The device includes an outer cylinder, inside which a roller is fitted, and a screening frame is provided on the outer ring of the roller. It also includes a triggering component located on the side of the top of the outer cylinder. The triggering component monitors the position of the screening frame. The middle end of the screening frame is movably connected to the roller via a movable shaft. When the screening frame deflects due to hooking a circuit board, it contacts the triggering component. This invention uses the triggering component to determine the hooking signal and control a striking component to operate.

Description

Technical Field

[0001] This invention relates to the field of recycling and dismantling technology, specifically to a household appliance recycling and dismantling device. Background Technology

[0002] A waste home appliance dismantling line is a device that can dismantle, classify, and sort waste home appliances. It can classify and recycle various materials in home appliances for reuse. Home appliance recycling and dismantling generally requires dismantling the plastic shell and internal hardware. The plastic shell is crushed by a plastic crusher to break down the plastic products into granules for the production of recycled plastics. The circuit board dismantling machine dismantles the circuit boards of the internal hardware. Different components contain different metals. The dismantled motherboard is easier to crush and decompose the copper in it, reducing the crushing and sorting work. The metal crusher can crush the metal products into granules for the reuse of metals.

[0003] A circuit board dismantling machine typically consists of a motor, a shaft, a drum, a heating element, a screen, and a recycling bin. The drum rotates with the shaft, and the heating element is located in the center of the drum. The heating nozzle is located inside the shaft. The high temperature loosens the solder on the circuit board. As the drum rotates, the circuit board collides and rubs against the inner wall of the drum, and the electronic components gradually fall off the circuit board. The drum wall is evenly provided with perforations. The small electronic components that fall off are thrown out through the perforations of the drum, and the remaining parts fall into the recycling bin along the screen.

[0004] However, the surface of the undisassembled circuit board contains small components such as resistors and capacitors. When multiple circuit boards are piled up at the bottom of the drum, the bottom circuit board is subjected to pressure, which makes it easy for the small components on the bottom circuit board to hook onto the mesh rod of the strain net and not fall off easily. If the circuit board is hooked onto the strain net, the distance between the circuit board and the heating component is relatively far, and the solder points on the circuit board melt too slowly, making it difficult to loosen the electronic components and reducing the disassembly speed. Therefore, a household appliance recycling and disassembly equipment is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a household appliance recycling and dismantling device to solve the problems mentioned in the background art, such as small components of the bottom circuit board getting caught on the mesh rod of the strainer and not falling off easily, the circuit board being caught on the strainer, the distance between the circuit board and the heating component being too far, the solder points on the circuit board melting too slowly, making it difficult to loosen the electronic components and reducing the dismantling speed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a household appliance recycling and dismantling device, comprising an outer cylinder, an inner sleeve of a roller, and a screening frame provided on the outer ring of the roller;

[0007] It also includes a triggering component, which is located on the side of the top of the outer cylinder. The triggering component is used to monitor the position of the screening frame. The middle of the screening frame is movably connected to the roller through a movable shaft. When the screening frame deflects due to hooking the circuit board, the screening frame contacts the triggering component. The triggering component determines the circuit board hooking signal.

[0008] The reset component is located on the surface of the filter frame. The reset component presses against the deflection of the filter frame, which helps the filter frame to return to its original position after the circuit board and the filter frame detach.

[0009] The striking component is located on the top of the outer cylinder. After the trigger component detects the trigger signal, the controller controls the striking component to work. The striking component strikes the circuit board hooked on the screening frame, which helps to remove the hooked circuit board.

[0010] The triggering component includes a contact plate that presses against the surface of the roller, with the side of the contact plate away from the roller inserted into the interior of the fixed base. A spring is provided between the contact plate and the inner wall of the fixed base. A contact point is fixed on the end face of the contact plate away from the roller, and a contact point two that cooperates with the contact point one is fixed on the inner wall of the fixed base.

