Description

Technical Field

[0001] The present invention relates to the field of electronic technology, and in particular to an automatic processing device for circuit boards. Background Art

[0002] With the rapid development of electronic technology, circuit boards are increasingly widely used. For example, circuit boards in various structures in automobiles, mobile phone circuit boards, earphone circuit boards, smart watch circuit boards, etc. all need to burn some system program information into the circuit boards. Therefore, burning devices have emerged on the market, and the system program information is burned into the circuit boards by using the burning devices, which improves the work efficiency.

[0003] However, the burned circuit boards will accumulate magnetic powder, which affects subsequent matters and causes the phenomenon of reading errors. In the prior art, in order to remove dust from the burned circuit boards, manual dust removal is often used, and the fibers on the circuit boards are gently brushed off with a brush. This requires a large amount of manual operation, resulting in high labor costs. Moreover, the work efficiency of manual wiping and dust removal is unstable, the work quality is not uniform, and it is easy to get tired after long-term work. Summary of the Invention

[0004] Objective of the present invention: In order to overcome the defects of the prior art, the present invention provides an automatic processing device for circuit boards, which automatically wipes and removes dust and performs electrostatic treatment on the burned circuit boards by using the device, which is more convenient, saves labor costs, and can also improve work efficiency.

[0005] Technical solution of the present invention: An automatic processing device for circuit boards, including a placement table for placing the circuit boards to be burned, a burning table, a work table, and a loading manipulator for clamping the circuit boards to be burned on the placement table to the burning table and clamping the burned circuit boards on the burning table to the work table. A burning mechanism is provided on the burning table. A turntable, a first driving member for driving the turntable to rotate, and a loading station, a wiping station, a dust removal station, and a blanking station are sequentially arranged along the circumference of the turntable are provided on the work table. A processing table is provided on the turntable corresponding to each station, and a first placement groove for placing the circuit board is provided on each processing table. A brush head and a driving component for driving the brush head to move are provided on the wiping station. A dust removal box, an ion gun, and a blower are provided on the dust removal station. The dust removal box is hollow to form a cavity. The ion gun is provided on the dust removal box, and the end extends into the cavity. Openings for the processing table to enter and exit the cavity are provided on both sides of the dust removal box, and side plates are movably provided at both openings to open and close the openings. A blanking manipulator for clamping the dust-removed circuit boards outside the work table is provided on the blanking station.

[0006] With the above technical solution, the loading manipulator picks up the circuit board from the placement table and places it on the programming table. Then, the circuit board on the programming table is programmed by the programming mechanism. After programming is completed, the loading manipulator is used to clamp the circuit board on the programming table to the loading station, waiting for the processing table on the turntable to rotate to the loading station. Then, the circuit board at the loading station is clamped into the first placement groove on the processing table. The first driving member drives the turntable to rotate, and the processing table is rotated towards the first wiping station. After rotating to the first wiping station, the driving assembly drives the brush head to move to wipe the circuit board on the processing table. After wiping, the turntable rotates, and the processing table is rotated from the opening of the dust removal box into the dust removal box. Dust removal is performed by an ion gun, and the dust-removed substances are adsorbed outside the dust removal box by a blower. After dust removal is completed, it leaves from the other opening of the dust removal box. Finally, the unloading manipulator picks up the circuit board after dust removal, completing the processing of the entire circuit board. Through automatic wiping and dust removal, it is more convenient, has high efficiency, and good processing effects.

[0007] A further setting of the present invention: A pressing plate and a first air cylinder for driving the pressing plate to move towards the processing table are further provided at the wiping station. The pressing plate is arranged above the circuit board, and a plurality of through holes are provided on the pressing plate corresponding to the positions of the circuit board to be wiped. The driving assembly drives the brush head to move in and out of the through holes.

[0008] With the above further setting, when the processing table containing the circuit board rotates to the wiping station, the first air cylinder at the station drives the pressing plate to move towards the processing table, and the pressing plate presses on the circuit board. Then, by controlling the brush head to move in and out of the through holes, the circuit board is wiped. The setting of the pressing plate prevents the circuit board from moving during wiping, causing the circuit board to shift and affecting subsequent operations.

[0009] A further further setting of the present invention: The driving assembly includes a first guide rail arranged along the X-axis, a second guide rail arranged along the Y-axis, and a third guide rail arranged along the Z-axis. The first guide rail is arranged parallel to the pressing plate and is arranged above the pressing plate. The first guide rail is slidably arranged on the second guide rail through a first sliding seat. The third guide rail is slidably arranged on the first guide rail through a second sliding rail. The brush head is slidably arranged on the third guide rail through a third sliding seat, and a driving motor for driving the brush head to move up and down is provided on the third guide rail.

