Abstract
The utility model relates to a utmost point ear and draw piece ultrasonic bonding positioning fixture, characterized by: the welding seat is fixed on the supporting body, the left side wall and the right side wall of the welding seat are fixedly connected with the positioning blocks respectively, and the guide piece is arranged on the upper surface of the welding seat between the two positioning blocks. Has the advantages that: the support body and the positioning block on the support body are used for realizing accurate positioning of the welding seat, the lead piece and the lug; the lower lug is protected by using a lug protection belt, so that the lug is prevented from being damaged due to overlarge pressing force of a welding head during ultrasonic welding; the whole structure is matched with the ultrasonic welding equipment, the structure is simple, and the operation is convenient.
Description
Technical field
The utility model belongs to the lithium battery Clamp for welding, relates in particular to a kind of lug and leader ultrasonic bonding positioning fixture that is used on the aluminum-shell battery transfer matic.
Background technology
At present; Lithium ion battery have voltage height, specific energy high, recycle often, advantage such as memory time is long; Not only on portable electric appts, be used widely; And to be widely used in big-and-middle-sized electrical equipment aspect, especially electrokinetic cells such as electric automobile, electric bicycle and electric tool be the present main direction of each macrocell producer development.In the production of batteries of electric automobile; Battery pole ear; Being connected of leader and pole is a ring of most critical, and the connected mode of best solution lug and leader is exactly ultrasonic bonding, and ultrasonic bonding can be through the fusion between two or three parts of high frequency sound wave realization of thrust between soldering tip and the weldering seat and release; Greatest problem in producing at present is that weld strength is not enough; The ultrasonic bonding reliability is just poor, traces it to its cause that it is unreliable to be to locate, the location structure problem of the ultrasonic bonding that needs to be resolved hurrily in the production procedure.
The utility model content
The utility model is in order to overcome deficiency of the prior art, a kind of easy to operate, dependable performance is provided, is used for lug and leader ultrasonic bonding positioning fixture on the aluminum-shell battery transfer matic.
The utility model is for realizing above-mentioned purpose; Realize through following technical scheme; A kind of lug and leader ultrasonic bonding positioning fixture is characterized in that: comprise supporter, weldering seat, locating piece and leader, said weldering seat is fixed on the supporter; Said weldering seat left and right sides wall is affixed locating piece respectively, and said leader places on two weldering seat upper surfaces between the locating piece.
Said supporter bottom is provided with the dovetail that cooperates with ultrasonic welding system.
Said locating piece inside upper part is provided with the groove of opening suitable for reading, places the lug boundary belt in the said groove.
Two are parallel to each other and vertically connect about the said leader, and its lateral cross section shape is stairstepping.
Beneficial effect: use supporter and top locating piece to realize weldering seat, the accurate location of leader and lug; Use the following lug of lug boundary belt protection, when preventing ultra-sonic welded, because of the soldering tip thrust is crossed the havoc lug; Overall structure matches with ultrasonic welding system, and is simple in structure, easy to operate.

Fig. 3 is that battery utmost point group and lug are positioned over the structural representation on the leader;
Fig. 4 is positioned over the structural representation on the battery pole ear with the lug boundary belt.
Among the figure: 1, supporter, 1-1, dovetail, 2, weldering seat, 3, leader, 4, battery utmost point group, 5, lug boundary belt 6, locating piece, 6-1, groove.
The specific embodiment
Below in conjunction with preferred embodiment, details are as follows to the specific embodiment that provides according to the utility model: see accompanying drawing for details, a kind of lug and leader ultrasonic bonding positioning fixture; Comprise supporter 1, weldering seat 2, locating piece 6 and leader 3; Said weldering seat is fixed on the supporter, and said weldering seat left and right sides wall is affixed locating piece respectively, and said leader places on two weldering seat upper surfaces between the locating piece; Two are parallel to each other and vertically connect about the said leader, and its lateral cross section shape is stairstepping.Said supporter bottom is provided with the dovetail 1-1 that cooperates with ultrasonic welding system.Said locating piece inside upper part is provided with the groove 6-1 that opens suitable for reading, places lug boundary belt 5 in the said groove.
Install: the weldering seat is fixed in the supporter through the screw of 6 M5 and the screw of 2 M8, and positioning fixture cooperates with ultrasonic bonding machine through the dovetail 1-1 of supporter bottom.During work, earlier leader is placed on the weldering seat, the lug with battery utmost point group 4 partly is placed on the leader then, at last the lug boundary belt is placed on above the lug; Leader; Lug and lug boundary belt are all realized accurately location by the locating piece of both sides on operating desk; Leader and lug boundary belt all guarantee enough flatnesses man-hour reducing gap each other adding, and total is accomplished ultrasonic bonding under the effect of soldering tip weldering seat.
The above only is the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
