Description

드릴비트의 자동 재연마장치Automatic regrinding device of drill bit
본 발명은 연속공정을 통해 인쇄회로기판의 가공용 드릴비트의 절삭선단을 재연마하고 재연마되어 길이가 짧아진 드릴비트의 장착위치도 자동으로 셋팅해 주는 드릴비트의 자동 재연마장치에 관한 것이다.The present invention relates to an automatic regrinding apparatus of a drill bit for resetting the cutting edge of a drill bit for processing a printed circuit board through a continuous process and automatically setting the mounting position of the drill bit having a shorter length.
인쇄회로기판(Printed Circuit Board)은 각종 열경화성 합성수지로 이루어진 보드의 일면 또는 양면에 동선으로 배선한 후 보드상에 IC 또는 전자부품들을 배치 고정하고 이들 간의 전기적 배선을 구현하여 절연체로 코팅한 것이다. 최근에는 전자부품의 발달로 회로도체를 중첩하여 만드는 다층인쇄회로기판이 개발된 이래, 다층인쇄회로기판의 고밀도화에 관한 연구가 활발하게 진행되고 있다.A printed circuit board is a wired wiring on one or both sides of a board made of various thermosetting synthetic resins, and then an IC or an electronic component is disposed and fixed on the board and coated with an insulator by implementing electrical wiring therebetween. Recently, since the development of electronic components, a multilayer printed circuit board made of overlapping circuit conductors has been developed, and research on increasing the density of multilayer printed circuit boards has been actively conducted.
일반적으로 회로기판에는 주로 수천의 작은 직경의 관통공이 형성되어 있는데, 이 관통공들은 리드(lead) 또는 핀(pin)을 수용함으로써, 회로기판에 여러 가지 부품을 접속하고, 한 층의 전기 회로도 트레이스(trace)를 다른 것에 접속하도록 하며, 연속하는 가공에 대한 기준점을 제공하고, 최종 하우징 내에 완전한 인쇄회로기판을 구비할 수 있도록 하는 데 사용된다.Typically, thousands of small diameter through-holes are formed in a circuit board, which receives leads or pins to connect various components to the circuit board and traces a single layer of electrical circuit. It is used to connect a trace to another, to provide a reference point for continuous machining, and to have a complete printed circuit board in the final housing.
따라서, 상기 관통공들의 직경은 매우 작으며, 이 미세한 관통공들을 천공하기 위한 드릴비트 또한 매우 작은 직경의 절삭선단을 가진다.Thus, the diameter of the through holes is very small, and the drill bit for drilling these fine through holes also has a cutting edge of very small diameter.
상기 드릴비트의 절삭선단은 주로 텅스텐 카바이드(carbide) 등의 매우 단단한 내마모성 재료로 제조되지만, 일정한 수의 구멍을 가공한 후에는 구멍에 대한 기준 직경에 대하여 허용 오차를 유지할 수 있을 만큼 날카롭지 않게 된다.The cutting edge of the drill bit is mainly made of a very hard wear resistant material such as tungsten carbide, but after processing a certain number of holes, it is not sharp enough to maintain tolerances for the reference diameter for the hole.
이와 같이, 드릴비트의 절삭선단이 무뎌지면 드릴비트를 새것으로 교체하는 것보다는 재연마하여 사용하는 것이 비용 측면에서 유리하기 때문에 드릴비트의 재연마장치의 개발이 활발히 이루어지고 있다.As such, when the cutting edge of the drill bit becomes dull, the regrinding device of the drill bit is actively developed because it is advantageous in terms of cost to use the regrind rather than replacing the drill bit with a new one.
최근에는 회전체에 구비된 드릴비트홀더에 드릴비트가 결합된 상태에서 상기 회전체가 단계적 회전하면서 재연마공정이 연속적으로 수행되도록 하는 드릴비트의 자동 재연마장치가 대한민국 등록특허공보 제10-745665호를 통해 알려져 있다Recently, an automatic regrinding apparatus of a drill bit for continuously performing a regrinding process while the rotating body rotates stepwise in a state in which a drill bit is coupled to a drill bit holder provided in the rotating body has been registered in the Republic of Korea Patent Application Publication No. 10-745665 Known through the arc
그러나, 이와 같은 종래의 자동 재연마장치는 드릴비트가 드릴비트홀더의 외측으로 항상 일정한 노출길이를 가지면서 결합될 수 있도록 별도의 자동위치조절부를 구비하여만 하므로 장치의 구성이 복잡할 뿐만 아니라, 드릴비트를 자동위치조절부측으로 공급하고 위치조절이 끝난 후에 상기 드릴비트를 다시 회수해야 하므로 작업시간이 많이 소요되는 문제가 있다.However, such a conventional automatic regrinding device is not only complicated configuration of the device because the drill bit should be provided with a separate automatic position adjusting unit so that the drill bit can be coupled to the outside of the drill bit holder always having a constant exposure length, Since the drill bit is supplied to the automatic position adjusting unit and the position adjustment is completed, the drill bit must be recovered again, which causes a lot of work time.
또한, 상기 종래의 재연마장치는 드릴비트를 재연마하는 과정에서 발생된 스크랩들이 드릴비트의 절삭선단에 달라붙어 있어서 재사용시 불량을 발생시키는 문제가 있다.In addition, the conventional regrinding apparatus has a problem in that scraps generated in the regrinding of the drill bit are stuck to the cutting edge of the drill bit, thereby causing a defect in reuse.
또한, 상기 종래의 재연마장치는 재연마가 완료된 이후 재연마가 정상적으로 이루어졌는지 파악할 수가 없기 때문에 불량으로 재연마된 드릴비트가 재사용되는 경우가 종종 발생되는 문제가 있다.In addition, the conventional regrinding apparatus has a problem in that it is often a case that the reusable drill bit is reused because it cannot determine whether regrinding is normally performed after the regrinding is completed.
한편, 각각의 드릴비트는 사용과정에서 마모되는 정도가 각기 다르기 때문에 절삭선단의 길이가 모두 일정하지 않다. 따라서 재연마 이후에 가공드릴에 장착되어 재사용될 때 가공드릴의 선단과 드릴비트의 절삭선단과의 거리차이로 인해 가공되는 인쇄회로기판상의 관통공의 깊이가 달라지는 문제가 발생되지 않도록, 도 1에 도시된 바와 같이, 드릴비트(10)의 몸체부(12)에는 위치결정링(13)이 끼워져 있다. 이 위치결정링(13)은 드릴비트(10)의 절삭선단(11)으로부터 일정한 거리에 위치되도록 셋팅되어 드릴비트(10)가 드릴공구 홀더에 항상 정확한 위치에서 고정될 수 있도록 하는 기준이 된다.On the other hand, the length of the cutting edge is not constant because each of the drill bit is different in the degree of wear in use. Therefore, when the re-grinding is mounted on the machining drill and reused, the difference in the depth of the through hole on the printed circuit board does not occur due to the distance difference between the tip of the machining drill and the cutting edge of the drill bit. As shown, the positioning ring 13 is fitted to the body portion 12 of the drill bit 10. The positioning ring 13 is set so as to be positioned at a predetermined distance from the cutting edge 11 of the drill bit 10, so that the drill bit 10 is always fixed to the drill tool holder in the correct position.
