Description

Repairing device for inkjet printer heads {Repairing Apparatus for Inkjet Printer}

The present invention relates to a repair device for an inkjet printer head, and in particular, the nozzle head of the inkjet printer head is combined with a washing bath in the form of an open top, and then the printer head is supplied to the washing tank so that the printer head is washed in the washing tank. Due to this, it is possible to efficiently clean the inside of the nozzle without damaging the structure of the nozzle, as well as to shorten the cleaning time to repair the inkjet printer, which is caused by the clogging of the ink. It is about the device.

Inkjet printing (inkjet printing) is a solution process technology that proceeds while discharging the chemical solution out of the nozzle by applying an electrical signal to the actuator at the nozzle end of the inkjet print head.

For reference, the inkjet print head can be classified into two methods according to the following, depending on the ejection mechanism of ink droplets.

One is a heat-driven inkjet print head that generates a bubble in ink using a heat source and discharges a chemical liquid by the expansion force of the bubble.

And the other is the piezoelectric drive type inkjet print head 1 using piezoelectric elements 30 and piezo as shown in FIG. 1. This is a method of discharging the chemical liquid to the plurality of nozzles 20 by the pressure applied to the ink by the deformation of the piezoelectric element 30 to proceed the process.

The piezoelectric drive type inkjet print head 1 has been widely used in recent years. In any method, the inkjet printing technology has excellent film uniformity and film quality among thin film forming technologies based on various solution processes for forming a thin film, and is fine. It is known that the solution volume control of the unit (pico liter) is possible, so that the chemical solution consumption is very small compared to the conventional spin coating method. For this reason, the inkjet print head 1 of FIG. 1 has already been widely applied to display manufacturing fields such as LCD and OLED, and the proportion is expected to be further expanded in the future.

On the other hand, the inkjet print head 1 of FIG. 1, which is a key component part of the inkjet printing technology, has multiple nozzles 20, that is, multiple nozzles 20, as described above. In FIG. 1, only five nozzles 20 are shown for convenience.

Recently, by arranging the nozzles 20 as well as the adiabatic arrangement method, products in which one inkjet print head 1 is composed of approximately 1000 or more fine nozzles 20 are commercially available.

As described above, using the multiple nozzles 20 of the inkjet print head 1 can significantly reduce the process time, thereby improving the mass productivity of the manufacturing process.

However, the inkjet printing technology is a method of discharging the chemical liquid through the nozzle 20 of the inkjet print head 1, that is, the nozzle 20 having an extremely fine size of a few micrometers, so that the nozzle according to the chemical liquid properties ( 20) has a problem in that clogging can occur frequently.

If a clogging phenomenon occurs in one or several of the nozzles 20, a defective chemical solution may be discharged, and the uniformity or quality of the film will inevitably deteriorate. For example, when a clogging phenomenon occurs in the central nozzle 20 in FIG. 1, since the discharge of the chemical liquid through the corresponding nozzle 20 cannot proceed normally, the uniformity or quality of the entire film is inevitably deteriorated.

Let's look at this in more detail. The viscosity range of the chemical solution supported by the conventional inkjet print head 1 shown in FIG. 1 is about 8 cP to 30 cP. Because of these conditions, most of the volatile solutions are jetted.

The volatile solvent evaporates at the distal end of the fine nozzle 20. At this time, when the solvent evaporates, the solid content may remain at the distal end of the nozzle 20 or inside the nozzle 20. In FIG. 1, the central nozzle 20 corresponds to a case in which a solid form remains at its distal end.

When the clogging phenomenon of the nozzle 20 occurs in the inkjet print head 1, a printing defect, particularly a printing defect such as a line mura, may occur, which may result in a decrease in film uniformity and overall print quality. have. Therefore, in order to solve this problem, the industrial inkjet printing system is applying various types of nozzle cleaning devices (or units).

A brief description of the nozzle cleaning apparatus according to the prior art. For reference, the nozzle cleaning apparatus according to the prior art can be largely classified into a contact nozzle cleaning apparatus, a cleaning liquid immersion nozzle cleaning apparatus, and an ultrasonic nozzle cleaning apparatus.

First, as a conventional contact type nozzle cleaning device, a blotting unit and a blading unit may be mentioned.

First, the blotting unit has a method of directly wiping the surface of the inkjet print head 1 where the end of the nozzle 20 is disposed using a wiper made of a clean material. Since the blotting unit is a contact-type cleaning method, it may cause damage to the structure of the micro-nozzle 20 in its structure, and it causes a problem that the removal of solids inside the nozzle 20 is substantially impossible.

