[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a circuit board copper powder recovery device, including a screening box 1, a safety door 4 installed on the front of the screening box 1, and heat dissipation holes 5 on both the left and right sides of the screening box 1, a feed hopper 2 installed on the top of the screening box 1, a cover plate 3 fixedly installed on the front of the screening box 1 and below the safety door 4, and a vibration device body 6 fixedly installed on the bottom of the inner wall of the screening box 1, a transmission rod 8 movably installed at the output end of the vibration device body 6 and on the inner wall of the screening box 1, four limiting rods 7 fixedly installed on the top of the inner wall of the screening box 1, and three limiting frames 9 slidably connected to the outer walls of the four limiting rods 7, and connecting brackets 10 slidably connected inside the three limiting frames 9, while sleeves 91 are installed at the bottom of the three limiting frames 9 and on the outer walls of the four limiting rods 7, and a precision filter screen 13, a filter screen 12 and a primary filter screen 11 are sequentially installed inside the three connecting brackets 10.

[0023] The feeding hopper 2, cover plate 3, safety door 4, vibrating device body 6, and four limiting rods 7 can be installed in the screening box 1. A transmission rod 8 is movably installed at the output end of the vibrating device body 6, located on the inner wall of the screening box 1. Three limiting frames 9 are slidably connected to the outer walls of the four limiting rods 7. Connecting brackets 10 are slidably connected inside each of the three limiting frames 9. A precision filter screen 13, a filter screen 12, and a primary filter screen 11 are sequentially installed inside each of the three connecting brackets 10, thereby pulverizing the metal conductors of the circuit board. Material can be fed into the inner wall of the screening box 1 through the feed hopper 2 and placed on top of the precision filter screen 13. The collection container is placed on top of the transmission rod 8. At this time, the main body of the vibration device 6 is started, which can drive the transmission rod 8, the three limit frames 9, the three connecting brackets 10, and the precision filter screen 13, filter screen 12 and primary filter screen 11 to shake up and down along the four limit rods 7. This allows the precision filter screen 13, filter screen 12, connecting brackets 10 and the container to separate copper powder and impurities in the circuit board. The separation process is time-saving and labor-saving.

[0024] See Figure 2 , Figure 3 The upper ends of the four limiting rods 7 are fixedly connected to the top of the inner wall of the screening box 1, and the lower ends of the four limiting rods 7 are respectively inserted into the inside of the transmission rod 8. Sleeves 91 are fixedly installed at the four corners of the bottom of the three limiting frames 9, and the sleeves 91 are respectively fixedly connected to the top of the transmission rod 8.

[0025] Four limiting rods 7 can be installed through the screening box 1. Since the lower ends of the four limiting rods 7 are respectively inserted into the inside of the transmission rod 8, the main body 6 of the vibration device is activated, which can drive the transmission rod 8 to move up and down along the limiting rods 7. Since sleeves 91 are fixedly installed at the four corners of the bottom of the three limiting frames 9, and the sleeves 91 are respectively fixedly connected to the top of the transmission rod 8, the upward movement of the transmission rod 8 will drive the sleeves 91 and the three limiting frames 9 to vibrate up and down along the four limiting rods 7 at the same time.

[0026] See Figure 3 , Figure 4 Each of the three limiting frames 9 has a through hole 92 on its inner wall, and the through hole 92 is connected to the sleeve 91. The sleeve 91 and the through hole 92 are slidably connected to the outer wall of the four limiting rods 7. Each of the three limiting frames 9 is C-shaped, and each of the three limiting frames 9 has a slot 93 on its inner wall. Each of the three slots 93 has a slider 94 slidably connected to its inner wall, and each of the three sliders 94 has a connecting bracket 10 slidably connected to its inner side.

[0027] The inner walls of the three limiting frames 9 are each provided with a slot 93, and the inner walls of the three slots 93 are each slidably connected to a slider 94. The inner sides of the three sliders 94 are each slidably connected to a connecting bracket 10. After the impurities and copper powder on the inner wall of the screening box 1 are separated, the feed hopper 2 is opened, and the connecting brackets 10 can be pulled to drive the sliders 94 to slide along the slots 93. This allows the three connecting brackets 10 to be removed from the inner walls of the three limiting frames 9. At the same time, the impurities screened by the precision filter screen 13, filter screen 12 and primary filter screen 11 can be cleaned.

