Description

parts storage

The technology disclosed herein relates to a component storage that stores components to be mounted on a board.

A board production system is known that produces a component-mounted board by mounting components on a board. In this type of board production system, for example, a board flows through a component mounting line, and a plurality of components are mounted on this board. When a component mounting board is produced and the components are used on a component mounting line, it becomes necessary to replenish the component mounting line with components. For this reason, in conventional board production systems, a component storage is sometimes provided near the component mounting line, and the components to be replenished to the component mounting line are stored in the component storage. The parts stored in the parts storage are taken out from the parts storage depending on the usage status of the parts on the component mounting line, and are replenished on the component mounting line. As an example of a conventional parts storage, for example, a parts storage disclosed in Japanese Patent Application Laid-Open No. 2019-218156 is known.

By the way, among the components mounted on the board, there are components that are sensitive to humidity (hereinafter referred to as MSL components (Moisture Sensitivity Level Parts)). For MSL components, a time period during which they can be exposed to a production floor where a component mounting line is installed (so-called floor life (indoor storage life)) is set, and it is necessary to use them within the set floor roughness. In the conventional technology, MSL parts are stored in a constant humidity storage where humidity is kept constant, while parts other than MSL parts are stored in a normal parts storage. Therefore, this specification provides a parts storage that can store both MSL parts and parts other than MSL parts.

The component storage disclosed in this specification stores components mounted on a board by a component mounting machine. This parts storage includes a casing, a parts storage section, and a moisture barrier layer. The casing includes a bottom wall, a ceiling wall, and a side wall that closes a first opening formed between the outer periphery of the bottom wall and the outer periphery of the ceiling wall. The component housing section is arranged inside the casing and stores components. The moisture-proof layer is provided between the side wall and the component accommodating portion, and is arranged so as to surround the outer periphery of the component accommodating portion. According to this parts storage, by providing a moisture-proof layer between the side wall and the parts storage part, both MSL parts and parts other than MSL parts can be stored in the parts storage part.

A plurality of second openings may be formed by two circumferentially adjacent columnar parts, a bottom wall, and a ceiling wall. The component accommodating portion may be arranged radially inner than the plurality of second openings. The moisture-proof layer may be provided for each second opening and may include a moisture-proof sheet that closes the second opening. According to such a configuration, it is possible to suppress moisture from entering the component housing section by simply closing the second opening formed by the columnar section, the bottom wall, and the ceiling wall with a moisture-proof sheet. .

In the parts storage disclosed in this specification, the side wall may include an entry/exit section for entering and exiting parts between the outside of the side wall and the parts storage section. The loading and unloading section includes an loading and unloading passage that communicates the outside of the side wall with the parts storage section, a first shutter that is provided on the outside of the side wall of the loading and unloading passage and opens and closes the loading and unloading passage, and a parts storage section of the loading and unloading passage. The storage unit may include a second shutter that is provided on the storage section side and opens and closes the entry/exit passage, and a control device that controls opening and closing of the first shutter and the second shutter. When the control device opens one of the first shutter and the second shutter, the control device may open the other of the first shutter and the second shutter. According to such a configuration, it is possible to carry parts into and out of the parts storage with either the first shutter or the second shutter closed. Therefore, it is possible to suppress moisture from entering the space inside the moisture-proof layer from the space outside the parts storage.

In the parts storage disclosed in this specification, the side wall may include a panel board on which an entry/exit section is provided. The casing may further include a frame body with which the outer peripheral edge of the back surface of the panel plate comes into contact, and a sealing material disposed at a contact area between the frame body and the outer peripheral edge of the panel plate. According to such a configuration, it is possible to suppress moisture from entering the internal space of the parts storage from the periphery of the panel board in which the storage/unloading section is provided.

