Description

The present invention is a pick-and-place automatic mounting apparatus for mounting electrical and / or optical components on a substrate,
A base unit is provided, and the base unit extends in the longitudinal direction and is aligned substantially in parallel, and the first and second supports, and the first and second supports. A mounting range for supplying at least one substrate between which electrical and / or optical components are mounted,
In addition, a first gantry unit is provided, and the first gantry unit is mounted on the substrate located in the mounting range, which is movably attached to one gantry arm and the gantry arm. The present invention relates to a type equipped with a mounting head for carrying out.

  Such a type of automatic mounting device is known from the prior art. That is, for example, US Pat. No. 5,0024,448 discloses a pick-and-place type automatic mounting apparatus including two parallel supports extending in a longitudinal direction and two gantry. In this case, each gantry is guided by guide rails on both sides, and these guide rails are respectively fixed to the support. Each gantry is provided with a mounting head movable along the gantry. The mounting head serves to pick up electronic components and mount the electronic components on a circuit board or printed wiring board. Based on the support on both sides, such an automatic mounting device has a relatively high accuracy. However, due to the support on both sides, the approach to the automatic mounting device, especially the approach to the mounting range when approaching the automatic mounting device, such as when playing with individual gantry and working, etc. is greatly limited. .

  Furthermore, a known pick-and-place automatic mounting device based on German patent specification 10016130 has two parallel supports and guide rails respectively attached to these supports. ing. Each support is guided with one gantry arm that is guided only on one side. In this case, the non-guided ends of the gantry arms are formed so as to protrude freely. Such an automatic mounting device has a smaller positioning accuracy based on the freely projecting configuration of the gantry arm. However, the gantry's motor play and the approach to the machine, especially the approach to the supply unit and the mounting range, for example, are improved.

  However, the automatic mounting device is used to manufacture different products during the operating time. These products may differ from one another in part, for example, in terms of their printed wiring board size, number of components or component diversity.

  A disadvantage of the known prior art is that after the user has decided on one machine type, the automatic mounting device is often adapted only on a very limited scale to the production parameters that have been changed in some cases when the product is changed. In this way, a new product must be manufactured under more unfavorable conditions depending on circumstances.

  Accordingly, it is an object of the present invention to improve a pick-and-place automatic mounting apparatus for mounting electrical and / or optical components on a substrate of the type described at the outset, as needed. To provide an automatic mounting device that can flexibly meet the increased accuracy requirements, that is, can freely meet the requirements, or has a good approach to the machine and a high flexibility or flexibility during gantry movement It is.

The challenge is a pick and place automatic mounting device for mounting electrical and / or optical components on a substrate:
A base unit is provided, the base unit being aligned substantially parallel and extending in the longitudinal direction, namely a first and a second support, and the first second A mounting range for supplying at least one substrate to which electrical and / or optical components are mounted, which are located between the supports of
A first gantry unit is provided, the first gantry unit being mounted on a substrate located in the mounting range, movably attached to one gantry arm guided on both sides, and the gantry arm; Having a mounting head for mounting components, each end region of a gantry arm guided on both sides being guided and / or supported by first and second supports In
The automatic mounting apparatus is formed so that the first gantry unit can be replaced with a second gantry unit, and the second gantry unit includes one gantry arm guided on one side, and the gantry unit. A mounting head for mounting the component on a substrate positioned in the mounting range, which is movably attached to the arm, and one end range of the gantry arm guided on one side is a first end range. It is solved by an automatic mounting device for mounting electrical and / or optical components on a substrate, characterized in that it is guided by a support of the substrate.

The above problem is a pick-and-place automatic mounting apparatus for mounting electrical and / or optical components on a substrate:
A base unit is provided, the base unit being aligned substantially parallel and extending in the longitudinal direction, i.e. a first and a second support, and the first second A mounting range for supplying at least one substrate to which electrical and / or optical components are mounted, which are located between the supports of
A second gantry unit is provided, the second gantry unit being mounted on a substrate located in the mounting range, which is movably attached to one gantry arm guided on one side; A mounting head for mounting components, and one end range of the gantry arm guided on one side is guided by the first support,
The automatic mounting device is formed so that the second gantry unit can be replaced with the first gantry unit. The first gantry unit includes one gantry arm guided on both sides, and the gantry unit. A mounting head that is movably attached to the arm and for mounting the component on a board located in the mounting range, and each end range of the gantry arm guided on both sides is a first and a second It is also solved by an automatic mounting device for mounting electrical and / or optical components on a substrate, characterized in that it is guided and / or supported on a second support.

  From an automatic device with one gantry arm guided on both sides, for example with increased accuracy, for example with improved motor play and improved approachability to at least part of the automatic mounting device Based on the fact that the automatic mounting device can be recombined into one gantry arm guided on one side, the automatic mounting device can be flexibly adapted to the requirements imposed on the automatic mounting device by various products to be manufactured, for example. It becomes possible to adapt to.

  In order to be able to be exchanged between the various gantry, the automatic mounting device and thereby the gantry which can be used correspondingly must be specially adapted. This is because, due to the high accuracy requirements that are generally present when components are mounted, it has been necessary in the past to firmly assemble the entire gantry structure.

  In particular, automatic mounting devices and gantry must be adapted to the special conditions that arise based on the fact that a gantry supported and / or guided on both sides can be replaced by a gantry arm guided on one side. This can occur, for example, on the basis of the variously formed drive mechanisms in the gantry type, or often on the basis of different loads on the bearing part, the guide part and / or the mechanical support structure. In the following, such a possible configuration will be described in detail.

  The electrical component may be, for example, a housing-sealed or non-housing-sealed (eg so-called Bare Dies) electrical or electronic semiconductor component. Such an electrical component may be, for example, an active component, such as a logic component, an amplifier component or any kind of integrated circuit. Furthermore, the electrical component may be a passive component such as a resistor, a capacitor or a coil. Furthermore, the electrical components may be formed as connection elements, for example connectors or other contact elements.

  The optical component can be, for example, any kind of lens or beam guiding element. Furthermore, the electrical components may be formed as electro-optical components, such as lasers, light emitting diodes or optical beam guiding elements and amplification elements. In particular, electrical and / or optical components may be formed as so-called SMD components (SMD: Surface Mounted Device) for surface mounting.

  Furthermore, the electrical and / or optical components may be formed as a configuration assembly consisting of a plurality of electrical and / or optical components.

  The substrate can be, for example, a circuit support, in particular a printed circuit support (eg Printed Circuit Boards (PCB)) or a metal support and / or plastic support for electrical and / or optical components. It may be formed as a body. Furthermore, one board | substrate may be formed as a conductor plate, a panel, or a support substrate.

  The parallel supports, i.e. the first support and the second support, are aligned substantially in parallel, in particular the guides and / or drive components respectively arranged corresponding to the supports are approximately parallel. It may mean that the position is adjusted. “Substantially parallel” means, in the present specification, in particular that the supports are parallel within the framework of the conditions given for the construction and the required accuracy of the automatic mounting device. In particular, the term “parallel” is used herein to mean an angular deviation of less than 1 ° between the supports or between the guides arranged corresponding to the supports and / or between the drive elements, or more than 5 °. Can also mean a small angular deviation.

