Description

A component holding head for surface mounter, method for determining position of sensor in the component holding head, and jig for determining position of sensor in the component holding head}

The present invention provides a component holding head having a component holding mechanism for holding a component in a surface mounter for mounting a component (electronic component) such as an IC chip on a substrate, a sensor positioning method and a sensor position in the component holding head. A component holding head having a crystal jig.

In general, the surface mounter moves the component holding head above the component supplying part, performs a downward raising operation to the nozzle serving as the component holding mechanism provided in the component holding head, vacuum-adsorbs the component to the lower end of the nozzle, and After the next component holding head is moved above the substrate, the component is mounted at a predetermined coordinate position of the substrate by causing the nozzle to move up and down again from above the substrate.

As described above, when picking up a component by raising and lowering the nozzle, if the downward stroke of the nozzle is too large, the lower end portion of the nozzle strongly presses on the upper surface of the component to increase the risk of component breakdown, and if the downward stroke of the nozzle is too small, the nozzle It can't land on the top of the part, preventing it from picking up the part.

The same applies to the case where the component is mounted on the substrate. In other words, if the downward stroke of the nozzle is too large, the component adsorbed on the lower end of the nozzle strongly presses the substrate, increasing the risk of the component being broken. If the downward stroke of the nozzle is too small, the component cannot land on the upper surface of the substrate, thereby mounting the component. You won't be able to. Therefore, the down stroke of the nozzle must be properly controlled.

As a method for appropriately controlling the down stroke of the nozzle, a method using a detection means (a sensor for detecting the nozzle) for detecting the landing of the nozzle is disclosed in Japanese Patent No. 3553044.

However, in the method of Japanese Patent No. 3553044, it is necessary to provide a sensor for each nozzle. That is, in the component holding head provided with a plurality of nozzles, it is necessary to install a plurality of sensors in correspondence with each nozzle, resulting in problems in the installation space and also causing a cost increase.

In contrast, in the Japanese Patent Application No. 2013-212220, the applicant of the present application provides a spindle on which a nozzle is mounted and a lifting member (pressure part) for lifting it up as a separate member and a component holding head having a sensor installed on the lifting member side. Suggested. According to this component holding head, it is unnecessary to provide several sensors corresponding to each nozzle.

However, with the structure provided with the sensor in the elevating member, when the elevating member is assembled to the main frame of the component holding head, in particular, when the adjustment to suppress the friction of the elevating shaft is performed, the position shift may occur in the elevating member. If the position shift occurs in the elevating member, the position of the sensor is also shifted in conjunction with this, so that the nozzle (change in position of the nozzle) cannot be accurately detected by the sensor.

According to one aspect of the present invention, the main problem is to position the sensor at a desired position by enabling the correction of the positional shift of the sensor that detects the component holding mechanism (nozzle) in the component holding head of the surface mounter.

According to an aspect of the present invention, the spindle; and an elevating member for elevating the spindle in the Z direction along its axial direction; and a component holding mechanism installed at the lower end of the spindle; And a component holding head of a surface mounter including a sensor connected to the elevating member with a position adjusting mechanism interposed therebetween.

Here, the sensor is an optical fiber sensor, the optical fiber sensor may include an optical axis direction adjusting means for adjusting the optical axis direction.

Here, the position adjustment mechanism may include an XY direction position adjusting member for adjusting the position of the sensor in the XY direction perpendicular to the Z direction.

Here, the position adjusting mechanism may include a Z direction adjusting member for adjusting the position of the sensor in the Z direction.

Here, the position adjusting mechanism includes: an XY direction position adjusting member for adjusting the position of the sensor in the XY direction perpendicular to the Z direction; and a Z direction position adjusting member for adjusting the position of the sensor in the Z direction. It may include.

Here, an arm member may be connected to the lifting member with the XY direction positioning member interposed therebetween, and the sensor may be connected with the arm member with the Z direction positioning member interposed therebetween.

According to another aspect of the present invention, a component of a surface mounter, which is applied to a component holding head of the surface mounter and determines the XY direction position of the arm member by an arm positioning jig provided on the main frame of the component holding head. A sensor positioning method at a holding head is provided.

According to still another aspect of the present invention, a part is applied to a component holding head of the surface mounter, and the sensor is an optical fiber sensor, and a jig positioning unit for positioning with respect to the main frame of the component holding head; and the spindle It provides a sensor positioning jig comprising a; jig position fixing unit for fixing the position of; and a target position indicating the target position of the optical axis of the optical fiber sensor.

