Therefore, during the production process, the oral liquid medicine bottles need to be detected. High-resolution cameras can quickly capture images of the medicine samples, and artificial intelligence algorithms can identify possible foreign matter. However, the existing detection devices mainly detect the bottom of the oral liquid medicine bottle. However, there is a possibility of residual foreign matter during the assembly of the oral liquid medicine bottle end cap. These foreign matter attached to the end cap or the inner wall of the oral liquid medicine bottle may not sink to the bottom of the oral liquid medicine bottle. If only the bottom of the oral liquid medicine bottle is detected, the detection effect is poor. Therefore, it is necessary to improve the existing detection device to enable it to detect the oral liquid medicine bottle in all directions. SUMMARY

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0021] In this paper, the "embodiment" means that the specific features, structures or characteristics described in conjunction with the embodiment can be contained in at least one embodiment of the application. The phrase appears at various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is not mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0022] Please refer to Figures 1-5The utility model discloses an embodiment of a kind of intelligent medicine foreign matter detection devices, including the first conveyor belt 1 and second conveyor belt 2 for transporting oral liquid medicine bottle, first conveyor belt 1 and second transmission belt are parallel and interval arrangement, the transport direction of first conveyor belt 1 and second conveyor belt 2 is opposite, first conveyor belt 1 and second conveyor belt 2 each have corresponding feed end and discharge end, and the feed end of first conveyor belt 1 and the feed end of second conveyor belt 2 between being equipped with multi-axis mechanical arm 3, since first conveyor belt 1 and second transmission belt between reserving interval, therefore, multi-axis mechanical arm 3 can be set between first conveyor belt 1 and second transmission belt, multi-axis mechanical arm 3 is rotatably connected with clamping part 31, clamping part 31 is used to grab and overturn oral liquid medicine bottle, clamping part 31 includes claw type holder, specifically, multi-axis mechanical arm 3 can lift clamping part 31 and rotate to the discharge end of first conveyor belt 1 above, after clamping part 31 grabs oral liquid medicine bottle, multi-axis mechanical arm 3 is rotated to the feed end of second conveyor belt 2 above, in the process of rotation of multi-axis mechanical arm 3, clamping part 31 overturns oral liquid medicine bottle simultaneously, clamping part 31 overturns oral liquid medicine bottle to be completed before multi-axis mechanical arm 3 reaches the feed end of second conveyor belt 2 above, finally by multi-axis mechanical arm 3 drive clamping part 31 and the oral liquid medicine bottle of clamping part 31 clamping drop until oral liquid medicine bottle is placed on the feed end of second conveyor belt 2.
[0023] To ensure better detection effect, first camera 4 is arranged on the side of the discharge end of first conveyor belt 1, and second camera 5 is arranged on the side of the discharge end of second conveyor belt 2, wherein the first camera 4 and the second camera 5 are high-resolution cameras. Regarding the installation positions of the first camera 4 and the second camera 5, it can be understood that the glass slag or metal fragments remaining in the oral liquid medicine bottle have a relatively large density, especially the metal fragments, which have a higher specific gravity, much larger than the density of the liquid (the density of the oral liquid is usually low). According to the principle of buoyancy, heavier substances will naturally settle at the bottom. After the oral liquid medicine bottle is placed on the feed end of the first conveyor belt 1, it will be transported to the discharge end of the first conveyor belt 1 after a period of time. During this period, the oral liquid medicine bottle is equivalent to being parked and stationary (or relatively stationary). During the parking or storage of the oral liquid medicine bottle, the flow of the liquid stops, which causes the heavier fragments such as glass slag or metal fragments to deposit at the bottom of the oral liquid medicine bottle. Therefore, the detection result obtained by using the first camera 4 to shoot and detect the bottom of the oral liquid medicine bottle is more accurate.
[0024] After the oral liquid medicine bottle is flipped by the clamping part 31 and placed at the feeding end of the second conveying belt 2, after a period of time, the oral liquid medicine bottle will be conveyed to the discharging end of the second conveying belt 2, and the oral liquid medicine bottle will be parked or stored on the second conveying belt 2 for a period of time, and then the second camera 5 is used to shoot and detect the top (which is flipped at this time) of the oral liquid medicine bottle, and the detection result obtained is more accurate.
[0025] In addition, in the process of producing the oral liquid medicine bottle, sealing detection is a very important link, and the sealing directly relates to the quality, stability and safety of the medicine, so strict detection is required. Through strict sealing detection, leakage, pollution and deterioration of the medicine can be effectively prevented, and it is ensured that the medicine can be safely and effectively delivered to the hands of consumers. In modern medicine production, this link is an indispensable quality control part, therefore, a separate device for detecting the sealing of the oral liquid medicine bottle is usually required for the production line, and the production line may need additional space to place the device, which will increase the complexity of the factory layout and the challenge of space utilization, and will increase the production cost. To this end, the utility model also provides some embodiments, in particular:
[0026] The first conveying belt 1 is provided with a plurality of first grooves 11 arranged at intervals, the first grooves 11 are filled with a first sponge layer 6 and a first humidity sensor 8 for detecting the humidity of the first sponge layer 6, the second conveying belt 2 is connected with a partition plate 22 arranged at intervals with the second conveying belt 2, the second conveying belt 2 is provided with a plurality of second grooves 21 arranged at intervals, the second grooves 21 are filled with a second sponge layer 7 and a second humidity sensor 9 for detecting the humidity of the second sponge layer 7, and the partition plate 22 is provided with a corresponding hole 221 above each second groove 21. By designing the first grooves 11 and the second grooves 21 and filling the grooves with sponges specially for carrying the oral liquid medicine bottles, once the oral liquid medicine bottles leak, the corresponding first humidity sensor 8 or second humidity sensor 9 can detect the change in humidity of the first sponge layer 6 or second sponge layer 7 due to the absorption of the leaked liquid from the oral liquid medicine bottles, so that the leaking oral liquid medicine bottles can be found in time, and the sealing detection of the oral liquid medicine bottles can be realized. As for the partition plate 22 and the holes 221 on the partition plate 22, it can be understood that the top of most oral liquid medicine bottles will gradually narrow, therefore, an auxiliary fixing mechanism needs to be designed to ensure that the oral liquid medicine bottles will not easily fall during transportation. Of course, an auxiliary fixing mechanism similar to the partition plate 22 can also be provided on the first conveying belt 1. Preferably, the holes 221 are circular and gradually shrink from top to bottom, so that the holes 221 can match the oral liquid medicine bottles with gradually narrowing tops. Generally, the first grooves 11 and the second grooves 21 are circular, and the area of the first grooves 11 is larger than that of the second grooves 21.
[0027] In addition, a conveying mechanism for feeding or discharging is arranged between the feeding end of the first conveying belt 1 and the discharging end of the second conveying belt 2, which is equivalent to the multi-axis mechanical arm 3 and the clamping part 31 connected to the multi-axis mechanical arm 3, and the first conveying belt 1, the second conveying belt 2, the multi-axis mechanical arm 3, the clamping part 31, the first camera 4, the second camera 5, the first humidity sensor 8, the second humidity sensor 9 and the conveying mechanism and other related mechanisms can be connected to the corresponding control system or control center for convenient control and detection.
