Description

Technical Field

[0001] The invention relates to resource recovery technology, in particular to a device for disassembling components of waste circuit boards. Background Art

[0002] As is well known, electronic products, as a microcosm of the rapid development of modern science and technology, have brought great changes to consumers' lifestyles, and people also prefer to use updated electronic products. The recycling and treatment of electronic waste, especially circuit boards as an indispensable component of electronic products, has increased day by day. Waste circuit boards have extremely high resource value, containing a variety of non-ferrous metals and rare metals, and have extremely high resource recovery value. In addition, waste circuit boards have potential environmental hazards. For example, waste circuit boards also contain heavy metals such as lead, chromium, cadmium and mercury. If they are not handled or disposed of properly, they will cause environmental hazards. Therefore, the reasonable recycling and treatment of waste circuit boards is of great significance to the recycling of metal resources and environmental protection.

[0003] The electronic component disassembly machine currently used places the electronic components in a disassembly drum, first feeds the waste circuit boards into the drum through the feed port, and the drum starts to rotate, separating the electronic components from the circuit boards through centrifugal force, friction, etc., while heating to melt the solder to assist in disassembly; then the disassembled electronic components and circuit board bare plates are screened in the drum, and smaller electronic components fall through the screen or other means, while larger circuit board bare plates remain in the drum or are discharged from the larger outlet; finally, the separated electronic components and circuit board bare plates are transported to the corresponding collection devices through the discharge port, completing the entire disassembly work.

[0004] The disadvantage of the prior art is that, when the current disassembling machine is used for disassembly, a sealing door plate is generally provided on the surface of the disassembly cylinder. After the disassembly is completed, it is generally necessary to open the sealing plate of the disassembly cylinder and then add the waste circuit boards into the disassembly cylinder. However, when the circuit boards are disassembled in the disassembly cylinder, it is necessary to heat the inside of the disassembly cylinder to a certain temperature before disassembly. Therefore, the temperature in the disassembly cylinder will be relatively high. However, when adding the waste circuit boards, after the sealing plate is opened, the space in the disassembly cylinder is completely connected to the outside, and the high-temperature air in the disassembly cylinder will be discharged to the outside. The discharged high-temperature air will not only cause harm to the staff adding the waste circuit boards, but also after the high temperature in the disassembly cylinder is discharged, the inside of the disassembly cylinder needs to be heated again, which affects the disassembly efficiency of the waste circuit boards.

[0055] In another embodiment provided by the present invention, preferably, a sieve plate 7 is installed at the bottom of the frame 1, and the sieve plate 7 is arranged below the outer cylinder 2 and is compatible with the filter plate 13 arranged at the bottom of the outer cylinder 2. A control cabinet 6 is fixedly installed on one side of the frame 1, and a handle 3 is fixedly installed on the top of the surface of the outer door panel 4.

[0056] When removing electronic components from the surface of waste circuit boards, the specific steps are as follows:

[0057] A. After the rack 1 is powered on, open the outer door panel 4;

[0058] B. Place the circuit board through the outer door panel 4 into the cavity 20 opened between the outer tube 2 and the inner tube 8;

[0059] C. Close the outer door panel 4 and start the machine through the control cabinet 6;

[0060] D. Place the recycling frame of electronic components at the end of the sieve plate 7 and place the recycling frame of waste circuit boards at the discharge valve at the bottom of the rack 1.

