The first embodiment is as follows: as shown in fig. 1 to 3, which are only one embodiment of the present invention, an output detection device for an optical cement coating includes a coating material tank 1 and a three-way valve 2, three connection ports of the three-way valve 2 are respectively connected with a discharge pipe 3, a return pipe 4 and a discharge pipe 5, one end of the discharge pipe 3 away from the three-way valve 2 is communicated with the coating material tank 1 through a discharge pump 31, one end of the return pipe 4 away from the three-way valve 2 is communicated with the coating material tank 1 through a return cylinder 41, a first valve 42 is disposed between the return pipe 4 and the three-way valve 2, a second valve 43 is disposed between the return cylinder 41 and the coating material tank 1, a return detection portion 44 is disposed on the return pipe 4, a return display screen 445 is disposed on the return detection portion 44, a third valve 51 is disposed between the discharge pipe 5 and the three-way valve 2, the output pipe 5 is provided with an output detection part 52, the output detection part 52 is provided with an output display screen 525, and the material return barrel 41 is provided with a material return amount scale 411.
Here, the optical cement paint is loaded in the paint tank 1, the paint tank 1 is provided therein with a conventional stirring device and a charging port, the charging port can be added with optical cement raw material (solute) and optical cement solvent (solvent), the optical cement paint in the paint tank 1 flows into the three-way valve 2 through the discharging pump 31 and the discharging pipe 3, and when the first valve 42 is opened, the optical cement paint in the three-way valve 2 can flow into the returning pipe 4 and the returning cylinder 41; when the second valve 43 is opened, the optical cement paint in the feed back cylinder 41 can be returned to the paint tank 1; when the third valve 51 is opened, the optical cement paint in the three-way valve 2 can flow to the output pipe 5 to be output and coated on the surface of the product for use.
It should be noted that the discharge tube 3, the return tube 4 and the output tube 5 are all non-transparent pieces.
Before the paint is used, the properties of the paint should be detected, wherein the detected properties include viscosity and stability, the stability is whether the paint concentration is uniform or not and the discharge rate is constant, at this time, the first valve 42 should be opened, the third valve 51 should be closed, so that the optical cement paint only flows into the material return pipe 4, and the second valve 43 is closed, so that the optical cement paint is prevented from returning into the paint tank 1 to influence the calculation. At this time, the optical cement paint flows into the material return cylinder 41 through the discharge pump 31, the discharge pipe 3, the three-way valve 2, and the material return pipe 4, and the nature of the paint is detected by the material return detection part 44 on the material return pipe 4 and the material return amount scale 411 of the material return cylinder 41.
Here, the feed back detection part 44 includes a feed back elastic plate 441 and a feed back detection plate 444, one end of the feed back elastic plate 441, which is far away from the three-way valve 2, is provided with a feed back magnetic member 442, one end of the feed back elastic plate 441, which is far away from the feed back magnetic member 442, is fixed to the side wall of the feed back pipe 4, one end of the feed back elastic plate 441, which is close to the feed back magnetic member 442, is connected to the side wall of the feed back pipe 4 through a feed back elastic column 443, the feed back detection plate 444 is a PCB plate disposed in the magnetic field range of the feed back magnetic member 442, and the feed back display screen 445 is electrically connected to the feed back detection plate 444.
When the optical cement coating passes through the material return pipe 4, the obliquely arranged material return elastic plate 441 is pushed to deform, so that one end, close to the material return magnetic piece 442, of the material return elastic plate 441 bends towards the wall direction of the material return pipe 4, and when the PCB board material return detection plate 444 in the magnetic field range of the material return magnetic piece 442 detects the displacement of the material return magnetic piece 442, an electric signal is generated and sent to the material return display screen 445 to be displayed.
The display numerical value of the feed back display screen 445 is related to the viscosity value and the flow rate of the optical cement coating, the larger the flow rate is, the larger the extrusion force on the feed back elastic plate 441 is, the larger the displacement of the feed back magnetic element 442 is, and the larger the display numerical value of the feed back display screen 445 is; similarly, the higher the viscosity value of the optical cement coating, the higher the extrusion force on the returned material elastic plate 441 is, the larger the displacement amount of the returned material magnetic element 442 is, and the larger the display numerical value of the returned material display screen 445 is.
