Description

Technical Field

[0001] The invention relates to the technical field of circuit board processing, and in particular to a circuit board air-floating shaft vibration drilling machine and an operating method thereof. Background Art

[0002] In the modern electronics industry, printed circuit boards (PCBs) are key components of electronic devices, and their manufacturing accuracy and efficiency directly affect the performance and reliability of the entire device. Drilling is the core link in the circuit board manufacturing process, and its quality directly determines the electrical connection performance and assembly accuracy of the circuit board. However, the circuit board drilling machine in the prior art has a series of technical problems that need to be solved in the drilling process.

[0003] Specifically, when drilling holes in printed circuit boards, the drill needle of a circuit board drilling machine usually produces debris in the holes formed by drilling. For example, as the drilling depth of the drilling machine gradually increases, if these debris are not discharged from the hole, they will remain and accumulate in the hole, which will not only easily affect the accuracy of the drilling depth of the drilling machine, but also easily cause slight differences in the depths of multiple holes, thereby affecting the performance of subsequent conductive via manufacturing. In addition, the debris remaining in the hole will hinder the drill needle from continuing to drill. For example, if these debris continue to remain and accumulate in the hole while the drilling machine continues to drill, the drilled hole is likely to have rough edges, and these rough edges will reduce the performance of the printed circuit board.

[0004] In summary, in the circuit board drilling machine in the prior art, it is difficult to discharge the debris during the drilling process, which makes it difficult to ensure the precise control of the drilling depth and the smoothness of the hole edge. Summary of the invention

[0012] Among them, the first magnetic part has a second permanent magnet, the second magnetic part has a second annular electromagnetic coil, and the second permanent magnet surrounds the second annular electromagnetic coil, and the second annular electromagnetic coil is arranged in the second hollow space of the first magnetic part, and the floating shaft and the magnetic induction component change the magnetic pole of the second magnetic part through the second annular electromagnetic coil so that the magnetic pole between the second magnetic part and the second permanent magnet changes to drive the floating shaft to reciprocate in the second direction.

[0013] Among them, the first magnetic part has a third permanent magnet, the second magnetic part has a third annular electromagnetic coil, and the third permanent magnet is arranged on one side of the third annular electromagnetic coil, the floating rotating shaft and the magnetic induction component change the magnetic pole of the second magnetic part through the third annular electromagnetic coil so that the magnetic pole between the second magnetic part and the third permanent magnet changes to drive the floating rotating shaft to reciprocate in the second direction.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0033] The first embodiment of the present application is:

[0034] See also Figure 1 to Figure 5 ,in Figure 1 It is a schematic cross-sectional structural diagram of the first embodiment of the present invention. Figure 2 It is a schematic cross-sectional view of the local structure of the first embodiment of the present invention.

Figure 4 It is a cross-sectional schematic diagram of the floating shaft of the first embodiment of the present invention when it moves in another direction. Figure 5 It is a schematic diagram of the first permanent magnet and the controller of the present invention.

[0035] The present invention provides a circuit board air-floating shaft vibration drilling machine, comprising an air-floating component 110, a floating rotating shaft 120 and a magnetic induction component 130, wherein the air-floating component 110 has a movable space 111 and a first air-floating bearing 112 and a second air-floating bearing 114 arranged around the movable space 111, wherein the second air-floating bearing 114 is located on one side of the first air-floating bearing 112, wherein the movable space 111 has a first distance A1 in a first direction D1, and wherein the movable space 111 has a second distance A2 in a second direction D2, wherein the second direction D2 is perpendicular to the first direction D1;

[0036] The floating shaft 120 is arranged in the movable space 111, and one end of the floating shaft 120 has a first magnetic part 121. The floating shaft 120 has a first bearing part 122 arranged along the first direction D1 and a second bearing part 124 arranged along the second direction D2. The second bearing part 124 is connected to the first bearing part 122. The first bearing part 122 has a bearing width B1 in the first direction D1, and the second bearing part 124 has a bearing thickness B2 in the second direction D2. The bearing width B1 is smaller than the first distance A1, and the bearing thickness B2 is smaller than the second distance A2; so that the floating bearing can float in the movable space 111 through the first air bearing 112 and the second air bearing 114, and a drill needle 126 is arranged on the floating bearing;

[0037] The magnetic induction component 130 is disposed on one side of the floating shaft 120, and the magnetic induction component 130 has a second magnetic part 131. The floating shaft 120 drives the drill 126 on the floating shaft 120 to reciprocate in the second direction D2 by changing the magnetic poles between the first magnetic part 121 and the second magnetic part 131 in the magnetic induction component 130.

