Preferably, the center of the optical axis of the camera lens of the second camera of two side pick-up units and product to be detected in the same horizontal line.
Further, when the convergence part between the side and the back side of product to be detected is divided into curved surface, in the application, each side pick-up unit also comprises third camera 53 and the 3rd light source 54.The second support in this technical scheme comprises vertical portion and curve part, and vertical portion is equivalent to the second support in above-described embodiment, installs second camera and secondary light source.The camera lens of two second cameras about product to be detected Central Symmetry and with relative side at a distance of setpoint distance.
Third camera, the 3rd light source are arranged on curve part.Further, third camera, the 3rd light source are installed on mount pad that an electric rotating machine turning axle is arranged jointly.Electric rotating machine is fixed on curve part.Electric rotating machine drives third camera and the 3rd light source with its turning axle synchronous axial system, and make the light beam of the optical axis of third camera and the 3rd light source all the time with product side to be detected with between the back side to be connected curved surface vertical all the time.
Below the principle of work of the product appearance detection system shown in above-described embodiment is described in detail.Fig. 5 shows the process flow diagram that product appearance detection system detects product appearance, as shown in Figure 5, comprises following flow process:
S501: be fixed on locating device by product to be detected, the back side of product to be detected towards the top of bracing frame, and makes the center of product to be detected and the center of locating device on same vertical line.
S502: the position relationship determining back side pick-up unit and the product back side to be detected, and the position relationship of two sides pick-up unit side corresponding thereto.
In this step, back side pick-up unit 4 is comprehensively determined by the thickness of the depth of field of first camera, the height of locating device 3 and product to be detected with the position relationship at the product back side to be detected.Distance range between back side pick-up unit 4 and the product back side to be detected, the picture rich in detail that can obtain the product back side to be detected with first camera is as the criterion.
Distance range between the camera lens of the second camera of two sides pick-up unit and product side to be detected, the picture rich in detail that can obtain the product back side to be detected with second camera is as the criterion.The optical axis of two second camera camera lenses and second camera towards side center in the same horizontal line.In the same horizontal line, two second cameras are about the Central Symmetry of product to be detected simultaneously, can effectively avoid producing during the secondary light source correlation of two sides pick-up unit interfering for the optical axis of two second cameras and the center of product to be detected.
When the side of product to be detected comprises chamfering curved surface, also need to adjust the distance between third camera in side pick-up unit and chamfering curved surface, and the movement locus of setting regulating device, make it consistent with the arching trajectory of chamfering curved surface, thus third camera can be enable to obtain the picture rich in detail of chamfering curved surface all the time.Second camera is for scanning the linking curved surface between side relative in corresponding track and adjacent side.
S503: the motion path of planning back side pick-up unit 4 and two sides pick-up unit, and make two sides pick-up unit in initial position and motion process all about the Central Symmetry of product to be detected.
In the application, back side pick-up unit 4 and two sides pick-up unit simultaneously to towards detection faces detect.The movement locus of back side pick-up unit 4 is straight line, namely back side pick-up unit 4 can at horizontal direction by an edge of product to be detected to another edge motion scan, also can at longitudinal direction by an edge of product to be detected to another edge motion scan.
The movement locus of two sides pick-up unit can have kinds of schemes.Based on avoiding two sides pick-up unit to bump against in testing process, the movement tendency of two sides pick-up unit is identical.The reference position of two sides pick-up unit, about the Central Symmetry of locating device 3, remains the Central Symmetry about product to be detected in operational process.As a side pick-up unit move along clockwise direction time, another side pick-up unit also needs to move along clockwise direction.
Two sides pick-up unit 5 about examined object Central Symmetry, and keeps Central Symmetry in motion process, can will efficiently avoid the mutual interference of second camera in the pick-up unit of two sides like this.Simultaneously, two sides pick-up unit is about examined object Central Symmetry, and the detection time of two sides pick-up unit is consistent to keep Central Symmetry also can ensure in motion process, if the detection path of one of them side pick-up unit is slightly larger than the detection path of another side pick-up unit, then detection time is by the translational speed for two path difference * 2/ side pick-up units.It can thus be appreciated that this path planning is the shortest for the detection time of two sides pick-up unit.
S504: back side pick-up unit and two sides pick-up unit detect simultaneously.
Overleaf pick-up unit 4 and two sides pick-up unit movement locus setting after, under the control of primary controller, back side pick-up unit 4 and two sides pick-up unit simultaneously to towards face to be detected scan, detect.
When the side of product to be detected comprises chamfering curved surface, the side pick-up unit comprising third camera treats the vertical side of testing product and chamfering curved surface carries out scanning, detecting simultaneously.
Back side pick-up unit 4 and two sides pick-up unit detect simultaneously, then the detection time of product appearance detection system, T determined detection time needed for longer that device of used time in back side pick-up unit 4 and side pick-up unit.Can be implemented in T time section like this, the outward appearance detection of product can be carried out complete.With carry out compared with detection, namely simplifying physical construction, also improving detection efficiency to the back side of product and side, four, left, right, front and rear respectively simultaneously.Compared with successively detecting with to five detection faces, its sense cycle significantly shortens.
Further, worktable 1 is provided with the scram button be electrically connected with primary controller, when there is unexpected situation, carrying out equipment suddenly stop by scram button.
From above technical scheme, the surveyed area of product to be detected is divided into three parts by the utility model, and carry out optimum path planning for every part, carry out continuous sweep according to the back side, the path pick-up unit planned and two side pick-up units simultaneously, and the image of acquisition and standard picture are contrasted, and then provide testing result.Therefore, the utility model can significantly improve detection speed and save hardware cost.
Should be understood that, the utility model is not limited to precision architecture described above and illustrated in the accompanying drawings, and can carry out various amendment and change not departing from its scope.Scope of the present utility model is only limited by appended claim.
