DETAILED DESCRIPTION OF THE INVENTION

[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings as modes for carrying out the present invention.

[0009] 1 shows a component mounter 10. The component mounter 10 is a device for performing the operation of mounting components on a circuit substrate 12. The component mounter 10 includes a device main body 20, a substrate transport and holding device 22, a component mounting device 24, a mark camera 26, a parts camera 28, a bulk component supply device 30, a component supply device 32, and a control device (see FIG. 3) 36. Examples of the circuit substrate 12 include a circuit board and a substrate with a three-dimensional structure, and examples of the circuit substrate include a printed wiring board and a printed circuit board.

[0010] The device main body 20 is composed of a frame 40 and a beam 42 suspended from the frame 40. The substrate transport and holding device 22 is disposed in the center of the frame 40 in the front-to-rear direction and includes a transport device 50 and a clamping device 52. The transport device 50 transports the circuit substrate 12, and the clamping device 52 holds the circuit substrate 12. As a result, the substrate transport and holding device 22 transports the circuit substrate 12 and securely holds the circuit substrate 12 at a predetermined position. In the following description, the transport direction of the circuit substrate 12 is referred to as the X direction, the horizontal direction perpendicular to that direction is referred to as the Y direction, and the vertical direction is referred to as the Z direction. In other words, the width direction of the component mounter 10 is the X direction, and the front-to-rear direction is the Y direction.

[0011] The component mounting device 24 is mounted on the beam 42 and includes two work heads 60, 62 and a work head moving device 64. Each work head 60, 62 has a suction nozzle 66 (see FIG. 2) that holds a component. As shown in FIG. 2, the work head moving device 64 includes an X-direction moving device 68, a Y-direction moving device 70, and a Z-direction moving device 72. The X-direction moving device 68 and the Y-direction moving device 70 move the two work heads 60, 62 together to any position on the frame 40. Each work head 60, 62 is detachably attached to a slider 74, 76, and the Z-direction moving device 72 moves the slider 74, 76 individually in the vertical direction. That is, the work heads 60, 62 are moved individually in the vertical direction by the Z-direction moving device 72.

[0012] As shown in Fig. 2, mark camera 26 is attached to slider 74 facing downward, and is moved in the X, Y, and Z directions together with work head 60. This allows mark camera 26 to capture an image of any position on frame 40. Also, part camera 28 is disposed on frame 40 between substrate material conveying and holding device 22 and component supply device 32 facing upward, as shown in Fig. 1. This allows part camera 28 to capture an image of a component held by suction nozzle 66 of work heads 60, 62.

[0013] The bulk parts supplying device 30 is disposed on one side surface in the front-to-rear direction of the main body 20. The bulk parts supplying device 30 is detachably connected to one side surface in the front-to-rear direction of the main body 20. The bulk parts supplying device 30 is a device that aligns multiple parts that are scattered randomly and supplies the aligned parts. In other words, it is a device that aligns multiple parts in any orientation into a predetermined orientation and supplies the aligned parts.

[0014] The component supply device 32 is disposed on the other side surface in the front-rear direction of the apparatus main body 20. The component supply device 32 is detachably connected to the other side surface in the front-rear direction of the apparatus main body 20. The component supply device 32 has a feeder-type component supply device 86 and a tray-type component supply device 88. The feeder-type component supply device 86 is a device that supplies components by a tape feeder 90. The tray-type component supply device 88 is a device that supplies components that are placed on a tray (not shown).

[0015] As shown in FIG. 3, the control device 36 includes a controller 100, multiple drive circuits 102, and an image processing device 104. The multiple drive circuits 102 are connected to the conveying device 50, the clamping device 52, the work heads 60 and 62, the work head moving device 64, the feeder-type component supply device 86, the tray-type component supply device 88, and the bulk component supply device 30. The controller 100 is a computer-based device equipped with a CPU, ROM, RAM, etc., and is connected to the multiple drive circuits 102. This allows the controller 100 to control the operation of the substrate conveying and holding device 22, the component mounting device 24, etc. The controller 100 is also connected to the image processing device 104. The image processing device 104 processes image data obtained by the mark camera 26 and the part camera 28, and the controller 100 acquires various information from the image data.

