Description

  The present invention relates to an ink jet recording apparatus that performs a recording operation by discharging a liquid such as ink, and an ink jet recording head used in the recording apparatus. The present invention can be applied to a general printing apparatus, a copying machine, a facsimile having a communication system, an apparatus such as a word processor having a printing unit, or a multifunction recording apparatus combining these apparatuses. In particular, the present invention is suitably applied to a recording apparatus that performs high-speed and high-quality printing.
  Conventionally, an inkjet recording apparatus is low in running cost, can be downsized, and can easily support color image recording using a plurality of colors of ink. Widely used and commercialized.
  On the other hand, as an energy generating element that generates energy for ejecting ink from the ejection port of the recording head, an element that uses an electromechanical transducer such as a piezo element, or an electromagnetic wave such as a laser emits heat to generate heat. There are those that discharge ink droplets by the action of, and those that heat a liquid by an electrothermal conversion element having a heating resistor.
  Among them, an inkjet recording system head that uses thermal energy to eject ink droplets can arrange discharge ports at high density, and therefore can perform high-resolution recording. Recording heads that use electrothermal transducers as energy generating elements are also available in smaller sizes, and are sufficient for the advantages of IC technology and micromachining technology that have made significant progress in technology and improved reliability in the recent semiconductor field. This is advantageous because it can be used in high density, easy to mount with high density, and inexpensive to manufacture.
  In addition, in order to perform printing with higher definition, a method of creating a nozzle for ejecting ink with high accuracy using a photolithographic technique has been used.
  Recently, in order to realize high-definition image recording at a higher speed, it is desired to realize a recording head having a longer print width. Specifically, a head having a length of 4 inches to 13 inches or the like has been required.
  As the head becomes longer and faster in this way, the energy input to the head increases, and as the head temperature rises during printing, a temperature distribution in the length direction of the head occurs. The reason why the temperature distribution occurs in the length direction is that the temperature of the ink supplied to the common liquid chamber rises when it comes into contact with the recording element substrate heated by the recording element heat. When the recording element substrate is integrally arranged in the longitudinal direction of the liquid chamber, or when a plurality of recording element substrates are arranged in the longitudinal direction, the ink temperature rises as the ink moves downstream, and from the upstream side The downstream temperature increases. This causes problems in printing reliability, such as a difference in ejection amount in the head length direction within the page, unstable ejection at high temperatures, and deterioration in continuous printability, and some measures are required. In particular, when an image is recorded by a single scan for the purpose of speeding up, image deterioration becomes remarkable.
  Conventionally, proposals for cooling the head with airflow from circulating water or a fan have been publicly known against image deterioration and non-ejection due to head temperature rise. Patent Document 1 describes that a groove is formed on a side opposite to a heating element of a heating plate of a recording head, and a cooling medium is circulated through a flow path formed by adhering a sealing plate. Patent Document 2 describes that the head is air-cooled by providing a fan.
Although the above invention is effective from the viewpoint of cooling the entire head, since the temperature difference in the head length direction has not been considered at all, the change in the ejection amount in the head length direction cannot be suppressed, and the high It could not meet the demands for higher image quality and higher speed.
Japanese Patent Registration No. 2889360 JP 2002-248746 A
  In order to satisfy the demands for high speed and high image quality, the conventional head suppresses the temperature rise in the head and the temperature distribution in the longitudinal direction of the head, which has occurred due to the advancement of the length and density of the head. I could not. Therefore, it was not possible to satisfy both demands for higher speed and higher image quality. Reducing the head temperature and reducing the distribution is an issue for high speed and high image quality.
  SUMMARY OF THE INVENTION In view of the above-described problems of the prior art, an object of the present invention is to provide a head with high print reliability while satisfying the requirements for high speed and high image quality.
