Description

The techniques disclosed herein relate to component mounting machines.

Various proposals have been made to save space in the component mounting machine. For example, in the component mounting machine disclosed in Patent Document 1, a plurality of substrates are collectively conveyed by pushing a plurality of substrates arranged along the substrate conveying direction from the rear. As a result, during the transfer of the substrates, the substrates are not separated from each other, and the mutual positional relationship between the substrates is maintained. Therefore, it is not necessary to provide a dedicated jig for maintaining the mutual positional relationship between the substrates, the cost can be reduced, and the space can be saved.

In the technical field of component mounting machines, in general, when producing different types of substrates, it is necessary to move or replace the units installed in the component mounting machine. For example, it is necessary to adjust the width of the conveyor that conveys the substrate according to the dimensions of the substrate to be produced, or to replace the nozzle according to the type of electronic component to be mounted. Conventionally, a relatively large unit such as a conveyor or a nozzle holder for accommodating a nozzle (in other words, a unit whose installation position is fixed during mounting work and is not arranged between a pair of conveyors. Hereinafter, in the present specification, The in-flight unit) was moved or replaced by an operator or a dedicated drive mechanism. For this reason, there is a problem that a space for an operator to access and a space for installing the drive mechanism are required, and the device becomes large. The present specification provides a technique capable of moving an in-flight unit while suppressing an increase in the size of the device.

The component mounting machine disclosed in the present specification mounts electronic components on a substrate. The component mounting machine includes one or a plurality of in-machine units, a movable unit, and a control unit. The one or more in-flight units are fixed in the installation position during the mounting work of the electronic component on the board, and are not arranged between the pair of conveyors that convey the board. The movable portion is separate from the in-flight unit, can move relative to the in-flight unit, and includes a moving mechanism for moving the in-flight unit from the installation position. The control unit is a control unit that controls the movement of the movable portion and the operation of the moving mechanism, and moves the in-flight unit from the installation position by moving the movable portion and operating the moving mechanism. Let me.

In addition, in this specification, "not arranged between a pair of conveyors" means that the area inside the component mounting machine is sandwiched between the pair of conveyors when the pair of conveyors and the in-machine unit are viewed in a plan view. It means that the in-flight unit is not located. Therefore, in the present specification, the "pair of conveyors" is included in the "in-flight unit".

In the above-mentioned component mounting machine, the control unit moves a movable portion that is separate from the in-machine unit, so that the moving mechanism provided in the movable portion is moved together. Then, the control unit operates the moving mechanism to move the in-flight unit from the installation position. As described above, in the above-mentioned component mounting machine, since the mechanism for moving the in-machine unit (that is, the movable part) is provided separately from the in-machine unit, the movable part can be used for other purposes. .. That is, in the above-mentioned component mounting machine, manual work or a dedicated drive mechanism is not required to move the in-machine unit, and it is possible to suppress the increase in size of the device.

The figure which shows typically the structure of the unit movement mechanism of Example 2. The figure which shows an example of the structure of the nozzle holder of Example 2. The figure which shows the state which the in-flight unit is handed over between the attached component mounting machines.

In one embodiment of the present technology, the movable portion may be a head to which a nozzle for sucking the electronic component can be attached and detached.

In such a configuration, the mechanism for moving the head can be used in combination for mounting the electronic component using the nozzle and moving the in-flight unit.

In one embodiment of the present technology, the in-flight unit may be the pair of conveyors. At least one of the pair of conveyors may be movable in a direction perpendicular to the transport direction of the substrate when viewed in a plan view. The control unit may bring the moving mechanism into contact with at least one of the conveyors and move the head to change the width of the pair of conveyors.

In such a configuration, the width of the pair of conveyors can be changed by using a mechanism for moving the head. Therefore, when switching from the production of one type of substrate to the production of a type of substrate having different dimensions, the width of the conveyor can be adapted to the dimensions of the substrate.

In one embodiment of the present technology, the component mounting machine may further include a locking mechanism that limits the movement of at least one of the conveyors. The moving mechanism may be switchable between a standby state in which the pair of conveyors cannot be contacted and an operating state in which the pair of conveyors can be contacted. The lock mechanism may release the restriction on the movement of at least one of the conveyors when the moving mechanism is switched from the standby state to the operating state.

In such a configuration, the locking mechanism restricts the movement of the conveyor while the moving mechanism is in the standby state. Therefore, it is possible to suppress unintended movement of the conveyor (movement in a direction perpendicular to the transport direction in a plan view).

