[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a component supply method and apparatus for providing components for various operations, and a component mounting apparatus that mounts components on a mounting target using the same, for example, by mounting various electronic components on a circuit board. It is used for supplying electronic components in the case of manufacturing an electronic circuit board, and for manufacturing an electronic circuit board using the same.
[0002]
[Prior art]
By the way, recently, as typified by mobile phones, products have been miniaturized. As a result, the size of the electronic circuit board has become smaller, and the size of the electronic component itself has been reduced to accommodate the high-density mounting. The opportunity to mount such a large electronic component on a circuit board is increasing.
[0003]
Such a large-sized electronic component is accommodated in a tray in a planar arrangement so that a large number can be stably supplied while handling a large number of the components in a low bulk. In recent years, large-sized products have advanced multi-functionality, and it is necessary to mount various types of electronic components on one circuit board. It is desired to be able to supply various kinds of electronic components in the same component mounting apparatus as required at each time by having to cope with a production system.
[0004]
To cope with this, conventionally, a large number of trays containing different types of electronic parts are arranged and stored in one tray storage unit, and the tray containing the necessary electronic parts can be pulled out and supplied at each time. ing.
[0005]
FIG. 4 shows an example of such a conventional device. In this apparatus, an empty tray can be disposed of outside the apparatus while supplying various kinds of tray components as described above.
[0006]
To explain this, as shown in FIG. 4, a tray a storing electronic components is stored in multiple stages in a tray storage portion c which is supported by a support plate b and moves up and down. The tray storage section c is moved up and down by an elevating mechanism e so that each support plate b or its storage section appropriately corresponds to the height of the component supply section d, and the storage section of the component supply section d and the tray storage section c corresponding thereto. The support plate b is taken in and out by the take-out mechanism p between them, and each time the support plate b is pulled out, the electronic components in the tray a supported by the support plate b are supplied to the component handling mechanism f and used for handling. The component handling mechanism f has a mounting head i that is moved by moving axes g and h in the orthogonal XY2 directions, and the suction nozzle j mounted on the mounting head i (in FIG. 4, stands by at a tool exchange station k). In step (1), the supplied electronic component is picked up, carried to the component mounting section m, and mounted on a predetermined position of the circuit board n positioned there. By repeating the above, predetermined electronic components are mounted on the circuit board n to manufacture an electronic circuit board.
[0007]
When the tray a becomes empty due to the supply of electronic components in the component supply unit d, the component handling mechanism f temporarily replaces the suction nozzle j of the mounting head i with the tray suction pad o as shown in FIG. This is performed at the tool exchange station k. Next, the empty tray a above the support plate b at the component supply position is sucked and lifted by the replaced tray suction pad o. In this state, the support plate b is stored in the corresponding storage section of the tray storage section c by the loading / unloading mechanism p. At this time, the upper and lower passages q in the component supply section d are opened by the retraction of the loading / unloading mechanism p due to the storage of the support plate b, so that the empty tray a lifted by the tray suction pad o is removed from the upper and lower passages q. The waste tray r is discharged through the opened upper and lower passages q onto the waste conveyer r below, and the discharged tray a is discarded out of the apparatus from the waste window s by driving the waste conveyer r.
[0008]
[Problems to be solved by the invention]
However, in the above-described conventional apparatus, the waste conveyor r extending from below the component supply unit d to the outside of the apparatus has a structure that vertically overlaps the component supply unit d in two stages, so that a complicated, expensive, and large-sized device with a high mechanism density is provided. become. Further, the operation of discharging the empty tray a from the component supply unit d for disposal is performed during the component mounting sequence operation in which various electronic components supplied by the component handling mechanism f are repeatedly mounted on the circuit board n. Since the component mounting operation is interrupted each time an empty tray h is discharged, the work efficiency of component mounting is reduced. In addition, each time the mounting head i discharges an empty tray a, and each time when the mounting head i finishes discharging and returns to the component mounting operation, the suction nozzle j moves to the tray suction pad o, and the tray suction pad o moves to the suction nozzle j. In the case of replacement, the loss time becomes longer, which also lowers the work efficiency.
