Description

  The present invention relates to a component mounting machine and a component mounting method applied thereto, and in particular, a component mounting machine in which a plurality of mounting heads cooperate to mount a component on a single board, and a component mounting method. About.

  2. Description of the Related Art Conventionally, there is a component mounter that mounts components while two mounting heads perform cooperative operations on a single board.

  In such a component mounting machine, it is necessary to control the operation of each mounting head so that the two mounting heads do not interfere with each other.

  Specifically, the interference area and the free area are divided according to the movable area of the two mounting heads, the size of the board to be mounted, etc., and the component mounter performs control corresponding to each area. It has become.

  Here, the interference area is an area to be exclusively controlled so that the two mounting heads cannot mount components at the same time in order to prevent the two mounting heads from interfering with each other. The free area is an area in which one of the two mounting heads is allowed to mount a component in the interference area, and the other is permitted to mount the component. A good area.

  In this way, when an interference area and a free area are set in the component mounter, and the components are mounted on the board by coordinating the two mounting heads, mounting in the interference area and mounting in the free area are two. The production efficiency of the mounting board changes depending on how it is distributed to the head.

  For example, the component mounting method disclosed in Patent Document 1 adopts a mode in which when one mounting head is not arranged in the interference area, the other mounting head preferentially performs mounting in the interference area. Has been. Also, if there is one mounting head in the interference area, the other mounting head cannot be mounted in the interference area, so only perform mounting in the free area, and if there are no parts to mount in the free area, The other mounting head waited without doing anything until the mounting of one mounting head in the interference area was completed.

JP 2003-243890 A

  However, in the component mounting method, when it is determined that one mounting head is in the interference area after the other mounting head has picked up the component to be mounted in the interference area, the other mounting head places the component in the free area. It was not possible to mount, and there was no choice but to stand by with the components to be mounted in the interference area.

  In such a component mounting method, a lot of so-called play time in which the other mounting head does not contribute to the mounting occurs, negatively affecting the production efficiency of the mounting board.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a component mounting method and a component mounter that improve the production efficiency of a mounting board by effectively using a mounting head.

  In order to achieve the above object, a component mounting method according to the present invention is applied to a component mounting machine in which a first head and a second head, which are mounting heads having a plurality of nozzles, cooperate to mount components on a substrate. In the component mounting method, the component mounter mounts components at the same time in the first head and the second head in order to prevent interference between the first head and the second head. Is prohibited, and a free area in which one of the first head and the second head is allowed to mount a component even during the period when the component is mounted in the interference area. Is set and exclusive control of the operation of the first head and the second head is performed so that only one of the first head and the second head has the right to mount the component in the interference area. Exclusive control step, an occupation right confirmation step for confirming whether or not the first head has an occupation right while there is an empty nozzle that is a nozzle to which no component is adsorbed to the second head, and the occupation right And a free suction step of sucking a component that can be mounted in a free area by the empty nozzle of the second head when it is determined in the confirmation step that the first head has an occupation right.

  Further, when it is determined in the occupation right confirmation step that the first head does not have an occupation right, the second head obtains an occupation right, and an interference area is formed in the empty nozzle of the second head. An interference suction step for sucking components that can be mounted may be included.

  According to this, the presence or absence of the right to occupy the first head can be confirmed while there is an empty nozzle. When the right to occupy the first head, the second head uses the empty nozzle without waiting. You can continue to mount components in the free area. Therefore, it is possible to avoid a situation in which the second head is filled with the components mounted in the interference area even though the first head has the occupation right. Therefore, it is possible to mount in the free area using at least one empty nozzle of the second head, and it is possible to improve the production efficiency of the mounting board by suppressing the time that the second head waits.

  The occupation right confirmation step may include a first confirmation step for confirming whether or not the first head has the occupation right while all the nozzles of the second head are empty nozzles.

  By executing the first confirmation step, components that can be mounted in a desired area can be adsorbed to all the nozzles of the second head. That is, when the first head has the occupation right, the free suction step can be executed for all the empty nozzles. When the first head does not have the occupation right, the occupation right acquisition step, the interference suction step, Can be executed.

