Description

A kind of aluminum hull lithium-ion electric core short-circuit detecting mechanism
Technical field
The utility model relates to battery core detection field, espespecially a kind of aluminum hull lithium-ion electric core short-circuit detecting mechanism.
Background technique
Lithium-ion electric core has part battery core because various reasons lead to battery core internal short-circuit during the manufacturing, this Partial short circuit battery core belongs to defective products, it is necessary to be screened by certain detection method, it is avoided to flow into process below Cause the loss that company is bigger.Aluminum current case lithium ion battery core is usually to use short-circuit test in assembly shop or Laser Welding workshop Instrument carries out short-circuit test to battery core, and certain voltage and resistance value is arranged in short circuit tester, and electric current is passed through positive and negative lead wires table Pen is drawn, and the positive and negative anodes test pencil of short circuit tester correspond to the positive and negative anodes of battery core by when test, one by one to battery core progress short-circuit test, When battery core resistance value is lower than short circuit tester setting resistance value, i.e., judgement battery core internal short-circuit, short circuit tester can issue report Alert prompt, so that short-circuit battery core be screened.
Due to needing to contact respectively with the positive and negative anodes of each battery core one by one, detection efficiency is low, in addition in Laser Welding process Before since aluminum hull and cover board do not carry out laser welding also, aluminum hull faucal is also in expansion state, just so as to cause battery core inside Cathode pole piece cannot be in close contact, and can not be screened completely to will lead to part and there is short-circuit hidden danger battery core.
Utility model content
To solve the above problems, the utility model provide it is a kind of raising detection efficiency and quality aluminum hull lithium-ion electric core it is short Road testing agency.
To achieve the above object, the utility model adopts the following technical scheme is: a kind of aluminum hull lithium-ion electric core short circuit Testing agency, including material box, fixture and short circuit tester, the interior arrangement of the material box are equipped with several battery cores, the battery core Equipped with positive terminal and negative pole end, the fixture be plugged in material box and with positive end in contact, the short circuit tester and fixture It is electrically connected, the short circuit tester is in electrical contact by cathode test pencil and negative pole end.
Preferably, the positive terminal is battery core shell, and the battery core cage connection has positive plate, and the negative pole end is battery core Rivet, the battery core rivet interlacement have negative electrode tab.
Preferably, the short circuit tester is equipped with positive wire and negative wire, and the positive wire is connect with fixture, institute It states negative wire and is connected with cathode test pencil.
Preferably, the battery core shell and fixture are aluminium, have good electric conductivity.
Preferably, the side of the fixture is triangular prism structure, empty between adjacent battery core when fixture is inserted into material box Gap can be smaller and smaller, so that flowing of the positive electric current on battery core shell can be improved.
The utility model has the beneficial effects that: by fixture contact with battery core and battery core between contact, short circuit survey Examination instrument connect all positive terminals that can connect with fixture by positive wire, recycles cathode test pencil respectively and in each battery core Cathode end in contact can be detected whether battery core is short-circuit, and structure is simple, positive and negative extreme with battery core respectively without using two test pencils Contact improves detection efficiency, and the extruding due to battery core by fixture, and the positive plate and negative electrode tab of battery core are in close contact, because This solves the problems, such as that battery core has short-circuit hidden danger and but is not detected among out, improves detection quality.
Detailed description of the invention

Fig. 2 is the structural schematic diagram of fixture.
Fig. 3 is the schematic diagram of material box installation battery core and fixture.
Description of symbols: 1. material box;2. fixture;3. battery core;31. negative pole end;32. positive terminal;4. short circuit tester; 41. cathode test pencil.
Specific embodiment
It please refers to shown in Fig. 1-2, the utility model is about a kind of 3 short-circuit detecting device of aluminum hull lithium-ion electric core, including object Magazine 1, fixture 2 and short circuit tester 4, the interior arrangement of the material box 1 are equipped with several battery cores 3, and adjacent battery core 3 contacts with each other, The battery core 3 is equipped with positive terminal 32 and negative pole end 31, and the positive terminal 32 is 3 shell of battery core, and 3 cage connection of battery core has just Pole piece, the negative pole end 31 are 3 rivet of battery core, and 3 rivet interlacement of battery core has negative electrode tab, and the fixture 2 is plugged in material box 1 It is contacted at the gap of battery core 3 and with 3 shell of battery core, the side of the fixture 2 is triangular prism structure, 3 shell of battery core It is aluminium with fixture 2, there is good electric conductivity, when fixture 2 is inserted into material box 1, gap can be more next between adjacent battery core 3 Smaller, the contact of adjacent 3 shell of battery core is more and more closer, so that flowing of the positive electric current on 3 shell of battery core can be improved, it is described Short circuit tester 4 is equipped with positive wire and negative wire, and the negative wire is connected with cathode test pencil 41, the short circuit tester 4 are electrically connected by positive wire and fixture 2, and the short circuit tester 4 is in electrical contact by cathode test pencil 41 and negative pole end 31.
The utility model by fixture 2 contacted with battery core 3 and battery core 3 between contact, short circuit tester 4 passes through anode Lead connect all positive terminals 32 that can connect with fixture 2, recycle cathode test pencil 41 respectively with the negative pole end in each battery core 3 31 contacts, can be detected whether battery core 3 is short-circuit, and structure is simple, terminate respectively with the positive and negative anodes of battery core 3 without using two test pencils Touching improves detection efficiency, and the extruding due to battery core 3 by fixture 2, and the positive plate and negative electrode tab of battery core 3 are in close contact, because This solves the problems, such as that battery core 3 has short-circuit hidden danger and but is not detected among out, improves detection quality.