According to another aspect of the present invention, applied to the sensor positioning jig, positioning the jig positioning portion relative to the main frame, and after fixing the position of the spindle in the jig position fixing portion of the optical fiber sensor It provides a sensor positioning method for adjusting the position of the optical fiber sensor by the position adjustment mechanism so that the optical axis is matched to the target position.

According to one aspect of the present invention, since the sensor detecting the component holding mechanism (nozzle) is connected to the lifting member via the position adjusting mechanism, even if a position shift occurs in the lifting member, the position of the sensor is determined by the position adjusting mechanism. Misalignment can be corrected and this has the effect of positioning the sensor at a desired position.

In addition, the use of the arm positioning jig or the sensor positioning jig according to one aspect of the present invention has the effect that the sensor positioning can be performed easily and accurately, and that the positioning can be performed outside the actual device.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, in this specification and drawing, duplication description is abbreviate | omitted by using the same code | symbol about the component which has substantially the same structure.

1 is a perspective view showing the overall configuration of a component holding head according to an embodiment of the present invention.

As shown in FIG. 1, the component holding head 10 is a rotary head type component holding head, and the rotary head 40 is rotatable in the R direction around the vertical axis on the main frame 20 constituting the head body. It is installed. In this rotary head 40, a plurality of spindles 41 are arranged at equal intervals along the circumferential direction, and a nozzle 42 is mounted as a part holding mechanism for sucking and holding parts at the lower ends of the spindles 41. .

The rotary head 40 can rotate in the R direction by driving the R servo motor 21 provided in the main frame 20. Moreover, each spindle 41 can be rotated in the T direction around the axis line of each spindle 41 by the drive of the T servo motor 22 provided in the main frame 20.

Moreover, the Z servo motor 23 for arranging the spindle 41a (refer FIG. 3) in a specific position to raise and lower in the Z direction which is an axial direction is arrange | positioned in the main frame 20. As shown in FIG. The mechanism for rotating the rotary head 40 in the R direction by driving the R servo motor 21, and the mechanism for rotating each spindle 41 in the T direction by driving the T servo motor 22 are well known. Its description will be omitted here. The mechanism for elevating the spindle 41a by the drive of the Z servo motor 23 will be described below.

FIG. 2 is a view showing a mechanism for elevating the spindle 41a in the Z direction in the component holding head 10 of FIG. 1, (a) is a front view, (b) a left side view, (c), ( d) is a perspective view of a main part.

The motor shaft of the Z servo motor 23 is connected to the screw shaft 24 of the ball screw mechanism, and the nut of the ball screw mechanism is attached to the screw shaft 24. In addition, the lifting member 25 is fastened to the nut.

Moreover, the upper spline shaft 26 is attached to the elevating member 25 for rotation stop and elevating guide. And the press part 25a is integrally connected with this lifting member 25. As shown in FIG. Therefore, the pressurizing part 25a moves in the Z direction with the lifting member 25 by the drive of the Z servo motor 23.

Only one lifting member 25 and one pressing portion 25a are provided on the main frame 20 side. When lowering the spindle 41, the spindle 41 is moved relative to the pressing portion 25a, thereby selecting the lowering spindle 41 (the spindle 41a at the specific position) and pressing the pressing portion 25a. By lowering the spindle 41a and the nozzle 42 mounted on the lower end thereof are lowered.

 In this embodiment, as shown in FIG. 3, the rotary head 40 is rotated in the R direction to move the spindle 41 relative to the pressing portion 25a relative to the pressing portion 25a so that the spindle 41 to be lowered is placed under the pressing portion 25a. Position it. Then, the pressing portion 25a is lowered to lower the spindle 41a directly below the pressing portion 25a. However, the configuration for selecting and lowering the spindle 41a at a specific position is not limited to the configuration described above. For example, the spindle 41a may be directly selected by moving the pressurizing portion 25a while lowering the spindle 41.

As shown in FIG. 2, a part of the arm member 28 is connected to the lifting member 25 to which the pressing portion 25a is connected, with the adapter member 27 interposed therebetween, and the end of the arm member 28 is connected. The optical fiber sensor 30 is connected and provided as a sensor which detects a nozzle with the sensor holder member 29 on the side.

Moreover, the lower spline shaft 31 is attached to the end side of the arm member 28 as a guide member to guide the lifting and lowering of the arm member 28 according to the lifting and lowering of the lifting member 25. The lower spline shaft 31 is fixed to the main frame 20 with the fixing member 32 therebetween.

