vibration generated by the horizontal C-shaped frame is perpendicular to the measurement directions of the two laser sensors, which greatly reduces the influence of the mechanical vibration on measurement accuracy. At the same time, the invention adopts a combination form of one guide rail and two sliders, which effectively prevents the two guide rails and the multiple sliders from mutual restraint and interference in movement, so the accuracy and stability of the measurement data of the thickness gauge are effectively achieved.

Description

technical field [0001] The invention belongs to the technical field of laser detection, and in particular relates to a laser thickness gauge for measuring the thickness of coated pole pieces of lithium batteries. Background technique [0002] With the continuous development of lithium battery production technology, the requirements for the uniformity and thickness accuracy of the coated pole pieces of lithium batteries are also getting higher and higher. [0003] The existing detection technology and tools cannot measure the thickness of the wet film pole piece after coating of lithium battery in real time. Usually, you can only go to the back of the oven with a length of tens of meters, disconnect the pole piece after drying, and then measure manually. The mold adjuster of the coater adjusts the corresponding position of the die head of the coater according to the measured thickness data in the width direction of the pole piece. Multiple repeated adjustments are required ...
