Description

[Technical Field]

[0001] The present invention provides The present invention relates to a carrier tape management system and management method. [Background technology]

[0002] A carrier tape having storage recesses capable of storing components is wound around a take-up reel 10 after molding (see, for example, Patent Document 1). Then, a set of multiple rolls (for example, two or three rolls) is stored in a storage case 20 and shipped. At this time, a control number (identification means 22) is assigned to the storage case 20 to perform quality control and production control of the carrier tape (see FIG. 8). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-210019 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, when there is a product complaint or a malfunction occurs in the molding device, it is necessary to contain the carrier tape to be extracted, but because the control numbers assigned are not for each winding reel 10 but for each storage case 20, it is difficult to identify and select the carrier tape (winding reel) to be extracted. In other words, it is not possible to distinguish between the first and second windings of the multiple winding reels 10 in the storage case 20, and it is not possible to, for example, identify the molding time or molding sequence, or determine whether the tapes were molded on the same molding line.

[0005] Therefore, even if the defective carrier tape could be enclosed, the plurality of take-up reels 10 stored in a certain storage case 20 at the same time would also have to be discarded, resulting in poor yield.

[0006] The present invention has been made in view of the above-mentioned problems, and has as its object to provide a management system and a management method for carrier tapes that can be managed in units of take-up reels. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the present invention provides a carrier tape management system that manages a take-up reel on which a carrier tape is wound and a storage case that can store a plurality of the take-up reels, the system comprising: The carrier tape is formed by molding a plurality of component storage recesses and feed holes at predetermined intervals along the length of a strip-shaped resin sheet using a molding device. When the tape is wound onto a take-up reel, a portion of the tape is taken out as a sample for quality control. The take-up reel is assigned a unique identification number on the flange, and samples of the carrier tape are managed using the same identification number. The storage case is assigned a unique secondary identification number, The management system includes a storage unit that stores an inspection record created at the end of a manufacturing operation of the carrier tape, an identification number associated with the inspection record, and a second identification number, and a display unit that can display the contents stored in the storage unit; If a defect occurs during the manufacture of the carrier tape, a search is made to determine whether or not there is a winding reel with the same lot number based on the lot number in the defect data of the inspection record linked to the identification number stored in the memory unit of the management system, and if there is a winding reel with the same lot number, the carrier tape of the winding reel with the same lot number is identified and displayed on the display unit of the management system. The management system may be a production management system for a factory having a carrier tape forming device. The management system may also include a communication unit that outputs the contents stored in the memory unit to a control unit of the carrier tape forming device or a production management system for a factory that has a forming device. Furthermore, the management system can store the identification number in the storage unit in association with measurement data when the dimensions of the sample are measured and inspection data when the external appearance of the sample is inspected. In addition, in order to solve the above problem, the present invention is characterized in that after multiple take-up reels with carrier tape wound on them are stored in a storage case and shipped, traceability of the carrier tape is performed for each take-up reel using the carrier tape management system described in claim 1 or 2. [Effects of the Invention]

[0008] According to the present invention, It is possible to provide a management system and a management method for carrier tape that can be managed on a reel-by-reel basis. That is, an identification number is assigned to each reel, and this reel identification number is linked to a lot number. Therefore, if a defect occurs, the reel to be enclosed, in other words, the carrier tape from which the sample was taken, can be directly identified. However, depending on the circumstances under which the defect occurs, the reel to be enclosed is not limited to one, and may be stored across multiple storage cases. Even in such cases, it is possible to identify the reel in a specific storage case. [Brief explanation of the drawings]

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the embodiments of this specification, the same components are designated by the same reference numerals throughout.

[0011] First, the carrier tape 1 will be described. FIG. 1 is a perspective view showing a carrier tape 1. As shown in FIG.

[0012] The carrier tape 1 stores a plurality of components, and is used for storing, transporting, and smoothly supplying the components to a mounting machine that mounts the components on a substrate. For example, the components include electronic components and precision components.

[0013] This carrier tape 1 has a plurality of feed holes 2 and storage recesses 3 capable of storing components, each at a predetermined interval along the longitudinal direction (feed direction) of the tape. The area between the feed holes 2 and the storage recesses 3 is called a sprocket flange, and the area on the opposite side of the storage recesses 3 from the feed holes 2 is called a free flange.

