Description

Technical Field

[0001] This utility model relates to the technical field of circuit board hole plugging auxiliary equipment, and more specifically, to a circuit board hole plugging device. Background Technology

[0002] In modern electronics manufacturing, the functionality and integration of printed circuit boards (PCBs) are constantly improving, and the number and distribution of their vias are becoming increasingly complex. Typically, to meet the needs of high-density assembly and solder mask protection, some through-holes or blind vias on PCBs need to be plugged. On the one hand, plugging effectively prevents solder mask ink or other plating layers from entering the vias and causing potential problems; on the other hand, it also avoids issues such as cold solder joints and residual impurities in the vias during subsequent soldering processes.

[0003] For example, a Chinese patent (publication number: CN213368245U) discloses a circuit board plugging device, including a fixed box, a plugging machine, a motor, a conveyor belt, and circuit boards. The plugging machine is fixed to the upper surface of the fixed box, and a material placement window is opened on the front outer surface of the fixed box. A pressure plate is movably installed inside the fixed box, and a guide rod is inserted through the outer surface of the pressure plate. The top end of the guide rod is connected and fixed to the inner wall of the fixed box, and a partition is welded to the bottom end of the guide rod. The partition is connected and fixed to the inner wall of the fixed box by screws. A feeding roller is inserted through the outer surface of the partition, and a drive shaft is inserted and fixed inside the feeding roller. The drive shaft is rotatably connected to the lower surface of the partition, and a cam and a second driven gear are sleeved on the end of the drive shaft opposite to the feeding roller. This utility model facilitates automatic sorting and conveying of circuit boards, realizing the storage of multiple circuit boards at a time.

[0004] The circuit board via plugging device designed above has the following disadvantages in actual use: before being conveyed to the via plugging assembly, it does not have a structure to clean the dust in the through holes or blind holes on the circuit board. If there is dust in the through holes or blind holes on the circuit board and the vias are plugged, the quality of the via plugging will be reduced.

[0005] In view of this, a circuit board via plugging device is provided to overcome the above-mentioned defects. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a circuit board hole plugging device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

A speed-regulating motor is connected to the top of the lead screw, and the speed-regulating motor is located at the top of the vertical plate.

[0011] Preferably, the suction mechanism includes a connecting plate and a suction head. The connecting plate is disposed between the adjusting blocks and is fixedly connected. The suction head is disposed at the bottom of the connecting plate, and the hose is connected to the suction head.

[0012] Preferably, the supply mechanism includes a supply box, a supply trough, a temporary storage trough, a suction pump, and suction pipes.

[0013] Preferably, the suction tube on the right side is connected to the hose, and the suction tube at the bottom extends into the temporary storage tank.

[0014] This utility model has the following beneficial effects:

[0015] Compared with existing technologies, this circuit board via-plugging device, through a combination of multiple structures including a limiting mechanism, an adjusting mechanism, a suction mechanism, and a supply mechanism, first uses multiple sets of limiting ends to limit the circuit board at the top of the moving board, and then moves it horizontally from left to right via an electric slide rail.

[0028] In this embodiment, firstly, multiple sets of limiting mechanisms 4 limit the circuit board at the top of the moving plate 3, and then the electric slide rail 2 moves horizontally from left to right. Next, the components in multiple sets of adjusting mechanisms 6 are activated, and the suction mechanism 7 is adjusted up or down. The supply mechanism 9 cleans the dust in the through holes or blind holes on the circuit board through the hose 8 and the adjusted suction mechanism 7. This effectively cleans the dust in the through holes or blind holes on the circuit board before the hole plugging assembly 10, resulting in higher quality hole plugging of the circuit board.

The electro-hydraulic actuator 12 is fixedly connected to one side of the mounting block 11, and the limiting plate 13 is fixedly connected to one side of the electro-hydraulic actuator 12. The circuit board is placed on the top of the movable plate 3, and then the electro-hydraulic actuator 12 is activated by an external switch. The electro-hydraulic actuator 12 moves with the limiting plate 13, and the limiting plate 13 fits against one side of the circuit board. Multiple limiting plates 13 fix the circuit board.

[0030] The adjustment mechanism 6 includes an adjustment groove 14, a lead screw 15, an adjustment block 16, and a speed-regulating motor 17.

The top of the lead screw 15 is connected to the speed-regulating motor 17, and the speed-regulating motor 17 is located at the top of the vertical plate 5. The speed-regulating motor 17 is started by an external switch. The speed-regulating motor 17 drives the lead screw 15 to rotate. The outer wall of the lead screw 15 moves the adjustment block 16 and the component between them downward through the reverse thread, so that the connecting plate 18 and the component on it move downward.

[0031] The suction mechanism 7 includes a connecting plate 18 and a suction head 19. The connecting plate 18 is disposed between the adjusting blocks 16 and is fixedly connected.

The suction pump 23 is disposed in the supply trough 21. Suction pipes 24 are connected to both sides of the suction pump 23. The suction pipe 24 on the right side is connected to a flexible hose 8, and the suction pipe 24 at the bottom extends into the temporary storage trough 22. The suction pump 23, suction pipe 24, flexible hose 8, and suction head 19 are used to clean the dust in the through holes or blind holes of the circuit board. The suction dust is then transferred to the temporary storage trough 22 through the suction pipe 24 at the bottom. The cleaned circuit board is then moved horizontally into the hole plugging assembly 10 for processing.

[0033] In summary, with the help of the above-mentioned technical solution of this utility model, when using this device, firstly, the circuit board is placed on top of the moving plate 3, and then the electro-hydraulic push rod 12 is activated by an external switch. The electro-hydraulic push rod 12 moves with the limiting plate 13, and the limiting plate 13 is attached to one side of the circuit board. Multiple limiting plates 13 fix the circuit board. Next, the electric slide rail 2 moves the moving plate 3 and the circuit board with its upper limit from left to right laterally and is located below the suction end. Next, the speed regulating motor 17 is activated by an external switch. The speed regulating motor 17 rotates the lead screw 15. The outer wall of the lead screw 15 moves the adjusting block 16 and the component between them downward through the reverse thread, so that the connecting plate 18 and the component above it move downward. The dust in the through hole or blind hole of the circuit board is cleaned by the suction pump 23, suction pipe 24, hose 8 and suction head 19, and the suction dust is transferred to the temporary storage tank 22 through the suction pipe 24 below. The cleaned circuit board is driven and moved laterally into the hole plugging assembly 10 for processing.