[0016] With the above-described configuration, the component mounter 10 performs a component mounting operation on the circuit board 12 held by the substrate conveying and holding device 22. Specifically, the circuit board 12 is carried into a predetermined work position by the conveying device 50 and fixedly held at that position by the clamping device 52. Next, the mark camera 26 moves above the circuit board 12 and captures an image of the circuit board 12. This provides information regarding an error in the holding position of the circuit board 12. Furthermore, the bulk component supply device 30 or the component supply device 32 supplies a component at a predetermined supply position. Then, one of the work heads 60, 62 moves above the component supply position and holds the component with the suction nozzle 66. Next, the work head 60, 62 holding the component moves above the part camera 28, and the part camera 28 captures an image of the component held by the suction nozzle 66. This provides information regarding an error in the holding position of the component. Then, the work heads 60, 62 holding the components move above the circuit board 12, and the components they are holding are mounted on the circuit board 12 after correcting any errors in the holding position of the circuit board 12, errors in the holding position of the components, etc.

[0017] In this manner, the component mounter 10 performs the mounting operation of components on the circuit board 12. Furthermore, as shown in FIG. 4 , the component mounter 10 is provided with a display device 110 on one side surface in the front-to-rear direction, i.e., the Y direction, of the device body 20, and a display panel (not shown) of the display device 110 displays information corresponding to the mounting operation performed by the component mounter 10. This allows an operator to monitor the mounting operation performed by the component mounter 10 by visually checking the display panel. Furthermore, the display device 110 is provided with a plurality of operation switches (not shown), and the operator controls the operation of the component mounter 10 by operating each operation switch. Therefore, to ensure the visibility of the display panel and the operability of the operation switches, it is necessary to secure space in front of the display device 110. Furthermore, a bulk component supply device 30a is detachably connected to one side surface of the device body 20 on which the display device 110 is provided. However, to prevent the display device 110 and the bulk component supply device 30a from overlapping on one side of the device main body 20 on which the display device 110 is disposed, the width dimension of the bulk component supply device 30a is made smaller than the width dimension of the device main body 20 minus the width dimension of the display device 110. By making the width dimension of the bulk component supply device 30a smaller in this way, the visibility of the display panel of the display device 110 and the operability of the operation switches are ensured when the bulk component supply device is connected to one side of the device main body.

[0018] However, reducing the width of the bulk component supply device 30a may reduce the volume of the bulk component supply device 30a, potentially reducing the amount of components supplied by the bulk component supply device 30a. Therefore, to increase the amount of components supplied, it may be possible to adopt a bulk component supply device 30b wider than the bulk component supply device 30a, as shown in FIG. 5 . For example, it may be possible to adopt a bulk component supply device 30b with a width equal to the width of the device main body 20. However, adopting the bulk component supply device 30b would not ensure satisfactory visibility of the display panel of the display device 110 or operability of the operation switches. Even if satisfactory visibility of the display panel and operability of the operation switches could be ensured by some method, a dead space 116 equivalent to the thickness of the display device 110 would be created between the device main body 20 and the bulk component supply device 30b, causing the bulk component supply device 30b to extend forward in the Y direction. This increases the installation area of ​​the component mounter 10, causing problems with the installation space of the component mounter 10 and making it difficult for workers to access the display device 110. In addition, since the supply position of components by the bulk component supply device 30b is separated from the device main body 20, there is also the problem of an increase in the cycle time when supplying components.

[0019] In consideration of this, the component mounter 10 employs a display device 120 (see FIG. 6) that is arranged to be movable between a display position located on one side of the device main body 20 to which the bulk component supply device 30b is connected and a retracted position retracted from the display position. FIG. 6 shows the display device 120 positioned at the display position. The display device 120 can be moved between the display position and the retracted position on the device main body 20 by a pair of first hinges 126 and a pair of second hinges 128.

