Description

  The present invention relates to a component mounter, and more particularly, to a component mounter including an opening region that varies depending on production status.

  Each component mounting machine used in a component mounting line for mounting components on a board is fully automated during normal operation, and therefore usually does not require human approach.

  On the other hand, when a new component is added to the component mounter or maintenance of the component mounter is performed, a person needs to approach. In such a case, the operation of the component mounter is interrupted and maintenance is performed. However, when there is a person in the vicinity of the component mounter, it is necessary to ensure safety by preventing the component mounter from operating unexpectedly.

  Therefore, conventionally, an area sensor that can detect whether or not a human body is present near the component mounter is provided, and a human body is detected within a predetermined range set as a human body detection target range near the component mounter. An interlock is provided so that the component mounting machine does not operate.

In particular, Patent Document 1 limits the human body detection target range to the opening of a component mounter, thereby facilitating the installation of an area sensor and the possibility of intrusion of a part of a human body (for example, a hand). A component mounter capable of reliably interlocking a high opening is disclosed.
JP-A-11-150399

  However, in many cases, the opening of the component mounting machine is a part through which a board or a component for mounting on the board passes. Therefore, in the invention described in Patent Document 1, the sensor that triggers the interlock is a human body. It must be limited to sensors that can only detect. In other words, if a sensor that can detect substances other than the human body is used as an interlock trigger, the interlock will be applied even if the substrate that is loaded and unloaded in the normal process passes through the opening. is there. In addition, since a part of the opening of the parts supply unit is filled with a device called a feeder for supplying parts, a sensor that can detect substances other than the human body is used to set the detection target range as the whole opening. It is very difficult to do.

  Furthermore, when only the human body is detected, if an object other than the human body, for example, a working tool or the like remains in the opening, it cannot be detected by a human body detection sensor. The component mounter interlock will not be applied. In this case, the case where the movable part of a component mounting machine collides with a tool etc., and a component mounting machine may be damaged.

  The present invention has been made in view of the above problems, and even when a sensor capable of detecting not only a human body but also a foreign object is employed, it can be easily attached to an opening and can flexibly respond to production conditions. An object of the present invention is to provide a component mounter capable of performing the above.

  In order to achieve the above-described object, a component mounter according to the present invention is a component mounter that mounts components on a board, and has an opening area that varies depending on production conditions, and a foreign object intrusion into the opening area. And detecting means whose mounting position is variable as the opening area varies.

  As a result, even if a detecting means for detecting not only a human body but also a foreign object is employed, the detecting means can be attached while avoiding necessary members in a normal process, and the intrusion of a foreign object can be effectively detected. Become.

  It is desirable that the detection means can be attached to a boundary portion between the opening area and another area.

  Thereby, it becomes possible to detect a foreign material over the whole opening area.

  The opening area is an empty area where a feeder of a component supply unit in which a plurality of feeder attachment portions to which a feeder for supplying components is attached is arranged is not attached, and the detection means can be attached to the feeder attachment portion. It is desirable to be.

  As a result, it is possible to separate the foreign substance and the feeder that enter from the opening area of the component supply unit having a very large fluctuation, and to effectively detect only the foreign substance.

  Furthermore, a production condition acquisition unit that acquires the production condition, an opening region specification unit that specifies the opening region from the acquired production condition, and a position where the detection unit is attached is determined based on the specified opening region. It is preferable to provide an attachment position determination means.

  Thereby, since the attachment position of the detection means is automatically determined, it becomes possible to avoid human error in advance.

  Furthermore, it is preferable to provide display control means for displaying the attachment position of the detection means determined by the attachment position determination means.

  Thereby, since an operator etc. can confirm visually, it becomes possible to change the position of a detection means easily.

  The detection means may include a moving means for moving the detection means based on the attachment position of the detection means determined by the attachment position determination means.

  As a result, the mounting position of the detection means is automatically changed, and it becomes possible to reliably detect the intrusion of foreign matter into the opening region without a human error.

