Description

Technical Field

[0001] The invention relates to the technical field of melt tin blowing, in particular to a fuse melt tin blowing device and a process thereof. Background Art

[0002] The fuse's melt undergoes a tin-blowing treatment, specifically applying tin to the melt's surface or specific locations through a specific process. The core purpose of this treatment is to optimize the melt's fusing characteristics. Tin has a melting point far lower than traditional melt materials like copper and lead. When an overload or short-circuit current flows through the melt, the tin melts before the main metal and forms a low-melting-point alloy with the main metal, causing the melt to fuse quickly at a lower temperature.

[0003] In the current enterprise context, the melt tin blowing process is generally operated by manual handheld hot air guns. This method has the problem of low efficiency, and the manual control of the hot air gun distance and position is not fixed, resulting in poor consistency in the quality of the finished product. Summary of the Invention

When the outer rotating sleeve 806 rotates, the blade structure 807 can drive the airflow, thereby increasing the internal air pressure of the arc-shaped bottom cover 803, and then increasing the jet pressure of the upper blowing hole 805.

[0035] A rotating sleeve gear ring 808 is fixed on the outside of the outer rotating sleeve 806, and an intermediate gear 809 is meshed on the outside of the rotating sleeve gear ring 808.

An anti-blocking disk 815 is fixed at the upper center position of the intermediate gear 809, and a hollow rotating shaft 816 is fixed at the lower center position of the intermediate gear 809. The upper end of the hollow rotating shaft 816 is connected to the center position of the upper surface of the intermediate gear 809; a tin liquid flow channel 817 is opened in the stabilizing cross-tube 8, and one end of the tin liquid flow channel 817 is rotatably connected to the hollow rotating shaft 816.

[0037] A tin liquid storage bin 818 is provided in the stabilizing cross-tube 8. The other end of the tin liquid flow channel 817 is connected to the tin liquid storage bin 818. An openable and closable cleaning bin cover 819 is provided above the tin liquid storage bin 818. A cylindrical side cavity 820 is provided on one side of the tin liquid storage bin 818. A filter membrane window 821 is provided between the tin liquid storage bin 818 and the cylindrical side cavity 820. Gas can be filtered through the filter membrane window 821, so that only gas in the tin liquid storage bin 818 can enter the cylindrical side cavity 820. A piston component 822 is provided in the cylindrical side cavity 820 , and a tension spring component 823 is provided on the side of the piston component 822 away from the filter membrane window 821 . The tension spring component 823 provides elastic tension, so that the piston component 822 has an elastic tendency to move away from the filter membrane window 821 .

[0038] The cylindrical side cavity 820 is connected to the outside with a one-way exhaust valve 824, which allows the gas in the cylindrical side cavity 820 to flow in one direction toward the outside atmosphere. The end of the cylindrical side cavity 820 is connected to a quick exhaust groove 825, and a lifting gate 826 is provided below the quick exhaust groove 825. When the lifting gate 826 moves upward, it can close the quick exhaust groove 825. A gate spring 827 is provided above the lifting gate 826, and the gate spring 827 applies downward elastic pressure to the lifting gate 826. The end of the cylindrical side cavity 820 is also provided with an air inlet side hole 828 and an air supply duct 829. The air supply duct 829 can drive the lifting gate 826 to move upward to close the quick exhaust groove 825 by inputting positive pressure gas. At this time, the air supply duct 829 is connected to the air inlet side hole 828, and the gas enters the cylindrical side cavity 820 through the air inlet side hole 828; an air pump assembly 830 is provided in the stabilizing cross-tube 8, and a cam portion 831 is fixedly provided on the power shaft 812. When the power shaft 812 rotates, the cam portion 831 is driven to rotate, and the cam portion 831 cooperates with the air pump assembly 830 to generate positive pressure gas, and inputs it into the air supply duct 829; the air pump assembly 830 is a press-driven piston pump structure, and the intermittent squeezing of the air pump assembly 830 by the cam portion 831 during the rotation process causes the air pump assembly 830 to operate.

[0039] A processing technology for fuse melt tin blowing equipment, which uses the fuse melt tin blowing equipment and includes the following steps: Step 1: Evenly arrange the fuse melt on the carrier plate 3 and fix the two ends with tape; Step 2: Apply solder paste to the corresponding position of the fuse element; Step 3: Position the carrier plate 3 on the positioning fixture 7; Step 4: The hot air gun 5 is running, and the slide assembly 2 drives the fuse melt on the carrier plate 3 through the positioning fixture 7 to pass through the hot air gun 5 in sequence to complete the tin blowing process.

