Description

Technical Field

[0001] The utility model relates to the technical field of lithium ion battery soft package module processing, in particular to a lithium ion battery soft package module welding positioning device. Background Art

[0002] The positive and negative tabs of the lithium-ion battery soft-pack module are the metal conductors that lead the positive and negative electrodes out of the battery cell. During the PACK production process, welding is usually used to connect the tabs of the soft-pack module to the pads of the BMS adapter board to form a connection between the module and the BMS system.

[0003] A lithium-ion battery soft-pack module welding positioning device disclosed in the Chinese utility model patent application disclosure CN218918980U, although the utility model has high welding efficiency, is not prone to crooked welding, cold welding and the like, and makes the welding of the pole ears on multiple soft-pack battery cells consistent, the welding quality is high, so that the performance of the entire soft-pack module can be guaranteed, but this device lacks a device for testing whether the welded batteries are firmly welded, which can easily cause the problem of detachment of the later welds due to loose welding, and also lacks a device that can arbitrarily adjust the internal space of the overall equipment to clamp and weld multiple groups of batteries at the same time, which can easily cause the problem that the internal space of the overall equipment is too small to clamp and position multiple groups of batteries due to the need to weld multiple groups of batteries at the same time. Therefore, we propose a new device to solve the above problems. Utility Model Content

Through the lead screw motor and the lead screw, the extrusion plate can be driven to extend and retract inside the left box to clamp the lithium-ion battery, avoiding the problem that multiple groups of batteries cannot be firmly clamped when they need to be clamped and welded at the same time. By tightening the bolts, the multiple groups of batteries can be placed inside for clamping when they need to be clamped and welded at the same time, avoiding the problem that the internal space of the left box and the right box is too small, which makes it inconvenient to place multiple groups of lithium-ion batteries inside for clamping.

The problem of breaking or loosening of the welding position due to excessive temperature when the battery is used later can be avoided. Through the protective pad, the effect of protecting the battery when the splint drives the battery to shake and collide can be achieved, avoiding the problem of damage to the battery caused by multiple shaking and collisions inside the placement box.

[0017] 2. In the utility model, the handle can be used to cover the cover when the interior of the placement box needs to be heated, thereby avoiding the problem that the internal temperature cannot flow out and the interior of the placement box cannot be heated due to the inability to seal the placement box. By adjusting the button and the compression spring, the position of the adjustable fixing plate can be adjusted so that the extrusion plate cooperates with the fixing plate to clamp and fix the battery, thereby avoiding the problem that the extrusion plate cannot fix the battery.

[0018] 3. In the utility model, the fixing frame can be used to place the battery to be welded inside the fixing frame so that the extrusion plate and the fixing plate can clamp the fixing frame, thereby avoiding the problem of damage to the battery caused by the extrusion plate and the fixing plate clamping the battery for a long time. By using the clamping plate, when multiple groups of batteries need to be welded, multiple fixing frames can be placed side by side and clamped together, thereby avoiding the problem of inaccurate battery welding caused by offset due to the inability of the fixing frames to be clamped in parallel. By using the collection box, the welded batteries can be temporarily stored inside the collection box and taken away together later, thereby avoiding the problem of the staff taking away one group for storage after welding one group of batteries.

The battery can be fixed by the fixing frame 22. The battery to be welded can be placed inside the fixing frame 22 so that the extrusion plate 8 and the fixing plate 21 can clamp the fixing frame 22, avoiding the problem of the extrusion plate 8 and the fixing plate 21 clamping the battery for a long time and causing damage to the battery.