  The mounting range can be, for example, a spatial range in which one or more mounting heads of the automatic mounting apparatus can pick up, ie pick up and / or put down again, ie place down.

  The preparation or supply of the substrate can be performed, for example, by storing or holding the substrate in a substrate transfer apparatus. The substrate transport device may be adjusted to carry the substrate into and out of the mounting range. In this case, the substrate may be placed, for example, on the substrate transfer device and / or fixed at a predetermined mounting position by the substrate transfer device. Furthermore, it is possible to deliver the substrate from the substrate transfer device to a special position fixing device for mounting.

  A gantry arm guided on both sides of a first gantry unit guided and / or supported by a first support and a second support at each end range is such that the gantry arm is a first support. It may be formed so as to be guided by both the body and the second support. Further, the gantry arm may be formed such that the gantry arm is guided by one of the supports and is simply supported by the other support. .

  In the present specification, “guidance” is understood to limit the degree of freedom perpendicular to the direction of movement of the gantry, but “support” is used herein to mean a predetermined movement of the gantry. It is understood that even in a direction perpendicular to the direction (eg along the support axis), still allow freedom of movement. Such a support part may be formed, for example, as a mounting part under the use of a traveling roller or an air bearing, for example.

  Furthermore, the first gantry unit may be driven, for example, on both sides or alternatively only on one side. In the case of driving on both sides, the driving can be carried out in each end range of the gantry arm. Such a drive can be performed, for example, by a worm gear drive, a spindle drive, a gear drive, a step motor or a linear motor. The configurability for the drive listed above also applies to all other gantry drives described herein.

  In the case of double-sided drive using a linear motor, for example, one magnet rail may be attached to each of the first support body and the second support body. One corresponding linear motor drive unit for interacting with each magnet rail may be attached. In the case of double-sided drive using a spindle drive device, for example, one rotatably supported spindle may be disposed on the first support and the second support, respectively. In that case, the spindle interacts with a corresponding corresponding element, each attached to the end region of the gantry unit.

  The driving of the first gantry unit on one side is performed by, for example, an alternative configuration of the driving device mentioned above, for example, a linear motor driving device as described above or a spindle driving device as described above. Can be broken.

  In general, the drive of the first gantry unit may be formed, for example, such that an active drive component is present in the gantry unit (eg a drive unit for a linear motor drive). Furthermore, the drive device may be formed such that the active component is part of the base unit (eg a drive spindle of a spindle drive device).

  The guidance of the gantry arm can be performed directly in relation to the drive device of the gantry arm, for example, or one or more guide elements arranged separately from the drive element, for example one attached to the support Alternatively, it may be performed by a plurality of guide rails and one or more guide carriages which are movable or movable along the guide rails.

  The drive device for the gantry arm guided on one side of the second gantry unit may be formed as a spindle drive device or a linear drive device, for example, corresponding to the drive on one side of the first gantry unit. The guide part of the second gantry unit may be formed, for example, in connection with the drive element, corresponding to the configuration possibilities given above for the first gantry unit. Further, the guide portion may be formed using a guide element formed separately from the drive element, for example, one or a plurality of guide rails and one or a plurality of guide carriages slidable along the guide rails. Good.

  The gantry arm guided on one side is in this case formed such that the gantry arm is guided to the first support in one end range and is not guided in the other range, in particular it projects freely. ing.

  The mounting head provided on the gantry arm guided on both sides or the gantry arm guided on one side is slidably arranged along each gantry arm, for example. The mounting head may in this case be formed as a single mounting head with one grip unit for picking up electrical and / or optical components. Such a gripper may be, for example, a pipette for adsorbing components by negative pressure, or alternatively a mechanical grip unit. Furthermore, it may be formed as a multi-mounting head provided with a number of gripper units. In this case, the gripper may be formed as previously described. In the case of a multi-loading head, these grippers may be mounted, for example, on a unit that is rotatably supported, in which case this unit may be mounted on, for example, a horizontal axis, a vertical axis or even an oblique It may be mounted so as to be rotatable about an axis (eg “revolver head” or “Turret-Head”). Further, in the case of multiple mounting heads, the grippers may be attached to the mounting heads in parallel with each other without a rotatable unit for the grippers (eg “matrix head”).

  In an advantageous configuration of the invention, the second gantry unit is, for example, movably attached to one second gantry arm guided on one side and to the second gantry arm. A mounting head for mounting the component on a substrate located in the mounting range, and one end range of the second gantry arm guided on one side is guided by the second support. It may be formed so that. The drive, guide and mounting head of the second gantry arm guided on one side can each be configured as described above in relation to the first gantry arm guided on one side and the gantry arm guided on both sides It may be formed according to the sex.

  By using such a second gantry arm guided on one side, the flexibility or flexibility of the automatic mounting device is further improved. Because when these gantry arms guided on one side are used, both supports are utilized and one gantry guided on both sides can be replaced with two gantry arms guided on one side Because. Both gantry arms guided on one side of the second gantry unit may in particular be able to move independently and independently of each other, thus allowing flexibility when mounting to one or more substrates present in the mounting range Can be further improved.

  In addition, the first and second gantry arms guided on one side of the second gantry unit can be moved alongside each other during the course of movement of the gantry arms guided by the respective supports. It may be formed as follows. In this way, it is possible to further increase the movement play space of both gantry arms guided on one side. This further increases the flexibility in mounting to one or more substrates present in the mounting range.

  In this case, the extension length of both gantry arms guided on one side is dimensioned so that they do not collide with each other when they pass each other within the normal operating mode of the automatic mounting device. Good. In this case, the mounting head support on the gantry arm guided on one side is either one of both mounting heads, even in the intermediate range between the areas covered by each gantry arm. It may be formed to be reachable by Mounting head support on a gantry arm guided on one side is further formed so that the gripper can move beyond the unguided or freely protruding end of the gantry arm guided on one side May have been. In this case, the mounting head must be pulled back accordingly in the above-mentioned “no collision” configuration of the gantry arm as both gantry arms guided on one side move alongside each other. Don't be.

  In a further advantageous configuration, the first support has a first guide rail and a first guide carriage slidable along the first guide rail, the second support. Has a second guide rail and a second guide carriage slidable along the second guide rail.

  In this case, the automatic mounting apparatus may be formed such that the first and second guide carriages can be detachably coupled to the gantry arms guided on both sides of the first gantry unit, respectively. This configuration has the advantage that the position adjustment process after replacement of the gantry arm or gantry unit can be reduced. The arrangement is such that the guide carriage is disengaged from the gantry arm, for example by screw connection or clamp connection, for exchanging one gantry arm guided on both sides, and the guide carriage is guided when the gantry unit is removed. Allows the gantry to be changed to stay on the rails. Adaptation of the guide carriage to the guide rail is particularly time consuming and is prone to errors and failures, so that such a configuration eliminates the need for a new position adjustment of the new guide carriage on the existing guide rail.