이러한 위치결정링(13)의 위치는 재연마 이후에 재조정해 주어야만 한다. 왜냐하면 재연마 과정에서 드릴비트(10)의 절삭선단(11)의 길이가 짧아지기 때문이다. 만일 위치결정링(13)의 위치를 재조정해 주지 않으면 가공드릴에 장착되어 재사용될 때 가공드릴의 선단과 드릴비트(10)의 절삭선단(11)과의 거리차이로 인해 가공되는 인쇄회로기판상의 관통공의 깊이가 달라지게 된다.The position of this positioning ring 13 must be readjusted after repolishing. This is because the length of the cutting edge 11 of the drill bit 10 is shortened in the repolishing process. If the position of the positioning ring 13 is not readjusted on the printed circuit board which is processed due to the distance difference between the tip of the machining drill and the cutting tip 11 of the drill bit 10 when it is mounted and reused in the machining drill, The depth of the through hole will be different.
그러나, 종래에는 작업자가 버어니어캘리퍼스와 같은 계측기구를 이용하여 각 드릴비트(10)의 절삭선단(11)과 위치결정링(13) 사이의 거리를 일일이 계측한 후 수작업으로 위치결정링(13)의 위치를 보정해 주었으므로 작업성이 매우 불량하고 생산성이 크게 떨어질 뿐만 아니라, 작업자의 숙련도에 따라 그 정밀성과 작업속도에 있어서 큰 차이가 있었다.However, in the related art, the operator manually measures the distance between the cutting tip 11 and the positioning ring 13 of each drill bit 10 using a measuring device such as a vernier caliper, and then manually positions the ring 13 Since the position of) is corrected, the workability is very poor and the productivity is greatly reduced, and there is a big difference in the precision and work speed according to the skill of the operator.
본 발명의 목적은 별도의 위치조절장치 없이도 드릴비트의 높이가 항상 일정하도록 드릴비트홀더에 장착된 드릴비트의 절삭선단의 높이를 조절할 수 있는 드릴비트의 자동 재연마장치를 제공하기 위한 것이다.An object of the present invention is to provide an automatic regrinding apparatus of a drill bit that can adjust the height of the cutting edge of the drill bit mounted on the drill bit holder so that the height of the drill bit is always constant even without a separate position adjusting device.
또한, 본 발명의 목적은 재연마시 발생된 스크랩을 드릴비트로부터 제거할 수 있게 되는 드릴비트의 자동 재연마장치를 제공하기 위한 것이다.It is also an object of the present invention to provide an automatic regrinding apparatus of a drill bit, which makes it possible to remove scrap generated during regrinding from the drill bit.
또한, 본 발명의 목적은 재연마가 정상적으로 이루어졌는지 파악할 수 있게 되는 드릴비트의 자동 재연마장치를 제공하기 위한 것이다.It is also an object of the present invention to provide an automatic regrinding apparatus of a drill bit that can determine whether regrinding is normally performed.
또한, 본 발명의 목적은 드릴비트가 가공드릴에 장착되어 재사용되는 경우, 드릴비트의 종류에 상관없이 가공드릴의 선단과 드릴비트의 절삭선단 사이의 거리를 항상 일정하게 셋팅해 주는 드릴비트의 자동 재연마장치를 제공하기 위한 것이다.In addition, the object of the present invention is to automatically set the drill bit to always set the distance between the cutting end of the drill bit and the cutting end of the drill bit, regardless of the type of the drill bit when the drill bit is mounted on the machining drill and reused It is to provide a regrinding device.
또한, 본 발명의 목적은 재연마 후 드릴비트에 끼워진 위치결정링이 드릴비트의 절삭선단으로부터 항상 일정한 거리에 위치하도록 자동으로 신속하게 셋팅해 주는 드릴비트의 자동 재연마장치를 제공하기 위한 것이다.It is also an object of the present invention to provide an automatic regrinding apparatus for a drill bit that automatically sets the positioning ring fitted to the drill bit after regrinding so that it is always located at a constant distance from the cutting edge of the drill bit.

The determination ring 13 is moved to the setting point, and the positioning ring push bar 642 is cut from the fourth optical inspector 630 at one side of the through hole 642b and the cutting edge of the drill bit 10. When the position information of the drill bit 10 is transmitted that 11 matches, the descending operation is immediately stopped.
또한, 도 28 및 도 29에 도시된 바와 같이, 턴테이블(610)이 3단계 회전한 제3위치에는 드릴비트홀더(611)로부터 위치결정링(13)의 셋팅이 완료된 드릴비트(10)를 탈착시켜 반전시킨 다음 드릴비트홀더(611)에 재장착시키는 반전로봇(650)이 설치될 수 있다. 반전로봇(650)을 통해 반전된 드릴비트(10)는 절삭선단(11)이 드릴비트홀더(611)의 하부로 노출된 상태가 된다.In addition, as shown in FIGS. 28 and 29, the drill bit 10 having completed setting of the positioning ring 13 is removed from the drill bit holder 611 at the third position where the turntable 610 is rotated three steps. Inverted robot 650 to be reversed and then remounted in the drill bit holder 611 may be installed. The drill bit 10 inverted through the inversion robot 650 is in a state in which the cutting edge 11 is exposed to the lower portion of the drill bit holder 611.
드릴비트(10)를 반전시키는 이유는 절삭선단(11)이 하부로 향하게 함으로써 드릴비트(10)를 드릴비트홀더(611)로부터 탈거시킬 때 절삭선단(11)의 손상을 막도록 하기 위함이다.The reason for reversing the drill bit 10 is to prevent the damage of the cutting tip 11 when the drill bit 10 is removed from the drill bit holder 611 by directing the cutting tip 11 downward.
아울러, 도 30에 도시된 바와 같이, 턴테이블(610)이 4단계 회전한 제4위치에는 반전된 상태로 드릴비트홀더(611)에 재장착된 드릴비트(10)를 탈거시켜 드릴비트(10) 보관함으로 이송시키는 드릴비트언로딩유닛(700)이 더 구비될 수 있다.In addition, as illustrated in FIG. 30, the drill bit 10 may be removed by removing the drill bit 10 mounted on the drill bit holder 611 in an inverted state at the fourth position where the turntable 610 is rotated four steps. Drill bit unloading unit 700 for transferring to the storage may be further provided.

도 2 및 도 31에 도시된 바와 같이, 드릴비트언로딩로봇(700)은 회전체(100)의 제4회전위치에 설치되어 연마 또는 세정 또는 위치결정링(13)의 셋팅이 완료된 드릴비트(10)를 드릴비트 보관함(B)으로 운반한다.As shown in Figure 2 and 31, the drill bit unloading robot 700 is installed in the fourth rotation position of the rotary body 100, the grinding or cleaning or positioning of the positioning ring 13 is completed drill bit ( Transport 10) to the drill bit storage box (B).
