Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a device for removing broken pins. Background Technology

[0002] During the drilling process of circuit boards, the circuit board is usually placed on a workbench, and a drilling tool drills holes in the circuit board placed on the workbench. With the continuous advancement of technology, the holes of components on circuit board products are becoming more and more precise, and the diameter of the drill bit is getting smaller and smaller. In order to save costs, manufacturers will grind and reuse the drill bit multiple times. Because the diameter of the drilling tool is relatively small, the drilling machine often experiences needle breakage during the drilling process. Currently, the machine is stopped, the location of the broken needle is manually located, and the broken needle is removed with a tool.

[0003] However, in the above methods, when the machine is stopped and the needle is manually removed after a breakage, the processing efficiency of the machine is reduced, and manual needle removal is prone to damaging the PCB board. Utility Model Content

[0004] The purpose of this invention is to provide a broken needle removal device, which aims to solve the technical problems in the prior art where manual needle removal after machine shutdown reduces the processing efficiency of the machine and easily damages the PCB board.

[0005] To achieve the above objectives, this utility model employs a broken needle removal device, comprising a displacement component, a suction nozzle, an air suction component, and an air blowing component. The displacement component is mounted on the Z-axis of a drilling machine, the suction nozzle is fixedly connected to the displacement component, and both the air suction component and the air blowing component are detachably connected to the suction nozzle.

[0006] The displacement assembly includes a cylinder and a pressure plate. The cylinder is mounted on the Z-axis of the drilling machine, and the output end of the cylinder is detachably connected to the pressure plate.

[0007] The suction assembly includes a first hollow bolt and a negative pressure tube, wherein the negative pressure tube is mounted on the suction nozzle via the first hollow bolt.

[0008] The air blowing assembly includes a second hollow bolt and a positive pressure tube, the positive pressure tube being mounted on the nozzle via the second hollow bolt.

[0009] The broken needle removal device also includes a PU sealing gasket, which is disposed below the pressure plate.

[0010] The pressure plate has an arc surface.

[0011] This utility model discloses a broken needle removal device. In practical use, the suction component and the blowing component are respectively connected to an external negative pressure pump and a fan. When a broken needle occurs during drilling, the controller calculates the location of the broken needle and controls the broken needle removal device to move to the broken needle location. The cylinder drives the pressure plate to move downward, and the pressure plate presses down on the PCB board to prevent the PCB board from being sucked up. The PU sealing ring seals the area around the broken needle to prevent negative pressure leakage. The suction nozzle is attached to the broken needle location, and the broken needle is sucked out by the suction airflow of the suction component. Then, the broken needle removal device moves to the broken needle recovery position, and the broken needle is ejected by the blowing airflow of the blowing component. This achieves the needle removal action. This method can remove broken needles in a timely manner, ensuring that the machine stops less during drilling and achieving the performance of highly efficient automated machinery. It solves the technical problems of existing technologies where manual needle removal after a broken needle occurs reduces the processing efficiency of the machine and easily damages the PCB board.

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] This utility model provides a broken needle removal device, including a displacement component, a suction nozzle 1, an air suction component and an air blowing component. The displacement component is set on the Z-axis of a drilling machine. The suction nozzle 1 is fixedly connected to the displacement component. The air suction component and the air blowing component are both detachably connected to the suction nozzle 1.

[0019] The displacement assembly includes a cylinder 2 and a pressure plate 3. The cylinder 2 is mounted on the Z-axis of the drilling machine, and the output end of the cylinder 2 is detachably connected to the pressure plate 3.

[0020] The broken needle removal device also includes a PU sealing gasket 4, which is disposed on the pressure plate 3ss;

[0021] The pressure plate 3 has an arc surface 5.

[0022] In this specific embodiment, during actual use, the suction assembly and the blowing assembly are respectively connected to an external negative pressure pump and a blower. When a broken needle 11 occurs during drilling, the controller calculates the location of the broken needle 11 and controls the broken needle removal device to move to the location of the broken needle 11. The cylinder 2 drives the pressure plate 3 to move downward, and the pressure plate 3 presses down on the PCB board 10 to prevent the PCB board 10 from being sucked up. The PU sealing ring seals around the broken needle 11 to prevent negative pressure leakage. The suction nozzle 1 is fitted to the location of the broken needle 11, and the suction assembly... The suction airflow adsorbs and picks up the broken needle 11. Then, the broken needle removal device moves to the broken needle 11 recovery position and ejects the broken needle 11 through the blowing airflow of the blowing component. This achieves the needle removal action and enables timely removal of the broken needle 11, ensuring that the machine stops less during drilling and achieving high-efficiency automated machine performance. This solves the technical problem in the prior art where manual needle removal after stopping the machine after the broken needle 11 reduces the processing efficiency of the machine and easily damages the PCB board 10.

[0023] The suction assembly includes a first hollow bolt 6 and a negative pressure tube 7, wherein the negative pressure tube 7 is mounted on the suction nozzle 1 via the first hollow bolt 6.

[0024] In this specific embodiment, the negative pressure tube 7 is installed on the suction nozzle 1 via the first hollow bolt 6, and the negative pressure tube 7 is connected to an external negative pressure pump, thereby making it easy to install and remove the negative pressure tube 7.

[0025] Secondly, the air blowing assembly includes a second hollow bolt 8 and a positive pressure tube 9, the positive pressure tube 9 being mounted on the nozzle 1 via the second hollow bolt 8.

[0026] In this specific embodiment, the positive pressure pipe 9 is installed on the suction nozzle 1 by the second hollow bolt 8, and the positive pressure pipe 9 is connected to an external fan, thereby making it easy to install and remove the positive pressure pipe 9.

[0027] In the specific use of the broken needle removal device of this utility model, the suction component and the blowing component are respectively connected to an external negative pressure pump and a fan. When a broken needle 11 occurs during drilling, the controller calculates the position of the broken needle 11 and controls the broken needle removal device to move to the position of the broken needle 11. The cylinder 2 drives the pressure plate 3 to move down, and the pressure plate 3 presses down on the PCB board 10 to prevent the PCB board 10 from being sucked up. The PU sealing ring seals around the broken needle 11 to prevent negative pressure leakage. The suction nozzle 1 is attached to the position of the broken needle 11, and the needle is removed by suction. The air intake airflow of the air assembly adsorbs and picks up the broken needle 11. Then, the broken needle removal device moves to the broken needle 11 recovery position and ejects the broken needle 11 through the blowing airflow of the air assembly, thereby realizing the needle removal action. This method can remove the broken needle 11 in a timely manner, ensuring that the machine stops less during drilling and achieving the performance of high-efficiency automated machinery. It solves the technical problem in the prior art that when the machine stops after the broken needle 11 and manual needle removal is used, the processing efficiency of the machine is reduced and the PCB board 10 is easily damaged by manual needle removal.