[0014] The feed holes 2 are circular in plan view, but the shape, dimensions and spacing of the feed holes 2 are formed to suit the feed mechanism of the mounting machine, etc. Note that the feed holes 2 may also be formed on both the left and right sides of the storage recess 3 in the width direction, along the two longitudinal sides of the tape.

[0015] On the other hand, the storage recesses 3 are generally rectangular, but are formed to fit the shape of the components, so the shape, dimensions, and spacing are designed appropriately. The storage recesses 3 are formed at a predetermined pitch P1 along the longitudinal direction of the tape, and this pitch P1 depends on the opening dimensions of the storage recesses 3, but is, for example, about 15 mm to 50 mm.

[0016] In addition, in the carrier tape 1 of this embodiment, a bottom hole 5 for inspection is formed in the bottom surface of the storage recess 3. This bottom hole 5 has a diameter of about 0.2 mm to 2.5 mm. Note that the bottom surface of the storage recess 3 may be formed as a protruding seat, and the bottom hole 5 may be formed in the seating surface.

[0017] The carrier tape 1 is formed from a resin sheet made of, for example, synthetic resin such as polyvinyl chloride, polystyrene, amorphous polyethylene terephthalate, polycarbonate, or polypropylene, or any of these resins kneaded with carbon to impart conductivity, or a resin sheet with a conductive coating on its surface. The width W of the carrier tape 1 is not particularly limited and may be 4 mm, 8 mm, 12 mm, 16 mm, 24 mm, 32 mm, 44 mm, 56 mm, or the like.

[0018] After components are stored in the storage recess 3, the carrier tape 1 and the cover tape are adhered together, and the opening of the storage recess 3 is sealed, thereby forming a package.

[0019] Here, a method for manufacturing the carrier tape 1 according to the embodiment of the present invention will be described. Fig. 2 is a flow diagram showing a method for manufacturing the carrier tape 1 according to the embodiment of the present invention. Fig. 3 is a perspective view showing a take-up reel 10 on which the carrier tape 1 has been taken up.

[0020] The molding process S0 of the carrier tape 1 includes a preheating process S1 by a preheating section, a storage recess molding process S2 by a molding section, an intermittent conveying process S3 by an intermittent conveying section, a positioning process S4 by a positioning section, a feed hole punching process S5 by a punching section, and additionally a bottom hole drilling process S6 by a drilling section.

[0021] In the preheating step S1, a resin sheet for molding is preheated and softened, and the resin sheet is then guided to the next storage recess molding step S2.

[0022] In the storage recess forming step S2, the storage recess 3 is formed in the guided resin sheet.

[0023] In the intermittent conveying step S3, the resin sheet is conveyed along the conveying direction at an intermittent conveying pitch to the preheating step S1, the storage recess forming step S2, and the feed hole punching step S5 in that order.

[0024] In the positioning step S4, the storage recess 3 is used to perform positioning.

[0025] In the feed hole punching step S5, feed holes 2 are punched on the sides of the storage recess 3 in the resin sheet.

[0026] In the bottom hole punching step S6, a bottom hole 5 is punched in the center of the bottom surface of the storage recess 3. The bottom hole punching step S6 may be performed simultaneously in the punching section of the feed hole punching step S5, or may be performed in the punching section at a different timing.

[0027] Then, through the steps S1 to S6 of the forming step S0, the carrier tape 1 having the feed holes 2 and the storage recesses 3 is formed, and in the winding step S7, the carrier tape 1 is wound around the winding reel .

[0028] FIG. 3 is a perspective view showing the take-up reel 10 on which the carrier tape 1 has been taken up. The take-up reel 10 is composed of a central core portion (not shown) and flanges 11 provided on both ends of the core portion, and is designed to wind the carrier tape 1 in a spiral winding, but may also be wound in a record winding.

[0029] Thereafter, in this embodiment, an identification number assigning step S8 is performed in which an identification number (serial number, reel code) that is unique information is assigned to the take-up reel 10. However, this identification number assigning step S8 may be performed before the take-up reel 10 is mounted on the molding device for the carrier tape 1.

[0030] The identification number assigned to the take-up reel 10 does not have to be numbers, but may be other letters, symbols, or a combination thereof. Furthermore, the identification number does not have to be recognizable as letters by an operator, and may be an identifier that can be read by a reader, such as a barcode or two-dimensional code converted from the identification number. Alternatively, the identification number may be stored in an information storage medium that can be read by a reader via contact or contactless communication, such as an RF-ID or IC tag.

