[0021] With the rapid development of the medical industry, the workload of hospital pharmacies is increasing day by day. The traditional manual drug collection method has many problems such as low efficiency, high error rate, and high labor cost. At present, there are many kinds of automated drug storage and retrieval equipment on the market, including traditional shelf systems that require manual walking to retrieve drugs, ground-type automatic drug dispensers that use mechanical arms to move on fixed tracks to retrieve drugs, and vertical automatic storage and retrieval medicine cabinets that use vertical lifting to store and retrieve drugs. However, these existing technologies generally occupy a large amount of ground space, which may cause equipment congestion during peak hours in hospitals and affect drug retrieval efficiency.
[0022] Reference Figures 1 to 13 The present application provides a medicine picking robot, including a walking mechanism 100, a scissor lift mechanism 200, a traction mechanism 300, a medicine grabbing mechanism 400 and a medicine basket 500.
[0023] The walking mechanism 100 includes a track 101, a base plate 102 and a first driving device 103. The track 101 is an I-beam structure. The upper side wing plate 104 of the track 101 is used to connect to the ceiling. First rollers 105 are installed at the four corners of the top surface of the base plate 102. The wheel surface of the first roller 105 presses on the upper surface of the lower side wing plate 106 of the track 101. Four second rollers 107 are installed on the top surface of the base plate 102. The four second rollers 107 are distributed on both sides of the track 101 in pairs. The wheel surface of the second roller 107 is provided with an annular groove. The annular groove on the second roller 107 is stuck on the side ridge of the lower side wing plate 106 of the track 101. The first driving device 103 includes a first power component 109, a gear 110 and a chain 111. The first power component 109 is fixed to the lower surface of the base plate 102. The gear 110 is connected to the power output of the first power component 109. The chain 111 is laid on the lower surface of the lower side wing plate 106 of the track 101, and the chain 111 extends along the length direction of the track 101. The bottom plate 102 is provided with a strip hole corresponding to the position of the gear 110, and the gear 110 extends into the strip hole and meshes with the chain 111. Four third rollers 132 are installed on the lower surface of the bottom plate 102. The four third rollers 132 are distributed in pairs on both sides of the chain. The wheel surface of the third roller 132 presses on the lower surface of the lower side wing plate 106 of the track 101. The scissor lift mechanism 200 is vertically connected to the bottom plate 102, and the traction mechanism 300 is arranged on the bottom plate 102. The traction mechanism 300 is used to drive the scissor lift mechanism 200 to move up and down. The medicine grabbing mechanism 400 is installed at the lifting and lowering end of the scissor lift mechanism 200. The medicine basket 500 is connected below the medicine grabbing mechanism 400 to receive the medicine grabbed by the medicine grabbing mechanism 400.
[0024] In the present application, the upper side wing plate 104 of the track 101 is fixed on the ceiling, thereby fixing the track 101, and using four first rollers 105 to press against the upper surface of the lower side wing plate 106 of the track 101 to achieve the vertical positioning of the bottom plate 102, and using four second rollers 107 to press against the side ridges of the lower side wing plate 106 of the track 101 to achieve the horizontal positioning of the bottom plate 102. When the bottom plate 102 moves along the track 101, the four third rollers 132 will roll synchronously on the lower surface of the lower side wing plate 106 of the track 101, so that the first roller 105 is pressed on the upper surface of the lower side wing plate 106 of the track 101, the third roller 132 is pressed on the lower surface of the lower side wing plate 106 of the track 101, and the second roller 107 is pressed on the side edge of the lower side wing plate 106. The first roller 105, the second roller 107 and the third roller 132 can ensure the stability of the entire walking mechanism 100 during the walking process along the track 101. Therefore, the medicine taking robot is very stable during the moving medicine taking process.
[0025] The first power component 109 drives the gear 110, and the gear 110 drives the entire walking mechanism 100 to move along the chain 111 by meshing with the chain 111. This mode of moving by meshing the gear 110 with the chain 111 will not slip.
