Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting machine for picking up components such as ICs by a head unit having a plurality of nozzle members and mounting them on a predetermined position of a printed circuit board. The present invention relates to a component recognizing device for a mounter that recognizes components.

[0002]

2. Description of the Related Art Conventionally, a head unit having a nozzle member for mounting a component sucks a component such as an IC from a component supply section and transfers it onto a printed circuit board that is positioned,
A mounting machine that is mounted on a predetermined position of a printed circuit board is generally known. Further, recently, in order to improve the mounting efficiency, a mounting machine has been proposed in which a plurality of nozzle members are arranged side by side on a head unit so that a plurality of components can be transferred at one time.

In such a mounting machine, there is some variation in the position of the component when the component is sucked by the nozzle member, and it is required to correct the mounting position according to the displacement of the component suction position. Therefore, the suctioned component is recognized to detect the displacement of the suction position with respect to the nozzle member, and the abnormality of the component, for example, if the component has a lead, the lead is broken.

As an apparatus for recognizing such a part, for example, a line sensor is installed on a base of a mounting machine, a head unit after picking up a part is passed through the line sensor, a part image is taken in, and the part is picked up. An apparatus has been proposed which recognizes a part based on an image.

[0005]

As described above, in the device for recognizing a part using a line sensor, a moving part image is captured one-dimensionally, so that a relatively simple shape such as a rectangular chip part is obtained. It is convenient to recognize parts such as the above parts and parts such as long connectors, but high accuracy is required because it may not be possible to recognize parts accurately when speed fluctuations occur in the parts. There is a case in which sufficient recognition accuracy cannot always be ensured for a part to be processed, for example, a flat package IC having a large number of leads.

Therefore, in the above-described mounting machine which recognizes components during mounting, it is desired to solve such problems and perform component recognition with high accuracy.

Particularly, in an apparatus in which a plurality of nozzle members are used to suck a plurality of components at a time in order to improve the mounting efficiency, it is necessary to accurately recognize the components while avoiding a decrease in the mounting efficiency as much as possible.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a component recognizing device for a mounting machine which can further enhance the component recognizing accuracy.

[0009]

According to a first aspect of the present invention, there is provided a component recognizing device for a mounting machine, which has a plurality of component suction nozzle members arranged in parallel and is movable between a component supply side and a component mounting side. In a mounting machine equipped with: a head unit, an imaging unit including a line sensor and an area sensor arranged in a moving path of the head unit, a driving unit for moving the head unit, and the head according to the type of the sucked component. Control means for selectively moving the unit to a predetermined image pickup position by the line sensor or area sensor, and controlling the drive means so as to cause the head unit to perform a predetermined image pickup operation corresponding to the line sensor or area sensor; And a component recognition unit that recognizes each of the suction components based on the component image captured by the imaging unit. It is intended.

A component recognizing device for a mounting machine according to claim 2 is
The component recognizing device according to claim 1, wherein the line sensor is arranged so as to extend in a direction orthogonal to an arrangement direction of the nozzle members, and the area sensor is a side portion of the line sensor, and the line sensor. The nozzles are arranged in parallel in the arrangement direction of the nozzle members.

[0011]

According to the first aspect of the present invention, since the line sensor and the area sensor are provided in the moving path of the head unit, these respective sensors are used properly according to the kind of parts to be recognized. . That is, when a component is imaged by the line sensor, the head unit is moved at a predetermined constant speed with respect to the line sensor, so that the component image of each component to be imaged that is adsorbed by the nozzle member is sequentially obtained. The parts are recognized and recognized. On the other hand, when an image of a part is picked up by the area sensor, by repeatedly moving and stopping the head unit with respect to the area sensor, the part image of each part of the picked-up object part picked up by the nozzle member is sequentially captured and Is recognized. Therefore, it becomes possible to selectively capture an image suitable for component recognition according to the type of the component to be mounted, and as a result, the component recognition accuracy is improved.

