Specific implementation manners

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0029] The PCB board processing production line includes: a processing device, a carrier, a picking device and a track, wherein a loading station, a unloading station, a flipping station and a station to be processed are arranged on the track; the processing device is located above the station to be processed, the loading station and the unloading station are respectively located on both sides of the processing device, and the flipping station and the unloading station are located on the same side of the processing device; the carrier is located on the track, and the carrier is used to carry the PCB board; the picking device is used to grab the PCB board. Specifically, the PCB board processing production line includes a processing device 10, a first track 21, a second track 22, a first platform 31 and a second platform 32. The first track 21 and the second track 22 are arranged in parallel up and down, the second track 22 is arranged above the first track 21, the processing device 10 is arranged on the second track 22, the first platform 31 and the second platform 32 are respectively used to carry the PCB board 40, the first platform 31 and the second platform 32 can move back and forth along the first track 21 or the second track 22, and switch between the first track 21 and the second track 22. The first track 21 has a loading station 51 and a station to be processed 52, the second track 22 has a unloading station 53 and a flipping station 55, the processing device 10 is arranged above the station to be processed 52, the loading station 51 and the unloading station 53 are respectively located on both sides of the processing device 10, and the flipping station 55 and the unloading station are located on the same side of the processing device 10.

[0030] The first carrier 31 and the second carrier 32 both include a first motion path and a second motion path. The first motion path is configured to move from the loading station 51 to the processing station 52 along the first track 21; the second motion path is configured to move from the first track 21 to the second track 22 to reach the processing device 10. When the processing device is in the processing state, after the second carrier moves to the loading station to be loaded, the second carrier moves along the first motion path to the processing station to wait; when the processing device completes the processing of the PCB board on the first carrier, the second carrier on standby at the processing station moves along the second motion path to the processing device, so that the processing device processes the PCB board on the second carrier, and the first carrier and the second carrier alternately transport the PCB board to the processing device, and the processing device continues processing. When the first carrier is located at the processing device and is in the processing state, the second carrier moves to the processing station and waits. When the PCB board on the first carrier is processed, the first carrier leaves the processing device, and the second carrier moves from the processing station to the processing device. When the second carrier is at the processing device and is in the processing state, the first carrier moves to the processing station and waits. This process is repeated, and the first carrier and the second carrier alternately transport PCB boards to the processing device, and the processing device continues processing.

[0031] See also Figure 1, which is a schematic structural diagram of the anti - stacking plate system in the first embodiment of this application. The anti - stacking plate system is applied to the PCB board processing production line and is used to monitor the situation of two stacked PCB boards. The anti - stacking plate system includes: a first sensing unit 61 and a host computer; the first sensing unit 61 is arranged on the loading station 51 of the PCB board processing production line, and the first sensing unit 61 is used to detect whether there is a PCB board on the first carrier 31 at the loading station before loading. When the first sensing unit 61 detects that there is a PCB board on the first carrier, it sends a first trigger signal; the host computer is used to give a stacking alarm after receiving the first trigger signal.

[0032] Specifically, before loading at the loading station, the first sensing unit detects whether there is a PCB board on the first carrier at the loading station. When it detects that there is a PCB board at the loading station, the first sensing unit sends a first trigger signal to the host computer. After receiving the first trigger signal, the host computer gives an alarm to remind the operator that there is already a PCB board on the first carrier at this time, and it should be prohibited to load the first carrier to cause the occurrence of the stacking situation.

[0033] In a specific embodiment, please refer to Figure 2 , the anti - stacking plate system further includes: a second sensing unit 62; the second sensing unit 62 is arranged on the unloading station 53 of the PCB board processing production line, and the second sensing unit 62 is used to detect whether there is a PCB board on the second carrier at the unloading station after unloading. When it detects that there is a PCB board on the second carrier, it sends a second trigger signal to the host computer; the host computer is used to give a stacking alarm after receiving the second trigger signal.

[0034] Specifically, after unloading at the unloading station, the second sensing unit detects whether there is a PCB board on the second carrier at the unloading station. When it detects that there is a PCB board at the unloading station, the second sensing unit sends a second trigger signal to the host computer. After receiving the second trigger signal, the host computer gives an alarm to remind the operator that there is already a PCB board on the second carrier at this time, and it should be prohibited to continue loading after moving the second carrier to the loading station to cause the occurrence of the stacking situation.