[0040] like Figure 3 and Figure 4 As shown in the figure, the hot air gun 5 and the upper blowing hole 805 correspond to each other up and down. When the fuse melt moves to the top of the upper blowing hole 805 under the drive of the carrier plate 3, it is just below the hot air gun 5. At this time, the hot air gun 5 sprays high-temperature air to melt the solder paste. However, since the upper blowing hole 805 is blocked by the fuse melt, the high-temperature air flow sprayed by the hot air gun 5 will not be directly sprayed into the upper blowing hole 805. The high-temperature air flow sprayed by the hot air gun 5 passes through the fuse melt and is diverted and diffused into the arc-shaped air guide groove 801. Figure 5 As shown in the figure, the air guide structure formed by the arc-shaped air guide groove 801 and the arc-shaped bottom cover 803 allows the air flow to enter the interior of the arc-shaped bottom cover 803 through the air inlet hole 804, and then be ejected upward through the upper blowing hole 805, and the jet is heated from the bottom of the fuse melt, thereby reducing the problem of uneven distribution of the tin liquid. If the above structure is not set, the solder paste on the fuse melt is heated and melted by the vertical downward jet of the hot air gun 5. Under the influence of the air flow and the gravity of the molten tin liquid, more of the tin liquid is gathered below the fuse melt, resulting in uneven distribution of the tin liquid above and below the corresponding parts of the fuse melt. However, through the above structure, the corresponding upward jet heating is carried out below the fuse melt, which can make the tin liquid more evenly distributed.

[0041] The following structure is used to adjust and strengthen the air pressure of the upper blowing hole 805 to improve the uniformity of the effect, such as Figure 5 As shown in FIG, the power shaft 812 is driven to rotate by the motor component 813, and ... Figure 6 As shown in FIG, the driving pinion 811 drives the intermediate gear 809 to rotate at high speed, and the intermediate gear 809 drives the rotating sleeve gear ring 808 to rotate by meshing ... Figure 9When the rotating sleeve gear ring 808 rotates at high speed, the outer rotating sleeve 806 and the blade structure 807 rotate synchronously, creating an airflow drive effect inside the air inlet hole 804. The air below the air inlet hole 804 is actively drawn into the curved bottom cover 803, increasing the pressure inside the curved bottom cover 803 and, in turn, the pressure of the jet from the upper blow hole 805. Furthermore, there is no need to install components such as a motor inside the curved bottom cover 803, making the interior of the curved bottom cover 803 more resistant to high temperatures, thereby adapting to the temperature of the hot air gun 5.

[0042] like Figure 6 As shown in , in actual operation, there is a risk that the tin liquid will drip into the interior of the arc-shaped bottom cover 803 through the upper blowing hole 805. The tin liquid can be temporarily stored by the centrifugal storage eaves 814, and because the intermediate gear 809 and the centrifugal storage eaves 814 are synchronously in a high-speed rotation state during operation, the centrifugal force can be used to make the tin liquid stick to the inner wall of the centrifugal storage eaves 814 and not flow into the hollow shaft 816. Since the inside and outside of the centrifugal storage eaves 814 are heated by the high-temperature gas ejected by the hot air gun 5, the tin liquid can be kept in a molten liquid state. The anti-blocking shielding disc 815 is set so that the tin liquid will not directly enter the hollow shaft 816 when dripping. Since the inside of the hollow shaft 816 and the tin liquid flow channel 817 are far away from the hot air of the hot air gun 5, the temperature is slightly lower, which can easily cause the tin liquid to solidify and clog.

[0043] After the tin blowing operation is completed and the equipment is shut down, the centrifugal storage eaves 814 stops rotating. After losing the centrifugal force, the tin liquid flows to the upper end of the hollow rotating shaft 816. The tin liquid flow channel 817 will immediately generate negative pressure suction to extract the tin liquid in the centrifugal storage eaves 814 into the tin liquid storage bin 818.

[0044] For the negative pressure control of the tin liquid flow channel 817, as shown in FIG. Figure 5 As shown in FIG, during the operation of the device, the power shaft 812 rotates, driving the cam portion 831 to rotate, and the cam portion 831 cooperates with the air pump assembly 830 to generate positive pressure gas, which is input into the air supply channel 829. Figure 7 As shown in , the positive pressure gas in the air supply duct 829 first drives the lifting gate 826 to move upward, so that the lifting gate 826 closes the quick exhaust groove 825. When the lower part of the lifting gate 826 is higher than the position of the air inlet side hole 828, the positive pressure gas in the air supply duct 829 enters the cylindrical side cavity 820 through the air inlet side hole 828, driving the piston component 822 to move right. At this time, the tension spring component 823 is stretched and stores force.

[0045] See Figure 5As shown in , as the piston component 822 moves to the right, after the piston component 822 passes through the one-way exhaust valve 824, the gas in the cylindrical side chamber 820 is discharged to the outside atmosphere through the one-way exhaust valve 824. At this time, the piston component 822 always remains on the right side of the one-way exhaust valve 824. When the equipment is shut down, the power shaft 812 stops rotating, the positive pressure gas in the air supply channel 829 is lost, and the lifting gate 826 moves downward and resets under the elastic pressure of the gate spring 827, so that the quick exhaust groove 825 is opened. At this time, the gas on the left side of the piston component 822 is quickly discharged to the outside atmosphere through the quick exhaust groove 825. Under the elastic tension of the tension spring component 823, the piston component 822 moves rapidly to the left, so that the right side of the piston component 822 is in a negative pressure state.

[0046] Due to the one-way permeability of the one-way exhaust valve 824, external gas will not enter the cylindrical side cavity 820 through the one-way exhaust valve 824. The negative pressure passes through the filter membrane window 821 and the tin liquid storage tank 818, causing the tin liquid flow channel 817 to evacuate air and draw the tin liquid into the tin liquid storage tank 818. The tin liquid gradually solidifies in the tin liquid storage tank 818. The cleaning tank cover 819 can be opened for unified cleaning and maintenance.