(Example)
Hereinafter, a parts storage 100 according to an embodiment will be described with reference to the drawings. The component storage 100 stores a component reel 46 (shown in FIG. 4) that is removably attached to a component mounting machine (not shown). The component reel 46 stored in the component storage 100 is a reel wrapped with tape that accommodates a plurality of components, and is transported from the component storage 100 to the component mounting machine by an automatic transport device (not shown). The transported component reel 46 is attached to a component mounting machine (specifically, a component feeder of the component mounting machine), and the components supplied from the component reel 46 are mounted on a board. The component reel 46 used in the component mounter is transported from the component mounter to the component storage 100 by an automatic transport device, and is stored in the component storage 100. Note that the component reel 46 includes one that accommodates MSL components with a set floor life, and one that accommodates components other than MSL components for which a floor life is not set. The parts storage 100 of this embodiment is capable of storing both parts reels that contain MSL parts and parts reels that contain parts other than MSL parts. Note that the parts reel 46 is given ID information for identifying the parts reel 46 and information regarding the parts accommodated in the parts reel 46 (for example, information such as whether it is an MSL part or not). Various information given to the parts reel 46 can be read by an ID code (for example, a bar code, a two-dimensional code, etc.) pasted on the surface of the parts reel 46.

As shown in FIGS. 1 to 3, the parts storage 100 includes a casing 10 and a parts storage section S provided within the casing 10. The casing 10 includes a bottom plate 20 (an example of a "bottom wall"), a ceiling board 18 (an example of a "ceiling wall"), a side wall board 14 that closes an opening formed between the bottom board 20 and the ceiling board 18, A rear plate 16 and a door 12 are provided. The bottom plate 20 is a substantially rectangular plate material when viewed from above, and is installed on the same floor where the component mounting machine is placed. The ceiling plate 18 is a substantially rectangular plate material having the same shape as the bottom plate 20 when viewed from above, and is disposed above the bottom plate 20 in parallel with the bottom plate 20. That is, when the bottom plate 20 is moved upward in parallel, the bottom plate 20 and the ceiling plate 18 are brought into alignment. The four openings formed between the outer periphery of the bottom plate 20 and the outer periphery of the ceiling plate 18 are closed at the front by the door 12 (an example of a "side wall" and an example of a "panel board"), The side surface is closed by a side wall plate 14 (an example of a "side wall"), and the rear surface is closed by a rear plate 16 (an example of a "side wall").

The lower end of the side wall plate 14 is in contact with the bottom plate 20, and the upper end thereof is in contact with the ceiling plate 18. In this embodiment, the contact portion between the side wall plate 14 and the bottom plate 20 is not sealed, and the contact portion between the side wall plate 14 and the ceiling plate 18 is also not sealed. That is, moisture can move from the outside of the casing 10 to the inside of the casing 10 through the gap between the side wall plate 14 and the bottom plate 20 and the gap between the side wall plate 14 and the ceiling plate 18.

The rear plate 16 has its lower end in contact with the bottom plate 20 and its upper end in contact with the ceiling plate 18. Further, both side portions of the rear plate 16 are in contact with the left and right side wall plates 14. Similar to the side wall plate 14 described above, the abutment area between the rear plate 16 and the bottom plate 20 is not sealed, and the abutment area between the rear plate 16 and the ceiling plate 18 is also not sealed. 16 and the left and right side wall plates 14 are also not sealed. That is, through the gap between the rear plate 16 and the bottom plate 20, the gap between the rear plate 16 and the ceiling plate 18, and the gap between the rear plate 16 and both side wall plates 14, from the outside of the casing 10 to the inside of the casing 10. Moisture movement is possible.

