Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of measurement and metrology, and relates to a full-automatic calibrating device and method for a flow cup type viscometer, which is an automatic calibrating device and method for calibrating the viscosity of a sample measured by a flow cup type viscometer and the correction coefficient of the viscometer. BACKGROUND

[0002] The flow cup type viscometer is widely used for measuring the viscosity of paint, varnish and adhesive, and is economical, practical and easy to operate. Its working principle is to measure the time of sample flowing out of the viscometer at a certain temperature to represent the viscosity. There are many types of flow cup type viscometers, according to the JJG743-2018 flow cup type viscometer calibration regulation, including the finger pressure type viscometer such as the T-4 cup, the ISO cup series, the Ford cup series, and the measuring cup type viscometer such as the T-1 cup. The Ford cup is mostly used in Europe and the United States, the T-1 cup and the T-4 cup are mostly used in China, and there is also an ISO cup in the international community. The structures of these cups are similar, but the sizes and shapes are different. In order to ensure the accuracy and effectiveness of the measurement results of the flow cup type viscometer, it needs to be calibrated regularly.

[0003] The flow cup type viscometer calibration device includes a temperature measuring device, a constant temperature device and a timer. The calibration method is that the experimenter blocks the bottom end of the flow pipe of the viscometer with a finger or a plug, pours a certain amount of standard viscosity liquid along the inner wall of the flow cup, removes the standard viscosity liquid from the bottom end of the flow cup, starts the timer at the same time, records the actual flow time of the standard viscosity liquid, calculates the correction coefficient of the viscometer according to the actual flow time and the standard flow time, and completes the calibration of the flow cup type viscometer.

[0004] The constant temperature device used for calibrating the flow cup type viscometer is a constant temperature water tank at present, which has a large volume, a long constant temperature time, a low constant temperature efficiency, and the calibration process is manually operated, and the calibration result is mainly affected by the technical level of the operator. In order to improve the calibration efficiency and accuracy of the flow cup type viscometer, it is necessary to change the traditional constant temperature mode, operation mode and timing mode, and develop a new type of automatic constant temperature and calibration device for the flow cup type viscometer. SUMMARY

[0005] The present application aims to solve the above technical problems and provide a device and method for automatically and quickly calibrating the flow cup type viscometer. The technical solution adopted by the present application is as follows:

[0006] An automated calibration device for an outflow cup viscometer, comprising a finger-pressure type viscometer and a measuring cup type viscometer, wherein the automated calibration device includes a housing, in which an embedded computer, a stopper rod simulation component, a mounting bracket and a temperature control component, a finger-pressure simulation component, and a photosensitive component are fixedly installed. The embedded computer is electrically connected to the stopper rod simulation component, the mounting bracket and the temperature control component, the finger-pressure simulation component, and the photosensitive component. The stopper rod simulation component is located above the mounting bracket and the temperature control component, which are located above the photosensitive component. The finger-pressure simulation component... The simulated component is located between the fixed frame and the thermostatic component and the photosensitive component. The outflow cup viscometer is fixedly installed in the fixed frame and the thermostatic component. The stopper rod simulation component automatically seals / opens the outflow hole of the cup viscometer, and the finger pressure simulation component automatically seals / opens the outflow hole of the finger pressure viscometer. The photosensitive component has a detection pool fixedly installed in it, located directly below the outflow hole of the outflow cup viscometer. The finger pressure simulation component avoids the detection pool. The light source module and the detection module are symmetrically fixedly installed on both sides of the detection pool, and the light source module and the detection module are on the same horizontal axis.

[0007] An automated calibration method for an effluent cup viscometer, using the aforementioned automated calibration device for an effluent cup viscometer, includes the following steps:

[0008] Step 1: Install the outflow cup viscometer in the fixed frame and constant temperature assembly, insert a suitable viscometer adjustment plate, and use the embedded computer to control the simulation component to block the outflow orifice of the outflow cup viscometer.

[0009] Step 2: Pour the viscosity liquid into the outflow cup viscometer. The embedded computer controls the fixture and the constant temperature component to heat the viscosity liquid to the required temperature for testing and maintain the constant temperature.

[0010] Step 3: The embedded computer controls the simulation component to open the outlet orifice of the cup viscometer, the viscous liquid begins to flow out, and the embedded computer starts timing.