According to the second aspect of the invention, since the area sensor is arranged on the side of the line sensor in the arrangement direction of the nozzle members, that is, in the moving direction of the head unit with respect to the line sensor at the time of picking up an image of the part, the line sensor is arranged. The amount of movement of the head unit and the acceleration / deceleration operation when the component to be imaged by the sensor and the component to be imaged by the area sensor are simultaneously adsorbed by the head unit are reduced, which makes it possible to efficiently image the component. .

The Y-axis servomotor 9 and the X-axis servomotor 15 are respectively provided with position detecting devices 10 and 16 which are rotary encoders, by which the moving position of the head unit 5 is detected. It is like this.

The head unit 5 is provided with a nozzle member 21 for attracting chip components, and in this embodiment, eight nozzle members 21 are provided side by side in the X-axis direction as shown in FIG. Each nozzle member 21 moves up and down with respect to the frame of the head unit 5 (moves in the Z-axis direction).
And rotation about the nozzle center axis (R axis) is possible, and Z

On the other hand, a line sensor unit 23 and an area sensor unit 24 as image pickup means for picking up an image of the component sucked by each nozzle member 21 are arranged between the component supply section 4 and the conveyor 2. .

The line sensor unit 23 (hereinafter abbreviated as line sensor 23) is a line sensor body 23a.
And an illumination unit 23b composed of a large number of LEDs. Although not shown, the line sensor main body 23a includes image pickup elements arranged side by side in a direction (Y-axis direction) orthogonal to the arrangement direction of the nozzle members 21, and is formed in the illumination section 23b. A part image is one-dimensionally taken in through the slit portion.

On the other hand, the area sensor unit 25 (hereinafter abbreviated as the area sensor 25) is the line sensor 2
3 on the right side of the line sensor 23 in the illustrated example. The area sensor 25 is composed of an area sensor body 25a and a second illuminating section 25b composed of a large number of LEDs.

As shown in FIG. 1, the second illuminators 25b are provided in two rows in the Y-axis direction with the area sensor body 25a sandwiched therebetween, and are adsorbed by the nozzle member 21 to the area sensor body 25a. The front side of the component (actually the back side of the component) is irradiated with light.

The area sensor body 25a is, for example, C
It consists of a CD camera and is designed to capture component images two-dimensionally. Further, when the area sensor 25 performs the image pickup, the respective illumination sections of the first illumination section 24 and the second illumination section 25b provided in the head unit 5 selectively selectively according to the type of the component to be imaged. It is designed to emit light. Then, when the first illuminating section 24 emits light, an image (reflection image) obtained by reflecting the light on the surface of the component is captured, and the second illuminating section 25b.
When is emitted, an image (transmission image) obtained by transmitting the light through the component is captured.

At the time of mounting, after the components are sucked by the nozzle members 21 of the head unit 5, the head unit 5 causes the line sensor 23 and the area sensor 2 to move.
The images of the components picked up by being moved in the X-axis direction (the direction of the arrow Sa or Sb in FIG. 1) above 5 are sequentially taken in, and the image processing means 33 described later is provided as a predetermined image signal.
It is designed to be output to. Then, when the head unit 5 completely passes above the line sensor 23 and the area sensor 25, images of all the components sucked by the head unit 5 are captured.

Next, the control system of the mounting machine will be described with reference to FIG. FIG. 3 is a block diagram showing an example of a control system of the mounting machine.

In the figure, the Y-axis servomotor 9, the X-axis servomotor 15, and the nozzle member 21 of the head unit 5 are shown.

Further, the position detecting devices 10, 16, 18, 20 provided on each of these servo motors are electrically connected to the axis control means 31 of the controller 30.

The line sensor main body 23a of the line sensor 23 and the area sensor main body 25a of the area sensor 25 are respectively the image processing means 3 of the controller 30.
3 is connected to the image processing means 33.
Predetermined image processing is performed on the captured component image to recognize the suction component.

The controller 30 has a main control means 32.
Is provided, and the operation of the mounting machine related to component recognition and the like is centrally controlled by the main control means 32 based on mount data stored in a storage unit (not shown).