[0061] The actions between the structures generated in the above operation steps are as follows:

[0062] In step A, during the process of opening the outer door panel 4, the outer door panel 4 is flipped and opened from top to bottom with the bottom as the center by grabbing the handle 3. During this process, when the outer door panel 4 rotates, the rotating wheels 11 installed at the bottom of both sides of the outer door panel 4 are inserted into the rotating grooves 14 opened in the inner side walls at both ends of the outer cylinder 2 for rotation. While the rotating wheel 11 rotates, the cam 12 set on one side is rotated to a contact state with the interference rod 19. The interference rod 19 slides from the surface of the rotating wheel 11 to the surface of the cam 12. The interference rod 19 is limited by the size of the cam 12, so that the interference rod 19 drives the rack 18 connected at the bottom end to be inserted into the inner cylinder 8, thereby driving the gear 17 meshing and connected above to rotate counterclockwise through the rack 18. The gear 17 is fixedly installed at the bottom positions at both ends of the inner door panel 10. Therefore, the counterclockwise rotation of the gear 17 will drive the inner door panel 10 to rotate and open in the inner door frame 31 opened on the surface of the inner cylinder 8 in a closed state, and due to the existence of the cam 12, the interference and extrusion of the interference rod 19 and the rack 18 is maximized. Therefore, at this time, the inner door panel 10 will be fully opened outwards and the clamping plate 16 arranged on the outer side of the top end of the inner door panel 10 will be inserted into the bottom end of the folding groove 25 opened on the inner side wall of the outer tube 2 above the outer door frame 5, and the clamping plate 16 will be inserted into the folding groove 25, so that the clamping plate 16 will squeeze and resist the bottom end of the sealing plate 24 rotatably installed in the folding groove 25 through the torsion spring shaft 26. At this time, the bottom end and the top end of the sealing plate 24 form a lever principle under the action of the torsion spring shaft 26, so that By squeezing the bottom end of the sealing plate 24, the top end of the sealing plate 24 pops outward and fits to the surface of the inner tube 8. At this time, the inner door frame 31 of the inner tube 8 is opened, but at the same time, the outside of the inner door frame 31 of the inner tube 8 is closed by the inner door plate 10 and the sealing plate 24. Therefore, at this time, a sealed state is formed between the inner tube 8, the inner door plate 10 and the sealing plate 24, so that the high-temperature air generated by the heating rod 15 in the inner tube 8 is sealed in the inner tube 8. At this time, the outer door plate 4 is opened, and step B can be performed;

[0063] In step B, after the outer door panel 4 is fully opened, since the outer door panel 4 is flipped open from top to bottom, during the opening process, the hot air in the cavity 20 will be discharged upward along the guide of the outer door panel 4. Therefore, when the outer door panel 4 is fully opened to a horizontal state, the personnel directly face the outer door frame 5 and will not be directly discharged to the face by the high-temperature hot air, which will cause danger. At this time, the personnel can put the waste circuit boards into the cavity 20 between the outer tube 2 and the inner tube 8 through the outer door frame 5. After a certain number of waste circuit boards are put into the cavity 20, step C can be performed;

[0064] In step C, during the process of closing the outer door panel 4, the outer door panel 4 is flipped upward to reset the rotary wheel 11, and the cam 12 and the resistance rod 19 that were originally in contact with each other are gradually slid apart, and the resistance rod 19 is slid to the surface of the rotary wheel 11. Through the contact of the surface of the rotary wheel 11 with the resistance rod 19, the bottom end of the rack 18 is connected to the inner wall of the inner tube 8, and the automatically rotating torsion spring shaft 26 connected between the gear 17 and the inner door frame 31, so that the rack 18 and the resistance rod 19 are rebounded outward to separate the resistance rod 19 from the cam 12 and The wheels 11 are in close sliding contact with each other. At this time, since the outer door panel 4 is completely closed, the resistance of the cam 12 surface of the resistance rod 19 is transformed into the resistance of the surface of the wheel 11. Due to the size of the wheel 11 itself, it will also produce a certain distance of resistance to the resistance rod 19, but the resistance distance is smaller than that of the cam 12. Therefore, when the resistance rod 19 receives the resistance of the cam 12 surface, the inner door panel 10 will shrink inward until the top of the clamping plate 16 is attached to the inner wall of the outer tube 2. At this time, the clamping plate 16 loses the resistance to the bottom end of the sealing plate 24, and the torsion spring shaft 26 drives the sealing plate 24 to reset.

