Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a desktop medication dispensing structure. Background Technology

[0002] In medical settings, it is common for doctors to retrieve medication from a dispensing window. Existing dispensing mechanisms often suffer from problems such as the inconvenient placement of the medicine box, making it difficult for doctors to retrieve and impacting work efficiency. In existing mechanisms, the pull plate and the baffle are fixed together on a sliding block. Due to the baffle's restriction, the pull plate cannot reach the exit, requiring doctors to reach deep into the dispensing window to retrieve the medication, which is inconvenient.

[0003] In addition, traditional structures are also lacking in terms of operational stability and structural compactness, and cannot meet the needs of efficient and convenient medical work. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the position of the medicine box is not conducive to doctors' access, and to propose a desktop medicine dispensing structure that makes the medicine box closer to the outlet when it is pushed out, making it easier for doctors to access the medicine box, while improving the stability and reliability of the structure's operation.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A desktop medicine dispensing structure includes a fixed plate, a synchronous belt drive mechanism, a guide rail, a first slider, and a medicine-pulling plate. The synchronous belt drive mechanism and the guide rail are mounted on the fixed plate. The first slider is fixedly connected to the synchronous belt and slidably engaged with the guide rail. The medicine-pulling plate is fixed on the first slider and is perpendicular to the fixed plate. The structure also includes a second slider, a third slider, and a medicine-blocking plate. The second and third sliders are slidably engaged with the guide rail. The first slider is located between the second and third sliders and is movably connected to them. The two ends of the medicine-blocking plate are respectively fixed on the second and third sliders and are parallel to the fixed plate. The medicine-blocking plate and the medicine-pulling plate together form a medicine box pushing space.

[0007] Furthermore, the first slider and the third slider are connected by a magnet.

[0008] Furthermore, the synchronous belt drive mechanism includes a stepper motor, a drive wheel, a driven wheel, and a synchronous belt. The stepper motor, drive wheel, and driven wheel are mounted on a fixed plate. The drive wheel is connected to the output shaft of the stepper motor, and the drive wheel and driven wheel are connected by a synchronous belt drive.

[0009] Furthermore, it also includes an origin baffle and an origin signal sensor. The origin baffle is fixed below the first slider, and the origin signal sensor is fixed on a fixed plate. The origin signal sensor is located at the end position of the movement path of the first slider.

[0010] Furthermore, it also includes a driven wheel bearing housing, a driven wheel adjusting block, and bolts. The fixed plate has an elongated hole. The driven wheel and the driven wheel bearing housing are respectively installed on both sides of the fixed plate. The driven wheel is connected to the driven wheel bearing housing through the elongated hole. The driven wheel adjusting block is installed on the fixed plate and located on the side of the driven wheel bearing housing closer to the drive wheel. The driven wheel adjusting block has a through hole along the length of the fixed plate. The bolt passes through the through hole and contacts the side of the driven wheel bearing housing.

[0011] Furthermore, it also includes a medicine-pulling plate fixing block, a first medicine-blocking plate fixing block, and a second medicine-blocking plate fixing block. The medicine-pulling plate fixing block is fixed on the first slider, and the medicine-pulling plate is fixed on the first slider through the medicine-pulling plate fixing block. The origin baffle is fixed at the lower end of the medicine-pulling plate fixing block.

The medicine-blocking plate is fixed on the second slider and the third slider through the first medicine-blocking plate fixing block and the second medicine-blocking plate fixing block.

[0012] Furthermore, a belt pressure plate is provided on the drug-pulling plate fixing block, and the timing belt is disposed between the belt pressure plate and the drug-pulling plate fixing block.

[0013] Furthermore, it also includes a backing block, which is fixed to the fixing plate and located at both ends of the guide rail.

[0014] Furthermore, the origin signal sensor is a proximity sensor.

