The intermittent material transfer mechanism 3 between the loading conveyor 2 and the intermittent feeding conveyor 2 intermittently transfers the oral solution bottles on the loading conveyor 2 to the intermittent feeding conveyor 2, and the intermittent material transfer mechanism 3 between the unloading conveyor 2 and the intermittent feeding conveyor 2 transfers the oral solution bottles after testing to the unloading conveyor 2.

[0056] Among them, Figure 7 , Figure 8 , Fig.10 , Fig.12 and Fig.13 As shown, the blower 84 is a cavity structure, on which at least one group of air injection holes distributed in a ring shape is provided. The blower 84 is also provided with four connecting bosses 841 distributed in a rectangular shape. Two of the connecting bosses 841 are provided with positioning through holes 844 for positioning the blower 84, and one end of the other two connecting bosses 841 are respectively provided with assembly holes 843 and threaded holes 842 connected to the inner cavity of the blower 84 for connecting to the gas delivery box 83.

[0057] Specifically, the fixing assembly includes a lower limit plate 857 arranged on one side of the mounting bracket 85, a plurality of lower support plates 851 arranged on the other side of the mounting bracket 85, and an upper pressure plate 854 arranged above the lower support plate 851.

A movable rod 856 is provided on the top of the upper pressure plate 854. The outer sleeve of the movable rod 856 is provided with a connecting spring 855 for connecting the upper pressure plate 854 and the mounting bracket 85. A limit slide groove 853 slidably matched with the crimping part is provided on the mounting bracket 85, and a sliding through hole slidably matched with the movable rod 856 is also provided on the top plate of the mounting bracket 85.

[0058] Lift up the movable rod 856 to drive the upper pressure plate 854 to cooperate with the mounting bracket 85 to compress the connecting spring 855, and utilize the plug-in cooperation between the positioning column 852 and the positioning through hole 844 to assemble the blower 84 on one side of the mounting bracket 85. Then, remove the force of lifting the movable rod 856, and the upper pressure plate 854 presses the blower 84 under the elastic force of the connecting spring 855, completing the quick connection between the blower 84 and the mounting bracket 85, which is convenient for the later replacement of the blower 84.

[0059] Specifically, the driving assembly consists of a linear module 81 installed on the top of the bottom plate of the supporting frame 1 and a lifter 82 installed on the top of the moving body of the linear module 81. The piston end of the lifter 82 is provided with a connecting plate for connecting with the mounting bracket 85. The mounting bracket 85 is driven by the linear module 81 to bring the purge 84 to the bottom of the oral solution bottle. The purge 84 is driven up and down by the lifter 82 to change the height of the purge 84 and increase the purge range.

[0060] Among them, Figure 8 , Fig. 9 and Fig.11 As shown, one side of the gas delivery box 83 is provided with an assembly body 831 matching the assembly hole 843, and the bottom ventilation interface is connected to a control valve 833, both ends of which are provided with fixing parts 832, one side of the fixing part 832 is screwed with a clamping bolt, and the L-shaped connecting part 87 is provided with a strip through hole 871 that can cooperate with the clamping bolt; the control valve 833 is connected to the gas supply equipment using a pipeline. After the gas supply equipment is running and the control valve 833 is opened, the gas will flow from the gas delivery box 83 to the connecting rod 86, and finally be ejected through the jet hole on the purge device 84 and blown to the oral solution bottle for purging; the plug-in cooperation of the assembly body 831 and the assembly hole 843 is used to facilitate the alignment of the screw pipe 863 with the threaded hole 842.

[0061] After unscrewing the threaded tube 863 of the connecting rod 86 from the threaded hole 842, loosen the clamping bolt 1 so that the clamping bolt 1 can move in the strip through hole 1 871 to change the position and angle of the gas box 83, thereby facilitating the replacement of the purge device 84. During the replacement of the purge device 84, there is no need to remove the gas box 83, which can save time and effectively reduce the probability of losing accessories such as the clamping bolt 1 and the gas box 83.

