Description

  The present invention relates to a method of manufacturing a flat display device and other electronic / electrical products, and a container for the same. Here, the term electronic / electrical product includes not only final products but also intermediate products or semi-finished products and various electronic / electrical components. For example, a display panel, a light guide plate, a thin semiconductor chip, a printed wiring board, and the like of a small size (panel diagonal size: 1 to 3 inches) or a medium size (panel diagonal size: 4 to 10 inches) are included.

  In recent years, the market of flat display devices such as liquid crystal display devices has been rapidly expanding. In particular, the market for small and medium-sized flat display devices used for mobile phones, personal digital assistants (PDAs), car navigation devices, and the like is rapidly expanding.

  In manufacturing such a flat display device, after creating the display panel body, a display panel with a connection board is created by attaching a connection board such as a flexible printed circuit board (FPC), and then, A display panel module is created by combining a surface light source device and the like. This display panel module is incorporated into a final consumer product such as a mobile phone. The creation of the display panel, the creation of the display panel module, and the creation of the final consumption product from the display panel module are often performed in separate manufacturing facilities or sites. Also, the creation of a display panel (display panel body) before mounting the connection board and the mounting of the connection board are often performed in separate facilities or sites. Therefore, the display panel or the display panel module is transported between them.

  In general, a transfer tray having a plurality of storage portions is used for transferring a display panel or the like (Patent Documents 1 to 3). For example, storage recesses are formed in a matrix on the top surface of a flat, flat transport tray having elasticity, and one display panel is stably fitted and held in these recesses (Patent Document 1). In this way, damage to the display panel due to vibration or impact is prevented even when transported by truck, railway or aircraft. Further, the display panel or the like is prevented from coming out of the housing recess due to vibration or impact (for example, Patent Document 2).

On the other hand, for finer parts such as semiconductor packages, various storage / conveying methods using a belt-like carrier tape have been studied (Patent Documents 4 to 5). The carrier tape is a belt-shaped plastic film provided with recesses for storage at regular intervals in a row. If necessary, a cover film is used to seal fine components such as a semiconductor package held in the edge of the carrier tape and each recess for storage (Patent Document 4). The recess for storage is provided by embossing (Patent Document 4) or by punching the base film to form a recess and then bonding the backing film (Patent Document 5).
JP2002-332023 JP2004-018094 JP 2002-337951 A JP2003-095216 JP 2001-348008 A

  According to the conventional technique using a transport tray or a carrier tape, the size of the storage recess needs to substantially match the size of the electronic / electric product. For this reason, it is necessary to prepare a storage recess having a different dimension each time the type of electronic / electrical product is switched.

  Further, the carrier tape is designed so as to be applicable only to fine parts, and it is difficult to provide a buffering action or the like. Therefore, for electronic / electrical products having a relatively large size and a high possibility of breakage such as a display panel, no other suitable method could be considered other than using a transport tray.

  However, when transport is performed using a transport tray, the edge of the display panel wears the holding surface of the transport tray due to vibration or impact during transportation, causing dust generation. For example, when transporting a display panel module from a display panel production site to a final consumption product production site using a transport tray, in order to reuse the transport tray without discarding it, an empty transport tray is used. Had to be sent back to the production area of the display panel module. In particular, since the transport tray cannot be folded or compressed, a large space occupies the load when returning and the transportation cost is increased.

Furthermore, when a transport tray is used, sealing is relatively difficult, and it has not always been easy to prevent fine dust and moisture from entering. For example, it has been necessary to perform an operation of sealing and stacking a stack of transport trays with a thick resin sheet.
The present inventor made various attempts to search for a storage material to replace the transport tray in the intensive study in view of the above problems. In particular, use cushioning materials so that cracks and chips do not occur in the display panel, and use foam materials and laminated composite sheets to meet the difficult demands of keeping the display panel from being misaligned. investigated.

  While continuing diligent study, we came to an attempt by a simple method of sandwiching a display panel between flat general-purpose resin sheets and appropriately heat-sealing the sheets. Then, surprisingly, it became possible to hold the display panel and protect it from impacts depending on conditions. Further, it has been known that, as with the carrier tape, it is also possible to produce a belt-like storage body and to wrap it around the reel or supply it while being fed out from the reel.

