Detailed Implementation
[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 Figures 1-3This utility model provides a metal circuit board recycling and screening device, including a base plate 5. Multiple L-shaped plates 20 are bolted to the top of the base plate 5. The L-shaped plates 20 are located at the four corners of a collection box 6, and the inner walls of the L-shaped plates 20 are in contact with the outer walls of the collection box 6. The L-shaped plates 20 ensure the correct installation and positioning of the collection box 6 through precise positioning. A fixing frame 4 is bolted to the top of the base plate 5. A conveyor belt 2 is located between the inner walls of both sides of the fixing frame 4 and at the top. Multiple equally spaced partitions 3 are bonded to the upper surface of the conveyor belt 2. A limiting space for the circuit board is formed between every two equally spaced partitions 3, achieving effective and orderly placement of the circuit board.The circuit boards are stacked. A support frame 10 is bolted to the top of the base plate 5. A baffle 7 is rotatably connected to the top of the support frame 10 via bearing seats. Two stops are bolted to the top of the baffle 7, forming a protective barrier to prevent the circuit boards from detaching from the baffle 7 and falling outside the collection box 6. Two slide rails 8 are bolted to the bottom of the baffle 7. A dual-axis cylinder 11 is bolted to the top of the base plate 5. A connecting frame 12 is bolted to the two telescopic ends of the dual-axis cylinder 11. Two slide brackets 9, slidably connected to the two slide rails 8, are rotatably connected to the top of the connecting frame 12 via bearings. A pair of... The detection component for detecting metal circuit boards includes a receiving component located on the top of the base plate 5 and on both sides of the support frame 10. Each receiving component comprises two collection boxes 6 slidably connected to the top of the base plate 5 and on both sides of the support frame 10. Handles are bolted to both sides of each collection box 6. After the circuit boards are sorted, the handles on both sides of the collection box 6 are pulled simultaneously to detach the collection box 6 from the top of the base plate 5, achieving centralized collection and convenient transportation of the circuit boards. The conveyor belt 2 continuously transports the circuit boards to be detected to the area below the detection component. The detection component is then activated to identify metal and non-metal circuit boards. After detection, if the circuit board is metal, the detection component will transmit a strong electrical signal. The receiver analyzes the signal strength and transmits it to an externally connected control device. The external control device receives the strong electrical signal and activates the dual-axis cylinder 11. The telescopic end of the dual-axis cylinder 11 retracts, causing the connecting frame 12 to move downwards. As the connecting frame 12 moves downwards, the slide 9 rotates with it and slides along the slide rail 8, simultaneously causing the baffle 7 to rotate on top of the support frame 10. At this time, the baffle 7 is tilted, and the metal circuit board will fall along the baffle 7 into the collection box 6 near the dual-axis cylinder 11. Conversely, if the circuit board is non-metallic... The detection component emits a weak electrical signal. After analyzing the signal strength using a receiver, the signal is transmitted to an externally connected control device. Upon receiving this weak signal, the external control device activates the dual-axis cylinder 11. The piston end of the dual-axis cylinder 11 extends, pushing the connecting frame 12 upwards. The connecting frame 12 then rotates the slide 9, which continues to slide along the slide rail 8. As the dual-axis cylinder 11 continues to push, the baffle 7 tilts towards one end of the conveyor belt 2, causing the non-metallic circuit board to fall along the baffle 7 into another collection box 6, thus completing the screening of the circuit boards and achieving the sorting and screening of circuit boards containing metal.
[0023] In this embodiment: the detection component includes a mounting bracket 1 fixed to one side of the fixing frame 4 by bolts. Two slots are opened at the top of the mounting bracket 1, and guide rods 13 are slidably connected in each slot. One end of each guide rod 13 is fixed to a fixing block 15 by bolts. A metal detector 16 is provided at the bottom of the fixing block 15. The metal detector emits different signals depending on the amount of metal detected; for example, a stronger signal is emitted when there is more metal, and a weaker signal is emitted when there is less metal. A driving component for the fixing block 15 is provided at the top of the mounting bracket 1. The driving component includes a through-type threaded groove opened at the top of the mounting bracket 1, and a threaded rod 14 rotatably connected to the top of the fixing block 15 is threaded into the through-type threaded groove. Rotating the threaded rod 14 can drive the fixing block 15 to move up and down. The height of the metal detector 16 can be adjusted, enhancing its applicability. The limiting component includes two dovetail grooves 19 at the bottom of the fixed block 15, with sliders 17 slidably connected in each dovetail groove 19. Anti-slip pads 18 are adhered in each dovetail groove 19 and are in contact with the sliders 17. Through the insertion of the two sliders 17 into the two dovetail grooves 19, the sliders 17, through the friction generated with the anti-slip pads 18, prevent the sliders 17 from easily detaching from the dovetail grooves 19, facilitating the installation and removal of the metal detector 16 at the bottom of the two sliders 17. The bottom of the fixed block 15 is provided with a detachable limiting component for the metal detector 16. The specific model of the metal detector 16 is Bosch D-tect 120. Two guide rods 13 prevent the fixed block 15 from deviating from linear movement, enhancing the stability of the metal detector 16.
[0024] The working principle of this utility model is as follows: The circuit board to be tested is placed in the limited space formed by two partitions 3. By starting the conveyor belt 2, the circuit board to be tested is continuously conveyed to the area below the metal detector 16. The metal detector 16 identifies metal and non-metal circuit boards. After detection, if the circuit board is metal, the detection component will transmit a strong electrical signal. The receiver analyzes the signal strength and transmits it to the externally connected control device. The identification of metal and non-metal circuit boards is then activated, thereby activating the dual-axis cylinder 11. The dual-axis cylinder 11 drives the connecting frame 12 to move downward. As the connecting frame 12 moves downward, the slide 9 rotates with the connecting frame 12 and slides along the slide rail 8, which in turn drives the baffle 7 to support the circuit board. The top of the frame 10 rotates, at which point the baffle 7 is tilted. Metal circuit boards will fall along the baffle 7 into the collection box 6 near the side of the dual-axis cylinder 11. Conversely, for non-metal circuit boards, the detection component will transmit a weaker electrical signal. After the receiver analyzes the strength of the signal, it is transmitted to the externally connected control device. The externally connected control device will receive the weaker electrical signal and activate the dual-axis cylinder 11. The dual-axis cylinder 11 pushes the connecting frame 12 upward, which drives the slide 9 to rotate. At the same time, the slide 9 will continue to slide along the slide rail 8. As the dual-axis cylinder 11 continues to push, the baffle 7 will tilt towards one end of the conveyor belt 2. Non-metallic circuit boards will fall along the baffle 7 into another collection box 6, completing the screening and classification of circuit boards.