[0062] Among them, Fig.11 As shown, the connecting rod 86 is composed of a screw body 861 screwed to the gas delivery box 83, a screw pipe 863 screwed to the gas delivery box 83, and an arcuate connecting portion 862 for connecting the screw body 861 and the screw pipe 863. The screw pipe 863 is also threadedly connected to the threaded hole 842. The arcuate connecting portion 862 is arranged between the screw body 861 and the screw pipe 863. The arranged arcuate connecting portion 862 can not only connect the screw body 861 and the screw pipe 863, but also cooperate with the screw pipe 863 to connect the gas delivery box 83 and the purge device 84.

[0063] Among them, Figure 3-5 As shown, one side of the supporting turntable 52 is provided with a rotating column 522 arranged in a ring distribution manner, and the rotating column 522 is slidably matched with the ring track 51. One side of the supporting turntable 52 is also symmetrically provided with a threaded sleeve 521, and the connecting assembly includes a connecting rod 1 56 threadedly connected to the threaded sleeve 521, a connecting rod 2 55 connected to the central rotating shaft 54 ​​via a nut, and a clamping bolt 2 58 that can be threadedly connected to the connecting rod 2 55. One end of the connecting rod 1 56 is connected to a matching piece 57 via a connecting bolt, and the matching piece 57 is provided with a strip through hole 2 571 that cooperates with the clamping bolt 2 58.

[0064] The connecting rod 1 56 is fixed by screwing it with the threaded sleeve 521. After the connecting rod 2 55 is passed through the through hole on the central rotating shaft 54, the nut is tightened to complete the installation of the connecting rod 2 55. Then, the connecting bolt is loosened and the position of the matching piece 57 is adjusted to make the strip through hole 2 571 coincide with the threaded blind hole on the connecting rod 2 55. After the clamping bolt 2 58 is inserted into the threaded blind hole from the strip through hole 2 571, the clamping bolt 2 58 and the connecting bolt are tightened to complete the connection between the supporting turntable 52 and the central rotating shaft 54. The existence of the matching piece 57 is suitable for connecting connecting rods 2 55 of different lengths, thereby reducing the difficulty of installation and saving installation time.

[0065] Specifically, the support turntable 52 is provided with a plurality of avoidance openings for avoiding the oral solution bottles, so as to facilitate the conveyor 2 to transport the oral solution bottles.

[0066] Specifically, a through hole capable of accommodating the second connecting rod 55 to pass through is formed on the central rotating shaft 54 ​​and is used for installing the second connecting rod 55 . A threaded blind hole capable of being threadedly connected with the second clamping bolt 58 is formed on the second connecting rod 55 .

[0067] Among them, as Figure 3 , Figure 4 and Figure 6 shown, the clamping mechanism 7 includes two connecting brackets 71 arranged face to face, two clamping members 72 arranged between the connecting brackets 71, and a cam 73 arranged between the two clamping members 72. A clamping motor 76 for driving the cam 73 is installed on one side of one of the connecting brackets 71. A driver 77 is arranged on one side of the clamping motor 76. The piston rod of the driver 77 is connected to the corresponding connecting bracket 71. A U-shaped rod one 74 and a U-shaped rod two 78 are arranged on one side of the connecting bracket 71. And the clamping member 72 is movably connected to the U-shaped rod two 78 through a movable component 75. The driver 77 can be a telescopic component such as an electric telescopic cylinder or a pneumatic telescopic cylinder.

[0068] The cam 73 is driven by the clamping motor 76. At the same time, with the help of the movable component 75, the distance between the two clamping members 72 is adjusted. The clamping operation of the oral solution bottle is completed by using the two clamping members 72 that approach each other. Then, the driver 77 is used to drive the connecting bracket 71 to rise, so that the oral solution bottle leaves the middle conveyor 2, which not only facilitates the subsequent purging work, but also is beneficial to the flipping of the oral solution bottle.

[0069] Specifically, the clamping mechanism 7 further includes a support rod 79 for connecting the two connecting brackets 71 and a bearing plate for supporting the driver 77. The bearing plate is installed on one of the support turntables 52, and the bearing plate plays a role in supporting the driver 77.

[0070] Specifically, the movable component 75 includes two connecting ears respectively connected to the U-shaped rod two 78 and the clamping member 72 and a guide rod. One end of the guide rod is fixedly connected to the connecting ear on the U-shaped rod two 78, and a sliding hole slidably matched with the guide rod is opened on the connecting ear connected to the clamping member 72. A buffer spring connected to the connecting ear is also sleeved outside the guide rod. The buffer spring can make the clamping member 72 always抵触 the surface of the cam 73, which is beneficial to the clamping member 72 clamping the oral solution bottle.

