Plastic Bottle Appearance InspectionEquipment using visual technology to bottle body and cap breakage, stains, spots, multi-glue, less glue, deformation and other appearance defects for automatic detection.

Plastic bottle appearance testing equipment using visual technology to bottle body and cap breakage, stains, spots, multi-glue, less glue, deformation and other appearance defects for automatic detection.

Pharmaceutical industry on the manufacture and testing of medicine bottle requirements are very high, requires the appearance of the bottle, surface defects, size, foreign bodies, threads, lack of glue, multi-glue, deformation, scraping, color difference and other defects of the total inspection. The traditional practice is an injection molding machine equipped with 1-2 workers for artificial visual inspection, high labor costs or second, the quality of manual testing is extremely unstable, especially night shift of bad products on the outflow of more, directly invite customers to bulk complaints and returns.

The plastic bottle appearance testing equipment uses the visual technology to carry on the automatic detection of the above defects automatically without human intervention, automatic loading and unloading, automatic to the quality of the medicine bottle according to the Grade judgment and classification of the material, detection of stable miscalculation rate is low, high detection efficiency, a device can usually complete two injection molding machinePlastic Bottle Vision InspectionTask, really do 24 hours of non-stop production.

First, the detection object:
1) Product Category: To meet a variety of changes in size slightly.
2) Product size: Recommended height and diameter range (mm): 60~90mm, 40~60mm.
3) Product color: white, milky milk, porcelain white, transparent, slightly with a little gray can be, that is, the color is not too deep.
4) Common machine: to meet the customer 2 injection molding machine sharing a testing machine.
5) Common conditions: When working together, due to the program switching and simple fixture adjustment, the two machines do the same size as possible or close to the product.

Second, the detection effect of the picture:
1) as shown in the figure above, when the plane section of the bottle is not full due to insufficient pressure or other reasons, the image presented by it is missing, but also not full, the inner and outer circles in the figure have this phenomenon, can be clearly seen and detected.

2) Use the correct lighting to detect the contour of the product is very good, can shine a very clear contour

3) using the correct illumination, the black spot on the bottle can be detected regardless of the rotation angle.

4) using the correct illumination, the bottom black spot in the red circle can be detected.

5) Bottle mouth defect: Because there are multiple cameras on the side, it can be easily detected at any angle.

6) key dimension detection.

7) as shown in the figure, the bottle mouth part has a good contrast, the internal and external diameter of the screw teeth can be accurately measured.

8) as shown in the figure above, the use of the correct light source and lens bottle mouth inner diameter part and the bottle mouth has a better contour comparison, the diameter of the bottle mouth can be accurately measured.

Third, the general mechanism of equipment diagram:
1) The material of 2 injection molding machine is expected to be on the belt by simple manipulator;
2) The material on the belt is on the turntable;
3) The turntable has a variety of functions, including detection and feeding.
4) Detection function: Side 3 cameras, up and down 2-3.
5) Feeding function: Ok accurate count, Ng accurate count of the material.
6) This scheme has a small footprint and can meet a full range of testing.
