[0023] The technical solution provided by the embodiments of the present application is described below in conjunction with the accompanying drawings.

[0024] In one embodiment, if Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the present application provides an automatic extension mechanism for a medicine taking hopper, comprising a guide rail bracket 1, a medicine discarding plate 3 is slidably connected inside the guide rail bracket 1, a medicine taking hopper 2 is slidably connected to the top surface of the guide rail bracket 1, a linear slide rail 12 provided for sliding of the medicine taking hopper 2 is fixedly installed on the top surface of the guide rail bracket 1, a linear slider 13 is fixedly installed on the bottom surface of the medicine taking hopper 2, the linear slider 13 is slidably connected to the linear slide rail 12, a medicine taking drive assembly 8 for taking out medicines is arranged on the top surface of the guide rail bracket 1, the medicine taking drive assembly 8 comprises a medicine taking bracket 17, a first DC reduction motor 18, a first driving wheel 19, a first driven wheel 22 and a first synchronous belt 25, a medicine discarding drive assembly 9 for discarding medicines is arranged on the top surface of the guide rail bracket 1, and the medicine discarding drive assembly 9 comprises a medicine discarding bracket 26, a second DC reduction motor 27, a second driven wheel 28 and a second driving wheel 29;

[0025] Furthermore, the medicine taking bracket 17 is installed on the top surface of the guide rail bracket 1, and a connecting block 24 is fixedly installed on the bottom surface of the medicine taking bracket 17. A hole is opened on the top surface of the connecting block 24. The staff puts the bolts into the holes on the connecting block 24, thereby installing the medicine taking bracket 17 on the top surface of the guide rail bracket 1. One side of the medicine taking bracket 17 is rotatably connected to the first driving wheel 19, and one side of the medicine taking bracket 17 is fixedly installed with a first DC reduction motor 18 for driving the first driving wheel 19 to rotate. The output shaft of the first DC reduction motor 18 passes through the medicine taking bracket 17 and is connected to one end of the first driving wheel 19. One side of the medicine taking bracket 17 is rotatably connected to two first driven wheels 22 through a bearing. One end of the first driven wheel 22 is fastened by a hexagon socket screw, and a first synchronous belt 25 is wound around the outer circumferential wall of the first driving wheel 19 and the two first driven wheels 22. One side of the medicine dispensing bracket 17 is rotatably connected to two first tensioning wheels 20 through a bearing. The outer circumferential wall of the first tensioning wheel 20 is movably sleeved with the outer circumferential wall of the first synchronous belt 25. The first tensioning wheel 20 can squeeze the first synchronous belt 25 to tighten the first synchronous belt 25. Two flat washers 21 are fixedly installed on one side of the medicine dispensing bracket 17. The first synchronous belt 25 is connected to the medicine dispensing hopper 2. A support plate 4 is fixedly installed on the top surface of the medicine dispensing hopper 2. An identification member for identifying medicines is provided on one side of the support plate 4.

[0026] The identification member includes a camera 14, which is rotatably connected to one side of the support plate 4 through a bearing. The camera 14 is driven by a common driving device on the market, such as a driving motor, etc. A large number of photos of medicine boxes are input into the database in advance, and the photos taken by the camera 14 are compared with the photos in the database. The camera 14 performs image recognition on the medicines that fall into the medicine hopper, thereby reducing the probability of taking the wrong medicine. A beam grating 16 is fixedly installed on one side of the medicine discarding plate 3;

[0027] By setting the medicine taking hopper 2, when medicine falls into the medicine taking hopper 2, the reflected grating 16 receives the signal, triggering the camera 14 to identify whether the medicine in the hopper is correct. When the medicine is correct, the output shaft of the first DC reduction motor 18 on the medicine taking bracket 17 rotates to drive the first driving wheel 19 to rotate. The first driving wheel 19 rotates to drive the two first driven wheels 22 to rotate through the first synchronous belt 25. The two first tensioning wheels 20 on the medicine taking bracket 17 can increase the tension of the first synchronous belt 25. The rotation of the first synchronous belt 25 also makes the medicine taking hopper 2 on the guide rail bracket 1 extends outward, and at the same time, the medicine discarding plate 3 in the medicine discarding driving assembly 9 will also extend outward at the same time as the medicine taking bucket 2, and the medicine taking bucket 2 and the medicine discarding plate 3 extend outward to drive the medicine to move outward, and then the user can take the medicine out of the medicine taking bucket 2. If all the medicines are taken out, the medicine taking bucket 2 and the medicine discarding plate 3 will be reset to their original positions. If there are any medicines left, the machine will issue an alarm to remind the user after the corresponding grating 16 recognizes them, thereby completing the entire medicine taking process and achieving the medicine taking effect, avoiding some medicines from being left inside the medicine taking bucket 2, and facilitating the user to take out the medicines from the medicine taking bucket 2;

