Description

  The present invention relates to a modular in-line micro-drill bit re-polishing apparatus, and more particularly, a micro-drill cleaned to obtain high re-polishing quality after cleaning the micro-drill bit used through the cleaning module to remove foreign substances. Re-grinding is performed by pressing and fixing the bit, and the position of the ring connected to the outer peripheral surface of the micro-drill bit that has been re-polished can be automatically adjusted according to the length of the re-polished micro-drill bit. The present invention relates to a module type in-line micro drill bit re-polishing apparatus composed of a ring setting module.

  In general, a processing technology for holes and appearance of a printed circuit board (PCB) substrate is required to have precision in micro units. In order to satisfy such a demand, a tool such as a micro drill bit, an end mill bit, and a router bit for performing hole processing and slot processing on a circuit board is also required. Usually, among micro bits, a micro drill bit is a tool for machining a hole for mounting a chip on a circuit board, and a diameter of 0.05 mm to 3 mm forms a main axis.

  When the hole processing through the micro drill bit as described above is repeated, wear due to friction, heat, etc. occurs and frequent replacement is unavoidable. As shown in (P1) of FIG. The problem of being caught between cutting blades was frequent.

  Therefore, there is a problem with labor cost and low productivity according to performing re-polishing after the operator cleans the micro drill bit.

  Further, conventionally, most of the worn and damaged micro drills as shown in (P2) of FIG. 1 are discarded, which increases the waste of micro drills made of expensive materials and the cost of parts. The increase in cost has acted as a factor to increase the price for supplying the PCB substrate, and has become a great obstacle to the improvement of price competitiveness.

  In order to solve such problems, an apparatus and a method have been developed that allow a microdrill worn by the hole processing of the PCB substrate to be re-polished through a polishing apparatus so that it can be reused. Even with the fine tremors that occur during polishing, there is a problem in that the quality of micro drill bits having a very small diameter deteriorates and defects often occur.

  In addition, the existing re-grinding machine removes foreign substances generated at the cutting tip of the micro drill bit in the process of quality inspection after re-polishing, but the polishing cleaning pad for this purpose only rotates. However, there is a problem that the disposal rate is high and resources are wasted.

  Further, as shown in FIG. 1 (P3), the micro drill bit has a ring 200 installed to adjust the drilling depth, and when the micro drill bit is re-polished, a cutting blade can be seen from one side of the ring 200. The position of the ring 200 had to be adjusted by changing the length of the micro drill bit protruding in the direction, but the operator adjusted the position of the ring according to the length that was manually re-polished. However, there is a problem that it is difficult to adjust the position because the length variation due to polishing is fine.

  Further, it may be composed of only one cleaning inspection unit 1002, or may be composed of a plurality of cleaning inspection units 1002, as shown in FIG. One cleaning inspection unit 1002 inspects the micro drill bit before cleaning, and the other one cleaning inspection unit 1002 inspects the micro drill bit after cleaning.

  First, FIG. 10 illustrates a method for determining a reusable micro drill bit through a simple length. As shown in (a) to (e), the cleaning transfer ( Among the plurality of micro drill bits held and transferred by 1003) in FIG. 9, a micro drill bit that does not reach the virtual reference line 10A through any one of an optical sensor, a laser, an ultrasonic wave, and a camera. Come to detect.

  Further, the position of the micro drill bit having a length shorter than the preset virtual reference line 10A, such as (b) and (c), is stored in the cleaning inspection unit 1002 or the control means (not shown). .

  Further, FIG. 10 does not judge a simple length, and was photographed after photographing a plurality of micro drill bits located in one row as shown in (f) to (j) using a camera. Two virtual tangents 11A are formed at the end of each micro drill bit photographed through the image, and a virtual detection angle 11B formed by the two virtual tangents 11A and an intersection 11C of the two virtual tangents 11B are measured. Will come to do.

  Further, the position of the micro drill bit such that the virtual detection angle 11B is larger than a predetermined value set in advance (h) or the intersection 11C does not reach the virtual reference line 10A (g) is the position of the cleaning inspection unit 1002 or It is stored in control means (not shown).

  More specifically, after storing (storing) in what cleaning column 1002 or control means (not shown) what column is located in what column, the cleaning classification unit (1006 in FIG. 9) described below. Failed microdrill bits that cannot be reused in the stored (stored) position are classified separately.

  The detection of the defective micro drill bit as described above is performed before cleaning, because the cleaning module does not clean one micro drill bit at a time, but grips and cleans a plurality of micro drill bits. Even if the drill bit is not removed in advance, the cleaning speed is high, and the inspection time is shortened by advancing the inspection while gripping and transferring the plurality of micro drill bits.

  That is, without confirming one micro drill bit before cleaning one by one, after confirming a plurality of micro drill bits being transferred at once, proceed with cleaning, and classify only defective micro drill bits individually, A series of processes can be achieved more efficiently in a short time.

  12 to 15 illustrate the cleaning transfer of the cleaning module. As shown in FIG. 12, a plurality of cleaning transfers 1003 installed so as to correspond to both sides pass through the center of the cleaning device 1005. After passing, the cleaning transfer on one side returns to the 12A direction, and the cleaning transfer on the other side returns to the 12B direction.

  In addition, although the movement path of the central part overlaps, a plurality of cleaning transfers 1003 collide on the movement path of the central part due to different passing orders (sequentially transferred along the central part), Or it will not overlap.

  The means for gripping the micro drill bit is a bit capture 1004, and the cleaning transfer 1003 moves the bit capture 1004 to the cleaning device 1005 side.

  The cleaning transfer 1003 includes a cleaning transfer guide rail 1031 supported by the cleaning transfer column 1030, a cleaning transfer horizontal moving member 1032 that moves horizontally along the cleaning transfer guide rail 1031 by driving the cleaning transfer driving means 1036, and the cleaning A cleaning transfer horizontal cylinder 1033 installed at the top of the transfer horizontal moving member 1032 and a cleaning transfer vertical cylinder 1034 installed at the rod end of the cleaning transfer horizontal cylinder 1033 and operated by hydraulic pressure to move the bit capture 1004 up and down. Including.

  That is, the cleaning transfer horizontal moving member 1032 moves horizontally in the Y-axis direction along the cleaning transfer guide rail 1031 so that the bit capture 1004 moves back and forth between the conveyor of the transfer module and the cleaning device. 1034 moves the bit capture 1004 up and down in the Z-axis direction, and the cleaning transfer horizontal cylinder 1033 prevents the two bit captures 1004 installed in the two cleaning transfers 1003 installed facing each other from colliding with each other. Means for horizontally moving in the X-axis direction.

  The bit capture 1004 is a means for actually grasping the micro drill bit and moving it to the cleaning device 1005. A large number of micro drill bits can be grasped by one bit capture 1004. The micro drill bit can be cleaned.

