Abstract
Description
Technical Field
[0001] The technology disclosed in this specification relates to a component storage for storing components mounted on a substrate.
Background Art
[0002] A substrate production system for mounting components on a substrate to produce a component-mounted substrate is known. In this type of substrate production system, for example, a substrate flows through a component mounting line, and a plurality of components are mounted on this substrate. When a component-mounted substrate is produced and components are used on the component mounting line, it is necessary to replenish the components on the component mounting line. For this reason, in a conventional substrate production system, a component storage is provided near the component mounting line, and components to be replenished to the component mounting line may be stored in the component storage. The components stored in the component storage are shipped from the component storage according to the component usage status on the component mounting line and replenished to the component mounting line. As an example of a conventional component storage, for example, the component storage disclosed in JP-A-2019-218156 is known.
Summary of the Invention
Problems to be Solved by the Invention
[0003] By the way, among the components mounted on the substrate, there are components sensitive to humidity (hereinafter referred to as MSL components (Moisture Sensitivity Level Parts)). For MSL components, the exposure time (so-called floor life (indoor storage life)) that can be exposed on the production floor where the component mounting line is installed is set, and it is necessary to use them within the set floor life. In the conventional technology, MSL components are stored in a constant humidity storage that maintains a constant humidity, while components other than MSL components are stored in a normal component storage. Therefore, this specification provides a component storage that can store both MSL components and components other than MSL components.
Means for Solving the Problems
[0004] The component storage cabinet disclosed herein stores components that are mounted on a substrate by a component mounting machine. This component storage cabinet comprises a casing, a component storage section, and a moisture-proof layer. The casing comprises a bottom wall, a top 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 top wall. The component storage section is located inside the casing and houses the components. The moisture-proof layer is provided between the side wall and the component storage section and is arranged to surround the outer periphery of the component storage section. With this component storage cabinet, by providing a moisture-proof layer between the side wall and the component storage section, both MSL components and non-MSL components can be stored in the component storage section. [Brief explanation of the drawing]
[0005] [Figure 1] This is a perspective view of the parts storage cabinet in the embodiment, showing the front door in the open position. [Figure 2] This is a longitudinal cross-sectional view of the parts storage cabinet of the embodiment. [Figure 3] This is a cross-sectional view taken along line III-III in Figure 2. [Figure 4] This is a magnified partial cross-section of the loading / unloading section of the parts storage cabinet in the embodiment. [Figure 5] This is a block diagram showing the configuration of the control system for the parts storage cabinet in the embodiment. [Modes for carrying out the invention]
[0006] In the parts storage facility disclosed herein, the casing may further comprise a plurality of columnar sections, one end of which is fixed to the bottom wall and the other end to the ceiling wall. The plurality of columnar sections may be spaced apart in the circumferential direction and positioned radially inward from the outer periphery of the bottom wall and the outer periphery of the ceiling wall. A plurality of second openings may be formed by two circumferentially adjacent columnar sections, the bottom wall, and the ceiling wall. The parts storage section may be positioned radially inward from the plurality of second openings. A moisture barrier may be provided for each second opening and may include a moisture barrier sheet that closes the second opening. With such a configuration, the intrusion of moisture into the parts storage section can be suppressed by a simple configuration that only requires closing the second openings formed by the columnar sections, the bottom wall, and the ceiling wall with a moisture barrier sheet.
[0007] In the parts storage facility disclosed herein, the side wall may have an access port for moving parts in and out between the outside of the side wall and the parts storage area. The access port may include an access passage connecting the outside of the side wall and the parts storage area, a first shutter provided on the outside side of the access passage on the side wall for opening and closing the access passage, a second shutter provided on the parts storage area side of the access passage for opening and closing the access passage, and a control device for controlling the opening and closing of the first shutter and the second shutter. When one of the first shutter and the second shutter is in the open state, the control device controls the other of the first shutter and the second shutter. Closed state This configuration is also possible. With this configuration, parts can be loaded into and unloaded from the parts storage facility while either the first shutter or the second shutter is closed. This prevents moisture from entering the space inside the moisture barrier from the space outside the parts storage facility.