[0011] The side of the touch plate closest to the roller is curved, and both sides of the screening frame are curved.

[0012] The reset assembly includes a second spring that presses against the surface of the screening frame, and the end of the second spring away from the screening frame is fixed to the surface of the first fixing frame. The end face of the first fixing frame is fixed to the surface of the roller, and the inside of the roller has an opening that cooperates with the screening frame.

[0013] The striking assembly includes a movable plate inserted inside the outer cylinder, and a striking rod is fixed on the side of the movable plate near the roller. A push plate is fixed on the top of the movable plate, and the top of the push plate is movably connected to a rotating plate through a movable shaft two. The side of the rotating plate one away from the push plate is movably connected to a rotating plate two through a rotating rod one. The side of the rotating plate two away from the rotating rod one is fixedly connected to the output shaft of the motor through a rotating rod two.

[0014] Among them, the outer side of the rotating plate is fitted with a fixed frame 2. The bottom of the fixed frame 2 is fixed to the surface of the outer cylinder. The output shaft of the motor is movably connected to the fixed frame 2. The bottom of the motor is fixedly connected to the surface of the fixed frame 2 through a bracket.

[0015] Among them, limit plates are fixed on both sides of the push plate, and the limit plates are inserted into the inside of the second fixed frame. The inside of the second fixed frame is provided with a limit groove that cooperates with the limit plate.

[0016] The screening frame is equipped with an adjustable distance assembly, which includes a fixed rod fixed to the inner wall of the screening frame, a movable rod on the side of the fixed rod, an insert rod fixed to the side of the movable rod, and the end of the insert rod away from the movable rod inserted into the inside of the fixed rod. A spring is fixed between the insert rod and the fixed rod. A spring sheet is fixed to the side of the movable rod away from the roller. A pressure plate that cooperates with the spring sheet is fixed to the side of the inner wall of the outer cylinder.

[0017] The bottom of the pressure plate is curved, and rubber bumps are glued to the surface of the spring sheet.

[0018] This invention has at least the following beneficial effects:

[0019] The trigger component determines the hooking signal and controls the striking component to work. The striking component strikes the gaps in the screening frame, which helps the circuit boards hooked on the surface of the screening frame to fall off. The bottom circuit boards that are hooked fall onto the heating source surface in the center of the roller, allowing the bottom circuit boards to come into close contact with the heating source. This facilitates the melting of the solder joints on the bottom circuit boards, making it easier for the electronic components to fall off and be disassembled. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figure 1-8 The present invention provides a technical solution: a household appliance recycling and dismantling device, including an outer cylinder 11, a roller 12 is sleeved inside the outer cylinder 11, and a screening frame 2 is provided on the outer ring of the roller 12;

[0035] It also includes a trigger component 3, which is located on the side of the top of the outer cylinder 11. The trigger component 3 is used to monitor the position of the screening frame 2. The middle end of the screening frame 2 is movably connected to the roller 12 through a movable shaft. When the screening frame 2 deflects due to hooking the circuit board, the screening frame 2 contacts the trigger component 3. The trigger component 3 is used to determine the circuit board hooking signal.

[0036] Reset component 4 is disposed on the surface of the filter frame 2. The reset component 4 presses against the deflection of the filter frame 2, which helps the filter frame 2 to return to its original position after the circuit board and the filter frame 2 are detached.

[0037] The striking component 5 is located at the top of the outer cylinder 11. After the trigger component 3 detects the trigger signal, the controller controls the striking component 5 to work. The striking component 5 strikes the circuit board hooked on the screening frame 2, which helps to detach the hooked circuit board. When the bottom circuit board is hooked on the surface of the screening frame 2 and cannot be detached, the circuit board pulls the screening frame 2. With the cooperation of the movable shaft 1, the screening frame 2 is deflected, and one end of the screening frame 2 protrudes out of the screening frame 2. The bottom of the protruding screening frame 2 contacts the trigger component 3, triggering the trigger component 3. The trigger component 3 judges the hooking signal and transmits the signal to the controller. The controller controls the striking component 5 to work. The striking component 5 strikes the gaps in the screening frame 2. The circuit board hooked on the surface of the screening frame 2 is knocked off and falls to the surface of the heating source in the center of the drum 12. This allows the bottom circuit board to come into close contact with the heating source, which helps to melt the solder points of the bottom circuit board and facilitates the detachment of the electronic components, thus realizing the disassembly of the electronic components.