  The bit capture 1004 includes a bit capture upper block 1041 that moves horizontally and vertically by the cleaning transfer 1003, a bit capture capture block 1042 installed at an end of a bit capture guide shaft 1044 fixed to the bit capture upper block, A plurality of bit capture pushing pins 1043 that can vertically move in the Z-axis direction along the bit capture guide shaft 1044 and have one end fitted in each bit capture hole formed in the bit capture capture block 1042. , And a spring 1045 that allows the bit capture pushing pin 1043 to be elastically supported toward the bit capture upper block 1041. Constructed.

  The bit capture upper block 1041 is fixed to the rod of the cleaning transfer vertical cylinder 1034 of the cleaning transfer 1003, and bit capture guide shafts 1044 are installed at both ends.

  A number of bit capture pushing pins 1043 that can be raised and lowered along the bit capture guide shaft 1044 and are elastically supported by a spring 1045 are provided.

  As described above, a large number of bit capture pushing pins 1043 that can be moved up and down along the bit capture guide shaft 1044 are elastically supported by the spring 1045. The bit capture hole 1042 is located in a form in which a predetermined length is inserted into each bit capture hole, but is pressed more than the elastic force of the spring 1045 that elastically supports a number of bit capture push pins 1043. 15, as shown in FIG. 15, a large number of bit capture pushing pins 1043 may pass through the respective bit capture holes formed in the bit capture capture block 1042. It is inserted deeper.

  If the bit capture capture block 1042 moves downward by operating the cleaning transfer vertical cylinder 1034 with the bit capture 1004 moved to the tray loaded with the micro drill bit to be cleaned through the above-described configuration, the bottom surface of the tray is placed on the tray. In this state, the micro drill bit protruding from the tray by a predetermined length is fitted into the bit capture / capture block 1042 by a predetermined length.

  Further, the micro drill bit fitted and transferred to the bit capture / capture block 1042 as described above and cleaned is detached from the bit capture / capture block 1042 by the operation of the capture pressing unit 1300.

  More specifically, in the capture pressing portion 1300 for lowering the micro drill bit held by the bit capture 1005, the capture pressing plate 1302 fixed to the rod of the capture pressing cylinder 1301 presses the bit capturing pushing pin 1043 from above. Accordingly, as shown in FIG. 15, a plurality of bit capture pushing pins 1043 are inserted through or deeper into the respective bit capture holes formed in the bit capture capture block 1042, and the bit capture of the bit capture capture block 1042 is performed. The micro drill bit fitted and fixed in the hole is detached by the bit capture pushing pin 1043 and loaded on the tray.

  As described above, when the cleaned micro drill bit is filled in the tray, the tray is moved by the operation of the transfer module 4000 and transferred to the cleaning classification unit 1006.

  Further, the cleaning device 1005 is provided as a means for cleaning the micro drill bit that has been moved while being held by the bit capture 1004.

  As shown in FIG. 16 or FIG. 17, the cleaning device 1005 is for cleaning water spray nozzles 1511 for spraying high-pressure cleaning water onto the micro drill bit, and for drying the moisture of the micro drill bit cleaned with the cleaning water. An air injection nozzle 1521 for injecting high-pressure dry air is included.

  The washing water jet nozzle 1511 is connected to a water supply pipe 1513 through a manifold 1512 so that washing water jetted through the washing water jet nozzle 1511 can be simultaneously supplied to each washing water jet nozzle 1511. The air injection nozzle 1521 is connected to the air supply pipe 1523 through the manifold 1522 so that the air injected through 1521 can be simultaneously supplied to each air injection nozzle 1521.

  On the other hand, as described above, the cleaning inspection unit 1002 or the control means (not shown) stores the diameter of the micro drill bit and the state of the foreign material, but the cleaning water depends on the stored state of the micro drill bit. The spray pressure of the cleaning water sprayed through the spray nozzle 1511 and the spray pressure of the air sprayed through the air spray nozzle 1521 are adjusted. That is, the more the foreign substance is attached to the micro drill bit, the stronger the jet pressure of the cleaning water and the jet pressure of the air, so that the contaminants attached to the micro drill bit can be more effectively removed. In consideration of the diameter of the micro drill bit, the injection pressure is adjusted within a range in which the micro drill bit is not damaged.

  Further, a drain pipe 1540 for discharging the cleaning water discharged after cleaning the micro drill bit is further installed at the lower part of the cleaning device 1005, so that the discharged sewage is collected in one place. I was able to throw it away.

In addition, a cover 1530 is installed so that the cleaning water sprayed through the cleaning water spray nozzle 1511 can be prevented from splashing outside, and the cover 1530 has a bit capture 1004 in which a micro drill bit is gripped. A bit passage groove 1531 is formed to the extent that it can pass.

  Of the micro drill bits that have been cleaned by the cleaning device 1005 while being transferred by the cleaning transfer 1003 as described above, the micro drill bit that has been determined to be defective or non-reusable by the cleaning inspection unit 1002 (hereinafter, damaged) The tray loaded with the micro-drill bit is fixed by the tray fixing unit (4103 in FIG. 9), and then separately classified by the cleaning classification unit 1006.

  18 to 20 illustrate a cleaning classification unit 1006 of the cleaning apparatus capable of discharging a damaged micro drill bit according to the present invention. The cleaning classification unit 1006 is detected by the cleaning inspection unit 1002. The cleaning classification transfer 1601 for gripping and transferring the damaged micro drill bit whose loaded position is stored in the control means, and the damaged micro drill bit for gripping and transferring the cleaning classification transfer 1601 And a cleaning stacking section 1602 on which a plurality of disposal trays 1A for storing the waste is placed.

  The cleaning classification transfer 1601 includes a cleaning classification transfer clamp 1621 for gripping a damaged micro drill bit among a plurality of micro drill bits loaded on the tray 1, and the cleaning classification transfer clamp 1621 as a Z-axis. A cleaning classification transfer Z-axis transfer cylinder 1622 for moving in the direction and a cleaning classification transfer support 1624 for transferring the cleaning classification transfer clamp 1621 in the Y-axis direction are configured.

  Further, the cleaning stacking unit 1602 has a cleaning stacking cartridge 1654 on which a plurality of disposal trays 1A for mounting damaged microdrill bits is mounted, and a cleaning stacking plate to which the cleaning stacking cartridge 1654 is removed and attached. 1653, and a cleaning stacking servo motor 1651 for moving the cleaning stacking plate 1653 along the cleaning stacking LM guide 1652 by a predetermined distance in the X-axis direction.

  The cleaning stack cartridge 1654 is mounted on the cleaning stack plate 1653, but it can be removed and attached, and can further include the cleaning stack handle 1656 so that the operator can easily replace it. .

  More specifically, the position detected by the cleaning inspection unit and loaded in the tray 1 transferred through the transfer module 4000 (the loaded tray and the position of the row and column in the tray) is stored in the control means. When the cleaning classification transfer clamp 1621 grips the micro drill bit using the cleaning classification transfer clamp 1621 and the cleaning classification transfer clamp 1621 completes the gripping, the micro drill bit is lifted by the operation of the cleaning classification transfer Z-axis transfer cylinder 1622.

