Description

Technical Field

[0001] This utility model relates to the field of dispersion devices, and in particular to a dispersion device for conductive particles of sealant for electronic components. Background Technology

[0002] The conductive particle dispersion device for electronic component sealants is a specialized piece of equipment used to uniformly disperse conductive particles (such as silver and copper) in sealants (such as epoxy resin and silicone) to ensure conductivity and mechanical stability. It breaks up particle agglomerates through mechanical stirring, ultrasonic vibration, or high shear force, preventing sedimentation or aggregation. It is suitable for high-precision applications such as microelectronic packaging and PCB protection, improving the reliability and conductivity uniformity of electronic components.

[0003] However, the shear pumps equipped in most dispersion units are inconvenient to disassemble and maintain. Long-term shearing of colloids results in a large accumulation of residue at the pump inlet, requiring timely disassembly, maintenance, or replacement. The difficulty of disassembly affects the production efficiency of the unit. In addition, the high-speed dispersion paddles equipped in the unit are also difficult to disassemble and assemble quickly. The large amount of residue on the surface will affect the dispersion efficiency and quality of conductive particles in the colloid, thereby reducing the practicality of the unit.

[0004] Therefore, those skilled in the art have provided a device for dispersing conductive particles of sealant for electronic components to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a conductive particle dispersion device for sealant in electronic components. The device involves inserting one end of a connecting hose into one end of a shear pump. The fixed part of the connecting hose and its sliding rod are aligned with the mounting plate of the shear pump. The sliding rod is then pressed down, causing its locking rod and hook to pass through a through groove on the mounting plate. The hook is then twisted 90 degrees and pulled upwards, engaging with the locking groove. Finally, the fixing screw is twisted, using the rotating frame as a fulcrum, causing the insert to pass through the upper end of the fixed part and engage with the sliding rod through the insertion port. This facilitates the disassembly and maintenance of the shear pump and improves the device's practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A conductive particle dispersion device for electronic component sealant includes a support frame, a receiving plate, a shear pump, an ultrasonic transducer, a tank, a tank cover, and a servo motor. The upper surface of the receiving plate is provided with a convenient maintenance mechanism. The output end of the servo motor is fixedly connected to a quick-release mechanism. The convenient maintenance mechanism includes a valve, one end of which is provided with a connecting hose. One end of the connecting hose is fixedly connected to multiple fixing parts. A rotating frame is fixedly connected to both ends of the upper surface of each fixing part. A sliding rod is slidably connected to the middle of one side surface of each fixing part. An insertion port is opened in the middle of the outer wall of the sliding rod. A locking rod is rotatably connected to one end of the sliding rod. A hook rod is fixedly connected to one end of the locking rod. A fixing screw is threadedly connected to the middle of the upper surface of the rotating frame. A cylinder is fixedly connected to the lower end of the fixing screw. Multiple mounting plates are fixedly connected to one end of the shear pump. A through groove is opened in the middle of one side surface of each mounting plate. Locking slots are opened at both ends of one side surface of each mounting plate. Through the above technical solution, the device connects one end of the connecting hose to one end of the shear pump. At this time, the fixed part of the connecting hose and the sliding rod slidably connected thereon are aligned with the mounting plate of the shear pump. Then, the sliding rod is pressed down so that the locking rod and hook rod at one end pass through the through groove on the mounting plate. Then, the hook rod is twisted 90 degrees and pulled upward so that one end of the hook rod is engaged with the locking groove. Finally, the fixing screw is twisted so that it rotates around the rotating frame as the fulcrum and the insert passes through the upper end of the fixed part and engages with the sliding rod through the insertion port. This facilitates the disassembly and maintenance of the shear pump and improves the practicality of the device.

A connecting rod is fixedly connected to one side of the outer wall of the knob. A retaining ring is fixedly connected to one end of the connecting rod. A placeholder bolt is threaded to one end of each end face of the connecting part. A stop block is rotatably connected to one end of each end face of the connecting part. An insertion interface is provided at one end of the outer wall of the insertion interface. A pin is slidably connected to one end of the pin. A fixing rod is fixedly connected to one end of the pin. A high-speed dispersion paddle is fixedly connected to the other end of the fixing rod. Through the above technical solution, the device aligns and slides the pin at one end of the fixed rod into the connector of the servo motor output end. Then, the knob is turned to rotate the connecting rod and the retaining ring at one end of the connecting rod by a certain angle until one end of the retaining ring passes through the connector and forms a locking connection with the pin. Then, the positioning bolt is turned, and the stop block at one end of the positioning bolt slides to the side of the connecting rod after locking under the limit of the end face of the connecting part, preventing the retaining ring from reversing, thus avoiding the loosening of the pin. This facilitates the disassembly and maintenance of the high-speed dispersion paddle and improves the practicality of the device.

[0008] Furthermore, a receiving plate is fixedly connected to the middle of the outer wall of the support frame, and a shearing pump is provided at one end of the upper surface of the receiving plate; Through the above technical solution, the receiving plate is used to set up components such as the shear pump and allows one end of the shear pump to deliver the dispersed colloid.

The ultrasonic transducer facilitates the vibration and dispersion of conductive particles in the colloidal material from a microscopic perspective.

[0010] Furthermore, a can lid is provided at the upper end of the can body, and a servo motor is provided in the middle of the upper surface of the can lid; Through the above technical solution, the can lid serves to seal the can body, and the servo motor serves to power and drive the high-speed dispersing paddle.

[0011] Furthermore, one end of the insert penetrates the middle of the upper end face of the fixing part and forms a locking connection with the middle of the sliding rod, and one end of the hook rod forms a locking connection with the slot; Through the above technical solution, the insert can fix the sliding rod with the fixed part as the fixed point, so that the fixed rod connected to the mounting plate can be indirectly fixed to the output end of the servo motor. The fixed hook rod and the slot can be engaged so that the output end of the servo motor can be quickly fixed together with the high-speed dispersion paddle.

[0012] Furthermore, one end of the retaining ring passes through the middle of one end face of the insertion interface and forms a locking connection with one end of one end face of the pin. The above technical solution enables one end of the pin to be precisely positioned at the depth of the insertion interface and to engage with the retaining ring.

[0013] Furthermore, one end of the stop block is slidably connected to one end of one side face of the connecting part; Through the above technical solution, the sliding of the stop block is more stable, and one end of the connecting part can enhance the stability of the connecting rod at one end of the stop block blocking the retaining ring.
