Description
Technical field
The present invention relates to battery core hardness measurement technology, in particular to a kind of test device of battery core hardness.
Background technique
The measuring technology of battery core hardness has swing ball hardness measurement hardness, rebound method to survey hardness at present, but the prior art is deposited
In following problems:
(1): current device measuring is not fine enough, can only generally measure the hardness of some position of battery core；
(2): swing ball method and rebound method are all to go to hit testee using bead, it is contemplated that the hardness of battery core itself
It is not particularly greatly that such method measurement error is larger, for example may be used to the small club hit and stop rebound.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of test device of battery core hardness.
To achieve the above object, the specific technical solution of the present invention is as follows:
A kind of test device of battery core hardness, comprising: pedestal, bracket, stationary fixture, the master controller shown with data,
And the rotation swingle of stationary fixture, the prill of several suspensions, several strength on bracket are set and experience instrument；Each strength
Experience instrument end to be correspondingly arranged in the direction of motion of a prill, when stationary fixture load battery core is rotated by 90 °, rotation
Battery core after turning can touch prill；The master controller control swingle rotation, drives the battery core on stationary fixture
Prill is hit in rotation, and the strength, which is experienced, feeds back to master control for the impact force experienced after instrument is hit by prill
Device judges the hardness of battery core accordingly.
Preferably, which further includes a first connecting rod, several swing rods, and each prill connects via a swing rod
It is connected on first connecting rod, which can move up and down along bracket.
Preferably, which further includes one second connecting rod, and several strength experience instrument and are fixed on second connecting rod
On, which can move up and down along bracket.
Preferably, all prills are located in same horizontal line.
Preferably, when stationary fixture load battery core is rotated by 90 °, postrotational battery core is at folded position to two sides
Bead is hit at 1/3~1/2.
Preferably, the width of the stationary fixture is the 1/5~1/10 of battery core width.
Using technical solution of the present invention, have the advantages that
A point of battery core is only measured when prior art general measure hardness, the present invention can be whole by entire battery core multiple spot
Measurement, measurement is convenient, and visual result is convenient for comparing.Measurement battery core hardness often fixes battery core compared with the existing technology simultaneously
It goes to measure with measuring instrument again, the present invention is to obtain its hardness number using the movement of battery core itself, and obtained hardness number is more
Add and match with actual hardness value in actual use, because the requirement in relation to hardness is not often solid to battery core in actual use
When determining state, but when being kept in motion.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the working principle of the invention figure.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
Referring to figs. 1 to shown in Fig. 2, the present invention provides a kind of test device of battery core hardness, comprising: pedestal 15, bracket 16,
Stationary fixture 2, the master controller 14 shown with data, and the swingle 3, several that stationary fixture 2 is rotated on bracket 16 is set
The prill 4 of suspension, several strength experience instrument 7；Each strength experiences the fortune that 7 end of instrument is correspondingly arranged at a prill 4
On dynamic direction, when the stationary fixture 2 load battery core 1 is rotated by 90 °, postrotational battery core 1 can touch prill 4；
The master controller 14 controls swingle 3 and rotates, and the rotation of battery core 1 on stationary fixture 2 is driven to hit prill 4, the power
Amount, which is experienced, feeds back to master controller 14 for the impact force experienced after instrument 7 is hit by prill 4, judges the hard of battery core accordingly
Degree.
As an of the invention optimal technical scheme, which further includes a first connecting rod 5, several swing rods 6, each
Prill 4 is connected on first connecting rod 5 via a swing rod 6, which can move up and down along bracket and adjust its height
Degree.
As an optimal technical scheme of the invention, which further includes one second connecting rod 8, and several strength experience instrument
7 are fixed in second connecting rod 8, which can move up and down along bracket and adjust its height.
Specifically, it is equipped with sliding groove 9 and sliding groove 10 in first connecting rod 5,8 corresponding position of the second connecting rod on bracket,
First connecting rod 5, the second connecting rod 8 are connected to master controller 14 via connecting rod control line 12 respectively and are controlled by it.It is described
Swingle 3 is connected to master controller 14 via swingle control line 13 and is controlled by it.
As an optimal technical scheme of the invention, all prills 4 are located in same horizontal line.In the fixing clamp
When 2 load battery core 1 of tool is rotated by 90 °, postrotational battery core hits bead at the 1/3~1/2 of folded position to two sides.
As an optimal technical scheme of the invention, the width of the stationary fixture 2 is the 1/5~1/10 of 1 width of battery core.
In the present invention, the angle that swingle 3 drives battery core 1 to rotate is defined as 90 °, and the speed for driving battery core 1 to rotate is general
For 100~200rpm.The impression face that strength experiences instrument 7 is preferably circular, when prill 4, which strikes strength, experiences instrument 7
It waits, strength experiences instrument meeting 7 and numerical value is transmitted to master controller 14 by data line 11, and master controller 14 has display, display
Device can show the size of the stress of each small ball impact.Because of the soft or hard difference of the soft or hard difference of battery core and each place,
The numerical value that prill 4 is hit can be different, so that the soft or hard situation to judge battery core 1, hits when different prills 4
Then think that battery core has phenomenon of feeling like jelly when numerical value differs by more than 10%.
When the striking face of the height and overturning battery core 1 that ceaselessly adjust prill 4, battery core more than 1 time shock metal
The shock force value of the acquisition different location of bead 4, so that it may all measure the hardness of entire battery core 1；Simultaneously in order to anti-
Only prill 4 swings back and forth the shock to battery core 1, and when battery core 1 hits prill 4 for the first time when measurement, strength experiences instrument 7
After having read the strength numerical value of shock, swingle 3 can control battery core 1 and return on initial horizontal plane, while master controller 14 is controlled
Swing rod 6 processed allows prill 4 to stop swinging, and facilitates and continues to measure 1 other positions of battery core.
The following are testing example
