Description
Technical field
The present invention relates to vision system detection field, is a kind of quick detection terminal of view-based access control model system specifically
Size tool.
Background technology
Connector be electronic engineering technical staff often in contact with a kind of part.Its effect is very simple：In circuit
It is blocked between place or isolated obstructed circuit, the bridge of communication is erected, so that current flowing, makes the work(that circuit realiration is predetermined
Energy.Connector form and structure are Protean, and it is mainly made up of four big basic structural components, is respectively：Terminal, outside
Shell (depending on kind), insulator, annex.
The manufacturing process of connector is punching press, is electroplated, and is molded, assembling.In Shooting Technique section, it is necessary first to will be rolled up after plating
The terminal of disk packaging is molded by mould bending and cuts into single terminal；To ensure the terminal position degree of finished product after being molded,
Height etc. requires that the angle and bending point after terminal bending shaping need strict control.
It is as follows that existing terminal bending cuts process：The good mould of technician's frame simultaneously adjusts bending angle；Send the upper mould of Quality Inspector
Examine；Operator starts to cut terminal after upchecking；Operator send Quality Inspector's inspection after terminal cuts certain amount；Examine logical
Later continue to cut.In the prior art, terminal bending angle and bending point are detected by tool microscope, because instrument shows
The limited amount of micro mirror, and a plant produced connection species it is various, it is necessary to terminal it is also different so that terminal examine
Process stand-by period length is tested, causes terminal cutting and bending to yield poorly, mould efficiency is low；Tool microscope also needs to professional people simultaneously
Member's operation so that operator can not monitor terminal sizes at any time, cause large quantities of terminals cut to be scrapped.
The content of the invention
It is existing for solving it is an object of the invention to provide a kind of quick detection terminal sizes tool of view-based access control model system
There is terminal in technology to examine the stand-by period long, it is necessary to the problem of professional examines.The present invention coordinates by using CCD camera to be schemed
As the size of processor detection terminal, realize terminal and quickly examine and without professional also exercisable effect, simultaneously
By design fixture quick change, realization can measure a variety of terminals, improve the effect of tool utilization rate.
The present invention is achieved through the following technical solutions：
A kind of quick detection terminal sizes tool of view-based access control model system, including base, be arranged on fixture on base and
Camera installing plate, the light source being detachably connected with fixture, the CCD camera being detachably connected with camera installing plate, it is arranged on CCD phases
Camera lens on machine, the image processing apparatus electrically connected with CCD camera；Camera lens is set towards fixture.CCD is charge coupling device
Referred to as, light can be changed into electric charge and electric charge is stored and shifted by it, and can also take out the electric charge of storage becomes voltage
Change, therefore be preferable CCD camera element, CCD camera with small volume, it is in light weight, be unaffected by the magnetic field, with anti-vibration and
Detected target is converted into picture signal, sends special image processing system to by the characteristic of shock, CCD camera, according to
The information such as pixel distribution and brightness, color, is transformed into digitized signal, and image processing system carries out various computings to these signals
To extract clarification of objective, such as position, length, further according to default permissibility and other conditions output result, including size, angle
Degree etc., realizes automatic measurement function.Herein it should be noted that described light source can make positive light source or backlight,
It will be understood by those skilled in the art that the set-up mode of light source is prior art, it is not described here in detail.
Preferably, described image processing apparatus includes control cabinet, industrial computer and PLC in control cabinet, located at control
Display outside case, starter and touch-screen；Industrial computer and PLC electrically connect with CCD camera；Display is electrically connected with industrial computer
Connect；Light source, starter and touch-screen electrically connect with PLC；Described fixture includes the fixture location-plate on base, with
The terminal position fixture that fixture location-plate is located by connecting, terminal position fixture are provided with Norm part close to terminal measured position.PLC
In the main object of the present invention it is that multiple programs are set with touch-screen, to meet that the present invention can measure a variety of terminals, improves this
The utilization rate of invention.The setting of fixture location-plate, it is possible to achieve a variety of terminal clamps are switched fast, and mitigate the labor of operating personnel
Fatigue resistance.What deserves to be explained is, plane and two pitses can be used by being located by connecting herein, neck positioning, the existing way such as pin one side.
Because the processing result image of vision system measurement is number of pixels, in order to converse the actual size of tested part, it is necessary to build
The proportionate relationship of standing statue element and physical size, demarcate the actual physical size that each pixel represents, i.e. pixel equivalent.Due to one
Camera lens number of pixels within the vision is certain, to improve pixel equivalent, must just amplify testee as far as possible, this
The measured zone of reduction testee is just needed, therefore one reference zero is set close to terminal measured position in terminal position fixture
Part, the measuring basis of terminal can be transformed on Norm part, so as to measurement by magnification region, improve accuracy of detection.
Preferably, described fixture is provided with shadow shield, and corresponding to detection zone position on shadow shield is provided with loophole.Due to
Need the region detected to be less than the illuminated area of light source, light source is irradiated to non-detection region, the face of non-detection region can it is reflective extremely
On measured object, measured object contour sharpness is reduced, so as to reduce accuracy of detection.Using shadow shield, light source can be effectively prevented
It is irradiated to non-detection region.
Preferably, described clamp material blackening process or the pitch-dark processing of dye.Because clamp material is mostly metal material,
Metal material is reflective strong, and reflective light is irradiated on measured object, reduces measured object contour sharpness so that accuracy of detection drops
It is low.By clamp material blackening process or the pitch-dark processing of dye, the reflective of clamp material can be effectively reduced, so as to improve detection essence
Degree.
Preferably, described light source is collimated backlight source.Backlight is formed using high brightness, the LED of long-life,
The profile information of measurement or detection object can fully be protruded；Especially, collimated backlight can reduce empty side phenomenon, improve measurement
Precision.
The present invention compared with prior art, has advantages below and beneficial effect：
(1) coordinate image processor to complete the detection of post angle and bending point by CCD camera, realize that terminal sizes are fast
Speed detection, without waiting for, and operated without professional.
(2) quick detection of a variety of terminals is realized by PLC and fixture quick change, improves the utilization rate of the present invention.
(3) by setting shadow shield, the reflective of terminal edge can be effectively reduced, improves the accuracy of detection of the present invention.
(4) by clamp material blackening process or the pitch-dark processing of dye, can effectively prevent that clamp part is reflective, carry
The accuracy of detection of the high present invention.