[0020] 7, the display device 120 includes a generally rectangular parallelepiped display device main body 130, a display panel 132 disposed on the front surface of the display device main body 130, and a plurality of operation switches 134 disposed below the display panel 132. The display device 120 is fixed to the device main body 20 via a pair of first hinges 126 and a pair of second hinges 128, with the display panel 132 and the plurality of operation switches 134 exposed on the front side. The first hinge 126 is composed of a pair of blades 140, 142 and a pin 146 that swingably connects the pair of blades 140, 142 to each other. The second hinge 128 is composed of a pair of blades 150, 152 and a pin 156 that swingably connects the pair of blades 150, 152 to each other.

[0021] The pair of first hinges 126 are arranged side by side in the X direction, and one of the pair of blades 140, 142 of each first hinge 126 is fixed to an upper end of one side surface 158 of the device body 20 with the pin 146 of each first hinge 126 extending in the X direction. The other of the pair of blades 140, 142 of each first hinge 126 is fixed to a connecting plate 160. Note that the connecting plate 160 is in close contact with the upper end surface of the display device 120 when the display device 120 is in the display position, but the connecting plate 160 and the display device 120 are not fixed to each other. The pair of second hinges 128 are arranged side by side in the X direction on the front side of the pair of first hinges 126. One of the pair of blades 150, 152 of each second hinge 128 is fixed to the connecting plate 160, with the pin 156 of each second hinge 128 extending in the X direction. The other of the pair of blades 150, 152 of each second hinge 128 is fixed to the upper end surface of the display device main body 130.

[0022] In this way, the display device 120 is fixed to the device main body 20 via the first hinge 126 and the second hinge 128, and thereby the display device 120 moves between the display position and the retracted position. More specifically, as shown in Fig. 8, when the first hinge 126 and the second hinge 128 are open, that is, when the pair of blades 140, 142 of the first hinge 126 are spaced apart and positioned on a straight line, and the pair of blades 150, 152 of the second hinge 128 are also spaced apart and positioned on a straight line, the rear surface of the display device 120 is in close contact with one side surface 158 of the device main body 20. Therefore, the display panel 132 and the operation switches 134 of the display device 120 are oriented to face forward, and the display device 120 is positioned in the display position, which is in front of one side surface 158 of the device main body 20.

[0023] 9, when the display device 120 positioned at the display position is lifted upward, the display device 120 rotates approximately 180 degrees around the pin 146 of the first hinge 126, and the first hinge 126 closes, that is, the pair of blades 140, 142 of the first hinge 126 move closer to each other. Note that a stopper 144 is provided on the upper surface of the blade 140 of the first hinge 126, and the approach of the pair of blades 140, 142 is restricted by the stopper 144. Therefore, the rotation of the display device 120 is restricted by the stopper 144.

[0024] Then, after the rotation of the display device 120 about the pin 146 of the first hinge 126 is restricted by the stopper 144, when the display device 120 is urged backward, as shown in FIG. 10 , the display device 120 rotates another 90 degrees about the pin 156 of the second hinge 128, and the second hinge 128 closes, that is, the pair of blades 150, 152 of the second hinge 128 move closer to each other. Then, the display device 120 comes into contact with the top surface of the device main body 20, thereby restricting the rotation of the display device 120 about the pin 156 of the second hinge 128. This causes the display device 120 to move to the retracted position. That is, after the display device 120 rotates from the display position about the pin 146 of the first hinge 126, it rotates about the pin 156 of the second hinge 128 to move to the retracted position. 10 shows the display device 120 just before it has rotated about the pin 156 of the second hinge 128 and is about to come into contact with the top surface of the device body 20. As shown in FIG.

[0025] In this way, the display device 120 is movable between the display position and the retracted position. When components are supplied by the narrow bulk component supply device 30a described above in the component mounter 10, the bulk component supply device 30a is connected to the device main body 20 with the display device 120 located at the display position. When the display device 120 is located at the display position, the display panel 132 and the operation switches 134 face forward, as shown in FIG. 8 . When the narrow bulk component supply device 30a is connected to the device main body 20 with the display device 120 located at the display position, the front side of the display device 120 is not blocked by the narrow bulk component supply device 30a, as shown in FIG. 4 . Therefore, when the narrow bulk component supply device 30a is connected to the device main body 20, the visibility of the display panel 132 of the display device 120 and the operability of the operation switches 134 are ensured.

