Detailed ways

A supply rack according to one aspect of the present disclosure is used for supplying to a manufacturing apparatus a first component storage that accommodates a plurality of components used in the manufacturing apparatus that performs a predetermined operation on a substrate. The supply rack includes: a first storage unit capable of storing a plurality of the first component storage units; a supply unit capable of holding a plurality of the first component storage units and supplying the held first component storage units to all of the first component storage units. the outside of the supply rack; and a moving unit that takes out one or more first component storages that need to be supplied to the manufacturing apparatus next from the plurality of first component storages stored in the first storage unit. device and move to the supply section.

Thereby, the supply rack can automatically prepare one or more first component storages to be supplied from among the plurality of first component storages, so when supplying the first component storages to the manufacturing apparatus, only the components held in the supply part It is sufficient to supply the 1st parts storage. In other words, when supplying the first components storage to the manufacturing apparatus, it is not necessary to select one or more first components storages to be supplied from among the plurality of first components storages. Therefore, the first component storage can be efficiently supplied to the manufacturing apparatus by the supply rack.

In addition, for example, the supply rack may further include a control unit that controls the moving unit so that when transferring one or more of the first component storage devices to the manufacturing apparatus, Before the supply device is connected to the supply rack, one or more of the first component storages are moved from the first storage unit to the supply unit.

Therefore, before the supply device is connected to the supply rack, in other words, one or more first component storages that need to be supplied can be prepared in advance, so the first component storage can be more efficiently supplied to the manufacturing apparatus through the supply rack.

In addition, for example, when the supply unit holds two or more of the first component storages in a state in which the supply device is connected to the supply rack, two or more of the first component storages may be placed. 1 part container is supplied together to the supply device.

Therefore, since one or more first component storage containers can be supplied to the supply device in a short time, the first component storage containers can be efficiently supplied to the supply device by the supply rack.

In addition, for example, the supply device may have a plurality of first holding portions capable of holding the first component storage or a second component storage that does not store components, and the supply unit may have a plurality of a plurality of second holding parts, the plurality of second holding parts correspond to the plurality of first holding parts, and the second holding parts can hold more than one of the first component storage devices, the control part, The moving part is controlled so that one or more of the first component storages are moved to one or more of the second holding parts among the plurality of second holding parts One or more second holding parts corresponding to one or more first holding parts that do not hold the first component storage device or the second component storage device.

Therefore, even when the supply device holds the second components storage, the supply rack can supply one or more first components storages to the supply device without moving the position of the second components storage.

In addition, for example, the supply rack may further include a recovery unit, and the recovery unit may hold one or more of the plurality of first holding units in a state where the supply device is connected to the supply rack. The second component storage is collected together.

Therefore, since one or more second component storage containers can be collectively collected, the supply rack can efficiently perform the collection operation compared to the case where one or more second component storage containers are sequentially collected.

In addition, for example, the supply rack may further include a loading unit for temporarily placing the one or more second component storages recovered by the recovery unit, and the control unit may control the recovery unit and the recovery unit. The supply unit controls so that at least a part of the recovery operation in which the recovery unit recovers one or more of the first holding units from the plurality of first holding units is performed in parallel with at least a part of the supply operation. 2. An operation in which the parts container then moves to the loading unit, and the supply operation is from when the supply unit starts moving to the plurality of first holding units until supplying one or more components to the plurality of first holding units. The operation of the first component storage device.

Therefore, the supply operation of supplying the first parts storage device to the supply device and part of the collection operation of collecting the second parts storage device into the supply rack are performed in parallel, so that the supply operation and the collection operation can be efficiently performed by the supply rack. both sides.

In addition, for example, the supply rack may further include a second storage unit capable of storing a plurality of the second component storage units, and the control unit may control the recovery unit so that The one or more second component storages placed on the loading unit are rearranged and moved to the second storage unit.

Therefore, the second components storage can be efficiently stored by rearranging the second components storage without gaps in the second storage unit.

Furthermore, for example, the second storage unit may be located above the first storage unit.

Accordingly, a supply rack in which the second storage unit is located above the first storage unit can be realized.

In addition, for example, the supply rack may include a plurality of the second storage units.

Therefore, since more second component storages can be stored compared to the case where there is one second storage unit, the supply rack can reduce, for example, the number of times a worker collects the second component storages.

In addition, for example, the control unit may control the collection unit so that the largest number of the second component storage units are stored in one of the plurality of second storage units. In another embodiment, the second component storage is preferentially moved to the one second storage unit compared to other second storage units among the plurality of second storage units.

Therefore, the second component storage can be stored efficiently.

In addition, for example, the supply rack may further include a connection portion connected to the supply device, the connection portion is located at one end side of the supply rack, and the first storage portion is located at the one end side. side opposite to the other end.

