Description

Technical Field

[0001] The invention relates to the field of circuit board production, and in particular to a vertical printing auxiliary feeding device. Background Art

[0002] Screen printing refers to using a silk screen as a base and making a screen printing plate with images through a photosensitive platemaking method. Screen printing consists of five major elements: screen printing plate, scraper, ink, printing table and substrate. Printing is based on the basic principle that the mesh holes of the screen printing plate with images can pass through the ink, while the mesh holes of the non-image parts cannot pass through the ink.

[0003] PCB, Chinese name for printed circuit board, also known as printed circuit board, is an important electronic component, the support of electronic components, and the carrier for the electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board.

[0004] At present, for PCB multi-track feeding vertical printing machines, when manual loading is performed, the PCB boards need to be manually delivered to the position of each feeding frame. When a feeding frame is far away from the person, the employee needs to stretch his arm to the limit to load the materials. The employee is prone to fatigue and the body is prone to leaning forward and falling into the machine, which poses a great safety hazard. When loading, the staff sets the PCB board vertically on the positioning mechanism. However, the PCB board is easily deformed by external force when placed vertically, and the PCB board also has a flexible circuit board, which has a poor use effect and is not convenient for clamping and loading operations.

[0041] The pressing plate module 8 can press the PCB board after it is placed to ensure that it is in a flat state when the PCB board is in a vertical state, further avoiding deformation of the PCB board, and at the same time making the device more adaptable to the flexible circuit board, increasing the applicability and use effect of the device.

[0042] The use process of the vertical printing auxiliary feeding device provided by the present invention is as follows: Before placing the PCB board, start the electric telescopic rod 73, and drive the cleaning gas bin 71 to rise through the electric telescopic rod 73. At this time, start the air pump body 77, and open the control valve 76 on the air inlet pipe 79 and the connecting hose 74 at the same time, so that the gas enters the inside of the air pump body 77 through the air inlet pipe 79 and the purification device 714, and is further transported to the inside of the cleaning gas bin 71 through the connecting hose 74, so that the gas is ejected through the cleaning port 72, thereby cleaning the surface of the positioning substrate 610. After cleaning, the electric telescopic rod 73 drives the cleaning gas bin 71 to reset, and closes the control valve 76 on the connecting hose 74 and the air inlet pipe 79 at the same time; When placing the PCB board, the PCB board is placed on the positioning substrate 610 and is limited by the limiting roller 103. At this time, the air pump body 77 is started again, and the control valve 76 on the exhaust pipe 75 and the negative pressure pipe 78 is opened, so that the air pump body 77 discharges the gas inside the connecting chamber 710 through the negative pressure pipe 78, thereby making the inside of the connecting chamber 710 in a negative pressure state, and then the fixed suction cup 711 adsorbs and fixes the PCB board through the connecting pipe 713; After the PCB is fixed, the drive motor 87 is started, and the gear 86 is driven to rotate by the drive motor 87. Since the drive gear 86 is meshed with the transmission gear 85, the shaft member 812 and the winding wheel 84 are rotated, and the connecting cable 83 is wound, so that the connecting cable 83 pulls the installation frame 810 and compresses the telescopic spring rod 811. When the installation frame 810 moves to the moving position, the electric rod 89 is started, and the PCB board pressing plate 88 is driven to descend by the electric rod 89 to press the PCB to ensure its flatness. When loading, the flip motor 66 is started, and the flip motor 66 drives the connecting roller 65 and the positioning base plate 610 to rotate 90 degrees, so that the PCB board is in a vertical state, and then the horizontal motor 68 and the vertical motor 69 drive the horizontal screw rod 62 and the vertical screw rod 67 to operate to adjust the position of the movable base 64, so that the PCB board corresponds to the position of the vertical printing auxiliary feeding mechanism 1 when loading, so as to complete the loading positioning; After confirming that the PCB board has been positioned, the touch switch starts the vertical printing auxiliary feeding mechanism 1 to start the action, and the PCB board body 4 is clamped by the PCB board clamping mechanism 5. At this time, the driving motor 87 is reversed to restore the telescopic spring rod 811. At the same time, the electric rod 89 drives the PCB board pressing plate 88 to separate from the PCB board body 4, and the fixed suction cup 711 cancels the fixation of the PCB board body 4.
