Description

Technical Field

[0001] The utility model relates to the technical field of traceability code dot printing, in particular to a mechanism for micro-nano light focusing dot printing of traceability codes. Background Art

[0002] With the rapid development of electronic technology and the continuous growth of the demand for electronic products, the PCB industry is facing increasingly high production requirements and challenges. Product traceability has changed from traditional date stamps to a one-to-one QR code information storage method. The old PCB traceability code production method will cause relatively large pollution to the PCB production line and cannot meet the high-speed production on site. Therefore, as one of the important equipment in the electronic manufacturing industry, the technical level and application scope of PCB traceability code dot printing equipment are also constantly improving and expanding.

[0003] The PCB traceability dot spraying and printing equipment of this design adopts advanced digital inkjet printing technology, which can significantly improve the production efficiency and traceability content of PCB boards. Compared with traditional methods such as laser engraving printing, digital inkjet printing technology has a higher degree of automation and a faster printing speed, thus shortening the production cycle while increasing traceability information. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that there is a disadvantage of low production efficiency in the prior art. For this reason, we propose a mechanism for micro-nano light focusing dot printing of traceability codes.

[0005] In order to achieve the above object, the present application adopts the following technical solution: A mechanism for micro-nano light focusing dot printing of traceability codes, including a dot printing device, a protective shell is installed on the top of the dot printing device, a connecting rod is fixedly connected to the top of the dot printing device, the top end of the connecting rod is fixedly connected to an installation bar, and a printing module is installed on one side of the installation bar.

[0006] Preferably, a vision module is installed at the bottom of the installation bar.

[0007] Preferably, an automatic track-changing module is installed at the top end of the dot printing device.

[0008] Preferably, a heat dissipation mechanism is installed on one side of the printing module.

[0009] Preferably, a vision camera is installed at the bottom of the vision module.

[0010] Preferably, a UV curing lamp is installed on the top of the printing module.

[0011] The technical effects and advantages of the utility model:

[0012] In the present utility model, first, the information in the traceability code is imported into the inkjet printing software to generate the traceability code. Secondly, the PCB board is placed at the equipment feeding port to remove the static electricity on the board and detect the deformation amount. The qualified products proceed to the next step, while the unqualified products directly flow to the rejection station. After the qualified products reach the predetermined inkjet printing position, the inkjet printing position on the PCB board is located by a vision camera, and then the traceability code is inkjet printed on the PCB board through the inkjet printing module and cured. Subsequently, the two-dimensional code after inkjet printing is read again by the vision camera. The traceability code that can be successfully read is a qualified product and flows to the next production link, while the unqualified products flow to the rejection station for rejection. The whole process adopts fully digital automated operation, which is simple, convenient and safe in operation. Description of the Drawings
