Description

  The present invention relates to a component suction nozzle applied to a component transport device that sucks and transports a component, a component transport device including the component suction nozzle, and a component mounting apparatus including the component transport device.

  2. Description of the Related Art There is known a component conveying apparatus that has a head that can move in the vertical direction and the horizontal direction, and that picks up a component by a component suction nozzle provided in the head and conveys the component to a predetermined position. This component conveying apparatus is widely used in a component mounting apparatus that takes out a component from a component supply unit and conveys and mounts the component on a substrate such as a printed circuit board.

  In the component mounting apparatus, the nozzle is provided downward, and holds the component by sucking the upper surface of the component. The head is generally provided so as to be rotatable about a vertical axis. Thus, by rotating the nozzle together with the head, it is possible to change the suction posture of the component around the vertical axis.

  In recent years, with the diversification of mounted components, in component mounting apparatuses, for example, it is required to suck a component placed sideways with a nozzle and change the component to a standing posture and mount it on a substrate. For this reason, the component mounting apparatus is required to change the posture of the component adsorbed by the nozzle around the vertical axis as well as around the horizontal axis.

  Here, as a mechanism for changing the posture of the component around the horizontal axis, for example, a mechanism described in Patent Document 1 or Patent Document 2 can be considered. That is, it can be considered that the nozzle supported by the head is driven by an air cylinder or a servo motor so as to be rotatable around a horizontal axis.

  However, if a dedicated drive source (air cylinder or servo motor) for driving the nozzle around the horizontal axis is provided, it will lead to an increase in the size of the head and, in turn, an increase in the size of the component mounting device, and also to increase the cost. It is not desirable.

Then, after the mounting operation, the board P is unloaded to the left side (X2 direction side) of FIGS.

  The component supply units 3 and 4 are disposed on both sides (Y direction both sides) of the substrate transport mechanism 2. Among the component supply units 3 and 4, the component supply unit 4 located on the rear side (Y1 side) of the component mounting apparatus M has a plurality of tape feeders 4a arranged along the conveyor 2a. Each tape feeder 4a supplies small pieces of electronic components (chip components) such as ICs, transistors, and capacitors. On the other hand, trays 3a and 3b are set in the component supply unit 3 on the rear side (Y2 side) of the component mounting apparatus M. The trays 3a and 3b include package-type electronic components such as QFP (Quad Flat Package) and BGA (Ball Grid Array), and leads such as connectors, which are inserted into a substrate and the like. In this state, the electronic components are supplied with the leads that tend to be in the horizontal direction.

  The head unit 5 takes out components from the component supply units 3 and 4 and mounts them on the substrate P, and is disposed above the substrate transport mechanism 2 and the component supply units 3 and 4.

  The head unit 5 is movable in the X direction and the Y direction within a certain region by the head unit driving mechanism. The head unit drive mechanism is fixed to a pair of elevated frames provided on the base 1, and is supported by the pair of fixed rails 8 and extends in the X direction. A member 11 and a ball screw shaft 9 screwed into the unit support member 11 and driven by a Y-axis servomotor 10 are included. The head unit drive mechanism is fixed to the unit support member 11 and supports the head unit 5 so as to be movable in the X direction. The head unit drive mechanism is screwed into the head unit 5 so as to drive the X-axis servo motor 15 as a drive source. And a ball screw shaft 14 driven as follows. In other words, the head unit driving mechanism moves the head unit 5 in the X direction via the ball screw shaft 14 by driving the X axis servo motor 15, and via the ball screw shaft 9 by driving the Y axis servo motor 10. The unit support member 11 is moved in the Y direction. As a result, the head unit driving mechanism moves the head unit 5 in the X direction and the Y direction within a certain region. In this example, the head unit 5 and the head unit driving mechanism correspond to the component conveying device of the present invention.

  The head unit 5 includes a plurality of (6 in this example) shaft-shaped heads 16 for mounting components, and the head 16 can be moved up and down (moved in the Z direction) and rotated (rotated in the R direction in FIG. 2). A frame member to be supported and a head drive mechanism using a servo motor as a drive source for moving the head 16 up and down and rotating are provided. With this configuration, the head unit 5 takes out the components from the component supply units 4 and 5 by the respective heads 16 and conveys the components onto the substrate P, and mounts the components on a predetermined position on the substrate P.

  The head 16 has a nozzle 20 (20A, 20B) at its tip. Specifically, the head 16 includes a head main body 17 (see FIG. 4) and a component suction nozzle 20 (20A, 20B) that is detachably attached to the tip thereof. The nozzle 20 can communicate with any of the negative pressure generator, the positive pressure generator, and the atmosphere via the passage 164 in the head body 17 and the switching valve. That is, the nozzle 20 sucks a component by receiving a negative pressure and then releases the suction state of the component by receiving a positive pressure.

