Auxiliary pressing device for rigid-flex board

Abstract

The invention discloses an auxiliary pressing device for a rigid-flex board. The auxiliary pressing device comprises an upper pressing plate and a lower pressing plate. The upper surface of the upperpressing plate is connected with the main frame through a plurality of springs; the lower surface of the lower pressing plate is connected with a sliding block through a connecting column, the slidingblock can move up and down along a vertical sliding rail, a horizontal air cylinder is arranged on the side face of the sliding rail, a guide rail groove set is formed in the surface of the sliding block, and the guide rail groove set comprises a first guide rail groove, a second guide rail groove and a third guide rail groove which are connected in sequence. A pulley is arranged at the front endof a push rod of the horizontal air cylinder and embedded into the guide rail groove set. Compared with a traditional air cylinder press fit mode, the mode that the sliding block, the guide rail, thespring, the upper pressing plate and the lower pressing plate are matched is adopted in the device, so that the whole heating and press fit process of the rigid-flex printed circuit board is rapidlycompleted, the machining efficiency is high, and the press fit speed is high.

Description

technical field [0001] The invention relates to an auxiliary pressing device for soft and hard combination boards. Background technique [0002] Rigid-flex circuit board is a circuit board with FPC characteristics and PCB characteristics formed by combining flexible circuit boards and rigid circuit boards through lamination and other processes according to relevant process requirements. It has light weight, small size, and three-dimensional space. It has the advantages of bending, stretching, folding, etc., but the efficiency of the traditional pressing device is low, and the pressing quality is poor. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned deficiencies in the prior art, and propose an auxiliary pressing device for rigid-flex boards. [0004] An auxiliary pressing device for soft and rigid boards, including an upper pressing plate and a lower pressing plate; [0005] The upper surface of the upper platen is ...
