The j-outlet 70 used in the coating device is proposed to have a plunger-type discharge unit that moves in and out at two speeds and causes the liquid material to fly from the spout outlet by a Plunger that is in close contact with the movement of the advancement and retreat in the metering tube. When the spouting unit is used for a long period of time, the internal sliding parts and the like are worn out, and a gap occurs between the parts to leak liquid material therefrom. Further, even if it is not used for a long period of time, the discharge unit is disassembled for maintenance or the like. :::: The technical difference between the two operators is that the liquid material cannot leak smoothly from the other, and the clothing is broken, and the liquid material leaks from the space. When the shape of the ^ can be properly tightened, the self-locking portion will also have a liquid material leaking out of the discharge device. The discharge unit is coated with the liquid material. 97105003 5 200843864 However, when the Z-disposal/fruit sap liquid Z is applied to the object to be coated, it becomes a defective product: wide or cost. In the production step t, if there is no step for immediate detection, During the period of growth, the production of defective products continues, and the time and cost of the product are increased. In the worst case, the quality may be linked. In Patent Document 2, the coating device can detect the leak. According to the liquid device, since the main body of the coating device is disposed so as to be movable (see: a liquid-feeding pipe for supplying a liquid material), the liquid-feeding pipe can be operated in such a manner as to discharge the unit. And it is housed in the cable device. ± ", ^ ^ The operation of the discharge unit is such that if the liquid pipe is degraded and the liquid leakage occurs, the liquid leakage is detected, and the cable support guide device for accommodating the liquid communication pipe is accommodated. The bottom of the accommodating portion is provided with a liquid leakage sensor. Patent Document 1: Japanese Patent Laid-Open Publication No. Hei. No. 2006-106150 (Patent Document No. JP-A-2004-243186) Problem) The detection device of Patent Document 2 is detectable When the material is supplied to the discharge unit, the liquid material is leaked from the liquid pipe, and the purpose is not direct; if the detection device of the liquid material leaked from the discharge unit is leaked from the discharge unit, it is not The means to prevent the liquid from dripping onto the coated object is not the means for detecting the liquid leakage in the discharge unit. In the case of Ya, there is no direct solution to the leakage of the liquid material from the discharge unit. 97105003 6 200843864

Further, γ can be detected with high accuracy even if a small amount of liquid leakage, and e can be detected from the discharge unit regardless of the moving position of the discharge unit. [Embodiment] A liquid leakage detecting device for carrying out the best mode of the present invention can be mounted on a general liquid material applying device. Hereinafter, the discharge unit 2 having the discharge port capable of discharging the liquid material; and the drive unit 5 for allowing the discharge port to move parallel to the application target surface of the workpiece; and the liquid material application device 丨An example. The liquid leakage detecting mechanism according to the preferred embodiment of the present invention is characterized in that: the outer edge rising portion 9; and the opening portion 1 provided in the discharge port facing the discharge unit; and the opening portion surrounding the opening portion The liquid receiving tray 3 of the starting portion u; and the liquid leakage detecting device 4 disposed on the liquid receiving tray 3; The liquid receiving tray 3 of the liquid material leaked from the ai soil discharging unit 2 is in the form of a disk, and the body material receiving surface 8 is provided to vertically surround the outer edge of the periphery. Hunting is thus an outer edge rising portion 9 which prevents the liquid material from flowing out to the liquid bearing 97105003 9 200843864. Further, similarly to the opening rising portion n provided in the opening portion 1, the liquid material can be prevented from flowing out. When the drip pan 3 is formed as a slope facing the deepest portion (for example, Fig. 7), the outer rim rising portion 9 is not necessarily required. However, in order to install the assembly of the drip pan 3, the screw 2: 2, 1 and 5 parts, or in order to reinforce the bending or flexing of the liquid receiving tray 3, the design of the temple is self-designed. It is preferable when the outer edge rising portion 9 is provided. ^ From the viewpoint of preventing leakage of the liquid, it is preferable that the drip pan 3 is disposed immediately below the spit early 70 2 . Although the drip pan 3 can be installed in various aspects, for example, it can be directly disposed in the discharge unit 2, or the connection member 7 of the ':: soap element 2 and the driving unit 5 can be disposed. Connecting member 7: The liquid receiving container 3 is detachably constructed by means of an assembly. This assembling tool includes a part of the fixing liquid receiving pan 3 and the connecting member 7 with a screw member or the like (refer to FIG. 2), and a sample holder (see FIG. 9) that holds the lower surface of the drip pan 3 (see FIG. 9). A wide range of assembly tools. What is important at this time is: , : = The discharge unit 2 and the drip pan 3 can be moved integrally. When it is integrated, it can prevent the liquid from dripping onto the object to be coated regardless of the moving position of the discharge unit 2. Preferably, the drip pan 3 is mounted in position with a liquid material receiving surface 8 facing the horizontal plane. When formed in a slanted shape, the liquid material gathers toward the lowest portion 17 and flows down. The deepest portion 17 may be formed by enclosing the liquid material, forming a slope, and having the deepest portion 17 located below the slope to shape the shape of the eight liquid pan 3 itself. The liquid material receiving surface 8 of the liquid receiving tray 3 can be made to be inclined to the horizontal plane, or besides the inclined surface of the liquid material receiving surface 8 itself, so that the liquid material receiving surface 8 can be made waterproof (water_repeUant), thus The liquid material can be easily discharged. In order to have water repellency, it is possible to produce a liquid-repellent disk 3 itself by a material having water repellency, and a material having water repellency covering the liquid material receiving surface 8 is realized. The material having water repellency is an i-type