  As shown in FIG. 2, in this example, among the six heads 16 of the head unit 5, the head 16 located at the end of the substrate carry-out side (X2 side) is a first nozzle 20A suitable for carrying connectors and the like. The other head 16 is an electronic component other than the connector or the like, that is, an electronic component that is housed in the tape feeder 4a or set on the tray 3a with the mounting surface on the substrate or the like being in the Z1 direction. Is provided with a second nozzle 20B suitable for the transfer of the above. The first nozzle 20 </ b> A is a component suction nozzle according to the present invention, and is configured so that the posture of the component can be changed around a horizontal axis after component suction, as will be described in detail later. On the other hand, the second nozzle 20B is a general nozzle that conveys the component as it is (without changing the posture of the component around the horizontal axis) while adsorbing the upper surface of the component.

  The image pickup unit 6 picks up an image of the component in order to recognize an image of the suction state of the component by the head 16 (nozzle 20). The imaging unit 6 includes a CCD camera for imaging a part and an illumination device having a plurality of LEDs. The imaging unit 6 is provided at a position between each component supply unit 3, 4 and the substrate transport mechanism 2.

  Next, a first embodiment of the first nozzle 20A will be described. In the following description of the first nozzle 20A, it is assumed that the first nozzle 20A is advanced on the basis of the XYZ rectangular coordinate axes shown in each drawing, with the state where the first nozzle 20A is mounted at the tip of the head body 17 as a reference. .

  FIG. 3 shows a single unit of the first nozzle 20A in a perspective view, and FIG. 4 shows the first nozzle 20A in a state of being mounted on the head body 17 in a sectional view. Reference numeral C1 in the drawing is a component mounted using the first nozzle 20A, and the component C1 is an insertion type connector as described later.

  The first nozzle 20 </ b> A holds the nozzle body 22, the component suction portion 23 supported by the nozzle body portion 22 so as to be rotatable about a horizontal axis, and the component suction portion 23 at a specific position in the rotation direction. A holding member 24 and a position switching mechanism for switching the position of the component suction portion 23 are included.

  The nozzle body 22 has an upper surface that is substantially circular in plan view, and includes a connecting portion 25 at the center of the upper surface. The first nozzle 20 </ b> A is detachably attached to the tip (lower end) of the head body 17 through the connecting portion 25.

  Specifically, as shown in FIG. 3, the connecting portion 25 includes a cylindrical portion 25 a extending upward from the upper surface of the nozzle main body portion 22 and an extending portion 25 b extending horizontally from the upper end thereof. On the other hand, as shown in FIG. 4, the head body 17 includes a hollow shaft member 17a supported by the frame member of the head unit 5, and a chuck mechanism 17b provided at the tip (lower end) of the shaft member 17a. . The chuck mechanism 17b includes a pair of locking pieces 171 that can be opened and closed, and a spring member 172 such as a leaf spring that urges the locking pieces 171 in the closing direction. Then, as shown in FIG. 4, the connecting portion 25 (extending portion 25b) of the first nozzle 20A is inserted between the pair of locking pieces 171 of the chuck mechanism 17b, and the connecting portion 25 is an elastic member of the spring member 172. The first nozzle 20 </ b> A is detachably attached to the tip of the head 16 by being pinched by the pair of locking pieces 171 by the generated force.

  The component suction portion 23 includes a component suction surface 23a at the tip thereof. The component suction portion 23 is rotatably supported by the nozzle body portion 22 via a support shaft 28 extending in a horizontal direction (in FIG. 4, a direction perpendicular to the paper surface / X direction). Specifically, a pair of leg portions 26 that are arranged in the X direction and extend downward in parallel to each other are provided at the lower portion of the nozzle body portion 22, and the base end portion of the component suction portion 23 is the pair of leg portions 26. Is inserted between. And the base end part of the component adsorption | suction part 23 is rotatably supported by the said support shaft 28 fixed over both the leg parts 26. As shown in FIG.

  With this configuration, the component suction unit 23 can change the posture of the component sucked by the suction surface 23a around the support shaft 28 (horizontal axis) with the rotation thereof. Specifically, as shown in FIG. 4, the component suction portion 23 has a first rotation position (corresponding to the first position of the present invention) in which the suction surface 23a is horizontal and downward, as shown in FIG. In addition, the suction surface 23a can be rotated over a second rotation position (corresponding to the second position of the present invention) in which the suction surface 23a is vertical. That is, the component suction unit 23 can rotate the posture of the component sucked on the suction surface 23 a by 90 ° around the support shaft 28.

  The nozzle main body 22 restricts the rotation (counterclockwise rotation in FIG. 4) in contact with the component suction portion 23 when the component suction portion 23 is disposed at the first rotation position. When the first restricting portion 22a and the component adsorbing portion 23 are disposed at the second rotation position, the second restricting portion 22a comes into contact with the component adsorbing portion 23 to restrict its rotation (clockwise rotation in FIG. 4). A restricting portion 22b is provided. By these first restricting portion 22a and second restricting portion 22b, the rotation range of the component suction portion 23 is restricted within a range of 90 ° from the first turning position to the second turning position.