[0026] During operation, the base plate 102 drives the scissor lift mechanism 200 to move to the position where the medicine is to be taken, and then the medicine grabbing mechanism 400 on the scissor lift mechanism 200 starts to work to take the medicine from the medicine shelf and put it into the medicine basket 500, and then the first drive device 103 continues to drive the base plate 102 to move on the track 101, so that the base plate 102 drives the scissor lift mechanism 200 and the medicine basket 500 to move to the doctor's side, making it convenient for the doctor to directly take out the medicine.
[0027] This medicine-taking robot is installed on the ceiling. Through the walking mechanism 100 and the scissor-type lifting mechanism 200, the medicine-grabbing mechanism 400 is moved to different layers of the medicine shelf to take out medicines. Compared with the traditional medicine-taking robot set on the ground, the medicine-taking robot of the present application does not occupy the ground space, can effectively alleviate the congestion problem in the pharmacy, and improve the efficiency of medicine-taking.
[0028] A connecting column 108 is installed on the upper wing plate 104 of the I-beam, and the connecting column 108 is fixed on the ceiling, thereby fixing the track 101.
[0029] The bottom plate 102 is a rectangular flat plate structure, and the four first rollers 105 are respectively installed at the four corners of the upper surface of the bottom plate 102 through four first roller 105 mounting seats 138 .
[0030] In order to increase the friction between the first roller 105 and the upper surface of the lower wing plate 106 of the track 101 , a transverse groove is provided on the wheel surface of the first roller 105 .
[0031] In some other embodiments, the first power component 109 is fixed to the lower surface of the base plate 102 through the mounting plate 112, the gear 110 is rotatably mounted on the mounting plate 112, the first pulley 114 is mounted on the power output shaft of the first power component 109, the second pulley 115 is mounted on the rotating shaft of the gear 110, and the first pulley 114 and the second pulley 115 are connected through the first synchronous belt 116. During operation, the first power component 109 drives the first pulley 114, the first pulley 114 drives the second pulley 115 to rotate through the first synchronous belt 116, and the second pulley 115 drives the gear 110 to rotate.
[0032] Reference Figure 8 In some embodiments, a conductive strip is laid on the inner side of the track 101, and the conductive strip extends along the length direction of the track 101. A conductive device 117 is provided on the base plate 102, and the conductive device 117 is connected to the first power component 109. The conductive device 117 includes a U-shaped seat 118, a wire contact fixing rod 119 and a conductive contact 120. The U-shaped seat 118 is installed on the base plate 102 and is located on one side of the track 101. The wire contact fixing rod 119 is installed in the U-shaped seat 118. One end of the wire contact fixing rod 119 extends close to the conductive strip. The conductive contact 120 is installed on the wire contact fixing rod 119 and contacts the conductive strip. The conductive contact 120 is connected to the first power component 109.
[0033] Specifically, two conductive strips are installed on the middle vertical plate 130 of the track 101, one is the neutral line and the other is the live line. Two wire contact fixing rods 119 are provided, and both wire contact fixing rods 119 are arranged inside the U-shaped seat 118. One of the wire contact fixing rods 119 is provided with a conductive contact 120 for contacting the live wire conductive strip, and the other wire contact fixing rod 119 is provided with a conductive contact 120 for contacting the neutral wire conductive strip. During operation, when the bottom plate 102 moves along the track 101, the two conductive contacts 120 will also contact and move synchronously on the two conductive strips, thereby providing power for the entire walking mechanism 100.
[0034] In order to keep the conductive contact 120 pressed against the conductive bar at all times, and to ensure that the conductive contact 120 can also contact the conductive bar when the walking mechanism 100 turns, in some embodiments, the wire contact fixing rod 119 is hinged to the U-shaped seat 118, and the wire contact fixing rod 119 can rotate horizontally with the hinge point as the center of the circle, and the end of the wire contact fixing rod 119 away from the conductive contact 120 is located inside the U-shaped seat 118, and the end of the wire contact fixing rod 119 located inside the U-shaped seat 118 is connected to the inner wall of the U-shaped seat 118 through a horizontally arranged first spring 121.
