Description

Laser machine component

Technical field

The utility model technical field of laser processing, more specifically to a kind of laser processing component.

Background technology

Nickel lug in existing soft-package battery is not easy upper tin, needs the switching by aluminium, it is therefore desirable to first by aluminium pole Together with ear and nickel tab welding.In the prior art, the vertical view and sectional view point of aluminium pole ears and the weld assembly of nickel lug Not not as shown in Figure 1 and Figure 2.Nickel lug 10 is overlapped on aluminium pole ears 20.Used welding procedure is laser spot welding.Nickel pole The weld seam that 10 upper surface of ear is presented is several discrete dotted weld seams 40.Weldering meat residual schematic diagram is for example attached after stripped power test Shown in Fig. 3 and attached drawing 4, from attached drawing 3 and attached drawing 4 as can be seen that weldering meat residual is few, the peeling force and welding pulling force of weld assembly are all It is relatively low.

Therefore, a kind of laser processing component how is designed, which has stronger welding pulling force and peeling force, be Those skilled in the art's critical problem urgently to be resolved hurrily.

Utility model content

The purpose of this utility model is to provide a kind of laser processing component, the weld assembly have stronger welding pulling force with Peeling force.

In order to achieve the above objectives, the utility model provides following technical scheme：

A kind of laser processing component, including first and second, described first is overlapped on described second, described There is shaped weld, the fusion penetration of the shaped weld are extended on first clinch in described second.

Preferably, the shaped weld prolongs on first clinch along first width direction It stretches；The shaped weld is multiple, and multiple shaped welds are arranged along first length direction.

Preferably, in multiple shaped welds, from both ends to middle part, the fusion penetration of the shaped weld shortens successively.

Preferably, along first length direction, the fusion penetration of multiple shaped welds is deepened successively, Huo Zheyi Secondary shortening.

Preferably, the number of the shaped weld is four, and four shaped welds surround closed rectangle structure Weld seam.

It can be seen from the above technical proposal that in laser processing component in the present invention, first clinch It is upper that there are multiple shaped welds.The fusion penetration of shaped weld extends in second.Shaped weld and dotted weldering in the prior art Seam is compared, shaped weld than dotted weld seam have larger contact area, then shaped weld than dotted weld seam have it is larger Payload area, therefore, the weld assembly with shaped weld is with stronger welding pulling force and peeling force.

Specific implementation mode

The utility model provides a kind of laser processing component, which has stronger welding pulling force and stripping Power.

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are in the premise for not making creative work Lower obtained all other embodiment, shall fall within the protection scope of the present invention.

In a specific embodiment of the present invention, laser processing component includes first 1, second 2 and strip Weld seam 4.It is overlapped on second 2 for first 1, first 1 top for being located at second 2.The fusion penetration of shaped weld 4 extends to In two 2.In laser processing component in the present embodiment, there are multiple shaped welds 4 on first 1 clinch 3.Strip The fusion penetration of weld seam 4 extends in second 2.Compared with dotted weld seam in the prior art, shaped weld 4 compares a little shaped weld 4 Shape weld seam 40 has larger contact area, then shaped weld 4 has larger payload area than dotted weld seam 40, because This, the weld assembly with shaped weld 4 is with stronger welding pulling force and peeling force.

In a specific embodiment of the present invention, attached drawing 5 is please referred to, shaped weld 4 is on first 1 clinch 3 Extend along first 1 width direction.Shaped weld 4 is multiple, and multiple shaped welds 4 are along first 1 length direction Arrangement.I.e. when carrying out laser welding, laser scanner is in first 1 width direction, from first 1 side along straight line It is moved to the other side.Later, laser scanner is moved along first 1 length direction, carries out the weldering of second shaped weld 4 It connects.The ordered arrangement of multiple shaped welds 4 improves the welding pulling force and peeling force of weld assembly.

In a specific embodiment of the present invention, the number of shaped weld 4 is limited to be more than or equal to 3.Further, In multiple shaped welds 4, from both ends to middle part, the fusion penetration of shaped weld 4 shortens successively, please refers to attached drawing 6 and attached drawing 7.This The reason of sample is arranged is the stress that the stress at the both ends for the clinch for laser machining component is greater than middle part, therefore, will be located at two The fusion penetration setting of the shaped weld 4 at end wants deep.In addition, the fusion penetration of shaped weld 4 is different, then 4 bottom of shaped weld The stress point in portion would not be on the same horizontal plane, and such shaped weld 4 can bear larger welding pulling force and stripping Power.Attached drawing 8 and attached drawing 9 are please referred to, Fig. 8 is weldering meat residual schematic diagram after the stripped power test of laser processing component in Fig. 6；Figure 9 be the enlarged drawing of C in Fig. 8.From attached drawing 8 and attached drawing 9 as can be seen that the stripped power of laser processing component in the present embodiment is tested Weldering meat residual afterwards is more, and the peeling force for laser machining component is larger, and welding pulling force is larger.

In order to make the bottom stress point of shaped weld 4 not on the same horizontal plane, can bear to improving weld seam Peeling force and welding pulling force, can also use following scheme：Along first 1 length direction, the fusion penetration of shaped weld 4 is successively Deepen, or shortens successively.Please refer to attached drawing 11.

In a specific embodiment of the present invention, the number of shaped weld 4 is limited to 4.4 shaped welds 4 enclose At the weld seam 5 of closed rectangle structure, attached drawing 12 and attached drawing 13 are please referred to.During the welding process, laser scanner according to Rectangular trend sequentially completes the welding of four weld seams.

The above description of the disclosed embodiments enables professional and technical personnel in the field to realize or use this practicality new Type.Various modifications to these embodiments will be apparent to those skilled in the art, and determine herein The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein The widest range consistent with features of novelty.