  When the ascent is completed, the cleaning classification transfer clamp 1621 and the cleaning classification transfer Z-axis transfer cylinder 1622 are transferred along the cleaning classification transfer support base 1624 in the Y-axis direction by the rotation of the cleaning classification transfer Y-axis transfer servo motor 1623, The broken microdrill bit being gripped is loaded on the cleaning stacking unit 1602.

  Further, in the method of loading damaged microdrill bits on the disposal tray 1A mounted on the cleaning stacking unit 1602 in FIG. 19, the stacking is performed sequentially from one side column of the first row.

  That is, they are sequentially stacked one by one in rows and columns.

  More specifically, the micro drill bit damaged by the cleaning classification transfer 1601 is transferred to the cleaning stacking section 1602, and the cleaning classification transfer 1601 can only be transferred in the Y-axis or the Z-axis. , 16B2, 16B3,...) And the row (16A1, 16A2,...), The microdrill bit damaged in another row out of the predetermined position (42A) of the disposal tray 1A. It is a structure that cannot load.

  As a result, instead of the cleaning classification transfer 1601, the cleaning stacking section 1602 is moved in the X-axis direction by a predetermined distance, and the cleaning classification transfer 1601 is broken into a plurality of rows (16A1, 16A2,...). A bit can be loaded.

  In the X-axis direction transfer of the cleaning stacking unit 1602 as described above, the cleaning stacking plate 1653 is cleaned by the cleaning stacking LM by rotating the cleaning stacking belt 1655 combined with the classified cleaning stacking plate 1653 by a predetermined amount. A predetermined distance is transferred along the guide 1652 in the X-axis direction.

  Further, it is preferable that the transfer amount of the classified cleaning stacking plate 1653 by the cleaning stacking servo motor 1651 is transported by a distance between one row.

  For example, after the first column 16B1 of the first row 16A1 to the last column of the first row 16A1 are completely packed (loaded) through the cleaning classification transfer 62, the second row 16A1 is placed at a predetermined position (42A). Thus, the classified cleaning stacking plate 1653 is moved in the X-axis direction.

  In addition, when the transfer is completed, the cleaning classification transfer 62 is damaged microdrill bit that could not pass the test result from the first column 16B1 of the second row 16A2 to the last column of the second row 16A2 of the waste tray 1A. Will come to load.

  As described above, after the cleaning and the classification of the broken microdrill bit are completed through the cleaning module (1000 in FIG. 2), they are loaded on the tray supplied to the polishing module (2000 in FIG. 2) through the transfer module 4000. The cleaned micro drill bit is subjected to a re-polishing process through the polishing module.

  FIG. 21 illustrates a polishing module of the modular in-line micro drill bit re-polishing apparatus according to the present invention. The cleaned micro-drill bit to be re-polished from the tray 1 transferred through the transfer module 4000 is shown in FIG. After receiving and fixing sequentially one by one, one of the polishing rotating unit 2003 that rotates horizontally at a predetermined angle and the micro-drill bit to be re-polished that is fixed to the polishing rotating unit 2003 is re-polished.

  For example, a module type in-line micro drill bit re-polishing apparatus in which the polishing clamping unit 2005 is deleted may be used. In other words, the polishing rotating unit 2003, a position adjusting unit (not shown, described below), a polishing unit 2004, a polishing cleaning unit 2009, a polishing supply transfer 2061, a polishing classification unit 2006, and a polishing discharge transfer 2062 may be included. it can.

  However, as a preferred embodiment, in order to re-polish the micro drill bit with high quality, it is preferable to include all the above-described components.

  The micro-drill bits to be re-polished loaded on the tray 1 through the combination of the above-described configuration are re-polished one by one and then loaded on another tray and discharged.

  Further, as described above, two (4104, 4105) of the plurality of tray fixing portions of the transfer module 4000 can supply the micro drill bit to the polishing module or collect the re-ground micro drill bit. Are located at the lower part of the supply transfer 2061 and the lower part of the discharge transfer 2062, respectively.

22 to 24 are diagrams for explaining the operation of the polishing supply transfer in the modular in-line micro drill bit re-polishing apparatus according to the present invention. The polishing supply transfer 2061 includes a tray fixing portion (see FIG. 21). 4104) one of the chucks 2031 of the polishing rotating unit 2003, each of the micro-drill bits scheduled to be re-polished from the tray 1 loaded with the micro-drill bit scheduled to be re-polished through the cleaning module. To fulfill the role of supplying to.

  The polishing supply transfer 2061 includes a polishing supply transfer clamp 2611, a polishing supply transfer X-axis polishing rotating unit 2612, a polishing supply transfer Z-axis transfer table 2613, a polishing supply transfer Z-axis transfer cylinder 2614, and a polishing supply transfer Y-axis transfer table 2615. , And a polishing supply transfer support base 2616.

  More specifically, the polishing supply transfer clamp 2611 of the polishing supply transfer 2061 can be rotated in the X-axis by the polishing supply transfer X-axis polishing rotating unit 2612 and can be narrowed or unrolled.

  That is, the polishing supply transfer X-axis polishing rotating unit 2612 can perform two operations of rotation and pressing (squeezing or spreading).

  Accordingly, the polishing supply transfer clamp 2611 can grip one of the micro-drill bits to be re-polished loaded on the tray 1, and when the polishing supply transfer clamp 2611 completes the gripping, the polishing supply transfer clamp 2611 completes the gripping. The polishing supply transfer Z-axis transfer table 2613 to which the X-axis polishing rotating unit 2612 is fixed is raised by the operation of the polishing supply transfer Z-axis transfer cylinder 2614.

  When the rising is completed, the polishing supply transfer Y-axis transfer table 2615 to which the polishing supply transfer Z-axis transfer cylinder 2614 is fixed is transferred along the polishing supply transfer support table 2616 in the Y-axis direction.

  That is, the polishing supply transfer clamp 2611, the polishing supply transfer X-axis polishing rotating unit 2612, the polishing supply transfer Z-axis transfer table 2613, and the polishing supply transfer Z-axis transfer cylinder 2614 are all moved by the movement of the polishing supply transfer Y-axis transfer table 2615. It is transferred to the Y axis.

  In addition, the polishing supply transfer clamp 2611 transferred to the Y-axis is configured to insert the micro-drill bit to be re-polished held by the chuck 2031 of the polishing rotating unit in the Y-axis direction. 2611 can be rotated 90 degrees in the Y-axis direction from the -Z direction during the transfer.

  The micro-drill bits to be re-polished are supplied one by one to one of the chucks 2031 of the polishing rotating unit 2003 that rotates in the Z-axis direction by the method described above, and the polishing rotating unit 2003 rotates 90 degrees ( In the following description, the process is repeatedly performed by a method of supplying another micro drill bit to be repolished to another chuck.

FIGS. 25 to 27 illustrate a chuck of a polishing rotating unit and an opening / closing unit for opening and closing the chuck in the modular in-line micro drill bit re-polishing apparatus according to the present invention.
The polishing rotating unit (2003 in FIG. 22) includes a plurality of chucks 2031. The chuck 2031 includes a pressing ring 2311, a pressing clamp 2312, a pressing elastic body 2313, and a coupling 2314, and the pressing elastic body. 2313 causes the pressing ring 2311 to press the pressing clamp 2312 to grip (close) the micro drill bit 11.

