Description

A kind of protective device and pecten of welding of lead-acid storage batteries terminal
Technical field
This application involves lead-acid storage battery production apparatus field, more particularly to a kind of the anti-of welding of lead-acid storage batteries terminal Protection unit and the pecten using the protective device.
Background technology
Lead-acid storage battery terminal leakproofness is most important to battery performance and service life, at present glue envelope and part lead-acid accumulator Terminal is to be welded together bus-bar and terminal pole by welding gun, is then covered, and forms the terminal sealing knot of accumulator Structure, therefore the welding quality of accumulator terminal is very crucial.
In existing production, the method that the comparison of freezing of terminal and bus-bar is traditional is to enter the mode of shell by hand, will pole group After cast welding is good, in the loading battery case of one pole group of a pole group, two side pole groups are also to take to freeze terminal to be packed into electricity afterwards In the shell of pond, at this point, when being welded to terminal and bus-bar, due to welding gun freeze that the time is long or bus-bar and pecten it Between be combined with gap lead liquid caused to leak down, can all there are problems that scalding battery, lead to fraction defective.Also, enter the side of shell by hand Formula, not only low production efficiency, but also very high to the technology requirement of operating personnel are careless slightly to may result in defective products.
In order to improve production efficiency, the problems such as antipole caused by avoiding filling by hand during shell is short-circuit, battery production is ensured The stability of quality, method more advanced at present are that, using automatic dress shell structure, the pecten to freeze is also changed to and battery case The structure of cooperation.But the thickness of gap or bus-bar is combined between time length, bus-bar and the pecten to freeze due to welding gun Situations such as differing, can also cause there is leakage lead problem during freezing, and the lead liquid of leakage touches battery case, causes to scald.For this purpose, In process of production, in order to avoid or reduce leakage lead, the operating personnel having when freezing dare not be big by thermal transfer, cause to freeze only will Bus-bar surface and terminal susceptor surface welding, the deeper of the two cause easily to go out in high current also in discrete state Situation about being now broken.Therefore, either enter shell by hand or fill shell automatically, can not all avoid leakage lead completely, it is bad in order to reduce Rate, it is necessary to avoid scald of the leakage lead to battery case using other approach.
Invention content

Preferably, elastic parts includes spring 3 and T-shaped lead 4, and T-shaped mounting hole 5 is offered on fireguard 1, T-shaped to lead T-shaped mounting hole 5 is passed through to be fixedly connected with fixed limited block 2 to column 4, fireguard 1 can be moved left and right along T-shaped lead 4;Spring 3 are placed on T-shaped lead 4, and spring 3 is located between fireguard 1 and fixed limited block 2.
It should be noted that the application preferably forms elastic parts using spring 3 and T-shaped lead 4, fireguard is realized 1 elastic connection with fixing limited block 2, wherein the effect of T-shaped lead 4 is to limit the movement locus of fireguard 1, fireguard 1 It can only be moved left and right on T-shaped lead 4, and spring 3 then provides elastic force for fireguard 1, when fireguard 1 is to fixed limited block 2 During compression, spring 3 is also compressed, and so as to provide opposite promotion, pushes fireguard 1 to battery terminal.
Preferably, there are two groups of elastic parts between fireguard 1 and fixed limited block 2.
It should be noted that the preferred embodiment of the application uses two groups of elastic parts, fireguard 1 and fixed limited block are realized 2 elastic connection, the movement locus of restriction fireguard 1 that can be more consolidated by two T-shaped leads 4 so that fireguard 1 Movement it is more flexible.
Preferably, the front end of fireguard 1 has inclined-plane 11.
It should be noted that the front end of fireguard 1 refers to, one end of oriented manipulation personnel and battery are put when in use The one end entered, in order to facilitate being put into for battery, this one end is especially designed to inclined-plane 11 by the application;The inclined-plane can be straight line Inclined-plane or curve slope facilitate battery to be put into, are not specifically limited herein as long as can play.
Disclosed herein as well is application of the protective device in the heat-sealing type terminal of LT series batteries freezes of the application.
The another side of the application also discloses a kind of pecten for the protective device for being equipped with the application, and protective device is pairs of It is installed on pecten, also, in each pair of protective device, the fireguard 1 of two protective devices and fixed limited block 2 are in mirror symmetry Arrangement.
It is appreciated that the protective device to freeze be it is pairs of be installed on pecten, also, in each pair of protective device, two The fireguard 1 of protective device and fixed limited block 2 are arranged in mirror symmetry, can just be pressed from both sides battery case and terminal strip group in this way Tightly.
Disclosed herein as well is application of the pecten in the heat-sealing type terminal of LT series batteries freezes of the application.
It should be noted that the protective device or pecten of the application are inherently directed to the heat-sealing type terminal of LT series batteries It freezes and designs.
The advantageous effect of the application is:
The protective device of the welding of lead-acid storage batteries terminal of the application, fireguard are connected with fixed limited block by elastic parts It connects, in use, fireguard and battery case and terminal strip can be ensured according to the actual size of battery case, automatic adjusting position Group is in close contact, and when freezing, plays the role of keeping off lead and poly- lead, avoids under lead liquid stream, scorch battery case.
