Description

Technical Field

[0002] Tabs are a raw material for lithium-ion polymer battery products. For example, mobile phone batteries, Bluetooth batteries, laptop batteries, etc. in our daily lives all need tabs.

[0003] The battery has positive and negative poles. The tabs are metal conductors that lead the positive and negative poles out of the battery cell. In layman's terms, the tabs of the positive and negative poles of the battery are the contact points during charging and discharging. This contact point is not the copper sheet on the outside of the battery that we see, but a connection inside the battery. Tabs are divided into three types of materials. The positive pole of the battery uses aluminum (Al) material, the negative pole uses nickel (Ni) material, and the negative pole also has copper-plated nickel (Ni-Cu) material. They are all composed of two parts: film and metal strip.

[0004] Soft-pack lithium batteries are just liquid lithium-ion batteries covered with a polymer shell. They are structurally packaged in aluminum-plastic film. In the event of a safety hazard, the soft-pack battery will only bulge and crack at most, and has good safety performance.

When performing the welding operation, the power motor 303 is started, and one of the transmission rollers 314 is driven to rotate by the power motor 303. Since the two gear members 313 are meshed, the two transmission rollers 314 are rotated at the same time, and then the connecting rib 309 is rolled up by the transmission roller 314. As the connecting rib 309 is rolled up, the opening and closing plate 312 will move out of the opening and closing port, and the battery push plate 308 will move into the rectangular port. At this time, the pole ear moves with the opening and closing plate 312 and falls on the placement groove 6.

After that, the power motor 303 is reversed, and the opening and closing plate 312 is reset with the return spring 311 to close the pole ear placement port 302. The battery push plate 308 is reset with the return spring 306. At the same time, the next soft-pack battery falls at the bottom of the battery placement port 305 for subsequent pushing.

[0042] In a specific application scenario, the placement module 3 is suitable for the placement and loading of soft-pack batteries and tabs, that is, the placement module 3 can pre-place soft-pack batteries and tabs when in use, thereby increasing the use effect and diversity of the equipment during the welding process, and the device can automatically place the soft-pack batteries and tabs one by one when performing welding operations, so that the staff does not need to frequently place the soft-pack batteries and tabs during use, so as to further increase the operation convenience of the equipment and further reduce the work intensity of the staff.

[0043] The soft pack battery tab welding method uses the soft pack battery tab welding device as described above, comprising the following steps:

[0044] Step 1: pre-place the soft-pack battery and the pole ear in the pole ear placement port 302 and the battery placement port 305. When performing the welding operation, start the power motor 303, and drive one of the transmission rollers 314 to rotate through the power motor 303. Since the two gear members 313 are meshed, the two transmission rollers 314 rotate at the same time, and then the connecting rib 309 is rolled up by the transmission roller 314. As the connecting rib 309 is rolled up, the opening and closing plate 312 will move out of the opening and closing port, and the battery push plate 308 will move into the rectangular port. At this time, the pole ear moves with the opening and closing plate 312 and falls on the placement groove 6. At the same time, the battery push plate 308 pushes the soft-pack battery into the placement groove 6 to complete the placement of the soft-pack battery and the pole ear;

[0045] Step 2: After placement, start the air pump 913. The air pump 913 can make the negative pressure chamber 904 in a negative pressure state through the connecting pipe 908, so as to fix the negative pressure chamber 904 with the tab through the negative pressure port. At the same time, as the negative pressure chamber 904 is in a negative pressure state, negative pressure is also generated inside the connecting chamber 903, so that the fixing suction cup 902 fixes the soft-pack battery;

[0046] Step 3: During welding, when the soft-pack battery and the tab to be welded move to the bottom of the welding equipment body 15, the air pump 913 can cooperate with the fixed suction cup 902 and the negative pressure chamber 904 that are not fixed to deliver air to the inside of the connecting pipe 908, and further improve the connecting ball 914 to deliver air to the inside of the delivery pipe 912 and the connecting pipe 901, and then deliver it to the air evolver through the connecting pipe 901, and then clean the welding part through the cleaning nozzle 907, and then the electric push rod 16 starts to drive the welding equipment body 15 to descend for welding operation;

[0047] Step 4: After welding, when the welded soft-pack battery and the tab move with the welding seat 7 to the top of the electric telescopic rod 802, the electric telescopic rod 802 is started, and the mounting frame 804 drives the fixed rod 812 and the elastic plug rod 811 to move toward the side of the welding seat 7, and the elastic plug rod 811 is plugged with the docking piece 810 on the welding seat 7. At this time, the stepper motor 805 is started, and the stepper motor 805 can drive the winding wheel 806 to wind up the connecting wire 807, so that the connecting wire 807 pulls the connecting piece 813 and the fixed rod 812. It descends, and the limiting slider 814 moves inside the guide groove 815. At the same time, as the fixing rod 812 descends, the elastic plug rod 811 and the elastic frame 12 are deformed, thereby driving the welding seat 7 to tilt. At this time, as the welding seat 7 descends, the pushing ball 818 can contact the sealing member 910, thereby compressing the pressure spring 911, and then the negative pressure state inside the negative pressure chamber 904 and the connecting chamber 903 is lost, so as to cancel the fixation of the soft-pack battery and the pole ear, and further make the soft-pack battery and the pole ear slide off, and finally be collected by the staff.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