[0011] Step 4: When the viscous liquid begins to flow through the detection pool, the detection module detects the change in the light source emitted by the light source module. With the continuous flow of viscous liquid, the reading remains relatively stable. When the flow is interrupted, the reading of the detection module fluctuates. The embedded computer identifies this as the viscous liquid flow interruption time and automatically completes the calibration of the outflow cup viscometer based on the flow time of the viscous liquid.

[0012] The beneficial effects of this invention are:

[0013] The temperature is controlled by an automatic temperature control component, which reduces the size of the temperature control device in the existing technology, making it easy to carry and enabling on-site verification. The finger pressure simulation component and the stopper rod simulation component realize the operation of simulating the manual blocking of the viscometer's outlet hole. The automatic reading design of the photosensitive component automates the entire verification process, improves work efficiency, reduces the labor intensity of personnel, and reduces the errors caused by manual operation in traditional verification methods.

Detailed Implementation

[0028] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] like Figure 1 The diagram shown is a structural schematic of the fully automatic calibration device according to an embodiment of the present invention. A fully automatic calibration device for an outflow cup viscometer includes a device housing, in which an embedded computer 1, a stopper rod simulation component 2, a fixing frame and a constant temperature component 3, a finger pressure simulation component 4, and a light sensor component 5 are fixedly installed.

[0030] Embedded computer 1 is used to control the operation of various components in the fully automatic calibration device and acquire calibration data. Embedded computer 1 is electrically connected to the stopcock simulation component 2, the fixing frame and temperature control component 3, the finger pressure simulation component 4, and the photosensitive component 5, respectively. It controls the stopcock simulation component 2, the fixing frame and temperature control component 3, the finger pressure simulation component 4, and the photosensitive component 5 and acquires data through wired or wireless communication. At the same time, embedded computer 1 has a data processing module inside. The data processing module converts the acquired data and status, and then displays the data on the screen and saves it to the data storage module.

[0031] like Figure 2The diagram shown is a schematic representation of the stopper rod simulation assembly according to an embodiment of the present invention. The stopper rod simulation assembly 2 includes: a long-stroke electromagnet 21, an electromagnet fixing plate 22, an electromagnet heat insulation plate 23, a stopper rod clamp 24, and a universal joint 25. The stopper rod simulation assembly 2 is used for automatic calibration of a measuring cup viscometer. The stopper rod 26 is an accessory to the measuring cup viscometer 27, which is fixedly installed in the mounting frame and the thermostatic assembly 3. The upper end of the stopper rod 26 is connected to the universal joint 25, and the lower end of the stopper rod 26 extends into the mounting frame and the thermostatic assembly 3 and faces the outlet hole of the measuring cup viscometer 27. The stopper rod simulation assembly 2 is used to drive the stopper rod 26 to move up and down and automatically block / open the outlet hole of the measuring cup viscometer 27. The electromagnet fixing plate 22 is a structure composed of two side vertical plates and a bottom plate. The two side vertical plates are fixedly connected to the housing of the calibration device, and the two ends of the bottom plate are fixedly connected to the bottom ends of the two side vertical plates. The long-stroke electromagnet 21 is fixedly installed in the cavity formed by the combination of the two side vertical plates and the bottom plate. An electromagnet heat insulation plate 23 is fixedly installed between the long-stroke electromagnet 21 and the two side vertical plates. The electromagnet heat insulation plate 23 is used to prevent the heat generated by the long-stroke electromagnet 21 during operation from being transferred to the device housing. A circular hole is opened at the center of the bottom plate of the electromagnet fixing plate 22. The stopper rod 24 passes through the circular hole. The inner hole of the upper end of the stopper rod 24 is threadedly connected to the lower end of the moving rod of the long-stroke electromagnet 21. The outer diameter of the lower end of the stopper rod 24 is adapted and fixedly connected to the upper end of the universal joint 25. The universal joint 25 is an existing product, such as... Figure 3 The diagram shows a schematic of the universal joint structure according to an embodiment of the present invention. The lower end of the universal joint 25 is fixedly connected to the upper end of the stopper rod 26 by a connecting bolt. The long-stroke electromagnet 21 is connected to the stopper rod 26 through the stopper rod holder 24 and the universal joint 25. When calibrating the measuring cup viscometer 27, the long-stroke electromagnet 21 is activated, causing the stopper rod 26 to move downwards. The stopper rod 26 blocks the outlet hole of the measuring cup viscometer 27, preventing premature outflow when the viscous liquid is poured in. After the viscous liquid is poured in and reaches a constant temperature, the calibration process begins. The long-stroke electromagnet 21 is activated, causing the stopper rod 26 to move upwards, opening the outlet hole of the measuring cup viscometer 27, allowing the viscous liquid to flow out, and the calibration program begins timing. The universal joint 25 is provided, and its orientation can be flexibly adjusted when subjected to external force. With the adjustment of the universal joint 25, the stopper rod 26 can better match the outlet hole of the measuring cup viscometer 27. The long-stroke electromagnet 21 is an existing product, and its control method is existing technology, which will not be elaborated here.