The feed back cylinder 41 is provided with a first plate 411, a second plate 412 and a connecting rod 413 for connecting the first plate 411 and the second plate 412, the first plate 411 is disposed in the feed back cylinder 41, the second plate 412 is disposed outside one end of the feed back cylinder 41 far away from the second valve 43, and the feed back amount scale 414 is disposed on a side wall of the connecting rod 413.
When the optical cement coating flows into the feed back cylinder 41, the volume of the optical cement coating becomes large, the first plate 411 is extruded to move upwards, the second plate 412 and the connecting rod 413 are driven to move upwards, the reading of the feed back amount scale 414 on the connecting rod 413 and the upper surface of the feed back cylinder 41 which are flush is the volume value of the optical cement coating which currently flows into the feed back cylinder 41, and when the reading value of the feed back amount scale 414 becomes large and stable, the flow rate of the optical cement coating is constant.
At this time, once the display value of the feed back display 445 is unchanged for a period of time, it indicates that the viscosity value of the optical cement coating flowing through the feed back pipe 4 is constant during the period of time.
It should be noted that, since the optical cement coating stored for a long time may have uneven concentration under the deposition phenomenon, the property of the optical cement coating can be obtained only when the display value of the feed back display screen 445 at the feed back pipe 4 is not changed and the reading value of the feed back amount scale 414 is increased at a stable speed. The uniformity of the concentration and viscosity of the optical cement coating can be ensured.
At this time, the viscosity value of the optical cement coating is obtained by the display value of the feed back display screen 445 and the speed of increasing the reading value of the feed back scale 414.
Of course, the relationship arc between the display value of the feed back display screen 445 and the read value increasing speed of the feed back amount scale 414 and the viscosity value of the optical cement coating can be obtained through testing for many times in advance, and the relationship arc is stored, and when the relationship arc is detected, the display value of the feed back display screen 445 and the read value increasing speed of the feed back amount scale 414 are directly obtained, so that the viscosity value of the optical cement coating can be obtained, and the optical cement coating is operated in a simple manner without being controlled by professional personnel.
In addition, once the viscosity value of the optical cement coating is obtained, compared with the viscosity value requirement of the optical cement coating which needs to be output, the optical cement raw material (solute) can be properly added at the feeding port to increase the viscosity or the optical cement solvent (solvent) to reduce the viscosity, and the next step of coating can be carried out until the viscosity value of the optical cement coating passing through the return pipe 4 meets the requirement.
At this time, the first valve 42 is closed, the third valve 51 is opened, so that the optical cement coating flows only into the output pipe 5, the optical cement coating is output and used through the discharge pump 31, the discharge pipe 3, the three-way valve 2 and the output pipe 5, and the output of the coating is detected by the output detection part 52 on the output pipe 5.
Here, the output detection part 52 includes an output elastic plate 521 and an output detection plate 524, an output magnetic member 522 is disposed at an end of the output elastic plate 521 far away from the three-way valve 2, an end of the output elastic plate 521 far away from the output magnetic member 522 is fixed to a side wall of the output pipe 5, an end of the output elastic plate 521 near the output magnetic member 522 is connected to the side wall of the output pipe 5 through an output elastic column 523, the output detection plate 524 is a PCB plate disposed in a magnetic field range of the output magnetic member 522, and the output display screen 525 is electrically connected to the output detection plate 524.
The same as the material return detection part 44, the optical cement coating material pushes the obliquely arranged output elastic plate 521 to deform when passing through the output tube 5, so that one end of the output elastic plate 521, which is close to the output magnetic member 522, bends towards the inner wall of the output tube 5, the displacement of the output magnetic member 522 is detected by the PCB output detection plate 524 within the magnetic field range of the output magnetic member 522, an electric signal is generated, and the electric signal is sent to the output display screen 525 for displaying.
Since the viscosity value of the optical cement coating is known, the flow rate of the optical cement coating passing through the outlet pipe 5 can be known directly by outputting the display value on the display screen 525 and the viscosity value of the optical cement coating.
Here, the flow rate of the optical cement coating is calculated based on the flow rate of the optical cement coating and the inner diameter of the delivery pipe 5.
Further, when the first valve 42 is used, the second valve 43 can be opened, and the paint in the feed back cylinder 41 can be pushed into the paint can 1 by pressing the second plate 412 downward, and can be reused.
