Description

Technical Field

[0002] A computer is an electronic device that can run according to a predetermined program, and a circuit board is one of the basic components to maintain the normal operation of a computer. It connects related electronic components through circuits composed of precious metals to form reliable electrical connections and pathways. However, for old computers, in order to save natural resources and avoid waste, it is necessary to recycle components such as circuit boards that contain a variety of precious metal materials. A common recycling method is to crush the circuit boards so that the various materials inside are no longer restricted by the outer shell. Further, with the help of air separation, gravity screening, hot melting and other methods, the target materials can be separated and collected from the mixture.

[0003] However, since most of the electronic components on the surface of the circuit board are connected to the circuit board by wave soldering, it is not easy to separate the electronic components from the circuit board under the action of the tin-based alloy. At this time, some reusable electronic components will be crushed along with the circuit board, and the tin-based alloy used for fixing will produce a pungent odor when heated. When it is crushed and hot-melted along with the circuit board, the tin-based alloy may produce a large amount of pungent odor under continuous heating, which is not conducive to environmental protection. At the same time, after hot melting, the tin-based alloy and other precious metals may be mixed with each other, increasing the recycling cost of the tin-based alloy. Summary of the invention

[0018] Working principle: When in use, the waste computer circuit boards are transported to the processing grooves on the surfaces of the limit plates on both sides in turn through the conveyor belt, and then the servo motor is started, so that the driving wheel can drive the transmission wheel to rotate clockwise through the hollow column, and the engagement between the transmission wheel and the driving wheel 1 can make the driving wheel 1 drive the rotating drum and the limit plate to rotate counterclockwise. At this time, under the support of the support cylinder, the processing grooves evenly distributed on the surface of the limit plate can drive the computer circuit board placed inside to rotate. Since there are multiple support frames evenly distributed inside the support cylinder, and there are heating tube groups and scrapers 1 on both sides of the top of the support frame, the tin-based alloy at the bottom of the circuit board can contact the heating tube group in turn through the processing groove when the limit plate rotates, and then the melted tin can be melted through each scraper 1. The tin-based alloy is gradually scraped off from the surface of the circuit board, and the spatial heights of each group of support frames, heating tube groups, and scraper one are successively increased to prevent the subsequent heating tube groups and scraper one from being unable to effectively contact the tin-based alloy. In addition, the liquid tin-based alloy scraped off by scraper one can drip along scraper one into the inside of the support tube under the action of its internal residual heat. At this time, gravity can make the liquid tin-based alloy enter the rotating cylinder through the evenly distributed through grooves, and further drip into the solder box. For the partially cooled and solidified tin-based alloy, it can be scraped off from the inner wall of the support tube by scraper two, and then it can also fall into the solder box through the through groove, so as to achieve the purpose of recycling the tin-based alloy on the surface of the circuit board, avoid the waste of tin-based alloy, and at the same time avoid the mixing of tin-based alloy with other waste materials, reducing the subsequent recycling and purification of tin-based alloy. The workload of the alloy. In addition, since there is a gap on one side of the support cylinders on both sides, the circuit board that has passed through multiple heating tube groups and the scraper plate can fall from the inside of the processing groove to the guide plate due to the loss of support from the support cylinder when it moves to the gap with the limit plate. Further, the circuit board and the electronic components fixed on its surface can slide down to the U-shaped slide plate under the action of gravity, and the driving wheel 2 engaged with it can also transmit power to the connecting plate when the driving wheel rotates. At this time, the arc-shaped inclined blocks evenly distributed on the surface of the connecting plate under the restriction of the limit ring and the limit frame can use their inclined surfaces to push the push rod up, thereby making the U-shaped support plate and the U-shaped slide plate move accordingly, and as the push rod falls from the highest point on the surface of the arc-shaped inclined block to the lowest point on the surface of the next arc-shaped inclined block, the U-shaped support plate and the U-shaped slide plate can also Under the guidance of the L-shaped support plate, it falls rapidly, so the purpose of separating the electronic components on the surface of the circuit board from the circuit board can be achieved by utilizing the vibration generated after the U-shaped slide board falls, and the fallen electronic components can be intercepted through multiple inclined grooves while the circuit board continues to slide forward along the U-shaped slide board, and further, with the cooperation of the inclined surfaces inside the inclined grooves, the intercepted electronic components can slide to both sides to the collection box by themselves, thereby achieving the purpose of actively separating the circuit board and the electronic components, avoiding that some high-value electronic components that can still be used are crushed together with the circuit board, and each electronic component can be collected by subsequent air separation, gravity screening, etc., reducing the difficulty of recycling, and when the transmission wheel rotates continuously, the rotating rod connected to it can transmit power to the impeller, and then suction can be generated by the rotation of the impeller.In cooperation with the exhaust groove 1, the hollow cylinder and the air guide pipe, the hot air generated when the heating tube group is heated is continuously sucked into the inside of the support tube, so as to prevent a large amount of liquid tin-based alloy from solidifying due to the low temperature inside the support tube, thereby reducing the resistance suffered by the scraper 2 and the rotating drum when they rotate. The hot air can also enter the lower part of the hollow column through the exhaust groove 1, the hollow cylinder and the air guide pipe and contact with the activated carbon on the surface of the disc. Therefore, the pungent smell generated when some heating tube groups heat the tin-based alloy can also contact with the activated carbon with the hot air. At this time, the activated carbon can be used to adsorb and purify the pungent smell to prevent the pungent smell from accumulating in large quantities and posing a threat to the health of nearby workers. The vertical plate can be used to block the circuit board after the electronic components are separated. When the circuit When the boards gather to a certain extent, the thrust exerted on the trapezoidal block 2 can act on the trapezoidal block 1 through the inclined surface between the trapezoidal block 2 and the trapezoidal block 1, and further, the vertical plate can move vertically upward along the U-shaped slide plate as the trapezoidal block 1 overcomes the resistance generated by the counterweight block, and the circuit boards blocked by the vertical plate can pass over the vertical plate and enter the subsequent crushing and recycling link. At the same time, since the force exerted on the trapezoidal block 2 will decrease after the circuit boards are discharged in large quantities along the U-shaped slide plate, the counterweight block can drive the vertical plate to return to the initial position to achieve the purpose of quantitatively releasing the circuit boards, and prevent the circuit boards from entering the crushing step excessively at a single time, which affects the crushing effect. In summary, the cooperation between various mechanisms can improve the recycling efficiency of waste circuit boards, save resources, and reduce the harm to the outside world during recycling.

