Description

  The present invention relates to an electronic component supply apparatus configured to vibrate a hollow long container in which components are stored and to send the components to a predetermined position.

  2. Description of the Related Art Conventionally, surface mounters that mount electronic components at predetermined positions on a printed circuit board are known. The surface mounter includes a component supply device that sequentially supplies electronic components to a predetermined component supply position.

  There are various types of component supply devices. As one type, a multi-stick feeder is known in which electronic components housed in a hollow long stick are sequentially moved to a component supply position by vibration. .

  The conventional multi-stick feeder is mainly generated by a vibration generator that is fixed to the container holder with a space between the container holder on which a plurality of sticks are placed, a vibration generator that is a source of vibration, and a container. It is comprised by a pair of diaphragm which receives the vibration which was made to vibrate a container holding part, and various support members, such as a vibration prevention board which supports the both ends of the vibration generator which protruded the outer side of the diaphragm.

  In such a multi-stick feeder, a plurality of sticks are placed on the container holding portion in an inclined posture such that the front end side is lower than the rear end side. Then, when the predetermined vibration generated by the vibration generating device is transmitted to the container holding unit and to the electronic component in the stick placed on the container holding unit, the electronic component in the stick moves in the longitudinal direction of the stick. (See Patent Document 1).

JP 2000-165091 A

  However, in the above conventional technique, when the distance between the pair of diaphragms is short, both ends of the stick easily swing with the vibration of the vibration generator, and the electronic component is moved to the component supply position as calculated. Is difficult. On the other hand, if the interval between the diaphragms is widened, there is a problem that the entire electronic component supply apparatus including the support member and the like disposed outside the diaphragm is enlarged.

  The present invention has been made in view of the above-described conventional problems, and an electronic component capable of suppressing the swing of the electronic component supply device accompanying the vibration of the vibration generator while avoiding an increase in the size of the electronic component supply device. The object is to provide a supply device.

  The component supply device of the present invention is an electronic component supply device that is mounted on a mounting machine body, vibrates a hollow long container in which components are stored, and sends the components to a predetermined position. A container holding unit that holds the container, a vibration generating device that is a source of vibration that vibrates the container holding unit, and a pair of vibrations that are spaced apart from each other and each end is fixed to the container holding unit A plate, a diaphragm supporting member that supports the other end of the diaphragm, a base member connected to the diaphragm supporting member via a vibration isolating member that prevents vibration transmission, and fixed to the base member And the base member, the vibration isolating member, the vibration plate supporting member, and the vibration generating device are disposed between the vibration plates in a side view. It is characterized by that.

  According to this invention, the base member, the vibration isolating member, the vibration plate supporting member, and the vibration generator are disposed between the vibration plates. In other words, the diaphragm is disposed on both outer sides of the base member, the vibration isolating member, the diaphragm supporting member, and the vibration generator. That is, the container holding portion is supported by the pair of diaphragms at a position farther away than before in the component supply direction. As a result, the vertical swing of both ends of the hollow long container extending in the component supply direction caused by the vibration of the vibration generator is suppressed, and the component is moved to a predetermined component supply position as calculated. Can be made. Furthermore, the space between the diaphragms obtained by separating the diaphragms is used as an arrangement space for the base member, the vibration isolating member, the diaphragm support member, and the vibration generator. As a result, it is possible to avoid the electronic component supply device from being enlarged so as to spread in the plane direction. Therefore, it is possible to suppress the swing of the electronic component supply device accompanying the vibration of the vibration generator while avoiding an increase in the size of the electronic component supply device.

  Moreover, it is preferable that the diaphragm supporting member and the base member are provided so as to overlap in a plan view.

  According to the present invention, by arranging the diaphragm supporting member and the base member so as to overlap in a plan view, the electronic component supply device can be prevented from being enlarged so as to spread in the planar direction. Therefore, the electronic component supply device can be made more compact in the horizontal direction.

  Moreover, it is preferable that the base member has an opening for arranging the vibration generating device.

