Description

本発明は、検品装置に関し、特に、装置の調整作業を行うための所要のスペースを節約でき、かつ検品精度を向上できる検品装置に関するものである。 The present invention relates to an inspection device, and more particularly to an inspection device capable of saving a space required for adjusting the device and improving inspection accuracy.

画像検品技術は現在の検品技術としてよく使われる技術の一つであり、この方法については、搬送手段を利用して、検査対象物を、照明設備及び撮像設備に通過させ、その間に、照明光を照射することにより、当該検査対象物が該撮像設備の感光性チップ（例えば、電荷結合デバイス、ＣｈａｒｇｅＣｏｕｐｌｅｄＤｖｉｃｅ、略称ＣＣＤ)上に成像され、該感光性チップを介して、成像された画像をディジタル情報に変換して、コンピューターに送信し、次に、該コンピューターは、このディジタル情報を分析し、参照データと比較して、当該検査対象物が良品かどうかを判断し、その判断結果を、該コンピューターのモニターに表示し、同時に搬送手段の排出機構に送信し、すると、該排出機構は、検査対象物を、良品収集箱または不良品収集箱へ排出する。このような画像検品技術は、検査速度が速く、検品精度も高いので、現在の検品技術において欠かせない技術の一つである。 Image inspection technology is one of the technologies often used as the current inspection technology. In this method, an inspection object is passed through a lighting facility and an imaging facility by using a transport means, and in the meantime, illumination light is used. By irradiating the image, the inspection object is imaged on a photosensitive chip (for example, charge coupling device, Charge Coupled Device, abbreviated as CCD) of the imaging facility, and the image formed through the photosensitive chip is displayed. It is converted into digital information and transmitted to a computer, and then the computer analyzes this digital information and compares it with the reference data to determine whether the inspection object is a non-defective product, and the result of the determination is determined. It is displayed on the monitor of the computer and simultaneously transmitted to the discharging mechanism of the transport means, and the discharging mechanism discharges the inspection object to the good product collection box or the defective product collection box. Such an image inspection technique is one of the indispensable techniques in the current inspection technique because the inspection speed is high and the inspection accuracy is high.

しかしながら、検査対象物は、様々な種類があるため、見た目の寸法や形状が異なることから、既存の画像検品技術に利用される撮像設備は、撮像工程を施す時に、検査対象物に対する焦点距離がずれたり、撮像範囲が小さかったりする場合があれば、操作員が手作業で撮像設備の設置位置を変更したり、撮像設備と検査対象物との間の距離を調整したりする。ところが、例えば、ただ一台の撮像設備を利用する場合、この一台の撮像設備で捉えた画像を検品の判断基準としては不十分であり、また、手作業で撮像設備の位置を調整する場合、その撮像設備の設置位置は、毎回若干異なるため、検品精度に影響が出るので、誤判断をする虞があった。さらにまた、撮像設備の撮像可能な範囲は、当該撮像設備と検査対象物との間における移動可能な距離によって限られており、つまり、撮像設備におけるとある検査対象物に対する合焦距離が、該撮像設備の移動可能な距離より大きい場合、該撮像設備は、設置場所の制約を受け、画像を鮮明に撮ることができない問題を有する。 However, since there are various types of inspection objects, the apparent dimensions and shapes are different. Therefore, the imaging equipment used in the existing image inspection technology has a focal length with respect to the inspection object when the imaging process is performed. If there is a deviation or the imaging range is small, the operator manually changes the installation position of the imaging equipment or adjusts the distance between the imaging equipment and the inspection object. However, for example, when using only one imaging equipment, the image captured by this one imaging equipment is not sufficient as a criterion for inspection, and when the position of the imaging equipment is manually adjusted. Since the installation position of the imaging equipment is slightly different each time, the inspection accuracy is affected, and there is a risk of making an erroneous judgment. Furthermore, the range in which the imaging equipment can be imaged is limited by the movable distance between the imaging equipment and the inspection object, that is, the focusing distance with respect to a certain inspection object in the imaging equipment is the said. If it is larger than the movable distance of the imaging equipment, the imaging equipment has a problem that the image cannot be clearly taken due to the limitation of the installation place.

本発明は、前記の従来技術の欠点に鑑みてなされたものであり、ただ一台の撮像設備で捉えた画像を検品の判断基準としては不十分である問題、手作業で撮像設備の位置を調整することによって位置ずれが生じて検出精度に影響を与える問題、及び撮像設備と検査対象物との間における移動可能な距離が、設置場所の制約を受ける問題を解決する検品装置を提供することを目的としている。 The present invention has been made in view of the above-mentioned drawbacks of the prior art, and the problem that the image captured by only one image pickup device is insufficient as a criterion for inspection, the position of the image pickup device is manually determined. To provide an inspection device that solves the problem that misalignment occurs due to adjustment and affects the detection accuracy, and the problem that the movable distance between the imaging equipment and the inspection object is restricted by the installation location. It is an object.

前記選別ユニットは、前記仕分けエリアに隣接し、前記回転盤の外周を囲繞するように前記デバイスユニットの周囲に配置される共に、前記制御ユニットと電気的に連結されることを特徴とする。 In order to achieve the object of the above invention, the present invention is an inspection device, which includes a device unit, a control unit, a plurality of imaging units, and a sorting unit.

Whether or not it is determined, and based on the determination result, the sorting unit is controlled to perform highly accurate sorting work, and the control unit controls each driving member of each imaging unit. The focal lengths of the imaging units can be matched, whereby the adjustment accuracy via the control unit is significantly improved over the manual adjustment accuracy, and the plurality of imaging units generated by the plurality of imaging units. Since the image can be taken uniformly, the risk of erroneous judgment in image inspection can be eliminated, and the focal length of the zoom lens can be adjusted via the drive member. Since it is not necessary to adjust the installation position of the lens, there are no restrictions on the location for focus adjustment work or equipment installation.
