Description

TECHNICAL FIELD

[0001] The utility model relates to a double -sided character automatic jet printing machine. BACKGROUND

[0002] In the field of electronic manufacturing, character jet printing of circuit board is an important production link. Traditional jet printing method is usually single -sided jet printing, and for the circuit board needing double -sided jet printing, it usually needs to go through complex operation process. For example, first feeding and jet printing on one side of the circuit board, then turning over, and then jet printing on the other side. This process may involve manual turning over or simple mechanical turning over device cooperating with jet printing equipment.

[0003] Disadvantages of prior art:

[0004] 1. Low automation:

[0005] The operation links of traditional jet printing machine such as feeding, moving, turning over, discharging and the like are usually relatively independent, and need manual intervention or cooperation of multiple simple automatic devices. For example, after turning over the circuit board, it may need to be placed in another jet printing station manually, or the coordination between different mechanical arms is not accurate enough, resulting in that the whole jet printing process is not smooth enough, and the production efficiency is reduced.

[0006] 2. Limited jet printing efficiency:

[0007] For double -sided jet printing, it cannot be efficiently completed in the same equipment. The traditional equipment may need to repeatedly transmit the circuit board between two jet printing devices, or wait for the jet printing of one side to be completed before jet printing the other side. The space and time of jet printing device and workbench are not fully utilized, so that the jet printing capacity per unit time is low.

[0008] 3. Poor jet printing precision and curing effect:

[0009] The existing jet printing device may not guarantee accurate positioning and jet printing quality of both sides of the circuit board during jet printing. Moreover, the curing system may have slow response speed, non-adjustable or narrow adjustable range of curing light intensity, which cannot meet the requirements of different jet printing materials and processes for curing conditions, affecting the adhesion, clarity and other performances of jet printed characters.

[0010] 4. Low integration level:

[0011] Many jet printing machines do not organically integrate feeding belt, discharging belt, mechanical arm assembly, jet printing device and the like, resulting in large equipment space occupation, and difficulty in information interaction and cooperative work between different components. At the same time, it cannot be controlled and capacity superimposed by a unified control system such as PLC or MES system, which is not conducive to large -scale production and management.

[0012] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content