resin or a Shih-ray resin. However, since the types of these materials are designed to be considered for the financial properties of the liquid material to be coated, the above-mentioned types are not Limited. The printing detecting device 4 is a detecting means such as an optical sensor, and is disposed on the liquid receiving tray 3 so that the discharge unit 2 and the liquid receiving tray 3 can be moved together. And it is disposed at the lowest point where the liquid material in the liquid material receiving surface 8 of the liquid receiving tray 3 flows down. When the receiving surface 8 itself is formed, and the concave portion is formed in the deepest portion 17, the detecting device 4 is attached to the concave portion. In this case, if it is easily installed and removed, the liquid material adhering to the drip pan 3 or the detecting device 4 can be wiped off in a timely manner, which is preferable. Further, since it is provided at a place where the liquid material is collected under the flow of the liquid material 17, it can be detected even when the amount of liquid leakage is small. When it is detected that the liquid material leaks from the discharge unit 2, the detection signal sent from the detecting device 4 is received, and an alarm notification is issued to stop the discharge operation of the discharge unit 2. This configuration is also possible. "The discharge unit 2 is exemplified by a plunger type discharge unit, but the type of the discharge unit is not limited thereto. For example, if the liquid material in the syringe of the front port is used, only The time of the Greek = 97105003 200843864 is added to the regulated air, so the air ejection unit can also be 0. The detecting device 4 is not limited to the optical sensor, as long as it is a sensing person who can detect the liquid material. Alternatively, other detection devices may be used. For example, a dynamometer (1 〇ad ce 11) may be used to detect the weight of the liquid material flowing down. Also, if a camera is used to detect the captured flow The present invention is described in detail below with reference to the embodiments, but the present invention is not limited to any of the embodiments. [Embodiment 1] Fig. 1 is a liquid leakage detecting mechanism having the liquid leakage detecting mechanism of the first embodiment. A schematic oblique view of the coating apparatus. The coating apparatus disclosed in Fig. 1 has three discharge soaps 2 attached to the driving unit 5, and each of which is provided with a liquid holding tray 3 and a detecting device 4. Unit 2 is provided with a liquid receiving tray 3, and the detecting device 4, any of the discharge units 2 can detect whether or not the liquid material leaks. The size of the discharge unit 2 is based on the size of the workpiece 6 to be coated, the coating method, and the like. The matter is not limited to three, and may be two or less or four or more in the opposite. Of course, if a plurality of ejection units 2 are provided, a liquid leakage detecting mechanism is provided on all of the ejection units 2. Preferably, the coating device 1 is provided with a driving portion 5 for moving the spout 2 having the discharge port in a plane parallel to the application target surface of the workpiece 6. The liquid receiving tray 3 is provided with a connection/ That is, the head (4) 7 1 (4) spout out the early 7^ 2 and the connecting portion 7 of the driving portion 5, since the detecting device 4 is provided on the liquid receiving tray 3, the ejection unit 97105003 12 200843864 unit 2 and the liquid receiving tray qb are placed. In the spit unit; ==:4 can: Zhao move. The workpiece 6 is loaded again, by the drive unit 5 on the flat surface (workbench) of the workpiece 6 ^. The surface moves, while the spit out / early 70 2 along the hope Trajectory of a material. The hunting outlet spits out the liquid material and applies the liquid to the workpiece 6 to move t::: I speed: unit 2 makes The plunger-type discharge device that is in close contact with the material in the metering tube moves out and drops the liquid material from the spit outlet to the Si material. The over-discharge unit 2, the liquid-bearing tray 3, and the detection device 4 are as follows: 3 - strabismus Fig. 3 shows an enlarged perspective view of the liquid-retaining tray 3. The production of the large-phase I-phase Γ 'the shape of the liquid-retaining tray 3 and the bottom surface of the discharge unit 2 are 8 rectangular-shaped rectangular plates on the outer edge portion, and The liquid material receiving portion (7) has a rising portion 9 around the outer peripheral edge. The outer edge rising portion 9 prevents the liquid material from being provided to the portion directly below the nozzle which flows out of the liquid receiving tray 3, and the opening portion 1 is provided. The ι〇: part is also provided with an opening rising portion η, and the opening portion 10 for discharging the liquid material prevents the liquid material from flowing out of the liquid receiving tray 3. As shown in Figs. 2 and 4, the drip pan 3 is fixed to the connecting member 7 by the screw member 21 and disposed directly below the discharge unit 2. At this time, the drip pan 3 is disposed to vacate a predetermined gap with the discharge unit 2. This gap is also the one that allows the liquid material to flow easily. However, depending on the flow state of the liquid material, a portion of the liquid material receiving surface 8 of the drip pan 3 is brought into contact with the bottom surface of the discharge unit 2 in such a manner that the liquid receiving tray 3' is provided. 97105003 13 200843864 j The drip tray 3 and the discharge unit 2 are independent and are mounted on the movable connecting member 7 of the drive =. Therefore, only the discharge unit 2 can be attached and detached under the circumstance of setting the drip pan 3. In the state in which the bearing member (4) 3 is disposed in the connecting member 7, the liquid material receiving surface 8 has an inclined shape to the horizontal surface. The method of tilting can be considered in various ways. For example, the liquid material receiving surface 8 can be held in a planar shape as shown in Figs. 4 and 5, and the liquid receiving tray 3 itself can be tilted and fixed. Specifically, first, the Γ = side is tilted downward (Fig. 4), and in this state, the left side is set to be lower (Fig. 5). Thus, the left front becomes a lower position in the drip pan 3, and the leaked liquid material gathers in the left front to flow down. Further, the liquid material receiving surface 8 may be formed to have an inclined shape. The inspection device 4 is placed at the deepest portion 17 in front of the lowest position in the tilting-mounted drip pan 3. The detecting device 4 is provided to be easily mounted and detached.
