取出装置Extraction device
　本発明は、液晶表示パネル等に採用される平板状の樹脂成形品を吸着して取出し可能な取出装置に関し、特に、金型に張り付いている樹脂成形品たる導光板を金型から離型するとき、取出した導光板に変形が発生することを防止することができる、導光板の取出しに適した取出装置に関する。 The present invention relates to a take-out device capable of adsorbing and taking out a flat resin molded product employed in a liquid crystal display panel or the like, and in particular, releasing a light guide plate as a resin molded product attached to a mold from the mold. The present invention relates to a take-out device suitable for taking out a light guide plate, which can prevent deformation of the taken out light guide plate.
　近年、液晶等の表示モニターには、光を均一に面発光するために導光板が採用されている。こうした導光板には、板材の一方面においては光を反射させる集光パターンが、他方面には正面に光を集めて輝度を向上させる拡散パターンが設けられている。導光板等の樹脂成形品は、射出成形機の金型により成形されることが一般的であるが、こうした樹脂成形品を金型から離型するときなどに、反りや、不均一な温度変化が生じると、製品としての品質に悪影響を及ぼすことがあるため、このような問題を防止することが望まれている。 In recent years, a light guide plate has been adopted in a display monitor such as a liquid crystal in order to uniformly emit light. Such a light guide plate is provided with a light condensing pattern for reflecting light on one surface of the plate material and a diffusion pattern for collecting light on the front surface to improve luminance on the other surface. In general, resin molded products such as light guide plates are molded by the mold of an injection molding machine, but when such resin molded products are released from the mold, warping and uneven temperature changes If this occurs, the quality of the product may be adversely affected. Therefore, it is desired to prevent such a problem.
　図３、図４は従来から用いられている導光版を吸着して保持する取出装置の概略構成を示し、前者は背面図、後者は側面図である。同図に示す取出装置１００においては、導光板１０１を負圧吸引力により吸着するための比較的大きめな吸盤１０２が９個ベース１０３に設けられており、金型に張り付いている導光板１０１を離型するときには、１枚の導光板１０１に対し９個の吸盤１０２を吸着して当該導光板１０１の取出しが行なわれる。こうした技術に関連するものとして、特許文献１（明細書段落［００３２］、［００３５］、図２、図４、５、）には、導光板を吸着するための吸盤を複数備えた成形装置が開示されている。 3 and 4 show a schematic configuration of a take-out device that sucks and holds a light guide plate that has been conventionally used, the former being a rear view and the latter being a side view. In the take-out device 100 shown in the figure, nine relatively large suction cups 102 for adsorbing the light guide plate 101 with negative pressure suction force are provided on the base 103, and the light guide plate 101 attached to the mold. When the mold is released, nine suction cups 102 are adsorbed to one light guide plate 101 and the light guide plate 101 is taken out. As related to such a technique, Patent Document 1 (specifications paragraphs [0032], [0035], FIG. 2, FIG. 4, 5,) includes a molding apparatus including a plurality of suction cups for adsorbing a light guide plate. It is disclosed.

　図３及び図４や特許文献１で開示されている、複数の吸盤１０２により単独の導光板１０１を吸着しようという技術においては、吸引力が発生する吸盤１０２の当接される部分と、吸引力が発生しない吸盤の当接されない部分とでは、吸盤１０２を導光板１０１に吸着させたとき、当該導光板１０１に対する応力に差が生じることから反りが発生する。また、金型による成形直後に当該金型から６０℃～７０℃の導光板１０１を取出すため、導光板１０１に対し吸盤１０２を吸着させると、吸盤１０２で吸着されている部分と、吸着されていない部分とに温度差が生じ、温度差に伴う収縮差により導光板に変形が発生してしまうことがあった。 In the technique of sucking the single light guide plate 101 by the plurality of suction cups 102 disclosed in FIG. 3 and FIG. 4 and Patent Document 1, the portion where the suction cup 102 abuts and the suction force generated. When the suction cup 102 is adsorbed to the light guide plate 101, a warp occurs due to a difference in stress applied to the light guide plate 101. Further, since the light guide plate 101 having a temperature of 60 ° C. to 70 ° C. is taken out from the mold immediately after molding by the mold, when the suction cup 102 is sucked to the light guide plate 101, the portion sucked by the suction cup 102 is sucked. There was a temperature difference between the unexposed portion and a deformation of the light guide plate due to a shrinkage difference caused by the temperature difference.
