Abstract
This invention relates to an improvement mthod for production procedures of cylinder Li ionic cells including adjusting the manufacture procedure to the following one: winding-assembly-cleaning-printing codes-formation-selection-installing a pyrocondesed jacket-package, 2, printing a code on the shell of a cell, in which, a formation protection board is set on the surface of a formation tray.
Description
Technical field
The present invention relates to a kind of to cylindrical battery, the particularly improvement of lithium ion battery manufacturing process.
Background technology
Before the present invention realized, the manufacturing process flow of existing cylindrical lithium ion battery comprised coiling-assembling-cleaning-go up thermal shrinkable sleeve-beat yard-change into-sorting-packaging process successively.In above-mentioned operation, after battery is assembled, need clean battery surface, go up the thermal shrinkable sleeve operation then, but thermal shrinkable sleeve is handled on carrying out immediately after the cleaning, make battery in the flowing of follow-up each operation, increase the wearing and tearing of thermal shrinkable sleeve easily, and then to product quality generation harmful effect; In addition, after the thermal shrinkable sleeve operation was carried out pyrocondensation to battery on the process, the thermal shrinkable sleeve of battery was easy to occur bad order or breakage at formation process thereafter or under hot environment, causes defect ware; Beat a sign indicating number operation and generally all after last thermal shrinkable sleeve operation, finish, be easy to make in the every operation that is coded in thereafter after on thermal shrinkable sleeve, beating yard be worn, be unfavorable for reviewing battery.Use the above-mentioned background technology to make the quality problems that battery is easy to produce battery.But this operation is again the indispensable operation that lithium ion battery is made, and therefore in time adjusts the above-mentioned manufacturing process in the background technology, and it is crucial particularly adjusting and going up the process sequence of thermal shrinkable sleeve operation in whole cylindrical lithium ion battery.
Summary of the invention
The objective of the invention is by improving one's methods of a kind of cylindrical lithium ion battery production technology is provided, and then solved the problem that exists in the above-mentioned background technology.
Technical solution of the present invention is: state the manufacture craft condition of above-mentioned background technology in the use, manufacturing process has been carried out following adjustment and improvement:
1. described battery manufacturing process is adjusted into: coiling-assembling-cleaning-beat sign indicating number-change into-sorting-go up thermal shrinkable sleeve-packing.
2. will beat a yard operation and be arranged at after the matting, before the formation process, directly on the housing of battery, beat sign indicating number, can significantly reduce owing on thermal shrinkable sleeve, beat the drawback that sign indicating number brings.
Because the inventive method will go up the thermal shrinkable sleeve operation and be arranged at after the formation process, make the battery that charges in formation process can not obtain the protection of thermal shrinkable sleeve, make battery be easy to generate short circuit in manufacture process.Therefore used the frock of a special use at formation process, the basic structure of this frock is that the tray upper surface that changes in known formation device has increased by one and changes into baffle.The described upper surface that changes into baffle is provided with several circular holes, and this circular hole is corresponding with the described circular hole that changes on the pallet, and is on the same axis.The said structure of frock can make the last probe of formation device touch the positive pole of battery by this hole and can not touch other positions of battery, and then prevent that distortion owing to last probe from touching the short circuit phenomenon that cause at other position of battery, carries out charging process smoothly.
Above-mentioned operation of the present invention is improved one's methods and need not be adjusted the corresponding manufacturing process of each operation in the background technology, the percent defective and the product repair rate of battery manufacture process have been reduced, reduce production cost of cells and labour intensity, can effectively prevent the generation of short circuit phenomenon in the charging process simultaneously.
Description of drawings
Accompanying drawing 1 is the structural representation of special tooling of the present invention under user mode;
Accompanying drawing 2 is the vertical view of accompanying drawing 1.
Execution mode
Below in conjunction with accompanying drawing, the structure of using among the present invention that changes into pallet and change into baffle is further described.
Embodiment
Shown in accompanying drawing 1,2,1 is the last probe on the formation device, is fixed in the known formation device, and it will be corresponding with anode; 2 for changing into baffle, can make by known fire proofing material, and plate is provided with 256 circular holes; 4 are the pallet that changes in the known technology, and the position that wherein can insert battery can be corresponding with the above-mentioned circular hole that changes on the baffle with quantity, changes into and can insert the battery 3 of not going up thermal shrinkable sleeve in the pallet; 5 is the following probe on the above-mentioned formation device, and it is corresponding with battery cathode.Described upward probe, following probe, battery should be on the same axis.During use; earlier battery is put into and changed into pallet, will change into baffle then and cover and changing on the tray upper surface, will change into pallet and put into formation device; make the positive pole of the last probe contact battery of formation device, the negative pole that following probe contacts battery respectively can charge.The effect that changes into baffle here is that it can make probe only contact the positive pole of battery, has prevented because the distortion that last probe produces in repeatedly using causes the generation of battery short circuit situation.Changing into baffle in addition can also be when the contingency of battery abnormal heating grade on fire takes place, to other batteries and equipment are protected on every side.