  Further, the first gantry arm guided on one side of the second gantry unit may be releasably connectable to the first guide carriage. Furthermore, the second gantry arm guided on one side of the second gantry unit may also be detachably connectable to the second guide carriage. Corresponding to the above case, in this configuration, the guide carriage of each gantry arm corresponds to one gantry arm guided on one side of the second gantry unit or both gantry arms guided on one side. You can stay on the guide rail. This further reduces or saves the effort required for a new position adjustment of the guide element after the gantry replacement.

  In that case, the recombination of the automatic mounting device from the first gantry unit having one gantry arm guided on both sides to the second gantry unit having two gantry arms guided on one side, for example, According to the configuration, for example, it can be implemented as follows: the guide carriage on the first guide rail provided on the first support is detached from one end of the gantry arm guided on both sides. The Thereafter, the second guide carriage on the second guide rail provided on the second support is detached from the other end of the gantry arm guided on both sides. Then, after the gantry arm guided on both sides is taken out, the guided end range of the first gantry arm guided on one side of the second gantry unit is placed on the guide carriage located on the first guide rail. The guided end area of the second gantry arm guided on one side of the second gantry unit is then coupled to the guide carriage on the second guide rail. That is, the guide carriage can remain on each corresponding guide rail during the exchange.

  Furthermore, the automatic mounting apparatus according to the above description may be formed such that each gantry arm is driven via a spindle driving apparatus. In this case, for example, a rotatable spindle may be coupled to each support, and this spindle engages (screws in) a drive carriage formed, for example, as a thread unit. The drive carriage is coupled to one gantry arm, for example, in a detachable manner.

  Furthermore, the drive of each gantry arm of a gantry unit can also be performed via a linear drive device. A linear drive usually consists of an active primary part, often one or more coils that are energized, and a passive secondary part, often one or more permanent magnets. For simplicity of the following description without limiting generality, the following specification and claims assume that the drive is a “moving coil” type linear drive. In the moving coil type linear drive device, the movable primary part has a coil to be energized, and the fixed fixed secondary part is formed as a permanent magnet rail (hereinafter referred to as “magnet rail”). The primary part (hereinafter referred to as “linear drive unit”) can move along the permanent magnet rail. However, the embodiment relating to the linear motor described below is directed to another linear driving device structure (for example, a “moving magnet” type structure having a fixed primary coil portion and a movable secondary permanent magnet portion). It can be conveniently diverted.

  In the case of a linear drive device, for example, the following embodiments can be considered. In other words, the first support body has the first magnet rail, and the second support body has the second magnet rail. In that case, one gantry arm guided on both sides of the first gantry unit is formed such that the gantry arm has one linear drive unit in one of the end ranges. It's okay. Furthermore, the gantry arm guided on both sides may be formed such that a linear drive unit is provided in the range of both ends of the gantry arm. The drive of the first gantry unit is in this case performed on both sides via the interaction of the linear drive unit and the first and second magnet rails. In that case, both linear drive units located in the end range of the gantry arm may be correlated such that the gantry arm is moved without distortion when driven on both sides of the gantry arm.

  The drive device for the gantry arm guided on one side of the second gantry unit may also be formed as a linear drive device. In that case, the drive is effected through the interaction of the first magnet rail with the linear drive unit attached to the guided end range of the gantry arm guided on one side.

  Even when the second gantry unit has two gantry arms guided on one side, the driving device for the first gantry arm guided on one side is a linear driving device as described above. It may be formed. In this case, the drive of the second gantry arm guided on one side of the second gantry unit was attached to the end range of the second gantry arm guided on one side, again as a linear drive device. This can be done through the interaction of the linear drive unit and the second magnet rail.

  The previously described embodiment of driving through a linear drive has the following advantages. In other words, the first and second magnet rails can be used both by the first gantry unit drive device and by the second gantry unit drive device. This allows for a simplified structure of the automatic mounting device.

Further, in the automatic mounting apparatus, a first interface for supplying a medium is arranged corresponding to the first support, and a second interface for supplying the medium is arranged corresponding to the second support. It may be formed as it is. In this case, the first and second interfaces for media supply are respectively
-For electrical energy supply to the gantry unit
-For supplying and / or deriving control signals to the gantry unit;
For the supply and / or derivation of the cooling medium to the gantry unit and / or for the pneumatic or hydraulic supply to the gantry unit
It may be formed.

  In the case of a gantry arm guided on both sides of the first gantry unit, is the medium supply to the first gantry unit performed, for example, via the first medium supply unit or the second medium supply unit? Alternatively, it can be performed via the first medium supply unit and the second medium supply unit. That is, for example, in the case of a single gantry arm guided on both sides, driven on one side of the first gantry unit, media supply on one side can take place via the first interface or the second interface. . In the case of a gantry arm guided on both sides, driven on both sides, of the first gantry unit, the media supply can be effected, for example, at least partially via both interfaces. That is, for example, the medium supply to the drive unit located on the first support of the first gantry unit is performed via the first interface, and the medium supply to the drive unit located on the second support is made to the second. This can be done through the interface. The media supply for the entire gantry unit and / or mounting head can be effected, for example, via either interface of both interfaces, or alternatively via both interfaces.

  The medium for the drive unit may belong to, for example, a current supply for the drive unit, a control signal for the drive unit, and a cooling medium for the drive unit. For example, a corresponding energy supply line, control line or also a cooling line may belong to the medium supply for the mounting head. For example, sensor information or position information, general control information, and identification information for a part of the gantry unit or the entire gantry unit may belong to the medium for the entire gantry unit.

  In the case of the second gantry unit with one gantry arm guided on one side, the medium supply to the gantry arm guided on the first support on one side is arranged corresponding to the first support. It can also be done via a first interface for media supply. In the case of a second gantry unit having two gantry arms guided on one side, the medium supply to the first gantry arm guided on the first support on one side is applied to the first support. This can be done via a correspondingly arranged first interface for media supply. In contrast, the medium supply to the second gantry arm guided on one side of the second gantry unit can be performed via an interface for medium supply arranged corresponding to the second support.

  The embodiments listed above have the following advantages. That is, the interface provided for supplying the medium can be used by both the first gantry unit and the second gantry unit. This allows for a simpler and cost saving construction of the automatic mounting device.

  The medium supply can be formed, for example, as a so-called cable carrier (Kabelschlepp), or also as a movable cable chute (Kabelschacht) or a movable cable guide. In this case, these medium supply units may be connected to each support, for example, or may be connected to the base unit in the vicinity of each support. In that case, when replacing the gantry unit, for example, the medium supply unit is dissociated from the cable carrier, for example, at the transition part to the end range of each gantry support. It can be connected to a connection provided on the gantry arm. Alternatively, each cable carrier or cable guide may be rigidly connected to the gantry unit and disconnected at the transition from the cable carrier or cable guide to the base unit when the gantry unit is replaced. .