  The position switching mechanism for switching the position of the component suction part 23 includes a cylindrical cylinder part 32 formed in the nozzle body part 22 and extending in the vertical direction, and a piston 33 disposed in the cylinder part 32 so as to be movable up and down. A spring 34 (corresponding to a biasing member of the present invention) disposed in the cylinder portion 32 and biasing the piston 33 downward, and extends in a direction perpendicular to the support shaft 28 (Y direction in FIG. 4). 33 and a link member 35 that connects the component suction portion 23 and a pin 37 that is fixed to the link member 35 and extends in the vertical direction.

  The link member 35 crosses the cylinder part 32 by being disposed in a slit 321 formed in the peripheral wall 32a of the cylinder part 32, and is fixed to the piston 33 at a substantially central part in the longitudinal direction. Thereby, the link member 35 can move in the vertical direction together with the piston 33 along the slit 321.

  One end of the link member 35 (the end on the Y2 direction side in FIG. 4) is rotatably connected to the component suction portion 23 through a long hole, and the other end (the Y1 direction side end). The pin 37 extending upward is press-fitted and fixed to the end). Thus, the vertical displacement of the pin 37 is converted into a rotational displacement around the support shaft 28 of the component suction portion 23 via the link member 35. That is, the position switching mechanism pushes down the piston 33 by the elastic force (biasing force) of the spring 34 and presses the component adsorbing portion 23 against the first restricting portion 22a in a state where no external force is applied to the pin 37. When the component suction portion 23 is arranged at the first rotation position by the above, and when an external force against the elastic force of the spring 34 acts on the pin 37 and the piston 33 is pushed up together with the link member 35, the component suction portion 23 is moved. The first rotation position is displaced to the second rotation position.

  An opening 38 is formed above the pin 37 in the nozzle body 22, and the pin 37 is located above the nozzle body 22 from the opening 38 when the link member 35 is lifted together with the piston 33. Protruding. The lower end portion of the pin 37 protrudes downward from the lower surface of the link member 35.

  In addition, a locking portion 351 formed so as to bulge outward (Y1 direction in FIG. 4) is provided at the end portion of the link member 35 on the pin 37 side. Then, when the piston 33 rises to a position where the component suction portion 23 comes into contact with the second restricting portion 22b, that is, a position where the component adsorbing portion 23 is disposed at the second rotation position, the holding member 24 engages with the locking portion 351, thereby The component suction portion 23 is held at the second rotation position. Specifically, as shown in FIG. 4, the holding member 24 is a leaf spring that extends in the vertical direction and includes a locking claw 241 at the tip (lower end), and its base end is fixed to the nozzle body 22. Thus, it is formed so as to be elastically bent and deformable in the horizontal direction (Y direction in FIG. 4). Then, as shown in FIG. 5, the holding member 24 engages with the locking portion 351 from the outside and locks the link member 35 with the nozzle main body portion 22, so that the component suction portion 23 is in the second rotation position. Retained. In this example, the holding member 24, the locking portion 351, and the like correspond to a holding mechanism that holds the component suction portion 23 in the second rotation position, and the spring 34 holds the component suction portion 23 in the first rotation position. It also functions as a holding mechanism.

  The lower end portion of the pin 37 is positioned below the lower end of the holding member 24 in a state where the link member 35 is pushed up. This is because when the pin 37 is pushed up together with the link member 35 by the posture changing stay 7 (see FIG. 10), the posture changing stay 7 does not interfere with the lower end of the holding member 24 and the holding member 24 This is because the link member 35 can be held. In this example, the lower end of the pin 37 protrudes downward from the link member 35, but the pin 37 may not protrude downward from the link member 35. In this case, in a state where the link member 35 is pushed up by the post-posture change stay 7, a part of the link member 35 is configured so that the post-posture change stay 7 and the holding member 24 do not interfere with each other. What is necessary is just to set it as the shape which protrudes below rather than a lower end.

  A reset member 162 for releasing the locking state of the link member 35 (locking portion 351) by the holding member 24 is provided at the lower end portion of the head unit 5, specifically, the lower end portion of the sleeve 161 that guides the head 16 in the vertical direction. Is provided. The reset member 162 is a pin extending downward, and is disposed on the circumference around the head body 17 and on the circumference where the pin 37 of the first nozzle 20A exists. That is, when the head 16 is raised to a predetermined reset height position in a state where the rotation position (position in the R direction) of the head 16 is adjusted so that the reset member 162 and the pin 37 face each other in the vertical direction, The reset member 162 is brought into contact with the pin 37 (see FIG. 5) protruding above the nozzle main body 22 and the pin 37 is pushed down, whereby the holding state of the link member 35 by the holding member 24 is released. After this release, the spring 34 pushes down the piston 33 by a resilient force to press the component suction portion 23 against the first restricting portion 22a, thereby placing and holding the component suction portion 23 at the first rotation position.

