Description

  The present invention relates to a production management apparatus.

  2. Description of the Related Art Conventionally, a surface mounter that sucks an electronic component supplied through a component supply device by a suction nozzle and mounts it on a substrate is widely known. In such surface mounters, different types of boards may be continuously produced. In this case, if the board type changes, the type of electronic components mounted on the board also changes. Therefore, it was necessary to temporarily change the operation of the surface mounter and perform a setup change operation to replace the component supply device.

In recent years, a technology has been disclosed in which a plurality of component supply devices can be attached to a surface mounter in a lump by means of a lump exchanging cart or the like, since such a changeover operation leads to a reduction in operating rate. Has been. In this way, it is possible to attach and remove a plurality of component supply devices at once, and there is an effect that the time for stopping the surface mounter can be shortened at the time of setup change.
JP 2002-319791 A

If a plurality of parts supply devices are replaced at once as described above, the time for stopping the surface mounter during setup change can be shortened to some extent, but it must be stopped for a certain period of time. There was room for improvement.
The present invention has been completed based on the above-described circumstances, and an object thereof is to produce different types of substrates with a surface mounter without lowering the operation rate.

  The present invention uses a surface mounter in which a plurality of sets of component supply devices in which a plurality of component supply devices are arranged side by side on a mounting plate are detachably installed on a base, and different types of different types are used. A production management device that determines the production order of the substrates when continuously producing the substrates, a production information input unit that accepts input of production information including at least information on the type of substrate to be produced, and the production An acquisition unit that acquires data by reading out data of a component supply device that supplies components to a production target substrate input through an information input unit from a storage unit, or an acquisition unit that acquires through the production information input unit, and the acquired component supply device Based on this data, the necessary number of the mounting plates required for arranging all the component supply devices used for the production of the board is determined based on the basis of each product type. The sum of the required number of mounting plates can be installed on the base for the two types of substrates produced in succession, based on the calculating means for calculating each of the above and the required number of mounting plates calculated by the calculating means. And determining means for determining the production order of the substrates so as not to exceed the total number of mounting plates.

The following configuration is preferable as an embodiment of the present invention.
The determining means determines a production order of the substrates so that a substrate of a variety having a large number of necessary mounting plates and a substrate having a small variety are alternately arranged. Such an arrangement can be determined relatively easily, so that the processing burdened by the determining means is light.

  According to the present invention, it is possible to perform the operation of setting the component supply device used for the production of the next type of board on the surface mounter during the production of the current board, so that the operation rate of the board production line can be increased. .

<Embodiment 1>
Embodiment 1 of the present invention will be described with reference to FIGS.
1. Overall Configuration of Substrate Manufacturing Line L FIG. 1 is a diagram showing a partial configuration of a substrate manufacturing line L applied to this embodiment. This board production line L has solder printing equipment (not shown), surface mounters U1 and U2, and reflow equipment R connected in series by a conveyor, and each equipment U1, U2 and R performs printing processing (surface of the board). Solder paste paste processing), component mounting processing (processing to mount chip components such as ICs on the printed circuit board), reflow processing (solder paste is melted at high temperature, components and board on The substrate is manufactured by performing predetermined processing such as processing for electrically connecting the patterns to the substrate.

  Further, reference numeral 300 in FIG. 1 denotes a production management computer that manages the board production line L. In this embodiment, the apparatuses U1, U2, and R constituting the substrate manufacturing line L and the production management computer 300 are electrically connected through a LAN (local area network). The operation status of the devices U1, U2, and R1 can be managed.

2. Configuration of Surface Mounter U As shown in FIG. 1, the surface mounters U1 and U2 include a conveyor 20 that conveys a substrate, a component supply unit 30, a head unit 60, and the like. In the following description, the substrate transport direction (left-right direction in FIGS. 1 and 2) is defined as the X-axis direction, and the Y-axis direction and the Z-axis direction are defined as in FIGS.

  As shown in FIG. 2, the conveyor 20 includes a pair of conveyor belts 21 that are driven to circulate in the X direction, so that the substrate on the upper surface of the belt can be fed in the X axis direction by friction with the belt.