  Furthermore, the first support may have a first motion control element and the second support may have a second motion control element. Such a control element may be formed, for example, to accurately detect movement of the gantry arm along each support. For example, such a control element may be formed as a scale attached to the support. In that case, for example, the motion control of the first gantry unit can be performed by the first motion control element and / or the second motion control element.

  In that case, a sensor element may be provided in the end range of the first gantry unit. By means of the sensor element, the movement of the gantry arm guided on both sides of the first gantry unit is monitored, for example, on a scale provided on the first support or the second support. In addition, monitoring using the sensor element can be performed by a scale provided on the first support or by a scale provided on the second support. For the movement control of one gantry arm guided on one side of the second gantry unit or the movement control of both gantry arms guided on one side of the second gantry unit, the same sensor is used as described above. Can be done. The sensor is mounted on each guided end region of a gantry arm guided on one side.

  In particular, a movement control element, for example a scale, provided for movement control on the first support and the second support is provided by the gantry arm of the first gantry unit and by the gantry arm of the second gantry unit. Are also advantageously used.

  Furthermore, the automatic mounting apparatus may have a third gantry unit. In this case, the third gantry unit includes one other gantry arm guided on both sides, and a mounting head for mounting the component on a substrate located in a mounting range, which is movably attached to the gantry arm. And each end region of the further gantry arm guided on both sides is guided and / or supported by the first support and the second support.

  The third gantry unit may be formed in accordance with the configurability mentioned above and below with respect to the first gantry unit. That is, the third gantry unit is movably coupled to the first support body and the second support body, and additionally improves the mounting possibility of the automatic mounting apparatus.

  Furthermore, the automatic mounting apparatus may have a fourth gantry unit. In this case, the fourth gantry unit includes one other gantry arm guided on one side, and a mounting head that is movably attached to the gantry arm and mounts the component on a substrate located in the mounting range. And one end range of another gantry arm guided on one side is guided to the first support. The further gantry arm guided on one side may be formed as described above or as described below, corresponding to the gantry arm guided on one side of the second gantry unit. . With the fourth gantry unit, the mounting flexibility and mounting output or mounting efficiency of the automatic mounting apparatus can be further improved.

  In particular, the automatic mounting apparatus has a third gantry unit or a fourth gantry unit, and the third gantry unit and the fourth gantry unit are interchangeable with each other. It is also conceivable that a gantry unit and a fourth gantry unit and an automatic mounting device are formed.

  Furthermore, the fourth gantry unit may be formed such that the fourth gantry unit has two gantry arms guided on one side. In this case, the first further gantry arm guided on one side has a second gantry arm guided on one side and the component on the substrate located on the mounting head movably attached to the gantry arm. A mounting head for mounting is added. In that case, one end range of the second another gantry arm guided on one side is guided by the second support. That is, the fourth gantry unit may have two gantry arms guided on one side, both gantry arms again corresponding to the configuration described herein for example with respect to the second gantry unit. And may be formed.

  The automatic mounting apparatus formed in this way has greater flexibility or flexibility when adapting to various mounting conditions. That is, the automatic mounting device can be operated using, for example, two gantry arms guided / supported on both sides. Furthermore, the automatic mounting device can be recombined as needed into one gantry arm guided / supported on both sides and one or two gantry arms guided on one side. Furthermore, even when the automatic mounting apparatus includes the second gantry unit and the fourth gantry unit, the automatic mounting apparatus may be equipped with two, three, or four gantry arms guided on one side, respectively. it can. In the first of the cases, for example, mounting with high accuracy and relatively high speed is possible, whereas the latter configuration allows for increased speed and adaptation to one or more substrates and It allows mounting with increased flexibility in terms of adapting to a variety of component parts.

  In order to guide the third gantry unit and / or the fourth gantry unit, another first guide carriage is attached to the first guide rail, and another second guide rail is attached to the second guide rail. A guide carriage may be attached. In that case, in order to guide the gantry arm guided on both sides of the third gantry unit, the first guide carriage and / or the second guide carriage is provided at each end of the gantry arm of the third gantry unit. It may be releasably bound to the range. The first further gantry arm guided on one side of the fourth gantry unit may further be releasably connectable to the further first guide carriage that travels along the first guide rail. . Correspondingly, a second further gantry arm guided on one side of the fourth gantry unit is also releasably coupled to the further second guide carriage running along the second further guide rail. It may be possible.

  The guides / supports of the third gantry unit and the fourth gantry unit are further guided / supported in accordance with the configuration possibilities of the first gantry unit or the second gantry unit mentioned in this specification. May have been.

  Further, the driving devices for the third gantry unit and the fourth gantry unit are formed in accordance with the driving means and configuration of the driving devices for the first gantry unit and the second gantry unit, which are also mentioned in this specification. It may be. That is, the third gantry unit can be driven, for example, on one or both sides, for example via a spindle drive or a linear drive. Similarly, the driving of one gantry arm guided on one side of the fourth gantry unit or the driving of both gantry arms guided on one side of the fourth gantry unit can be performed by, for example, the spindle driving device or the linear driving. This can be done via the device. In the case of the linear drive of the third gantry unit and / or the fourth gantry unit, the first magnet rail and the second magnet rail can be used correspondingly. In this case, each drive unit may be attached to the end range of the gantry arm of each gantry unit. In the case of a spindle drive device, for example, a dedicated spindle may be provided for each drive unit.

  The motion control of the third gantry unit and / or the fourth gantry unit may also be performed by the first motion control element and / or the second motion control element. Also in this case, the configuration of the third gantry unit or the fourth gantry unit is formed in accordance with the configuration described in the present specification with respect to the first gantry unit and / or the second gantry unit. Good. Again, it is conceivable that the third gantry unit or the fourth gantry unit uses the same movement control element, for example the same scale, as the first gantry unit and / or the second gantry unit.

  Furthermore, in order to facilitate replacement of the gantry unit, in yet another advantageous embodiment of the invention, the first support and the second support each have at least one replacement range; The first gantry unit, the second gantry unit, the third gantry unit and / or the fourth gantry unit are moved to the replacement range for replacement. This exchange range may be a range that is located on the first support and the second support, in particular configured to replace the gantry unit or to facilitate the replacement of the gantry unit.

  For example, in an automatic mounting apparatus having only a first gantry unit or a second gantry unit exchangeable with each other, it is conceivable that an exchange range is provided in the first support body and the second support body. Furthermore, in the automatic mounting apparatus having the first gantry unit or the second gantry unit exchangeable with each other and the third gantry unit or the fourth gantry unit exchangeable with each other, the first support members are respectively provided. It is conceivable that the second support is provided with two exchange ranges. In this case, one first replacement range for replacing the first gantry unit or the second gantry unit may be provided. Further, one second replacement range for replacing the third gantry unit or the fourth gantry unit may be provided. However, each support has only one replacement range for the replacement of the first gantry unit and the second gantry unit and for the replacement of the third gantry unit and the fourth gantry unit. Is also possible.