  In order to achieve the above object, an ink jet recording head according to the present invention has a flow path separately from an ink flow path in the vicinity of a recording element substrate on which a plurality of nozzles for discharging liquid and a plurality of recording elements for generating discharge energy are arranged. And cooling the entire recording head by flowing a cooling medium from the opposite side of the flow direction of the ink flowing in the common liquid chamber, and reducing the temperature distribution in the length direction of the head. To do.
  As specific places where another flow path is provided, the inside of the recording element substrate support plate and the common liquid chamber can be raised, but in addition to this, the temperature distribution is suppressed by suppressing the temperature rise of the ink flowing in the common liquid chamber. There is no problem if the configuration can reduce the above.
  Further, water, ink, air, nitrogen, or the like can be used as the cooling medium flowing through the flow path, and liquid media such as water and ink are particularly excellent from the viewpoint of cooling efficiency. In addition, it is more effective to circulate these media through a device having a temperature control function while circulating the temperature.
  As described above, according to the present invention, the flow of the cooling medium is formed from the opposite side of the ink flow direction in the common liquid chamber of the inkjet recording head, and the flow of ink supplied to the recording element substrate is caused by flowing the cooling medium. The path and the recording element substrate are cooled and the temperature distribution is reduced. This makes it possible to suppress and control the rise in the head temperature due to the high speed and high density of printing, and to achieve both high speed and high image quality and greatly improve the reliability in continuous printing.
  Next, embodiments of the present invention will be described with reference to the drawings.

The recording element substrate support plate H1200 has an X-direction reference H1204, a Y-direction reference H1205, and a Z-direction reference H1206, which are positioning references.
  As shown in FIG. 1, the recording element substrates H1100 are arranged in a zigzag pattern on the recording element substrate support plate H1200 to enable wide recording with the same color. For example, four recording element substrates H1100a, H1100b, H1100c, and H1100d each having a nozzle group length of 1 inch + α are arranged in a staggered manner to enable recording of a width of 4 inches.
  In addition, the end of each ejection element group of each recording element substrate is provided with a region (L) overlapping with the end of the nozzle group of the recording element board adjacent to the staggered pattern in the recording direction.

  The plate member H1400 is formed of a SUS plate having a thickness of 0.5 to 1 mm, for example. The material of the plate member is not limited to SUS, and may be made of a material having ink resistance and good flatness. The plate member H1400 has a recording element substrate H1100 bonded and fixed to the recording element substrate support plate H1200 and an opening for taking in the recording element substrate, and is bonded and fixed to the recording element substrate support plate.

  Further, the external signal input terminal H1301 portion of the recording element unit H1001 is positioned and fixed on the back surface of the ink supply member H1501, for example.
(2) Description of Drive Circuit As shown in FIG. 1, in the recording head H1000 of the present application, four recording element substrates H1100 are accurately arranged on the recording element substrate support plate H1200, and further, four recording element substrates H1100 are electrically connected. Wiring is performed on the wiring board H1300. FIG. 8 is a circuit diagram showing signal wiring between the four recording element substrates. In the figure, H1100a to H1100d each correspond to four printing element substrates, and each printing element substrate is composed of driving circuits for odd and even two nozzle rows shown in FIGS. HEATO, E and IDATAO, E are taken out separately for each element evenly and oddly, and are indicated by signal names HEAT1-8 and IDATA1-8 for each recording element substrate. Other signals are wired in common between the recording element substrates. LTCLK, DCLK, HEAT 1 to 8, and IDATA 1 to 8 are connected to an external signal input terminal H1301, and VH, GNDH, VDD, and GND that are power supply systems are connected to a power supply terminal H1302.