In one embodiment of the present technology, the pair of conveyors may be provided with alignment marks for positioning the pair of conveyors. The head may include a camera that captures the alignment mark. The control unit may adjust the width of the pair of conveyors by moving the head based on the position of the alignment mark imaged by the camera.

In such a configuration, the width of the conveyor is adjusted based on the position of the alignment mark, so that the width of the conveyor can be controlled more accurately.

In one embodiment of the present technology, the in-flight unit includes a nozzle holder that accommodates the nozzle and transfers the nozzle to and from the head, a parts camera that captures the electronic component adsorbed on the nozzle, and a parts camera. It may be at least one of the parts disposal boxes. The control unit may move the in-flight unit together with the head by moving the head while the in-flight unit is supported by the moving mechanism.

In such a configuration, it is possible to realize a relatively large in-flight unit such as a nozzle holder, a parts camera, and a parts disposal box, which was difficult in the past, by using a mechanism for moving the head. Therefore, it is possible to suppress the increase in size of the device without the need for manual work for moving the in-flight unit or a dedicated drive mechanism.

In one embodiment of the present technology, the component mounting machine may further include an in-flight unit accommodating portion for accommodating the in-flight unit. The control unit accommodates the in-flight unit installed at the installation position in the in-flight unit accommodating unit by the moving mechanism, and installs a new in-flight unit accommodated in the in-flight unit accommodating unit at the installation position. You may.

With such a configuration, the in-flight unit can be automatically replaced when it becomes necessary to replace the in-flight unit.

In one embodiment of the present technology, the in-flight unit may include a fitting portion that can be fitted with the moving mechanism. The in-flight unit may be supported by fitting the moving mechanism to the fitting portion.

In such a configuration, the in-flight unit can be supported and moved by the head with a simple configuration.

In one embodiment of the present technology, the head may include a camera for imaging the in-flight unit. The control unit may position the moving mechanism with respect to the in-flight unit by moving the head based on the position of the in-flight unit imaged by the camera.

In such a configuration, the position of the head (that is, the position of the moving mechanism with respect to the in-flight unit) is adjusted based on the position of the in-flight unit imaged, so that the moving mechanism can access the in-flight unit more accurately. Can be done.

(Example 1)
Hereinafter, the component mounting machine 10 of the first embodiment will be described with reference to the drawings. The component mounting machine 10 is a device for mounting the electronic component 4 on the substrate 2. The component mounting machine 10 is called a surface mounting machine or a chip mounter. Usually, the component mounting machine 10 is installed side by side with other board working machines such as a solder printing machine and a board inspection machine to form a series of mounting lines.

As shown in FIGS. 1 and 2, the component mounting machine 10 includes a component feeder 12, a feeder holding unit 14, a head 16, a head moving mechanism 19, a transport device 20, and a lock mechanism 21 (see FIG. 5). The imaging unit 22, the parts camera 23, the nozzle accommodating unit 24, the nozzle holder 26, the parts disposal box 28, the touch panel 30, and the control unit 32 are provided.

Each component feeder 12 accommodates a plurality of electronic components 4. The component feeder 12 is detachably attached to the feeder holding portion 14, and supplies the electronic component 4 to the head 16. The specific configuration of the component feeder 12 is not particularly limited, and for example, a tape-type feeder that accommodates a plurality of electronic components 4 on a winding tape, a tray-type feeder that accommodates a plurality of electronic components 4 on a tray, or a container. It may be any of bulk feeders that randomly accommodate a plurality of electronic components 4 therein.

The feeder holding portion 14 has a plurality of slots, and the component feeder 12 is detachably installed in each of the plurality of slots. The feeder holding portion 14 may be fixed to the component mounting machine 10 or may be detachable from the component mounting machine 10.

The head 16 is configured so that a nozzle 6 for sucking an electronic component 4 can be attached and detached. The head 16 is fixed to the moving base 17. The head 16 includes an actuator (not shown) for moving the mounted nozzle 6 in the Z direction (that is, in the vertical direction), and causes the nozzle 6 to move closer to and away from the component feeder 12 and the substrate 2. For example, the head 16 can attract the electronic component 4 from the component feeder 12 by the nozzle 6 and mount the electronic component 4 attracted to the nozzle 6 on the substrate 2. The head 16 is not limited to a configuration in which a single nozzle 6 can be attached and detached, and a plurality of nozzles 6 may be attached and detached.

The head moving mechanism 19 is a robot that moves the moving base 17 in the X direction and the Y direction (that is, the horizontal direction). The head moving mechanism 19 is composed of a guide rail for guiding the moving base 17, an actuator for moving the moving base 17 along the guide rail, and the like. The head moving mechanism 19 is arranged above the component feeder 12 and the transport device 20.

