Description
Technical Field
The invention relates to the technical field of aerosol ink-jet printing, in particular to a device and a method for monitoring real-time curing of aerosol ink-jet printing.
Background
The aerosol ink-jet printing technology is a new 'direct-writing' printing technology, and compared with the traditional printing technology, the aerosol ink-jet printing technology has the characteristics of high printing precision, good boundary controllability, more applicable materials, wide viscosity range, high material utilization rate, no pollution and the like. The process is considered to be a very potential printing process and has a very good commercial application prospect in the field of low-cost and high-yield printed electronics, since the process can directly form a patterned thin film without a mask. A range of applications have been explored for aerosol inkjet printing, including active and passive electronic components, actuators, and sensors, among others. Aerosol inkjet printing devices typically include an ink cartridge and an inkjet head capable of depositing a precise solution onto a design area, and when depositing a photoreactive ink, the inkjet head can be used in conjunction with a light curing device to rapidly cure the photoreactive ink, wherein the level of light curing on the ink is directly related to the accuracy and quality of the product. However, one difficulty with aerosol inkjet printing using photoreactive inks is the lack of control and real-time monitoring of the level of photopolymerization achieved during production. Although post-curing is also a common curing method, the level of polymerization can be increased after production is complete. However, the post-curing method has limitations in aerosol inkjet printing, and since aerosol inkjet printing is high-precision printing, ink that is not cured in real time during printing may cause the effect of edge loosening, thereby seriously affecting the geometric precision of the product. Therefore, the method for performing real-time Ultraviolet (UV) curing and monitoring for aerosol inkjet printing and establishing a corresponding device are of great significance for improving the effect of the photoreactive ink for aerosol inkjet printing. Wherein the effect of light curing is mainly related to the energy value of the UVLED light source, the wavelength of the light and the curing distance. For different inks, the energy provided by the light source needs to be changed by adding a real-time UV curing light source or adjusting the distance between the light source and a printing trace; in addition, to the printing trace of the high accuracy that aerosol inkjet printed the production, need monitor the visual angle through adjusting the camera lens and clearly real-time supervision printing trace appearance, if the monitoring through external display shows that printing trace is discontinuous or the appearance is not conform to the requirements the time, printing system's feedback adjustment mechanism carries out work, and the bullet window is reported to the police and is stopped printing, makes things convenient for the staff to adjust printing system as early as possible when avoiding the material extravagant. And the lens monitoring and the UV curing light source matched orientation adjustment can enable light spots formed by the UV light source to be accurately aligned with high-precision printed traces, so that the curing efficiency is improved. Not only the real-time nature of curing and monitoring of the printed traces, but also the adjustability of the apparatus and the universality of the photoreactive ink are taken into account during the process set-up and apparatus design. However, in the existing aerosol inkjet printing system, the monitoring mode of a printing line is single, the position and the number of the devices cannot be changed according to the requirements of experiments in use, and the existing aerosol inkjet printing system mostly uses a post-curing treatment mode for printing traces generated by photoreactive ink, so that the curing and monitoring of products are limited, the flexibility is poor, the real-time in-situ curing requirements of different types of ink cannot be met, and the application range of the device is limited. Therefore, the method for multidirectional real-time UV curing and feedback monitoring of the aerosol ink-jet printing trace is provided, and the device which enables the printing trace to be cured more uniformly and has higher integration level is correspondingly designed, so that the method has important significance in the subsequent development of aerosol ink-jet printing.

For the real-time lens monitoring module, firstly, a three-axis O-shaped optical adjustment lens frame 44 and a lens sleeve 45 are glued, then a lens inclined connecting rod slider 41 and a middle push platform adapter plate 42 are connected through a bolt, a one-dimensional middle push platform 43 and a middle push platform adapter plate 42 are connected through a bolt, the one-dimensional middle push platform 43 and the three-axis O-shaped optical adjustment lens frame 44 are also connected through a bolt, the lens inclined connecting rod slider 41 can freely slide in a circular track module 1, after the lens inclined connecting rod slider 41 slides to a target position, the lens inclined connecting rod slider 41 is tightly propped against the inner wall of the circular track module 1 through a bolt, the lens inclined connecting rod slider 41 is fixed on the circular track module 1, a compact telecentric lens 46 can be vertically adjusted in the lens sleeve 45, and after the position meets the focal length requirement, the compact telecentric lens 46 is tightly propped against the lens sleeve 45 through a bolt, and the compact telecentric lens 46 and the lens sleeve 45 are relatively fixed.
