Description

Technical Field

[0001] The present invention relates to the technical field of packaging detection, in particular to a visual detection device for drug packaging. Background Art

[0002] Pharmaceutical packaging is usually very strict because it involves product safety issues, which are usually reflected in the printed graphics on the outside of the packaging box. The printed graphics contain important information such as the drug manufacturer, production date, and drug inspection code. In order to avoid fading of the printed graphics on the drug packaging box during transportation and storage, there are certain requirements for the quality of the printed graphics, and the quality of the printed graphics needs to be tested.

[0003] At present, the appearance inspection of drug packaging is that two cameras perform appearance inspection on 5 sides of the drug packaging. One camera can inspect up to 3 sides. The bottom surface of the drug packaging and the contact surface of the belt are the blind areas of the inspection. In order to solve the problem of blind areas of inspection, a gap between drug packages is usually left on the conveyor belt, and a transparent glass plate is installed. A third camera is added to the bottom of the transparent glass plate for inspection. Due to the large amount of inspection, the transparency of the transparent plate is reduced after wear, which seriously affects the accuracy of imaging inspection and must be replaced frequently. At the same time, due to the large friction of the transparent glass plate, it is easy to produce connected packages at the transparent plate, and it is impossible to accurately remove all drug packages with quality defects.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a visual inspection device for pharmaceutical packaging is proposed. Summary of the invention

[0007] Furthermore, a motor 1 is fixed to the outer side of the side plate on one side, and a rotating plate is fixedly connected to the output end of the motor 1, and the rotating plate is rotatably installed on the inner side of the side plate on the other side through a bearing.

[0008] Furthermore, infrared distance sensors are provided at the middle ends of both sides of the rotating plate, and two groups of upper and lower jacks are symmetrically provided on both sides of the rotating plate.

[0009] Furthermore, an insertion strip is interference-fitted inside the insertion hole, and the gap between upper and lower adjacent insertion strips matches the height of the medicine package, and the insertion strip matches the avoidance groove between adjacent extension plates.

[0010] Furthermore, a transmission assembly is rotatably installed at both ends of the side plate, and the transmission assembly includes a transmission roller, a belt 1 and a rotating wheel. The transmission roller is rotatably installed at both ends of the side plate, and a belt 1 is sleeved on the outside of the transmission roller. The end of the belt 1 facing away from the transmission roller is rotationally connected to the rotating wheel, and the rotating wheel is rotatably installed at the end of the extension plate.

[0011] Furthermore, the transmission assembly also includes a pulley, a second belt and a second motor. The input end of the transmission roller is coaxially mounted with a pulley, and a second belt is sleeved on the outside of the pulley. The pulleys on both sides are rotationally connected to the output end of the second motor through the second belt.

[0012] Furthermore, a workbench is provided on the other side of the base, and two guide rails are symmetrically fixed on the top of the workbench. A cylinder is fixed on a boss on one side of the workbench, and a push rod is fixedly connected to the output end of the cylinder.

[0013] Furthermore, a sorting component is arranged above the workbench, and the sorting component includes a frame and a slider. The frame is fixedly connected to the output end of the push rod, and sliders are fixed on both sides of the bottom of the frame, and the sliders are slidably matched with the corresponding guide rails.

[0014] Furthermore, the sorting component also includes a through hole, a motor three and a bevel gear.

[0015] Furthermore, the sorting component also includes a bevel gear rod, a roller and a conveyor belt. The bevel gear side is meshed with a bevel gear rod, and rollers are coaxially connected at both ends of the bevel gear rod, and the rollers at the front and rear ends are equipped with conveyor belts.

[0016] The present invention provides a visual inspection device for drug packaging, which has the following beneficial effects:

[0017] 1. During the use of the present invention, the drug package is delivered to the inspection table on one side of the side plate through the conveying device, and the right, upper and front sides of the drug package are photographed by the visual camera on the upper right. Under the rotation transmission of the motor 2 through the belt 2 to the pulleys on both sides, the belt 1 rotating between the transmission roller and the rotating wheel drives the inspected drug package into the gap between the adjacent inserts on one side of the rotating plate. The density of the inserts can be adjusted according to different drug packages to ensure the stability of the flipping process. Then, the drug package is flipped under the rotation drive of the motor 1 on the rotating plate.

The visual camera converts the detected target into an image signal and transmits it to the image processor. The algorithm is further used to process these signals, extracts the characteristics of the target and compares them with the preset allowable degree to identify defective products. The present application replaces the existing technical solution of using a transparent glass plate to solve the detection blind spot by a flip structure. It not only solves the problem that the detection effect is affected by the wear of the transparent glass plate, but also accurately identifies and grasps the drug package through the infrared distance sensor, eliminating the problem of continuous packaging, and only two visual cameras are needed to perform six-sided detection of the drug package, which improves the accuracy of visual detection and effectively reduces the detection cost.

[0018] 2. During the use of the present invention, the motor three in the middle of the frame drives the bevel gear rod to rotate through the output end bevel gear, and then drives the conveyor belts on both sides to rotate synchronously through the roller. Since only one motor three is used, the production cost is effectively reduced. When in use, the quality of the drug packaging is divided by visual inspection. When it is determined to be a qualified product, the conveyor belt on one side corresponding to the qualified product is connected to the operating table, and the drug packaging is sent to the subsequent production link. When it is determined to be a defective product, the cylinder pushes the frame to move above the guide rail through the push rod, and the conveyor belt on the other side corresponding to the defective product is connected to the operating table, so as to realize the sorting and transportation of defective products and qualified products. After the defective drug packaging is removed from the packaging, the contents therein can be recycled for the second time. The present application realizes automatic identification and rejection of defective products by setting a sorting component in cooperation with visual inspection, thereby improving the degree of automation of the drug packaging inspection production line, and has the characteristics of cost saving, simple maintenance and high detection success rate.