  A transport conveyor 25 is installed upstream of the mounting machine U1, a transport conveyor 27 is installed downstream of the mounting machine U2, and a transport conveyor 26 is installed between the mounting machines U1 and U2. Has been.

  Each of the conveyors 25 to 27 is continuous with the conveyor 20 provided in the mounting machines U1 and U2 without any step, and has a function of relaying the substrate between adjacent apparatuses.

  With such a configuration, the board can be sequentially sent from the solder printing apparatus located on the upstream side (solder printing apparatus → mounting machine U1 → mounting machine U2 → reflow apparatus R).

  Both the substrate carried on the base 11 of the mounting machine U1 through the transport conveyor 25 and the substrate transported onto the base 11 of the mounting machine U2 through the transport conveyor 26 are both at the work position in the center of the base (see FIG. 2 (position indicated by a two-dot chain line in FIG. 2) is stopped by a substrate stopper (not shown).

  In addition, component supply units 30 are provided at four corners on the base 11 of each of the mounting machines U1 and U2. The component supply unit 30 is a place for supplying components to be mounted, and a collective exchange cart D is detachably attached thereto. That is, in this embodiment, a total of four collective exchange carts D1 to D4 are attached to the surface mounter U1, and a total of four collective exchange carts D5 to D8 are attached to the surface mounter U2. Thus, when the two surface implementation machines U1 and U2 are combined, a maximum of eight collective exchange carts D can be used.

  As shown in FIG. 3, each batch exchanging cart (hereinafter simply referred to as a cart) D is provided with a feeder plate 110 (corresponding to the “mounting plate” of the present invention) having a flat plate shape at the front of the cart. The feeder plate 110 has a shape extending in the vertical direction (in the relationship with the surface mounter U in the X-axis direction along the conveying direction of the conveyor 20) in the same figure, and a plurality of feeders F are arranged side by side (in the present invention). Equivalent to “component supply device group”).

  The feeder F is mainly composed of a feeding device 83, a pulling device 87, a feeder main body 81 to which these devices are fixed, and the like, and has a long shape in the Y-axis direction as a whole as shown in FIG.

  Further, at the rear part of the feeder body 81, a component supply tape BP having a sheet shape in which components are held on the upper surface at regular intervals is wound and held on a reel (not shown). The feeder main body 81 is provided with a tape passage 90, and the component supply tape BP fed out from the reel is drawn out to the front of the apparatus while being passed through the tape passage 90.

  From the above, when the delivery device 83 is operated, the sprocket 84 constituting the delivery device 83 rotates and draws the component supply tape BP in the tape passage 90 forward of the device, resulting in the component set at the front end of the device. Components are supplied to the supply position O at regular intervals. Since only one type of component can be supplied by one feeder F, the feeder F is required at least for the types of components to be mounted when the board is produced.

  Next, returning to FIG. 2 and FIG. 3, the head unit 60 for mounting the components supplied through the feeder F on the substrate stopped at the working position and the servo mechanism for driving the head unit 60 will be described. . Since these mechanisms use the same structure for both the mounting machines U1 and U2, here, the mounting machine U1 side will be described as an example.

  A pair of support legs 41 are installed on the base 11. Both support legs 41 are located on both sides of the work position, and both extend straight in the Y direction (the vertical direction in FIG. 2).

  Both support legs 41 are provided with guide rails 42 extending in the Y direction on the upper surfaces of the support legs, and head supports 51 are attached to the left and right guide rails 42 while fitting both ends in the longitudinal direction.

  A Y-axis ball screw 45 extending in the Y direction is attached to the right support leg 41, and a ball nut (not shown) is screwed to the Y-axis ball screw 45. A Y-axis motor 47 is attached to the Y-axis ball screw 45.

  When the motor 47 is energized, the ball nut advances and retreats along the Y-axis ball screw 45. As a result, the head support 51 fixed to the ball nut, and the head unit 60 described below, along the guide rail 42 in the Y direction. (Y-axis servo mechanism).

  The head unit 60 is attached to the head support 51 so as to be movable in the X-axis direction via a guide member (not shown).

