Description

Technical Field

[0001] The invention relates to the technical field of solder powder processing and feeding, in particular to a remelting feeding mechanism for tin-based alloy spherical solder powder raw materials. Background Art

[0002] Tin-based alloy spherical solder powder material is an indispensable connection material in the electronics industry. The application of surface assembly technology with solder paste as the main connection material makes the electronic assembly process efficient and miniaturized, and has become the mainstream of electronic assembly technology. Solder paste is mainly composed of solder powder and flux paste. One of the most important quality indicators of solder powder is the particle size distribution of the powder, that is, the particle size distribution specification of its product. The general production process of tin-based alloy spherical solder powder is atomization powder making and screening and sorting. The commonly used operation process is to collect coarse powder and fine powder in a tank, and then transport it to an ordinary furnace for direct heating and smelting. Due to the large surface area of ​​the powder, it has been oxidized during the production process, and there are gaps in the middle of the accumulated powder, which leads to slow heat transfer. The heating of ordinary furnaces is through the heat transfer of the furnace body and the open smelting without inert gas protection. The oxide slag generated during the smelting process is large, and the metal loss is serious, which requires remelting processing;

[0003] However, during the use of the traditional tin-based alloy spherical solder powder raw material remelting feeding mechanism, residual materials and debris are often accumulated in the feeding channel of the feeding mechanism. Currently, it can only rely on regular cleaning operations to maintain operation. These accumulations not only seriously hinder the normal advancement of the feeding mechanism, but also cause frequent leakage during the feeding process, resulting in an unnecessary waste of resources.

[0031] The self-cleaning structure 11 includes a connecting seat 12, a connecting shaft 13 and a cleaning roller 14. The connecting seat 12 is fixedly installed on the back side of the push plate 5, the connecting shaft 13 is rotatably set on the inner side of the connecting seat 12, and the cleaning roller 14 is sleeved on the outer surface of the connecting shaft 13, and the cleaning roller 14 is in contact with the inner surface of the feed box 1.

[0032] In this embodiment, a connecting rod 15 is connected through the top of the connecting seat 12, and the connecting rod 15 is inclined relative to the connecting shaft 13, and a gear 16 is connected to the end of the connecting rod 15. The gear 16 extends into the groove of the feeding box 1, and a rack plate 17 adapted to the gear 16 is fixedly installed in the groove of the feeding box 1.

[0033] During the advancement of the push plate 5, the gear 16 and the rack plate 17 can be driven to engage with each other. The engagement of the gear 16 and the rack plate 17 can provide power for the rotation of the cleaning roller 14. The cleaning roller 14 rotates inside the feeding box 1 to perform synchronous cleaning, which can prevent debris and waste from affecting the advancement of the feeding mechanism.

[0034] In this embodiment, a driving pulley 18 is sleeved on the outer surface of the connecting rod 15 , a driven pulley 19 is sleeved on the outer surface of the connecting shaft 13 , and a transmission belt 20 is connected between the driving pulley 18 and the driven pulley 19 .

[0035] The driving pulley 18 rotates with the connecting rod 15 , and can drive the driven pulley 19 to rotate via the transmission belt 20 , thereby realizing the rotation of the connecting shaft 13 connected to the cleaning roller 14 , and realizing the driving of the cleaning roller 14 .

[0036] In this embodiment, a limiting frame 21 is fixedly installed on the inner side of the feeding box 1 near the discharge port, and a guide frame 22 is symmetrically arranged at the end of the feeding box 1, and a leak-proof baffle 23 is arranged on the inner side of the guide frame 22.

[0037] The anti-leakage baffle 23 descends along the guide frame 22, and can perform position limiting protection at the discharge port of the feeding mechanism, thereby avoiding leakage during the feeding process.

[0038] In this embodiment, a limiting card seat 24 is fixedly installed on the top of the limiting frame 21, and a snap-fit ​​head 25 is connected to the inside of the limiting card seat 24. The snap-fit ​​head 25 is adapted to the snap-fit ​​part of the leakage-proof baffle 23, and the snap-fit ​​head 25 extends to the outside of the limiting card seat 24. A guide groove 26 is opened inside the guide frame 22, and both sides of the leakage-proof baffle 23 are connected with connecting heads 27 adapted to the guide groove 26.

[0039] When the push plate 5 is pushed to the discharge end of the feed box 1 , the slider 6 of the push plate 5 contacts the snap-fit ​​head 25 , abutting the snap-fit ​​head 25 , and the snap-fit ​​head 25 no longer limits the leak-proof baffle 23 .