[0015] Compared with the prior art, the significant advantages of this utility model are: (1) By setting a stepper motor to drive the synchronous belt and slider to move, the medicine-pulling plate is driven to push the medicine box out, which makes the medicine box closer to the exit position, greatly facilitating the doctor to take the medicine box and improving the efficiency of taking medicine; (2) By cooperating with the guide rail and the slider and the reasonable setting of each component in the synchronous belt transmission system, the stability of the whole structure during operation is guaranteed, and shaking and deviation are reduced; (3) By setting the origin baffle and the origin signal sensor, the initial position of the slider can be accurately determined, and precise positioning can be achieved to ensure that the position of the medicine box pushed out each time is accurate and consistent; (4) By setting the driven wheel tensioning block and the belt pressure plate, the tension of the synchronous belt can be easily adjusted and the synchronous belt can be prevented from deviating during the transmission process, ensuring the reliability of the transmission.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] This utility model provides a desktop medicine dispensing structure, such as Figures 1-3 As shown, it includes: a fixed plate 4, a stepper motor 1 (a 42-stepper motor is used in this embodiment), a drive wheel 2, a driven wheel 9, a synchronous belt 5, a guide rail 15, a first slider 6, a medicine-pulling plate 11, a second slider 13, a third slider 20, a medicine-blocking plate 12, a medicine-pulling plate fixing block 10, a first medicine-blocking plate fixing block 3, and a second medicine-blocking plate fixing block 23.

[0023] Stepper motor 1, drive wheel 2, driven wheel 9, and guide rail 15 are mounted on fixed plate 4. Drive wheel 2 is connected to the output shaft of stepper motor 1, and drive wheel 2 and driven wheel 9 are connected by synchronous belt 5. Stepper motor 1 is used to provide power to the drug delivery section.

[0024] The first slider 6 is fixedly connected to the lower side of the synchronous belt 5. The first slider 6, the second slider 13, and the third slider 20 are slidably engaged with the guide rail 15. The first slider 6 is located between the second slider 13 and the third slider 20. The first slider 6 and the third slider 20 are movably connected by a magnet. Specifically, a magnet is embedded in the third slider 20. When the magnet comes into contact with the first slider 6, it attracts the first slider 6.

[0025] The medicine-pulling plate fixing block 10 is fixed to the first slider 6. The medicine-pulling plate 11 is fixed to the first slider 6 via the medicine-pulling plate fixing block 10. The first medicine-blocking plate fixing block 3 is fixed to the second slider 13. The second medicine-blocking plate fixing block 23 is fixed to the third slider 20. Both ends of the medicine-blocking plate 12 are fixed to the second slider 13 and the third slider 20 via the first medicine-blocking plate fixing block 3 and the second medicine-blocking plate fixing block 23. The medicine-pulling plate 11 is perpendicular to the fixing plate 4, and the medicine-blocking plate 12 is parallel to the fixing plate 4. The medicine-blocking plate 12 is U-shaped. The first slider 6 and the medicine-pulling plate fixing block 10 are located above the concave part of the medicine-blocking plate 12. The upper part of the medicine-pulling plate 11 is used to connect with the medicine-pulling plate fixing block 10, and the lower part of the medicine-pulling plate 11 is used to push the medicine towards the outlet. The medicine-pulling plate 11 and the medicine-blocking plate 12 are close to but do not contact each other. The medicine-blocking plate and the medicine-pulling plate constitute the medicine box pushing space, and the medicine box 22 is located within the medicine box pushing space.

[0026] To accurately determine the termination position of each medication dispensing process, this embodiment also includes an origin baffle 18 and an origin signal sensor 19. The origin baffle 18 is fixed to the lower end of the medication dispensing plate fixing block 10. The origin signal sensor 19 is fixedly mounted on the fixing plate 4 via a signal bracket 21 at the termination position of medication dispensing, i.e., the termination position of the movement path of the first slider 6. The origin signal sensor 19 cooperates with the origin baffle 18 to limit the stepper motor 1 from going beyond its limit, ensuring that the termination position of each medication dispensing action is consistent and improving the accuracy of medication dispensing. The origin signal sensor 19 is a proximity sensor. When the origin baffle 18 is in front of the origin signal sensor 19, the origin signal sensor 19 controls the stepper motor 1 to switch on and off via a relay.

[0027] This embodiment also includes a driven wheel bearing housing 7, a driven wheel adjusting block 17, and a bolt 24. An elongated hole is provided on the fixing plate 4. The driven wheel 9 and the driven wheel bearing housing 7 are respectively installed on both sides of the fixing plate 4. The driven wheel 9 is connected to the driven wheel bearing housing 7 through the elongated hole. The driven wheel adjusting block 17 is installed on the fixing plate 4, located on the side of the driven wheel bearing housing 7 closest to the drive wheel 2. The driven wheel adjusting block 17 has a through hole along the length of the fixing plate 4. The bolt 24 passes through the through hole and contacts the side of the driven wheel bearing housing 7. By rotating the bolt 24, the driven wheel bearing housing 7 is pushed, causing the driven wheel bearing housing 7 and the driven wheel 9 to move along the elongated hole, thereby adjusting the tension of the synchronous belt 5 and ensuring that the synchronous belt 5 maintains appropriate tension throughout the transmission process.