[0026] On the other hand, when components are supplied by the wide bulk component supply device 30b described above in the component mounter 10, the bulk component supply device 30b is connected to the device main body 20 with the display device 120 in the retracted position, as shown in FIG. 11 . That is, the bulk component supply device 30b is connected to the device main body 20 after the display device 120 is moved from the display position to the retracted position. In this way, by connecting the bulk component supply device 30b to the device main body 20 after the display device 120 is retracted from one side surface 158 of the device main body 20, damage to the display device is prevented and dead space between the device main body 20 and the bulk component supply device 30b can be eliminated. This makes it possible to prevent an increase in the installation area of ​​the component mounter 10 and an increase in the cycle time during component supply.

[0027] However, when the display device 120 is positioned in the retraction device, as shown in Fig. 10, the display panel 132 and the operation switch 134 face the upper surface of the device main body 20, so the operator cannot see the display panel 132 or operate the operation switch 134. In consideration of this, a display device 180 is provided on the side of the bulk component supply device 30b opposite to the side connected to the device main body 20. The display device 180 has a display panel 182, and the same image as that displayed on the display panel 132 of the display device 120 is displayed on the display panel 182.

[0028] More specifically, when the bulk component supplying device 30b is not connected to the device main body 20, the controller 100 of the component mounter 10 outputs image data of a display image to the display device 120. As a result, an arbitrary display image is displayed on the display panel 132 of the display device 120. On the other hand, when the bulk component supplying device 30b is connected to the device main body 20, the bulk component supplying device 30b and the controller 100 are electrically connected. Therefore, when the bulk component supplying device 30b is connected to the device main body 20, the controller 100 of the component mounter 10 outputs image data of a display image not only to the display device 120 but also to the display device 180 of the bulk component supplying device 30b. As a result, the display panel 182 of the display device 180 provided in the bulk component supplying device 30b displays the exact same image as the image displayed on the display panel 132 of the display device 120 provided in the device main body. In other words, when the bulk component supplying device 30b is connected to the device main body 20, the display device 180 provided on the bulk component supplying device 30b displays the exact same image as the image displayed on the display device 120 provided on the device main body.

[0029] When the bulk component supply device 30b is connected to the device main body 20, the display panel 132 of the display device 120 located in the retracted position faces upward. Therefore, the worker cannot see the image displayed on the display panel 132 of the display device 120. In consideration of these factors, it is preferable that the display panel 132 of the display device 120 located in the retracted position does not display an image. That is, it is preferable that the display panel 132 displays an image when the display device 120 is located in the display position and does not display an image when the display device 120 is located in the retracted position. However, switching the display panel 132 between displaying and hiding an image depending on the position of the display device 120 is cumbersome in terms of control. Therefore, an image is displayed on the display panel 132 of the display device 120 regardless of the position of the display device 120, that is, whether the display device is located in the display position or the retracted position.

[0030] The display panel 132 of the display device 120 included in the apparatus main body and the display panel 182 of the display device 180 included in the bulk component supply device 30b connected to the apparatus main body 20 display, for example, the images shown in FIGS. 12 to 16 are displayed. Specifically, the image shown in FIG. 12 is an image for selecting the device to be maintained, such as the work heads 60 and 62 or the work head moving device 64. The image shown in FIG. 13 is an image for setting a mounting operation. The image shown in FIG. 14 is an image for selecting a production program for executing the mounting operation. The image shown in FIG. 15 is an image for setting the mark camera 26 or the parts camera 28. The image shown in FIG. 16 is an image for notifying an error.

[0031] As described above, the bulk component supplying device 30b is coupled to the main body 20 after the display device 120 of the main body 20 is moved from the display position to the retracted position. That is, the bulk component supplying device 30b should be coupled to the main body 20 after the display device 120 is retracted from the front side of the side surface 158 of the main body 20. However, when an operator manually moves the display device 120, there is a risk that the operator may forget to move the display device 120 from the display position and accidentally couple the bulk component supplying device 30b to the main body 20. Even if the operator moves the display device 120 from the display position, there is a risk that the operator may accidentally couple the bulk component supplying device 30b to the main body 20 before moving it to the retracted position, for example, when the display device 120 is not in the display position but is positioned in front of the side surface 158 of the main body 20. In such a case, interference between the bulk component supplying device 30b and the display device 120 may result in damage to at least one of the bulk component supplying device 30b and the display device 120.

