Description

  The present invention relates to a laser processing head and an optical fiber unit remote attachment / detachment device that are used to enable a laser processing head and an optical fiber unit to be attached / detached by a remotely operated manipulator.

  As one of the laser processing machines, there is a type in which a laser processing head is connected to a laser oscillation device via an optical fiber cable that guides laser light (for example, see Patent Document 1).

  When starting to use this type of laser processing machine, it is necessary to newly connect an optical fiber unit provided at the tip of the optical fiber cable to the laser processing head. Also, when replacing either the laser processing head or the optical fiber cable with a new one after the optical fiber unit is already connected to the laser processing head, the laser processing head and the optical fiber unit should be attached or detached. Is needed.

  It is conceivable to use a connector with a lock mechanism such as a quick disconnect connector (QD connector) at the connection portion between the laser processing head and the optical fiber unit in order to facilitate the connection work. In this case, the operation of releasing the lock by the lock mechanism and the operation of inserting / removing the connector plug into / from the connector mount must be performed together.

  By the way, the laser processing machine is used for the operation of cutting a device to be discarded even in an environment where an operator cannot enter such as a high radiation environment.

  For laser processing machines used in such an environment where workers cannot enter, the laser processing head and the optical fiber unit as described above need to be attached / detached by remote operation using a remote manipulator. There is.

  One type of remote operation type manipulator is a master-slave manipulator (master-slave manipulator, hereinafter referred to as MSM). This MSM is known as a remote operation type manipulator capable of performing detailed work as compared with a power manipulator.

  However, even if MSM is used, it is difficult to simultaneously perform two operations, that is, an operation of releasing the connector locking mechanism and an operation of inserting / removing the connector plug into / from the connector mount in parallel. .

  Therefore, conventionally, no means has been proposed for enabling the laser processing head and the optical fiber unit to be attached and detached by remote operation using the MSM.

  Further, the connector mount 105 is mounted in a posture in which the connector mount 105 is directed to the other end side in the y-axis direction at a certain part of the mounting surface 18, for example, on one side in the y-axis direction or on both end edges in the y-axis direction. A positioning guide 21 for positioning the laser processing head 101 placed on the mounting surface 18 in the y-axis direction is provided.

  The first laser processing head fixed base 3 having the above configuration places the laser processing head 101 on the mounting surface 18 in the predetermined posture and uses the positioning guide 21 in the y-axis direction of the laser processing head 101. After positioning, by operating the laser processing head fixing clamp 19 using the MSM, the laser processing head 101 can be fixed between the laser processing head fixing clamp 19 and the side pressing member 20. ing.

  Since the second laser processing head fixing base 4 has the same configuration as the first laser processing head fixing base 3, description thereof will be omitted.

  As shown in FIG. 7, the slide table 5 includes two x-axis direction guide rails 22 provided in parallel on the base plate 1, and x-axis direction guides slidably attached to the respective x-axis direction guide rails 22. A block 23, an intermediate plate 24 fixed to the upper side of the two x-axis direction guide blocks 23, and a y-axis direction guide block 25 installed on the upper surface of the intermediate plate 24 with the rail fitting side facing upward. The y-axis direction guide block 25 is supported by a y-axis direction guide rail 26 that is slidably held and fixed to the lower surface of the slide table 5. As a result, the slide table 5 is moved in the x-axis direction and the y-axis direction by sliding the x-axis direction guide block 23 along the x-axis direction guide rail 22 and sliding the y-axis direction guide rail 26 with respect to the y-axis direction guide block 25. It is possible to move to.

  A first tracking table 8 and a second tracking table 9 are arranged on both sides of the slide table 5 in the x-axis direction.

  The first and second tracking tables 8 and 9 are fixed to the x-axis guide block 27 slidably attached to the x-axis direction guide rails 22 and the upper side of the two x-axis direction guide blocks 27. The intermediate plate 28, the y-axis direction guide rail 29 installed on the upper surface of the intermediate plate 28, and the y-axis guide rail 29 slidably attached to the y-axis direction guide rail 29 and fixed to the lower surfaces of the following tables 8 and 9 It is supported individually by the direction guide block 30. As a result, the first and second follow-up tables 8 and 9 have the same movement areas in the x-axis direction and the y-axis direction as the slide table 5.

