[0025] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Example 1: Embodiment 1 of the present invention provides a device for batch dispensing of foil-packaged tablets, which is applicable to the batch dispensing method of foil-packaged tablets described in the following embodiments, such as... Figure 1 As shown, it includes: a base 1, a mounting platform 2, a pressing plate 3, two adjusting plates 4, and several support plates 5 located between the two adjusting plates 4, as well as a linkage mechanism 6; the base 1 and the mounting platform 2 are relatively fixed, the pressing plate 3 is located above the mounting platform 2, the pressing plate 3 is elastically connected to the mounting platform 2, the adjusting plates 4 and the support plates 5 are located between the base 1 and the mounting platform 2, the adjusting plates 4 are slidably connected to the base 1, and the linkage mechanism 6 drives the support plates 5 to move.

[0027] A connecting column 14 is provided between the base 1 and the mounting platform 2. The lower end of the connecting column 14 is fixedly connected to the base 1, and the upper end of the connecting column 14 is fixedly connected to the mounting platform 2. A plurality of springs 20 are provided between the mounting platform 2 and the pressing plate 3. One end of each spring 20 is fixedly connected to the upper surface of the mounting platform 2, and the other end of each spring 20 is fixedly connected to the lower surface of the pressing plate 3.

[0028] In one embodiment, the foil-wrapped tablet dispenser is suitable for dispensing tablets from a foil-wrapped blister pack 8. In practical use, such as... Figure 2 As shown, the adjusting plate 4 is used to clamp the medicine plate 8. The medicine plate 8 has a raised surface of the tablets positioned close to the pressing plate 3. The support plate 5 is supported at the gap between each row of tablets on the flat surface of the medicine plate 8. To better apply pressure to the raised surface of the medicine plate 8 by the pressing boss 30, a pressing plate 31 is provided on the bottom surface of the pressing plate 3. The bottom surface of the pressing plate 31 is machined with multiple pressing protrusions 310. The pressing protrusions 310 are arranged in an array, and each pressing protrusion 310 corresponds to one tablet on the medicine plate 8. The arrangement of the array of pressing protrusions 310 depends on the medicine plate 8 being pressed.

[0029] The blister pack 8 has multiple rows of tablets, with gaps between adjacent rows. The blister pack 8 has a flat surface and a raised surface; the side containing the tablets is the raised surface, and the side opposite the raised surface is the flat surface. The flat surface of the blister pack 8 contacts the support plate 5, and the raised surface of the blister pack 8 is located adjacent to the pressing plate 3 to receive the pressure applied by the pressing plate 3.

[0030] The side of the adjusting plate 4 abuts against the edge of the blister pack 8 to hold the blister pack 8 between the two adjusting plates 4. To prevent the blister pack 8 from being bent due to lack of support when the pressing plate 3 is pressed down, a support protrusion 43 is provided on the inner side of the adjusting plate 4 to support the edge of the blister pack 8. The support plate 5 supports the gap between each row of tablets in the blister pack 8. When the pressing plate 3 applies pressure to the protruding surface of the blister pack 8, the support plate 5 acts as a fulcrum. Based on this, there is a predetermined height difference between the adjusting plate 4 and the support plate 5 (as shown in the figure, the height difference can just accommodate the thickness of the blister pack 8). For example, if the thickness of the blister pack 8 is 0.5 mm, then the adjusting plate 4 is about 0.5 mm higher than the support plate 5.

[0031] To prevent damage to the springs 20 due to excessive force during operation, the upper surface of the mounting platform 2 is provided with multiple hollow height-limiting posts 21. These posts 21 are fixedly connected to the mounting platform 2, and some of the springs 20 are housed within the hollow structure of the height-limiting posts 21. When the pressing plate 3 is pressed, the distance between the pressing plate 3 and the mounting platform 2 is limited by the height-limiting posts 21, thereby protecting the springs 20 from excessive compression and damage.