  In particular, when a linear drive device is used, it is conceivable that a part of the magnet rail can be removed and attached in the replacement range. That is, for example, before replacing the gantry unit, one or more magnet elements of the magnet rail located in the replacement range of the first support and the second support can be removed. Thereafter, the gantry unit can be moved to the replacement range. The gantry unit can then be removed more easily after all the corresponding other connections, for example the connection for media supply and / or the connection for guiding or supporting the gantry arm, are disengaged. be able to. This is because, in that case, the strong magnetic force generated by the linear drive device is significantly reduced. After a new gantry unit is brought into the exchange area and a corresponding connection, for example a connection to the media connection or guide element, is formed, the new gantry unit can be advanced again from the exchange area. Then, after the magnet element is newly incorporated in the replacement range, the automatic mounting apparatus can use the entire movement range of the magnetic drive device again. In this way, for example, a simple replacement of the gantry unit can be achieved without losing athletic play and space in the automatic mounting device.

  In the case of a gantry unit equipped with a spindle drive device, this spindle drive device may be formed as follows, for example. That is, the drive spindle arranged corresponding to the support is slidably arranged, in which case the spindle is no longer engaged with the corresponding corresponding member provided in the gantry unit in the exchange range for exchanging the gantry unit. It will not match. Accordingly, the gantry unit moved to the exchange range or the gantry unit moved at least partly manually to the exchange range can then be removed without interference by the drive spindle.

  In another configuration of the automatic mounting device, at least one of the previously mentioned gantry arms or at least one of the gantry units may each have one electronic storage unit. In this case, in the electronic storage unit of one gantry arm or one gantry unit, information regarding the configuration or arrangement of the gantry arm or the gantry unit is stored or can be stored. The fact that one gantry arm has one electronic storage unit similarly means that one electronic storage unit is arranged corresponding to the gantry arm and is connected to the gantry arm. Or it includes moving synchronously with the gantry arm.

In this case, the information regarding the configuration or arrangement of one gantry arm or the configuration or arrangement of one gantry unit is:
The identification symbol or identification code of the gantry arm or the gantry unit,
Information on the number and / or position of the guide elements of the gantry arm or the gantry unit,
-Information about the geometry of the gantry arm or the gantry unit,
-Information about one or more mounting heads located in the gantry arm or the gantry unit;
Information on one or more optical sensors coupled to the gantry arm or the gantry unit and / or the geometry measured relative to each other of the individual components of the gantry arm measured externally Information on the (geometric) position (eg calibration data) and / or the geometric position of the individual components of the gantry arm relative to a given point.

  Thus, for example, after replacing one gantry unit with another gantry unit, data about the arrangement of the gantry unit, ie how many gantry arms the gantry unit consists of, for example Which mounting head is attached to the gantry unit, which camera is provided, calibration data of the gantry arm, mounting head or camera, and a unique gantry arm or gantry unit Data such as an identification symbol or an identification code can be automatically transmitted to the control unit of the automatic mounting apparatus. Thereafter, the autoloader can directly control the new gantry unit that has been replaced and can operate without the need for, for example, a basic calibration operation or laborious manual input.

  In this way, the recombination time when replacing the gantry unit can be significantly reduced. This is because the number of manual inputs by the operator is reduced or even completely eliminated. The time for calibration can also be reduced. In some circumstances, post-calibration can be completely eliminated using the configuration data of a newly used gantry arm or a new gantry unit.

The subject is further a pick and place automatic mounting system for mounting electrical and / or optical components to a substrate,
A base unit is provided, said base unit being formed as described above, i.e. first and second supports extending longitudinally and aligned substantially parallel; A mounting range for supplying at least one substrate on which the electrical and / or optical components to be mounted are located between the first and second supports,
A first gantry unit is provided, the first gantry unit being formed as described above, ie one gantry arm guided on both sides and movably attached to the gantry arm A mounting head for mounting the component on a substrate positioned in the mounting range, and each end range of the gantry arm guided on both sides is a first and second support body. And / or supported by
A second gantry unit is provided, the second gantry unit being formed as described above, ie one gantry arm guided on one side and movably attached to the gantry arm A mounting head for mounting the component on the substrate located in the mounting range, and one end range of the gantry arm guided on the one side is guided by the first support. In the form of
-Solved by an automatic mounting system for mounting electrical and / or optical components on a substrate, characterized in that the first and second gantry units are interchangeable.

  Such an automatic mounting system can be flexibly adapted to the requirements imposed on the automatic mounting device, for example in terms of accuracy, flexibility or flexibility and speed, as explained above.

  Further, the automatic mounting system may include a third gantry unit having the above-described configuration and a fourth gantry unit having the previously described configuration. It is advantageous if the four gantry units are interchangeable. That is, the automatic mounting system has a third gantry unit, and the third gantry unit is mounted on one gantry arm guided on both sides and movably attached to the gantry arm. A mounting head for mounting the component on a substrate located in a range, and each end range of another gantry arm guided on both sides is guided to the first and second supports. And / or is supported and the automatic mounting system has a fourth gantry unit, the fourth gantry unit being moved to one gantry arm guided on one side and to the gantry arm A mounting head for mounting the component on a board located in the mounting range, and is attached to the one end of another gantry arm guided on the one side Circumference are guided to the first support, a third gantry unit and a fourth gantry units are interchangeable.

  In the embodiment described above, the flexibility or flexibility of the automatic mounting system is further increased. This is because such an automatic mounting system has four gantry arms guided on one side from a single gantry arm with one gantry arm guided on one side or one gantry arm guided on both sides. This is because even up to four gantry systems can be freely adapted to the respective accuracy, flexibility and speed requirements. Further, the entire automatic mounting system may also be formed based on the configuration of the automatic mounting apparatus described above.

Similarly, the above-mentioned problem is that, in the method for recombining the automatic mounting device based on the configuration described above, the automatic mounting device includes the first gantry unit or the third gantry unit, and Step:
a) moving the first gantry unit or the third gantry unit to the exchange range provided on the first and second supports,
b) disconnecting the media connection between the first or third gantry unit and the media interface of the base unit;
c) disengaging the connection or coupling between the guide elements of the first and second supports and the gantry arms guided on both sides of the first or third gantry unit;
d) Remove the first or third gantry unit, install the second or fourth gantry unit into the replacement range,
e) a plurality of guide elements of the first and second supports, each of one of the gantry arms guided on one side of the second gantry unit or each of the gantry arms guided on one side of the fourth gantry unit; Each fixed to one position,
f) forming a media connection between each one gantry arm of the second or fourth gantry unit and each media interface of the base unit;
It is also solved by a method for recombining an automatic mounting device characterized in that it comprises a step comprising:

Further, the above-described problem is that in the method for recombining the automatic mounting apparatus according to the above description, the automatic mounting apparatus includes the second gantry unit or the fourth gantry unit, and in this case, according to the above description, respectively. The reverse steps are performed sequentially in the reverse order, ie the following steps:
a) moving the second gantry unit or the fourth gantry unit to the exchange range of the first and second supports,
b) dissociating the media connection between the second or fourth gantry unit and the media interface of the base unit;
c) dissociating the connection between the guide elements of the first and second supports and the gantry arm guided on one side of the second or fourth gantry unit;
d) Remove the second or fourth gantry unit, install the first or third gantry unit into the replacement range,
e) fixing the plurality of guide elements of the first and second supports to gantry arms guided on both sides of the first gantry unit or the third gantry unit;
f) forming a media connection between the first or third gantry unit and the media interface of the base unit;
It is also solved by a method for recombining an automatic mounting device characterized in that it comprises a step comprising:

  In the above method, each gantry unit is driven via a linear drive device, and before moving the gantry unit to be replaced to the replacement range, the first magnet rail of the first support member is moved inside the replacement range. The magnet element may be formed so as to be taken out from the second magnet rail of the second support. Furthermore, the method may be implemented such that after inserting a new gantry and moving the new gantry out of the exchange range, the corresponding magnet element is again inserted into each magnet rail.