[0010] With the above further further setting, the brush head can be controlled in all directions, making the wiping of the circuit board by the brush head more comprehensive.

[0011] A further further further setting of the present invention: A pressing rod and a second air cylinder for driving the pressing rod to move up and down are provided in the cavity corresponding to the position of the first placement groove. The pressing rod is arranged above the processing table. An installation plate is provided on the output shaft of the second air cylinder, and the end of the pressing rod is arranged on the installation plate.

[0012] With the above further setting, the pressing rod can press the circuit board on the processing table in the dust removal box, so that the circuit board will not shift from the first placement groove during dust removal, making it more stable and facilitating the subsequent clamping of the circuit board by the blanking manipulator.

[0013] A further setting of the present invention: It further includes a quick docking mechanism. The quick docking mechanism includes an electrical box and a first electrical connector arranged on the turntable. The electrical box is arranged between the wiping station and the dust removal station. There are several first electrical connectors, which are arranged in one-to-one correspondence with the processing tables and are located on one side of the processing tables. Under the placement grooves on each processing table, there are several first probes and a third cylinder for driving the first probes to move up and down. In the electrical box, there is a second electrical connector and a fourth cylinder for driving the second electrical connector to move towards the first electrical connector. The second electrical connector is provided with an air path connector and several second probes. The first electrical connector is correspondingly provided with an air inlet connector for docking with the air path connector and an electrical contact piece for docking with the second probes. The air inlet connector is connected to the first cylinder, and the electrical contact piece is connected to the first probe.

[0014] With the above further setting, when the turntable rotates and the first electrical connector on the turntable corresponds to the electrical box, the fourth cylinder drives the second electrical connector to move towards the first electrical connector, so that the second probes contact the electrical contact pieces, and the air path connector contacts the air inlet connector, realizing electrical supply. The electrical contact pieces are connected to the first probes to supply power to the first probes. The air inlet connector is connected to the first cylinder to supply air to the first cylinder, so that the first cylinder drives the first probes to move, and the first probes contact the circuit board to realize electrical connection.

[0015] A further setting of the present invention: The programming mechanism includes a programming cavity, a programming seat for carrying the circuit board to be programmed, and a second driving member for driving the programming seat to slide into the programming cavity. The programming seat is provided with a programming groove.

[0016] With the above further setting, the structure is simple and the operation is convenient.

[0017] A further setting of the present invention: A waiting table is provided at the loading station, and a second placement groove corresponding to the programming groove on the programming seat is provided on the waiting table.

[0018] With the above further setting, since the programming time is longer than the wiping and dust removal times, after several circuit boards are programmed, they are placed on the waiting table, and then the circuit boards are clamped onto the processing table in batches for wiping and dust removal in sequence. This can prevent the wiping and dust removal mechanisms from stopping working due to the long programming time, making the overall processing efficiency high.

[0019] A further setting of the present invention: A buffer spring is sleeved on the brush head, a connecting sleeve is sleeved on the outer periphery of the buffer spring, the brush head extends into the connecting sleeve, a connecting head is provided on the output shaft of the driving motor, the connecting head extends into the connecting sleeve and is in contact with the buffer spring.

[0020] With the above further setting, when the brush head moves towards the circuit board, the buffer spring relieves the impact force of the brush head and prevents the brush head from damaging the circuit board.

[0021] A further setting of the present invention: A lower vision transmitter for detecting the structural features of the lower end face of the circuit board is provided on the placement table, and an upper vision transmitter for detecting the structural features of the programming groove is provided on the loading manipulator.

[0022] With the above further setting, the lower vision transmitter images the structural features of the lower end face of the circuit board clamped by the manipulator, so as to know the situation of the lower end of the circuit board. When the loading manipulator clamps the circuit board onto the programming table, the upper vision transmitter can image the structural features of the programming groove on the programming seat and compare and analyze them with the structural features of the lower end face of the circuit board, so that the circuit board can be placed in the corresponding programming groove on the programming seat, making the placement of the circuit board in the correct position, with a more stable structure and not affecting subsequent programming.