[0065] When the inner cylinder 8 is started to rotate, in the first circle, the inner door panel 10 is in an open state. When it rotates to the downward position, the inner door panel 10 and the clamping plate 16 are used to guide the waste circuit board placed in the cavity 20 into the inner cylinder 8. When the inner cylinder 8 rotates one circle and reaches the corresponding position of the inner door panel 10 and the outer door panel 4, the abutment rod 19 abuts against the surface of the rotating wheel 11 again. The rotation of the inner cylinder 8 is a continuous process. Therefore, the abutment between the rotating wheel 11 and the abutment rod 19 is a simple contact. This abutment can close the inner door panel 10, thereby heating the waste circuit board inside the inner cylinder 8 and the electrons on the surface The components are disassembled, and in the third circle, after the resistance rod 19 contacts the rotating wheel 11 again, the inner door panel 10 is opened again, and the removed electronic components can be discharged into the cavity 20 through the opened inner door panel 10, and the filter plate 13 is also arranged at the bottom of the inner cylinder 8 to discharge the electronic components. At the same time, the opened inner door panel 10 contacts the inner wall of the outer cylinder 2 and rotates, and the surface of the filter plate 13 arranged at the bottom of the outer cylinder 2 can be automatically cleaned through the inner door panel 10, and the circuit board received in the position or discharged from the inner cylinder 8 is recycled into the inner cylinder 8, so that the inner door panel 10 can be opened and closed after the inner cylinder 8 rotates two circles;

[0066] It should be noted that in order to realize that the inner door panel 10 can be switched between the open and closed states every time the inner cylinder 8 rotates one circle, a circulation mechanism is provided between the rack 18 and the inner side wall of the inner cylinder 8:

[0067] The circulation structure is provided with a slide groove A21, a slide groove B27, a slide groove C29 and a clamping groove 28. When the resistance rod 19 rotates to the position of the rotating wheel 11, the resistance rod 19 is resisted by the size of the rotating wheel 11, and the slide rod 23 can be pressed upward to the surface of the guide plate 30 in the slide groove A21. After the inner cylinder 8 rotates, the rotating wheel 11 loses the pressure on the resistance rod 19, and the rack 18 is reset, so that the slide rod 23 can slide along the surface of the guide plate 30 to the clamping groove 28 for fixing. At this time, since the slide rod 23 is located in the clamping groove 28, the inner door panel 10 is in an open state.

[0068] After one rotation, when the rotating wheel 11 contacts the abutting rod 19 again, the abutting rod 19 is squeezed out of the slot 28 into the slide slot B27. At this time, after the rotating wheel 11 and the abutting rod 19 are separated, the slide bar 23 slides along the slide slot B27 to the position where the bottom end is connected to the slide slot A21. At this time, the rack 18 is pulled outward, and the inner door panel 10 is driven by the gear 17 to close under the rotation of the torsion spring shaft 26.

[0069] When the outer door panel 4 is opened when the rotating wheel 11 contacts the abutment rod 19, the rotating wheel 11 rotates and the cam 12 abuts the abutment rod 19. At this time, the sliding rod 23 will directly abut from the slide groove A21 to the top position of the slide groove C29. Therefore, the degree of squeezing of the rack 18 into the side wall of the inner tube 8 reaches the maximum. At this time, the inner door panel 10 is fully opened and the clamping plate 16 set at the top end of the outer side is squeezed to the bottom end of the sealing plate 24. After the outer door panel 4 is closed, the rotating wheel 11 contacts the abutment rod 19. When the sliding rod 23 slides from the top to the bottom in the slide groove C29 to the surface of the guide plate 30, it is guided by the guide plate 30 and slides into the clamping groove 28 for fixing. Therefore, when the first rotation of the inner tube 8 is started after the outer door panel 4 is closed, the inner door panel 10 is in the open state.