  An X-axis ball screw 55 extending in the X direction is attached to the head support 51, and a ball nut is screwed onto the X-axis ball screw 55.

  Thus, when the X-axis motor 57 is energized, the ball nut moves forward and backward along the X-axis ball screw 55, and as a result, the head unit 60 fixed to the ball nut moves in the X direction (X-axis servo mechanism).

  Accordingly, the head unit 60 can be moved and operated in the horizontal direction (XY direction) on the base 11 by controlling the X-axis servo mechanism and the Y-axis servo mechanism in combination.

  A plurality of suction heads 63 that perform a mounting operation are mounted in a row on the head unit 60. The suction head 63 protrudes downward from the lower surface of the head unit 60, and is configured to be able to move up and down with respect to the frame of the head unit 60 by driving a Z-axis motor (Z-axis servo mechanism). And the suction nozzle 63 is provided in the front-end | tip of each suction head 64, and it is comprised so that a negative pressure may be supplied from the negative pressure means outside a figure.

  With such a configuration, by operating each servo mechanism at a predetermined timing, it is possible to take out the component supplied to the component supply position O through the feeder F by the suction head 63, and to remove the removed component. After moving to the component mounting position on the board, it is possible to mount (component mounting processing) at the component mounting position.

  In addition, the code | symbol 17 shown in FIG. 2 is a components recognition camera. The component recognition camera 17 captures an image of the component taken out by the suction head 63 and detects the suction posture of the component.

3. Electrical configuration of apparatus (a) Electrical configuration of surface mounter The entire apparatus of the mounters U1 and U2 is controlled by a controller 210. The controller 210 includes a main control unit 211 configured by a CPU or the like, and further includes a storage unit 212, an axis control unit 215, an image processing unit 216, and a communication unit 217.

  The shaft controller 215 is electrically connected to the shaft motors 47 and 57 and an encoder for detecting the rotation state of the motor, and can control the various shaft motors 47 and 57 through the coaxial controller 215.

  In addition, the component recognition camera 17 and illumination are electrically connected to the image processing unit 216, and an image output from the component recognition camera 17 is captured by the image processing unit 216.

  From the above, by appropriately operating the various shaft motors 47, 57 and the like by the main control unit 211, it is possible to execute the component supply processing through the feeder F and the component mounting processing using the head unit 60.

(B) Electrical Configuration of Production Management Computer The production management computer 300 is configured mainly by a main control unit 310, a program storage unit 320, a storage unit 330, a display unit 350, an input unit 360, and the like. It is connected to the.

  The input unit 360 has a function of accepting input of production information (information on the type of substrate to be produced), and is configured by a touch panel in this example.

  In the storage unit 330, in addition to various data necessary for controlling the apparatus, as shown in FIG. 6, the data of the component B and the corresponding feeder F are stored in association with each other.

  With this configuration, if the type of component to be mounted on the board can be specified, the type of feeder F necessary for supplying the component and the data of the width dimension W of the feeder F can be obtained. Can be done.

  Then, when production information is input through the input unit 360, necessary data is read from the storage unit 330, and the main control unit 310 reads the necessary program from the program storage unit and executes the program in order, thereby the board. The production plan such as the production order is automatically generated.

  Hereinafter, a specific flow of processing executed by the production management computer 300 will be described with reference to a flowchart shown in FIG.

Here, the description will be continued assuming that the following input has been made through the input unit 360 as production information.
(1) Substrate varieties to be continuously produced (variety A to E)
(2) Information on components mounted on each type of board

  When production information is input, in the production management computer 300, the main control unit 310 performs processing for accessing the storage unit 330 and reading the data of the feeder F used for production (S10). The processing function performed by the “acquisition means” of the present invention is realized by the processing of S10 executed by the main control unit 310.

  When the data of the feeder F is read out, next, the arrangement space of the feeder F, and hence the necessary number of carriages necessary for the arrangement of the feeder F (corresponding to the “required number of mounting plates” in the present invention) N is calculated. Processing is performed for each of the varieties A to E (S20). The processing function performed by the “calculation unit” of the present invention is realized by the processing of S20 executed by the main control unit 310.