  In order to achieve the above object, the mounting position determination method according to the present invention is a detection means for detecting entry of foreign matter into an opening area of the component mounter with respect to the component mounter for mounting the component on the board. An attachment position determination method for determining an attachment position of a production method, a production condition acquisition step for acquiring production conditions, an opening area specification step for specifying the opening area from the acquired production conditions, and a specified opening area And a mounting position determining step for determining a position for mounting the detection means.

  If the attachment position is determined by this method, the attachment position of the detection means can be changed reliably.

  The method can be realized using a computer by a program, and the operation and effect thereof are the same as described above.

  According to the present invention, even when the opening area changes, a foreign object including a human body that passes through the opening area and a member that normally passes or exists outside the opening area are properly separated, and only foreign objects necessary for detection are detected. Will be able to.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an external perspective view showing a component mounter 100 according to an embodiment of the present invention.

  A component mounting machine 100 shown in the figure is an apparatus that can be incorporated into a mounting line. An electronic component is mounted on a substrate 20 received from an upstream side through an opening (not shown), and a predetermined number of electronic components are mounted. This is a device that sends the mounted substrate 20 downstream through the opening 200.

  The component mounter 100 shown in the present embodiment is a modular device that can hold a plurality of components at once with a multi-mounting head 112, transport the component, and mount it on a substrate. A robot 113 and a component supply unit 115 to which a tape feeder described later is attached are provided.

  Specifically, the component mounting machine 100 can not only mount minute components, but can also mount odd-shaped components such as connectors, large electronic components of 10 mm square or more, and switches / connectors with the same device. The component mounter is a multifunctional component mounter 100 capable of mounting IC components such as QFP (Quad Flat Package) and BGA (Ball Grid Array). Moreover, since these mounting speeds are high, such a component mounting machine 100 is called a high-speed multi-function machine. This embodiment shows an embodiment of the present invention, and the term “high-speed multi-function device” described here also shows an example of “component mounting machine” described in the claims. This is only what is specifically described. In other words, the term “component mounter” should be interpreted widely, and at least a device that contributes to component mounting (for example, a solder printer, reflow device, or inspection device) is included in “component mounter”. It is.

  The multi mounting head 112 includes a plurality of suction nozzles that hold electronic components by vacuum suction, and has a function of transporting the electronic components suctioned and held by the nozzles at a time and sequentially mounting them on the substrate 20.

  The XY robot 113 is a robot for moving the multi-mounting head 112 such as above the component supply unit 115 and the substrate 20 to a predetermined place in the horizontal plane, and a driving force is given by the driving source 111.

  The component supply unit 115 is a portion that exists in the vicinity of the opening 200 to which the tape feeder is attached and detached, and supplies the component held by the tape fed out by the tape feeder to the multi-mounting head 112. Moreover, the area | region where the tape feeder is not attached in the component supply part 115 becomes the opening area | region 201 (refer FIG. 2). Accordingly, the opening area 201 varies depending on the number and position of the tape feeders 114 that are one of the production conditions. In addition to the tape feeder, the component supply unit 115 is also attached with a component recovery device for recovering components that are sucked in an abnormal posture.

  Here, the opening area means an area in the opening of the component mounter that fluctuates depending on the production status (production conditions). In the present embodiment, an opening region in the component supply unit 115 and an opening region in the board loading / unloading port will be exemplified (the two opening regions will be described in detail later).

FIG. 2 is a plan view showing the main configuration of the component mounter according to the present embodiment.
The component mounter 100 further includes a fixed rail 121, a movable rail 122, and a detection unit 210 that constitute a track for transporting the substrate 20. A tape feeder 114 is inserted into the component supply unit 115. Note that the tape feeder 114 is not inserted into a part of the component supply unit 115 shown on the lower side in the drawing, and the part is an opening region 201a (a region where the tape feeder is indicated by a broken line).

  The tape feeder 114 is a device that can sequentially feed out the tape in order to supply a large number of electronic components continuously held in the length direction of the tape to the multi-loading head 112. A necessary number of tape feeders 114 are attached to the component supply unit 115 according to the type of the substrate 20 on which the components are mounted. Accordingly, since the number of tape feeders 114 to be inserted into the component supply unit 115 differs depending on the type of the substrate 20 which is one of the production conditions, the opening area 201a existing in the component supply unit 115 also varies depending on the production conditions. Will do. Further, the position where the tape feeder 114 is arranged is determined in advance according to the production conditions so that the tape feeder 114 can be efficiently mounted, and the opening area 201a also varies according to this arrangement.