[0019] The present invention provides an automated processing device for waste computer circuit board parts.

[0020] Beneficial effects:

[0021] 1. The present invention can heat the tin-based alloy on the surface of the circuit board through the setting of the heating mechanism, and then the tin-based alloy can be stripped and collected from the surface of the waste circuit board to avoid waste. It can further ensure that the tin-based alloy can be reused after being processed in a small number of processes with relatively high purity, thereby reducing the recycling cost. In addition, the setting of the separation mechanism can actively separate the electronic components that have lost their fixation from the surface of the circuit board after the tin-based alloy is stripped, and the subsequent air selection, gravity screening, etc. can be used to classify and collect the various electronic components to prevent the mixing of various material components after concentrated crushing, which increases the difficulty of separation. At the same time, some high-value and still usable electronic components can also be selected and reused to avoid their crushing and waste.

[0022] 2. The present invention can absorb the hot air generated when the heating mechanism heats the tin-based alloy into the support tube through the setting of the suction mechanism, so as to avoid a large amount of liquid tin-based alloy from cooling and solidifying during the transfer process due to the low temperature inside the support tube, thereby reducing the resistance encountered by the rotating drum and the scraper when they rotate. In addition, the irritating odor generated when the tin-based alloy is partially heated by the flow of hot air can also flow along with it, and further can be brought into contact with the activated carbon to achieve the purpose of adsorption and purification of the air, prevent a large amount of irritating odor from diffusing into the air and polluting the surrounding environment, and achieve the effect of protecting nearby workers.