[0035] PCB boards can be divided into single - sided boards and double - sided boards. Single - sided boards are the most basic PCB boards. Components are concentrated on one side, and conductors are concentrated on the other side (when there are surface - mount components, they are on the same side as the conductors, and plug - in devices are on the other side). Double - sided boards have wiring on both sides. However, to use the conductors on both sides, appropriate electrical connections must be made between the two sides.

[0036] In a specific embodiment, please refer to Figure 3The anti-overlapping system further includes: a third sensing unit 63; the third sensing unit 63 is disposed on the flipping station 55 of the PCB board processing production line, and the third sensing unit 63 is used to detect whether there is a second PCB board on the second carrier when the picking device of the PCB board processing production line flips the first PCB board to be flipped, and when it is detected that there is a second PCB board on the second carrier, a third trigger signal is sent to the host computer; the host computer is used to issue an overlapped board alarm after receiving the third trigger signal.

[0037] Specifically, when the PCB board is a double-sided board, the PCB board needs to be turned over on the flipping station 55 after one side is processed. When the picking device grabs the PCB board after one side is processed, since the carrier is usually provided with a magnetic suction function, the picking device will only grab one PCB board and leave the carrier. The third sensing unit detects whether there is a PCB board on the second carrier when the picking device flips the PCB board after one side is processed. When the third sensing unit detects that there is still a PCB board on the second carrier, it means that the second carrier has overlapped, and the third sensing unit sends a third trigger signal to the host computer; after receiving the third trigger signal, the host computer sends an alarm to remind the operator that the second carrier has overlapped.

[0038] In a specific implementation, the anti-overlapping system further includes: a forced stop unit; the forced stop unit is in communication with the first sensing unit, the second sensing unit and the third sensing unit, and is used to send a stop command to the processing device of the PCB board processing production line to stop the operation of the processing device after receiving any of the first trigger signal sent by the first sensing unit, the second trigger signal sent by the second sensing unit and the third trigger signal sent by the third sensing unit. By setting up the forced stop unit, it is avoided that the PCB board processing production line continues to work in the case of overlapping, resulting in serious processing errors or serious processing deviations.

[0039] In order to avoid a collision between the platform on standby at the processing station 52 and the platform at the processing device 10, in a specific embodiment, when the first platform 31 is set to run from the processing device 10 to the unloading station 53, the second platform 32 on standby at the processing station 52 is started to run to the processing device 10, so as to avoid a collision between the two platforms at the processing station 52 and the processing device 10; or when the second platform 32 is set to run from the processing device 10 to the unloading station 53, the first platform 31 on standby at the processing station 52 is started to run to the processing device 10, so as to avoid a collision between the two platforms at the processing station 52 and the processing device 10.

[0040] In a specific embodiment, when the first carrier 31 or the second carrier 32 reaches the loading station 51 and the PCB board 40 previously carried on the first carrier 31 or the second carrier 32 has been completed, the loading is started.

[0041] When the first carrier 31 or the second carrier 32 reaches the unloading station 53 and the PCB board 40 carried on the first carrier 31 or the second carrier 32 has been completed, the unloading is started.

[0042] When the first carrier 31 or the second carrier 32 reaches the unloading station 53 and the single side of the PCB board 40 carried on the first carrier 31 or the second carrier 32 is completed, the turning over is started.

[0043] In the above embodiment, whether the PCB board 40 carried on the first carrier 31 or the second carrier 32 has been completed or whether the single side is completed can be obtained according to the marking information on the board surface of each processed PCB board 40 recorded by the line scanning device, or can be obtained through a program according to the movement rules of the first carrier 31 and the second carrier 32, or a combination of the above two methods.

[0044] Please refer to Figure 4 , which is the flowchart of the anti-overlapping board method in the second embodiment of the present application, applied to the anti-overlapping board system in the above first embodiment, and is used to monitor the situation of two PCB boards overlapping. The anti-overlapping board system includes: a first sensing unit and a host computer. The first sensing unit is arranged at the loading station of the PCB board processing production line. The anti-overlapping board method includes: the first sensing unit detects whether there is a PCB board on the first carrier at the loading station before loading. When the first sensing unit detects that there is a PCB board on the first carrier, the first sensing unit sends a first trigger signal; after receiving the first trigger signal, the host computer performs an overlapping board alarm.

