Detailed ways

Referring to FIG. 1 and FIG. 2 , a preferred embodiment of the present invention provides an automatic drug adding device 100 . The automatic chemical adding device 100 is coupled to at least one magnetic grinder 200 for adding a chemical to the surface of the workpiece (not shown) processed by each magnetic grinder 200, thereby removing the surface of the workpiece and oil stains and burrs. The medicament can be It is a brightener.

The automatic chemical adding device 100 includes a liquid storage tank 10 and an inflatable member 20.

The liquid storage tank 10 is for accommodating the medicament. The liquid storage tank 10 includes a tank body 12 and a lid body 11 that is covered by the tank body 12. The can body 12 is for receiving the medicament. An inflation duct 110 is connected to the cover 11. A liquid filling pipe 111 is also connected to the cover body 11. In other embodiments, the inflation duct 110 and the liquid filling duct 111 may also be disposed at other locations of the liquid storage tank 10.

In the present embodiment, the liquid storage tank 10 is substantially cylindrical and is formed by bending and welding a stainless steel plate having a thickness of 4 mm. The liquid storage tank 10 has a withstand voltage of 1.5 MPa.

The inflatable member 20 is coupled to the inflation duct 110. The inflatable member 20 is configured to charge compressed air into the liquid storage tank 10 through the inflation duct 110, so that the air pressure in the liquid storage tank 10 is increased, so that the medicine flows out of the liquid storage tank 10 and Entering the liquid filling pipe 111. In the present embodiment, the inflatable member 20 is an air compressor.

The end of the liquid filling pipe 111 away from the liquid storage tank 10 is located above a support base 300 of the automatic chemical adding device 100. The supporting base 300 is used for supporting a material box 1 Said in the box 1. That is, when the tank 1 is transferred to the support base 300, the medicine in the liquid filling pipe 111 can be directly added to the surface of the workpiece in the tank 1. In the embodiment, the end of the liquid filling pipe 111 can be connected to a spray head 112 for uniformly spraying the medicament on the surface of the workpiece.

The magnetic grinder 200 is connected to the support base 300 through a conveyor belt 400. After the different workpieces are processed by the magnetic grinder 200, they can be placed in the magazine 1 and transported to the support base 300 via the conveyor belt 400.

In the present embodiment, the automatic chemical adding device 100 further includes a solenoid valve 30, an inductor 40, and a timer 50.

The solenoid valve 30 is connected to the liquid filling pipe 111 for opening or closing the liquid filling pipe 111 to allow or prevent the medicament from flowing out from the end of the liquid filling pipe 111.

The inductor 40 is disposed on the support base 300 and electrically connected to the electromagnetic valve 30. The inductor 40 is used to sense whether the bin 1 has been placed on the support base 300. If so, the sensor 40 sends an opening signal to the solenoid valve 30 for controlling the opening of the solenoid valve 30 to allow the medicament to flow out of the end of the liquid filling conduit 111. At this time, the medicament may be directly added to the surface of the workpiece in the tank 1. In the embodiment, the inductor 40 is a weight sensor, and the sensor 40 can sense the weight of the support base 300 when the bin 1 has been placed on the support base 300. Varying to generate the turn-on signal.

In the embodiment, the liquid filling pipe 111 is further provided with a flow sensor 113 electrically connected to the electromagnetic valve 30. The flow sensor 113 is configured to sense a flow value of the medicament in the liquid filling pipe 111, and send a flow to the electromagnetic valve 30 when the flow value is not within a preset flow range An adjustment signal is used to control the solenoid valve 30 to adjust its opening size to correspondingly increase or decrease the flow rate value of the medicament.

The timer 50 is electrically connected to the solenoid valve 30. The timer 50 is configured to time the solenoid valve 30 when it is started to open, and when the opening time of the solenoid valve 30 exceeds a preset time value, send a closing signal to the solenoid valve 30, the closing A signal is used to control the solenoid valve 30 to close, thereby preventing the medicament from flowing out of the end of the liquid filling conduit 111. Therefore, the timer 50 can control the addition time of the medicament to achieve the purpose of timing and quantitatively adding the medicament. The timer 50 can be a time relay. The preset time value may be set according to production requirements, wherein the addition time of the medicine required for the workpiece processed by the different magnetic grinder 200 may be different, and the preset time value may also be different. Therefore, by controlling the opening time of the solenoid valve 30 by the timer 50, it is possible to quantitatively add a chemical to the workpiece processed by the different magnetic grinding machine 200.

In summary, after the workpiece is sensed, the automatic chemical adding device 100 can automatically add a medicament to the surface of the workpiece, thereby replacing the existing manual working mode, reducing the waste of action and improving the production efficiency. Furthermore, by the timer 50 The opening time of the electromagnetic valve 30 is controlled, so that the addition time of the medicine can be controlled, and the purpose of quantitatively adding the medicine can be achieved, and the adverse effect on the appearance and quality of the workpiece can be avoided when the proportion of the addition is uneven.
