Embodiment
A kind of I/O hole shown in Fig. 1 is detected board and is comprised base 1, worktable 2, guide rail 3, leading screw 41, traveling nut 42, L-type bearing 5, CCD device for image 61, camera lens 62, light source 63, pilot hole 7, active light source 8, bearing 9, light source 91, register pin 10, hold down gag 11, protective cover 12, product 13 and datum hole 14.
Board is detected in a kind of I/O hole shown in Fig. 2, Fig. 3 and Fig. 4, mainly comprise base 1, worktable 2, leading screw 41 and relevant linkage structure and pick-up unit, worktable 2 is placed on base 1 by screw mechanism, leading screw 41 and associated linkage mechanism comprise two and are set in parallel in guide rail 3, leading screw 41, motor, the control program on base and form with the traveling nut 42 that worktable is connected, driven by motor leading screw and movable workbench is controlled, adjustment worktable relative position by control program.Two pick-up units are arranged on the same straight line outside two closed slides 3, and be fixed on L-type bearing 5, L-type bearing 5 is movably connected on base 1.This pick-up unit mainly comprises CCD device for image 61, camera lens 62 and light source 63, camera lens 62 is through the pilot hole 7 on L-type bearing 5 side, and connect CCD device for image 61, light source 63 respectively at camera lens 62 two ends, light source 63 plays the effect that increases the brightness of product position to be detected, is convenient to the pixel that CCD device for image obtains better inspection positions product.Camera lens 62 central axis becomes 0 degree of angle during with surface level, obtained the pixel of Product checking position to be detected by CCD device for image, obtain the parameter of product corresponding position through computer disposal.By whether the hole obtaining product corresponding position is got through or blocked up by impurity, a pick-up unit separately established by the L-type bearing 5 of side wherein, camera lens 62 central axis in this pick-up unit and the angle between surface level are between 0 degree to 45 degree, for obtaining best configuration, the angle of this camera lens 62 central axis and surface level is 18 degree.
In order to obtain the product pixel of Product checking position further, below worktable 2 He above product 13, arrange active light source 8, light source 91 respectively, light source 91 is connected on bearing 9.Reliably locate for ensureing that product 13 is placed on worktable 2, worktable 2 four limit is provided with some register pins 10 and hold down gag 11.For improving the dirt exclusion capabilities of pick-up unit, pick-up unit surrounding is provided with protective cover 12.
Concrete action is as follows: motor is by obtaining action command from control program controller, then driven by motor leading screw 41, and leading screw 41 drives worktable 2 to move to predeterminated position, is now placed in product position to be detected on worktable just to camera lens 62 and light source 63.Be placed in the pick-up unit of worktable 2 dual-side, utilize CCD to affect pixel that device 61 obtains position to be detected, machine process obtains correlation parameter as calculated.When camera lens 62 central axis to become the pick-up unit at 0 degree of angle with surface level, as shown in Figure 5, utilize CCD to affect size and position degree, the position degree of its side two aperture 15 to be detected and the profile tolerance of square opening 16 that device 61 obtains datum hole 14, the pick-up unit Detection of content at 0 degree of angle of side is identical with upper in addition.When camera lens 62 central axis to become the pick-up unit at 18 degree of angles with surface level, irradiate into datum hole 13 and two apertures 15 to be detected by light source 63, if Kong Wei gets through or in hole block up by impurity, then light can not penetrate, now the pick-up unit acquisition CCD show hole at 18 degree of angles is plugged, show that this product is defective, need again to do over again.
