Problems solved by technology

However, when the thickness of the mold layer is lower than a certain level, during the process of clamping the mold layer, the mold layer is too thin to withstand the force of clamping, so that bending occurs, resulting in the failure of normal coating. glue
Even if the above-mentioned bottom-thick mold layer is placed flat on the machine and the substrate is attached, because the substrate itself is an opaque material, it is difficult to align the ink chamber and the drive device.
Also, re-clamping a lay-flat ply can damage the ply itself
Therefore, the thinning of current inkjet printheads has great limitations

Abstract

The invention discloses a manufacturing method of a thin-type ink-jet printing head. The manufacturing method comprises the steps that a plastic mold layer is formed, the plastic mold layer is provided with a first surface and a second surface which are opposite to each other, a spray hole is formed in the first surface, an ink chamber is formed in the second surface, and the spray hole communicates with the ink chamber; an adhesive reducing layer and a transparent support plate are sequentially arranged on the first surface, and thus the plastic mold layer is adhered to the transparent support plate; after the transparent support plate is clamped, glue is applied on the second surface, and the plastic mold layer is pasted on the side, provided with a driving device, of a substrate; and the viscosity of the adhesive reducing layer is reduced, and the adhesive reducing layer is stripped off the transparent support plate. The invention discloses a device for achieving the manufacturing method. According to the manufacturing method, the technical problems existing in the thinning process of the ink-jet printing heat are solved.

Description

technical field [0001] The invention relates to the technical field of inkjet printers, in particular to a manufacturing method capable of releasing the thickness limitation of a thin inkjet printing head. Background technique [0002] The inkjet print head is one of the core components in the inkjet printer, such as figure 1 As shown, it includes a nozzle hole a and an ink chamber b communicating with the nozzle hole, and a driving device c is also arranged in the ink chamber. The role of the driving device c is to provide energy to the ink in the ink chamber b, so that the ink can be ejected at a certain speed through the nozzle a. [0003] The method usually used in the process of making inkjet printheads at present is the bonding method. Such as figure 2 As shown, the bonding method is to use the injection molding process to form the mold layer d having the structure of the nozzle hole a and the ink chamber b, and then attach the mold layer d to the substrate e on wh...