Next, the blade unit has a method of removing residual chemicals by directly scratching the surface of the inkjet print head 1 with a separate blade. This blade unit is also a method of cleaning while directly contacting the nozzle 20 like the blotting unit, which can cause damage to the structure of the fine nozzle 20 and also eliminate the problem of removing solids inside the nozzle 20. Occurs. In addition, the blade unit may cause additional problems that particles generated during the operation of the blade may be introduced into the nozzle 20.

Second, a dipping unit may be exemplified as an existing cleaning liquid immersion nozzle cleaning device. The dipping unit has a method in which the inkjet print head 1 is directly immersed in a bath containing a cleaning liquid to clean.

Since the dipping unit is only immersed in the cleaning liquid, there is a limitation in removing solids inside the nozzle 20, and it may take a long time for cleaning to cause productivity reduction due to equipment shutdown.

In addition, when dipping for a long time, it may cause additional problems that the cleaning liquid may flow into the nozzle 20.

Third, an ultrasonic cleaning unit may be used as a conventional ultrasonic nozzle cleaning device. The ultrasonic cleaning unit is a method in which the surface of the ink jet print head 1 is cleaned by dipping the ink jet print head 1 in a cleaning solution and then applying ultrasonic waves.

However, it is known that such an ultrasonic cleaning unit is not well recommended because it may cause damage or destruction of the structure of the fine nozzle 20 depending on the material and processing method of the inkjet print head 1. In addition, there is a concern that the temperature of the chemical liquid may increase during the ultrasonic cleaning operation, and thus the use thereof is limited.

As described above, in the case of the conventional method for cleaning the inkjet print head 1, that is, in the case of the contact type, the cleaning chemical immersion type, and the ultrasonic type, it causes damage to the structure of the fine nozzle 20 or the solid content inside the nozzle 20 The nozzle may be different from the conventional cleaning method in that it may not be easy to remove and also causes various problems such as impurities flowing into the nozzle 20 or excessively time-consuming cleaning operations. It is necessary to develop technology to effectively clean 20).

Looking at the components of the inkjet head repair apparatus of the present invention, the washing tank 100, the washing liquid inlet hole 110, the washing liquid withdrawal hole 120, the connecting hose 210 for the washing liquid inlet, and the connecting hose for taking out the washing liquid (220), a repeater (200) for entering and exiting the washing liquid, a connecting hose (230) for introducing the repeater, a connecting hose (240) for outputting the repeater, a pressure control valve (300), and a book valve (400) for introducing the washing liquid , Washing liquid output valve 500, airtight packing 130, washing tank assembly part 600, washing tank case 610, washing tank support 620, one-touch coupling means 630, and printer head It consists of (900).

The washing tank 100 is made of a rectangular parallelepiped container with an open top, a print head is connected through the open top, a space inside, and a print head cleaning liquid can be temporarily stored in the space. That is, the washing tank provides a space portion in which the cleaning liquid for cleaning the print head can stay for a certain period of time, and the cleaning liquid is introduced into the space portion to wash foreign substances present in the print head.

The washing liquid inlet hole 110 is formed at regular intervals on the bottom surface of the washing tank and induces that the washing liquid supplied from the outside passes to fill the washing liquid with the space of the washing tank. That is, the cleaning liquid inlet hole exists in the form of drilling a hole in the bottom surface of the cleaning tank, but may be configured in a circular, elliptical, or polygonal shape and induces the liquid cleaning solution to pass freely and enter the cleaning tank, and an embodiment of the present invention Shows the inlet hole in a circular shape for the most widely used and easy to manufacture.

The washing liquid extraction holes 120 are formed at regular intervals on the bottom surface of the washing tank, but are staggered between the washing liquid introduction holes to induce a plurality of washing liquid contained in the space of the washing tank to be output to the outside. That is, the cleaning liquid extraction hole exists in the form of drilling a hole in the bottom surface of the cleaning tank, but can be configured in a circular, elliptical or polygonal shape, and induces the liquid cleaning solution to pass freely and escape from the cleaning tank to the outside. In the example, a circular drawing-out hole is illustrated to be the most widely used and easy to manufacture.

The connecting hose 210 for the washing liquid inlet is connected to the washing liquid inlet hole and serves as a passage when the external washing liquid enters through the washing liquid inlet hole. That is, the connecting hose for introducing the washing liquid is fitted into the washing liquid inlet hole and serves as a passage through which the washing liquid can be easily supplied from outside. It is connected by using a rubber material or a flexible structure material, so that the liquid washing liquid flows freely. While helping to enter the washing tank.

