Problems solved by technology

At present, the more direct method is to manually observe the soft bag drug solution with the naked eye, and judge whether the impurities contained in it meet the standards based on the experience of the staff. However, in the actual detection process, the impurities in the normal saline will appear differently due to their different types. Therefore, how to clearly present impurities of different color shades is one of the difficulties in this type of detection method
In addition, it is necessary to manually shake the soft bag liquid medicine before the test to avoid the particle precipitation in the static state from affecting the accuracy of the test results; Larger, resulting in inaccurate test results

Embodiment 1

[0034] refer to Figure 1-6 , the present embodiment is photographed by an automatic photographing device, the device includes a frame, and the opposite top of the frame is provided with a circular conveyor belt 1, the conveyor belt 1 is roughly rectangular, and operates under the action of four pulleys, one of which The belt wheel is a driving wheel. A plurality of hooks 2 are equidistantly arranged on the conveyor belt 1. In the present embodiment, the conveyor belt 1 runs until image 3 During the shown position, there are four hooks 2 on one side of its long side, and one hook is arranged on one side of the short side. The medical medicine bag 3 is generally flat, and there is a neck below the mouth of the bag. The outer diameter of the neck is smaller than the outer diameter of the mouth of the bag. In this embodiment, the feature of the neck is used to hang the soft bag liquid medicine.

[0035] Specifically, the hook 2 has a certain width, its bottom surface is a hori...

Embodiment 2

[0046] The difference between this embodiment and Embodiment 1 is that the turning mechanism is different. During the implementation of the technical solution of Embodiment 1, the applicant found that when the turning speed is too fast, the medicine bag 3 will be thrown out to both sides, so this embodiment provides a preferred embodiment for this problem.

[0047] Specifically, refer to Figure 7 The turning mechanism 9 of the present embodiment includes a lifting cylinder 93, a turning motor 91 and a turning frame 92 connected to the output end of the turning motor. The output end of the lifting cylinder 93 is connected with a mounting plate, and the turning motor 91 is installed on the mounting plate. The reversing frame 92 is a transparent frame with only an opening at the top, that is, the two sides are sealed on the basis of the reversing frame in Embodiment 1, so as to prevent it from being thrown out from both sides when it is flipped quickly. When performing the over...

Embodiment 3

[0049] The difference between this embodiment and Embodiment 1 is that in this embodiment, the conveyor belt 1 is elongated, and the number of three shooting stations in each group of shooting stations is multiple, and the conveyor belt 1 can carry out a conveying action every time. Simultaneously carry out the shooting work of multiple medicine bags on the same shooting station.

[0050] Specifically, refer to Figure 8 , in each group of shooting station groups, the number of flipping shooting stations 6 is 10, and they are arranged side by side according to the spacing of the hooks 2. When 10 medicine bags enter the flipping shooting station 6 respectively, each flipping shooting station 6 will be carried out simultaneously. Flipping and shooting actions, after the shooting is completed, the conveyor belt 1 runs to make the next group of 10 medicine bags enter the flipping and shooting station 6, and cycle in turn, so as to greatly improve the shooting efficiency.

Abstract

The invention discloses a medicine bag foreign matter detecting and shooting method which comprises the steps that a medicine bag is hung on a hook of a conveying belt, and the conveying belt runs to drive the medicine bag to sequentially enter a deep-color shooting station set and a light-color shooting station set to be shot; each shooting station group comprises at least one front shooting station, at least one back shooting station and at least one turnover shooting station, a background plate of the deep-color shooting station group is a deep-color background plate, and a background plate of the light-color shooting station group is a light-color background plate. According to the invention, through two detection stations with different backgrounds, a detection environment for impurities with different color differences can be created, and the comprehensiveness and the accuracy of a detection result can be improved in combination with the shot images of the front side and the back side.

Description

technical field [0001] The invention relates to the technical field of detection of foreign matter in bagged medicinal liquid, in particular to a method for detecting and photographing foreign matter in a medicine bag. Background technique [0002] Many liquid medicines need to be tested for foreign matter after they are bagged to detect whether the impurities contained in them exceed the standard. At present, the more direct method is to manually observe the soft bag drug solution with the naked eye, and judge whether the impurities contained in it meet the standards based on the experience of the staff. However, in the actual detection process, the impurities in the normal saline will appear differently due to their different types. Therefore, how to clearly present impurities of different color shades is one of the difficulties in this type of detection method. In addition, it is necessary to manually shake the soft bag liquid medicine before the test to avoid the partic...