즉, 상기 드릴비트언로딩로봇(700)은 연마가 완료되거나 세정이 완료된 드릴비트(10)를 드릴홀더유닛으로부터 탈착시켜 드릴비트 보관함(B)으로 이송시키도록 동작된다.That is, the drill bit unloading robot 700 is operable to remove the drill bit 10 is polished or cleaned is completed from the drill holder unit to transfer to the drill bit storage (B).
만일, 위치결정링셋팅기(600)가 설치된 경우, 상기 드릴비트언로딩로봇(700)은 연마가 완료된 드릴비트(10)를 드릴비트홀더(130)로부터 탈착시켜 위치결정링셋팅기(600)로 공급해주고 위치결정링(13)의 셋팅이 완료된 드릴비트(10)를 위치결정링셋팅기(600)로부터 탈착시켜 드릴비트 보관함(B)으로 이송시키도록 동작된다.If the positioning ring setter 600 is installed, the drill bit unloading robot 700 detaches the drill bit 10 from the drill bit holder 130 and supplies it to the positioning ring setter 600. And the drill bit 10 having completed the setting of the positioning ring 13 is removed from the positioning ring setter 600 and transferred to the drill bit storage box B.
세정기(500)와 위치결정링셋팅기(600)가 모두 설치된 경우, 드릴비트언로딩로봇(700)은 세정이 완료되고 제3광학검사기(550)에 의해 양품으로 판정된 드릴비트(10)를 드릴비트홀더(130)로부터 탈착시켜 위치결정링셋팅기(600)로 공급해주고 위치결정링(13)의 셋팅이 완료된 드릴비트(10)를 위치결정링셋팅기(600)로부터 탈착시켜 드릴비트 보관함(B)으로 이송시키도록 동작된다.When both the cleaner 500 and the positioning ring setter 600 are installed, the drill bit unloading robot 700 drills the drill bit 10 determined to be good by the third optical inspector 550 after cleaning is completed. Detach from the bit holder 130 and supply it to the positioning ring setter 600, and remove the drill bit 10, the setting of the positioning ring 13 is completed from the positioning ring setter 600, the drill bit storage box (B) It is operated to transfer.
이와 같이 드릴비트언로딩로봇(700)은 위치결정링셋팅기(600)가 설치된 경우 드릴비트(10)를 드릴비트홀더(130)와 위치결정링셋팅기(600)로부터 탈착시켜야 하므로 효율적인 동작수행을 위해 제1언로딩부(710)와 제2언로딩부(720)로 구성되는 것이 바람직하다. 즉, 제1언로딩부(710)는 드릴비트(10)를 드릴비트홀더(130)에서 탈착시켜 위치결정링셋팅기(600)로 공급해 주는 동작을 수행하도록 하고 제2언로딩부(720)는 드릴비트(10)를 위치결정링셋팅기(600)로부터 탈착시켜 드릴비트 보관함(B)으로 이송시키는 동작을 수행하도록 한다.As such, when the positioning bit setter 600 is installed, the drill bit unloading robot 700 needs to remove the drill bit 10 from the drill bit holder 130 and the positioning ring setter 600 so as to perform an efficient operation. Preferably, the first unloading unit 710 and the second unloading unit 720 are configured. That is, the first unloading unit 710 detaches the drill bit 10 from the drill bit holder 130 to supply the positioning ring setter 600, and the second unloading unit 720 performs the operation. The drill bit 10 is detached from the positioning ring setter 600 to be transferred to the drill bit storage box B.
즉, 상기 제1언로딩부(710)는 바닥으로부터 일정높이에서 z축방향으로 이동하도록 설치된 슬라이더(711)와, 상기 슬라이더(711)상에 리프팅 가능하게 설치된 y축이송유닛(712)과, 상기 y축이송유닛(712)의 하단에 설치되어 드릴비트(10)의 양측을 잡아서 고정하는 집게고정부(713)로 구성된다. 상기 집게고정부(713)는 x축방향에 위치된 회전체(100)의 드릴비트홀더(130)에 드릴비트(10)를 탈착시킬 수 있도록 z축을 중심으로 회전가능하게 설치된다. 상기 제2언로딩부(720)는 집게고정부(713)가 회전가능하게 설치되지 않은 것을 제외하고는 제1언로딩부(710)와 대동소이하므로 상세한 설명은 생략하기로 한다.That is, the first unloading unit 710 includes a slider 711 installed to move in a z-axis direction at a predetermined height from the bottom, a y-axis transfer unit 712 provided to be liftable on the slider 711, and It is installed at the lower end of the y-axis transfer unit 712 is composed of a clamping fixing part 713 to hold and fix both sides of the drill bit (10). The tongs fixing part 713 is rotatably installed around the z-axis so that the drill bit 10 can be detached from the drill bit holder 130 of the rotating body 100 located in the x-axis direction. Since the second unloading unit 720 is substantially the same as the first unloading unit 710 except that the tong fixing part 713 is not rotatably installed, a detailed description thereof will be omitted.
이와 같이 구성된 본 발명은 다음과 같은 과정을 거쳐 드릴비트를 재연마하게 된다.In the present invention configured as described above, the drill bit is regrind through the following process.
먼저, 드릴비트 공급함(A)이 제1회전위치에 위치된 드릴비트로딩로봇(300)측으로 이송되면, 드릴비트로딩로봇(300)이 드릴비트 공급함(A)으로 접근하여 드릴비트 공급함(A)에 수용된 연마대상이 되는 드릴비트(10)를 잡은 다음 전방의 회전체(100)에 구비된 드릴비트홀더(130)에 로딩시킨다.First, when the drill bit supply box (A) is transferred to the drill bit loading robot 300 side located in the first rotational position, the drill bit loading robot 300 approaches the drill bit supply box (A) to supply the drill bit (A) The drill bit 10 to be subjected to the polishing object received in the grab and then loaded in the drill bit holder 130 provided in the front rotating body (100).
이때, 드릴비트홀더(130)의 전방에 설치된 척킹해제블럭(150)은 드릴비트홀더(130)의 잠금슬리브(141)의 높이로 상승한 다음 잠금슬리브(141)측으로 이동하여 콜렛척(140)의 척킹상태를 해제하도록 한다.At this time, the chucking release block 150 installed in front of the drill bit holder 130 ascends to the height of the locking sleeve 141 of the drill bit holder 130 and then moves to the locking sleeve 141 side of the collet chuck 140. Release the chucking state.
드릴비트홀더(130)에 드릴비트(10)가 로딩되면 제1광학검사기(200)가 드릴비트홀더(130)의 선단으로부터 드릴비트(10)의 절삭선단까지의 거리를 측정하고 그 기준위치에 드릴비트(10)의 절삭선단이 위치되도록 위치보정정보를 드릴비트로딩로봇(300)으로 전송한다. 위치보정정보를 전달받은 드릴비트로딩로봇(300)은 슬라이더(310)의 동작을 제어하여 드릴비트(10)의 절삭선단의 위치를 보정한다.When the drill bit 10 is loaded in the drill bit holder 130, the first optical inspector 200 measures the distance from the tip of the drill bit holder 130 to the cutting end of the drill bit 10 and then at the reference position. The position correction information is transmitted to the drill bit loading robot 300 so that the cutting edge of the drill bit 10 is positioned. The drill bit loading robot 300 receiving the position correction information corrects the position of the cutting edge of the drill bit 10 by controlling the operation of the slider 310.