[0032] like Figure 4The diagram shows a structural schematic of the mounting bracket and thermostatic assembly according to an embodiment of the present invention. The mounting bracket and thermostatic assembly 3 is used to fix and support the outflow cup viscometer and maintain a constant temperature between the outflow cup viscometer and the viscous liquid. The mounting bracket and thermostatic assembly 3 is installed in a sealed insulation box. The mounting bracket and thermostatic assembly 3 includes a thermostatic electrical component and a viscometer fixing component. The thermostatic electrical component mainly includes a heating resistor, a platinum resistance thermometer, a semiconductor cooler, a temperature controller, and a solid-state relay. The thermostatic electrical component is electrically connected to an embedded computer 1. The embedded computer 1 controls the thermostatic electrical component to maintain a constant temperature in the sealed insulation box. The installation position and installation structure of the thermostatic electrical component in the sealed insulation box can be flexibly set as needed. The temperature control method of the thermostatic electrical component is existing technology and will not be described in detail here. The viscometer fixing component includes a viscometer fixing bracket 31, an insulation shell 32, a viscometer fixing cover 33, a viscometer adjusting base 34, and a viscometer adjusting plate 35. The viscometer fixing bracket 31 has a cubic structure, as shown in the diagram. Figure 5 The diagram shown is a structural schematic of the viscometer mounting bracket according to an embodiment of the present invention. A circular groove is formed in the middle of the viscometer mounting bracket 31. The viscometer adjustment base 34 is placed in the circular groove of the viscometer mounting bracket 31. The groove is the placement position for the viscometer, which is placed on the viscometer adjustment base 34. A viscometer mounting cover 33 is fixedly installed on the upper surface of the viscometer mounting bracket 31. Two heat-insulating shells 32 are symmetrically fixedly installed on the viscometer mounting cover 33. A semi-circular arc is formed on one side of the two heat-insulating shells 32 to allow the plug rod 26 to pass through. The cooperation between the viscometer mounting cover 33 and the viscometer mounting bracket 31 ensures the integrity of the viscometer mounting assembly and also forms a limiting space for the viscometer adjustment plate 35. Figure 6 The diagram shown is a structural schematic of the viscometer fixing cover according to an embodiment of the present invention. A protrusion is provided on one side of the viscometer fixing cover 33 for easy gripping and installation. A notch is provided on the side of the viscometer fixing cover 33 away from the protrusion, and a circular hole is provided to accommodate the outflow cup-type viscometer. The viscometer is stably placed inside the viscometer mounting bracket 31. A removable viscometer adjustment plate 35 is designed. A sliding groove is provided on the viscometer mounting bracket 31 to accommodate the viscometer adjustment plate 35. The viscometer adjustment plate 35 is movably installed between the viscometer mounting bracket 31 and the viscometer fixing cover 33. Figure 7The diagram shown is a structural schematic of the viscometer adjustment plate according to an embodiment of the present invention. The viscometer adjustment plate 35 has a circular hole that mates with the upper part of the viscometer, and a square groove for easy pulling. After the viscometer is placed in the circular groove of the viscometer holder 31, the viscometer adjustment plate 35 is inserted into the sliding groove of the viscometer holder 31 to fix the viscometer. Because there are many types of viscometers with different heights, several viscometer adjustment plates 35 of different thicknesses are designed to ensure that the vertical position of the viscometer is fixed and does not wobble after it is placed in the viscometer holder 31. To prevent the bottom of the viscometer from shifting horizontally, a viscometer adjustment base 34 is provided. The viscometer adjustment base 34 is a double-layered ring structure with a certain thickness, which mates with the bottom of the viscometer. Figure 8 The diagram shown is a structural schematic of the viscometer adjustment base according to an embodiment of the present invention. First, the viscometer adjustment base 34 is placed in the circular groove of the viscometer mounting bracket 31. Then, the viscometer is placed inside, with its bottom inserted into the double-layered ring structure of the viscometer adjustment base 34 to fix its position. When calibrating the viscometer, the viscometer is placed in the circular groove of the viscometer mounting bracket 31, with its bottom inserted into the viscometer adjustment base 34. After placement, a suitable viscometer adjustment plate 35 is inserted into the gap at the upper end of the viscometer mounting bracket 31.