[0071] Specifically, a guide chute is opened on one side of the U-shaped rod one 74. A slider slidably matched with the guide chute is arranged on the clamping member 72. By using the sliding fit of the slider and the guide chute for guiding, the deviation of the moving direction of the clamping member 72 can be effectively avoided; an arc-shaped groove 721 convenient for clamping the bottleneck of the oral solution bottle is opened on the clamping member 72.

[0072] Among them, as Figure 1 and Figure 2As shown, the visual inspection mechanism 6 includes a detection bracket 62 connected to the supporting stand 1, a rotator 63 installed on one side of the detection bracket 62, and a visual detector 61 connected to the rotating axis of the rotator 63 via the rotating bracket. The rotating bracket is connected to the rotating axis of the rotator 63, and the visual detector 61 is installed on the rotating bracket. A fill light 64 is provided on one side of the visual detector 61. The fill light 64 is used to fill in the light, and image information is collected through the visual detector 61 to realize foreign body inspection; the rotator 63 can change the position of the visual detector 61, which can effectively avoid the collision between the visual detector 61 and the oral solution bottle.

[0073] Among them, Figure 1 and Figure 2 As shown, the lamp tube 4 is provided with a plurality of detection lamps 41 in a circular distribution manner, and both ends of the lamp tube 4 are symmetrically provided with L-shaped support members connected to the bottom plate of the support stand 1, and the detection lamps 41 are used to illuminate the oral solution bottle.

[0074] An automatic inspection method for foreign matter in oral solution includes the above-mentioned automatic inspection device for foreign matter in oral solution, and the specific steps are as follows:

[0075] Step 1: Loading, transporting the oral solution bottles to the foreign matter inspection area through the conveyor 2 and the intermittent feeding mechanism 3;

[0076] Step 2: Blowing, after the clamping mechanism 7 clamps the oral solution bottle and takes the oral solution bottle away from the middle conveyor 2, the blowing mechanism 8 blows the bottle body to remove foreign matter on the surface of the bottle body;

[0077] Step 3: Inspection: the bottle is turned over by the rotating mechanism 5, and the oral solution is inspected from all directions by the visual inspection mechanism 6 arranged at different positions;

[0078] Step 4: unloading, using the rotating mechanism 5 and the clamping mechanism 7 in cooperation, placing the tested oral solution bottles on the middle conveyor 2, and using the conveyor 2 to take the oral solution bottles away from the foreign matter inspection area.

[0079] During operation, the oral solution bottle is transported to the foreign body inspection area through the conveyor 2 and the intermittent feeding mechanism 3, and the cam 73 is driven by the clamping motor 76 to cooperate with the movable component 75 to drive the clamping member 72 to clamp the oral solution bottle, and then the driver 77 is used to drive the connecting bracket 71 to rise, so that the oral solution bottle leaves the middle conveyor 2, and the installation bracket 85 is driven by the linear module 81 to bring the purge device 84 under the oral solution bottle. After the gas supply equipment is running and the control valve 833 is opened, the gas will flow from the gas delivery box 83 to the connecting rod 86, and finally be ejected through the jet hole on the purge device 84 and blown to the oral solution bottle for purging. The purge device 84 is driven to rise and fall by the lifter 82 to change the height of the purge device 84, so that the purging range becomes larger, which can effectively clear the bottle body. After the foreign matter on the surface is purged, the control motor 53 drives the central shaft 54, and then drives the supporting turntable 52 and the clamping mechanism 7 to turn the bottle over, and then the visual inspection mechanism 6 arranged at different positions is used to collect image information of the bottle in different postures to improve the accuracy of foreign matter detection of oral solution. For foreign matter firmly adhered to the surface of the oral solution bottle, it is also possible to determine whether the position of the foreign matter remains unchanged by comparing the bottle in different postures (the position of the foreign matter inside will change with the different postures of the bottle), and then determine whether it is a foreign matter in the bottle, so as to reduce the probability of false detection. After the detection is completed, the rotating mechanism 5 and the clamping mechanism 7 are used in combination to put the tested oral solution bottle on the middle conveyor 2, and the conveyor 2 is used to take the oral solution bottle away from the foreign matter inspection area.