  Further, through holes 31 penetrating along the x-axis direction are provided at two positions on the both end surfaces in the x-axis direction of the first and second tracking tables 8 and 9 at a certain interval in the y-axis direction. It has been drilled. In each through hole 31, a rod member 32 extending in the x-axis direction installed at a corresponding position on both end surfaces of the slide table 5 in the x-axis direction is inserted and arranged.

  The rod members 32 inserted into the through holes 31 of the first follower table 8 are connected by connecting members 33 at projecting ends protruding from the first follower table 8. Furthermore, each rod member 32 is disposed between the side surfaces of the slide table 5 and the first follower table 8 facing each other in the longitudinal direction, and the first follower table 8 and the connecting member 33 are opposed to each other. The spring member 34 is attached to the outer periphery of the place arrange | positioned between side surfaces in the state compressed a little in the axial direction.

  Similarly, each rod member 32 inserted into the through hole of the second follower table 9 is connected by a connecting member 33 at the projecting ends protruding from the second follower table 8. Further, each rod member 32 is disposed between the side surfaces of the slide table 5 and the second tracking table 9 facing each other in the longitudinal direction, and the second tracking table 9 and the connecting member 33 are opposed to each other. The spring member 34 is attached to the outer periphery of the place arrange | positioned between side surfaces in the state compressed somewhat in the x-axis direction.

  Thereby, since the 1st follow-up table 8 and the 2nd follow-up table 9 are connected to the slide table 5 via each rod member 32 and the spring member 34, the slide table 5 can be moved in the x-axis direction and the y-axis direction. When moved, basically, the first tracking table 8 and the second tracking table 9 move in the x-axis direction and the y-axis direction following the movement. At this time, the first follower table 8 and the second follower table 9 are allowed to be slightly displaced relative to the slide table 5 in the x-axis direction by the amount of elastic deformation of the spring member 34. The configuration is such that the connector plug of the optical fiber unit 102 fixed to the first optical fiber unit fixing base 10a on the first tracking table 8 and the second optical fiber fixing base 10b on the second tracking table 9 is used. When the axial center position of 104 and the axial center position of the connector mount 105 of the laser processing head 101 fixed to the first or second laser processing head fixing bases 3 and 4 are slightly deviated due to individual differences or design errors. Even so, when the connector plug 104 is inserted into the connector mount 105, the position of the connector plug 104 can be automatically adjusted following the position of the connector mount 105.

  A frame 35 extending in the y-axis direction is attached to the upper side of the first tracking table 8.

  As shown in FIGS. 9 (a) and 9 (b), the frame 35 has a vertical surface in the x-axis direction at two locations, one end portion in the y-axis direction and a location near one end in the y-axis direction at a certain distance from the frame 35. Are provided with support plate portions 36 and 37 having a certain height dimension.

  Between each support plate part 36 and 37, the two guide shafts 38 extended along the y-axis direction are attached in parallel with a certain gap in the x-axis direction.

  A linear bush 38a is attached to the outer periphery of each guide shaft 38 so as to be slidable in the y-axis direction. Each linear bush 38a is fixed to the lower end portion of the first optical fiber unit fixing base 10a. Thus, the first optical fiber unit fixed base 10a is slidable in the y-axis direction along the guide shaft 38.

  Near the other end of the frame 35 in the y-axis direction, a first optical fiber unit fixing base operating lever 12a having a handle 39 that can be gripped by the MSM is connected to one end in the x-axis direction in the horizontal plane via the support member 40. It is provided so that it can turn from a posture facing toward the side to a posture facing toward the other end.