  The fixed rail 121 and the movable rail 122 have a function of a conveyor that conveys the substrate 20 placed on these rails in a bridging manner. The movable rail 122 can change the distance from the fixed rail 121 according to the size (width) of the substrate 20 which is one of the production conditions, so that the movable rail 122 can correspond to various substrates 20. It has become. Therefore, when the position of the movable rail 122 differs according to the size (width) of the substrate, which is one of the production conditions, the opening area 201b included in the component mounting machine 100 varies.

  In the claims and the specification, the “opening portion 200” indicates a portion where the component mounter 100 is open. On the other hand, the “opening area 201” indicates an area where foreign material intrusion that is distinguished from regular members such as the tape feeder 114 and the substrate 20 should be detected. The opening area 201 is included in the opening 200.

  The detection unit 210 is attached to a boundary portion between the opening area 201 and another area and has a function of detecting a foreign substance passing through the opening area 201. The component mounter 100 is provided with detection means 210 at each boundary portion between the opening area 201b of the opening into which the board 20 is carried in and the opening area 201b of the opening through which the board 20 is carried out. Further, the detection means 210 is also provided at the boundary portion of the opening region 201a where the tape feeder 114 of the component supply unit 115 is not attached. Details of the detection means will be described later.

FIG. 3 is a perspective view schematically showing the component supply unit 115.
As shown in the figure, the component supply unit 115 includes a number of rail-like feeder attachment portions 116 to which the tape feeder 114 can be attached and detached in parallel. The feeder attachment portion 116 includes a dovetail groove 117 (a groove portion wider in the interior than the inlet) that opens upward and extends in the length direction, and has a convex cross section provided in a projecting manner at the lower portion of the tape feeder 114 shown in FIG. By engaging with the protrusion 118, the tape feeder 114 can be firmly held.

  In addition, the tape feeder 114 is attached to a part of the center of the feeder attachment portion 116 of the component supply unit 115, and other portions (the portion indicated by the broken line in the drawing) where the tape feeder 114 is not attached are as follows. , An opening region 201a.

  In the case of the detection unit 210 attached to the component supply unit 115, the detection unit 210 includes a light projecting unit 210a, a light receiving unit 210b, and a fixture 211. Further, the detection unit 210 includes two fixtures 211 that are similar in appearance to the tape feeder 114 shown in FIG. 4, and these two fixtures 211 are respectively a light projecting unit 210a and a light receiving unit 210b. And are attached. Here, since the fixture 211 provided with the light projecting unit 210a and the fixture 211 provided with the light receiving unit 210b are both approximate to the external appearance tape feeder 114, the specific mode of the detection means is hereinafter referred to as “dummy feeder”. I write.

  5A and 5B are plan views showing the dummy feeder. FIG. 5A is a dummy feeder provided with a light projecting unit, and FIG. 5B is a dummy feeder provided with a light receiving unit. In practice, the two fixtures 211 are arranged in parallel, and the light projecting unit 210a and the light receiving unit 210b are opposed to each other. However, for the sake of easy explanation, the opening region 201a shown in FIG. 3 is viewed from the front. The state (in the direction of the arrow in FIG. 3) is shown in a state in which each dummy feeder is pseudo-rotated so that the opposing surfaces of the pair of dummy feeders can be seen on the front side.

  As shown in the figure, the fixture 211 has an appearance that is substantially the same as that of the feeder 114, and is provided with a protrusion 118 similar to the feeder 114 on the lower surface.

  The light projecting unit 210a is a device that projects light L (for example, laser light) toward the light receiving unit 210b, and can project light L from the upper end to the lower end of the opening region 201a.

  The light receiving unit 210b is a device capable of transmitting a signal when the light L projected from the light projecting unit 210a is interrupted, and foreign matter is present at any position from the upper end to the lower end of the opening region 201a. Even if the light is interrupted, the state can be detected, and information indicating that can be transmitted.

