Special-purpose Inspections
Connector Inspection A simple setting procedure results in consistent inspection settings The VTV-9000 series systems include all the inspection items necessary for connector production. Because they are special-purpose tools, they enable simple setting where you just check the inspection items. Therefore, there is no variation in inspection setting resulting from the people who perform the setting.

The reasons why the VTV-9000 series systems have become standard tools in the connector industry Covers over 50 items necessary for connector inspection Handle variation in pin array Superior detection performance Handles misalignment inspection
Support/Inquiries
Handle changes in number of pins Correction function convenient for correlation with actual measured value Possible to segment the screen and take images Specialized cameras and lightings for connectors
Super Focusing Camera
Approximately 50 types of inspection items
Inspection item examples Lead pitch measurement (same type) Measures the distance in the pitch direction between detection points for leads of the same type.
Lead pitch measurement (adjoining) Measures the distance in the pitch direction between detection points (Type A - Type B) for adjoining leads.
Lead offset difference measurement Measures the difference in offset between detection points for adjoining leads of the same type.
Supports all kinds of pin arrays With the VTV-9000 series connector lead inspection tool all kinds of pin arrays can be supported just by selecting from the menu. Number of rows: One or two rows (*Three or more rows can also be supported by repeating these). Model (pin shapes) types: One type, two types, one type with one inverted Arrays: Pairs, alternate, zigzag
Superior detection performance Recognition performance: Recognition possible even in complicated backgrounds Precision: Repeat accuracy of 1/4 to 1/2 pixels Easy training: Just enclose with a box High-speed processing: 0.2 to 0.5 msec/search Copying function (rotation, ireverse, etc.) Sharing functions (sharing with other tasks) Origin point editing function
Easy training for position deviation inspections too “Position deviation” is an important inspection for when connectors are produced. If the leads and pins are not in the normal position it leads to serious defects, such as the connectors not being able to connect. With the VTV-9000 series, position deviation inspections can be performed if you simply set the reference point, the distance between the reference point and the first lead, and the ideal pitch.
Handles changes in number of pins Multiple contacts are simple when the shared data function is used! In the case of an object for inspection in which the connector shape is the same and only the number of leads differs, an inspection can be made possible just by obtaining shared data and changing the number of leads and some inspection frameworks. Further, because shared data is managed collectively, in the case where there has been a change in the parameters or model training, all these changes are reflected too.
Numerical correction function No matter how precisely calibration is performed, and even if an optical system which is affected minimally by distortion and the like is prepared, detection values in image processing will not be exactly the same as the actual dimension values. “Numerical correction” is a function that corrects detection values in image processing so that they are the same as the actual dimension values. However, this function cannot be implemented if the repeatability of image processing detection is not high. This function can be included in the VTV-9000 series because we have absolute confidence in its repeatability and a proven track record that backs up our confidence.
Separately taken images can be used to do combined calculations or perform image synthesis Total pitch and coplanarity inspections using the common standard line can be performed
Cameras and lighting specialized for connectors Because they are rectangular they are suited to taking images of connectors.