[0028] See Figure 2 , Figure 3 The feed hopper 2 is perpendicular to the filter screen 12, the primary filter screen 11 and the connecting bracket 10. The filter screen 12, the primary filter screen 11 and the connecting bracket 10 are installed inside the three connecting brackets 10. The output end of the vibration device body 6 is fixedly connected to the bottom of the transmission rod 8, and the transmission rod 8 is sleeved on the bottom of the four limit rods 7.

[0029] The precision filter 13, filter 12, and primary filter 11 can be installed through three connecting brackets 10. Since the feed hopper 2 is perpendicular to the filter 12, primary filter 11, and connecting bracket 10, and the output end of the vibration device body 6 is fixedly connected to the bottom of the transmission rod 8, and the transmission rod 8 is sleeved on the bottom of the four limiting rods 7, the crushed circuit board metal conductor material can be fed into the inner wall of the screening box 1 through the feed hopper 2. The circuit board metal conductor material is located on top of the precision filter 13. When the vibration device body 6 is started, it can drive the transmission rod 8 and drive the three limiting frames 9 to vibrate along the outer wall of the four limiting rods 7, thereby causing the three limiting frames 9 to drive the precision filter 13, filter 12, and primary filter 11 to separate copper powder and impurities.

[0030] During operation, the feeding hopper 2, cover plate 3, safety door 4, vibrating device body 6, and four limiting rods 7 can be installed through the screening box 1. A transmission rod 8 is movably installed at the output end of the vibrating device body 6, located on the inner wall of the screening box 1. Three limiting frames 9 are slidably connected to the outer walls of the four limiting rods 7. Connecting brackets 10 are slidably connected inside each of the three limiting frames 9. A precision filter screen 13, a filter screen 12, and a primary filter screen 11 are sequentially installed inside each of the three connecting brackets 10, thereby pulverizing the circuit board metal. Conductor material can be fed into the inner wall of the screening box 1 through the feed hopper 2 and placed on top of the precision filter screen 13. The collection container is placed on top of the transmission rod 8. At this time, the main body of the vibration device 6 is activated, which can drive the transmission rod 8, the three limit frames 9, the three connecting brackets 10, and the precision filter screen 13, filter screen 12 and primary filter screen 11 to vibrate up and down along the four limit rods 7. This allows the precision filter screen 13, filter screen 12, connecting brackets 10 and the container to separate copper powder and impurities in the circuit board. The separation process is time-saving and labor-saving.

[0031] The inner walls of the three limiting frames 9 are each provided with a slot 93, and the inner walls of the three slots 93 are each slidably connected to a slider 94. The inner sides of the three sliders 94 are each slidably connected to a connecting bracket 10. After the impurities and copper powder on the inner wall of the screening box 1 are separated, the feed hopper 2 is opened, and the connecting brackets 10 can be pulled to drive the sliders 94 to slide along the slots 93. This allows the three connecting brackets 10 to be removed from the inner walls of the three limiting frames 9. At the same time, the impurities screened by the precision filter screen 13, filter screen 12 and primary filter screen 11 can be cleaned.

[0032] The precision filter 13, filter 12, and primary filter 11 can be installed through three connecting brackets 10. Since the feed hopper 2 is perpendicular to the filter 12, primary filter 11, and connecting bracket 10, and the output end of the vibration device body 6 is fixedly connected to the bottom of the transmission rod 8, and the transmission rod 8 is sleeved on the bottom of the four limiting rods 7, the crushed circuit board metal conductor material can be fed into the inner wall of the screening box 1 through the feed hopper 2. The circuit board metal conductor material is located on top of the precision filter 13. When the vibration device body 6 is started, it can drive the transmission rod 8 and drive the three limiting frames 9 to vibrate along the outer wall of the four limiting rods 7, thereby causing the three limiting frames 9 to drive the precision filter 13, filter 12, and primary filter 11 to separate copper powder and impurities.

[0033] In summary, when the device starts the main body 6 of the vibration device, it drives the transmission rod 8, the three limit frames 9, the three connecting brackets 10, and the precision filter 13, filter 12 and primary filter 11 to vibrate up and down along the four limit rods 7, so that the precision filter 13, filter 12 and connecting bracket 10 can separate copper powder and impurities in the circuit board, and the separation process is time-saving and labor-saving.
