Ink jetting device printing head for printed circuit board

Abstract

The invention discloses an ink jetting device printing head for a printed circuit board. The ink jetting device printing head comprises printing head devices and a lateral connecting rod. A clamping groove is formed in one side of a fixed connecting column. Air blowing devices are arranged on one sides of the printing head devices. The lower ends of the air blowing devices are provided with air outlet pipelines and air outlets. One end of the lateral connecting rod is provided with a fixed cross rod. A movable connecting rod is arranged on the other side of the lateral connecting rod. Distancescales are arranged on the outer surface of the lateral connecting rod. The ink jetting device printing head for the printed circuit board is provided with the air blowing device, the movable connecting rod and the clamping groove, so that ink oil which is just sprayed onto the circuit board can be blow-dried by hot air blown out, and the condition that the ink oil cannot be fixed to the circuitboard in a short time is avoided. The distances between the printing head devices are controlled within a reasonable range by sliding the printing head devices left and right and observing the distance scales. The ink jetting device printing head for the printed circuit board is applicable to different working conditions and has a better application prospect.

Description

technical field [0001] The invention relates to the field of circuit board printing equipment, in particular to an inkjet printing head for a printed circuit board. Background technique [0002] In the past, circuit boards were generally printed by hand. Although hand-printed circuit boards can completely print circuit boards that are difficult to print according to their own needs, the efficiency of manual printing will be greatly reduced. At the same time When manually printing circuit boards, the printed circuit board may not be complete due to inattentive work. After connecting to the device, the circuit cannot be turned on, which brings a lot of trouble to the production and processing of the circuit board. On the board equipment, the most important thing is reflected in its print head. Only when the print head is designed to be suitable for most types of circuit boards can it truly overcome most of the problems that may occur during the circuit board printing process. ...

Problems solved by technology

[0002] In the past, circuit boards were generally printed by hand. Although hand-printed circuit boards can completely print circuit boards that are difficult to print according to their own needs, the efficiency of manual printing will be greatly reduced. At the same time When manually printing circuit boards, the printed circuit board may not be complete due to inattentive work. After connecting to the device, the circuit cannot be turned on, which brings a lot of trouble to the production and processing of the circuit board. On the board equipment, the most important thing is reflected in its print head. Only when the print head is designed to be suitable for most types of circuit boards can it truly overcome most of the problems that may occur during the circuit board printing process. At the same time, after the emergence of inkjet printing devices, circuit board printing technology has been greatly improved, and mechanized production has been realized on the basis of traditional manual technology.

[0003] There are certain drawbacks in the use of the existing inkjet device printheads for printed circuit boards. After the printhead sprays the ink, it does not dry the ink through any cooling device, and the ink is fixed on the circuit board. , it is impossible to manually change the distance between adjacent print heads, and it is also not suitable for different types of circuit boards. When different numbers of print heads are required, it is impossible to conveniently move the print heads that are not needed. It is very inconvenient to use and has a certain impact on printing and inkjet. Therefore, we propose an inkjet print head for printed circuit boards.
