[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Please also read Figure 1 and Figure 2 Now, the pharmaceutical clarity detection device based on electronic computer control provided by the present invention is described.

[0020] There is another disadvantage of the manual testing method. During the manual testing process, the staff needs to rotate the packaging bottles of the medicine to be tested at different times. At this time, the bottle body will rotate while the liquid medicine remains still, or the liquid medicine will shake, which will affect the detection effect.

[0021] Therefore, the electronic computer-controlled medicine clarity detection device provided by the present invention includes a housing 10, a linear drive structure 30, an image collection unit 40 and an image processing unit. The housing 10 has a housing 11 with an open side. A lower light box 20 is provided at the bottom of the housing 11, and a plurality of lower light-transmitting parts are provided at the top of the lower light box 20. The linear drive structure 30 is arranged in the housing 11 and has a sliding part 31. The image collection unit 40 is connected to the sliding part 31, has an upper light-transmitting part arranged vertically, and also has an image collection part that is spaced from the upper light-transmitting part along the open direction of the housing 11. The image collection unit 40 can move under the drive of the linear drive structure 30, and after the upper light-transmitting part corresponds to one of the lower light-transmitting parts, the image collection unit takes a picture of the medicine bottle placed on the lower light-transmitting part. The image processing unit is electrically connected to the linear drive structure 30 and the image collection unit 40, respectively, and can perform clarity analysis on the image collected by the image collection unit 40.

[0022] The pharmaceutical clarity detection device based on electronic computer control provided by the present invention has a working principle that a lower light box 20 is arranged at the bottom of the accommodating cavity 11 on the housing 10, and a plurality of lower light-transmitting parts are arranged on the lower light box 20, and the lower light-transmitting parts can be placed on the pharmaceutical to be tested. The linear drive structure 30 can drive the image collection unit 40 to move between the lower light-transmitting parts. When the upper light-transmitting part in the image collection unit 40 corresponds to one of the lower light-transmitting parts, the upper light-transmitting part and the lower light-transmitting part will provide light in two directions. At this time, the image collection part in the image collection unit 40 will collect the image of the pharmaceutical to be tested, and at the same time, the collected data will be transmitted to the image processing unit. The image processing unit compares the captured image with the standard sample, and then detects the clarity. After the pharmaceutical on the lower light-transmitting part is detected, the linear drive structure 30 will drive the image collection unit 40 to move to the next lower light-transmitting part. At this time, the staff can take out the tested pharmaceutical and place a new pharmaceutical to be tested.

[0023] Before testing begins, standardized sampling of the reagents is required.

[0024] The image processing unit may include an electronic computer and image processing software installed in the electronic computer, that is, the acquisition and processing of images need to be completed under the control of the electronic computer. The image processing software may include an SDK corresponding to the image collection unit and related general analysis software, specifically covering the display of the acquired images, and performing clarity detection based on the transmitted light intensity method (measuring the average gray value of the transmitted light, the higher the turbidity, the lower the transmittance). The detection method using the transmitted light intensity method can be consistent with the detection method of manual naked eye observation, which is a prior art and will not be repeated here.

[0025] Compared with the prior art, the pharmaceutical clarity detection device based on electronic computer control provided in this embodiment can drive the image collection unit 40 to move in the accommodating cavity 11 of the housing 10, corresponding to each lower light-transmitting portion in turn, and collect images of the test agent placed on each lower light-transmitting portion through the image collection unit 40, and then transmit the image to the image processing unit for analysis and detection. The device can adapt to large-scale pharmaceutical detection work, and can also reduce manpower input, improve detection efficiency, and has strong practicality.

[0026] In this embodiment, an illuminance meter is required for initial operation. The illuminance meter can be installed in the image acquisition unit to detect the illuminance of the area where the image acquisition unit is located after the upper light-transmitting part corresponds to the lower light-transmitting part, thereby ensuring that the illuminance is adjusted to an appropriate level.

[0027] It should be noted that the linear drive structure 30 can be a rodless cylinder, in which case its connecting block is the sliding connection 31. Of course, it can also be a lead screw slider structure, in which case the slider is the sliding connection 31. The above structures are all prior art and will not be described in detail here.

[0028] As for the housing 10, an existing clarity tester may be directly used, and the model may be YB-II.

[0029] In some embodiments, the lower light box 20 may be Figure 1 and Figure 7 See the structure shown. Figure 1 and Figure 7 The lower light box 20 includes a box body 21 and a lower light-transmitting plate 22. The box body 21 has an inner cavity, and a lower light source 23 is arranged in the inner cavity of the box body 21. The top of the box body 21 has a platform, and a plurality of first openings communicating with the inner cavity of the box body 21 are arranged on the platform at intervals. There are a plurality of lower light-transmitting plates 22, and each lower light-transmitting plate 22 is respectively arranged at each first opening, and the lower light-transmitting plate 22 is a lower light-transmitting portion.