[0045] In a specific embodiment, please refer to Figure 5 , the anti-overlapping board system further includes: a second sensing unit. The second sensing unit is arranged at the unloading station of the PCB board processing production line. The anti-overlapping board method further includes: the second sensing unit detects whether there is a PCB board on the second carrier at the unloading station after unloading. When the second sensing unit detects that there is a PCB board on the second carrier, the second sensing unit sends a second trigger signal to the host computer; after receiving the second trigger signal, the host computer performs an overlapping board alarm.

[0046] In a specific embodiment, please refer to Figure 6, the anti-overlapping plate system further includes: a third sensing unit, which is disposed at the flipping station of the PCB board processing production line. The anti-overlapping plate method further includes: the third sensing unit detects whether there is a PCB board on the second carrier when the picking device of the PCB board processing production line flips the PCB board. When it detects that there is a PCB board on the second carrier, it sends a third trigger signal to the host computer; the host computer is used to perform overlapping plate alarm after receiving the third trigger signal.

[0047] Specifically, initially, the first carrier 31 is disposed on the first track 21 and is located at the loading station 51, and the second carrier 32 can be located at any position of the station to be processed 52 and the unloading station 53. The first carrier 31 is loaded at the loading station 51, that is, the PCB board 40 is carried on the first carrier 31. Before loading, the first sensing unit detects whether there is a PCB board on the carrier at the loading station. If there is, the first sensing unit sends a first trigger signal to the host computer, and the host computer does not alarm; if not, loading is performed. After loading, the first carrier 31 moves from the loading station 51 to the station to be processed 52 along the above-mentioned first movement path to standby. When the processing device 10 is in an idle state, the first carrier 31 standby at the station to be processed 52 reaches the processing device 10 along the above-mentioned second movement path, so that the processing device 10 processes the PCB board 40 on the first carrier 31. When the processing device 10 is in a processing state, the second carrier 32 runs to the loading station 51. After loading, the second carrier 32 moves from the loading station 51 to the station to be processed 52 along the above-mentioned first movement path to standby.

[0048] Both the first carrier 31 and the second carrier 32 further include a third movement path and a fourth movement path. The third movement path is configured to move from the processing device 10 to the unloading station 53 along the second track 22; the fourth movement path is configured to move from the unloading station 53 to the first track 21 and move along the first track 21 to the loading station 51. After the processing device 10 finishes processing the PCB board on the first carrier 31, the second carrier 32 standby at the station to be processed 52 moves to the processing device 10 along the second movement path for processing. At the same time, the first carrier 31 moves to the unloading station 53 along the above-mentioned third movement path, and the completed PCB board 40 is unloaded. After unloading, the second sensing unit detects whether there is a PCB board on the carrier at the unloading station. If there is, the second sensing unit sends a second trigger signal to the host computer, and the host computer does not alarm; if not, the first carrier 31 returns to the loading station 51.

[0049] Under normal operating conditions, one stage performs a fourth motion path, and the other stage should be at the processing device 10 for processing. If the device malfunctions and the stage at the waiting-for-processing station 52 cannot rise to the processing device 10, and the other stage after processing is triggered to execute the instruction for the fourth motion path, it may collide with the stage with a malfunction at the waiting-for-processing station 52. To avoid collisions, in a specific embodiment, when the first stage 31 executes the fourth motion path and the waiting-for-processing station 52 is not in an idle state, the first stage 31 stops on the fourth motion path to avoid collision between the stages, or when the second stage 32 executes the fourth motion path and the waiting-for-processing station 52 is not in an idle state, the second stage 32 stops on the fourth motion path to avoid collision between the stages and the stage at the waiting-for-processing station 52.

[0050] The first stage 31 continues to move along the above-mentioned fourth motion path to the loading station 51, is re-loaded, and the first sensing unit repeatedly detects whether there is a PCB on the first stage 31. Then it reaches the waiting-for-processing station 52 again along the above-mentioned first motion path to standby. The first stage 31 and the second stage 32 alternately transport the PCB 40 to the processing device 10, and the processing device 10 continues to process.