  The process of S20 will be described with a specific example. When 12 types of components B1 to B12 are mounted on the substrate of the type A, the arrangement space of the feeder F for the type A corresponds to the components B1 to B12. This is a numerical value obtained by adding the widths W1 to W12 of the 12 types of feeders F1 to F12.

  WF = W1 + W2 + ... + W11 + W12 + α

  Note that the above “α” is to allow for a certain amount of gap between the feeders when actually arranged.

  As shown in FIG. 4, the lateral width Wo of the feeder plate 110 provided on the carriage D is determined in advance. Therefore, if the arrangement space WF of the feeder F is divided by the lateral width Wo of the feeder plate 110, the type A The necessary number N of carts for the substrate can be calculated.

  Here, as a result of the calculation, as shown in FIG. 8A, the necessary number N of substrates for the type A board is “6”, the required number N of substrates for the type B substrate is “4”, and the type Assuming that the required number N of C boards is “2”, the required number N of boards of type D is “3”, and the required number N of boards of type E is “5” Continue the explanation.

  When the necessary number N of trolleys is calculated in the above manner, the main control unit 310 then executes a process of rearranging the order of the boards in the order of the required number of trolleys N (S30).

  Thereby, as shown in FIG. 8B, the order of the substrates is rearranged in the order of product type A, product type E, product type B, product type D, product type C.

  After that, the main control unit 310 determines the production order of the substrates so that the types of substrates having a larger required number of carts N and the substrates of a smaller type are alternately arranged (S40).

  Specifically, among all the types A to E, the type of substrate having the largest required number of carts N, that is, the type A substrate is first selected as the substrate to be produced. And the board | substrate of the kind with fewer required trolley | bogies N is selected from the remaining four kinds B-E for the board | substrate produced next. Thereby, the substrate of the product type C is selected following the product type A.

  And the board | substrate of the kind with many more required trolley | bogies N among the remaining three kinds B, D, and E is selected for the board | substrate produced following the kind A and the kind C. As a result, following the types A and C, the substrate of the type E is selected.

  As a result of substrate selection according to the above rules, as shown in FIG. 8C, the board production order is determined in the order of product type A → product type C → product type E → product type D → product type B. As a result of determining the board production order in this way, in this example, the sum of the necessary number of carriages (necessary number of mounting plates) N can be installed on the base 11 for two types of boards produced in succession. The total number of carts (the total number of carts that can be used, which is eight in this example) is not exceeded.

  Specifically, since the necessary number N of types A is “6” and the required number N of types C is “2”, the required number N of types A and the required number N of types C are N. The sum is “8”, which is a setting that does not exceed the total number of vehicles that can be installed “8”.

  In addition, since the required number N of vehicles for the product type E is “5”, the sum of the required number of vehicles N for the product type C and the required number of vehicles N of the product type E is “7”, and the total number of vehicles that can be installed is “8”. The setting does not exceed. Since the required number N of types D is “3”, the sum of the required number N of types E and the required number N of types D is “8”, and the total number of vehicles that can be installed is “8”. The setting does not exceed "".

  The processing function performed by the “determination unit” of the present invention is realized by the processing of S40 executed by the main control unit 310.

  When the board production order is determined, the main control unit 310 then selects one board according to the production order (S50), and which cart D is selected so that the component mounting process can be executed most efficiently. The feeder allocation to determine which feeder F is to be arranged is determined, and further, the mounting order of components is determined (optimization process, S60).

  As a result, in this example, among all the eight trucks D1 to D8 installed in the mounting machines U1 and U2, as shown in FIG. 9, the truck D1 to the truck D3 of the mounting machine U1 and the mounting machine U2 The feeder F used when producing the board | substrate of the kind A is allocated to a total of six trolley | bogies of the trolley | bogies D5-D7.

  When the optimization process is completed for the substrate of type A, the main control unit 310 executes the processes of S70 and S80. As a result of the YES determination in the process of S70 and the NO determination in the process of S80, the process proceeds to S90.

