[0052] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0053] Please refer to Figure 1 and Figure 2 together, and now a reagent clarity detection device based on computer control provided by the present invention will be described.

[0054] There is also a drawback in the manual detection method. During the manual detection process, the staff needs to rotate the packaging bottle of the reagent to be detected in different ways. At this time, the bottle body rotates while the liquid reagent remains stationary, or the liquid reagent shakes, which will affect the detection effect.

[0055] Therefore, the pharmaceutical clarity detection device controlled by an electronic computer 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 receiving cavity 11 with an open side. A lower light box 20 is provided at the bottom of the receiving cavity 11, and the top of the lower light box 20 has a plurality of spaced lower light-transmitting portions. The linear drive structure 30 is disposed in the receiving cavity 11 and has a sliding portion 31. The image collection unit 40 is connected to the sliding portion 31, has a vertically arranged upper light-transmitting portion, and also has an image collection portion spaced from the upper light-transmitting portion along the open direction of the receiving cavity 11. The image collection unit 40 can move under the drive of the linear drive structure 30, and after the upper light-transmitting portion corresponds to one of the lower light-transmitting portions, the image collection portion takes a picture of the medicine bottle placed on the lower light-transmitting portion. 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 and processing on the images collected by the image collection unit 40.

[0056] For the pharmaceutical clarity detection device controlled by an electronic computer provided by the present invention, the working principle is that a lower light box 20 is provided at the bottom end of the receiving cavity 11 on the housing 10, and a plurality of lower light-transmitting portions are arranged on the lower light box 20, and the lower light-transmitting portions can place the medicine to be tested. The linear drive structure 30 can drive the image collection unit 40 to move between the lower light-transmitting portions. When the upper light-transmitting portion in the image collection unit 40 corresponds to one of the lower light-transmitting portions, the upper light-transmitting portion and the lower light-transmitting portion will provide light in two directions. At this time, the image collection portion in the image collection unit 40 will collect the image of the medicine to be tested, and at the same time transmit the collected data to the image processing unit. The image processing unit compares the captured image with the standard sample to detect the clarity. After the medicine on the lower light-transmitting portion is detected, the linear drive structure 30 will drive the image collection unit 40 to move to the next lower light-transmitting portion. At this time, the staff can take out the tested medicine and place a new medicine to be tested at the same time.

[0057] Before the detection starts, it is necessary to perform standardized sampling on the medicine.

[0058] Regarding the image processing unit, it 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 portion and related general analysis software, specifically covering the display of the collected images, and at the same time 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 light transmittance). The detection method using this transmitted light intensity method is consistent with the method of manual naked-eye observation and detection, which is the prior art and will not be elaborated here.

[0059] Compared with the prior art, the pharmaceutical clarity detection device based on computer control provided by this embodiment enables the linear drive structure 30 to drive the image acquisition unit 40 to move in the accommodation cavity 11 of the housing 10, successively corresponding to each lower light-transmitting part, and the image acquisition unit 40 acquires images of the test agents placed on each lower light-transmitting part, and then transmits the images to the image processing unit for analysis and detection. This device can adapt to a large number of pharmaceutical detection tasks, reduce labor input, improve detection efficiency, and has strong practicability.

[0060] In this embodiment, an illuminometer is required during the initial operation. The illuminometer 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 and the lower light-transmitting part are aligned, so as to ensure that the illuminance is adjusted to an appropriate level.

[0061] It should be noted that the linear drive structure 30 can be a rodless cylinder, and in this case, its connecting block is the sliding part 31. Of course, it can also be a lead screw slider structure, and in this case, the slider is the sliding part 31. The above structures are all prior art and will not be elaborated here.

[0062] Regarding the housing 10, an existing clarity detector can be directly used, and the model can be YB-II type.

[0063] In some embodiments, the above-mentioned lower light box 20 can adopt the structure as shown in Figure 1 and Figure 7 See 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 provided 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 at intervals on the platform. A plurality of lower light-transmitting plates 22 are provided, and each lower light-transmitting plate 22 is respectively arranged at each first opening. The lower light-transmitting plate 22 is the lower light-transmitting part.