이와 같이, 드릴비트로딩로봇(300)이 드릴비트홀더(130)에 드릴비트(10)를 로딩시킨 상태에서 제1광학검사기(200)로부터 위치보정정보를 전달받아 곧바로 드릴비트(10)를 정렬시키기 때문에 드릴비트(10)의 장착과정은 매우 신속하게 이루어진다.As such, the drill bit loading robot 300 receives the position correction information from the first optical inspector 200 while the drill bit 10 is loaded in the drill bit holder 130 to align the drill bit 10 immediately. Since the mounting process of the drill bit 10 is made very quickly.
한편, 드릴비트(10)의 절삭선단이 기준위치에 위치되면, 척킹해제블럭(150)이 하강하게 되는데 그 결과 잠금슬리브(141)가 원래 위치로 복귀하면서 콜렛척(140)이 드릴비트(10)를 척킹하게 된다. 드릴비트(10)의 척킹이 완료되면 드릴비트로딩로봇(300)은 원래 위치로 복귀하여 다음 드릴비트(10)의 로딩을 준비한다.On the other hand, when the cutting edge of the drill bit 10 is located in the reference position, the chucking release block 150 is lowered as a result, the lock sleeve 141 is returned to the original position while the collet chuck 140 is drill bit (10) Chucking). When the chucking of the drill bit 10 is completed, the drill bit loading robot 300 returns to its original position to prepare for loading of the next drill bit 10.
드릴비트로딩로봇(300)이 원래 위치로 복귀함과 동시에 회전체(100)는 턴테이블(111)을 제2회전위치로 회전시킨다. 이에 따라서, 드릴비트홀더(130)에 장착된 드릴비트(10)도 턴테이블(111)을 따라 제2회전위치로 이동된다. 제2회전위치에서는 전방에 설치된 재연마기(400)에 의해 드릴비트(10) 재연마가 이루어진다.Simultaneously with the drill bit loading robot 300 returning to its original position, the rotor 100 rotates the turntable 111 to a second rotational position. Accordingly, the drill bit 10 mounted on the drill bit holder 130 is also moved to the second rotational position along the turntable 111. In the second rotational position, the drill bit 10 is regrind by the regrinding machine 400 installed at the front.
재연마가 이루어지기에 앞서, 재연마시 재연마기(400)에서 드릴비트(10)로 전달되는 진동에 의해 재연마가 정밀하게 이루어지지 못하게 되는 것을 방지하도록 제2회전위치의 회전체(100) 전방에 설치된 엘리베이터(150)에 의해 지지블럭(151)이 상승하면서 드릴비트(10)의 절삭선단을 지지해준다. 이때의 콜렛척(131)은 콜렛척지지유닛(133)을 통해 수평상태를 안정적으로 유지되고 있는 상태이다.Prior to the re-polishing, the re-polishing is installed in front of the rotating body 100 of the second rotation position to prevent the re-polishing is not made precisely by the vibration transmitted from the re-polishing machine 400 to the drill bit 10 during the re-polishing The support block 151 is lifted by the elevator 150 to support the cutting edge of the drill bit 10. At this time, the collet chuck 131 is in a state in which the horizontal state is stably maintained through the collet chuck support unit 133.
지지블럭(151)의 상단에 안착홈(152)이 형성된 경우, 상기 드릴비트(10)의 절삭선단은 안착홈(152)에 안착되면서 좌우측으로 유동되지 않도록 구속된 상태가 된다.When the mounting groove 152 is formed at the upper end of the support block 151, the cutting tip of the drill bit 10 is restrained so as not to flow to the left and right while being seated in the mounting groove 152.
드릴비트(10)의 절삭선단이 지지블럭(151)에 의해 안정적으로 지지되면, 제1광학검사기(200)가 드릴비트(10)의 절삭선단의 높이를 측정한다. 드릴비트(10)는 절삭선단의 외경이 달라질 때마다 절삭선단의 높이가 달라지므로 제1광학검사기(200)는 드릴비트(10)의 절삭선단을 촬영하고 그 높이정보를 제어부로 전송한다.When the cutting edge of the drill bit 10 is stably supported by the support block 151, the first optical inspector 200 measures the height of the cutting edge of the drill bit 10. Since the height of the cutting tip is changed whenever the outer diameter of the cutting bit 10 is different, the first optical inspector 200 photographs the cutting edge of the drill bit 10 and transmits the height information to the controller.
높이정보를 전송받은 제어부는 절삭선단의 높이가 기준높이보다 얼마나 차이가 나는지 판단하여 보정거리를 계산한 다음 엘리베이터(150)의 동작을 제어하여 드릴비트(10)가 유니버셜조인트(132)를 기준으로 상하로 회전하면서 드릴비트(10)의 절삭선단 높이가 조절되도록 한다.The controller receiving the height information determines how much the height of the cutting edge differs from the reference height, calculates a correction distance, and then controls the operation of the elevator 150 to control the drill bit 10 based on the universal joint 132. The cutting tip height of the drill bit 10 is adjusted while rotating up and down.
드릴비트(10)의 절삭선단 높이가 조절되는 과정을 보다 구체적으로 살펴보면 다음과 같다.Looking at the process of adjusting the cutting edge height of the drill bit 10 in more detail as follows.
제어부는 먼저 수직실린더(134a)의 로드를 하강시킨다. 수직실린더(134a)의 로드가 하강하면 가이드편(134c)에 승강블럭(133b)의 걸림돌기(134b)가 수용된 상태이므로 수직실린더(134a)의 로드를 따라 승강블럭(133b)이 하강하게 되고 그 결과 콜렛척(131)은 유니버셜조인트를 중심으로 상하회동이 자유로운 상태가 된다.The controller first lowers the rod of the vertical cylinder 134a. When the rod of the vertical cylinder 134a is lowered, the locking projection 134b of the lifting block 133b is accommodated in the guide piece 134c. Thus, the lifting block 133b is lowered along the rod of the vertical cylinder 134a. The collet chuck 131 is free to rotate up and down about the universal joint.
그리고, 제어부는 드릴비트(10)의 절삭선단 높이가 기준높이보다 높을 경우, 엘리베이터(150)를 하강구동시켜 지지블럭(151)을 하강시킨다. 지지블럭(151)이 하강함에 따라 콜렛척(131)이 유니버셜조인트(132)를 기준으로 자중에 의해 하향회전하게 되고, 그 결과 도 9에 도시된 바와 같이, 드릴비트(10)의 절삭선단은 지지블럭(151)의 안착홈(152)에 안착된 상태로 지지블럭(151)을 따라 하강하면서 되면서 높이가 낮아지게 된다.When the cutting tip height of the drill bit 10 is higher than the reference height, the controller lowers the elevator 150 to lower the support block 151. As the support block 151 is lowered, the collet chuck 131 is rotated downward by its own weight based on the universal joint 132. As a result, as shown in FIG. 9, the cutting tip of the drill bit 10 is The height decreases while descending along the support block 151 while being seated in the seating groove 152 of the support block 151.
