Description
Technical field
A kind of detection device for Soft Roll packing quality is the utility model is related to, specifically, the utility model is related to one
Kind lithium ion battery aluminum plastic film package quality detection device, particularly lithium ion battery aluminum plastic film package quality fast positioning detection
Device.
Background technology
Finished product flexible packing lithium ion battery is mainly made of parts such as naked battery core, electrolyte, aluminum plastic films.External aluminum plastic film
It is packing material, when encapsulation first seals lug side, then makees left and right sides heat-sealing and base heat-sealing successively.Because of finished product Soft Roll lithium ion
Electrolyte is stored in battery, so safe handling of the external aluminum plastic film heat seal quality to lithium ion battery has decisive influence.
At present, the industry, which is used for aluminum plastic film heat seal quality detection means, mainly two kinds, first, the thickness of aluminum plastic film edge sealing is directly measured,
Second, the tension intensity after test aluminum plastic film heat-sealing.Both detection means can only accomplish macroscopical detection, qualitative in time can sentence
Do not dispatch from the factory the heat seal quality of product.But both detection means can not detect the microdefect inside aluminum plastic film, cause to encapsulate
The product of quality defect smoothly dispatches from the factory, and electrolyte leakage easily occurs during user's use and triggers security incident.Chinese patent
Publication number CN03048376A discloses a kind of method for detecting flexible packing lithium ion battery internal corrosion, and this method uses voltmeter
The voltage between lithium ion battery plus-negative plate, and the voltage between anode ear and plastic-aluminum combined film layer are measured respectively, and make ratio
Compared with if the voltage and battery theoretical voltage value between anode ear and aluminium lamination are equal or smaller, the aluminium lamination in plastic-aluminum must occur
Corrosion.Or easier method is using the resistance between universal meter measurement anode ear and aluminum plastic film aluminium lamination, if measurement resistance
Value is less than 100, then has corroded.Although this method is very easy, practical, there are the problem of it is also very obvious, first is asked
Topic is detection cycle length, which must carry out on finished battery full power state, and need to shelve more than one day time；Second
A problem is not can determine that specific location, and this method can only judge whether aluminum plastic film corrodes, and can not determine aluminum plastic film
The specific location of corrosion, blind position detection are unfavorable for accurate judgement leakage point, add heavily to the difficulty of the work.
Utility model content
The utility model is grown mainly for prior art detection cycle, and can not determine that asking for corrosion sites occurs for aluminum plastic film
Topic, proposes a kind of simple in structure, detection simplicity, the lithium ion battery aluminum plastic film package quality fast positioning of accurate positioning detection dress
Put.
The utility model is achieved through the following technical solutions technical goal.
Lithium ion battery aluminum-plastic packaging quality fast positioning detection device, it includes power supply, conducting wire, switch, cathode folder, sulphur
Sour copper solution, anode and aluminum plastic film packaging bag.It is theed improvement is that：The anode is direct rod shape component, upper end through conducting wire and
Switch connection power supply, lower end is inserted among the copper-bath stored in aluminum plastic film packaging bag.The switch is open type.It is described
Power supply is through conducting wire connection cathode folder, and the cathode folder that oral area has pointed tooth clips broken aluminum plastic film packaging bag outer layer when folding, cathode folder is direct
Contacted with built-in aluminium lamination, establish closure power circuit by lower switch, form a kind of micro electrolytic cell, whether aluminium is adsorbed to copper
Plastic film packaging bag judges package quality.
As further improvement project, the voltage of the power supply is 6~8V.
As further improvement project, the switch 20~30min of closure energization during detection.
As further improvement project, the copper-bath is the concentration of mass fraction 15~25%.
The utility model compared with prior art, has the positive effect that：
1st, apparatus structure is reasonable, easy to operate, and testing result is accurate, reliable；
2nd, it is powered between the aluminium lamination and copper-bath of aluminum plastic film packaging bag and forms micro electrolytic cell, in electrolytic process
Copper is adsorbed to the region of aluminum plastic film packaging bag exception, this trace is easy to the quick heat seal quality for judging aluminum plastic film packaging bag, and
And the position of microdefect can be accurately positioned, so it is easy to the workshop technical staff operation to Heat-seal parameter or heat-seal equipment in time
State optimizes adjustment, so as to be conducive to improve follow-up heat seal quality.
Brief description of the drawings
Fig. 1 is structure diagram when the utility model is used to detect.
Embodiment
Below by attached drawing and in conjunction with the embodiments, the utility model is described in further detail.
Lithium ion battery aluminum plastic film package quality fast positioning detection device shown in the drawings, it include power supply 1, conducting wire 2,
Switch 3, cathode folder 4, copper-bath 5, anode 6 and aluminum plastic film packaging bag 7.The anode 6 is direct rod shape component, and upper end is through leading
Line 2 and the connection power supply 1 of switch 3, lower end are inserted among the copper-bath 5 stored in aluminum plastic film packaging bag 7, should in the present embodiment
Copper-bath is the concentration that mass fraction is 15%.The switch 3 is just pressed out when being open type, only examinations
Close 3.The power supply 1 connects cathode folder 4 through conducting wire 2, and the cathode folder 4 that oral area has pointed tooth is clipped broken outside aluminum plastic film packaging bag 7 when folding
Layer, cathode folder 4 are directly contacted with built-in aluminium lamination.During detection closure power circuit, the electricity of the present embodiment application are formed by lower switch 3
1 voltage of source is 6V.Once being powered between aluminum plastic film packaging bag 7 and copper-bath 5 just forms micro electrolytic cell, due to copper from
It is sub that electronic capability is stronger than aluminium ion, so the copper ion in electrolytic process in copper-bath 5 is adsorbed to aluminum plastic film encapsulation
7 abnormal areas of bag, and conduction time longer cupric ion adsorption is more, thus leaves obvious trace easy to quickly judge quilt
The heat seal quality of aluminum plastic film packaging bag 7 is surveyed, and quality defect point position can be accurately positioned.For anode, copper sulphate is molten
Hydroxyl in liquid 5 produces oxygen when discharging, so not influencing to detect quality.The utility model apparatus structure is extremely simple, real
With easily operated, it is most important that testing result is accurate, reliable.On the other hand, the present apparatus requires testing conditions low, is easy to
Detected in plant site, it is excellent to be so conducive to operating status progress of the workshop technical staff to heat-sealing technology parameter or heat-seal equipment
Change adjustment, can accomplish to avoid the production accident for producing batch defective work.