Therefore, when the supply device can autonomously supply the first component storage to the manufacturing device, it is possible to separate the automation area from the area where workers are present, thereby improving safety.

In addition, for example, each of the plurality of first component storages may have a label storing first component information indicating the type of component to be stored, and the supply rack may further include a reading unit, The device is for obtaining the first component information from the label of each of the plurality of first component storages stored in the first storage unit.

Therefore, the supply rack can easily obtain the first component information of the first component storage from the label.

In addition, for example, the supply rack may further include an obtaining unit that obtains second component information indicating components that need to be supplied to the manufacturing device from a management device that manages the manufacturing device. The moving part takes out one or more of the first parts storages from the first storage part based on the first parts information and the second parts information, and transfers them to the supply part according to the type of parts.

Therefore, the supply rack can prepare one or more first component storage devices by using the second component information from the management device.

In addition, for example, there may be a plurality of manufacturing apparatuses to be supplied to the first component storage by the supply rack, and the second component information may include information indicating that the supply needs to be supplied to a plurality of the manufacturing apparatuses. For information on the type of each component in the manufacturing apparatus, the moving unit moves one or more of the first component storages to the supply unit so that the one or more first component storages are aligned toward A sequence in which a plurality of the manufacturing apparatuses are supplied to the first component storage device.

Therefore, it is not necessary to rearrange one or more first component storages in the supply device, so that one or more first component storages can be supplied to the component mounting device in a shorter time.

In addition, for example, the supply rack may further include a notification unit configured to notify the first component storage unit when the number of the first component storage containers stored in the first storage unit is equal to or smaller than a predetermined number. Notifying that the number of the first component storages in one storage unit is less than or equal to the predetermined number.

Therefore, it is possible to suppress the shortage of components of the first components storage in the first storage unit.

Furthermore, for example, the supply rack may include a plurality of the first storage units.

Therefore, since more first component storages can be stored than when there is one first storage unit, the supply rack can reduce the number of times a worker supplies the first component storage unit to the first storage unit.

In addition, a production system according to an aspect of the present disclosure includes: the above-mentioned supply rack; device supply.

Therefore, the same effect as that of the above-mentioned supply rack can be exhibited.

In addition, for example, the production system may further include a supply device to which one or more first component storage containers are supplied from the supply unit, and the supply device may supply one or more The first component storage device is transferred to the manufacturing apparatus.

Therefore, when the supply device is an automatic device, it is possible to automate the process from moving the first component storage that needs to be supplied to supplying the first component storage to the manufacturing device.

In addition, for example, the production system may further include a parts warehouse for storing a plurality of the first parts storages supplied to the manufacturing apparatus, and the supply rack may temporarily store parts from the parts warehouse to all A plurality of the first component storages supplied by the manufacturing apparatus.

Therefore, the supply rack can function as a buffer zone for temporarily storing the first component storage, and for example, even if the component warehouse is located far from the manufacturing equipment, the first component storage can be efficiently supplied to the manufacturing equipment.

In addition, a supply method according to an aspect of the present disclosure is a supply method for a supply rack for supplying a first component storage container storing a plurality of components for specifying a substrate to a manufacturing apparatus.

Here, the component storage is a box for storing components. The parts storage is, for example, a case in which a carrier tape is stored. The component storage has a hollow portion, and accommodates, for example, a spirally wound carrier tape (a roll-shaped carrier tape not wound around a reel) or a carrier tape wound around a reel. In addition, the parts storage unit may further have a tape delivery device (not shown) for sending the carrier tape at intervals. The belt conveyor is composed of a sprocket provided in the vicinity of the lower part of the component suction position, a motor that rotates the sprocket, and the like. In this way, the parts storage device may be a parts storage device having a function of a feeder. The parts storage device may also be a box having a feeder function and a storage function.

In addition, the position, installation orientation, occupied area, and quantity of the component mounting device 20, the supply device 40, and the supply rack 100 arranged in the production floor F are examples, and are not limited to the example shown in FIG. to design appropriately. Moreover, in the production floor F, the conveyance route R for running the supply apparatus 40 is formed. The supply device 40 travels on this conveyance route R, and conveys the component storage device etc. which accommodated the electronic component from the supply rack 100 to the production area A. As shown in FIG. The conveyance route R is defined by physical information such as signs and guidance lines installed in the factory F, or route information and map information stored in the storage unit 45 (see FIG. 2 ) in the supply device 40 . In FIG. 1 , for convenience of explanation, the conveyance path R is simply shown as a straight line or a rectangle, but it is not limited thereto. The conveyance path R can be set in various shapes (for example, zigzag, inclined direction, etc.) as required.

In addition, the warehouse 60 is installed outside the production floor F, but may be installed inside the production floor F. As shown in FIG.

