Automatic turnover device for printed circuit board

Abstract

The invention provides an automatic turnover device for a printed circuit board, and belongs to the technical field of printed circuit board preparation. The device comprises a linear mechanism, a rotating mechanism, a width adjusting mechanism and a clamping mechanism; the rotating mechanism comprises a seat body arranged on the linear mechanism and a rotating air cylinder arranged on the seat body; the width adjusting mechanism comprises a shell, a gear, a width adjusting motor and a rack, the shell is connected with a rotating shaft of the rotating air cylinder, two strip-shaped through holes are formed in one side face of the shell, the rack is in sliding fit with a horizontal guide rod, the horizontal guide rod is arranged on the inner wall of the shell, connecting strips are arranged on the top face of the rack, and penetrating rods are connected to the connecting strips, the two penetrating rods extend out of the strip-shaped through holes respectively and are connected with L-shaped frames located outside the shell respectively; the clamping mechanism is installed on the L-shaped frames. According to the automatic turnover device, automatic turnover is achieved to replace manual operation, conveying of a front silk-screen procedure and a rear silk-screen procedure is carried out; the automatic turnover device is high in flexibility and can adapt to circuit boards of different sizes and can adapt to the situation that conveying slightly deviates and is high in practicability.

Description

technical field [0001] The invention relates to the preparation technology of printed circuit boards, in particular to an automatic overturning device for printed circuit boards. Background technique [0002] The preparation process of printed circuit boards involves screen printing steps. For some printed circuit boards, double-sided printing is required. Silk screen printing is not the same, generally divided into two screen printing stations. At present, one more operator is used between the two silk-screen printing stations to manually flip the circuit boards delivered after the first silk-screen printing is completed, and then place them on the conveying table of the second silk-screen printing station; The advantage of the work operation is that it can cope with the flipping of various shapes of circuit boards, and has good adaptability, but the efficiency is low, and the work intensity is not low. In the process of efficient production, additional manpower is require...
