[0038] The rocker arm mechanism 30 is symmetrically arranged in two groups, namely the first rocker arm mechanism 30 and the second rocker arm mechanism 30, and the first rocker arm mechanism 30 and the second rocker arm mechanism 30 have the same structure; the lifting mechanism 40 is symmetrically arranged in two groups, namely the first lifting mechanism 40 and the second lifting mechanism 40, and the first lifting mechanism 40 and the second lifting mechanism 40 have the same structure; the swing arm mechanism 50 is symmetrically arranged in two groups, namely the first swing arm mechanism 50 and the second swing arm mechanism 50, and the first swing arm mechanism 50 and the second swing arm mechanism 50 have the same structure; the first rocker arm mechanism 30, the first lifting mechanism 40 and the first swing arm mechanism 50 are arranged on one side of the through slot 11, and the second rocker arm mechanism 30, the second lifting mechanism 40 and the second swing arm mechanism 50 are arranged on the other side of the through slot 11.

[0039] When in use, a whole stack of medicine basket 60 is placed in the through slot 11 of the mounting seat 10, and the medicine basket 60 is located on the L-shaped supporting plate 41. The L-shaped supporting plate 41 holds up the bottom medicine basket 60. When the medicine basket 60 needs to be taken, the medicine basket 60 dispensing device is started, and the driving mechanism 20 starts to work. The driving mechanism 20 drives the cam 31 to drive the eccentric wheel 32 and the first connecting rod 33 to perform a circular motion, and the second connecting rod 42 moves with the first connecting rod 33, thereby driving the L-shaped supporting plate 41 to perform a lifting motion. While the second connecting rod 42 is performing the lifting motion, the two ends of the second connecting rod 42 move along the curved track 431 of the profiling plate 43. The deflection force support is achieved by the sliding cooperation between the second connecting rod 42 and the profiling plate 43, thereby ensuring that the L-shaped supporting plate 41 does not deflect when performing the lifting motion, so that the L-shaped supporting plate 41 can also stably hold the medicine basket 60 when performing the lifting motion. When the bottom medicine basket 60 is placed on the flat surface 512 of the swing arm 51, the bottom medicine basket 60 is lifted by the swing arm 51, and the rocker arm mechanism 30 continues to make circular motion, driving the L-shaped supporting plate 41 to deviate from the bottom medicine basket 60 through a curved path, and move up empty to a suitable position to hook the edge of the upper medicine basket 60, lifting the upper medicine basket 60 together. When it continues to move upward to a certain height, the raised portion of the cam 31 triggers the swing arm 51 to deflect, and the flat surface 512 of the swing arm 51 leaves the medicine basket 60, dropping the medicine basket 60 remaining on the swing arm 51, completing the operation of dispensing one medicine basket 60, and the swing arm 51 is reset under the push of the spring reset assembly 52.

[0040] The medicine basket 60 delivery device of the embodiment of the present invention includes a mounting base 10, a driving mechanism 20, a rocker mechanism 30, a lifting mechanism 40 and a swing arm mechanism 50. The driving mechanism 20, the rocker mechanism 30, the lifting mechanism 40 and the swing arm mechanism 50 cooperate with each other to achieve the purpose of automatically dispensing one medicine basket 60 at a time. The overall structure of the device is simple, the size is small, the space occupied is small, and the practicality is strong.

[0041] Preferably, the mounting base 10 is arranged in a U-shape or a U-shape. In this embodiment, the mounting base 10 is arranged in a U-shape, including a first extension portion 12, a second extension portion 13 and a connecting portion 14. The first extension portion 12 and the second extension portion 13 are symmetrically arranged. The first extension portion 12 and the second extension portion 13 are connected by the connecting portion 14. The driving mechanism 20 is arranged on the connecting portion 14, the first rocker arm mechanism 30, the first lifting mechanism 40 and the first swing arm mechanism 50 are arranged on the first extension portion 12, and the second rocker arm mechanism 30, the second lifting mechanism 40 and the second swing arm mechanism 50 are arranged on the second extension portion 13.

[0042] Furthermore, the first extension portion 12 and the second extension portion 13 have the same structure. The first extension portion 12 is formed with a mounting groove 121 connected to the through groove 11. The first lifting mechanism 40 is arranged in the mounting groove 121, and the L-shaped supporting plate 41 extends from the mounting groove 121 to the through groove 11. The first rocker arm mechanism 30 is supported on the first extension portion 12 by a fixing plate and a bearing, and the first connecting rod 33 extends into the mounting groove 121. The first swing arm mechanism 50 is connected to the first extension portion 12 through a rotating shaft, and the spring return assembly 52 is installed in the mounting groove 121.

[0043] Specifically, the contoured plate 43 is fixed in the mounting groove.

[0044] Preferably, the driving mechanism 20 includes a driving member 21 and a transmission gear set 22, the transmission gear set 22 includes a driving gear 23 connected to the output shaft of the driving member 21, a first driven gear 24 connected to the first rocker mechanism 30 and a second driven gear 25 connected to the second rocker mechanism 30, the first driven gear 24 and the second driven gear 25 are respectively located on both sides of the driving gear 23, and are respectively engaged with the driving gear 23 for transmission.

[0045] The medicine basket 60 dispensing device of this embodiment provides a transmission gear set 22 to simultaneously transmit synchronously the first rocker mechanism 30 and the second rocker mechanism 30 , and the transmission method is simple and reliable.

[0046] Furthermore, a third driven gear 26 is provided between the driving gear 23 and the second driven gear 25 , and the driving gear 23 drives the second driven gear 25 to rotate via the third driven gear 26 .

[0047] Preferably, in order to better cooperate with the contour plate 43 to achieve the purpose of anti-deflection, sliding parts 421 are provided at both ends of the second connecting rod 42.

In this way, the lifting mechanism 40 can lift the medicine basket 60 more stably.

[0050] Of course, each group of lifting mechanisms 40 can also be provided with only one L-shaped supporting plate 41. In this case, the two groups of lifting mechanisms 40 should not be symmetrically arranged. The L-shaped supporting plates 41 of the two groups of lifting mechanisms 40 can be centrally symmetrically arranged, and can also steadily lift the medicine basket 60.

[0051] Preferably, the spring return assembly 52 includes a return push plate 521 and a spring 522. One end of the spring 522 is connected to the return push plate 521, and the other end is fixed to the mounting base 10. The return push plate 521 contacts the swing arm 51. When the protrusion of the cam 31 leaves the swing arm 51, the swing arm 51 is returned to its original position under the elastic force of the spring 522. The provision of the return push plate 521 enables the spring 522 to more evenly transmit the force to the swing arm 51.

[0052] It is understandable that the spring return assembly 52 may also consist of only a spring 522 , with one end of the spring 522 being fixed on the mounting seat 10 and the other end being in contact with the swing arm 51 .