  In addition, when the pressing ring 2311 is retracted by an external force (pressing), the pressing force by the pressing ring 2311 that has pressed the outer peripheral surface of the pressing clamp 2312 disappears, and the pressing clamp 2312 expands (opens) The micro drill bit 11 to be polished is released.

  Further, the chuck 2031 can be bent to some extent in the X-axis, Y-axis, and Z-axis directions by the coupling 2314, and this is used when the height of the chuck 2031 is precisely adjusted using the support bearing 2324. It is.

  That is, the height of the chuck 2031 can be adjusted by the height of the support bearing 2324 by the coupling 2314.

  An opening / closing part 2032 is used as means for pressing the pressing ring 2311 for fixing or releasing the micro drill bit 11 to be re-polished as described above.

  More specifically, the opening / closing part 2032 is opened and closed so that the micro drill bit 11 can be inserted or fixed (fixed or released) to the chuck 2031 by pressing the pressing ring 2311 by the operation of the opening / closing part 2032. And an open / close Z-axis transfer cylinder 2322 and an open / close Y-axis transfer cylinder 2323.

  The open / close plate 2321 has a semicircular groove at one end, and the diameter of the semicircular groove is smaller than the diameter of the pressing ring 2311 and larger than the diameter of the pressing clamp 2312.

  This is because only the pressing ring 2311 is pressed and opened without being in contact with the pressing clamp 2312.

  The open / close plate 2321 can be Z-axis transferred and Y-axis transferred by an open / close Z-axis transfer cylinder 2322 and an open / close Y-axis transfer cylinder 2323, and the open / close Z-axis transfer cylinder 2322 is used for height correction of the open / close plate 2321. The open / close Y-axis transfer cylinder 2323 is used to move the open / close plate 2321 in the Y-axis direction and press the pressing ring 2311.

  In other words, the open / close plate 2321 is moved in the Y-axis by the open / close Y-axis transfer cylinder 2323 to press the pressing ring 2311.

  FIG. 28 or FIG. 29 illustrates a polishing rotating unit of the modular in-line micro drill bit repolishing apparatus according to the present invention. The polishing rotating unit includes a chuck support 2034 to which a chuck 2031 is fixed, A rotation plate 2033 to which each chuck support portion 2034 is fixed, and a polishing rotation portion drive motor 2035 for rotating the rotation plate 2033 by a predetermined angle around the Z axis are configured.

  More specifically, the polishing rotation unit drive motor 2035 rotates at a predetermined angle depending on the number of the plurality of chuck support parts 2034, and 360 degrees is divided by the number of chuck support parts 2034 by an angle. It is preferable that the rotating plate 2033 is rotated by the polishing rotating unit driving motor 2035.

  For example, as shown in the figure, when the number of chuck support portions 2034 is four, it is preferable that the polishing rotating portion drive motor 2035 be rotated by 90 degrees by 360 divided by 4.

  This is because even if the chuck is rotated, it stops at the position where the chuck support before the other chuck support is rotated.

  The modular in-line micro-drill bit re-polishing apparatus according to the present invention can operate if it has one or more chuck support portions 2034. However, the micro-drill bit to be re-polished is supplied, re-polished, and re-polished. Having a minimum of four chuck supports 2034 to reduce the time loss and reduce production time (re-use) so that cleaning and inspection of the completed micro-drill bit and re-polishing of the completed micro-drill bit can be performed simultaneously. This is most preferable because the amount of polishing) can be increased.

  FIG. 30 or FIG. 31 illustrates a chuck support part of the polishing rotating part of the modular in-line micro drill bit repolishing apparatus according to the present invention, and supports a plurality of chucks positioned above the rotating plate 2033. The part 2034 differs only in the fixed position and direction, and all have the same configuration and form.

  Further, as shown in FIG. 30 or FIG. 31, among the plurality of chuck support portions directed in different directions, one chuck support portion 2034 directed in the X-axis direction will be described as a reference. It is as follows.

  A chuck rotation motor 2315 for rotating the chuck 2031 is positioned in the −X-axis direction (the rear surface of the chuck support), and the chuck rotation motor 2315 receives a micro drill bit fixed to the chuck 2031 through a coupling 2314. Rotate to an angle of.

  This is to align the cutting tip of the micro drill bit to be re-polished horizontally, and is a pre-process for re-polishing.

  More specifically, the chuck rotation motor 2315 is positioned on the rear surface of the first chuck support base 2341 capable of fine adjustment in the Y-axis direction at the upper part of the rotary plate 2033, and the first chuck support base 2341 is the first chuck support base 2341. The adjustment screw 2331 is rotated in the Y-axis direction by a predetermined distance (in proportion to the pitch and the rotation amount of the first chuck adjustment screw).

  A second chuck support 2342 is positioned on the upper surface of the first chuck support 2341. The second chuck support 2342 is rotated by a predetermined distance (second chuck) by the rotation of the second chuck adjusting screw 2332. It is transferred in the Y-axis direction from the top of the first chuck support 2341 (in proportion to the pitch and rotation amount of the adjusting screw).

  A third chuck support base 2343 is positioned on the front surface (X-axis direction) of the second chuck support base 2342, and the third chuck support base 2343 is rotated at a predetermined distance by the rotation of the third chuck adjustment screw 2333. Only in proportion to the pitch and the rotation amount of the third chuck adjusting screw from the front surface of the second chuck support 2342 in the Z-axis direction.

  A plurality of support bearings 2324 are located on the front surface (X-axis direction) of the third chuck support 2343, and support one side of the coupling to support the chuck 2031.

  Accordingly, the chuck 2031 can be finely adjusted in the Z-axis direction by the Z-axis direction transfer of the first chuck support base 2341 having a plurality of support bearings 2324 supporting the chuck 2031, and the support bearings can be adjusted. 2324, the chuck 2031 can be finely adjusted in the Y-axis direction by moving the second chuck support table 2342 to which the first chuck support table 2341 is fixed in the Y-axis direction.

  Further, the chuck support 2034 is moved in the Y-axis direction by the Y-axis direction transfer of the support bearing 2324, the first chuck support base 2341, the second chuck support base 2342, and the third chuck support base 2343 to which the chuck rotation motor 2315 is fixed. Fine adjustment of direction is possible.

  Further, the chuck 2031 can transmit the rotational force of the chuck rotation motor 2315 by the coupling 2314 while being finely adjusted in the Y-axis and Z-axis directions.

  That is, the rotational force can be transmitted by the coupling 2314 even if the rotation axis of the chuck 2031 and the rotation axis of the chuck rotation motor 2315 are not positioned on a straight line.

  As shown in FIG. 32, the polishing rotating unit 2003 having a plurality of chuck supporting units as described above is supplied with a micro drill bit to be re-polished from the polishing supply transfer 2061 and gripped using the chuck 2031. Rotating 90 degrees around the Z axis and proceeding with re-polishing through the polishing rotating unit 2004, and rotating 90 degrees and inspecting and cleaning the micro drill bit that has been re-polished through the polishing cleaning unit 2009 become.