　本発明は、上記課題に鑑みてなされたものであり、導光板等の平板状の樹脂成形品を吸着して取出す際、当該樹脂成形品等が変形してしまうことを抑止することができる取出装置を提供することを目的とする。 The present invention has been made in view of the above-described problems, and is capable of suppressing deformation of the resin molded product or the like when the flat resin molded product such as a light guide plate is adsorbed and taken out. An object is to provide an apparatus.

　本取出装置の発明において、
　前記樹脂成形品又は前記板材は、平板状の導光板であることを特徴とする。 In the invention of the take-out device,
The resin molded product or the plate material is a flat light guide plate.
　本取出装置の発明によれば、樹脂成形品である平板の導光板を金型から取出すに際し、弾性を有し、複数の微細孔が形成されている連通多孔材である吸着体により、導光板の片面全体を吸着することができるので、導光板全体の温度を均一的に保つことができ、さらに、吸着体で導光板を吸着したときに、当該導光板に対する応力を均一化することができる。よって、従来のような、複数の吸盤により単独の導光板を吸着しようという技術においては、吸引力が発生する吸盤の当接される部分と、吸引力が発生しない吸盤の当接されない部分とでは、導光板に対する応力に差が生じることから反りが発生したり、或いは、６０℃～７０℃の導光板を金型から取出すときに、導光板に対し吸盤を吸着させると、吸盤で吸着されている部分と、吸着されていない部分とに温度差が生じ、温度差に伴う収縮差により導光板に変形が発生してしまうことがあったが、こうした不具合を解消することができる。 According to the present invention of the take-out device, when the flat light guide plate, which is a resin molded product, is taken out from the mold, the light guide plate is provided by the adsorbent that is a continuous porous material having elasticity and having a plurality of fine holes. Since the entire surface of the light guide plate can be adsorbed, the temperature of the entire light guide plate can be kept uniform, and when the light guide plate is adsorbed by the adsorber, the stress on the light guide plate can be made uniform. . Therefore, in the conventional technique of attracting a single light guide plate with a plurality of suction cups, there are a portion where the suction cup where the suction force is generated and a portion where the suction cup where the suction force is not generated are not contacted. When the light guide plate at 60 ° C. to 70 ° C. is taken out from the mold, if the suction cup is adsorbed to the light guide plate, it will be adsorbed by the suction cup. There is a temperature difference between the portion that is not attracted and the portion that is not attracted, and the light guide plate may be deformed due to the shrinkage difference caused by the temperature difference. However, such a problem can be solved.

　以下、本発明の実施形態を図１及び図２により以下に説明する。もちろん、本発明は、その発明の趣旨に反しない範囲で実施形態において説明した以外の構成のものに対しても容易に適用可能なことは説明を要するまでもない。 Hereinafter, embodiments of the present invention will be described below with reference to FIGS. 1 and 2. Of course, it is needless to say that the present invention can be easily applied to configurations other than those described in the embodiments without departing from the spirit of the invention.
　図１及び図２に示す本発明の一例の取出装置１は、射出成形機の金型に張り付いている、６０℃～７０℃の平板状の比較的肉厚の薄い（０．１ｍｍ～０．５ｍｍ程度）樹脂成形品たる導光板２を取出す（離型）ときに用いられるものである。 The take-out device 1 of the present invention shown in FIGS. 1 and 2 is attached to a mold of an injection molding machine and is a flat plate of 60 ° C. to 70 ° C. having a relatively thin thickness (0.1 mm to 0 mm). .About.5 mm) This is used when the light guide plate 2 as a resin molded product is taken out (released).
　取出装置１には、平板状の導光板２の片面全面を吸着する吸着体３と、吸着体３で導光板２を吸着するときに吸引力を発生させる負圧発生手段たる真空ポンプ４と、吸着体３を保持する吸引ブロック材５、吸引ブロック材５を保持するベース６と、アーム７とを備える。 The take-out device 1 includes an adsorbent 3 that adsorbs the entire surface of one surface of a flat light guide plate 2, a vacuum pump 4 that serves as a negative pressure generating means that generates a suction force when adsorbing the light guide plate 2 with the adsorbent 3, and A suction block member 5 that holds the adsorbent 3, a base 6 that holds the suction block member 5, and an arm 7 are provided.