  In S90, a process of excluding the cart D assigned for the board that has undergone the optimization process in S60 from the optimization process target is performed. Therefore, here, a total of six carriages, that is, the carriage D1 to the carriage D3 of the mounting machine U1 and the carriages D5 to D7 of the mounting machine U2 are excluded from the target of the optimization process.

  Thereafter, the process proceeds to S100. In S100, the main controller 310 performs processing for selecting the next substrate in accordance with the production order. By this processing, the substrate of the type C is selected in this example.

  Subsequent processing is as described above, and in S60, optimization processing is performed, that is, allocation of feeders F is determined for the cart 4 of the mounting machine U1 and the cart D8 of the mounting machine U2 that are not excluded. The component mounting order is determined.

  When the optimization process is completed for the substrate of type C, the main control unit 310 executes the processes of S70 and S80. As a result of the YES determination in the process of S70 and the NO determination in the process of S80, the process proceeds to S90.

  In S90, a process of excluding the cart D allocated for the board for which the optimization process of S60 has been completed from the optimization process target is performed. Therefore, here, the two carts, the cart D4 of the mounting machine U1 and the cart D8 of the mounting machine U2, are excluded from the optimization processing target, and the other carts are the target of the optimization processing.

  Thereafter, the process proceeds to S100. In S100, the main controller 310 performs processing for selecting the next substrate in accordance with the production order. In this example, the substrate of the type E is selected by this processing, and then the optimization processing is performed on the substrate of the type E in S60.

  When the process for optimizing the substrates of all types A, C, E, D, and B is completed, a YES determination is made in S80, and the series of processes ends.

  Thereafter, the operator performs a setup operation for the type A to be produced first. That is, an operation of setting the feeder F to the cart D1 to the cart D3 and the cart D5 to the cart D7 is first performed, and subsequently, the cart D1 to the cart D3 on which the feeder F is set are connected to each component supply unit of the mounting machine U1. 30 and the work which attaches the trolley | bogie D5 to which the feeder F was set to the trolley | bogie D7 to the components supply part 30 of the mounting machine U2 is performed.

  Thus, when the set-up operation for the type A to be produced first is completed, under the control of the production management computer 300, each device constituting the board production line L, that is, a solder printing device, surface mounters U1, U2, The reflow apparatus R is operated, and the production of the substrate of the type A is advanced.

  Since the cart D4 of the surface mounter U1 and the cart 8 of the surface mounter U2 are not used for production during the production of the substrate of the kind A, both carts D4 and D8 are surface mounted as shown in FIGS. Even if it is removed from the machines U1 and U2, production will not be hindered.

  Therefore, the operation of removing the two carts D4 and D8 from the surface mounters U1 and U2 and setting the feeder F to be used for the next product C to be produced on the cart can be performed simultaneously with the production of the product A. I can do it.

  And if the feeder F can be set to both carts D4 and D8, then, if both carts D4 and D8 that have been set are attached to the component supply units 30 of the surface mounters U1 and U2, respectively, After the production of A is completed, the substrate of the type C can be produced continuously without taking time. In other words, it is not necessary to perform the setup change work for exchanging the carriage while the board production line L is temporarily stopped.

  During production of the substrate of the type C, since the carriages D1 to D3 of the surface mounting machine U1 and the carriages D5 to D7 of the surface mounting machine U2 are not used for production, as shown in FIGS. 9 and 11, each carriage D1 Even if ˜D3 and D5 to D7 are removed from both surface mounters U1 and U2, production will not be hindered.

  Therefore, the operation of removing the carts D1 to D3 and D5 to D7 from the surface mounters U1 and U2 and setting the feeder F to be used for the next production type E to the cart simultaneously with the production of the product C substrate. Can proceed.

  And if the feeder F used for the production | generation type E scheduled to be produced next can be set to each trolley D1-D3, D5-D7, after that, each trolley D1-D3, D5-D7 which set was completed. If it is attached to the component supply unit 30 of the surface mounters U1 and U2, after the production of the product C is completed, the substrate of the product E can be continuously produced without taking time.

  As described above, according to the present embodiment, the setup work for setting the feeder F used for the production of the next product to the surface mounter U can be performed during the production of the current board. The operating rate can be increased.

