Description

Technical Field

[0001] The present invention relates to the technical field of PCB boards, in particular to a circuit board transport structure of a PCB board cutting and edge grinding machine. Background Art

[0002] Printed circuit boards, also known as printed circuit boards, are providers of electrical connections for electronic components. Printed circuit boards are often referred to as "PCBs" rather than "PCB boards." The design of printed circuit boards is mainly layout design. The main advantage of using circuit boards is that they greatly reduce wiring and assembly errors, and improve the level of automation and production labor efficiency.

[0003] A Chinese patent discloses a conveying mechanism for a fully automatic board collecting machine, with patent number 201210581526.4. In this patent, a roller structure is used for conveying, which not only ensures smooth transmission but also greatly ensures the cleanliness of the board surface. Furthermore, the overall structure of the machine is compact, saving factory floor space. The conveying motor of the conveying structure of the present invention adopts a special industrial motor with a reducer. The speed range of the conveying motor is 0.5 to 6 m / min and can be controlled in forward and reverse directions. The present invention can meet the production efficiency requirement of 12 pcs / min PCBs. It is highly automated and uses professional motion control technology. The machine runs fast and smoothly, and the movements are accurate and reliable. The PCB can be freely switched between manual and automatic modes during conveying. The entire machine operates with low noise and automatically enters energy-saving mode when not in operation for a long time, making it environmentally friendly.

[0004] However, in this patent, only one side of the PCB board can be polished during the polishing and transportation process. The PCB board needs to be polished and transported multiple times during the polishing process, which affects the processing efficiency of the PCB board. However, the existing solution is usually to manually place the PCB board back on the conveyor and use the polisher on the conveyor to polish it again. This solution obviously cannot solve the problem and will also increase the workload of the operator and reduce work efficiency.

The movement of the movable rod 201 is consistent with the transmission speed of the conveying device. The four sides of the PCB board can be polished before the movable rod 201 moves to the position of the fixed plate 401, thereby achieving the purpose of polishing the PCB board during the conveying process. At the same time, the four sides of the PCB board can also be polished. The operator is more convenient in the process of conveying and polishing the PCB board. The operator does not need to manually rework the four sides to polish them separately, which reduces the operator's workload.

[0043] The specific implementation of this embodiment is as follows: when polishing the PCB board during transportation, the user places the PCB board on the conveying device, and then the user starts the conveying device to convey the PCB board. At this time, the user uses an external control switch and power supply to start the third motor 8. The start of the third motor 8 drives the threaded rod 9 to rotate, and the threaded rod 9 rotates through the bearing 11. The rotation of the threaded rod 9 drives the threaded sleeve 10 to move. The movement of the threaded sleeve 10 drives the connecting block 5 to move. The movement of the connecting block 5 drives the movable rod 201 to move. The movement of the movable rod 201 drives the slide 202 to move. The movement of the slide 202 drives the card plate 203 to move, so that the card plate 203 moves to the top of the PCB board. At this time, the user uses the external control switch and power supply to start the first electric telescopic rod 14. The start of the first electric telescopic rod 14 drives the positioning rod 15 to move. The movement of the positioning rod 15 drives the slide plate 202 to move. The movement of the slide plate 202 drives the card plate 203 to move, so that the card plate 203 covers the surface of the PCB board. At this time, the user uses the external control switch and power supply to start the second electric telescopic rod 13. The movement of the second electric telescopic rod 13 drives the positioning plate 21 to move. The movement of the positioning plate 21 drives the adaptive rubber pad 22 to move, so that the adaptive rubber pad 22 pushes the PCB board to contact the polishing belt 208, so that the PCB board can be positioned so that it will not deflect ... The control switch starts the first motor 205. The start of the first motor 205 drives the first transmission wheel 206 to rotate. The rotation of the first transmission wheel 206 drives the grinding belt 208 to rotate. The rotation of the grinding belt 208 drives the second transmission wheel 207 to rotate, so that the second transmission wheel 207 rotates through the rotating shaft 209, thereby grinding one side of the PCB board. After grinding one side of the PCB board, the user uses the external control switch and power supply to start the second electric telescopic rod 13. The start of the second electric telescopic rod 13 drives the positioning plate 21 to move. The movement of the positioning plate 21 drives the adaptive rubber pad 22 to move, thereby releasing the positioning of the PCB board. At this time, the user uses the external control switch and power supply to start the second motor 12. The start of the second motor 12 drives the card plate 203 to rotate, and the rotation of the card plate 203 drives the PCB to rotate, so that the PCB is rotated ninety degrees. At this time, the user uses the external control switch to start the first electric telescopic rod 14. The start of the first electric telescopic rod 14 drives the positioning rod 15 to move. The movement of the positioning rod 15 drives the slide 202 to move. The movement of the slide 202 drives the card plate 203 to move, so that the card plate 203 is separated from the PCB. Then the second motor 12 is started again to restore the card plate 203 to its original angle. Then, the first electric telescopic rod 14 is used to move the card plate 203 again, so that the card plate 203 covers the PCB. Then, the second electric telescopic rod 13 is used again to position the PCB.The other side of the PCB board can then be polished, and the above steps can be repeated to complete the polishing of all four sides of the PCB board. The movement of the movable rod 201 is consistent with the transmission speed of the conveying equipment. The four sides of the PCB board can be polished before the movable rod 201 moves to the position of the fixed plate 401, achieving the purpose of polishing the PCB board during the conveying process. At the same time, the four sides of the PCB board can also be polished, which makes it more convenient for operators to transport and polish the PCB board. Operators do not need to manually rework and polish the four sides separately, which reduces the operator's workload and increases the efficiency of PCB board processing, ensuring the polishing effect of the PCB board during the conveying process.

