Description

Technical Field

[0001] This application relates to the technical field of printed circuit boards, and more specifically, to a positioning mechanism, a drilling platform, and a drilling system. Background Technology

[0002] With the increasing demand for computers, communications, and consumer electronics, as well as the miniaturization and integration of electronic components in medical, aerospace, and automotive fields, the demand for printed circuit boards (PCBs), as the carriers of electronic products, has also increased. As PCB circuits become increasingly complex, high-density interconnect (HDI) PCBs have emerged. Drilling is a crucial step in the manufacturing process of HDI PCBs, involving the creation of through-holes, blind vias, and buried vias to facilitate component mounting, wire connections, and electrical interconnections between multilayer boards. Therefore, controlling the drilling depth of PCBs is particularly important.

[0003] In related technologies, the drilling equipment has a drill bit and a pressure foot located below the dust suction hood, and a pin for positioning the PCB is set on the drilling platform of the printed circuit board. During the drilling process on the PCB, the pressure foot may press against the pin, which may cause the drill bit to break when drilling near the pin, affecting the stability and production efficiency of the drilling machine.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0010] In one possible implementation, the length direction of the chute forms a second tilt angle with respect to the plane containing the support plane, and the second tilt angle is complementary to the first tilt angle.

[0011] In one possible implementation, the fixing base includes a first base body and a second base body that are separately arranged and connected to each other, a positioning pin is inserted into the first base body, and a sliding groove is provided in the second base body.

[0014] Secondly, this application provides a drilling platform, comprising: a workbench for supporting a plate to be drilled; a first positioning groove extending along a first direction and a second positioning groove extending along a second direction are provided on the workbench, the first direction and the second direction being perpendicular to each other; a first pressing mechanism and a second pressing mechanism, the first pressing mechanism being slidably connected to the first positioning groove and the second pressing mechanism being slidably connected to the second positioning groove, both the first pressing mechanism and the second pressing mechanism being used to press the plate to be drilled; a first fixing mechanism and a second fixing mechanism, both provided on the workbench, the first fixing mechanism being opposite to and spaced apart from the first pressing mechanism and the second fixing mechanism being opposite to and spaced apart from the second pressing mechanism, the first fixing mechanism and the second fixing mechanism being respectively provided with a positioning post penetrating the workbench and being liftable, the positioning post being used to penetrate the positioning hole of the plate to be drilled; and a plurality of positioning mechanisms of this application, respectively arranged adjacent to the first fixing mechanism and the second fixing mechanism, the support plane of the support seat of the positioning mechanism being provided below the workbench, the positioning pin of the positioning mechanism being located above the workbench, the positioning pin being used to abut against the edge of the plate to be drilled.

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] Figure 1 This is a schematic diagram of the drilling platform provided in an embodiment of this application.

[0021] See Figure 1 This application provides a drilling platform 1000, which includes multiple positioning mechanisms 100, a worktable 200, a first pressing mechanism 300, a second pressing mechanism 400, a first fixing mechanism 500, and a second fixing mechanism 600.

[0022] The workbench 200 is used to support the plate to be drilled. The workbench 200 is provided with a first positioning groove 201 extending along a first direction X and a second positioning groove 202 extending along a second direction Y. The first direction X and the second direction Y are perpendicular to each other. Optionally, the workbench 200 has a rectangular table structure, where the first direction X is the direction of the long side of the workbench 200 and the second direction Y is the direction of the short side of the workbench 200. Both the first positioning groove 201 and the second positioning groove 202 are elongated grooves. Multiple first positioning grooves 201 are spaced apart along the second direction Y of the workbench 200, and multiple second positioning grooves 202 are spaced apart along the first direction X of the workbench 200, and the first positioning grooves 201 and the second positioning grooves 202 do not intersect each other.