[0064] A lower light source 23 is arranged in the inner cavity of the lower light box 20. The lower light source 23 can include a plurality of LED tubes. The lower light box 20 is made of a black light-tight material. Lower light-transmitting plates 22 are respectively installed on each first opening. The lower light-transmitting plate 22 can be made of white resin material. As a horizontal background light source, uniform backlight is formed through the diffuse reflection of white resin, which can ensure that the bottom of the test agent has light, thereby ensuring the detection effect.

[0065] In some embodiments, the above-mentioned lower light source 23 can adopt the structure as shown in Figure 7 See Figure 7 . The lower light source 23 is electrically connected to the image processing unit, and the lower light source 23 can adjust the illumination under the control of the image processing unit, so as to ensure that the illuminance formed by the lower light-transmitting plate 22 and the upper light-transmitting part is appropriate.

[0066] In some embodiments, the above-mentioned image collection unit 40 may adopt the structure as shown in Figures 2 to 3 . Referring to Figures 2 to 3 , the image collection unit 40 includes a suspension plate 41, an upper light box 42, an upper light-transmitting plate 43, an outer mounting cover 44, and an image sensor 45. The suspension plate 41 is fixedly connected to the sliding connection portion 31, and has two ends along the opening direction of the accommodation cavity 11. The end close to the opening of the accommodation cavity 11 is set as the outer end, and the end far from the opening of the accommodation cavity 11 is set as the inner end. The upper light box 42 is arranged below the suspension plate 41 along the vertical direction, and the top end is connected to the inner end of the suspension 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 facing the opening of the accommodation cavity 11, and a second opening communicating with the inner cavity of the upper light box 42 is arranged 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 an upper light-transmitting portion. The outer mounting cover 44 is arranged below the suspension plate 41 along the vertical direction, and the top end is connected to the outer end of the suspension plate 41. The outer mounting cover 44 has an open cavity with an opening facing the upper light-transmitting plate 43. The image sensor 45 is fixedly arranged inside the open cavity and is electrically connected to the image processing unit, and can photograph the test agent placed on the light-transmitting portion.

[0067] The upper light box 42 and the outer mounting cover 44 are arranged at intervals in the opening direction of the accommodation cavity 11, and a photographing space is formed between the two. The photographing space is a through-channel structure and is through in the moving direction of the suspension plate 41, which can ensure that during the movement of the suspension plate 41 driving the upper light box 42 and the outer mounting cover 44, the bottled test agent enters the photographing space to avoid interference. At the same time, the outer mounting cover 44 can also block most of the external light, ensuring the detection effect and improving the detection efficiency.

[0068] A distance of 1 mm - 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.

[0069] An upper light source 46 is arranged in the inner cavity of the upper light box 42. The upper light source 46 may include a plurality of LED tubes. The upper light box 42 is made of a black light-impermeable material. Upper light-transmitting plates 43 are respectively installed on each second opening. The upper light-transmitting plate 43 may be made of white resin material. The upper light-transmitting plate 43 is arranged vertically and serves as a vertical background light source. Uniform backlight is formed through the diffuse reflection of white resin, and after moving to correspond to the lower light-transmitting plate 22, the upper light-transmitting plate 43 and the lower light-transmitting plate 22 respectively provide light-emitting surfaces at the bottom and back of the bottled test agent, ensuring sufficient light and thus ensuring the detection effect.

[0070] An image sensor 45 is disposed inside the outer mounting cover 44. The image sensor 45 can take pictures of the medicine to be tested in the bottle and at the same time transmit the images to the image processing unit in the electronic computer. The lens of the image sensor 45 can be set obliquely downward, so as to ensure corresponding 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.

[0071] In this embodiment, regarding the moving start and stop positions of the hanging plate 41, it can be realized by laser ranging or laser pair sensors. This technology is an existing technology and will not be elaborated here.

[0072] In some embodiments, the above upper light source 46 can adopt, for example Figure 6 the structure shown. Refer to Figure 6 , the upper light source 46 is electrically connected to the image processing unit, and the upper light source 46 can adjust the illumination under the control of the image processing unit, so as to ensure that the illumination formed by the upper light-transmitting plate 43 and the lower light-transmitting plate 22 is appropriate.

[0073] In some embodiments, the above image sensor 45 can adopt, for example Figure 6 the structure shown. Refer to Figure 6 , the image sensor 45 is an industrial camera.