The connecting hose 220 for withdrawing the washing liquid is connected to the washing liquid withdrawing hole and serves as a passage when the washing liquid contained in the washing tank is taken out through the output hole for washing. That is, the connecting hose for withdrawing the washing liquid is fitted into the washing liquid extraction hole and serves as a passage through which the washing liquid can be easily discharged to the outside. It is connected using a rubber material or a flexible structured material. It helps to withdraw from the washing tank while flowing.

The repeater 200 for input and output of the washing liquid is formed in a polyhedron shape, and a connecting hose for cleaning agent input and a connecting hose for cleaning agent are combined on the output side to form a plurality of passages therein to relay the input and output of the washing liquid. That is, the repeater for the input and output of the washing liquid is a structure of a hard material, and is formed by forming passages of various passages therein, and the liquid washing liquid is input through one of the flow paths, and the liquid flows through the other of the flow paths from the other flow paths. It is relayed so that the washing liquid of the product is output. In other words, the input or output of the washing liquid is made through a repeater for input and output of the washing liquid.

The connecting hose 230 for introducing the repeater is coupled to one side of the input side of the washing liquid input / output repeater, and serves as a passage for external washing liquid to enter the washing tank through the washing liquid input / output repeater. In other words, the connecting hose for the repeater is connected to one side of the repeater for the input and output of the washing liquid, and serves as a passage for facilitating the washing liquid as a repeater. It is connected by using a rubber material or a flexible structured material. This free-flowing flow helps to enter the repeater.

The connecting hose 240 for the repeater output is coupled to the other side of the input side of the repeater for the input and output of the washing liquid and serves as a passage so that the washing liquid contained in the washing tank is output to the outside through the repeater for the input and output of the washing liquid. In other words, the connecting hose for the withdrawal of the repeater is fitted to the other side of the repeater for input and output of the washing liquid and serves as a passage for facilitating the washing liquid as a repeater. It helps to withdraw from the repeater while flowing freely.

The pressure control valve 300 is installed on one side of the repeater for the input and output of the washing liquid, but controls the width of the passage on the output side of the washing liquid to control the output amount when the washing liquid is output from the washing tank. That is, it is possible to induce the washing liquid to remain for an appropriate time according to the degree of contamination of the print head by adjusting the output level of the washing liquid provided in the washing tank to control the time the washing liquid stays in the washing tank. That is, when the contamination level of the print head is high, the cleaning fluid is lowered to lower the output pressure so that the cleaning fluid moves for a long time to keep the cleaning fluid in the cleaning bath, and when the contamination of the print head is low, the cleaning fluid quickly remains in the cleaning bath for a short time. Increase the output pressure of the washing liquid so that the washing liquid moves quickly.

The washing liquid inlet valve 400 is installed at the end of the repeater inlet connection hose and serves to block the external washing liquid from flowing back in the opposite direction when passing through the repeater inlet connection hose. That is, the inlet valve for washing liquid is not to flow back to the outside when the external washing liquid is introduced into the repeater. If the inlet valve for washing liquid does not exist, the washing liquid flowing into the repeater may escape to the outside and contaminate the work place. There will be. Accordingly, in the present invention, by installing a check valve for introducing the washing liquid, it is possible to increase the workability by preventing the washing liquid provided to the washing tank from flowing back.

The washing liquid output check valve 500 is installed at the end of the repeater output connection hose and serves to prevent the washing liquid from flowing back in the opposite direction when the washing liquid is discharged to the outside through the repeater output connection hose. That is, since the washing liquid flowing out into the washing tank has a directivity to be output to the outside, it is prevented from flowing back into the washing tank to prevent the external liquid from flowing back and contaminating the print head.

The hermetic packing 130 is installed on the upper rim of the washing tank, and serves to prevent the washing liquid from flowing out by allowing the print head and the washing tank to be sealed when they are combined. In other words, when the print head and the washing tank are combined, the airtight packing works to ensure strong adhesion to each other, thereby preventing the washing liquid from escaping into the coupling gap between the print head and the washing tank, thereby preventing the workplace from being contaminated.

The washing tank assembly part 600 includes a washing tank case 610, a washing tank support 620, and one-touch coupling means 630.

The washing tank assembly case 610 is a means for fixing the washing tank by placing it thereon, thereby maintaining a stable fixing state without flowing the washing tank. In other words, since the case for assembling the washing tank stably seats the washing tank, there is no need to fix the washing tank separately, and if the case for assembling the washing tank is combined with the print head, the print head can be automatically brought into contact with the washing tank, and thus exists in the washing tank The cleaning liquid to be contacted with the print head can remove contaminants.