[0009]
SUMMARY OF THE INVENTION An object of the present invention is to provide a component supply method and apparatus which can reduce the size of the apparatus simply and at low cost, improve the efficiency of repetitive work by sequentially using parts to be supplied as needed, and parts using these. A mounting device is provided.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, in the component supply method of the present invention, a tray storing components is supported by a support plate and stored in a tray storage portion that moves up and down, and each support plate or the storage portion is appropriately stored. Each time the support plate is pulled out, the parts in the tray supported by it are supplied to the parts handling mechanism and the parts are When the tray is emptied at the component supply position, the tray is emptied from the support plate by the component handling mechanism to recycle the tray. Repeating this process, the parts stored in each tray in the tray storage section can be supplied as needed, and the tray storage section can be used together with the support plate and the disposal plate. When the tray is emptied at the component supply position and the empty tray is once lifted up by the component handling mechanism, the disposal plate is pulled out according to the height of the component supply position, After discharging the empty tray that is lifted by the component transfer mechanism onto the pulled-out discard plate, the discard plate receiving this tray is stored again in the tray storage unit, and this is referred to as the component supply position. One of the features is that the discharge tray is disposed outside the disc tray on the disc tray at a tray discard position set separately.
[0011]
As a result, a large number of trays are supported by the support plate and stored in the tray storage section so that they can be individually put in and taken out of the tray storage section. A tray containing necessary components is drawn out to the component supply position together with the support plate each time and supplied. Then, while repeatedly performing various types of component handling by the component handling mechanism, the empty tray at the component supply position is ejected and discarded at the component supply position. By lifting and storing the support plate in the drawn-out state in the tray storage section, the discard plate stored so that it can be taken in and out together with the support plate in the tray storage section can be pulled out to the component supply position without disturbing the support plate. . The component handling mechanism ejects the empty tray once lifted onto the drawn-out discard plate so that the new tray containing the components can be stored in place of the empty tray. Is stored in the tray storage portion again, so that the tray required next to the component supply position is not obstructed from being pulled out together with the support tray. The disposal tray stored in the tray storage together with the empty tray is disposed outside from the tray storage when located at the tray disposal position, so that the next empty tray can be stored and disposed.
[0012]
Therefore, while the components stored in the many trays stored in the tray storage unit are supplied to the component supply position according to the needs at each time and subjected to various kinds of handling, the tray emptied at the component supply position is removed. Discharge from the normal handling path for component supply and disposal to the outside can be performed through the component supply position and the tray storage unit, and there is no need for special equipment or space for this purpose. Cost reduction can be achieved.
[0013]
As a component supply device that realizes this, a tray storage unit that supports a tray that stores components by a support plate and stores the tray so that it can be individually taken in and out, a lifting mechanism that moves up and down the tray storage unit, and a tray that is raised and lowered Each support plate in the storage unit or a component supply unit provided so as to correspond to the storage unit at a predetermined height, and the support plate is put in and out between the component supply unit and the storage unit of the corresponding tray storage unit. And a loading / unloading mechanism for supplying the components contained in the tray on the drawn-out support plate to a component handling mechanism for handling the components in various ways, and for handling the components. The discard plate, which is stored so that it can be separately taken in and out together with the plate, and the disc tray that is set separately from the And a tray discarding unit that discards plate is positioned, it is sufficient Sonaere a discard mechanism for discarding the trays supported on the disposal plate located in the tray waste portion from the waste plate on the outside of the apparatus.
[0014]
However, when the tray is emptied in the component supply unit, the empty tray is once lifted by the component handling mechanism, and the discarding plate is raised to the height of the component supply position by raising and lowering the tray storage unit by the lifting mechanism. The parts handling mechanism ejects the empty tray that was once lifted onto the discarded waste plate, and then the discard plate that received the ejected tray is stored again by the eject mechanism. Control means for controlling the discharge tray to be discarded from above the discard plate to the outside of the apparatus by the discard mechanism by ascending and descending the tray storage section by the elevating mechanism so as to correspond to the tray discarding section. is necessary.
[0015]
When the parts handling mechanism transfers the parts supplied by the parts supply unit to a work machine that repeatedly uses various parts in sequence and supplies them, and supplies them to the work machines, the parts supply operation is started. The operation of discharging the empty tray and discarding it outside can be performed outside the cycle of the repetitive work in which the supplied parts are used, so that it is possible to avoid a decrease in the efficiency of the repetitive work in which the parts are used.
