Description

本発明は、液晶ディスプレイの検査冶具に関する。   The present invention relates to an inspection jig for a liquid crystal display.

一般に、携帯電話等に組み込まれる液晶ガラス基板の通電検査等の品質検査は、信頼性の高い部品提供のために、現状においては全数検査が実施されている。
具体的には、板面にプリント配線された線状パターンの電極端子群に、通電検査用の制御機器又は基板に接続された検査用電極ピンを人的操作によって接触通電状態にすることにより、液晶ディスプレイを試験作動して品質の良否を行うことが実施されていたが、各電極端子の端子幅、隣り合う電極端子の間隔、電極端子の配列ピッチ等の各寸法が小さく、接触操作に熟練を必要とすることによって作業難度が高いため、近時においては、液晶ガラス基板の電極端子群に対応する電極端子群を備えたフレキシブル基板からなる検査用制御基板を、予めに、検査する全ての液晶ガラス基板に半田付けによって接合しておき、この検査用制御基板に通電して液晶ガラス基板の通電検査を実施して、良品か不良品かの選別を行うことが実施され作業性の改善が図られている(例えば、特許文献1参照。)。
In general, in order to provide highly reliable parts, quality inspection such as energization inspection of a liquid crystal glass substrate incorporated in a mobile phone or the like is currently in full inspection.
Specifically, the electrode terminal group of the linear pattern printed and wired on the plate surface is brought into a contact energized state by a human operation of a control device for energization inspection or an inspection electrode pin connected to the substrate, Tests were conducted to test the quality of liquid crystal displays, but the dimensions such as the terminal width of each electrode terminal, the distance between adjacent electrode terminals, and the arrangement pitch of electrode terminals were small, and they were skilled in contact operations. In recent years, the inspection control board made of a flexible substrate having an electrode terminal group corresponding to the electrode terminal group of the liquid crystal glass substrate is pre-inspected. Bonding to the liquid crystal glass substrate by soldering, energizing the control board for inspection and conducting an energization inspection of the liquid crystal glass substrate to select whether it is a good product or a defective product Improvements are achieved (e.g., see Patent Document 1.).

特開2002−324601公報(第2頁、図2)JP 2002-324601 A (second page, FIG. 2)

しかしながら、このような品質検査において、液晶ガラス基板、検査用制御基板、液晶ガラス基板に対する検査用制御基板の半田付け箇所の何れか一つに不具合があると、例え、検査対象主体である液晶ガラス基板が良品であったとしても不良品扱いになり、検査コストの観点から、その対象となった液晶ガラス基板は検査用制御基板が接合されたままの状態で廃棄処理するのが合理的であるという判断から実施されているが、反面、歩留まりの向上を妨げる一要因になっている。
また、良品である場合、検査の後工程として、半田付けを解いて液晶ガラス基板から検査用制御基板を分離して単独の液晶ガラス基板部品に戻さなければならず、手間がかかる問題がある。
さらに、液晶ガラス基板の電極端子群は、例えば、端子幅が0.14mm、隣り合う端子間は0.18mm、配列ピッチが0.32mmと言うように、線間間隔寸法が小さく、液晶ガラス基板に対する半田付け不良を生じたりすることがあるため、接合に慎重を要して作業性が悪い問題がある。
そのため、液晶ガラス基板に検査用制御基板を半田付けされた検査対象物を準備する検査段取り工程、検査対象物を実検査する検査工程、液晶ガラス基板から検査用制御基板を分離する検査後工程、及び、これらの工程に付随する製作、運搬、在庫等の各種作業と言うように、検査に係わる工程や作業が多いとともに、液晶ガラス基板に半田付けされる検査用制御基板を検査用部品として常備品化しておく必要があるなど、一般の部品検査に比べて、作業性、コスト性、量産対応性等が悪いと言った問題がある。
However, in such quality inspection, if any one of the liquid crystal glass substrate, the inspection control substrate, and the soldered portion of the inspection control substrate with respect to the liquid crystal glass substrate is defective, for example, the liquid crystal glass that is the subject of inspection Even if the substrate is non-defective, it will be treated as a defective product, and from the viewpoint of inspection costs, it is reasonable to dispose of the target liquid crystal glass substrate while the inspection control substrate is still bonded. However, it is a factor that hinders yield improvement.
Further, in the case of a non-defective product, as a post-test process, it is necessary to remove the soldering and separate the control substrate for inspection from the liquid crystal glass substrate and return it to a single liquid crystal glass substrate component.
Further, the electrode terminal group of the liquid crystal glass substrate has a small distance between lines, for example, a terminal width of 0.14 mm, a distance between adjacent terminals of 0.18 mm, and an arrangement pitch of 0.32 mm. In some cases, soldering failure may occur, so that it is necessary to be careful in joining and workability is poor.
Therefore, an inspection setup process for preparing an inspection object in which the inspection control board is soldered to the liquid crystal glass substrate, an inspection process for actually inspecting the inspection object, a post-inspection process for separating the inspection control board from the liquid crystal glass substrate, In addition, there are many processes and operations related to inspection, such as production, transportation, inventory, etc. associated with these processes, and an inspection control board soldered to the liquid crystal glass substrate is always provided as an inspection part. There is a problem that workability, cost efficiency, mass production compatibility, etc. are poor compared to general parts inspection, such as the need for commercialization.

