On, cutting process is carried out to grid；Trapeze cut is arranged upward, frame rolled edge deformity during cutting knife incision, is avoided；
(3) grid cut is sent into the cream equipment that applies, by applying during cream bucket, with trapeze cut one faces grid
On, lead plaster gets off and lead plaster will be also filled in trapeze cut from cream bucket is applied, and is then dried；If one side of the grid with trapeze cut
Down, due to the stop of grid frame, in trapeze cut, just do not apply lead plaster；
(4) grid facing up with trapeze cut after cream, saw blade rotation direction and grid direction of motion phase will be applied
Instead, cutting obtains pole plate；Due to the support force of grid frame, the lead plaster in trapeze cut would not depart from side because cutting power
Frame, solves the problems, such as to cut the fried cream of pole plate.
The beneficial effects of the utility model are：Grid frame is designed by this utility model by the improvement to grid frame
Into hierarchic structure, one be to maintain grid original thickness it is constant, it is ensured that grid fills the void volume of lead plaster, it is to avoid occur building
Cream phenomenon；Two specific surface areas for being the increase in lead plaster, improve the high-rate performance of lead-acid accumulator；Three are the reduction of rare earth silver
The consumption of alloy, has saved material cost.