[0070] In order to realize the switching of the track of the slide bar 23 between the slide groove A21, the slide groove B27, the slide groove C29 and the clamping groove 28 in the above-mentioned precautions, a horizontally placed 6-shaped shape is formed between the slide groove A21, the slide groove B27, the slide groove C29 and the clamping groove 28, the slide groove A21 and the slide groove B27 are connected at both ends and the clamping groove 28 is set at the top connection, and the slide groove C29 is connected at the connection between the top of the slide groove A21 and the clamping groove 28 and the guide plate 30 is connected here through the torsion spring shaft 26;

[0071] The depth of the chute A21 at the connection between the chute A21 and the chute B27 is deeper than the depth of the chute B27: so that when the slide bar 23 is located at the connection position between the chute A21 and the chute B27, after the rotating wheel 11 contacts and squeezes the abutment rod 19, the slide bar 23 can slide toward the top along with the chute A21 into the chute C29 or the clamping groove 28, and automatically falls into the chute A21 when the slide bar 23 reaches the bottom position of the chute A21 and the chute B27;

[0072] The depth of the slot 28 and the slot C29 at the connection between the top of the slide slot A21 and the slot 28 and the slide slot C29 is deeper than the depth of the slide slot A21: so that after the slide bar 23 slides to the position of the guide plate 30 set at the top of the slide slot A21, it can directly fall to the bottom of the slide slot C29 and one end of the slot 28. When the inner door panel 10 is in the closed state, the resistance rod 19 slides to the surface of the rotating wheel 11 and separates. At this time, the slide bar 23 will be resisted by the resistance rod 19 and slide from the bottom of the slide slot A21 to the top, and directly fall into the slide slot C29 and the slot 28 for limiting, so that the inner door panel 10 reaches the open state;

[0073] At the same time, the length of the guide plate 30 connected by the torsion spring shaft 26 is adapted to the distance between the interference rod 19 and the rotating wheel 11. When the interference between the rotating wheel 11 and the interference rod 19 reaches the maximum, the slide bar 23 moves the guide plate 30 to rotate and separate from the guide plate 30 to achieve the reset of the guide plate 30. The slide bar 23 can also slide downward and slide along the guide plate 30 into the slot 28 after being separated and reset between the rotating wheel 11 and the interference rod 19.

[0074] At the connection between the top of the slide groove B27 and the slot 28, the depth of the slide groove B27 is deeper than the depth of the slot 28: so that when the inner door panel 10 is in the open state, after the resistance rod 19 contacts the surface of the rotating wheel 11, the slide rod 23 is pushed out from the slot 28 and automatically falls into the slide groove B27, thereby sliding along the slide groove B27 to the bottom end and falling again into the bottom end of the slide groove A21, so that the inner door panel 10 is closed again.

[0075] During use of the device, the inner door panel 10 can be opened while the outer door panel 4 is opened. However, in order to prevent the high-temperature air in the inner tube 8 from being directly discharged and causing harm to the workers, after the outer door panel 4 and the inner door panel 10 are opened, the inner tube 8 is automatically sealed, and the outer door panel 4 is turned over from top to bottom to discharge a small amount of hot air when the outer door panel 4 is opened upward, reducing the harm to the workers, and the inner door panel 10 is set to be intermittently opened and closed with the rotation of the inner tube 8, which is convenient for disassembling the inner tube 8. At the same time, the inner door panel 10 can also be used to scrape and self-clean the surface of the filter plate 13 for screening electronic components and circuit boards arranged at the bottom of the outer cylinder 2. The inner door panel 10 not only plays the role of a guide plate after the circuit board is put in, and the circuit board in the cavity 20 is put into the inner cylinder 8 to disassemble the electronic components, but can also be used as a scraper to clean the surface of the filter plate 13 after the electronic components are disassembled. At the same time, when the circuit board is put in, even if the inner cylinder 8 is in an open state, the inside of the inner cylinder 8 can still be sealed.

[0076] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
