Problems solved by technology

[0003] During the production and processing of large lithium battery packs, small single lithium batteries are assembled together to form a lithium battery pack, and then the welding pieces are welded on the lithium battery pack. It is to manually place the welding pieces on the lithium battery pack in sequence, and then put them into the spot welding machine for sequential welding, so the welding efficiency is very low, and the automatic docking of the welding pieces and the lithium battery pack cannot be realized.

Embodiment 1

[0031] see Figure 1-3 , a collision-proof lithium battery pack welding device, including a first conveyor belt 1, a second conveyor belt 4 and a transfer plate 3, the first conveyor belt 1 is provided with evenly distributed lithium battery packs 12, and the second The output end of a conveyor belt 1 is provided with an inclined downward transfer plate 3, and the transfer plate 3 is provided with symmetrically distributed deflectors 31, and the extension end of the transfer plate 3 is provided with a fixedly connected baffle plate 33 The baffle 33 and the deflector 31 are connected and fixed to each other, and the transfer plate 3 on one side of the baffle 33 is provided with a transfer hole 34, and the transfer hole 34 is provided with a symmetrical distribution. and a telescopic positioning plate 341, and a second conveyor belt 4 is provided below the transfer hole 34, and the positioning box 2 that is evenly distributed and matched with the lithium battery pack 12 is provi...

Embodiment 2

[0038] The same as embodiment 1 is not repeated, and the difference with embodiment 1 is:

[0039] see Image 6 The baffle plate 33 is provided with a pressure sensor 32 for sensing, and the inner walls of both sides of the transfer hole 34 are provided with symmetrically distributed adjusting grooves 342, and the positioning plate 341 is slidably connected in the adjusting groove 342, so that A fixedly connected second hydraulic rod 343 is arranged inside the adjustment groove 342 , and the extension end of the second hydraulic rod 343 is connected and fixed to the end of the positioning plate 341 .

[0040] The design of the pressure sensor 32 realizes the automatic control of the lithium battery pack 12 through the induction of the pressure sensor 32 and improves the overall efficiency.

[0041] Further, the second hydraulic rod 343 is an electro-hydraulic push rod, and the pressure sensor 32 is electrically connected to the second hydraulic rod 343 .

Embodiment 3

[0043] The same as embodiment 1 is not repeated, and the difference with embodiment 1 is:

[0044] see Figure 7-8 , the positioning box 2 is a square frame, and the positioning box 2 is provided with a welding plate 21 that can move up and down. The middle part of the welding plate 21 is provided with a welding hole 23 for welding. The welding plate 21 is provided with a welding groove 22 for engaging the welding piece 24 .

[0045]The unique design of the positioning box 2 enables the welding plate 21 to move upwards directly when the first hydraulic rod 51 rises, so that the welding plate 21 can be closer to the transfer hole 34, effectively preventing the lithium battery pack 12 from automatically When falling, the distance is too far, resulting in vibration damage to the lithium battery pack 12, and can effectively improve the drop accuracy of the lithium battery pack 12. When the first hydraulic rod 51 descends, the positioning box 2 contacts the second conveyor belt 4 ...

Abstract

The invention belongs to the technical field of lithium battery welding, and particularly relates to an anti-collision lithium battery pack welding device which comprises a first conveying belt, a second conveying belt and a transferring plate. Lithium battery packs are evenly distributed on the first conveying belt, and the transferring plate inclining downwards is arranged at the output end of the first conveying belt. Flow guide plates which are symmetrically distributed are arranged on the transferring plate, a baffle which is fixedly connected is arranged at the extending end of the transferring plate, the baffle and the flow guide plates are mutually connected and fixed, transferring holes are formed in the position,located on one side of the baffle, of the transferring plate, positioning plates which are symmetrically distributed and can stretch out and draw back are arranged in the transferring holes, and the second conveying belt is arranged below the transferring holes. Positioning boxes which are evenly distributed and matched with the lithium battery packs are arranged on the second conveying belt, welding pieces used for welding the lithium battery packs are arranged in the positioning boxes, automatic boxing of the lithium battery packs is achieved, and automatic butt joint of the lithium battery packs and the welding pieces is achieved.

Description

technical field [0001] The invention belongs to the technical field of lithium battery welding, and in particular relates to an anti-collision lithium battery pack welding device. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S.Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream. [0003] During the production and processing of large lithium battery packs, small individual lithium batteries are assembled together to form a lithium battery pack, and then the welding pie...