Specifically, the main control means 32 controls the axis control means 31 to take in the optimum component image for image recognition, according to the type of the component to be recognized, the head unit 5. Is selectively moved to a predetermined imaging position by the line sensor 23 or the area sensor 25. When the area sensor 25 captures an image of a component, the first illumination unit 2 is selected depending on whether the reflection image or the transmission image is captured.
4 or the 2nd illumination part 25b is made to light-emit selectively.

Further, the quality of the component is judged from the image recognition result in the image processing means 33 and the correction amount is calculated, and at the time of mounting, the mounting operation is carried out in consideration of the quality judgment and the correction amount. It controls the control means 31.

By the way, in the mounting machine, since the head unit 5 is provided with a plurality of nozzle members 21 and a plurality of components can be simultaneously transferred from the component supply section 4 to the printed circuit board 3, for example, a method shown in the flowchart of FIG. Based on the above, mounting data (mount data) such as the component suction position with respect to the head unit 5 so that the mounting efficiency is maximized
Is set.

To briefly explain, a recognition method suitable for recognizing each mounted component is first determined from the data on the type of the component to be mounted and the data of the component mounting position on the printed circuit board 3 (the recognition method Judgment; Step S
1). The determination of the recognition method will be described later.

Then, in consideration of the type of nozzle member 21 at the time of mounting, the replacement efficiency, etc., it is determined which nozzle position of the head unit 5 should pick up each component (nozzle optimization; step S2). Based on this, the component supply unit 4
Number of tape feeders 4a in each and each feeder 4a
Position (optimization of adsorption point; step S
3) Further, the mounting order is determined (optimization of mounting points; step S5).

When each condition, that is, the mounting data is determined in this way, it is judged whether or not the mounting efficiency with this data is optimum (tact time optimization; step S5), and the data finally judged to be the optimum data is selected. It is adopted as mount data.

Here, in order to determine the recognition method suitable for recognizing the mounted component, the recognition method can be determined based on, for example, the method shown in the flowchart of FIG.

First, depending on the type of the component, it is judged whether or not the transparent recognition, that is, the recognition based on the transparent image of the component is particularly preferable for the relevant component (step S10), and the transparent recognition is particularly performed like the flat package IC. If it is preferable, the area sensor 25 picks up an image of the component for transparent recognition.

In step S11, it is determined whether or not the component is within the field of view of the line sensor 23, that is, whether or not the line sensor 23 can physically capture the image. The image is picked up by 23 and the reflection recognition is performed.

On the other hand, in step S11, when the image pickup by the line sensor 23 is impossible, it is determined whether or not both the transmission recognition and the reflection recognition can be performed for the part (step S12). If both can be recognized, the area sensor 25 captures an image of the relevant part for transparent recognition, while for a part that can be recognized only by reflection recognition, this part is used as the area sensor. The image is picked up by 25 and the reflection recognition is performed.

In this way, the recognition method according to the component to be mounted can be determined. Although not used in this embodiment, the line sensor 23 may be provided with illumination for transmission and the line sensor 23 may employ transmission recognition based on component imaging.

Next, the component recognition operation of the mounting machine configured as described above will be described.

When the mounting operation is started in the mounting machine, the head unit 5 is moved to the component supply section 4, and the components are sucked by the nozzle members 21. When the suction of the components is completed, the head unit 5 moves for component recognition. Specifically, the head unit 5 includes the line sensor 23 and the area sensor 25.
After being set to the right or left of a predetermined movement path for, the position is moved from this position in the direction of arrow Sa or Sb in FIG. In this case, the moving direction of the head unit 5 is determined by the supply position of the component to be sucked last, and when the last component is sucked to the right side of the area sensor 25 or a position close to this, the head unit 5 is moved. 5 is moved in the direction of the arrow Sa, and when the last component is sucked on the left side of the line sensor 23 or at a position close thereto, the head unit 5 is moved in the direction of the arrow Sb. ing.