  As described above, the present invention can deal with a change in dimensions of an electronic / electrical product quickly and at low cost in a method for manufacturing a flat panel display device or other electronic / electrical product and a container for the same. At the same time, it is intended to provide a device that can prevent damage to electronic and electrical products and generation of dust, and can reduce the cost for collecting the storage body.

  The method for producing an electronic / electric product according to the present invention is such that the first flat electronic / electric product is sequentially sandwiched between flat belt-shaped resin sheets and arranged along the longitudinal direction of the resin sheet. The resin sheets are fused or bonded together so as to form one storage portion for each piece, and a joining portion is provided, whereby a large number of the first electronic / electrical products are arranged in a longitudinal direction. Creating a stored strip-shaped storage body, and thereafter storing or transporting the first electronic / electrical product in the state of the strip-shaped storage body to be used for manufacturing a second electronic / electrical product, The resin sheet is provided with a predetermined breakage portion on at least one surface of the belt-like storage body, and the predetermined breakage portion is formed by a notch that forms a through hole or a recess, and each notch is a direction or line extending from the predetermined breakage portion. Long in the width direction It is in the form of a square, a square, or a trapezoid, and by sequentially separating the resin sheets, the storage units are sequentially opened, and the first electronic / electrical products are sequentially It is taken out by this.

  Here, as described in the technical field section of this specification, the term “electronic / electric product” refers to various products and intermediate products included in the electronic / electric field, as well as various parts, devices, and members incorporated therein. Shall be included. In addition, the term “resin sheet” includes not only a sheet having a large thickness but also all those generally called a film or a sheet as long as it is made of resin.

  The band-shaped storage body for electronic / electrical products according to the present invention is a storage unit in which flat electronic / electrical products are arranged in one or a plurality of rows between flat belt-shaped resin sheets, and each of the electronic / electrical products is stored. Is formed by a joining portion that joins the resin sheets by fusion or adhesion, and each electronic / electrical product is held at a predetermined position by the joining portion, and the resin sheet is placed on both sides of the row of the storage portions. Ear portions are formed, and at least one surface of the belt-like storage body, the resin sheet is provided with a predetermined break portion, and the predetermined break portion is formed by a notch that forms a through hole or a recess, and each notch The shape is a rectangle that is long in the extending direction or the line width direction of the predetermined breakage point, or a square shape, a dogleg shape, or a trapezoidal shape.

  Costs for storing or transporting electronic / electrical products can be reduced, and generation of damage and dust can be prevented.

  The resin sheet forming the band-shaped container has a certain degree of tensile strength, toughness, durability and flexibility, and can be fused or bonded. Any of them can be used. In order to be able to be fused, it is preferably made of a thermoplastic resin, but may be a laminated sheet including a thermoplastic fused layer. Moreover, what is necessary is just a sheet | seat provided with appropriate adhesiveness, when joining using an adhesive agent. For example, a sheet that has been roughened or polarized by surface treatment can be used. In addition, the resin sheet may be made of an elastomer resin or a flexible foamed resin depending on circumstances.

  The resin sheet preferably has a transparent sheet portion on at least one side of the belt-like storage body. More preferably, both sheet portions are transparent. Thereby, the kind and property of the packaged electric / electronic product can be easily confirmed. For example, it is possible to read a production lot number or a product name engraved on an electric / electronic product without opening it. In addition, it is possible to easily catch defects such as damage to the outer shape. When only one side of the resin sheet is a transparent sheet, the other side can be a foamable sheet.

  In the resin sheet, preferably, a sheet portion on at least one surface of the belt-like storage body has antistatic properties. The entire resin layer constituting the sheet portion may be blended with an antistatic material, or an antistatic layer may be formed on the surface. By imparting antistatic properties in this way, it is possible to prevent undesired generation of static electricity and damage to electronic and electrical products due to this in each step of packaging, transporting and taking out. The antistatic property can be imparted, for example, by providing a transparent conductive layer in which conductive fine particles made of antimony recovery oxide, indium-doped tin oxide (ITO) or zinc oxide (IZO) are dispersed. . In some cases, the antistatic layer can be formed of non-transparent particles such as conductive carbon particles.