[0008] In the parts storage facility disclosed herein, the side walls may include panel panels on which entry and exit sections are provided. The casing may further include a frame that abuts against the outer peripheral edge of the back surface of the panel panel, and a sealing material disposed at the contact point between the frame and the outer peripheral edge of the panel panel. With such a configuration, it is possible to suppress the intrusion of moisture into the internal space of the parts storage facility from the periphery of the panel panel on which the entry and exit sections are provided.
[0009] In the parts storage facility disclosed herein, the parts storage unit may include a plurality of storage shelves for storing parts reels that each contain multiple parts. The parts storage facility may further include a reading unit for reading ID information assigned to the parts reels, a timing device for obtaining the time when the parts reels are stored in or out of the storage unit, and a storage device for associating and storing the ID information read by the reading unit with the storage time of the parts reels obtained by the timing device. With such a configuration, the storage time of parts reels containing MSL parts can be stored, and the floor life of the MSL parts can be managed.
[0010] The parts storage facility disclosed herein may further include a robotic mechanism that stores parts reels received from the receiving / discharging section into storage shelves, and also stores parts reels stored in the storage shelves from the receiving / discharging section. With such a configuration, the storage and retrieval of parts reels can be performed automatically.
[0011] (Examples) The following describes the component storage unit 100 according to the embodiment with reference to the drawings. The component storage unit 100 stores component reels 46 (shown in Figure 4) which are detachably attached to a component mounting machine (not shown). The component reels 46 stored in the component storage unit 100 are reels on which tape containing multiple components is wound, and are transported from the component storage unit 100 to the component mounting machine by an automatic transport device (not shown). The transported component reels 46 are attached to the component mounting machine (specifically, the component feeder of the component mounting machine), and the components supplied from the component reels 46 are mounted on the circuit board. The component reels 46 used in the component mounting machine are transported from the component mounting machine to the component storage unit 100 by the automatic transport device and stored in the component storage unit 100. Note that there are two types of component reels 46: one that contains MSL components with a set floor life, and another that contains components other than MSL components that do not have a set floor life. The parts storage unit 100 in this embodiment is capable of storing both parts reels containing MSL parts and parts reels containing parts other than MSL parts. The parts reel 46 is assigned ID information to identify the parts reel 46 and information about the parts contained in the parts reel 46 (for example, whether or not they are MSL parts). The various information assigned to the parts reel 46 can be read by an ID code (for example, a barcode, a 2D code, etc.) attached to the surface of the parts reel 46.
[0012] As shown in Figures 1-3, the parts storage unit 100 comprises a casing 10 and a parts storage section S provided inside the casing 10. The casing 10 comprises a bottom plate 20 (an example of a "bottom wall"), a top plate 18 (an example of a "top wall"), a side wall plate 14 that closes the opening formed between the bottom plate 20 and the top plate 18, a rear plate 16, and a door 12. The bottom plate 20 is a roughly rectangular plate when viewed from above and is installed on the same floor as the floor where the parts mounting machine is located. The top plate 18 is a roughly rectangular plate with the same shape as the bottom plate 20 when viewed from above and is positioned above the bottom plate 20 and parallel to it. That is, if the bottom plate 20 is moved upward parallel to it, the bottom plate 20 and the top plate 18 will coincide. The four openings formed between the outer periphery of the base plate 20 and the outer periphery of the ceiling plate 18 are closed at the front by a door 12 (an example of a "side wall" and an example of a "panel plate"), closed on the sides by a side wall plate 14 (an example of a "side wall"), and closed at the rear by a rear plate 16 (an example of a "side wall").
[0013] The side wall plate 14 has its lower end in contact with the bottom plate 20 and its upper end in contact with the ceiling plate 18. In this embodiment, the contact area between the side wall plate 14 and the bottom plate 20 is not sealed, nor is the contact area between the side wall plate 14 and the ceiling plate 18 sealed. In other words, moisture can move from the outside of the casing 10 to the inside of the casing 10 through the gaps between the side wall plate 14 and the bottom plate 20 and the gaps between the side wall plate 14 and the ceiling plate 18.
