[0023] The circuit board pre-processing line can be connected to the printing workshop. This circuit board pre-processing line is a small interconnected line, which can consist of multiple machines from one manufacturer.

[0024] In this embodiment, the production workshop layout system needs to obtain PCB board handling instructions in real time. After confirming that the PCB board handling instructions have been received, it also needs to instruct the intelligent robot subsystem to handle the target PCB board, so as to realize the flexible transfer of the target PCB board.

[0025] Furthermore, the target PCB board is transported to the board feeding machine for pre-baking treatment, and the pre-baking treated PCB board is then transferred to the inkjet printing workshop via the circuit board grinding pre-treatment line.

[0030] Optionally, the pre-baking processing workshop may further include: a centering machine and a temporary storage area for plates to be transferred.

[0031] In this embodiment, the target PCB board can also be transferred from the inkjet printing workshop to the pre-baking processing workshop. This application scenario could involve the target PCB board being transferred from the pre-baking processing workshop to the inkjet printing workshop, then from the inkjet printing workshop to the etching and stripping pre-processing workshop; then returning from the etching and stripping pre-processing workshop to the inkjet printing workshop, and finally returning from the inkjet printing workshop to the pre-baking processing workshop.

[0032] Specifically, the process of returning the PCB board from the inkjet printing workshop to the pre-baking treatment workshop involves receiving the second inkjet-printed PCB board in the pre-baking treatment workshop and curing it in a high-temperature flip-type tunnel oven to obtain a cured second inkjet-printed PCB board. Further, the cured second inkjet-printed PCB board is cooled using a solar-powered flip-type cooling machine to obtain a cooled second inkjet-printed PCB board, which is then transferred to the dual-station paper-separating intelligent robot receiving machine. Correspondingly, a centering machine and a temporary storage unit for boards awaiting transfer are also required during this process.

[0033] The inkjet printing workshop is a workshop where inkjet printing is performed on the target PCB board, and it can also handle the transfer of the target PCB board. The first tilting conveyor is a device capable of transferring PCB boards. The sun-type flipping machine is a device capable of transferring PCB boards to the etching and stripping pretreatment workshop.

[0034] In this embodiment, the inkjet printing workshop can perform inkjet printing on the received pre-baking PCB board to obtain a first inkjet PCB board; or it can receive the pre-etching and stripping PCB board transferred from the etching and stripping pre-treatment workshop and perform inkjet printing on the pre-etching and stripping PCB board to obtain a second inkjet PCB board.

It can receive the pre-baking pre-processed PCB board and is the operation required for the PCB board to be transferred from the pre-baking pre-processing workshop to the inkjet printing workshop.

[0039] Furthermore, after receiving the pre-baking PCB board, the subsequent process involves splitting the pre-baking PCB board into two streams via a split line. These two streams of pre-baking PCB boards can be stored separately in the first buffer. The purpose of this first buffer is to allow the PCB boards to be stored during subsequent maintenance processes, preventing line interruptions in the preceding processes.

[0040] Correspondingly, the next process involves using a combination of parallel line inkjet printers to digitally print the inner layer circuitry, improving efficiency and being environmentally friendly, and then storing the printed circuitry in a second buffer. Next, the PCB boards stored in the second buffer are processed via busbars, combining the parallel lines into a single line. The PCB boards are then transported to the etching and stripping pretreatment workshop via a second liftable conveyor and a sun-type flipper.

[0042] In this embodiment, the operations required for the PCB board transferred from the etching and stripping pretreatment workshop to the inkjet printing workshop are described. First, the PCB board corresponding to the etching and stripping pretreatment workshop needs to be received. The PCB board needs to be split into multiple units, and after being combined with a parallel solder resist inkjet printer, it needs to be merged and stored in a temporary storage machine.

[0043] Furthermore, the PCB board before etching and film removal is printed using character inkjet printing lines to obtain a second printed PCB board. The second printed PCB board is then transferred to the problem board sorting machine via a first split-type liftable conveyor.

[0044] Accordingly, a defective board sorting machine is used to inspect the second-printed PCB boards for defects. Based on the inspection results, the second split-type liftable conveyor is instructed to classify the PCB boards. In this embodiment, the defective board sorting machine is used to inspect the second-printed PCB boards, which can better obtain high-quality PCB boards and improve the overall quality of the PCB boards.
