Description

本発明は、充電器の性能検査装置に関するものである。   The present invention relates to a performance inspection apparatus for a charger.

近年、デジタルスチルカメラやビデオムービー、携帯電話といった携帯可能な電子機器の市場が急速に伸びている。その中で、携帯型電子機器に電源を供給するための充電型電池パック及び充電器は重要な役割を担っている。民生用の充電器の性能検査は、充電器の中の、部品実装済みの基板の検査を用いて行なうのが通常である。充電器内の基板にテストポイント(以下、TPと記す。)を設け、性能検査装置に設置するテストピンを、TPに刺し、そのTPより得られる出力電圧、電流等で、充電器の性能検査を行なうのが通常である。   In recent years, the market for portable electronic devices such as digital still cameras, video movies, and mobile phones has been growing rapidly. Among them, rechargeable battery packs and chargers for supplying power to portable electronic devices play an important role. In general, the performance of a consumer charger is inspected by inspecting a component-mounted board in the charger. A test point (hereinafter referred to as TP) is provided on the board in the charger, and a test pin installed in the performance inspection device is inserted into the TP, and the performance test of the charger is performed using the output voltage and current obtained from the TP. It is normal to perform.

TPから検査の為の信号を、基板に入力することもある。民生用充電器は、非常に種類が多い。充電器の形状が変わると、それら充電器の中の、基板の形状も変わる。基板が変わると、TPの位置が変わり、その固有の基板に応じた性能検査装置を作成する必要性が生じ、検査器作成に要する費用も莫大となる。一方、充電器の性能検査の内容は、基板が変わっても同じ内容が多く、性能検査に共通の部分を、汎用検査装置として構成し、基板が変わる毎にかわる部分を、ピン治具として作成し、汎用検査装置内に交換可能なピン治具を挿入、接続して性能検査装置とする方が、安価で性能検査が出来る。   A signal for inspection may be input from the TP to the substrate. There are many types of consumer chargers. When the shape of the charger changes, the shape of the board in the charger also changes. When the substrate is changed, the position of the TP is changed, and it becomes necessary to create a performance inspection device corresponding to the specific substrate, and the cost required for producing the inspection device is enormous. On the other hand, the content of the performance inspection of the charger is the same even if the board changes, and the part common to the performance inspection is configured as a general-purpose inspection device, and the part that changes every time the board changes is created as a pin jig However, if a replaceable pin jig is inserted into and connected to the general purpose inspection apparatus to make the performance inspection apparatus, performance inspection can be performed at a lower cost.

しかしながら、充電器の性能検査は、従来のように、充電器の出力に負荷抵抗を接続して、その負荷電流(充電電流)を測定し、製品の良否を検査する単純な方式に比べ、複雑化して来ている。又、検査のトレーサビリティを確保する為、パソコン(以下、PCと記す。)を搭載した汎用検査装置が主流となりつつある。又、検査の高速化も要求される。そのような状況の中、その充電器固有の性能検査の為に作成した交換可能なピン治具を汎用検査装置内に挿入、接続して以後の、検査の自動化が課題となっている。   However, the performance test of the charger is more complicated than the simple method of connecting the load resistance to the output of the charger and measuring the load current (charge current) to check the quality of the product. It is becoming. In order to ensure the traceability of inspection, general-purpose inspection apparatuses equipped with personal computers (hereinafter referred to as PCs) are becoming mainstream. In addition, high-speed inspection is also required. Under such circumstances, automating the inspection after inserting and connecting a replaceable pin jig created for the performance inspection unique to the charger into a general-purpose inspection apparatus has become an issue.

上記、安価で基板検査装置を構成する課題に関して、ピンを固定する分割台部を用いて汎用検査装置上に設置する方法(例えば、特許文献1参照)などが提案されている。   With respect to the above-described problem of configuring a substrate inspection apparatus at a low cost, a method of installing on a general-purpose inspection apparatus using a split base unit for fixing pins (for example, see Patent Document 1) has been proposed.

又、汎用検査装置内に交換可能なピン治具を挿入、接続した充電器性能検査装置の検査の自動化の課題に関しては、図4に示すような構成の充電器性能検査装置を用いた検査方法が実施されている。
特開2005−069954号公報
In addition, regarding the subject of automation of the inspection of the charger performance inspection apparatus in which the replaceable pin jig is inserted and connected in the general-purpose inspection apparatus, an inspection method using the charger performance inspection apparatus having the configuration shown in FIG. Has been implemented.
Japanese Patent Laying-Open No. 2005-069954