  A fixture 211 (hereinafter referred to as “dummy feeder 220a”) to which the light projecting portion 210a is attached and a fixture 211 to which the light receiving portion 210b is attached (hereinafter also referred to as “dummy feeder 220b”) are illustrated. As shown in FIG. 3, it is attached in the same manner as the tape feeder 114 using a ridge 118 to a feeder attachment portion 116 existing at the boundary between the opening region 201a on the left side of the feeder 114 and another region. Similarly, the opening region 201a on the right side of the feeder 114 is also attached to the feeder attachment portion 116 existing at the boundary with the other regions. The dummy feeder 220 includes a connector 120 at the same position as the tape feeder 114. When the dummy feeder 220 is attached to the feeder attachment portion 116, a connector (not shown) on the component mounting machine 100 side and the dummy feeder 220 are provided. The side connector 120 is connected.

  As a result, power can be supplied from the component mounter 100 by simply attaching the dummy feeder 220 to the feeder mounting portion 116 of the component supply unit 115, and information can be exchanged with the component mounter 100.

  The dummy feeder 220a is provided with a power supply board 221. The power supply board 221 is a board for converting the power received from the component mounting machine 100 via the connector 120 so that the light projecting unit 210a can project light and supplying power to the light projecting unit 210a.

  The dummy feeder 220b includes a control board 222 and an interface (I / F) 223.

  The control board 222 is a board for removing noise from the signal obtained from the light receiving unit 210b, amplifying only the signal indicating that the light L is blocked, and transmitting it as information indicating that.

  The interface 223 is a board for adjusting a communication protocol or the like so that information received from the control board 222 can be transmitted to the component mounter 100 via the connector 120.

  In the case of the dummy feeder 220b as well, power is supplied to the control board 222, the interface 223, and the light receiving unit 210b.

FIG. 6 is a block diagram showing the functional unit of the component mounting machine together with the mechanism unit.
As shown in the figure, the functional unit 300 of the component mounting machine 100 has a function capable of stopping the movable part (for example, the XY robot 113) of the component mounting machine 100 based on the information received from the dummy feeder 220b. A communication I / F 301, a mounting machine control unit 302, an operation sound generation unit 304, an operation panel display unit 305, and an operation light emitting unit 306.

  The communication interface 301 is a processing unit that acquires information as to whether or not an intrusion of foreign matter has been detected while matching the dummy feeder 220b with a communication protocol.

  The mounting machine control unit 302 is a processing unit that analyzes a signal from the dummy feeder 220b and determines whether or not a foreign object has entered the opening area 201a. Further, when the mounting machine control unit 302 determines that a foreign object has entered, in particular the movable mechanism (for example, the XY robot 113, the multi-mounting head 112, the board transport mechanism (the fixed rail 121 and the movable rail) of the mechanism unit of the component mounting machine 100). 122, and a processing unit that transmits a signal for stopping the movement of the movable rail 122).

  The motion sounding unit 304 is a processing unit that, when receiving a signal for stopping the movement, sounds a buzzer 401 provided in the component mounting machine 100 and notifies that the component mounting machine 100 is stopped by the sound. .

  When the operation panel display unit 305 receives a signal for stopping the movement, the component mounting machine 100 is stopped by displaying an image or a character on a liquid crystal monitor with a touch panel, which is a display device 402 included in the component mounting machine 100. It is a processing unit that notifies that a state has been reached.

  When the operation light emitting unit 306 receives the signal for stopping the movement, the operation light emitting unit 306 blinks the light emission notification device 403 (for example, Patlite (registered trademark)) included in the component mounting machine 100, and the component mounting machine 100 is stopped by the light. It is a processing unit that notifies that a state has been reached.

  With the above configuration, when a foreign object passes through the opening area 201a or when a foreign object exists, a part of light from the light projecting unit 210a cannot reach the light receiving unit 210b due to the foreign object. The control board 222 included in the dummy feeder 220b on the side determines that the state is the passage (intrusion) of the foreign matter and transmits the signal to the component mounter 100 via the i / f 223 and the connector 120.

  The mounting machine control unit 302 that has received the signal via the communication I / F 301 stops the movement of the XY robot 113, the multi-mounting head 112, the substrate transport mechanisms 121 and 122, the movable rail 122, and notifies that effect. To do.