[0074] In this embodiment, the industrial camera can be Blackfly S BFS-PGE-31S4C-C, which can be embedded in a narrow space. This industrial camera can effectively reduce glare and reflection and improve the image quality. Correspondingly, the SDK can directly adopt FLIR Spinnaker to control the parameters of the industrial camera, such as controlling the exposure, gain, and trigger mode.

[0075] In some embodiments, refer to Figures 2 to 5, the clarity detection device for pharmaceuticals controlled by an electronic computer further includes a shielding mechanism 60. The shielding mechanism 60 includes inner vertical bars 61, outer vertical bars 62, fixed cylinders 63, rotating shafts 64, light-shielding cloths 65, and a driving assembly 66. There are two inner vertical bars 61, and both of the two inner vertical bars 61 are fixedly arranged 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 sliding groove 611 with an opening facing the outer mounting cover 44. There are two outer vertical bars 62, and both of the two outer vertical bars 62 are fixedly arranged 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 sliding groove 611 with an opening facing the upper light box 42. The correspondingly arranged inner vertical sliding groove 611 and outer vertical sliding groove 621 form a sliding space. There are two fixed cylinders 63, and both of the two fixed cylinders 63 are fixedly arranged on the suspension plate 41. Each fixed cylinder 63 has a cylinder cavity, and a material feeding port communicating with the cylinder cavity is provided at the bottom end of the fixed cylinder 63. The material feeding port is correspondingly arranged with the communication port provided on the suspension plate 41. There are two rotating shafts 64, and the two rotating shafts 64 are respectively rotatably arranged in the fixed cylinders 63. There are two light-shielding cloths 65, and the two light-shielding cloths 65 respectively correspond to the two rotating shafts 64. One end of each light-shielding cloth 65 is fixedly arranged on the corresponding rotating shaft 64, and the other end enters the corresponding sliding space after passing through the material feeding port and the communication port.

[0076] Among them, the driving assembly 66 is connected to the two rotating shafts 64. When the image collection unit 40 finishes shooting and moves to the next lower light-transmitting part, it can drive each rotating shaft 64 to rotate and retract the light-shielding cloth 65 into the corresponding cylinder cavity. Or when the image collection unit 40 moves to the next lower light-transmitting part, it can drive each rotating shaft 64 to rotate and release the light-shielding cloth 65 into the corresponding sliding space.

[0077] At the inner end of the suspension plate 41, there is an upper light box 42 connected, and at the outer end, there is an outer mounting cover 44 connected. A shooting space in the form of a through-channel structure is formed between them along the sliding direction of the sliding joint part 31 of the linear driving 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 further deteriorate the detection effect. Based on this, in this embodiment, a shielding mechanism 60 is provided. The shielding mechanism 60 can block the two through-ports of the shooting space through the two light-shielding cloths 65, and then jointly with the upper light box 42 and the outer mounting cover 44, enclose the bottled pharmaceuticals to be tested therein, thereby effectively avoiding the influence of external light on the shooting of the industrial camera and ensuring the shooting effect.

[0078] However, it also involves the movement of the image collection unit 40. To avoid interference between the light-shielding cloth 65 and other bottled medicaments to be measured, two fixed cylinders 63 are provided. Both of the two fixed cylinders 63 are connected with rotating shafts 64, and the two rotating shafts 64 are respectively connected with the two light-shielding cloths 65. During the rotation of the rotating shafts 64 driven by the driving assembly 66, the light-shielding cloth 65 can be wound into the cylinder cavity, so that both ends of the shooting space are opened, ensuring that the bottled medicaments to be measured move relatively into the shooting space. One side of the light-shielding cloth 65 can be accommodated in the inner vertical chute 611 of each inner vertical strip 61, and the other side of the light-shielding cloth 65 can be accommodated in the outer vertical chute 621 of each outer vertical strip 62, so as to ensure that the light-shielding cloth 65 can be completely sealed. The corresponding inner vertical chute 611 and outer vertical chute 621 will form a sliding space to ensure the guiding of the light-shielding cloth 65 during the lifting process.