[0051] When processing a double-sided PCB, after the processing device finishes processing the PCB on the first stage, the second stage 32 waiting at the waiting-for-processing station 52 moves along the above-mentioned second motion path to the processing device 10 for processing. At the same time, the first stage 31 moves along the above-mentioned third motion path to the flipping station 55, and the single-sided processed PCB needs to be flipped to the unprocessed side. When the picking device flips the PCB, the third sensing unit detects whether there is a PCB on the stage during the flipping of the PCB. If there is, the third sensing unit sends a third trigger signal to the host computer, and the host computer gives an alarm for stacked boards; if not, the first stage 31 with the flipped PCB continues to move along the fourth motion path and the first motion path to reach the waiting-for-processing station again to standby. The first stage 31 and the second stage 32 alternately transport the PCB 40 to the processing device 10, and the processing device 10 continues to process. Specifically, the devices for performing unloading or picking can be an unloading device and a flipping device respectively, or the actions of unloading and flipping can be completed by one device, such as a manipulator.

[0052] In a specific embodiment, the anti - stacking plate system further includes a forced stop unit, and the method further includes: if the forced stop unit receives any one of the first trigger signal sent by the first sensing unit, the second trigger signal sent by the second sensing unit, and the third trigger signal sent by the third sensing unit, it issues a stop instruction to the processing device of the PCB board processing production line to stop the operation of the processing device. By setting the forced stop unit, it is avoided that in the case of plate stacking, the PCB board processing production line still continues to work, resulting in serious processing errors or serious processing deviation, etc.

[0053] Preferably, in a specific embodiment, the first track 21 further has a standby parking space 54, and the standby parking space 54 corresponds to the blanking station 53. When the first carrier 31 or the second carrier 32 executes the fourth movement path, and at the same time the processing station 52 is not in an idle state, the first carrier 31 or the second carrier 32 stops at the standby parking space 54. By setting the standby parking space 54, it is avoided that the first carrier 31 or the second carrier 32 stops at any position of the fourth movement path, which may affect the operation of other devices.

[0054] The third embodiment of the present application provides a PCB board processing system, including: a PCB board processing production line and the anti - stacking plate system as described in any one of the first embodiments of the present application. By setting the sensing unit to detect whether there is a PCB board on the carrier before loading at the loading station, after unloading at the unloading station, and when flipping the PCB board, when the sensing unit detects that there is a PCB board on the carrier, the sensing unit sends a trigger signal to the host computer, and the host computer receives the trigger signal to give an alarm, realizing the monitoring of the situation of two PCB boards being stacked, and avoiding the occurrence of processing errors or serious processing deviation.

[0055] In a specific embodiment, the PCB board processing system further includes a line scanning device. The line scanning device is located between the loading station 51 and the processing station 52. The line scanning device scans the information of the PCB board 40 moving from the loading station 51 to the processing station 52. The line scanning device is stationary relative to the track, and the PCB board 40 completes the scanning during movement, that is, as long as the PCB board 40 moves from the loading station 51 to the processing station 52, the line scanning device scans the PCB board 40. The information of the PCB board 40 scanned by the line scanning device at least includes marking information for marking the surface of the PCB board 40 to record and identify the PCB board 40 and its surface for this processing. This marking information can be used to guide the processing pattern of the processing device 10, as well as to guide blanking or turning over. The information of the PCB board 40 scanned by the line scanning device can also include an image of the surface of the PCB board 40, etc., which can be used to check the processing progress and / or processing quality of the surface of the PCB board 40.

[0056] In a specific embodiment, the PCB board processing system further includes a camera device. The camera device is disposed between the workpiece station 52 to be processed and the blanking station 53. The camera device is used to monitor the processed PCB board 40 to detect the processing quality. In the above embodiment, the camera device being disposed between the workpiece station 52 to be processed and the blanking station 53 includes being disposed at the corresponding workpiece station 52 to be processed and at the corresponding blanking station 53.

[0057] Further, in a specific embodiment, the camera device is a CCD camera to perform high-definition imaging on the local structure of the PCB board 40 and monitor the processing quality of the PCB board 40.

[0058] Specifically, the CCD camera is installed on the processing device 10. The CCD camera moves together with the processing device 10 to monitor the processing quality of the processing device 10 in real time. Of course, a separate motion mechanism can also be provided for the camera device.