The transport device 20 carries in, supports, and carries out the substrate 2. The transport device 20 transports the substrate 2 in the X direction. In this embodiment, the transfer device 20 is attached to a pair of conveyors 20a and 20b, a transfer device 20, a support device (not shown) that supports the substrate 2 from below, and an actuator that drives the transfer device 20 (not shown). It is composed of a rail (shown) and a rail 20c (see FIGS. 3 and 4). The conveyor 20a is provided on the feeder holding portion 14 side. The conveyor 20b is provided on the side opposite to the feeder holding portion 14 with respect to the conveyor 20a. The conveyor 20b is configured to be movable in a direction perpendicular to the transport direction of the substrate (that is, in the Y direction) with respect to the conveyor 20a when viewed in a plan view. Specifically, as shown in FIG. 3, a rail 20c is provided below the conveyor 20b, and the conveyor 20b is configured to be movable on the rail 20c. That is, the width between the conveyors 20a and 20b becomes variable by moving the conveyor 20b guided by the rail 20c with respect to the conveyor 20a. As a result, the transport device 20 can transport the substrate 2 having various types of dimensions. Further, the transport device 20 is provided with an alignment mark 50. The position where the alignment mark 50 is provided is not particularly limited, and may be provided within a range that can be imaged by the camera 22b described later (for example, the upper surface of the conveyor 20b).

As shown in FIGS. 3 and 4, the lock mechanism 21 is attached to the conveyor 20b. The lock mechanism 21 is an actuator for limiting the movement of the conveyor 20b in the Y direction. The lock mechanism 21 is in a locked state (state shown in FIG. 3) that abuts (engages) with the rail 20c to restrict the movement of the conveyor 20b, and an unlocked state that allows the conveyor 20b to move away from the rail 20c. It is configured to be switchable to (the state shown in FIG. 4). The configuration of the lock mechanism 21 is not limited to the above, and any configuration may be used as long as it can be switched to a state in which the movement of the conveyor 20b with respect to the rail 20c is restricted and permitted.

As shown in FIGS. 5 and 6, the head 16 includes a conveyor moving mechanism 18. The conveyor moving mechanism 18 is used to move the conveyor 20b from the installation position, and by moving the conveyor 20b in the Y direction, the widths of the pair of conveyors 20a and 20b are changed. In this embodiment, the conveyor moving mechanism 18 is composed of an air cylinder. The conveyor moving mechanism 18 switches between a standby state in which the piston rod 18b is housed in the cylinder 18a (state shown in FIG. 5) and an operating state in which the piston rod 18b protrudes from the cylinder 18a (state shown in FIG. 6). It is configured to be possible. The control unit 32 controls the supply of air to the conveyor moving mechanism 18, so that the air cylinder is switched between the standby state and the operating state.

The image pickup unit 22 is attached to the moving base 17. Therefore, when the head 16 moves, the imaging unit 22 also moves together. The image pickup unit 22 includes a camera support portion 22a and a camera 22b. The camera 22b is arranged on the side of the head 16. The camera 22b is arranged so that the imaging optical axis faces downward. In this embodiment, the camera 22b images the alignment mark 50 provided on the conveyor 20b.

The parts camera 23 is arranged between the parts feeder 12 and the transfer device 20. The parts camera 23 is arranged so that the imaging optical axis faces upward. The parts camera 23 takes an image of the lower surface of the electronic component 4 attracted to the nozzle 6. As a result, the control unit 32 can grasp the posture of the electronic component 4 attracted to the nozzle 6.

The nozzle accommodating portion 24 is arranged between the component feeder 12 and the conveying device 20. The nozzle accommodating unit 24 can accommodate a plurality of nozzles 6, and transfers the nozzles 6 to and from the head 16. Specifically, each nozzle 6 is housed in a nozzle holder 26 attached to the nozzle housing unit 24. A plurality of types of nozzles 6 can be accommodated in the nozzle holder 26. The nozzle holder 26 is removable from the nozzle accommodating portion 24, and is removed from the nozzle accommodating portion 24, for example, when the nozzle 6 in the nozzle holder 26 is replaced.

The component disposal box 28 (hereinafter referred to as the disposal box 28) is arranged between the component feeder 12 and the transfer device 20. When an abnormality occurs in the electronic component 4 supplied from the component feeder 12, the electronic component 4 (for example, a defective product) having the abnormality is discarded in the disposal box 28. When the nozzle 6 attracts the abnormal electronic component 4, the control unit 32 positions the head 16 above the waste box 28 by the head moving mechanism 19. Then, the nozzle 6 is lowered toward the disposal box 28 to stop the suction of the electronic component 4. As a result, the electronic component 4 falls from the nozzle 6 and is discarded in the disposal box 28.