[0023] The first pressing mechanism 300 is slidably connected to the first positioning groove 201, and the second pressing mechanism 400 is slidably connected to the second positioning groove 202. Both the first pressing mechanism 300 and the second pressing mechanism 400 are used to press the plate to be drilled. The first pressing mechanism 300 slides inward from the short edge of the worktable 200 along the first positioning groove 201, and the second pressing mechanism 400 slides inward from the long edge of the worktable 200 along the second positioning groove 202. The two mechanisms contact the edges of the plate to be drilled and push the plate to be drilled to move until the other edges of the plate to be drilled abut against the positioning pins 22 of the positioning mechanism 100 provided on the worktable 200. The first pressing mechanism 300 and the second pressing mechanism 400 stop sliding. Then the first pressing mechanism 300 and the second pressing mechanism 400 descend toward the worktable 200 and press the plate to be drilled, completing the coarse positioning of the plate to be drilled.

[0024] The first fixing mechanism 500 and the second fixing mechanism 600 are both mounted on the worktable 200. The first fixing mechanism 500 is opposite to and spaced apart from the first pressing mechanism 300, and the second fixing mechanism 600 is opposite to and spaced apart from the second pressing mechanism 400. The first fixing mechanism 500 and the second fixing mechanism 600 are each provided with a positioning post that penetrates the worktable 200 and can be raised and lowered. The positioning post is used to penetrate the positioning hole of the plate to be drilled. Multiple positioning mechanisms 100 are respectively arranged adjacent to the first fixing mechanism 500 and the second fixing mechanism 600. The plate to be drilled has a positioning hole pre-set for positioning. After the edge of the plate to be drilled abuts against the multiple positioning mechanisms 100 to complete the coarse positioning, the first fixing mechanism 500 and the second fixing mechanism 600 respectively push the positioning post upward to penetrate the positioning hole of the plate to be drilled, so as to accurately position the plate to be drilled in the first direction X and the second direction Y, so as to facilitate subsequent drilling of the plate by drilling equipment.

[0025] In some embodiments, both the first pressing mechanism 300 and the second pressing mechanism 400 include a pressing member and a second driving device. The second driving device is used to drive the pressing member to be vertically and retractably inserted into the first positioning groove 201 or the second positioning groove 202. Optionally, the pressing member includes a mushroom-shaped pressing member and a support rod for supporting the pressing member. The support rod is inserted into the first positioning groove 201 or the second positioning groove 202 and connected to the output end of the second driving device. The second driving device can be any one of a cylinder, an electric push rod, and a hydraulic cylinder. After the plate to be drilled is roughly positioned on the worktable 200, the second drive device drives the pressing component to descend and press it onto the plate to be drilled. After the drilling equipment completes the drilling task on the plate to be drilled, the second drive device drives the pressing component to rise and release the plate to be drilled. Then, the first pressing mechanism 300 slides along the first positioning groove 201 in the first direction X away from the first fixing mechanism 500, and the second pressing mechanism 400 slides along the second positioning groove 202 in the second direction Y away from the second fixing mechanism 600, so as to facilitate the unloading of the plate from the worktable 200.

[0026] In related technologies, when the cutting tool of a drilling machine drills a hole near the positioning pin 22 of the positioning mechanism 100 on the plate to be drilled, the pressure foot above the cutting tool may press against the positioning pin 22, which may cause the cutting tool to break. Therefore, this application provides a positioning mechanism 100, which can reduce the possibility that the pressure foot of the drilling machine may press against the positioning pin 22 used to position the plate when drilling, thereby reducing the risk of cutting tool breakage and improving the stability and production efficiency of the drilling operation.

[0027] The specific structure of the positioning mechanism 100 provided in the embodiments of this application is described in detail below with reference to the accompanying drawings.

[0028] Figure 2 This is a three-dimensional structural diagram of the positioning mechanism provided in an embodiment of this application along an angle. Figure 3 for Figure 2 The diagram shows a three-dimensional view of the positioning mechanism from another angle.

[0029] See Figure 2 and Figure 3 This application provides a positioning mechanism 100, including a support base 1, a positioning component 2, and a toggle component 4.

