Technical Field

[0001] This utility model relates to the technical field of dust removal devices, specifically a circuit board recycling and cleaning dust removal device. Background Technology

[0002] Circuit board recycling and cleaning dust removal equipment is an environmentally friendly device in the process of electronic waste resource utilization. Its main function is to remove dust, debris and other pollutants from the surface of waste circuit boards by physical means, in preparation for subsequent recycling. The device can vacuum the cleaned circuit boards and collect the dust through the vacuum system to prevent secondary pollution.

[0003] However, in existing circuit board recycling, cleaning, and dust removal devices, the top and sides of the circuit board are not easily positioned simultaneously during use, which may cause shaking or displacement during the dust removal process. If the board falls off, it may damage the board. Therefore, those skilled in the art have provided a circuit board recycling, cleaning, and dust removal device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a circuit board recycling, cleaning, and dust removal device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A circuit board recycling, cleaning, and dust removal device includes a dust removal cabinet. A vacuum cleaner is installed on the top of the dust removal cabinet. A dust suction hood is connected to the bottom of the vacuum cleaner via a pipe. A dust filter bag placement housing is provided on one side of the vacuum cleaner. A movable door is hinged to the outside of the dust filter bag placement housing via a hinge. A positioning mechanism is installed on the inner bottom wall of the dust removal cabinet. A closing mechanism is provided on the outside of the dust filter bag placement housing. The positioning mechanism includes a placement frame, an electric push rod fixed to the top of the placement frame, a roller bracket mounted on the top of the output shaft of the electric push rod, a top positioning frame rotatably connected to the top of the roller bracket via a rotating shaft, a side limiting frame rotatably connected to the outside of the placement frame via a rotating shaft, a placement plate fixed to the outside of the placement frame, a limiting connecting rod mounted on the outside of the placement frame, a positioning head provided at one end of both the side limiting frame and the top positioning frame, and a tension spring provided between the side limiting frame and the placement frame.

[0006] As an improvement of this utility model: the top of the roller bracket is equipped with a bracket, and a roller is rotatably connected inside the bracket via a rotating shaft. The corresponding surface of the roller is in contact with the side limiting frame.

[0007] As an improvement of this utility model: the placement rack and the dust removal cabinet are fixedly connected, and the top positioning rack has a guide groove inside that matches the size of the limiting connecting rod.

[0008] As an improvement of this utility model: the closing mechanism includes a guide plate, an anti-disengagement slider is slidably connected to the outer side of the guide plate through a slide groove, a locking plate is fixed to the outer side of the anti-disengagement slider, an assembly plate is fixed to the outer side of the movable door, a limit sleeve is fixed to the outer side of the assembly plate, a threaded post is fixed to the outer side of the assembly plate, and a metal nut is threadedly connected to the outer side of the threaded post.

[0009] As an improvement of this utility model: the guide plate and the dust filter bag housing are fixedly connected, and the corresponding surface of the locking plate is fitted with the assembly plate.

[0010] As an improvement of this utility model: the locking plate has a groove inside, the size of which is adapted to the size of the threaded post.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By incorporating a positioning mechanism, the circuit board is simultaneously and automatically clamped on the sides and top without manual intervention, significantly improving operational efficiency. Through the combined constraint of the sides and top, this mechanism completely restricts the circuit board's freedom of movement in both the horizontal and vertical directions. This ensures that during subsequent cleaning and dust removal processes, the board will not loosen, shift, or tip over due to airflow impact or other external forces, improving the consistency of dust removal effects and reducing collisions and scratches caused by board movement. This protects the integrity of the circuit board and facilitates subsequent recycling processes.

[0012] 2. The closure mechanism allows for easy release of the locking plate's obstruction of the mounting plate fixed to the movable door. This enables easy opening of the movable door for maintenance. The entire process requires no complex tools, and the operation is simple and intuitive, significantly reducing labor intensity and time. After maintenance, close the movable door, push the locking plate 73 to reset it, and retighten the metal nut 77 to complete the locking. This mechanical connection method provides structural stability, ensuring the movable door 5 remains tightly closed during equipment operation, preventing dust escape and guaranteeing the sealing performance and effectiveness of the dust removal system.

[0015] The technical solution of this utility model will be further described in detail below with reference to specific embodiments: First Embodiment Please see Figures 1-5 A circuit board recycling, cleaning, and dust removal device includes a dust removal cabinet 1, a vacuum cleaner 2 installed on the top of the dust removal cabinet 1, a dust suction hood 3 connected to the bottom of the vacuum cleaner 2 via a pipe, a dust filter bag placement housing 4 provided on one side of the vacuum cleaner 2, a movable door 5 hinged to the outside of the dust filter bag placement housing 4, a positioning mechanism 6 installed on the inner bottom wall of the dust removal cabinet 1, and a closing mechanism 7 provided on the outside of the dust filter bag placement housing 4. The positioning mechanism 6 includes a placement frame 61, an electric push rod 62 fixed to the top of the placement frame 61, a roller bracket 63 mounted on the top of the output shaft of the electric push rod 62, a top positioning frame 64 rotatably connected to the top of the roller bracket 63 via a rotating shaft, a side limiting frame 65 rotatably connected to the outside of the placement frame 61 via a rotating shaft, a placement plate 66 fixed to the outside of the placement frame 61, a limiting connecting rod 67 mounted on the outside of the placement frame 61, a positioning head 68 provided at one end of both the side limiting frame 65 and the top positioning frame 64, a tension spring 69 provided between the side limiting frame 65 and the placement frame 61, a bracket mounted on the top of the roller bracket 63, a roller rotatably connected inside the bracket via a rotating shaft, the corresponding surface of the roller fitting against the side limiting frame 65, the placement frame 61 and the dust removal cabinet 1 fixedly connected, and a guide groove adapted to the size of the limiting connecting rod 67 being opened inside the top positioning frame 64.

