Description

Technical Field

[0001] This utility model relates to the field of potting compound production technology, specifically a constant temperature mixing device for potting compound production. Background Technology

[0002] Potting compounds, also known as electronic adhesives, are liquid polyurethane composites mechanically or manually injected into devices containing electronic components and circuits. They then cure at room temperature or under heating conditions to become high-performance thermosetting polymer insulating materials. Potting compounds play an irreplaceable role in protecting electronic components. They prevent electronic components from being affected by mechanical stress, chemical corrosion, humidity, dust, and other environmental factors, ensuring the stability and reliability of electronic components. During the mixing and preparation of potting compounds, due to their easy solidification characteristics, constant temperature control is required for the substances in the mixing tank. However, existing constant temperature tanks typically use bottom heating, which leads to uneven temperature distribution (colder at the top and hotter at the bottom) and poor mixing quality. Therefore, a constant temperature mixing device for potting compound production is needed.

[0003] According to application number CN201821599244.6, a potting compound mixing device includes a body, a base installed at the bottom of the body, a water pump installed on the outer wall of the body, a water outlet end of the water pump connected to a water guide pipe, a nozzle installed at one end of the water guide pipe, a mixing chamber provided inside the body, an inlet pipe provided at the top of the mixing chamber, an outlet pipe installed on the side wall of the mixing chamber, a stirring rod provided inside the mixing chamber, and an electric motor installed at one end of the stirring rod.

[0004] The aforementioned document describes heating the side walls of the machine body using a circulating water bath, allowing for simultaneous heating of a larger area of ​​the internal potting compound. However, it cannot heat the potting compound in the center of the machine body, resulting in an issue of internal cooling and external heating during mixing. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a constant temperature mixing device for potting compound production, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A constant temperature mixing device for potting compound production includes a mixing tank, a tank cover disposed on top of the mixing tank, a stirring rod disposed inside the mixing tank, a plurality of detection frames sleeved on the outside of the stirring rod, a temperature control component mounted on the detection frames, and a driving component disposed on top of the tank cover.

[0008] Preferably, the stirring rod includes a first bearing sleeve disposed at the bottom of the inside of the stirring tank, a second bearing sleeve passing through the middle of the top of the tank cover, and an array of stirring blades sleeved in the middle of the stirring rod.

[0009] Preferably, the detection frame includes a third bearing sleeve fitted on the outside of the stirring rod, a connecting rod connected at one end to the third bearing sleeve and at the other end to the inner wall of the stirring tank, and multiple sleeves disposed on the surface of the connecting rod.

[0010] Preferably, the temperature control component includes an annular thermocouple tube passing through the sleeve inside the connecting rod, multiple temperature sensors disposed on the surface of the connecting rod, and a temperature controller disposed outside the mixing tank.

[0011] Preferably, the temperature controller includes a support base at the bottom, a display screen on the surface of the temperature controller, and a control panel below the display screen.

[0012] Preferably, the driving component includes a flange disposed on the top of the second bearing sleeve, a right-angle reducer disposed on the top of the flange and whose output end is connected to the top of the stirring rod, and a drive motor whose execution end is connected to the input end of the right-angle reducer.

[0013] Preferably, the mixing tank includes a feed pipe located at the top of the tank cover, a discharge pipe located at the bottom of the mixing tank, a solenoid valve located at the output end of the discharge pipe, handles located at both ends of the top of the tank cover, and a support frame located at the bottom of the mixing tank.

[0014] In summary, this technical solution has the following main advantages:

[0015] In this embodiment, by setting multiple layers of annular thermocouple tubes alternating with the stirring blades inside the mixing tank, various areas inside the mixing tank can be heated simultaneously, so that there is no significant temperature difference in the potting compound in different areas of the mixing tank. Through multiple temperature sensors on the surface of the connecting rod and a temperature controller, the temperature of the potting compound can be controlled at the most suitable state, which greatly improves the mixing quality.

[0016] By designing the drive components as detachable modules, the tank lid can be easily opened to inspect, maintain, and clean the internal components of the mixing tank, preventing problems such as material blockage and mechanical damage after repeated use. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example

[0025] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 4 and 5, a constant temperature mixing device for potting compound production includes a mixing tank 10, a tank cover 11 disposed on the top of the mixing tank 10, a stirring rod 12 disposed inside the mixing tank 10, multiple detection frames 13 sleeved on the outside of the stirring rod 12, a temperature control component 14 mounted on the detection frames 13, and a drive component 15 disposed on the top of the tank cover 11. The drive component 15 includes a flange 151 disposed on the top of a second bearing sleeve 122, a right-angle reducer 152 disposed on the top of the flange 151 and whose output end is connected to the top of the stirring rod 12, and a drive motor 153 whose execution end is connected to the input end of the right-angle reducer 152. The stirring rod 12 includes a first bearing sleeve 121 disposed at the bottom of the mixing tank 10, a second bearing sleeve 122 passing through the middle of the top of the tank cover 11, and an array of stirring blades 123 sleeved in the middle of the stirring rod 12.

[0026] It should be noted that multiple stirring blades 123 and multiple detection frames 13 are alternately arranged on the stirring rod 12 from top to bottom. The stirring blades 123 and the stirring rod 12 are fixedly connected together, while the detection frames 13 are rotatably connected to the stirring rod 12 through the third bearing sleeve 131. Inside the mixing tank 10, the larger the radius of the area, the larger the rotation radius of the stirring blades 123, which facilitates the stirring of the potting compound in each area.

