Abstract

PURPOSE:To make it possible to take up a predetermined amount of a flowable material, by cutting the fluid material by a cutter when a predetermined amount of the fluid material is emitted. CONSTITUTION:A resin is sucked in a syringe 1 while the syringe 1 is fixed to a holder 8. Next, a linear motor 9 is operated and a spindle 10 is moved to the position of a piston 7 to be connected to said piston 7. Further, the linear motor 9 is operated in such a state that a pen cylinder 11 is retracted to press the piston 7. The resin 4 pressed by the piston 7 is emitted from an emitting port 2 in a rod shape. When the resin 4 emitted from the emitting port 2 reaches a preset necessary emitting amount, a photosensor 13 is operated to stop the operation of the linear motor 9 and the pen cylinder 11 is operated to cut the rod shaped resin 4 by a cutter 12. By this method, the quantitative ejection of the resin is enabled.

Description

[Detailed description of the invention] [Industrial application field] This invention is applicable to potting (filling), sealing (sealing)
The present invention relates to a fixed-quantity dispensing device for fluid used in operations such as the above.

[Conventional technology]

A conventional quantitative dispensing device for this type of fluid was constructed as shown in FIG.

That is, in FIG. 3, 1 is a syringe, 2 is a discharge port, 3 is a cap, 4 is a liquid resin stored in the syringe 1, 5 is an electromagnetic valve, and 6 is an air source. In this conventional device, when a potting resin 4 is placed in the syringe 1 and the electromagnetic valve 5 is opened, the air pressure increases to 411114.
The resin 4 is applied to the surface of the resin 4 and is discharged from the discharge port 2. When the electromagnetic valve 5 is closed, the discharge of the resin 4 is stopped.

Here, if the solenoid valve 5 is configured to be controlled by a timer (not shown) and the solenoid valve 5 is controlled to open and close at predetermined time intervals, the discharge port 2
The resin 4 is then discharged at regular intervals. Therefore, if the air pressure is kept constant, the required amount can be discharged by changing the discharge time.

However, in this conventional product, the resin 4 is liquid and has a viscosity of 1
It is suitable for things under 10,000 cps, but for example 200,000 C
Fillers of PS or higher, such as silica, tankal, etc.
If the resin has a high viscosity of 50 parts by weight or more, there will be a time lag between when the pressurizing air presses against the resin surface and when the resin surface moves. Therefore, it cannot be used in an automatic mass production system that is linked to the movement of the discharged object. In addition, the 41 resin discharged from the discharge port 2 has a very high viscosity and is mixed with filler, so the resin does not stretch and is difficult to cut in a continuous state, making it impossible to discharge a fixed amount. there were.

This invention was made to solve the drawbacks of such conventional products, and it
The present invention is intended to provide a fluid metering discharge device suitable for resins of 00,000 CPS.

[Means for Solving the Problems] A fixed-quantity dispensing device for a fluid according to the present invention includes a device for detecting that a predetermined amount of fluid discharged from a discharge port has reached a predetermined amount of fluid in a container, and The cutting device is configured to cut a predetermined amount of the fluid discharged from the container by the cutting device.

[Effect]

In this invention, it is possible to accurately take out a predetermined amount of fluid.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. That is, in FIGS. 1 and 2, 7 is a piston that fits into the syringe 1 and discharges the resin 4 in the syringe 1, 8 is a holder for fixing the syringe 1, and 9 is a piston that is connected to the syringe 1 via a spindle 10. 11 is a pen cylinder that drives a cutter 12 having a wire 13 that cuts the resin 4 discharged from the discharge port 2 of the syringe 1; A photosensor is arranged near and parallel to the central axis of the discharge port 2 to detect the length of the discharged resin 4 and control the operation of the linear motor 9. The wire 13 used in the cutter 12 has a diameter of 01 to 0.
．． A stainless steel plate with a thickness of about 0.1 mm may also be used, although a thickness of about 2 mm is suitable.

In the case of the structure shown in B, resin is inhaled into the syringe 1 and fixed to the holder 8. Next, the linear motor 9 is operated to move the spindle 10 to the position of the piston 7 and connect it. Further, the pen cylinder 11 is moved backward, and the linear motor 9 is operated to push the piston 7. The resin 4 pressed by the piston 7 is discharged from the discharge port 2 in the form of a rod. When the amount of wood 114 discharged from the discharge port 2 reaches a required discharge amount, which is preset in terms of length, the photo sensor 13 is activated.

By the operation of this photosensor 13, the linear motor 9
The operation of the pen cylinder 1 is stopped and the rod-shaped resin 4 is cut by the cutter 12.

By combining mechanisms that operate in this way,
There is no time lag in the operation of each device, and it is possible to discharge a fixed amount of 1m4 fat.

〔Effect of the invention〕

As described above, the fluid dispensing device according to the present invention is configured to detect and cut a predetermined amount of fluid discharged, and can accurately take out a predetermined amount of fluid.