[0030] The support base 1 has a support plane 10, and the support base 1 has a first end 11 and a second end 12 opposite to each other along its own length direction. The support plane 10 is disposed below the worktable 200 and is connected by fasteners.

[0031] The positioning component 2 is disposed at the first end 11 of the support base 1. The positioning component 2 includes a fixed base 21 and a positioning pin 22 inserted into the fixed base 21. The fixed base 21 is movably connected to the support base 1. The positioning pin 22 is located above the worktable 200 and is used to abut against the edge of the plate to be drilled and to perform coarse positioning of the plate to be drilled.

[0032] The actuating element 4 is movably connected between the support base 1 and the fixed base 21; wherein, when the actuating element 4 rotates relative to the support base 1, it can drive the positioning pin 22 to rise or fall relative to the support plane 10 along a first tilt angle.

[0033] In this embodiment, the movement of the actuating element 4 can be achieved manually or automatically. Specifically, the actuating element 4 rotates clockwise relative to the support base 1, while simultaneously sliding upward relative to the fixed base 21, thereby causing the positioning pin 22 to rise relative to the support plane 10 at a first inclination angle. At this time, the positioning pin 22 can be used to position the edge of the plate to be drilled for coarse positioning. The actuating element 4 rotates counterclockwise relative to the support base 1, while simultaneously sliding downward relative to the fixed base 21, thereby causing the positioning pin 22 to descend relative to the support plane 10 at a first inclination angle. In this way, when the tool drills a hole near the positioning pin 22 in the plate to be drilled, the positioning pin 22 can descend along the first inclination angle as the drilling depth increases, without interfering with the pressure foot. This reduces the possibility that the pressure foot will press on the positioning pin 22 used to position the plate when drilling, thereby reducing the risk of tool breakage and improving the stability and production efficiency of the drilling operation.

[0034] Figure 4 for Figure 2 The diagram shown illustrates the positioning mechanism as viewed from one direction. Figure 5 for Figure 4 The positioning mechanism shown is a cross-sectional view along direction AA. Figure 6 for Figure 2 The diagram shown is a structural schematic of the positioning mechanism viewed from another direction. Figure 7 for Figure 6 The positioning mechanism shown is a cross-sectional view along direction BB.

[0035] In some embodiments, the positioning mechanism 100 further includes a rotating shaft 5, and the support base 1 is provided with a first through groove 13 along the direction perpendicular to the support plane 10. The two ends of the rotating shaft 5 are connected to the wall of the first through groove 13, and the support base 1 is rotatably connected to the first connector 41 of the actuating member 4 through the rotating shaft 5.

[0036] like Figure 1 , Figure 2 and Figure 7As shown, the first through groove 13 includes a first groove and a second groove that are interconnected. The width of the second groove is greater than the width of the first groove. Both ends of the rotating shaft 5 are connected to the wall of the first groove and are secured between the wall of the first groove and one end of the rotating shaft 5 by a shaft retaining ring to restrict the axial movement of the rotating shaft 5. The actuating member 4 is rotatably connected to the rotating shaft 5. The second groove corresponds to the position of the hole to be drilled on the plate to be drilled, so that the tool can be accommodated when drilling.

[0037] In some embodiments, the first end 11 of the support base 1 is provided with a second through groove 14, and either the inner wall of the second through groove 14 or the outer wall of the fixed base 21 is provided with a guide groove 141. The other one of the inner wall of the second through groove 14 and the outer wall of the fixed base 21 is provided with a guide post 211 that cooperates with the guide groove 141. The axial direction of the guide post 211 forms a first tilt angle with the plane where the support plane 10 is located.

[0038] like Figure 7 As shown, guide grooves 141 are respectively provided on both sides of the inner wall of the second through groove 14 of the support base 1, and guide posts 211 that cooperate with the guide grooves 141 are provided on the outer wall of the fixed base 21. The axial direction of the guide post 211 forms a first inclination angle α with the plane where the support plane 10 is located, so that the fixed base 21 drives the positioning pin 22 to rise or fall relative to the support plane 10 along the first inclination angle α.

