[0003] In the prior art, the processing production line of a PCB board usually includes a horizontally arranged circular track and two carriers running along the track. The carriers are used to carry the PCB board. On the one hand, the running distance of the carriers is too long, resulting in low processing efficiency. On the other hand, the floor area of the production line with a circular track is relatively large. Summary of the Invention

[0004] An object of the present invention is to overcome the above-mentioned defects existing in the prior art, and provide a method for processing a PCB board to improve the processing efficiency of the PCB board.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] A method for processing a PCB board, which is applied to a PCB board processing production line. The production line includes a processing device, a first carrier, a second carrier, and a first track and a second track arranged vertically in parallel. The second track is arranged above the first track. The processing device is arranged on the second track. The first carrier and the second carrier are respectively used to carry the PCB board. The first track has a loading station and a station to be processed. The second track has an unloading station. The station to be processed corresponds to the processing device. The loading station and the unloading station are respectively located on both sides of the processing device;

[0007] Both the first carrier and the second carrier have a first movement path and a second movement path. The first movement path is configured to move along the first track from the loading station to the station to be processed; the second movement path is configured to move from the first track to the second track;

[0008] The method includes:

[0009] When the processing device is in a processing state, after the second carrier moves to the loading station and is loaded, the second carrier moves along the first movement path to the station to be processed and waits;

[0010] After the processing device finishes processing the PCB board on the first carrier stage, the second carrier stage waiting at the to-be-processed station moves along the second movement path to the processing device, so that the processing device processes the PCB board on the second carrier stage. The first carrier stage and the second carrier stage alternately transport the PCB boards to the processing device, and the processing device continuously processes.

[0011] Implementing the embodiments of the present invention will have the following beneficial effects:

[0012] In the embodiments of the present invention, by providing two parallel upper and lower tracks, on the one hand, the horizontal floor area of the device is reduced, and the running distance of the carrier stage is reduced. On the other hand, by providing two tracks, two carrier stages and three stations, when a carrier stage carrying a PCB board is being processed, the other carrier stage can carry another PCB board and run along the other track to perform other processes such as loading, unloading or flipping before and after processing. That is, when a PCB board is in the processing state, another PCB board is being transported and is about to be processed. Then, it can ensure that the processing device continuously processes without interruption, and maximize the processing speed. Description of the Drawings

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Referring to Figures 1 to 14 , the present invention discloses a PCB board processing method, including a PCB board processing production line. The PCB board processing production line includes a processing device 10, a first track 21, a second track 22, a first carrier 31 and a second carrier 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 carrier 31 and the second carrier 32 are respectively used to carry the PCB board 40, the first carrier 31 and the second carrier 32 can both move back and forth along the first track 21 or the second track 22, and switch the movement between the first track 21 and the second track 22. The first track 21 has a loading station 51 and a to-be-processed station 52, the second track 22 has an unloading station 53, the to-be-processed station 52 corresponds to the processing device 10, and the loading station 51 and the unloading station 53 are respectively located on both sides of the processing device 10.

[0038] Both the first carrier 31 and the second carrier 32 include a first movement path and a second movement path. The first movement path is configured to move from the loading station 51 along the first track 21 to the to-be-processed station 52; the second movement path is configured to move from the first track 21 to the second track 22 and reach the processing device 10.

[0039] The PCB board processing method includes:

[0040] When the processing device is in the processing state, after the second carrier moves to the loading station and is loaded, the second carrier moves along the first movement path to the to-be-processed station to wait;

[0041] After the processing device finishes processing the PCB board on the first carrier, the second carrier waiting at the to-be-processed station moves along the second movement path to the processing device, so that the processing device processes the PCB board on the second carrier. The first carrier and the second carrier alternately transport the PCB boards to the processing device, and the processing device continuously processes.

[0042] When the first carrier stage is at the processing device and in the processing state, the second carrier stage moves to the waiting-for-processing station to standby. After the PCB on the first carrier stage is processed, the first carrier stage leaves the processing device, and the second carrier stage moves from the waiting-for-processing station to the processing device. When the second carrier stage is at the processing device and in the processing state, the first carrier stage moves to the waiting-for-processing station to standby. This process repeats, with the first and second carrier stages alternately transporting the PCB to the processing device, and the processing device continuously processes.