  The first optical fiber unit fixed base 10a has one end in the longitudinal direction of the connecting member 41 extending in the y-axis direction attached to the side surface on the other end side in the y-axis direction. The other end of the connecting member 41 in the longitudinal direction is connected to the base end of the first optical fiber unit fixing base operating lever 12a via a toggle mechanism 42. Accordingly, when the first optical fiber unit fixed base 10a is operated by the MSM so that the first optical fiber unit fixed base operating lever 12a is directed to one end side in the x-axis direction, the first optical fiber unit fixed base 10a is indicated by a two-dot chain line in FIG. As described above, it is moved to the one end side in the y-axis direction on the frame 35 fixed to the first tracking table 8. The arrangement of the first optical fiber unit fixed base 10a in this state is hereinafter referred to as a connection position.

  On the other hand, when the first optical fiber unit fixing base 10a is operated by the MSM so that the first optical fiber unit fixing base operating lever 12a is directed to the other end side in the x-axis direction, as shown by a solid line in FIG. It is moved to the other end side in the y-axis direction. The arrangement of the first optical fiber unit fixed base 10a in this state is hereinafter referred to as a separation position.

  The movement stroke in the y-axis direction from the connection position to the separation position of the first optical fiber unit fixed base 10a is such that the connector plug 104 of the optical fiber unit 102 is inserted into the connector mount 105 of the laser processing head 101. A portion related to the locking of the connector plug 104, for example, a locking groove is located at a position facing the locking member on the connector mount 105 side, and deviates from the facing position to the plug insertion port 106 side of the connector mount 105. It is set corresponding to the distance from the position where the dimension is extracted.

  As shown in FIGS. 9A, 9B, and 9C, on the outer side (one end side in the y-axis direction) of the support plate portion 36 at one end portion in the y-axis direction of the frame 35, the unlocking sleeve 107 of the connector mount 105 is provided. An unlocking guide 13a for pressing against is arranged. The unlocking guide 13a includes a semicircular cutout 43 having an inner diameter similar to the inner diameter of the unlocking sleeve 107 on the upper part of the plate member arranged along a vertical plane parallel to the x-axis direction. As a result, the lock release guide 13 a is configured so that the peripheral edge of the notch 43 can be brought into contact with the end surface of the lock release sleeve 107.

  The support plate portion 36 is linearly penetrated in the y-axis direction at locations where the guide shafts 38 for the first optical fiber unit fixing base 10a do not interfere with each other, for example, at two locations near both ends in the x-axis direction. A bush 44 is attached. In each linear bush 44, two guide shafts 45 in the y-axis direction are attached so as to be slidable and attached to corresponding portions of the lower end portion of the surface on the other end side in the y-axis direction of the unlocking guide 13a. As a result, the lock release guide 13 a is held by the frame 35 so as to be movable in the y-axis direction via the guide shaft 45 and the linear bush 44.

  Furthermore, one end of a stroke shaft 46 extending in the y-axis direction is attached to the center of the lower end of the surface on the other end side in the y-axis direction of the unlocking guide 13a.

  At the other end in the y-axis direction of the frame 35, a first connector mount unlocking operation lever 14a having a handle 47 that can be gripped by the MSM is provided on one end side in the x-axis direction in the horizontal plane via the support member 48. It is provided so as to be able to turn from a posture facing toward the other end to a posture facing toward the other end.

  The other end portion of the stroke shaft 46 is connected to the proximal end portion of the first connector mount unlocking operation lever 14 a via a toggle mechanism 49. Accordingly, when the first connector mount unlocking operation lever 14a is operated toward one end in the x-axis direction by the MSM, the unlocking guide 13a is moved in the y-axis direction so as to be separated from the support plate portion 36 of the frame 35. Extruded to one end. On the other hand, when the first connector mount unlocking operation lever 14a is operated so as to face the other end side in the x-axis direction by the MSM, the unlocking guide 13a is moved in the y-axis direction so as to be close to the support plate portion 36 of the frame 35. It is pulled back to the other end side.

  Therefore, the lock release guide 13a is disposed in a position close to the connector mount 105 of the laser processing head 101 on the other end side in the y-axis direction by operating the first connector mount unlocking operation lever 14a. When pushed to one end in the axial direction, the lock release sleeve 107 of the connector mount 105 can be pushed toward one end in the y-axis direction to release the lock.