  Further, in the occupation right confirmation step, in the first confirmation step, when it is determined that the first head has the occupation right, the first head after at least one of the nozzles of the second head is not an empty nozzle. A second confirmation step of confirming whether one head has the exclusive right.

  According to this, when it is confirmed that the right to occupy the first head is lost while there is an empty nozzle after at least one of the nozzles of the second head is not an empty nozzle, an interference suction step is performed on the empty nozzle. Can be executed. Therefore, it is possible to complete the mounting efficiently and early in the interference area that is exclusively controlled.

  In the free suction step, components that can be mounted in the interference area may be preferentially picked up.

  According to this, when the right to occupy the first head is lost during the part picking process, it is possible to mount in the interference area with the part picked up with the right to occupy the first head. Therefore, it is possible to complete the mounting more efficiently and quickly in the interference area that is exclusively controlled.

  In order to achieve the above object, a component mounter according to the present invention is a component mounter in which a first head and a second head, which are mounting heads having a plurality of nozzles, cooperate to mount components on a board. In order to prevent interference between the first head and the second head, an interference area where the first head and the second head are prohibited from mounting components at the same time, and the first head A free area in which one of the head and the second head is allowed to mount a component even when the component is mounted in the interference area is set, and the first head and the second head An exclusive control unit that exclusively controls the operation of the first head and the second head so that only one of the two heads has the right to mount the component in the interference area, and the component in the second head An occupancy right confirmation unit that confirms whether or not the first head has an occupancy right while there are empty nozzles that are not sucked, and the occupancy right confirmation unit has an occupancy right in the first head When it is determined, the controller includes a controller that adsorbs a component that can be mounted in the free area to the empty nozzle of the second head and mounts the component in the free area.

  According to this, when the first head has the occupation right, the second head can continue to mount components in the free area using the empty nozzle without waiting. Therefore, it is possible to improve the production efficiency of the mounting board by suppressing the time that the second head waits.

  Note that executing a program for causing a computer to execute each process included in the component mounting method also corresponds to the implementation of the present invention. Of course, implementing the recording medium in which the program is recorded also corresponds to the implementation of the present invention.

  According to the present invention, in a component mounter in which two mounting heads cooperate with each other to mount a component on a board, the mounting head without occupying right also mounts the component in the free area while monitoring the occupying right. Thus, it is possible to suppress the play time that the mounting head without the occupation right waits. Therefore, the production efficiency of the mounting board can be improved.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram schematically showing an outline of a component mounter in an embodiment of the present invention.

  As shown in the figure, the component mounting machine 100 is an apparatus that constitutes a part of a production line for producing a mounting board. For example, the component mounting machine 100 is continuously loaded from the previous process of printing solder on the surface of the board 20. This is a device that mounts a plurality of components on a substrate 20 to be produced, continuously produces a mounting substrate, and carries it out to a subsequent process.

  FIG. 2 is a plan view schematically showing an outline of the main configuration and operation of the component mounter.

  The component mounting machine 100 is a device that performs a mounting operation on a single board 20 in cooperation with each other, and the first equipment 110 and the second equipment 120 that have the capability of independently producing a mounting board. It has. The first equipment 110 and the second equipment 120 are arranged to face each other with the substrate 20 to be mounted interposed therebetween. For convenience of explanation, the direction in which the first equipment 110 and the second equipment 120 are arranged is referred to as the front-rear direction of the component mounting machine 100, and is the Y-axis direction in the drawing.

  The first equipment 110 includes a first component supply unit 115, a first beam 112, a first head 111, and a first camera 116. The second facility 120 has the same configuration as the first facility 110 and includes a second component supply unit 125, a second beam 122, a second head 121, and a second camera 126.

  Each of the first beam 112 and the second beam 122 is a rigid body extending in the X-axis direction, and is slidably connected to a Y beam (not shown) arranged extending in the Y-axis direction. It is a member that can move (translate) in the Y-axis direction while maintaining the state of extending in the axial direction.

  The first head 111 is a device that includes a plurality of first nozzles 113, can suck and transport a plurality of components, and can mount the components at a predetermined mounting point. The first head 111 is attached to the first beam 112 and is linearly movable along the first beam 112 so as to reciprocate in the X-axis direction.