  FIG. 4 is a diagram showing the configuration of the recording element substrate H1100. On the both sides of the ink supply port H1101, odd-numbered and even-numbered nozzle rows are shifted by half the nozzle pitch. These two drive circuits are formed on the recording element substrate by a semiconductor process, and signals HEATO, E and IDATAO, E are wired independently by each drive circuit, but other signals (DCLK, LTCLK) and The power supplies (VDD, GND, VH, HGND) are common wirings in the recording element substrate. In both the odd and even nozzle rows, 640 nozzles are arranged at a pitch of 600 dpi and are shifted by a half pitch as described above, so that a 1200 dpi, 1280 nozzle is configured as the recording element substrate. Since the drive circuit of each nozzle row is exactly the same, the outline of the drive circuit will be described with reference to FIG. Each of the nozzles 640 is provided with discharge heaters H1102-1 to 1279, and by driving each discharge heater, the ink in the nozzles is foamed and ink droplets are discharged. The 20 discharge heaters are divided into 32 drive blocks, each of which is driven in a time division manner. The drive block is selected by signals BE0-31, and the 20 discharge heaters belonging to the drive block determine whether or not to discharge by turning ON / OFF the transistors E1006-1 to E1006-1.
  The drive of the recording head H1000 will be described with reference to the drive timing chart of FIG. 9 and FIG. The PRINT signal is a pulse signal that gives the timing for starting ejection of one column, and the operation of the drive circuit starts at the rise timing of the pulse. When the drive circuit starts operation, LTCLK is generated first, and several hundreds ps after that, the transfer clock DCLK is output for the transfer data, that is, 25 clocks. Transfer data is output to each signal of IDATA1 to 8 in synchronization with DCLK and serially transferred to a 25-bit shift register E1001. The data stored in the shift register E1001 is stored in the 25-bit latch E1002 at the timing of LTCLK output at the beginning of the next drive block. Therefore, the actual driving is performed according to the first transfer data at the timing when the next block is transferred. The data content transferred here is a total of 25 bits, ie, the drive block number BENB0-4 is 5 bits and the drive data of the electrothermal transducer H1102 driven in that block is 20 bits. The drive blocks BENB0-4 are decoded into BE0-31 by the 5 → 3 decoder E1003 and connected to the base electrodes of the transistors E1005-1-312. Therefore, only one of the 32 transistors E1005-1 to 32 is always driven, and the drive power supply (VH) is supplied only to one end of the electrothermal conversion element belonging to the designated block. . On the other hand, the other ends of the electrothermal transducers H1102-1 to 1279 are connected in parallel by 32 for each segment, and are connected to the collector electrodes of 20 transistors E1006-1 to 20, respectively. The driving of these transistors is controlled by the outputs of AND gates E1004-1 to 20 connected to the base electrode. A 20-bit drive data signal is connected to one input of the AND gate, and pulse signals HEAT1 to 8 for giving timing for actually driving the electrothermal transducer are connected to the other input. Therefore, the transistors E1006-1 to 20 are controlled by AND of the two signals, and as a result, the segment specified by the 20-bit drive data is driven at the pulse timing of HEAT1 to 8. . As described above, when the PRINT signal is activated, the drive circuit starts to operate, the first block is driven first, sequentially becomes 1, 2,..., And finally the 31st block is completely driven. The ejection of all nozzles on the printing element substrate is controlled.
(3) Description of Inkjet Recording Device As shown in FIG. 5, the inkjet recording device M4000 of the present invention includes, for example, recording heads for six colors corresponding to photographic image quality recording. The recording head H1000Bk is a recording head for black ink, the recording head H1000C is for cyan ink, the recording head H1000M is for magenta ink, the recording head H1000Y is for yellow ink, the recording head H1000LC is for light cyan ink, and the recording head H1000LM is light. For magenta ink. These recording heads H1000 are fixedly supported by positioning means and electrical contacts M4002 of a carriage M4001 mounted on the recording apparatus main body M4000.
  These recording heads are controlled by the drive circuit described above to perform recording on a recording medium. 5 is a full-line type in which the recording head has nozzles corresponding to the width of the recording medium, the recording head is fixed, and recording is performed by scanning the recording medium in the direction of the arrow.
  On the other hand, the recording apparatus of FIG. 10 is a serial drive type recording apparatus in which the recording head performs recording while reciprocating in the main scanning direction (carriage movement direction).
