Pressing device on aluminum substrate production line

Abstract

The invention aims at providing a pressing device on an aluminum substrate production line. The pressing device comprises a machine base, a hot pressing assembly and a cold pressing assembly, the hot pressing assembly and the cold pressing assembly are assembled on the machine base, an annular rail is assembled on the machine base, the hot pressing assembly and the cold pressing assembly are located on the outer side of the annular rail, and at least two sliding seats are installed on the annular rail in a sliding mode. A machine frame further comprises a driving mechanism used for driving the sliding seats to slide on the annular rail, a vertically-through step groove is formed in the outer side portion, away from the annular rail, of each sliding seat, a separating seat is erected on the step groove, jacking cylinders are arranged at the positions, located at the hot pressing station and the cold pressing station, of the machine base respectively, a lifting plate is fixedly installed at the top end of a movable rod of the jacking cylinder, and a limiting mechanism is arranged between the lifting plate and the separating seat. The hot pressing assembly comprises a first rack, a first pressing cylinder and a hot pressing plate, the first rack is fixedly installed on the machine base, and the first pressing cylinder is fixedly installed on the top of the first rack.

Description

technical field

[0001] The invention relates to a pressing device, in particular to a pressing device on an aluminum substrate production line. Background technique

[0002] Aluminum substrate is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single-sided panel is composed of three layers, which are circuit layer, insulating layer and metal base layer. Single-sided double-layer aluminum substrate has two layers of conductive graphics. The printed circuit board is made of alternating lamination and bonding with the insulating layer and the aluminum substrate. The insulating layer is the core technology of the aluminum substrate, which mainly plays the functions of bonding, insulation and heat conduction. The insulating layer of the aluminum substrate is the structure of the power module. The largest thermal barrier in the insulation layer, the better the thermal conductivity of the insulating layer, the more conducive to the diffusion of ...