만일, 드릴비트(10)의 절삭선단 높이가 기준높이보다 낮을 경우, 제어부는 엘리베이터(150)를 하강구동시켜 지지블럭(151)을 상승시킨다. 지지블럭(151)이 상승함에 따라 콜렛척(131)이 유니버셜조인트(132)를 기준으로 상향회동하게 되며, 그 결과 도 10에 도시된 바와 같이, 드릴비트(10)의 절삭선단의 높이가 상승된다.If the cutting tip height of the drill bit 10 is lower than the reference height, the control unit drives the elevator 150 down to raise the support block 151. As the support block 151 rises, the collet chuck 131 pivots up relative to the universal joint 132. As a result, as shown in FIG. 10, the height of the cutting edge of the drill bit 10 increases. do.
한편, 엘리베이터(150)에 승강가이드(153)가 더 설치된 경우,드릴비트(10)의 절삭선단의 높이가 기준위치에 도달한 이후, 승강가이드(153)가 하강하면서 드릴비트(10)의 상부를 커버해 준다. 이때, 가압돌기(153a)는 드릴비트(10)의 절삭선단의 상부를 가압해 준다. 이에 따라서, 드릴비트(10)는 드릴비트 안착홈(152)내에서 안정적으로 지지된 상태가 되므로 재연마시 유동되지 않고 정밀하게 가공될 수 있게 된다.On the other hand, when the lifting guide 153 is further installed in the elevator 150, after the height of the cutting edge of the drill bit 10 reaches the reference position, the lifting guide 153 is lowered and the upper portion of the drill bit 10 Cover it. At this time, the pressing protrusion 153a presses the upper portion of the cutting tip of the drill bit 10. Accordingly, since the drill bit 10 is stably supported in the drill bit seating groove 152, the drill bit 10 may be precisely processed without flowing during re-polishing.
그리고 제2광학검사기(460)가 드릴비트(10)의 절삭선단의 각도를 검사한다. 제2광학검사기(460)는 드릴비트(10)의 절삭선단을 정면에서 촬영하고 절삭선단이 이루는 각도가 기준각도에 일치하는지 검사하고 그 각도보정정보를 드릴비트홀더 회전용 모터(M)로 전송한다. 제2광학검사기(460)로부터 각도보정정보를 전송받은 드릴비트홀더 회전용 모터(M)는 드릴비트홀더(130)를 회전시켜 드릴비트(10)의 절삭선단의 각도를 보정해준다. 드릴비트(10)의 각도가 보정되면, 재연마기(400)를 통해 드릴비트(10)의 절삭선단의 재연마가 정밀하게 진행된다The second optical inspector 460 inspects the angle of the cutting edge of the drill bit 10. The second optical inspector 460 photographs the cutting tip of the drill bit 10 from the front, checks whether the angle formed by the cutting tip corresponds to the reference angle, and transmits the angle correction information to the drill bit holder rotating motor (M). do. The drill bit holder rotation motor M, which receives the angle correction information from the second optical inspector 460, rotates the drill bit holder 130 to correct the angle of the cutting tip of the drill bit 10. When the angle of the drill bit 10 is corrected, the regrinding of the cutting tip of the drill bit 10 proceeds precisely through the regrinding machine 400.
드릴비트(10)의 재연마가 완료되면, 제어부는 수직실린더(134a)의 로드에 제공된 하강력이 제거되거나 수직실린더(134a)의 로드가 원래 위치로 상승되도록 제어한다. 이때의 탄성부재(135b)는 승강블럭(133b)을 따라 하강하면서 고정나사(135a)에 눌려 압축된 상태로서, 수직실린더(134a)의 로드에 제공된 하강력이 제거되거나 수직실린더(134a)의 로드가 원래 위치로 상승되면, 승강블럭(133b)이 상기 탄성부재(135b)로부터 상승력을 제공받아 자연스럽게 상승하게 된다. 그 결과 드릴비트(10)가 상향회동되면서 원래 위치로 복귀되어 수평상태로 안정되게 지지된다.When the regrinding of the drill bit 10 is completed, the control unit controls such that the lowering force provided to the rod of the vertical cylinder 134a is removed or the rod of the vertical cylinder 134a is raised to its original position. At this time, the elastic member 135b is pressed down by the fixing screw 135a while descending along the elevating block 133b, and the lowering force provided to the rod of the vertical cylinder 134a is removed or the rod of the vertical cylinder 134a is removed. When is raised to the original position, the lifting block 133b is naturally raised by receiving the lifting force from the elastic member (135b). As a result, the drill bit 10 is rotated upward and returned to its original position, thereby being stably supported in a horizontal state.
드릴비트(10)가 수평상태로 안정적으로 지지되면, 회전체(100)가 다음 공정의 수행을 위하여 회전한다. 회전체(100)가 회전함에 따라 승강블럭(133b)의 걸림돌기(134b)는 가이드편(134c)들 사이의 이격공간을 따라 이동하면서 가이드편(134c)을 빠져나오게 되고, 콜렛척(131) 및 드릴비트(10)는 회전판을 따라 다음 공정으로 무리없이 이동하게 된다.When the drill bit 10 is stably supported in a horizontal state, the rotating body 100 rotates to perform the next process. As the rotating body 100 rotates, the engaging protrusion 134b of the lifting block 133b moves out of the guide piece 134c while moving along the spaced space between the guide pieces 134c, and the collet chuck 131 And the drill bit 10 is moved to the next step along the rotating plate without difficulty.
회전체(100)가 턴테이블(111)을 제3회전위치로 회전시키면, 재연마된 드릴비트(10)도 턴테이블(111)을 따라 제3회전위치로 이동된다.When the rotating body 100 rotates the turntable 111 to the third rotational position, the regrinded drill bit 10 is also moved to the third rotational position along the turntable 111.
제3회전위치로 이동된 드릴비트(10)는 세정기(500)에 의해 다음과 같은 과정을 거쳐 세정된다.The drill bit 10 moved to the third rotational position is cleaned by the cleaner 500 through the following process.
먼저, 도 16에 도시된 바와 같이, 드릴비트(10)의 절삭선단이 점착성물질(510)에 삽입되면, 드릴비트(10)의 절삭선단에 달라붙은 각종 이물질(10)들이 점착성물질(510)에 달라붙으면서 깨끗하게 제거된다.First, as shown in FIG. 16, when the cutting tip of the drill bit 10 is inserted into the adhesive material 510, various foreign materials 10 stuck to the cutting tip of the drill bit 10 are adhered to the adhesive material 510. It will be removed cleanly by clinging to.
