Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a thin substrate printing air suction platform. Background Art

[0002] The thin substrate printing suction platform is a device used in the printed circuit board manufacturing process. It is mainly used to absorb and fix the thin substrate (copper clad laminate) to ensure that the thin substrate will not move or deform during the printing process, thereby ensuring printing accuracy.

[0003] The existing thin substrate printing suction platform uses manual positioning and tape fixation during the process of laminating the printing jig sub-board and the copper-clad laminate. When manually positioning the board, if the position accuracy of the copper-clad laminate is not high enough, the printed pattern and position will deviate from expectations, resulting in the scrapping of the printed product. At the same time, when manually fixing the copper-clad laminate with tape, if the flatness of the printing jig sub-board is not enough, the tape will not be able to completely fit the surface of the copper-clad laminate, resulting in uneven local force during printing, wrinkles, and reduced production yield. Utility Model Content

[0004] The main purpose of the utility model is to provide a thin substrate printing suction platform, which aims to save the time of manual alignment and leveling of copper-clad laminates, improve production efficiency, and thus solve the adverse anomalies caused by manual operation to avoid the problem of low yield.

A positioning pin is installed on the bearing platform, and a first positioning hole and a second positioning hole cooperating with the positioning pin are provided on the printing jig sub-plate and the copper-clad laminated plate, respectively.

[0006] Optionally, a plurality of the positioning pins are provided, and the number of the first positioning holes and the second positioning holes is arranged corresponding to the number of the positioning pins.

[0007] Optionally, a buffer groove is further provided on the bearing platform, a sealing rubber ring is sleeved on the inner wall of the buffer groove, and the printing jig sub-plate is arranged on the sealing rubber ring.

[0008] Optionally, a board taking opening is provided on the carrying platform, and the board taking opening is located at one side of the buffer groove.

[0009] Optionally, a plurality of quick clamps are provided on the bearing platform, and the clamping heads of the quick clamps are extended above the printing jig sub-plate. The clamping heads of the quick clamps are provided with pressing pins for pressing the printing jig sub-plate.

[0011] Optionally, a suction fan is provided inside the frame body.

[0012] Optionally, a plurality of folding handles are provided on the outer wall of the frame body.

[0013] The beneficial effect of the utility model is that the printing jig sub-plate is installed by the cooperation between the positioning pin holes before being affixed to the copper foil laminate, thereby achieving fast and accurate positioning and ensuring the flatness and consistency of the printing jig sub-plate.

[0014] Afterwards, the copper-clad laminate and the carrier platform are also installed by matching the positioning pin holes, so that the product is horizontally and evenly adsorbed on the surface of the printing fixture, saving the time of manual alignment and flattening the copper-clad laminate, improving production efficiency, thereby reducing the rate of defective anomalies and avoiding the problem of low yield.

[0030] Finally, after the adsorption is completed, the start button is pressed again to disconnect the gas circuit, the printed jig sub-board 3 with the copper-clad laminate 4 attached thereto is removed, and the adsorption operation of the next copper-clad laminate 4 is continued.