[0014] The rear panel 16 has its lower end in contact with the bottom panel 20 and its upper end in contact with the ceiling panel 18. In addition, both sides of the rear panel 16 are in contact with the left and right side wall panels 14. Similar to the side wall panels 14 described above, the contact area between the rear panel 16 and the bottom panel 20 is not sealed, nor is the contact area between the rear panel 16 and the ceiling panel 18, nor is the contact area between the rear panel 16 and the left and right side wall panels 14. In other words, moisture can move from the outside of the casing 10 to the inside of the casing 10 through the gaps between the rear panel 16 and the bottom panel 20, the gaps between the rear panel 16 and the ceiling panel 18, and the gaps between the rear panel 16 and the side wall panels 14.
[0015] The door 12 is a rectangular plate, and as shown in Figure 1, one of its sides is connected to the side of the side wall plate 14 by a hinge. Therefore, the door 12 is rotatable relative to the side wall plate 14 (i.e., the side wall plate 14 located on the rear side in Figure 1), and can be positioned to either close or open the front opening of the casing 10. When the door 12 closes the front opening of the casing 10, the outer peripheral edge of the back of the door 12 abuts against the frame formed by the bottom plate 20, the top plate 18, and the two side wall plates 14. A sealing member 44 (shown in Figure 3) is placed at the contact point between the door 12 and the frame. Specifically, the sealing member 44 is provided around the entire circumference of the frame. As a result, when the door 12 closes the front opening of the casing 10, the contact points (gaps) between the bottom plate 20, the top plate 18, and the side wall plates 14 and the door 12 are sealed by the sealing member 44, thereby restricting the movement of moisture from the outside of the casing 10 to the inside of the casing 10. The door 12 has an opening that serves as the entry and exit point for the parts reel 46. An entry and exit section 32 is provided adjacent to the opening formed in the door 12.
[0016] As shown in Figure 4, the loading / unloading section 32 includes a passage body 34 connected to an opening formed in the door 12. The passage body 34 is a cylindrical body with a rectangular cross-section and includes a loading / unloading passage 34a inside that connects the outside of the door 12 to the parts storage section S. The loading / unloading passage 34a is inclined (for example, at approximately 10° with respect to the horizontal) such that the end on the door 12 side is lower than the end on the parts storage section S side. A first shutter 36 is positioned at the door 12 side end of the loading / unloading passage 34a, and a second shutter 38 is positioned at the parts storage section S side end of the loading / unloading passage 34a. The opening and closing of the first shutter 36 and the second shutter 38 are performed by an opening / closing device 56 (shown in Figure 5). As will be described in detail later, the first shutter 36 and the second shutter 38 are never open at the same time; when the first shutter 36 is open, the second shutter 38 is closed, and when the second shutter 38 is open, the first shutter 36 is closed. Closed stateThe system is controlled in such a way that the outside of the door 12 and the parts storage section S do not come into direct contact, thereby preventing moisture from moving from the outside of the door 12 into the parts storage section S. The loading / unloading section 32 is also equipped with a reader 58 that reads the ID code attached to the surface of the parts reel 46 placed on the loading / unloading passage 34a.
[0017] As shown in Figure 3, the casing 10 is further provided with six support columns 40a to 40f (an example of "columnar parts"). The lower ends of the six support columns 40a to 40f are fixed to the upper surface of the bottom plate 20, while the upper ends are fixed to the lower surface of the ceiling plate 18. The ceiling plate 18 is supported above the bottom plate 20 by the six support columns 40a to 40f. The six support columns 40a to 40f are positioned inside the outer periphery of the bottom plate 20 and the outer periphery of the ceiling plate 18 (i.e., inside the outer periphery of the side wall plate 14 and the rear plate 16), spaced apart in the circumferential direction. Specifically, support columns 40a and 40f are positioned on both sides of the entrance / exit section 32, which is located adjacent to the door 12; support columns 40b and 40e are positioned near the center of the two side wall panels 14; and support columns 40c and 40d are positioned near the two side ends of the rear panel 16.