  By the way, in the operation of pushing the unlocking sleeve 107 with the unlocking guide 13a, if the unlocking sleeve 107 reaching the end of the movable range is further pushed in, the unlocking sleeve 107, the connector mount 105, and further the laser An excessive force is applied to the processing head 101.

  Therefore, the stroke shaft 46 is provided with a buffer mechanism 50 at an intermediate position in the longitudinal direction for preventing the lock release sleeve 107 from being forced by the lock release guide 13a.

  The shock absorbing mechanism 50 has a two-part structure in which the stroke shaft 46 is divided at a middle portion in the longitudinal direction with a certain gap therebetween, and a pair of opposing plate members 51 are attached to the divided ends. Yes. Further, a plurality of guide rods 52 along the y-axis direction are attached to one plate member 51, and each guide rod 52 is a guide hole (not shown) drilled at a corresponding portion of the other plate member 51. Is inserted. A stopper 53 is attached to the protruding end of each guide rod 52. Further, a spring member 54 that is slightly stronger than the spring member that urges the unlocking sleeve 107 by the connector mount 105 is interposed between the plate members 51.

  Thus, from the state shown by the solid line in FIGS. 9A and 9C, as shown by the two-dot chain line, the unlocking guide 13a is operated via the stroke shaft 46 by the operation of the first connector mount unlocking operating lever 14a. When the lock release sleeve 107 is pushed to the end of the movable range when the lock release sleeve 107 is pushed out to one end side in the y-axis direction and the lock release sleeve 107 of the connector mount 105 is unlocked, the stroke shaft 46 is buffered thereafter. Since the spring member 54 of the mechanism 50 is contracted, excessive push-in of the unlocking sleeve 107 is prevented.

  The support plate portion 37 near the other end in the y-axis direction of the frame 35 is provided with a linear bush 55 at a position where the stroke shaft 46 penetrates so as to receive the stroke shaft 46. Further, the stroke shaft 46 is supported at a portion near the other end in the y-axis direction of the stroke shaft 46 by a support member 56 with a linear bush 57 provided on the frame 35 so that the stroke shaft 46 is supported on both sides of the buffer mechanism 50. You may do it.

  The first optical fiber unit fixed base 10a and the support member 40 of the first optical fiber unit fixed base operating lever 12a are provided with a notch at the lower end portion so as to avoid interference with the stroke shaft 46.

  As shown in FIGS. 8 (a) and 8 (b), the first optical fiber unit fixing base 10a is fitted on the upper surface thereof with a portion near the lower end of the optical fiber unit 102 placed from above, so that the optical fiber unit 102 is fitted. In order to constrain displacement in the y-axis direction, an uneven shape is provided.

  The first optical fiber unit fixing clamp 11a provided on the upper side of the first optical fiber unit fixing base 10a includes a gate-shaped frame 58 disposed so as to straddle the upper side of the first optical fiber unit fixing base 10a in the x-axis direction. .

  One leg of the frame 58 has a lower end attached to one side surface in the x-axis direction of the first optical fiber unit fixed base 10 a so as to be rotatable in the vertical direction via a hinge 59.

  A snap lock 60 is attached to the outer surface of the other leg portion of the frame 58 and the other side surface of the first optical fiber unit fixing base 10a in the x-axis direction. The snap lock 60 has a size and shape that can be locked and unlocked by the MSM.

  Further, a pressing member 61 is attached to the inside of the upper end portion of the frame 58 so as to be lifted and lowered by lifting means (not shown). On the upper side of the upper end of the frame 58, a handle 62 for operating the elevating means is provided in a shape that can be operated by the MSM, for example, a cross shape.

  The pressing member 61 may be provided with a concavo-convex shape corresponding to the upper shape of the optical fiber unit 102 on the lower surface side.

  When the optical fiber unit 102 is fixed using the first optical fiber unit fixing base 10a having the above-described configuration, the first optical fiber unit fixing clamp 11a is unlocked in advance in a state where the lock by the snap lock 60 is released. The frame 58 is opened.

  Next, the optical fiber unit 102 is placed on the first optical fiber unit fixing base 10a. At this time, the portion near the lower end of the optical fiber unit 102 is fitted into the uneven shape of the first optical fiber unit fixing base 10a.
