Description

Technical Field

[0001] The present application relates to the technical field of nano copper powder, and more specifically, to a filtering and collecting device for preparing nano copper powder based on electronic slurry. Background Art

[0002] Electronic paste is the basic material for manufacturing thick film components. It is a paste that is evenly mixed by three-roll rolling of solid powder and organic solvent. According to different uses, electronic paste is divided into dielectric paste, resistor paste and conductor paste. According to the price of the conductive phase, it is divided into precious metal electronic paste (silver palladium, ruthenium and gold paste, etc.) and base metal electronic paste (copper molybdenum manganese paste). Electronic paste is widely used in various fields of the electronics industry. With the rise in international silver prices, the cost of silver paste increases, so people consider using non-precious metal paste. Copper is an ideal raw material for making electronic paste. It is much cheaper than silver and is a cost-effective raw material.

[0003] A convenient nano-copper powder collecting device disclosed by searching the publication number CN214862564U includes a cover plate, an air pipe, an outer box, a drain pipe, a filter membrane, a switch door, an opening and a feeding mechanism. The utility model arranges the feeding mechanism on the inner side of the outer box, and performs buffering treatment on the introduced nano-copper solution through the buffer plate, thereby reducing the speed of the nano-copper solution entering the outer box. In addition, since the through holes are arranged obliquely, it is convenient to disperse the nano-copper solution on the inner side of the guide frame and introduce it to the top of the filter membrane, thereby achieving the beneficial effect of introducing the nano-copper solution to the top of the filter membrane in a slow and diffuse manner, reducing the impact force on the filter membrane, and improving the service life of the filter membrane.

[0004] However, this application has certain shortcomings. The guide frame moves left and right to filter the nano-copper solution, and the guide frame is easily blocked gradually, resulting in poor subsequent effects and slow filtration of the nano-copper solution. There is a lack of function to clean the blocked guide frame in time, which is not conducive to the use of the device. In addition, the cover plate is set at the top, and the sliding direction of the guide frame is horizontal. It is inconvenient to slide it out of the sliding frame and move it up to the cover plate to take it out.

[0005] In order to solve the above problems, the present application provides a filtering and collecting device for preparing nano copper powder based on electronic slurry. Summary of the invention

[0006] The present application provides a filtering and collecting device for preparing nano copper powder based on electronic slurry, which adopts the following technical solution:

[0007] A filtering and collecting device for preparing nano copper powder based on electronic slurry comprises an outer box, a sliding rod is fixedly connected between the inner walls of the outer box, a sliding frame is arranged inside the outer box, the sliding frame is slidably matched with the sliding rod, a guide frame is arranged inside the sliding frame, and a plurality of through holes are opened on the bottom surface of the guide frame, a traction mechanism is connected to the side of the sliding frame, a sliding rail is arranged inside the sliding frame, and the guide frame is slidably matched with the sliding rail, a plurality of springs are fixedly connected to the top surface of the sliding frame, and an elastic plate is fixedly connected to the bottom surface of the spring, the elastic plate abuts against the guide frame, a striking block is arranged on the bottom surface of the guide frame, and the striking block is connected to a driving mechanism, and the striking block is an elliptical block structure.

[0008] Through the above technical scheme, the guide frame can be struck by the striking block, which is driven to rotate by the driving mechanism and hits the bottom of the guide frame. The guide frame rises and is rebounded by the elastic plate. The blockage on the guide frame can be cleaned to avoid the subsequent deterioration of the filtering effect, which is beneficial to the use of the device.

[0009] Furthermore, the driving mechanism includes a motor and a rotating shaft. The center of the striking block is provided with a rotating shaft, and the rotating shaft is fixedly connected to the output end of the motor. The motor is connected to a telescopic mechanism.

[0010] Through the above technical solution, the motor drives the rotating shaft to rotate, thereby driving the striking block to rotate. The striking block is an elliptical block. During the rotation process, it can hit the bottom of the guide frame, thereby shaking up the blocked nano-copper particles to prevent their stacking and causing the filtering effect to deteriorate.

[0011] Furthermore, the telescopic mechanism includes a cylinder and a shell, the rear end face of the outer box is fixedly mounted with the cylinder, and the output end of the cylinder passes through the inner wall of the outer box, extends to the inner cavity and is fixedly connected to the shell, and the motor is installed inside the shell.

[0012] Through the above technical solution, the cylinder can drive the shell and the motor to extend and retract. When filtering is required, the shell and the motor are away from the guide frame, and when cleaning is required, the shell is sent to the bottom of the guide frame.

[0013] Furthermore, a flow block is fixedly connected to the top surface of the shell, and the flow block is a triangular block structure.

[0014] Through the above technical solution, the triangular block structure of the flow block can make the nano copper solution flow down smoothly and avoid it from stagnating on the shell.

[0015] Furthermore, a heat sink is fixedly connected to the bottom surface of the shell, and the heat sink fins of the heat sink are vertically downward.

[0016] Through the above technical solution, the heat dissipation plate can dissipate heat from the housing, thereby dissipating heat from the motor, thereby increasing the service life of the motor.

[0017] Furthermore, two limit blocks are fixedly connected to the top surfaces on both sides of the guide frame, and the limit blocks are engaged with the elastic plates.

[0018] Through the above technical solution, the elastic plate can be limited and fixed by the limiting block, so that the elastic plate always contacts the guide frame.

[0019] Furthermore, a through groove is provided on the side of the outer box away from the cylinder, and a mounting door is installed in the through groove, and a rubber ring is provided on the inner side of the mounting door.

[0020] Through the above technical solution, the guide frame can be easily taken out by installing the door.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] The guide frame can be struck by the striking block, which is driven to rotate by the driving mechanism and hits the bottom of the guide frame. The guide frame rises and is rebounded by the elastic plate, which can clean the blockage on the guide frame and avoid the subsequent deterioration of the filtering effect, which is beneficial to the use of the device.