  As a result, it is possible to avoid danger to the human body that has entered the opening area 201a, and the moving part stops even when a foreign object such as a tool is present in the opening area 201a. It is also possible to avoid damage to the component mounter 100 due to a collision.

  Further, by using the detection unit 210 as the dummy feeder 220, the dummy feeder 220 can be attached to the feeder attachment portion 116 of the component supply unit 115 in the same accurate positional relationship as the normal tape feeder 114. Accordingly, it is possible to detect a foreign object without adjusting the positional relationship between the light projecting unit 210a and the light receiving unit 210b after the dummy feeder 220 is attached.

  Further, even if the type of the substrate 20 to be mounted is changed and the number and position of the tape feeders 114 are changed to change the width of the opening area 201a, the feeder attachment for attaching the dummy feeder 220 is caused by the change. Since foreign matter existing in the opening area 201a can be detected only by changing the part 116, it becomes possible to flexibly cope with production conditions.

FIG. 7 is a block diagram illustrating a functional unit for determining the attachment position.
The attachment position determination processing unit 500 shown in the figure is realized as a functional unit included in the component mounter 100, and includes a production condition acquisition unit 501, an opening area specifying unit 502, an attachment position determination unit 503, and a display. A control unit 504 and an attachment position determination unit 505 are provided.

  The production condition acquisition unit 501 extracts and acquires data necessary for determining the mounting position of the detection unit 210 from data such as production conditions given from the host computer and production conditions held by the component mounting machine 100. It is a processing unit. Here, the production conditions are mounting position data for instructing a position for mounting a component on the board, component data for instructing an operating condition such as a component shape and a speed for mounting the component, and a component arrangement of the component supply unit (feeder Component arrangement data indicating the (array), etc., which is related to the present embodiment is the component arrangement data.

  Note that the component collection device is a device for collecting components that need to be discarded due to a suction error of the multi-mounting head 112 or the like, and is a device that is attached to the feeder attachment portion 116 in the same manner as the tape feeder 114. .

  The opening area specifying unit 502 is a processing unit that deletes the position where the tape feeder 114 and the parts collection device are attached from all the data of the feeder attaching part 116 provided in the component supply part 115 and specifies the remaining area as the opening area 201a. .

  The attachment position determination unit 503 is a processing unit that determines the feeder attachment unit 116 located at the boundary with the other region of the opening region 201 a specified by the opening region specification unit 502 as the attachment position of the detection unit 210. Further, the attachment position determination unit 503 specifies whether the determined feeder attachment part 116 is located on the left or right boundary of the opening region 201a and attaches the dummy feeder 220a including the light projecting part 210a. It is also determined whether the dummy feeder 220b provided with the light receiving unit 210b is attached.

  The display control unit 504 is a processing unit that creates an image in which the attachment position of the dummy feeder 220 can be clearly understood based on the information determined by the attachment position determination unit 503 and transmits the image data to the display device 402.

Next, the processing operation of the attachment position determination processing unit 500 will be described.
FIG. 8 is a flowchart showing the processing operation of the attachment position determination processing unit 500.

  First, the production condition acquisition unit 501 acquires component arrangement data from the production conditions necessary for specifying the opening area 201a provided from the host computer or the like (S101).

  Next, the opening region specifying unit 502 specifies the opening region 201a based on the data of the feeder attaching unit 116 acquired in advance and the attachment position of the tape feeder 114 and the component collecting device obtained from the component arrangement data (S103). ).

  Next, the attachment position determination part 503 determines the feeder attachment part 116 located in the boundary with the other area | region of the specified opening area | region 201a as an attachment position of the detection means 210 (S105).

  Next, the display control unit 504 creates an image indicating the attachment position of the dummy feeder 220 and displays it on the display device 402 (S107).

