Description
Technical field
The invention belongs to electronic product machining technical fields, and in particular to a kind of grip slipper of electronic product laser welding.
Background technique
Electronic product is in processing and manufacturing process, and electronic component is frequently necessary to carry out spot welding, and laser welds with one heart
It is that welding effect is best in current welding field, the best welder equipment of production efficiency, the concentric welding equipment of laser mainly uses
Processed product position immobilizes, and the mode that laser emission element is rotated on the rotating platform realizes concentric weldering
It connects, this welding equipment advantage most prominent compared to laser welding apparatus common in the market is: after the completion of a Product jointing,
Not needing to shut down waits product to stop rotating, then clamping starting rotation again again.It is complete that Product jointing has been saved in whole process
Cheng Houcong rotates to the time of stopping, therefore production efficiency can be greatly enhanced.
It needs to be protected using protective gas during laser welding, laser welding protective gas mainly has three
Kind: helium not easily ionizable (ionizing energy is higher) can allow laser to pass through, and beam energy goes directly workpiece table in the clear
Face uses most effective protective gas when this is laser welding, but price is somewhat expensive；Argon gas is relatively cheap, and density is larger, so
Protecting effect is preferable.But it is ionized vulnerable to high-temperature metal plasma, is as a result shielded segment beam directive workpiece, is reduced weldering
The effective laser power connect also damages speed of welding and fusion penetration.The weldment surface protected using argon gas is than using helium to protect
When, comes smooth；Nitrogen is generally the least expensive as protective gas, but it is stainless steel welded to certain types when and be not suitable for, mainly due to
Problem in terms of metallurgy such as absorbs, and generates stomata in overlap sometimes.
Several each have their own advantages of protective gas, but in use, protective gas is all for laser welding apparatus at present
It is to follow laser emission element together and reach workpiece to be processed surface by jet hole with certain pressure injection to be protected,
But since protective gas can spray always during welding, and laser emission element in process with it is to be processed
Workpiece has certain distance, and the protective gas projected can cause certain perturbation action to workpiece surface molten metal, lead
Cause face of weld Forming Quality poor.
Summary of the invention
The protective gas that the present invention welds injection in order to solve laser with one heart can blow molten metal and cause surface at
The ropy problem of type, and a kind of grip slipper of electronic product laser welding is provided, guarantor can be released by grip slipper automatically