[0016]
If the component handling mechanism is provided with a component handling tool that holds and handles components supplied in the component supply unit and a tray handling tool that holds and handles empty trays in the component supply unit, component handling While the mechanism handles various parts supplied by the parts handling tool, when empty trays are ejected for disposal, it can be done instantly simply by selecting and using the tray handling tool. The time loss due to the two tool changes has been eliminated and the work efficiency has been improved, and the component supply interval between the operations of discharging the empty tray has no effect on the cycle interval of the repetitive operation in the working machine using the components. It is also advantageous to set a short time interval.
[0017]
Such a component supply device is provided with a component mounting mechanism for mounting a supplied component to a mounting target, and a component handling mechanism holds and handles the component supplied by the component supply unit and transfers the component to the component mounting mechanism. When mounted on a mounting target and provided for mounting on a mounting target, it is provided as a component mounting apparatus having various characteristics as described above, and sequentially mounting necessary components on the mounting target each time to finish a predetermined product. be able to.
[0018]

[0025]
Further, the empty tray 2 once lifted by the component handling mechanism 6 onto the drawn-out disposal plate 7 is discharged as shown by a solid line in FIG. A new tray 2 can be stored in place of the empty tray 2. The discard plate 7 receiving the discharged tray 2 is stored again in the tray storage section 4 as indicated by the phantom line in FIG. You can keep it from being pulled out.
[0026]
The disposal plate 7 stored in the tray storage unit 4 together with the empty tray 2 is disposed outside from the tray storage unit 4 when located in the tray disposal unit 8, so that the next empty tray 2 can be stored and disposed. it can.
[0027]
Therefore, the electronic components 1 accommodated in the large number of trays 2 accommodated in the tray accommodating unit 4 are supplied to the component supplying unit 5 according to the needs at each time, and are used for various kinds of handling. The empty tray 2 is discharged through the component supply unit 5 and the tray storage unit to be discharged from the component supply unit and the tray storage unit, which are the normal handling paths for component supply, and discarded to the outside. No additional equipment or space is required, and the apparatus can be simplified and the cost can be reduced.
[0028]
In order to realize this, when the tray 2 is emptied by the component supply unit 5, the component supply device according to the present embodiment lifts the empty tray 2 by the component handling mechanism 6 and simultaneously raises and lowers the elevator mechanism 11. The discarding plate 7 is pulled out by the loading / unloading mechanism 12 in accordance with the height of the component supply unit 5 when the tray storage unit 4 is moved up and down, and the component handling mechanism 6 is once lifted on the pulled out discarding plate 7. After the empty tray 2 is discharged, the discard plate 7 receiving the discharged tray 2 is stored again in the tray storage unit 4 by the loading / unloading mechanism 12, and this is moved up and down by the lifting mechanism 11 to move the tray storage unit 4 up and down. Corresponding to the tray discarding section 8, a controller 16 for controlling the discarding tray 2 to discard the ejection tray 2 from above the discarding plate 7 to the outside of the apparatus by a discarding mechanism 15 is provided. It is possible to stably achieve the supply method according to a predetermined program. The controller 16 can employ various control circuits such as a CPU.
[0029]
In the present embodiment, the component handling mechanism 6 transfers and supplies the electronic components 1 supplied by the component supply unit 5 to a component mounting mechanism 21 as a working machine that repeatedly uses various electronic components 1 to work repeatedly. Then, the work is performed by the component mounting mechanism 21. Accordingly, the operation of discharging the empty tray 2 during the component supply operation and discarding the tray outside can be performed outside the cycle of the repetitive work in which the supplied electronic component 1 is used, so that the efficiency of the repetitive work in which the electronic component 1 is used is improved. It is possible to avoid lowering.
[0030]
The component mounting mechanism 21 manufactures an electronic circuit board by mounting the electronic component 1 transferred to the transfer table 22 in the component transfer section 20 by the component handling mechanism 6 to manufacture an electronic circuit board. A single component mounting device is combined with the device, and has a mounting head 25 equipped with a large number of component handling tools 23 for mounting the transferred electronic component 1. The component handling tool 23 is a suction nozzle in the illustrated embodiment, but may be another holding type such as a chuck.