  Specific examples of the resin sheet forming the belt-like storage body include those described in JP-A-9-175592. That is, a low-density polyethylene or an ethylene / unsaturated ester copolymer as a base layer and a potassium / ionomer layer of an ethylene / unsaturated ester copolymer provided on one surface can be used. This ionomer forms a sealing layer that can be easily fused and peeled, and plays a role of antistatic.

  The fusion for providing the joint may be performed by a general method such as ultrasonic fusion (= ultrasonic sealing or ultrasonic welding), impulse heat sealing, or the like. it can. Moreover, when joining by adhesion | attachment, a reactive or non-reactive hot-melt-adhesive or various general adhesives for plastics can be used.

  In a preferred embodiment, the sheet portion forming the front side surface and the back side surface of the belt-shaped storage body is made of the same material, and in a particularly preferable content, a single belt-shaped resin sheet extends along a portion near the center line. It is composed by bending. In such a case, it is easy to provide the fusibility, and it becomes easier to supply, collect and other operations of the resin sheet.

  In the case of a non-foaming sheet, the thickness of the resin sheet is typically 10 to 300 μm, particularly about 30 to 80 μm.

  The electronic / electrical products stored in the band-shaped storage body are flat. That is, the ratio of thickness to longitudinal and lateral dimensions is fairly small, at least 1/5 or less, usually about 1/10 to 1/100. The shape is not limited to a flat plate or a flexible sheet. For example, a large number of small components mounted on a substrate may be used, and in some cases, a plate-shaped article having a slight curvature may be used.

  In the band-shaped storage body, preferably, the same type of electronic / electrical products are arranged at almost equal intervals, and one by one is stored and held in the corresponding storage section. However, in some cases, two or more types of electronic / electrical products can be stored in a certain order, and the interval can be adjusted as appropriate. For example, the interval between the storage units can be increased where the production lot is switched. In addition, a series of members for manufacturing one electronic / electric product can be stored as a kit in a series of storage units. In addition, when the size of the electronic / electrical product is small, for example, 3 inches or less, and the front side and the back side sheet portions are provided by separate sheets, two or three rows extending in the longitudinal direction of the belt-like storage body are formed. It is also possible to provide a storage part.

  When each storage part of a strip | belt-shaped storage body is formed by joining, Preferably, positioning about the electronic / electrical product stored is performed. That is, the electronic / electrical product arranged on the resin sheet is held at the predetermined position while further adjusting the position to the predetermined position. For example, the tension by the resin sheet is applied to the ridges and corners of the electronic / electrical product, so that the electronic / electrical product is held so as not to be misaligned with respect to the resin sheet. In the case where a slight positional deviation with respect to the width direction of the resin sheet is allowed, it is possible to perform positioning and non-displaceable holding in the longitudinal direction of the resin sheet at the time of joining.

  A flat electronic / electrical product in which the band-shaped container of the present invention is particularly suitable includes a display panel before or after mounting a connection board. In particular, the diagonal dimension of the display area is 10 inches or less, preferably A display panel of 8 inches or less, more preferably 4 inches or less can be used. The display panel is typically a liquid crystal display panel, but the same applies to organic EL, inorganic EL, and others. The display panel is made of a substrate that is relatively easily damaged, such as a glass substrate. Other examples of flat electronic / electrical products are a surface light source device for a flat display device, a light guide plate, or a drive circuit board, etc., and the outer dimensions are substantially equal to the above display panel, that is, The thing of the dimension corresponding to a medium-sized display panel can be mentioned.

  The belt-like storage body is preferably provided with ears made of a resin sheet on both sides of the storage unit row. The ear portion serves as a cushioning material that protects the storage portion when the belt-like storage body is wound or folded.

