Description

[0002] With the rapid development of the electronics industry and the continuous improvement of environmental awareness, the output of circuit boards is increasing, and the amount of waste circuit boards generated is also relatively large. The recycling of waste circuit boards is very important. The automatic circuit board solder recovery device is a device specially used to recover the solder on the circuit board. It can efficiently separate and recover the solder through automation and mechanization. The recovery of solder is mainly achieved by heating the solder on the circuit board with electric heating, melting the solder, and separating the solder from the circuit board and electronic components.

[0003] The existing circuit board solder recovery devices do technically achieve the initial separation of solder and circuit boards, significantly improving the efficiency of resource recycling. However, a common limitation of these devices is that they often stop at the separation stage and fail to further shape the recycled tin.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the impurities in the tin material are effectively removed by filtering through the filter screen, the third motor drives the half gear to rotate, the half gear is meshed with the third gear for transmission, and the extension shaft and the first cam are driven to rotate. The first cam drives the slider and the limit block to rotate, so that the slider slides along the fixed ring, the spring is stretched, and the limit block slides along the inner wall of the second limit groove, when the limit block slides to the end of the second limit groove, the gap of the first cam coincides with the gap on the second cam, so that the quantitative tin material inside the metering cylinder can be discharged, and the convex teeth on the half gear are meshed and disengaged from the third gear, and under the tension of the spring, the slider slides in the opposite direction along the fixed ring, so that the first cam blocks the gap on the second cam, so that the tin material inside the metering cylinder can be prevented from leaking, and the tin material flowing out of the metering cylinder falls into the top of the tapered hole at the top of the third gear, and is discharged along the tapered hole. This design can further shape the collected tin material, so that the tin material forms tin bars of uniform shape and size, so as to facilitate the later tin material transportation, thereby improving the convenience and efficiency of subsequent tin material reprocessing and purification.

[0021] 2. In the present invention, the first motor is started, and through the transmission of the two first gears, the two output shafts are driven to rotate, thereby driving the multiple crushing wheels to rotate at high speed, and the waste circuit boards are finely crushed, so that the tin materials in the subsequent crushed materials can be fully heated and melted, thereby improving the recovery efficiency of the tin materials.

[0022] 3. In the present invention, the second motor drives the rotating shaft to rotate, and through the second gear transmission, the mounting shaft drives the driving wheel to rotate. When the driving wheel rotates, it squeezes the tooth plate, and the tooth plate vibrates, which drives the feeding plate to shake, and evenly spreads the scraps on the metal mesh belt, which facilitates the uniform distribution of the scraps. At the same time, under the drive of the rotating shaft, the metal mesh belt is driven to rotate and reciprocate through the conveying cylinder, and the metal mesh belt drives the scraps to move, and the metal mesh belt can be positioned through multiple positioning wheels.

[0023] 4. In the present invention, the metal mesh belt drives the scraps to move to a position close to the peak and valley of the first limiting groove. At this time, the scraps on the metal mesh belt are flipped, and the scraps are fully heated during the flipping process. The melted tin material gathers to a lower position along the metal mesh belt, and drips from the metal mesh belt, naturally gathers and falls on the second heating plate, and finally flows into the collection box, which is convenient for the collection of the tin material.

[0071] Vibration feeding: The scraps are transported to the top of the feeding plate 211, and the second motor 221 drives the rotating shaft 208 to rotate, which is then transmitted through the second gear 219, so that the mounting shaft 216 drives the transmission wheel 217 to rotate. When the transmission wheel 217 rotates, it squeezes the tooth plate 215, and the tooth plate 215 vibrates, which in turn drives the feeding plate 211 to shake, and evenly spreads the scraps on the metal mesh belt 209. In this process, the torsion spring 214 ensures that the tooth plate 215 and the transmission wheel 217 are in continuous contact.

[0072] Heating and melting: Driven by the rotating shaft 208, the metal mesh belt 209 is driven to rotate and reciprocate through the conveying cylinder 207. When the metal mesh belt 209 rotates, it drives multiple positioning wheels 205 to rotate, and the scraps are moved by the metal mesh belt 209 and heated by the first heating plate 206, so that the tin in the scraps is quickly melted.

[0073] The metal mesh belt 209 drives the scraps to move toward a position close to the peak and valley 203 of the first limiting groove 202. At this time, the scraps on the metal mesh belt 209 are flipped. The scraps are fully heated during the flipping process. The melted tin gathers toward a lower position along the metal mesh belt 209 and drips from the metal mesh belt 209, naturally gathers and falls onto the second heating plate 210, and finally flows into the collection box 301.

[0074] The scraps after the tin is removed are discharged onto the guide plate 403 through the metal mesh belt 209 , and the scraps are discharged into the waste frame 402 through the guide plate 403 .

[0075] Impurity filtering and collection: Under the continuous heating of the second heating plate 210, the tin material in the collection box 301 remains in liquid state and is filtered through the filter 318 to effectively remove impurities in the tin material.

[0076] Metering and discharge: The third motor 304 drives the half gear 305 to rotate, and the half gear 305 is meshed with the third gear 315 to drive the extension shaft 311 and the first cam 312 to rotate. The first cam 312 drives the slider 313 and the limit block 314 to rotate, so that the slider 313 slides along the fixing ring 309. At this time, the spring 310 is stretched, and the limit block 314 slides along the inner wall of the second limit groove 307. When the limit block 314 slides to the end of the second limit groove 307, the notch of the first cam 312 coincides with the notch on the second cam 317, so that a certain amount of tin material in the metering cylinder 302 can be discharged. After the convex teeth on the half gear 305 are engaged and disengaged from the third gear 315, under the pulling force of the spring 310, the slider 313 slides in the opposite direction along the fixing ring 309, so that the first cam 312 blocks the notch on the second cam 317, so that the tin material inside the metering cylinder 302 can be prevented from leaking. The tin material flowing out of the metering cylinder 302 falls into the top of the tapered hole 316 at the top of the third gear 315, and is discharged along the tapered hole 316.

[0077] Tin material shaping: the fourth motor 405 drives the transmission shaft 406 to rotate intermittently, drives the transmission roller 407 to rotate through the transmission shaft 406, drives the chain belt 408 to rotate reciprocatingly through the transmission roller 407, drives the shaping mold 409 to rotate through the chain belt 408, and moves the shaping mold 409 to the bottom of the metering cylinder 302. At this time, the tin material discharged from the tapered hole 316 is concentrated into the shaping mold 409. When the shaping mold 409 moves, it can wait for the tin material inside the shaping mold 409 to cool and form. When the shaping mold 409 moves to the port facing downward, the shaping tin material inside the shaping mold 409 can be discharged, completing the entire recycling process.

[0078] The automatic circuit board solder recycling device has the advantages of high efficiency, energy saving, precision, and environmental protection. It can recycle solder from waste circuit boards and make positive contributions to resource recycling and environmental protection.