[0031] Here, the method of assigning the identification number, in the case of characters or the like, may be to print the identification number directly on flange 11 of take-up reel 10, or a printed label (sticker) may be affixed as identification means 12. If the identification number is stored in an information storage medium, it is preferable to affix or embed the information storage medium as identification means 12 in take-up reel 10.

[0032] Furthermore, in this embodiment, thereafter, in a storing step S9, one or more take-up reels 10 around which the carrier tape 1 has been wound are stored in a storage case 20.

[0033] Then, a second identification number assigning step S10 is performed to assign a second identification number (serial number, case code) that is information unique to each storage case 20. However, this second identification number assigning step S10 may be performed before storing the take-up reel 10 in the storage case 20.

[0034] The second identification number assigned to the storage case 20 may be numbers, letters, symbols, or a combination of these, similar to the identification number assigned to the take-up reel 10, or may be an identifier such as a barcode or two-dimensional code, or may be stored in an information storage medium such as an RF-ID or IC tag.

[0035] The second identification number may be assigned by direct printing, as in the case of the take-up reel 10, or a printed label may be attached as the second identification means 22. If the second identification number is stored in an information storage medium, the information storage medium may be attached to or embedded in the storage case 20 as the second identification means 22.

[0036] In this way, the carrier tape 1 (the take-up reel 10 and the storage case 20) is prepared for shipment. Note that multiple storage cases 20 may be packed on a pallet, or multiple pallets may be housed in a container. In this case, third and fourth identification numbers may be similarly assigned to each pallet or each container.

[0037] When the worker of the molding device finishes the manufacturing work of the carrier tape 1, he / she should prepare a daily work report (paper or electronic data) and store it in the management system 100 or the production management system 200. If the work report is prepared on paper, it should be converted into electronic data that can be recognized as images or characters.

[0038] FIG. 5 is an explanatory diagram showing an example of a daily work report. The daily work report should include the worker name, production date and time (time), manufacturing plant name, production line number, molding die name (mold code), product name (product code), material name (material code), reel name (reel code), manufacturing conditions, winding conditions, product output, lot number, defect record, etc. If the same combination occurs for a certain product (name), multiple items (for example, product name, molding die name, material name, etc.) can be combined into a single abbreviated symbol to simplify the description and reduce the data volume.

[0039] In addition, the worker inputs the identification number assigned to the take-up reel 10 and the second identification number assigned to the storage case 20 into the management system 100 described below, and the management system 100 stores these in the storage step S11.

[0040] Incidentally, a portion of the carrier tape 1 wound around the take-up reel 10 is extracted as a sample and stored and used for quality control purposes such as dimensional measurement and appearance inspection. The sample is managed using the same identification number as that assigned to the take-up reel 10.

[0041] 1, it is advisable to measure, for example, the length A0, width B0, and depth K0 of the storage recess 3, the diameter D0 of the feed hole 2, the distance E1 from the end face of the carrier tape 1 to the center of the feed hole 2, the distance F in the width direction from the center of the feed hole 2 to the center of the storage recess 3, the pitch P1 between adjacent storage recesses 3, the distance P2 in the longitudinal direction from the center of the feed hole 2 to the center of the storage recess 3, the width W, and thickness t of the carrier tape 1. After that, it is advisable to record the results of the dimension measurement on a dimension measurement sheet or input the data.

[0042] On the other hand, the appearance inspection may be performed by visually observing the shape (deformation) and scratches of the storage recess 3, and judging whether the product is good or bad. After that, the results of the appearance inspection may be entered in an appearance inspection form, or photographed and recorded as image data. The dimension measurement data and appearance inspection data may be stored in the management system 100 or the production management system 200 in a general-purpose data format such as a CSV file or JPEG.

[0043] Next, a management system 100 for controlling the quality of the carrier tape 1 will be described. FIG. 4 is a schematic diagram showing a management system 100 for the carrier tape 1 according to an embodiment of the present invention.

[0044] The management system 100 is composed of a computer (desktop PC, mobile terminal, cloud PC) or the like, and has an arithmetic unit 110, a memory unit 120, a communication unit 130, a display unit 140, an input unit 150, and an output unit 160.

[0045] The memory unit 120 is composed of an SSD, HDD, etc., and stores management programs that enable the computer (calculation unit 110) to function as the management system 100, other software, applications, etc., as well as various data such as image data and video data, tables, databases, etc.