[0030] A lower light source 23 is arranged in the inner cavity of the lower light box 20. The lower light source 23 may include multiple LED lamp tubes. The lower light box 20 is made of black opaque material. A lower light-transmitting plate 22 is installed on each first opening. The lower light-transmitting plate 22 may be made of white resin material and serves as a horizontal background light source. A uniform backlight is formed through diffuse reflection of the white resin, which can ensure that the bottom of the drug to be tested is illuminated, thereby ensuring the detection effect.

[0031] In some embodiments, the lower light source 23 may be Figure 7 See the structure shown. Figure 7 The lower light source 23 is electrically connected to the image processing unit. The lower light source 23 can adjust the light under the control of the image processing unit, thereby ensuring that the illumination formed by the lower light-transmitting plate 22 and the upper light-transmitting portion is appropriate.

[0032] In some embodiments, the image collection unit 40 may be implemented as follows: Figures 2 to 3 See the structure shown. Figures 2 to 3The image collection unit 40 includes a hanging plate 41, an upper light box 42, an upper light-transmitting plate 43, an outer mounting cover 44 and an image sensor 45. The hanging plate 41 is fixedly connected to the sliding portion 31, and has two ends along the opening direction of the accommodating chamber 11. The end close to the opening of the accommodating chamber 11 is set as the outer end, and the end away from the opening of the accommodating chamber 11 is set as the inner end. The upper light box 42 is arranged below the hanging plate 41 along the vertical direction, and the top end is connected to the inner end of the hanging plate 41. The upper light box 42 has an inner cavity, and an upper light source 46 is arranged in the inner cavity of the upper light box 42. The upper light box 42 has a side wall arranged to be open toward the accommodating chamber 11, and a second opening connected to the inner cavity of the upper light box 42 is provided on the side wall of the upper light box 42. The upper light-transmitting plate 43 is arranged at the second opening, and the upper light-transmitting plate 43 is the upper light-transmitting portion. The outer mounting cover 44 is arranged below the hanging plate 41 along the vertical direction, and the top end is connected to the outer end of the hanging plate 41. The outer mounting cover 44 has an open cavity which is opened toward the upper light-transmitting plate 43. The image sensor 45 is fixed inside the open cavity and is electrically connected to the image processing unit, so as to be able to photograph the medicine to be tested placed on the lower light-transmitting portion.

[0033] The upper light box 42 and the outer mounting cover 44 are spaced apart in the direction of the opening of the accommodating cavity 11 to form a shooting space therebetween. The shooting space is a through-channel structure and is through-set in the moving direction of the hanging plate 41. This ensures that when the hanging plate 41 drives the upper light box 42 and the outer mounting cover 44 to move, the bottled medicine to be tested enters the shooting space to avoid interference. At the same time, the outer mounting cover 44 can also block most of the external light to ensure the detection effect and improve the detection efficiency.

[0034] A distance of 1 mm to 2 mm may be left between the bottom end of the upper light box 42 and the top end of the lower light box 20 .

[0035] An upper light source 46 is provided in the inner cavity of the upper light box 42. The upper light source 46 may include multiple LED lamp tubes. The upper light box 42 is made of black opaque material. An upper light-transmitting plate 43 is installed on each second opening respectively. The upper light-transmitting plate 43 may be made of white resin material. The upper light-transmitting plate 43 is vertically arranged as a vertical background light source. A uniform backlight is formed by diffuse reflection of the white resin. After moving to correspond to the lower light-transmitting plate 22, the lower light-transmitting plate 22 provides a light-emitting surface at the bottom and back of the bottled medicine to be tested, respectively, to ensure sufficient light and thus ensure the detection effect.

[0036] An image sensor 45 is disposed in the outer mounting cover 44. The image sensor 45 can take a picture of the bottled medicine to be tested and transmit the image to an image processing unit in an electronic computer. The lens of the image sensor 45 can be disposed obliquely downward to ensure that it corresponds to the upper light-transmitting plate 43 and the lower light-transmitting plate 22, thereby ensuring the detection effect. The outer mounting cover 44 needs to be black.

[0037] In this embodiment, the moving start and stop positions of the hanging plate 41 can be achieved by laser ranging or laser beam sensors. This technology is existing technology and will not be described in detail here.

