It should be noted that, the first transfer mechanism 3 grabs the workpiece 20 to be detected in the loading material bin 1, and places the workpiece 20 on the workpiece positioning mechanism 4, after positioning, the direction and angle of the workpiece are determined by the workpiece positioning mechanism 4, and the first transfer mechanism 3 grabs the workpiece 20 again, and transfers the workpiece to the front visual inspection component for inner cavity (front) inspection. The front detection structure is a high-definition camera, the inner cavity (front) is shot through adjustment of software control parameters such as angles and exposure, and the shot images are collected to a picture library for defect identification and judgment.
The first transfer mechanism 3 can leave immediately after completing the one-position transfer operation of any one workpiece 20, and process (grasp, adsorb) another workpiece 20 to form the beat coordination of the operation processes. For example, after the workpiece 20 is moved to the rotary index plate 7 by the front vision inspection unit 5, the workpiece can be returned to the starting point, and the next workpiece 20 in the loading magazine 1 can be processed. The same applies to the second transfer mechanism 8 and the third transfer mechanism 17.
The workpiece 20 rotates on the rotary indexing disc, moves to the back dust removal mechanism 18 for surface cleaning, then rotates to the back detection position, is detected by the back visual detection assembly 6, and rotates to the blanking position after detection. At this time, the second transfer mechanism 8 operates to transfer the workpiece 20 to the size detection unit 9 so that the size detection unit 9 can detect the workpiece;
then, the third transfer mechanism 17 picks up the precisely positioned workpiece 20 from the size detection unit 9, and moves the workpiece to the R-angle detection unit 10 to perform R-angle flaw detection. After the detection is completed, the third transfer mechanism 17 combines the results of the detection stations according to a plurality of detection results received by the controller 500 to generate and feed back final detection results including a type a good product (i.e., a good product), a type B good product, a defective product, and defective products with sizes needing to be reworked, classifies and boxes the products, and completes a detection process. The A-type good products are placed into a good product material bin 11, the B-type good products are placed into a B-type material bin 12, defective products with sizes needing to be reworked are placed into a size defect reworking bin 14, defective products are placed into an NG product bin 16, an empty tray bin 13 for emptying is used for containing empty trays, and a spare material bin 15 is used for spare storage.
It should be noted that, in the present application, after the detection is completed, each detection mechanism and each detection assembly may directly send the shooting result or the detection result to the controller 500, the controller 500 comprehensively evaluates each workpiece 20 according to each detection result, and finally, the third transfer mechanism 17 is controlled to place the workpiece 20 into the corresponding bin according to the evaluation result, so as to complete the detection and the screening of the material. In the process, the rhythm of the working procedure can be controlled, and each transfer mechanism can not stop at all.
All the bins of the overall dimension detection equipment (including the material loading bin 1, the material loading empty tray bin 2, the empty tray bin 13 for discharging and 5 discharging bins after detection is completed) are positioned on the long side and the short side of the L-shaped bin, and optionally, the door body 191 (with a locking device) can be opened in a horizontal push-pull mode, so that the material trays can be conveniently replaced. Optionally, among the above-mentioned blowing was accomplished with empty storehouse 13 and 5 detections, three was openly the opening, and three groups are the side opening, and optionally, the NG feed bin contains soft inner wall to and the slope is used in the unloading buffering, and the feed bin is not changed in easy NG material collection.