  Accordingly, the first head 111 determines the position in the Y-axis direction by translating the first beam 112 in the Y-axis direction, and moves in the X-axis direction by moving in the X-axis direction along the first beam 112. The position is determined. From the above, the first head 111 is freely movable in the XY plane.

  Since the second head 121 has the same configuration and function as the first head 111, a description thereof will be omitted.

  In FIG. 2, the first head 111 has four first nozzles 113, but the number of the first nozzles 113 included in the first head 111 is not particularly limited. Moreover, although the 1st nozzle 113 arrange | positioned along with a straight line is described, this is also not specifically limited, The 1st head 111 has two 1st nozzles 113 arrange | positioned along with a straight line. It does not matter if it has a line.

  Further, the arrangement pattern of the second nozzles 123 is not necessarily the same as that of the first head 111, and the second head 121 can adopt any arrangement pattern.

  Hereinafter, the first head 111 and the second head 121 may be collectively referred to as “mounting head”. The first nozzle 113 and the second nozzle 123 may be collectively referred to as “nozzles”.

  The first camera 116 is a camera for capturing an image of the state of a component that is attracted by the first nozzle 113 of the first head 111. In the case of the present embodiment, the first camera 116 is an apparatus that captures an image of the part that the first head 111 sucks from below. Then, by analyzing the image acquired by the first camera 116, the position of the component adsorbed by the first nozzle 113 in the XY direction, the shift in the θ direction, the inclination of other abnormal components, the first nozzle 113, and the like. Information such as whether or not the component is adsorbing parts is acquired.

  The second camera 126 has the same function and configuration as the first camera 116.

  The first component supply unit 115 is a portion to which components that the first head 111 sucks are supplied. For example, a plurality of tape feeders and the like are attached to the first component supply unit 115, and each tape feeder intermittently supplies different types of components or the same types of components. The function and configuration of the second component supply unit 125 are the same as those of the first component supply unit 115.

  The component mounting machine 100 further includes a transport unit 129 for transporting the substrate 20 intermittently.

  The transport unit 129 is a device that transports the loaded substrate 20 to the mounting stage, holds the substrate 20 on the mounting stage during mounting, and unloads the substrate from the component mounter 100 when mounting is completed. In the case of the present embodiment, the transport unit 129 is a conveyor including a pair of rails, and can transport the substrate 20 with the opposite edges of the substrate 20 being sandwiched. In addition, one rail of the transport unit 129 is movable in the Y-axis direction according to the length of the transported substrate 20 in the Y-axis direction.

  In the component mounting machine 100 having such a configuration, each of the first head 111 and the second head 121 repeats a series of operations of component adsorption, conveyance, mounting, and return, so that a plurality of components are placed on the substrate 20. To implement. Note that a series of operations in one repetition of this series of operations is referred to as a “turn”.

  Specifically, as indicated by the arrow in FIG. 2, the first head 111 first picks up the component from the first component supply unit 115 in one turn. Specifically, after the first head 111 is transported to a predetermined location above the first component supply unit 115, one of the first nozzles 113 is lowered and the tip of the first nozzle 113 is moved to the first component supply unit 115. It is made to contact | abut to the components supplied to. The inside of the first nozzle 113 is in a vacuum state, and the component is adsorbed to the first nozzle 113 by atmospheric pressure. Next, the first head 111 moves in place in the first component supply unit 115 and is referred to as a first nozzle 113 (hereinafter referred to as “empty nozzle”) on which no component has been sucked yet. Similarly, it is written as “empty nozzle”.) By repeating the above operation, the first head 111 sucks components according to the number of the first nozzles 113.

  When the arrangement pitch of the components in the first component supply unit 115 matches the pitch of the first nozzle 113 and the arrangement of the components to be sucked in the first component supply unit 115 matches, a plurality of first It is also possible to perform so-called simultaneous suction, in which a plurality of parts are sucked simultaneously by lowering the nozzle 113 at the same time.

  Next, the first head 111 moves while adsorbing the components, and passes above the first camera 116. At this time, the sucked component is recognized by the first camera 116. Then, it is determined whether or not the component is correctly sucked, and information on position correction and rotation correction necessary for mounting the sucked component on the substrate 20 is acquired. In the case of this embodiment, this operation is included in the conveyance in the turn.