[0038] In some embodiments, the upper light source 46 may be a Figure 6 See the structure shown. Figure 6 The upper light source 46 is electrically connected to the image processing unit, and the upper light source 46 can adjust the light under the control of the image processing unit, thereby ensuring that the illumination formed by the upper light-transmitting plate 43 and the lower light-transmitting plate 22 is appropriate.

[0039] In some embodiments, the image sensor 45 may be configured as follows: Figure 6 See the structure shown. Figure 6 , the image sensor 45 is an industrial camera.

[0040] In this embodiment, the industrial camera may be Blackfly S BFS-PGE-31S4C-C, which can be embedded in a small space. The industrial camera can effectively reduce glare and reflection and improve image quality. Correspondingly, the SDK can directly use FLIR Spinnaker to control the parameters of the industrial camera, such as exposure, gain, and trigger mode.

[0041] In some embodiments, see Figures 2 to 5 The pharmaceutical clarity detection device based on electronic computer control also includes a shielding mechanism 60, which includes an inner vertical bar 61, an outer vertical bar 62, a fixed cylinder 63, a rotating shaft 64, a shading cloth 65 and a driving assembly 66. There are two inner vertical bars 61, and the two inner vertical bars 61 are fixed on the side wall of the upper light box 42 along the vertical direction, and are respectively arranged on both sides of the second opening. Each inner vertical bar 61 has an inner vertical slide 611 with an opening facing the outer mounting cover 44. There are two outer vertical bars 62, and the two outer vertical bars 62 are fixed on the outer mounting cover 44 along the vertical direction, and correspond to the two inner vertical bars 61 one by one. Each outer vertical bar 62 has an inner vertical slide 611 with an opening facing the upper light box 42. The corresponding inner vertical slide 611 and the outer vertical slide 621 are combined to form a sliding space. There are two fixed cylinders 63, both of which are fixed on the hanging plate 41. Each fixed cylinder 63 has a cylinder cavity, and a material outlet communicated with the cylinder cavity is provided at the bottom end of the fixed cylinder 63. The material outlet is provided corresponding to the communication port provided on the hanging plate 41. There are two rotating shafts 64, which are respectively rotatably provided in the fixed cylinder 63. There are two shade cloths 65, which are respectively corresponding to the two rotating shafts 64. One end of each shade cloth 65 is fixed on the corresponding rotating shaft 64, and the other end enters the corresponding sliding space after passing through the material outlet and the communication port.

[0042] The driving assembly 66 is connected to the two rotating shafts 64, and can drive the rotating shafts 64 to rotate and retract the shading cloth 65 into the corresponding cylinder cavity after the image collecting unit 40 completes shooting and moves to the next lower light-transmitting portion. Alternatively, when the image collecting unit 40 moves to the next lower light-transmitting portion, it can drive the rotating shafts 64 to rotate and release the shading cloth 65 into the corresponding sliding space.

[0043] The inner end of the hanging plate 41 is connected to an upper light box 42, and the outer end is connected to an outer mounting cover 44, and a shooting space with a through-channel structure is formed between the two along the sliding direction of the sliding connection portion 31 of the linear drive structure 30. Therefore, when the industrial camera takes pictures, there will be the influence of light from both sides of the shooting space, which will affect the shooting effect and thus make the detection effect worse. Based on this, the present embodiment provides a shielding mechanism 60, which can shield the two through openings of the shooting space through two shading cloths 65, and then together with the upper light box 42 and the outer mounting cover 44, the bottled medicine to be tested is packaged therein, thereby effectively avoiding the influence of external light on the shooting of the industrial camera and ensuring the shooting effect.

[0044] However, it also involves the movement of the image collection unit 40, in order to avoid the interference of the shading cloth 65 with other bottled medicines to be tested. Two fixed cylinders 63 are provided, and the two fixed cylinders 63 are connected to the rotating shaft 64. The two rotating shafts 64 are respectively connected to the two shading cloths 65. The rotating shaft 64 can roll up the shading cloth 65 into the cylinder cavity under the drive of the driving component 66 and during the rotation process, so as to open the two ends of the shooting space, and ensure that the bottled medicines to be tested move relatively to the shooting space. The inner vertical slide groove 611 of each inner vertical bar 61 can accommodate one side of the shading cloth 65, and the outer vertical slide groove 621 of each outer vertical bar 62 can accommodate the other side of the shading cloth 65, so as to ensure that the shading cloth 65 can be completely sealed. The corresponding inner vertical slide groove 611 and the outer vertical slide groove 621 will form a sliding space, which can ensure the guidance of the lifting process of the shading cloth 65.