[0033] like Figure 9 The diagram shown is a schematic representation of the acupressure simulation component according to an embodiment of the present invention. The acupressure simulation component 4 comprises a short-stroke electromagnet 41, an electromagnet movement rod limiting component 42, an electromagnet fixing plate 43, an acupressure clip 44, an acupressure fixing shaft 45, and an acupressure simulation rubber component 46. The acupressure simulation component 4 is used for the automatic calibration of the acupressure viscometer 47. The acupressure simulation component 4 simulates manual operation to automate the sealing / opening of the acupressure viscometer 47's outflow orifice. The electromagnet fixing plate 43 is bolted to the inclined mounting plate 56 of the photosensitive component 5, and the short-stroke electromagnet 41 is bolted to the electromagnet fixing plate 43. The design of the electromagnet fixing plate 43 ensures that the short-stroke electromagnet 41 moves along a 45-degree angled inclined plane. An electromagnet movement rod limiting component 42 is fixedly installed on the side of the short-stroke electromagnet 41 away from the electromagnet fixing plate 43. The purpose of the electromagnet movement rod limiting component 42 is to restrict the direction of the movement rod of the short-stroke electromagnet 41, preventing the movement rod from deviating during movement and thus failing to achieve the sealing effect of the finger pressure component. Figure 10The diagram shown is a structural schematic of the electromagnet moving rod limiting component according to an embodiment of the present invention. The electromagnet moving rod limiting component 42 is provided with a limiting groove for the moving rod of the short-stroke electromagnet 41. The electromagnet moving rod limiting component 42 and the short-stroke electromagnet 41 are fixedly connected as one unit through fasteners and fixing holes. One end of a long bolt is fixedly connected to the moving rod of the short-stroke electromagnet 41, and the other end of the long bolt is inserted into the limiting groove of the electromagnet moving rod limiting component 42, ensuring that the moving rod of the short-stroke electromagnet 41 moves along the limiting groove of the electromagnet moving rod limiting component 42.

[0034] like Figure 11 The diagram shown is an assembly schematic of the acupressure fixing shaft according to an embodiment of the present invention. The function of the acupressure clip 44 is to connect the moving rod of the short-stroke electromagnet 41 with the acupressure fixing shaft 45. The lower end inner hole of the acupressure clip 44 is threadedly fixed to the moving rod of the short-stroke electromagnet 41. The upper end inner hole of the acupressure clip 44 is axially fixed to one end of the acupressure fixing shaft 45. The other end of the acupressure fixing shaft 45 is fitted with the acupressure simulation rubber part 46. The acupressure simulation rubber part 46 simulates acupressure, and the movement of the acupressure simulation rubber part 46 blocks / opens the outlet hole of the acupressure viscometer 47. The finger pressure simulation component 5 operates in a 45° direction. When calibrating the finger pressure viscometer 47, the short-stroke electromagnet 41 is activated, causing the finger pressure simulation rubber component 46 to move upward in a 45° direction, thereby sealing the outlet hole of the finger pressure viscometer 47 and preventing the viscous liquid from leaking out. At the start of the calibration process, viscous liquid is poured into the finger pressure viscometer 47, and the short-stroke electromagnet 41 moves downward in a 45° direction. The finger pressure simulation rubber component 46 quickly leaves the outlet hole of the viscometer, and the viscous liquid begins to flow out.