  In this example, the upper end portion of the pin 37 corresponds to the second external force input portion of the present invention, and the lower end portion of the pin 37 corresponds to the first external force input portion of the present invention. Further, the post-change posture stay 7 corresponds to a first external force applying member of the present invention, and the reset member 162 corresponds to a second external force applying member of the present invention.

  The first nozzle 20 </ b> A is provided with a negative pressure passage 40 for guiding the negative pressure for component suction supplied through the internal passage 164 of the head body 17 to the component suction portion 23. As shown in FIGS. 4 to 6, the negative pressure passage 40 opens to the upper end portion of the connecting portion 25 and extends in the vertical direction inside the nozzle body portion 22, and the first passage 40 a A pair of second passages 40b branched from the lower end portions and passed through the legs 26 and communicated with the third passages 40c formed in the support shaft 28, respectively, and the component suction portion 23 are formed. , A recess 231 provided in the suction surface 23a and a fourth passage 40d communicating the third passage 40c. The second passages 40b and the third passages 40c communicate with each other via two upper openings 28a formed in the support shaft 28. The third passage 40c and the fourth passage 40d are connected to the support shaft 28. Are communicated with each other through a lower opening 28b formed in the upper part.

  With this configuration, the negative pressure supplied to the first nozzle 20 </ b> A through the internal passage 164 of the head body 17 is guided to the suction surface 23 a through the nozzle body portion 22, the support shaft 28, and the component suction portion 23.

  The locking piece 171 that receives the elastic force of the spring member 172 presses the extended portion 25b against the tip of the shaft member 17a, so that the opening peripheral portion of the first passage 40a at the upper end portion of the extended portion 25b and the shaft The periphery of the opening of the internal passage 164 at the tip of the member 17a is in close contact with each other, and the internal passage 164 and the first passage 40a communicate with each other without leakage of negative pressure from the connection location.

  The component mounting apparatus M described above includes a control device 45 (shown in FIG. 1) based on a well-known microcomputer, and the operations of the head unit 5 and each head 16 are comprehensively controlled by the control device 45. Is done.

  Next, the component mounting operation control using the first nozzle 20A by the control device 45 will be described according to the flowchart of FIG. 7 with reference to FIGS.

  Before describing the mounting operation control, first, an example of a component C1 mounted using the first nozzle 20A will be described. A typical example of the component C1 is an insertion type connector as shown in FIG. This insertion type connector (referred to as component C1 for convenience) includes a rectangular parallelepiped housing Ca having a mating recess (not shown) of the mating connector housing, and a surface of the housing Ca opposite to the mating recess. And a plurality of leads Cb. This component C1 is mounted on the substrate P with the fitting concave portion facing upward by inserting a lead Cb into a through hole formed in the substrate P. Such a component C1 is difficult to be supplied in the same posture as when mounted on the substrate P. Therefore, the component C1 is supplied in a state in which it is placed on the trays 3a, 3b, more specifically, in a state in which it is placed on the trays 3a, 3b so that the fitting recesses are oriented sideways, and the first nozzle After being taken out from the trays 3a and 3b by 20A, the posture is changed by the first nozzle 20A.

  When the flowchart of FIG. 7 starts, the control device 45 moves the head unit 5 to the component supply unit 3 and sucks the component C1 by the first nozzle 20A (step S1). Specifically, the control device 45 moves the head unit 5 so that the first nozzle 20A is positioned above the component C1 placed on the trays 3a and 3b, and moves the head 16 to which the first nozzle 20A is mounted. The head 16 is raised after being lowered and sucking the component C1 by the first nozzle 20A. At this time, the first nozzle 20A is in a state where the component suction portion 23 is held at the first rotation position by the elastic force of the spring 34, and the control device 45 controls the switching valve to thereby absorb the component. Supply of negative pressure to the first nozzle 20A is started with the suction surface 23a of the portion 23 approaching the component C1 (housing Ca) or with the suction surface 23a contacting the component C1. Thereby, as shown in FIG. 8, the component C1 is adsorbed by the first nozzle 20A.

  Next, the control device 45 moves the head unit 5 to the vicinity of the substrate transport mechanism 2 and arranges the first nozzle 20A on the attitude changing stay 7 arranged along the conveyor 2a, and then is set in advance. The posture of the component C1 is changed by lowering the head 16 mounted with the first nozzle 20A to the posture change height position (step S3).

