Abstract
Lithium ion battery diaphragm hot cutting device, molybdenum filament pass the electrical pillar that leads at both ends, and the both sides of leading electrical pillar respectively are connected with positive cathode conductor, and the guide pillar support piece that electrical pillar was led at the support both ends installs at the vaulting pole face to face to the distribution is at its both ends, and to realize whole device level or vertical direction translation, be provided with below the vaulting pole and drive actuating cylinder and guider, drive that actuating cylinder and guider are whole to be fixed on the mounting panel, heat to the temperature more than the fusing point of diaphragm after, again control drive the whole vaulting pole of actuating cylinder drive and make the molybdenum filament quick approach and pass the diaphragm, make the diaphragm receive thermal fuse in the twinkling of an eye, reach fervent effect.
Description
Technical field
The barrier film that this utility model is related in lithium ion battery production equipment, more particularly to lithium ion battery cell manufacture is cut
Disconnected device.
Background technology
In the production process of lithium ion battery, battery core manufacture is very crucial operation.At present in single battery core manufacture every
Film cut-out has cold cut and fervent two ways.Cold cut is mechanically slipped in barrier film off-position with blade, and this mode is most
Big shortcoming is that cutting knife is easy to wear, and barrier film cuts not to be a line, and the easy damaged barrier film in the case of cutting knife is stubbed；Earnestly
It is the melting temperature that so-called cutting knife is heated to barrier film, is barrier film fusing, fervent cutting knife is really a kind of resistant to elevated temperatures gold
After category silk, but tinsel high-temperature heating, easy lengthening deformation, causes barrier film misaligned when fusing, and causes barrier film cut-out not conform to
Lattice.Earnestly convenient than cold cut on the whole, the simple structure of device, notch effect are better than cold cut, and efficiency high.Therefore, enter one
It is technical problem to be solved that step improves fervent quality and efficiency.
The content of the invention
The purpose of this utility model is to solve the earnestly easy lengthening deformation of middle tinsel, improves the fervent quality of barrier film and efficiency,
A kind of lithium ion battery separator hot-cutting device is provided.
The technical solution adopted in the utility model is：Lithium ion battery separator hot-cutting device, sets at the two ends of triatic stay
There is the support member for supporting conductive pole, conductive pole both sides connect positive and negative electrode wire respectively；There is a horizontal mounting plate to fix below strut
Drive cylinder and guider, the outside of two ends conductive pole are equipped with a spring, and there is a nut inboard, and molybdenum filament is from the conductive pole of two ends
Between groove through electrically connecting with wire.Molybdenum filament coefficient of thermal expansion is little, and molybdenum filament remains linear state under the action of the spring, drives
Cylinder and guider realize the movement of whole device horizontal or vertical direction.
The beneficial effects of the utility model are that one is because molybdenum filament thermal coefficient of expansion is less very than other tinsel thermal coefficient of expansions
It is many, therefore the length change of molybdenum filament is little after heating.Two be conductive pole make molybdenum filament heating it is elongated when, as the effect of spring can make molybdenum filament
Remain linear state.
Description of the drawings
With reference to the accompanying drawings and examples this utility model is illustrated:
Fig. 1 is this utility model structural representation；
Fig. 2 is this utility model partial enlargement（Molybdenum filament is installed）Figure.
In figure：1 molybdenum filament, 2 nuts, 3 springs, 4 conductive poles, 5 guide pillar support members, 6 struts, 7 drive cylinders, 8 are oriented to dress
Put, 9 installing plates, 10 wires.
Specific embodiment
As shown in figure 1, lithium ion battery separator hot-cutting device, the two ends of triatic stay 6 are provided with the support for supporting conductive pole 4
Part 5, strut 6 have a horizontal mounting plate 9, drive cylinder 7 and guider 8 to be fixed on installing plate 9 below, realize whole device
Horizontally or vertically direction movement；There is spring 3 on the outside of two ends conductive pole 4, there is nut 2 inboard, and molybdenum filament 1 is from two ends conductive pole 4
Between groove pass through, 4 side of conductive pole connection positive wire 10, the negative level electric wire of opposite side connection 10.
Operation instruction：Prepare the molybdenum filament of diameter 0.2mm certain lengths, groove of the molybdenum filament 1 from the middle of two ends conductive pole 4 is worn
Cross, spring 3 is enclosed within the outside of conductive pole 4 to offset molybdenum filament because heating and the length that stretches repeatedly, nut 2 makes the conductive pole will not be because
Spring force and eject.4 side of conductive pole connects positive wire 10, and level electric wire 10 is born in opposite side connection.Need to connect before cutting barrier film
Wire 10 heats molybdenum filament 1, after being heated to the temperature more than fusing point of barrier film, then controls drive cylinder 7 and drives whole strut 6 to make
1 fast approaching of molybdenum filament simultaneously passes through barrier film, barrier film moment to be heated and fuse, and reaches fervent effect.
