Description

The sample sampler of surface density measuring system

Technical field

The present invention relates to battery preparation technology field, particularly relate to the sample sampler of a kind of surface density measuring system.

Background technology

Lithium ion battery is widely used in portable communication equipment and portable electric appts, and the control of the pole piece quality of production of its core seems particularly important. In the preparation process of pole piece, the coating amount (area density) of working procedure of coating is the very important parameter of pole piece, NDC measuring system mainly comprises NDC scanner, it is the detecting instrument of the area density for monitoring product, it passes product to be measured by the �� ray radiated of upper probe, lower probe accept through Beta-ray high energy particle, quality product is more big, absorbed particle more many, the electrical signal of means of detection exports more little, after being transformed by electrical signal output linearity, obtain the quality of the unit surface of product, i.e. area density.

But present NDC scanner judges to determine this correct parameter carrying out quality product, it is be correct parameter by the corresponding parameter setting of producing qualified pole piece in a destructive manner in the past, not only wasted qualified product, and parameter setting has certain deviation.

Summary of the invention

It is an object of the invention to for the technological deficiency existed in prior art, and the sample sampler of a kind of surface density measuring system is provided.

The technical scheme adopted for realizing the object of the present invention is:

The sample sampler of a kind of surface density measuring system, comprise sampling rack and sample clamp, described sampling rack comprises the U shape body frame being fixedly connected with NDC scanner, level is fixedly connected on the load plate of the sample below U shape body frame opening end, described sample load plate center arranges the through hole mated with described sample clamp, arranges interior flange with supporting and location sample clamp in described via bottoms; Described sample clamp comprises lower annulus body and upper annulus body, and sample clamping wherein and is fixedly connected with by the described body of annulus up and down by equally distributed screw.

Pressure ring it is formed with highlightedly inside described upper annulus body or lower annulus body.

Carry at described sample and plate is fixedly installed water level gauge.

Described sample load plate is fixedly connected with U shape body frame by the four of both sides thru-bolts.

Finger discrepancy picks and places sample clamp to facilitate to be formed with semicircle breach in described sample load plate accommodation groove side.

Described sample load plate adopts aluminum alloy materials to make.

Compared with prior art, the invention has the beneficial effects as follows:

The sample sampler of the present invention, simple and stable structure, it is to increase scanning accuracy, can adopt different samples to detect the product of different batches simultaneously, changes easy, easy to adjust. Qualified pole piece is placed on sampling rack and can simulate qualified pole piece, then the pole piece produced is contrasted mutually with qualified pole piece (sample), can directly verify that whether the pole piece of production is qualified, avoid the destructive measurement to pole piece, avoid the waste of qualified product.

Embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail. It is to be understood that specific embodiment described herein is only in order to explain the present invention, it is not intended to limit the present invention.

As Figure 1-4, the sample sampler of the surface density measuring system of the present invention comprises and described NDC measuring system, the sampling rack 1 being fixedly connected with such as NDC8000 scanner and the sample clamp 2 in order to carry sample, described sampling rack comprises U shape body frame 11, level is fixedly connected on the load plate 12 of the sample below U shape body frame opening end, described sample load plate center arranges the through hole 13 mated with described sample clamp, in described via bottoms, interior flange is set with supporting and location sample clamp, namely described sample clamp can by supporting and location on the support edge of via bottoms. meanwhile, finger discrepancy picks and places sample clamp to facilitate to be formed with semicircle breach 15 in described sample load plate accommodation groove side.

Described U shape body frame 11 comprises crossbeam and is vertically formed the support arm at two ends, crossbeam side, is also provided with stiffening web to improve support arm intensity between described support arm bottom and crossbeam. Wherein, it is fixedly connected with the body of NDC8000 in the middle part of the crossbeam of described U shape body frame, allowing, the probe of NDC passes in and out the opening of U shape body frame 11, wherein, described sample load plate 12 adopts aluminum alloy materials to make, its light and not easily modification, long-time use also can not lose level because of deadweight. Described sample load plate 12 is fixedly connected with by the arm end of the four of both sides thru-bolts 13 with U shape body frame, and each thru-bolt has two butterfly screws laying respectively at the upper and lower both sides of platform, and described screw plays adjustment plateau levels effect.

Further, for observing the horizontality of sample load plate, carry at described sample and plate is fixedly installed water level gauge 14, specifically, carry at described sample and plate arranges through hole, described water level gauge is embedded in through hole and is screwed.

Described sample clamp comprises lower annulus body 21 and upper annulus body 22, pressure ring 23 it is formed with highlightedly inside lower annulus body, the described body of annulus up and down is by sample clamping, can by sample clamping and positioning in sample clamp by pressure ring, then the countersunk head screw being evenly distributed with eight is fixed, can ensure that sample is in tight state, be conducive to the measurement of coating amount.

When detecting, first qualified pole piece is taken off, the qualified pole piece taken off is placed in the middle of upper lower clamp, fixing to clamp exceptionally straight sample with countersunk head screw, then being placed on by the sample clamp made on sample load plate, the height of adjustment sample load plate and level, adjust after well, locking screw, sampling rack just need not move substantially. NDC measuring system sets sampling spot, general position is at the sample center of sampling rack, click sampling, NDC probe is taken up in order of priority and is scanned product and sample, the comparative result of the coating amount (i.e. area density) of product and sample can be observed, it is possible to directly judge that whether qualified product is by the display screen of NDC scanner.

The above is only the preferred embodiment of the present invention; it should be appreciated that for those skilled in the art, under the premise without departing from the principles of the invention; can also making some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
