Description

Technical Field

[0001] This invention relates to the field of copper powder recycling technology for waste circuit boards, and in particular to a classification, conveying and collection device and method for recycling copper powder from waste circuit boards. Background Technology

[0002] Copper powder recycling from waste circuit boards is a crucial step in resource recycling because circuit boards contain a significant amount of precious metals and valuable raw materials, especially copper. Waste circuit boards (WEEE) typically contain metals such as gold, silver, copper, lead, and tin, which, when properly processed, can be recycled and reused, reducing environmental pollution and dependence on natural resources. Copper recycling is particularly important because it is widely used in the connections and conductive components of electronic devices.

[0003] With the rapid development of new energy vehicles, the widespread adoption of electric vehicles (EVs) has led to a surge in demand for batteries, electronic components, and circuit boards. These EVs utilize a large number of electronic components and circuit boards in their charging infrastructure, battery management systems, and electric drive systems, and these components typically contain high concentrations of metals such as copper, lithium, and cobalt. Therefore, the recycling of copper from waste circuit boards is not only crucial for the recycling of traditional electronic equipment but also plays an increasingly important role in the new energy vehicle industry.

[0004] The prior art publication CN109865735B provides a waste circuit board recycling device that is applicable to waste circuit boards of different sizes and has a wide range of applications. It obtains finer and more uniform circuit board particles through coarse crushing and three-stage grinding, and then collects them by sorting. It has a high recycling rate, is more environmentally friendly and efficient, and can recycle waste circuit boards industrially.

[0005] Existing technologies enable the crushing and recycling of waste circuit boards. However, when recycling copper powder from these boards, existing technologies struggle to automatically sort the solder residue. Solder, typically composed of tin, lead, and other metallic elements, can reduce the purity of the copper powder, impacting its recycling quality and reuse value. The inclusion of solder impurities also destabilizes the quality of the recovered copper powder, affecting subsequent smelting and reuse processes.

[0006] In summary, the existing technology lacks a technique for sorting and pre-treating solder on waste circuit boards. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of the prior art by proposing a sorting, conveying, and collecting device and method for recycling copper powder from waste circuit boards.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a sorting, conveying, and collecting device for recycling copper powder from waste circuit boards, comprising a conveying frame, a fixed seat fixedly connected to the conveying frame, a rotating seat rotatably connected inside the fixed seat, a plurality of solder separation mechanisms rotatably connected through the rotating seat, a filter cover rotatably connected to the lower side of the solder separation mechanism, a plurality of transmission mechanisms fixedly connected to the outer side of the rotating seat, a transmission ring rotatably connected to the inner wall of the fixed seat, the transmission ring being driven by the transmission mechanism, the transmission mechanism being driven by the solder separation mechanism, and a solder heating tube being fixedly connected through the top of the fixed seat.

[0009] Preferably, two pulleys are rotatably connected to the conveyor frame, and a conveyor belt is provided between the two pulleys for frictional transmission. One end of one pulley extends through the inner wall of the conveyor frame to the outside and is fixedly connected to a universal joint assembly. The universal joint assembly is rotatably connected to the conveyor frame, and a drive wheel is fixedly connected to the other end of the universal joint assembly. A bevel gear ring is fixedly connected to the outer end of the transmission ring, and an annular rack is fixedly connected to the inner side of the transmission ring. The drive wheel meshes with the bevel gear ring for transmission.

[0010] Preferably, the upper inner wall of the fixed seat is provided with a guide groove, one side of the guide groove is recessed, the transmission mechanism includes a guide shaft, the guide shaft is slidably engaged with the inner wall of the guide groove, the bottom side of the fixed seat is provided with an opening, and a receiving seat is fixedly connected to the inner wall of the bottom of the fixed seat.

[0011] Preferably, a rotating shaft is fixedly connected to the bottom end of the rotating seat, the other end of the rotating shaft is rotatably connected to the inner wall of the fixed seat, and a motor is fixedly connected to the outer end of the rotating shaft, and the motor is fixedly connected to the fixed seat.

[0012] Preferably, the solder separation mechanism includes a rotating tube with a tapered inner wall. The rotating tube is rotatably connected to a rotating seat. A separation tube is fixedly connected to the inner wall of the rotating tube. A movable ring is slidably fitted to the outer wall of the rotating tube. The transmission mechanism includes a pressure roller that slidably contacts the movable ring. Multiple springs are fixedly connected to the bottom end of the movable ring. The other end of each spring is fixedly connected to the rotating tube. One end of the movable ring extends through the outer wall of the rotating tube via a connecting rod and is fixedly connected to an adjusting rack. A gear is fixedly connected to one end of the filter cover. The gear meshes with the adjusting rack for transmission.

[0013] Preferably, the transmission mechanism further includes a fixed block, which is fixedly connected to the outer wall of the rotating seat. A sliding rod is slidably fitted through the fixed block. One end of the sliding rod is rotatably connected to the guide shaft, and one side of the sliding rod is rotatably connected to the pressure roller. A transmission wheel is rotatably connected to the top of the sliding rod. A toothed ring is fixedly connected to the rotating tube. One side of the transmission wheel meshes with the toothed ring for transmission, and the other side of the transmission wheel meshes with a ring rack for transmission.