The washing tank support 620 has a rectangular parallelepiped shape and is located on both sides of the lower side of the washing tank assembly case to induce the washing tank assembly case to stand upright while maintaining a stable posture. That is, the washing tank support is located at the bottom of the washing tank assembly case, but is located on both sides to firmly support the washing tank assembly case and help to stand stably.

The one-touch coupling means 630 is installed on one end of the washing tank case and combines the print head and the washing tank to induce mutual coupling with one touch. That is, the one-touch coupling means combines the print head and the cleaning tank at a time to maintain a stable state, and releases the print head and the cleaning tank by removing them at once if necessary.

Looking at the assembly method of the present invention as follows.

First, the present invention is provided with a washing tank 100, the washing tank is made of a rectangular parallelepiped-shaped container with an open top, and at this time, a plurality of holes are formed at the bottom of the washing tank to form a washing tank inlet hole 110 at regular intervals. ), And is formed by intermittently forming a washing liquid extraction hole 120 between the washing tank introduction holes.

The washing liquid inlet hole 110 and the washing liquid outlet hole 120 are preferably formed by a drill, because the material of the washing tank is basically iron, such as aluminum. That is, the washing tank uses a material such as stainless or aluminum that does not rust, and above all, should not be damaged by the washing liquid.

As described above, in the washing tank 100 applied to the present invention, a washing tank inlet hole 110 and a washing tank outlet hole 120 are previously formed, and the washing tank inlet hole 110 has a connection hose 210 for washing liquid inlet. One side is coupled, and one side of the connecting hose 220 for withdrawing the cleaning liquid is coupled to the cleaning liquid extraction hole 120.

The connecting hose 210 for the washing liquid inlet and the connecting hose 220 for the washing liquid can be bent freely because they are flexible rubber materials.

Connect the one side of the repeater 200 for entering and exiting the washing liquid, respectively, to the other side of the connecting hose 210 for connecting the washing liquid and the connecting hose 220 for withdrawing the washing liquid, and the other side of the repeater 200 for entering and removing the washing liquid is connected to the repeater. Connect the hose 230 and the connecting hose 240 for repeater output, respectively. The connection hose 230 for the relay input and the connection hose 240 for the relay output can also be flexed freely because they are flexible rubber materials.

In addition, the end of the connecting hose 210 for the repeater inlet and the connecting hose 220 for the repeater output are assembled with a washing valve 400 for washing liquid inlet and a washing valve 500 for washing liquid, respectively, and assembly of the washing tank is completed. .

Hereinafter, the effect of the present invention will be described.

First, at the bottom of the washing tank 100, a washing liquid inlet hole 110 and a washing liquid withdrawal hole 120 are formed, and the washing liquid inlet hole 110 and the washing liquid withdrawal hole 120 respectively have a connecting hose 210 for introducing a washing liquid. ), And the connecting hose 220 for the withdrawal of the cleaning agent is connected, the connecting hose 210 for drawing the cleaning solution, and the repeater 200 for the introduction of the cleaning solution is connected to the connecting hose 220 for withdrawing the cleaning solution, and the cleaning solution A connection hose 230 for relay input and a connection hose 240 for relay output are connected to the repeater 200 for entering and exiting, and a pressure control valve 300 is installed at one end of the repeater 200 for entering and exiting the cleaning agent, The connection hose 230 for the repeater inlet and the connection hose 240 for the repeater output are in a state in which the shut-off valve 400 for drawing the washing liquid and the shut-off valve 500 for outputting the washing liquid are connected, respectively.

An airtight packing 130 is installed on the top of the washing tank 100, and the washing tank 100 is assembled to the washing tank case 610, and washing tank supports 620 are provided at both lower ends of the washing tank case 610. It is installed, and the one-touch coupling means 630 is coupled.

After the assembly is completed as described above, the printer head 900 is detached to face the washing tank 100, and then the printer head 900 and the washing tank 100 are mutually coupled with one-touch coupling means 630.

Thereafter, the washing liquid is supplied through the inlet valve 400 for introducing the washing liquid.

Then, the washing liquid provided through the washing valve 400 for introducing the washing liquid is delivered to the repeater 200 for the washing liquid input and output through the connecting hose 230 for the repeater input, and thereafter the connecting liquid 230 for the washing liquid input and the washing liquid input hole It is supplied to the washing tank through (110).

When the supply of the washing liquid to the washing tank 200 is completed, the washing liquid contacts the contact surface of the printer head 900 and washes the contaminants of the printer head 900.