[0023] 3. The present invention can quantitatively release the processed circuit boards within a certain range through the setting of the quantitative transfer mechanism, so as to prevent the circuit boards from being transferred to the subsequent crushing step in a concentrated manner due to excessive quantity, which may affect the crushing effect and thus avoid affecting the subsequent recycling efficiency.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please see attached Figure 1 , Attachment Figure 2 , Attachment Figure 5 , Attachment Figure 6 and attached Fig. 9 The embodiment of the present invention provides an automated processing device for waste computer circuit board parts, comprising a base 1, which is used as a basic bearing component to provide a basic installation plane; a heating mechanism 2, which is arranged at the rear of the top of the base 1, and is used to heat and scrape the tin-based alloy on the surface of the circuit board;

[0037] The heating mechanism 2 includes a servo motor 201, the top of the servo motor 201 is fixedly connected to the rear of the bottom of the base 1, the output end of the servo motor 201 passes through the base 1 and is fixedly connected to a driving wheel 202, the top of the driving wheel 202 is fixedly connected to a hollow column 203, the top of the hollow column 203 is fixedly connected to a transmission wheel 204, both sides of the rear of the transmission wheel 204 are meshed with driving wheels 1 205, the middle of the driving wheels 1 205 on both sides are fixedly connected to a rotating drum 206, the tops of the rotating drums 206 on both sides are fixedly connected to a limiting disk 207, the outer sides of the limiting disks 207 on both sides are provided with a plurality of processing grooves 208, and the two limiting disks 207 on both sides are provided with a plurality of processing grooves 208. The lower outer part of the side rotating cylinder 206 is rotatably connected to the support cylinder 209, the upper inner part of the support cylinders 209 on both sides is fixedly connected to a plurality of support frames 210, one side of the top of the plurality of support frames 210 is fixedly connected to a heating tube group 211, the other side of the top of the plurality of support frames 210 is fixedly connected to a scraper 212, the outer bottom ends of the limit plates 207 on both sides are rotatably connected to the top of the support cylinder 209, the side of the support cylinders 209 on both sides are fixedly connected to a guide plate 213, the lower part of the rotating cylinders 206 on both sides is provided with a plurality of through grooves 214, and solder boxes 215 are fixedly connected to both sides of the rear part of the top of the base 1.

[0038] The driving wheel 202 can drive the hollow column 203 and the transmission wheel 204 to rotate clockwise by the servo motor 201, and then the engagement between the transmission wheel 204 and the driving wheel 205 can be used to drive the limiting plate 207 to rotate counterclockwise. At the same time, since a plurality of U-shaped processing grooves 208 are evenly distributed on the surface of the limiting plate 207, and there are protruding parts on both sides of the processing groove 208, the top surface of the supporting cylinder 209 and the protruding parts inside the processing groove 208 can be used to The old circuit board is supported so that the circuit board can be placed in the processing tank 208 under the action of the external conveyor belt and the robot arm and can rotate synchronously with the limit plate 207. Furthermore, the heating tube group 211 and the scraper 212 can be supported by the evenly distributed support frame 210, and each group of support frame 210, heating tube group 211, and scraper 212 is slightly elevated in space. Therefore, as the limit plate 207 rotates, the circuit board can contact each heating tube group 211 in turn, so as to be melted layer by layer. The solidified tin-based alloy on its bottom surface can be gradually scraped off the melted tin-based alloy from the bottom surface of the circuit board in cooperation with each scraper 212. The scraped liquid tin-based alloy can drip from the surface of the scraper 212 to the inside of the support tube 209 under the action of the internal residual heat, and then can approach the evenly distributed through grooves 214 along the support tube 209, and enter the inside of the rotating drum 206 through the through grooves 214 during the rotation of the rotating drum 206, until it falls into the solder box 215, thereby achieving the purpose of effectively recovering the tin-based alloy, avoiding the tin-based alloy from mixing with various materials after the circuit board is crushed, thereby reducing the separation steps and recycling costs of the tin-based alloy, and also avoiding the tin-based alloy from generating excessive pungent odor during subsequent hot melting. After the circuit board is processed by multiple heating tube groups 211 and scraper 212, as it moves to the notch on the side close to the support tube 209, since the support tube 209 no longer supports the circuit board, the circuit board can fall into the guide plate 213 under the action of gravity to actively leave the processing tank 208.