The door 12 is a rectangular plate material, and as shown in FIG. 1, one side portion is connected to the side portion of the side wall plate 14 by a hinge. Therefore, the door 12 is rotatable relative to the side wall plate 14 (that is, the side wall plate 14 located on the back side in FIG. The front opening can be kept open. When the door 12 closes the front opening of the casing 10, the outer peripheral edge of the back surface of the door 12 comes into contact with a frame formed by the bottom plate 20, the ceiling plate 18, and the two side wall plates 14. A sealing member 44 (shown in FIG. 3) is arranged at the abutting portion between the door 12 and the frame. Specifically, the seal member 44 is provided around the entire circumference of the frame described above. As a result, when the door 12 closes the front opening of the casing 10, the contact portions (gap) between the bottom plate 20, the ceiling plate 18, and the side wall plate 14 and the door 12 are sealed by the sealing member 44, and the opening of the casing 10 is sealed. Movement of moisture from the outside to the inside of the casing 10 is restricted. Note that the door 12 is formed with an opening that serves as an entry/exit entrance for the component reel 46 . Adjacent to the opening formed in the door 12, an entry/exit section 32 is provided.

As shown in FIG. 4, the loading/unloading section 32 includes a passage main body 34 connected to an opening formed in the door 12. The passage main body 34 is a cylindrical body with a rectangular cross section, and includes therein an entry/exit passage 34a that communicates the outside of the door 12 with the parts storage section S. The entry/exit passage 34a is inclined (for example, about 10 degrees with respect to the horizontal direction) so that the end on the door 12 side is lower than the end on the component storage section S side. A first shutter 36 is arranged at the end of the entry/exit passage 34a on the door 12 side, and a second shutter 38 is arranged at the end of the entry/exit passage 34a on the parts storage section S side. The first shutter 36 and the second shutter 38 are opened and closed by an opening/closing device 56 (shown in FIG. 5). As will be described in detail later, the first shutter 36 and the second shutter 38 are never open at the same time, and when the first shutter 36 is open, the second shutter 38 is closed, and when the first shutter 36 is open, the second shutter 38 is closed. When the second shutter 38 is in the open state, the first shutter 36 is controlled to be in the open state. As a result, the outside of the door 12 and the component storage section S are not directly communicated with each other, and movement of moisture from the outside of the door 12 into the component storage section S is suppressed. The loading/unloading section 32 is provided with a reading device 58 that reads an ID code affixed to the surface of the component reel 46 arranged on the loading/unloading passage 34a.

As shown in FIG. 3, the casing 10 further includes six pillars 40a to 40f (an example of a "column portion"). The six pillars 40a to 40f have their lower ends fixed to the upper surface of the bottom plate 20, and their upper ends fixed to the lower surface of the ceiling plate 18. The ceiling plate 18 is supported above the bottom plate 20 by six pillars 40a to 40f. The six pillars 40a to 40f are spaced apart in the circumferential direction at positions inside the outer periphery of the bottom plate 20 and the ceiling plate 18 (that is, inside the outer peripheries of the side wall plates 14 and the rear plate 16). It is located. Specifically, struts 40a and 40f are arranged on both sides of the storage entry/exit section 32 provided adjacent to the door 12, and struts 40b and 40e are arranged near the center of the two side wall plates 14.

Supports

40c and 40d are arranged near the two side ends of the rear plate 16.

In this embodiment, the lower ends of the six pillars 40a to 40f are fixed to the bottom plate 20, and their upper ends are fixed to the ceiling plate 18. Therefore, an opening (an example of a "second opening") is formed by two circumferentially adjacent columns (for example, 40a, 40b), the bottom wall 20, and the ceiling wall 18. Each of the openings formed between two circumferentially adjacent columns is closed by moisture-proof sheets 42a to 42e. Specifically, the opening formed between the

pillars

40a and 40b is closed by the moisture-proof sheet 42a, the opening formed between the

pillars

40b and 40c is closed by the moisture-proof sheet 42b, and the opening formed between the

pillars

40c and 40d is closed by the moisture-proof sheet 42a. The opening formed between them is closed by a moisture-proof sheet 42c, the opening formed between

struts

40d and 40e is closed by a moisture-proof sheet 42d, and the opening formed between

struts

40e and 40f is closed by a moisture-proof sheet. 42e. This prevents moisture from entering the space surrounded by the moisture-proof sheets 42a to 42e. In this embodiment, a moisture-proof layer is formed by the moisture-proof sheets 42a to 42e, and a component storage section S is provided in a space surrounded by this moisture-proof layer.

