Embodiment 1

[0032] An automatic turning device for a flexible circuit board printing machine, comprising a turning mechanism bracket 20 arranged on one side of the flexible circuit board printing machine 23, driven by a turning motor 22 on the turning mechanism bracket 20 The rotating shaft 21, the positioning plate 1 fixed on the rotating shaft 21 through the connecting piece 26, and the adsorption platform 12 arranged at the bottom of the positioning plate 1 through the buffer assembly 30;

[0033] Wherein, the buffer assembly includes a guide sleeve 2 fixed on the upper surface of the adsorption platform and a spring guide column 3 that moves up and down in the inner cavity of the guide sleeve 2; wherein the top end of the spring guide column 3 is fixed on the On the positioning plate 1, the upper outer edge of the spring guide column 3 is fixedly provided with an upper limiter 4 to form a support for the guide sleeve 2 in the overturned state, and the lower outer edge of the spring gui...

Embodiment 2

[0040] In this embodiment, on the basis of Embodiment 1, the shape and number of each component are optimized.

[0041] As a preferred manner, the positioning plate 1 is a rectangular plate, and the top end of the spring guide post 3 is fastened to the positioning plate 1 by screws. Simple structure, easy to assemble and assemble.

[0042] As a preferred manner, there are four buffer assemblies, which are respectively symmetrically arranged at four corners of the bottom of the positioning plate 1 . The symmetrically arranged structure makes the stress between the adsorption platform and the turnover plate more uniform.

[0043] As a preferred manner, the upper limit member 4 and the lower limit member 5 are respectively limit rings fixed on the upper and lower ends of the outer wall of the spring guide post 3 . The annular structure has a large stress surface.

Embodiment 3

[0045] In this embodiment, on the basis of Embodiment 1, the adsorption platform 12 is further improved.

[0046] The adsorption platform 12 includes a microporous plate 7 forming an adsorption surface, a boss 8 fixed on the top of the micropore plate 7 and an adsorption bottom plate 9 supported by the boss 8, wherein the upper part of the adsorption bottom plate 9 is Fitted with a pipe joint 10, the combination of the pipe joint 10, the groove formed between the bosses 8 and the microholes formed on the micropore plate 7 forms an airflow channel.

[0047] Way of working:

[0048] The suction fan is connected to the pipe joint 10 through a pipeline, and negative pressure is generated through the airflow channel. Since the micropores are densely covered with micropores, even if the sucked object (such as a flexible circuit board) does not cover the entire surface of the micropores, the negative pressure lost The pressure is still less, and enough negative pressure can be gener...

Abstract

The invention discloses an automatic board turnover device for a flexible circuit board spray printing machine. The automatic board turnover device comprises a board turnover mechanism bracket arranged on one side of the flexible circuit board spray printing machine, a rotary shaft driven by a board turnover motor to rotate on the board turnover mechanism bracket, a positioning plate fixed on therotary shaft, and an adsorption platform arranged at the bottom of the positioning plate through a buffering component; the buffering component comprises a guide sleeve fixed to the upper surface of the adsorption platform and a spring guide pillar capable of moving up and down in a cavity in the guide sleeve; the top end of the spring guide pillar is fixed on the positioning plate; an upper limiting piece is fixedly arranged on the upper outer edge of the spring guide pillar to support the guide sleeve in the turnover state; a lower limiting piece is fixedly arranged on the lower outer edge of the spring guide pillar; a spring is assembled between the lower limiting piece and a shrink opening in the top end of the guide sleeve; and a buffering adsorption table board can be used as a bearing platform.

Description

technical field [0001] The invention relates to the technical field of flexible circuit board inkjet printing, in particular to an automatic plate turning device for a flexible circuit board inkjet printer. Background technique [0002] The printed circuit board needs to be printed on both sides. After printing on one side, it needs to be turned over to print on the other side. However, due to the softness of the flexible circuit board, it is currently not possible to use the clamping of the hard board to realize the reversed printing of the circuit board. Can only rely on manual turnover. The efficiency of manual turnover is low, the positioning is inaccurate, and due to the improvement of printing efficiency, personnel are prone to fatigue due to long-term high-frequency operations. Contents of the invention [0003] The object of the present invention is to provide an automatic flipping device for a flexible circuit board jet printer in order to solve the problems of l...
