JP 2010-135757 A

  In this type of mounting apparatus, it is necessary to identify each nozzle arranged in the nozzle replacement means in advance in order to correctly execute the automatic nozzle replacement. Therefore, when the power is turned on or when a nozzle holder is newly attached to the nozzle replacement unit, a nozzle identification operation for automatically identifying all the nozzles arranged in the nozzle replacement unit is automatically performed. As for the nozzle identification operation, as the number of nozzles arranged in the nozzle replacement means increases, the length of time required becomes a problem, and in order to improve the productivity of the mounting device, the nozzle identification operation is executed. There is a need for a technique that can eliminate the problem.

  In view of the above situation, the present specification aims to provide a technique capable of omitting the nozzle identification operation.

  Even when the power is turned on or the nozzle holder is attached, it is not always necessary to identify these nozzles again if the nozzles of the nozzle replacement means are not changed. However, in the conventional technique, it is impossible to determine whether or not the nozzle of the nozzle replacement means has been changed unless each nozzle is actually identified. Therefore, there is a problem that even if there is no actual change in the nozzle, there is no way of knowing that, so the nozzle identification operation cannot be omitted.

  With regard to the above problem, one technology disclosed in the present specification employs a configuration in which a restriction member is provided in the nozzle holder and the operation performance of the restriction member is maintained. Here, the restricting member is movable between a first position that prohibits attachment / detachment of the nozzle to / from the nozzle holder and a second position that permits the restriction member. Thus, for example, when an operator replaces the nozzle of the nozzle holder, the restricting member is surely moved to the second position. If the operation record is held in the nozzle holder, the operator or the like You can know at a later stage that you may have exchanged. On the other hand, if such an operation record is not held, it is possible to omit the nozzle identification operation because there is no possibility of replacement of the nozzle by an operator or the like.

  Based on the above technique, the present specification discloses a first electronic component mounting apparatus. The mounting device includes a nozzle holder that accommodates a plurality of nozzles, a nozzle holder that is detachably attached to the nozzle holder, a nozzle replacement unit that transfers the nozzle between the nozzle holder and the mounting head, and a nozzle holder. And a regulating member that is movable between a first position that prohibits attachment / detachment of the nozzle to / from the nozzle holder and a second position that permits the nozzle holder, and is provided in the nozzle holder and has a predetermined operation result of the regulating member. The record holding means for holding the record and the record detection means for detecting the predetermined operation record held by the record holding means. According to such a configuration, the execution of the nozzle identification operation can be omitted when there is no possibility of replacement of the nozzle by an operator or the like.

  In the mounting apparatus described above, the record holding means may hold at least a predetermined operation record of the restricting member, and as long as it holds, may hold a part of the record of operation of the restricting member or all the record of operation. The predetermined operation record here is preferably an operation record indicating the possibility that the nozzle of the nozzle holder has been replaced in a state where the nozzle holder has been removed from the nozzle replacement means. Although it is an example, it is preferable that the predetermined operation result is an operation result that the regulating member has moved from the first position to the second position in a state where the nozzle holder is removed from the nozzle replacement means. In other words, it is preferable that the record holding unit holds an operation record that the restriction member has moved from the first position to the second position at least in a state where the nozzle holder is removed from the nozzle replacement unit.

  In another technique disclosed in the present specification, a configuration in which holder information related to a plurality of nozzle holders is managed by a data server, and the holder information necessary for the mounting device can be acquired according to the nozzle holder attached to the nozzle replacement device. adopt. The holder information here is data prepared for each nozzle holder and describing the identification information of the nozzle holder in association with the identification information of each nozzle accommodated in the nozzle holder. According to such a configuration, the mounting device acquires the identification information of the nozzle holder attached to the nozzle replacement device, and acquires the holder information corresponding to the information from the data server, thereby omitting the execution of the nozzle identification operation. Can do.