本発明は、上述の実状に鑑みて為されたものであって、その主たる課題は、歩留まりの向上を図るとともに、作業性、コスト性、量産対応性に優れた液晶ガラス基板の検査冶具を提供する点にある。   The present invention has been made in view of the above-described circumstances, and its main problem is to provide an inspection jig for a liquid crystal glass substrate that is excellent in workability, cost efficiency, and mass production compatibility while improving yield. There is in point to do.

本発明の請求項1による液晶ガラス基板の検査冶具の特徴構成は、着脱自在に位置保持された液晶ガラス基板の板面に形成された線配列パターンの電極端子群に対応して、同線配列パターンの中継端子群が形成された中継コネクタを備えるとともに、液晶ガラス基板の電極端子群に対して中継コネクタの中継端子群が接触する接続状態と、液晶ガラス基板の電極端子に対して中継コネクタの中継端子群が離隔する非接続状態とに切換え可能にする切換え手段を備える点にある。   According to a first aspect of the present invention, there is provided a characteristic configuration of the inspection jig for the liquid crystal glass substrate corresponding to the electrode terminal group of the line arrangement pattern formed on the plate surface of the liquid crystal glass substrate which is detachably held. A relay connector having a pattern of relay terminals is formed, and a connection state in which the relay terminal group of the relay connector is in contact with the electrode terminal group of the liquid crystal glass substrate; It is in the point provided with the switching means which can be switched to the non-connection state which a relay terminal group separates.

上記特徴構成によれば、切換え手段を介して、液晶ガラス基板の被検査側電極端子群に中継コネクタの中継端子群を一括に接続状態にして、例えば、中継コネクタ経由で液晶ガラス基板を通電して、液晶ガラス基板の通電検査を実施することができ、この状態から切換え手段を介して両端子を離隔した非接続状態にして、検査を終えた液晶ガラス基板の位置保持を解いて新たな別の液晶ガラス基板に取替えることができ、この状態から接続状態にして、新たに位置保持された液晶ガラス基板の通電検査を実施することができると言うような検査作業を連続して実施することができる。
しかも、液晶ガラス基板の検査側電極端子群が、電極端子幅、隣り合う電極端子間の間隔、配列ピッチ等の寸法が微細化なものの場合においても、液晶ガラス基板の電極端子群と中継端子群が同配列パターンで対応しており、両者を確実に接続状態にすることができ、正確に液晶ガラス基板の検査を実施することができる。
そのため、従来のように液晶ガラス基板の電極端子に電極ピンを手作業で接触操作していた、熟練を要する検査や、半田付けで接合され液晶ガラス基板に検査だけに使用される検査用制御基板を用いていた、コストが高く量産対応性が悪く、歩留まり向上を望めない検査に比して、検査の作業性が良いとともに、信頼性の高い検査を実施することができ、コスト性、量産対応性の向上、及び、歩留まりの向上を図ることができる。
ここで、線配列パターンとは、多数の線を一方向に沿って、等間隔、又は、不等間隔の配列を意味する。
According to the above characteristic configuration, the relay terminal group of the relay connector is collectively connected to the inspection-side electrode terminal group of the liquid crystal glass substrate via the switching means, and for example, the liquid crystal glass substrate is energized via the relay connector. The liquid crystal glass substrate can be inspected for energization. From this state, the terminals are separated from each other through the switching means, and the position of the liquid crystal glass substrate that has been inspected is released and a new one is released. It can be replaced with a liquid crystal glass substrate, and from this state, it is possible to continuously carry out inspection work such as conducting a current inspection of a newly held liquid crystal glass substrate from a connected state. it can.
In addition, even when the inspection-side electrode terminal group of the liquid crystal glass substrate is such that the electrode terminal width, the distance between adjacent electrode terminals, the arrangement pitch, etc. are miniaturized, the electrode terminal group and the relay terminal group of the liquid crystal glass substrate Correspond to each other in the same arrangement pattern, and the two can be reliably connected to each other, and the liquid crystal glass substrate can be inspected accurately.
Therefore, as in the past, the electrode pins were manually contacted with the electrode terminals of the liquid crystal glass substrate, and the inspection control board used only for the inspection that requires skill or the soldered and joined to the liquid crystal glass substrate Compared to inspections that use high-cost, low-productivity and low-yield improvement, yields can be performed with high reliability and high-reliability inspections. Improvement in yield and yield can be achieved.
Here, the line arrangement pattern means an arrangement with a large number of lines arranged at equal intervals or unequal intervals along one direction.