When the line sensor 23 captures images of all the components adsorbed on the head unit 5, the head unit 5 moves above the line sensor 23 at a predetermined constant speed while the illumination unit 23b emits light. To be made. Then, as the head unit 5 passes over the line sensor 23, the component images of the components sucked by the nozzle members 21 are sequentially captured by the line sensor 23, and the component recognition is performed based on the captured image.

On the other hand, when the area sensor 25 captures images of all the components attracted to the head unit 5,
When the head unit 5 is moved above the area sensor 25 and the recognition target component and the area sensor 25 correspond to each other, the head unit 5 is temporarily stopped for a predetermined imaging time at that position. While repeating such movement and stop, the head unit 5 causes the area sensor 2 to
Images of the components adsorbed by the nozzle members 21 as they pass above 5 are sequentially captured by the area sensor 25, and the components are recognized based on the captured images.

When the suction sensor is imaged by the area sensor 25 as described above, the first illuminating unit 24 and the second illuminating unit 25b are selectively emitted depending on the type of the component, whereby the reflected image is obtained. Alternatively, the transmission image is captured by the area sensor 25.

By the way, as described above, all the components adsorbed by the head unit 5 are moved to the line sensor 23 or the area sensor 25 during the movement from the component supply unit 4 to the printed circuit board 3.
This is an example of the case where an image is picked up using any of
It is also possible to pick up the component to be recognized by the line sensor 23 and the component to be recognized by the area sensor 25 by the head unit 5 at the same time, and image the component while properly using both units 23 and 25. In this case, the following operation is performed.

That is, when the head unit 5 picks up each component, the part to be recognized by the line sensor 23 and the part to be recognized by the area sensor 25 are continuously sucked separately on the left and right sides of the head unit 5. . For example, the components to be recognized by the area sensor 25 are adsorbed by the four nozzle members 21 on the left side (the left side in FIGS. 1 and 2) of the head unit 5, and the four components on the right side (the right side in FIGS. 1 and 2).
The component to be recognized by the line sensor 23 is adsorbed by the nozzle member 21.

After the head unit 5 is set to the right or left of the movement path for the line sensor 23 and the area sensor 25, it is moved from this position in the direction of arrow Sa or Sb in FIG.

Here, when the head unit 5 is moved in the direction of the arrow Sa, for example, as shown in FIG.
After the movement starts (time t1), the head unit 5 is accelerated to a predetermined movement speed V ₁ (Max value), and when the speed reaches the predetermined speed, the head unit 5 is moved at a constant speed and is brought close to the area sensor 25. Then, when the head unit 5 approaches the area sensor 25, the speed is decelerated, and the component adsorbed by the leftmost nozzle member 21 of the head unit 5, that is, the area sensor 2 is detected.
The leftmost component to be recognized by 5 is the area sensor 2
When the position corresponding to 5 is reached (at time t2), the head unit 5 is stopped and the area sensor 25 captures an image of the component. Then, while the head unit 5 is repeatedly moved and stopped, the parts adsorbed by the four nozzle members 21 on the left side of the head unit 5, that is, the parts to be picked up by the area sensor 25 are picked up (t.
2 to t3).

When the imaging of the parts to be recognized by the area sensor 25 is completed, the head unit 5 is accelerated again. Then, when a predetermined moving speed V ₂ with respect to the line sensor 23 is reached, the head unit 5 is moved at a constant speed. In this case, in the mounting machine, the time when the head unit 5 reaches the predetermined moving speed V ₂ (time t4).
At a later time, the acceleration of the head unit 5 or the arrangement interval between the area sensor 25 and the line sensor 23 so that the leftmost part of the parts to be recognized by the line sensor 23 reaches the position corresponding to the line sensor 23. Is set.

Then, the head unit 5 moves the above speed V ₂
Is moved at a constant speed and passes over the line sensor 23, so that the four nozzle members 21 on the right side of the head unit 5 are
An image of the component adsorbed on the substrate, that is, the component to be recognized by the line sensor 23 is captured (from time t4 to time t5).

When the image pickup of the component sucked by the rightmost nozzle member 21 of the head unit 5 is completed in this way, the head unit 5 is accelerated to a predetermined moving speed V ₁ and moved to the printed circuit board 3 side, and a predetermined amount. The mounting operation is performed.

