Referring to fig. 1, an inkjet printing apparatus 100 according to an embodiment of the present disclosure includes a nozzle module 10, a holder 20, and a plasma processing module 30. The nozzle module 10 moves along the printing direction, the bracket 20 is connected to the nozzle module 10, the plasma processing module 30 is disposed on the bracket 20 and located on one side of the nozzle module 10 along the printing direction, and the plasma processing module 30 is used for performing hydrophilic processing on the member to be printed 200.
So plasma treatment module 30 and shower nozzle module 10 are connected through support 20, so can drive plasma treatment module 30 simultaneously and remove when shower nozzle module 10 moves along printing the direction, and because plasma treatment module 30 is in the place ahead of shower nozzle module 10, the integrated level is high, and treat at plasma treatment module 30 and print component 200 and clean the back, shower nozzle module 10 can be quick simultaneously and carry out the inkjet to this region after cleaning and print, and then make surface treatment technology and printing technology can seamless joint, the real-time and the high efficiency of process have been guaranteed, and improve the rete cohesion, in order to improve the printing effect.
It should be noted that the holder 20, the showerhead module 10 and the plasma processing module 30 can be detachably connected by screws or fasteners, so as to facilitate subsequent repair and replacement. The bracket 20 may be made of metal material to ensure the stability of the connection and the support of the bracket 20. And the member to be printed 200 is a substrate or the like. The plasma processing module 30 utilizes the properties of the active components to process the surface of the sample by applying sufficient energy to the gas to ionize the gas into a plasma state, thereby achieving the purpose of cleaning and modifying the printing surface of the member to be printed 200, such as reducing the water drop angle, and improving the film bonding force.
Referring to fig. 1 and 2, in some embodiments, the plasma processing module 30 includes a first plasma processor 31, a second plasma processor 32, and a third plasma processor 33, and each of the first plasma processor 31, the second plasma processor 32, and the third plasma processor 33 is detachably connected to the rack 20. The first plasma processor 31 is used for performing hydrophilic treatment on the region to be printed 201 of the member to be printed 200, and the second plasma processor 32 and the third plasma processor 33 are used for performing hydrophobic treatment on both sides of the region to be printed 201 of the member to be printed 200.
In order to solve the technical problem that the edge saw teeth at the printing position are difficult to control, the plasma processing module 30 is composed of a first plasma processor 31, a second plasma processor 32 and a third plasma processor 33, so that the first plasma processor 31 can perform hydrophilic processing on the region 201 to be printed of the component 200 to be printed, and meanwhile, the second plasma processor 32 and the third plasma processor 33 perform hydrophobic processing on two sides of the region 201 to be printed on the component 200 to be printed, namely, the water drop angle is increased, so that the printing ink is better limited in a required printing area, the edge straightness of spreading of the ink is improved, and different ink printing requirements and different substrate printing process requirements can be more easily met. It should be noted that the first plasma processor 31, the second plasma processor 32 and the third plasma processor 33 are the same structure, so as to facilitate installation, and thus, the three can have hydrophilic or hydrophobic effects by using different gas sources and different energies. In addition, the first plasma processor 31, the second plasma processor 32 and the third plasma processor 33 can be connected in advance to form an integral module, and then the integral module is connected to the bracket 20, so that the integral installation and disassembly are convenient. Of course, the first plasma processor 31, the second plasma processor 32 and the third plasma processor 33 can be detachably connected to the bracket 20 separately, so as to be convenient for subsequent maintenance and replacement separately, which can be selected by those skilled in the art according to specific situations.
Further, the first plasma processor 31 is disposed to be offset from the second plasma processor 32 and the third plasma processor 33 in the printing direction. In order to reduce interference between hydrophilic interaction and hydrophobic interaction between the first plasma processor 31 and the second plasma processor 32 and the third plasma processor 33, the first plasma processor 31 and the second plasma processor 32 and the third plasma processor 33 are arranged in a staggered manner along the printing direction, so that the first plasma processor 31 has a gap with the second plasma processor 32 and the third plasma processor 33 respectively, and therefore hydrophilic interaction between the first plasma processor 31 and the second plasma processor 32 and the third plasma processor 33 and hydrophobic interaction between the second plasma processor 32 and the third plasma processor 33 are guaranteed.
Furthermore, the bracket 20 includes a first connection section 21, a second connection section 22 and a third connection section 23, the first connection section 21 and the second connection section 22 are connected to the nozzle module 10, and two ends of the third connection section 23 are respectively connected to one end of the first connection section 21 far away from the nozzle module 10 and one end of the third connection section 23 far away from the nozzle module 10 in a bending manner; the first plasma processor 31 is connected to a side of the second connection section 22 away from the showerhead module 10, and the second and third plasma processors 32 and 33 are connected to a side of the second connection section 22 toward the showerhead module 10.
Wherein, the first connecting section 21, the second connecting section 22 and the third connecting section 23 are an integral structure to further ensure the structural stability of the bracket 20. And the installation efficiency is improved by disposing the first plasma processor 31 and the second plasma processor 32 and the third plasma at opposite sides of the second connection section 22, respectively, so as to facilitate the respective disposition of the first plasma processor 31, the second plasma processor 32 and the third plasma processor 33. And the second plasma processor 32 and the third plasma processor 33 are positioned on the same straight line, so as to improve the uniformity of the hydrophobic treatment on the two sides of the region to be printed 201, and further improve the printing effect.
Further, the rack 20 further includes an adjustment structure 24, and the second plasma processor 32 and the third plasma processor 33 are connected to the third connection section 23 through the adjustment structure 24, and the adjustment structure 24 is used for adjusting the distance between the second plasma processor 32 and the third plasma processor 33. Wherein the adjustment structure 24 is arranged such that the spacing between the second plasma processor 32 and the third plasma processor 33 is adjustable to correspond to different print widths. It should be noted that the adjusting structure 24 may be formed by forming a plurality of spaced-apart abdicating holes in the bracket 20, and then fixing the second plasma processor 32 and the third plasma processor 33 to different abdicating holes by fixing screws to adjust the distance between the two types of abdicating holes, or may be directly fixed by moving the second plasma processor 32 and the third plasma processor 33 to appropriate positions and then fixing the two types of abdicating holes in a limiting manner such as a snap.
Further, the adjusting structure 24 includes a guide rail 241, the guide rail 241 is disposed on the third connecting section 23 and extends along two opposite ends of the third connecting section 23, and the second plasma processor 32 and the third plasma processor 33 are slidably connected to the guide rail 241. Through the arrangement of the guide rail 241, the second plasma processor 32 and the third plasma processor 33 can be directionally adjusted, and the moving process is smoother, so that the adjustment distance between the second plasma processor 32 and the third plasma processor 33 is more convenient, and the usability of the ink jet printing device 100 is improved.
Further, the adjustment structure 24 further includes a driving motor 242, and the driving motor 242 is connected to the guide rail 241 for driving the second plasma processor 32 and the third plasma processor 33 relatively close to or away from each other along the guide rail 241. The driving motor 242 may be a dual-rotor linear motor, so that the movement of the second plasma processor 32 and the third plasma processor 33 can be controlled simultaneously, and the movement of the second plasma processor 32 and the third plasma processor 33 is more accurate, thereby improving the intelligence.
In some embodiments, referring to fig. 1 and 2, the head module 10 includes a mounting base 11 and an inkjet head 12, a first connecting section 21 and a second connecting section 22 are connected to the mounting base 11, opposite sides of the inkjet head 12 are respectively connected to the first connecting section 21 and the second connecting section 22, and the inkjet head 12 is located on a side of the mounting base 11 facing the second connecting section 22. The mounting seat 11 can be connected to other components of the inkjet printing apparatus 100, and the mounting seat 11 is respectively connected to the first connecting section 21 and the second connecting section 22, so that the supporting force of the bracket 20 is ensured through the mounting seat 11, and the stability of the plasma processing module 30 during movement is further ensured. The opposite two sides of the inkjet head 12 are respectively fixed on the first connection section 21 and the second connection section 22, so that the second connection section 22 and the third connection section 23 can limit and fix the inkjet head 12, that is, the bracket 20 not only serves to connect the nozzle module 10 and the plasma processing module 30, but also serves to fix the inkjet head 12 of the nozzle module 10. Of course, the inkjet head 12 can also be connected to the mounting base 11 at the same time, so as to ensure the stability of the overall structure of the inkjet head 12 during movement, and further ensure the printing effect.
Alternatively, the first plasma processor 31 is a wide-width plasma processor, and the second plasma processor 32 and the third plasma processor 33 are spot plasma processors. Since the first plasma processor 31 is selected according to the width of the region 201 to be printed of the component 200 to be printed, the width of the frame printing is about 10mm, and the wide-width plasma processor can cover the width, so that the region 201 to be printed can be covered by a single printing. Since the boundaries of the hydrophilic and hydrophobic regions need to be processed more accurately, the second plasma processor 32 and the third plasma processor 33 use a wide and small spot type plasma processor for processing.

