This paper size applies to China National Standards (CNS) A4 specification (210X297 mm) (Please read the notes on the back before filling out this page) -8-200300709 Printed by the Consumers ’Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs A7 _ B7__ 五DESCRIPTION OF THE INVENTION (9) A load adjustment screw 28 having a spring 22 inside a load adjustment mechanism is provided on the upper part of the first seal retaining metal member 24, and the adjustment position is fixedly held by a fourth lock nut 29. Furthermore, One end of the spring 22 is on the upper part of the inner wall (ceiling) of the load adjustment screw 28, and the other end is supported on the edge portion (spring bearing) provided by the first pin 18. Furthermore, the load adjustment screw 28 and A gap adjustment screw 26 constituting the gap adjustment mechanism and a third lock nut 27 for fixing the adjustment position are provided between the first needle 18 and the first needle 18 and the seal ring holding of the adjustment mechanism section 5 are shown in FIG. 4. An enlarged view of a part of the metal member 24. As shown in the figure, the first sealing ring 16 used in this device has an elliptical cross-section, and is arranged such that its long-diameter side is in contact with the first needle 18. By doing so The elliptical shape of the first sealing ring 16 can reduce the movement of the first stitch 18 The effect of sliding resistance at the time. That is, the first needle 18 is moved within the range of elastic deformation of the first seal ring 16, and the sliding resistance is hardly generated, and the tightness between the adjustment mechanism 5 and the groove can be reliably maintained. The operation of the gap adjusting mechanism will be described below with reference to Fig. 5. The gap adjusting mechanism adjusts the distance between the spring seat seat provided on the first needle 18 and the first seal ring holding metal 24. The first needle 18 is movable This interval I. As shown in FIG. 5, in the state where the spring 22 is most reduced, the movement stroke of the first needle 18 is maximized. From this state, the spring is rotated by rotating the gap adjustment screw 26 in the direction in which the spring 22 extends, and the spring The seat will be pressed down, so that the moving distance of the first needle 18 will become smaller. That is, the distance between the spring seat provided at the first needle 18 and the first seal ring holding metal 24 will be smaller. Furthermore, When moving the sealing ring holding metal 24, loosen the third locking nut 27 in advance, and then tighten the third locking nut 27 after adjustment, so that the stroke of the first needle 18 will not change. Clearance (Please read the notes on the back before filling this page) This paper size applies National Standard (CNS) A4 specification (2 丨 0X297 mm) -9-200300709 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 _B7______ V. Description of the invention (9 The gap adjustment system first moves the gap adjustment screw 26 to Clearance state, and then • Rotate the clearance adjustment screw 26 or position the lock nut 27 in advance, and then adjust it by rotating the clearance adjustment screw 26. Next, the load for adjusting the operating pressure of the needle valve will be described using FIG. 6 Adjustment mechanism. The load adjustment mechanism is composed of a load adjustment screw 28 and a fourth lock nut 29. The outer circumference of the sealing ring holding metal 24 corresponds to the threads of the load adjustment screw 28 and the fourth lock nut 29. Instead, a thread is formed. After adjusting the amount of movement of the first needle 18 with the gap adjustment screw 26, loosen the fourth lock nut 29 and rotate the load adjustment screw 28 to adjust the number of rotations (rotation angle) from the reference position and adjust the spring 22 Force. By adjusting this spring force, the moving speed of the first needle 18 is controlled. That is, the opening and closing speed of the needle valve at the tip of the second needle 19 can be controlled. Next, the detailed structure of the nozzle part 11 is demonstrated using FIG. 8. FIG. Fig. 8 (a) is an enlarged sectional view of the nozzle portion 11. The lower end of the groove 10 is threaded, so that the needle seat 33 can be screwed. In addition, the bottom surface of the inner wall of the needle holder 33 and the front end portion of the groove 10 are in contact with each other through the washer 31 to prevent the discharged liquid from leaking to the outside. On the lower side of the needle holder 33, the nozzle holder 35 is screwed, and the nozzle 34 can be screwed to the front end of the nozzle holder 35. In addition, a needle piece 32 is provided on the upper portion of the nozzle 34, and can be attached to and detached from the nozzle 34. The front end of the second needle 19 is fitted into the opening of the needle holder 33 and the needle holder 32 to function as a needle valve. FIG. 8B shows another shape of the nozzle 34. As in the present embodiment, the outer shape of the nozzle portion is made the same. By cutting the discharge side into a V shape and shortening the fluid flow path of the nozzle portion 11, the discharge resistance of the fluid can be reduced and the discharge can be performed stably. In addition, because the discharge section is located at a lower stage, it is not easy to be disturbed by external interference (please read the precautions on the back before filling this page).

Impact of invention (i (down flow)). Even if a nozzle or a tool is accidentally touched when the nozzle falls or comes off, the impact on the ejection tip portion can be reduced. Next, the operation of the feeder configured as described above will be described with reference to FIG. 1. Furthermore, the use will be explained here. In the case where the liquid crystal agent or sealant is coated on the substrate by this feeder. First, the load adjustment mechanism and the gap adjustment mechanism are operated, and the needle operation speed and the needle valve opening degree are set. The lid 14 of the tank 10 is opened to add liquid. After these adjustments are completed, a substrate (not shown) is set at a position (horizontal position) at which the dispenser will discharge the desired liquid. Here, the motor 12 is driven to make the nozzle The space between the tip and the substrate is at a predetermined position, and the height position of the groove 10 is moved along the elevating guide 13. Then, a pressurized gas from a pressure source (not shown) is passed through the pressurizing joint 6 Into the tank. As a result, the liquid in the tank is increased by a predetermined pressure. Then, the electromagnetic coil 1 is operated according to an external electrical signal, and the first and second needles 18 and 19 are driven to move the second needle. The front end portion (needle valve) of 19 opens and closes the flow path of the needle seat 33. As a result, a predetermined amount of pressurized liquid is discharged from the nozzle 34 onto the substrate. As described above, when the feeder according to this embodiment is used, The opening degree and opening / closing speed of the needle valve can be easily set, and even if the needle is replaced, it has the effect of only having to replace the second needle. Moreover, it is possible to control the discharge amount as desired by the user. It can be used as a component for easy cleaning of syringes and valve stems, and easy replacement of nozzles and valves. It can also adjust the discharge amount of liquid with high accuracy.