Furthermore, the above-described problem is a pick-and-place type automatic mounting apparatus for mounting electrical and / or optical components on a board,
A base unit is provided, the base unit being provided for supplying a longitudinally extending support and at least one substrate on which electrical and / or optical components are to be mounted And has a range,
A gantry unit is provided, and the gantry unit is mounted on the board located in the mounting range, which is movably attached to the gantry arm and mounted on the board located in the mounting range. And one end range of the gantry arm is guided by the support,
A gantry unit is detachably formed, the support has an exchange range, into which the gantry unit is movable or can be moved for removal; This is solved by an automatic mounting device for mounting electrical and / or optical components on a substrate.

  In this case, the exchange range is, for example, that the section of the drive mechanism for the gantry unit that is coupled to the support and / or the section of the guide element for the gantry unit that is coupled to the support It may be reversibly changeable for removal or may be configured to change.

  The use of such an exchange range allows a simplified adaptation of the automatic mounting device to different requirements. That is, for example a section of a drive mechanism or guide for a gantry unit coupled to the support, eg a part of a magnet rail for a linear drive or a drive spindle for a spindle drive, It may be configured for the most optimal drive of the gantry unit over the required movement range in the working state. Then, in a second state, the exchange state, the section of the drive mechanism or guide part is simplified or generally made possible for removal of the gantry unit, for example by removal of the magnet element or movement of the drive spindle. It may be changed as follows.

  A “reversible change” within the frame of the present specification means that the user of the automatic mounting apparatus can be restored to the original state only by taking an acceptable effort, for example, mechanical, electrical, or Means any electromechanical change. Any kind of mechanical recombination, for example removal of a part (component) or movement of a part is a “change” within the frame of the above description. Changes can be made, for example, electrically controlled and automated. Further, the change may be, for example, a purely electrical property, and may be, for example, a change in energization to a part of the drive unit and / or a part of the gantry guide part.

  The gantry arm of the gantry unit may not be guided, for example, in the second end region, but may be formed in a particularly freely projecting manner, ie in a cantilevered manner.

  The support may further be formed as a first support as described above, for example. Furthermore, the automatic mounting device may further comprise a second support, which is substantially parallel to the first support. In that case, the gantry unit may be formed of, for example, a first gantry unit, a second gantry unit, a third gantry unit, or a fourth gantry unit as described above. The gantry arm can also be guided, for example, only on one side and supported on the other side, unguided or freely protruding. Furthermore, the gantry arm may be guided on both sides.

  The automatic mounting device may further be formed by all the corresponding configurability mentioned in the above description for various improvements of the automatic mounting device.

  In the following, embodiments of the invention will be described in detail with reference to the drawings.

  FIG. 1 shows a pick-and-place type automatic mounting apparatus 100 including one base unit 110 and two support blocks 120 and 130. One guide rail 124, 134 for guiding a gantry attached to the automatic mounting apparatus 100 is fixed to the support blocks 120, 130, respectively. Furthermore, one magnet rail 122, 132 is attached to the support block 120, 130, respectively. The magnet rails 122 and 132 are used to drive the gantry of the automatic mounting apparatus 100.

  The automatic mounting apparatus 100 has a first gantry sub-unit 140. This first gantry sub-unit 140 is shown in the left part of the automatic mounting apparatus 100 as seen in FIG. The first gantry sub-unit 140 (hereinafter also referred to as “first stub gantry 140”) has a mounting head 146 that picks up, transports and places down the component 199. A suction pipette 147 is provided. The first stub gantry (Stummelportal) 140, which is a short gantry having a short arm shape, is driven through a linear motor drive unit 143. The linear motor drive unit 143 is attached to the gantry head 142 of the first stub gantry 140 and interacts with the left magnet rail 122 as seen in the drawing. The gantry head 142 is coupled to the guide carriage 126 via, for example, a screw coupling or a clamp coupling, so that the guide carriage 126 accurately guides the first stub gantry 140 during movement along the support block 120. Is called.

  The first stub gantry 140 further includes a gantry arm 144. The mounting head 146 can move along the gantry arm 144. In the right part of FIG. 1, a second gantry sub-unit 150 (hereinafter also referred to as “second stub gantry 150”) is illustrated. The second gantry sub-unit 150 includes a gantry arm 154 and a mounting head 156 that can move along the gantry arm 154. The mounting head 156 has a vacuum gripper 157, which is formed as a suction pipette 157, and is formed to pick up, convey and place down a component 199 to be mounted. The second stub gantry 150, which is a short gantry with a short arm shape, is guided through the guide carriage 136. The guide carriage 136 is coupled to the gantry head 152 of the second stub gantry 150 through screw coupling or clamp coupling. The second stub gantry 150 is driven via a linear motor drive unit 153 coupled to the gantry head 152. The linear motor drive unit 153 interacts with the right magnet rail 132 as seen in the drawing.

  FIG. 1 further shows a printed wiring board transport mechanism 190 for transporting the printed wiring boards 180 and 182. In the arrangement shown in FIG. 1, the first printed wiring board 180 is positioned below the mounting head 146 of the first stub gantry 140, and the second printed wiring board 182 is the second stub gantry 150. It is located below the mounting head 156. Both printed wiring boards 180 and 182 already have some electronic components 199 mounted thereon. In this case, not all of the electronic components shown in FIG. 1 are shown for the sake of clarity.

  Both first and second stub gantry 140, 150 form two sub-units of one gantry unit with two gantry guided on each side as previously described. That is, the gantry unit described above is formed by the first and second stub gantry 140 and 150 together in this case.

  In this case, the mounting range 189 is a range in which the electronic components can be picked up, that is, picked up, put down, or placed down, for the suction pipettes 147 and 157. The mounting heads 146, 156 and the gantry arms 144, 154 may be configured such that each suction pipette 147, 157 can be moved to a position slightly beyond the end of each gantry arm 144, 154. With such a configuration, an overlap range can be formed at the center of the mounting range 189 shown in FIG. In this overlap range, electronic components can be picked up and / or placed down by the mounting head 146 of the first stub gantry 140 and by the mounting head 156 of the second stub gantry 150.

