An inspection apparatus of an electric junction box is provided, by which improper mounting of electric parts can be detected. The inspection apparatushas a CCD camera, an image-processing deviceand a control device. The CCD camera picks up images of fusein the electric junction boxas a subject of the inspection. The image-processing devicestores an image consulting data. The image consulting dataincludes a plurality of images of each fusehaving the same item symbol with regard to every item symbol, the fusesbeing used in the electric junction box. The control devicestores normal data indicating the proper item symbol of the fuseto be mounted on a corresponding mount. The image-processing deviceextracts the image most analogous to the image picked up by the CCD camerafrom the images in the image consulting data. The control devicejudges the quality of the item symbol of the fusehaving the most analogous image on the basis of the normal data.

Inspection method of electrical part, inspection apparatus of electric junction box and inspection apparatus of terminal fittings

An inspection method and an inspection system of a terminal metal fitting which can securely judge the good or bad of the fastening condition of an electric wire by a crimping piece of the terminal metal fitting is provided. The inspection system of the terminal metal fitting has an illuminating lamp , a CCD camera , a dark box , and a control unit . The CCD camera is arranged at a position of the light thrown from the illuminating lamp and reflected by crimping pieces of a pressure welding terminal not entering the CCD camera . The dark box covers the illuminating lamp , an object side of the CCD camera , and the pressure welding terminal . The control unit makes a binary processing on an image of a wire connecting portion taken by the CCD camera . The control unit is provided on each of the crimping pieces and judges the good or bad of the crimping condition on the basis of an area in black in an inspection area in the binary image of at least some part of the crimping piece.

A terminal crimping device is composed of an elevating crimper for crimping terminals onto the exposed conductors of cables and an anvil positioned opposite said crimper. The crimper is caused to ascend and descend by means of drive means including a servo motor. The controlling of the terminal crimping operation is done by monitoring the height of the crimper at the time of terminal crimping and the load applied to said drive means and comparing a detected load to the height with the preset reference data to determine whether the terminal crimping performance is good or not. Thus, a reliable determination whether the terminal crimping performance is good or not is performed.

Control method of terminal crimping device

A method of controlling a terminal press attaching device by providing a elevating crimper for crimping terminals onto exposed conductors of the cables, setting an anvil opposite to the crimper, and elevating the drive means including a servo motor. More specifically, the crimp height for press attached terminals is monitored, a detected height and the predetermined set value are compared to control said drive means such that the detected height is made equal to the set value. Thus, the crimp height of the terminal to be attached (or the crimper height) is automatically and easily adjusted.

A method of controlling the terminal crimping device is proposed by providing an elevating crimper for crimping terminals onto exposed conductors of cables, positioning an anvil opposite to said crimper, elevating the drive means including a servo motor. The standard value for determining whether or not the crimper height is out of conformity with the standard value, the administration value for administering the crimper height, and the decision value for determining whether or not the crimping performance is good or not on the basis of the crimper height are recorded such that an alarm is issued when the crimper height is out of conformity with said standard value, said administration value, and said decision value at the time of terminal crimping operation.

A terminal crimping device includes an elevating crimper for crimping terminals onto exposed conductors of cables and an anvil positioned opposite to said elevating crimper so that the ascend/descend of the crimper is carried out by a servo motor. The terminal crimping device further includes a height sensor for outputting a crimp height at the time of crimping said terminals, a data storage unit for storing a pressing time range for determination on whether or not terminal crimping is normal and a crimper height value for determination of said pressing time; and determining unit for time measuring the time during which an output from said height sensor is not larger than the crimper height and determining that crimping is normal if the measured time is within said pressing time range. Thus, the determination on whether or not the terminal crimping is normal can be surely made.

Connector housings having plural kinds of terminals (plated with different materials, e.g.) are mounted at predetermined locations, positioned and secured by a drive means. A sensor probe which receives a light, of a color detection device, is transferred successively to the locations opposite to the terminals. A color sensor senses a level of a specific color component of the light received by the sensor probe. The sensed level is compared with a predetermined reference level and it can be determined based upon whether the sensed level is higher than the reference level, the kind of the terminals in the connector housings.

Identification of connector terminals

In an apparatus that prepares wires necessary for electric wiring by measuring and cutting a length of a wire fed from a wire paying-out device, conveying the cut length of wire in a direction perpendicular to the axial direction of the paid-out wire, stripping wire end portions, and pressing an electrical connector by a connector pressing device, the present invention provides a configuration in which the apparatus can selectively comprise a connector pressing unit composed of a connector pressing device and a pedestal for supporting it on a platform next to the location of the above stripping device, whereby it will facilitate production on many-kinds-and-small-amounts basis as it needs no programming time or adjustment for the replacement of lots.