[0014] Preferably, a fan blade is rotatably connected to the inner wall of the top end of the soldering heating tube, a driven wheel is fixedly connected to the shaft end of the fan blade, a geared disc is meshed and driven on one side of the driven wheel, and the geared disc is rotatably connected to the outer wall of the soldering heating tube.

[0015] Preferably, the bottom end of the gear plate extends through the outer wall of the fixed base into the interior and is fixedly connected to a drive wheel. The drive wheel meshes with the annular rack for transmission. Multiple heating wires are installed and fixedly connected to the inner wall of the soldering heating tube.

[0016] A method for using a sorting, conveying, and collecting device for recycling copper powder from waste circuit boards includes the following steps:

[0017] S1. Before recycling copper powder from waste circuit boards, place the waste circuit boards into the solder separation mechanism and use the rotating seat to move the waste circuit boards to the bottom of the solder heating tube.

[0018] S2. While the conveyor is conveying, the structure inside the solder heating tube can be driven by the transmission ring to inject heated air into the solder separation mechanism to heat and melt the solder.

[0019] S3. At the same time, the transmission ring will drive the solder separation mechanism to rotate through the transmission mechanism, so that the molten solder on the waste circuit board will be separated.

[0020] S4. Then, when the rotating seat moves the waste circuit board to the bottom opening of the fixed seat, the transmission mechanism will automatically open the filter cover, allowing the waste circuit board to fall onto the conveyor frame for the next crushing and recycling process.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By setting up a solder separation mechanism and heating wire, the heating wire can heat the waste circuit board in the separation tube, causing the solder on the waste circuit board to melt. At this time, the rotating separation tube can melt and separate the solder in advance before the waste circuit board is crushed for copper powder recycling. This can prevent lead, tin and other metal impurities in the solder from being mixed into the copper powder, effectively reducing impurities when recycling copper powder, thereby improving recycling efficiency, reducing dependence on subsequent sorting and reducing production costs.

[0023] 2. By setting up a transmission mechanism and transmission ring, the solder separation mechanism can be automatically driven to rotate while the conveyor belt is rotating. At the same time, when the transmission mechanism moves down to release the transmission, it can automatically drive the filter cover to open, so that the waste circuit boards after solder separation can automatically fall onto the conveyor belt. This enables automated material flow after the solder separation of waste circuit boards, which not only further improves recycling efficiency, but also makes the waste circuit board recycling process more environmentally friendly, efficient and economical.

[0024] 3. By setting up a soldering heating tube, the fan blades can be driven to rotate while the transmission ring rotates, continuously blowing the air heated by the heating wire into the soldering separation mechanism. This achieves uniform and efficient heating, energy saving and environmental protection, and improved recycling rate during the soldering melting process of waste circuit boards. It not only optimizes the recycling process and improves overall efficiency, but also reduces the impact on the environment and ensures higher quality resource recycling and processing.

[0036] like Figure 3 , Figure 7As shown, two pulleys 101 are rotatably connected to the conveyor frame 1, and a conveyor belt 102 is driven by friction between the two pulleys 101. One end of one pulley 101 extends through the inner wall of the conveyor frame 1 to the outside and is fixedly connected to a universal joint assembly 103. The universal joint assembly 103 is rotatably connected to the conveyor frame 1, and a drive wheel 104 is fixedly connected to the other end of the universal joint assembly 103. A bevel gear ring 701 is fixedly connected to the outer end of the transmission ring 7, and an annular rack 702 is fixedly connected to the inner side of the transmission ring 7. The drive wheel 104 meshes with the bevel gear ring 701 for transmission. While the pulley 101 drives the conveyor belt 102 to rotate, the pulley 101 can drive the drive wheel 104 connected to the universal joint assembly 103 to rotate, so that the drive wheel 104 can drive the transmission ring 7 connected to the bevel gear ring 701 to rotate.

[0037] like Figure 4 As shown, a guide groove 201 is provided on the inner wall of the upper end of the fixed base 2. One side of the guide groove 201 is recessed. The transmission mechanism 6 includes a guide shaft 603, which is slidably engaged with the inner wall of the guide groove 201. An opening is provided on one side of the bottom end of the fixed base 2. A receiving seat 202 is fixedly connected to the inner wall of the bottom end of the fixed base 2.

[0038] like Figure 4 As shown, a rotating shaft 301 is fixedly connected to the bottom of the rotating seat 3.

[0039] like Figure 5 As shown, the solder separation mechanism 4 includes a rotating tube 401 with a tapered inner wall. The rotating tube 401 is rotatably connected to the rotating seat 3.

One end of the movable ring 404 extends through the outer wall of the rotating tube 401 via a connecting rod and is fixedly connected to an adjusting rack 406. A gear 501 is fixedly connected to one end of the filter cover 5. The gear 501 meshes with the adjusting rack 406 for transmission. The transmission ring 7 can drive the transmission wheel 605 to rotate through the ring rack 702. At this time, the transmission wheel 605 will drive the rotating tube 401 connected to the ring 402 to rotate, so that the rotating tube 401 can drive the connected separation tube 403 to rotate.

