However, due to the lack of structural support for the PCB on the drilling platform, displacement of the PCB can occur during the drilling process, thus affecting drilling accuracy.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] This embodiment discloses a PCB board drilling fixture, the overall structure of which is as follows: Figure 1 As shown, it includes a frame 1, which serves as a structural support for the installation of other structural components.

[0037] like Figure 1 As shown, the PCB board drilling fixture in this embodiment also includes: an adjustment mechanism 7, a drilling platform 5, a clamping mechanism 6, a lifting platform 3, and a high-speed drilling machine 12.

[0038] The adjustment mechanism 7 is positioned above the frame 1 and includes an X-axis shifting mechanism and a Y-axis shifting mechanism. The drilling platform 5 is used to place the PCB board and is positioned above the adjustment mechanism 7. Under the action of the X-axis shifting mechanism and the Y-axis shifting mechanism of the adjustment mechanism 7, the drilling platform 5 can be moved and adjusted along the X-axis or Y-axis direction, thereby realizing the adjustment of the drilling position of the PCB board.

[0039] like Figure 2 As shown, the PCB board drilling fixture disclosed in this embodiment has a drilling platform 5 that forms an elevated placement platform using a support base 51. Several support bases 51 are evenly distributed on the platform surface of the drilling platform 5, that is, the support bases 51 are evenly spaced at equal intervals, and the several support bases 51 are distributed longitudinally and laterally to form a PCB board placement platform.

[0040] The spaced support bases 51 have gaps between them, which facilitates the high-speed drilling machine 12 to penetrate the PCB board to form vias.

[0041] The support base 51 is typically configured as a column with a top frustum panel. An anti-slip pad is fixedly laid on the top surface of the frustum panel. The protective pad is usually made of rubber or silicone with anti-slip texture. When the PCB board is placed on the support base 51, the anti-slip pad not only prevents slippage but also protects the PCB board.

[0042] Preferably, to enable rapid positioning of the PCB board during placement, as well as... Figure 2 As shown, a limiting plate 52 is fixed at one end of the platform surface of the drilling platform 5. The limiting plate 52 supports a certain height, so that the limiting plate 52 is higher than the height of the supporting base 51. Thus, after the PCB board is placed on the supporting base 51, the limiting plate 52 can play a limiting and blocking role at one end.

[0043] Accordingly, considering the protection of the PCB board, such as Figure 3 As shown, a protective pad 53 is fixed to the surface of the limiting plate 52, and the protective pad 53 has a notch 54.

[0044] Therefore, when placing the PCB board, under the guidance of the limiting plate 52, one end of the PCB board is placed against the limiting plate 52, so that the edge of that end of the PCB board is inserted into the notch 54. The notch 54 is narrow, only wide enough to block the edge of that end of the PCB board. Furthermore, the positional spacing and number of the support bases 51 are usually customized according to the frequently processed PCB boards. Therefore, based on the limiting effect of the limiting plate 52, the PCB board can be quickly placed on the support base 51.

[0045] Furthermore, to address the issue of displacement that easily occurs when placing traditional PCB boards due to the lack of a fixed structure, the PCB board drilling fixture disclosed in this embodiment is equipped with a clamping mechanism 6.

[0046] For example Figure 2 As shown, the clamping mechanism 6 is located on the rear side of the drilling platform 5, and includes a miniature clamping motor 61, a mounting bracket 62, and a clamping plate 63.

[0047] The mounting bracket 62 serves as a structural support and is fixedly installed on the rear side of the drilling platform 5. The entire mounting bracket 62 is an inverted L-shaped plate, and the platform extending from its top is used for the installation of the miniature clamping motor 61.

[0048] The miniature clamping motor 61 is a miniature telescopic motor. The output end of the miniature clamping motor 61 is connected to the clamping plate 63. The shaft of the miniature clamping motor 61 moves up and down, driving the clamping plate 63 to move up and down. Correspondingly, in order to enable the clamping plate 63 to form a clamping and positioning effect, there is a support base 51 directly below the clamping plate 63. Thus, under the action of the clamping plate 63 and the corresponding support base 51, the PCB board can be clamped to prevent the PCB board from shifting during drilling.

[0049] For the clamping mechanism 6, one or more sets can be set according to the specific width of the drilling platform 5.

[0050] Furthermore, the lifting platform 3 has the capability to adjust its height in the Z-axis direction and is used for mounting the high-speed drilling machine 12. Specifically, the lifting mechanism 3 is supported on the frame 1 by a gantry frame 2, and the high-speed drilling machine 12 is mounted on the front side of the lifting mechanism 3.

[0051] Driven by the lifting mechanism 3, the high-speed drilling machine 12 can be adjusted in height. The lifting mechanism 3 drives the high-speed drilling machine 12 to move down and make the drill bit of the high-speed drilling machine 12 contact the PCB board to complete the drilling process.

[0052] Therefore, for the PCB board drilling fixture disclosed in this embodiment, the support base raises the placement position of the PCB board. Since the support base is customized according to the frequently processed PCB board, the gap between the support bases is used as a selective drilling point. Thus, the gap between the support bases 51 facilitates the high-speed drilling machine 12 to penetrate the PCB board to form a via.