[0038] According to this specific embodiment, the second air bearing 114 of the air floating assembly 110 is disposed below the first air bearing 112. The movable space 111 inside the air floating assembly 110 is hollow and has a first distance A1 in the first direction D1 and a second distance A2 in the second direction D2 perpendicular to the first direction D1;

[0039] The first air bearing 112 and the second air bearing 114 of the air floating assembly 110 are used to allow air to enter the movable space 111, so that the floating shaft 120 floats in the movable space 111 and does not contact the upper half 113 and the lower half 115 of the first air bearing 112 and the second air bearing 114;

[0040] In addition, the rotor portion 128 of the floating shaft 120 can rotate with the stator portion 116 of the air floating assembly 110, so that the floating shaft 120 rotates clockwise or counterclockwise to perform drilling.

[0041] Specifically, the bearing width B1 is smaller than the first distance A1 of the movable space 111, and the bearing thickness B2 is smaller than the second distance A2 of the movable space 111, so that the floating shaft 120 can be slightly moved up, down, left, and right in the movable space 111 through the first air bearing 112 and the second air bearing 114, thereby improving the mobility of the floating shaft 120 when drilling.

[0042] In addition, the floating shaft 120 and the magnetic induction component 130 can drive the drill needle 126 of the floating shaft 120 to reciprocate in the second direction D2 (i.e., the vertical direction) by changing the magnetic poles between the first magnetic part 121 and the second magnetic part 131. That is, the drill needle 126 of the floating shaft 120 can perform slight up and down reciprocating motion when drilling, so that when the drill needle 126 drills the printed circuit board, the debris can be taken out of the hole, which can improve the accuracy of the circuit board air-floating shaft vibration drilling machine 100 for the drilling depth requirement. In addition, when the drill needle 126 of the floating shaft 120 reciprocates up and down to take out the debris in the hole, it can also perform the chip cutting action at the same time, so that the drilled hole has a smooth edge to improve the situation where the debris remains in the hole during drilling and produces a rough edge, which can improve the effect performance of the printed circuit board after drilling.

[0043] Among them, the first magnetic part 121 has a first permanent magnet 123A, and the second magnetic part 131 has a first annular electromagnetic coil 132A. The first annular electromagnetic coil 132A surrounds the first permanent magnet 123A, and the first permanent magnet 123A is arranged in the first hollow space C1 of the second magnetic part 131. The floating shaft 120 and the magnetic induction component 130 change the magnetic pole of the second magnetic part 131 through the first annular electromagnetic coil 132A so that the magnetic pole between the second magnetic part 131 and the first permanent magnet 123A changes to drive the floating shaft 120 to reciprocate in the second direction D2.

[0044] According to this specific embodiment, when the adjacent end of the first permanent magnet 123A is the N pole and the first annular electromagnetic coil 132A is energized so that the second magnetic portion 131 is the N pole, a repulsive force is generated to move the floating shaft 120 away from the magnetic induction component 130, that is, move downward.

[0045] On the other hand, when the adjacent end of the first permanent magnet 123A is the N pole and the first annular electromagnetic coil 132A is energized so that the second magnetic part 131 is the S pole, an attractive force is generated to allow the floating shaft 120 to move closer to the magnetic induction component 130, that is, move upward, so that the floating shaft 120 can move back and forth up and down along the second direction D2 through the action of the first annular electromagnetic coil 132A.

[0046] Please refer to Figure 3 and Figure 4 ,At Figure 3 and Figure 4 In the embodiment, the second air bearing 114 has an upper section 113 and a lower section 115. When the floating shaft 120 moves away from the magnetic induction component 130 (i.e., when a repulsive force is generated), a first spacing P1 between a lower surface 127 of the second bearing portion 124 of the floating shaft 120 and the lower section 115 of the second air bearing 114 is smaller than a second spacing P2 between an upper surface 125 of the second bearing portion 124 of the floating shaft 120 and the upper section 113 of the second air bearing 114.

