JP 2008-130851 A JP 2009-158557 A

  In the feeder mounting structure of Patent Document 1 described above, the feeder can be positioned in the front-rear direction by pressing the feeder forward by the clamp member. However, for the left-right positioning of the feeder, the guide rail on the lower surface side of the feeder is mounted on the feeder. Since it is only inserted into the guide groove of the mounting table, the lateral displacement of the feeder occurs within the range of play (gap) between the side surface of the guide rail and the edge of the guide groove, and the lateral displacement of this feeder This is a lateral displacement of the component suction position of the suction nozzle of the electronic component mounting machine, which is a cause of lowering the stability of the component suction operation of the suction nozzle. With recent miniaturization of electronic components, it is necessary to reduce the lateral displacement of the feeder (the lateral displacement of the component suction position).

  As a countermeasure, it is conceivable to reduce the play between the side surface of the guide rail and the edge of the guide groove, but if this play is reduced, the guide rail is moved along the guide groove when the feeder is attached or detached. The frictional resistance acting on the side surface of the guide rail is increased, and the attachment / detachment workability of the feeder is deteriorated. Therefore, in order to ensure the attachment / detachment workability of the feeder, it is necessary to secure a certain amount of play between the side surface of the guide rail and the edge of the guide groove.

  Further, as described in Patent Document 2 (Japanese Patent Application Laid-Open No. 2009-158557), two positioning pins are provided so as to protrude downward on the lower surface side of the feeder, and two positioning holes are provided in the feeder mounting table. When the feeder is mounted on the feeder mounting table of the electronic component mounting machine, the two positioning pins of the feeder are inserted into the two positioning holes of the feeder mounting table to prevent the lateral displacement of the feeder. There is.

  However, in the technique of Patent Document 2, since the positioning pin is fixed to the lower surface side of the feeder so as to protrude downward, when the feeder is slid on the feeder mounting table when the feeder is attached or detached, the feeder is moved downward from the feeder. The positioning pins projecting in the way obstruct the sliding movement, making it difficult to smoothly slide the feeder and deteriorating the detachability of the feeder.

  Therefore, the problem to be solved by the present invention is to provide a feeder mounting structure capable of improving the position accuracy of the feeder in the left-right direction when the feeder is mounted while ensuring the detachability of the feeder.

In order to solve the above-mentioned problem, the invention according to claim 1 is characterized in that the guide rail on the lower surface side of the feeder is inserted into the guide groove of the feeder mounting table of the electronic component mounting machine, and the clamp member provided on the feeder In the feeder mounting structure in which the feeder is clamped by pressing forward and clamping the feeder to the feeder mounting table in the front-rear direction, the positioning member for positioning the feeder in the left-right direction is disposed on the feeder. A projecting position for positioning the feeder in the left-right direction by projecting the positioning member downward from the feeder and being fitted into a fitting portion of the feeder mounting table, and the positioning member. It provided the operating member to move between a retracted position for retracting withdrawn upwardly from the fitting portion Furthermore, the clamp member is provided movably between a clamp position for pressing the feeder forward and an unclamp position for releasing the forward press of the feeder, and the operating means moves the clamp member. In conjunction with the movement of the clamp member to the clamp position, the positioning member moves to the protruding position, and the clamp member moves to the unclamp position. The positioning member is configured to move to the retracted position.

  In this configuration, when the feeder is attached to the feeder mounting table of the electronic component mounting machine, the clamp member pushes the feeder forward and clamps it, and the positioning member is moved to the protruding position and fitted into the fitting portion of the feeder mounting table. By inserting the feeder, the feeder can be attached in a state of being positioned in the front-rear direction and the left-right direction. Thereby, the position accuracy in the left-right direction of the feeder (position accuracy in the left-right direction of the component suction position) can be improved, and the stability of the component suction operation of the suction nozzle can be improved. Moreover, when the feeder is attached or detached, the positioning member is pulled out from the fitting portion of the feeder mounting table and retracted to the retracted position, so that the positioning member does not interfere with the sliding movement when the feeder is attached or detached, and the feeder slides smoothly. It can be moved, and the attachment / detachment workability of the feeder is not impaired.