しかしながら、図4に示す充電器性能検査装置は、PC内のシーケンスデータ格納部に、検査シーケンスを格納する構成になっており、このシーケンスデータ格納部に、充電器毎の夫々のシーケンスデータが格納されており、汎用検査装置として検査出来る充電器の機種が増えると、そのシーケンスデータの数も莫大となる。検査の項目が同じでも、検査の合否を判定する数値が異なれば、シーケンスデータも変わり、PCに格納されるシーケンスデータの数は莫大なものである。そこで、一つの機種の充電器性能検査をする場合、交換可能なピン治具を交換すると同時に、手動で、その機種のシーケンスデータも選択し、検査を開始しなければならず、検査の自動化とは程遠い実態があった。   However, the charger performance inspection apparatus shown in FIG. 4 is configured to store the inspection sequence in the sequence data storage unit in the PC, and each sequence data for each charger is stored in the sequence data storage unit. As the number of battery charger models that can be inspected as a general-purpose inspection apparatus increases, the number of sequence data also becomes enormous. Even if the items of the inspection are the same, if the numerical values for determining whether the inspection is successful or not are different, the sequence data changes, and the number of sequence data stored in the PC is enormous. Therefore, when testing the performance of a charger of one model, it is necessary to manually select the sequence data of that model at the same time as replacing the replaceable pin jig, and to start the inspection. There was a far-off reality.

特に、生産ライン上、頻繁に機種を変える場合、その交換時間ロスは大きいものがあっ
た。
In particular, when the model is frequently changed on the production line, there is a large exchange time loss.

本発明は、この様な課題を解決するものであり、汎用性のある検査装置に、交換可能なピン治具を挿入、接続してなる充電器性能検査装置で、ピン治具を交換すれば、自動的にその機種のシーケンスデータも選択出来、自動で、かつ安価で構成できる充電器性能検査装置を提供することを目的とする。   The present invention solves such a problem, and when a pin jig is replaced by a charger performance inspection apparatus in which a replaceable pin jig is inserted and connected to a versatile inspection apparatus. It is an object of the present invention to provide a charger performance inspection device that can automatically select sequence data of the model and can be configured automatically and at a low cost.

上記目的を達成するために本発明の充電器性能検査装置は、汎用の充電器性能検査装置内に、交換可能なピン治具を挿入、接続して検査を行なう充電器性能検査装置で、該ピン治具に、充電器を検査する固有情報を保存していることを特徴としている。   In order to achieve the above object, a charger performance inspection device according to the present invention is a charger performance inspection device that performs inspection by inserting and connecting a replaceable pin jig into a general-purpose charger performance inspection device. The pin jig stores unique information for inspecting the charger.

又、充電器を検査する固有情報を、スイッチでコード化して保存することを特徴とする。又、充電器を検査する固有情報を、不揮発性メモリーに保存していることを特徴とする。更に、充電器の機種名及び、又は充電器を検査する固有情報とすることを特徴とする。   In addition, the unique information for inspecting the charger is encoded and stored by a switch. Further, the unique information for inspecting the charger is stored in a nonvolatile memory. Furthermore, the model name of the charger and / or unique information for inspecting the charger are used.

本発明によると、汎用の充電器性能検査装置内に、交換可能なピン治具を挿入、接続するのみで、充電器性能検査装置は、検査すべき特定のシーケンスデータを選び出し、検査を開始できるので、生産ラインに於いて機種切換が発生した場合でも、手動でシーケンスデータを選び出す必要がなく、切換時間ロスの少ない、高速で検査出来る充電器性能検査装置を提供することができる。   According to the present invention, simply by inserting and connecting a replaceable pin jig into a general-purpose charger performance inspection device, the charger performance inspection device can select specific sequence data to be inspected and start the inspection. Therefore, even when model switching occurs in the production line, there is no need to manually select sequence data, and it is possible to provide a charger performance inspection device that can be inspected at high speed with little switching time loss.

Then, the relay and the like in the inspection control circuit 3a are controlled. Since the charger performance inspection device 1a is versatile, the sequence data storage unit 9 in the PC 5 stores the sequence of each charger to be inspected. Conventionally, when the pin jig is changed according to the charger, at the same time, the PC5 keyboard is operated to manually select the charger sequence data from a huge amount of sequence data and start the inspection.

If the model name (model code) of the charger is set in advance as the unique information, the model name code is used for the input / output means 11 in the pin jig 2a and the input / output means 12 in the inspection control circuit 3a. Via the inspection control circuit 3 a and the input / output control device 4. Based on the input information, the PC 5 automatically selects, from the enormous sequence data stored in the sequence data storage unit 9, sequence data specific to the charger to be inspected, and the inspection based on the sequence data. The control information is sent to the inspection control circuit 3a via the input / output control device 4 to the DC power source 7 and the electronic load 8 via the device control device 6 so that the charger-specific inspection can be started. become.