[0046] The communication unit 130 enables wired or wireless data communication between the management system 100 and other personal computers. In this embodiment, the management system 100 can be connected to a higher-level production management system 200 in a manufacturing factory, control units 300 of multiple molding devices for the carrier tape 1, and the like via the communication unit 130.

[0047] The display unit 140 is configured with a monitor or the like, and is capable of displaying operation screens executed by various applications.

[0048] The input unit 150 is made up of a mouse, keyboard, etc., and allows input of characters, numbers, etc. on various applications, and is also used for inputting data into databases, etc.

[0049] The output unit 160 is configured with a printer, label printer, etc., and enables various applications to print operation screens, document data, image data, databases (lists), etc. onto paper. However, the output unit 160 may also record (copy) data onto a portable (portable) data storage medium such as a USB memory or CD-ROM.

[0050] The management system 100 can output data, tables, databases, etc. stored in the memory unit 120 to an external device such as the production management system 200 via the communication unit 130, or record (copy) and output the data on a portable storage medium such as a CD-ROM or USB memory.

[0051] The database stored in the memory unit 120 includes, for example, the identification number (and second identification number), the type and length of the carrier tape 1, the customer, the manufacturing date and time (time), the manufacturing line number, the manufacturing conditions, the worker's name, and other items entered in the daily work report, as well as various other items related to the carrier tape 1.

[0052] The calculation unit 110 can then extract some items from this database in accordance with instructions input by the worker, combine them with new items, and generate (or update) a new table (database), which can then be stored in the storage unit 120. Examples of such tables include a table linking identification numbers with second identification numbers, a table linking identification numbers with types of carrier tapes 1, a table linking identification numbers with current locations (e.g., shelf numbers in shipping warehouses, identification numbers of storage cases 20, pallets, containers, etc., truck vehicle numbers, already received at customer locations, currently in inspection process, etc.), and a table linking identification numbers with inspection records.

[0053] Furthermore, when generating a table linking identification numbers with inspection records, file names and file addresses may be added to the table items to link image data and video data captured during inspection with the daily work report (logbook).

[0054] These tables, databases, etc. can be printed as tables on the output unit 160 via an application, and can also be stored in the memory unit 120 in a general-purpose data format such as a CSV file, and data can also be transferred via the communication unit 130.

[0055] Furthermore, the output unit 160 may print the identification number and second identification number stored in the storage means 120 on labels as the identification means 12 and second identification means 22 to be affixed to the take-up reel 10 and the storage case 20, respectively.

[0056] The management system 100 for the carrier tape 1 can also be linked to a production management system 200 that manages the entire factory. In other words, the production management system 200 can manage the manufacturing processes S0 to S11 of the carrier tape 1 as a workflow. In this case, it is preferable to output data (database) including the identification number of the take-up reel 10 from the management system 100 to the production management system 200.

[0057] For example, when a customer places an order to wrap and pack the take-up reel 10 or storage case 20 before shipping, it is possible to record whether the packing work has been completed, and to grasp the production progress of the product at each process.

[0058] Finally, the concept of managing the carrier tape 1 using the management system 100 will be described. Fig. 6 is an explanatory diagram showing an example of a defect report. Fig. 7 is an explanatory diagram showing the management concept of the carrier tape 1 of the embodiment. Fig. 8 is an explanatory diagram showing the management concept of the conventional carrier tape 1. In Figs. 7 and 8, the diagonal shading indicates the management unit that can be extracted as a defective product.

[0059] If a defect occurs during the manufacturing process of the carrier tape 1, a defect report will be prepared. This defect report should include the date and time of occurrence, the location of occurrence, the lot number, the defect (problem) details, the cause, the countermeasures (proposed), the amount of defect, the name of the worker, etc. This defect report should also be stored as data in the management system 100 or the production management system 200.

[0060] Then, in the management system 100 or the production management system 200, a search is performed to determine whether there are any carrier tapes 1 with the same lot number as the defective lot number, and if there are any, one or more of them are identified.

[0061] However, in the conventional method of managing carrier tape 1, a second identification number was assigned to each storage case 20 that contained one or more take-up reels 10 (the lot number was linked to the second identification number of the storage case 20), so when a malfunction occurred, the carrier tape 1 to be enclosed could only be identified on a storage case 20 basis. Therefore, it was necessary to extract all of the carrier tapes 1 in the storage case 20 and dispose of them, such as by discarding them.