In this case, ramp member includes a clamping position for pressing the feeder to the front, movably provided between an unclamped position to release the pressing forward of the feeder, operating means for operating the movement of the positioning member, The positioning member is also used in conjunction with the movement of the clamp member. The positioning member moves to the protruding position in conjunction with the movement of the clamping member to the clamping position, and the positioning member in conjunction with the movement of the clamping member to the unclamping position Is configured to move to the retracted position, so that when the feeder is attached / detached, the operator can move both the clamp member and the positioning member to the proper position by operating only one operation member. , The operator can save time and effort to operate the clamp member and positioning member separately, can further improve the detachment workability of the feeder, It can prevent erroneous operation of the-decided Me member.

In the present invention, the fitting portion for fitting the positioning member to the feeder mounting table may be formed separately from the guide groove. However, as in claims 2 and 3, a part of the guide groove of the feeder mounting table. May be used as a fitting portion into which the positioning member is fitted. In this way, it is not necessary to newly form a fitting portion for the positioning member on the feeder mounting table, and the present invention can be directly applied to a feeder mounting table similar to the conventional one.

  In addition, since the feeder is pressed forward (back wall of the feeder mounting table) by the clamp member and the front end of the feeder is positioned, the rear end of the feeder is the guide rail side surface and the guide groove with the front end of the feeder as a fulcrum. In consideration of the characteristic of being easily displaced in the left-right direction within the range of play with the edge of the feeder, as in claim 4, the portion of the feeder mounted on the feeder mounting table in the front-rear direction The positioning member may be disposed behind the center. If it does in this way, the positioning state of the front-back direction of a feeder and the left-right direction can be stably hold | maintained by the front-end part side and positioning member of a feeder.

Hereinafter, an embodiment embodying a mode for carrying out the present invention will be described.
As shown in FIG. 1, the electronic component mounting machine is provided with a mounting head 12 that holds the suction nozzle 11 downward, and a plurality of feeders 13 are placed in a horizontal row below the mounting head 12. A feeder mounting table 14 is provided.

  The feeder 13 is a tape feeder in which a reel 15 around which a component supply tape holding a large number of electronic components is wound is detachably mounted. The feeder 13 is a drive source for pitch-feeding the component supply tape. A motor (not shown) and a control unit (not shown) for controlling the motor are incorporated, and the control unit stores a management information such as feeder identification information (ID) (not shown). It has.

  A connector 16 for both communication and power supply is provided at the front end portion (insertion side end portion) of the feeder 13, and this connector 16 is inserted and connected to a connector 17 provided on the back wall 14 a of the feeder mounting base 14. In addition to supplying power to the feeder 13 from the electronic component mounter side, control signals (component request signal, component supply completion signal, etc.) between the control unit of the feeder 13 and the control unit (not shown) of the electronic component mounter ) And feeder identification information (ID) and other management information are transmitted or received. In place of the mechanically connected connectors 16 and 17, a non-contact communication interface capable of non-contact communication or a non-contact power supply interface capable of non-contact power supply may be used.

  In addition, guide pins 41 and 42 for guiding insertion and connection of the connectors 16 and 17 are provided on both the upper and lower sides of the connector 16 in the front end portion of the feeder 13, and the feeder 13 placed on the feeder placing table 14. By inserting the guide pins 41 and 42 into the positioning holes 43 and 44 of the back wall 14a of the feeder mounting table 14, the front end of the feeder 13 is positioned on the feeder mounting table 14. .

