Description

Technical Field

[0001] This utility model belongs to the field of packaging production technology and relates to an electronic paste packaging production device. Background Technology

[0002] Electronic paste is an important functional material used in the manufacture of many electronic components such as thick-film integrated circuits, resistors, capacitors, sensors, and solar cells. Its performance and quality directly affect the performance, reliability, and stability of these electronic components. The viscosity of the electronic paste is 20. 500 kPa, viscous in physical state with poor flowability. The product is characterized by small batches and multiple varieties.

[0003] In the production process, vacuum sieving and precise filling are two indispensable steps that heavily rely on manual operation. Vacuum sieving primarily removes air bubbles and tiny particulate impurities from the slurry, ensuring product consistency and reliability. Precise filling involves filling the slurry into specific containers according to a prescribed weight or volume. Currently, this is done manually: operators need to manually place the slurry buckets under the sieving equipment for sieving, and then transfer them to the filling equipment for weighing or metering and filling.

[0004] Some electronic paste formulations contain lead, cadmium, or other heavy metals, organic solvents, and other components that are clearly toxic to human health. Operators frequently handle, move, and transfer high-viscosity pastes, inevitably facing risks of skin contact, inhalation of dust or volatile substances, increasing the workload and risk of worker toxicity.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings:

[0025] Example 1

[0026] This utility model provides an electronic paste packaging production device, including a storage bin 2. The lower end of the storage bin 2 is provided with an extrusion trough 11 that is interconnected with each other. The inlet end of the extrusion trough 11 is provided with a screw. One end of the screw is connected to a power source 7, and the other end is fixedly connected to an extrusion piston 10. The outlet end is provided with a first flange 6. The first flange 6 is provided with a discharge port 12 on the side near the storage bin 2. The electronic paste is stored in a packaging tank 16 through the discharge port 12. The packaging tank 16 is located on the upper end of a weighing assembly 14.

[0027] Specifically, such as Figure 1As shown, the storage silo 2 includes an upper storage silo 21 and a lower storage silo 22. The upper storage silo 21 is equipped with a top cover 1 to prevent material spillage during feeding and to prevent environmental pollution. A second flange 5 is located at the lower end of the upper storage silo 21, and a second flange 5 is also located at the upper end of the lower storage silo 22. A screen support frame 4 is installed between the upper and lower storage silos 21 and 22, and they are sealed together by the second flange 5. Sealing elements are fitted at both ends of the screen support frame 4. The lower end of the lower storage silo 22 is connected to the extrusion trough 11.

[0028] A vacuum buffer pipe is installed on the side of the storage silo 2 away from the first flange 6. The vacuum buffer pipe is used to prevent the electronic paste from overflowing. A solenoid valve 9 is installed at the front end of the vacuum buffer pipe. The opening time and degree of opening of the solenoid valve 9 are controlled by a PC. When adding electronic paste, the electronic paste is first put into the storage silo 2, and then the top cover 1 is closed. Next, the extrusion piston is retracted to the inlet of the extrusion tank 11. At this time, the vacuum is turned on, and a negative pressure is formed in the storage silo 2. Under the action of the negative pressure, the electronic paste enters the extrusion tank through the screen support frame 4. The vacuum screening process can be automatically controlled by the PC program or manually operated. This flexible control method allows the device to adapt to electronic pastes of different viscosities. In particular, high-viscosity electronic pastes can pass smoothly through the screen support frame 4 and enter the extrusion tank 11.

[0029] The inlet end of the extrusion trough 11 is provided with a third flange 8. The two third flanges 8 are detachably connected to the extrusion trough 11. This detachable design facilitates cleaning and maintenance of the inside of the extrusion trough 11. The screw is installed inside the third flange, with one end connected to the power source 7 and the other end fixedly connected to the extrusion piston 10. In this embodiment, the power source 7 is a piston stepper motor. Through the precise control of the piston stepper motor, the screw can move back and forth in the extrusion trough 11, thereby driving the extrusion piston 10 to achieve precise reciprocating motion.