[0044] Example 2

[0045] See also Figure 1-9 The dust reduction mechanism 3 includes a collection box 301, which is placed on the top of the card plate 203. The top of the collection box 301 is clamped with a cover plate 302, and the inner wall of the cover plate 302 is fixedly installed with a fan 305. The input end of the fan 305 is fixedly connected with a connecting pipe 303, one end of the connecting pipe 303 passes through the outer side of the cover plate 302 and extends to the inner cavity of the card plate 203, and a dust hood 304 is fixedly installed on one end of the connecting pipe 303, so as to achieve the purpose of collecting dust. During the polishing process of the PCB board, the dust can be conveniently collected to prevent the dust from floating in the air and being inhaled into the body of the operator, causing harm to the operator. At the same time, it can also reduce the impact of dust on the conveying equipment, and prevent a large amount of dust from entering the interior of the conveying equipment and causing the conveying equipment to malfunction, thereby ensuring the service life of the conveying equipment and the safety of the operator.

The cover 302 is made of iron, and the magnet 16 is adsorbed on the surface of the cover 302. By setting the buckle 17 and the magnet 16 for use together, the buckle 17 can drive the magnet 16 to move, and the magnet 16 is adsorbed on the surface of the cover 302, so that the collection box 301 can be positioned, so that the collection box 301 will not be separated from the cover 302, thereby ensuring the stability of dust collection, and then ensuring that the conveying equipment will not be affected by the dust, and ensuring the stability of the conveying equipment during operation.

[0047] The specific implementation of this embodiment is as follows: when conveying and polishing PCB boards, the user uses an external control switch and power supply to start the fan 305. The start of the fan 305 sucks the dust generated by the polishing belt 208 polishing the PCB boards into the connecting pipe 303 through the dust suction hood 304, and then transports the dust to the inside of the collection box 301 through the connecting pipe 303. At this time, after the dust inside the collection box 301 is fully collected, the user pulls the buckle 17 to drive the magnet 16 to move, so that the magnet 16 is separated from the cover 302. At this time, the user can disassemble the collection box. After disassembly, the collected dust can be centrally processed, thereby achieving the purpose of dust collection. During the polishing process of the PCB boards, the dust can be conveniently collected to prevent the dust from floating in the air and being inhaled by the operator, causing harm to the operator. At the same time, the impact of the dust on the conveying equipment can be reduced, and a large amount of dust can be prevented from entering the conveying equipment and causing the conveying equipment to malfunction, thereby ensuring the service life of the conveying equipment and the safety of the operator.

The second motor 12 is started to drive the card plate 203 to rotate, and the rotation of the card plate 203 drives the PCB to rotate, so that the PCB is rotated ninety degrees. At this time, the user uses the external control switch to start the first electric telescopic rod 14, and the start of the first electric telescopic rod 14 drives the positioning rod 15 to move. The movement of the positioning rod 15 drives the slide 202 to move, and the movement of the slide 202 drives the card plate 203 to move, so that the card plate 203 is separated from the PCB. Then the second motor 12 is started again to restore the card plate 203 to its original angle. Then the first electric telescopic rod 14 is used to move the card plate 203 so that the card plate 203 covers the PCB. Then the second electric telescopic rod 13 is used again to position the PCB.The other side of the PCB board can be polished, and then the above steps can be repeated to complete the polishing of the four sides of the PCB board. The movement of the movable rod 201 is consistent with the transmission speed of the conveying equipment. The four sides of the PCB board can be polished before the movable rod 201 moves to the position of the fixed plate 401. When the PCB board is conveyed and polished, the user uses the external control switch and power supply to start the fan 305. The start of the fan 305 sucks the dust generated by the polishing belt 208 polishing the PCB board into the connecting pipe 303 through the dust collection hood 304, and the dust is discharged through the connecting pipe 303. The dust is transported to the inside of the collection box 301. At this time, after the dust inside the collection box 301 is fully collected, the user pulls the buckle 17 to drive the magnet 16 to move, so that the magnet 16 is separated from the cover 302. At this time, the user can disassemble the collection box. After disassembly, the collected dust can be centrally processed. After polishing the PCB board, the operator rotates the guide plate 402. The rotation of the guide plate 402 is rotated by the connecting rod 20 and the movable ball 19. In the process of rotating the guide plate 402, the operator can rotate the guide plate 402 by the connecting rod 20 and the movable ball 19. The movable ball 19 can be rotated to any angle, making it convenient for users to guide PCB boards of different sizes. The guide plate 402 can be positioned by the damping friction pad 18, making the guide plate 402 more stable during the PCB guiding process. The guide plate 402 will not rotate when not subjected to strong external forces, ensuring the stability of the guide plate 402 and achieving the purpose of positioning the guide plate 402. After the PCB board is polished, the PCB board contacts the fixed plate 401 and is transported by the conveying equipment to the position of the guide plate 402, so that the guide plate 402 guides the PCB board, thereby conveniently arranging and guiding the PCB board, achieving the purpose of polishing the PCB board during transportation. At the same time, the four sides of the PCB board can be polished, making the operator's transportation and polishing process more convenient. The operator does not need to manually rework the four sides separately, which reduces the operator's workload and increases the efficiency of PCB processing, ensuring the polishing effect of the PCB board during transportation.
