Cylindrical battery testing platform

Abstract

A cylindrical battery testing platform comprises a linear reciprocating device, a rotating platform and testing benches. The linear reciprocating device is connected with a first servo motor. The testing benches are connected with the movably part of the linear reciprocating device. The testing benches are arranged at two sides of the rotating platform. The rotating platform is provided with rotating shafts which are used for supporting and rotating a battery. The rotating shafts are parallelly arranged in the motion direction of the linear reciprocating device. A to-be-tested area is formed between adjacent rotating shafts. The testing benches are provided with laser length measuring instruments. An included angle between laser transmitting direction of each laser length measuring instrument and the rotation direction of the rotating shaft is 5-90 DEG. The linear reciprocating device realizes spiral laser scanning in a plane through arranging the to-be-tested area which performs rotation relative to the transmitting direction of the laser length measuring instrument and cooperating with linear reciprocation of the laser length measuring instrument relative to the to-be-tested area, thereby realizing online automatic testing.

Description

technical field [0001] The invention relates to the field of battery testing equipment, in particular to a cylindrical battery testing platform. Background technique [0002] At present, the cylinders are manually inspected on the production line for the total length of cylindrical batteries, the inspection of flatness greater than 0.1MM, the scanning of battery barcodes, the visual inspection of battery damage, and the visual inspection of poor plastic packaging of batteries. Production requires a large number of workers, manual or semi-automatic operation of testing equipment in the battery sorting process, these operations have low automation, high labor costs, low efficiency, low precision, poor consistency, and many human factors, making it difficult to meet product quality requirements. At the same time, visual inspection has been used in battery production lines, but most of them are assembly-line, using different cameras to detect the corresponding content, and 3D im...

AI Technical Summary

Problems solved by technology

[0002] At present, the cylinders are manually inspected on the production line for the total length of cylindrical batteries, the detection of flatness greater than 0.1MM, battery barcode scanning, visual inspection of battery damage, and visual inspection of poor battery plastic packaging. This has led to the failure of most batteries. Production requires a large number of workers, manual or semi-automatic operation of testing equipment in the battery sorting process, these operations are low in automation, high in labor costs, low in efficiency, low in accuracy, poor in consistency, and many human factors, making it difficult to meet product quality requirements

At the same time, visual inspection has been used in battery production lines, but most of them are assembly-line, using different cameras to detect the corresponding content, and 3D imaging technology is used for bumps and bumps. Although it solves the problems of efficiency and quality, there are problems of misjudgment and high cost, and most companies are discouraged.

At present, the automatic detection is a single-station detection, the equipment covers an increased area, and the output per unit area is uneconomical