  Next, as shown in FIG. 12, the required number of carts N is “6” for the product A, “4” for the product B, “2” for the product C, “4” for the product D, The case where the type E is “5”, that is, the case where the required number N of types D of the type D is one more than the example of FIG. 8 will be described.

  Also in this case, as a result of the processing of S10 to S40 being performed in order by the production management computer, the production order of the substrates is as shown in FIG. → It will be determined as breed B.

  When the board of the product type E is produced, as shown in FIG. 13, the car D1, the car 2, the car D3, the car D6, and the car D7 are in operation, and the other three cars D4, D5, and D8 are of the product E. Not used for production. Therefore, as shown in FIG. 14, these three carriages D4, D5, and D8 can be removed from the surface mounters U1 and U2 to proceed with the setup work of the feeder F used for the product type D produced by the next product type substrate. .

  Here, the number of carts that can proceed with the set-up work is “3” of D4, D5, and D8, whereas the number of carts required for the product type D produced by the next product board is also shown in FIG. As it is, it is “4 units”.

  In this way, when the number of trolleys capable of proceeding with the required number of trolleys N is insufficient, it is not possible to finish the setup of the board produced by the next-generation board during the production of the board. After completing the production of the product type E, it is necessary to temporarily stop the substrate transfer line L and perform the setup work (cart replacement work).

  However, even in this case, with the conventional configuration, it is necessary to stop the substrate transfer line L and perform the exchanging work for four carriages. If the order is decided, the setup work can be completed during the production of the board among the four trucks, so that the setup work performed by stopping the substrate transfer line L is only for one truck. This is all you need to do. Therefore, even in such a case, the operating rate of the substrate production line L can be increased as compared with the conventional one.

  As described above, in the case where the required number of trolleys N is less than the number of trolleys that can be used for setup work, the optimization is successful in S70 because the feeder F cannot be placed on the trolley D when the optimization process is performed. Is determined by the main control unit 310 when the determination process is performed.

  As a result, the process goes through the loop (1) shown in FIG. 7, and a process of temporarily releasing the carriage that is scheduled to be used is performed (S110, S120). As a result, the number of carts that can be used for the setup work is increased. As a result, the shortage of carts is solved, and the optimization process can be completed also in the above case.

  In addition, in the case of NO determination in the determination processing of S110 (case where optimization is not possible even after canceling the use schedule of all carts), error output is performed such as notifying / displaying an abnormality, and then processing is performed. finish.

  (1) In the above embodiment, a two-connection type line configuration in which two surface mounters U1 and U2 are connected in series has been exemplified, but the number of connection of surface mounters U is not limited to two connections. Three or more connections may be used. Furthermore, the present invention can be applied to a line configuration using a single surface mounter U.

  Further, in this embodiment, an example in which the production management computer 300 is provided exclusively is shown. However, for example, if only one surface mounter U is used, the processing function of the production management computer 300 of this embodiment is surface mounted. It is also possible to abolish the production management computer 300 itself by loading all into the machine U.

  (2) In the above embodiment, a batch exchanging cart is exemplified as means for attaching the feeder F to the component supply unit 30 of the surface mounter U. However, a feeder group in which a plurality of feeders F are arranged side by side is used as the component supply unit 30. As long as it has a structure that can be attached and detached collectively, a plate that is long in one direction may be used.

  (3) In the above-described embodiment, the sum of the required number of carts N for two types of boards produced in succession is set so as not to exceed the total number of carts that can be installed on the base (eight in the above example). However, the production order of the substrates is realized by alternately arranging the substrates of the larger types and the substrates of the smaller types with the necessary number N of carts.

  However, the production order of the boards can be set so that the sum of the required number of carriages N does not exceed the total number of carriages that can be installed on the base for the two types of boards produced in succession. For example, the number of trolleys corresponding to the difference between the required number of trolleys N and the total number of trolleys required for the production of the current board is calculated first, and then a board of a type having a smaller number of necessary trolleys N is then calculated. For example, a method of determining a substrate to be produced may be used.
