Description

Technical Field

[0001] The utility model relates to the technical field of ink plugging devices, in particular to an ink plugging device. Background Art

[0002] PCBs, also known as printed circuit boards (PCBs), are important electronic components that support and connect electronic components. With rapid technological advancements, electronic products are becoming increasingly advanced. Mobile phones, computers, and televisions are becoming increasingly versatile and compact. These products place high demands on printed circuit boards (PCBs) for high quality, miniaturization, and high integration.

[0003] PCB via plugging is a common process during the board manufacturing process. Because the vias contain gas, this can lead to incomplete plugging, resulting in voids and bubbles, which can cause quality issues like oil bursting and significantly impact product functionality. Given that a single via on a circuit board can contain tens of thousands, a quality issue with even one can render the entire board scrapped. To address this issue, we have developed an ink via plugging device. Utility Model Content

[0004] The purpose of this utility model is to provide an ink plugging device to address the problem, previously mentioned, that gas in the holes to be plugged on a PCB board can easily lead to incomplete plugging, resulting in voids, bubbles, and other quality issues such as oil explosion. Given that a circuit board has tens of thousands of holes to be plugged, a quality issue with even one of them can render the entire board scrapped.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An ink plugging device includes a base, wherein a support column is fixedly installed on the four corners of the upper surface of the base, a top plate is provided above the base, and the four corners of the lower surface of the top plate are fixedly connected to the tops of the corresponding support columns, a placement groove is provided in the middle of the upper surface of the base, an air guide pad is fixedly installed in the placement groove, a circuit board is placed on the upper surface of the air guide pad, a fixed frame is movably installed around the placement groove on the upper surface of the base, a roller is rotatably connected in the fixed frame, a through hole is provided in the position of the top plate corresponding to the placement groove, an ink box is fixedly installed in the through hole, and a plurality of oil filling pipes are fixedly installed at the lower end of the ink box.

[0007] The air guide pad is used to support the circuit board. When the circuit board is placed on the air guide pad in the placement groove, the ink in the ink box is injected into the placement groove through the oil filling tube, and then the ink is attached to the upper surface of the circuit board by a roller and rolled from one side to the other to perform the ink plugging work. The ink passes through the holes of the circuit board and flows onto the air guide pad. Since the circuit board is supported by the air guide pad, a channel is provided for the ink to flow downward, so that the ink can be smoothly plugged into the holes of the circuit board.

[0008] Preferably, a plurality of parallel slide rails are fixedly mounted at equal intervals on the upper surface of the air guide pad, and a plurality of support blocks are slidably mounted on each of the slide rails. The support blocks can support the circuit board on the air guide pad without blocking the holes in the circuit board, and the support blocks can slide, thereby allowing the support blocks to adjust their positions according to different circuit boards, thereby increasing the versatility of the air guide pad.

[0009] Preferably, a long strip through hole is provided between each two of the slide rails to provide a channel for the ink to flow downward, thereby preventing the ink from accumulating on the air guide pad.

[0010] Preferably, a cavity is provided at the bottom of the base, one side surface of the cavity extends to the outside of the base, and a collection box is slidably installed in the cavity.

[0011] Preferably, the placement groove is connected to the cavity via an elongated through hole, so that the ink can flow down from the elongated through hole into a collection box in the cavity, thereby avoiding waste and pollution of the working environment.

[0012] Preferably, a slide groove is formed on the sidewalls of the fixed frame corresponding to both ends of the roller, and both ends of the roller extend into the corresponding slide groove. The slide groove and the slide rail on the air guide pad are arranged perpendicularly, so that when the roller moves along the slide groove, it does not cause the support block on the slide rail to move.

[0013] Preferably, a gear is fixedly mounted on one end of the roller, and a rack is fixedly mounted on the outer wall of the fixed frame at a position corresponding to the gear.

[0014] Preferably, a drive motor is fixedly connected to a side of the gear away from the roller, a slide is fixedly mounted on the bottom of the drive motor, and the slide is slidably connected to the lower surface of the rack. The drive motor drives the gear and the roller to rotate, and the gear and the rack mesh, so that the gear drives the roller to move along the rack.

[0015] Preferably, the upper surface of the base has a groove corresponding to each of the four corners of the fixed frame. An electric telescopic rod is fixedly mounted in each groove, with the top of the electric telescopic rod fixedly connected to the lower surface of the fixed frame. By controlling the raising and lowering of the four electric telescopic rods, the fixed frame is raised and lowered. When the rollers need to be reset, the fixed frame can drive the rollers upward first, preventing them from contacting the upper surface of the circuit board again and affecting the plugging effect.

[0016] Compared with the prior art, the above technical solution adopted by the present invention has the following technical effects:

[0017] By setting up an air guide pad and installing a support block, the circuit board is supported to prevent the circuit board from directly contacting the plane, providing a channel for the ink to flow downward from the upper surface of the circuit board, so that the ink can be smoothly plugged into the holes of the circuit board and avoid the problem of bubbles caused by incomplete plugging of the holes; by setting a slide rail on the air guide pad and slidingly connecting it to the support block, the support block can be adjusted according to the position of the hole of the circuit board, so that the air guide pad can adapt to different models of circuit boards.
