Description

Circuit board pressing device Technical Field The invention relates to the field of circuit board production devices, in particular to a circuit board pressing device. Background Lamination of a plurality of single-layer circuit boards (also called circuit boards or printed circuit boards) refers to laminating a plurality of single-layer circuit boards together by a certain method and process, and applying proper pressure for fixing, wherein the process aims at connecting the circuits of the single-layer circuit boards to form an integral multi-layer circuit board structure. In practical manufacturing, before stacking and laminating, conventional multilayer circuit boards are usually stacked together and transferred manually, and laminated by using a laminating mechanism, and then the processed circuit boards are manually taken. The patent application number CN202320148557.4 discloses a circuit board pressing jig, which comprises a main body mechanism, an adjusting mechanism and a pressing mechanism, wherein the pressing mechanism comprises a lower jig, a limiting ring, a positioning upright post, a pressing groove, a supporting frame, a supporting cross rod, an electric push rod, a push rod, an upper jig, a positioning hole and an upper pressing groove, the lower jig is fixedly arranged at the upper end of a working panel, and the limiting ring is fixedly arranged at the upper end of the lower jig. The circuit board is placed on the lower jig, the electric push rod is started to push the push rod to descend, so that the electric push rod pushes the upper jig to press the circuit board on the lower jig, but after the circuit board of the device is pressed, the circuit board to be pressed needs to be taken down and placed, the next pressing can be started, and the pressing efficiency of the circuit board is seriously affected.