For the circular track module 1, before installation, the corresponding number of the light-curing modules and the lens real-time monitoring modules which can meet the experimental requirements are matched with the circular track module 1, and then the circular track module 1 is fixed on the adapter plate module 2 through bolts.
For the adapter plate module 2, the adapter plate module 2 is fixed on the motion platform using bolts.
After the experimental setup is completed, it is mounted on the motion stage and a compact telecentric lens 46 is connected to a computer to view the printed real-time trace images, as shown in fig. 8.
Firstly, taking nano silver ink as an example, adjusting the carrier gas flow of a printing system to be 20sccm, the sheath gas flow to be 30sccm, the atomization voltage to be 20v, and the printing speed to be 0.5mm/s, wherein the observed experimental result is good, the real-time printing effect is continuous, the error is kept in a set range, and the system has no popup window alarm and printing pause phenomena, as shown in fig. 9.
Secondly, adopting dielectric resin ink, adjusting the air carrying quantity of the printing system to be 30sccm, the sheath gas to be 40sccm, the atomization voltage to be 40v, the printing speed to be 0.5mm/s, observing that the experimental result can not meet the requirement, the printing trace is uneven in shape, and the system pops the window to alarm and stops printing, as shown in fig. 10 and 11.
And after the popup is alarmed, the system suspends printing, and if the 'system parameter adjustment' is selected, the printing parameters can be adjusted and then the printing is restarted, so that the waste of material and time cost is avoided. In the pre-experiment period, a stage with an unsatisfactory printing effect inevitably occurs, but the stage does not need system popup alarm and pause printing, after the system pauses printing and pops up the popup alarm for the first time, "continues printing" is selected, and popup alarm is not performed on the condition that a print line is not ideal again in the current printing stage until a working path set in the initial printing stage is completed, so that the early observation of the pre-experiment is met.
The invention provides a device which is simple in structure, easy to operate, capable of monitoring a printed trace line in real time at multiple angles, performing feedback adjustment and performing multi-directional uniform real-time UV curing on the trace line. The requirements under different conditions are met by carrying out multidirectional real-time adjustment on the curing light source and the monitoring lens, so that the curing efficiency is improved, the real-time monitoring target is achieved, and the curing light source and the monitoring lens are effectively integrated with the existing system. The device of the invention has the following characteristics as a whole:
(1) The equipment is easy to disassemble and assemble, and has good adaptability to different types of photosensitive ink. The integrated design thinking is used, the monitoring feedback function and the curing function are integrated on the same device, so that the device is more compact and is convenient to assemble and disassemble. Different curing and monitoring feedback requirements can be met by moving or adding the sliding blocks corresponding to different functions, and different functional printing inks can be adapted by adjusting the curing module and the monitoring module. The problem of current aerosol inkjet printing equipment to beating the inhomogeneous, single to beating the trace line monitoring visual angle of seal line solidification is solved.
(2) The device is simple to operate and easy to operate, and alignment of curing and monitoring of the printed trace after the device and the printing spray head are assembled is easy to guarantee. The design is that the position of a sliding block with corresponding functions is determined by sliding in a circular track, a threaded hole is formed in the sliding block, the track and the sliding block are fastened and connected by using a bolt after the sliding block slides to the determined position, and the position of the sliding block is fixed in the printing process, so that the real-time, accurate and stable curing and monitoring of a product are ensured in the printing process; the circular track ensures that the curing light source and the monitoring lens can be always aligned with the position of a product on the printing substrate in the sliding process of the functional slider.
(3) The feedback adjustment avoids the waste of material and time cost, improves the printing quality and has positive effect on the manufacture of precise structures. Due to the instability of aerosol ink-jet printing equipment, the situation that a printing trace is not communicated or the appearance of the printing trace is not ideal inevitably occurs in the process of printing the trace, but for the micron-order printing trace, the appearance change of the printing trace is difficult to see by naked eyes, and for long-time printing work, a worker cannot guarantee the working state of the monitoring system at any moment, so that the lens real-time monitoring module carries out real-time monitoring feedback on the printed trace according to the appearance state of the trace set before printing, and if the monitoring trace is discontinuous or the appearance of the printed trace does not meet the preset setting, the system stops working and carries out popup alarm, and the worker can conveniently adjust in time.