[0039] It is understandable that guide posts 211 can also be provided on both sides of the inner wall of the second through groove 14 of the support base 1, and guide grooves 141 that cooperate with the guide posts 211 are provided on the outer wall of the fixed base 21.

[0040] In some embodiments, the first tilt angle α satisfies the following condition: 70°≤α≤80°. The magnitude of the first tilt angle α is related to the lifting height of the positioning pin 22 and the distance between the pressure foot and the plate to be drilled, and depends on the specific application scenario.

[0041] In some embodiments, the fixing base 21 is provided with a downwardly inclined groove 212 in a direction away from the positioning pin 22, and the fixing base 21 is slidably connected to the actuating member 4 through the groove 212. Figure 5 As shown, the actuating element 4 is slidably connected to the slide groove 212 of the fixed seat 21, so as to drive the fixed seat 21 and the positioning pin 22 to rise or fall relative to the support plane 10 at a first tilt angle α.

[0042] In some embodiments, the length direction of the slide 212 forms a second tilt angle with respect to the plane where the support plane 10 is located, and the second tilt angle is complementary to the first tilt angle.

[0043] like Figure 5As shown, the second tilt angle is β, and α + β = 90°. Optionally, 10° ≤ β ≤ 20°. This configuration allows the positioning mechanism 100 to have a compact structure and occupy less space.

[0044] In some embodiments, the fixing base 21 includes a first base body 21a and a second base body 21b that are separately arranged and connected to each other, a positioning pin 22 is inserted into the first base body 21a, and a sliding groove 212 is provided in the second base body 21b.

[0045] like Figure 1 As shown, the first base 21a and the second base 21b are stacked. A positioning pin 22 is inserted into the first base 21a. The second base 21b has a sliding groove 212. The first base 21a also has two fixing holes located on both sides of the positioning pin 22. The second base 21b has two corresponding threaded holes. Fasteners pass through the fixing holes and connect to the threaded holes to connect the first base 21a and the second base 21b into one unit. The separate arrangement of the first base 21a and the second base 21b reduces the difficulty of machining the sliding groove 212 of the fixing base 21, thereby reducing manufacturing costs.

[0046] In some embodiments, the positioning mechanism 100 further includes a first driving device 3 disposed at the second end 12 of the support base 1, and the actuating member 4 includes a first connector 41, a second connector 42 and a third connector 43 connected to each other. The first connector 41 is rotatably connected to the support base 1, the second connector 42 is connected to the output shaft 31 of the first driving device 3, and the third connector 43 is slidably connected to the fixed base 21.

[0047] Optionally, the first drive device 3 can be any one of a cylinder, an electric push rod, and a hydraulic cylinder. The output shaft 31 of the first drive device 3 can drive the second connector 42 of the actuating member 4 to perform reciprocating linear motion, so that the actuating member 4 can automatically rotate around the support base 1, thereby driving the positioning pin 22 to rise or fall relative to the support plane 10 at a first tilt angle, thereby improving work efficiency.

[0048] In some embodiments, the second end 12 of the support base 1 is provided with an inclined surface 15 on the side facing the first driving device 3, the first driving device 3 is fixedly connected to the inclined surface 15, and the output shaft 31 of the first driving device 3 is arranged parallel to the inclined surface 15.

[0049] like Figure 5As shown, the third connector 43 of the actuating element 4 is slidably connected to the groove 212 of the fixed base 21, and the length direction of the groove 212 forms a second inclination angle β with respect to the plane where the supporting plane 10 is located. In order to make the rotation of the actuating element 4 around the rotating shaft 5 smooth, the first driving device 3 is fixedly connected to the inclined surface 15 of the second end 12 of the support base 1, so that the output shaft 31 of the first driving device 3 can extend and retract in a direction parallel to the inclined surface 15. Thus, the second connector 42 of the actuating element 4 is connected to the output shaft 31 to drive the rotation of the actuating element 4 around the rotating shaft 5, thereby driving the positioning pin 22 to rise or fall relative to the supporting plane 10 at the first inclination angle, and the overall structure is more compact.