FIG. 9 is a conceptual diagram showing an image created by the display control unit 504.
The image shown in the figure schematically displays the component supply unit 115 viewed from the direction indicated by the arrow in FIG. 3, and the display device 402 displays a square as a symbol symbolizing the feeder attachment unit 116 side by side. Has been. The position where the tape feeder 114 is attached is marked with a cross, and a graphic symbolizing the tape feeder 114 is displayed. Further, a position where the dummy feeder 220 is attached is marked with a circle, and a graphic symbolizing the dummy feeder 220a including the light projecting unit 210a and the dummy feeder 220b including the light receiving unit 210b is displayed thereon. Further, below the square marked with a circle, there are characters indicating the specific position of the feeder mounting portion 116 and characters indicating whether the dummy feeder 220a on the light emitting side or the dummy feeder 220b on the light receiving side is to be mounted. Is displayed.

  Next, the attachment position determination unit 505 shown in FIG. 7 specifies which feeder attachment unit 116 the dummy feeder 220 is attached to, and specifies the type of the attached dummy feeder 220, and the attachment position determination unit 503. Based on the information determined in step S109, it is determined whether the attachment position of the dummy feeder 220 actually attached is correct (S109). Further, when it is determined that the display control unit 504 is not normally attached as a result of the determination, the display control unit 504 creates an NG image (S111) and transmits the image data to the display device 402.

  Here, the dummy feeder 220 is individually provided with identification information for identifying the dummy feeder 220, and has a function of transmitting the information to the component mounter 100 via the connector 120. In addition, the component mounting machine 100 has a function of being able to individually identify a plurality of feeder attachment portions 116 and identifying which feeder attachment portion 116 is receiving a signal from the connector 120. (For example, this can be realized by assigning a unique port number to each connector). Based on these functions, the attachment position determination unit 505 determines the attachment position and type of the dummy feeder 220.

  FIG. 10 is a conceptual diagram showing an NG image created by the display control unit 504 based on information from the attachment position determination unit.

  As shown in the figure, the display device 402 displays the position where the dummy feeder 220 is actually attached, and when the attachment position determined by the attachment position determination unit 503 is different from the actual attachment position, That part is indicated by an arrow so that attention can be drawn.

  As mentioned above, although embodiment of this invention was described, this invention is not necessarily limited to the said embodiment. For example, although the embodiment in which the communication between the dummy feeder 220 and the component mounter 100 is wired via the connector 120 is shown, this is not the only example. For example, the dummy feeder 220 may include an interface for wireless communication, and may exchange information with the functional unit of the component mounter 100 by wireless communication. In addition, the component mounter 100 does not need to include the mounter function unit 300 inside, and a computer separate from the component mounter 100 may include the mounter function unit 300. The same applies to the attachment position determination processing unit 500.

  Furthermore, some component mounting machines 100 do not supply power to the tape feeder 114. Therefore, a battery may be mounted on the dummy feeder 220, and the light projecting unit 210a and the light receiving unit 210b may be driven and communicated based on the power from the battery.

  Further, the dummy feeder 220 may include an RFID (Radio frequency identification) in which its own identification information is stored. On the other hand, if the multi-mounting head 112 is provided with a reader for reading RFID information, the component mounter 100 can acquire whether or not the dummy feeder 220 is attached, the attachment position, and the type of the dummy feeder 220. In this case, it is preferable that the RFID is attached at a position similar to the position where the multi-mounting head 112 sucks components from the tape feeder 114.

  Further, the dummy feeder 220 has been described as including the protrusion 118 that engages with the dovetail groove 117 of the feeder attachment portion 116 as with the tape feeder 114, but instead of the protrusion 118, the dummy feeder 220 includes a magnet-type base portion. Alternatively, the dummy feeder 220 may be attached to the feeder attaching portion 116 or the like by adsorption by magnetic force.

Next, other attachment positions of the detection unit 210 will be described.
FIG. 11 is a plan view of the opening through which the substrate passes viewed from the substrate passing direction.

  As shown in the figure, the light projecting unit 210a of the detecting means 210 is attached to the movable rail 122, and the movable rail 122 moves according to the size of the substrate 20, which is one of the production conditions. The attachment position of the part 210a with respect to the component mounting machine 100 is changed.

  The light receiving unit 210b of the detection unit 210 is attached to the housing of the component mounting machine 100, and the mounting position of the light receiving unit 210b is not changed.

Next, another embodiment will be described.
FIG. 12 is a perspective view showing another embodiment.