  Based on the above technique, the present specification discloses a second electronic component mounting apparatus. The mounting apparatus includes a nozzle holder that accommodates a plurality of nozzles, a nozzle replacement unit that is detachably attached to the nozzle holder, and a nozzle replacement unit that transfers a nozzle between the nozzle holder and the mounting head, and a nozzle replacement unit. With respect to the mounted nozzle holder, storage means for storing the holder information that describes the identification information of the nozzle holder and the identification information of each nozzle accommodated in the nozzle holder, and the attachment / detachment of the nozzle holder with respect to the nozzle replacement means And holder information updating means for updating the holder information stored in the storage means. The holder information update means includes holder identification means for acquiring identification information of the nozzle holder attached to the nozzle replacement means, and communication means for communicatively connecting to a data server for storing the holder information regarding the plurality of nozzle holders. Prepare. Then, the holder information updating means obtains holder information corresponding to the identification information acquired by the holder identification means when the identification information acquired by the holder identification means is different from the identification information of the holder information stored in the storage means. The holder information acquired from the data server and stored in the storage means is updated. According to such a configuration, the mounting apparatus can omit the nozzle identification operation by acquiring the holder information from the data server.

  After the nozzle holder is attached to the mounting device, the nozzle arranged in the nozzle holder may be replaced or moved in the mounting device. In this case, the holder information stored in the data server is different from the actual situation of the nozzle holder and is no longer valid information. In order to avoid occurrence of such invalid holder information, the holder information stored in the data server is preferably invalidated when acquired by the mounting device. Therefore, in the second mounting device described above, it is preferable that the holder information update unit invalidates the holder information stored in the data server when the holder information is acquired from the data server. Here, as the processing for invalidating the holder information, for example, the holder information is deleted, and given information (so-called flag) is given or deleted.

  Similarly, after the nozzle holder is removed from the mounting device, the nozzle disposed in the nozzle holder may be replaced or moved by an operator or other mounting device. In this case, the holder information stored in the mounting device is different from the actual situation of the nozzle holder and is no longer valid information. In order to avoid occurrence of such invalid holder information, the holder information stored in the mounting apparatus is invalidated after being transmitted to the data server in response to the removal of the nozzle holder from the mounting apparatus. It is preferable. Therefore, in the second mounting apparatus described above, the holder information update unit transmits the holder information stored in the storage unit to the data server when the nozzle holder is removed from the nozzle replacement unit, and stores the storage information. It is preferable to invalidate the holder information stored in the means.

The mounting device 30 is disposed along with a transport path 22 for transporting the circuit board 2 together with other substrate working devices such as a solder printing device 24 and a substrate inspection device 26.

  The configuration of the mounting device 30 will be described with reference to FIGS. 2 and 3, the mounting device 30 includes a plurality of component feeders 32, a feeder holding unit 34, a mounting head 36, a head moving device 38, a substrate conveyor 40, a substrate support device 42, A control device 44 and a touch panel 46 are provided. The component feeder 32 is a device that accommodates a plurality of electronic components 4 and supplies the electronic components 4 to the mounting head 36. Each component feeder 32 is detachably attached to the feeder holding portion 34. The mounting head 36 detachably holds one or a plurality of nozzles 6 and holds the electronic component 4 using the nozzles 6. The mounting head 36 can move the nozzle 6 in the Z direction (here, the vertical direction), pick up the electronic component 4 from the component feeder 32, and mount the electronic component 4 on the circuit board 2.

  The head moving device 38 is a device that moves the mounting head 36, and mainly moves the mounting head 36 between the component feeder 32 and the circuit board 2. As an example, the head moving device 38 of the present embodiment is an XY robot, and can move the mounting head 36 in the X direction and the Y direction. The substrate conveyor 40 and the substrate support device 42 are devices that carry in, position, and carry out the circuit board 2. The circuit board 2 carried in by the board conveyor 40 is supported from below by the board support device 42. After the electronic component 4 is mounted, the circuit board 2 is transferred from the substrate support device 42 to the substrate conveyor 40 and is carried out of the mounting device 30 by the substrate conveyor 40. The board conveyor 40 constitutes a part of the conveyance path 22 (see FIG. 1) of the component mounting line 20.