[0050] Figure 8 This is a schematic diagram of the drilling system provided in an embodiment of this application. Figure 9 for Figure 8 The diagram shows the structure of the drilling equipment in the first state of the drilling system. Figure 10 for Figure 8 The diagram shows the structure of the drilling equipment in the second state of the drilling system.

[0051] See Figure 8 This application provides a drilling system, including a drilling platform 1000 and a drilling device 2000.

[0052] The drilling platform 1000 is used to support and position the plate P to be drilled. The drilling equipment 2000 is arranged opposite to the drilling platform 1000. The drilling equipment 2000 includes a spindle 2001, a chip suction cover 2002 sleeved on the spindle, a cutter 2003 connected to one end of the spindle 2001, and a pressure foot 2004 disposed between the chip suction cover 2002 and the cutter 2003. When the cutter 2003 drills a hole in the plate P near the positioning pin 22 of the drilling platform 1000, the positioning pin 22 can descend in a direction away from the pressure foot 2004 as the drilling depth of the cutter 2003 increases, thereby reducing the possibility of the pressure foot 2004 pressing on the positioning pin 22.

[0053] like Figure 8 As shown, when the cutting tool 2003 of the drilling equipment 2000 has not yet begun drilling at the position of the locating pin 22 adjacent to the drilling platform 1000 of the plate to be drilled, a portion of the pressure foot 2004 abuts against the locating pin 22. Figure 9 As shown, in the first state, the drilling equipment 2000, with the cutting tool 2003, begins drilling at the position of the locating pin 22 adjacent to the drilling platform 1000 on the plate to be drilled, and the locating pin 22 and the pressure foot 2004 do not interfere with each other. Figure 10 As shown, when the drilling equipment 2000 is in the second state, the pressure foot 2004 collides with the positioning pin 22.

[0054] In this embodiment, two situations may occur when the drilling equipment 2000 drills a hole in the plate P to be drilled: one is that before the positioning pin 22 descends along the first tilt angle α, the pressure foot 2004 will press against the positioning pin 22, such as... Figure 8 As shown, after the locating pin 22 descends along the first tilt angle α, the pressure foot 2004 no longer presses against the locating pin 22. At this time, the pressure foot 2004 no longer tilts due to the locating pin 22, as... Figure 9 As shown; another scenario is that after the locating pin 22 descends along the first tilt angle α, the presser foot 2004 will still press against the locating pin 22, but... Figure 8 Compared to before the positioning pin 22 descends along the first tilt angle α, the tilt angle when the pressure foot 2004 presses against the positioning pin 22 will be significantly reduced, such as... Figure 10 As shown, both scenarios reduce the risk of tool 2003 breaking during drilling, improving the stability of drilling operations and thus indirectly increasing production efficiency.

[0055] According to the positioning mechanism 100, drilling platform 1000 and drilling system provided in this application, by setting the positioning mechanism 100 and the plate to be drilled on the drilling platform 1000, the positioning mechanism 100 includes a support base 1, a positioning component 2 and a toggle member 4. The positioning component 2 includes a fixed base 21 and a positioning pin 22 inserted into the fixed base 21. The fixed base 21 is movably connected to the support base 1. The positioning pin 22 is used to abut against the edge of the plate to be drilled. The toggle member 4 is movably connected between the support base 1 and the fixed base 21. When the toggle member 4 rotates relative to the support base 1, it can drive the positioning pin 22 to rise or fall relative to the support plane 10 along a first tilt angle. In this way, when the cutting tool 2003 drills a hole near the locating pin 22 on the plate to be drilled, the locating pin 22 can descend in a direction away from the pressure foot 2004 as the drilling depth increases, thereby reducing the possibility of the pressure foot 2004 pressing on the locating pin 22, thus reducing the risk of breakage of the cutting tool 2003 and improving the stability and production efficiency of the drilling operation.
