Description

Technical Field

[0001] The utility model relates to the technical field of liquid medicine quality detection devices and equipment, and specifically provides a light inspection machine. Background Art

[0002] The production of qualified drug solutions is a fundamental requirement for both manufacturers and patients. Tiny shards of glass, rubber, or other insoluble particles in the drug solution typically settle at the bottom of the bottle or float at the top when stationary. Manual testing requires inverting the liquid to create movement, which also drives the movement of solid impurities. These impurities move with the drug to the center, triggering the camera to capture a clear image of the defective product. Alternatively, the presence of impurities can be determined by identifying moving targets. This type of testing requires manual operation, resulting in inaccurate results, low efficiency, and a high labor and time consumption.

[0003] Publication number CN106706658A discloses a medical liquid detection device comprising a CCD camera, an industrial control box, a main switch, an operation panel, an LCD display, connecting cables, an upper bayonet, a lifter, a handle, a controller, a main arm, a rotating bed, a drive shaft, a motor, a base, and a light source box. A connecting cable is connected to the right end of the CCD camera, electrically connecting the industrial control box and the CCD camera. The main switch and operation panel are located on the upper portion of the industrial control box, and the LCD display is located on the upper portion of the industrial control box. The main arm is mounted on a base, which is provided with a light source box. The rotating bed is located on the upper portion of the main arm. This medical liquid detection device features image adjustment buttons on the operation panel that can be used to adjust the glucose solution graph, making the graph clearer. A tempered glass film is provided on the LCD display to protect the LCD. However, when tiny impurities in the medicine bottle sink to the bottom, and the bottle bottom is not illuminated, the CCD camera cannot accurately detect these tiny impurities, resulting in a low detection rate.

[0020] The following is combined with Figure 1-3 The preferred embodiments of the present application are described in detail so that the advantages and features of the present application can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present application. These embodiments are only used to illustrate the present invention and are not intended to limit the present invention.

[0021] The light inspection machine of the present application comprises a workbench 10, a clamping mechanism 20, a rotating mechanism 30, a visual inspection system 40, an illumination mechanism 50, and a control system. Under the control of the control system, the visual inspection system 40 performs imaging inspection on the bottled liquid medicine installed between the clamping mechanism 20 and the rotating mechanism 30. The algorithm is used to check whether there are foreign objects in the bottled liquid medicine, including but not limited to glass fragments, rubber particles, metal, fibers, hair, etc., to ensure the safety of medication and prevent medication accidents. Bottled liquid medicine is mainly inspected in products such as vials, ampoules, and injections. In addition to the pharmaceutical industry, the light inspection machine of the present application can also be applied to the inspection of product liquids in industries such as alcohol, beverages, food, and cosmetics.

[0022] The above-mentioned clamping mechanism 20 and control system are arranged on a workbench 10, and the workbench 10 has a table top 11. Specifically, the rotating mechanism 30 is arranged under the table top 11, and the lighting mechanism 50 illuminates the medicine bottle 1a installed and rotating between the clamping mechanism 20 and the rotating mechanism 30.

[0023] The clamping mechanism 20 comprises a lift actuator 21, a screw 22, a connector 23, an optical axis 24, a pressure plate 25, a bearing 26, a cover 27, a spring 28, and a bracket 29. The lift actuator 21 indirectly raises and lowers the cover 27, allowing the liquid medicine bottle 1a to be placed in or removed from the bottle placement tray 34. The lift actuator 21 is fixed to the workbench 10. The screw 22 is connected to the power output shaft of the lift actuator 21. The screw 22 is threadedly connected to the connector 23. The optical axis 24 is fixed to the connector 23. The pressure plate 25 is fixed to the lower end of the optical axis 24. The pressure plate 25 is sleeved and fixed to the outer ring of the bearing 26. The inner ring of the bearing 26 is fixedly connected to the cover 27. The cover 27 is used to press the liquid medicine bottle 1a. The screw 22 is mounted on the bracket 29, which is fixed to the table 11. The cover 27 is tapered.

[0024] Under the control system, lift actuator 21 begins to rotate, driving screw 22, along with connector 23, optical axis 24, pressure plate 25, bearing 1 26, and cover 27, to rise and fall. As cover 27 rises and falls, liquid medicine bottle 1a can be placed in or removed from cover 27. Spring 28 is positioned on optical axis 24, between connector 23 and pressure plate 25.

[0025] The aforementioned rotation mechanism 30 comprises a rotation driver 31, a drive belt 32, an adapter plate 33, a bottle placing tray 34, a second bearing 35, and a connecting bracket 36. The lifting driver 21 indirectly rotates the bottle placing tray 34, placing the rotating bottle placing tray 34 and the liquid medicine bottle 1a within the imaging range of the imager 41. The rotation driver 31 is fixed to the workbench 10; the rotation driver 31 can also be fixed below the table 11 via the connecting bracket 36. A synchronous pulley 1 is provided on the output shaft of the rotary driver 31. The adapter plate 33 is fixed on the table 11. The adapter plate 33 is used to place the liquid medicine bottle 1a containing the liquid medicine. The bottle placement tray 34 has a hollow rotating shaft 341. The hollow rotating shaft 341 passes through the adapter plate 33 and the table 11. A bearing 2 35 is provided between the hollow rotating shaft 341 and the adapter plate 33. A synchronous pulley 2 is provided on the hollow rotating shaft 341. A transmission belt 32 is provided between the synchronous pulley 1 on the above-mentioned output shaft and the synchronous pulley 2 of the hollow rotating shaft 341.

[0026] Under the control of the control system, the bottle placing tray 34 is pressed by the cover 27 , and the rotary driver 31 starts to rotate and drives the bottle placing tray 34 to rotate via the transmission belt 32 .

[0027] The lighting mechanism 50 has a table light source 51 and a point light source 52. The table light source 51 is set on the table 11. There are several table light sources 51. The table light sources 51 here are not necessarily set on the table 11. In short, the table light sources 51 are distributed around the medicine bottle 1a.

[0028] The light inspection machine also has a cover shell 60, which is fixed under the table 11. The point light source 52 is arranged on the cover shell 60 and is opposite to the center hole 342 of the hollow rotating shaft 341. The light emitted by the point light source 52 can illuminate the bottom of the medicine bottle 1a through the center hole 342 of the hollow rotating shaft 341.

[0029] The visual inspection system 40 includes an imager 41 and a fixed bracket 42. The imager 41 is arranged on the fixed bracket 42, which is fixed on the table 11. The imager 41 is facing the liquid medicine bottle 1a. Under the control of the control system, when the liquid medicine bottle 1a rotates, the imager 41 images the liquid medicine bottle 1a. When there is a point light source 52 at the bottom of the liquid medicine bottle 1a, the image is clearer, thereby improving the detection efficiency of the liquid medicine in the liquid medicine bottle 1a. The light inspection machine of the present application can detect any sediment, suspended matter and floating foreign matter larger than 50 microns in the liquid medicine bottle 1a. Foreign matter includes but is not limited to glass fragments, rubber particles, metal, fiber, hair, etc., especially for the detection of foreign matter mixed with bubbles. It has a unique core recognition technology that can distinguish between bubbles and foreign particles, which can meet the needs of quality control and small batch production. In addition, the light inspection machine can save batch defective images and defective (classification) reports and images, and has a playback detection function, which is sufficient to meet the requirements of CE, EC2006 / 42 / EC MD and other specifications.