So plasma treatment module and shower nozzle module pass through the support and connect, so can drive plasma treatment module removal when the shower nozzle module moves along printing the direction simultaneously to because plasma treatment module is in the place ahead of shower nozzle module, the integrated level is high. And the plasma processing module reduces the water drop angle of the to-be-printed area of the to-be-printed component, so that the hydrophilicity of the to-be-printed area of the to-be-printed component can be improved. The nozzle module can simultaneously and quickly perform ink-jet printing on the cleaned area, so that the surface treatment process and the printing process can be in seamless connection, the real-time performance and the high efficiency of the process are guaranteed, the film binding force is improved, and the printing effect is improved.

The support can be made of metal materials so as to ensure the stability of support connection and support. And the member to be printed is a base substrate or the like. The plasma processing module applies enough energy to the gas to enable the gas to be ionized into a plasma state, and uses the properties of the active components to process the surface of the sample, thereby achieving the purposes of cleaning and modifying the printing surface of the component to be printed, such as reducing the angle of water drops, and improving the bonding force of the film layer.
Step 20: the spray head module moves along the printing direction to perform ink-jet printing on the printing area, and the spray head module drives the plasma processing module to move, so that the plasma processing module performs hydrophilic processing on the to-be-printed area of the to-be-printed component.

Meanwhile, the second plasma processor and the third plasma processor perform hydrophobic treatment on two sides of a to-be-printed area on a to-be-printed component, namely, the water drop angle is increased, so that printing ink is better limited in a required printing area, the edge straightness of ink spreading is improved, and different ink printing requirements and different substrate printing process requirements can be more easily met. It should be noted that the first plasma processor, the second plasma processor and the third plasma processor are of the same structure so as to be convenient for installation, and thus, the three can respectively have hydrophilic or hydrophobic effects by adopting different gas sources and different energies.