[0039] Please see attached Figure 4 and attached Figure 5 The bottom end of the driving wheel 202 is rotatably connected to the rear top of the base 1, and arc-shaped baffles 216 are fixedly connected to the outer sides of the support cylinders 209 on both sides. The bottom ends of the arc-shaped baffles 216 on both sides are fixedly connected to the rear top of the base 1. Support rings 217 are fixedly connected inside the arc-shaped baffles 216 on both sides. The top ends of the support rings 217 on both sides are rotatably connected to the outer side of the bottom end of the driving wheel 1 205. The solder boxes 215 on both sides are directly facing the rotating cylinder 206. A plurality of scraper plates 218 are fixedly connected to the upper outer sides of the rotating cylinders 206 on both sides. The plurality of scraper plates 218 are slidably connected to the middle part of the support cylinder 209 away from the rotating cylinder 206.

[0040] The base 1 can be used to limit the driving wheel 202 to prevent it from deviating from the predetermined position, and the arc-shaped baffle 216 can be used to fix the support cylinder 209 and prevent the driving wheel 205 from contacting foreign objects, thereby preventing the circuit board from actively detaching from the processing groove 208 after the support cylinder 209 rotates with the rotating cylinder 206. At the same time, the driving wheel 205 can be fixed by the support ring 217 to ensure that the driving wheel 205 and the transmission wheel 204 always maintain effective engagement. In addition, since the solder box 215 is facing the rotating cylinder 206, it can be ensured that the tin-based alloy can fall into the solder box 215 and be collected. The evenly distributed scraper 218 can be used to scrape off the tin-based alloy that may solidify on the inner wall of the support cylinder 209 when the rotating cylinder 206 rotates to prevent it from being recycled.

[0041] Please see attached Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 7 , a separation mechanism 3, which is arranged at the front of the top of the base 1 and is used to separate the circuit board and the electronic components on its surface;

[0042] The separation mechanism 3 includes a driving wheel 201, the rear portion of which is meshed with the front portion of the driving wheel 202, a connecting disk 302 is fixedly connected to the top of the driving wheel 201, a plurality of arc-shaped inclined blocks 303 are fixedly connected to the top of the connecting disk 302, a push rod 304 is slidably connected to the top of the plurality of arc-shaped inclined blocks 303, a U-shaped support plate 305 is fixedly connected to the top of the push rod 304, a U-shaped support plate 305 is fixedly connected to the top of the U-shaped slide plate 306, and a plurality of inclined grooves 307 are provided in the middle of the bottom end of the U-shaped slide plate 306.

[0043] The power output by the servo motor 201 can be transmitted to the connecting disk 302 through the meshing between the driving wheel 201 and the driving wheel 202, so that the arc-shaped inclined blocks 303 evenly distributed on the surface thereof can rotate counterclockwise. At this time, the corresponding push rods 304 can be driven to move upward through the inclination of the arc-shaped inclined blocks 303 themselves. As the driving wheel 201 and the connecting disk 302 continue to rotate, when the push rods 304 fall from the highest point on the surface of the previous arc-shaped inclined block 303 to the lowest point on the surface of the rear arc-shaped inclined block 303, the hollow U-shaped supporting plate 305 connected to the evenly distributed push rods 304 can fall accordingly under the action of gravity, so as to achieve the purpose of driving the U-shaped slide plate 306 to move back and forth. At this time, the circuit board that slides from the guide plate 213 to the U-shaped slide plate 306 can lose its position due to the vibration during the movement of the U-shaped slide plate 306. The electronic components fixed by the tin-based alloy are separated from the circuit board. Furthermore, since there are multiple inclined grooves 307 inside the U-shaped slide 306 and the width of the inclined grooves 307 is limited, only the electronic components can be intercepted, while the circuit board can cross the inclined grooves 307 and continue to move forward along the U-shaped slide 306 under continuous vibration. In summary, the purpose of actively separating the circuit board and the electronic components can be achieved, and the electronic components can be prevented from entering the subsequent crushing step with the circuit board, resulting in some normally usable and high-value electronic components being wasted. In addition, since the inclined groove 307 is truncated cone-shaped, the electronic components can slide to both sides along the slope of its inner surface to prevent the electronic components from gathering in large quantities and filling up the inclined groove 307. The various separated electronic components can be collected collectively according to their types after subsequent air separation, gravity screening and other steps to avoid mixing with each other and increasing the difficulty of recycling.