  More specifically, the posture changing stay 7 having, for example, a rectangular cross section is disposed along the conveyor 2a between the component supply unit 3 and the conveyor 2a (see FIG. 1). As shown in FIG. 9, the control device 45 is configured so that the lower end portion of the pin 37 is positioned on the posture changing stay 7 and the peripheral wall 32a of the cylinder portion 32 is separated from the posture changing stay 7 in the Y2 direction. One nozzle 20A is disposed, and the head 16 to which the first nozzle 20A is attached is lowered in this state. When the head 16 to which the first nozzle 20 </ b> A is mounted is lowered in this way, the posture change stay 7 relatively moves the link member 35 and the piston 33 against the elastic force of the spring 34 without interfering with the peripheral wall 32 a of the cylinder portion 32. The component suction portion 23 is rotated from the first rotation position to the second rotation position. And when the component adsorption | suction part 23 reaches the 2nd rotation position, ie, when the component adsorption | suction part 23 rotates to the position contact | abutted to the 2nd control part 22b, the holding member 24 will engage with the latching | locking part 351, The component suction portion 23 is held at the second rotation position. As a result, the component C1 rotates about the support shaft 28 by 90 °, and the posture of the component C1 is changed to a state where the lead Cb extends downward as shown in FIG.

  When the change of the posture of the component C1 is completed, the control device 45 mounts the first nozzle 20A until the lead Cb in a state of extending downward becomes a height that does not interfere with the mounted component on the imaging unit 6 or the substrate P. After the head 16 is raised, the head unit 5 is moved onto the imaging unit 6 and the imaging of the component C1 is performed by the imaging unit 6, thereby recognizing the component C1 based on the image data (step S5).

  Next, the control device 45 moves the head unit 5 above the substrate P, and mounts the component C1 attracted by the first nozzle 20A on the substrate P. Specifically, after the component C1 adsorbed by the first nozzle 20A is arranged in the target position information of the substrate P, the head 16 (first nozzle 20A) is lowered and the timing when the component C1 is placed on the substrate P. Then, the component C1 is mounted on the substrate P by cutting off the negative pressure supply (step S7). At this time, the control device 45 corrects the orientation of the component C1 in the R direction based on the recognition result in step S5 as necessary.

  When the mounting of the component C1 is completed, the control device 45 raises the head 16 to retract the first nozzle 20A from the substrate P, and the reset member 162 and the pin 37 face each other in the vertical direction as shown in FIG. The head 16 is raised to the reset height position while rotating the head 16 so as to reset the component suction portion 23 from the first rotation position to the second rotation position (steps S9 and S11). That is, the control device 45 brings the reset member 162 into contact with the pin 37 to release the locked state of the link member 35 by the holding member 24, thereby causing the component suction portion 23 to move to the first position by the elastic force of the spring 34. Move from the pivot position to the second pivot position.

  The above is one cycle of the mounting operation of the component C1 using the first nozzle 20A. When the component C1 is subsequently mounted, the control device 45 moves the process to step S1 after step S13. The processes of steps S1 to S13 are repeated.

  As described above, according to the component mounting apparatus M including the first nozzle 20A of the first embodiment, the posture of the component C1 can be changed around the horizontal axis (support shaft 28). The component C1, which is an insertion type connector placed horizontally on the board P, can be transported and mounted on the substrate P without difficulty. Moreover, according to the first nozzle 20A, as described above, the pin 37 (link member 35) is brought into contact with the posture changing stay 7 using the lowering operation of the head 16, or the raising operation of the head 16 is used. Then, by bringing the pin 37 into contact with the reset member 162, the position of the component suction portion 23 is displaced between the first rotation position and the second rotation position, so that the component C1 can be provided without providing a dedicated drive source. Can be changed around the horizontal axis.

  Therefore, according to the first nozzle 20A, it is possible to change the posture of the component C1 around the horizontal axis without enlarging the size of the head 16, and consequently the size and cost of the component mounting apparatus M. .

  Furthermore, according to the first nozzle 20A, the component suction portion 23 is pressed against the first restricting portion 22a by the elastic force (biasing force) of the spring 34, so that the component suction portion 23 is stabilized at the first rotational position. Can be retained. Therefore, at the time of component adsorption, the component C1 can be appropriately adsorbed while the component adsorption unit 23 is stably in contact with the component C1. Moreover, if the locking state of the link member 35 by the holding member 24 is released, the component adsorbing portion 23 is quickly reset from the second rotational position to the first movable position by the elastic force of the spring 34. After the component is mounted on P, the component suction portion 23 can be quickly reset to the first rotation position to shift to the next component suction operation. Therefore, the start of the next component suction operation is unlikely to be restricted due to the reset operation of the component suction unit 23, and thus the mounting operation of the component C1 can be advanced efficiently.

  Further, according to the component mounting apparatus M, the reset for resetting the component suction portion 23 at the second rotation position to the first rotation position (releasing the locking state of the link member 35 by the holding member 24). The member 162 is provided in the head unit 5, and after mounting the component C <b> 1, the component suction unit 23 is reset to the first movable position by bringing the pin 37 into contact with the reset member 162 while the head unit 5 is moving. can do. Therefore, the mounting operation of the component C1 can be efficiently advanced also in this respect.