  The control device 44 is configured using a computer including a CPU, a storage device, and a communication interface. The control device 44 is communicably connected to the data server 12 and exchanges various electronic data such as production programs and holder information with the data server 12.

The touch panel 46 is a display device that provides various types of information to the worker, and a user interface that receives instructions and information from the worker.

  The mounting device 30 of this embodiment has a function of automatically replacing the nozzle 6 of the mounting head 36. For this purpose, the mounting device 30 includes an identification camera 48 and a nozzle replacement device 50. The nozzle replacement device 50 can accommodate a plurality of nozzles 6 and delivers the nozzles 6 to and from the mounting head 36. The plurality of nozzles 6 are accommodated in a nozzle holder 52 attached to the nozzle replacement device 50. The nozzle holder 52 is detachable from the nozzle replacement device 50. For example, when the operator replaces the nozzle 6 of the nozzle holder 52, the nozzle holder 52 is detached from the nozzle replacement device 50.

  As shown in FIGS. 4, 5, 6, and 7, the nozzle holder 52 includes a plurality of nozzle accommodating portions 54 and a regulating member 56. Each nozzle accommodating part 54 is comprised so that the one nozzle 6 can be accommodated. Although an example, the nozzle holder 52 of the present embodiment has 24 nozzle accommodating portions 54. The nozzles 6 and the nozzle holder 52 are assigned identifiers 8 and 58, respectively. The identifier 8 of the nozzle 6 describes the nozzle identification information assigned to the nozzle 6, and the identifier 58 of the nozzle holder 52 describes the holder identification information assigned to the nozzle holder 52. The identifiers 8 and 58 in the present embodiment are two-dimensional codes, but the identifiers 8 and 58 may be other identifiers such as a barcode, RFID, mark, color, and the like.

  The regulating member 56 is a member that prevents the nozzle 6 from dropping from the nozzle holder 52. The regulating member 56 is movable between a first position (see FIGS. 4 and 5) and a second position (see FIGS. 6 and 7) and is biased toward the first position. A plurality of openings 56 a are formed in the restriction member 56 in a positional relationship corresponding to the plurality of nozzle housing portions 54. As shown in FIGS. 4 and 5, when the regulating member 56 is in the first position, the nozzle 6 is prohibited from being attached to and detached from the nozzle holder 52. On the other hand, as shown in FIGS. 6 and 7, when the restriction member 56 is in the second position, the nozzle 6 is allowed to be attached to and detached from the nozzle holder 52. For example, when the operator replaces the nozzle 6 of the nozzle holder 52, the operator removes the nozzle holder 52 from the nozzle replacement device 50, moves the regulating member 56 from the first position to the second position, and the nozzle holder 52. The nozzle 6 is attached to and detached from the nozzle. When the nozzle holder 52 is attached to the nozzle replacement device 50, the restriction member 56 is opened and closed by the nozzle replacement device 50. That is, although not shown, the nozzle replacement device 50 includes an opening / closing mechanism that moves the regulating member 56 between the first position and the second position.

  As shown in FIG. 4 and FIG. 6, the nozzle holder 52 further includes a result holding unit 60. The record holding unit 60 is a mechanism that holds a predetermined operation record of the regulating member 56. The predetermined operation here is an operation result that the regulating member 56 has moved from the first position to the second position in a state in which the nozzle holder 52 is removed from the nozzle replacement device 50. Hereinafter, this operation result is referred to as “open result”. Although it is an example, the result holding part 60 of a present Example displays either "white" or "red" through the display windows 52w and 56w. Normally, the record holding unit 60 displays “white”. Then, when the regulating member 56 moves from the first position to the second position with the nozzle holder 52 removed from the nozzle replacement device 50, the result holding unit 60 changes to display “red” and maintains it. Keep doing. That is, even if the restricting member 56 subsequently returns to the first position, the result holding unit 60 continues to display “red”. The record holder 60 is reset to a “white” display after the nozzle holder 52 is attached to the nozzle replacement device 50 and the display is read by the mounting device 30.

