Abstract
A locating device for tab welding is used for solving the problem that the distance between a tab rubber block and the edge of a current collector is not easy to be located in the procedure of welding positive and negative tabs of lithium ion batteries on the current collector. The locating device comprises an ultrasonic welder soldering station. After improvement, the outer side of the soldering station is provided with a tab welding formwork; the thickness L of the formwork is the location dimension; and the location dimension is matched with the technology dimension from a welded tab rubber block to the edge of the current collector. The locating device is simple in structure, easy for implementation and convenient for operation, and can be provided with formworks to match with tabs of different specifications to meet product requirements. By welding the positive and negative tabs on the current collector, the locating device can not only ensure that the distance between the tab rubber block and the edge of the current collector totally meets technological requirements, but also greatly increase the welding speed of operating staff.
Description
Technical field
The utility model relates to a kind of battery manufacturing technology, particularly lithium battery pole ear apparatus for welding and positioning, belongs to the battery technology field.
Background technology
Polymer Li-ion battery operating voltage height (3.6V, be cadmium-nickel, hydrogen-nickel-based battery three times), volume little (littler by 30% than hydrogen-nickel-based battery), light weight (lighter by 50% than hydrogen-nickel-based battery), specific energy height (be 2～3 times of cadmium-nickel-based battery, 1～2 times of hydrogen-nickel-based battery), memory-less effect, pollution-free, self discharge is little, have extended cycle life, and is the desirable energy of 21 century development.Polymer Li-ion battery is widely used in mobile phone, mobile DVD, NOTEBOOK, video camera, digital camera, digital code camera, notebook computer, electric motor car, portable type global position system etc.The polymer Li-ion battery welding of positive and negative lug in process of production is one important procedure, and the task of this procedure is that positive and negative lug is welded to respectively on aluminium foil and the Copper Foil collector, to draw electric current.Owing to relate to follow-up closedtop operation, both positive and negative polarity lug blob of viscose, aluminum plastic film need be bonded together by heating, pressurization respectively.The limited length on lug blob of viscose length and collector closedtop limit, require the encapsulation of lug blob of viscose to expose size simultaneously and will satisfy technological requirement, this just require lug when welding with collector and the distance at collector edge don't fail to satisfy certain dimensional requirement, to guarantee that lug blob of viscose and aluminum plastic film closedtop limit have bigger coincidence area and be convenient to encapsulation, lug glue encapsulation simultaneously exposes size and also need satisfy technological requirement.At present in the production process of reality, the distance at lug blob of viscose and collector edge is to rely on operator's experience to judge, mismachining tolerance is bigger, different operative employee's actual welding distances is also different, in earlier stage need train when especially new hand welds, otherwise can cause more substandard product, follow-up closedtop encapsulation is brought adverse influence; In addition, the lug closedtop exposes the problem that technological requirement also can appear not meeting in size, and battery need be done over again and be welded again when serious, has not only increased the product expense and has decreased, and has also reduced production efficiency.
The utility model content
The utility model is used to overcome the defective of prior art and a kind of simple in structure, lug apparatus for welding and positioning of being convenient to operate is provided.
The alleged problem of the utility model solves with following technical proposals:
A kind of lug apparatus for welding and positioning, comprise the supersonic welder welding stage in the formation, its special feature is: the described welding stage outside is provided with lug welding template, and described template thickness L is a location dimension, and this location dimension and soldered lug blob of viscose are complementary apart from the process at collector edge.
Above-mentioned cylindrical lithium battery air tightness checkout gear, the top of described template is provided with the lug groove, and the lug groove is " recessed " font, and its groove width B and soldered lug width are complementary.
Above-mentioned cylindrical lithium battery air tightness checkout gear, the lug well width B of described template is respectively 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, and the thickness L that every kind of width is corresponding respectively is two kinds of 2mm and 1mm.
The utility model is in the positive and negative lug welding of the existing polymer Li-ion battery collector operation, the distance at lug blob of viscose and collector edge is difficult for orientation problem frock is improved, designed a kind of thickness and above-mentioned orientation distance coupling, and the template that has the lug groove, this template is adhered to the welding stage outside, the thickness of this template is location dimension during welding, only needs the lug blob of viscose is abutted against the distance that the template place just can guarantee lug blob of viscose and collector edge accurately.This apparatus structure is simple, is easy to realize, can the demand that satisfy production with the template of its coupling be installed according to the lug of different size.Adopt the utility model on collector, to weld positive and negative lug, not only can guarantee that the distance at lug blob of viscose and collector edge satisfies technological requirement fully, and can improve operating personnel's speed of welding greatly.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the formwork structure schematic diagram;
Fig. 3 is the left view of Fig. 2;
Fig. 4 is lug, lug blob of viscose schematic diagram.
Each label implication is as follows in the accompanying drawing: 1. supersonic welder welding stage; 2. collector; 3. template; 3-1. lug groove; 4. lug; 5. lug blob of viscose.
The specific embodiment
Referring to Fig. 1, Fig. 5, the welding stage 1 that comprises supersonic welder during the utility model constitutes, soldered collector 2 is layered on the welding stage, the bonding lug welding template 3 in the outside of welding stage 1, the thickness L of this template is a location dimension, and this location dimension and soldered lug blob of viscose 5 are complementary apart from the process at collector 2 edges.
Referring to Fig. 1-3, the top of described template 3 is provided with lug groove 3-1, and the lug groove is " recessed " font, lug 4 places in the lug groove during welding, spacing so that lug is formed, lug blob of viscose 5 abuts against the outside of template 3, and the width B of lug groove and soldered lug width are complementary.
During the actual use of the utility model, according to lug specification difference, make a series of templates, the lug well width B of template is respectively 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, the template thickness L that every kind of width is corresponding respectively is two kinds of 2mm and 1mm, and lug groove height H is advisable for the 2-3 millimeter.Selecting suitable template to be bonded in the supersonic welder welding stage outside during welding gets final product.