In addition, in the example of FIG. 1, in the production area A, three mounting substrate manufacturing lines L are respectively installed in a straight line. Each of the mounting substrate manufacturing lines L is constituted by including various manufacturing devices including the component mounting device 20 by which solder printing to the substrate, mounting (assembling) electronic components to the substrate, reflow soldering, etc. are automatically performed.

In addition, below, the new components storage which accommodated components is shown as the components storage 210, and the empty components storage is shown as the components storage 220. FIG. A new parts storage device refers to a new item of parts storage device (unused parts storage device), but may be a parts storage device in which the number of stored parts is a predetermined number or more. In addition, an empty parts storage device refers to a parts storage device in which zero components are stored, but may be a components storage device in which the number of stored components is less than a predetermined number.

As shown in FIG. 2 , the component mounting device 20 is configured to be able to communicate with the supply device 40 , the management device 50 , and the supply rack 100 . In addition, as shown in FIG. 3 , in the component mounting apparatus 20 , a pair of substrate transfer mechanisms 22 are arranged along the X-axis direction (substrate transfer direction) at the center of the main body base portion 21 . The substrate transport mechanism 22 has a pair of conveyor belt parts 22A extending along the X-axis direction, and a substrate holding mechanism provided by connecting the pair of conveyor belt parts 22A in the Y-axis direction (direction perpendicular to the X-axis direction in plan view). Section 22B. At each of the end portions of the substrate holding portion 22B, a substrate holder 22C for fixedly holding the substrate is disposed. The board conveyance mechanism 22 conveys the board|substrate supplied from the upstream side apparatus (for example, the printing soldering inspection apparatus 13 etc.), determines a position, and holds it.

In addition, a pair of front and rear component supply units 23 are provided on both sides (Y-axis positive side and Y-axis negative side) of the substrate conveyance mechanism 22 . A pair of wall portions 21A are respectively provided on both sides of the main body base portion 21 , and each of the component supply portions 23 is arranged in a space surrounded by the pair of wall portions 21A. Each of the component supply parts 23 has a feeder base 23A provided with a groove 23B in which a plurality of tape feeders 23C are fitted side by side as a feeder.

In addition, the component mounting apparatus 20 has a feeder cart 24 . The feeder cart 24 includes a loading unit 24A on the lower side of which a plurality of casters are arranged, and a plurality of reel stockers 24B arranged in different layers on the upper side of the loading unit 24A. Each of the reel stockers 24B houses the component storages, and the carrier tapes containing the electronic components are pulled out from each of the component storages, and the electronic components are supplied to the tape feeder 23C. Accordingly, the tape feeder 23C sends the carrier tape at intervals in the tape sending direction, and supplies the electronic components via the mounting head 27 of the component mounting device 20 .

In addition, a pair of Y-axis table mechanisms 25 are arranged along the Y-axis direction at both ends in the X-axis direction on the upper surface of the main body base portion 21 . Furthermore, between the pair of Y-axis table mechanisms 25, the X-axis table mechanism 26 is bridged between these Y-axis table mechanisms 25, and is assembled so that it can slide and move along the Y-axis direction. Furthermore, a mounting head 27 is attached to the front end portion of the X-axis table mechanism 26 so as to be slidably movable in the X-axis direction. In addition, both the X-axis table mechanism 26 and the Y-axis table mechanism 25 are constituted by a linear guide drive mechanism.

The mounting head 27 is a multi-head having a plurality of holding heads, and a component holding nozzle (not shown) is attached to the lower end of each holding head. The component holding nozzle holds the electronic components by vacuum suction using air pressure, and raises and lowers each one. Furthermore, the mounting head 27 has a Z-axis lifting mechanism (not shown) for lifting and lowering the component holding nozzle, and a θ-axis rotating mechanism (not shown) for rotating the component holding nozzle around the nozzle axis (for example, the Z axis). By driving the Y-axis table mechanism 25 and the X-axis table mechanism 26, the mounting head 27 can be positioned at an arbitrary position on the horizontal plane (XY plane). Accordingly, the mounting head 27 takes out the electronic component from the take-out position of the tape feeder 23C of the component supply unit 23 through the component holding nozzle.

Moreover, between the component supply part 23 and the board|substrate conveyance mechanism 22, the component recognition camera 28 is respectively laid. When the mounting head 27 that has taken out the electronic component from the component supply unit 23 moves above the component recognition camera 28 , the component recognition camera 28 takes an image of the electronic component held by the mounting head 27 . By performing recognition processing on the imaging result, recognition of electronic components, position detection, and the like are executed. In addition, a substrate recognition camera 29 is fixedly installed on the mounting head 27 . The substrate recognition camera 29 is arranged on the lower surface side of the X-axis table mechanism 26 and moves integrally with the mounting head 27 . As the mounting head 27 moves, the board recognition camera 29 moves above the board whose position is determined by the board transfer mechanism 22, and takes an image of the board.
