Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
As shown in Figure 2,3, 4, retainer is first conveyed into ball-positioning device 4 through material path 12 by loader 2.Wherein, it keeps Frame carries out the screening of front and back sides in loader 2 via positive and reverse screening module 21, guarantees that the retainer for being sent into material strip 12 is all Reverse side is upward.It is equipped with above material path 12 and lacks material and emergency disposal device 3, when sensor 15, which detects, lacks material in material path 12, Stop feeding immediately, and passes through the operation of emergency disposal device recovery device.After retainer leaves material path 12, that is, it is sent into feeding seat 16, bracket 18 is mounted on Mobile base 20, and feeding seat 16 is installed on mount 18, and 18 upper end of bracket is equipped with compression cylinder 13, The output end of compression cylinder 13 is equipped with clamping sleeve 14, and light-duty cylinder 19 is connected through a screw thread with Mobile base 20, under sliding seat 20 Sliding rail 17 is installed.Ball-positioning device 4 is driven to be moved to cylinder gripper from one end close to material path 12 in light-duty cylinder 19 During 52 clip positions, compression cylinder 13 is pushed and is rotated, and the steel ball of retainer is made to reach specified position.
As shown in figure 5, retainer is after ball positions, by cylinder gripper 52 by retainer from the upper of ball locating module Material seat 16 is clamped to the feeding seat 31 of ball clearance Yu scarce pearl detection module.Telescopic cylinder 23,25,27 is fixed on by connector On bracket.The output end of telescopic cylinder 25 is connected with retainer fixed link 28, there is 8 grooves in retainer fixed link 28, corresponds to 8 A precise displacement sensor 29, groove location are located at right above ball.26 phase of output end and lifter plate of telescopic cylinder 23 and 27 Even, 8 precise displacement sensors 29 are fixed on lifter plate 26.Feeding seat 31 is fixed on the base, have on feeding seat 31 8 it is recessed Slot, corresponding 8 mandrils 24, groove location are located at immediately below ball.Telescopic cylinder 30 and 32 is fixed on the base, telescopic cylinder 30 It is connected with 32 output end with lifter plate 33,8 mandrils 24 are fixed on lifter plate 33.Carrying out ball clearance and the detection of scarce pearl When, a pressing force is applied to retainer by retainer fixed link 28 firstF 1, fix retainer.Again by 23 He of telescopic cylinder 27 drive lifter plate 26 to decline, and then 8 precise displacement sensors 29 are driven to decline, and apply a lower pressure to ballF 2, when After displacement sensor 29 can not decline again, i.e., after the numerical stability of displacement sensor 29, current value is read, is denoted asL 1.Then It drives lifter plate 33 to rise by telescopic cylinder 30 and 32, then 8 mandrils 24 is driven to rise, a upper pressure is applied to ballF 3, and F1>F 3>F 2, so that ball is generated a upward displacement, after the numerical stability of displacement sensor 29, read current number Value, is denoted asL 2, by formulaBall clearance size can be calculated, if the ball clearance size being calculated is Zero, then it can determine that herein as scarce pearl.If ball clearance sizeWhen not meeting examination criteria, or judging to have scarce pearl phenomenon, then Retainer is lost into waste product feed opening 56 by cylinder instrument pawl 50;If ball clearance sizeDetection qualification and intact pearl phenomenon, Then retainer is clamped to the feeding seat 37 of reverse side surface defects detection module 7 by cylinder instrument pawl 50.
As shown in fig. 6, feeding seat 37 is fixed on the base, light source 36 is fixed on bracket 34 by connector, is located at upper Expect right above seat 31, CCD camera 35 is fixed on bracket 34 by connector, is located at right above light source 36.Reverse side surface defect Detection module 7 is consistent with the structure of front face surface defects detection module 8.When carrying out retainer surface defects detection, first by CCD camera 35 acquires original image judges whether retainer reverse side surface defect is qualified after algorithm process image.If anti- Face surface defects detection is unqualified, then is lost retainer into waste product feed opening 55 by cylinder gripper 46;If reverse side surface defect Detection is qualified, then is clamped retainer to the feeding seat 41 of front face surface defects detection module 8 by cylinder gripper 46.Such as Fig. 7 Shown, cylinder gripper 46 is mounted on rotating device 47, and when cylinder gripper 46 clamps retainer, surface defect is examined from the negative Module 7 is surveyed toward when the movement of front face surface defects detection module 8, rotating device 47 controls cylinder gripper 46 and rotates 180 °, realizes The overturning of retainer front and back sides then carries out front face surface defects detection.After the completion of retainer front face surface defects detection, by gas Retainer is put into sub-material mouth by cylinder gripper 45, and sub-material mouth controls baffle 54 by motor 53 and rotates, and then controlling retainer is to throw Enter qualified product case 10 or rejected product case 11.
As shown in figure 9, gas circuit design is divided into three parts: main motion module gas circuit, compression module gas circuit and clearance measurement mould Block gas circuit.Main motion module gas circuit is used to provide aerodynamic force for cylinder manipulator 45,46,50,52, realize cylinder manipulator 45, 46,50,52 between modules to measured piece fold up and transfer movement.Compression module gas circuit is used to carry out clearance detection When, pressing force is provided when being fixed to retainer.Clearance measurement module gas circuit is for pushing displacement sensor and mandril Fast lifting and reset.
As shown in Figure 10, periodic calibration is carried out to precise displacement sensor used in utility model device, so as to Ball clearance measurement result is set to trace to the source to national length standard.
The above is only the preferred embodiment of the utility model, not imposes any restrictions to the utility model, all According to any simple modification to the above embodiments of the utility model technical spirit, change and equivalent structural changes, still Belong in the protection scope of technical solutions of the utility model.