[0038] The triggering component 3 includes a contact plate 31 that presses against the surface of the roller 12, with the side of the contact plate 31 away from the roller 12 inserted into the interior of the fixing base 32. A spring 33 is provided between the contact plate 31 and the inner wall of the fixing base 32. A contact point 34 is fixed on the end face of the contact plate 31 away from the roller 12. A contact point 35 that cooperates with the contact point 34 is fixed on the inner wall of the fixing base 32. When the screening frame 2 deflects due to hooking the circuit board, one end of the screening frame 2 protrudes from the inside of the roller 12. The protruding part of the screening frame 2 presses against the contact plate 31. After being pressed, the contact plate 31 retracts into the interior of the fixing base 32. At this time, the spring 33 is in a compressed and stored state. The contact point 34 contacts the contact point 35 and transmits the contact signal to the controller, so that the controller can control the operation of the striking component 5. The striking component 5 is used to strike the hooked circuit board, which is conducive to the removal of the circuit board.

[0039] The side of the touch plate 31 closest to the roller 12 is set to be arc-shaped, and the two sides of the screening frame 2 are set to be arc-shaped. The arc-shaped design of the touch plate 31 and the screening frame 2 makes it easier for the screening frame 2 to press against the touch plate 31 and push the touch plate 31 to move, so that the contact between the touch plate 31 and the screening frame 2 is smoother.

[0040] The reset assembly 4 includes a second spring 42 that presses against the surface of the screening frame 2. The end of the second spring 42 away from the screening frame 2 is fixed to the surface of the first fixing frame 41. The end face of the first fixing frame 41 is fixed to the surface of the roller 12. The roller 12 has an opening 43 inside that cooperates with the screening frame 2. By pressing the surface of the screening frame 2 with the second spring 42, after the circuit board of the screening frame 2 is deflected due to the pulling of the circuit board, the surface of the screening frame 2 presses against the second spring 42, so that the second spring 42 is in a compressed and stored state. When the circuit board falls off, the second spring 42 presses against and pushes the screening frame 2, which helps the screening frame 2 to return to its original position.

[0041] The striking assembly 5 includes a movable plate 51 inserted inside the outer cylinder 11, with a striking rod 52 fixed to the side of the movable plate 51 near the roller 12. A push plate 53 is fixed to the top of the movable plate 51, and the top of the push plate 53 is movably connected to a rotating plate 54 via a second movable shaft. The side of the rotating plate 54 away from the push plate 53 is movably connected to a second rotating plate 56 via a first rotating rod 55. The surface of the second rotating plate 56 away from the first rotating rod 55 is fixedly connected to the output shaft of the motor 58 via a second rotating rod 57. When the controller receives a signal from the trigger assembly 3... Upon receiving the signal, the controller activates motor 58, which in turn drives rotating plate 56 via rotating rod 57. Rotating plate 56 rotates around rotating rod 57, and rotating plate 56 drives rotating plate 54 to move synchronously via rotating rod 55. Rotating plate 54 pushes push plate 53 to move vertically, and push plate 53 drives striking rod 52 to move vertically synchronously via moving plate 51. The vertical movement of striking rod 52 can strike the gaps in the grid of the screening frame 2, which helps to remove the circuit board hooked on the surface of the screening frame 2.