[0032] Insert the pressing tablet 31 into the preset position of the pressing plate 3. Adjust the spacing and position between the support plates 5 through the linkage mechanism 6 so that the support plates 5 are respectively located in the middle of each row of pressing protrusions 310 on the pressing plate 3. Adjust the position between the two adjustment plates 4 so that the distance between the two adjustment plates 4 is the same as the width of the foil-encapsulated medicine plate 8, thus limiting the position of the medicine plate 8. Place the medicine plate 8 between the pressing plate 3 and the support plates 5 with the protruding surface of the encapsulated tablets on the medicine plate 8 facing upwards. The support plates 5 support the medicine plate 8 at the gap between each row of tablets on the flat surface of the medicine plate 8. Press down the pressing plate 3, which will squeeze the protruding surface of the medicine plate 8, squeezing the tablets out of the medicine plate 8 and dropping them into the medicine tray 7. Release the pressing plate 3, which will lift upwards under the force of the spring 20, removing the medicine tray 7 and pouring the tablets into a specific container. Using the foil-encapsulated tablet dispensing device provided by this invention, all tablets on a dispensing plate 8 can be peeled off simultaneously, effectively improving the dispensing efficiency.

[0033] In this invention, the support plate 5 is driven by the linkage mechanism 6 to adjust its spacing and position, such as... Figure 3 As shown, the linkage mechanism 6 includes multiple linkage sliders 60, a power unit 61, a guide rod 62, and a lead screw 63. The multiple linkage sliders 60 are fixedly connected to the support plate 5, driving the support plate 5 to move. Each linkage slider 60 is slidably connected to the guide rod 62. The linkage slider 60 closest to the power unit 61 is threadedly connected to the lead screw 63, and the remaining linkage sliders 60 are slidably connected to the lead screw 63. Multiple connecting rod assemblies 64 are arranged between the linkage sliders 60, and the multiple linkage sliders 60 are connected through the connecting rod assemblies 64. The power unit 61 is fixedly connected to one end of the lead screw 63. Specifically, the linkage slider 60 closest to the power unit 61 is threadedly connected to the lead screw 63. Figure 4 Taking the three linkage sliders 60 shown as an example, the linkage slider 60 closest to the power unit 61 is threadedly connected to the lead screw 63, and its surface is provided with a second threaded hole 601 corresponding to the lead screw 63. The other two linkage sliders 60 are provided with a first through hole 602 on their surfaces. The diameter of the first through hole 602 is larger than the diameter of the lead screw 63 so that the lead screw 63 can pass through the first through hole 602. In addition, each linkage slider 60 is provided with a second through hole 603 on its surface. The second through hole 603 is used to allow the guide rod 62 to pass through and to allow the linkage slider 60 to slide about the guide rod 62 as an axis.

[0034] As mentioned above, the step of moving the support plates 5 through the linkage mechanism 6 to adjust the spacing and position between the support plates 5 includes: driving the lead screw 63 to rotate through the power unit 61, and the lead screw 63 driving the linkage slider 60 closest to the power unit 61 to move along the guide rod 62; the linkage slider 60 drives the connecting rod assembly 64 to compress or extend, so as to synchronously move other linkage sliders 60 along the guide rod 62, thereby adjusting the spacing and position between the support plates 5.

[0035] To guide the sliding path of the linkage slider 60, such as Figure 3 As shown, the upper surface of the base 1 is provided with a receiving groove 10. The two side walls of the receiving groove 10 respectively abut against the two side walls of the linkage slider 60, for guiding the linkage slider 60 to move within the receiving groove 10. The width of the linkage slider 60 matches the width of the receiving groove 10, so that the linkage slider 60 can move guided by the direction of the two side walls of the receiving groove 10. To fix the guide rod 62 and the lead screw 63, the linkage mechanism 6 also includes a first L-shaped mounting plate 65 and a second L-shaped mounting plate 66. The first L-shaped mounting plate 65 and the second L-shaped mounting plate 66 are placed upside down, with the end face of the vertical part of their L-shape fixed to the surface of the receiving groove 10. The two ends of the guide rod 62 are fixedly connected to the first L-shaped mounting plate 65 and the second L-shaped mounting plate 66 respectively, and the two ends of the lead screw 63 are rotatably connected to the first L-shaped mounting plate 65 and the second L-shaped mounting plate 66 respectively.