  According to this invention, since the opening for arranging the vibration generator is formed in the base member, it is not necessary to shift the position of the vibration generator in the height direction with respect to the base member. Therefore, the electronic component supply device can be made compact in the vertical direction.

  The base member is disposed below the diaphragm supporting member, the vibration isolation member is disposed between the base member and the diaphragm supporting member, and the base member is disposed on the diaphragm. It is preferable that the support member is configured to be detachable.

  According to this invention, since the base member is configured to be detachable from the diaphragm support member, the base member and the diaphragm support member can be easily separated. Therefore, the workability at the time of maintenance such as replacement of the vibration isolating member provided between the base member and the diaphragm supporting member can be improved.

  The vibration generator includes a motor, a crank mechanism having an eccentric shaft that converts the rotational motion of the motor into a reciprocating motion in a component supply direction, and one end portion rotatably connected to the eccentric shaft. A connecting member rotatably connected to the container holding part, and the connecting member is disposed in a state of being inserted through an opening formed in the diaphragm supporting member. Is preferred.

  According to this invention, the vibration generating device has an extremely simple configuration of the motor, the crank mechanism, and the connecting member, and the connecting member is disposed so as to pass through the opening formed in the diaphragm supporting member, and the container Connected to the holding part. Therefore, the vibration generator is not easily restricted by its installation position. Further, since the connecting member is connected to the container holding part, the predetermined vibration generated by the vibration generator can be directly transmitted to the container holding part.

  ADVANTAGE OF THE INVENTION According to this invention, the oscillation of the electronic component supply apparatus accompanying the vibration of a vibration generator can be suppressed, avoiding enlargement of an electronic component supply apparatus.

  Each tape feeder 21 is wound around a reel with a reel and a space for accommodating the electronic component EC along the longitudinal direction formed at a predetermined interval, and the electronic component EC is accommodated in each space. And a feeding mechanism for intermittently feeding the tape. Each tape feeder 21 is assembled to a feeder base 17 (see FIG. 6) provided on the base 10.

  FIG. 2 is a side view for explaining the multi-stick feeder 3. FIG. 3 is a partially enlarged view of the multi-stick feeder 3. FIG. 4 is a rear view of a part of the multi-stick feeder 3.

  As shown in FIG. 2, the multi-stick feeder 3 includes a container holding unit 37 that holds a plurality of sticks (containers) 4, and a vibration generation device 39 that is a vibration generation source that vibrates the container holding unit 37. Four diaphragms 36 that are spaced apart and fixed at one end to the container holding portion 37, a diaphragm support member 35 that supports the other end of the diaphragm 36, and a diaphragm support member 35 The base member 33 is connected via a vibration isolation member 34, and the mounting member 31 is fixed to the base member 33 and is attached to the surface mounter main body.

  The container holding part 37 includes a tray-like bottom plate 37a and a side plate 37b that protrudes upward and extends backward.

  On the top surface of the bottom plate 37a, a plurality of sticks 4 having a long hollow shape (the cross section is rectangular) in which the electronic component EC is accommodated are placed with the longitudinal direction of the sticks parallel to the Y direction. Each stick 4 accommodates different types of electronic components EC. For this reason, the width of the stick 4 varies depending on the type of the electronic component EC accommodated therein. Each stick 4 is arranged on the container holding portion 37 in an inclined posture such that the rear side is supported at a predetermined height by the side plate 37b and the front end side is lower than the rear end side.

  In addition to this, on the front side end of the container holding part 37, on the upper part of the bottom plate 37a, there is a pressing mechanism for pressing the tip of each stick 4, and a passage for the electronic component EC supplied from the stick 4. A stopper for stopping the feeding path and the electronic component EC at a predetermined position on the feeding path (that is, a component supply position) is provided. Since these are not particularly limited in the present embodiment, description thereof is omitted here.

  FIG. 5 is a conceptual diagram for explaining the vibration generating device 39 of the multi-stick feeder.

