Pole piece multi-position stripping sampling device and method

Abstract

The invention discloses a pole piece multi-position stripping sampling device. The pole piece multi-position stripping sampling device comprises a cabinet, a motor, a rack, an upper rolling cutter, a lower rolling cutter, a long shaft, a belt and a gear component, the motor is arranged in the cabinet, the rack is mounted on the cabinet, the upper rolling cutter, the lower rolling cutter and the long shaft are sequentially mounted on the rack from top to bottom, the belt sleeves the motor and the long shaft, the upper rolling cutter, the lower rolling cutter and the long shaft are in mutually meshed connection through the gear component, and an upper blade and a lower blade which correspond to each other are arranged on the upper rolling cutter and the lower rolling cutter respectively. The invention further discloses a sampling method of the device. The pole piece multi-position stripping sampling device and method has the advantages that the sampling device and method is convenient and quick in sampling operation, accurate in sampling size, suitable for large-scale sampling, applicable to high-frequency test sampling in the production process and large in sampling area, sampling operation efficiency is improved, and the device can be operated by one person, so that production cost is lowered; measuring errors are small, so that sampling accuracy is guaranteed.

Description

technical field [0001] The invention relates to the field of sampling devices, in particular to a pole piece multi-port strip sampling device and a sampling method. Background technique [0002] In today's increasingly tense energy environment, energy tends to be diversified, efficient, and non-polluting. As a new industry, power energy and power batteries have become new highlights in the automotive industry. [0003] The key to the main performance indicators of power batteries "high-rate discharge" and "high-temperature cycle" lies in how to control the surface density of the pole piece, and the main inspection method for controlling the surface density of the pole piece in the industry is to punch samples or use a steel ruler to measure the size before Cut the sample with a utility knife to measure the pole piece weight per unit area. The above two sampling methods have their own advantages and disadvantages. The manual punch is easy to operate, but the sampling area is...

Problems solved by technology

The above two sampling methods have their own advantages and disadvantages. The manual punch is easy to operate, but the sampling area is small and the measurement error is large; the utility knife cutting sampling area is large and the measurement error is small, but it is only suitable for small batch sampling in the laboratory Applied to multi-frequency inspection sampling in the production process