[0040] In this embodiment, the buckle head 25 is movably connected to the limiting frame 21 through the limiting clamping seat 24 , and the leakage-proof baffle 23 is movably connected to the guide frame 22 through the connecting head 27 and the guide groove 26 .

[0042] In this embodiment, a mounting seat 28 is fixedly installed at the end of the feed box 1 near the bottom, and a material guide plate 29 is obliquely provided on the outer side of the mounting seat 28. A plurality of material guide grooves 30 are evenly opened on the outer surface of the material guide plate 29.

[0043] The guide plate 29 cooperates with the guide trough 30 to accurately guide the material during the feeding process of the feeding mechanism, and can also isolate and divert the material, thereby improving the accuracy and uniformity of the feeding of the feeding mechanism.

[0044] In this embodiment, the guide plate 29 is fixedly installed with a snap-fitting column 31 , and the end of the mounting seat 28 is provided with a snap-fitting groove 32 adapted to the snap-fitting column 31 . The guide plate 29 is snap-fitted to the mounting seat 28 via the snap-fitting column 31 and the snap-fitting groove 32 .

[0045] The guide plate 29 is engaged with the mounting seat 28 via the engaging column 31 and the engaging groove 32 , so as to fix the guide plate 29 to the discharge end of the feed box 1 .

[0046] In this embodiment, the push plate 5 is slidably connected to the feed box 1 via a slider 6 , and a slope is provided at the bottom of the push plate 5 .

[0047] The push plate 5 slides inside the feed box 1 to push the material, and the inclined surface at the bottom of the push plate 5 can avoid jamming during the pushing process.

[0048] In this embodiment, a locking head is connected between the material receiving hopper 4 and the fixing frame 3, and the material receiving hopper 4 is fixedly connected to the fixing frame 3 through the locking head.

[0049] By fixing the receiving hopper 4 to the fixing frame 3 at different angles through the locking head, the placement angle of the receiving hopper 4 can be changed, making it easier to select a suitable receiving position.

[0050] It should be noted that the present invention is a remelting feeding mechanism for tin-based alloy spherical solder powder raw materials. When in use, the receiving hopper 4 is fixed to the fixing frame 3 at different angles through the locking head, the placement angle of the receiving hopper 4 can be changed, and a suitable receiving position is selected. The solder powder raw materials enter the feeding box 1 through the receiving hopper 4;

[0051] The electric telescopic rod 10 is started, and the electric telescopic rod 10 pushes the connecting frame 9 to provide power for the push plate 5 to move. The push plate 5 slides inside the feed box 1 to push the material, and the guide rod 8 guides the push plate 5 to push.

[0052] During the advancement of the push plate 5, the gear 16 and the rack plate 17 can be driven to mesh with each other. The gear 16 and the rack plate 17 mesh with each other to provide power for the rotation of the connecting rod 15. The active pulley 18 rotates with the connecting rod 15, and the driven pulley 19 can be driven by the transmission belt 20 to rotate accordingly, so that the connecting shaft 13 connected to the cleaning roller 14 can be rotated, and the cleaning roller 14 can be driven. The cleaning roller 14 rotates to perform synchronous cleaning inside the feeding box 1 to prevent debris and waste from affecting the advancement of the feeding mechanism;

[0053] When the push plate 5 is pushed to the discharge end of the feeding box 1, the slider 6 of the push plate 5 contacts the snap-fit ​​head 25, abuts the snap-fit ​​head 25, and the snap-fit ​​head 25 no longer limits the leakage-proof baffle 23. The snap-fit ​​head 25 moves relative to the limit frame 21 through the limit clamping seat 24, and the snap-fit ​​head 25 is separated from the leakage-proof baffle 23. The leakage-proof baffle 23 moves relative to the guide frame 22 through the connecting head 27 and the guide groove 26. The leakage-proof baffle 23 descends along the guide frame 22 to achieve accurate positioning of the leakage-proof baffle 23, and limit protection is performed at the discharge port of the feeding mechanism to avoid leakage during the feeding process.

[0054] The guide plate 29 is engaged with the mounting seat 28 through the engaging column 31 and the engaging groove 32. After the pushing plate 5 pushes the material out of the feeding box 1, the material falls onto the guide plate 29. The guide plate 29 cooperates with the guide groove 30 to accurately guide the material during the feeding process of the feeding mechanism, and at the same time, the material can be isolated and diverted to complete the remelting feeding of the welding powder raw material.

[0055] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