本発明の請求項2による液晶ガラス基板の検査冶具の特徴構成は、着脱自在に位置保持された液晶ガラス基板の板面に形成された線配列パターンの電極端子群に対応する検査対象側中継端子群が一端側に形成され、位置保持された検査用制御基板の板面に形成された線配列パターンの電極端子群に対応する計測側中継端子群が他端側に形成された中継配線群が配線された中継コネクタを備えるとともに、検査用制御基板の電極端子群と中継コネクタの計測側中継端子群を着脱自在に接続する接続手段、及び、中継コネクタの検査対象側中継端子群を着脱自在に保持し、且つ、検査用制御基板の電極端子群と中継コネクタの検査対象側中継端子群を接続状態と非接続状態とに切換え可能にする切換え手段を備える点にある。   The characteristic configuration of the inspection jig for the liquid crystal glass substrate according to claim 2 of the present invention is the inspection object side relay terminal corresponding to the electrode terminal group of the line array pattern formed on the plate surface of the liquid crystal glass substrate held in a detachable manner. A relay wiring group in which a measurement-side relay terminal group corresponding to the electrode terminal group of the line arrangement pattern formed on the plate surface of the inspection control board, which is formed on one end side and held in position, is formed on the other end side. In addition to the wired relay connector, the connection means for detachably connecting the electrode terminal group of the inspection control board and the measurement-side relay terminal group of the relay connector, and the inspection target side relay terminal group of the relay connector are detachable There is a switching means for holding and switching the electrode terminal group of the inspection control board and the inspection object side relay terminal group of the relay connector between a connected state and a non-connected state.

