[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0023] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:
[0024] like Figures 1 to 6 As shown, a PCB board drilling device includes a machine platform and a drilling unit 4. The machine platform is provided with a fixedly connected gantry 11, and the drilling unit 4 is slidably connected to the gantry 11. The drilling unit 4 includes a mounting plate 3 and a drilling machine 43. The mounting plate 3 is slidably connected to the gantry 11, and a pair of slidably connected drilling machines 43 are symmetrically provided on the mounting plate 3. The drilling machines 43 on both sides are respectively installed with tools for drilling holes and drilling grooves. In this way, the drilling unit 4 realizes the integrated drilling function. The two-step drilling process does not require the PCB board to be moved again, thereby reducing the error of repositioning.
[0025] The drilling gong unit 4 is provided with a fixedly connected cleaning mechanism, which includes a cylinder 44 and a shell cover 45. The cylinder 44 is fixedly connected to the drilling gong unit 4. The telescopic end of the cylinder 44 is provided with a shell cover 45, which includes a main shell 451 and a connecting rod 454. The main shell 451 is fixedly connected to the telescopic end of the cylinder 44 through the connecting rod 454, and the main shell 451 is provided with a sealing ring 455 that matches the drilling gong machine 43. The sealing ring 455 fills the gap between the drilling gong machine 43 and the shell cover 45 to prevent debris from floating out of the gap. The shell cover 45 is provided with a radially connected air jet pipe 452 and a tangentially connected air suction pipe 453. The other ends of the air jet pipe 452 and the air suction pipe 453 are connected to the external air flow system. The external air flow system is generally an air pump. After the processing is completed, the cylinder 44 drives the shell cover 45 to move down along the drilling machine 43, so that the shell cover 45 closes the processing part of the tool and the PCB board, and the air jet 452 sprays radial turbulence to blow out the debris stuck in the gap, and the shell cover 45 prevents the debris from spreading. After that, the air cylinder 44 drives the shell cover 45 to move up a short distance, so that an air gap is formed between the shell cover 45 and the PCB board, and the suction pipe 453 draws air to the outside of the shell cover 45. Since the suction pipe 453 and the shell cover 45 are in a tangential relationship, a spiral airflow is formed at this time, which is convenient for sucking out the debris. The air jet 452 and the suction pipe 453 are both provided with a one-way valve 457. Under the action of the one-way valve 457, the air flow flows from the air jet 452 to the shell cover 45 in one direction, and flows out from the suction pipe 453 in one direction. It is prevented that the debris splashes into the suction pipe 453 during the air jet or the debris blocks the air jet 452 during the air suction. The bottom of the shell cover 45 is provided with an elastic expansion opening 456 , which can prevent the shell cover 45 from rigidly contacting the PCB board and expand the bottom area of the shell cover 45 .
[0026] A workbench 2 is provided on the machine, an X-track 12 matching the workbench 2 is provided on the machine, and an X-axis moving mechanism 21 is provided on the bottom surface of the workbench 2. The X-axis moving mechanism 21 includes an X-screw rod 211 rotatably connected to the machine at one end, the workbench 2 is threadedly connected to the X-screw rod 211, and the other end of the X-screw rod 211 is provided with an X-motor 212 fixedly connected, and the X-motor 212 is fixedly connected to the machine. The PCB board is placed on the workbench 2 for processing. The X-motor 212 drives the X-screw rod 211 to rotate, and the X-screw rod 211 drives the workbench 2 to move forward and backward horizontally, and the PCB board moves with the workbench 2.
[0027] The gantry 11 is provided with a Y track 13 that matches the mounting plate 3, and the mounting plate 3 is provided with a slider 32 that matches the Y track 13. The gantry 11 is provided with a Y-axis moving mechanism 31. The Y-axis moving mechanism 31 includes a Y screw rod 311 that is rotatably connected to the gantry 11 at one end, the mounting plate 3 is threadedly connected to the Y screw rod 311, and the other end of the Y screw rod 311 is provided with a fixedly connected Y motor 312, and the Y motor 312 is fixedly connected to the machine. The Y motor 312 drives the Y screw rod 311 to rotate, and the Y screw rod 311 drives the mounting plate 3 to move horizontally, and the drilling gong unit 4 moves with the mounting plate 3.
[0028] A moving plate 41 is provided on one side of the drilling gong unit 4 close to the mounting plate 3, a Z track matching the moving plate 41 is provided on the mounting plate 3, and a Z-axis moving mechanism 42 is provided on the mounting plate 3. The Z-axis moving mechanism 42 includes a Z screw rod 421 rotatably connected to the mounting plate 3 at one end, and the Z screw rod 421 is threadedly connected to the moving plate 41; a Z motor 422 is provided at the other end of the Z screw rod 421, and the Z motor 422 is fixedly connected to the mounting plate 3. The Z motor 422 drives the Z screw rod 421 to rotate, and the Z screw rod 421 drives the moving plate 41 to move in the vertical direction, and the moving plate 41 moves along the vertical direction with the drilling gong machine 43.
[0029] The working principle of the specific implementation of the utility model is as follows: the PCB board to be processed is fixed on the workbench 2, and the processing position of the PCB board is driven by the X-axis moving mechanism 21 and the Y-axis moving mechanism 31. Under the action of the Z-axis moving mechanism 42, the drilling and gong unit 4 can perform the process of drilling holes or gong grooves on the PCB board. The cylinder 44 drives the shell cover 45 to move downward, and the shell cover 45 isolates the processing end of the drilling and gong machine 43 and the processing part of the PCB board from the outside world. After the air jet 452 sprays radial airflow to form turbulent flow to blow out the debris, the cylinder 44 drives the shell cover 45 to move upward for a distance, so that an air gap is formed between the shell cover 45 and the PCB board, and the air suction pipe 453 draws air to the outside of the shell cover 45, and forms a spiral airflow to suck out the debris and discharge it from the shell cover 45.