[0036] In the design process, to ensure that the distance between the linkage sliders 60 remains consistent and that the linkage sliders 60 can move in unison, a linkage assembly 64 is provided between the linkage sliders 60. Multiple linkage sliders 60 are connected through the linkage assembly 64, specifically including, for example... Figure 3 and Figure 4 As shown, when three linkage sliders 60 are provided, the linkage assembly 64 includes a first link 640, a second link 641, a third link 642, and a fourth link 643 arranged sequentially. The ends of each adjacent link are rotatably connected. The upper surface of each linkage slider 60 is provided with a mounting shaft 600. The first link 640, the second link 641, and the third link 642 are rotatably connected to the mounting shaft 600. The lower surface of the horizontal portion of the second L-shaped mounting plate 66 is also provided with a mounting shaft 600. The mounting shaft 600 of the second L-shaped mounting plate 66 is rotatably connected to the fourth link 643.

[0037] Among them, with Figure 3For example, the first connecting rod 640 and the fourth connecting rod 643 are provided with two rotation centers located at their respective ends, and the second connecting rod 641 and the third connecting rod 642 are provided with three rotation centers at their respective ends and center positions; one rotation center of the first connecting rod 640 is rotatably connected to the mounting shaft 600 of the linkage slider 60 near the power unit 61, the other rotation center of the first connecting rod 640 is rotatably connected to the rotation center at one end of the second connecting rod 641, and the middle rotation center of the second connecting rod 641 is connected to the rotation center located at the middle position. The mounting shaft 600 of the linkage slider 60 is rotatably connected; the rotation center of the other end of the second link 641 is rotatably connected to the rotation center of one end of the third link 642, the rotation center in the middle of the third link 642 is rotatably connected to the mounting shaft 600 of the linkage slider 60 near the second L-shaped mounting plate 66, the rotation center of the other end of the third link 642 is rotatably connected to the rotation center of one end of the fourth link 643, and the mounting shaft 600 of the second L-shaped mounting plate 66 is rotatably connected to the rotation center of the other end of the fourth link 643. The reason for setting up the linkage assembly 64 is that, since the size and spacing of the tablets on the medicine plate 8 are equal, the rotation center coupled to the mounting shaft 600 on the first linkage 640, the second linkage 641, and the third linkage 642 is made so that the length of the connecting arm formed by the linkages between adjacent mounting shafts 600 is equal. When the linkage slider 60 connected to the first linkage 640, the second linkage 641, and the third linkage 642 slides, the distance between adjacent linkage sliders 60 can be adjusted synchronously to keep the distance between each adjacent linkage slider 60 consistent, thereby ensuring that the distance between adjacent support plates 5 remains consistent.

[0038] In the linkage mechanism 6, the linkage slider 60 closest to the power unit 61 is threadedly connected to the lead screw 63. The lead screw 63 is driven to rotate by the power unit 61, which is an adjustment knob 610. The adjustment knob 610 is located at one end of the lead screw 63 and is fixedly connected to one end of the lead screw 63. The surface of the adjustment knob 610 is provided with anti-slip patterns. During operation, rotating the adjustment knob 610 causes the lead screw 63 to rotate. Since the linkage slider 60 near the power unit 61 is threadedly connected to the lead screw 63, when the lead screw 63 rotates, the linkage slider 60 threadedly connected to the lead screw 63 will move horizontally in the direction of the lead screw 63. For example, when the lead screw 63 rotates clockwise, the linkage slider 60 moves away from the power unit 61, and when the lead screw 63 rotates counterclockwise, the linkage slider 60 moves closer to the power unit 61. Since there is a connecting rod assembly 64 between the linkage sliders 60, when the linkage slider 60 threadedly connected to the lead screw 63 moves, the other linkage sliders 60 will also move together under the drive of the connecting rod assembly 64 above it, thereby achieving the effect of adjusting the distance and position between the support plates 5.