[0030] A sealing element is fitted onto the extrusion piston 10. During the extrusion process of the electronic paste, the sealing element can effectively reduce the residue of paste between the extrusion piston 10 and the inner wall of the extrusion tank 11, improve the utilization rate of the electronic paste, and at the same time prevent the residual paste from drying and causing contamination to the next packaging, thus ensuring packaging quality. After the electronic paste enters the extrusion tank 11 through vacuum sieving and reaches a basically full state, the vacuum system is turned off and the power source 7 is started. The power source 7 drives the extrusion piston forward through the screw, extruding the electronic paste to the discharge port.

[0031] The discharge port 12 is located at the outlet end of the extrusion trough 11, and a first flange 6 is provided at the end away from the storage silo 2. The first flange 6 is tightly connected by bolts. This flange connection method can effectively prevent the material in the storage silo from leaking out from the connection during the discharge process, avoiding material waste, and also preventing the leaked electronic paste from polluting the surrounding environment.

[0032] A dust cover 13 is provided on the side wall of the discharge port 12 and is fixedly connected to the extrusion trough 11. This effectively prevents dust and other impurities from entering the discharge port, ensuring the purity of the electronic paste. The discharge port 12 can use a one-way outlet nozzle or a soft silicone self-sealing nozzle. The one-way outlet nozzle ensures that the electronic paste can only flow out in one direction, preventing external air or impurities from flowing back into the device. The soft silicone self-sealing nozzle has the function of vacuum sealing inward and extruding material outward. It can maintain good sealing performance during vacuum operation and smoothly extrude electronic paste during discharge, further improving the sealing performance and discharge effect of the device.

[0033] A packaging tank 16 is installed at the lower end of the discharge port 12, and the weight of the packaging tank 16 is adjusted by the power source 7. The packaging tank 16 is placed on top of the weighing assembly 14. The weighing assembly 14 can monitor the weight of the electronic paste in the packaging tank 16 in real time and feed the weight signal back to the power source 7. The power source 7 adjusts its output force according to the control signal provided by the weighing assembly 14, thereby controlling the pushing speed and force of the extrusion piston 10, realizing the quantitative filling of the electronic paste into the packaging tank, ensuring that the weight of the electronic paste in each packaging tank 16 is accurate and consistent, and meeting production standards.

[0034] During the forward movement of the extrusion piston 10, it can be controlled manually or automatically. Manual control is suitable for special situations or debugging phases, allowing operators to flexibly adjust the movement of the extrusion piston 10 according to actual conditions. Automatic control, on the other hand, uses a PC to precisely control the entire packaging process, improving production efficiency and the stability of packaging quality.

[0035] A method of using an electronic paste packaging production device:

[0036] The opening time and degree of solenoid valve 9 are set via PC, while the speed of power source 7 and extrusion piston 10 is controlled. These parameters are optimized and adjusted according to the characteristics of the electronic paste (such as viscosity and density) and packaging requirements. The electronic paste is added to storage hopper 2, and the top cover is closed to ensure hopper 2 is sealed. Extrusion piston 10 is retracted to the inlet. The solenoid valve 9 is opened via PC to create a vacuum, forming a negative pressure inside storage hopper 2. Under this negative pressure, the electronic paste passes through screen support frame 4 and enters extrusion tank 10. Once the electronic paste is nearly full, the vacuum system is shut off. During this process, PC program control or manual operation can be selected according to the actual situation.

[0037] Power source 7 is activated, and its screw drives the extrusion piston 10 forward, extruding the electronic paste into the outlet 12 and loading it into the packaging tank 16 below. The weighing component 14 monitors the weight of the electronic paste in the packaging tank 16 in real time and sends the signal back to power source 7. Power source 7 adjusts its output according to the feedback signal to achieve quantitative packaging.

[0038] After all operations are completed, the device can be completely disassembled by removing the first flange 6, the second flange 5, and the third flange 8, and each component can be thoroughly cleaned to ensure that there is no residual electronic paste inside the device.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
