Description

Technical Field

[0001] This invention relates to the field of PCB board disassembly technology, specifically to a PCB board production desoldering equipment. Background Technology

[0002] PCB (Printed Circuit Board) is a provider of electrical connections for electronic components. It typically uses an insulating board as a substrate, cut into fixed sizes, and enables the interconnection between electronic components.

[0003] After recycling, discarded PCB circuit boards usually need to undergo desoldering to disassemble the electronic components connected to them. Traditionally, this is done manually, which is time-consuming and labor-intensive. In addition, in order to prevent the gas generated during desoldering from polluting the environment, the process is usually carried out in a sealed box. However, since PCB circuit boards vary in size, while the size of the sealed box is fixed, it cannot accommodate PCB circuit boards larger than that size for desoldering, thus reducing the practicality of the device.

The fifth guide rod 413 is fixedly installed inside the lifting frame 411. A third drive motor 416 is provided on the outside of the movable part 415. The output end of the third drive motor 416 is fixedly connected to the first double-headed electric cylinder 417 through a kit. A first locking block 418 is fixedly installed on both output ends of the first double-headed electric cylinder 417.

[0027] Please refer to Figure 9 , Figure 10 and Figure 11As shown, the feeding mechanism 4 also includes a sealing plate 419. A second slot 420, adapted to the first locking block 418, is provided on the outer side of the sealing plate 419. A second double-headed electric cylinder 421 is rotatably connected to the top of the sealing plate 419. Both output ends of the second double-headed electric cylinder 421 are fixedly connected to the second locking block 422. A first slot 106, adapted to the second locking block 422, is provided on the top of the sealing frame 105. A motor is provided on the top of the sealing plate 419. A first drive gear 423 is fixedly installed on the output end of the motor. A gear meshing with the first drive gear 423 is provided on the outer side of the second double-headed electric cylinder 421. The first driven tooth and the inner side of the sealing plate 419 are rotatably connected to the first threaded rod 424. Both ends of the outer surface of the first threaded rod 424 are threadedly connected to the frame 427. The threads at both ends of the first threaded rod 424 are in opposite directions. The inner side of the sealing plate 419 is also provided with a first servo motor 426 that drives the first threaded rod 424 to rotate. The inner side of the sealing plate 419 is fixedly connected to the first fixed rod 425. The frame 427 is slidably connected to the first fixed rod 425. The top of the frame 427 is provided with a fourth electric push rod 428. The output end of the fourth electric push rod 428 is fixedly connected to the pressure block 429.

[0028] Please refer to Figure 5 and Figure 6 As shown, a first electric push rod 112 is provided on the top of the desoldering box 108. The output end of the first electric push rod 112 is fixedly connected to the mounting block 113. A second electric push rod 114 is fixedly connected to the top of the mounting block 113. The output end of the second electric push rod 114 is fixedly connected to the abutment 115.

[0029] Those skilled in the art will understand that the output of the third stepper motor 404 drives the third lead screw 402 to rotate, causing the movable plate 405 to reciprocate horizontally, thereby driving the closing plate 419 to reciprocate horizontally; the output of the fourth stepper motor 410 drives the fourth lead screw 408 to rotate, causing the lifting frame 411 to reciprocate up and down, thereby driving the closing plate 419 to reciprocate up and down; and the output of the fifth stepper motor 414 drives the fifth lead screw 412 to rotate, causing the movable part 415 to reciprocate back and forth, thereby driving the closing plate 419 to reciprocate back and forth. In summary, the closing plate 419 can move in three directions: horizontal, longitudinal, and vertical. Furthermore, by controlling the synchronous extension or retraction of the two output ends of the first double-headed electric cylinder 417, the two sets of first locking blocks 418 are driven to move away from or closer to each other. When the two sets of first locking blocks 418 are close to each other, both sets of first locking blocks 418 are locked inside the second locking slot 420, thereby connecting the sealing plate 419 to the output end of the third drive motor 416, and vice versa, disconnecting it. The output end of the motor drives the first drive gear 423 to rotate, so that the first driven gear and the second double-headed electric cylinder 421 are integrated. The rotation allows the two sets of second locking blocks 422 to remain in a horizontal or vertical state. Similarly, when the two sets of second locking blocks 422 are in a horizontal state, the synchronous extension or retraction of the two output ends of the second double-headed electric cylinder 421 is controlled to drive the two sets of second locking blocks 422 to move away from or towards each other. When the two sets of second locking blocks 422 are close to each other, they can be locked in the first locking slot 106, thus connecting the closed frame 105 to the side of the closed plate 419. Conversely, the connection is released when they move away from each other. Furthermore, the output end of the first servo motor 426 drives the first threaded rod 424 to rotate, causing the two sets of frames 427 to move closer or further apart, changing the distance between the two sets of frames 427 so that the distance matches the width of the PCB board. By controlling the extension of the output end of the fourth electric push rod 428, the pressure block 429 is driven to move downward, thereby pressing the PCB board.