이어서 세정통 이송유닛(530)이 세정통(520)을 후방으로 이동시키도록 동작된다. 도 15에 도시된 바와 같이, 세정통(520)이 후방으로 이동하여 드릴비트(10)의 절삭선단이 세정통(520)으로부터 빠져나오게 되면, 구동모터(540)가 일시적으로 동작하면서 도 19 및 20에 도시된 바와 같이 세정통(520)을 일정량 회동시킨다. 구동모터(540)의 회전축(21)은 드릴비트(10)의 절삭선단과 동일축선상에 위치되지 않도록 구성되어 있기 때문에 드릴비트(10)의 절삭선단이 점착성물질(510)의 동일한 지점으로 중복삽입되지 않는다. 따라서, 세정작업을 다수회에 걸쳐 반복실시하여도 세정능력이 떨어지지 않고 항상 최적의 세정성능을 발휘할 수 있게 된다.Subsequently, the washing tub transfer unit 530 is operated to move the washing tub 520 backward. As shown in FIG. 15, when the cleaning cylinder 520 is moved rearward so that the cutting edge of the drill bit 10 comes out of the cleaning cylinder 520, the driving motor 540 is temporarily operated while the driving motor 540 is temporarily operated. As shown in FIG. 20, the washing tub 520 is rotated by a predetermined amount. Since the rotating shaft 21 of the drive motor 540 is configured not to be positioned on the same axis as the cutting end of the drill bit 10, the cutting end of the drill bit 10 overlaps the same point of the adhesive material 510. It is not inserted. Therefore, even if the cleaning operation is repeated a plurality of times, the cleaning performance is not degraded and the optimum cleaning performance can be exhibited at all times.
미설명 부호 P는 드릴비트(10)의 절삭선단이 삽입된 지점이다.Reference numeral P is a point at which the cutting edge of the drill bit 10 is inserted.
세정이 완료된 드릴비트(10)는 후속공정으로 이송된다.The drill bit 10 having been cleaned is transferred to a subsequent process.
한편, 제3광학검사기(550)가 더 구비된 경우, 드릴비트(10)는 세정이 완료된 이후에 재연마가 정상적으로 이루어졌는지를 다음과 같은 연속공정을 통해 파악할 수가 있게 된다.On the other hand, when the third optical inspector 550 is further provided, the drill bit 10 can determine whether the re-polishing is normally performed after the cleaning is completed through the following continuous process.
즉, 도 17에 도시된 상태에서 드릴비트(10)의 세정이 완료되면, 슬라이더(560)가 슬라이딩블럭(563)을 일측방향으로 이동하도록 동작된다.That is, when cleaning of the drill bit 10 is completed in the state shown in FIG. 17, the slider 560 is operated to move the sliding block 563 in one direction.
이와 같이, 슬라이딩블럭(563)이 일측으로 이동하면, 도 18에 도시된 바와 같이, 슬라이딩블럭(563)의 타측에 설치된 제3광학검사기(550)의 조명(552)이 세정이 완료된 드릴비트(10)의 전방에 위치하게 된다. 이 상태에서 조명(552)이 점등되며, 조명(552)의 전방에 설치된 카메라(551)가 드릴비트(10)의 절삭선단을 절삭선단의 중심과 동일한 위치에서 정면으로 촬영한다.As such, when the sliding block 563 moves to one side, as shown in FIG. 18, the illumination bit 552 of the third optical inspector 550 installed on the other side of the sliding block 563 may be cleaned. 10) in front of. In this state, the illumination 552 is turned on, and the camera 551 installed in front of the illumination 552 photographs the cutting edge of the drill bit 10 at the same position as the center of the cutting edge.
상기 카메라(551)가 촬영한 영상정보는 제어부로 전송되며, 제어부는 미리 프로그램된 정상 절삭선단의 영상과 전송받은 영상정보를 비교분석하여 양품과 불량품을 판정한다.The image information photographed by the camera 551 is transmitted to the control unit, and the control unit compares the image of the pre-programmed normal cutting edge with the received image information to determine good or bad.
드릴비트의 세정 및 양불검사가 완료되면, 회전체(100)는 턴테이블(111)을 제4회전위치로 회전시킨다. 제4회전위치에서는 드릴비트언로딩로봇(700)에 의해 재연마가 완료된 드릴비트(10)가 드릴비트홀더(130)로부터 탈착시킨 후 드릴비트 보관함(B)으로 운반된다. 이때, 드릴비트언로딩로봇(700)은 양품과 불량품을 구분하여 드릴비트 보관함(B)으로 운반한다.When the cleaning of the drill bit and the inspection of the failure are completed, the rotating body 100 rotates the turntable 111 to the fourth rotational position. In the fourth rotational position, the drill bit 10 having been regrinded by the drill bit unloading robot 700 is removed from the drill bit holder 130 and then transported to the drill bit storage box B. At this time, the drill bit unloading robot 700 is transported to the drill bit storage box (B) to distinguish between good and bad.
만일, 드릴비트(10)가 위치결정링(13)을 구비한 경우에는 제4회전위치에 위치결정링셋팅기(600)가 설치된다. 이 경우, 드릴비트언로딩로봇(700)은 양품으로 판정된 드릴비트(10)만을 위치결정링셋팅기(600)로 이동시키고 불량품으로 판정된 드릴비트(10)는 곧바로 불량 드릴비트 보관함(B)으로 운반한다.If the drill bit 10 includes the positioning ring 13, the positioning ring setter 600 is installed at the fourth rotational position. In this case, the drill bit unloading robot 700 moves only the drill bit 10 that is determined to be good to the positioning ring setter 600, and the drill bit 10 that is determined to be defective is immediately a bad drill bit storage box (B). To transport.
양품으로 판정된 드릴비트(10)는 상기 드릴비트언로딩로봇(700)의 제1언로딩부(710)에 의해 드릴비트홀더(130)로부터 탈착된 후 위치결정링셋팅기(600)의 작업테이블(610)에 장착된다.The drill bit 10, which is determined to be good, is removed from the drill bit holder 130 by the first unloading part 710 of the drill bit unloading robot 700, and then the work table of the positioning ring setter 600. 610.
이때 드릴비트(10)는 절삭선단(11)이 상부를 향하도록 드릴비트 끼움공(611a)에 끼워져 수직으로 장착된다. 이와 같이 드릴비트(10)가 장착되면 턴테이블(610)이 1단계 회전한다.At this time, the drill bit 10 is fitted in the drill bit fitting hole (611a) so that the cutting edge 11 is directed upward, it is mounted vertically. When the drill bit 10 is mounted in this way, the turntable 610 rotates by one step.
턴테이블(610)이 1단계 회전하면, 드릴비트홀더(611)가 제1위치로 이동하게 되는데, 이때의 드릴비트홀더(611)는 턴테이블(610)의 상부로부터 탄성적으로 이격되게 설치되었기 때문에 제1위치에 설치된 수직받침대(623)와 간섭되지 않고 원활하게 회전된다.When the turntable 610 is rotated by one step, the drill bit holder 611 is moved to the first position. In this case, the drill bit holder 611 is elastically spaced apart from the upper part of the turntable 610. It rotates smoothly without interfering with the vertical support 623 installed in one position.
