Description
Technical field
The utility model relates to the lead acid accumulator technical field, relates in particular to a kind of lead acid accumulator that improves battery performance, reduces material cost and cost of labor.
Background technology
Lead-acid accumulator is a kind of broad-spectrum battery product, and conventional now battery assembling manufacturing approach is that positive plate, negative plate and dividing plate are alternately placed, and based on the battery capacity size, a battery utmost point group is made up of 2-50 sheet positive plate and negative plate usually.A battery utmost point group rated voltage has only 2V, so 4V and above battery need 2 identical battery utmost point groups 1,2 as shown in Figure 1 to be in series.Discharge and recharge for the positive plate that makes same inside battery and negative plate all participate in, need positive plate and negative plate be adopted special frock, utilize the oxygen-acetylene gas welding to connect.
Particularly; Two burning bar of leads at high temperature are melted in the lug 13 of positive plate and negative plate respectively; Form positive plate bus-bar and negative plate bus-bar 12 respectively, said positive plate bus-bar, negative plate bus-bar 12 with each positive plate, and the charging and discharging currents of each negative plate pool together.With the example that is welded as of positive plate and positive plate bus-bar 12, in mould, put into first of a prior cast molding and connect pole 11, the positive plate lug is connected pole with first utilize acetylene welding at high temperature, weld together with a burning bar of lead.The first battery utmost point group 1 that the welding back forms connects pole 3 through second in the second battery utmost point group and links to each other with the second battery utmost point group 2, thereby forms battery pack.
The conventional structure composition of above-mentioned lead acid accumulator and the shortcoming of assembly method are following:
1.. operation is many, and is many with manual work, and efficient is low: the assembly operation of conventional lead acid accumulator is following, a plurality of single battery utmost point groups and specific welding assambly is assembled together; Put into the connection pole again; Freeze; Remove frock; Take out utmost point group; The utmost point is assembled in the battery case.
2.. have hidden danger of quality: because positive and negative electrode plate ear is shorter, the surface is prone to oxidation, is prone to pollute, and is not easy welding; Because the frock distortion cooperates not tight, plumbous at the welding hourglass easily; Because under 2500-3000 ℃ work high temperature, lead can melt very short time, flame moves soon when therefore welding simultaneously.Owing to above reason, very easily cause between lug and the bus-bar, connect between pole and the bus-bar and have rosin joint and dry joint phenomenon, ratio is up to more than 1%.Because positive and negative pole plate does not weld, can not participate in battery charging and discharging, thereby cause utmost point cell set capacity defective, the life-span is short; Connect pole and under vibratory impulse, break off, battery opens circuit, and can't use and scraps.
3.. high material consumption, the battery cost is high: because bus-bar is all used terne metal with the connection pole, consume a large amount of slicker solders, this part material cost accounts for the battery cost more than 3%.
4.. owing to adopt bus-bar, battery pole plates can not be too high, thereby battery capacity can not be improved on existing basis; The internal resistance of cell is high, and heavy-current discharge performance is poor.
To sum up, change the assembly method of existing lead acid accumulator, improve battery performance, reduce material cost and cost of labor, will become a very necessary job.
The utility model content
The purpose of the utility model is to provide a kind of lead acid accumulator that improves battery performance, reduces material cost and cost of labor.
Be to realize above-mentioned purpose, said lead acid accumulator comprises a plurality of battery utmost point groups, each battery utmost point group comprise arranged in a crossed manner and between be separated with the positive plate and the negative plate of dividing plate; The characteristics of this lead acid accumulator are that the length of positive plate lug and negative plate lug increases by 20% at least in each said battery utmost point group; And all positive plate lugs of each said battery utmost point group and all negative plate lugs of adjacent cell utmost point group directly weld together; Positive plate lug and the idle negative plate lug of free time that is positioned at two battery utmost point groups at head and the tail edge becomes the positive binding post and the negative binding post of said lead acid accumulator respectively.
The beneficial effect of the utility model is; Said lead acid accumulator is only accomplished positive plate lug or the welding of negative plate lug and the connection between the adjacent two single battery utmost point groups between the single battery utmost point group through a step; Make manufacturing process reduce 60%; 10 operations by original are reduced to 4 operations, save human cost, have improved production efficiency; In addition, reduce material consumption, saved bus-bar and the material that connects pole particularly; Battery performance and reliability have been improved.
Description of drawings
Fig. 1 shows the structural representation of the lead acid accumulator that comprises two battery utmost point groups under the conventional manufacturing approach.
Fig. 2 shows the structural representation of the lead acid accumulator that comprises 2 battery utmost point groups.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 2 shows the structural representation of the lead acid accumulator that comprises 2 battery utmost point groups; As shown in Figure 2; Said lead acid accumulator comprises 2 battery utmost point groups; The first battery utmost point group 1 and the second battery utmost point group 2,1,2 groups of first, second battery utmost points include arranged in a crossed manner and between be separated with the positive plate and the negative plate of dividing plate, said dividing plate preferably has glass fiber.The length of positive plate lug and negative plate lug increases by 20% at least in first, second battery utmost point group 1,2, so that first, second battery utmost point group 1,2 is put into battery case back positive plate lug and negative plate lug upper end is higher than battery case 6 to 7mm.Wherein, all negative plate lugs of all the positive plate lugs of the first battery utmost point group 1 and the second battery utmost point group do not use bus-bar, directly weld together; All positive plate lugs of the first battery utmost point group 1 and the second battery utmost point group, 2 all idle negative plate lugs become the positive binding post and the negative binding post of said lead acid accumulator respectively.
The assembly method that is configured to the lead acid accumulator of 6V4Ah may further comprise the steps:
Step 1: the length of the positive plate lug of each battery utmost point group and negative plate lug added by 12mm grow to 23mm;
Step 2: the battery utmost point that is 2V with 3 rated voltages is assembled in the battery case 4; And,
Step 3: utilize a special frock, all the negative plate lugs with all the positive plate lugs of a battery utmost point group and adjacent battery utmost point group do not use bus-bar, directly weld together with acetylene; Positive plate lug and the idle negative plate lug of free time that is positioned at two battery utmost point groups at head and the tail edge becomes the positive binding post and the negative binding post of said lead acid accumulator respectively.
By on can know that said lead acid accumulator is only accomplished positive plate lug or the welding of negative plate lug and the connection between the adjacent two single battery utmost point groups between the single battery utmost point group through a step.Through the test, battery each item performance has all surpassed original battery, capacity has improved 15%, in reduced by 20%, cost savings more than 5%.
Being merely the utility model preferred embodiment in sum, is not the practical range that is used for limiting the utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to the technological category of the utility model.