The said adapter member 27 is an XY direction position adjustment member for adjusting the position of the XY direction of the optical fiber sensor 30 here. In other words, the adapter member 27 is connected to the lifting member 25 in a XY direction in a horizontal plane perpendicular to the Z direction. Thereby, the position in the XY direction of the arm member 28 integral with the adapter member 27 can be adjusted, and as a result, the position in the XY direction of the optical fiber sensor 30 connected to the arm member 28 can be adjusted.

Moreover, the sensor holder member 29 is a position adjustment mechanism, and is a Z direction positioning member for adjusting the position of the optical fiber sensor 30 in the Z direction. That is, the sensor holder member 29 is connected to the arm member 28 so that the position can be adjusted in the Z direction. As a result, the position in the Z direction of the optical fiber sensor 30 that is integrally connected to (maintained) the sensor holder member 29 is adjusted.

In this way, the optical fiber sensor 30 is connected to the elevating member 25 with the adapter member 27, the arm member 28 and the sensor holder member 29 interposed therebetween, and the adapter member 27 and the sensor holder member ( After the position adjustment by 29 is made, it is integrated with the elevating member 25 and the press part 25a. Therefore, when the pressurizing part 25a moves to Z direction by the drive of the Z servo motor 23, the optical fiber sensor 30 will move to Z direction in conjunction with this. That is, the optical fiber sensor 30 moves in the Z direction in synchronism with the movement in the Z direction of the spindle 41a by the lifting and lowering of the pressurizing portion 25a. In addition, the spindle 41 is always elastically pressed toward the upper initial position by the elastic body 41b (refer FIG. 1) which consists of two coil springs.

The optical fiber sensor 30 is a structure in which a light emitting portion and a light receiving portion are sandwiched together with an optical fiber or a lens, and the structure itself is well known. 4 is a perspective view showing the main part of the optical fiber sensor 30 used in the present embodiment, including its mounting state.

As described above, the optical fiber sensor 30 is connected to the arm member 28 with the sensor holder member 29 interposed therebetween. The optical fiber sensor 30 of this embodiment has an eccentric collar 30a as an optical axis direction adjusting means for adjusting the optical axis direction. That is, the eccentric collar 30a is attached to the lens 30b of the optical fiber sensor 30, and the optical axis direction of the optical fiber sensor 30 is adjusted by rotating this eccentric collar 30a with respect to the lens 30b.

Next, the sensor function of the optical fiber sensor 30 will be described.

In this embodiment, the optical fiber sensor 30 is arrange | positioned obliquely above the nozzle 42 (nozzle 42 in the said specific position) attached to the lower end of the spindle 41 as shown in FIG. And the light emitting part of the optical fiber sensor 30 irradiates light P obliquely downward toward the reflecting surface 42a of the outer periphery upper surface of the nozzle 42 enlarged in FIG. The irradiated light P is reflected by the reflecting surface 42a, and the reflected reflected light is received by the light receiving portion of the optical fiber sensor 30.

Here, the nozzle 42 is attached to the lower end of the spindle 41 via the coil spring 43 (elastic body) as shown in FIG. Therefore, when the spindle 41a at the specific position is lowered and the nozzle 42 is landed, the coil spring 43 is compressed to change the relative position of the nozzle 42 with respect to the spindle 41a in the vertical direction. Specifically, the nozzle 42 moves relatively toward the lower end side of the spindle 41a.

On the other hand, the light P irradiated from the light emitting portion of the optical fiber sensor 30 is reflected by the lens 30b shown in FIG. 4 to the reflecting surface 42a when the nozzle 42 is not in the initial state. Focus is on. Therefore, when the nozzle 42 is landed and the position of the nozzle 42 with respect to the spindle 41a in the up and down direction is changed, the amount of reflected light reflected by the reflecting surface 42a is reduced, so that the light receiving portion of the optical fiber sensor 30 is reduced. The amount of light received by the light is reduced (see FIG. 6). In this embodiment, the decrease in the amount of received light is detected by a sensor unit (not shown) of the optical fiber sensor 30. Then, the sensor unit determines that the nozzle 42 has landed when the received amount of light decreases by a predetermined amount, for example, when it is equal to or less than the threshold A shown in FIG. 6, and generates a 'landing detection signal'.

Here, the expression that the nozzle 42 has been 'landed' means that the force acted from below the nozzle 42, in which case the nozzle 42 moves downward in the pick-up process of the part, and then the nozzle 42 The case where the lower end part lands on the upper surface of a component, and the component adsorbed-held by the lower end part of the nozzle 42 in the component mounting process land on the upper surface of a board | substrate.

