fluctuation range is large, for electrokinetic cell lug, metallic conductor is wider, and high-frequency heating cannot ensure in the middle of conductor consistent with the homogeneous temperature at two ends, two ends and the mid portion temperature difference can differ larger, to the consistent encapsulation adhesion temperature that roomy lug can not obtain
also not timing sudden higher frequency can be there is and significantly reduces even idle situation in high frequency when using continuously, can automatically recover again a little while, this situation is generally difficult to find and judge, this production for continuous and automatic lug brings extreme difficulties, the defective products produced when high frequency does not work is difficult to find to remove, and causes severe compromise to battery.
Utility model content
For above deficiency, the utility model proposes a kind of hot-forming mechanism of lithium ion power battery pole ear, this equipment effectively can shorten the heat-sealing molding time of the large lug of power, excellent heat-sealing adhesion effect is provided, improve blob of viscose dimensional stability and outward appearance after hot pressing, be suitable for continuous prodution, enhance productivity.
The utility model is for solving the problems of the technologies described above by the following technical solutions:
A hot-forming mechanism for lithium ion power battery pole ear, comprises heater, hot pressing mechanism, and described hot pressing mechanism is surrounded by heater, is divided into upper, middle and lower three layers; The described lower surface on hot pressing mechanism upper strata and the upper surface of lower floor are equipped with hot pressing end socket, and described the upper and lower all connect a cylinder, make its can locking phase to movement.
Described heater comprises at least two group heating tubes, and often organize heating tube and be arranged on same limit, described heating tube is arranged towards lug metal tape to be heated.
Described heater comprises two groups of heating tubes, is separately positioned on the both sides of hot pressing mechanism; Described heater comprises support, heating tube angularly be installed on support, wherein often organize heating tube comprise upper and lower two heating tubes, upper heating tube is downward-sloping, and lower heating tube is inclined upwardly.
Described heating tube is gold-plated infrared shortwave heating tube.
The utility model adopts above technical scheme compared with prior art, has following technique effect:
1, this hot-press forming device adopts infrared shortwave heating tube to the heating of lug conductor rapidly, and stable being beneficial to of homogeneous heating monitors and detect, and improves lug product with stable quality;
2, this heating technique effect stability, improve the production efficiency of lug processing, production efficiency gets a promotion, and saves the energy;
3, be applied to by this equipment on the production line of the continuous and automatic of the large-scale lug of electrokinetic cell, make production and processing more efficient, product quality is more reliable and more stable, and tab and metallic conductor bonding strength better, can reach more than 15N/10mm.

Detailed description of the invention
The utility model provides a kind of hot-forming mechanism of lithium ion power battery pole ear, and for making the purpose of this utility model, technical scheme and effect clearly, clearly, and further describe the utility model with reference to accompanying drawing examples.Should be appreciated that concrete enforcement described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Be described in detail below in conjunction with the technical scheme of accompanying drawing to utility model:
The hot-forming mechanism of this lithium ion power battery pole ear, comprise the intermediate heat press mechanism and metallic conductor heating arrangements that tab and metallic conductor hot pressing are combined with each other, intermediate heat press mechanism is be provided with upper and lower two locking phases to the hot pressing end socket 1 and 2 driven by cylinder, the two groups of metal tape heating arrangements in left and right are respectively equipped with in above-mentioned hot pressing mechanism both sides, Mei Zu METAL HEATING PROCESS mechanism is equipped with upper and lower two heating tubes 3 and 4 and 5 and 6, be loaded in 45° angle on support, surface of the light tube distance surfaces of metallic strip vertical range 20mm, the power adjusting of four heating tubes is onesize, same group of two heating tubes are on vertical straight line, conductor both sides are fixedly installed in Eight characters sample, the horizontal range of heating tube distance end socket is 15mm.
While the tab feed mechanism of automatic lug molding machine starts feeding, infrared shortwave heating power supply is connected, start to heat metal tape, after feeding cylinder rollback adhesive tape is fixing, the action of intermediate heat press mechanism starts hot pressing, and the complete heat-sealing head return of pressing simultaneously, infrared heating pipe dump, stop heating, hot-forming lug pulls and is displaced to next station by equipment motor, send the feeding of lug sizing material cylinder, infrared heating pipe power supply is connected conductor heating, starts new once circulation.
Above-mentioned heating tube adopts gold-plated single-tube infrared shortwave heating tube, utilize the penetration power of infrared shortwave to heat inside and outside conductor hot pressing local location simultaneously, according to width and the thickness adjustment infrared heating tube power of lug conductor, after fluorescent tube is opened, the temperature at 8s inner wire hot pressing position reaches 180 DEG C or more (the molten point of tab is generally about 175 DEG C), the actuation time of this time match lug forming machine circulation, also namely terminate to complete to motor material drag from a hot pressing, infrared ray heating tube is started working, tab send glue to complete, on hot pressing mechanism, low head is closed starts hot pressing, glue and metal adhesive shaping, when hot pressing terminates end socket return, heating tube quits work.Adopt this mode of heating to heat up rapid safety, temperature controls easily and visible.
Wherein set infrared heating pipe and metal tape can be warmed to 140 DEG C-180 DEG C when heat-sealing head pressing, heat-sealing head design temperature is 150 DEG C-165 DEG C, and the hot pressing time is set as 3-6 second.
The hot-forming mechanism of this lug lithium ion power battery pole ear, can be used on various lug shaping mechanism, for a kind of common lug shaping mechanism, servo motor action drags metal material belt and arrives this hot pressing position, infrared heating pipe is started working simultaneously, lug sizing material is passed across heating platen and delivers to machine adhesive tape tool holding hand and fix by glue feeding device, on hot pressing mechanism, low head is closed starts hot pressing, when hot pressing terminates end socket return, heating tube quits work, first, second servo motor synchronization action drags material strip, metal material belt advances to this hot pressing position, hot-forming lug enters next station, start newly once to circulate.
Be understandable that; for those of ordinary skills; can be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, and all these change or replace the protection domain that all should belong to the claim appended by the utility model.