As described above, according to the mounting machine of the above-described embodiment, the two types of image pickup means such as the line sensor unit 23 and the area sensor 25 are arranged on the base 1. You can use it at any time. Therefore, the degree of freedom of the captured image is increased as compared with the conventional mounting machine of this type in which the image of the component is captured by the single image capturing unit, and the image suitable for the type of the component to be recognized is selectively captured. As a result, it is possible to further improve the recognition accuracy of the parts. Moreover, in the image pickup of the component by the area sensor 25, the transmission image and the reflection image can be further captured by selectively causing the first illumination unit 24 or the second illumination unit 25b to emit light. The degree of freedom of is increased.

Further, in the above embodiment, the line sensor 23 and the area sensor 25 are arranged in parallel, and the area sensor 25 is arranged with respect to the line sensor 23 in the arrangement direction of the nozzle members 21, that is, the image pickup element arrangement direction of the line sensor 23. Since they are arranged in a direction orthogonal to the head unit 5, the head unit 5 simultaneously picks up a component to be recognized by the line sensor 23 and a component to be recognized by the area sensor 25 during the movement from the component supply unit 4 to the printed circuit board 3. By doing so, the parts can be imaged efficiently.

That is, when the line sensor 23 and the area sensor 25 are arranged separately from each other, for example, after picking up components, the head unit 5 is accelerated → moved at a constant speed (speed V
₁ ) → decelerates and moves to the area sensor 25 side, and while moving and stopping the head unit 5 here, imaging is performed by the area sensor 25, and then the head unit 5 accelerates again → moves (speed V ₁ ) → decelerates Then, it is necessary to move the head unit 5 to the line sensor 23 side and move the head unit 5 at a constant speed (speed V ₂ ). On the other hand, in the case of the mounting machine of the above-described embodiment, as described above, after the image is captured by the area sensor 25, the head unit 5 is accelerated to immediately move to the constant speed movement (speed V ₂ ). Since the image can be captured by the line sensor 23, both the movement amount and the acceleration / deceleration operation of the head unit 5 can be suppressed as compared with the case where the line sensor 23 and the area sensor 25 are arranged apart from each other. It is possible to image the parts.

The mounting machine is an embodiment of the mounting machine to which the example of the component recognition apparatus according to the present invention is applied.
The specific structure can be appropriately changed without departing from the scope of the present invention. For example, in the above embodiment,
The line sensor 23 and the area sensor 25 are arranged only between the one component supply unit 4 (upper side in FIG. 1) and the conveyor 2, but the other component supply unit 4 (FIG. 1).
The line sensor 23 and the area sensor 25 may be similarly provided between the lower side) and the conveyor 2.
By doing so, it is possible to quickly image the component even when the component is sucked by either of the component supply units 4, and as a result, the mounting efficiency can be improved.

[0057]

As described above, according to the component recognition apparatus of the present invention, the line sensor and the area sensor are provided in the moving path of the head unit, and when the line sensor images the component, the head unit is When a part image is picked up by the area sensor while the part image of each part to be picked up by the nozzle member is sequentially captured by moving it relative to the line sensor at a predetermined constant speed, and the part is picked up by the area sensor. In addition, while moving and stopping the head unit relative to the area sensor, the component image is sequentially captured for each component of the imaging target component adsorbed to the nozzle member to perform component recognition. This increases the degree of freedom of the captured image. Therefore, the recognition accuracy of the component can be further improved by selectively capturing the image suitable for the component recognition according to the type of the component.

Further, in such a configuration, if the area sensor is arranged on the side of the line sensor in the arrangement direction of the nozzle members, that is, in the moving direction of the head unit with respect to the line sensor at the time of picking up an image of the component, the line sensor can be used. It is possible to reduce the movement amount and the adjustment operation of the head unit when the component to be imaged and the component to be imaged by the area sensor are simultaneously adsorbed to the head unit, and thus the component can be efficiently imaged.