  Further, when the polishing rotation unit 2004 rotates 90 degrees again, the polishing classification unit 2006 takes out (discharges) the microdrill bit that has been re-polished from the chuck 2031.

  Each process as described above is performed at the same time every 90 degrees of rotation by the polishing rotating unit 2003 having a plurality of chuck support parts.

  For example, while one chuck receives the supply of the micro drill bit to be re-polished from the polishing supply transfer 2061, the other chuck proceeds with re-polishing, and the other chuck proceeds with inspection and cleaning. Will proceed with the discharge operation.

  That is, a plurality of operations are performed at the same time, rotated 90 degrees, and then a plurality of operations are performed again.

  In more detail, the position adjustment transfer part which is equipped with the position adjustment fixing | fixed part 2072 which attaches | subjects the micro drill bit 11 to be re-polished to the front-end | tip, and can be thrown into a grinding | polishing part, and is comprised in the form which can be moved up and down. 2073, a position adjustment transfer screw 2075 that allows one side of the position adjustment transfer unit 2073 to be combined and moved up and down, and a side surface of the micro-drill bit 11 to be re-polished mounted on the position adjustment fixing unit 2072 The position adjustment data detection unit 2071 that collects information so that the micro drill bit 11 to be re-polished and positioned on the set reference line 71A and the position adjustment data detection unit 2071 receive the information. The above-mentioned position adjusting transfer screw 2075 is actuated so that the micro-drill bit 11 to be re-polished becomes a polishing part A micro-drill to be re-polished which is configured by a position adjusting servo motor 2076 to be positioned accurately so that the center of the micro-drill bit 11 to be re-polished can be accurately positioned to perform polishing. The present invention relates to a micro-drill bit automatic position adjusting device scheduled to be re-polished by a bit polishing apparatus.

  According to the automatic transfer device of the polishing apparatus for the microdrill bit 11 to be reground according to a preferred embodiment of the present invention, as shown in FIGS. 34 to 37, the microdrill bit 11 to be reground is supported from below. The position adjustment fixing portion 2072 that allows the position adjustment fixing portion 2072 to move up and down, the position adjustment transfer portion 2073 that moves the position adjustment fixing portion 2072 up and down, and the position adjustment transfer screw 2075 that is connected to the position adjustment transfer portion 2073 and moves in the Y-axis direction. , A position adjustment data detection unit 2071 for measuring the position of the micro drill bit 11 to be repolished mounted on the position adjustment fixing unit 2072, an illumination 2071B for making light incident on the position adjustment data detection unit 2071, and the position adjustment Through the information by the data detection unit 2071, the position adjustment transfer screw 207. Composed of the position regulation servomotor 2076 for controlling the operation.

  As shown in FIG. 35, the position adjustment fixing part 2072 can be mounted by inserting the micro drill bit 11 to be re-polished into the end part connected to the position adjustment transfer part 2073 at the lower part and connected to the upper part. The support block 2072A to be configured is formed.

  At this time, it is preferable that the position adjustment fixing portion 2072 is configured to be bent so that the upper portion is directed forward of the diagonal line so that the polishing device can be easily put into a polishing portion provided with a cutting tool.

  The position adjustment transfer unit 2073 is coupled in a vertically movable form on the position adjustment support base 2074 installed in the polishing apparatus in a vertical form and is transferred up and down by a position adjustment transfer screw 2075. At this time, the position adjustment support base 2074 is coupled to the position adjustment servo motor 2076, the position adjustment transfer screw 2075, and the position adjustment transfer unit 2073 at the same time so as to be positioned in front of the polishing unit provided in the polishing module. .

  The position adjustment transfer screw 2075 is coupled to one side of the position adjustment support base 2074 and is connected so that the position adjustment transfer unit 2073 can be moved up and down by switching the rotational movement to a linear movement.

  The position adjustment data detection unit 2071 is installed at a point parallel to the upper end of the position adjustment fixing unit 2072 coupled to the position adjustment transfer unit 2073, and the reference line 71A set itself and the position adjustment fixing unit. Whether or not the center portion of the micro-drill bit 11 to be re-polished to be mounted on the portion 2072 matches and the position of the micro-drill bit 11 to be re-polished can be grasped.

  Further, the illumination 2071B is positioned on the opposite side, and light is incident in the direction of the position adjustment data detection unit 2071. The light incident on the illumination 2071B is incident on the microdrill bit to be repolished, and then the position adjustment data is detected. It turns to the part 2071.

  Accordingly, the position adjustment data detection unit 2071 can analyze the outline of the shadow of the light incident by the illumination 2071B (vision recognition) and measure the height of the microdrill bit to be re-polished.

  The position adjustment servo motor 2076 is connected to the position adjustment transfer screw 2075 by a circuit, and controls the operation of the position adjustment transfer screw 2075 through information transferred by the position adjustment data detection unit 2071 to thereby adjust the position adjustment. The micro drill bit 11 to be re-polished mounted on the fixing portion 2072 is positioned accurately.

  Further, the position adjustment support base 2074 can be moved in the X-axis direction by a position adjustment screw 2074A at the lower part, and through this, fine adjustment in the X-axis direction is possible.

That is, not only the position adjustment support base 2074 but also the support block 2072A, the position adjustment fixing part 2072, the position adjustment transfer part 2073 , the position adjustment transfer screw 2075, and the position adjustment servo motor 2076 coupled to the position adjustment support base 2074 are simultaneously provided. It can be moved in the X-axis direction.

According to the position adjustment unit 2007 according to the above configuration, when the micro-drill bit 11 to be re-polished is mounted on the position adjustment fixing unit 2072 and put into the polishing apparatus, the position adjustment servo motor 2076 is moved to the position adjustment data detection unit 2071. The micro-drill bit to be re-polished mounted on the position-adjusting fixing part is controlled by controlling the operation of the position-adjusting transfer screw 2075 so that the center of the micro-drill bit 11 to be re-polished coincides with the set reference line 71A. For example, as shown in FIG. 37 (a), when the micro-drill bits 11, 11 ′ having different diameters are mounted, as shown in FIG. Due to the difference in diameter generated between the micro drill bit 11 ′ and the micro drill bit 11 to be re-polished thereafter, the my Position of the B drill bit 11 becomes eccentrically, in such a case, as shown in (b) of FIG. 37, the position adjusting servomotor errors of the central portion as described above were measured position adjusting data detection section 2071 By rotating 2076, the position adjusting / fixing portion 2072 is automatically moved to the same position as the previous reference line 71A so as to be adjusted to an accurate position. At this time, this operation is repeated until the position adjustment data detection unit 2071 and the center portion of the microdrill bit 11 to be repolished coincide with each other. Polishing (described below) proceeds.

  Therefore, the micro-drill bit 11 scheduled to be re-polished can be processed to an accurate dimension during the polishing process, and the occurrence of defects can be reduced through this process. It works to be able to significantly reduce time and improve productivity.

