Abstract
What electric battery with plastic case related to is the manufacture of casing of the serial dried battery of zinc-manganese and chromium-nickel series battery, replace the paper shell continue to use at present and the traditional material of iron sheet shell with plastics, materials such as its available poly-third ethene are injection molded into moulds shell, will not have the rolled tin of packing battery and packs into to mould and be packaged into the battery finished product in the shell.The present invention has not only simplified original production process, mainly is that the anticorrosion and leakage to battery is improved, and improves the storage and the useful life of battery, saves a large amount of black sheet iron materials, has reduced battery cost.
Description
The present invention is a kind of battery case manufacture method, changes the traditional material of battery case, substitutes present paper shell and iron-clad with plastic casing, is applicable to serial dried battery of zinc-manganese and chromium-nickel series battery.
At present, battery case is that papery and tinplate material are made, especially iron-clad occupies the majority, with the iron-clad is example, it begins with the label process of tinplate material, till the finished product packing warehouse-in, and be through the nearly 30 road technologies of size, complex process, personnel selection is many, equipment investment is also bigger, especially in process for making shell just like according to technology destructible tinplate overlay coating and enamelled coatings such as mouth, pressing, pressure hook muscle.Like this, battery deposit with use in easily oxidation, then with regard to easy-to-leak liquid, influenced the quality and the useful life of battery, even can damage torch.The tinplate used of China needs import in addition, and flower is got a large amount of foreign exchanges, increases cost and influences economic benefit.
Purpose of the present invention is exactly tinplate and the paper material that replaces the current battery shell to use with this new material of plastics, the storage and the useful life of improving battery simplifies original production process, reduces cost, and increases economic efficiency.
The material that the shell of electric battery with plastic case adopts is plastics such as the rare or polyphenyl of poly-third second, polyvinyl chloride.The technology that it is made is: at first be batching, add Cornstarch and inserts and small number of curing agents in poly-third second is rare, be the tie rod technology of heating then, be then again be ground into granular, thereafter the top cylinder of injection casing and base ring on injection molding machine, see accompanying drawing 1, it is divided into top cylinder (1) and base ring (2), middle joining place is that top cylinder (1) puts a bit of overlapping of base ring (2), after the linking in, external diameter and top cylinder (1), base ring (2), interior external diameter unanimity, internal diameter is the same with no battery pack (semi-finished product) external diameter certainly, after being injection molded into top cylinder (1) and base ring (2), carry out packed battery technology, rolled tin is not had the battery pack upper surface put insulating lid, be inserted in top cylinder (1) then from the upper end, after the negative pole egative film is put into base ring (2), be connected the section outside and coat plastic binder, be inserted in from no battery pack lower end then, and bonding with top cylinder (1) section of linking, like this, no battery pack tightly is inserted in to be moulded in the shell, moulds the thickness of shell and decides on battery label difference, conforms with national standard with the battery external diameter and is as the criterion.The same with iron(-)clad battery then, the polypropylene film thermoplastic that will be printed on trade mark is sleeved on moulds the shell outside, and such electric battery with plastic case is just made successfully.The shell in electric battery with plastic case pond begins to put in storage to the packing of finished product with batching, only eight procedures.Another kind method is moulded shell and also be can be made into as the tubular on interior edge is arranged on Fig. 2, and half-finished no battery pack is inserted in from the bottom, then negative plate is put into from the bottom, and thereafter, heating in one of invagination along (along dotted portion) in the bottom, presses negative plate and also can.This method is suitable for the serial dried battery of zinc-manganese and chromium-nickel series electric power storage battery.
The present invention has simplified production technology, improved outmoded production technology, save many process equipments and personnel, improved production efficiency, secondly owing to replace papery and irony with plastics, anticorrosion and leakage to battery is improved, improved the storage life of battery, even the useful life of also having improved torch, also having saved a large amount of black sheet irons and foreign exchange in addition, the more important thing is and reduced cost greatly low, is example with No. 1 dry cell, every cost only is half of body paper shell and iron-clad, and economic benefit is appreciable.If cost is constant, the cost of shell saving is increased to electrolytic manganese in the anode formula, the electrion time can prolong 60-90 minute.
The inventor is according to the shell of the structure injection moulding of accompanying drawing 1, is enclosed within on No. 1 semi-finished product dry cell, moulds about the thick about 1mm of shell wall, conforms with national standard.Spillage of material reduces.Equipment investment also reduces 2-3 doubly, and personnel also use many less, have shown good economic benefit and social benefit.
Claims (4)
1, electric battery with plastic case relates to the manufacture of casing of the serial dried battery of zinc-manganese and chromium-nickel series battery, it is characterized in that:
Shell is to use the plastics manufacturing, and with batching, heat, technologies such as pulverizing, injection moulding, packed battery, suit trade mark manufacture electric battery with plastic case.
Shell is the plastics manufacturings, and it is injected into top cylinder (1) and base ring (2), and rolled tin does not have battery pack and tightly is inserted in and moulds in the shell.
2, electric battery with plastic case according to claim 1 is characterized in that: mould the tubular that shell also can be injected into interior edge.
3, according to claim 1 and 2 described electric battery with plastic case, it is characterized in that: moulding shell can be with gathering plastics such as third ethene, polystyrene, polyvinyl chloride.
4, according to claim 1 and 2 described electric battery with plastic case, it is characterized in that: after no battery pack tightly was inserted in and moulds shell, the thickness of moulding shell was as the criterion through conforming with national standard in addition.
