The support plate provided on the support shell (4) includes a bottle 532 of the (4), and a connection 3-4 of the connection; Tube 533 with the bottle 532 〇 201102176 523 Nozzle unit 540 is connected to the outflow channel in the barrel assembly 52. When configured as described above, the coating head device of the liquid crystal coater operates as follows. The cartridge assembly 52 for the insertion of the piston 510 utilizes the bottom of the coupling unit _f housing 430. At this time, the female connecting member of the piston commits the male connecting member 651 that connects the second shaft 650. The actuator 540 operates to move the second shaft 65A upward, thereby moving the piston 510 upward. Thus, the female connecting member 512 of the piston 51 is inserted into the funnel-shaped hole 631 of the first shaft_, and is firmly fixed in position. The first rotary motor 620 operates to rotate the first shaft 63 (), in close contact with the first shaft 63 活塞 the connected piston 51 〇 , and the second shaft ( 10 ). First, the rotary motor 620 rotates the piston 510 such that the groove 513 in the piston 510 faces the inflow passage 522 in the cartridge assembly 520. ★ The linear drive unit 7〇〇 moves the rotary drive unit 6〇〇 up a predetermined distance, thereby moving the piston 510 connecting the second shaft 650 upward. The upward movement of the piston 51 turns a pressure difference between the piston hole 521 and the inside of the liquid crystal supply unit 530. Thus, the liquid crystal flows from the liquid crystal supply unit 53 into the piston hole 521. The first rotary motor 620 rotates the piston 510 such that the groove 513 in the piston 510 faces the outflow passage 523 in the barrel assembly 52. Each time the linear drive unit 7 〇〇 moves the rotary drive unit 6 and the piston 510 downward by a predetermined distance 'through the outflow passage 523 in the cylinder assembly 52 自 from the spray 201102176, the nozzle unit drips to the substrate. The rotary drive unit_and the piston 51〇 continue to move downward until a pre-recorded amount of liquid crystal droplets are dropped toward the substrate/in the coating head device of the liquid crystal coater as described above, and the rotary piston 510 rotates the fresh element 6GG with/on/ The linear drive unit 70 700 of the lower jaw_axis unit is held at a predetermined distance from each other, but is connected to each other with the moving member. This causes the rotary drive unit 600 to generate a torque to the linear drive unit 〇〇. As a result, the second guiding unit 450 and the moving member 71 are in a centrifugal load. Therefore, the rotary drive unit 6 is moved up/down in a manner that the heavy load linear scale scale cannot be read smoothly. Further, the linear drive unit 700 is positioned between the rotary drive unit 6A and the coating head unit frame 300. Thus, the coating head device frame 3 is extended horizontally forward, cloth, and device. This configuration causes the coating county to generate a torque that greatly affects the first guiding unit 310. Therefore, the first guiding unit 31 is in a heavy centrifugal load. This prevents the coating head unit from moving in a smooth manner and causes the drive unit D2 to be in a bulky load.

The rotary screw of the ball screw 853 moves the connecting member 854 and the rotary drive unit 84 connected thereto to a predetermined distance ′, thereby moving the piston 830 of the second shaft 845. The upward movement of the piston 830 creates a pressure difference between the piston bore 821 and the inside of the liquid crystal supply unit 880. Thus, the liquid crystal flows from the liquid crystal supply unit 88 into the piston hole 821. The first rotary motor 842 rotates the piston 83〇 such that the groove 833 in the piston 83〇 faces the outflow passage 823 in the barrel assembly 820.

This configuration allows the coating head unit to be fully assembled. That is, the coating head device has a small range of horizontal embedding from the coated thief frame. The amount of torque to be applied to the first guiding unit 310 is thus lowered. As a result, the second drive unit 〇 2 is in a less heavy load when the second drive unit D2 moves the coating head unit. A second embodiment of a coating head device is now known.

The bead screw passes through the screw hole of the sliding member 922 t but is located between both ends of the ball screw 853. The ball screw 8 is connected to the lower member 814. Also know that you can turn red 922. The up/down movement of the second rotary motor 852 moves the slide member up/down to rotate the drive unit 840.

The motor connecting member 851 and the second rotating motor are the same as those of the first embodiment. 852, and Ball Screw 853 The operation of the coating head device of the third embodiment will now be described. The difference between the operation of the embodiment and the first embodiment is that the third driving unit moves the sliding member 922 up/down by the linear driving unit 85, and the rotating driving unit 84 provided on the sliding member 922 moves up/down. And the first ^

The embodiment is a rotational movement connecting member 854 of the ball screw 853, whereby the rotary drive unit 840 is moved downward. The ball screw 853 of the linear drive unit (4) is not at the same centerline as the first shaft 845 of the rotary drive unit_ but the ball screw 853 is adjacent to the second shaft. This allows the rotary drive unit 84() to produce a relatively small amount of torque toward the linear drive unit 85'. The outer portion can be made to slim down the coating head device by positioning the ball screw 853 of the linear driving unit 85A and the second shaft 845 of the rotary driving unit 840 adjacent to each other. That is, the coating head device protrudes from the coating head device frame 3 to a level that is less than the 201102176. η is touched at 3 touches, and this (4) can be implemented in many forms. 'It should also be understood that unless otherwise specified, there is no limit to the details, but 庳/贝J does not have any explanation of ^, therefore All falling-off applications apply for the equivalent of the scope of the benefits.