And, after a certain period of time, since the washing liquid is melted from the contaminants generated in the print head 900, the supplied washing liquid is contaminated. At this time, the washing liquid is withdrawn to the book valve 500 for drawing out the washing liquid to circulate the contaminated washing liquid. The cleaning device is combined, and the cleaning solution is slowly discharged using the cleaning device extraction device.

At this time, looking at the path through which the washing liquid escapes, the washing liquid withdrawal hole 120, the connecting hose 220 for withdrawing the washing liquid, the repeater 200 with the washing liquid inlet, and the connecting hose 240 for withdrawing the washing liquid and the book valve 500 for withdrawing the washing liquid ), And the washing liquid escapes.

As described above, when the washing liquid is discharged to the outside, it is gradually circulated while supplying the washing liquid. At this time, the pressure control valve 300 is appropriately adjusted to facilitate the washing of the printer head 900 as the washing liquid is gradually drained out rather than rapidly exiting. To proceed.

On the other hand, the book valve for outputting the washing liquid serves to prevent external contaminants from penetrating into the washing tank, and discharges the washing liquid inside the container to the outside of the washing tank. The washing liquid output unit 10 and the washing liquid passing means 20 And a temporary blocking ball 30, a cleaning liquid input unit 40, and a blocking ball guide means 50.

The washing liquid output unit 10 is formed of a first washing liquid flow pipe 11 through which washing liquid passes on one side, and a first coupling pipe 12 formed on the other side.

The washing liquid passing means 20 is inserted into the first coupling pipe of the valve for the washing liquid flow, and the circular ring 21 having a diameter smaller than the inner diameter of the first coupling pipe and the inner side of the circular ring are formed. It consists of a projection 22 and a hole 23 for the flow of washing liquid formed between the projections.

The washing liquid input unit 40 is formed on one side of the second coupling pipe 42 coupled to the inside of the first coupling pipe 12 of the washing liquid output unit 10, and the second washing liquid flow pipe through which the washing liquid passes on the other side. (41) is formed.

The temporary blocking ball 30 is coupled inside the second cleaning liquid flow pipe 41 and temporarily coupled to the bypass disk 20 so that the cleaning liquid flows through the first cleaning liquid flow pipe 11 of the cleaning liquid output 10. Induces to flow, or acts as a temporary coupling to the inlet of the second washing liquid flow pipe 42 of the washing liquid input unit 40 to block the penetration of contaminants through the second washing liquid flow pipe 42.

The blocking ball guide means 50 is installed at a certain interval inside the second coupling tube, and serves to guide the temporary blocking ball to move naturally left and right without departing from the horizontal center of the second coupling tube.

Looking at the operation of the present invention made as described above is as follows.

First, looking at the process of interrupting the flow of the washing liquid, as shown in FIGS. 4A, 4B, and 4C, external contaminants are introduced through the first washing liquid flow pipe 11 of the washing liquid output unit 10.

Thereafter, the second temporary blocking ball 30 is pushed out, and at this time, the second temporary blocking ball 30 moves along the blocking ball guide means 50.

Thereafter, the second temporary blocking ball 30 is further pushed to close the inlet of the second washing liquid flow pipe 42 of the washing liquid input unit 40.

Then, contaminants penetrating through the washing liquid output unit 10 do not pass through the washing liquid input unit 40 and are intermittent.

Second, looking at the process of generating the flow of the washing liquid, as shown in FIGS. 5A, 5B, and 5C, it is introduced through the second washing liquid flow pipe 42 of the washing liquid input unit 40.

Thereafter, the second temporary blocking ball 30 is pushed out, and at this time, the second temporary blocking ball 30 moves along the blocking ball guide means 50.

Thereafter, the second temporary blocking ball 30 is further pushed to be in close contact with the inlet of the washing liquid passing means 20 coupled to the washing liquid output unit 10.

Then, the washing liquid flowing through the washing liquid input unit 40 flows between the second temporary blocking ball 30 and the washing liquid flow hole 22 of the washing liquid passing means 20.

In addition, the number of blocking ball guide means 50 is preferably about 3 to 5, and at least 3 is preferably installed.

In addition, the reason for limiting the number of blocking ball guide means 50 to 5 or less is that as the number of blocking ball guide means 50 increases, the temporary blocking ball 30 may move more naturally, but the flow of the washing liquid is prevented. When generated, the washing liquid must flow between the blocking ball guide means 50, because when a large number of blocking ball guide means 50 is present, the flow of the washing liquid is blocked.