  FIG. 2 shows a top view of the pick-and-place type automatic mounting apparatus 100 shown in FIG. Corresponding units have the same symbols. FIG. 2 further illustrates supply ranges 196 and 198. In these supply ranges 196 and 198, electronic components to be mounted are supplied. The supply ranges 196, 198 may have, for example, a supply unit (“belt feeder”) for supplying electronic components with component belts. Furthermore, the supply ranges 196, 198 are for example component supply units consisting of, for example, a flat magazine, or alternatively “Wafer-Feeder” for supplying semiconductor wafers which are applied to a sheet and sliced, for example. May be included. The mounting range 189 extends partially over the supply range 196,198. This is because the mounting head must enter at least this range in order to pick up the electronic components.

  Further illustrated in FIG. 2 is a first replacement range 123 in the magnet rail 122 along the first support block 120. In the first exchange range 123 provided on the magnet rail 122, for example, the magnet element can be taken out from the magnet rail 122 before the first stub gantry 140 is removed. The corresponding magnet element can later be reinserted, so that the entire travel range of the magnet rail 122 can be utilized after the insertion of another gantry unit. The magnet rail 132 of the second support block 130 also has an exchange range 133. In the second exchange range 133, the magnet element can be taken out from the magnet rail 132 in the same manner as described above.

  Next, a disassembled example of a gantry unit composed of a first stub gantry 140 and a second stub gantry 150 will be described with reference to FIGS. First, the magnet elements are taken out from the magnet rails 122 and 132 in the replacement ranges 123 and 133. Next, the stub gantry 140, 150 is moved to each exchange range or pushed. The gantry heads 142, 152 are then disengaged from the corresponding guide carriages 126, 136, respectively, with the stub gantry 140, 150 located in the exchange range 123, 133 (eg, screw and / or clamp coupling). By dissociation).

  Thereafter, the stub gantry 140, 150 can be easily lifted. This is because only a small magnetic force is exerted by removing the magnet element in the exchange ranges 123 and 133. In this case, the guide carriages 126, 136 remain on the corresponding guide rails 124, 134. Prior to lifting, the media connection between the automatic loading apparatus 100 and the stub gantry 140, 150 is disengaged. These media connections are used, for example, for current supply, signal supply and / or signal delivery or pneumatic supply to the gantry subunit. Such a medium connection is not shown in FIGS. 1 and 2 for the sake of clarity.

  FIG. 3 shows another configuration of the automatic mounting apparatus 100 shown in FIGS. 1 and 2, in which the automatic mounting apparatus 100 is an alternative one gantry unit guided on both sides. 160. The gantry unit 160 has one gantry arm 164 and a mounting head 166 movably attached to the gantry arm 164, and the mounting head 166 includes a suction gripper 167. On the one hand, the gantry arm 164 is guided via a guide carriage 126 guided by a guide rail 124 to the first support block 120. The guide carriage 126 is coupled to the gantry head 162 on the left side of the gantry unit 160 as viewed in the drawing by, for example, screw coupling or clamp coupling. Further, the gantry arm 164 is guided on the other side by a guide carriage 136, which can move along the guide rail 134 and is coupled to the gantry head 168 on the right side of the gantry unit 160. (Eg via screw connection or clamp connection).

  The gantry unit 160 is driven by the magnet rails 122 and 132 on both sides. The magnet rails 122 and 132 are attached to both support blocks 120 and 130 of the automatic mounting apparatus 100. For driving, the gantry arm 160 has a linear motor drive unit 163 on the left side in the drawing. The linear motor drive unit 163 is fixed to the left gantry head 162. Further, the gantry unit 160 has a linear motor drive unit 169 on the right side in the drawing, and this linear motor drive unit 169 is attached to the right gantry head 168. By these two drive units, the synchronized driving of both sides of the gantry arm 164 is performed. This gantry arm 164 allows for relatively quick and very accurate positioning of the mounting head 166.

  In order to remove or attach the gantry unit 160 guided on both sides, for example, a process similar to that in the embodiment described above can be performed. In this case, the removal is prepared, for example, by removing the magnet element in the exchange range 133,123. Next, in order to take out the gantry unit 160 guided on both sides, the gantry unit 160 is moved to the replacement range, and the guide carriages 126 and 136 are disengaged from the gantry heads 162 and 168 of the gantry unit 160 guided on both sides. And then the gantry is lifted. For mounting, for example, the reverse process can be performed accordingly.

  FIG. 4 shows an alternative embodiment alternative to the embodiment shown in FIG. In this embodiment, a gantry unit 170 guided / supported on both sides is shown. The gantry unit 170 also has one gantry arm 174, and a mounting head 176 having a suction gripper 177 is slidably supported on the gantry arm 174. As in the embodiment shown in FIG. 3, the gantry unit 170 is driven on both sides, the left linear motor drive unit 173 attached to the left gantry head 172 as viewed in the drawing, and the right side as viewed in the drawing. This is performed via a linear motor drive unit 179 attached to the gantry head 178.

  Unlike the embodiment shown in FIG. 3, in the embodiment shown in FIG. 4, the gantry arm 174 is guided only on one side and is simply supported on the other side (by the mounting portion). ). The right gantry head 178 is coupled to a guide carriage 136 that travels along the guide rail 134 of the right support block 130 for (one side) guidance. On the left side in the figure, the gantry arm 174 is supported by the sliding bearing 171. The sliding bearing 171 travels along the guide rail 124. Such a mounting portion not only allows movement along the guide rail, but also allows movement in a direction perpendicular to the guide rail (eg, parallel to the longitudinal axis of the gantry arm). To do.

  Alternatively, the placing portion may be formed by a traveling roller or an air bearing, for example. Such a mounting portion, for example, cooperates with the illustrated linear drive device to change the length of the gantry arm 174 within a certain range, for example, thermal expansion or contraction of the gantry arm 174 of the gantry unit 170, for example. enable. This can reduce, for example, distortion and wear phenomena that occur during operation.

  In order to lift or mount the gantry unit 170, a process corresponding to the embodiment shown in the previous drawings is performed. In this case, the mounting unit 171 is additionally assembled / removed depending on circumstances. There must be.

  FIG. 5 shows a top view of the embodiment shown in FIG. The reference numerals used in FIG. 5 correspond to those used in the preceding drawings.

  FIG. 6 shows another embodiment of the automatic mounting apparatus 200. This automatic mounting apparatus 200 includes, for example, a gantry unit 260 guided on both sides as shown in FIG. 3 or FIG. 5 and two stub gantry 240 and 250 as shown in FIG. 1 and FIG. The reference numerals used in FIG. 6 correspond to the reference numerals used in FIG. 1 to FIG. 5, but in this case, the reference numerals in the 100s of the reference numerals used in FIG. 1 to FIG. This corresponds to the code of the turntable.

  Unlike the embodiment described above, the automatic mounting apparatus 200 shown in FIG. 6 has a so-called dual type (double type) printed wiring board conveyance mechanism. This dual-type printed wiring board transport mechanism includes four guide rails 290, which are arranged side by side for printed wiring boards 280, 281, 282, and 283 on which electronic components are to be mounted. Two positioned tracks are formed. The electronic components 299 to be mounted are supplied through supply ranges 296 and 298 located on the side of the automatic mounting apparatus 200. These supply ranges 296 and 298 may be formed in the same manner as the supply ranges 196 and 198 in the above embodiment.