  Thereafter, the first head 111 conveys the component to a predetermined position above the substrate 20, and lowers the nozzle that adsorbs the component at the predetermined position to release the adsorption state, so that the component is applied to the substrate 20. Install.

  The first head 111 that has completed the mounting of the component in one turn returns to the upper side of the first component supply unit 115 to attract the component again.

  The first head 111 mounts components on the substrate 20 by repeating such a series of operations (turns).

  Similarly, the second head 121 also mounts a component on the board 20 by repeating a turn including adsorption, conveyance, mounting, and return of the component.

  Further, the first head 111 and the second head 121 of the component mounter 100 can move mechanically independently in the XY plane, and any head mounts components at the same position on the substrate 20. There is an area that can be. For this reason, the component mounter 100 has an interference area which is an area exclusively controlled by software in order to eliminate interference between the first head 111 and the second head 121 moving in the same area, and the other. The movable areas of the first head 111 and the second head 121 are set so as to distinguish the free area, which is an area that can be freely moved and mounted without worrying about the movement of the mounting head.

  Specifically, as shown in FIG. 2, an interference area is set near the center of the substrate 20 in the Y-axis direction, and the first equipment 110 side and the second equipment 120 side sandwich the interference area. A second free area is set. The first free area and the second free area may be collectively referred to as a free area.

  The interference area is obtained from the size of the area (component mounting area) on which the component on the substrate 20 is to be mounted, the movable region and the size of the first head 111 and the second head 121, and the like.

  FIG. 3 is a block diagram schematically showing the main functional configuration of the component mounter together with the mechanism configuration.

  As shown in the figure, the component mounter 100 includes an occupation right confirmation unit 130, a control unit 140, an exclusive control unit 141, a free suction unit 131, an interference suction unit 132, a mechanism unit 102, and a storage unit. 135.

  The mechanism unit 120 shows the entire mechanical structure such as devices and members provided in the component mounter 100 as described in FIG. 2, and includes, for example, a first facility 110 and a second facility 120.

  The control unit 140 is a processing unit that controls the operation of each mechanism provided in the component mounting machine 100. For example, the control unit 140 controls the operations of component adsorption, conveyance, mounting, and return for the first head 111.

  The exclusive control unit 141 is a process that regulates the control of the control unit 140 with respect to the first head 111 and the second head 121 so that only one of the first head 111 and the second head 121 mounts a component in the interference area. Part.

  The exclusive control unit 141 prohibits one of the first head 111 and the second head 121 from mounting a component in the interference area while the other is mounting the component in the interference area. This prevents the first head 111 and the second head 121 from interfering with each other. Specifically, only one of the first head 111 and the second head 121 has a right to mount a component in the interference area (may be referred to as “occupation right”). Control of the first head 111 and the second head 121 is restricted. The exclusive control unit 141 determines which of the first head 111 and the second head 121 is to be given the occupation right based on the operation state of the component mounting machine 100.

  The occupancy right confirmation unit 130 is a processing unit that confirms at which the occupancy right is set to the first head 111 or the second head 121 by the exclusive control unit 141 at a predetermined timing. The predetermined timing is when the first head 111 has an empty nozzle and when the second head 121 has an empty nozzle. The contents do not exclude confirmation of the location of the exclusive right other than the period.

  When it is determined by the occupation right confirmation unit 130 that the first head 111 has the occupation right, the free adsorption unit 131 causes the control unit 140 to adsorb components that can be mounted in the free area with the empty nozzle of the second head 121. A processing unit for instructing. Further, when the occupation right confirmation unit 130 determines that the second head 121 has the occupation right, the free adsorption unit 131 adsorbs a component that can be mounted in the free area with the empty nozzle of the first head 111. 140 is instructed.

  The free suction unit 131 acquires components (common components) that can be mounted in the free area and can also be mounted in the interference area from the storage unit 135, and controls so as to preferentially suck this component. It is also possible to instruct the unit 140.

  When the occupation right confirmation unit 130 determines that the first head 111 does not have an occupation right, the interference suction unit 132 causes the control unit 140 to suck components that can be mounted in the interference area with the empty nozzle of the second head 121. A processing unit for instructing. In addition, when the occupation right confirmation unit 130 determines that the second head 121 has no occupation right, the interference suction unit 132 controls the control unit to suck components that can be mounted in the interference area with the empty nozzle of the first head 111. 140 is instructed.