In the above configuration, the surface mounter having the component holding head 10 picks up and holds the component from the component supply by the nozzle 42 mounted at the lower end of the spindle 41, transfers it onto the printed circuit board, and transfers the component onto the printed circuit board. Mount on location.

At the time of picking up the parts and mounting the parts, as described with reference to FIG. 3, the pressing section 25a presses the upper surface of the spindle 41a positioned directly below the pressing section 25a, and the spindle 41a moves in the Z direction. Descend to.

Then, when the nozzle 42 at the end of the spindle 41a lands, the coil spring 43 is compressed as described above, and the vertical position of the nozzle 42 with respect to the spindle 41a is changed to change the optical fiber sensor 30. The amount of light received by the light receiving portion of the light decreases. Then, the sensor unit of the optical fiber sensor 30 generates a landing detection signal. This landing detection signal is transmitted to the control part of a surface mounter. When this control part receives a landing detection signal, the Z servo motor 23 which lowers the press part 25a is stopped. As a result, the lowering stroke of the nozzle 42 is appropriately controlled so that the nozzle 42 accurately lands.

Next, the positioning method of the optical fiber sensor 30 will be described. An adapter member 27 and a sensor holder member 29 are used as a mechanism (position adjusting mechanism) for adjusting the position of the sensor, which will be described below.

First, the elevating member 25 shown in FIG. 2 is assembled to the main frame 20 on the basis of the upper spline shaft 26 and then fastened with the nut of the aforementioned ball screw mechanism. Next, the arm member 28 is connected to the lifting member 25 with the adapter member 27 interposed therebetween.

The adapter member 27 is an XY direction positioning member as a positioning mechanism. The arm member 28 and the adapter member 27 are integral, and the adapter member 27 can be adjusted in the XY direction with respect to the elevating member 25, so that the position of the arm member 28 in the XY direction can be adjusted. Thus, adjustment of the XY direction position of the optical fiber sensor 30 can also be performed.

Specifically, as shown in FIG. 7, the XY direction position of the arm member 28 is adjusted using the arm positioning jig 50. In FIG. 7, (a) is a figure which shows the back surface of the component holding head 10, (b) is a figure which shows the left side surface.

More specifically, a part of the arm member 28 has a step, and the step part becomes an attachment portion (attachment surface) 28a to which the sensor holder member 29 is attached, so that the The XY direction position of the arm member 28 is adjusted using the arm positioning jig 50 so that an XY direction position may be a desired position.

The arm positioning jig 50 has a fastening part 51 whose one end is fastened to the main frame 20 and is installed, and an arm positioning part (positioning surface) 52 whose other end collides with the attachment part 28a. Has

When the attachment portion 28a strikes the arm positioning portion 52, the XY direction position of the attachment portion 28a is positioned at a desired position. Specifically, the attachment part 28a and the arm positioning part 52 which are shown in FIG.7 (a) collide, and the X direction position of the attachment part 28a is positioned, and it is shown in FIG.7 (b). The attachment part 28a and the arm positioning part 52 collide with each other, and the Y-direction position of the attachment part 28a is positioned. That is, the arm positioning jig 50 has the upper spline shaft 26, the ball screw mechanism, and the elevating member 25 described above because the one end fastening portion 51 is fastened and positioned to the main frame 20. Irrespective of the position error of), the XY direction position of the attachment portion 28a of the arm member 28 can be positioned to a desired position. Then, at this position, a part of the arm member 28 is fixed to the lifting member 25 with the adapter member 27 interposed therebetween.

On the other hand, the lower spline shaft 31 is mounted on the end side of the arm member 28, and the lower spline shaft 31 is fixed to the main frame 20 with the fixing member 32 interposed therebetween. At this time, the fixing member 32 is fixed to the main frame 20 along the position of the lower spline shaft 31 attached to the arm member 28 whose position in the XY direction is adjusted.

As described above, the arm member 28 is connected to the elevating member 25 in a XY direction with the adapter member 27 interposed therebetween, whereby the upper spline shaft 26 and the ball screw mechanism are aligned and lowered. The alignment of the spline shaft 31 and the arm member 28 does not interfere with each other. Therefore, not only the smooth lifting operation but also the accurate position of the arm member 28, that is, the accurate XY position of the optical fiber sensor 30 can be realized.