  A guide groove 18 (see FIG. 4) having an inverted T-shaped cross section for vertically supporting the feeder 13 is provided on the upper surface of the feeder mounting table 14, and an inverted T-shaped cross section provided on the lower surface side of the feeder 13. When the guide rail 19 is inserted into the guide groove 18 from the front side, the feeder 13 is supported on the feeder mounting table 14 in a vertically placed state, and the clamp member 21 provided on the feeder 13 is connected to the feeder mounting table 14. The feeder 13 is positioned in the front-rear direction on the feeder mounting table 14 and can be attached / detached by fitting into the clamp hole 22 and pressing the feeder 13 forward (on the rear wall 14a side of the feeder mounting table 14) and clamping. It is supposed to be attached to.

  As shown in FIGS. 2 and 3, the clamp member 21 is rotatably connected to one end of a “<”-shaped lever 23 that rotates about a shaft 20 via a shaft 24. A link 26 is rotatably connected to the other end via a shaft 25. The link 26 moves in the left-right direction in conjunction with the operation of an operation lever 27 (see FIG. 1) that is an operation member provided on the upper front side of the feeder 13, and in conjunction with this, the lever 23 supports the shaft 20 as a fulcrum. And the clamp member 21 is moved up and down. Accordingly, when the operation lever 27 is operated to the clamp position (the position indicated by the solid line in FIG. 1), as shown in FIG. 2, the clamp member 21 is fitted into the clamp hole 22 of the feeder mounting table 14 and the feeder 13 is moved forward ( When the operation lever 27 is operated to the unclamping position (the position indicated by the two-dot chain line in FIG. 1), the clamp member 21 is moved to the unclamping position (the position indicated by the two-dot chain line in FIG. 1). It becomes an unclamped state where it is lifted obliquely upward from the clamp hole 22 and the clamped state (the state of pressing the feeder 13 forward) is released.

  At least one of the clamp member 21, the lever 23, and the link 26 is provided with a biasing means (not shown) such as a spring for biasing the clamp member 21 in the clamping direction (diagonally downward). The clamp state is held by the biasing force of the means. The clamp member 21 is formed with a long hole 29 that regulates the moving direction of the clamp member 21 in a slanting vertical direction. The long hole 29 is fitted into the guide shaft 30 so that the moving direction of the clamp member 21 is slanted. It is regulated in the vertical direction.

  In the vicinity of the lever 23, a safety switch 31 for detecting switching between clamping and unclamping is provided. As shown in FIG. 2, the clamping member 21 is in a clamping state in which the clamping member 21 is fitted in the clamping hole 22 of the feeder mounting table 14. Then, the lever 23 pushes the actuator 32 of the safety switch 31 to switch the safety switch 31 to the ON state (detection state), and the clamp member 21 is lifted obliquely upward from the clamp hole 22 as shown in FIG. In the unclamped state, the lever 23 is separated from the actuator 32 of the safety switch 31, and the safety switch 31 is switched to the off state (non-detection state). As a result, the control unit of the feeder 13 and / or the control unit of the electronic component mounting machine can determine whether the safety switch 31 is on or off, thereby determining whether it is in the clamped state or the unclamped state.

  The feeder 13 is provided with a positioning pin 33 (positioning member) for positioning the feeder 13 in the left-right direction so as to be movable up and down in the vicinity of the clamp member 21. The positioning pin 33 is connected to a rod 35 of a spring plunger 34 fixed downward, and is biased downward by a spring (not shown) inside the spring plunger 34. An engagement flange 36 is provided on the upper portion of the positioning pin 33 (or the rod 35 of the spring plunger 34), and an engagement piece 37 formed on the clamp member 21 is engaged with the engagement flange 36 from below. The positioning pin 33 moves up and down in conjunction with the up and down movement of the clamp member 21. The positioning pin 33 may be cylindrical or may be formed of a prismatic member such as a quadrangular section.

  In the present invention, a fitting portion for fitting the positioning pin 33 into the feeder mounting table 14 may be formed separately from the guide groove 18, but in this embodiment, one of the guide grooves 18 of the feeder mounting table 14 is formed. The portion is used as a fitting portion into which the positioning pin 33 is fitted.

