Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board manufacturing technology, specifically to a method for deep hole drilling of vacuum plug resin. Background Technology
[0002] With advancements in printed circuit board (PCB) technology, back-drilled vias are frequently required on PCBs. Back-drilling involves removing a portion of the copper from the via wall to prevent signal shielding on inner layers. After back-drilling, the drilled portion of the via has a larger diameter than the remaining portion. Resin plugging is typically required after back-drilling.
[0003] However, after drilling circuit boards, existing drilling equipment leaves debris on the surface of the circuit board and inside the hole walls, which requires manual cleaning. This not only increases the workload but also makes cleaning more difficult due to the narrow space inside the hole. This may lead to incomplete cleaning or increased risk of damaging the circuit board during the cleaning process, thereby affecting the production efficiency and quality of the circuit boards. Utility Model Content
[0004] The purpose of this invention is to provide a deep hole drill for vacuum plug resin with cleaning function.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows.
[0006] A deep hole drill for vacuum-sealed resin includes a base. Side plates are mounted on both sides of the upper surface of the base, and a placement plate is mounted on each side plate via a clamping mechanism. A movable plate is mounted on the upper surface of the base via a movable mechanism A, and a mounting plate is mounted on the outer surface of the movable plate. An electric actuator A is mounted on the mounting plate via a movable mechanism B. A mounting frame is mounted at the telescopic end of the electric actuator A. A motor A is mounted inside the mounting frame, and a drill bit is connected to the end of the output shaft of the motor A, extending through to the bottom of the mounting frame. A corrugated hose is mounted on the lower surface of the mounting frame, sleeved on the outside of the drill bit. A dust extraction mechanism is provided on the outside of the mounting frame.
[0007] Therefore, the clamping mechanism can fix the circuit board to two placement plates, and is suitable for fixing circuit boards of different sizes. The moving mechanism A and moving mechanism B can change the position of the drill bit to drill holes in different positions on the circuit board. During the drilling process, the corrugated hose is wrapped around the outside of the drill bit to prevent debris from spreading to other parts of the circuit board surface. The dust suction mechanism can suck up the debris inside the corrugated hose and the hole, thereby achieving self-cleaning. Drilling and cleaning are carried out simultaneously, reducing extra steps and avoiding the risk of damaging the circuit board, thereby improving the production efficiency and quality of the circuit board.
[0008] Furthermore, the clamping mechanism includes an electric push rod B installed on the side of the side plate facing away from the placement plate. A horizontal plate A is installed at the end of the telescopic end of the electric push rod B. Guide rods are connected to both ends of the outer surface of the horizontal plate A. The ends of the two guide rods extend to the other side of the side plate. The ends of the two guide rods are jointly installed with the horizontal plate B. The placement plate is located on the outside of the horizontal plate B.
[0009] Place the circuit board on both sides of the two placement plates respectively. Then activate the electric push rods B on both sides. The telescopic end of the electric push rod B drives the horizontal plate A to retract inward. Through the connection of the guide rod, the horizontal plate B is moved, thereby driving the two placement plates to move inward at the same time to clamp the circuit board and fix it.
[0010] Furthermore, the moving mechanism A includes a mounting groove formed on the upper surface of the base, a motor B is installed inside the mounting groove, a nut seat A is slidably installed inside the mounting groove, and a threaded rod A is connected to the end of the output shaft of the motor B, and the threaded rod A passes through the interior of the nut seat A and is threadedly connected to it.
[0011] By starting motor B, the threaded rod A is rotated, which in turn drives nut seat A to move along its surface, thus achieving the purpose of moving the moving plate.
[0012] Furthermore, the moving mechanism B includes a nut seat B slidably mounted inside the mounting plate, an electric push rod A mounted on the lower surface of the nut seat B, a threaded rod B rotatably connected inside the mounting plate, and the threaded rod B penetrates the interior of the nut seat B and is threadedly connected to it. A motor C is mounted on the outer surface of the moving plate, and the output shaft of the motor C is connected to the threaded rod B.
[0013] By starting motor C, the threaded rod B is rotated, which in turn drives nut seat B to move along its surface, thus achieving the purpose of moving electric push rod A.
[0014] Furthermore, the dust collection mechanism includes a fixed plate mounted on the outer surface of the mounting frame, a fan mounted on the upper surface of the fixed plate, a dust collection pipe connected to the suction end of the fan, and the end of the dust collection pipe connected to a corrugated hose. A filter screen is installed inside the horizontal tube of the dust collection pipe, and a connecting pipe is connected to the outer surface of the horizontal tube of the dust collection pipe. The connecting pipe is located on the side of the filter screen close to the corrugated hose, and a collection cylinder is threaded to the end of the connecting pipe.
[0015] By starting the fan to generate suction, this suction acts on the corrugated hose through the suction pipe, thereby sucking up the debris inside the corrugated hose. The sucked-up debris is intercepted by the filter screen and then falls into the collection cylinder through the connecting pipe, thus collecting the debris. Since the connecting pipe and the collection cylinder are connected by threads, the collection cylinder can be easily removed to process the debris inside.
[0016] Furthermore, three telescopic rods are installed on the outer surface of the horizontal plate B. The ends of the telescopic rods are connected to the placement plate, and springs are sleeved on the outer surface of the telescopic rods. The two ends of the springs are connected to the horizontal plate B and the placement plate, respectively.
[0017] The telescopic rod and spring design provide a buffer when the placement plate clamps and fixes the circuit board, preventing damage to the circuit board and improving product quality. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings.
[0025] like Figure 1-5As shown, a deep hole drill for vacuum-sealed resin includes a base 100. Side plates 101 are mounted on both sides of the upper surface of the base 100, and placement plates 102 are mounted on each side plate 101 via clamping mechanisms 200. A movable plate 103 is mounted on the upper surface of the base 100 via a movable mechanism A300. An mounting plate 104 is mounted on the outer surface of the movable plate 103, and an electric push rod A105 is mounted on the mounting plate 104 via a movable mechanism B400. A mounting frame 106 is mounted at the telescopic end of the electric push rod A105. A motor A107 is mounted inside the mounting frame 106, and a drill bit 108 is connected to the end of the output shaft of the motor A107, extending through to the bottom of the mounting frame 106. A corrugated hose 109 is mounted on the lower surface of the mounting frame 106, sleeved on the outside of the drill bit 108. A dust collection mechanism 500 is provided on the outside of the mounting frame 106.
[0026] In use, the operator first places the circuit board on both sides of the two placement plates 102. Then, the clamping mechanism 200 moves the two placement plates 102 closer together, clamping and fixing the circuit board through the inner walls of the two placement plates 102. Subsequently, the moving mechanisms A300 and B400 move the electric push rod A105 to the drilling position. Then, the electric push rod A105 lowers the mounting frame 106, and the motor A107 starts, driving the drill bit 108 to rotate, so that the drill bit 108 performs drilling operations on the circuit board. When the drill bit 108 contacts the circuit board... First, the corrugated hose 109 contacts the circuit board and encloses the drill bit 108. The debris generated by the drill bit 108 is confined inside the corrugated hose 109. At the same time, the suction mechanism 500 generates suction inside the corrugated hose 109 to remove the debris. When the electric push rod A105 pulls the drill bit 108 out of the hole, the debris inside the hole is also sucked away, thus achieving self-cleaning. Drilling and cleaning are performed simultaneously, reducing additional steps and avoiding the risk of damaging the circuit board, thereby improving the production efficiency and quality of the circuit board.