The touch panel 30 is a display device that provides various information to the operator, and is a user interface that receives instructions and information from the operator.

The control unit 32 is composed of a computer including a CPU, a ROM, and a RAM. The control unit 32 includes each component feeder 12, a feeder holding unit 14, a head 16, a moving base 17, a conveyor moving mechanism 18, a transport device 20, a lock mechanism 21, an imaging unit 22, a parts camera 23, a nozzle accommodating unit 24, and a nozzle holder. It is communicably connected to 26, the disposal box 28, and the touch panel 30. The control unit 32 executes a process of changing the widths of the pair of conveyors 20a and 20b (hereinafter, referred to as a width changing process) by controlling each of the above units.

Subsequently, the width changing process of the conveyors 20a and 20b will be described in more detail. In the technical field of component mounting machines, when the type of substrate to be produced changes, it is necessary to adjust the widths of the conveyors 20a and 20b according to the dimensions of the substrate. In this embodiment, when the type of substrate to be produced changes, the control unit 32 switches the conveyor moving mechanism 18 from the standby state to the operating state, and releases the restriction on the movement of the conveyor 20b by the lock mechanism 21. That is, the control unit 32 makes the piston rod 18b protrude from the cylinder 18a and makes the conveyor 20b movable.

Next, as shown in FIG. 7, the control unit 32 brings the piston rod 18b into contact with the conveyor 20b by moving the head 16. Then, with the piston rod 18b in contact with the conveyor 20b, the head 16 is moved in the Y direction as shown by the arrow 200. As a result, the conveyor 20b is pushed by the piston rod 18b, and the conveyor 20b moves on the rail 20c in the direction indicated by the arrow 210. At this time, the control unit 32 adjusts the position of the conveyor 20b based on the captured image of the camera 22b. That is, the control unit 32 sets the conveyor 20b from the Y coordinate (position in the Y direction) of the head 16 when the alignment mark 50 is imaged and the Y coordinate (position in the Y direction) of the alignment mark 50 in the captured image. The widths of the conveyors 20a and 20b are adjusted by calculating the Y coordinate (position in the Y direction) of the above and driving the head 16 so that the position of the conveyor 20b becomes a desired position.

When the movement of the conveyor 20b is completed, the control unit 32 switches the conveyor moving mechanism 18 from the operating state to the standby state, and switches the locking mechanism 21 to the locked state to limit the movement of the conveyor 20b. By executing the above processing, the widths of the conveyors 20a and 20b are changed.

As described above, in this embodiment, the width between the pair of conveyors 20a and 20b can be changed by using the mechanism for moving the head 16. Therefore, when switching from the production of one type of substrate to the production of a type of substrate having different dimensions, the widths of the conveyors 20a and 20b can be adapted to the dimensions of the substrate. Therefore, it is not necessary to separately provide a dedicated drive mechanism for changing the widths of the conveyors 20a and 20b, and it is possible to suppress an increase in the size of the apparatus.

Further, conventionally, after changing the widths of the conveyors 20a and 20b using a dedicated drive mechanism, it is confirmed whether or not the conveyor 20b is positioned at the position by the camera 22b provided on the head 16. Therefore, there is a problem that the working time becomes long. However, in this embodiment, the detection of the alignment mark 50 and the positioning of the conveyor 20b can be executed in parallel by using the head 16. Therefore, the working time can be shortened as compared with the conventional case.

In the above-described embodiment, the conveyor moving mechanism 18 is provided on the head 16, but the conveyor moving mechanism 18 may be attached to another movable element.

In the first embodiment described above, the conveyor moving mechanism 18 was composed of an air cylinder. However, the configuration of the conveyor moving mechanism 18 is not particularly limited as long as it can come into contact with the conveyor 20b when the head 16 is moved.

The head 16 is an example of a “movable part”. The conveyor moving mechanism 18 is an example of the “moving mechanism”. The camera 22b is an example of a “camera”.

(Example 2)
Next, the component mounting machine 100 of the second embodiment will be described. Hereinafter, a configuration different from that of the first embodiment will be described, and the description of the same configuration as that of the first embodiment will be omitted. As shown in FIG. 8, the component mounting machine 100 includes a unit moving mechanism 118 instead of the conveyor moving mechanism 18 of the first embodiment. Further, the component mounting machine 100 includes an in-machine unit accommodating unit 110.

