DETAILED DESCRIPTION

The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] It is understandable that, referring to Figures 1 to 5 The present invention provides a PCB board drilling device, including a frame 100 and a positioning mechanism 400. The frame 100 is provided with a support platform 200 and a drilling mechanism 300. The upper end surface of the support platform 200 is provided with a positioning groove 210, and the PCB board can be inserted into the positioning groove 210. The bottom wall of the positioning groove 210 is protruding with a plurality of vertical positioning pins 220. The plurality of positioning pins 220 are arranged at intervals. The positioning pins 220 can be inserted into the positioning holes of the PCB board. The drilling mechanism 300 is located above the support platform 200 and is used to drill holes in the PCB board. ; The positioning mechanism 400 is arranged on one side of the supporting platform 200. The positioning mechanism 400 includes a first driving member 410, a second driving member 420 and a positioning pin 430. The fixed end of the second driving member 420 is connected to the movable end of the first driving member 410. The first driving member 410 is used to drive the second driving member 420 to move toward or away from the positioning groove 210. The positioning pin 430 is vertically connected to the movable end of the second driving member 420. The second driving member 420 is used to drive the positioning pin 430 to move up and down so that the positioning pin 430 can abut the upper end surface of the PCB board.

[0029] When in use, the PCB board is first embedded in the positioning groove 210, and the multiple positioning pins 220 are correspondingly inserted into the positioning holes of the PCB board. The horizontal position of the PCB board is positioned by the cooperation of the positioning groove 210 and the multiple positioning pins 220, which can reduce the hole position deviation caused by the horizontal position deviation of the PCB board, thereby improving the drilling processing accuracy. Then, the first driving member 410 drives the second driving member 420 to move in the direction close to the positioning groove 210, thereby driving the positioning pin 430 to move synchronously until the positioning pin 430 moves to the edge position of the PCB board. The second driving member 420 drives the positioning pin 430 to move downward, so that the positioning pin 430 abuts the upper end surface of the PCB board and cooperates with the bottom wall of the positioning groove 210 to press the vertical position of the PCB board, which can reduce the up and down shaking of the PCB board during drilling, so that the PCB board can be positioned below the drilling mechanism 300, and the PCB board is drilled by the drilling mechanism 300, thereby improving the drilling processing accuracy.

[0030] In addition, by having the positioning pins 430 abut against the edge of the PCB to locate the vertical position of the PCB, the impact on the graphic area at the center of the PCB can be reduced.

[0031] It should be noted that the shape of the positioning groove 210 matches the shape of the PCB board, so that the PCB board can be embedded in the positioning groove 210 and positioned. In addition, the vertical depth of the positioning groove 210 is less than or equal to the thickness of the PCB board, so that the PCB board can partially protrude from the notch of the positioning groove 210 or be flush with the notch position, so that the positioning pin 430 can abut the upper end surface of the PCB board, thereby positioning the vertical position of the PCB board.

[0032] The first driving member 410 and the second driving member 420 can both be air cylinders, oil cylinders or electric push rods, etc., which can drive corresponding components to perform corresponding actions.

[0033] It is understandable that, referring to Figures 2 to 4 The positioning pin 430 includes a cap 431 that is capable of abutting the upper end surface of the PCB. The cap 431 is square in shape, and one side surface of the cap 431 is parallel to one side surface of the positioning slot 210. Since the cap 431 is square in shape and one side surface of the cap 431 is parallel to one side surface of the positioning slot 210, compared to a round cap 431, the square cap 431 can increase the contact area between the cap 431 and the PCB, thereby increasing the force-bearing area of ​​the PCB and improving the pressing force. This can reduce the possibility of the PCB shaking due to vibration and disperse the force, thereby reducing the possibility of the PCB being damaged by pressure.

[0034] It should be noted that the width of the nail cap 431 can be kept unchanged and the length of the nail cap 431 can be increased so that the nail cap 431 can increase the contact area with the PCB board without contacting the graphic area of ​​the PCB board, thereby reducing the possibility of the PCB shaking up and down due to vibration.

[0035] It is understandable that, referring to Figure 4 The movable end of the second driving member 420 is fixedly connected to the mounting block 440, and the positioning pin 430 includes a pin rod 432, which is threadedly connected to the mounting block 440. Because the pin rod 432 is threadedly connected to the mounting block 440, the positioning pin 430 can be removed and replaced by simply twisting the positioning pin 430, thereby improving the ease of installation and removal of the positioning pin 430. In addition, because the mounting block 440 is fixedly connected to the movable end of the second driving member 420, the second driving member 420 can drive the mounting block 440 to move upward and downward, thereby driving the positioning pin 430 to move upward and downward.