[0040] By setting up a solder separation mechanism 4 and a heating wire 805, the heating wire 805 can heat the waste circuit board in the separation tube 403, causing the solder on the waste circuit board to melt. At this time, by using the rotating separation tube 403, the solder can be melted and separated in advance before the waste circuit board is crushed for copper powder recycling. This can prevent lead, tin and other metal impurities in the solder from being mixed into the copper powder, effectively reducing impurities during copper powder recycling, thereby improving recycling efficiency, reducing reliance on subsequent sorting and lowering production costs.

[0041] like Figure 6 As shown, the transmission mechanism 6 also includes a fixed block 601, which is fixedly connected to the outer wall of the rotating seat 3. A sliding rod 602 is slidably fitted through the fixed block 601. One end of the sliding rod 602 is rotatably connected to the guide shaft 603, and another side of the sliding rod 602 is rotatably connected to the pressure roller 604. A transmission wheel 605 is rotatably connected to the top of the sliding rod 602. A gear ring 402 is fixedly connected to the rotating tube 401. One side of the transmission wheel 605 meshes with the gear ring 402 for transmission, and the other side of the transmission wheel 605 meshes with the ring rack 702 for transmission. The pressure roller 604 can reduce the friction force when the movable ring 404 rotates.

[0042] like Figure 8 As shown, a fan blade 801 is rotatably connected to the inner wall of the top end of the soldering heating tube 8. A driven wheel 802 is fixedly connected to the shaft end of the fan blade 801. A gear disc 803 is meshed and driven on one side of the driven wheel 802. The gear disc 803 is rotatably connected to the outer wall of the soldering heating tube 8.

[0043] The bottom end of the gear plate 803 extends through the outer wall of the fixed base 2 and is fixedly connected to the drive wheel 804. The drive wheel 804 is meshed with the ring rack 702 for transmission. Multiple heating wires 805 are installed and fixedly connected to the inner wall of the solder heating tube 8.

[0044] A method for using a sorting, conveying, and collecting device for recycling copper powder from waste circuit boards includes the following steps:

[0045] S1. Before recycling copper powder from waste circuit boards, place the waste circuit boards into the solder separation mechanism 4 and use the rotating seat 3 to move the waste circuit boards to the bottom of the solder heating tube 8.

[0046] S2. While the conveyor frame 1 is conveying, the structure inside the solder heating tube 8 can be driven by the transmission ring 7 to inject heated air into the solder separation mechanism 4 to heat and melt the solder.

[0047] S3. At the same time, the transmission ring 7 will drive the solder separation mechanism 4 to rotate through the transmission mechanism 6, so that the molten solder on the waste circuit board will be separated.

[0048] S4. Then, when the rotating seat 3 moves the waste circuit board to the bottom opening of the fixed seat 2, the transmission mechanism 6 will drive the filter cover 5 to open automatically, so that the waste circuit board can fall onto the conveyor frame 1 for the next crushing and recycling process.

[0049] Working principle: Before recycling copper powder from waste circuit boards, the waste circuit boards are placed in the separation tube 403. Then, the motor 302 drives the rotating seat 3 to rotate 90 degrees, at which point the waste circuit boards are rotated to the bottom of the soldering heating tube 8.

[0050] Then, while the pulley 101 drives the conveyor belt 102 to rotate, the pulley 101 can drive the drive wheel 104 connected to the universal joint 103 to rotate, so that the drive wheel 104 can drive the transmission ring 7 connected to the bevel ring 701 to rotate.

[0051] Then, the transmission ring 7 can drive the gear disk 803 connected to the drive wheel 804 to rotate through the ring rack 702, so that the gear disk 803 can drive the fan blade 801 connected to the driven wheel 802 to rotate, thereby injecting the air heated by the heating wire 805 into the separation tube 403 to melt the solder on the waste circuit board.

[0052] At the same time, the rotating transmission ring 7 can drive the transmission wheel 605 to rotate through the ring rack 702. At this time, the transmission wheel 605 will drive the rotating tube 401 connected to the ring 402 to rotate, so that the rotating tube 401 can drive the connected separation tube 403 to rotate, so that the molten solder on the waste circuit board can be separated through the separation tube 403 and fall into the receiving seat 202.

[0053] Then, as the motor 302 continues to drive the rotating seat 3 to rotate, the separated waste circuit board moves to the bottom opening of the fixed seat 2. At this time, the guide shaft 603 will move to the recess of the guide groove 201, which will cause the guide shaft 603 to drive the transmission wheel 605 on the sliding rod 602 to move down. At this time, the transmission wheel 605 does not mesh with the toothed ring 402.

[0054] At the same time, the sliding rod 602 moves downward and applies pressure to the movable ring 404 through the connected pressure roller 604, causing the movable ring 404 to drive the connected adjusting rack 406 to move, so that the adjusting rack 406 can drive the filter cover 5 connected to the gear 501 to rotate and open, so that the waste circuit board can fall onto the conveyor frame 1 for the next crushing and recycling process.