  Although it is an example, with reference to FIGS. 8-13, the structure of the results holding part 60 of a present Example is demonstrated. The record holding unit 60 is a movable member supported by the nozzle holder 52, and includes a white first portion 60a and a red second portion 60b. As shown in FIG. 8, when the restricting member 56 is in the first position, the first portion 60a of the result holding unit 60 is exposed to the outside through the display windows 52w and 56w. When the restricting member 56 moves from the first position to the second position, as shown in FIG. 8, the connecting member 62 connected to the restricting member 56 is moved from one side (right side in the drawing) with respect to the result holding unit 60. As a result, the record holding unit 60 moves. As a result, the second portion 60b of the result holding unit 60 is exposed to the outside through the display windows 52w and 56w. Thereafter, even if the regulating member 56 returns to the first position, the position of the result holding unit 60 is maintained.

  As shown in FIGS. 10 and 11, when the nozzle holder 52 is attached to the nozzle changing device 50, the connecting member 62 of the nozzle holder 52 is engaged with the opening / closing mechanism 70 of the nozzle changing device 50. The opening / closing mechanism 70 of the nozzle replacement device 50 is a mechanism that moves the regulating member 56 of the nozzle holder 52 between the first position and the second position. The opening / closing mechanism 70 has an engaging portion 72 for engaging with the connecting member 62, and is connected to the regulating member 56 through the connecting member 62. Here, the connecting member 62 of the nozzle holder 52 is supported via an elastic member 64. As a result, as shown in FIG. 11, when the opening / closing mechanism 70 engages with the connecting member 62, the connecting member 62 moves upward, and contact between the connecting member 62 and the performance holding unit 60 is prohibited. That is, while the nozzle holder 52 is attached to the nozzle replacement device 50, the result holding unit 60 is invalidated.

  The opening / closing mechanism 70 of the nozzle replacement device 50 further includes an operation unit 74. The operation unit 74 is supported via an elastic member 76. As shown in FIGS. 11 and 12, when the opening / closing mechanism 70 moves the regulating member 56 to the second position, the operation unit 74 of the opening / closing mechanism 70 is on the other side (right side in the drawing) with respect to the result holding unit 60. Abut. Thereafter, when the opening / closing mechanism 70 moves the restriction member 56 to the first position, the operation unit 74 pushes the result holding unit 60, whereby the result holding unit 60 is changed to the display of “white”. That is, the “opening record” held by the record holding unit 60 is invalidated. As described above, the nozzle replacement device 50 is configured to reset the result holding unit 60 to “white” when the regulating member 56 is opened and then closed.

  In addition, the specific structure of the result holding part 60 is not specifically limited. The record holding unit 60 is not limited to the mechanical structure as described above, and is an electrical device that detects attachment / detachment with the nozzle replacement device 50 and the operation of the regulating member 56 with a sensor and switches display using an LED or the like. It may have a simple structure. Further, the result holding unit 60 is not limited to the one that displays visually, but may store the operation result in a storage element (for example, RFID) that can be read from the outside. The record holding unit 60 holds the “open record” at least in a state where the nozzle holder 52 is removed from the nozzle changer 50, and the “open record” between the attachment to the nozzle changer 50 and the removal. As long as "" is invalidated (for example, erased), the specific configuration is not particularly limited.

  The identification camera 48 can read the identifiers 8 and 58 attached to the nozzle 6 and the nozzle holder 52, respectively. Further, the identification camera 48 can read the operation results held in the result holding unit 60 by identifying “white” and “red” displayed by the result holding unit 60. Similar to the mounting head 36, the identification camera 48 is attached to the head moving device 38, and can be moved in the X direction and the Y direction by the head moving device 38. The operations of the identification camera 48 and the head moving device 38 are controlled by the control device 44.