The in-flight unit accommodating portion 110 is arranged on the touch panel 30 side of the component mounting machine 100. That is, the in-flight unit accommodating unit 110 is arranged at a position that is easily accessible to the operator. The in-flight unit accommodating unit 110 accommodates spare in-flight units (parts camera 23, nozzle holder 26, disposal box 28).

The unit moving mechanism 118 is a member for moving the parts camera 23, the nozzle holder 26, and the disposal box 28 from the installation position. As shown in FIG. 9, in the present embodiment, the unit moving mechanism 118 has a shaft portion 118a and a plurality of support pieces 118b provided in the circumferential direction at the lower end portion of the shaft portion 118a. The unit moving mechanism 118 is configured to be rotatable around the shaft portion 118a.

In this embodiment, the control unit 32 moves the in-flight unit (parts camera 23, nozzle holder 26, disposal box 28) from the installation position by controlling each unit described in the first embodiment and the unit moving mechanism 118. .. Hereinafter, as an example of moving the in-flight unit, a case where the nozzle holder 26 is moved from the installation position will be described.

As shown in FIG. 10, the nozzle holder 26 is provided with a fitting portion 26a. The opening of the fitting portion 26a has substantially the same shape as the projected shape of the shaft portion 118a and the support piece 118b when the unit moving mechanism 118 is viewed in a plan view. The opening of the fitting portion 26a when viewed in a plan view has a slightly larger area than the projected shape. That is, the shaft portion 118a and the support piece 118b can pass through the opening of the fitting portion 26a.

When moving the nozzle holder 26 from the installation position, first, the nozzle holder 26 is imaged by the camera 22b. As a result, the exact position of the nozzle holder 26 is detected. Then, the control unit 32 positions the unit moving mechanism 118 above the fitting portion 26a (that is, a position where the unit moving mechanism 118 can pass through the opening of the fitting portion 26a) by moving the head 16. Next, the control unit 32 lowers the head 16 toward the nozzle holder 26 and inserts the support piece 118b into the fitting unit 26a. The control unit 32 rotates the unit moving mechanism 118 around the shaft portion 118a with the support piece 118b inserted into the fitting portion 26a. As a result, the support piece 118b can come into contact with the inner surface of the fitting portion 26a to support the nozzle holder 26. After that, the control unit 32 can lift the nozzle holder 26 by the unit moving mechanism 118 by raising the head 16 and move the head 16 to move the nozzle holder 26 to a desired position.

In the process of producing the substrate, it may be necessary to replace the nozzle 6 to be used. In such a case, it is necessary to replace the currently mounted nozzle holder 26 with a nozzle holder 26 containing the nozzle 6 to be used. At that time, the currently mounted nozzle holder 26 is moved to the in-flight unit accommodating portion 110 by the method described above. Then, a new nozzle holder (that is, the nozzle holder 26 in which the nozzle 6 used for the next production is housed) previously stored in the in-flight unit housing unit 110 is lifted and moved by the same method, and the nozzle housing unit 24 is moved. Install in. As a result, the nozzle holder 26 can be replaced automatically.

As described above, in the present embodiment, the mechanism for moving the head 16 can be used to realize a relatively large movement of the in-flight unit, which has been difficult in the past. Therefore, it is possible to suppress the increase in size of the device without the need for manual work or a dedicated drive mechanism for moving the in-flight unit from the installation position.

When moving the parts camera 23 and the disposal box 28 from the installation position, the parts camera 23 and the disposal box 28 may be provided with a fitting portion similar to the fitting portion 26a of the nozzle holder 26. As a result, the parts camera 23 and the disposal box 28 can be moved from the installation position by using the head 16.

Further, in the above-described embodiment, the in-flight unit is moved from the installation position by supporting the in-flight unit by the support piece 118b. However, the configuration of the unit moving mechanism 118 for moving the in-flight unit is not particularly limited. For example, the unit moving mechanism 118 may be configured to attract the in-flight unit by magnetic force, or may be configured to attract the in-flight unit by negative pressure (suction).

Further, the position for moving the in-machine unit is not limited to the inside of the component mounting machine 100. For example, as shown in FIG. 11, in two side-by-side component mounting machines 100, an in-machine unit (for example, a nozzle holder 26) may be handed over from one component mounting machine 100 to the other component mounting machine 100. In this case, the in-flight unit may be provided with at least two fitting portions.

In the above-described embodiment, the unit moving mechanism 118 is provided on the head 16, but the unit moving mechanism 118 may be attached to another movable element.