도 17에 도시된 바와 같이, 드릴비트홀더(611)가 제1위치로 이동하게 되면, 드릴비트홀더(611)의 상부로부터 드릴비트푸쉬바(620)가 수직하강하게 된다.As shown in FIG. 17, when the drill bit holder 611 moves to the first position, the drill bit push bar 620 is vertically lowered from the upper portion of the drill bit holder 611.
그 결과 도 18에 도시된 바와 같이, 드릴비트(10)의 절삭선단(11)이 드릴비트푸쉬바(620)의 저면에 형성된 삽입홈(621a)으로 삽입되고 드릴비트(10)의 몸체부(12)가 드릴비트푸쉬바(620)의 누름단(621b)과 접촉하면서 아래로 밀려 이동된다. 이와 동시에, 드릴비트(10)의 몸체부(12)에 끼워져 있는 위치결정링(13)은 드릴비트(10)의 몸체부(12)를 따라 절삭선단(11)측으로 이동하게 된다. 이때, 상기 드릴비트푸쉬바(620)는 드릴비트(10)마다 각기 다른 지점에 끼워져 있는 위치결정링(13)을 정상적인 셋팅위치보다 절삭선단(11)측으로 과도하게 근접하도록 이동시킨다. 이는, 이후에 이루어질 위치결정링(13)의 셋팅공정이 위치결정링(13)을 모두 동일한 방향으로 이동시키면서 수행될 수 있도록 하기 위함이다.As a result, as shown in FIG. 18, the cutting end 11 of the drill bit 10 is inserted into the insertion groove 621 a formed in the bottom of the drill bit push bar 620 and the body portion of the drill bit 10 ( 12 is pushed down while in contact with the pressing end (621b) of the drill bit push bar (620). At the same time, the positioning ring 13 fitted to the body portion 12 of the drill bit 10 is moved along the body portion 12 of the drill bit 10 toward the cutting edge 11 side. At this time, the drill bit push bar 620 moves the positioning ring 13, which is fitted at different points for each drill bit 10, to be closer to the cutting edge 11 side than the normal setting position. This is for the subsequent setting process of the positioning ring 13 to be performed while moving the positioning ring 13 all in the same direction.
한편, 드릴비트푸쉬바(620)에 의해 드릴비트(10)가 아래로 이동하면 위치결정링(13)이 드릴비트홀더(611)의 상면과 접촉되면서 드릴비트홀더(611)를 아래로 누르게 된다. 이 과정에서 드릴비트홀더(611)를 탄성지지하고 있던 탄성부재(611d)가 압축되면서 드릴비트(10)는 수평상태로 회동되며, 제1위치에 설치된 수직받침대(623)에 의해 하부가 지지되어 수평상태를 안정적으로 유지할 수 있게 된다. 따라서, 드릴비트(10)는 안정적으로 수직하강하게 된다.On the other hand, when the drill bit 10 is moved downward by the drill bit push bar 620, the positioning ring 13 is in contact with the upper surface of the drill bit holder 611 to press the drill bit holder 611 down. . In this process, while the elastic member 611d, which was elastically supporting the drill bit holder 611, is compressed, the drill bit 10 is rotated in a horizontal state, and the lower part is supported by the vertical support 623 installed at the first position. It is possible to keep the horizontal state stable. Therefore, the drill bit 10 is stably lowered vertically.
또한, 상기 드릴비트홀더(611)의 아래쪽에 가이더(220)가 설치된 경우에는 상기 가이더(220)가 하강하는 드릴비트(10)의 몸체부(12)를 감싸주므로 상기 드릴비트(10)가 유동되지 않고 더욱 안정적으로 수직하강할 수 있게 된다.In addition, when the guider 220 is installed below the drill bit holder 611, the drill bit 10 flows because the guider 220 surrounds the body portion 12 of the drill bit 10 that descends. It is possible to descend vertically more stably.
드릴비트(10)를 하강시킨 드릴비트푸쉬바(620)가 원위치로 복귀하면, 압축되었던 탄성부재(611d)의 탄성력에 의해 드릴비트홀더(611)가 상승하게 되며, 이 상태에서 턴테이블(610)이 2단계 회전하면서 드릴비트홀더(611)가 제2위치로 이동하게 된다.When the drill bit push bar 620 having the drill bit 10 lowered returns to its original position, the drill bit holder 611 is raised by the elastic force of the elastic member 611d that has been compressed, and in this state, the turntable 610 During this two-stage rotation, the drill bit holder 611 moves to the second position.
도 24에 도시된 바와 같이, 드릴비트홀더(611)가 제2위치로 이동하게 되면, 드릴비트홀더(611)의 하부로부터 푸쉬로드(641)가 상승하면서 도 25에 도시된 바와 같이 드릴비트홀더(611)에 장착된 드릴비트(10)의 하단을 일정높이로 밀어 올려준다. 그리고 드릴비트홀더(611)의 상부로부터 위치결정링푸쉬바(642)가 단계적으로 수직하강하기 시작한다. 위치결정링푸쉬바(642)가 수직하강을 시작하면, 드릴비트(10)의 절삭선단(11)이 위치결정링(13) 푸쉬바의 저면에 형성된 삽입홈(642a)으로 삽입됨과 아울러 드릴비트(10)의 하단이 푸쉬로드(641)에 의해 지지되고 있는 상태이므로 위치결정링(13)이 위치결정링푸쉬바(642)와 접촉되면서 아래로 밀려 이동하게 된다.As shown in FIG. 24, when the drill bit holder 611 is moved to the second position, the drill bit holder as shown in FIG. 25 while the push rod 641 is raised from the lower part of the drill bit holder 611. 611 pushes the lower end of the drill bit 10 mounted to a certain height. Then, the positioning ring push bar 642 starts to vertically descend from the top of the drill bit holder 611. When the positioning ring push bar 642 starts to fall vertically, the cutting edge 11 of the drill bit 10 is inserted into the insertion groove 642a formed at the bottom of the positioning ring 13 push bar, and the drill bit Since the lower end of the (10) is supported by the push rod 641, the positioning ring 13 is pushed down while being in contact with the positioning ring push bar (642).
도 26에 도시된 바와 같이, 위치결정링(13)이 아래로 이동하게 됨에 따라서, 드릴비트(10)의 절삭선단(11)은 삽입홈(642a)을 통과하여 위치결정링푸쉬바(642)의 하부에 삽입홈(642a)과 연통되게 형성된 관통공(642b)으로 진입하게 된다. 드릴비트(10)의 절삭선단(11)이 관통공(642b)으로 진입하게 되면, 위치결정링푸쉬바(642)가 단계적으로 하강이동할 때마다 제4광학검사기(630)가 상기 관통공(642b)에 의해 외부로 노출된 드릴비트(10)의 절삭선단(11)을 촬영한다. 제4광학검사기(630)는 촬영한 절삭선단(11)의 위치정보를 위치결정링푸쉬바(642)로 전송한다.As shown in FIG. 26, as the positioning ring 13 moves downward, the cutting tip 11 of the drill bit 10 passes through the insertion groove 642a to locate the positioning ring push bar 642. The through hole 642b is formed to communicate with the insertion groove 642a in the lower portion of the. When the cutting edge 11 of the drill bit 10 enters the through hole 642b, the fourth optical inspector 630 moves the through hole 642b whenever the positioning ring push bar 642 moves downward in steps. The cutting edge 11 of the drill bit 10 exposed to the outside is photographed. The fourth optical inspector 630 transmits the captured position information of the cutting edge 11 to the positioning ring push bar 642.
