FIG. 3 is an enlarged sectional view of a part A in FIG. 1 showing a state in which the needle valve of the adhesive application device is moved downward, and FIG. 4 is a schematic view showing an outline of the adhesive application device.

  1 to 3, the adhesive application device in one embodiment of the present invention injects one solution 12 from one injection unit 11 and injects the other solution 12 from the other injection unit 11. The solution 12 is brought into contact and reacted to be used as a mixed adhesive coating apparatus.

  The one injection part 11 and the other injection part 11 have a storage tank 13 for storing the solution 12 and a viscosity and the other of the one solution 12 stored in the storage tank by heating or cooling the stored solution 12. A temperature control unit 14 for controlling the temperature of each solution 12 and an injection nozzle 15 for injecting the stored solution 12 are connected to the lower part of the storage tank 13 so that the viscosities of the solutions 12 are substantially the same. Provided.

  The solution 12 is replenished by pressurizing air from the solution tank 16 to the storage tank 13 by air pressure, and the solution 12 is also filled from the storage tank 13 into the injection nozzle 15 by the inflow pressure at the time of the pressure inflow.

  An impact is applied to the injection section 11 from the upper side to the lower side of the injection nozzle 15, and the solution 12 (corresponding to B in FIG. 2) in the storage tank 13 facing the injection nozzle 15 is injected into the injection nozzle 15. A needle valve 17 is provided for filling.

  The needle valve 17 is arranged vertically, the tip surface 19 thereof is arranged horizontally, and the tip surface 19 is filled with the solution 12 in the injection nozzle 15 by the inflow pressure when the solution 12 is replenished. There is provided a shut-off valve 18 for temporarily shutting off.

  The one injection unit 11 and the other injection unit 11 are configured so that the solution from the injection nozzle 15 is affected by the impact that the needle valve 17 applies to the injection nozzle 15 and the filling pressure that the needle valve 17 fills the injection nozzle 15 with the solution 12. 12 is injected. The injection unit 11 is moved horizontally to inject the other solution 12 from the other injection unit 11 toward the one solution 12 injected from the one injection unit 11. At this time, the passage sensor 20 is attached in the vicinity of the tip of the injection unit 11 so that the solution 12 can detect the injection state.

  In such an adhesive application device, as shown in FIG. 4, an injection head 23 including an injection unit 11 and a solution tank 16 is movable to the left and right on a component 22 which is an object placed on a base 21 of the device. By doing so, injection can be performed.

  With the above configuration, the impact is given to the injection unit 11 and the solution 12 is injected from the injection nozzle 15 by this impact. Therefore, the adhesion area of the solution 12 that is injected and adhered to the object can be reduced, and even if the object is small Adhesive reliability can be improved without the mixed adhesive sticking out of the object.

It can be done smoothly. In particular, when the needle valve 17 is provided with a shut-off valve 18 for blocking the injection nozzle 15 from being filled with the solution 12 by the inflow pressure when the solution 12 is replenished, and the needle valve 17 gives an impact to the injection nozzle 15. Since the solution 12 is not filled in the injection nozzle 15 at the time of shut-off, and the needle valve 17 is moved upward to release the shut-off, the solution 12 is put into the injection nozzle 15. Can be carried out more smoothly.
