Description

Circuit board barcode printing device

The present invention relates to a circuit board barcode printing device, and more particularly to a printing device applied to a circuit board for laying an unpeelable printed substrate on a circuit board and printing the barcode on the printed substrate.

To facilitate production process management, current boards are usually printed with identification barcodes, such as 2D barcodes. At present, one method is to first apply a liquid background color on a circuit board, dry it, and then print the barcode on the ground layer.

The surface of the board is usually a solder mask, the color of which is dark, such as green, black, and blue. The background layer is usually white. In order to produce sufficient contrast to facilitate reading of the barcode, it is sometimes necessary to coat the undercoat layer multiple times. This way delays production time and reduces production efficiency.

The present embodiment is directed to providing a circuit board barcode printing apparatus that provides a bar code of sufficient contrast on a circuit board and maintains production efficiency.

In order to achieve the above, a circuit board barcode printing device provided by one embodiment of the present invention is for printing a barcode on a circuit board. The circuit board barcode printing device comprises a ribbon laying module and a curing module. And a printing module. The ribbon laying module comprises a tape take-up unit, a tape unit located at one side of the tape take-up unit, a crimping roller, and a bottom color tape, and the bottom color tape is wound on the tape single And passing through the crimping roller, wherein the base color ribbon comprises a release layer, and a layer of curable material is disposed on the release layer. The curing module is disposed on one side of the ribbon laying module to cure the layer of the curable material of the underlying ribbon on the circuit board. The printing module is disposed on one side of the ribbon laying module to print a barcode on the cured layer of the curable material.

The beneficial effect of the present invention is that the circuit board barcode printing device provided by the embodiment of the present invention can have a predetermined thickness by the bottom color strip to generate sufficient contrast to facilitate reading of the printed barcode and avoid the use of the barcode. It is known that the contrast of the liquid-like undercoat layer is insufficient and the coating is repeated, or the bar code printing is failed and the production efficiency is lowered.
