Embodiment 1

[0042] Such as Figure 1 - Figure 3 As shown in the present invention, the present invention provides a battery pole pinch structure for pushing the aluminum pole of the battery into a solderable nickel belt, including battery clamp 100 and a nickel welding mechanism, wherein the nickel welding is used. The mechanism includes the laser welding device 200, the block assembly 300, and the top block assembly 400, and the battery clamp 100 is used to position the battery pole earlings, the top block assembly 400 is used to top support aluminum Ear ear, the block assembly 300 is configured to take a vertical state when the aluminum pole is smooth, 90 °, vertically opposed to the aluminum pole and nickel belt are passed closely to the block assembly 300 and the top block assembly 400. Fixed, the laser welding device 200 is used to weld the nickel tape and an aluminum pole.

[0043]When the battery pole is transferred, the aluminum pole ear is supported by the top block assembly 400, and ...

Embodiment 2

[0062] Combine Figure 4 As shown, the second embodiment of the present invention provides a transfer method of the battery pole pinch structure described in the first embodiment, including the following steps:

[0063] Step S0: Start the block assembly 300 so that the block assembly 300 rises to a position higher than the extract of the battery to be placed;

[0064] Step S1: The battery clamp 100 moves the fabricated battery from the previous step to level fixed, at which point the aluminum polar ear is toward the nickel welding mechanism;

[0065] Step S2: Starting the top block assembly 400 causes the top block body 410 to abut against the lower end surface of the aluminum pool;

[0066] Step S3: Start the block assembly 300 and move the aluminum pole scrape 90 ° vertically by moving down the aluminum pole.

[0067] Step S4: Place the nickel tape vertically in the position of the vertical aluminum pole ear.

[0068] Step S5: The startup block assembly 300 is moved to the top b...

Abstract

The invention discloses a battery tab switching structure and method. The battery tab switching structure comprises a battery clamp and a nickel switching welding mechanism, wherein the nickel switching welding mechanism comprises a laser welding device, a pressing block assembly and an ejecting block assembly; during switching, the battery clamp is used for positioning battery tabs to enable thealuminum tabs to be horizontally placed, the ejecting block assembly is used for jacking and supporting the aluminum tabs, the pressing block assembly is used for bending the aluminum tabs clockwise by 90 degrees to form a vertical state, the aluminum tabs and a nickel strip which are vertically aligned are tightly attached and fixed by the pressing block assembly and the ejecting block assembly,and the laser welding device is used for welding the nickel strip and the aluminum tabs. According to the battery tab switching structure, the aluminum-to-nickel structure space occupation of batteries is small, the structure is simple, and the switching quality and stability are good.

Description

Technical field [0001] The present invention relates to the production of a lithium ion polymer battery, and more particularly to a battery polar ear pinch structure and a transfer method. Background technique [0002] The polymer battery has the advantages of good safety, high energy density, dimensional size, and is widely used in various portable power plants such as mobile phones, laptops, cameras, wear products. [0003] Typically, the polymer battery has a positive electrode terminal and a negative electrode terminal (hereinafter referred to as the extreme ear) to connect to an external electrical device. Based on electrochemical reasons, the current positive terminal (positive ears) has a thickness of 0.06 mm to 0.12 mm, a width of 2 mm to 6 mm aluminum band (aluminum pole ear). Due to poor weldability of aluminum, it is difficult to connect with the electric device, and therefore, in the production of polymer battery, the aluminum pole ear is usually transferred into a so...