As shown in FIG. 2, a plurality of reel magazines 22 are arranged in the component storage section S. Each of the plurality of reel magazines 22 is provided with a plurality of reel storage shelves 24. The component reel 46 can be stored in each of the plurality of reel storage shelves 24. The reel storage shelf 24 has an open end located on the center side within the casing 10, and a component reel 46 is inserted through this opening. The bottom surface of the reel storage shelf 24 is inclined so that the opening side is higher. Thereby, the component reel 46 can be stably held on the reel storage shelf 24. In this embodiment, the angle of inclination of the bottom surface of the reel storage shelf 24 is designed to be the same as the angle of inclination of the entry/exit passage 34a. Further, the inclination angle of the table 26, which will be described later, is also designed to be the same as the inclination angle of the loading/unloading passage 34a. Although the reel storage shelves 24 are shown only in the reel magazine 22 displayed at the upper right end in FIG. 2, a plurality of reel storage shelves 24 are formed in other reel magazines 22 as well.

As shown in FIG. 2, a plurality of reel magazines 22 are stacked in the vertical direction, and as shown in FIG. 3, a plurality of reel magazines 22 stacked in the vertical direction are spaced apart in the circumferential direction. There are multiple locations. That is, a table 26 is arranged at the center of the parts storage section S, and a plurality of reel magazines 22 stacked in the vertical direction are arranged at intervals in the circumferential direction so as to surround the table 26. FIG. 3 shows an example in which a reel magazine 22a that accommodates a small component reel 46 and a reel magazine 22b that accommodates a large component reel 46 are arranged.

Here, the table 26 stores the component reel 46 received from the storage/unloading section 32 in the reel storage shelf 24 of the reel magazine 22, and also stores the component reel 46 stored in the reel storage shelf 24 from the storage/unloading section 32. Used for issuing goods. Specifically, the table 26 is guided by a guide shaft 25 disposed within the accommodation space S, and is movable within the accommodation space S in the vertical direction. That is, the lower end of the guide shaft 25 is connected to the motor 28, and the upper end of the guide shaft 25 is rotatably supported by the ceiling plate 18. The motor 28 is fixed to the bottom plate 20 and rotates the guide shaft 25. A ball screw is formed on the guide shaft 25, and a nut is screwed into the ball screw of the guide shaft 25. This nut is connected to table 26. Therefore, when the motor 28 rotates the guide shaft 25, the nut and table 26 move in the vertical direction accordingly. Further, the table 26 is configured to be rotatable around its central axis, and can be positioned at any angle in the circumferential direction by an actuator 60 (shown in FIG. 5). By controlling the vertical position and angle around the central axis of the table 26, the tip of the table 26 can be positioned with respect to the loading/unloading section 32, and can be placed on any reel storage shelf 24 of any reel magazine 22. Positioning is possible.

Further, the table 26 is provided with a clamping device 30 that clamps and moves the component reel 46. The clamp device 30 can move the component reel 46 onto the table 46 by clamping the component reel 46 carried into the loading/unloading passage 34a of the loading/unloading section 32 and pulling it toward the table 26. Further, the clamping device 30 can move the component reel 46 to the storage passage 34a by clamping and pushing out the component reel 46 on the table 26. Similarly, the clamp device 30 can move the component reel 46 on the table 26 to the reel storage shelf 24, or move the component reel 46 stored in the reel storage shelf 24 onto the table 26. Therefore, the loading/unloading section 30 is operated by the table 24, a mechanism for vertically moving the table 24 and rotating it around the central axis (guide shaft 25, motor 28, actuator 60 for rotating the table 26, etc.), and a clamp device 30. A robot mechanism is configured to store the component reels 46 stored in the reel storage shelf 24 from the reel storage shelf 24 and to unload the component reels 46 stored in the reel storage shelf 24 to the storage/unloading section 32.

