Detailed description of the invention
More fully the present invention is described with reference to the accompanying drawings hereinafter, exemplary embodiment of the present invention shown in the drawings.As the skilled person will recognize, when all not departing from the spirit or scope of the present invention, described embodiment can be revised in a variety of ways.Accompanying drawing is considered to illustrative and not restrictive in essence with being described in.Label identical in whole description indicates identical element.
Fig. 1 is the perspective view of the laser welding apparatus according to the first exemplary embodiment of the present invention, and Fig. 2 is the sectional view intercepted along the II-II line in Fig. 1.See figures.1.and.2, comprise gas according to the laser welding apparatus 100 of the first exemplary embodiment and spray block 10, exhaust block 20, laser safety glass 30 and laser head 40.
Gas sprays the welding portion that block 10 holds welding object (such as, the housing 51 of rechargeable battery and cover plate 52), and to welding portion injecting protective gas (such as, N
2) to protect welding portion, thus the oxidation of welding portion can be prevented.
Exhaust block 20 is connected to gas and sprays the upside of block 10 to act on suction in side, thus the cigarette produced at welding portion and the inert gas of protection welding portion is discharged to the opposite side of exhaust block 20.
Laser safety glass 30 is fixedly secured to the upside of exhaust block 20 by fixed head 31 and clamp structure 32, and covers the upside of being sprayed the welding portion that block 10 and exhaust block 20 hold by gas, thus can carry out laser weld by scan method.Laser safety glass 30 has not by durability that laser beam damages.
The upside that laser head 40 is arranged on laser safety glass 30 regularly keeps predetermined distance with laser safety glass 30 simultaneously, and controls scope (not shown), makes it possible to make laser beam irradiation to welding portion by scan method.
The laser beam irradiated from laser head 40 is transferred to laser safety glass 30, and sprays the inside arrival welding portion of block 10 and exhaust block 20 through gas.For this purpose, gas sprays block 10 and forms the first space 11, and exhaust block 20 forms second space 21.
The first space 11 that the second space 21 of exhaust block 20 and gas spray block 10 is connected to each other on the direction of illumination of laser beam, thus holds welding portion and form welding space.Therefore, beam transmission to laser safety glass 30, and sequentially passes second space 21 and the first space 11.In addition, the plane (xy plane) of the first space 11 and second space 21 is formed than the scanning area field width of the laser beam irradiated from laser head 40, thus is not interfered for the scanning of laser beam to welding portion of welding.
Fig. 3 is the sectional view of the gas injection block being applied to Fig. 1.With reference to Fig. 3, gas sprays block 10 and comprises the room 12 of the outer periphery being formed in the first space 11, the gas feed 13 being connected to the outside of room 12 and the spray-hole 14 be connected with the first space 11 room 12.
Gas feed 13 is connected to external inert gas feeding unit (not shown), thus is fed to gas injection block 10 by inert gas from outside.Therefore, the inert gas flowing to gas feed 13 is filled in gas and sprays in the room 12 of block 10, is then ejected into the first space 11 by spray-hole 14, thus protection welding portion.
Room 12 absorbs the expulsion pressure flowing to the inert gas of gas feed 13, thus can by spray-hole 14 with uniform pressure injection inert gas.Therefore, welding portion is stably protected by inert gas, thus can prevent the oxidation of welding portion.
Such as, room 12 can be formed according to the outside in the first space 11, and round-shaped formation is sentenced in the longitudinal cross-section (yz cross section) can spraying block 10 at gas.That is, according to the arranged outside in the first space 11, there is round-shaped room 12.
Gas feed 13 is formed centrally in the diametric(al) of room 12, and the extension of the center line of gas feed 13 forms diagonal angle thus on yz cross section.That is, with reference to Fig. 3, from left upper end to bottom righthand side, gas feed 13 is formed.Therefore, inert gas to flow in room 12 in the heart by gas feed 13, thus the extended line of the center line of gas feed 13 in inside, room 12 forms the fluid stream of symmetrical structure.
In addition, multiple gas feed 13 (with reference to Fig. 1 and Fig. 4) can be formed at predetermined intervals according to the outside in the first space 11.Multiple gas feed 13 is at the whole region supplying inert gas equably of the outer periphery of the room 12 corresponding with the outside in the first space 11.

Such as, rib 25 comprise with predetermined space formed the first spray-hole 241 first rib 251, formed with predetermined space the second spray-hole 242 second rib 252 and form the 3rd rib 253 of the 3rd spray-hole 243 with predetermined space.
First rib 251, second rib 252 and the 3rd rib 253 contribute to the processing of the first spray-hole 241, second spray-hole 242 and the 3rd spray-hole 243, and improve the mechanical strength that gas sprays block 210, but the injection of injected inert gas is partially blocked.
Therefore; first spray-hole 241, second spray-hole 242 and the 3rd spray-hole 243 or first rib 251, second rib 252 and the 3rd rib 253 are alternately arranged according to the outer periphery in the first space 11, thus gas sprays the protective value deterioration of the welding portion that block 210 can prevent the part obstructs due to inert gas from causing.
Fig. 7 is the top view of inert gas jeting area in the laser welding apparatus according to the third exemplary embodiment of the present invention.With reference to Fig. 7, the spray-hole 34 that gas sprays block 310 can be formed as separated circular port according to the outer periphery in the first space 11.
Round-shaped spray-hole 34 is formed in the position corresponding with the first spray-hole 141, second spray-hole 142 of the first exemplary embodiment and the 3rd spray-hole 143 (such as, formation as shown three lines) place, and alternately can arrange according to the outer periphery in the first space 11.
Fig. 8 is the sectional view of the laser welding apparatus 400 according to the fourth exemplary embodiment of the present invention.With reference to Fig. 8, by utilizing barrier structure 26 to stop, inlet manifold 23 forms exhaust outlet 22 along the direction (y-axis direction) crossing with the laser beam irradiation direction (z-axis direction) of the second space 21 that laser beam passes to exhaust block 420.
Compared with the first exemplary embodiment, the 4th exemplary embodiment also comprises barrier structure 26 at inlet manifold 23 place, but exhaust block can only comprise exhaust outlet and not comprise inlet manifold and barrier structure (not shown).
Exhaust outlet 22 is connected by pipeline 221, thus the inert gas flow formed under the effect acting on the suction on pipeline 221 from the first space 11 to second space 21 and external air flow.Here, external air flow is formed between gas injection block 10 and welding portion.Cigarette and inert gas can be discharged to exhaust outlet 22 along with extraneous air.
Fig. 9 is the sectional view of the laser welding apparatus 500 according to the fifth exemplary embodiment of the present invention.With reference to Fig. 9, exhaust block 520 forms exhaust outlet 22 along the direction (y-axis direction) crossing with the laser beam irradiation direction (z-axis direction) of the second space 21 that laser beam passes, form inlet manifold 23 at the opposite side of exhaust outlet 22, and comprise and be connected to inlet manifold 23 and supply compressed-air actuated air inlet chamber 27.
