Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0030] The following describes in detail an AB type potting compound preparation device according to an embodiment of the present invention with reference to the accompanying drawings.

[0031] like Figure 1-3 As shown, the AB type potting glue modulation device according to an embodiment of the present invention includes: a mounting base 7, two storage components 1, a mixing component 8, and a guide component; one storage component 1 is used to output component A materials, and the other storage component 1 is used to output component B materials. The feed port of the storage component 1 is connected to the supply barrel through a first pipe, the storage component 1 is used to temporarily store component materials, automatically replenish component materials and pre-treat component materials, the discharge port of the storage component 1 is connected to the mixing component 8 through a second pipe, the mixing component 8 is used to evenly mix component A materials and component B materials, the first pipe and the second pipe are both connected to the guide component, and the guide component is used to introduce the component materials in the storage component 1 into the mixing component 8 or to introduce the component materials in the supply barrel into the storage component 1.

[0032] In this embodiment, by sharing a guide component, the output and replenishment of the component materials inside the storage component 1 are controlled, thereby realizing miniaturization of the equipment. At the same time, after the mixing component 8 supplies sufficient component materials into the mixing component 8, the mixing component 8 mixes the component materials inside it. During this process, the guide component can use the spare time to replenish the component materials inside the storage component 1, thereby realizing the replenishment of component materials during spare time and saving time costs.

[0033] The diversion component includes a first solenoid valve 4, a second solenoid valve 5 and an output power component; the discharge end of the first solenoid valve 4 is connected to the conveying power component, one feed end of the first solenoid valve 4 is connected to the feeding barrel, and the other feed end of the first solenoid valve 4 is connected to the discharge port of the storage component 1, the feed end of the second solenoid valve 5 is connected to the conveying power component, one discharge end of the second solenoid valve 5 is connected to the mixing component 8, and the other discharge end of the second solenoid valve 5 is connected to the feed port of the storage component 1. The diameter of the discharge port is larger than the diameter of the feed port, and heaters 3 are provided at both the discharge port and the feed port.

[0034] In this embodiment, the first solenoid valve 4 and the second solenoid valve 5 are used to control the flow direction of the component materials, and the heater 3 is used to heat the component materials to improve their fluidity. The heater 3 is provided with a temperature sensor, and the temperature sensor is used to detect the temperature of the flowing component materials, thereby adjusting the heating condition of the heater 3. In addition, when the temperature sensor at the discharge port detects that the temperature of the outflowing component materials is lower than the required temperature, the second solenoid valve 5 closes one end connected to the mixing component 8 and opens one end connected to the inlet. At this time, the component materials flowing out through the discharge port are heated by the heater 3 at the discharge port and flow back into the lower cylinder 19. When passing through the inlet, secondary heating is achieved to ensure the temperature of the component materials and avoid poor flow caused by too low a temperature of the component materials, resulting in uneven mixing. At the same time, since the diameter of the inlet is smaller than the outlet Material port, therefore, in the above cycle, the pressure of the component material increases when entering the material feed port, and the component material rushing into the lower cylinder 19 impacts the component material inside the lower cylinder 19. The component material inside the lower cylinder 19 is accelerated after being impacted, and the fast-flowing component materials mix with each other, making the temperature of the component material inside the lower cylinder 19 more uniform, so that when the component material flows out of the material discharge port, the heater 3 at the material discharge port controls the temperature of the component material again to improve the accuracy of temperature control, and the device adopts an internal circulation method to suck the material from the bottom of the lower cylinder 19 and backwash it back to the lower cylinder 19 through the pipeline, and uses the diameter of the material feed port to be smaller than the material discharge port, so that there is a certain pressure difference and flow rate difference between the material discharge port and the material feed port on the stirring circuit, which can effectively improve the stirring method of the radial vortex turbulence of the traditional stirring mechanism, which causes uneven stirring at the bottom of the barrel. The first solenoid valve 4 and the second solenoid valve 5 in the device provide the device with three routes: a potting and mixing route, a circulating stirring route, and an external silo feeding route. These three routes share some pipelines and use the conveying power component as the driving force output source of the material flow. Compared with traditional equipment of this type, the feeding pump and related equipment can be eliminated, which further simplifies the device and effectively realizes the miniaturization of the equipment. Through the logical control of the first solenoid valve 4 and the second solenoid valve 5, the three routes can be switched arbitrarily, and the device has the three functions of potting and mixing, circulating stirring and automatic feeding.

[0035] The material storage assembly 1 includes: a lower cylinder body 19 and an upper cylinder body 16; the feed port and the discharge port are both provided on the lower cylinder body 19, the lower end side surface of the upper cylinder body 16 is slidingly connected to the inner surface of the lower cylinder body 19, and an exhaust pipe is provided in the upper cylinder body 16, one end of the exhaust pipe is connected to the exhaust valve 13, and the other end of the exhaust pipe is connected to the lower cylinder body 19.