  When taking out the electronic / electrical product from the belt-like storage body, it is necessary to open the storage part, and it is preferable that the electronic / electrical product can be sequentially taken out in order to sequentially supply the electronic / electrical product. For this reason, according to a preferable aspect, the strip-shaped storage body can be easily peeled off by applying an appropriate stress so as to separate the front side sheet portion and the back side sheet portion of the strip-shaped storage body from each other. Further, according to another preferred embodiment, the front side sheet portion is provided with a predetermined breaking portion along one edge of the belt-shaped storage body, and sequentially tears from the front end side of the belt-shaped storage body to sequentially open the storage portions. be able to.

  In the case of facilitating removal by the peelable joint portion, a double-edge ear portion in which the edges of the resin sheets are overlapped in a non-joined state is preferably provided outside the row of the storage portions. And it can peel easily by pulling apart the edge parts of the resin sheet which makes the ear | edge part of a double edge. In addition, by opening only one storage part at an arbitrary position in the middle of the belt-shaped storage body from the double-edge part, it is possible to extract electronic / electrical products and perform various inspections. For example, a display performance test called a lighting test can be performed on the display panel module. In addition, in the double edged ear part, the edge part of one sheet part preferably protrudes outward from the edge part of the other sheet part in order to make the separation operation easier.

  In the case where the removal is facilitated by the planned breakage portion, the predetermined breakage portion is preferably provided only on one sheet portion, preferably on the transparent front side sheet portion. The predetermined breaking portion is preferably formed so as to be able to be broken by an appropriate stress to be pulled away from both sides so that only one storage portion can be easily opened at a middle portion of the belt-shaped storage body. For example, the predetermined breakage point can be provided such that an opening is provided in a broken line shape or a dotted line shape, or a portion cut into a cross-sectional notch shape extends linearly.

  In addition, by adopting a method of sequentially storing in the strip-shaped storage body and taking out sequentially as described above, it is not necessary to provide a storage location such as a transport tray or a take-out mechanism in the vicinity of the assembly location. Further, since the packaging can be performed as soon as the assembly is completed, and it can be taken out immediately before the next assembly, the adhesion of dust and the like can be minimized.

  According to a preferred embodiment, the supply of electronic / electrical products between the resin sheets in forming the band-shaped storage body is performed in a state where the resin sheet is bent in a V-shaped cross section and opened upward. It is performed by dropping or sliding into the gap having a V-shaped cross section. At this time, the resin sheet is arranged at a predetermined position in the width direction by an appropriate locking action so as not to reach the bottom of the V-shaped cross section.

  Further, according to a preferred embodiment for forming the band-shaped storage body, the pocket portion is provided in advance by appropriately fusing the front-side sheet portion and the back-side sheet portion of the flat band-shaped resin sheet. A packaging device for manufacturing a belt-like storage body includes a horizontal feeding portion and a vertical feeding portion, and in the horizontal feeding portion, for example, a display panel for a mobile phone is opened while the opening side of the pocket portion is opened by a sheet opening guide. , Insert into the pocket part sequentially. The transition from the horizontal feed unit to the vertical feed unit is performed along a curved plate having a curved surface having a constant path length and having a cutout at the center. In the vertical feed portion, the pocket portion is appropriately closed by the heat seal portion.

  Thus, the installation space of a packing device can be made small by combining a horizontal feed part and a vertical feed part. Further, if the pocket portion is closed while feeding the sheet in the vertical direction, the resin sheet is sufficiently stretched, and sealing without wrinkles or distortion is possible.

  Further, according to a preferred embodiment of the belt-like storage body, a predetermined number of empty storage portions are provided, and the belt-shaped storage body can be folded in a zigzag shape or a winding shape by being bent at the locations of the empty storage portions. Moreover, the lead | read | reed part of the form in which the empty storage part continued or the form which does not provide a junction part between the front and back sheet | seat parts can be provided in the front-end | tip of a strip | belt-shaped storage body.

  According to a preferred embodiment, the belt-like storage body is spirally wound as it is or around a buffer core, and stored or transported in this state. Moreover, according to another preferable aspect, storage or transport is performed in a state of being alternately folded in a wave shape. In these storage states, the air or other gas in each storage part can also perform a buffering action.

  When folded alternately in a wave shape, according to a preferred embodiment, a plurality of small chambers are provided inside a storage case such as a cardboard box, and the small chambers are separated from the outer wall and the adjacent small chambers by a buffering gap or a buffer material layer. Separated.