[0028] A belt pressure plate 8 is provided on the drug-pulling plate fixing block 10, and a timing belt 5 is disposed between the belt pressure plate 8 and the drug-pulling plate fixing block 10. The belt pressure plate 8 is used to fix the timing belt 5 to prevent it from shifting during transmission, thereby further ensuring the stability of transmission.

[0029] In this embodiment, the fixed plate 4 is also provided with two support blocks 16, located at both ends of the guide rail. On the one hand, they prevent the slider from exceeding the limit, such as due to damage to the origin signal sensor 19 or other reasons causing the slider speed to be too fast or the braking to be untimely. On the other hand, the support blocks 16 at the termination position help the first slider 6 to disengage from the third slider 20.

[0030] In application, the fixing plate 4 is fixed to the column 14 on the desktop, so that the desktop medicine dispensing structure is at a suitable height.

[0031] The forward and reverse rotation of the 42-stepper motor 1 drives the drive wheel 2 to rotate. The drive wheel 2 drives the driven wheel 9 to rotate via the synchronous belt 5. The synchronous belt 5 drives the first slider 6 connected to it to move back and forth along the guide rail 15. The first slider 6 and the third slider 20 are attracted to each other. The first slider 6 drives the second slider 13 and the third slider 20 to slide along the guide rail 15. This provides power for the medicine box 22 to be pushed out and retracted by the medicine plate 11.

[0032] The first slider 6 and the third slider 20 are in their initial positions. The medicine box 22 is conveyed from the receiving side of the conveyor belt to the front of the medicine-pulling plate 11. The medicine-blocking plate 12 prevents the medicine box 22 from moving outside the medicine box pushing space. The first slider 6, connected to the synchronous belt 5, moves linearly along the guide rail 15 under the guidance of the guide rail 15. The second slider 13 and the third slider 20 move simultaneously along the guide rail 15 under the drive of the first slider 6. During the movement of the first slider 6, the second slider 13, and the third slider 20, the medicine-pulling plate fixing block 10 drives the medicine-pulling plate 11 to move synchronously. The medicine-pulling plate 11 pushes the medicine box 22 towards the outlet direction. The medicine-blocking plate 12 also acts as a blocking function to prevent the medicine box 22 from moving randomly during the push-out process, ensuring that the medicine box 22 can be accurately pushed when taking medicine.

[0033] When the second slider 13 contacts the backing block 16, the first slider 6 continues to move with the synchronous belt 5, and the first slider 6 disengages from the third slider 20, and the medicine baffle 12 stops moving. When the first slider 6 moves to the origin signal sensor 19, the first slider 6 stops moving. At this time, the medicine pull plate 11 pushes the medicine box 22 to a position close to the outlet for easy retrieval.

[0034] Afterward, the tabletop medicine dispensing structure returns to its original position. The first slider 6 moves in the opposite direction with the synchronous belt 5, and after contacting the third slider 20, they attract each other, causing the medicine baffle plate 12 to move together to the initial position. By precisely controlling the number of pulses of the stepper motor 1, the stepper motor 1 stops rotating after the third slider 20 returns to the initial position, thus allowing the first slider 6 and the third slider 20 to stop precisely at the initial position.

[0035] This invention features a belt drive system and a drug delivery system. The belt drive system uses a 42-stepper motor as its core power source, with the drive wheel 2, synchronous belt 5, and driven wheel 9 working together to achieve stable and precise power transmission. The driven wheel tensioning block 17 and belt pressure plate 8 further ensure the reliability of the transmission system. In the drug delivery system, the guide rail 15 provides precise linear motion guidance for the slider, which drives the medicine-pulling plate 11 to push the medicine box. The medicine-blocking plate 12 ensures the medicine box 22 is fixed in position, and the origin baffle 18 and origin signal sensor 19 accurately position the slider at its initial and final positions. Through the close cooperation of these two parts, the belt drive system provides stable power for drug delivery, and the drug delivery system accurately pushes the medicine box, making the medicine box 22 closer to the exit when pushed out, greatly facilitating doctors to pick it up, and improving the stability and positioning accuracy of the entire drug dispensing structure.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