  The first gantry unit 260 has one gantry arm 264 and a mounting head 266 that can move along the gantry arm 264. The gantry arm 264 is guided through the guide carriages 227 and 237. These guide carriages 227 and 237 are detachably coupled to the gantry heads 262 and 268 of the gantry unit 260, respectively, and are movable along the guide rails 234 and 224. The gantry is driven through linear motor drive units 263 and 269 attached to the respective gantry heads 262 and 268 and magnet rails 232 and 222.

  Further, the automatic mounting apparatus 200 has a second gantry unit, and the second gantry unit includes two stub gantry 240 and 250. Both stub gantry 240 and 250 have one gantry arm 244 and 254, respectively, and one mounting head 256 and 246 can move along this gantry arm 244 and 254, respectively. The two stub gantry 240 and 250 are guided via (one each) guide carriages 226 and 236. The guide carriages 226 and 236 are detachably coupled to the gantry heads 252 and 242 of the stub gantry 240 and 250, respectively. In this case, the guide carriages 226 and 236 are guided along the guide rails 234 and 224, respectively. The The stub gantry 240, 250 is driven via one linear motor drive unit 243, 253, respectively. These linear motor drive units 243 and 253 are also attached to the gantry heads 242 and 252 of the stub gantry 240 and 250 to enable movement of the stub gantry 240 and 250 along the corresponding magnet rails 232 and 222. To do.

  The automatic mounting apparatus 200 further has two replacement ranges 225, 235, 223, and 233. In this case, the first exchange ranges 225 and 235 of the magnet rails 222 and 232 are provided for exchanging the gantry unit 260 guided on both sides. In this exchange range 225, 235, the magnet element can be taken out from the magnet rails 222, 232 in order to facilitate the removal of the gantry unit 260. The process for removing and attaching the gantry unit 260 may correspond to, for example, the process described with reference to FIG. 3 or FIG. Further, the automatic mounting apparatus 200 has second replacement ranges 223 and 233. The second exchange ranges 223 and 233 are formed in the same manner as the exchange ranges 123 and 133 shown in FIGS. In order to replace the second gantry unit consisting of both stub gantry 240, 250, both stub gantry 240, 250 are moved to the correspondingly prepared replacement range 223, 233, for example by removal of the magnet part. For example, as described with reference to FIGS. 1 and 2.

  FIG. 7 illustrates various improvements and adaptability of the automatic mounting apparatus 200 shown in FIG.

  FIG. 7 a shows an automatic mounting apparatus 200 with support blocks 220, 230. The first gantry unit 260 can move along the support blocks 220 and 230. The first gantry unit 260 has one gantry arm 264, two gantry heads 262 and 268, and one mounting head 266 guided by the gantry arm 264. Electronic components are supplied from supply ranges 296 and 298. The refinement shown in FIG. 7a is suitable, for example, for high precision mounting of a large number of electronic components. This is because the gantry unit 260 guided on both sides has high accuracy and can approach both supply ranges 296 and 298.

  In an improved version of the automatic mounting device 200 shown in FIG. 7b, a second gantry comprising two short gantry units, ie stub gantry 240, 250, each guided only on one side. It is replaced by the unit. In this case, the first stub gantry 240 has one gantry arm 244, a mounting head 246 guided by the gantry arm 244, and a gantry head 242. The first stub gantry 240 is guided to the support block 220 by the gantry head 242. The second stub gantry 250 also has one gantry arm 254, a mounting head 256 guided by the gantry arm 254, and a gantry head 252, and the second stub gantry 250 is supported by the gantry head 252. It is guided to the body block 230. Since both the first and second stub gantry 240, 250 are cantilevered, the other end of each of the stub gantry 240, 250 is formed so as to protrude freely. The parts can move through each other when driving. The other symbols used in FIG. 7b correspond to those in FIG. 7a or FIG.

  Also in the following FIGS. 7c, 7d and 7e, the same reference numerals are used for the same units, so the reference numerals in FIGS. 6 and 7a to 7e correspond to each other.

  An improved version of the automatic mounting apparatus 200 shown in FIG. 7b has an increased mounting output compared to the automatic mounting apparatus 200 shown in FIG. 7a. This is because the stub gantry 240, 250 can be mounted in parallel and substantially independently of each other. In this case, high component diversity remains guaranteed. This is because both stub gantry 240 and 250 can approach both supply ranges 296 and 298. The accuracy of the improved version shown in FIG. 7b is generally lower than that of the improved version shown in FIG. 7a. This is because the stub gantry is based on one-sided guidance and has low accuracy at the time of wearing if the motion parameters (for example, moving speed and acceleration) are the same.

  In FIG. 7c, a third improvement of the automatic mounting device 200 is shown. In this case, the automatic mounting apparatus 200 has the gantry unit 260 guided on both sides already shown in FIG. 7a and another gantry unit 310 guided on both sides. The gantry unit 310 may be formed corresponding to the first gantry unit 260 guided on both sides. An improved version of the automatic mounting device 200 shown in FIG. 7c, which also has two mounting heads, has a lower component diversity and a higher accuracy than the embodiment of FIG. 7b. This is because the gantry units 260, 310 guided on both sides can only approach one supply range each, but generally allow more accurate positioning of each mounting head.

  FIG. 7d shows an improved version of the automatic mounting apparatus 200 as already shown, for example, in FIG. The automatic mounting apparatus 200 shown in FIG. 7d has a higher mounting output than the improved version shown in FIG. 7c. This is because the second gantry unit 310 guided on both sides shown in FIG. 7c is replaced by two short gantry units, ie, stub gantry 240 and 250. This provides one more mounting head for mounting. However, mounting using the two stub gantry 240, 250 can usually be performed with lower accuracy than mounting performed using the second gantry unit 310 guided on both sides.

  In FIG. 7e, the first gantry unit 260 guided on both sides is also replaced by another gantry unit with two stub gantry 320, 330 with respect to the improvement shown in FIG. 7d. This variation of the automatic mounting device 200 has a maximum mounting output. This is because the four mounting heads can mount electronic components separately and independently of each other on one or more substrates located in the mounting range. On the other hand, the two stub gantry can only approach one of the supply ranges 296, 298 respectively, so that the component diversity is particularly reduced compared to the improvement shown in FIG. 7a or 7d. Yes.

  The configuration illustrated in FIGS. 6 and 7 of the automatic mounting apparatus 200 achieves a very wide range of variability in adapting the automatic mounting apparatus 200 to various mounting conditions.

  In particular, an additional variable configuration of the printed wiring board transport mechanism that enables both single-track and multi-track transport of one or several types of printed wiring boards is set from the outside. A wide range of adaptability of the automatic mounting device to conditions such as accuracy requirements, number of printed wiring boards to be mounted in parallel, required mounting speed, diversity of components and / or positioning accuracy or mounting accuracy in various configurations Sex is obtained.