위치결정링푸쉬바(642)가 단계적으로 하강이동을 함에 따라 드릴비트(10)의 절삭선단(11)은 관통공(642b)의 일측지점으로 접근하게 되는데, 위치결정링푸쉬바(642)의 하단에서부터 관통공(642b)의 일측지점까지의 거리(h)가 드릴비트(10)의 절삭선단(11)에서부터 위치결정링(13)의 셋팅지점까지의 거리(h)와 일치하므로, 드릴비트(10)의 절삭선단(11)이 관통공(642b)의 일측지점과 동일수평선상에 위치하게 되면 위치결정링(13)이 셋팅지점에 위치된 것이다.As the positioning ring push bar 642 moves downward in steps, the cutting edge 11 of the drill bit 10 approaches one side of the through hole 642b, and the positioning ring push bar 642 Since the distance h from the lower end to one point of the through hole 642b coincides with the distance h from the cutting edge 11 of the drill bit 10 to the setting point of the positioning ring 13, the drill bit When the cutting edge 11 of (10) is located on the same horizontal line as one side point of the through hole 642b, the positioning ring 13 is positioned at the setting point.
도 26 및 도 27에 도시된 바와 같이, 관통공(642b)의 일측지점과 드릴비트(10)의 절삭선단(11)이 동일수평선상에 위치하게 되면, 제4광학검사기(630)가 위치결정링푸쉬바(642)로 위치정보를 전송하고, 위치결정링푸쉬바(642)는 즉시 하강이동을 중지한다. 그리고 위치결정링푸쉬바(642)와 푸쉬로드(641)는 원래 위치로 복귀한다.As shown in FIGS. 26 and 27, when the one side point of the through hole 642b and the cutting edge 11 of the drill bit 10 are positioned on the same horizontal line, the fourth optical inspector 630 determines the positioning. The position information is transmitted to the ring push bar 642, and the positioning ring push bar 642 immediately stops descending movement. The positioning ring push bar 642 and the push rod 641 return to their original positions.
위치결정링푸쉬바(642)와 푸쉬로드(641)가 원래위치로 복귀하면, 압축되었던 탄성부재(611d)의 탄성력에 의해 드릴비트홀더(611)가 상승한 상태로 턴테이블(610)이 3단계 회전하면서 드릴비트홀더(611)가 제3위치로 이동하게 된다.When the positioning ring push bar 642 and the push rod 641 are returned to their original positions, the turntable 610 is rotated three steps with the drill bit holder 611 being raised by the elastic force of the compressed elastic member 611d. The drill bit holder 611 is moved to the third position.
도 28 및 도 29에 도시된 바와 같이, 드릴비트홀더(611)가 제3위치로 이동하면 제3위치에 설치된 반전로봇(650)이 드릴비트(10)를 척킹한 다음 상승시키고 180°회전시킨 후에 드릴비트홀더(611)에 재장착시킨다. 드릴비트(10)가 반전된 상태로 재장착되면, 턴테이블(610)이 4단계 회전하면서 드릴비트홀더(611)가 제4위치로 이동하게 된다. As shown in FIGS. 28 and 29, when the drill bit holder 611 moves to the third position, an inverted robot 650 installed at the third position chucks the drill bit 10 and then raises and rotates 180 °. The drill bit holder 611 is then remounted. When the drill bit 10 is remounted in an inverted state, the drill bit holder 611 is moved to the fourth position while the turntable 610 is rotated four steps.
도 30에 도시된 바와 같이, 드릴비트홀더(611)가 제4위치로 이동하면, 제4위치에 설치된 드릴비트언로딩유닛(700)이 반전된 상태로 드릴비트홀더(611)에 장착된 드릴비트(10)를 들어올려 드릴비트홀더(611)로부터 탈거시킨 다음에 후속공정으로 이송시켜 준다. 이때, 드릴비트(10)는 반전되어 절삭선단(11)이 아래를 향하고 있는 상태이므로 드릴비트언로딩유닛(700)과 드릴비트(10)의 절삭선단(11)이 서로 접촉할 수가 없으므로 드릴비트(10)는 매우 안전한 상태로 후속공정으로 이송된다.As shown in FIG. 30, when the drill bit holder 611 moves to the fourth position, the drill bit unloading unit 700 installed in the fourth position is mounted in the drill bit holder 611 in an inverted state. The bit 10 is lifted up and removed from the drill bit holder 611 and then transferred to a subsequent process. At this time, since the drill bit 10 is inverted and the cutting end 11 faces downward, the drill bit unloading unit 700 and the cutting end 11 of the drill bit 10 cannot contact each other. (10) is transferred to the subsequent process in a very safe state.
이와 같은 일련의 과정을 거쳐 위치결정링(13)은 자동으로 셋팅되며, 절삭선단과 위치결정링(13)과의 거리가 항상 일정해지므로 드릴비트(10)는 가공드릴에 항상 일정한 위치로 장착될 수 있게 된다. 따라서, 인쇄회로기판상에 가공되는 관통공은 항상 일정한 깊이로 정밀하게 가공될 수 있게 된다.Through this series of processes, the positioning ring 13 is automatically set, and the distance between the cutting edge and the positioning ring 13 is always constant, so that the drill bit 10 is always mounted at a constant position on the machining drill. It becomes possible. Therefore, the through hole processed on the printed circuit board can always be precisely processed to a certain depth.
아울러, 턴테이블(610)이 지속적으로 회전하고 있으므로 이와 같은 셋팅작업은 연속적으로 이루어지게 된다.In addition, since the turntable 610 is constantly rotating, such a setting operation is performed continuously.
한편, 위치결정링(13)의 셋팅이 완료된 드릴비트(10)는 드릴비트언로딩로봇(700)의 제2언로딩부(720)에 의해 작업테이블(610)로부터 탈착된 후 드릴비트 보관함(B)으로 이송된다.On the other hand, after the setting of the positioning ring 13, the drill bit 10 is removed from the worktable 610 by the second unloading unit 720 of the drill bit unloading robot 700, the drill bit storage box ( Transferred to B).
본 발명은 상기와 같은 일련의 과정을 반복하면서 드릴비트(10)의 재연마를 연속적으로 수행하게 된다.The present invention continuously performs the regrinding of the drill bit 10 while repeating the above series of processes.
이와 같이, 도면을 참조하여 본 발명의 바람직한 실시예에 대해 상술하였으나 본 발명은 전술한 실시예에 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진자가 본 발명의 사상을 벗어나지 않고 변형 가능하며, 이러한 변형은 본 발명의 권리범위에 속할 것이다.As described above, preferred embodiments of the present invention are described above with reference to the drawings, but the present invention is not limited to the above-described embodiments, and those skilled in the art may modify the present invention without departing from the spirit of the present invention.