  As shown in FIG. 2, when the clamp member 21 is lowered to the clamp position, the engagement piece 37 of the clamp member 21 that has been pushing up the engagement flange 36 of the positioning pin 33 is also lowered, so that the inside of the spring plunger 34 As a result, the positioning pin 33 is pushed down to the lower protruding position and is fitted into the guide groove 18 (see FIG. 4). The lower end portion of the positioning pin 33 is formed in a tapered shape so as to be easily fitted into the guide groove 18.

  As shown in FIG. 4, the diameter of the positioning pin 33 is slightly smaller than the opening width (groove width) of the guide groove 18 and larger than the thickness dimension of the guide rail 19. As a result, when the positioning pin 33 is fitted into the guide groove 18, the play (gap) between the positioning pin 33 and the edge of the guide groove 18 causes the side surface of the guide rail 19 and the edge of the guide groove 18. Thus, the feeder 13 is positioned in the left-right direction. In this state, even if an external force is applied to the feeder 13 from the left-right direction, the lateral displacement of the feeder 13 (the lateral displacement of the component suction position) is reduced, and the lateral accuracy of the component suction position is improved. improves.

  The position of the positioning pin 33 may be any position as long as it is above the guide groove 18 of the feeder mounting table 14. In this embodiment, the portion of the feeder 13 that is mounted on the feeder mounting table 14. The positioning pin 33 is arranged behind the center in the front-rear direction. This is because the clamp member 21 pushes the feeder 13 forward (the rear wall 14a of the feeder mounting table 14) and the front end of the feeder 13 is positioned by the guide pins 41 and 42, so that the front end of the feeder 13 is a fulcrum. Thus, the characteristic that the rear end portion side of the feeder 13 is easily displaced in the left-right direction within the range of play between the side surface of the guide rail 19 and the edge portion of the guide groove 18 is considered. Therefore, if the positioning pin 33 is disposed on the rear side of the center of the feeder 13 on the feeder mounting table 14 in the front-rear direction, the front end portion side and the rear positioning pin 33 of the feeder 13 The positioning state of the feeder in the front-rear direction and the left-right direction can be stably maintained.

Next, a method for attaching / detaching the feeder 13 to / from the feeder mounting table 14 will be described.
When attaching the feeder 13 to the feeder mounting table 14, first, the operation lever 27 is operated to the unclamping position (the position of the two-dot chain line in FIG. 1). As a result, as shown in FIG. 3, the clamp member 21 is moved to the upper unclamping position and retracted into the feeder 13, and the positioning pin 33 is moved by the engagement piece 37 of the clamp member 21 to the spring plunger. The state is pushed up to the retracted position against the urging force of 34. Accordingly, the clamp member 21 and the positioning pin 33 are retracted to a position that does not interfere with the attachment / detachment of the feeder 13.

  In this state, the guide rail 19 on the lower surface side of the feeder 13 is inserted into the guide groove 18 of the feeder mounting table 14 from the front side, and the guide pins 41 and 42 at the front end of the feeder 13 are inserted into the rear wall 14a of the feeder mounting table 14. The connector 16 of the feeder 13 is inserted and connected to the connector 17 of the back wall 14a of the feeder mounting base 14 while being inserted into the positioning holes 43 and 44 and positioning the front end portion of the feeder 13.

  By this operation, when the front end portion of the feeder 13 comes into contact with the back wall 14a of the feeder mounting table 14, the operation lever 27 is operated to the clamp position (the position indicated by the solid line in FIG. 1). As a result, as shown in FIG. 2, the clamp member 21 is fitted into the clamp hole 22 of the feeder mounting table 14, and the feeder 13 is pressed forward (on the rear wall 14 a side of the feeder mounting table 14) and clamped. In the process, the lever 23 pushes the actuator 32 of the safety switch 31 so that the safety switch 31 is turned on, and when the clamp member 21 is lowered to the clamp position, the engaging flange 36 of the positioning pin 33 until then. Since the engaging piece 37 of the clamp member 21 that has pushed up also descends, the positioning pin 33 is pushed down to the downward projecting position by the urging force of the spring plunger 34 and fits into the guide groove 18 (FIG. 4). reference). Thereby, the feeder 13 is attached in the state positioned on the feeder mounting base 14 in the front-rear direction and the left-right direction.