Next, the configuration of the control system of the above-mentioned parts storage 100 will be explained. As shown in FIG. 5, the parts storage 100 is controlled by a control device 50. The control device 50 is configured by a computer including a CPU, ROM, and RAM. A motor 28 , a clamp device 30 , an opening/closing device 56 , a reading device 58 , and an actuator 60 are connected to the control device 50 . The control device 50 positions the table 26 at a desired position and in a desired direction by driving the motor 28 and the actuator 60, and moves the component reel 46 to a desired position by driving the clamp device 30. Further, by driving the opening/closing device 56, opening/closing of the first shutter 36 and the second shutter 38 can be controlled, and the ID code of the component reel 46 can be read by the reading device 58. The control device 50 controls each part of the parts storage 100, so that the parts reel 46 is loaded into the parts storage 100 and the parts reel 46 is taken out from the parts storage 100. The control device 50 includes a timer 52 (an example of a "timekeeping device") for timing the floor life of MSL components (more precisely, the component reel 46 that accommodates the MSL components), and a timer 52 (an example of a "timekeeping device") for measuring the floor life of the MSL components. A storage unit 54 (an example of a "storage device") is provided for storing information.

Next, the operation when taking out the parts reel 46 from the parts storage 100 will be described. First, the control device 50 positions the table 26 at a desired position and in a desired direction by driving the motor 28 and the actuator 60. That is, the motor 28 is moved so that the tip of the table 26 (that is, the end where the clamp device 30 is not provided) faces the reel storage shelf 24 in which the component reel 46 to be delivered is stored. The height of the table 26 is adjusted by driving, and the direction of the table 26 is adjusted by driving the actuator 60. When the table 20 is positioned, the control device 50 drives the clamp device 30 to move the component reel 46 in the reel storage shelf 24 onto the table 26. Next, the control device 50 drives the motor 28 and the actuator 60 to cause the tip of the table 26 to face the loading/unloading section 32 . Next, the control device 50 drives the opening/closing device 56 to open the second shutter 38 while keeping the first shutter 36 closed. Then, the control device 50 drives the clamp device 30 to move the component reel 46 on the table 26 to the loading/unloading passage 34a of the loading/unloading section 32. When the parts reel 46 moves to the loading/unloading passage 34a, the control device 50 drives the opening/closing device 56 to close the first shutter 36 and the second shutter 38, and in this state, the reading device 58 reads the parts reel 46. Read the ID code pasted on the surface. The ID code read by the reader 58 is input to the control device 50. The control device 50 determines whether the parts reel 46 to be delivered is one that accommodates MSL parts based on the input ID code. When the parts reel 46 to be delivered contains MSL parts, the control device 50 causes the storage unit 54 to store the time counted by the timer 52 as the delivery time of the parts reel 46 . Next, the control device 50 drives the opening/closing device 56 to open the first shutter 36 while keeping the second shutter 38 closed. Then, the automatic transport device that transports the component reel 46 takes out the component reel 46 located on the loading/unloading passage 34a and transports it to a predetermined component mounting machine.

On the other hand, when storing the parts reel 46 into the parts storage 100, the control device 50 first drives the opening/closing device 56 to open the first shutter 36 while keeping the second shutter 38 closed. . When the first shutter 36 is opened, the automatic transport device moves the component reel 46 to be stored onto the storage/unloading passage 34a. Next, the control device 50 drives the opening/closing device 56 to close the first shutter 36 and the second shutter 38, and in this state, the ID code affixed to the surface of the component reel 46 is read by the reader 58. Read. The ID code read by the reader 58 is input to the control device 50. The control device 50 determines whether the parts reel 46 to be stocked accommodates MSL parts based on the input ID code. When the parts reel 46 to be stocked accommodates MSL parts, the control device 50 causes the storage unit 54 to store the time counted by the timer 52 as the stocking time of the parts reel 46 . Therefore, for the parts reel 46 that accommodates MSL parts, both the time when the part reel 46 leaves the parts storage 100 and the time when it enters the parts storage 100 are stored in the storage unit 54 . Next, the control device 50 drives the motor 28 and the actuator 60 to make the tip of the table 26 face the loading/unloading section 32, and at the same time drives the opening/closing device 56 to close the first shutter 36. The second shutter 38 remains open. Then, the control device 50 drives the clamp device 30 to move the component reel 46 on the loading/unloading passage 34a onto the table 26. Next, the control device 50 drives the motor 28 and the actuator 60 to cause the tip of the table 26 to face the reel storage shelf 24 in which the component reel 46 is stored. Then, the control device 50 drives the clamp device 30 to move the component reel 46 on the table 26 into the reel storage shelf 24. This completes the storage of the component reel 46 in the reel storage shelf 24.

