DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See also Figures 1 to 6 ,The utility model provides a technical solution: a temperature control device for epoxy resin glue of automobile capacitors, including a working unit;

[0037] Specific:

[0038] A temperature control device for epoxy resin glue for automobile capacitors, comprising a working unit; characterized in that the working unit comprises a dispersion container, a temperature control device and a driving device; the dispersion container comprises a barrel 101, a drainage hole 102, and a support frame 103, a large circular hole 104, a middle circular hole 105 and a small circular hole 106 are provided on the top of the barrel 101, the large circular hole 104 is used to install the driving device, the middle circular hole 105 is a liquid inlet hole, a plurality of groups of heating holes 110 are provided on the side of the barrel 101, the heating holes 110 are evenly and equidistantly arranged vertically, the drainage hole 102 is arranged directly below the barrel 101, and the support frame 103 is installed at the bottom of the barrel 101;

[0039] The temperature control device includes a long-rod thermometer 201 and a heater. The long-rod thermometer 201 enters the barrel 101 through the small round hole 106 of the barrel 101, and the heater is installed in the heating hole 110 opened on the side of the barrel 101;

[0040] The driving device includes a motor 301, a transmission 302, a hole cover 303, a stirring rod 304 and a stirring blade 305. One end of the transmission 302 is connected to the output end of the motor 301, and the other end of the transmission 302 is connected to the stirring rod 304. The stirring blade 305 is installed on the stirring rod 304. The hole cover 303 is installed on the large circular hole 104 opened on the top of the barrel 101. The hole cover 303 is provided with a hole. The transmission 302 is fixed on the hole cover 303. The stirring rod 304 enters the inside of the barrel 101 through the hole opened in the hole cover 303. Because the viscosity of the automotive capacitor epoxy resin glue is very high, the transmission 302 is required to increase the torque to improve the stirring ability. At the same time, the axis of the motor 301 and the axis of the stirring rod 304 are not in the same straight line to avoid resonance caused by vibration of the motor 301, thereby preventing the overall instability.

[0041] Specifically, the barrel 101 includes an inner liner 107 and an outer shell 108. The heating holes 110 opened on the side of the barrel 101 are all opened on the outer shell 108, so that the heater can heat the inner liner 107 by heating the medium to avoid direct heating. The viscosity of the epoxy resin glue will decrease with the increase of temperature. Direct heating of the barrel 101 will cause uneven heating and fail to achieve the monitoring effect.

[0042] Specifically, a pressure relief hole 109 is provided on the outer shell 108, so that the gas in the interlayer of the barrel 101 can be discharged after being heated. Heat transfer is a slow process. Failure to provide the pressure relief hole 109 will cause the internal pressure of the interlayer to increase, and the barrel 101 may be deformed in the case of uneven heating.

[0043] Specifically, the interlayer between the inner liner 107 and the outer shell 108 can be filled with insulating material or liquid. Filling the interlayer with insulating material or liquid can improve the heating efficiency. The insulating material or liquid can transfer heat energy evenly, making the heating process smoother, avoiding the situation where the local temperature exceeds the standard due to slow heat transfer from the heater, and making the temperature control more accurate.

[0044] Specifically, the drain hole 102 uses a push-pull valve, which can prevent the valve active area from being blocked by residual epoxy resin glue and causing valve failure. The valve is opened during draining, and the liquid in the cylinder can be discharged from the valve port. After the draining is completed, the valve is closed, and the remaining liquid in the valve port is cleared in time, and the remaining liquid in the cylinder is discharged during the cylinder cleaning step.

[0045] Specifically, the long rod thermometer 201 includes an upper detector 202, a middle detector 203 and a bottom detector 204, which can detect the internal temperature from multiple points to ensure the consistency of the heating temperature in the cylinder. At the same time, the upper detector 202 and the middle detector 203 form an angle with the horizontal plane, which increases the measurement range and makes the obtained measurement value more accurate.

[0046] Specifically, the stirring blade 305 is curved. Since the target product has a high viscosity, improving the stirring efficiency requires considering the contact area between the stirring blade 305 and the product. Therefore, using a curved blade can fully stir to avoid the generation of excessive bubbles. At the same time, large-area stirring is conducive to heat transfer.

[0047] Specifically, the heater placed in the heating hole 110 has a temperature monitoring function, which can adjust the heating temperature in real time. The heating point cooperates with the internal monitoring point to more accurately obtain the specific heating situation, improve the consistency of heating, and the controllability of temperature.