[0039] In one embodiment, such as Figure 5 As shown, the power unit 61 is a motor 611, which is located at one end of the lead screw 63. The motor shaft of the motor 611 is fixedly connected to the lead screw 63. The motor 611 drives the lead screw 63 to rotate. The motor 611 is fixed to the first L-shaped mounting plate 65. The process of using motor 611 to drive lead screw 63 to rotate, thereby moving support plate 5, is the same as the process of using adjustment knob 610. The difference is that a control unit (not shown in the figure) is set up to control the forward and reverse rotation of motor 611, thereby controlling lead screw 63 to rotate clockwise or counterclockwise. The control unit receives signals indicating whether motor 611 should rotate forward, reverse, or stop. The control unit processes the received signals to determine the operating state of motor 611 (forward, reverse, or stop). Based on the processing result, the control unit generates corresponding control signals to change the current flow direction in motor windings by controlling motor driver. When motor 611 needs to rotate forward, the control unit will make forward current flow through motor 611 windings; when reverse rotation is required, it will make reverse current flow. The control unit and motor driver (not shown in the figure) will be connected to a microcontroller unit (MCU), microprocessor unit (MPU), or other integrated circuits with control functions.

[0040] Because the linkage mechanism 6 contains easily damaged structures such as the linkage assembly 64, such as... Figure 6 As shown, the outer side of the linkage mechanism 6 is covered with a housing 67, which is fixedly connected to the base 1 by snap-fit ​​or adhesive. The outer side facing the mounting platform 2 is open.

[0041] For the medicine tray 7, since the widths of different medicine plates 8 vary, the width between the two adjusting plates 4 also varies. If the medicine tray 7 is placed flush with the adjusting plates 4, then the specifications of the medicine tray 7 need to be customized according to the dimensions of the medicine plates 8. Different sizes of medicine tray 7 need to be customized to improve the versatility of the medicine tray 7. Figure 7As shown, the upper surface of the base 1 is provided with a sink 11, and the medicine tray 7 is placed in the sink 11. The lower surface of the support plate 5 is slidably connected to the medicine tray 7. The distance between the lower surface of the support plate 5 and the surface of the sink 11 matches the thickness of the medicine tray 7. The front end of the sink 11 is provided with a first inclined surface 110, which is used to allow tablets that fall onto the edge of the sink 11 to slide into the medicine tray 7. By placing the medicine tray 7 in the sink 11 so that it is lower than the lower surface of the adjusting plate 4, it is not necessary to customize medicine trays 7 of different sizes according to the size of the medicine blister 8. The same medicine tray 7 can be used for medicine blister 8 of different sizes, which improves the versatility of the medicine tray 7.

[0042] The above scheme mentions that the adjusting plate 4 and the base 1 are slidably connected. Specifically, the implementation scheme can be as follows: the surfaces of the protrusions on both sides of the recess 11 are respectively provided with first sliding grooves 12, such as... Figure 8 As shown, a guide slider 40 is provided at the bottom of the adjusting plate 4, and the guide slider 40 is slidably connected to the first slide groove 12; wherein, since the adjusting plate 4 may move above the sink 11, the bottom height of the first slide groove 12 is slightly higher than the height of the medicine tray 7 to prevent the medicine tray 7 from blocking the movement of the adjusting plate 4.

