Below in conjunction with accompanying drawing and preferred embodiment, the embodiment according to cylinder of the present utility model (pipe) workpiece side (post) face open defect and flaw automatic tester, structure, feature and effect are described in detail.
Note, " cylinder " in the instructions of the application and claims comprises solid cylinder and hollow pipe, is also included within cylinder other structure with at least one cavity; Side surface of workpiece and workpiece cylinder represent the same meaning; " defect " and " flaw " has broadest sense and can replace each other.
As shown in Figure 1, Figure 2, Figure 3 shows, cylinder of the present utility model (pipe) workpiece side (post) face open defect automatic tester is formed primarily of test platform 2 and auxiliary element.
On detector, auxiliary element can comprise straight line feeder 4, straight line feeder controller 3, straight line feeder base 5, lower margin fixed mount 6, damping hoof pin 7, pilot lamp 1, display 9, indicator bracket 8, defective workpiece disposable box 10, keyboard 11, mouse 12, industrial computer 15, panel box 13, test platform base 14.
The camera frame 16 be fixed on test platform base 14 can be provided with in test platform 2, camera and camera lens 17, light source 18, rotating axis component 19, workpiece feeding is to level sensor 20, carrying roller alignment sensor 21, blow gun 22 assisted by material loading, belt member 23, defective workpiece blow gun 24, cylinder part 25, alignment sensor 26 rejected by workpiece, cylinder 27, workpiece blanking is to level sensor 28, workpiece test position fix sensor 29, blow gun 30 is assisted in blanking, carrying roller parts 31, treat material loading workpiece 32, cylinder backgauge head 33, cylinder reaches level sensor 34, cylinders retract is to level sensor 35, belt 36, carrying roller end regulating part 37, carrying roller 38, carrying roller rotates induction pieces 39, workpiece for measurement 40, blanking puts in place workpiece 41.
As shown in Figure 3, measured workpiece is travelled forward by straight line feeder 4, in arrival Fig. 3 when the position of material loading workpiece 32, workpiece feeding receives signal to level sensor 20, carrying roller 38 rotates, make to treat that material loading workpiece 32 moves to test station by carrying roller end regulating part 37, and assist the cylinder backgauge head 33 in blow gun 22, cylinder part 25 to treat by material loading material loading workpiece 32 quick position is at test position, now treats that material loading workpiece 32 just becomes workpiece for measurement 40 simultaneously.Carrying roller 38 rotates fixed angle at every turn, often rotate once, treating that the measured workpiece of material loading workpiece 32 position delivers to test position by being at present, the measured workpiece treated after material loading workpiece 32 being blocked simultaneously, to prevent it from entering test position, equipment is caused to run disorderly.
This device utilizes carrying roller 38 that measured workpiece is delivered to test position, utilize again carrying roller to block measured workpiece just after test piece simultaneously, time concurrent activity when measured workpiece so just can be utilized to test, namely allow the workpiece measured workpiece below tested while previous measured workpiece is tested, move to the position of workpiece 32 to be tested, test when measured workpiece completes and after leaving test position, just measured workpiece can be moved to test position from the position of workpiece 32 to be tested at once like this.Can greatly improve integrated testability efficiency like this.
After workpiece test position fix sensor 29 receives signal, illustrate that workpiece arrives test position, now workpiece starts to rotate under the effect of rotating axis component 19, material loading is allowed to assist blow gun 22 to stop blowing also simultaneously to cylinder part 25 signal, allow cylinder 27 retract, when cylinders retract receives signal to level sensor 35, illustrate that cylinders retract puts in place, give camera trigger command by industrial computer 15 and panel box 13, start to scan to workpiece test of taking pictures.
After being completed, assisting blow gun 30 signal by industrial computer 15 and panel box 13 to blanking, workpiece for measurement 40 is delivered on belt 36, after workpiece blanking receives signal to level sensor 28, illustrate that now workpiece for measurement has become blanking and to put in place workpiece 41.
Now, in order to ensure equipment operating efficiency, cylinder 27 can be allowed to stretch out, receiving signal when cylinder reaches level sensor 34, namely aforementioned activities completes a circulation.
Instantly expect that a workpiece 41 is defective workpiece through industrial computer analysis, drive advance by belt 36, after workpiece rejecting alignment sensor 26 receives signal, namely can be rejected by defective workpiece blow gun 24.
The difficult point that cylinder (pipe) workpiece side (post) face open defect detects is that its detection faces is cambered surface and on-plane surface, relative to outward appearance defects detection in plane, much more difficult in image acquisition and process.
The utility model can be by the following technical solutions.
Devise synchronously two or more rotating cylinders homodromal or movement means and be detected that workpiece is incorgruous with it at the uniform velocity to be rotated, workpiece side (post) face is converted to rectangular surfaces through shooting under this motion state, again through image processing and analysis, identify workpiece side (post) face open defect and flaw, and reject the workpiece of band defectiveness and flaw.
These two or more rotating cylinders or rotatable parts can correspond to rotating axis component 19 above-mentioned.