  As shown in FIG. 5, the vibration generator 39 includes a motor 39a, a crank mechanism including an eccentric shaft 39b that converts the rotational motion of the motor 39a into a reciprocating motion in the supply direction of the electronic component EC, and an eccentric shaft. A connecting rod 39c having one end rotatably connected to 39b and the other end rotatably connected to the lower surface of the bottom plate 37a of the container holding portion 37, a motor 39a and a crank mechanism for supporting the diaphragm And a suspended plate 39d supported at a predetermined height so as to be suspended from the member 35.

  The motor 39a is provided so that its axis of rotation is parallel to the X direction. A first gear 39a1 is fixed to the rotation shaft of the motor 39a. The eccentric shaft 39b of the crank mechanism is provided with a second gear 39a2 at one end. The first gear 39a1 meshes with the second gear 39a2, and rotates the eccentric shaft 39b in conjunction with the rotational movement of the motor 39a. The center of the eccentric shaft 39b is set so as to deviate about 0.1 to 0.3 mm from the center of rotation of the second gear 39a2. The connecting rod 39c whose one end is rotatably connected to the eccentric shaft 39b receives the rotational motion of the eccentric shaft 39b, reciprocates in the Y direction, and transmits this motion to the container holding portion 37. . Thus, since the connecting rod 39 c is connected to the bottom plate 37 a of the container holding part 37, the predetermined vibration generated by the vibration generating device 39 can be directly transmitted to the container holding part 37. Moreover, desired vibration can be generated by appropriately adjusting the rotation speed of the motor 39a.

  The suspended plate 39d is fixed in a state where both side portions thereof are placed on the upper surface of the diaphragm support member 35 (a flat plate portion 35a described later).

  The vibration plate 36 is a front vibration plate 36a fixed to the front side (side closer to the conveyor 11) of the bottom plate 37a of the container holding portion 37, and the rear side fixed to the rear side (side far from the conveyor 11) of the bottom plate 37. It consists of 2 pairs of board | plate materials which make the diaphragm 36b 1 set. Specifically, the upper end portions of the four diaphragms 36 are respectively fixed to the container holding portion 37 via mounting brackets. The front diaphragm 36a and the rear diaphragm 36b are fixed in parallel with each other at a predetermined interval in a state where the front diaphragm 36a and the bottom plate 37a of the container holding portion 37 are inclined at a predetermined angle in a side view. Has been.

  When the vibration of the vibration generating device 39 is transmitted through the container holding part 37, the vibration plate 36 vibrates so as to amplify the vibration of the container holding part 37. In this way, receiving the vibrations of the vibration generating device 39 and the diaphragm 36, the container holding unit 37 vibrates so as to move the electronic component EC housed in the stick 4 to the component supply position at a predetermined speed.

  The vibration plate supporting member 35 extends in the Y direction, and is provided below the flat plate portion 35a provided in a posture substantially parallel to the bottom plate 37a of the container holding portion 37, and the front end of the flat plate portion 35a (the end closer to the conveyor 11). Is provided so as to protrude downward, at the front support portion 35b that is substantially L-shaped in a side view, and at the rear end of the flat plate portion 35a (the end on the side far from the conveyor 11), And a rear support portion 35c having a substantially L shape in a side view. The lower end part of the front diaphragm 36a is fixed to the front support part 35b, and the lower end part of the rear diaphragm 36b is fixed to the rear support part 35c. Thus, by fixing each diaphragm 36a, 36b with the front support part 35b and the rear support part 35c which protruded downward from the flat plate part 35a, the fixed position between the upper end part and the fixed position of the lower end part is predetermined. Only the distance is secured. Further, an opening 35a1 is formed at a predetermined position in the flat plate portion 35a (see FIGS. 3 and 4). The above-described suspension plate 39d is provided so as to straddle the opening 35a1, and the connecting rod 39c, the crank mechanism, and the motor 39a are arranged in a state of being inserted through the opening 35a1. Therefore, even if the diaphragm supporting member 35 is provided, the vibration generating device 39 is disposed in the opening 35a1 formed in the diaphragm supporting member 35, and thus the installation position is not easily restricted.