[0027] Furthermore, before using this device, the drive motor 153 is connected to the right angle reducer 152, the output end of the right angle reducer 152 is connected to the stirring rod 12, and the right angle reducer 152 is fixed to the top of the tank cover 11 through the flange 151.

[0028] Furthermore, when it is necessary to mix and stir the potting compound, the drive motor 153 starts, and drives the stirring rod 12 to rotate around the first bearing sleeve 121 and the second bearing sleeve 122 as the axis through the right angle reducer 152, thereby driving the stirring blades 123 at each stage to stir and mix the potting compound.

[0029] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figure 5, the detection frame 13 includes a third bearing sleeve 131 sleeved on the outside of the stirring rod 12, a connecting rod 132 connected to the third bearing sleeve 131 at one end and connected to the inner wall of the stirring tank 10 at the other end, and multiple sleeves 133 on the surface of the connecting rod 132; the temperature control component 14 includes an annular thermocouple tube 141 passing through the sleeves 133 and inside the connecting rod 132, multiple temperature sensors 142 on the surface of the connecting rod 132, and a temperature controller 143 on the outside of the stirring tank 10; the temperature controller 143 includes a support base 1431 at the bottom, a display screen 1432 on the surface of the temperature controller 143, and a control panel 1433 below the display screen 1432.

[0030] It should be noted that the connecting rod 132 contains cables for transmitting signals and power supply. Part of the connecting rod 132 extends out of the mixing tank 10 and is connected to the temperature controller 143. The annular thermocouple tube 141 and the temperature sensor 142 are arranged on the connecting rod 132 at appropriate intervals to facilitate simultaneous heating and accurate monitoring of the entire internal space of the mixing tank 10. Each annular thermocouple tube 14 can be individually controlled in temperature so that when a temperature difference occurs in a certain area, adjusting a certain annular thermocouple tube 14 can compensate for the temperature difference in that area.

[0031] Furthermore, when mixing the potting compound, the appropriate mixing temperature is set through the control panel 1433, and the various annular thermocouple tubes 141 in the sleeve 133 heat up together to heat the potting compound inside the mixing tank 10 to a suitable temperature.

[0032] Furthermore, multiple temperature sensors 142 continuously detect the temperature of various areas inside the mixing tank 10 and display the temperature of each area on the display screen 1432;

[0033] Furthermore, when the display screen 1432 shows a significant temperature difference in a certain area, the temperature in that area can be compensated by adjusting the annular thermocouple tube 141 responsible for heating that area through the control panel 1433.

[0034] Please refer to the attached document carefully. Figure 1 ,2 As shown in Figure 3, the mixing tank 10 includes a feed pipe 101 located at the top of the tank cover 11, a discharge pipe 102 located at the bottom of the mixing tank 10, a solenoid valve 103 located at the output end of the discharge pipe 102, handles 104 located at both ends of the top of the tank cover 11, and a support frame 105 located at the bottom of the mixing tank 10.

[0035] It should be noted that the right-angle reducer 152 and the top of the stirring rod 12 are joined together by a meshing structure. The right-angle reducer 152 is fixed to the top of the tank cover 11 by the flange 151. When maintenance is required, the tank cover 11 can be lifted upwards to disengage the right-angle reducer 152 from the top of the stirring rod 12, making it easy to remove the cover.

[0036] Furthermore, when potting compound needs to be added, the potting compound can be added into the mixing tank 10 through the feed pipe 101 manually or by external machinery;

[0037] Furthermore, when the mixing is complete and discharge is required, the solenoid valve 103 opens, and the mixed potting compound flows out from the discharge pipe 102 at the bottom of the mixing tank 10.

[0038] Furthermore, when it is necessary to inspect, maintain or clean the components, loosen the components that are responsible for fixing the can lid 11, and lift the can lid 11 upwards using the handle 104, so that the right angle reducer 152 can be disengaged from the stirring rod 12 and the entire can lid 11 can be removed.

[0039] The working principle of this utility model is as follows:

[0040] First, before using this device, connect the drive motor 153 to the right-angle reducer 152, connect the output end of the right-angle reducer 152 to the stirring rod 12, and fix the right-angle reducer 152 to the top of the tank cover 11 via the flange 151. When it is necessary to mix and stir the potting compound, start the drive motor 153, which drives the stirring rod 12 to rotate around the first bearing sleeve 121 and the second bearing sleeve 122 as the shaft through the right-angle reducer 152, thereby driving the stirring blades 123 to stir and mix the potting compound. When stirring the potting compound, set a suitable mixing temperature through the control panel 1433. The various annular thermocouple tubes 141 in the sleeve 133 heat up together, heating the potting compound inside the mixing tank 10 to a suitable temperature. Multiple temperature sensors 142 continuously monitor the temperature inside the mixing tank 10. The temperature of each area is controlled and displayed on the display screen 1432. When the display screen 1432 shows a significant temperature difference in some areas, the annular thermocouple tube 141 responsible for heating that area can be adjusted through the control panel 1433 to compensate for the temperature difference in that area. When potting compound needs to be added, it can be added into the mixing tank 10 through the feed pipe 101 manually or by external machinery. When the mixing is complete and the material needs to be discharged, the solenoid valve 103 is opened, and the mixed potting compound flows out from the discharge pipe 102 at the bottom of the mixing tank 10. When the components need to be inspected, maintained, or cleaned, the components that fix the tank cover 11 are loosened, and the tank cover 11 is lifted upwards through the handle 104, so that the right angle reducer 152 can be disengaged from the stirring rod 12 and the entire tank cover 11 can be removed.

[0041] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