[0043] In the above embodiment, by setting two parallel tracks above and below, on the one hand, the horizontal floor area of the device is reduced, and the running distance of the carrier stage is decreased. On the other hand, by setting two tracks, two carrier stages, and three stations, when one carrier stage is carrying a PCB for processing, the other carrier stage can carry another PCB and run along the other track to perform other operations such as loading, unloading, or flipping before and after processing. That is, when one PCB is in the processing state, the other PCB is being transported and is about to be processed, which can ensure that the processing device continuously processes without interruption and maximize the processing speed.

[0044] Specifically, the PCB processing method includes the following steps:

[0045] 1) Refer to Figure 1 , initially, the first carrier stage 31 is set on the first track 21 and located at the loading station 51, and the second carrier stage 32 can be at any position between the waiting-for-processing station 52 and the unloading station 53.

[0046] The first carrier stage 31 is loaded at the loading station 51, that is, the PCB 40 is loaded onto the first carrier stage 31. After loading, the first carrier stage 31 moves from the loading station 51 to the waiting-for-processing station 52 along the above-mentioned first movement path to standby, as Figure 2 shown.

[0047] 2) As Figure 3 shown, when the processing device 10 is in the idle state, the first carrier stage 31 on standby at the waiting-for-processing station 52 reaches the processing device 10 along the above-mentioned second movement path, so that the processing device 10 processes the PCB 40 on the first carrier stage 31.

[0048] 3) When the processing device 10 is in the processing state, the second carrier stage 32 runs to the loading station 51. After loading, the second carrier stage 32 moves from the loading station 51 to the waiting-for-processing station 52 along the above-mentioned first movement path to standby, as Figures 3 to 5 shown.

[0049] 4) The first carrier 31 and the second carrier 32 also each include a third movement path and a fourth movement path. The third movement path is configured to move from the processing device 10 along the second track 22 to the blanking station 53; the fourth movement path is configured to move from the blanking station 53 to the first track 21 and move along the first track 21 to the loading station 51. When the processing of the PCB on the first carrier 31 by the processing device 10 is completed, the second carrier 32 waiting at the waiting processing station 52 moves along the second movement path to the processing device 10 for processing. At the same time, the first carrier 31 moves along the above-mentioned third movement path to the blanking station 53, and the completed PCB 40 is unloaded. The first carrier 31 continues to move along the above-mentioned fourth movement path to the loading station 51, is re-loaded, and then reaches the waiting processing station 52 again along the above-mentioned first movement path to wait, as Figures 5 to 10 shown, and repeating step 4), the first carrier 31 and the second carrier 32 alternately transport the PCB 40 to the processing device 10, and the processing device 10 continuously processes.

[0050] As Figures 11 to 14 shown, the PCB is a PCB that needs to be processed on both sides. For step 4), when the processing of the PCB on the first carrier by the processing device is completed, the second carrier 32 waiting at the waiting processing station 52 moves along the above-mentioned second movement path to the processing device 120 for processing. At the same time, the first carrier 31 moves along the above-mentioned third movement path to the blanking station 53, and the PCB with one side processed is flipped to the unprocessed side. The first carrier 31 carries the flipped PCB and continues to move along the fourth movement path and the first movement path to reach the waiting processing station again. Repeating step 4), the first carrier 31 and the second carrier 32 alternately transport the PCB 40 to the processing device 10, and the processing device 10 continuously processes.

[0051] The devices for performing blanking or flipping can be a blanking device and a flipping device respectively, or the actions of blanking and flipping can be completed by one device, such as a manipulator.

[0052] Reference Figures 1 to 14, in a specific embodiment, the PCB board processing production line further includes a line scanning device 60. The line scanning device 60 is located between the loading station 51 and the to-be-processed station 52. The line scanning device 60 scans the information of the PCB board 40 moving from the loading station 51 to the to-be-processed station 52. The line scanning device 60 is stationary relative to the track, and the PCB board 40 moves to complete the scanning. That is, as long as the PCB board 40 moves from the loading station 51 to the to-be-processed station 52, the line scanning device 60 scans the PCB board 40. The information of the PCB board 40 scanned by the line scanning device 60 at least includes the 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 unloading or turning over. The information of the PCB board 40 scanned by the line scanning device 60 can also include the 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.