  In the above configuration, the position adjustment data detection unit 2071 is configured by a detection optical body, and the position adjustment transfer screw 2075 can be configured to be finely adjustable within an error of 0.005 mm by applying a ball screw. .

  As described above, the micro-drill bit 11 to be re-polished can be re-polished by being placed on the upper part of the position adjusting unit 2007. At this time, a certain pressure is applied from the upper part of the micro-drill bit to re-polish the micro-drill bit. As a method for fixing the micro drill bit and improving the re-polishing quality, the polishing clamping part 2005 can be used.

  38 to 41 illustrate a polishing clamping unit of the modular in-line micro drill bit re-polishing apparatus according to the present invention. The polishing clamping unit 2005 has the side surface of the micro-drill bit 11 to be re-polished on the upper side. The micro drill bit pressing clamp 2051 for pressing the micro drill bit and the clamp buffer 2052 for pressing the micro drill bit pressing clamp 2051 with a predetermined pressure, and the micro drill bit pressing clamp 2051 for the X and Y axes. , A clamp Z-axis adjustment screw 2053 for transferring in the Z-axis direction, a clamp Y-axis adjustment screw 2054, a clamp X-axis adjustment screw 2055, a first clamp transfer table 2056, a second clamp transfer table 2057, a third clamp transfer table 2058, And a clamp support 2059 It is made.

  Since the micro drill bit pressing clamp 2051 can move on the clamp support base 2059 in the X axis, the Y axis, and the Z axis through the above configuration, the form and size of the micro drill bit 11 to be re-polished. The pressure can be applied adaptively. The micro-drill bit 11 to be re-polished can be fixed by the micro-drill bit pressing clamp 2051 after being placed on the upper part of the position adjusting unit 2007.

  More specifically, a precision screw for transferring the micro drill bit pressing clamp 2051 to the X axis, the Y axis, and the Z axis can be implemented as a base. For example, when the micro drill bit pressing clamp 2051 is to be moved in the Z-axis direction, the clamp Z-axis adjusting screw 2053 that controls movement in the Z-axis direction is rotated to move the first clamp transfer table 2056 to move the micro-drill bit pressing clamp 2051. The drill bit pressing clamp 2051 can be moved in the Z-axis direction.

  Further, when the micro drill bit pressing clamp 2051 is to be moved in the X-axis direction, the clamp X-axis adjusting screw 2055 for controlling the movement in the X-axis direction is rotated to move the third clamp transfer table 2058 to thereby move the micro-drill bit pressing clamp 2051. The drill bit pressing clamp 2051 can be moved in the X-axis direction. In such a case, not only the micro drill bit pressing clamp 2051 but also the clamp Z-axis adjusting screw 2053 and the first clamp transfer table 2056 are simultaneously moved in the X-axis direction. It is transferred to.

  When the micro drill bit pressing clamp 2051 is to be moved in the Y-axis direction, the clamp Y-axis adjusting screw 2054 for controlling the movement in the Y-axis direction is rotated to move the second clamp transfer table 2057 to move the micro-drill bit pressing clamp 2051. The drill bit pressing clamp 2051 can be moved in the Y-axis direction. In the above case, not only the micro drill bit pressing clamp 2051, but also the clamp Z-axis adjusting screw 2053, the clamp X-axis adjusting screw 2055, the first ramp transfer The table 2056 and the third clamp transfer table 2058 are simultaneously transferred in the Y-axis direction.

  The micro drill bit pressing clamp 2051 as described above is connected through the first clamp transfer table 2056 and the clamp buffer portion 2052 to press the micro drill bit to be re-polished with a predetermined pressure. 2052 includes a clamp chuck 2052A, a clamp elastic body 2052B, and a ball bush 2052C.

  More specifically, the micro drill bit pressing clamp 2051 is coupled to the first clamp transfer table 2056 through the clamp buffer 2052 so that the micro drill bit 11 to be re-polished can be pressed with a constant pressure.

  The clamp buffer 2052 includes a clamp chuck 2052A so that the micro drill bit pressing clamp 2051 having different diameters can be replaced. The clamp chuck 2052A has a first clamp at one end at a predetermined depth. It is inserted into the transfer table 2056 and is connected by a ball bushing 2052C.

  That is, the clamp chuck 2052A is coupled by the ball bush 2052C so as to be movable in the Z-axis direction.

  The clamp chuck 2052A receives predetermined elasticity with respect to the Z-axis direction transfer by the clamp elastic body 2052B, and through this, the microdrill bit to be re-polished can be pressed with a predetermined pressure.

  Further, the micro drill bit pressing clamp 2051 can be pressed while maintaining a certain pressure by pressing the micro drill bit 11 to be re-polished using the clamp elastic body 2052B. Based on elastic force.

  In addition, the clamp support 2059 can be in the form of a cantilever, but in order to minimize tremor due to vibration, a form in the form of a cantilever is preferable.

  Through the above-described configuration, the micro-drill bit pressing clamp 2051 causes a tremor, lift, and pressing phenomenon when the micro-drill bit 11 to be re-polished placed on the position adjustment unit 2007 is pressed and re-polished. Can be prevented.

  Further, the microdrill bit pressing clamp 2051 can have a flat or curved surface (hereinafter referred to as a microdrill bit pressing surface) in contact with the microdrill bit 11 to be re-polished.

  That is, one end of the micro drill bit pressing clamp 2051 may be a flat surface or a curved surface.

  More specifically, as shown in FIG. 41 (a), the micro drill bit contact surface of the micro drill bit pressing clamp 2051 has a curved shape, or the micro drill bit as shown in FIG. 41 (b). The drill bit contact surface of the pressure clamp 2051 may have a planar shape.

  When the contact surface of the micro drill bit has a curved shape, the side surface of the micro drill bit is pressed to a larger area (a form in which the side surface of the drill bit is covered by a predetermined amount) to maximize the damage to the micro drill bit that can occur during pressing. The microdrill bit can be pressed and fixed while reducing the limit.

  Further, by making the drill bit positioned inside the curved surface of the drill bit pressing clamp 2051, the micro drill bit 11 to be re-polished is prevented from being pushed to the outside due to pressure during polishing, so that it is more effective. The microdrill bit 11 to be reground can be gripped.

  In addition, as described above, when the contact surface has a curved shape, it is preferable that the contact surface has a curved surface having a diameter larger than the diameter of the micro drill bit to be pressed so that a micro drill bit having another diameter can be pressed.

  This is because the micro drill bit cannot be correctly pressed when it has a diameter smaller than the diameter of the micro drill bit to be pressed.

  For example, the micro drill bit pressing clamp 2051 can form a curved surface having a diameter of 0.05 to 3 mm so as to press a general micro drill bit having a diameter of 0.05 to 3 mm, but a curved surface having a diameter of 3 mm or more. Are most preferred because all micro-drill bits having different diameters can be pressed.

  42 to 46 illustrate the polishing unit of the modular in-line micro drill bit repolishing apparatus according to the present invention. The polishing unit 2004 is moved in the X-axis direction by the polishing rotating unit 2003, and the cutting tip is horizontal. After the rotation, the micro drill bit to be re-polished and pressed and fixed by the position adjusting unit 2007 and the polishing clamping unit 2005 is re-polished.