[0031]
The mounting head 25 intermittently rotates by the arrangement pitch of the component handling tools 23, and holds the electronic component 1 transferred thereon whenever one component handling tool 23 reaches and stops at the transfer table 22. The electronic circuit board is manufactured by repeatedly picking up and carrying it to the component mounting section 26 and mounting it on the circuit board 24 positioned by the XY table 27 or the like that moves in the orthogonal XY2 directions.
[0032]
Using the positions where the component handling tool 23 temporarily stops on the way from the component transfer unit 20 to the component mounting unit 26, the suction posture and the suction state of the electronic component 1 picked up and carried. Various kinds of auxiliary work required before mounting the electronic component 1 on the circuit board 24, such as inspection of the electronic component 1 and rotation of the component handling tool 23 for correcting the suction posture of the electronic component 1, are performed. In addition, by utilizing each position where the component handling tool 23 temporarily stops while returning from the component mounting unit 26 to the component transfer unit 20, discarding of a defective product not mounted in the component mounting unit 26, a component handling tool Is necessary to pick up the next electronic component 1 and carry it, such as selecting the component handling tool 23 according to the type of the electronic component 1 to be picked up by the component transfer section 20 and performing an appropriate inspection. Perform various auxiliary tasks.
[0033]
The tray storage section 4 has a box shape and has an access port 4b opened on one side. Through this access port 4b, the support plate 3 alone or the tray 2 while being supported, and the tray plate 7 alone or empty. The loading and unloading with the tray 2 received is performed. However, pulling out of the discard plate 7 having received the empty tray 2 is not actually performed.
[0034]
The tray accommodating section 4 is provided in the main body 31 of the component supply device so as to be supported by the elevating table 32 of the elevating mechanism 11 so as to be able to move up and down. A part 5 is provided. The tray discarding section 8 is set at the lowest position in the main body 31, and the discarding mechanism 15 is installed there.
[0035]
The elevating mechanism 11 guides the elevating table 32 by two guides 33, and rotates the screw shaft 34 forward and reverse by the motor 35, thereby ascending and descending with the tray storage unit 4. When the tray storage unit 4 is supported so as to be detachable from the elevating table 32, the type of the electronic component 1 can be changed and resupplied by exchanging the single unit. In order to supply the electronic components 1 to the tray storage section 4 taken out after use, the empty tray 2 has already been discarded and is not left. Therefore, the new tray 2 containing the electronic components 1 is replaced with the empty support plate 3. , And can be stored automatically or manually.
[0036]
However, even if the tray storage unit 4 cannot be removed from the elevating table 32, if necessary, another insertion port is provided in a direction different from the entrance 4b so that the tray 2 can be automatically operated even during component supply or when component supply is stopped. Or can be replenished manually.
[0037]
The component supply unit 5 is a table type, and corresponds to a plate opening (not shown) of the main body 31, and includes a guide rail 41 that guides the support plate 3 and the disposal plate 7 into and out through the plate opening and out, and the insertion / extraction mechanism 12. Equipped. The loading / unloading mechanism 12 includes a loading / unloading body 43 having an engaging portion (not shown) that engages with a gripping engaging portion 42 provided on the support plate 3 or the disposal plate 7 as shown in FIG. , And a motor 45 that drives the drive belt 44 forward and reverse to move the plates 3 and 7 into and out of the loading and unloading body 43.
[0038]
The component handling mechanism 6 has a transfer head 47 that is reciprocated by the Y axis 48 between the component supply unit 5 and the component transfer unit 20. The transfer head 47 includes the component handling tool 13 and the tray handling tool 14. Equipped with both. Thus, when the component handling mechanism 6 handles the electronic component 1 supplied by the component handling tool 13 in various ways, the tray handling tool 14 is selectively used when the empty tray 2 is discharged for disposal. Can be done instantaneously, eliminating the time loss due to the two required tool changes, improving work efficiency, and setting the component supply interval between the operations of discharging the empty tray 2 to the component using the electronic component 1. This is advantageous for setting a shorter time interval that does not affect the cycle interval of the repetitive work in the mounting mechanism 21 or the like.
[0039]
The component handling tool 13 shown in FIG. 1 is a suction nozzle 13a, and the tray handling tool 14 is a tray suction pad 14a. However, the present invention is not limited to this. be able to. A plurality of suction nozzles 13a are radially attached to a rotating body 47a supported by the transfer head 47, and the rotation of the rotating body 47a allows the suction nozzle 13a to be switched to a turret type depending on the type of electronic component 1 to be handled.