[0018] In this embodiment, the lower ends of six support columns 40a to 40f are fixed to the bottom plate 20, and their upper ends are fixed to the ceiling plate 18. As a result, an opening (an example of a "second opening") is formed by two circumferentially adjacent support columns (for example, 40a and 40b), the bottom wall 20, and the ceiling wall 18. Each of the openings formed between two circumferentially adjacent support columns is closed by moisture-proof sheets 42a to 42e. Specifically, the opening formed between support columns 40a and 40b is closed by moisture-proof sheet 42a, the opening formed between support columns 40b and 40c is closed by moisture-proof sheet 42b, the opening formed between support columns 40c and 40d is closed by moisture-proof sheet 42c, the opening formed between support columns 40d and 40e is closed by moisture-proof sheet 42d, and the opening formed between support columns 40e and 40f is closed by moisture-proof sheet 42e. This prevents moisture from entering the space enclosed 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 the component housing section S is provided within the space enclosed by this moisture-proof layer.
[0019] As shown in Figure 2, the parts storage section S has multiple reel magazines 22. Each of the multiple reel magazines 22 is provided with multiple reel storage shelves 24. Parts reels 46 can be stored in each of the multiple reel storage shelves 24. The end of the reel storage shelf 24 located on the central side within the casing 10 is open, and the parts reels 46 are inserted through this opening. The bottom surface of the reel storage shelf 24 is sloped so that the opening side is higher. This allows the parts reels 46 to be stably held in the reel storage shelf 24. In this embodiment, the inclination angle of the bottom surface of the reel storage shelf 24 is designed to be the same as the inclination angle of the loading / unloading passage 34a. Also, the inclination angle of the table 26, which will be described later, is designed to be the same as the inclination angle of the loading / unloading passage 34a. Note that in Figure 2, only the reel storage shelf 24 is shown for the reel magazine 22 shown in the upper right corner, but multiple reel storage shelves 24 are also formed for the other reel magazines 22.
[0020] As shown in FIG. 2, a plurality of reel magazines 22 are stacked and arranged in the vertical direction. Also, as shown in FIG. 3, a plurality of reel magazines 22 stacked in the vertical direction are arranged at intervals in the circumferential direction. That is, a table 26 is arranged at the center of the component 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. In FIG. 3, an example is illustrated in which a reel magazine 22a for accommodating a small component reel 46 and a reel magazine 22b for accommodating a large component reel 46 are arranged.
[0021] Here, the table 26 is used to store the component reel 46 stocked from the loading / unloading section 32 in the reel storage shelf 24 of the reel magazine 22, and to unload the component reel 46 stored in the reel storage shelf 24 from the loading / unloading section 32. Specifically, the table 26 is guided by a guide shaft 25 arranged in the storage space S and is movable in the vertical direction within the storage space S. That is, the lower end of the guide shaft 25 is connected to a 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 the motor 28 rotates the guide shaft 25. A ball screw is formed on the guide shaft 25, and a nut is screwed onto the ball screw of the guide shaft 25. This nut is connected to the table 26. Therefore, when the motor 28 rotates the guide shaft 25, the nut and the table 26 move in the vertical direction accordingly. Also, the table 26 is configured to be rotatable about its central axis and can be positioned at an arbitrary angle in the circumferential direction by an actuator 60 (illustrated in FIG. 5). By controlling the vertical position and the 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 also be positioned in an arbitrary reel storage shelf 24 of an arbitrary reel magazine 22.