[0053] Furthermore, in a specific embodiment, the PCB board processing production line further includes a camera device. The camera device is arranged between the to-be-processed station 52 and the unloading 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 arranged between the to-be-processed station 52 and the unloading station 53 includes being arranged at the corresponding to-be-processed station 52 and the corresponding unloading station 53.

[0054] Furthermore, 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.

[0055] Specifically, in a specific embodiment, 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 set for the camera device.

[0056] Furthermore, when the first track 21 and the second track 22 are arranged side by side vertically, preferably, lifting mechanisms can be respectively provided for the first carrier 31 and the second carrier 32. The lifting structure drives the first carrier 31 or the second carrier 32 to lift between the first track 21 and the second track 22, that is, the processing device 10 is located directly above the to-be-processed station 52 and vertically descends from the unloading station 53 to the first track 21.

[0057] According to step 4) above, under normal operating conditions, when one carrier stage executes the fourth movement path, the other carrier stage should be at the processing device 10 for processing. If a malfunction occurs in the device and the carrier stage at the waiting-for-processing station 52 cannot rise to the processing device 10, and the other carrier stage after processing is triggered to execute the instruction for the fourth movement path, it may collide with the carrier stage with a malfunction at the waiting-for-processing station 52. To avoid collisions, in a specific embodiment, when the first carrier stage 31 executes the fourth movement path and the waiting-for-processing station 52 is not in the idle state, the first carrier stage 31 stops on the fourth movement path to prevent the carrier stage from colliding with the carrier stage at the waiting-for-processing station 52. Or when the second carrier stage 32 executes the fourth movement path and the waiting-for-processing station 52 is not in the idle state, the second carrier stage 32 stops on the fourth movement path to prevent the carrier stage from colliding with the carrier stage at the waiting-for-processing station 52.

[0058] Preferably, in a specific embodiment, the first track 21 further has a standby parking position 54, and the standby parking position 54 corresponds to the unloading station 53. When the first carrier stage 31 or the second carrier stage 32 executes the fourth movement path and the waiting-for-processing station 52 is not in the idle state, the first carrier stage 31 or the second carrier stage 32 stops at the standby parking position 54. By setting the standby parking position 54, it is avoided that the first carrier stage 31 or the second carrier stage 32 stops at any position on the fourth movement path, which may affect the operation of other devices.

[0059] To avoid collisions between the carrier stage waiting at the waiting-for-processing station 52 and the carrier stage at the processing device 10, in a specific embodiment, when the first carrier stage 31 runs from the processing device 10 to the unloading station 53, the second carrier stage 32 waiting at the waiting-for-processing station 52 is started to run to the processing device 10 to avoid collisions between the two carrier stages at the waiting-for-processing station 52 and the processing device 10. Or when the second carrier stage 32 runs from the processing device 10 to the unloading station 53, the first carrier stage 31 waiting at the waiting-for-processing station 52 is started to run to the processing device 10 to avoid collisions between the two carrier stages at the waiting-for-processing station 52 and the processing device 10.

[0060] In a specific embodiment, when the first carrier stage 31 or the second carrier stage 32 reaches the loading station 51 and the PCB board 40 previously carried on the first carrier stage 31 or the second carrier stage 32 is completed, the loading is started.

[0061] When the first carrier stage 31 or the second carrier stage 32 reaches the unloading station 53 and the PCB board 40 carried on the first carrier stage 31 or the second carrier stage 32 is completed, the unloading is started.

[0062] When the first carrier stage 31 or the second carrier stage 32 reaches the unloading station 53 and the single side of the PCB board 40 carried on the first carrier stage 31 or the second carrier stage 32 is completed, the turning is started.

[0063] In the above embodiments, whether the PCB board 40 carried on the first carrier 31 or the second carrier 32 has been completed or only one side has been completed can be obtained based on the marking information on the surface of the PCB board 40 processed each time recorded by the line scanning device 60, 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.

[0064] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