[0044] Please see attached Figure 2 , Attachment Figure 3 and attached Figure 7 The bottom end of the second driving wheel 301 is rotatably connected to the front top of the base 1, and the outer sides of multiple push rods 304 are slidably connected to the limiting ring 308, and the side close to the limiting ring 308 is fixedly connected to the limiting frame 309, and the bottom end of the limiting frame 309 is fixedly connected to the front top of the base 1. A plurality of protrusions 310 are fixedly connected to the bottom end of the U-shaped slide plate 306, and both sides of the U-shaped slide plate 306 are slidably connected to L-shaped support plates 311, and the bottom ends of the L-shaped support plates 311 on both sides are fixedly connected to both sides of the front top of the base 1, and a collection box 312 is provided on the side away from the top of the L-shaped support plates 311 on both sides.

[0045] The base 1 can be used to limit the driving wheel 201, so that the driving wheel 201 can maintain effective engagement with the active wheel 202. The limiting frame 309 and the evenly distributed limiting rings 308 can be used to guide each push rod 304 with the cooperation of the base 1 to prevent them from horizontal displacement and affecting the normal use of the U-shaped support plate 305 and the U-shaped slide plate 306. At the same time, the multiple protrusions 310 can extend the time for the circuit board to pass through the area where the inclined groove 307 is located to a certain extent, preventing the circuit board from sliding too fast and causing some electronic components to not fall off the surface of the circuit board in time when the U-shaped slide plate 306 vibrates. In addition, the L-shaped support plate 311 can be used to guide the movement direction of the U-shaped slide plate 306 to prevent the U-shaped slide plate 306 and the U-shaped support plate 305 from deviating from the predetermined movement trajectory. Further, the various electronic components that slide off the U-shaped slide plate 306 from the inclined groove 307 can be collected by the collection box 312.

[0046] Please see attached Figure 4 and attached Figure 8 , an air suction mechanism 4, which is arranged inside the heating mechanism 2 and is used to guide the hot air and treat the irritating gas generated when the tin-based alloy is melted;

[0047] The air suction mechanism 4 includes a rotating rod 401, the top of which is fixedly connected to the middle of the bottom end of the transmission wheel 204, the outer side of the rotating rod 401 is fixedly connected to an impeller 402, a plurality of exhaust grooves 403 are provided inside the transmission wheel 204, the top of the transmission wheel 204 is rotatably connected to a hollow cylinder 404, both sides of the rear end of the hollow cylinder 404 are fixedly connected to air guide tubes 405, the ends of the air guide tubes 405 away from the hollow cylinder 404 are fixedly connected to the front end of the support cylinder 209, the rear end of the hollow cylinder 404 is fixedly connected to a fixing plate 406, and both sides of the rear end of the fixing plate 406 are fixedly connected to the front end of the arc-shaped baffle 216.