[0036] Specifically, refer to Figure 3 and Figure 4 The support platform 200 is slidably connected to a slider 230, which can slide toward or away from the positioning slot 210. The slider 230 is provided with a vertical guide hole 231, and the nail rod 432 is passed through the guide hole 231. Since the support platform 200 is slidably connected to the slider 230, the slider 230 is provided with a vertical guide hole 231, and the nail rod 432 is passed through the guide hole 231, when the positioning pin 430 moves toward or away from the positioning slot 210, it can drive the slider 230 to move synchronously, and guide the nail rod 432 to move vertically through the guide hole 231, which can improve the lifting stability of the positioning pin 430, thereby improving the stability of the pressing.

[0037] It is understandable that, referring to Figure 3 and Figure 5 The upper end of the positioning pin 220 is configured to be hemispherical. When the position of the PCB board is adjusted so that the positioning pin 220 can be aligned with and penetrate the positioning hole of the PCB board, the upper end of the positioning pin 220 abuts against the lower end surface of the PCB board. Since the upper end of the positioning pin 220 is configured to be hemispherical, the contact area between the PCB board and the positioning pin 220 can be reduced, thereby reducing the possibility of wear on the PCB board. In addition, the hemispherical upper end can guide the positioning pin 220 to slide into the positioning hole of the PCB board, thereby facilitating the positioning pin 220 to align with and penetrate the positioning hole of the PCB board, thereby improving the convenience of positioning.

[0038] It is understandable that, referring to Figure 3 and Figure 5The sidewall of the positioning groove 210 is provided with a groove 211, which extends to the upper end surface of the support platform 200. Since the sidewall of the positioning groove 210 is provided with a groove 211, and the groove 211 extends to the upper end surface of the support platform 200, after drilling is completed, the operator can reach into the groove 211 from the upper end surface of the support platform 200 and contact the sidewall of the PCB board, so as to facilitate the application of force to remove the PCB board, thereby improving the convenience of removing the board.

[0039] Specifically, refer to Figure 3 and Figure 5 There are two grooves 211, which are symmetrically arranged on opposite sides of the positioning groove 210. Since the two grooves 211 are symmetrically arranged on opposite sides of the positioning groove 210, it is convenient for the operator to apply force from opposite sides of the PCB to remove the PCB, further improving the convenience of removing the PCB.

[0040] It is understandable that, referring to Figure 3 There are three positioning pins 220, which are arranged in a triangle. Since the three positioning pins 220 are arranged in a triangle to form a triangular positioning structure, the positioning stability of the PCB board can be improved, thereby reducing the possibility of horizontal position deviation of the PCB board.

[0041] It is understandable that, referring to Figure 1 and Figure 3 Two sets of positioning mechanisms 400 are provided, symmetrically arranged on opposite sides of the support platform 200. The positioning mechanisms 400 on opposite sides of the support platform 200 simultaneously press and position the PCB, ensuring balanced force on both sides of the PCB. This improves the positioning stability of the PCB and reduces the possibility of the PCB shaking.

[0042] It is understandable that, referring to Figure 1 The drilling mechanism 300 includes a lifting plate 310, a third driving member 320, a plurality of fourth driving members 330, and a plurality of drill bits 340. The plurality of drill bits 340 are rotatably connected to the lifting plate 310, which is connected to the movable end of the third driving member 320. The third driving member 320 is used to drive the lifting plate 310 up and down. The fourth driving member 330 corresponds to the drill bits 340 and is used to rotate the drill bits 340. During drilling, the third driving member 320 drives the lifting plate 310 downward, thereby driving the drill bits 340 downward. Simultaneously, the fourth driving member 330 drives the drill bits 340 to rotate, thereby drilling holes in the PCB board. Since there are multiple drill bits 340 and the fourth driving member 330, and the fourth driving member 330 drives the drill bits 340 to rotate, multiple holes can be drilled simultaneously, thereby improving drilling efficiency.

[0043] It should be noted that the third driving component 320 can be a cylinder, an oil cylinder or a linear slide module, etc., which can drive the lifting plate 310 to move up and down, and the fourth driving component 330 can be a stepping motor or a servo motor, etc., which can drive the drill bit 340 to rotate.

[0044] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