[0042] Such as Figures 1-15As shown in the figure, an automatic processing device for a circuit board includes a placement table 1 for placing the circuit board 100 to be programmed, a programming table 2, a workbench 3, and a loading manipulator 4 for clamping the circuit board 100 to be programmed on the placement table 1 to the programming table 2 and clamping the programmed circuit board 100 on the programming table 2 to the workbench 3. A programming mechanism 21 is provided on the programming table 2. The programming mechanism 21 includes a programming cavity 22, a programming seat 23 for carrying the circuit board 100 to be programmed, and a second driving member 24 for driving the programming seat 23 to slide into the programming cavity 22. The second driving member 24 is arranged as a cylinder. A fourth guide rail 25 is provided on the programming table 2, and the programming seat 23 slides on the fourth guide rail 25. A programming groove 231 is provided on the programming seat 23. The specific programming structure is prior art, so it will not be specifically elaborated here. A turntable 31, a first driving member for driving the turntable 31 to rotate, and a loading station 5, a wiping station 6, a dust removal station 7, and an unloading station 8 are sequentially arranged along the circumference of the turntable 31 on the workbench 3. The first driving member is arranged as a motor. The wiping station 6 can be provided with one or two. After multiple wipings, the circuit board 100 becomes cleaner. A processing table 32 is provided corresponding to each station on the turntable 31. Sensors can be provided on the processing table 32. Of course, the sensors can also be provided on the workbench 2. In this way, at the loading station 5, after the circuit board 100 is clamped onto the processing table 32, the first driving member starts to work, driving the turntable 31 to rotate to convey the circuit board 100. A first placement groove 321 for placing the circuit board 100 is provided on each processing table 32, making the structure of the circuit board 100 stable and facilitating subsequent processing. A brush head 61 and a driving assembly 62 for driving the brush head 61 to move are provided at the wiping station 6. A dust removal box 71, an ion gun 72, and a blower 73 are provided at the dust removal station 7. The dust removal box 71 is hollow to form a cavity 70. The ion gun 72 is provided on the dust removal box 71, and its end extends into the cavity. The ion gun 72 can remove dust and static electricity from the circuit board 100. The blower 73 adsorbs the dust in the cavity to the outside of the cavity. To prevent the circuit board 100 from shifting when the blower 73 is working, a pressing rod 74 and a second cylinder 75 for driving the pressing rod 74 to move up and down are provided in the cavity corresponding to the position of the first placement groove 321. The pressing rod 74 is arranged above the processing table 32. An installation plate 751 is provided on the output shaft of the second cylinder 75. The end of the pressing rod 74 is arranged on the installation plate 751. The pressing rod 74 can press the circuit board 100 on the processing table 32 in the dust removal box 71, so that the circuit board 100 will not deviate from the first placement groove 321 during dust removal and is more stable. Openings 76 for the processing table 32 to enter and exit the cavity are provided on both sides of the dust removal box 71. Side plates 77 are movably provided at both openings to open and close the openings 76. A sliding groove 711 is provided on the dust removal box 71, and the two side plates 77 are slidably arranged in the corresponding sliding grooves 711. When it is necessary to open the opening 76, the side plate 77 slides upward.The processing table 32 can enter the cavity from the opening 76. Similarly, after the dust removal is completed and it needs to exit the cavity, the side plate on the other side is slid upward to expose the opening 76. Through the sliding setting, the situation where the side plate 77 cannot be opened due to other structures on the turntable 31 is avoided, which is more convenient and saves space. The blanking station 8 is provided with a blanking manipulator 9 for clamping the dust-removed circuit board 100 outside the workbench 2. The loading manipulator 4 picks up the circuit board 100 from the placement table 1 and places it on the programming table 2. Then, the circuit board on the programming table 2 is programmed by the programming mechanism 21. After the programming is completed, the loading manipulator 4 is used to clamp the circuit board on the programming table 2 to the loading station 5 and wait for the processing table 32 on the turntable 32 to rotate to the loading station 5. Then, the circuit board on the loading station 5 is clamped into the placement groove 321 on the processing table 32. The first driving member drives the turntable 31 to rotate, and the processing table 32 is rotated towards the wiping station 6. After rotating to the wiping station 6, the driving assembly drives the brush head 61 to move to wipe the circuit board on the processing table 32. Then, the turntable 31 rotates, and the processing table 32 is rotated from the opening 76 of the dust removal box 71 into the dust removal box 71. Dust removal is performed by the ion gun 72, and the dust-removed substances are adsorbed outside the dust removal box 71 by the blower 73. After the dust removal is completed, it leaves from the other opening 76 of the dust removal box 71. Finally, the blanking manipulator 9 picks up the dust-removed circuit board to complete the processing of the entire circuit board. Through automatic wiping and dust removal, it is more convenient, has high efficiency, and good processing effect.