[0047] In addition, when the floating shaft 120 moves toward the magnetic induction component 130 (i.e., when an attractive force is generated), the third spacing P3P3 between the lower surface 127 of the second bearing portion 124 of the floating shaft 120 and the lower half 115 of the second air bearing 114 is greater than the fourth spacing P4 between the upper surface 125 of the second bearing portion 124 of the floating shaft 120 and the upper half 113 of the second air bearing 114. For example, the first spacing P1, the second spacing P2, the third spacing P3, and the fourth spacing P4 are all less than 50 mm, that is, the floating shaft 120 can move slightly up and down along the second direction D2.

[0048] For the second embodiment, please refer to Figure 6 , Figure 6 It is a schematic cross-sectional view of the partial structure of the floating shaft and the magnetic induction component of the second embodiment of the present invention.

[0049] Different from the first embodiment, the first magnetic part 121 has a second permanent magnet 123B, the second magnetic part 131 has a second annular electromagnetic coil 132B, and the second permanent magnet 123B surrounds the second annular electromagnetic coil 132B, and the second annular electromagnetic coil 132B is arranged in the second hollow space C2 of the first magnetic part 121, and the floating shaft 120 and the magnetic induction component 130 change the magnetic pole of the second magnetic part 131 through the second annular electromagnetic coil 132B so that the magnetic pole between the second magnetic part 131 and the second permanent magnet 123B changes to drive the floating shaft 120 to reciprocate in the second direction D2.

[0050] For the third embodiment, please refer to Figure 7 , Figure 7 It is a schematic cross-sectional view of the local structure of the floating shaft and the magnetic induction component of the third embodiment of the present invention.

[0051] Different from the first embodiment, the first magnetic part 121 has a third permanent magnet 123C, the second magnetic part 131 has a third annular electromagnetic coil 132C, and the third permanent magnet 123C is arranged on one side of the third annular electromagnetic coil 132C, and the floating shaft 120 and the magnetic induction component 130 change the magnetic pole of the second magnetic part 131 through the third annular electromagnetic coil 132C so that the magnetic pole between the second magnetic part 131 and the third permanent magnet 123C changes to drive the floating shaft 120 to move back and forth in the second direction D2.

[0052] See also Figure 8 , Figure 8 It is a flow chart of the operating method of the circuit board air-floating shaft vibration drilling machine of the present invention.

[0053] The present invention also provides an operating method of a circuit board air-floating shaft vibration drilling machine, which is applied to the circuit board air-floating shaft vibration drilling machine as described above.

[0054] The steps include:

[0055] The circuit board air-floating shaft vibration drilling machine 100 is started, and the drill needle 126 on the circuit board air-floating shaft vibration drilling machine 100 performs drilling processing;

[0056] At the same time, the magnetic poles between the second magnetic part 131 and the first magnetic part 121 are changed to drive the drill needle 126 of the floating shaft 120 to reciprocate in the second direction D2, thereby causing the drill needle 126 to reciprocate in the drilled hole;

[0057] The drill needle 126 moves back and forth in the drilled hole while removing debris from the hole.

[0058] The operating method of the circuit board air-floating shaft vibration drilling machine 100 of the present invention is as follows:

[0059] First, the floating shaft 120 can be set in the movable space 111 of the air floating component 110, wherein the air floating component 110 has the first air floating bearing 112 set around the movable space 111 and the second air floating bearing 114 set around the movable space 111 and on one side of the first air floating bearing 112, and the movable space 111 has a first distance A1 in the first direction D1, and the movable space 111 has a second distance A2 in the second direction D2 perpendicular to the first direction D1.

[0060] Next, the floating shaft 120 can float in the movable space 111 through the first air bearing 112 and the second air bearing 114, wherein the floating shaft 120 has the first bearing portion 122 arranged along the first direction D1 and the second bearing portion 124 connected to the first bearing portion 122 and arranged along the second direction D2, the first bearing portion 122 has a bearing width B1 in the first direction D1, the second bearing portion 124 has a bearing thickness B2 in the second direction D2, the bearing width B1 is smaller than the first distance A1 and the bearing thickness B2 is smaller than the second distance A2.

[0061] Then, the magnetic polarity between the second magnetic portion 131 of the magnetic induction component 130 and the first magnetic portion 121 of the floating shaft 120 may be changed to drive the drill needle 126 of the floating shaft 120 to reciprocate in the second direction D2.