[0035] like Figure 12 The diagram shown is an assembly schematic of the photosensitive component according to an embodiment of the present invention; as shown Figure 13The diagram shown is a structural schematic of the photosensitive component mounting bracket according to an embodiment of the present invention. The photosensitive component 5 is used to sense the flow of viscous liquid and realize automatic timing. It consists of a light source module 52, a detection module 53, a detection pool 51, a photosensitive component mounting bracket 54, and a photosensitive component cover 55. The upper part of the photosensitive component mounting bracket 54 is a box structure with an open upper side. A support plate is provided on one side of the lower part of the photosensitive component mounting bracket 54. The bottom end of the support plate is fixedly installed on the lower side of the device housing. The upper end of the support plate is integrally formed with the box structure. An inclined mounting plate 56 is provided on one side of the support plate, and the inclined mounting plate 56 has an inclination angle of 45°. The detection pool 51 is fixedly installed inside the box structure. The detection pool 51 is located directly below the outlet hole of the flow cup viscometer. The light source module 52 and the detection module 53 are symmetrically fixedly installed on both sides of the detection pool 51. The light source module 52 and the detection module 53 are on the same horizontal axis. The detection pool 51 is made of a light-transmitting material. The light source module 52 and the detection module 53 are fixedly installed on both sides of the detection pool 51, ensuring that the light source module 52 and the detection module 53 are on the same axis. The detection pool 51 is designed as a flow space for the viscosity liquid to be tested, preventing the liquid from flowing into the instrument and contaminating the internal modules when it deviates. A photosensitive component cover 55 is bolted to the upper part of the housing structure. The photosensitive component cover 55 has a first through hole corresponding to the position of the detection pool 51, and a second through hole for the finger pressure clip 44 to pass through. The viscosity liquid flows into the detection pool 51 through the first through hole. The light source module 52 and the detection module 53 are existing products and will not be described in detail here. When the viscosity liquid falls freely into the detection pool 51, the detection module 53 can sense the signal change of the light source module 52, and the embedded computer 1 starts or stops timing. The inclined mounting plate 56 is designed with a 45-degree angle to ensure the movement direction of the short-stroke electromagnet 41. The purpose of the cover 55 for the photosensitive component is to prevent viscous liquid from flowing into the instrument and to prevent dust. Four mounting holes are included for easy fixation to the photosensitive component mounting bracket 54. The working principle of the photosensitive component 5 is as follows: the light source module 52 emits light of a certain wavelength, which passes through the detection cell 51. When no viscous liquid flows through, the reading of the detection module 53 remains relatively stable. When viscous liquid flows through, the reading of the detection module 53 changes abruptly due to the absorption of light by the viscous liquid. With continuous flow of viscous liquid, the reading remains relatively stable. When a flow interruption occurs, the reading of the detection module 53 fluctuates. The embedded computer 1 identifies this as the viscous liquid flow interruption time and automatically completes the calibration of the outflow cup viscometer based on the flow time of the viscous liquid.

[0036] An automated calibration method for an effluent cup viscometer, using the aforementioned automated calibration device for an effluent cup viscometer, includes the following steps:

[0037] Step 1: Install the outflow cup viscometer in the fixed frame and constant temperature assembly 3, insert the appropriate viscometer adjustment plate 35, and the embedded computer 1 controls the simulation component to block the outflow hole of the outflow cup viscometer.

[0038] If it is a measuring cup viscometer 27, the measuring cup viscometer 27 is fixedly installed in the fixture and the constant temperature component 3, and the stopper rod 26 attached to the measuring cup viscometer 27 is installed on the stopper rod simulation component 2. The embedded computer 1 controls the action of the stopper rod simulation component 2, and the stopper rod 26 moves downward to block the outflow hole of the measuring cup viscometer 27.

[0039] If the finger pressure viscometer 47 is being calibrated, the finger pressure viscometer 47 is fixedly installed in the mounting bracket and the constant temperature component 3. The embedded computer 1 controls the finger pressure simulation component 4 to move upward and block the outflow hole of the finger pressure viscometer 47.

[0040] Step 2: Pour the viscosity liquid into the outflow cup viscometer. The embedded computer 1 controls the operation of the fixing frame and the constant temperature component 3 to heat the viscosity liquid to the temperature required for the test and maintain the constant temperature.

[0041] Step 3: The embedded computer 1 controls the simulation component to open the outlet orifice of the cup viscometer, and the viscous liquid begins to flow out. The embedded computer 1 then starts timing.

[0042] If it is a measuring cup viscometer 27, the embedded computer 1 controls the action of the stopper rod simulation component 2, and the stopper rod 26 moves upward to open the outlet hole of the measuring cup viscometer 27, and the viscous liquid flows out.

[0043] If the finger pressure viscometer 47 is being calibrated, the embedded computer 1 controls the finger pressure simulation component 4 to move downward, opening the outlet hole of the finger pressure viscometer 47, and the viscous liquid flows out.

[0044] Step 4: When the viscous liquid begins to flow through the detection pool 51, the detection module 53 detects the change in the light source emitted by the light source module 52. With the continuous flow of viscous liquid, the reading remains relatively stable. When the flow is interrupted, the reading of the detection module 53 fluctuates. The embedded computer 1 identifies this as the time of viscous liquid flow interruption. The embedded computer 1 automatically completes the calibration of the outflow cup viscometer based on the flow time of the viscous liquid.
