The utility model discloses appearance imperfections inspection device's working process as follows: the workpiece to be inspected is a circular ring-shaped sheet workpiece, firstly, the workpieces to be inspected are all poured into the disc type vibration feeding machine 1, the disc type vibration feeding machine 1 conveys the workpieces into the linear vibration feeding machine 2 one by one after working, the blowing pipe 3 blows high-speed air towards the direction of the inspection mechanism assembly according to a certain time interval (the time interval can be determined according to the production takt of the subsequent inspection mechanism assembly), and thus, one workpiece is blown to the outlet of the linear vibration feeding machine 2 and falls on the feeding jig 28 every time, so that the workpieces can be prevented from being stacked mutually, and meanwhile, only one workpiece is sent to the feeding jig 28 every time (the traveling speed of the blown workpiece is greater than that of the subsequent workpiece).
After the workpiece is in place, the feeding mechanism works, the first pneumatic clamping jaw 25 (closest to the feeding direction) grabs the workpiece and conveys the workpiece to the first inspection jig 10 (closest to the feeding direction), and the first front industrial camera 6 photographs the front of the workpiece under the condition of illumination; then the second pneumatic clamping jaw 25 picks up the workpiece again and conveys the workpiece to the second inspection jig 10, the second front industrial camera 7 photographs the front of the workpiece under the condition of no illumination, and in the action process, the first pneumatic clamping jaw 25 conveys the second workpiece from the feeding jig 28 to the first inspection jig 10; then the third pneumatic clamping jaw 25 will grab the first workpiece and drive the workpiece to turn 180 ° under the action of the rotary cylinder 26, and place the turned first workpiece on the third inspection jig 10, the first back industrial camera 8 will take a picture of the back of the first workpiece under the condition of illumination, and at this moment the second workpiece has already been transported to the second inspection jig 10, and take a picture of the front of the workpiece under the condition of no illumination; meanwhile, the third workpiece is conveyed to the first inspection jig 10, and front-side photographing is performed under the illumination condition; the first workpiece is taken the picture of the reverse side under the action of the second reverse side industrial camera 9 and under the condition of no illumination, and finally taken away by the last pneumatic clamping jaw 25 and put into a collecting container arranged at the tail end of the feeding mechanism,
that is to say, the feeding mechanism will gradually transport one workpiece from the feeding fixture 28 to the four inspection fixtures 10 behind, and the different industrial cameras will take photos of the front and back sides of the workpiece under different environments, the control system of the device will automatically compare the taken photos with the standard images, if there is a problem, the device will stop working, and the operator will detect which specific workpiece is unqualified through observation and sort out the unqualified workpiece;
in the feeding mechanism, an X-axis cylinder 11 can directly drive an X-axis sliding seat 12 to do reciprocating linear motion along the X-axis direction;
when the Y-axis cylinder 13 works, the parallelogram mechanism formed by the Y-axis linkage rod 14 and the two first swing rods 15 is driven to act, and further the Y-axis push-pull rod 16 is driven to swing in space, so that the Y-axis push-pull rod 16 drives the Y-axis slide block 17 to act, but because the Y-axis slide block 17 is connected on the slide way arranged along the Y-axis direction in a sliding way, the Y-axis slide block 17 can do reciprocating linear motion along the Y-axis direction under the guiding action of the slide way,
when the Z-axis cylinder 19 works, the Z-axis linkage rod 20 and the two second swing rods 21 form a parallelogram motion to drive the Z-axis push-pull rod 22 to swing in space, so that the Z-axis push-pull rod 16 drives the Z-axis slider 23 to move, but because the Z-axis slider 23 is connected on a slide way arranged along the Z-axis direction in a sliding way (the slide way is positioned on the Z-axis support plate 18), the Z-axis slider 23 can do reciprocating linear motion along the Z-axis direction under the guiding action of the slide way,
the combination of the three movements drives the clamping jaw supporting plate 24 supported on the two Z-axis sliding blocks 23 to act on a three-dimensional space,
under the drive of the driving mechanism in the feeding mechanism, the clamping jaw supporting plate 24 drives all the pneumatic clamping jaws 25 thereon to move spatially, and the specific movement process is as follows: in the initial state, the clamping jaw supporting plate 24 is at a position far away from the disc type vibration feeding machine 1 and is at a low position; when the device works, the X-axis cylinder 11 works, the clamping jaw supporting plate 24 moves for a unit distance towards the direction of the disc type vibration feeding machine 1, then the Y-axis cylinder 13 works to drive all the pneumatic clamping jaws 25 to move towards the direction close to the jig, and after the movement is in place, the Z-axis cylinder 19 works to drive the pneumatic clamping jaws 25 to descend and grab workpieces on the corresponding jig;
then the Z-axis cylinder 19 moves reversely to drive all the pneumatic clamping jaws 25 to lift upwards (the workpiece can be separated from the jig only after being lifted upwards), the Y-axis cylinder 13 moves reversely to drive all the pneumatic clamping jaws 25 to move towards the direction far away from the jig, then the X-axis cylinder 11 moves reversely to drive all the pneumatic clamping jaws 25 to return to the initial position (at the moment, the workpiece is at a high position),
then, the Y-axis cylinder 13 acts again, all the pneumatic clamping jaws 25 return to the upper part of the jig, the Z-axis cylinder 19 acts, the pneumatic clamping jaws 25 descend and put down the workpiece to be detected on the corresponding jig,
it should be noted that when the pneumatic clamping jaw 25 is empty, a working cycle is required to be set aside for the rotating cylinder 26 to act, so as to realize the turning operation of the workpiece to be detected.