[0079] In some embodiments, the above-mentioned driving assembly 66 can adopt the structure as Figure 1 and Figure 4 shown. Refer to Figure 1 and Figure 4 . The driving assembly 66 includes a back plate 661, a column 662, a gravity block 663, a winding cylinder 664 and a flexible rope 665. The back plate 661 is fixedly arranged on the inner wall of the accommodating cavity 11 and is arranged along the driving direction of the linear driving structure 30. The back plate 661 is provided with a plurality of sequentially connected limiting surfaces, and each limiting surface corresponds to each interval 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 inclined surfaces 668 located on both sides of the lower plane 667 and connected to the two upper planes 666. The column 662 is arranged vertically and is fixedly connected with the upper light box 42. The column 662 has a guiding groove penetrating along the vertical direction and a vertical sliding opening communicated with the guiding groove. The gravity block 663 is slidably arranged in the guiding groove and has a limiting wheel that can extend out of the vertical sliding opening and be in rolling connection with the limiting surface. There are two winding cylinders 664, and both of the two winding cylinders 664 are coaxially connected with the two rotating shafts 64. There are two flexible ropes 665, and each flexible rope 665 corresponds to each winding cylinder 664 respectively. One end of each flexible rope 665 is connected to the winding cylinder 664, and the other end is connected to the gravity block 663 after passing through the wire guiding column arranged on the hanging plate 41.

[0080] First, an interval area is formed between any two adjacent lower light-transmitting parts. Each interval area corresponds to a limiting surface, and each limiting surface is smoothly connected through the upper plane 666. Each limiting surface further 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 continuously maintain contact with the limiting surface during the movement of the image acquisition unit. Therefore, during the shooting process, when the light-shielding cloth 65 is located in the sliding space, at this time, the limiting wheel on the gravity block 663 contacts 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 continuously move downward, thereby pulling the flexible rope 665. The flexible rope 665 wound around the winding cylinder 664 pulls the rotating shaft 64 to rotate, realizing the winding of the light-shielding cloth 65 and avoiding interference and collision with the bottled medicine on the lower light-transmitting part that has been detected. When the gravity block 663 enters another inclined plane 668 after passing through the lower plane 667, at this time, the gravity block 663 will pass through the second inclined plane 668. At this time, the gravity block 663 will continuously move upward, and the light-shielding cloth 65 will unwind on the rotating shaft 64 under the action of its own gravity. Subsequently, the light-shielding cloth 65 gradually slides into the sliding space to seal the shooting space, and the flexible rope 665 will be wound around the winding cylinder 664.

[0081] The setting of the driving component 66 can adjust the lifting of the light-shielding cloth 65 according to the movement of the image acquisition unit, without external power, with strong linkage, and can effectively avoid the interference between the light-shielding cloth 65 and the bottled medicine to be measured.

[0082] In some embodiments, the above light-shielding cloth 65 can adopt structures such as Figure 4 and Figure 5 as shown. Refer to Figure 4 and Figure 5 , and a gravity column 67 is provided at each end of each light-shielding cloth 65. The weight of the gravity column 67 is equal to the weight of the gravity block 663.

[0083] The gravity column 67 is horizontally arranged and arranged between the corresponding inner vertical strip 61 and outer vertical strip 62. The gravity column 67 can increase the gravity of the light-shielding cloth 65, ensure that the light-shielding cloth 65 can be flattened, and improve the flexibility of the unwinding process of the light-shielding cloth 65.

[0084] It should be noted that flexible rubber strips can be provided on both sides of each light-shielding cloth 65, which are respectively located in the inner vertical sliding groove 611 and the outer vertical sliding groove 621 to prevent the light-shielding cloth 65 from detaching from the inner vertical strip 61 or the outer vertical strip 62.

[0085] In some embodiments, the above lower light-transmitting part can adopt structures such as Figure 1The structure shown. Refer to Figure 1 , on both sides of each lower light-transmitting part, there are sponge pads 50 respectively corresponding to two light-shielding cloths 65. The sponge pads 50 can prevent the gravity column 67 from making hard contact with the lower light box 20. At the same time, the sponge pads 50 have a certain elasticity and can form depressions under the pressure of the gravity column 67, ensuring the sealing effect between the two and thus ensuring the light-shielding effect. The sponge pads 50 are black sponges.

[0086] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