  The vibration isolating member 34 is a member for preventing vibration generated by the vibration generating device 39 from being transmitted to the base member 33 and further to the surface mounting machine main body via the mounting member 31. Therefore, the vibration isolation member 34 is provided so as to separate the diaphragm support member 35 and the base member 33. The anti-vibration member 34 includes a block-like anti-vibration rubber and a pair of attachment members that sandwich the anti-vibration rubber from both upper and lower ends. In the present embodiment, the vibration isolation members 34 are arranged one by one at the four corners of the lower surface of the diaphragm support member 35. As described above, the vibration plate support member 35 and the base member 33 are connected via the elastic member, so that the vibration energy is absorbed before being transmitted to the base member 33.

  The base member 33 is a plate-like member disposed substantially horizontally below the diaphragm support member 35 so as to overlap the diaphragm support member 35 in plan view. The base member 33 is detachably attached to the vibration isolation member 34 and is fixed to the mounting member 31 with screws or the like. In other words, the base member 33 is also a member that supports the diaphragm support member 35 supported by the four vibration isolation members 34.

  The base member 33 has an opening 33a having a predetermined size at a predetermined position. The vibration generator 39 is provided in the opening 33a. Therefore, it is possible to avoid interference between the base member 33 and the vibration generating device 39 while arranging the vibration generating device 39 and the base member 33 at substantially the same height. That is, since it is not necessary to shift the position of the vibration generating device 39 in the height direction with respect to the base member 33, the multi-stick feeder 3 can be made compact in the vertical direction.

  The mounting member 31 is a member extending in the X direction for mounting the multi-stick feeder 3 to the mounting machine body. The mounting member 31 protrudes forward in the Y direction and is inserted into a predetermined position of the feeder base 17 (see FIG. 6) to position the mounting member 31 and a predetermined portion of the feeder base 17. And a clamp 31b for attaching the mounting member 31 to the feeder base 17 at a predetermined position. The mounting member 31 supports the lower surface of the base member 33, and a control unit 32 for controlling the driving of the vibration generating device 39 is fixed to the mounting member 31 so as to protrude downward. The control unit 32 stops driving the vibration generator 39 after the electronic component EC has moved to the component supply position. Specifically, the vibration of the vibration generator 39 is stopped at a timing when a predetermined time (time required for the electronic component EC to move to the component supply position) set in the timer in the control unit 32 has elapsed.

  As described above, in the present embodiment, various support members (base member 33, vibration isolation member 34, diaphragm support member 35) and the front diaphragm 36a and the rear diaphragm 36b, as viewed from the side, A vibration generator 39 is provided. Thereby, the support position of the container holding part 37 (that is, the fixed position of the front diaphragm 36a and the rear diaphragm 36b) is separated in the Y direction, the support state of the container holding part 37 is stabilized, and the container holding part 37 Suppresses swinging. Further, the various support members and the vibration generator 39 are housed between the front diaphragm 36a and the rear diaphragm 36b so as not to spread in the horizontal direction. Thereby, the multi-stick feeder 3 realizes a compact configuration as a whole.

  FIG. 6 is a conceptual diagram for explaining a state in which the multi-stick feeder 3 is mounted on the surface mounter.

  In the surface mounting machine equipped with the multi-stick feeder 3, the input operation of the suction position when the electronic component EC supplied from each stick 4 to the component supply position is sucked by the suction head 14a of the head unit 14 is semi-automatic. Done.

  The suction position input operation is an operation for obtaining target coordinates for moving the lower end of the suction head 14a directly above the electronic component EC.

  For example, in the case of the tape feeder 21, since the tape feeder 21 is positioned and attached to a predetermined position of the feeder base 17, the center coordinates of the electronic component EC supplied to the component supply position are determined at the design stage. It almost coincides with the suction point made. Therefore, such an operation for inputting the suction position is not necessary. However, in the case of the multi-stick feeder 3, a plurality of sticks 4 having different widths that are arbitrarily arranged are placed on the container holding unit 37, and the electronic component EC supplied from each stick 4 is placed on the container holding unit 37. Are fed at intervals corresponding to the width of the stick. For this reason, the center coordinates of the electronic component EC supplied from the stick 4 are different from the suction points determined in the design stage. Therefore, as an initial setting, it is necessary to store the target coordinates for moving the lower end of the suction head 14 directly above the electronic component EC in the controller 6 provided in the surface mounter.

