The spherical solder powder developed by EXCT is mainly available in grades 3 and 4. First, they are sieved with a vibrating separator. However, there are some problems in the design process: First, the spherical tin solder easily bridges the holes in the grid. It is not easy to clean, resulting in poor dust resistance; long wet sieving time will increase the oxygen content of the spherical tin powder, resulting in too high oxygen content of the tin powder; third, the screen is often broken, and the screen is time-consuming and labor-intensive. These problems have seriously affected the production efficiency of tin powder, causing most of the recycled tin powder to be easily oxidized into slag during the remelting process, which reduces the performance of the vibrating separator. It is mainly suitable for the classification of spherical flux (3a, welding). The screen is usually divided into two layers: the upper layer is 325 mesh, and the lower layer is 500 mesh. The product is 325-500 mesh powder. The screening machine does not work properly when it is first started. The main problem is that the filter is easily damaged, clogged, difficult to clean, and poor detection efficiency. Discuss the above-mentioned problems, characteristics, and reasons for the vibrating separator. The main reason is: the mesh is not tight enough or the tension is uneven. The vibration motor rotates abnormally. The accumulation of material contains a large number of particles near the separation point. The material is composed of spherical particles. Generate static electricity or agglomeration and calibrate the network. Set the phase angle of the weight. There are not enough vacancies. Improvement 1 Change the screen bonding process. Place the screen on the screen. Use the ring to fix the screen to the screen, and use the ring adjustment screw to adjust the tension of the screen fabric. Apply glue to the edges of the net and fasten the net firmly to the net. Remove the excess filter from around the filter. 2 Change the cleaning method of the grid. Drill holes in the screen and clean the screen. However, during use, the holes on the screen are particularly large, indicating that the effect of this circuit is not obvious, the height and strength of the rebound are difficult to control, and the screen is easily damaged. The ultrasonic vibration cleaning ball is composed of an ultrasonic generator, an ultrasonic transducer, and a vibration separator for effective cleaning and screening.3 Adjust the inclination angle of the material block By adjusting the phase angle of the material block, the trajectory and residence time of the material on the screen can be changed: if the phase angle is less than 15°, the powder residence time will be shorter. The time is short, which is only suitable for basic inspection; when the angle is 45°, the powder stays on the screen surface of the vibrating separator for a long time, which is suitable for fine screening. If the phase angle is greater than 45°, the powder channel is close to the center for special purposes. The screen performance is also guaranteed so that the time for dust removal from the screen surface will not be too long or too short. Tests have shown that the phase of the entire mass is between 15 and 45 degrees, depending on the intensity of the vibration. Layer separation Use effect and economic benefits With the improvement of the screen tensioning process, cleaning process and intelligent adaptation of the charging stage, the status quo of frequent damage of fabric vibration has been completely changed. The screen lock speed has been significantly reduced. Effectively extend the screen life. Taking 3a spherical tin powder as an example, the average service life of each sieve (325 mesh) can be increased by 10-20 times, the efficiency of the powder sieve can be increased by 20%, and the economic benefits can be significantly improved.
