Problems solved by technology

[0003] However, the current NDC scanner is making product quality judgments to determine the correct parameters. In the past, the corresponding parameters of the qualified pole pieces were set to the correct parameters in a destructive way, which not only wastes qualified products, but also has certain limitations in parameter setting. deviation

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Such as Figure 1-4 As shown, the sample sampling device of the NDC measurement system of the present invention includes a sample holder 1 fixedly connected with the NDC measurement system such as the NDC8000 scanner and a sample holder 2 for carrying samples, and the sample holder includes a U-shaped The main frame 11 is horizontally and fixedly connected to the sample support plate 12 below the opening end of the U-shaped main frame. A through hole 13 matching the sample holder is provided at the center of the sample support plate, and a through hole 13 is provided at the bottom of the through hole. The inner flange is used to support and position the sample holder, that is,...

Abstract

The invention discloses a sample sampling device of an NDC measuring system, which includes a sampling rack and a sample fixture, wherein the sampling rack includes a U-shaped main frame fixedly connected with an NDC scanner, and a sample support plate horizontally and fixedly connected under the opening end of the U-shaped main frame; a through hole matched with the sample fixture is arranged at the center of the sample support plate; an inner flange is arranged at the bottom of the through hole to support and position the sample fixture; the sample fixture includes a lower ring body and an upper ring body; the upper ring body and the lower ring body clamp a sample therebetween and are fixedly connected through uniformly distributed screws. According to the sample sampling device provided by the invention, a qualified pole piece is placed on the sampling rack, and the qualified pole piece can be simulated, then the produced pole piece can be compared with the qualified pole piece (sample), so that whether the produced pole piece is qualified or not can be directly verified, as a result, destructive measurement on pole pieces and waste of quailed products are avoided.

Description

technical field [0001] The invention relates to the technical field of battery preparation, in particular to a sample sampling device of an NDC measurement system. Background technique [0002] Lithium-ion batteries are widely used in mobile communication devices and portable electronic devices, and the quality control of the core pole pieces is particularly important. In the preparation process of the pole piece, the coating amount (area density) of the coating process is an extremely important parameter of the pole piece. The NDC measurement system mainly includes the NDC scanner, which is a detection instrument for monitoring the surface density of the product. It passes The β-rays emitted by the upper probe pass through the product to be tested, and the lower probe receives the high-energy particles of the β-rays that pass through. The greater the quality of the product, the more particles are absorbed, and the smaller the electrical signal output of the detection device...
