Description

Technical Field

[0001] The utility model relates to a PCB printing device. Background Art

[0002] The existing PCB text identification layer is designed with white oil blocks, which are mainly used for laser engraving two-dimensional codes during the intelligent manufacturing process of the client. After the existing printing platform prints the white oil blocks on the first side and then turns over to print the text identification on the second side, if the white oil blocks come into contact with the tabletop, the white oil blocks will turn yellow, and the two-dimensional code cannot be recognized after the client laser engraves it; and after the PCB is printed, it needs to be baked, and both sides need to be printed before baking. Therefore, when rushing the construction period, the situation where the white oil blocks come into contact with the tabletop and turn yellow occurs frequently; if it is not during the rush construction period, the PCB board with white oil blocks printed on the first side needs to be placed aside and given enough time to dry, and then printing is carried out after turning it over. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a PCB printing device, which can turn over and print immediately after printing one side of the PCB to ensure the printing quality.

[0004] The utility model is realized as follows: A PCB printing device includes a printing machine, a printing platform, a frame and a controller. The printing platform and the printing machine are both arranged on the frame, and the printing platform is arranged below the printing machine;

[0005] The printing platform includes a moving mechanism, a metal plate surface, a plurality of vacuum suction cups, a plurality of vacuum adapters and a plurality of magnetic fixing rods; the moving mechanism is arranged on the frame, the metal plate surface is arranged on the moving mechanism, one end of each of the plurality of magnetic fixing rods is magnetically connected to the metal plate surface, the vacuum suction cups are arranged at the other end of the magnetic fixing rods, the number of the magnetic fixing rods, the number of the vacuum adapters and the number of the vacuum suction cups are equal, the vacuum adapters are arranged on the metal plate surface, and the vacuum adapters are connected to each vacuum suction cup; the controller is electrically connected to the printing machine and the moving mechanism.

[0006] Further, a switch is arranged on each vacuum adapter.

[0007] Further, a plurality of through holes are arranged on the metal plate surface.

[0008] The advantages of the utility model are as follows: For the PCB printing device of the utility model, when printing the same type of PCB, after printing one side of the PCB board, it can immediately turn over and print the other side of the PCB, and ensure that the just-printed white oil blocks do not contact the platform, ensuring the printing quality. And this device does not need to perform a drying operation, greatly saving the printing waiting time and greatly improving the work efficiency. Brief Description of the Drawings

[0009] The present utility model will be further described below with reference to the accompanying drawings in conjunction with embodiments.

[0013] Please refer to Figures 1 to 3 As shown, a PCB spraying device of the present utility model includes a spraying machine 1, a spraying platform 2, a frame 3 and a controller. The spraying platform 2 and the spraying machine 1 are both arranged on the frame 3, and the spraying platform 2 is arranged below the spraying machine 1;

[0014] The spraying platform 2 includes a moving mechanism 21, a metal plate surface 22, a plurality of vacuum suction cups 23, a plurality of vacuum adapters 24 and a plurality of magnetic fixing rods 25; the moving mechanism 21 is arranged on the frame 1, the metal plate surface 22 is arranged on the moving mechanism 21, one end of each of the plurality of magnetic fixing rods 25 is magnetically connected to the metal plate surface 22, the vacuum suction cups 23 are arranged at the other end of the magnetic fixing rods 25, the number of the magnetic fixing rods 25, the number of the vacuum adapters 24 and the number of the vacuum suction cups 23 are equal, the vacuum adapters 24 are arranged on the metal plate surface 22, and the vacuum adapters 24 are connected to each vacuum suction cup 23; the controller is electrically connected to the spraying machine 1 and the moving mechanism 21.

[0015] During use, the position of the magnetic fixing rods 25 can be adjusted so as to cooperate with different styles of PCB boards, so that the position of the vacuum suction cups 23 will not touch the white oil block. Just adjust the magnetic fixing rods 25 before printing each style of PCB board; the moving mechanism 21 can be directly purchased from the market and can move back and forth; the moving mechanism 21 is connected to the spraying machine 1 so that the moving mechanism 21 can be controlled to move back and forth during printing; the vacuum adapters 24 are all connected to a vacuum pump or the factory's vacuum system; place the PCB board on the spraying platform 2, the controller controls the vacuum pump or the vacuum system to start, so that the vacuum suction cups 23 firmly suck one side of the PCB board, then control the moving mechanism 21 to move the PCB board into the spraying machine 1, start spraying, move the PCB board out after spraying is completed, and then the employee turns it over to perform spraying on the other side of the PCB board.

[0016] In another preferred embodiment, a switch 241 is provided on each of the vacuum adapters 24. When printing a relatively small PCB board, the redundant vacuum adapters 24 beside can be turned off through the switch 241 so as to prevent air leakage and waste.