  Next, a second embodiment of the first nozzle 20A according to the present invention will be described with reference to FIGS. The basic configuration of the first nozzle 20A according to the second embodiment (for convenience, the first nozzle 20A ′) is the same as that of the first nozzle 20A of the first embodiment. Next, differences between the first nozzle 20A ′ according to the second embodiment and the first nozzle 20A of the first embodiment will be described in detail.

  In the first nozzle 20A of the first embodiment, a cylinder portion 32, a piston 33, a link member 35, and a pin 37 are provided as a position switching mechanism for switching the position of the component suction portion 23, and the component suction portion 23 is rotated a predetermined time. A holding member 24 or the like was provided as a member for holding the moving position. In the first nozzle 20A ′ of the second embodiment, two sets of these configurations are provided.

  Specifically, as shown in FIGS. 12 and 13, the position switching mechanism of the first nozzle 20 </ b> A ′ of the second embodiment is centered on the support shaft 28 on one side (the Y <b> 1 side in the state shown in FIG. 12, That is, the first cylinder portion 32A and the first piston are arranged on the Y1 side in a state where the rotational position (position in the R direction) of the head 16 is adjusted so that the reset member 162 and a second pin 37B described later face each other in the vertical direction. 33A, a first link member 35A, and a first pin 37A, and on the other side (Y2 side in the state shown in FIG. 12), the second cylinder portion 32B, the second piston 33B, the second link member 35B, and the second A pin 37B is provided. Further, a first holding member 24A is provided on one side (Y1 side in the state shown in FIG. 12) of the support shaft 28, and a second holding member 24B is provided on the other side (Y2 side in the state shown in FIG. 12). .

  First cylinder part 32A, first piston 33A, first link member 35A, first holding member 24A and first pin 37A, second cylinder part 32B, second piston 33B, second link member 35B, second holding member The 24B and the second pin 37B are provided symmetrically about the support shaft 28 (symmetrical in FIG. 13).

  In the first nozzle 20A of the first embodiment, the pin 37 is fixed to the link member 35. However, in the first nozzle 20A ′ of the second embodiment, the first pin 37A is connected to the first piston 33A. By being fixed, it is accommodated in the first cylinder part 32A together with the first piston 33A. As a result, the first pin 37A can appear above and below the nozzle body portion 22 through the first opening 38A formed in the ceiling portion of the first cylinder portion 32A as the first piston 33A moves up and down. . On the other hand, the second pin 37B is housed in the second cylinder portion 32B together with the second piston 33B by being fixed to the second piston 33B. As a result, the second pin 37B can protrude upward and downward from the upper surface of the nozzle body portion 22 through the second opening 38B formed in the ceiling portion of the second cylinder portion 32B as the second piston 33B moves up and down. ing.

  As shown in FIGS. 13 and 14, when the component suction portion 23 is disposed at the first rotation position, the second pin 37B moves upward from the upper surface of the nozzle body portion 22 through the second opening 38B. On the other hand, the first link 37A protrudes upward from the upper surface of the nozzle body 22 through the first opening 38A when the component suction portion 23 is disposed at the second rotation position. The member 35 </ b> A and the second link member 35 </ b> B are connected to the component suction portion 23.

  In addition, when the component suction portion 23 is disposed at the first rotation position, the second holding member 24B engages with the locking portion 351 of the second link member 35B, while the component suction portion 23 performs the second rotation. The first holding member 24A is configured to engage with the locking portion 351 of the first link member 35A when disposed at the position.

  Then, the second link member 35B is locked by the second holding member 24B, so that the second pin 37B is in a state where the component suction portion 23 is held at the first rotation position (the state shown in FIG. 13). When pushed down by the reset member 162, the locking state of the second link member 35B by the second holding member 24B is released. When the reset member 162 is further pushed down against the elastic force of the spring 34 and the component suction portion 23 is displaced from the first rotation position to the second rotation position, the link member 35A is locked to the first link member 35A. The Thereby, the component adsorption | suction part 23 is hold | maintained in a 2nd rotation position (state shown in FIG. 14). In this state, when the first pin 37A is pushed down by the reset member 162, the locked state of the second link member 35B by the second holding member 24B is released. Even if the pressing by the reset member 162 is stopped in this state, the component adsorbing portion 23 is first rotated by the biasing force of the spring 34 accommodated in the first cylinder portion 32A so as to bias the first piston 33A downward. In this state, the second link member 35B is locked to the second holding member 24B. When the reset member 162 is further pushed down in the state where the second link member 35B is unlocked by the second holding member 24B, the component adsorbing portion 23 is moved by the push-down force and the biasing force of the spring 34. Displaced to one rotation position. In addition, the spring 34 quickly displaces the component adsorption | suction part 23 to a 1st rotation position in the state which the latching state of the 2nd link member 35B by the 2nd holding member 24B was cancelled | released. This prevents the component suction portion 23 from vibrating at an intermediate position between the first rotation position and the second rotation position.