[0030] Example 5 Please refer to Figure 12 As shown, the turning mechanism 5 includes a rotating rod 501 rotatably connected to the top of the body 1. A top frame 504 is welded to the top of the rotating rod 501. A second servo motor 507 is provided on the outer side of the top frame 504. The output end of the second servo motor 507 extends into the top frame 504 and is fixedly connected to a second threaded rod 505. The threads at both ends of the second threaded rod 505 have opposite directions of rotation. A second fixed rod 506 is also welded inside the top frame 504. Two sets of clamping members 508 are slidably connected to the second fixed rod 506. The two sets of clamping members 508 are respectively threaded to the two ends of the outer surface of the second threaded rod 505. A fourth drive motor 502 is also installed on the top of the body 1. The output end of the fourth drive motor 502 is fixedly connected to a second drive tooth 503. A second driven tooth that meshes with the second drive tooth 503 is fixedly installed on the bottom of the outer wall of the rotating rod 501.

[0031] Those skilled in the art will understand that the output of the second servo motor 507 drives the second threaded rod 505 to rotate, causing the two sets of clamping members 508 to move closer or further apart; and the output of the fourth drive motor 502 drives the second drive tooth 503 to rotate, causing the second driven tooth and the rotating rod 501 to rotate as a whole, thereby driving the top frame 504 to rotate.

[0032] Example 6 Please refer to Figure 3 As shown, the pushing mechanism 6 includes a sixth lead screw 601, a sixth guide rod 602, an L-shaped part 604, and a pushing part 606. The sixth lead screw 601 is rotatably connected to the rear top of the machine body 1. The sixth guide rod 602 is welded to the rear top of the machine body 1. The vertical plate of the L-shaped part 604 is threadedly connected to the sixth lead screw 601. The vertical plate of the L-shaped part 604 is slidably connected to the sixth guide rod 602. A sixth stepper motor 603 that drives the sixth lead screw 601 to rotate is also installed on the rear top of the machine body 1. A fifth electric push rod 605 is installed on the top of the horizontal plate of the L-shaped part 604. The top of the pushing part 606 is fixedly connected to the output end of the fifth electric push rod 605. A component collection frame is provided on the left side of the collection box 102.

[0033] Those skilled in the art will understand that by extending or retracting the output end of the fifth electric push rod 605, the pusher 606 is driven to move downward or upward, and the pusher 606 can fit against the top wall of the machine body 1 when it moves downward; and by driving the sixth lead screw 601 to rotate through the output end of the sixth stepper motor 603, the L-shaped part 604 moves horizontally back and forth, thereby driving the pusher 606 to move horizontally back and forth.