[0043] After the adjusting plate 4 is moved to the preset position, if the adjusting plate 4 is not fixed, its position may change during operation due to pressure from the pressing plate 3 or accidental contact. Therefore, if... Figure 7 and Figure 8 As shown, the adjusting plate 4 is L-shaped, with a groove 41 on its horizontal portion. The base 1 has a first threaded hole 13, and the projection of the groove 41 onto the base 1 covers the first threaded hole 13. A fixing knob 42 passes through the groove 41 and is threaded into the first threaded hole 13. The bottom surface of the handle of the fixing knob 42 abuts against the surface of the adjusting plate 4. The handle has an anti-slip pattern. During the movement of the adjusting plate 4, the fixing knob 42 is in a loose state. When the adjusting plate 4 is moved to a suitable position, the fixing knob 42 is tightened to fix the adjusting plate 4. During normal movement of the adjusting plate 4, the projection of the groove 41 onto the base 1 always covers the threaded hole. To facilitate the movement of the adjusting plate 4, a handle protrusion 44 is provided on the outer end face of the horizontal plane of the adjusting plate 4. The handle protrusion 44 is used to receive external force to move the adjusting plate 4.

[0044] For pressing plate 3, such as Figure 9As shown, the lower surface of the pressing plate 3 is provided with a pressing boss 30, and the middle part of the mounting platform 2 is provided with a through groove 22 for accommodating the pressing boss 30. The pressing piece 31 is disposed on the bottom surface of the pressing boss 30. In actual use, it is necessary to replace the pressing piece 31 with a suitable one according to the distribution of the tablets on the blister pack 8. Therefore, the pressing piece 31 is slidably connected to the pressing boss 30 to facilitate the removal of the pressing piece 31. The slidable connection between the pressing piece 31 and the pressing boss 30 specifically includes, for example... Figure 10 As shown, the pressing plate 31 has mounting wings 311 on both sides, the bottom surface of the pressing boss 30 has a mounting groove 300, and the two sides of the mounting groove 300 have second sliding grooves 301. The mounting wings 311 and the second sliding grooves 301 are slidably connected. In practical applications, to ensure that the tablet is ejected from the medicine plate 8 in one go, when the pressing plate 3 is pressed to its limit position, the lowest point of the pressing protrusion 310 is slightly lower than the highest point of the support plate 5, thereby squeezing the tablet out of the medicine plate 8.

[0045] Based on the above solution, embodiments of the present invention provide a method for batch dispensing of foil-packaged tablets. This method is applied to the foil-packaged tablet batch dispensing device described in the foregoing embodiments, such as... Figure 11 As shown, it includes: In step 1, the pressing tablet 31 adapted to the medicine plate 8 is inserted into the preset position of the pressing plate 3, and the spacing and position between the support plates 5 are adjusted so that the support plates 5 are respectively located in the middle of each row of pressing protrusions 310 on the pressing tablet 31.

[0046] In step 2, the position between the two adjustment plates 4 is adjusted so that the distance between the two adjustment plates 4 is the same as the width of the foil-encapsulated medicine plate 8, thereby limiting the position of the medicine plate 8.

[0047] In step 3, the blister pack 8 is placed between the pressing plate 3 and the support plate 5, with the protruding surface of the blister pack 8 containing the tablets facing upwards, and the support plate 5 is supported at the gap between each row of tablets on the flat surface of the blister pack 8.

[0048] In step 4, the pressing plate 3 is pressed down, which will squeeze the raised surface of the medicine plate 8, squeezing the tablet out of the medicine plate 8 and dropping it into the medicine tray 7.

[0049] In step 5, the medicine tray 7 is removed and the tablets are poured into a specific container.

[0050] according to Figures 1-10The lower surface of the pressing plate 3 is provided with pressing protrusions 30, and the pressing protrusions 310 are arranged in an array. Step 1 specifically includes: inserting the pressing piece 31 into the bottom surface of the pressing protrusions 30; driving the support plate 5 to move through the linkage mechanism 6, adjusting the spacing and position between the support plates 5, so that the support plates 5 are respectively located in the middle of each row of pressing protrusions 310 on the pressing piece 31, so that the pressing protrusions 310 correspond to the protrusions of the tablets on the medicine plate 8.