[0016] With the above setup, when recycling, cleaning, and dusting the circuit board, the circuit board is placed on the placement plate 66. After the electric push rod 62 is activated, the roller bracket 63 moves vertically. After the roller bracket 63 moves downward, the tension spring 69 provides tension to rotate one end of the side limiting bracket 65, so that the positioning head 68 at the other end of the side limiting bracket 65 presses and adheres to the side of the circuit board. At the same time, the roller bracket 63 drives one end of the top positioning bracket 64 to rotate, so that the corresponding surface of the positioning head 68 at the other end of the top positioning bracket 64 presses and adheres to the top of the circuit board. This allows for convenient simultaneous positioning of the side and top during the recycling, cleaning, and dusting of the circuit board, thereby restricting the freedom of the circuit board in the horizontal and vertical directions, preventing it from loosening and falling off due to wind, reducing damage to the board material, and facilitating the recycling, cleaning, and dusting of the circuit board.

[0017] In summary, after the operator places the circuit board on the placement plate 66 and activates the electric push rod 62, the electric push rod 62 pulls down the roller bracket 63. This action, through mechanical linkage, on the one hand, under the tension of the tension spring 69, drives the positioning head 68 at one end of the side limiting bracket 65 to press against the side of the circuit board; on the other hand, it drives the top positioning bracket 64 to rotate, causing its end positioning head 68 to press down and fit against the top of the circuit board. This design achieves synchronous automated clamping of the side and top of the circuit board without manual intervention, significantly improving operational efficiency. Through the joint constraint of the side and top, the mechanism completely restricts the degree of freedom of the circuit board in the horizontal X and Y axes and the vertical Z axis. This ensures that during the subsequent cleaning and dust removal process of the circuit board, the board will not loosen, shift, or tip over due to airflow impact or other external forces, improving the consistency of dust removal effect and reducing collisions and scratches caused by board movement, protecting the integrity of the circuit board, and facilitating the subsequent recycling and reuse process.

[0018] Second Embodiment Please see Figures 1-5 Based on the first embodiment, the closing mechanism 7 includes a guide plate 71. An anti-detachment slider 72 is slidably connected to the outer side of the guide plate 71 via a slide groove. A locking plate 73 is fixed to the outer side of the anti-detachment slider 72. An assembly plate 74 is fixed to the outer side of the movable door 5. A limit sleeve 75 is fixed to the outer side of the assembly plate 74. A threaded post 76 is fixed to the outer side of the assembly plate 74. A metal nut 77 is threadedly connected to the outer side of the threaded post 76. The guide plate 71 and the dust filter bag housing 4 are fixedly connected. The corresponding surface of the locking plate 73 is in contact with the assembly plate 74. A groove is provided inside the locking plate 73. The size of the groove is adapted to the size of the threaded post 76.

[0019] With the above-mentioned setup, and the presence of the closing mechanism 7, when it is necessary to open the movable door 5 to replace or clean the dust filter bags inside the dust filter bag housing 4, simply rotate the metal nut 77 on the outside of the threaded column 76, so that the corresponding surface of the metal nut 77 is away from the locking plate 73, and then move the locking plate 73 vertically. This will allow the anti-detachment slider 72 to slide in the groove of the guide plate 71, and release the blocking and limiting effect of the locking plate 73 on the assembly plate 74, thereby conveniently opening the movable door 5 to replace or clean the dust filter bags inside the dust filter bag housing 4. The operation is relatively simple.

[0020] In summary, when it is necessary to replace or inspect the filter bags placed inside the housing 4, maintenance personnel only need to loosen the metal nut 77, allowing it to retract along the threaded post 76 and no longer press against the locking plate 73. This easily releases the locking plate 73 from obstructing the mounting plate 74 fixed to the movable door 5. At this point, the movable door 5 can be easily opened for maintenance. The entire process requires no complicated tools, and the operation steps are simple and intuitive, greatly reducing labor intensity and time required. After maintenance, the movable door 5 is closed, the locking plate 73 is pushed to reset, and the metal nut 77 is retightened to complete the locking. This mechanical connection method has a stable structure and ensures that the movable door 5 is tightly closed during equipment operation, preventing dust from escaping and ensuring the sealing performance and working efficiency of the dust removal system.

[0021] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