Specifically, the operator operates the input means 7 such as the mouse 71 and the keyboard 72 to move the head unit 14. Then, the electronic camera EC is scanned by the scan camera 14c provided in the head unit 14, the image is displayed on the monitor 5, the image processing is performed, and the central coordinates (X _A , Y _A ) of the electronic component EC are obtained by the surface mounter. Store in the controller. Next, an operation of storing the center coordinates (X _B , Y _B ) for the electronic component EC adjacent in the X direction on the transmission path is performed. Thus, the central coordinates (X _A , Y _A ) to (X _D , Y _D ) of all the electronic components EC supplied to the component supply position from the stick 4 placed on the multi-stick feeder 3 are stored in the controller 6. .

  Furthermore, in the present embodiment, even if the mounting position of the multi-stick feeder 3 on the feeder base 17 is changed, if the type and arrangement state of the sticks 4 are not changed, the initial setting is already stored. By using the set target coordinates, it is possible to respond without performing initial setting again.

  Specifically, the feeder base 17 is provided with positions 1 to X to N for positioning when the tape feeder 21 is mounted. The multi-stick feeder 3 is positioned by mounting a positioning pin 31a provided on the mounting member 31 at any one of positions 1 to X to N. For example, it is possible to cope with the case where the multi-stick feeder 3 initially attached to the position 5 is to be attached to the position 6 for some reason.

Specifically, at the time of initial setting, in addition to the center coordinates (X _A , Y _A ) to (X _D , Y _D ) of each electronic component EC supplied to the component supply position of the multi-stick feeder 3, The relative coordinates of the center position of each electronic component EC obtained with the multi-stick feeder 3 attached to the position 5 is calculated using the suction position unique to the position 5 when the tape feeder 21 is attached as the origin, and the controller 6 Remember me. When the multi-stick feeder 3 is attached to the position 6, the center coordinates (X _A , Y _A ) of the electronic component EC are obtained from the coordinates of the suction position unique to the position 6 and the information of the relative coordinates obtained at the initial setting. ˜ (X _D , Y _D ) are calculated and stored in the controller 6.

  As described above, by storing the relative coordinates with the suction position unique to each position as the origin at the time of initial setting in the controller 6, it is possible to flexibly cope with a change in the mounting position of the multi-stick feeder 3. Become. Accordingly, the installation of the multi-stick feeder 3 can be completed quickly, and the mounting position of the multi-stick feeder 3 is not limited, so that the burden on the operator can be reduced.

  According to the above embodiment, the base member 33, the vibration isolating member 34, the vibration plate supporting member 35, and the vibration generating device 39 are disposed between the pair of vibration plates 36a and 36b in a side view. In other words, the diaphragms 36 a and 36 b are disposed on both outer sides of the base member 33, the vibration isolation member 34, the diaphragm support member 35, and the vibration generator 39. That is, the container holding part 36 is supported by the pair of diaphragms 36a and 36b at a position farther away than before in the component supply direction, that is, the Y direction. This suppresses the vertical swing of both ends of the hollow elongated stick 4 extending in the supply direction of the electronic component EC, which is caused by the vibration of the vibration generating device 39, and determines the electronic component EC as calculated. It can be moved to the parts supply position. Furthermore, the space between the diaphragms 36a and 36b obtained by separating the diaphragms 36a and 36b is arranged in the arrangement of the base member 33, the vibration isolator 34, the diaphragm support member 35, and the vibration generator 39. It is used as a space. As a result, the multi-stick feeder 3 can be prevented from being enlarged so as to spread in the plane direction. Therefore, swinging of the multi-stick feeder 3 accompanying vibration of the vibration generator 39 can be suppressed while avoiding an increase in size of the multi-stick feeder 3.