[0022] Furthermore, the table 26 is equipped with a clamping device 30 for clamping and moving the parts reels 46. The clamping device 30 can move the parts reels 46 onto the table 46 by clamping the parts reels 46 that have been brought into the loading / unloading passage 34a of the loading / unloading section 32 and pulling them toward the table 26. The clamping device 30 can also move the parts reels 46 into the loading / unloading passage 34a by clamping and pushing the parts reels 46 that are on the table 26. Similarly, the clamping device 30 can move the parts reels 46 on the table 26 to the reel storage rack 24, or move the parts reels 46 stored in the reel storage rack 24 onto the table 26. Therefore, a robotic mechanism is configured, comprising a table 24, a mechanism for moving the table 24 vertically and rotating it around a central axis (such as a guide shaft 25, a motor 28, and an actuator 60 for rotating the table 26), and a clamping device 30, to house the parts reels 46 received from the loading / unloading section 32 into the reel storage shelf 24, and to unload the parts reels 46 stored in the reel storage shelf 24 back into the loading / unloading section 32.
[0023] Next, the configuration of the control system of the above-described component storage 100 will be described. As shown in FIG. 5, the component storage 100 is controlled by a control device 50. The control device 50 is composed of a computer including a CPU, a ROM, and a 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 orientation by driving the motor 28 and the actuator 60, moves the component reel 46 to a desired position by driving the clamp device 30, controls the opening and closing of the first shutter 36 and the second shutter 38 by driving the opening / closing device 56, and can read the ID code of the component reel 46 by the reading device 58. By the control device 50 controlling each part of the component storage 100, the component reel 46 is stored in the component storage 100 and the component reel 46 is taken out from the component storage 100. Note that the control device 50 is provided with a timer 52 (an example of a "time measuring device") for measuring the floor life of the MSL component (exactly, the component reel 46 accommodating the MSL component) and a storage unit 54 (an example of a "storage device") for storing the floor life of the MSL component.
[0024] Next, the operation when retrieving a parts reel 46 from the parts storage unit 100 will be described. First, the control device 50 drives the motor 28 and actuator 60 to position the table 26 to the desired position and orientation. That is, the motor 28 is driven to adjust the height of the table 26, and the actuator 60 is driven to adjust the orientation of the table 26, so that the front end of the table 26 (i.e., the end without the clamping device 30) faces the reel storage shelf 24 in which the parts reel 46 to be retrieved is stored. Once the table 20 is positioned, the control device 50 drives the clamping device 30 to move the parts reel 46 in the reel storage shelf 24 onto the table 26. Next, the control device 50 drives the motor 28 and actuator 60 to bring the front end of the table 26 facing 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. The control device 50 then drives the clamping device 30 to move the parts reel 46 on the table 26 to the inbound / outbound passage 34a of the inbound / outbound section 32. When the parts reel 46 moves to the inbound / outbound 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 ID code attached to the surface of the parts reel 46. The ID code read by the reading device 58 is input to the control device 50. The control device 50 determines from the input ID code whether or not the parts reel 46 to be issued contains MSL parts. If the parts reel 46 to be issued contains MSL parts, the control device 50 stores the time counted by the timer 52 as the issuance time of the parts reel 46 in the storage unit 54. 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 automated transport device that transports the parts reel 46 takes the parts reel 46 from the loading / unloading passage 34a and transports it to the designated parts mounting machine.
[0025] On the other hand, when a parts reel 46 is to be stored in the parts storage warehouse 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 parts reel 46 to be stored onto the storage / return passage 34a. Next, the control device 50 drives the opening / closing device 56 to close both the first shutter 36 and the second shutter 38, and in this state, the reading device 58 reads the ID code attached to the surface of the parts reel 46. The ID code read by the reading device 58 is input to the control device 50. The control device 50 determines from the input ID code whether or not the parts reel 46 to be stored contains MSL parts. If the parts reel 46 to be stored contains MSL parts, the control device 50 stores the time counted by the timer 52 as the storage time of the parts reel 46 in the storage unit 54. Therefore, for the parts reel 46 that contains the MSL parts, both the time it was taken out of the parts storage 100 and the time it was put into the parts storage 100 are stored in the memory unit 54. Next, the control device 50 drives the motor 28 and actuator 60 to face the tip of the table 26 toward the loading / unloading section 32, and at the same time 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 clamping device 30 to move the parts reel 46 on the loading / unloading passage 34a onto the table 26. Next, the control device 50 drives the motor 28 and actuator 60 to face the tip of the table 26 toward the reel storage shelf 24 in which the parts reel 46 is stored. Then, the control device 50 drives the clamping device 30 to move the parts reel 46 on the table 26 into the reel storage shelf 24. This completes the placement of the parts reel 46 into the reel storage rack 24.
