Specific implementation mode
It is described in further detail below by specific embodiment and in conjunction with attached drawing to the application.
As illustrated in figures 1 and 8, the embodiment of the present application provides a kind of laser welding apparatus comprising mounting bracket 1, laser
Plumb joint 2 and workpiece positioning clamp 3, laser welding head 2 and workpiece positioning clamp 3 are installed on mounting bracket 1, work piece positioning
Tool 3 can carry out positioning clamping to workpiece to be welded, to prevent the position of said workpiece in the welding process from changing, and
Influence welding precision.It, can be by laser welding head 2 to work to be welded after workpiece positioning clamp 3 clamps said workpiece
Part carries out welding job.Wherein, it can be provided with welding window 332 on workpiece positioning clamp 3, so that laser welding head 2 is penetrated
The laser gone out can pass through welding window 332, and treat welding workpiece and carry out welding job, be generated in welding process in order to prevent
Welding slag be adhered on welding window 332, air inlet 331 and air outlet 333 are also provided on workpiece positioning clamp 3, into
Air port 331 is connected to air outlet 333 by welding window 332, air outlet 333 can external pumping dirt equipment, as monomer take out dirt set
Standby or workshop, which is concentrated, takes out dirt system etc., and the welding slag generated in welding process and flue dust are taken away.Specifically, mounting bracket 1 can be with
For metal structure frame, laser welding head 2 can be the laser-beam welding machine of setup parameter, or galvanometer bonding machine etc., it can
It, can also be directly by welding by laser welding head laser welding head 2 to be connected on mounting bracket 1 by fastener
2 are fixedly connected on mounting bracket 1；In workpiece positioning clamp 3, a part is used to support workpiece to be welded, and another part is set to
The top of workpiece to be welded, to during aforementioned two parts are close to each other and separate, reach clamping or release is to be welded
The purpose of workpiece.
It is above-mentioned it is found that workpiece, which can pass through workpiece positioning clamp 3, realizes that laser and laser are projected in positioning, laser welding head 2
It is contacted with workpiece across the welding window 332 of workpiece positioning clamp 3, to carry out welding job.Welding window 332 and air inlet
331 are connected to air outlet 333；Meanwhile it by the air outlet 333 being connected to pumping dirt equipment, can will be produced in welding process
Raw flue dust and welding slag is taken away, to prevent welding slag to be adhered on the hole wall of welding window 332, with the work in welding secondary cell
When part, it is ensured that secondary cell has higher security performance.
In order to reduce the probability that welding slag enters in welding window 332, it is preferable that as shown in Figure 3 and Figure 4, weldering can be arranged
The cross-sectional area of the part in window 332 close to workpiece is connect, the cross-sectional area close to the part of laser welding head 2 is less than,
After being arranged in this way, by that, close to the reduced cross-sectional area of the oral area of workpiece, will can be passed through in guarantee laser in welding window
While welding window 332 realizes focusing, the probability that welding slag enters welding window 332 can also be reduced；Even if in addition, still there is portion
Divide welding slag to enter and be adhered on the hole wall of welding window 332, the hole wall for the welding window 332 being obliquely installed may be welding slag
Certain support force is provided, prevents it from falling in secondary cell.
For the working efficiency of improving laser welding equipment, optionally, welding window 332 can be provided with it is multiple, it is multiple
Welding window 332 can be connected to air inlet 331 and air outlet 333, and during welding workpiece, laser welding head 2 can
To be converted between different welding windows 332, after the completion of the workpiece welding at a welding window 332, laser welding head 2 can
To change position, to continue welding job at another welding window 332, in this process, it is located at upper one and welds
Workpiece at window 332 can be removed, and change it is another need the workpiece that welds, can make in this way laser welding head 2 not between
Disconnected work achievees the purpose that promote welding efficiency.Specifically, welding window 332 can be arranged there are two, three or more
