Description
Technical field
The utility model relates to the detection field of lithium ion battery, more specifically a kind of electrodes of lithium-ion batteries head and the tail thickness detection apparatus.
Background technology
Lithium ion battery has the advantages such as voltage is high, energy is high, recycle often, storage time is long, not only on portable electric appts, be used widely such as mobile phone, Digital Video and laptop computer, and be widely used in the big-and-middle-sized electrical equipment aspects such as electric automobile, electric bicycle and electric tool, therefore more and more higher to the safety requirements of lithium ion battery.
Electrode plates is the important component part of lithium ion battery, is the core of lithium ion battery, and the production of battery pole piece will starch, apply, rolls and the operation such as shearing through powder, is one of operation of wherein key and roll.The critical control point that rolls rolls thickness exactly, if roll thickness abnormity, will directly affect the quality of pole piece, so the thickness measure for pole piece is vital, and the head and the tail place difference in thickness of pole piece is the important indicator in the production run, is the key factor that affects production efficiency so fast and accurately the head and the tail thickness of pole piece is carried out Measurement accuracy.
And at present in production practices, also do not have specially pole piece to be measured the pick-up unit of head and the tail thickness difference, and all be to carry out independent measurement by operating personnel with milscale is manual, such metering system has a lot of drawbacks:
At first, hand dipping speed is slower, affects the batch production speed of product, reduces production efficiency.
Secondly, hand dipping is had relatively high expectations to operating personnel's, needs skillfully to use milscale, if improper use will cause the batch accident of product.
The 3rd, the hand dipping accuracy can not well guarantee, owing to artificial factor is easily made a fault, thereby causes the bad of product.
So be badly in need of now wanting a kind of both easy, quick, can accurately measure again the pick-up unit of pole piece head and the tail thickness difference, improve the production efficiency of product, to adapt to the batch production of product.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of pick-up unit that solves present hand dipping electrodes of lithium-ion batteries head and the tail thickness is provided.
The technical matters that the utility model solves takes following technical scheme to realize: comprise handle, display screen, body, with milscale and the sounding rod of measuring knob, described handle is fixedly connected with described body, the lower end of described milscale is provided with the measurement mobile jib, described measurement mobile jib be connected sounding rod and connect by connecting link, described milscale and described connecting link are arranged in the inner chamber of the described body first half, and described sounding rod and described body are slidingly connected.
The Lower Half of described body is provided with C shape groove.
The bottom margin place of described C shape groove is provided with the measurement boss.
The quantity of described sounding rod is five.
Described display screen be arranged on described body above.
The utility model compared with prior art has significant advantage and beneficial effect, is embodied in the following aspects:
1 uses the utility model to solve the slow problem of hand dipping, has improved detection speed, is conducive to product and expands the scale of production.
2 use the utility model have solved the problem of hand dipping poor accuracy, have guaranteed the quality of production of pole piece, have eliminated finished product cell safety hidden danger.
It is more directly perceived that being arranged so that of 3 display screens detected data, convenient record statistics.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the connection diagram of the utility model milscale and sounding rod.
Among the figure: 1. measure knob, 2. sounding rod is 3. measured boss, 4. groove, 5. handle, 6. body, 7. display screen, 8. milscale, 9. measurement mobile jib, 10. connecting link.
Below in conjunction with drawings and Examples the utility model is described in detail.
Embodiment
Below in conjunction with accompanying drawing 1-2 the utility model embodiment is further described:
A kind of electrodes of lithium-ion batteries head and the tail thickness detection apparatus, comprise handle 5, display screen 7, body 6, milscale 8 and sounding rod 2, handle 5 is fixedly connected with body 6, display screen 7 be arranged on body 6 above, the lower end of milscale 8 is provided with measures mobile jib 9, measuring mobile jib 9 is connected with sounding rod by connecting link 10 connections, milscale 8 and connecting link 10 are arranged in the inner chamber of body 6 first halves, sounding rod 2 and body 6 are slidingly connected simultaneously, be provided with above the milscale 8 and measure knob 1, wheel measuring knob 1 during detection, sounding rod 2 is to downward-extension, thereby the head and the tail to pole piece are measured, and the data of milscale 8 namely can be presented on the display screen 7, and the thickness difference of pole piece just can be read very clearly.
The Lower Half of body 6 is provided with C shape groove 4, during detection pole piece is put into groove 4 and detect, the bottom margin of C shape groove 4 is provided with measures boss 3, as the supporting role of pole piece, the quantity of sounding rod 2 is 5, can measure fast and accurately the thickness of pole piece head and the tail.
Testing process: at first grasp handle 5, the C shape groove 4 of body is kept parallel with the tape transport pole piece, sounding rod 2 is aimed at the position that the head and the tail of pole pieces need to be measured, another hand rotation measuring knob 1, at this moment five sounding rods 2 descend simultaneously pole piece are carried out thickness measure, at this moment measurement result is simultaneously displayed on the display screen 7, at this moment the thickness difference of pole piece reading of clear and definite very just, so just can in time rapidly underproof pole piece be found, in order to avoid cause the defective products of pole piece to affect product quality.
Utilize technical scheme described in the utility model, or those skilled in the art designing similar technical scheme under the inspiration of technical solutions of the utility model, and reach above-mentioned technique effect, all is to fall into protection domain of the present utility model.