[0026] As described above, in the parts storage unit 100 of this embodiment, the contact points between the bottom plate 20, side wall plates 14, rear plate 16, and ceiling plate 18 of the casing 10 are not sealed, and moisture intrusion into the parts storage unit S from the outside is prevented by moisture-proof sheets 42a to 42e provided inside the casing 10. In other words, the mechanical strength required for the casing 10 is ensured by the bottom plate 20, side wall plates 14, rear plate 16, and ceiling plate 18, while moisture intrusion into the parts storage unit S is ensured by moisture-proof sheets 42a to 42e provided inside the casing 10. For this reason, moisture-proof functionality can be achieved with a simpler structure compared to a structure in which a sealing structure is provided at the contact points between the bottom plate 20, side wall plates 14, rear plate 16, and ceiling plate 18. In particular, since the moisture-proof sheets 42a to 42e only need to ensure moisture resistance, a flexible sheet material that is easily deformable can be used. As a result, by attaching the moisture-proof sheets 42a to 42e to the casing 10, the parts storage section S can be surrounded by the moisture-proof sheets 42a to 42e. Therefore, the manufacturing process of the parts storage unit 100 can be simplified, and the parts storage unit 100 can be manufactured at a low cost.
[0027] Furthermore, in the parts storage cabinet 100 of this embodiment, a first shutter 36 and a second shutter 38 are provided at the loading / unloading section 32 for loading and unloading parts reels 46. When loading or unloading parts reels 46 into or out of the parts storage cabinet 100, at least one of the first shutter 36 and the second shutter 38 is always closed. As a result, the outside of the parts storage cabinet 100 and the inside of the parts storage section S do not come into direct contact, preventing moisture from entering the parts storage section S. This ensures that the moisture-proof function of the parts storage cabinet 100 is well maintained.
[0028] Furthermore, in the parts storage unit 100 of this embodiment, the time of entry into and exit from the parts storage unit 100 is stored in the storage unit 54 for the parts reels 46 that contain MSL parts. This makes it possible to calculate the time that the MSL parts were outside the parts storage unit 100, and to appropriately manage the floor life of the MSL parts. In addition, since the entire parts storage unit S has a moisture-proof function, parts reels 46 that contain MSL parts and parts reels 46 that contain parts other than MSL parts can be stored in the same parts storage unit 100.
[0029] Although the parts storage unit 100 according to this embodiment has been described in detail above, the technology disclosed herein is not limited to the configuration of the above embodiment. For example, in the above embodiment, the parts storage unit 100 was an example of storing tape-type parts reels, but the parts storage unit may store parts in a manner other than tape-type parts reels (e.g., trays, etc.), or a parts feeder with parts reels set in it may be stored in the parts storage unit. Furthermore, the reel magazine 22 that houses the parts reels 46 and the robot mechanism that handles the parts reels 46 can be of a different nature than that of the above embodiment.
[0030] 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 technologies described in the claims include various modifications and changes to the specific examples illustrated above. For example, this specification also discloses a technical concept in which "the parts storage facility described in claim 3" is changed to "the parts storage facility described in claim 3 or 4" in claim 5. The technical elements described in this specification or in the drawings exhibit technical usefulness individually or in various combinations, and are not limited to the combinations described in the claims at the time of filing. Furthermore, the technologies illustrated in this specification or in the drawings can achieve multiple objectives simultaneously, and achieving even one of these objectives itself constitutes technical usefulness.