[0051] Example 2: In practice, the foil-wrapped tablet dispensing device provided in the aforementioned embodiments can basically meet the dispensing needs, but some tablets may fail to dispense, requiring manual removal of the remaining tablets. The inventors discovered through research that the reason for tablet leakage is due to two problems with the device in Embodiment 1, which are described below. Figure 2 Explanation: Problem 1: The lower surface of the medicine plate 8 is supported by three support plates 5, and the edge of the medicine plate only overlaps the upper surface of the vertical part of the L-shaped adjusting plate 4. During the pressing process, the medicine plate 8 is prone to shaking, causing it to shift. There is a misalignment between the pressing protrusion 310 and the corresponding tablet, making it impossible to accurately press out all the tablets. Problem 2: Due to the certain toughness of the aluminum foil, if the pressing force is too small, the aluminum foil cannot be broken, and the tablet cannot be ejected. In addition, a larger pressing force will further increase the probability of the medicine plate 8 shaking.

[0052] To address this issue, an improved solution is provided based on the foregoing embodiments, see below. Figure 12 and Figure 13 A blade 50 is provided on the side of the support plate 5 where the medicine plate is inserted. A clamp 46 is provided on the upper surface of the vertical part of the L-shaped adjusting plate 4. When the clamp 46 clamps the edge of the medicine plate, the medicine plate can slide inward along the clamping surface under the action of force. The height of the blade 50 is basically the same as or slightly higher than the height of the upper surface of the vertical part of the L-shaped adjusting plate 4, so that when the medicine plate is clamped by the clamp 46, the blade 50 can cut through the tin foil.

[0053] Figure 12 and Figure 13 The surface of clip 46 shown in the image is beveled (as shown in the image). Figure 12(The side marked with the 'S' in the diagram) When the pressing plate 3 is pressed down so that the pressing boss 30 abuts against the surface of the clip 46, the contact area between the surface of the clip 46 and the pressing boss 30 is relatively small (basically, only one edge of the pressing boss 30 contacts the surface of the clip 46). This results in a more concentrated pressing force applied to the clip 46, but it does not affect actual use. To disperse the pressing force applied by the pressing boss 30 to the clip 46, in an optional embodiment, the front end of the surface of the clip 46 can be set as a plane, so that the pressing boss 30 and the front end of the clip 46 form a surface-to-surface contact, increasing the contact area between the two.

[0054] Based on the device provided in this embodiment, there are also corresponding modifications to the usage method. Specifically, the operation process of placing the medicine plate 8 between the pressing plate 3 and the support plate 5 in Embodiment 1 has been changed. In this embodiment, firstly, the two sides of the medicine plate 8 are clamped by the clips 46 provided on the adjusting plate 4, and then the medicine plate 8 is pushed inward. The blade 50 provided on the support plate 5 gradually cuts the foil of the medicine plate 8. After the medicine plate 8 is pushed into place, the foil of at least one side of each tablet is pre-cut. Then, the action of pressing the pressing plate 3 is performed.

[0055] In this embodiment, the medicine plate 8 is not only supported by the support plate 5, but also stably clamped vertically by the clips 46 on both sides, ensuring minimal wobbling during pressing and guaranteeing the correspondence between the pressing protrusion 310 and the medicine tablet. During use, the clips 46 are first used to clamp the two edges of the medicine plate, and then the medicine plate is pushed inward. During this process, the foil of the medicine plate is gradually cut by the blade. After the medicine plate is pushed into place, the pressing plate 3 is pressed down, and the pressing protrusion 310 pushes out the corresponding medicine tablet. Since the foil on at least one side of each medicine tablet has been pre-cut, only a small force needs to be applied to the pressing plate 3 to easily push the medicine tablet out, further reducing the probability of the medicine plate wobbling. According to the device provided in this embodiment, almost all the medicine tablets on the medicine plate 8 can be pushed out, improving the efficiency of medicine dispensing.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