上記特徴構成によれば、中継コネクタの計測側中継端子群と検査用制御基板の電極端子群が接続された接続側に対して、切換え手段を介して、液晶ガラス基板の電極端子群と中継コネクタの検査対象側中継端子群を一括に接続状態にして、検査側制御基板と液晶ガラス基板とを通電接続状態にすることによって、液晶ガラス基板を検査することができ、切換え手段を介して、液晶ガラス基板の電極端子群と中継コネクタの検査対象側中継端子群を非接続状態にし、続いて、検査を終えた液晶ガラス基板の位置保持を解いて新たな別の液晶ガラス基板を位置保持する状態に取替え、この状態から切換え手段を介して接続状態にして、新たに位置保持された液晶ガラス基板を通電検査することができると言うような検査作業を連続して実施することができる。
しかも、検査用制御基板に対する中継コネクタとの接続を解くとともに、切換え手段に対する中継コネクタの保持を解いて、新たな中継コネクタを検査用制御基板に接続するとともに、切換え手段に保持することによって、中継コネクタの交換を実施することができる。
そのため、従来のように液晶ガラス基板の電極端子に電極ピンを手作業で接触操作していた、熟練を要する検査や、専用の検査用制御基板を半田付けによって接合して検査用の液晶ガラス基板を作らなければならず、検査コストが高く、量産対応性も悪く、歩留まりの向上を望めない検査に比して、連続して液晶ガラス基板を検査することができるとともに、中継コネクタの交換も可能であるので、検査の効率の良い作業が可能であるとともに、信頼性の高い検査を実施することができ、コスト、量産対応性の向上、及び、歩留まりの向上を図ることができる。
According to the above characteristic configuration, the electrode terminal group of the liquid crystal glass substrate and the relay connector are connected via the switching means to the connection side where the measurement side relay terminal group of the relay connector and the electrode terminal group of the inspection control board are connected. The liquid crystal glass substrate can be inspected by bringing the inspection side relay terminal group into a connected state at once, and bringing the inspection side control board and the liquid crystal glass substrate into an energized connection state. A state in which the electrode terminal group of the glass substrate and the relay terminal group on the inspection connector side of the relay connector are disconnected, and then the position of the liquid crystal glass substrate that has been inspected is released and another liquid crystal glass substrate is held in position. In this state, the liquid crystal glass substrate newly held in position can be energized and inspected continuously by switching to the connected state via the switching means. Can.
In addition, the relay connector is disconnected from the inspection control board, and the relay connector is released from the switching means, and the new relay connector is connected to the inspection control board and held in the switching means. Connector replacement can be performed.
Therefore, as in the past, the electrode pins were manually contacted with the electrode terminals of the liquid crystal glass substrate, and inspections requiring skill and a liquid crystal glass substrate for inspection by joining a dedicated inspection control board by soldering Compared to inspections that require high cost, low inspection, and low yields, LCD glass substrates can be inspected continuously, and relay connectors can be replaced. Therefore, it is possible to perform work with high efficiency of inspection, perform highly reliable inspection, and improve cost, mass production compatibility, and yield.

本発明の請求項3による液晶ガラス基板の検査冶具の特徴構成は、前記中継コネクタが、一面に中継配線が配線されている可撓性を有するシート状のベース体から形成されている点にある。   The characteristic configuration of the inspection jig for the liquid crystal glass substrate according to claim 3 of the present invention resides in that the relay connector is formed of a flexible sheet-like base body on which one surface of the relay wiring is wired. .

上記特徴構成によれば、液晶ガラス基板の電極端子群に対して中継コネクタの中継端子群が対面する接続状態を実施することができるので、対応する接点同士の位置合わせを行なうことによって接続状態にすることができるとともに、中継コネクタが可撓性を有するので、切換え手段による対面による接続動作と非接続動作の反復使用に伴う曲げや歪を吸収して安定性のある使用が可能となる。   According to the above characteristic configuration, since the connection state where the relay terminal group of the relay connector faces the electrode terminal group of the liquid crystal glass substrate can be carried out, the connection state is achieved by aligning the corresponding contacts. In addition, since the relay connector is flexible, it can be used with stability by absorbing bending and distortion associated with repeated use of the connecting operation and the non-connecting operation by the switching means.

従って、液晶ガラス基板の電極端子群における、電極端子幅、隣り合う電極端子間の間隔、配列ピッチ等の寸法が小さい場合においても、対応する接点同士を正確に接続状態にすることができ検査接続の信頼性の向上を図れるとともに、一つの中継コネクタで多数の液晶ガラス基板の検査を安定的に実施することができるので、検査信頼性の高い検査冶具を形成することができる。   Therefore, even when the dimensions of the electrode terminal group of the liquid crystal glass substrate, such as the electrode terminal width, the interval between adjacent electrode terminals, and the arrangement pitch, are small, the corresponding contacts can be accurately connected to each other for inspection connection. In addition, since a plurality of liquid crystal glass substrates can be stably inspected with one relay connector, an inspection jig with high inspection reliability can be formed.

本発明の請求項4による液晶ガラス基板の検査冶具の特徴構成は、前記中継コネクタの検査対象側中間端子群が、弾性変形可能なシート部分に形成されている点にある。   The characteristic configuration of the inspection jig for the liquid crystal glass substrate according to claim 4 of the present invention resides in that the inspection target side intermediate terminal group of the relay connector is formed on a sheet portion that can be elastically deformed.