  According to a preferable aspect, the storage section in the belt-shaped storage body is shielded from the outside air and sealed, thereby protecting the internal electronic and electrical products from the ingress of dust and moisture. The storage portions to be sealed at the time of joining can be independent sealing portions, or can be communicated with each other by an appropriate communication portion.

  At the time of sealing, the inside can be replaced with an inert gas such as nitrogen or carbon dioxide gas. Alternatively, oxygen can be eliminated by reducing the pressure inside the storage portion. For example, it can be sealed in a decompression chamber so as to be in close contact with the outer surface of an electronic / electric product in which a resin sheet is stored under atmospheric pressure. Moreover, when sealing the storage part of a strip | belt-shaped storage body, a hygroscopic agent, an oxygen scavenger, etc. can also be arrange | positioned inside. For example, a hygroscopic layer can be formed by providing a polyvinyl alcohol layer on the inner surface of the resin sheet.

  A series of members, for example, a display panel main body, a frame, and a connection substrate can be stored in one strip-shaped storage body so as to be repeated in this order. Moreover, these members can be stored in each strip-shaped storage body, and each can be stored in a small chamber in one cardboard box.

  According to another preferred embodiment, the storage part in the belt-like storage body has the opening of the pocket part opened so that the electronic / electrical product can be taken out and reinserted. That is, the insertion opening for inserting the electronic / electrical product remains open. With such an embodiment, for example, when an electronic / electric product is transported between nearby locations, a belt-like sheet with a storage unit can be used repeatedly. Also, with such a belt-like container, it is charged into an autoclave, a reaction vessel, a processing chamber, etc., and subjected to decompression, pressurization, heating, cooling, compression, hot air treatment, gas replacement, aging, cleaning, and other processing. be able to. That is, a belt-like sheet with a storage portion can be used as a “passing container” instead of a cassette case.

  In this way, when electronic / electrical products are repeatedly used or used as a holder during processing, those made of a resin having high durability or heat resistance are desirable. For example, in addition to the polyethylene (PE) resin exemplified above, polypropylene, polymethylpentene, etc. having higher heat resistance can also be used. Further, as a resin having higher durability and heat resistance, polyethylene terephthalate (PET), polyethylene naphthalate, or the like can be used. In some cases, ethylene / tetrafluoroethylene (ETFE), fluoroethylene / propylene (FEP), etc. The fluororesin can also be used. In order to impart antistatic properties to the sheet made of these resins, a mesh layer made of conductive fibers may be laminated.

  If necessary, the resin sheet that makes up the band-shaped package will have the model, product type, production lot, date of production, production location, destination, destination model, or handling precautions for the electronic / electrical product to be stored. Characters or symbols for indicating such information can be printed. For example, instead of engraving or labeling electronic / electrical products themselves, the necessary information and precautions are indicated by bar codes, warning symbols, character strings, etc. -It can be read when taking out electrical products.

  The band-like container and the packaging method as described above can be used simply for shipping intermediate products or final products. By such a packaging method, it is possible to perform packaging sequentially without delay from the completion of the product, and it is possible to sequentially take out and use or sell at the shipping destination.

  The electronic / electric product can be taken out from the belt-shaped package as described above by hand, or by a general-purpose robot apparatus. However, by using an unpacking device as described below, workability can be improved and the risk of damage to electronic and electrical products due to the cause of accidental dropping can be reduced.

  The unpacking device accepts the belt-like storage body from one side by continuous or intermittent driving, and breaks, peels or cuts the resin sheet along a specific line to move each storage part of the belt-like storage body. Open sequentially. Then, one or a plurality of electronic / electrical products can be supplied to the next process by handing means such as a hand or a robot arm.

  According to one preferred embodiment, a planned breaking portion or a planned peeling portion is provided along both edges of the belt-like storage body. The unpacking device is an electronic / electrical product that unpacks and stores the belt-like storage body by capturing the front side sheet part or part thereof and the back side sheet part or part thereof and separating them sequentially in the reverse direction. Can be taken out.