  In this example, the second pin 37B corresponds to the second external force input portion of the present invention, and the first pin 37A corresponds to the first external force input portion of the present invention. The reset member 162 corresponds to the external force applying member of the present invention. The holding members 24A and 24B and the locking portions 351 of the link members 35A and 35B correspond to the holding mechanism of the present invention.

  When the first nozzle 20A ′ of the second embodiment is used, the operation control of the head unit 5 and each head 16 by the control device 45 basically uses the first nozzle 20A of the first embodiment. This is common to the case (the flowchart of FIG. 7), but differs from the operation control in the case where the first nozzle 20A of the first embodiment is used in the following points.

  That is, in step S1, when the component C1 is sucked by the component suction portion 23 held at the first rotation position, the control device 45 causes the second pin 37B and the reset member 162 to face each other in the vertical direction. Then, the head 16 is rotated to raise the head 16 to the reset height position (step S3). Thereby, the control apparatus 45 moves the components adsorption | suction part 23 from a 1st rotation position to a 2nd rotation position, and changes the attitude | position of the components C1. Specifically, the control device 45 rotates the head 16 so that the reset member 162 and the second pin 37B face each other in the vertical direction, and the reset member 162 is brought into contact with the second pin 37B, whereby the second holding member 24B. The second link member 35B is released from the locked state, and the component suction portion 23 is moved from the first rotation position to the second rotation position, and the first link member 35A is locked by the first holding member 24A. . The control device 45 performs such an operation of changing the posture of the component C1 while conveying the component C1 onto the imaging unit 6 after the component suction. Therefore, when the first nozzle 20A ′ of the second embodiment is used, the posture changing stay 7 is not used.

  In addition, when the mounting of the component C1 is completed in step S7, the control device 45 rotates the head 16 so that the first pin 37A and the reset member 162 face each other in the vertical direction, and reaches the reset height position. The head 16 is raised (steps S9 and S11). Thereby, the control apparatus 45 resets the components adsorption | suction part 23 from a 2nd rotation position to a 1st rotation position. Specifically, the control device 45 brings the reset member 162 into contact with the first pin 37A and releases the locking state of the link member 35A by the first holding member 24A, thereby moving the component suction portion 23 to the second rotation position. Then, the second link member 35B is locked by the second holding member 24B.

  According to the component mounting apparatus M including the first nozzle 20A ′ according to the second embodiment as described above, the first pin 37A and the second pin 37B are alternatively opposed to the reset member 162 by the rotation of the head 16. By raising the head 16 in this state, the position of the component suction portion 23 is switched (the first rotation position and the second rotation position) only with the reset member 162 (that is, without using the attitude changing stay 7). Switching).

  According to such a configuration, the posture of the component C1 can be changed during the movement while moving the head unit 5 directly from the component supply unit 3 onto the imaging unit 6 after the component is picked up. Further, after the component suction, the component suction unit 23 can be reset to the first movable position during the movement while moving the head unit 5 directly from the substrate P to the component supply unit 3. Therefore, as compared with the first nozzle 20A of the first embodiment, the component C1 can be mounted more efficiently because it is not necessary to go through the attitude changing stay 7. In addition, since the position of the component suction portion 23 is switched using the common reset member 162 provided in the head unit 5 as described above, the component mounting unit M including the first nozzle 20A ′ can be switched. For example, it is possible to efficiently mount the component C1 with a rational configuration.

  By the way, the above-described component mounting apparatus M is an example of a preferred embodiment of the component mounting apparatus according to the present invention, and the specific configuration of the component mounting apparatus M and the first nozzle 20A (component adsorption) applied thereto. The specific configuration of the nozzle for use can be appropriately changed without departing from the gist of the present invention. For example, the following configuration may be applied.

  (1) In the first nozzle 20A of the first embodiment shown in FIG. 4, the spring 34 may be omitted. That is, the piston 33, the link member 35, and the pin 37 are lowered by their own weights to bring the component suction part 23 into contact with the first restricting part 22a. It may be configured to be held in the moving position. According to this configuration, since the spring 34 is omitted, the structure of the first nozzle 20A can be simplified, reduced in weight, and reduced in cost.

  (2) In the first nozzle 20 </ b> A of the first embodiment shown in FIG. 4, the link member 35 is locked to the nozzle body 22 by the holding member 24 made of a leaf spring provided with the locking claw 241, thereby attracting the components. The part 23 is held at the second rotation position. However, the mechanism for holding the component suction portion 23 at the second rotation position is not limited to the configuration of the embodiment. As the holding mechanism of the present invention, various mechanisms such as a detent mechanism can be applied. The same applies to the first nozzle 20A ′ of the second embodiment shown in FIG. 12, and various mechanisms such as a detent mechanism are used as a mechanism for holding the component suction portion 23 at the first rotation position and the second rotation position. Can be applied.