上記特徴構成によれば、液晶ガラス基板の電極端子群に対して中継コネクタの中継端子群が弾性変形を伴って接触する状態となり、電極端子群に対して柔軟な接触が可能となるので、電極端子群を傷つけるようなことがない。   According to the above characteristic configuration, the relay terminal group of the relay connector comes into contact with the electrode terminal group of the liquid crystal glass substrate with elastic deformation, and flexible contact with the electrode terminal group becomes possible. No damage to the terminals.

従って、液晶ガラス基板の電極端子群の欠損不良等を生じることがなく、液晶ガラス基板の品質が保たれるので、多数の液晶ガラス基板の検査を安定的に実施することができる。   Therefore, the defect of the electrode terminal group of the liquid crystal glass substrate does not occur, and the quality of the liquid crystal glass substrate is maintained, so that a large number of liquid crystal glass substrates can be inspected stably.

本発明の請求項5による液晶ガラス基板の検査冶具の特徴構成は、前記中継コネクタの検査対象側中間端子群が、弾性変形素材の台座を介して支持されている点にある。   The characteristic configuration of the inspection jig for the liquid crystal glass substrate according to claim 5 of the present invention is that the inspection target side intermediate terminal group of the relay connector is supported via a base of an elastically deformable material.

上記特徴構成によれば、中継コネクタの中継端子に対して、液晶ガラス基板の電極端子が接触した際の押圧力が、台座の弾性変形によって吸収されて、液晶ガラス基板に鋭角的な押圧力が加わることがないので、液晶ガラス基板の破損を懸念することなく検査することができる。   According to the above characteristic configuration, the pressing force when the electrode terminal of the liquid crystal glass substrate contacts the relay terminal of the relay connector is absorbed by the elastic deformation of the pedestal, and the acute pressing force is applied to the liquid crystal glass substrate. Since it does not add, it can test | inspect without worrying about the failure | damage of a liquid crystal glass substrate.

従って、安定性のある連続検査を実施することができる。   Therefore, a stable continuous inspection can be performed.

本発明の請求項6による液晶ガラス基板の検査冶具の特徴構成は、前記液晶ガラス基板と前記中継コネクタ基板に照準マークが標記され、位置保持された液晶ガラス基板に対面し,且つ、中継コネクタの検査対象側中継端子群を保持する台座側に覗き孔が形成され、覗き孔を通して液晶ガラス基板と中継コネクタの照準マークが一致する照準状態で、液晶ガラス基板の電極端子群と中継コネクタの検査対象側中継端子群との接続関係が対応する位置決め手段を備える点にある。   According to a sixth aspect of the present invention, there is provided a liquid crystal glass substrate inspection jig characterized in that an aiming mark is marked on the liquid crystal glass substrate and the relay connector substrate, facing the liquid crystal glass substrate held in position, and the relay connector Inspection target side of liquid crystal glass substrate electrode terminal group and relay connector in a sighting state where a viewing hole is formed on the pedestal side holding the relay terminal group on the inspection target side and the sighting mark of the liquid crystal glass substrate and the relay connector is aligned through the viewing hole The connection relationship with the side relay terminal group is provided with a corresponding positioning means.

上記特徴構成によれば、位置決め孔から位置保持された液晶ガラス基板の照準マークが,中継コネクタの照準マークと重合状態に照準されておれば、液晶ガラス基板が正確に位置保持されており、重合していなければ液晶ガラス基板が位置ずれして保持されているか、或いは、台座が位置ずれしているかの確認をとることができる。   According to the above characteristic configuration, if the aiming mark of the liquid crystal glass substrate held in position from the positioning hole is aimed at the overlapping state with the aiming mark of the relay connector, the position of the liquid crystal glass substrate is accurately held. If not, it can be confirmed whether the liquid crystal glass substrate is held displaced or whether the pedestal is displaced.

そのため、検査される液晶ガラス基板毎に確認作業を実施することによって、液晶ガラス基板の電極端子群と中継コネクタの中継端子群とを正確に接続することができ、信頼性の高い検査を実施することができる。   Therefore, by carrying out the confirmation work for each liquid crystal glass substrate to be inspected, the electrode terminal group of the liquid crystal glass substrate and the relay terminal group of the relay connector can be accurately connected, and a highly reliable inspection is performed. be able to.
