Description

Technical Field

[0001] This utility model relates to the technical field of thermally conductive adhesive production, and in particular to a device for dispersing and grinding ultra-high thermal conductivity adhesive raw materials. Background Technology

[0002] As the power density of electronic devices continues to increase, the requirements for heat dissipation become increasingly stringent, making ultra-high thermal conductivity adhesives a key material. These adhesives typically require a large amount of micron- or nano-sized high thermal conductivity fillers.

[0003] Existing ultra-high thermal conductivity adhesive raw material dispersion and grinding devices, such as the grinding device for producing filled epoxy resin-based high-efficiency thermally conductive adhesive disclosed in utility model patent application number 202320516788.6, mainly include a box body, with a grinding sleeve fixedly connected to the top of the inner cavity of the box body, and a grinding roller arranged inside the grinding sleeve. In use, by starting the motor, the output end of the motor drives gear two, gear belt, gear one and limit block to rotate. The limit block drives the limit groove, transmission shaft and grinding roller to rotate. The grinding roller and grinding sleeve cooperate to grind the material. Start the electric cylinder, and the output end of the electric cylinder drives the rocker plate to rotate counterclockwise around the pin shaft. The rocker plate drives the lifting plate to move upward. The lifting plate drives the grinding roller, transmission shaft and limit groove to move upward.

[0004] However, the grinding process of ultra-high thermal conductivity adhesive raw materials generates a lot of heat, which may lead to a sharp increase in viscosity or gelation. Moreover, the thermal conductivity adhesive raw materials have poor fluidity, making it difficult to flow within the grinding device and easily leaving residues inside. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an ultra-high thermal conductivity adhesive raw material dispersion and grinding device that can not only absorb the heat generated by grinding in a timely manner, thus enhancing the heat dissipation effect of the device and preventing the raw material viscosity from increasing sharply or gelling, but also enhance the flowability of the raw material and facilitate the discharge of the raw material after grinding.

[0006] This utility model discloses a high thermal conductivity adhesive raw material dispersion and grinding device, including a feeding mechanism; it also includes a grinding mechanism, a discharging mechanism, a water supply mechanism, and a reflux mechanism. The grinding mechanism is installed on the feeding mechanism to grind the raw material, the discharging mechanism is installed on the grinding mechanism to accelerate the discharge of the raw material, the water supply mechanism is installed on the feeding mechanism to absorb the heat generated during grinding, and the reflux mechanism is installed on the water supply mechanism to circulate cooling water. The operator feeds the high thermal conductivity adhesive raw material into the feeding mechanism, the grinding mechanism disperses and grinds it, and the ground material is discharged through the discharging mechanism. During the grinding process, the water supply mechanism and the reflux mechanism work together to absorb the heat generated, preventing the temperature inside the feeding mechanism from becoming too high, which could lead to a sharp increase in viscosity or gelation, thus ensuring the grinding effect.

[0007] Preferably, the feeding mechanism includes a cylinder, a partition, a feeding cylinder, a hinge, a sealing cover, and a handle. The bottom end of the cylinder is connected to the ground. The partition is installed inside the cylinder, forming a sandwich between the cylinder and the partition. The partition has an internal cavity. The bottom end of the feeding cylinder is connected to the top end of the partition. The hinge is installed on the feeding cylinder, the sealing cover is installed on the hinge, and the handle is installed on the sealing cover. The operator pulls the handle to open the sealing cover, facilitating the feeding of raw materials through the feeding cylinder into the cavity of the partition. Then, the sealing cover is closed to prevent material volatilization during the grinding process.

[0008] Preferably, the grinding mechanism includes a stator grinding disc, a motor, a dual-output shaft reducer, a first drive shaft, a rotor grinding disc, a first helical blade, and a stirring blade. The stator grinding disc is installed in the cavity of the partition layer. The motor is installed on the cylinder.

The rotor grinding disc is installed on the first drive shaft. A grinding gap is left between the stator grinding disc and the rotor grinding disc. The first helical blade is installed on the first drive shaft, and the stirring blade is installed on the first drive shaft. When the motor is started, the motor drives the first drive shaft to rotate through the dual-output shaft reducer. The first drive shaft drives the rotor grinding disc, the first helical blade, and the stirring blade to rotate. The stirring blade stirs and disperses the raw material, improving its fluidity. The rotation of the first helical blade generates downward pressure, squeezing the raw material into the grinding gap between the stator grinding disc and the rotor grinding disc. The rotor grinding disc cooperates with the stator grinding disc to grind the raw material.

[0009] Preferably, the upper surface of the stator grinding disc is concave; by setting the concave shape, it is convenient for the raw material to enter the gap between the stator grinding disc and the rotor grinding disc, thereby reducing the amount of raw material residue.

[0010] Preferably, the discharge mechanism includes a discharge hopper, a discharge pipe, a second drive shaft, and a second helical blade. The discharge hopper is installed at the bottom of the cavity inside the partition. The top of the discharge pipe is connected to the bottom of the discharge hopper. The second drive shaft is rotatably mounted on the discharge pipe, and the power output end of the dual-output shaft reducer is connected to the power input end of the second drive shaft. The second helical blade is mounted on the second drive shaft. The ground raw material falls into the discharge hopper and is discharged through the discharge pipe. The dual-output shaft reducer drives the second drive shaft to rotate, and the second drive shaft drives the second helical blade to rotate, accelerating the discharge of the raw material.

[0011] Preferably, the water supply mechanism includes a heat dissipation water tank, a water inlet pipe, a water delivery pipe, and a valve.

The operator adds cooling water to the heat dissipation water tank through the water inlet pipe, opens the valve, and the cooling water is delivered to the interlayer through the water delivery pipe to absorb the heat generated by grinding.

[0012] Preferably, the reflux mechanism includes a circulating pump, a pumping pipe, a thermometer, and a return pipe. The bottom end of the circulating pump is connected to the top end of the cylinder. The pumping pipe is installed between the circulating pump and the jacket. The thermometer is installed on the pumping pipe. The return pipe is installed between the circulating pump and the cooling water tank. When the circulating pump is started, it draws cooling water from the jacket through the pumping pipe and delivers the cooling water to the cooling water tank through the return pipe for heat dissipation and circulation, reducing water resource utilization. The temperature of the cooling water is detected by the thermometer, and the cooling water can be replaced when the temperature is too high.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the staff puts the ultra-high thermal conductivity adhesive raw material into the feeding mechanism, the grinding mechanism disperses and grinds it, and the ground material is discharged through the discharge mechanism. During the grinding process, the water supply mechanism and the reflux mechanism work together to absorb the heat generated, so as to avoid the temperature in the feeding mechanism from being too high, which would cause the viscosity to increase sharply or gel, and ensure the grinding effect.