  On the other hand, when removing the feeder 13 attached on the feeder mounting base 14, first, the operation lever 27 is operated to the unclamping position (the position of the two-dot chain line in FIG. 1). As a result, as shown in FIG. 3, the clamp member 21 is lifted obliquely upward from the clamp hole 22 to be in an unclamped state in which the clamped state (the state of pressing the feeder 13 forward) is released. Is separated from the actuator 32 of the safety switch 31 and the safety switch 31 is switched to the OFF state, and the positioning pin 33 is pushed up to the retracted position against the urging force of the spring plunger 34 by the engagement piece 37 of the clamp member 21. It becomes a state. Accordingly, the clamp member 21 and the positioning pin 33 are retracted to a position that does not interfere with the attachment / detachment of the feeder 13. When the feeder 13 is pulled out in this state, the guide rail 19 on the lower surface side of the feeder 13 is extracted from the guide groove 18 of the feeder mounting table 14, and the feeder 13 is removed from the feeder mounting table 14.

  In the present embodiment described above, when the feeder 13 is attached to the feeder mounting table 14, the clamp 13 pushes the feeder 13 forward and clamps, and the positioning pin 33 protrudes downward to guide the feeder mounting table 14. By fitting in the groove 18, the feeder 13 can be attached in a state of being positioned in the front-rear direction and the left-right direction. Thereby, the position accuracy of the feeder 13 in the left-right direction (position accuracy in the left-right direction of the component suction position) can be improved, and the stability of the component suction operation of the suction nozzle 11 can be improved. Moreover, when the feeder 13 is attached / detached, the positioning pin 33 is pushed up from the guide groove 18 of the feeder mounting table 14 and retracted to the retracted position, so that the positioning pin 33 does not interfere with the sliding movement when the feeder 13 is attached / detached. The feeder 13 can be smoothly slid and the detachability of the feeder 13 is not impaired.

  Moreover, in this embodiment, the operation lever 27 for operating the movement of the clamp member 21 is also used as an operation means for operating the movement of the positioning pin 33, and positioning is performed in conjunction with the movement of the clamp member 21 to the clamp position. The pin 33 moves to the protruding position, and the positioning pin 33 moves to the retracted position in conjunction with the movement of the clamp member 21 to the unclamping position. By only operating the operation lever 27, both the clamp member 21 and the positioning pin 33 can be moved to appropriate positions, and the labor of the operator separately operating the clamp member 21 and the positioning pin 33 can be saved. In addition, it is possible to further improve the attaching / detaching workability of the feeder 13 and to prevent erroneous operation of the positioning pin 33.

  However, in the present invention, the operating means for operating the movement of the positioning pin 33 and the means for operating the movement of the clamp member 21 may be provided separately. Even in this case, the intended purpose of the present invention is sufficient. Can be achieved.

  Further, in this embodiment, a part of the guide groove 18 of the feeder mounting table 14 is used as a fitting portion into which the positioning pin 33 is fitted, so that the positioning of the positioning pin 33 on the feeder mounting table 14 is performed. There is no need to newly form a joint portion, and there is an advantage that the present invention can be implemented as it is on the feeder mounting table 14 similar to the conventional one.

  However, in the present invention, a fitting portion for fitting the positioning pin 33 into the feeder mounting table 14 may be formed separately from the guide groove 18, and even in this case, the intended purpose of the present invention is sufficiently achieved. it can.

  In addition, the present invention is not limited to the configuration of the present embodiment. For example, the configuration in which the movement of the clamp member 21 and the movement of the positioning pin 33 are interlocked, or the positioning pin 33 is moved up and down. It is possible to implement various modifications without departing from the spirit of the invention.