As explained above, in the parts storage 100 of the present embodiment, the contact portions of the bottom plate 20, the side wall plate 14, the rear plate 16, and the ceiling plate 18 of the casing 10 are not sealed, and the inside of the casing 10 is The moisture-proof sheets 42a to 42e provided in the parts prevent moisture from entering into the component housing section S from the outside. That is, while the mechanical strength required for the casing 10 is ensured by the bottom plate 20, the side wall plates 14, the rear plate 16, and the ceiling plate 18, the moisture intrusion into the parts housing section S is prevented by the moisture-proof sheet provided inside the casing 10. 42a to 42e. Therefore, the moisture-proof function can be realized with a simpler structure than a structure in which a seal structure is provided at the contact portions of the bottom plate 20, the side wall plate 14, the rear plate 16, and the ceiling plate 18, respectively. In particular, since the moisture-proof sheets 42a to 42e only need to ensure moisture resistance, flexible sheet materials that are easily deformable can be used. As a result, by pasting the moisture-proof sheets 42a-42e on the casing 10, the component housing section S can be surrounded by the moisture-proof sheets 42a-42e. Therefore, the manufacturing process of the parts storage 100 can be simplified, and the parts storage 100 can be manufactured at low cost.

Furthermore, in the parts storage 100 of this embodiment, a first shutter 36 and a second shutter 38 are provided in the storage/unloading section 32 for loading/unloading the component reel 46. When loading and unloading the component reel 46 into and out of the component storage 100, at least one of the first shutter 36 and the second shutter 38 is always closed. Therefore, there is no direct communication between the outside of the parts storage 100 and the inside of the parts storage part S, and moisture is prevented from entering into the parts storage part S. Thereby, the moisture-proof function of the parts storage 100 is maintained well.

Further, in the parts storage 100 of the present embodiment, the storage unit 54 stores the time of entry into the parts storage 100 and the time of departure for the parts reel 46 that accommodates MSL parts. Thereby, it is possible to calculate the time that the MSL parts have been placed outside the parts storage 100, and it is possible to appropriately manage the floor life of the MSL parts. Furthermore, since the entire component storage section S has a moisture-proof function, the component reel 46 that accommodates MSL components and the component reel 46 that accommodates components other than MSL components can be stored in the same component storage 100. .

Although the parts storage 100 according to the present embodiment has been described above in detail, the technology disclosed in this specification is not limited to the configuration of the above embodiment. For example, in the above embodiment, the parts storage 100 is an example in which tape-type component reels are stored, but the parts storage is also used to store components in a form other than tape-type component reels (for example, in trays, etc.). Alternatively, the parts feeder with the parts reel set may be stored in a parts storage. Further, as for the reel magazine 22 that accommodates the component reel 46 and the robot mechanism that handles the component reel 46, it is possible to use modes other than those in the above embodiments.

Although specific examples of the present invention have been described in detail above, these are merely illustrative and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes to the specific examples illustrated above. For example, the present specification also discloses a technical idea in which "the parts storage according to claim 3" is changed to "the parts storage according to claim 3 or 4" in claim 5. The technical elements described in this specification or the drawings exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims as filed. Furthermore, the techniques illustrated in this specification or the drawings can achieve multiple objectives simultaneously, and achieving one of the objectives has technical utility in itself.
