Abstract
The present invention relates to a battery sealed at the bottom of the battery, which comprises electrode groups 50, corresponding electrode terminals 30, a casing 40 with an upper partition plate, and a bottom plate 60. The electrode groups 50 are arranged in the casing 40 from the bottom up, and then the bottom plate 60 is covered on the lower end part of the casing 40 by pressing from the bottom up, and ultrasonic waves are used to carry out sealing welding, or a heat seal technology is used to carry out fusion welding, so that the bottom plate 60 and the lower end part of the casing 40 are integrated. The battery and a technology of the present invention have prominent advantages that because the casing of the accumulator is reasonably designed, space occupied by an original big cover is reduced, useful space of the electrode groups is enlarged, and battery capacity can be increased by 20%; because an ultrasonic welder bottom closing technology is simultaneously adopted, curing time is omitted, a production period is shortened, and production efficiency is raised by 1 time.
Description
Technical field the present invention relates to the secondary cell manufacturing process, relates in particular to the assembly technology of valve-regulated sealed lead-acid batteries.
The secondary cell of background technology prior art, valve-regulated sealed lead-acid batteries for example, its schematic construction as shown in Figure 1, label 1 ' indication cell body, 2 ' is big lid, 3 ' is loam cake, 4 ' is pole, 5 ' indication utmost point group.As seen from Figure 1, the whole volume of storage battery covers 2 ' greatly and occupies significant proportion.Small battery need be amplified under the situation that does not increase volume, improves performance, just is subjected to the restriction of big lid.In addition, in the assembling process of described storage battery, after the 5 ' assembling of utmost point group finishes, in the groove of normally packing into from top to bottom, with each utmost point group series connection welding.Because this is lower for plumbous fusing point, welding slag splashes down in the utmost point group easily, causes short circuit.
The summary of the invention the technical problem to be solved in the present invention is to avoid above-mentioned the deficiencies in the prior art part and proposes the assembly technology of a kind of battery from bottom sealing and the battery product that uses assembly technology of the present invention to produce.Product of the present invention is that the big lid 2 ' of battery and cell body 1 ' are merged the one injection casing 40 that is designed to have upper spacer 41, sees Fig. 2, and is from bottom opening.Described product is when assembling, and 50 assemblings of utmost point group finish, and with its described shell 40 of packing into from lower to upper, each pole 30 passes described upper spacer 41 back weldings.Because battery case 40 structures of the present invention are more reasonable, reduce former big lid 2 ' and take up room, thereby increase the useful space of holding battery utmost point group 50, increased battery capacity.
The technical problem to be solved in the present invention can be by solving by the following technical solutions: propose the assembly technology of a kind of battery from the bottom sealing, comprise the assembling of each utmost point group of operation A. itself; Especially also comprise process B. each utmost point group shell of packing into from lower to upper; C. gland lower shoe from lower to upper with ultrasonic wave soldering and sealing or use hot sealing process melting welding, makes lower shoe be integrated with the shell bottom; D. each pole after passing upper spacer welds each utmost point group series connection.
The technical problem to be solved in the present invention can also further solve by coming by the following technical solutions: design, make a kind of battery from the bottom sealing, comprise each utmost point group 50 and corresponding pole 30, and shell 40, especially, upper spacer 41 in described shell 40 and this shell is integrated, and this shell 40 is also at bottom opening, after described battery assembling finishes, in addition with lower shoe 60 from the bottom with described cell sealing.
Compare with prior art, the outstanding advantage of battery assembly technology of the present invention is: can make the housing designs of battery more reasonable, reduce former big lid and take up space, with the useful space of increase battery utmost point group, thereby increase battery capacity 20%.Owing to adopt ultrasonic bonding back cover technology, save curing time simultaneously, shorten the production cycle, and make production efficiency double.

G. fill in terminal sealing glue;
H. inject electrolyte;
I. charging.
Use the battery of the present invention from the assembly technology of bottom sealing, comprise each utmost point group 50 and corresponding pole 30, and shell 40, especially, upper spacer 41 in described shell 40 and this shell is integrated, and this shell 40 is also at bottom opening, after described battery assembling finishes, in addition with lower shoe 60 from the bottom with described cell sealing.
Embodiment 1, sees Fig. 3, and shell 40 bottom wall thickness δ attenuates, the periphery of lower shoe 60 are embedded in it or from the outside and surround, by ultrasonic wave soldering and sealing or use hot sealing process soldering and sealing.
Embodiment 2, see Fig. 4, and described lower shoe 60 inner face peripheries have continuous protuberant bar 62, with its from the bottom up gland be integrated with described bottom in shell 40 bottoms and by ultrasonic wave or after by hot sealing process melting welding.
The present invention also comprises bus-bar and line 10 and loam cake 20 from the battery of bottom sealing.
Described upper spacer 41 can become one in shell 40 in injection moulding, also can make separate part, be loaded in the shell 40, and upper spacer 41 is provided with pole hole 42.
