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.
Summary of the invention
For above deficiency, the present invention 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 present invention 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 present invention 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.