  FIG. 11 is a diagram schematically showing a longitudinal section and a transverse section (a section obtained by cutting the longitudinal section along AA) of the recording head of the present invention. Four recording element substrates H1100 are mounted in a staggered arrangement on the recording element substrate support plate H1200.
  The recording element substrate support plate has a structure of two sheets, and a groove is independently formed on the side of the first support plate opposite to the recording element substrate arrangement surface. By attaching the second support plate, the flow path H1207 is formed. So that the cooling medium can flow. Further, the ink is supplied to the common liquid chamber H1501 of the head from the right side of the drawing and is collected and circulated from the left side, whereas the cooling pipe is supplied from the left side and is collected and circulated from the right side. . The cross section of the flow path H1207 is 2 mm wide and 1.5 mm deep in this embodiment. The flow rate of the coolant was about 20 ml / min to 100 ml / min. Of course, any flow rate that meets the conditions according to the printing conditions and head specifications may be used.
  The material of the support substrate is preferably a material having ink resistance and good thermal conductivity, such as alumina or carbon graphite.
  FIG. 12 schematically shows a partial cross section of the recording head when a cooling medium flow path H1207 is formed in the common liquid chamber H1501 as another embodiment of the present invention. Also in this case, since the cooling medium flows from the opposite side to the ink flow direction in the common liquid chamber, the temperature distribution in the head length direction can be reduced. In the case of this configuration, the distance from the recording element is longer than in FIG. 11 and the cooling efficiency is lowered, but there is a merit that the flow path diameter can be increased, which is effective in preventing temperature rise and reducing temperature distribution.
  Note that water, ink, air, nitrogen gas, and the like can be used as the cooling medium of the present invention, and particularly when temperature-controlled medium is circulated, temperature management and control are facilitated.
  FIG. 13 shows a comparison of the head temperature (increase) at the time of printing 50 sheets by the head of the present invention and the head without water cooling.
  Under the conditions of the present embodiment, when there was no water cooling, the temperature reached a high temperature after printing about 50 sheets, and the head temperature continued to rise and undischarge occurred. When the temperature at the time of 50 sheets was measured, the temperature on the downstream side on the left side was higher than the upstream side on which ink was supplied, and a temperature difference of 10 to tens of degrees was confirmed on the left and right of the head depending on the conditions. .
  In the method of the present invention, the head temperature is saturated at about 50 sheets, and the head temperature does not rise even if printing is continued thereafter, and the temperature difference in the length direction of the head can be suppressed to a problem-free level. It was.
  The temperature rise (ΔT) varies depending on the shape of the cooling groove, the flow rate of the cooling water, and the temperature, but it should be optimized depending on the specifications of the head used.
  14a) to 14d) show another embodiment of the present invention. Although not shown, the ink is supplied from the direction opposite to the direction of supplying the cooling liquid. a) is one in which three cooling medium flow paths are formed independently in parallel to the first embodiment. Although the supply system of the cooling medium is complicated, the temperature can be accurately controlled because the three can be controlled independently. b) is one in which three flow paths are provided and the cooling medium supply port is made common. In this example, the three supply systems cannot be controlled independently, but the cooling medium supply system can be simplified. c) is a system in which the cooling liquid flows in around the ink supply port to each recording element substrate and the recording element substrate is cooled. Since the cooling flow path is formed in the vicinity of the recording element substrate, the cooling efficiency is good and the ink flowing from the ink supply port can be cooled. d) is an embodiment in which ink is supplied from the center of the head, and cooling water is supplied from both ends of the head and collected near the center.
  FIG. 15 shows an example of the cooling system.
  The cooling medium is sent to the cooling medium inlet of the head by a pump, and returns to the thermostat again through the flow path in the head. The flow rate of the cooling medium is monitored by a flow meter, and the inlet temperature, the outlet temperature, and the head temperature are monitored, and the flow rate can be adjusted and the temperature of the thermostat can be controlled according to the printing conditions, the environmental temperature, and the like.
