Have by positioning fixture for welding soldering polar ear equipment although domestic at present, such as a kind of soft pack cell tab welding clamp of patent (CN204538113U), soft pack cell tab welding clamp not easily misplaces when soft package lithium battery cathode tab is welded, ensure battery core encapsulation in lug in lug groove, but its operability is strong, poor for applicability and production efficiency is low.
Summary of the invention
The invention discloses a kind of soft pack cell tab welding positioning fixture and welding method thereof, provide a kind of welding procedure simple, improve welding efficiency, and effectively prevent the incomplete problem of rosin joint, sealing-off and pad, improve tab welding quality.
The invention provides a kind of soft pack cell tab welding positioning fixture and welding method thereof, the one side of described positioning fixture is provided with pole piece locating slot 1, the bottom of pole piece locating slot 1 is provided with level meter 4 and multiple removable alignment pin 3, pole piece locating slot 1 is provided with welding hole 6 at top, the side of welding hole 6 is provided with draw-in groove 2, described removable alignment pin 3 passes through to locating clip another side, and the another side of tool positioning fixture is provided with slide rail 5, and slide rail 5 is between two removable alignment pins 3.
Described welding method comprises following production stage:
1. positioning fixture is positioned among ultrasonic bonding board by removable alignment pin 3 by step;
2. step adjusts positioning fixture by level meter 4, makes the bottom surface of the soldering tip of its bonding machine and draw-in groove 2 be in parastate;
3. battery core and lug are placed in pole piece locating slot 1 and draw-in groove 2 by step respectively;
Step 4. shifting sledge 5 makes the weld of lug corresponding with ultrasonic welding machine soldering tip, can to tab welding.
The following material mixture ratio of described positioning fixture forms: aluminium oxide 1 ~ 5%, iron 70 ~ 95%, carbon 1 ~ 20%, aluminium 1 ~ 2%, sodium oxide molybdena 1 ~ 2%, cupric oxide 5 ~ 8.
Experiment test is done to the contact area of tab welding and hot strength thereof, result for: the bonding area of institute's soldering polar ear is 99%, 98%, 97%, far above 90% of conventional proportional, be respectively in hot strength: 90N/mm simultaneously, 87N/mm, 82N/mm, far above the 65N/mm of convention control's example.Its reason makes its lug, battery core and bonding machine soldering tip be parallel to each other due to level meter, its bonding area is increased, adopt above-mentioned material to strengthen ultrasonic bounce-back simultaneously, make all mean oscillatory heatings of each position of soldering opening, welding is just more firm, increases thus improves its hot strength, improve welding efficiency, and effectively prevent the incomplete problem of rosin joint, sealing-off and pad, improve tab welding quality.
