Abstract
The utility model discloses a positioning clamp for spot welding of pole tabs of a lithium ion battery and is characterized in that the positioning clamp comprises a clamp body (1), the clamp body (1) takes the shape of a strip, a battery core clamp slot (1a) is formed longitudinally on one surface of the clamp body (1), and an anode tab positioning groove (1b) and a cathode tab positioning groove (1c) are longitudinally formed side by side on the other surface of the clamp body (1). The positioning clamp has the characteristics of simple structure, unique design and convenience in installation, and accurately ensures the welding point positions of the pole tabs, the distance between the pole tabs and the perpendicularities of the pole tabs relative to the battery core, and greatly increases the production efficiency.
Description
Technical field
The utility model relates to a kind of positioning fixture that belongs to, and relates in particular to a kind of being used for battery pole ear is welded on spot welding positioning fixture on the battery.
Background technology
Lithium ion battery is made up of battery and the positive and negative battery pole ear that is fixed on the battery.Positive and negative battery pole ear all is fixed by welding on the battery.During square lithium ion battery lug spot welding at present, by manually lug being contacted and apply certain pressure with aluminium foil or Copper Foil, put into the enterprising spot welding of wave welding head of ultrasonic wave then, owing to be manual operation all, can't accurately guarantee the perpendicularity of lug bond pad locations, lug spacing, lug and battery, production efficiency is lower simultaneously.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of lithium ion cell polar ear spot welding positioning fixture that electrode ear and battery is positioned welding.
The technical solution of the utility model is as follows: a kind of lithium ion cell polar ear spot welding positioning fixture, its key is: comprise chuck body, described chuck body is that bar shaped is tabular, this chuck body simultaneously is vertically arranged with electric core draw-in groove, and described chuck body another side is vertically arranged with anode ear locating slot and negative electrode lug locating slot side by side.According to the groove position and the groove width of electric core width, lug width, both positive and negative polarity ear space designs fix, insert electric core in the electric core draw-in groove before the spot welding, lug inserts in the lug locating slot in the practice, make lug and kept relative fixed by the some weldment.The point postwelding guarantees that the perpendicularity of lug bond pad locations, lug spacing, lug and battery reaches requirement.
Above-mentioned anode ear locating slot and negative electrode lug locating slot are all by chuck body one end setting.Be convenient to battery and a lug part is stretched out outside the chuck body, carry out electric welding.
Above-mentioned chuck body is outward extended with dividing plate by anode ear locating slot and negative electrode lug locating slot one end.Dividing plate is extremely thin, and battery to be welded and lug are separated the maintenance certain clearance, can not burn the battery internal structure during welding.
Beneficial effect: the utlity model has simple in structure, design is unique easy for installation, has accurately guaranteed the perpendicularity of lug bond pad locations, lug spacing, lug and battery, the while has been improved production efficiency greatly.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, a kind of lithium ion cell polar ear spot welding positioning fixture, comprise chuck body 1, described chuck body 1 is tabular for bar shaped, this chuck body 1 one side is vertically arranged with electric core draw-in groove 1a, and described chuck body 1 another side is vertically arranged with anode ear locating slot 1b and negative electrode lug locating slot 1c side by side.Described anode ear locating slot 1b and negative electrode lug locating slot 1c are all by chuck body 1 one end settings.Described chuck body 1 is outward extended with dividing plate 2 by anode ear locating slot 1b and negative electrode lug locating slot 1c one end.
Although below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite of the utility model aim and claim; can make multiple similar expression, such conversion all falls within the protection domain of the present utility model.