[0042] A second fixing frame 59 is fitted around the outside of the rotating plate 54. The bottom of the second fixing frame 59 is fixed to the surface of the outer cylinder 11. The output shaft of the motor 58 is movably connected to the second fixing frame 59. The bottom of the motor 58 is fixedly connected to the surface of the second fixing frame 59 through a bracket. The second fixing frame 59 protects the push plate 53, the rotating plate 54, the rotating rod 55, the rotating plate 56, and the rotating rod 57, preventing external objects from impacting the rotation of the rotating plate 54. At the same time, the second fixing frame 59 supports and fixes the motor 58, making the installation of the motor 58 more stable.

[0043] Limiting plates 61 are fixed on both sides of the push plate 53, and the limiting plates 61 are inserted into the inside of the second fixing frame 59. The inside of the second fixing frame 59 is provided with a limiting groove 62 that cooperates with the limiting plate 61. The pushing plate 53 is limited by the limiting plate 61, making the vertical movement of the pushing plate 53 more stable and preventing it from rotating with the first rotating plate 54, thus improving the stability of the movement of the pushing plate 53.

[0044] Example 2

[0045] Please see Figure 9-11The screening frame 2 is internally equipped with an adjustment assembly 7. The adjustment assembly 7 includes a fixed rod 71 fixed to the inner wall of the screening frame 2, and a movable rod 72 is provided on the side of the fixed rod 71. An insert rod 73 is fixed to the side of the movable rod 72, and the end of the insert rod 73 away from the movable rod 72 is inserted into the interior of the fixed rod 71. A spring 74 is fixed between the insert rod 73 and the fixed rod 71. A spring piece 75 is fixed to the side of the movable rod 72 away from the roller 12. A pressure plate 76 that cooperates with the spring piece 75 is fixed to the side of the inner wall of the outer cylinder 11. When the screening frame 2 rotates to the bottom of the outer cylinder 11, the bottom circuit board is pressed against the surface of the screening frame 2, and the screening frame 2 rotates with the roller 12. Subsequently, the spring piece 75 is pressed by the pressure plate 76. After being pressed, the spring piece 75 undergoes elastic deformation. At the same time, the spring piece 75 synchronously presses the movable rod 72. After being pressed, the movable rod 72 moves towards the fixed rod 71. The movable rod 72 pushes the insert rod 73 to move synchronously. At this time, the spring... Spring 74 is in a compressed, stored state, which changes the distance between the movable rod 72 and the fixed rod 71. By reducing the distance between the fixed rod 71 and the movable rod 72, some electronic components on the surface of the circuit board are easily clamped by the fixed rod 71 and the movable rod 72, thus facilitating the bottom circuit board to hook onto the surface of the screening frame 2. When the contact between the spring 75 and the pressure plate 76 is released, the movable rod 72 returns to its initial position. At the same time, spring 74 returns to its initial state, the distance between the movable rod 72 and the fixed rod 71 increases, and the clamped circuit board falls off. Through the above design, it is beneficial for the bottom circuit board to be hooked by the screening frame 2 and to flip and fall off after hooking, increasing the flipping effect of the circuit board and facilitating the squeezing between the circuit boards, thus facilitating the electronic components to fall off due to mutual squeezing. At the same time, the bottom circuit board flips to the top layer, so that the flipped circuit board comes into close contact with the heating source, which facilitates the melting of the solder points of the bottom circuit board and makes the melting effect of the circuit board inside the roller 12 more uniform.

[0046] The bottom of the pressure plate 76 is arc-shaped, and the surface of the spring piece 75 is glued with rubber protrusions. The arc-shaped design facilitates the contact between the spring piece 75 and the pressure plate 76, making it easier for the pressure plate 76 to press against the spring piece 75. The pressing of the spring piece 75 pushes the movable rod 72 to move. The design of the rubber protrusions increases the friction between the spring piece 75 and the pressure plate 76, thereby facilitating the movement of the movable rod 72 by the spring piece 75.

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