  The polishing unit 2004 includes a polishing device 2041 for polishing the micro-drill bit 11 to be re-polished, a polishing X-axis servo motor 2042 for transferring the polishing device 2041, a polishing X-axis transfer table 2043, and a polishing Y-axis. A servo motor 2044 and a polishing Y-axis transfer table 2045 are included.

  Further, the polishing apparatus further includes a polishing rotating plate 2046 so that the polishing apparatus 2041, the polishing Y-axis servomotor 2044, and the polishing Y-axis transfer table 2045 can be rotated.

  More specifically, the polishing Y-axis transfer table 2045 on which the polishing apparatus 2041 is placed is placed on a polishing Y-axis LM guide (not shown) by a polishing Y-axis ball screw (not shown) rotated by a polishing Y-axis servomotor 2044. A polishing apparatus 2041, a polishing Y-axis transfer table 2045, a polishing Y-axis servo motor 2044, a polishing Y-axis ball screw (mounted on the upper part of the polishing rotating plate 2046) are possible. The polishing Y-axis LM guide (not shown) and the polishing Y-axis LM guide (not shown) can be rotated in the Z-axis by a polishing Z-axis servomotor (not shown).

  Also, the polishing rotating plate 2046 and the polishing device 2041 mounted on the upper portion, the polishing Y-axis transfer table 2045, the polishing Y-axis servo motor 2044, the polishing Y-axis ball screw (not shown), the polishing Y-axis LM guide (see FIG. The polishing X-axis transfer table 2043 on which a polishing Z-axis servomotor (not shown) is placed is mounted by a polishing X-axis ball screw (not shown) that is rotated by the polishing X-axis servomotor 2042. X-axis direction transfer is possible along a polishing X-axis LM guide (not shown).

  The polishing apparatus 2041 for polishing the micro-drill bit 11 to be re-polished through the above-described configuration not only performs X-axis and Y-axis transfer and Z-axis rotation, but also Z-axis rotation and X-axis and Y-axis transfer. In combination, diagonal (Y ′) transfer is also possible, as shown in FIG.

  For example, when the polishing Y-axis servomotor 2044 is rotated after being rotated to a predetermined angle using rotation in the Z-axis direction, the polishing Y-axis transfer table 2045 and the polishing apparatus are inclined in a direction inclined by a predetermined angle from the Y-axis direction. 2041 is transferred.

  As shown in FIG. 46, the polishing apparatus 2041 includes a plurality of grinders 2411 and 2412 having different inclinations, and a microdrill to be re-polished using different angles 2411A and 2412A. The bit is gradually processed.

  More specifically, the polishing apparatus 2041 includes a plurality of grinders 2411 and 2412 having inclinations 2411A and 2411A different from each other, so that the polishing apparatus 2041 is positioned at the end of the micro drill bit 11 to be re-polished. The cutting tip can be polished with different inclinations 2411A and 2412A.

  This is to improve the cutting efficiency (quality) of the micro drill bit (cutting tip), and the most preferable form is a curved form, but a micro drill bit having a very small diameter is re-polished to a curved form. Due to the difficulty, polishing is performed with different inclinations 2411A and 2412A.

  As described above, in order to re-polish the micro drill bit 11 to be re-polished with different inclinations 2411A and 2412A, the first grinder 2411 has a cutting tip of the micro-drill bit 11 to be re-polished with a predetermined inclination 2411A. Then, the second grinder 2412 grinds the cutting tip of the micro drill bit 11 to be repolished with a predetermined inclination 2412A.

  A series of processes as described above (polishing of the cutting tip by transfer of the polishing apparatus) is performed as follows.

  The first grinder 2411 and the second grinder 2412 of the polishing apparatus 2041 are transferred in the −X-axis direction by the rotation of the polishing X-axis servo motor 2042, and one side 111B of the cutting tip of the micro drill bit 11 to be re-polished is It comes into contact with the rotating first grinder 2411.

  In addition, one side 111B of the cutting tip of the micro drill bit 11 to be re-polished is brought into contact with the rotating second grinder 2412 while the polishing apparatus 2041 is being transferred by the rotation of the polishing Y-axis servo motor 2044, Re-polishing of one side 111B of the cutting tip of the micro-drill bit 11 to be polished is completed, and the polishing apparatus 2041 returns to the initial position by rotating the polishing X-axis servo motor 2042 and the polishing Y-axis servo motor 2044 in the opposite directions. Or, it is separated from the cutting tip of the micro drill bit 11 to be re-polished by a predetermined distance.

  In addition, the micro drill bit on which the polishing of the one side 11B of the cutting tip is completed is rotated 180 degrees by the rotation of the chuck rotating motor 2315 of the polishing rotating unit 2003 described above, and the other side 111A of the cutting tip is re-polished. Is carried out in the same manner as the polishing process of the one side 111B of the cutting tip.

  Further, a suction pipe 2047 for sucking dust generated at the time of re-polishing and a suction polishing rotating part 2048 for rotating the suction pipe 2047 to a predetermined angle may be further provided.

  Further, an injection nozzle 2049 for injecting high-pressure air in the direction of the suction pipe 2047 can be further provided. When the suction pipe 2047, the suction polishing rotating unit 2048, and the injection nozzle 2049 are further provided, dust scattering, It becomes possible to suppress dust from being attached to the micro drill bit during the re-polishing process.

  After detecting the position of the cutting tip of the micro-drill bit 11 to be re-polished that has been moved and fixed through the above-described configuration by the data detection unit 2071, the data for the detected position and the existing data input to the numerical controller The control unit (not shown) moves the polishing device 2041 to a predetermined position by using and advances the re-polishing, and is accurate through the transfer and rotation using the numerical control device (servo motor and ball screw). By allowing the micro drill bit to be re-polished at the position to be re-polished, it is possible to increase the process speed to achieve high productivity and to proceed with the re-polishing with high precision.

  The micro-drill bit 11 scheduled to be re-polished by a series of processes as described above will be described as a micro-drill bit 11 that has been re-polished after the re-polishing is completed.

  47 to 53 illustrate the polishing cleaning unit 2009 of the module type inline micro drill bit repolishing apparatus according to the present invention.

  As shown in FIG. 47, the micro-drill bit 11 that has been re-polished through the re-polishing process by the polishing unit is rotated by a predetermined angle by the polishing rotating unit 2003 and transferred toward the polishing cleaning unit 2009 to perform the cleaning operation. Polish quality inspection proceeds.

  Further, the micro-drill bit 11 to be re-polished held by the other chuck 2031 of the polishing rotating unit 2003 is polished by a predetermined angle by the polishing rotating unit 2003 at the place where the micro-drill bit 11 has been re-polished. Polishing is performed while the micro-drill bit 11 rotated in the direction in which re-polishing is completed and the polishing operation is performed by the polishing cleaning unit 2009.