[0045] In some embodiments, the drive assembly 66 may be configured as follows: Figure 1 and Figure 4 See the structure shown. Figure 1 and Figure 4The driving assembly 66 includes a back plate 661, a column 662, a gravity block 663, a winding drum 664 and a flexible rope 665. The back plate 661 is fixedly mounted on the inner wall of the accommodating cavity 11 and arranged along the driving direction of the linear driving structure 30. The back plate 661 is provided with a plurality of limiting surfaces connected in sequence, and each limiting surface corresponds to each spacing area formed between any two adjacent lower light-transmitting parts. Each limiting surface includes two upper planes 666, a lower plane 667 located below the two upper planes 666 and between the two upper planes 666, and an inclined surface 668 located on both sides of the lower plane 667 and connected to the two upper planes 666. The column 662 is vertically arranged and fixedly connected to the upper light box 42. The column 662 has a guide groove that is arranged through the vertical direction and has a vertical sliding opening connected to the guide groove. The gravity block 663 is slidably arranged in the guide groove and has a limiting wheel that can extend out of the vertical sliding opening and is rollingly connected to the limiting surface. There are two winding drums 664, and both winding drums 664 are coaxially connected to the two rotating shafts 64. There are two flexible ropes 665, and each flexible rope 665 corresponds to each winding drum 664 one by one. One end of each flexible rope 665 is connected to the winding drum 664, and the other end is connected to the gravity block 663 through the wire column provided on the hanging plate 41.

[0046] First, a spacing area will be formed between any two adjacent lower light-transmitting parts, and each spacing area corresponds to a limiting surface, and each limiting surface is smoothly connected by the upper plane 666. Each limiting surface includes two upper planes 666, a lower plane 667 located between the two upper planes 666, and two inclined planes 668. The limiting surface is used for the limiting wheel of the gravity block 663 to roll and contact. The gravity block 663 itself has gravity and can continue to maintain contact with the limiting surface during the movement of the image acquisition unit. Therefore, when the light-shielding cloth 65 is located in the sliding space during the shooting process, the limiting wheel on the gravity block 663 is in contact with the upper plane 666. As the image acquisition unit moves, the gravity block 663 will pass through the first inclined plane 668. At this time, the gravity block 663 will continue to move downward, thereby pulling the flexible rope 665. The flexible rope 665 wound on the winding drum 664 pulls the rotating shaft 64 to rotate, so as to achieve the winding of the shading cloth 65, and avoid interference and collision with the bottled medicine on the lower light-transmitting part that has been tested. When the gravity block 663 passes through the lower plane 667 and enters another inclined plane 668, the gravity block 663 will pass through the second inclined plane 668. At this time, the gravity block 663 will continue to move upward, and the shading cloth 65 will be unwound on the rotating shaft 64 due to its own gravity. Then the shading cloth 65 will gradually slide into the sliding space to achieve the sealing of the shooting space, and the flexible rope 665 will be wound on the winding drum 664.

[0047] The setting of the driving component 66 can adjust the rise and fall of the shading cloth 65 according to the movement of the image acquisition unit, without the need for external power, with strong linkage, and can effectively avoid the interference between the shading cloth 65 and the bottled medicine to be tested.

[0048] In some embodiments, the shading cloth 65 may be Figure 4 and Figure 5 See the structure shown. Figure 4 and Figure 5 A gravity column 67 is provided at the end of each shading cloth 65 , and the weight of the gravity column 67 is equal to the weight of the gravity block 663 .

[0049] The gravity column 67 is horizontally disposed and arranged between the corresponding inner vertical bar 61 and outer vertical bar 62 . The gravity column 67 can increase the gravity of the shade cloth 65 , while ensuring that the shade cloth 65 can be flattened and improving the flexibility of the unwinding process of the shade cloth 65 .

[0050] It should be noted that flexible rubber strips may be provided on the two sides of each shading cloth 65 , which are respectively located in the inner vertical slide groove 611 and the outer vertical slide groove 621 , so as to prevent the shading cloth 65 from being separated from the inner vertical strip 61 or the outer vertical strip 62 .

[0051] In some embodiments, the lower light-transmitting portion may be formed as follows: Figure 1 See the structure shown. Figure 1 Each lower light-transmitting portion has a sponge pad 50 on both sides corresponding to the two shading cloths 65. The sponge pad 50 can prevent the gravity column 67 from having a hard contact with the lower light box 20. At the same time, the sponge pad 50 has a certain elasticity and can form a depression under the pressure of the gravity column 67 to ensure the sealing effect between the two, thereby ensuring the shading effect.