[0028] In another embodiment, if Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, further, the abandoned medicine bracket 26 is installed on the top surface of the guide rail bracket 1, and the bottom surface of the abandoned medicine bracket 26 is fixedly installed with a support block 23, and the top surface of the support block 23 is provided with a hole. The staff puts the bolts into the holes on the support block 23, so as to install the abandoned medicine bracket 26 on the top surface of the guide rail bracket 1, and the inside of the guide rail bracket 1 is slidably connected with an abandoned medicine hopper 5 for collecting abandoned medicines;

[0029] One side of the discarded medicine bracket 26 is rotatably connected to a second driving wheel 29, and one side of the discarded medicine bracket 26 is fixedly installed with a second DC reduction motor 27 for driving the second driving wheel 29 to rotate. The output shaft of the second DC reduction motor 27 passes through the discarded medicine bracket 26 and is fixedly connected to one end of the second driving wheel 29. One side of the discarded medicine bracket 26 is rotatably connected to two second driven wheels 28 through a bearing, and the second driven wheels 28 are locked on the discarded medicine bracket 26 through hexagon socket screws and nuts. A second synchronous belt 30 is wound around the outer circumferential wall surface of the second driving wheel 29 and the two second driven wheels 28. The second synchronous belt 30 is connected to the discarded medicine plate 3. One side of the discarded medicine bracket 26 is rotatably connected to two second belt tensioning wheels 31 for tightening the second synchronous belt 30 through a bearing, and the second belt tensioning wheel 31 is fastened to one side of the discarded medicine bracket 26 through a hexagon socket screw.

[0030] By setting the medicine taking hopper 2, when the medicine falls into the inside of the medicine taking hopper 2, the reflected grating 16 receives a signal, triggering the camera 14 to identify whether the medicine in the hopper is correct. When the medicine is wrong, the medicine taking hopper 2 will not move outward. At the same time, the output shaft of the second DC reduction motor 27 rotates to drive the second driving wheel 29 to rotate. The second driving wheel 29 rotates to drive the two second driven wheels 28 to rotate through the second synchronous belt 30. The two second belt tensioning wheels 31 on the medicine discarding bracket 26 can squeeze the second synchronous belt 30. The rotation of the second synchronous belt 30 will drive the medicine discarding plate 3 to move backward. At this time, the medicine inside the medicine taking hopper 2 will fall into the inside of the medicine discarding hopper 5, so that the wrong medicine is discarded, achieving the medicine discarding effect;

[0031] Drawer guide rails 10 for sliding the discarded medicine hopper 5 are fixedly installed on both sides of the inner side of the guide rail bracket 1. Drawer sliders 11 are fixedly installed on both sides of the discarded medicine hopper 5. The drawer sliders 11 are slidably connected with the drawer guide rails 10. Through the disposed discarded medicine hopper 5, the staff moves the discarded medicine hopper 5 outward to drive the drawer sliders 11 to slide inside the drawer guide rails 10 on the guide rail bracket 1, thereby taking out the discarded medicines inside the discarded medicine hopper 5;

[0032] A fixing block 6 is fixedly installed on both sides of the guide rail bracket 1. Two fixing holes 7 are provided on the top surface of the fixing block 6. Through the setting of the fixing block 6, the staff puts the bolts into the fixing holes 7 on the fixing block 6, thereby installing the guide rail bracket 1 in a suitable position;

[0033] An ultraviolet sterilization lamp 15 for sterilizing the medicines in the medicine hopper 2 is installed inside the support plate 4. Through the set up opposite-beam grating 16, when the opposite-beam grating 16 detects that medicines have entered the inside of the medicine hopper 2, the ultraviolet sterilization lamp 15 will be started. The ultraviolet sterilization lamp 15 can irradiate the medicines, thereby sterilizing the medicine hopper 2 and the medicines.

[0034] The working principle of the utility model is:

[0035] First, through the medicine hopper 2, when medicine falls into the medicine hopper 2, the reflected grating 16 receives a signal, triggering the camera 14 to identify whether the medicine in the hopper 2 is correct, and at the same time, the ultraviolet sterilization lamp 15 lights up to sterilize the medicine hopper 2 and the medicine;

[0036] Secondly, if the medicine is correct, the entire medicine hopper 2 together with the medicine discarding plate 3 moves forward and extends out of the machine; if the medicine is incorrect (including the wrong quantity or type of medicine), the medicine hopper 2 does not extend, and the medicine discarding drive assembly 9 drives the medicine discarding plate 3 to move backward, and the medicine falls into the medicine discarding hopper 5 below to be taken out by after-sales personnel;

[0037] Finally, under the premise that the medicines are correct, the medicine hopper 2 is extended and the user starts to take the medicines. If all the medicines are taken away, it will operate normally, and the medicine hopper 2 together with the medicine discarding plate 3 will move backwards and return to the initial position, waiting for the next time to take medicines; if there are any medicines left, the reflected light grating 16 will sense it and the machine will alarm.

[0038] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