[0036] In this embodiment, the upper cylinder 16 is pushed up and down to make the upper cylinder 16 vacuum and pressurize the lower cylinder 19. During this process, the air in the component materials in the lower cylinder 19 can be separated from the component materials, and in the process of the upper cylinder 16 pressurizing the lower cylinder 19, the gas inside the lower cylinder 19 is discharged from the lower cylinder 19 along the exhaust pipe, avoiding the air and the component materials being transported into the mixing component 8 together, resulting in an imbalance in the ratio of the component materials, and improving the accuracy of the ratio. When the viscosity of one of the component materials is large, there will be a certain flow rate difference and pressure difference between the AB materials. At this time, the up and down movement of the upper cylinder 16 can be used to make the upper cylinder 16 pressurize and accelerate downward or the upper cylinder 16 decelerate upward The pressure reduction speed action balances the material flow rate of the AB pipeline according to the actual situation. Since the lower cylinder body 19 does not need to store a large amount of component materials, its volume is much smaller than that of the traditional mixing barrel, which makes the gas in the component materials precipitate faster. When the upper cylinder body 16 descends, as the volume of the negative pressure chamber of the lower cylinder body 19 becomes smaller, the pressure of the gas precipitated in the component materials will increase accordingly. At this time, the exhaust valve 13 automatically opens after reaching the set pressure and removes the precipitated gas. The vacuum function is achieved through multiple actions. Compared with traditional equipment, this design can eliminate the vacuum pump and related pipelines, greatly simplify the device, and make the equipment miniaturized. The exhaust pipe increases the precipitation path during the gas precipitation process, which is convenient for avoiding some component materials from flowing out of the exhaust valve 13.

[0037] A first mounting plate 11 and a second mounting plate 17 are provided on the mounting base 7. The second mounting plate 17 is located between the first mounting plate 11 and the mounting base 7. The lower cylinder body 19 is fixed on the second mounting plate 17. A plurality of cylindrical guide rods 15 are provided on the first mounting plate 11. The upper cylinder body 16 includes an upper cover 14. The upper cover 14 is provided with ball bushings of the same number as the cylindrical guide rods 15. The plurality of cylindrical guide rods 15 respectively pass through the centers of the plurality of ball bushings. The storage assembly 1 also includes a first motor 12. The first motor 12 is mounted on the first mounting plate 11. The output end of the first motor 12 passes through the first mounting plate 11 facing the direction of the second mounting plate 17. A lead screw is installed on the output end of the first motor 12. A threaded hole engaged with the lead screw is opened at the center of the upper surface of the upper cylinder body 16, and the lead screw extends into the interior of the upper cylinder body 16 through the threaded hole.

[0038] In this embodiment, a plurality of cylindrical guide rods 15 are used to limit the moving direction of the upper cylinder body 16 , and the first motor 12 is used to output power. The first motor 12 is combined with the plurality of cylindrical guide rods 15 to control the moving direction of the upper cylinder body 16 .

[0039] The delivery power assembly includes a variable valve 6 and a second motor 2. The second motor 2 is mounted on a mounting base 7. The output shaft of the second motor 2 is connected to the variable valve 6 via a keyway.

[0040] In this embodiment, the second motor 2 is a speed-regulating motor. The speed-regulating motor serves as the output unit of the driving force. The speed-regulating motor has a large speed-regulating range and can realize stepless speed regulation. The output flow of the variable valve 6 can be adjusted to realize multi-speed output adjustment of the output value. In this way, multiple modes can be switched according to the characteristics of the component materials and the actual process requirements and batch conditions of the potting operation. Therefore, the combination of the speed-regulating motor and the variable valve 6 can realize precise output control of the component quantity flow rate and multiple combinations to control the conveying speed of the component materials.

[0041] A sealing ring 18 is installed on the outer wall of the lower end of the upper cylinder body 16 to facilitate the upper cylinder body 16 to effectively vacuum or pressurize the lower cylinder body 19.

[0042] The equipment adopts automatic actuators and realizes automatic control of the entire process through PLC programming, and cooperates with relevant sensors to realize parameter monitoring of the entire process.

[0043] A method for using an AB type potting adhesive preparation device, using the above-mentioned AB type potting adhesive preparation device, comprises the following steps:

[0044] S1. When sufficient component materials enter the mixing assembly 8 for the mixing process, the first solenoid valve 4 switches to the feed end and the second solenoid valve 5 switches to the discharge end, so that the feed barrel is connected to the lower cylinder 19. The guide assembly guides the component materials in the feed barrel into the lower cylinder 19. This allows the automatic replenishment of component materials during idle time. In addition, since the component materials can be replenished at any time, the lower cylinder 19 can be set to a relatively small volume, realizing miniaturization of the equipment.

[0045] S2. The first motor 12 rotates to move the upper cylinder 16 upward. At this time, the lower cylinder 19 is in a vacuum state, and the gas in the component materials in the lower cylinder 19 is preliminarily separated from the component materials. The first motor 12 rotates in the opposite direction to drive the upper cylinder 16 to move downward. The gas separated in the lower cylinder 19 is forced to be compressed downward, and the gas in the lower cylinder 19 is discharged through the exhaust valve 13. This operation is repeated to achieve the effect of automatic vacuuming. At the same time, due to the small volume of the lower cylinder 19, the gas separation speed is faster.

[0046] S3. The heater 3 is in an open state when the feed barrel is connected to the lower cylinder 19, and the component materials fed into the lower cylinder 19 are preliminarily heated. When the guide component guides the component materials into the mixing component 8, the heater 3 controls the temperature of the component materials passing through. The heater 3 is used to heat and increase the temperature of the component materials to improve their fluidity. A temperature sensor is provided on the heater 3, and the temperature sensor is used to detect the temperature of the flowing component materials, thereby adjusting the heating condition of the heater 3. When the temperature sensor at the discharge port detects that the temperature of the outflowing component materials is lower than the required temperature, the second solenoid valve 5 closes one end connected to the mixing component 8 and opens one end connected to the feed port, forming a circulating stirring route to achieve stirring and heating of the component materials.