[0062] Please refer to Figure 8 , Figure 8 A block diagram of the first annular electromagnetic coil 132A and a controller according to an embodiment of the present disclosure is shown. The controller is electrically connected to the first annular electromagnetic coil 132A, and the controller can control the current flow direction generated by the first annular electromagnetic coil 132A, thereby generating an attraction or repulsion force.

[0063] Specifically, when the floating shaft 120 moves away from the magnetic induction component 130 (i.e., when a repulsive force is generated), a first spacing P1 between the lower surface 127 of the second bearing portion 124 of the floating shaft 120 and the lower half 115 of the second air bearing 114 is smaller than a second spacing P2 between the upper surface 125 of the second bearing portion 124 of the floating shaft 120 and the upper half 113 of the second air bearing 114. In addition, when the floating shaft 120 moves closer to the magnetic induction component 130 (i.e., when an attractive force is generated), a third spacing P3 between the lower surface 127 of the second bearing portion 124 of the floating shaft 120 and the lower half 115 of the second air bearing 114 is larger than a fourth spacing P4 between the upper surface 125 of the second bearing portion 124 of the floating shaft 120 and the upper half 113 of the second air bearing 114.

[0064] To summarize, the bearing width B1 of the floating shaft 120 of the circuit board air-floating shaft vibration drilling machine 100 is smaller than the first distance A1 of the movable space 111, and the bearing thickness B2 of the floating shaft 120 is smaller than the second distance A2 of the movable space 111, so that the floating shaft 120 can be slightly moved up, down, left and right in the movable space 111 through the first air-floating bearing 112 and the second air-floating bearing 114, which can improve the mobility of the floating shaft 120 when drilling.

[0065] In addition, the floating shaft 120 and the magnetic induction component 130 can drive the drill 126 of the floating shaft 120 to reciprocate in the second direction D2 (i.e., the vertical direction) by changing the magnetic poles between the first magnetic part 121 and the second magnetic part 131. That is to say, the drill 126 of the floating shaft 120 can perform slight up and down reciprocating motion when drilling through the change of the magnetic poles. Therefore, when the drill 126 drills the printed circuit board, the debris can be brought out of the hole, which can improve the accuracy of the drilling depth requirement of the circuit board air-floating shaft vibration drilling machine 100.

[0066] In addition, when the drill needle 126 of the floating shaft 120 reciprocates up and down to remove the debris in the hole, it can also perform the chip cutting action at the same time, so that the drilled hole has a smooth edge to improve the situation where the debris remains in the hole during drilling and produces a rough edge, which can improve the performance of the printed circuit board after drilling.

[0067] Using a circuit board air-floating shaft vibration drilling machine and an operation method thereof of the present invention, firstly, the circuit board air-floating shaft vibration drilling machine 100 is started, and the drill needle 126 on the circuit board air-floating shaft vibration drilling machine 100 performs drilling processing; at the same time, the magnetic poles between the second magnetic part 131 and the first magnetic part 121 are changed to drive the drill needle 126 of the floating shaft 120 to reciprocate in the second direction D2, thereby causing the drill needle 126 to reciprocate in the drilled hole; while the drill needle 126 reciprocates in the drilled hole, it brings out debris from the hole, so that the drilled hole has a smooth edge to improve the situation where debris remains in the hole during drilling and produces a rough edge, which can improve the performance of the printed circuit board after drilling. When the floating shaft 120 moves away from the magnetic induction component 130, the The first spacing P1 between the lower surface 127 of the second bearing portion 124 and the lower half 115 of the second air bearing 114 is smaller than the second spacing P2 between the upper surface 125 of the second bearing portion 124 and the upper half 113 of the second air bearing 114; when the floating shaft 120 moves toward the magnetic induction component 130, the third spacing P3 between the lower surface 127 of the second bearing portion 124 and the lower half 115 of the second air bearing 114 is larger than the fourth spacing P4 between the upper surface 125 of the second bearing portion 124 and the upper half 113 of the second air bearing 114, thereby solving the technical problem in the prior art that it is difficult to discharge debris during the drilling process of the circuit board drilling machine, which makes it difficult to ensure the precise control of the drilling depth and the smoothness of the hole edge.

[0068] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
