Description
Technical field:
This utility model relates to the measurement of a kind of case hardness, is particularly well-suited to battery technology production application field.
Background technology:
In lithium ion battery production technology, inside battery is by positive pole, negative pole, release paper, the big main portion of electrolyte four
Dividing and constitute, outside is to be completed encapsulation by aluminum plastic film through hot pressing, through chemical conversion, partial volume, completes the production work of whole battery
Skill.And to check through multiple tracks in process of production, to ensure that the battery produced meets production engineering specifications.Wherein battery
Through chemical conversion, after partial volume, detection battery surface hardness is important to detect operation together.Lithium ion battery must reach one
Fixed hardness, its objective is: (1) only has its hardness to reach requirement, and just explanation battery is in process of production, does not has too much suction
Receive moisture content, production environment safety is described, safely provide premise guarantee for the battery later stage；(2) its hardness is only had to reach to want
Asking, just explanation inside battery does not has unnecessary gas, just can prove that cell activation is abundant, could provide for the performance in battery later stage
Ensure；(3) only having its hardness to reach requirement, just explanation cell package effect is intact, and guarantee battery used in the later stage
During will not because of with contacting external air, cause active matter occur polarization and cause battery normally not use.
And the most also do not have a kind of equipment to disclosure satisfy that the requirement measuring battery surface hardness at present, similar common
Durometer, is the most all to measure nonferrous materials or other components and parts, and similar this class formation of lithium ion battery
Product, according to this type of device measuring, not only results in product surface and scratches, and cannot meet the requirement of one-hundred-percent inspection.Existing
Way commonly used in enterprise is that employee presses by pinching with hands or by the way of percussion battery surface, sentences with sensation or experience
Whether disconnected hardness reaches the requirement of design.This type of way: one is to ensure that employee the most really completes the detection of this road, does not has
According to looking into；Two is everyone maneuver difference, and power is different, and experience is different, and the result obtained also can be had any different, and then can shadow
Ring later stage battery with two side terminals.
Summary of the invention:
Task of the present utility model is that a kind of measurement structure of proposition is simple, manufactures and processing ease, and avoids artificial
Factor brings a kind of lithium ion battery surface hardness measurement system of error.
Task of the present utility model is done in such a way that it includes tup and handle, it is characterised in that: the sky of described tup
Near end equipped with cushion in chamber, on cushion, adhesion has pressure transducer, and the centre of pressure transducer closely cooperates placement
Have a probe, probe be placed with wireless communication module, described wireless communication module by connection pressure transducer and
Probe, the outfan of described wireless communication module is connected with central processing unit, and described central processing unit passes through plug and computer
Main frame is connected.Described cushion selects wearable elastic pad, and its material is natural gum or synthetic rubber, and described pressure transducer is selected
Centre is empty pressure sensitive sheet.The thered is provided supply voltage of described wireless communication module is 3.6V, and described central processing unit passes through
USB plug is connected with host computer.
This utility model has the effect that the technical program avoids and manually pinches pressure at present, beats mode, judges
The hardness of battery, it is to avoid the error that anthropic factor brings.
Accompanying drawing illustrates:
Fig. 1 is to measure its exterior structural representation；Fig. 2 is to measure circuit system frame structure schematic diagram.
Drawing illustrates: 1, cushion, 2, pressure transducer, 3, probe, 4, wireless communication module, 5, tup, 6, handle.
Detailed description of the invention:
The technical program is to use to tap a hammer, makes the wearable elastic pad contact lithium ion bottom percussion hammer by handle
Battery surface, makes cushion deform, and the principle rebounded by power senses the hardness on measured body surface, and bounce is passed through
Pressure transducer is by a pressure, and the probe being in close contact with cushion also can sense the deformation of cushion, and with pressure
The wireless communication module that force transducer and probe connect, sends another parts central processing unit, by central processing unit by data
After reason, the result drawn can be stored directly in computer, it is simple to inquires about, contrast and the later stage is reviewed.
Specific embodiment is as it is shown in figure 1, tap hammer and be made up of tup 5 and handle 6, near end in the cavity of described tup 5
Portion is equipped with cushion 1, and on described cushion, adhesion has pressure transducer 2, described pressure transducer closely to connect with cushion
Touching, the centre of pressure transducer closely cooperates and is placed with a probe 3, and probe 3 is placed with wireless communication module 4, described nothing
Line communication module passes through connection pressure transducer and probe, and described cushion preferred wearable elastic pad, its material can be
Natural gum, it is also possible to be synthetic rubber, if material is different, the data analysis system in central processing unit also differs.Described pressure
Force transducer is the pressure sensitive sheet in the middle of selecting for sky, and the vertical direction of described tup is equipped with handle.The described hammer that taps is similar to
Rubber hammer.
Pressure transducer as shown in Figure 2 and probe are connected with wireless communication module by circuit, described wireless telecommunications mould
The outfan of block is connected with central processing unit, and described central processing unit is connected with host computer by plug, described channel radio
News its provided supply voltage of module is 3.6V, and its charger can use the charger of 3.6V-4.8V common on market to fill
Electricity；Described central processing unit includes voltage signal conversion and data analysis, and described central processing unit is by similar USB plug
Form is connected with host computer.
During work, tap battery surface by tapping hammer, send two signal sources: one is due to the pressure of cushion adhesion
Sensor, force value F1 sensed；The voltage signal that two is the deformation sensing measured object by cushion of popping one's head in, voltage
Signal and force value F1 are sent to central processing unit by wireless communication module, and central processing unit turns through data analysis and data
Changing, draw the superficial hardness number of measured object battery, its numerical value is received in host computer by the USB two of central processing unit,
And be automatically saved in electrical form, it is simple to result queries and comprehensive descision, it is to avoid manually pinch pressure at present, beat mode,
Judge the hardness of battery, thus avoid the error that anthropic factor brings.