[0062] On the other hand, in the method of managing carrier tape 1 in this embodiment, an identification number is assigned to each winding reel 10 (the lot number is linked to the identification number of the winding reel 10), so that if a malfunction occurs, the winding reel 10 (i.e., the carrier tape 1) to be enclosed can be directly identified.

[0063] However, depending on the circumstances under which the malfunction occurs, the take-up reel 10 to be enclosed may not necessarily be one, but may be stored across multiple storage cases 20, but even in this case, it is possible to identify the take-up reel 10 in a specific storage case 20.

[0064] Furthermore, because the management system 100 links the identification number of the take-up reel 10 with the dimensional measurement data (CSV file) and visual inspection data, it is possible to easily obtain the dimensional measurement data and visual inspection data of the carrier tape 1 to be identified from the vast amount of past production history, which leads to a reduction in the number of steps required to address defects.

[0065] It should be noted that the above-mentioned identification method is performed on the management system 100 (screen), and the actual extraction (selection) work of the take-up reel 10 involves identifying the storage case 20, which is a higher-level shipping form, and then identifying the take-up reel 10 inside the storage case 20. Therefore, it is desirable to assign second to fourth identification numbers, etc., depending on the shipping form, in order to quickly identify the current location of the carrier tape 1, etc.

[0066] In this way, some of the steps in the manufacturing method of the carrier tape 1 and each step in the management method of the carrier tape 1 may be configured as steps of a management program, and the functions may be realized by a computer (the calculation unit 110 thereof).

[0067] As described above, the manufacturing method of the carrier tape 1 according to the embodiment of the present invention includes a winding step S7 in which the carrier tape 1, which has the sprocket holes 2 and the storage recesses 3 molded in a resin sheet, is wound around the take-up reel 10, and an identification number assigning step S8 in which a unique identification number is assigned to each take-up reel 10 around which the carrier tape 1 is wound. This allows the carrier tape 1 to be identified and managed for each take-up reel 10. This makes it possible to ascertain the manufacturing order, which could not be identified using the conventional management method in units of storage cases 20, and also allows for the take-up reel 10 to be enclosed when performing traceability due to product complaints or the like.

[0068] The manufacturing method of the carrier tape 1 of the embodiment includes a storage step S11 of storing the identification number in the storage unit 120 of the computer. This allows the carrier tape 1 to be managed by the computer.

[0069] The manufacturing method of the carrier tape 1 of the embodiment includes a storing step S9 of storing one or more take-up reels 10 in a storage case 20, and a second identification number assigning step S10 of assigning a unique identification number to each storage case. This allows the carrier tape 1 to be managed for each take-up reel 10, and also for each storage case 20 that stores one or more take-up reels 10. Therefore, the carrier tape 1 can be identified from a higher-level shipping form.

[0070] The carrier tape 1 management system 100 of an embodiment of the present invention includes a memory unit 120 that stores a unique identification number assigned to each winding reel 10 that has wound up the carrier tape 1, and manages the carrier tape 1 based on the identification number stored in the memory unit 120. The method for managing the carrier tape 1 according to the embodiment of the present invention includes a storage step S11 of storing a unique identification number assigned to each take-up reel 10 that takes up the carrier tape 1 in the storage unit 120 of the computer. The management program for the carrier tape 1 according to the embodiment of the present invention causes a computer to realize a storage function for storing a unique identification number assigned to each take-up reel 10 onto which the carrier tape 1 is taken up. This allows the carrier tape 1 to be identified and managed for each take-up reel 10 by a computer.

[0071] The storage unit 120 of the embodiment stores the identification number in association with at least one of the type of carrier tape 1, the current location of the carrier tape 1, and the inspection record of the carrier tape 1. This makes it possible to easily check and collect information by associating the carrier tape 1 with various information.

[0072] The management system 100 of the embodiment outputs a data table including the identification numbers stored in the storage unit 120 to a production management system 200 that manages the workflow in the manufacturing process of the carrier tape 1. As a result, progress management can be performed by linking information such as the worker, time, and location with the identification number of the take-up reel 10 in each manufacturing process S0 to S11 that manufactures the carrier tape 1. Furthermore, by setting a workflow for each carrier tape 1, it becomes possible to confirm and verify whether the manufacturing is being carried out in accordance with that workflow. For example, if some steps in the workflow are skipped, an alert can be issued to call attention, preventing the delivery of products that differ from the order, or defective or abnormal products to customers.

[0073] Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and changes are possible within the scope of the gist of the present invention as set forth in the claims.