　吸着体３には、導光板２の片面全体を当接させて吸着することができる吸着面３ａを一方面に有し、その反対側である他方面３ｂ側の縁部は吸引ブロック材５に一体に固定され、ベース６の内面と吸引ブロック材５の内面とで囲まれた部分に空間部（真空室）８を有する。 The adsorbent 3 has an adsorbing surface 3 a that can adsorb and adsorb the entire surface of the light guide plate 2 on one side, and the edge on the other surface 3 b side opposite to the adsorbing surface 3 a. A space (vacuum chamber) 8 is provided in a portion fixed integrally and surrounded by the inner surface of the base 6 and the inner surface of the suction block member 5.
　また、吸引ブロック材５には、図２に示すように、等間隔に複数の貫通孔９が形成されており、この貫通孔９は、前記空間部８と吸引ブロック材５の外側とを連通するようにして形成されている。 Further, as shown in FIG. 2, the suction block member 5 has a plurality of through holes 9 formed at equal intervals. The through holes 9 communicate the space 8 and the outside of the suction block member 5. It is formed like this.
　吸引ブロック材５の外側には、吸引ブロック材５に形成された貫通孔９を全て覆うようにして吸着体３が装着されている。この吸着体３は、連通多孔材であり、本実施形態では、直径が、１ｍｍ以下、より詳しくは、０．５ｍｍ以下、さらに詳しくは、１０μｍ～５００μｍ（０．５ｍｍ）程度の微細孔が多数形成された弾性を有する連通多孔材（例えばシリコンゴム、ウレタンゴム）であり、独立発泡材とは相違しており、連通多孔材の孔径よりも吸引ブロック材５の貫通孔９の孔径は大きく形成する。 The adsorbent 3 is mounted outside the suction block material 5 so as to cover all the through holes 9 formed in the suction block material 5. The adsorbent 3 is a continuous porous material. In this embodiment, the adsorbent 3 has a large number of fine pores having a diameter of 1 mm or less, more specifically 0.5 mm or less, and more specifically 10 μm to 500 μm (0.5 mm). It is a formed continuous porous material (for example, silicon rubber, urethane rubber) having elasticity, which is different from the independent foam material, and the hole diameter of the through hole 9 of the suction block material 5 is larger than the hole diameter of the continuous porous material. To do.
　また、真空ポンプ４は、管体１０を通じてベース６に接続されており、真空ポンプ４を駆動することにより、ベース６の内面と吸引ブロック材５の内面とで形成された空間部８に負圧が発生される。そして、その負圧を用いて、取出装置１の外側に有する外気を、吸着体３の孔、吸引ブロック材５の貫通孔９を通じ吸引し、吸着体３の外側面である吸着面３ａに当接されている、金型に張り付いている導光板２を吸引し保持される。そして、アーム７を介して、取出装置１に設けた図示しない搬送手段により、吸着体３で吸着した導光板２を所定位置等に搬送することが可能となる。 Further, the vacuum pump 4 is connected to the base 6 through the tube body 10, and by driving the vacuum pump 4, a negative pressure is applied to the space portion 8 formed by the inner surface of the base 6 and the inner surface of the suction block material 5. Is generated. Then, using the negative pressure, the outside air outside the take-out device 1 is sucked through the holes of the adsorber 3 and the through-holes 9 of the suction block material 5 and hits the adsorbing surface 3a which is the outer surface of the adsorbing body 3. The light guide plate 2 that is in contact with the mold and attached to the mold is sucked and held. Then, the light guide plate 2 adsorbed by the adsorbing body 3 can be conveyed to a predetermined position or the like by the conveying means (not shown) provided in the take-out device 1 via the arm 7.
　以上のように本取出装置１によれば、樹脂成形品としての導光板２を吸着体３で吸着して、金型から取出す際、単独の導光板２の片面全体に亘って、単独の吸着体３を当接させ吸着して取出すことができる。よって、従来のような、複数の吸盤により単独の導光板を吸着しようという技術においては、吸引力が発生する吸盤の当接される部分と、吸引力が発生しない吸盤の当接されない部分とで、導光板に対する応力に差が生じることから反りが発生したり、或いは、６０℃～７０℃の導光板を金型から取出すときに、導光板に対し吸盤を吸着させると、吸盤で吸着されている部分と、吸着されていない部分とに温度差が生じ、温度差に伴う収縮差により導光板に変形が発生してしまうことがあったが、こうした不具合を解消することができる。 As described above, according to the take-out device 1, when the light guide plate 2 as a resin molded product is adsorbed by the adsorbent 3 and taken out from the mold, the single adsorbing is performed over the entire surface of the single light guide plate 2. The body 3 can be brought into contact with and adsorbed and taken out. Therefore, in the conventional technique of attracting a single light guide plate with a plurality of suction cups, there are a portion where the suction cup where the suction force is generated and a portion where the suction cup where the suction force is not generated are contacted. When the light guide plate at 60 ° C. to 70 ° C. is taken out from the mold, if the suction cup is adsorbed to the light guide plate, it will be adsorbed by the suction cup. There is a temperature difference between the portion that is not attracted and the portion that is not attracted, and the light guide plate may be deformed due to the shrinkage difference caused by the temperature difference. However, such a problem can be solved.
