[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-347865 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, there has been a demand for higher precision in drilling, which requires highly accurate adjustment of the center distance between spindles. However, the printed circuit board processing machine described in Patent Document 1 adjusts the center distance between a pair of spindles using a large-diameter feed screw mechanism, and it is not possible to adjust the center distance with high precision.

[0005] Therefore, an object of the present invention is to provide a processing device that can accurately adjust the center distance between a first rotary tool and a second rotary tool. [Means for solving the problem]

[0006] According to one aspect of the present invention, a processing apparatus includes a mounting table on which a workpiece is placed and which is movable in a first direction; a movable member which is movable in a second direction perpendicular to the first direction; a first processing unit which has a first spindle which rotatably supports a first rotary tool capable of drilling a hole in the workpiece and is supported by the movable member; a second spindle which rotatably supports a second rotary tool capable of drilling a hole in the workpiece; and a support device which supports the second spindle so that its position can be adjusted in the first direction and the second direction and is supported by the movable member, wherein the support device has a fixed part fixed to the movable member, a support part which is supported relative to the fixed part so as to be rotatable around a first rotation axis extending along a third direction perpendicular to the first direction and the second direction and which supports the second spindle, and a first operating part which rotates the support part around the first rotation axis. [Effects of the Invention]

[0007] According to the present invention, the center distance between the first rotary tool and the second rotary tool can be adjusted with high precision. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] A drilling device 2 according to an embodiment of the present invention will be described below with reference to the drawings. In the following description, for example, the X direction, Y direction, and Z direction shown in Fig. 1 are directions perpendicular to one another, and the drilling device 2 can drill holes in the Z direction on a printed circuit board 4. The X direction, Y direction, and Z direction constitute a first direction, a second direction, and a third direction, respectively.

[0010] [Overall configuration of drilling equipment] As shown in FIG. 1 , a drilling device 2 as a processing device according to this embodiment includes a device base 1 and a processing table 3 that can be moved in the X direction relative to the device base 1 by a drive mechanism (not shown). A printed circuit board 4 as a workpiece is placed on the processing table 3 as a mounting table. The drilling device 2 also includes a portal column 5 that is installed on the device base 1 and positioned to straddle the processing table 3, and a cross slide 6 as a moving member that can be moved in the Y direction relative to the portal column 5 by a drive mechanism (not shown). The drilling device 2 also includes a first processing unit S1 and a second processing unit S2 that are provided on the cross slide 6, a linear motor 13 that synchronously moves the first processing unit S1 and the second processing unit S2 in the Z direction, and a control unit 10 that controls the drilling device 2.

[0011] The control unit 10 includes a CPU as a calculation device, a ROM for storing various programs, and a RAM used as a work area for the CPU. The drilling device 2 positions the first processing unit S1 and the second processing unit S2 relative to the printed circuit board 4 placed on the processing table 3 by moving the processing table 3 in the X direction and the cross slide 6 in the Y direction. The linear motor 13 then drives the drills of the first processing unit S1 and the second processing unit S2, synchronously descending in the Z direction, and the first processing unit S1 and the second processing unit S2 drill holes in the printed circuit board 4. In this way, holes can be drilled simultaneously in the printed circuit board 4 with a single drilling process, improving the processing speed and productivity of the printed circuit board. Furthermore, compared to providing two drilling devices with only one processing unit per processing table, the installation space for the drilling device 2 can be saved and costs can be reduced. In this embodiment, two holes are simultaneously drilled in one printed circuit board 4 by the first processing unit S1 and the second processing unit S2, but this is not limiting. For example, two printed circuit boards may be drilled by the first processing unit S1 and the second processing unit S2, respectively.

[0012] The first processing unit S1 has a holder 27 fixed to the cross slide 6, a spindle 7 as a first spindle supported by the holder 27, and a drill 8 as a first rotary tool detachably and rotatably supported by the spindle 7. The drill 8 is rotationally driven by a spindle motor (not shown), and can drill holes in the printed circuit board 4 by being lowered in the Z direction by the drive of the linear motor 13. In this way, the spindle 7 and the drill 8 cannot move relative to the cross slide 6 in the X and Y directions.

[0013] The second processing unit S2 has a fixing mechanism 15 connected to the linear motor 13 and supported by the cross slide 6, and a spindle 7 that is detachably attached to the fixing mechanism 15 via a connecting rod 14. The second processing unit S2 also has a drill 8 serving as a second rotary tool that is detachably and rotatably supported on the spindle 7. The second processing unit S2 also has a support device 9 that supports the spindle 7 serving as the second spindle via a sleeve 16. As will be described later, the support device 9 supports the spindle 7 so that its position can be adjusted in the X and Y directions, and is supported by the cross slide 6 via the connecting rod 14 and the fixing mechanism 15.

