Description
Technical field
This utility model relates to field of cell preparation, is specifically related to lithium ion and produces equipment or method.
Background technology
Packaging lithium ion battery is high with its energy density, cycle life is good and makes the advantages such as diversification of forms and is favored by people, and become the main flow of current lithium ion battery, tab welding is then the critical process of flexible packing lithium ion battery, the direct qualification rate to lithium ion battery, resistance and the high rate performance thereof of its welding quality cause material impact, tab welding uses lug to weld with cell polar ear mostly at present, easily cause rosin joint, sealing-off and dislocation thereof, affect battery quality and the qualification rate of its soft-package battery.
Have by positioning fixture for welding soldering polar ear equipment although the most domestic, a kind of soft pack cell tab welding clamp of such as patent (CN 204538113 U), soft pack cell tab welding clamp makes soft package lithium battery cathode tab be difficult to dislocation when welding, ensure battery core encapsulation when lug in lug groove, but its operability is strong, poor for applicability and production efficiency is low.
Summary of the invention
The utility model discloses a kind of soft pack cell tab welding positioning fixture, it is provided that a kind of welding procedure is simple, improves welding efficiency, and effectively prevents the incomplete problem of rosin joint, sealing-off and pad, improves tab welding quality.
This utility model provides a kind of soft pack cell tab welding positioning fixture, 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 indicator 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 is 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.
Contact area and hot strength thereof to tab welding do experiment test, and result is: the bonding area of institute's soldering polar ear is 99%, 98%, 97%, far above the 90% of conventional proportional, it is respectively as follows: 90N/mm in hot strength 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 indicator, its bonding area is made to increase, positioning fixture makes all mean oscillatory heating of each position of soldering opening, weld the most firm, increase thus improve its hot strength, improve welding efficiency, and effectively prevent the incomplete problem of rosin joint, sealing-off and pad, improve tab welding quality.

Symbol description in Fig. 1-2: pole piece locating slot 1, draw-in groove 2, removable alignment pin 3, slide rail 5, level indicator 4, welding hole 6.
Detailed description of the invention
As shown in Figure 1-2, a kind of soft pack cell tab welding positioning fixture, 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 indicator 4 and multiple removable alignment pin 3, pole piece locating slot 1 is provided with welding hole 6 at top, and the side of welding hole 6 is provided with draw-in groove 2, and described removable alignment pin 3 is through to locating clip another side, the another side of tool positioning fixture is provided with slide rail 5, and slide rail 5 is between two removable alignment pins 3.
Production stage is as follows:
1. positioning fixture is positioned among ultrasonic bonding board by step by removable alignment pin 3;
2. step adjusts positioning fixture by level indicator 4 so that it is the soldering tip of bonding machine is in parastate with the bottom surface of draw-in groove 2;
3. battery core and lug are individually placed in pole piece locating slot 1 and draw-in groove 2 by step;
Step 4. shifting sledge 5 makes the weld of lug corresponding with ultrasonic welding machine soldering tip, can be to tab welding.
Contact area and hot strength thereof to tab welding do experiment test, and result is: the bonding area of institute's soldering polar ear is 99%, 98%, 97%, far above the 90% of conventional proportional, it is respectively as follows: 90N/mm in hot strength 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 indicator, its bonding area is made to increase, positioning fixture makes all mean oscillatory heating of each position of soldering opening, weld the most firm, increase thus improve its hot strength, improve welding efficiency, and effectively prevent the incomplete problem of rosin joint, sealing-off and pad, improve tab welding quality.
It is last that it is noted that obviously above-described embodiment is only for clearly demonstrating this utility model example, and not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.And the obvious change thus amplified out or variation still in protection domain of the present utility model among.