Next, the mode of determining the Z direction position of the optical fiber sensor 30 will be described.

Specifically, the sensor holder member 29 which holds the optical fiber sensor 30 as shown in FIG. 8 with respect to the attachment part 28a of the arm member 28 in which the positioning in the XY direction was performed by the above-mentioned method. To determine the Z-direction position of the optical fiber sensor 30. In FIG. 8, (a) is the figure which showed the back surface of the component holding head 10, (b) is the figure which shows the left side surface.

As described above, the optical fiber sensor 30 is positioned with respect to all directions of XYZ. In this embodiment, the optical axis (focal position) of the final optical fiber sensor 30 is adjusted using the sensor positioning jig 60. .

FIG. 9 is a perspective view showing the sensor positioning jig 60, and FIG. 10 is a view showing the use state thereof. In addition, in FIG. 10, (a) is a figure which shows the left side surface of the component holding head 10, (b) shows the figure which shows the bottom surface.

The sensor positioning jig 60 has a jig positioning part 61, a jig position fixing part 62, and a target position part 63.

When using the sensor positioning jig 60, first, the jig positioning unit 61 hits the reference plate 20b attached to the head mounting plate 20a constituting the main frame 20 so that the sensor positioning jig ( Position 60 relative to the main frame 20. Then, the jig position fixing part 62 is fitted to the lower end of the spindle 41 to fix the position in the R direction of the spindle 41 (rotary head 40). Thereby, the sensor positioning jig 60 and the spindle 41 (rotary head 40) are positioned with respect to the XYZ direction, and in this positioned state, the target position portion 63 moves the optical axis (focus of the optical fiber sensor 30). Position).

The optical axis of the optical fiber sensor 30 is finally adjusted so that the optical axis of the optical fiber sensor 30 is matched with this target position portion 63 to match. Although the optical axis adjustment of the optical fiber sensor 30 can be basically performed by the position adjustment of the XYZ direction by the adapter member 27 and the sensor holder member 29 mentioned above, the dimension error which each member has, and the optical fiber sensor ( 30) The optical axis (focal position) of the optical fiber sensor 30 may shift from a target position by the manufacturing error of itself. In this case, the optical fiber sensor 30 is finely adjusted in the optical axis direction by rotating the eccentric collar 30a of the optical fiber sensor 30 described with reference to FIG. 4 with respect to the lens 30b. When the eccentric collar 30a is rotated, the focal position of the optical fiber sensor 30 also moves in the Z direction, but this movement in the Z direction is caused by re-adjusting the sensor holder member 29 in the Z direction with respect to the arm member 28. Can be offset.

In the sensor positioning jig 60 illustrated in FIG. 9, three jig position fixing parts 62 are provided, but at least one may be provided. Moreover, the head mounting plate 20a mentioned above becomes an attachment surface at the time of attaching the component holding head 10 to the X axis of the XY gantry of a surface mounter.

As described above, the sensor positioning jig 60 fixes the position in the R direction, that is, the R axis of the rotary head 40. Thus, by performing the home position adjustment of the R-axis based on the position of the fixed R-axis using the sensor positioning jig 60, the target position obtained by the above-described sensor position adjustment other than the actual device is separated within the actual device. Even when the calibration is performed, it is secured as the target position. In addition, at the assembly site of the actual device, the R servo motor 21 side and the rotary head 40 side are aligned with the encoder origin position of the R servo motor 21 according to the R axis (nozzle index) origin position of the rotary head 40. Tighten by coupling. At this time, since the home position adjustment of the nozzle index to be matched can also be performed using the sensor positioning jig 60, the error between the home position adjustment position at the assembly site and the home position on the actual apparatus can be suppressed. In addition, since the position of the nozzle 42 to be detected can also be secured by using the sensor positioning jig 60, an equivalent position can be ensured inside and outside the actual device, so that the quantity of light of the optical fiber sensor 30 can be checked and adjusted outside the actual device. You can do it.

In addition, although the optical fiber sensor 30 was used as a sensor which detects the nozzle 42 in the above embodiment, other non-contact sensors, such as a magnetic sensor, can also be used. Moreover, this invention is applicable also to component holding heads other than a rotary head type.

While aspects of the present invention have been described with reference to the embodiments shown in the accompanying drawings, this is merely exemplary, and various modifications and equivalent other embodiments are possible from those skilled in the art. You will understand the point. Accordingly, the true scope of protection of the invention should be defined only by the appended claims.

The present invention can be used in the manufacture and operation of component mounters.