[0032] In consideration of such a case, the display device 120 is provided with a movement mechanism 170 (see FIGS. 7 and 17), and the movement mechanism 170 is activated in conjunction with the operation of connecting the bulk component supply device 30b to the device main body 20, thereby automatically moving the display device 120 from the display position to the retracted position. More specifically, as shown in FIG. 17, the movement mechanism 170 has torsion springs 148, 159. The torsion spring 148 is wound around the pin 146 of the first hinge 126, and exerts an elastic force in a direction that closes the pair of blades 140, 142, that is, in a direction that brings the pair of blades 140, 142 closer to each other. On the other hand, torsion spring 159 is wound around pin 156 of second hinge 128 and exerts an elastic force in the direction of closing pair of blades 150, 152, that is, in the direction of bringing pair of blades 150, 152 closer to each other. Therefore, display device 120 is biased toward the retracted position by the elastic forces of torsion springs 148, 159. In other words, display device 120 is positioned in the retracted position by the elastic forces of torsion springs 148, 159 unless an external force is applied.

[0033] 7, the movement mechanism 170 includes a locking mechanism 172 and a release handle 174. The locking mechanism 172 is a mechanism for locking the display device 120 in the display position, and various structures can be used as long as the mechanism is capable of locking the display device 120 in the display position and releasing this lock. For example, a hooking portion is provided on the back surface of the display device 120, and a hooked portion for hooking the hooking portion is provided on one side surface 158 of the device body 20. Then, when the hooking portion of the display device 120 is hooked onto the hooked portion of the device body 20, the display device 120 is locked in the display position against the elastic force of the torsion springs 148, 159.

[0034] The release handle 174 is generally U-shaped and is disposed below the multiple operation switches 134 of the display device 120. Both ends of the generally U-shaped release handle 174 are inserted into the display device main body 130 of the display device 120 and are slidably held by the display device main body 130. The release handle 174 is biased in a direction away from the display device main body 130 by the elastic force of an elastic body (not shown). However, the extension amount of the release handle 174 from the display device main body 130 is restricted by a stopper (not shown). When the release handle 174 is pushed toward the display device main body 130, both ends of the release handle 174 advance toward the interior of the display device main body 130 against the elastic force of the elastic body. At this time, both ends of the release handle 174 come into contact with the locking mechanism 172, thereby releasing the display device 120 from the display position. Specifically, for example, the display device 120 is unlocked from the display position when both ends of the release handle 174 come into contact with latched portions of the device main body 20. As shown in Fig. 8, the release handle 174 extends furthest from the display device main body 130 among the members arranged on the display device main body 130, such as the operation switch 134.

[0035] With this structure, the moving mechanism 170 is activated in conjunction with the operation of connecting the bulk component supplying device 30b to the apparatus main body 20, and the display device 120 automatically moves from the display position to the retracted position. That is, when the display device 120 is locked at the display position by the locking mechanism 172, if the worker brings the bulk component supplying device 30b closer to the apparatus main body 20 to connect the bulk component supplying device 30b to the apparatus main body 20, the bulk component supplying device 30b first comes into contact with the release handle 174 of the display device 120. Then, when the worker brings the bulk component supplying device 30b even closer to the apparatus main body 20, the release handle 174 is pushed toward the display device main body 130 by the bulk component supplying device 30b, thereby releasing the lock of the display device 120 at the display position by the locking mechanism 172. Therefore, the elastic force of the torsion springs 148, 159 causes the display device 120 to move from the display position to the retracted position. Then, when the worker moves the bulk component supplying device 30b closer to the apparatus main body 20, the bulk component supplying device 30b is connected to the apparatus main body 20. In this manner, the movement mechanism 170 is actuated in conjunction with the connection of the bulk component supplying device 30b to the apparatus main body 20, and the display device 120 automatically moves from the display position to the retracted position. In other words, the display device 120 automatically moves from the display position to the retracted position in conjunction with the connection of the bulk component supplying device 30b to the apparatus main body 20, and then the bulk component supplying device 30b is connected to the apparatus main body 20. This reliably prevents interference between the bulk component supplying device 30b and the display device 120 during the connection of the bulk component supplying device 30b to the apparatus main body 20. Note that, before the connection of the bulk component supplying device 30b to the apparatus main body 20, the worker may push the release handle 174 toward the display device main body 130 to move the display device 120 from the display position to the retracted position. Furthermore, when moving the display device 120 from the retracted position to the display position, the operator must move the display device from the retracted position to the display position against the elastic forces of the torsion springs 148 and 159.