[0048] The impeller 402 can be rotated with the transmission wheel 204 through the rotating rod 401, and suction can be generated through the rotation of the impeller 402, so that the suction can be transmitted to the inside of the support tube 209 under the action of the hollow tube 404, the air duct 405 and the evenly distributed exhaust grooves 403, and the high-temperature air near the heating tube group 211 can be further moved to the inside of the support tube 209 to ensure that the internal temperature of the support tube 209 is relatively high, and to prevent a large amount of liquid tin-based alloy from cooling and solidifying due to rapid heat loss when moving along the inner wall of the support tube 209, thereby achieving the purpose of reducing the resistance encountered by the scraper 218 and the rotating drum 206 during rotation, and making the rotating drum 206, the limit plate 207, etc. more stable during rotation. In addition, the hollow tube 404 can be connected to the arc baffle 216 by using the fixing plate 406, so as to achieve the effect of supporting the hollow tube 404, and to prevent the hollow tube 404 from rotating with the transmission wheel 204 and causing the air duct 405 to be subjected to shear force.

[0049] Please see attached Figure 3 and attached Figure 8 A disc 407 is fixedly connected to the middle of the hollow column 203, an exhaust hole 408 is opened in the middle of the disc 407, a separation cylinder 409 is fixedly connected to the top of the disc 407, a plurality of through holes 410 are opened at the bottom of the separation cylinder 409, a partition plate 411 is fixedly connected inside the separation cylinder 409, and the bottom end of the partition plate 411 is fixedly connected to the top of the disc 407, and a plurality of exhaust grooves 412 are opened at the lower part of the hollow column 203.

[0050] The activated carbon can be blocked on its upper surface by the disc 407, and the evenly distributed through holes 410 can allow the air sucked into the hollow column 203 by the impeller 402 to pass through the activated carbon and enter the internal space of the separation tube 409, and the height of the partition 411 can block the activated carbon while allowing the air to leave through the top hole thereof, so as to prevent the activated carbon from entering the separation tube 409 and then falling into the area below the disc 407 through the exhaust hole 408. Similarly, for some irritating gases generated when the heating tube group 211 contacts the tin-based alloy, they can also contact the activated carbon along the support tube 209, the air guide tube 405, the hollow tube 404, and the exhaust groove 1 403, and after being adsorbed and purified by the activated carbon, they can be discharged from the hollow column 203 along the through holes 410, the top holes of the partition 411, the exhaust holes 408 and the exhaust groove 2 412, so as to reduce the impact of the irritating gases on the environment, thereby achieving the purpose of protecting nearby workers.

[0051] Please see attached Figure 4 and attached Fig.10 , a quantitative transfer mechanism 5, which is arranged in the front part of the separation mechanism 3 and is used for quantitatively transferring the processed circuit boards;

[0052] The quantitative transfer mechanism 5 includes a vertical plate 501, and both sides of the vertical plate 501 are slidably connected to the front parts of the two sides of the U-shaped slide 306, and both sides of the rear end of the vertical plate 501 are fixedly connected with trapezoidal blocks 1 502, and the rear ends of the trapezoidal blocks 1 502 on both sides are slidably connected with trapezoidal blocks 2 503, and the front end of the vertical plate 501 is fixedly connected with a counterweight block 504, and the bottom ends of the trapezoidal blocks 2 503 on both sides are slidably connected to both sides of the bottom end of the U-shaped slide 306.

[0053] The U-shaped slide plate 306 can be used to limit the movement direction of the vertical plate 501, and the counterweight block 504 can be used to increase the deadweight of the vertical plate 501. After the circuit board passes through the area where the inclined groove 307 is located, it can contact the vertical plate 501 and the trapezoidal block 2 503. As the circuit boards continue to gather, the thrust applied by the trapezoidal block 2 503 to the trapezoidal block 1 502 through the inclined surface also continues to increase, and the vertical plate 501 can further overcome the gravity of the counterweight block 504 and gradually rise with the trapezoidal block 1 502. At this time, a certain number of circuit boards can quickly pass through the area where the vertical plate 501 is located and enter the next crushing step. When the thrust applied to the trapezoidal block 2 503 is significantly reduced, the vertical plate 501 can return by itself under the action of gravity, so as to achieve the purpose of quantitatively releasing the processed circuit boards and prevent excessive circuit boards from entering the subsequent crushing steps and affecting the crushing effect.
