Disclosure of Invention

The utility model aims at providing a soft packet of FPC welding integral type hold-down mechanism of power battery, it has the location accurate, advantages such as welding stability. Overcomes the defects in the prior art.

In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides a soft packet of FPC welding integral type hold-down mechanism of power battery, including the copper clamp plate, copper clamp plate department is equipped with copper pressure head fixed plate, a plurality of bolt assembly chambeies have been seted up to copper pressure head fixed plate one side, form the wall portion between the adjacent bolt assembly chamber, the bolt through-hole with bolt assembly chamber intercommunication is seted up on copper pressure head fixed plate surface, be equipped with the bolt that corresponds the distribution with above-mentioned bolt through-hole in the bolt assembly chamber, every bolt outside has all cup jointed a spring and a briquetting, the nut of bolt is supported to the one end of spring, the other end of spring supports a briquetting terminal surface, another terminal surface of briquetting supports bolt assembly intracavity wall, two terminal surfaces of briquetting all are the rough terminal surface, bolt one end runs through above-mentioned bolt through-hole, bolt one end department has connect a copper pressure head soon, the constant head tank has been seted up to the terminal surface department of copper pressure head, the terminal surface department of above-mentioned nut is equipped with polygonal pinhole.

The utility model discloses a soft packet of FPC welding integral type hold-down mechanism of power battery, beneficial effect: the monomer separation type pressure head is changed into a whole. The existing monomer separation type pressure head only works one point position at a time, and the efficiency is low. On this basis, improve formula pressure head mode as an organic whole, do not influence under the condition of welding quality, effectively promoted welding efficiency. The mechanism can be adjusted by controlling the spring to control the movement of the working range of the pressure head, the range of the working pressure can be manually adjusted, and the position on the workbench can be manually adjusted, so that the mechanism is convenient and fast.
