Description
Technical Field
The application relates to a battery pole piece surface density measurement device, in particular to a battery pole piece on-line surface density measurement instrument.
Background
The mass of the pole piece per unit area is called the areal density of the pole piece. The areal density of the pole pieces is the most important factor in determining the uniformity of the cell. Beta rays generated by decay of Kr85 (krypton 85) penetrate the battery pole pieces, and a part of the rays are absorbed by the pole pieces. The intensity of the rays penetrating through the pole piece is attenuated to a certain degree relative to the intensity of the incident rays. The decay ratio is in negative exponential relation with the areal density of the penetrated pole piece. The surface density of the pole piece can be calculated by measuring the ray intensity before and after the rays penetrate the pole piece through the special gas ionization chamber.
As shown in figure 1 of the drawings,
I 0 the radiation intensity before transmission can be understood as the radiation intensity without the blocking of the pole piece;
i is the intensity of the transmitted rays, which can be understood as the intensity of the rays when the rays pass through the pole piece;
both satisfy m=1/λ (㏑ (I 0 /I)) relationship;
wherein lambda is the absorption coefficient of the unit area of the pole piece;
m is the areal density; areal density is defined as the weight per unit area s of the pole piece. If the density ρ of the object is fixed, the areal density of the object is proportional to the thickness d: areal density = m/s = ρd. Since the lithium electrode coating production process cannot ensure constant density, the pole piece surface density cannot be calculated directly by measuring the thickness.
The prior art generally measures the intensity I of the radiation before transmission 0 When the radiation intensity is acquired at the position without the pole piece, the ionization chamber and the radiation emitter of the measuring instrument are required to move to the position without the pole piece, then the radiation intensity is acquired under the static condition, and a certain time is required for acquiring the radiation intensity each time, so that the measuring efficiency is low.

Compared with the prior art, the ionization chamber in the prior art is set to be 2 scintillation detectors, the ionization chamber in the prior art comprises the first scintillation detector 33 and the second scintillation detector 42, wherein the first scintillation detector 33 is arranged between the ray tube 32 and the first emitting hole 34 of the first box body 31, the second scintillation detector 42 is arranged in the second box body 41, when the ray emitting device 3 and the ray receiving device 4 move and measure on the battery pole piece 7, the first scintillation detector 33 acquires the ray intensity emitted by the ray tube 32 in real time while moving along with the ray emitting device 3, the ray intensity is the ray intensity before transmission, and the measurement accuracy is high because the second scintillation detector 42 is smaller than the volume of the prior ionization chamber, so that the second scintillation detector 42 can be arranged in the ray emitting device 3, and can acquire the ray intensity before transmission in real time; in addition, the first scintillation detector 33 acquires the ray intensity emitted by the ray tube 32 in real time while moving along with the ray emission device 3, and compared with the prior art, the radiation intensity before transmission is acquired without driving the ray emission device 3 to move outside the battery pole piece 7, so that the measurement efficiency is greatly improved.
Ionization chamber: the ionization chamber is a detector for measuring the ionizing radiation by utilizing the ionizing effect of the ionizing radiation, and is also called an ionization chamber, and mainly comprises a collector and a high-voltage electrode, wherein gas is arranged between the collector and the high-voltage electrode, and when rays in the environment penetrate through a shell of the high-voltage electrode and enter the high-voltage electrode, the ionization effect is generated with the gas. Because of the electric field effect between the high-voltage electrode and the collector, positive ions generated by the ionization effect are enriched towards the collector, electrons are enriched towards the high-voltage electrode, and a current signal is formed after the high-voltage electrode and the collector are led out to form an outer loop. The output current signal is weak (picoampere level), and is generally measured after passing through an operational amplifier, and the radiation dose rate value can be reversely deduced by measuring the current intensity of the output current signal because the intensity of the current signal is in direct proportion to the radiation dose rate under the same condition.
Scintillation detector: scintillation detectors are one of the commonly available detectors for high energy radiation detection. Scintillation detectors generally use as a detection material a scintillation crystal capable of effectively blocking and absorbing electromagnetic radiation and producing a luminescence effect with the electromagnetic radiation. When high-energy rays are incident into the scintillation crystal, according to the energy of the rays, the effective atomic coefficient and the density of the crystal, photoelectric effect, compton scattering effect and electron pair effect of different proportions are generated with the crystal, energy is deposited in the scintillation crystal, and the excited scintillation crystal is de-excited to emit scintillation light. The scintillation light in the visible or ultraviolet region is photoelectrically converted and multiplied by a photodetector such as a photomultiplier tube (Photomultiplier Tube, PMT) to form a pulse signal. The pulse signal intensity reflects the energy of the high-energy rays; the time of occurrence of the pulse signal reflects the incident time of the high-energy ray; the distribution of intensities of the pulse signals among the plurality of photomultiplier tubes reflects the incidence position of the high-energy rays, and the like. The scintillation detector has the characteristics of high detection efficiency, short resolution time and the like, and is widely applied to the research of nuclear medicine, security inspection, high-energy physics and cosmic ray detection.
