Description

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.

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.

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.

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.

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.
The device unit includes a pedestal, a rotating member installed on the pedestal, and a rotating disk rotatably installed on the rotating member, and a supply area, an inspection area, and a sorting area are provided on the rotating disk. Areas are arranged in order,
The control unit is arranged outside the device unit and is electrically connected to the rotating member, and the control unit can control the rotating member to rotate the rotating disk. ,
The plurality of image pickup units are arranged adjacent to the inspection area and around the device unit so as to surround the outer periphery of the turntable, and are electrically connected to the control unit, and each image pickup unit is electrically connected to the control unit. A mounting seat attached to the pedestal, a drive member attached to the mounting seat and electrically connected to the control unit, and a zoom lens attached to the mounting seat and electrically connected to the control unit. The zoom lens transfers the captured image data to the control unit, and is driven by the driving member to change the focal length.
The sorting unit is adjacent to the sorting area, is arranged around the device unit so as to surround the outer periphery of the turntable, and is electrically connected to the control unit.

According to the inspection device of the present invention, when an inspection object is passed through a plurality of imaging units by using a rotating disk, an image of the inspection object captured by the plurality of imaging units is transmitted to the control unit and controlled. The unit analyzes images of a plurality of inspection objects provided by a plurality of imaging units, whereby the inspection accuracy for the inspection target can be improved, and the control unit can improve the inspection accuracy of the inspection target. 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.
