[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0026] The utility model embodiment provides a PCB board drilling device, such as Figures 1 to 5 As shown, the PCB board drilling equipment includes a housing 1, a frame 2, a workbench 3, a drilling mechanism 4, an exhaust fan 5 and an air supply mechanism 6. The frame 2, the workbench 3 and the air supply mechanism 6 are installed in the housing 1, the drilling mechanism 4 is installed on the frame 2, the drilling mechanism 4 includes a spindle 41 located above the workbench 3, and a tool 42 is installed on the spindle 41. The exhaust fan 5 is installed on the housing 1, and the air supply mechanism 6 includes a supply fan 61 and an air guide plate 62, and the air guide plate 62 is used to guide the wind of the supply fan 61 to the spindle 41.

[0027] The PCB board drilling device of the utility model is provided with an air supply mechanism 6, which includes a supply fan 61 and an air guide plate 62. The air outlet of the supply fan 61 can be accurately guided to the main shaft 41 through the air guide plate 62, and is extracted by the exhaust fan 5 at the same time. The flow direction of the heat dissipation air in the hood 1 is more concentrated, the blowing is highly targeted, and the heat dissipation effect is good, so that the heat generated by the main shaft 41 and the tool 42 when the PCB board drilling device is working can be better taken away, thereby avoiding untimely heat dissipation of the main shaft 41 and the tool 42, and thermal deformation of the main shaft 41 and the tool 42 affecting the processing accuracy.

[0028] During the operation of the PCB board drilling device, the PCB board 8 to be drilled is placed on the workbench 3, and the spindle 41 drives the tool 42 to rotate to complete drilling on the PCB board 8. A suction cup or other positioning structure can be provided on the workbench 3 to fix the PCB board 8 to be drilled to prevent the PCB board 8 from moving during drilling.

[0029] Specifically, the air supply mechanism 6 is installed on the side of the frame 2 away from the workbench 3. The air guide plate 62 is installed on the frame 2, and the air supply fan 61 is installed on the air guide plate 62. The air supply fan 61 is installed on the air guide plate 62, and the air guide plate 62 guides the air of the air supply fan 61 more directly. At the same time, the air guide plate 62 not only guides the air, but also provides an installation position as an installation component of the air supply fan 61, which is convenient for the installation of the air supply fan 61. In one embodiment, the air supply fan 61 can be a centrifugal fan. Of course, in other embodiments, the air supply fan 61 can also be other types of fans. When installing specifically, in one embodiment, the air guide plate 62 can be installed on the side of the frame 2 away from the workbench 3 by screws and other fixings; in another embodiment, the air guide plate 62 can be directly welded on the side of the frame 2 away from the workbench 3. Similarly, in one embodiment, the air supply fan 61 can be installed on the air guide plate 62 by screws and other fixings; in another embodiment, the air supply fan 61 can be directly welded on the air guide plate 62.

[0030] Furthermore, the exhaust fan 5 is installed on the top of the hood 1 and opposite to the workbench 3. The air supply mechanism 6 is installed on the side of the frame 2 away from the workbench 3, and the exhaust fan 5 is installed on the top of the hood 1 and opposite to the workbench 3. The wind from the supply fan 61 of the air supply mechanism 6 passes through the wind guide plate 62 and blows accurately to the location of the main shaft 41 and the tool 42, and then can be directly drawn away by the exhaust fan 5 above. The overall path is short, and the heat can be taken away accurately and quickly to prevent the heat from dissipating elsewhere. Furthermore, there are multiple main shafts 41 and air supply mechanisms 6, and one air supply mechanism 6 is set corresponding to one main shaft 41, which improves the working efficiency and ensures the heat dissipation effect.

[0031] The air guide plate 62 includes a first inclined portion 621, a second inclined portion 622 and a vertical portion 623; the first inclined portion 621 is mounted on the frame 2, and one end away from the frame 2 is lifted toward the workbench 3; the second inclined portion 622 is connected to the first inclined portion 621 and the vertical portion 623 respectively, and the side where the second inclined portion 622 is connected to the vertical portion 623 is inclined in a direction away from the frame 2; the vertical portion 623 is vertically arranged; the air supply fan 61 is mounted on the side of the second inclined portion 622 facing the frame 2. The first inclined portion 621 facilitates the air guide plate 62 to be mounted on the frame 2, and specifically, the first inclined portion 621 can be fixed to the frame 2 by screws or welding. The supply fan 61 is installed on the side of the second inclined portion 622 facing the frame 2. At the same time, the end of the first inclined portion 621 away from the frame 2 is lifted toward the workbench 3 and is in an inclined state. The side of the second inclined portion 622 connected to the vertical portion 623 is inclined in the direction away from the frame 2, and the vertical portion 623 is located on the side away from the first inclined portion 621. In this way, the air outlet of the fan installed on the second inclined portion 622 can be more easily guided by the air guide plate 62 to the location of the main shaft 41 and the tool 42.

[0032] The spindle 41 includes a spindle chuck 411, and the tool 42 is installed on the spindle chuck 411. The spindle chuck 411 and the tool 42 are covered with a chip suction cover 43. The chip suction cover 43 can be used to connect a negative pressure pipeline, etc., to absorb the debris generated during drilling, and also to take away part of the heat, thereby improving the heat dissipation effect of the spindle 41 and the tool 42. Specifically, the drilling mechanism 4 includes a spindle clamp 44, and the spindle 41 is installed in the spindle clamp 44. The drilling mechanism 4 is further provided with a spindle clamp 44, which can facilitate the installation and fixation of the spindle 41.

[0033] Further, the PCB board drilling device includes a moving mechanism 7, which is installed on the frame 2, and the moving mechanism 7 includes a lifting plate 71, and the spindle clamp 44 is installed on the lifting plate 71. By upgrading the lifting plate 71, the spindle 41 and the tool 42 can change the working height, so that drilling can be performed on the PCB board 8. Specifically, when the PCB board drilling device is working, the spindle 41 drives the tool 42 to rotate at a high speed, and at the same time, it feeds downward under the drive of the lifting plate 71, so as to achieve drilling of the PCB board 8. The lifting and lowering of the lifting plate 71 can be achieved by driving a driving member such as a cylinder, etc., which will not be described in detail here.

[0034] The moving mechanism 7 includes a transverse plate 72, which can be installed on the frame 2 in a transversely movable manner, and a lifting plate 71 can be installed on the transverse plate 72 in a lifting manner. Driven by the transverse plate 72, the drilling mechanism 4 can achieve transverse movement, and the position of the drilling hole can be changed during drilling, so as to achieve drilling holes at different positions on the PCB board 8. Specifically, a slider can be provided on the transverse plate 72 to be slidably connected to the slide rail on the frame 2, and similarly, a slider can be provided on the lifting plate 71 to be slidably connected to the slide rail on the transverse plate 72. The transverse movement of the transverse plate 72 can be achieved by driving a driving member such as a cylinder, etc., which will not be described in detail here.