[0034] To clearly describe the working principle of this invention, we will use... Figure 1 The description refers to the directional perspective, specifically the "front, back, left, and right sides" mentioned below, as follows: S1. Conveyor 107 transports the PCB circuit board to be desoldered. If the length of the PCB circuit board is greater than the width of the desoldering box 108, it means that the desoldering box 108 cannot be directly used to desolder the PCB circuit board of this specification. It is necessary to install a matching closed frame 105. Then, the output end of the motor drives the first drive tooth 423 to rotate, which drives the first driven tooth and the second double-headed electric cylinder 421 to rotate as a whole, so that the two sets of second clamping blocks 422 keep in a horizontal state. Then, at the output end of the third stepper motor 404, the output end of the fourth stepper motor 410 and the first stepper motor 425, the first drive tooth 423 rotates, which drives the first driven tooth and the second double-headed electric cylinder 421 to rotate as a whole, so that the two sets of second clamping blocks 422 keep in a horizontal state. With the cooperation of the output end of the five-step motor 414, the closing plate 419 moves and adjusts in three directions: horizontal, vertical and vertical, driving the closing plate 419 to the position of the corresponding closing frame 105 in the frame 104. Then, the two output ends of the second double-headed electric cylinder 421 extend and retract synchronously, so that the two sets of second locking blocks 422 are locked in the first locking slot 106 on the closing frame 105, realizing the connection of the closing frame 105 to the left side of the closing plate 419. The sealing ring and sealing groove structure are provided at the contact point between the closing plate 419 and the closing frame 105. S2. Then, with the combined action of the output ends of the third stepper motor 404, the second drive motor 406, the fourth stepper motor 410, and the fifth stepper motor 414, the sealing plate 419 and the sealing frame 105 are aligned with the front side and directly facing the back end of the conveyor 107. The conveyor 107 transfers the last PCB board to be desoldered to the sealing frame 105. Then, the output end of the first servo motor 426 drives the first threaded rod 424 to rotate, so that the spacing between the two sets of frames 427 is adapted to the width of the PCB board. By controlling the extension of the output end of the fourth electric push rod 428, the pressure block 429 is driven to move downward, thereby pressing and fixing the PCB board. S3. Then, with the combined action of the output terminals of the third stepper motor 404, the second drive motor 406, the fourth stepper motor 410, and the fifth stepper motor 414, the sealing plate 419, the sealing frame 105, and the PCB board in the clamping state are adjusted to move as a whole, inserting the PCB board into the desoldering box 108. At this time, the left side of the sealing frame 105 is attached to the right side of the desoldering box 108, and a sealing ring and sealing groove structure are provided at the attachment point, thereby preventing the gas generated during subsequent desoldering from leaking into the external environment. S4. Then, the output end of the second stepper motor 303 drives the second lead screw 301 to rotate, causing the nozzle 304 to reciprocate horizontally left and right, spraying desoldering liquid onto the top of the PCB board located in the desoldering box 108. After a certain time threshold, by controlling the extension of the output end of the third electric push rod 306, the pressure piece 307 moves downward, pressing the left end of the PCB board downward. Then, the output end of the third electric push rod 306 immediately retracts, causing the PCB board to vibrate under its own elasticity, throwing out the electronic components on the area sprayed with desoldering liquid. Some electronic components land on the top of the filter plate 103, and some electronic components may fall into the closed frame 105 during the ejection process, preventing them from falling down. Then, with the cooperation of the output ends of the first electric push rod 112 and the second electric push rod 114, the abutment piece 115 moves to the right side of the closed plate 419. Then, the output end of the first electric push rod 112 immediately retracts, causing the abutment piece 115 to be stuck on the outside of the closed plate 419 and hug the closed plate 419 to the left. The connection between the sealing plate 419 and the output end of the third drive motor 416 is disconnected. Then, the output ends of both sets of tilting cylinders 111 extend, causing both sets of sliding plates 110 to extend and fit together. A sealing ring and sealing groove structure are also provided at the fitting point. Next, with the cooperation of the output ends of the first stepper motor 204 and the first drive motor 206, the desoldering box 108 moves upward and rotates and tilts, causing the electronic components inside the sealing frame 105 to fall down. Afterward, the desoldering box 108 returns to the top of the collection box 102. The bonding area is also equipped with a sealing ring and sealing groove structure. The output ends of the two sets of inclined cylinders 111 are reset, causing the electronic components to fall to the top of the filter plate 103. The desoldering box 108 is also equipped with an exhaust gas treatment device (not shown in the figure) to treat the exhaust gas during the desoldering process. Then, the desoldering box 108 moves upward and the pushing mechanism 6 causes the pushing part 606 to bond with the top of the filter plate 103 and move to the left, pushing the electronic components that fall on the top of the filter plate 103 into the component collection frame for collection. S5. After that, the PCB board is moved to the outside of the desoldering box 108, and the output of the third drive motor 416 drives the PCB board to flip so that the side originally located on the bottom side flips up and re-enters the desoldering box 108, and repeats the above steps to desolder and disassemble electronic components. S6. With the combined action of the output terminals of the third stepper motor 404, the second drive motor 406, the fourth stepper motor 410, and the fifth stepper motor 414, the sealing plate 419, the sealing frame 105, and the PCB board in the clamping state move together to the turning mechanism 5. The two sets of clamping parts 508 come close to each other to clamp the PCB board. Then, the output terminal of the fourth drive motor 502 drives the second drive tooth 503 to rotate, causing the second driven tooth and the rotating rod 501 to rotate together, thereby realizing the rotation and turning of the PCB board. Then, the right side of the PCB board after turning is fixed back in the sealing frame 105. The above steps are repeated to perform the desoldering operation. Then, the output terminal of the third drive motor 416 drives the PCB board to flip. The above steps are repeated to perform desoldering and disassembly of electronic components. Thus, the PCB board can be desoldered and electronic components can be disassembled on both sides, which meets the needs of the staff. S7. If the desoldering box 108 can be directly used to desolder the PCB circuit board on the conveyor 107, the first drive tooth 423 is driven to rotate directly through the output end of the motor, which drives the first driven tooth and the second double-headed electric cylinder 421 to rotate as a whole. This keeps the two sets of second clamping blocks 422 in a vertical state and presses them down through the pressure block 429 to fix the PCB circuit board on the closed plate 419. Then, the PCB circuit board directly enters the desoldering box 108 for desoldering. The output end of the third drive motor 416 drives the PCB board to flip, so that the PCB board can be desoldered on both sides and the electronic components can be disassembled, which improves the practicality of the device.