  The storage unit 135 is a processing unit or device that stores information related to mounting of components such as mounting information and a component library. For example, when acquiring information from an external device via a network connected to the component mounting machine 100 and temporarily storing the information, the information is stored regardless of whether the storage location is a semiconductor or a magnetic material. The part that exhibits the function is the storage unit 135. In the present embodiment, the storage unit 135 is described as a hard disk.

  Each processing unit is realized by, for example, a CPU (Central Processing Unit) based on a control program for each processing.

  Next, the operation of the component mounter 100 having the above configuration will be described.

  FIG. 4 is a flowchart showing an outline of the component mounting method.

  Hereinafter, the operation of the component mounting machine 100 will be described focusing on the case where the control unit 140 controls the second head 121. The following description can be similarly applied to the case where the first head 111 is controlled.

  First, the occupation right confirmation unit 130 confirms whether or not the first head 111 has the occupation right while there is an empty nozzle in the second head 121 (S101: occupation right confirmation step). In the case of the present embodiment, first, at the stage where all the second heads 121 are empty nozzles, it is determined whether or not there are empty nozzles (S100). In the confirmation step (S101), it is confirmed whether or not the first head 111 has an occupation right while all the second nozzles 123 of the second head 121 are empty nozzles. This step is a first confirmation step.

  Note that the occupation right confirmation step (S101) is executed a plurality of times in the circulating step (S100 → S101 → S104 → S107 → S100), and there are parts adsorbed to the second head 121, but there are also empty nozzles. In some cases, it may be confirmed whether or not the first head 111 has an occupation right. This step is a second confirmation step.

  When the first head 111 has an occupation right (S104, Y), the control unit 140 can be mounted on the second head 121 in the second free area based on an instruction from the free suction unit 131 (in the case of writing “free component”). In the second component supply unit 125 (S107: free suction step). At this time, components (common components) that can be mounted also in the interference area may be preferentially sucked.

  Here, the common component is, for example, a component in which the component type of any component in the components mounted in the free area matches the component type of any component in the components mounted in the interference area. is there. In addition, common parts vary depending on the turn. For example, if the first head 111 has already finished mounting the component to be mounted in the interference area, there is no component that can be mounted in the interference area in the subsequent turn, so there is no common component. In other words, the common part is a part that the first head 111 sucks or is scheduled to suck in a certain turn, and can be mounted in the interference area or in the free area depending on the location of the occupation right. It is a certain part. The same applies to the second head 121.

  In the free component adsorption step (S107) in the present embodiment, the free component is adsorbed by one empty nozzle, and then the process proceeds to the next step. The free component suction method in the free component suction step (S107) is not limited to the present embodiment.

  Next, the process returns to the step of determining whether or not there is an empty nozzle in the second head 121 (S100). If there is an empty nozzle (S100, Y), the occupation right confirmation process (S101) is repeated.

  When it is determined that the first head 111 does not have an occupation right (S104, N), the exclusive control unit 141 gives the second head 121 an occupation right. That is, the second head 121 acquires the occupation right (S113: exclusive control step).

  Here, based on an instruction from the interference suction unit 132, the control unit 140 causes the second head 121 to suck a component that may be mounted in the interference area (may be referred to as “interference component”) (S116: interference suction step). At this time, the common parts may be sucked preferentially.

  In the case of the present embodiment, if the right to occupy the second head 121, the remaining empty nozzles adsorb all the interference components, so in the interference component adsorption step (S116), the interference components are adsorbed to all the empty nozzles. Then, the process proceeds to the conveyance step (S119).

  In the circulating step (S100 → S101 → S104 → S107 → S100), when it is determined that there is no empty nozzle (S100, N), the second head 121 conveys the component above the substrate 20 (S119). . In the present embodiment, whether or not to move to the transport step (S119) is determined based on whether or not there is an empty nozzle, but other determination conditions may be set separately or additionally. For example, a part to be mounted in one turn may be determined in advance, and it may be determined based on whether or not all the determined parts have been sucked. Further, although the occupation right is acquired, it may be determined whether or not the free part is sucked to the mounting head. In this case, the process proceeds to the transport process (S119), and a free part may be mounted in the free area for the time being.