[0053] Furthermore, a limiting plate 52 and a clamping mechanism 6 are added. The limiting plate has the function of quick positioning, and together with the clamping mechanism 6, it can fix the PCB board, thereby reducing the probability of displacement during the PCB board drilling process and improving the accuracy of drilling.

[0054] Example 2

[0055] This embodiment discloses a PCB board drilling fixture. Based on the structure of the PCB board drilling fixture disclosed in Embodiment 1, the specific structural implementation of the adjustment mechanism 7 and the lifting mechanism 3 is further defined.

[0056] First, the adjustment mechanism 7 includes an X-axis shifting mechanism whose position can be adjusted along the X-axis direction, and a Y-axis shifting mechanism whose position can be adjusted along the Y-axis direction.

[0057] The X-axis shifting mechanism is specifically configured as follows: the X-axis shifting mechanism includes an X-axis reciprocating motor 71, an X-axis guide module 72, and an X-axis platform 73; the output end of the X-axis reciprocating motor 71 is connected to the X-axis platform 73, the guide rails of the X-axis guide module 72 are laterally distributed on the frame 1, and the slider of the X-axis guide module 72 is connected to the X-axis platform 73.

[0058] Therefore, the X-axis reciprocating motor 71 reciprocates to pull the X-axis platform 73, and under the guidance of the X-axis guide module 72, the X-axis platform 73 can make reciprocating linear motion along the X-axis, thereby realizing the position adjustment in the X-axis direction.

[0059] Similarly, the Y-axis shifting mechanism is set up on the same principle as the X-axis shifting mechanism. The Y-axis shifting mechanism includes: a Y-axis reciprocating motor 74, a Y-axis guide module 75, and a Y-axis platform 76. The output end of the Y-axis reciprocating motor 74 is connected to the Y-axis platform 76. The guide rails of the Y-axis guide module 75 are longitudinally distributed on the X-axis platform 73, and the slider of the Y-axis guide module 75 is connected to the Y-axis platform 76.

[0060] Therefore, the Y-axis reciprocating motor 74 reciprocates to pull the Y-axis platform 76, and under the guidance of the Y-axis guide module 75, the Y-axis platform 76 can make reciprocating linear motion along the Y-axis, thereby realizing the position adjustment in the Y-axis direction.

[0061] Considering that the Y-axis shifting mechanism is located above the X-axis shifting mechanism, in order to ensure that the Y-axis shifting mechanism does not interfere with the operation of the X-axis moving mechanism, such as... Figure 1 As shown, the Y-axis moving mechanism can also move along the X-axis.

[0062] The specific configuration includes: a Y-axis reciprocating motor 74 is mounted on a sliding frame 9, the sliding frame 9 is fixed on a moving block 10, the moving block 10 is slidably assembled in a U-shaped slide groove 8, and the U-shaped slide groove 8 is fixed on the frame 1 and distributed parallel to the X-axis guide module 72.

[0063] Furthermore, after the adjustment mechanism 7 is fully set up, a drilling platform 5 is installed above the Y-axis platform 76. The two are assembled using mounting posts 4 at the four corners. The mounting posts 4 at the four corners are of the same height, and after passing through the mounting holes of the drilling platform, they can be locked to the Y-axis platform by threads.

[0064] Secondly, the specific structural settings for lifting platform 3 are as follows: Figure 1 As shown, the lifting mechanism 3 includes a lifting motor 31, a lever, a top platform 32, a main support frame 34, and a lifting plate 35;

[0065] Considering that the lifting platform 3 is also located behind the drilling platform 5, a portal frame structure 2 is used to support the lifting platform 3, so as not to affect the operation of the Y-axis shifting mechanism.

[0066] The support frame 34 of the lifting platform 3 is fixedly connected to the gantry frame 2, and the support frame 34 serves as the basic support for the lifting platform 3 for the installation of other structural components.

[0067] A top platform 32 is assembled and fixed above the support frame 34 via a column 33. A lifting motor 31 is mounted on the top platform 32, and the output end of the lifting motor 31 is connected to a lead screw lever. The lead screw lever passes through the top wall of the support frame 34 and is fitted with a lead screw nut, which is fixedly connected to the lifting plate 35. Thus, the lifting motor 31 drives the lifting plate 35 to move up and down. A high-speed drilling machine 12 is assembled on the front side of the lifting plate 35 via a mounting bracket 11, so that the high-speed drilling machine 12 can move up and down with the lifting plate 35.

[0068] Preferably, guide rods can be installed on both sides of the lead lever, and guide sleeves are fitted over the guide rods. The guide sleeves are also fixedly connected to the lifting plate 35. Thus, under the action of the guide rods, the stability of the up-and-down lifting motion of the high-speed drilling machine 12 can be improved.

[0069] Therefore, the PCB board drilling fixture disclosed in this invention can effectively reduce the possibility of PCB board displacement by pressing and fixing the PCB board during the PCB board drilling process, thereby improving the drilling accuracy.

[0070] The above embodiments are not intended to limit the present invention, nor is the present invention limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present invention are also within the protection scope of the present invention.
