Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing, and in particular to an inkjet device for electronic circuit board manufacturing. Background Technology

[0002] Electronic circuit boards (PCBs) connect electronic components such as resistors, capacitors, and chips into a complete circuit system through pre-set conductive lines, enabling functions such as power transmission, signal processing, and logic control. Inkjet printing is a crucial process in PCB manufacturing, one of its core functions being the formation of a solder resist layer. This layer, typically composed of special insulating ink, is cured after inkjet printing and covers all conductive lines and substrate on the PCB except for solder pads, through-holes, and other areas requiring soldering. This prevents short circuits caused by solder flow during soldering and avoids oxidation, corrosion, or environmental factors such as dust and moisture affecting the electrical performance of the circuitry during subsequent use.

[0003] As electronic devices become smaller and more high-performance, circuit designs are becoming increasingly complex, requiring more electronic components and wiring space. Single-sided circuit boards have limited wiring area; when circuits contain numerous components and complex connections, single-sided wiring struggles to achieve all circuit connections and may even cause short circuits due to wiring intersections. Double-sided printing solves the wiring congestion problem by adding wiring space on one side, meeting the functional requirements of complex circuits. For example, circuit boards in precision electronic devices such as smartphones and computer motherboards rely on double-sided or even multi-layer wiring to achieve complex signal transmission and power supply functions.

[0004] To address the problems associated with double-sided printing on circuit boards, existing devices require manual flipping after printing one side to print the other side. This method is not only inefficient, but also prone to damaging the printed pattern due to the ink not yet being dry and cured by manual contact, severely affecting the printing effect.

[0005] To address this, we propose a device that eliminates the need for manually flipping the circuit board and accelerates ink drying. Utility Model Content

[0028] A drive unit 13 is provided in the transport section 11 and the drying section 12. The drive unit 13 includes two first electric slide rails 131 fixedly installed on the lower inner wall of the drying box 121 and the transport box 111, and two racks 132 fixedly installed on the side wall of the drying box 121 and the transport box 111.

[0029] A clamping mechanism 2 is provided within the transport section 11 and the drying section 12. The clamping mechanism 2 includes several moving parts 21 disposed within the transport section 11 and the drying section 12.

The moving part 21 also includes a rotating rod 213 rotatably disposed on the vertical rod 212, with two opposing rotating rods 213 forming a group. A gear 23 is fixedly disposed at one end of the rotating rod 213, and the gear 23 meshes with a rack 132.

[0030] The moving part 21 is provided with a clamping part 22, which includes a clamping plate 221 disposed on one side of a set of rotating rods 213. The clamping plate 221 has a "C" shaped longitudinal section. A circuit board body 24 is disposed between the two opposing clamping parts 22.

[0031] The clamping part 22 also includes a limiting plate 222 disposed in the clamping plate 221, and a bolt 223 disposed through the upper wall of the clamping plate 221. The bolt 223 is threadedly connected to the upper wall of the clamping plate 221, and the lower end of the bolt 223 is rotatably connected to the upper wall of the limiting plate 222.
