Description
Technical field
The utility model is related to technical field of semiconductor encapsulation more particularly to a kind of enhanced type automobile battery unit to weld
Aluminum steel chopper.
Background technology
When automobile batteries unit splicing is at battery pack, the connection same polarity of each unit is welded to same pole using aluminum steel
On the frame plate of property.Since the main tool of aluminum steel welding is chopper, by the way of ultrasonic wire bonding, aluminum steel is welded on frame
Reliability on frame plate, fastness are largely dependent on the way of contact of chopper and aluminum steel.
The way of contact of existing chopper and aluminum steel, contact surface is smaller, the problem of easy ting produce rosin joint, desoldering.
Therefore, the prior art is defective, needs to improve.
Utility model content
Technical problem to be solved in the utility model is：A kind of increase aluminum steel forced area is provided, keeps bonding wire more secured
Reliably, the enhanced type automobile battery unit weldering aluminum steel chopper of quality of welding spot is promoted.
The technical solution of the utility model is as follows：A kind of enhanced type automobile battery unit weldering aluminum steel chopper, including chopper
Main body and chopper cutter head, the chopper cutter head include a V-groove body, also, several raised terrace with edges of setting in the V-groove body；
Aluminum steel fixed placement contacts fixation with the upper surface of each raised terrace with edge respectively in the V-groove body；Wherein, the V-groove
The groove depth of body is 0.20 ± 0.005mm, and slot top width is 0.440 ± 0.005mm.
Applied to above-mentioned technical proposal, the enhanced type automobile battery unit welds in aluminum steel chopper, each protrusion terrace with edge
Height be 0.05 ± 0.005mm.
Applied to above-mentioned technical proposal, the enhanced type automobile battery unit welds in aluminum steel chopper, is provided with 3 shapes
The identical raised terrace with edge of shape size, also, the cross-sectional width of each raised terrace with edge is identical as the groove width size of V-groove body.
Using the above scheme, the utility model is by being arranged V-groove body, also, several raised ribs of setting in V-groove body
Platform；Aluminum steel fixed placement contacts fixation with the upper surface of each raised terrace with edge respectively in the V-groove body；Chopper and aluminum steel
Relative contact is larger, it is not easy to rosin joint, desoldering are led to the problem of, while increasing aluminum steel forced area, and each protrusion terrace with edge pair
Aluminum steel can also play the role of fixed point it is fixed, during use to aluminum steel, have the function of centainly prevent displacement, from
And bonding wire can be made more solid and reliable, promote quality of welding spot.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the enlarged drawing of part A in Fig. 1；
Fig. 3 is the right view of Fig. 2.
Specific implementation mode
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Present embodiments provide a kind of enhanced type automobile battery unit weldering aluminum steel chopper, as shown in Figs. 1-3, enhanced vapour
It includes chopper main body 10 and chopper cutter head 20 that vehicle battery unit, which welds aluminum steel chopper, wherein the chopper cutter head 20 includes a V-type
Groove body 21, also, several raised terrace with edges 22 are set in the V-groove body 21；Wherein it is possible to which multiple raised terrace with edges 221, convex are arranged
Play terrace with edge 222, raised terrace with edge 223 etc., aluminum steel fixed placement in the V-groove body 21, and respectively with each raised terrace with edge 221,
Raised terrace with edge 222, raised terrace with edge 223 upper surface contact fixation respectively；In this way, aluminum steel in the V-groove body 21 with each raised rib
Platform contacts fixation respectively, can not only increase the contact area of aluminum steel and V-groove body, also, each raised terrace with edge may be used also to aluminum steel
With play the role of fixed point it is fixed, during use to aluminum steel, have the function of centainly prevent displacement, so as to so that
Bonding wire is more solid and reliable, promotes quality of welding spot.
Wherein, the groove depth of the V-groove body is 0.20 ± 0.005mm, and slot top width is 0.440 ± 0.005mm.
The height of each protrusion terrace with edge is 0.05 ± 0.005mm.In this way, by the way that size is arranged, so that it is more bonded with aluminum steel contact, make
It is more preferable with effect.
Alternatively, the identical raised terrace with edge 221 of 3 shape sizes, raised terrace with edge 222, raised terrace with edge 223 can be provided with；
Also, the cross-sectional width of each protrusion terrace with edge is identical as the groove width size of V-groove body, i.e., a raised terrace with edge is along V-groove body
Side setting, and fill up the trench bottom of entire V-groove body, increase the contact area of aluminum steel and raised terrace with edge to greatest extent,
Effect is more preferable.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
All any modification, equivalent and improvement etc., should be included in the guarantor of the utility model made by within novel spirit and principle
Within the scope of shield.