  Next, the occupation right confirmation unit 130 confirms again whether or not the first head 111 has the occupation right (S121). When the first head 111 has the occupation right (S122, Y), the free component attracted by the second head 121 is mounted on the portion corresponding to the second free area of the substrate 20 (S125). Here, when the second head 121 sucks the common part, the common part may be mounted in the second free area.

  When the mounting step (S125) is completed in the free area, the second head 121 returns to the second component supply unit 125 (S34), and one turn is completed.

  On the other hand, when the first head 111 has no occupation right (N in S122), the interference component attracted by the second head 121 is mounted on the interference area corresponding portion of the substrate 20 (S128). Here, when the second head 121 sucks the common component based on the instruction of the free suction unit 131, the common component may be preferentially mounted in the interference area.

  Next, when the second head 121 has the occupation right, the occupation right is released (S131: exclusive control step), the process returns to the second component supply unit 125 (S134), and one turn is completed.

  Finally, it is determined whether or not all the components have been mounted in the interference area (S137), and if there are any components that the second head 121 mounts in the interference area (S137, N), the process returns to S100 and described above. Repeat steps. On the other hand, if the mounting of all the components in the interference area has been completed, this routine is terminated and the routine proceeds to another routine. In other routines, the remaining free parts regardless of the occupation right are attracted to the second head 121 and mounted on the free area. When all the free area parts are mounted, the mounting work on the board is finished. Routine.

  In addition, this invention is not limited to the said embodiment. For example, when the occupancy right is confirmed when all the nozzles of the second head 121 are empty nozzles (S101, S104), the first head has the occupancy right, so some free parts are picked up and the occupancy right is confirmed again. When the first head has no occupation right when (S101), the second head obtains the occupation right and sucks the interference component (S113), that is, the second head 121 is the interference component. If both the free part and the free part are sucked, a step of mounting in the second free area may be added before the feedback step (S134) after the interference area mounting step (S128) is completed.

  In addition, when all the nozzles of the second head 121 are empty nozzles and the right to occupy is confirmed (S101, S104), the first head 111 has the right to occupy (Y in S104). Is adsorbed (S107). Then, when the empty nozzle remains (Y in S104), the occupation right is confirmed again (S101). If the first head 111 does not have the occupation right (N in S104), the second head 121 has the occupation right. Is acquired (S113). Thereafter, the interference component is not attracted (S116) as in the flowchart shown in FIG. 4, but the free component already attracted by the second head 121 is placed on the substrate while the second head 121 has the occupation right. It may be transported (S119), the sucked free part is mounted in the free area, and returned to the second part supply unit 125 without releasing the occupation right (S134). In the next turn of the second head 121, since the second head 121 has the right to occupy and all are empty nozzles, the interference component is picked up by one turn and moved onto the substrate 20 to the interference area. It is possible to mount an interference component.

  In the present embodiment, the step of releasing the exclusive right (S131) is always executed, but the timing for releasing the exclusive right can be arbitrarily set. For example, after acquiring the occupation right, the interference priority mode may be used in which the interference component is continuously mounted until the interference component disappears.

  In the above embodiment, when the occupation right is transferred to the second head 121, all the empty nozzles thereafter pick up the interference components. However, the present invention is not limited to this. For example, the occupation right is confirmed in a state where the interference part is adsorbed to a part of the second head 121, and if the occupation right cannot be acquired, the free part is adsorbed to the free area. It doesn't matter what you implement. In this case, since the interference component attracted to a part of the second head 121 cannot be mounted in the interference area unless it is a common component, the second head 121 remains attracted and is carried over to the next turn. Become.

  Further, when the second head 121 acquires the occupation right in the occupation right acquisition step (S113) and sucks the interference part, the occupation right confirmation step (S121) and the determination step (S122) are omitted, and the interference area mounting step. (S128) It does not matter. Of course, if the second head 121 also adsorbs a free part, it is possible to mount the free part in the free area.

  If the component mounting method is applied to the component mounting machine 100, the mounting head that does not have the occupation right even though the interference component is adsorbed to a part of the nozzle of the mounting head is free to the empty nozzle. It becomes possible to attach free parts to the free area.