  The control device 44 executes the nozzle identification operation at a predetermined timing such as when the mounting device 30 is turned on or when the nozzle holder 52 is replaced. The nozzle identification operation is an operation in which the control device 44 controls the identification camera 48 and the head moving device 38 to read the identifier 58 of the nozzle holder 52 attached to the nozzle replacement device 50 and the identifier 8 of each nozzle 6. is there. As a result, the control device 44 can create and store holder information relating to the nozzle holder 52 attached to the nozzle replacement device 50 in association with the holder identification information and each nozzle identification information. The control device 44 recognizes the nozzles 6 arranged in the respective nozzle accommodating portions 54 based on the holder information stored by itself, and executes an operation related to automatic replacement of the nozzles 6 of the mounting head 36. At this time, the control device 44 mainly controls the mounting head 36, the head moving device 38, and the nozzle changing device 50.

  Regarding the nozzle identification operation, as the number of nozzles 6 arranged in the nozzle replacement device 50 increases, the length of the required time becomes a problem. Therefore, in the mounting device 30 of the present embodiment, the execution of the nozzle identification operation can be omitted by determining whether or not the nozzle identification operation is necessary even at a predetermined timing at which the nozzle identification operation is to be performed. Hereinafter, with reference to FIGS. 14 and 15, processing executed by the control device 44 including determination of necessity of the nozzle identification operation will be described.

  As shown in FIG. 14, at a predetermined timing when the nozzle identification operation is to be performed (YES in S <b> 12) such as when the mounting device 30 is turned on or when the nozzle holder 52 is attached to the nozzle replacement device 50. 44 reads the identifier 58 of the nozzle holder 52 and acquires the holder identification information (S14). Next, the control device 44 determines whether or not the acquired holder identification information matches the holder identification information of the holder information stored by itself (S16). Here, the attachment / detachment of the nozzle holder 52 with respect to the nozzle replacement device 50 may be detected by a sensor provided in the nozzle replacement device 50, or the operator who attached / detached the nozzle holder 52 teaches the control device 44 through the touch panel 46. May be.

  For example, if the same nozzle holder 52 is attached when the power of the mounting device 30 is turned off and when the power of the mounting device 30 is turned on again, the above two pieces of holder identification information match. In such a case (YES in S16), the control device 44 reads the result holding unit 60 of the nozzle holder 52 (S26), and determines whether or not the “open result” is held (S28). That is, it is determined whether or not the display of the record holding unit 60 is “red”. If “open record” is not held (NO in S28), it means that the nozzle 6 of the nozzle holder 52 has not been replaced. Therefore, the control device 44 omits the execution of the nozzle identification operation (S32), assuming that the holder information stored by itself is valid. On the other hand, if the “opening record” is held (YES in S28), the holder information stored therein is invalidated (S30), the nozzle identification operation is executed (S32), and the holder information is stored. Update. This is because the operator may remove the nozzle holder 52 from the nozzle replacement device 50 and replace the nozzle 6 of the nozzle holder 52 while the power supply of the mounting device 30 is shut off. Here, in order to invalidate the holder information, for example, a predetermined flag may be added to or deleted from the holder information, or the holder information may be deleted.

  On the other hand, when the above-mentioned two holder identification information does not correspond (it is NO at S16), control device 44 invalidates the holder information which self memorizes (S18). Next, the control device 44 accesses the data server 12 (YES in S20), and acquires holder information corresponding to the holder identification information acquired from the nozzle holder 52 from the data server 12 (YES in S22). And the control apparatus 44 performs the process which invalidates the said holder information memorize | stored in the data server 12 (S24). Thereby, valid holder information for the nozzle holder 52 is stored only in the mounting device 30 to which the nozzle holder 52 is attached.