  (3) In the component mounting apparatus M shown in FIG. 4, the reset member 162 is provided in the head unit 5 in order to reset the component suction portion 23 from the second rotation position to the first rotation position. The reset member 162 may be omitted and the attitude changing stay 7 may be used. That is, when resetting the component suction portion 23 from the second rotation position to the first rotation position, the pin 37 is positioned below the attitude converting stay 7 by the control of the head unit 5 and the like by the control device 45. After the first nozzle 20 </ b> A is arranged as described above, the head 16 may be raised and the pin 37 may be pushed down by the posture changing stay 7. According to this configuration, since the reset member 162 is not necessary for the head unit 5, the structure of the head unit 5 can be simplified and reduced in weight.

  Similarly, in the component mounting apparatus M shown in FIG. 12, the first pin 37 </ b> A and the second pin 37 </ b> B may be pushed down by the attitude changing stay 7.

  (4) In the description of the first nozzle 20A of the first embodiment shown in FIG. 4, the component C1 (insertion type connector or the like) placed sideways on the trays 3a and 3b is sucked and its posture is raised. The case where it mounted on the board | substrate P after changing was demonstrated. However, the first nozzle 20 </ b> A can also be applied to a case where the components placed on the trays 3 a and 3 b are sucked in a standing posture and are mounted on the substrate P after the posture is changed to the horizontal direction. This also applies to the first nozzle 20A ′ of the second embodiment shown in FIG.

  (5) In the description of the first nozzle 20A of the first embodiment shown in FIG. 4, the component suction portion 23 is configured to be rotatable by 90 ° around the support shaft 28, in other words, the posture of the component C1 is 90 °. However, the rotation angle of the component suction portion 23 is not limited to 90 °, and may be less than 90 ° or more than 90 °. This also applies to the first nozzle 20A ′ of the second embodiment shown in FIG.

  (6) In the first nozzle 20 </ b> A of the first embodiment shown in FIG. 4, the vertical displacement of the pin 37 is converted into the rotational displacement of the component suction portion 23 via the link member 35, so that the component suction A position switching mechanism is configured to change the rotation position of the portion 23. However, the specific configuration of the position switching mechanism is not limited to this. For example, a rack is provided on the pin 37 side, and a pinion that meshes with the rack is provided on the component suction portion 23 side, so that the vertical displacement of the pin 37 is converted into a displacement in the rotation direction of the component suction portion 23. May be. This also applies to the first nozzle 20A ′ of the second embodiment shown in FIG.

  (7) In the component mounting apparatus M shown in FIG. 1, in order to switch the attitude | position of the component adsorption | suction part 23, the stay 7 for attitude | position conversion is provided along the conveyor 2a. This posture changing stay 7 may be fixed to the side surface of the frame of the conveyor 2a or the like, or may be fixed to the base 1 via a frame member or the like. In addition to providing the dedicated posture changing stay 7 as described above, a configuration in which a specific portion of the conveyor 2a is also used as the posture changing stay may be employed. That is, a pin portion 37 (link member 35) may be brought into contact with the flange portion or the like using a flange portion or the like formed on the conveyor 2a. According to such a configuration, since the dedicated posture changing stay 7 is not required, the configuration of the component mounting apparatus M can be simplified and reduced in cost.

  (8) Further, the posture changing stay 7 is provided on the conveyor 2a or the base 1 as described above, for example, one end side of the unit support member 11 on which the head unit 5 is supported (one end in the X2 direction). Side) position may be supported via an arm member or the like. In this case, after the head unit 5 is moved to the one end side of the unit support member 11, the head 16 to which the first nozzle 20A is attached is lowered in this state, and the lower end portion of the pin 37 is used for posture conversion.

Further, the posture changing stay 7 may be provided on one end side (one end side in the Y direction) of the elevated frame to which the fixed rail 8 that supports the unit support member 11 is fixed. In this case, after the head unit 5 is moved together with the unit support member 11 to one end side of the elevated frame, the head 16 to which the first nozzle 20A is attached is lowered in this state, and the lower end portion of the pin 37 is positioned. What is necessary is just to make it contact | abut to the stay 7 for conversion.

  (9) In the above-described embodiment, the example in which the component suction nozzle according to the present invention (the component transport device provided with the component suction nozzle) is applied to the component mounting apparatus has been described. However, the component suction nozzle according to the present invention The component conveying device including the component suction nozzle can be applied to devices other than the component mounting device. For example, in a so-called component inspection device that picks up electronic components from a component supply tray (component supply unit) arranged at a predetermined position and transports the components onto a test device to perform various electrical inspections. Is also applicable.

  The present invention described above is summarized as follows.