[0040]
As shown in FIG. 2, the discarding mechanism 15 supports a pusher 51 having a plurality of rake-shaped pushing pieces 51 a so as to be able to advance and retreat with a guide 52 and a screw shaft 53. , The pusher 51 can be pushed backward and pulled out forward. Correspondingly, a plurality of escape windows 7a on the disposal plate 7 from which the plurality of pushing pieces 51a of the pusher 51 are pulled out from below as shown in FIG. 2 to prevent the tray 2 from falling off. The width and the pitch are provided so as to cover the advance / retreat range of the pushing piece 51a.
[0041]
As a result, the discard plate 7 receives the empty tray 2 as indicated by the phantom line in FIG. 2 and is stored in the tray storage unit 4, and is moved to the position of the tray discard unit 8 as illustrated in FIG. 2. At this time, the pushing piece 51a penetrates through the escape window 7a of the discard plate 7 and projects upward through the opening 4c shown in FIG. In this state, when the motor 54 rotates forward and the pusher 51 advances, the empty tray 2 on which the discard plate 7 is received is discarded from the discard window 55 of the main body 31 to the outside of the apparatus. After being discarded, the motor 54 rotates reversely and returns the pusher 51 to its original position.
[0042]
However, since the specific configuration of each mechanism can be changed in various ways, it is not limited to the present embodiment and the specific structure shown.
[0043]
A specific control example of the supply state of the electronic components 1 including the discharge and disposal of the empty tray 2 under the control of the controller 16 will be described with reference to the main operation control flowchart shown in FIG. As shown in FIG. 3, the normal operation of component transfer in which the electronic components 1 are sequentially supplied and transferred to the component mounting mechanism 21 is performed until the transfer is completed unless an empty tray 2 is generated in the component supply unit 5. You can continue.
[0044]
When a partially empty tray 2 occurs, a tray discharging operation is temporarily performed. In this tray discharge operation, first, the empty tray 2 is sucked and held, the support plate 3 is stored in the tray storage unit 4, the discard plate 7 is pulled out of the tray storage unit 4, and the drawn discard plate 7 is pulled out. Then, the empty tray 2 held above is discharged.
[0045]
Subsequently, the discard plate 7 having received the empty tray 2 is stored in the tray storage section 4, and the process is terminated.
[0046]
Thereafter, the operation shifts to the operation of discarding the empty tray 2. This discarding operation is performed by moving the discarding plate 7 receiving the empty tray 2 stored in the tray storage unit 4 to the tray discarding unit 8, and then discarding the tray outside the apparatus by the tray discarding unit 8. .
[0047]
However, the discarding operation does not need to be performed immediately after the discharging operation, and can be performed at an appropriate timing while continuing the component transfer operation after the discharging operation. This timing is performed in accordance with a time lag caused by various causes, such as a time lag required for preparation for mounting components on the next circuit board 24 after component mounting on one circuit board 24 is completed by the component mounting mechanism 21. By doing so, it is possible to take sufficient time to execute the program without affecting others. In some cases, a new tray 2 can be replenished to the tray storage unit 4. According to such a disposal specification, if a plurality of disposal plates 7 are stored in the tray storage unit 4, a problem occurs when another tray 2 becomes empty during standby until the empty tray 2 is disposed. I can respond without.
[0048]
【The invention's effect】
According to the present invention, components stored in a large number of trays stored in the tray storage portion are supplied to the component supply position according to the needs at each time and are subjected to various kinds of handling, and are emptied at the component supply position. The waste tray can be discharged from the normal handling path for component supply and discarded to the outside through the component supply position and the tray storage unit. Simplification and cost reduction can be achieved.
[0049]
In addition, since the operation of discharging the empty tray and disposing of the empty tray during the component supply operation can be performed outside the cycle of the repetitive operation using the supplied component, the efficiency of the repetitive operation using the component may be reduced. Can be avoided.
[0050]
Furthermore, while the component handling mechanism handles various parts supplied by the component handling tool, when empty trays are ejected for disposal, it can be done instantly simply by selecting and using the tray handling tool. This eliminates the time loss due to the two tool changes that were required in the past, improves work efficiency, and affects the component supply interval between operations for discharging empty trays to the cycle interval of repetitive operations in a work machine that uses components. No, it is advantageous to set a shorter time interval.