  Next, the control device 44 reads the result holding unit 60 of the nozzle holder 52 (S26), and determines whether or not the “opening result” is held (S28). As described above, if the “open record” is not held (NO in S28), the execution of the nozzle identification operation (S32) is omitted. In addition, the case where the data server 12 does not exist, or the case where the data server 12 exists but the holder information effective in the data server 12 does not exist is also assumed. Therefore, the control device 44 executes the nozzle identification operation when access to the data server 12 fails (NO in S20) or when valid holder information cannot be acquired from the data server 12 (NO in S22). (S32) and create holder information by itself. As described above, the control device 44 has stored valid holder information in advance (YES in S16) or has acquired valid holder information from the data server 12 (YES in S22). When the “open record” is not held in the nozzle holder 52, the nozzle identifying operation is omitted.

  Next, an operation performed by the control device 44 when the nozzle holder 52 is removed from the nozzle replacement device 50 will be described with reference to FIG. For example, when the operator removes the nozzle holder 52 from the nozzle replacement device 50 (S42), the control device 44 tries to access the data server 12 (S44). If the access to the data server 12 is successful (YES in S44), the control device 44 transmits the holder information stored therein to the data server 12 (S46). Thereby, the holder information of the nozzle holder 52 removed from the nozzle replacement device 50 is stored in the data server 12 as valid holder information. Next, the control device 44 invalidates the holder information of the nozzle holder 52 stored therein (S48). Thereby, while the nozzle holder 52 is removed from the mounting apparatus 30, valid holder information of the nozzle holder 52 is stored only in the data server 12.

  As described above, in the mounting device 30 of the present embodiment, the restriction member 56 is provided in the nozzle holder 52, and the “open record” of the restriction member 56 is held in the nozzle holder 52. The mounting device 30 can determine whether or not there is an “open record” held in the nozzle holder 52 when the nozzle holder 52 is attached to the nozzle replacement device 50. Thereby, the mounting device 30 can appropriately omit the execution of the nozzle identification operation in accordance with the presence / absence of the “open record” held in the nozzle holder 52.

  Further, in the system 10 of the present embodiment, the holder information regarding the plurality of nozzle holders 52 is managed by the data server 12, and when the nozzle holder 52 is attached to the nozzle replacement device 50, the mounting device 30 is connected to the nozzle holder. 52 holder information can be acquired. Here, when the mounting apparatus 30 acquires the holder information from the data server 12, the holder information stored in the data server 12 is invalidated. Thereby, valid holder information for the nozzle holder 52 is stored only in the mounting device 30 to which the nozzle holder 52 is attached. When the nozzle holder 52 is removed from the nozzle replacement device 50, the holder information is transmitted from the mounting device 30 to the data server 12, and the holder information stored in the mounting device 30 is invalidated. Accordingly, when the nozzle holder 52 is attached to another mounting device 30, the other mounting device 30 can acquire holder information of the nozzle holder 52 from the data server 12.

  Specific examples of the present invention have been described in detail above, but these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples illustrated above.

  As illustrated in FIG. 16, the nozzle holder 52 may include a plurality of regulating members 56 and a plurality of achievement holding units 60. In this case, each result holding unit 60 may hold a predetermined operation result (for example, “open result”) for one corresponding restricting member 56. Although FIG. 16 shows an example having two sets of restriction members 56 and a result holding unit 60, the nozzle holder 52 can also have three or more sets of restriction members 56 and a result holding unit 60.

  In the system 10 described in the present embodiment, a plurality of nozzle holders 52 exist, and it is assumed that an arbitrary nozzle holder 52 is attached to each mounting device 30. However, as another embodiment, it may be assumed that the same nozzle holder 52 is always attached to each mounting device 30. In this case, the mounting device 30 can determine whether or not the nozzle identification operation is necessary based on only the operation results held in the nozzle holder 52.

  The technical elements described in this specification or the drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technology illustrated in the present specification or the drawings achieves a plurality of objects at the same time, and has technical utility by achieving one of the objects.
