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. 8
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 10, 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.

3. plain thrust bearing retainer surface scratch, ball clearance and scarce pearl situation detection method, using described in claim 1
Device, it is characterised in that: keep a large amount of plain thrust bearing retainer by charging barrel and positive and reverse screening module first
Reverse side is upward and uniform sequential by material strip feeding material receiving device.By lack material with emergency disposal module detection material strip in whether
Material is lacked, if lacking material, stops feeding and detection immediately, and pass through the operation of manual intervention recovery device.Retainer passes through material
Band initially enters ball locating module, to one pressure of retainer and is rotated by compression cylinder, and steel ball is made to reach specified position.
It drives sliding seat to reach specified position by light-duty cylinder, is clamped by cylinder gripper one, under the phorogenesis of displacement cylinder,
Retainer is clamped to ball clearance and scarce pearl detection module first.Same holding is measured simultaneously by eight precise displacement sensors
The displacement of eight ball high-low limit positions on frame, the i.e. size of ball clearance；If the ball clearance value measured is zero,
Determine herein for scarce pearl.It after detection, is clamped by cylinder gripper two, if ball clearance passes through with the detection of scarce pearl, is being moved
Under the phorogenesis of position cylinder, by retainer clamping to reverse side surface defects detection module.If ball clearance and scarce pearl detect not
Pass through, then drives cylinder gripper two to be moved to the inspection of reverse side surface defect from ball clearance and scarce pearl detection module by displacement cylinder
When surveying module, finger is unclamped by independent gas circuit control cylinder gripper two, retainer investment is located at ball clearance and scarce pearl is examined
Survey the waste product blanking groove between module and reverse side surface defects detection module.After retainer reaches reverse side defects detection module, by
Camera acquires original image, is handled by computer image, to judge retainer reverse side with the presence or absence of surface defect.Inspection
After survey, clamped by cylinder gripper three, if reverse side surface defects detection passes through, under the phorogenesis of displacement cylinder,
By retainer clamping to front face surface defects detection module.In translation motion, by the rotating mechanism being fixed on lifter plate, by gas
Cylinder gripper three rotates 180 °, makes retainer turn-over.If reverse side surface defects detection does not pass through, cylinder is driven by displacement cylinder
Gripper three is mechanical by independent gas circuit control cylinder when surface defects detection module is to front reverse side defects detection module from the negative
Pawl unclamps finger, and retainer investment is useless between reverse side surface defects detection module and front face surface defects detection module
Product blanking groove.After retainer reaches positive defects detection module, original image is acquired by camera, image is carried out by computer
Processing, to judge retainer front with the presence or absence of surface defect.It after detection, is clamped by cylinder gripper four, in displacement gas
Under the drive of cylinder, retainer is put into sub-material mouth, judges that investment is closed according to the signal of front face surface defects detection module output
Lattice product case or rejected product case are rotated by the baffle of motor control sub-material mouth, realize the sorting of retainer.Meanwhile device can
It realizes line tact operation, greatly improves detection efficiency, realize quality testing continuous to retainer, efficient and sorting.
What 4. plain thrust bearing retainer surface scratch according to claim 3, ball clearance and scarce pearl were detected
Method, it is characterised in that: periodic calibration is carried out to precise displacement sensor used in apparatus of the present invention, so as to swim ball
Gap measurement result is traced to the source to national length standard.
