Description

Adapter plate welding heat dissipation tool

Technical Field

The utility model relates to a battery manufacturing technology field, concretely relates to switching piece welding heat dissipation frock.

Background

In the process of laser welding the adapter plate of the lithium ion battery, the negative electrode is welded by the copper sheet, the melting point of copper is higher, so that higher power is needed for welding, the generated instant heat is higher, and polyphenylene sulfide polymer (PPS) on the negative electrode is easily melted, so that the sealing property of the battery cell is influenced.

There are two existing improvement methods: firstly, in the welding process, one welding stamp is welded and cooled and then the next welding is carried out by a time-delay method, and the process is repeated until the welding is finished, so that the method has the defects of long time consumption, serious influence on productivity and non-conformity with actual production during continuous production; secondly, the length of the welding marks is shortened or the number of the welding marks is reduced, the welding power is reduced, so that the heat generated during welding is reduced, the welding tension and the welding residual area are not enough easily caused by insufficient welding energy, and finally, the generated finished product battery cell is not resistant to vibration and does not support large-current charging and discharging, so that the problem cannot be fundamentally solved, and therefore, the adapter plate welding heat dissipation tool needs to be provided to solve the problem.

Detailed Description

In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, the utility model is further explained by combining the specific implementation mode.

As shown in fig. 1-5, a switching piece welding heat dissipation frock, includes mounting panel 1, mounting panel 1 top is equipped with cooling module 2, in cooling module 2 top stretched into frock backup pad 3, adjustable anchor clamps subassembly 4 was installed to frock backup pad 3 top, anchor clamps subassembly 4 is used for spacing the product, the central point position lower extreme of cooling module 2 upper end connecting clamp subassembly 4 and cool down the positive negative pole switching piece of battery.

In this embodiment, the cooling assembly 2 includes the red copper piece 5, be equipped with the water inlet 6 and the delivery port 7 that run through on the red copper piece 5, the 5 lower extremes of red copper piece are equipped with screw rod 8, mounting panel 1 is connected to the 8 lower extremes of screw rod. The screw 8 is used for adjusting the height of the red copper block 5.

In this embodiment, the fixture assembly 4 includes a bottom plate 10 installed above the fixture supporting plate 3, a placing groove 11 for placing a product is provided in a center portion of the bottom plate 10, clamping plates 12 with symmetrical structures are provided at two ends of the placing groove 11, and the clamping plates 12 are installed on the bottom plate 10 through a snap. The clamp assembly 4 is used for limiting the product.

In this embodiment, the tooling support plate 3 is provided with a yielding groove 13, and the upper side of the red copper block 5 penetrates through the yielding groove 13 and is connected with the lower end of the placing groove 11.