　さらに、吸着体３は、例えばシリコンゴムやウレタンゴムからなる連通多孔材であり、その全体は弾性を有ることから、導光板２に吸着体３を当接させた際、導光板２が傷つくことを防止でき、吸着したときの密着性もよく導光板を落下しないよう確実に保持することができる。さらに、導光板２の表面（吸着体３の当接される面）や吸着体３の表面（導光板２に当接される吸着面３ａ）にフッ素をコーティングすると、導光板２の表面や吸着体３の表面に傷がついてしまうことを効果的に防止することができる。 Further, the adsorbent 3 is a continuous porous material made of, for example, silicon rubber or urethane rubber, and the entirety thereof has elasticity. Therefore, when the adsorbent 3 is brought into contact with the light guide plate 2, the light guide plate 2 is damaged. Can be prevented, and the adhesion when adsorbed is good, and the light guide plate can be securely held so as not to fall. Furthermore, when fluorine is coated on the surface of the light guide plate 2 (the surface on which the adsorbent body 3 abuts) or on the surface of the adsorbent body 3 (the adsorbing surface 3 a in contact with the light guide plate 2), the surface of the light guide plate 2 and the adsorption It is possible to effectively prevent the surface of the body 3 from being damaged.
　さらに、本取出装置１の吸着体３は、複数ではなく単独の吸着体３で、単独（一枚）の導光板２を吸着保持しようというものであり、単独の吸着体３には、導光板２を吸着するための複数の連通した孔が形成されている。そして、このような構成を採用することにより、導光板２のサイズよりも吸着体３のサイズが大きく、当該導光板２に対し面接触された吸着体３が、導光板２の外側へはみ出すようなサイズであったとしても、導光板２を吸着することができる。つまり、従来の前記吸盤の個々においては、吸盤と同サイズ若しくは大きいサイズであれば、当該吸盤にて、導光板等の吸着対象物を吸着させることが可能であるが、吸着対象物が、吸盤より小さいサイズである場合には、吸盤と吸着対象物との間に隙間ができてしまい、吸引力を発生させることができないため、吸盤で吸着対象物を吸着保持することができないが、本発明では、図２に示すように、吸着体３のサイズよりも導光板２のサイズが小さく、吸着体３の外側に面接触された導光板２がはみ出すような場合であったとしても、吸着体３として連通多孔材を採用していることで、当該吸着体３で導光板２を吸着保持することができる。 Further, the adsorbing body 3 of the take-out device 1 is not a plurality but a single adsorbing body 3 and is intended to adsorb and hold a single (one piece) light guide plate 2. The single adsorbing body 3 includes a light guide plate. A plurality of communicating holes for adsorbing 2 are formed. By adopting such a configuration, the size of the adsorbent 3 is larger than the size of the light guide plate 2 so that the adsorbent 3 in surface contact with the light guide plate 2 protrudes outside the light guide plate 2. Even if it is a small size, the light guide plate 2 can be adsorbed. That is, in each of the conventional suction cups, if the suction cup is the same size or larger than the suction cup, the suction target object such as a light guide plate can be sucked by the suction cup. In the case of a smaller size, there is a gap between the suction cup and the suction object, and suction force cannot be generated, so the suction object cannot be sucked and held by the suction cup. Then, as shown in FIG. 2, even if the size of the light guide plate 2 is smaller than the size of the adsorbent 3 and the light guide plate 2 in surface contact with the outside of the adsorbent 3 protrudes, the adsorbent By adopting a communicating porous material as 3, the light guide plate 2 can be adsorbed and held by the adsorbent 3.
　以上のように本発明に係わる取出装置１は、光学部品たる導光板２を変形させることなく吸着保持して取出すことができるものであるが、光学部品ではないようなあらゆる部材にも適用できるから、取出装置１や保持装置として、各種技術分野において有効に活用することができる。 As described above, the take-out device 1 according to the present invention can be sucked and held without deforming the light guide plate 2 as an optical component, but can be applied to any member that is not an optical component. The take-out device 1 and the holding device can be effectively used in various technical fields.