[0043] In this embodiment, the wiping station 6 is further provided with a pressing plate 63 and a first cylinder 64 for driving the pressing plate 63 to move towards the processing table 32. The pressing plate 63 is arranged above the circuit board 100. A plurality of through holes 631 are provided on the pressing plate 63 corresponding to the positions to be wiped on the circuit board. The through holes 631 correspond to the positions that need to be wiped, and the positions that do not need to be wiped are blocked by the pressing plate 63. The driving assembly 62 drives the brush head 61 to enter and exit the through holes 631. When the processing table 32 containing the circuit board 100 rotates to the wiping station 6, the first cylinder 64 at the station drives the pressing plate 63 to move towards the processing table 32, and the pressing plate 63 is pressed on the circuit board 100. Then, by controlling the brush head 61 to enter and exit the through holes 631, the circuit board 100 is wiped. The setting of the pressing plate 63 prevents the circuit board 100 from moving during wiping, causing the circuit board to shift and affecting subsequent operations.

[0044] In this embodiment, the driving assembly 62 includes a first guide rail 621 arranged along the X-axis, a second guide rail 622 arranged along the Y-axis, and a third guide rail 623 arranged along the Z-axis.

The first guide rail 621 is slidably arranged on the second guide rail 622 through a first sliding seat 65. The third guide rail 623 is slidably arranged on the first guide rail 621 through a second sliding rail 66.

A plurality of first probes 322 and a third air cylinder 323 for driving the first probes 322 to move up and down are provided below the first placement groove 321 on each processing table 32. A second electrical connector 103 and a fourth air cylinder 104 for driving the second electrical connector 103 to move towards the first electrical connector 102 are provided in the electrical box 101. An air path connector 105 and a plurality of second probes 106 are provided on the second electrical connector 103. An air inlet connector 107 for docking with the air path connector 102 and an electrical contact piece 108 for docking with the second probe 106 are correspondingly provided on the first electrical connector 102. The air inlet connector 107 is connected to the first air cylinder 64, and the electrical contact piece 108 is connected to the first probe 322. When the turntable 31 rotates and the first electrical connector 102 on the turntable 31 corresponds to the electrical box 101, the fourth air cylinder 104 drives the second electrical connector 103 to move towards the first electrical connector 102, so that the second probe 106 contacts the electrical contact piece 108, and the air path connector 105 contacts the air inlet connector 107, realizing electrical supply. The electrical contact piece 108 is connected to the first probe 322 to supply power to the first probe 322.

[0046] In this embodiment, a waiting table 33 is provided at the loading station 5. A second placement groove 331 corresponding to the programming groove 231 on the programming seat 23 is provided on the waiting table 33. Since the programming time is longer than the wiping and dust removal time, after several circuit boards are programmed, they are placed on the waiting table 33, and then the circuit boards are clamped onto the processing table 32 in batches for wiping and dust removal in sequence. This can prevent the wiping and dust removal mechanisms from stopping working due to the long programming time, resulting in high overall processing efficiency.

[0047] In this embodiment, a buffer spring is sleeved on the brush head 61. A connecting sleeve 612 is sleeved on the outer periphery of the buffer spring. The brush head 61 extends into the connecting sleeve 612. A connecting head 681 is provided on the output shaft of the driving motor 68. The connecting head 681 extends into the connecting sleeve 612 and is in contact with the buffer spring. The buffer spring relieves the impact force of the brush head 61 when it moves towards the circuit board, preventing the brush head from damaging the circuit board.

[0048] In this embodiment, a lower vision transmitter 11 for detecting the structural features of the lower end face of the circuit board 100 is provided on the placement table 1, and an upper vision transmitter 41 for detecting the structural features of the programming groove 231 is provided on the loading manipulator 4. The lower vision transmitter 11 takes an image of the structural features of the lower end face of the circuit board 100 clamped by the loading manipulator 4 and transmits it to the computer, so as to know the situation at the lower end of the circuit board. When the loading manipulator 4 clamps the circuit board onto the programming table 2, the upper vision transmitter 41 can take an image of the structural features of the programming groove 231 on the programming seat 23 and transmit it to the computer, and compare and analyze it with the structural features of the lower end face of the circuit board. Thus, the circuit board 100 can be placed in the corresponding programming groove 231 on the programming seat 23, making the placement of the circuit board in the correct position, with a more stable structure and not affecting subsequent programming.
