Description

Technical Field

[0001] The invention belongs to the technical field of medicine bottle appearance detection, and specifically relates to a medicine bottle appearance defect detection device. Background Art

[0002] The appearance defect detection of medicine bottles is mainly based on machine vision technology, which is a non-contact, non-destructive and fully automatic detection method. The detection system obtains the surface image of the product through appropriate light sources and image sensors, and uses corresponding image processing algorithms to extract the feature information of the image. This feature information is then used for the location, identification, grading and other discrimination and statistics, analysis and other operations of surface defects, so as to achieve the purpose of eliminating defective products and retaining good products.

[0003] However, when inspecting the appearance defects of medicine bottles, since there is a concave shape between the bottle body and the bottle mouth, a large number of shadows will appear after scanning the appearance of the medicine bottles, especially the concave parts, which leads to poor inspection results. At the same time, the diagonals of the medicine bottles are chamfered, which will cause the inspection thickness of the medicine bottles to vary due to the illumination angle, resulting in inaccurate inspection results. In addition, since medicine bottles are generally transparent, it is easy to see through the bottom side when inspecting the medicine bottles, resulting in unclear defect locations and affecting inspection efficiency.

[0004] In view of this, a device for detecting appearance defects of medicine bottles is proposed. Summary of the invention

After the air bag structure is inflated, the medicine bottle can be rotated by the action of the drive motor and the transmission belt, making it convenient for the detection head to identify different surfaces of the medicine bottle.

[0015] As an optimal technical solution for a device for detecting defects in the appearance of medicine bottles, an air cavity is opened inside the driving shaft, and a piston frame is arranged in the air cavity for telescopic movement.

[0018] 1. The device for detecting appearance defects of medicine bottles controls the docking seat to move toward the position of the medicine bottle through a threaded drive structure, and the spherical disk moves to the inclined section of the extrusion groove. Under the action of the elastic member 3, the linkage column, the hinge frame, the piston frame and the air cavity, the capillary tube injects air into the folding airbag 2, and under the action of the folding airbag 3 and the folding airbag 1, the airbag structure expands as a whole. At this time, the airbag structure is fully expanded to restrict the inner wall of the medicine bottle, which can assist the linkage medicine bottle to move, and avoid the conventional harder clamp from damaging the surface of the bottle when limiting the position of the bottle body;

[0019] 2. The device for detecting appearance defects of medicine bottles drives the gear to rotate by controlling the motor, and meshes with the rack. Under the action of the guide block and the second curved groove, the drive box can also rotate according to the shape of the medicine bottle when it moves, so as to avoid the situation of uneven thickness scanning. The drive shaft can be driven to rotate under the action of the drive motor and the conveyor belt, and the inflated air bag structure can drive the medicine bottle to rotate, so as to better scan and detect the medicine bottle.

[0020] 3. The device for inspecting appearance defects of medicine bottles uses hollow hoses and irradiation lamps arranged at equal angles, so that the irradiation lamps illuminate the medicine bottles from the inside out, making the inspection head more effective in inspecting the bottle body and less likely to cause inaccurate inspection results due to perspective illumination;

[0021] 4. When the medicine bottle appearance defect detection device moves through the docking seat, under the special shape of the triangular groove and the action of the positioning axis, when the air bag structure is separated from the inside of the medicine bottle, the supporting seat can move downward and be squeezed by the linkage frame and the oblique block. At this time, the linkage frame can push the medicine bottle at one end of the supporting seat. At this time, with the cooperation of the guide channel, the medicine bottle enters the flexible frame, so that the medicine bottle after the inspection can be automatically exported, thereby improving the overall efficiency.

At this time, with the cooperation of the guide channel 402, the medicine bottle enters the flexible frame 403. In order to better allow the medicine bottle to enter the flexible frame 403, the size of the support seat 500 can be set to 0.6-0.8 times the size of the medicine bottle.