[0014] The connecting rod 14 is connected to the spindle 7 and has a flange that faces the output shaft of the linear motor 13. The fixing mechanism 15 can connect (fix) or release the flange to the output shaft of the linear motor 13. In other words, the fixing mechanism 15 can transition between a connected state in which the output shaft of the linear motor 13 and the flange are connected and the spindle 7 can move in the Z direction, and an released state in which the output shaft of the linear motor 13 and the flange are separated from each other.

[0015] [Support device] Next, the support device 9 will be described with reference to Figures 2(a) to 4. By operating the support device 9, the user can move the spindle 7 of the second processing unit S2 in the X direction and Y direction and adjust its position. When operating the support device 9, the fixing mechanism 15 is in an open state.

[0016] As shown in Figures 2(a) to 3, the support device 9 has a lower sleeve 9c, a middle sleeve 9b as a first support member, an upper sleeve 9a as a second support member, a first adjusting screw 31 as a first operating part, and a second adjusting screw 32 as a second operating part. The lower sleeve 9c as a fixed part is fixed to the cross slide 6 and is formed with a substantially rectangular cross section. The lower sleeve 9c also has a substantially circular lower hole 11c into which the sleeve 16 and spindle 7 are inserted. This provides a gap between the lower sleeve 9c and the sleeve 16 that allows the middle sleeve 9b and the upper sleeve 9a to rotate to a certain extent.

[0017] The middle sleeve 9b is supported rotatably about a first rotation shaft 12b relative to the lower sleeve 9c and is formed in a substantially cylindrical shape. A substantially circular middle hole 11b is formed in the middle sleeve 9b, into which the sleeve 16 and the spindle 7 are inserted. This provides a gap between the middle sleeve 9b and the sleeve 16 that allows the middle sleeve 9b and the upper sleeve 9a to rotate to some extent.

[0018] The upper sleeve 9a is supported by the middle sleeve 9b so as to be rotatable about a second rotation shaft 12a and has a generally cylindrical shape. The second rotation shaft 12a is located at a different position from the first rotation shaft 12b. The first rotation shaft 12b and the second rotation shaft 12a each extend along the Z direction and are parallel to each other. The upper sleeve 9a has a generally circular upper step hole 11a into which the sleeve 16 and spindle 7 are inserted. The sleeve 16 is supported by the upper step hole 11a and supports the spindle 7 movably in the Z direction via a bearing 17. Thus, the lower sleeve 9c, the middle sleeve 9b, and the upper sleeve 9a each have a lower step hole 11c, a middle step hole 11b, and an upper step hole 11a, respectively, into which the spindle 7 is inserted. The middle sleeve 9b, the upper sleeve 9a, the second rotation shaft 12a, and the second adjustment screw 32 form a support portion 40. The support portion 40 rotates about the first rotation shaft 12b relative to the lower sleeve 9c, and supports the sleeve 16 and the spindle 7.

[0019] The middle sleeve 9b rotates about the first rotation shaft 12b when the first adjustment screw 31 is operated by the user. More specifically, the first adjustment screw 31 moves back and forth in the X direction when operated by the user. As a result, the first adjustment screw 31 presses the middle sleeve 9b in the X direction, causing the middle sleeve 9b to rotate about the first rotation shaft 12b. For example, as shown in FIG. 4(b), the axial center of the spindle 7, i.e., the axial center of the drill 8 attached to the spindle 7, can be moved in the X direction by a distance β from point P3 to point P4.

[0020] The upper sleeve 9a rotates about the second rotation shaft 12a when the second adjustment screw 32 is operated by the user. More specifically, the second adjustment screw 32 moves forward and backward in the Y direction when operated by the user. As a result, the second adjustment screw 32 presses the upper sleeve 9a in the Y direction, causing the upper sleeve 9a to rotate about the second rotation shaft 12a. For example, as shown in FIG. 4(a), the axial center of the spindle 7, i.e., the axial center of the drill 8 attached to the spindle 7, can be moved a distance α in the Y direction from point P1 to point P2.

[0021] The order in which the positions of the middle sleeve 9b and the upper sleeve 9a are adjusted is not particularly limited. For example, the position of the axial center of the spindle 7 may be confirmed by gradually advancing and retracting the first adjustment screw 31 and the second adjustment screw 32. In this way, the axial center position of the spindle 7 can be easily adjusted by simply operating two adjustment screws, improving operability. Furthermore, because the middle sleeve 9b and the upper sleeve 9a rotate around the first rotation shaft 12b and the second rotation shaft 12a, adjustment of the position of the spindle 7 is intuitive and easy to understand, and the position of the spindle 7 can be adjusted accurately. This allows the center distance between the drill 8 of the first processing unit S1 and the drill 8 of the second processing unit S2 to be adjusted accurately.