[0036] 18, in addition to the above-mentioned display device 120, another display device 190 is also provided on the device main body 20 of the component mounter 10. The display device 120 is provided on one side surface 158 of the device main body 20 to which the bulk component supply device 30 is connected, while the display device 190 is provided on another side surface 191 of the device main body 20 to which the component supply device 32 is connected. The display device 190 has substantially the same structure as the display device 120, and includes a display panel 192 and a plurality of operation switches 194. However, since the device main body 20 and the component supply device 32 are connected without interfering with each other, the display device 190 is not provided movably like the display device 120, but is fixedly provided on the device main body 20.

[0037] The component mounter 10 is an example of a work machine. The device main body 20 is an example of a work machine main body. The bulk component supply device 30 is an example of a connecting device. The display device 120 is an example of a first display device. The movement mechanism 170 is an example of a movement mechanism. The display device 180 is an example of a second display device.

[0038] Furthermore, the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made based on the knowledge of those skilled in the art. For example, in the above-described embodiment, the component mounter 10 that performs component mounting work is used as the work machine, but a work machine that performs various other work may also be used. For example, a work machine that performs assembly work, printing work, inspection work, etc. may also be used.

[0039] Furthermore, although bulk parts supply device 30 is employed as the coupling device that is coupled to the work machine, parts supply device 32 may also be employed. That is, display device 190 may be arranged so that it can move between a display position and a retracted position. In this way, display device 190 may be a display device similar to display device 180 that is arranged so that it can move between a display position and a retracted position. Furthermore, the coupling device is not limited to a device that supplies parts, but may also be a device that performs various tasks, such as a device that holds parts, such as an articulated robot, a device that assembles products, or a device that receives parts.

[0040] Furthermore, in the above embodiment, the display device 120 moves upward from the display position to the retracted position, but it may also move left or right to the retracted position. Also, the display device 120 may move toward the inside of the device body 20 to the retracted position. Also, the display device 120 may move using various methods such as rotating, swinging, sliding, and swiveling.

[0041] In the above embodiment, the display device 180 disposed in the bulk component supply device 30b displays the exact same image as the image displayed on the display device 120 disposed in the device main body 20, but may display only a portion of the image displayed on the display device 120. On the other hand, the display device 180 disposed in the bulk component supply device 30b may display an image different from the image displayed on the display device 120 disposed in the device main body 20.

[0042] Furthermore, in the above embodiment, when the bulk component supply device is connected to the device main body, the same image as that displayed on the display panel 132 of the display device 120 provided in the device main body is displayed on the display panel 182 of the display device 180 provided in the bulk component supply device 30b, but the timing at which the same image is displayed may be simultaneous with the device being connected, or may be before or after the device is connected.

[0043] Furthermore, in the above embodiment, an image is displayed on the display panel 132 of the display device 120 regardless of the position of the display device 120, that is, whether the display device is located at the display position or the retracted position. On the other hand, when the display device 120 is located at the display position, an image may be displayed on the display panel 132, and when the display device 120 is located at the retracted position, the image on the display panel 132 may not be displayed.

[0044] In the above embodiment, the moving mechanism 170 moves the display device 120 from the display position to the retracted position by the elastic force of the torsion springs 148 and 159, but the display device 120 may be automatically moved from the display position to the retracted position by the driving force of a driving device such as an electromagnetic motor. Also, the display device 120 may be manually moved from the display position to the retracted position without using the moving mechanism 170 or the like. [Explanation of symbols]