  As shown in FIG. 48 or FIG. 49, the polishing cleaning unit 2009 is a polishing cleaning camera 2991 for photographing the cutting tip of the microdrill bit 11 that has been re-polished, and is positioned in front of the polishing cleaning camera 2991 and polishing. When the cleaning camera 2991 images the cutting tip, the polishing cleaning illumination 2992 for illuminating the light, the polishing cleaning pad 2993 for removing foreign substances located at the cutting tip of the microdrill bit 11 that has been re-polished, and the above polishing A cleaning X-axis transfer cylinder 2911 and a polishing cleaning pad 2993 for transferring any one of the cleaning illumination 2992 and the polishing cleaning pad 2993 so as to be positioned in front of the microdrill bit 11 which has been selectively re-polished. Is positioned in front of the re-polished micro drill bit 11 when the polishing cleaning pad 2 93 configured to include a polishing cleaning contact cylinder 2095 for causing the Y-axis-direction transfer.

  Further, the polishing cleaning pad 2993 of the modular in-line micro drill bit repolishing apparatus according to the present invention has a predetermined viscosity, and the polishing cleaning pad 2993 comes into contact with the end of the micro drill bit 11 that has been repolished. At this time, the foreign matter is adsorbed and removed by the polishing cleaning pad 2993 due to the viscosity.

  More specifically, in order to position one of the polishing cleaning pad 2993 and the polishing cleaning camera 2991 (or polishing cleaning illumination 2992) in front of the microdrill bit 11 that has been re-polished, the polishing cleaning pad 2993 is used. The polishing cleaning illumination 2992, the polishing cleaning camera 2991, and the polishing cleaning contact cylinder 2095 are positioned above the polishing cleaning first plate 2913, and the polishing cleaning first plate 2913 is connected to the polishing cleaning first X-axis LM guide 2912. Located at the top.

  Also, the polishing cleaning first plate 2913 on which the polishing cleaning pad 2993, the polishing cleaning illumination 2992, the polishing cleaning contact cylinder 2095, and the polishing cleaning camera 2991 are positioned is moved to the polishing cleaning first X-axis LM guide 2912 by the cleaning X-axis transfer cylinder 2911. Along the X axis.

  Further, the polishing cleaning pad 2993 and the polishing cleaning camera 2991 are positioned in front of the micro drill bit 11 that has been re-polished by the transfer in the X-axis direction by the cleaning X-axis transfer cylinder 2911.

  In one embodiment, when the micro-drill bit 11 that has been re-polished is positioned in the direction of the polishing-cleaning unit 2009, the polishing-cleaning pad 2993 is expanded by the extension of the polishing-cleaning contact cylinder 2095, and the micro-drill that has been re-polished. The foreign matter comes into contact with the cutting tip of the bit 11 and is removed.

  Further, after the cleaning is completed, the polishing cleaning camera 2991 is positioned instead of the polishing cleaning pad 2993 on the front surface of the micro drill bit 11 that has been re-polished through the −X-axis direction transfer by the cleaning X-axis transfer cylinder 2911. The polishing cleaning camera 2991 shoots the cutting tip of the microdrill bit 11 that has been re-polished while the polishing cleaning illumination 2992 irradiates light on the front surface of the micro drill bit 11 that has been re-polished, and a control unit (not shown). ) Will inspect the polishing quality based on the photographed image.

  Further, classification is performed by a polishing classification unit 2006 and a polishing discharge transfer 2062 described below according to the inspection result.

  On the other hand, the control unit (not shown) adjusts the processing amount of the micro drill bit to be processed later based on the photographed image. That is, the control unit compares the image of the cutting tip of the first micro-drill bit that has been re-polished with the reference image of the normal form, and determines the processing amount of the second micro-drill bit to be re-polished according to the difference in the image. To adjust.

  In other words, if the control unit determines that the first micro drill bit has been refined within the normal range to receive a pass judgment, it does not adjust the processing amount of the second micro drill bit to be processed thereafter, and the same processing amount as before. The polishing operation proceeds.

  However, if the controller determines that the first micro-drill bit has been refined out of the normal range, it analyzes the processed shape of the first micro-drill bit to determine how much additional machining is required. Come to consider.

  Thereafter, the second micro drill bit is subjected to the polishing operation by adding the machining amount corrected to the machining amount of the first micro drill bit. At this time, if the control unit determines that the second micro drill bit has been polished out of the normal range, the processed shape of the second micro drill bit is analyzed, and how much additional processing is required. Then, the third micro drill bit is reflected to reflect the machining amount, and the polishing operation is controlled to proceed.

If the processing amount of the micro drill bit is fixed, when the grinders 2411 and 2412 are worn, the micro drill bit cannot be processed into a desired shape. However, as described above, the method of analyzing the processing amount of the micro drill bit processed before and correcting the processing amount of the micro drill bit processed after that, the micro drill bit is miniaturized, and the grinder 2411 is used. Even if the 2412 surface is worn, the micro drill bit can be precisely machined by analyzing the machining result and subsequently performing the correction work.
A detailed description of the cleaning process after polishing the micro-drill bit 11 that has been re-polished as described above is as follows.

  The polishing cleaning pad 2993 described above is rotated by receiving a rotational force through the cleaning poly 2933 and the cleaning belt 2934 coupled to the rotation shaft of the polishing cleaning X-axis transfer servo motor 2921.

  In addition, when the polishing cleaning pad 2993 is in contact with the end portion of the microdrill bit 11 that has been re-polished while only rotating, as shown in FIG. The contact point 61A with which the microdrill bit 11 contacts and the moving path 62A thereof show a certain form, and by contacting only the moving path 62A, it is quickly worn (viscosity is lost). The polishing cleaning pad 2993 of the modular in-line micro drill bit re-polishing apparatus is transferred to the polishing cleaning pad 2993 that is in contact with the micro-drill bit 11 that has been re-polished as shown in FIG. The contact point 61A of the microdrill bit 11 which has been polished is not repeated in a circular shape having a constant diameter, and the sharpening is not repeated. Contact point 61A in the direction opposite to the transport direction is to move in the cleaning pad 2993.

  Further, as shown in FIG. 51, the polishing cleaning pad 2993 is simultaneously rotated while being transferred.

  More specifically, when the polishing cleaning pad 2993 is rotated clockwise while viewed in the right direction (when viewed from the front surface of the polishing cleaning pad), the contact point 61A is formed in the order of B1 to B5. .

  In addition to rotating in a predetermined distance, not only in the right direction, but rotating in translation, the geometric movement path 62B is formed, and the contact point 61A is continuously changed. A larger area can be used compared to the moving path 62A.

  Thus, by having various contact paths as compared with the fixed movement path 62A, the non-contact portion of the polishing cleaning pad 2993 is remarkably reduced, the use time (number of times) is increased, and the adsorption power (adhesion power) is increased. It is possible to significantly reduce the waste of resources and maintenance costs that occur during disposal due to a decrease.

  The shape of the geometrical movement path 62B as described above is determined by the transfer speed and the rotational speed at which the polishing cleaning pad 2993 is transferred, and there is no particular limitation as long as the movement path 62A is not circular.