[0022] Furthermore, the first adjusting screw 31 is disposed on the opposite side of the spindle 7 from the first rotating shaft 12b in the Y direction, and the second adjusting screw 32 is disposed on the opposite side of the spindle 7 from the second rotating shaft 12a in the X direction. This makes the amount of movement of the axial center of the spindle 7 (e.g., distances α and β) smaller than the amount of advancement and retreat of the first adjusting screw 31 and the second adjusting screw 32. This makes it possible to precisely adjust the position of the axial center of the spindle 7 of the second processing section S2, and to precisely adjust the center-to-center distance between the two drills 8.

[0023] Furthermore, the lower sleeve 9c, the middle sleeve 9b, and the upper sleeve 9a that make up the support device 9 are arranged side by side in the Z direction, and the middle sleeve 9b and the upper sleeve 9a rotate in the X and Y directions. This allows the support device 9 to be configured compactly and simply, thereby reducing costs.

[0024] <Summary> The processing device (2) according to this embodiment is a mounting table (3) on which a workpiece (4) is placed and which is movable in a first direction (X); a moving member (6) movable in a second direction (Y) perpendicular to the first direction (X); a first processing unit (S1) that rotatably supports a first rotary tool (8) capable of drilling a hole in a workpiece (4) and has a first spindle (7) supported by the moving member (6); a second processing unit (S2) including a second spindle (7) that rotatably supports a second rotary tool (8) that can drill a hole in a workpiece (4), and a support device (9) that supports the second spindle (7) so that its position can be adjusted in the first direction (X) and the second direction (Y) and is supported by the moving member (6), The support device (9) is characterized by having a fixed part (9c) fixed to the moving member (6), a support part (40) supported by the fixed part (9c) so as to be rotatable around a first rotation axis (12b) extending along a third direction (Z) perpendicular to the first direction (X) and the second direction (Y) and supporting the second spindle (7), and a first operating part (31) that rotates the support part (40) around the first rotation axis (12b).

[0025] The support part 40 that supports the spindle 7 of the second processing part S2 rotates around the first rotation axis 12b by operating the first adjustment screw 31. In this way, the position of the axial center of the spindle 7 can be adjusted simply by operating the first adjustment screw 31, which provides good operability and allows the center distance between the two drills 8 to be adjusted with high precision. Furthermore, the support device 9 can be configured compactly and simply, reducing costs.

[0026] In the above-described embodiment, the drill 8 is attached to the spindle 7, but the present invention is not limited to this. For example, other rotary tools such as a router may be attached to the spindle 7.

[0027] In the above-described embodiment, the middle sleeve 9b and the upper sleeve 9a are configured to be rotatable about the first rotation shaft 12b and the second rotation shaft 12a, respectively, but this is not limiting. For example, the upper sleeve 9a may be formed integrally with the middle sleeve 9b and may not be configured to rotate about the second rotation shaft 12a. In other words, the support device 9 may be configured to adjust the position of the spindle 7 using a sleeve that rotates about one rotation shaft (for example, the first rotation shaft 12b).

[0028] In the above-described embodiment, two separate printed circuit boards are drilled by the two processing units S1 and S2, but this is not limiting. For example, one printed circuit board may be drilled by the two processing units S1 and S2.

[0029] In the above-described embodiment, the middle sleeve 9b and the upper sleeve 9a are rotated by the first adjusting screw 31 and the second adjusting screw 32, respectively, but this is not limiting. For example, at least one of the first adjusting screw 31 and the second adjusting screw 32 may be replaced with a piezo actuator, a solenoid, or the like. Furthermore, the middle sleeve 9b and the upper sleeve 9a may be biased toward the first adjusting screw 31 and the second adjusting screw 32 by a biasing member such as a spring (not shown).

[0030] In the above-described embodiment, the upper sleeve 9a, the middle sleeve 9b, and the lower sleeve 9c are arranged in this order from top to bottom in the Z direction, but this is not limiting. For example, the lower sleeve 9c may be arranged above the upper sleeve 9a.

[0031] In the above-described embodiment, the first adjusting screw 31 is disposed on the opposite side of the spindle 7 from the first rotating shaft 12b in the Y direction, and the second adjusting screw 32 is disposed on the opposite side of the spindle 7 from the second rotating shaft 12a in the X direction, but this is not limiting. For example, the first adjusting screw 31 may be disposed between the first rotating shaft 12b and the spindle 7 in the Y direction. For example, the second adjusting screw 32 may be disposed between the second rotating shaft 12a and the spindle 7 in the X direction. [Explanation of symbols]