[0035] Specifically, one end of the two wire contact fixing rods 119 located inside the U-shaped seat 118 is connected to the inner wall of the U-shaped seat 118 through a horizontal first spring 121. In this way, under the elastic force of the first spring 121, the wire contact fixing rod 119 will always press the conductive contact 120 against the conductive strip to prevent the conductive contact 120 from being detached from the conductive strip and powering off.
[0036] In the present application, the wire contact fixing rod 119 is a bent rod structure, and the bent part of the wire contact fixing rod 119 is fixed inside the U-shaped seat 118 through a rotating shaft. The two wire contact fixing rods 119 share a rotating shaft, and the two wire contact fixing rods 119 are arranged in the up and down direction to reduce space occupancy.
[0037] In some embodiments, a fixing seat 122 is installed on the upper surface of the base plate 102, and the second roller 107 is hinged to the fixing seat 122 through a roller mounting seat 123. The roller mounting seat 123 can rotate horizontally with the hinge point as the axis. A limit plate 124 is set on the base plate 102, and the limit plate 124 and the roller mounting seat 123 are connected by a second spring 125. The second spring 125 is used to apply a force to the roller mounting seat 123 so that the second roller 107 is pressed against the side ridge of the lower side wing plate 106 of the track 101. An adjusting bolt 126 is installed on the limit plate 124, and one end of the adjusting bolt 126 is connected to the second spring 125, and the other end is located on the outer side of the limit plate 124.
[0038] During the movement of the bottom plate 102, under the force of the second spring 125, the second roller 107 will always remain pressed against the side ridge of the lower wing plate 106 of the track 101, so that the second roller 107 moves more flexibly, ensuring that the walking mechanism 100 turns smoothly on the track 101 and will not be stuck by the four second rollers 107. The preload force of the second spring 125 can be adjusted by rotating the adjustment bolt 126, so that the force applied by the second spring 125 to the second roller 107 remains stable.
[0039] Reference Figure 6In some embodiments, switches 127 are installed at both ends of the bottom plate 102 along the length direction of the track 101. The switches 127 include a photoelectric switch 128, a fixed block 129, a sliding shaft 130, and a third spring 140. The fixed block 129 and the photoelectric switch 128 are both fixed on the lower surface of the bottom plate 102. The photoelectric switch 128 is located on the inner side of the fixed block 129 and is arranged at an interval with the fixed block 129. The photoelectric switch 128 is connected to the first power component 109. A through hole extending along the length direction of the track 101 is provided inside the fixed block 129. The sliding shaft 130 is assembled in the through hole. A first baffle 131 is provided at one end of the sliding shaft 130 facing the photoelectric switch 128. The first baffle 131 is used to trigger the photoelectric switch 128. A third spring 140 is sleeved on the sliding shaft 130. One end of the third spring 140 is connected to the fixed block 129, and the other end is connected to the end of the sliding shaft 130.
[0040] When the walking mechanism 100 moves into position, the end of the sliding shaft 130 will be squeezed, causing the sliding shaft 130 to slide in the through hole, and the third spring 140 will be compressed. When the sliding shaft 130 moves to the first blocking piece 131 to trigger the photoelectric switch 128, the photoelectric switch 128 sends a signal to the first power component 109. At this time, the first power component 109 stops driving, thereby achieving the precise positioning of the entire walking mechanism 100.
[0041] In some embodiments, the third roller 132 is installed on the lower surface of the base plate 102 through an installation mechanism 133. The installation mechanism 133 includes a T-block 134, a connecting rod 135 and a fourth spring 136. The T-block 134 is fixedly connected to the lower surface of the base plate 102, the middle part of the connecting rod 135 is hinged to the T-block 134, the third roller 132 is installed at one end of the connecting rod 135, and the fourth spring 136 is installed at the other end of the connecting rod 135. The fourth spring 136 is connected to the lower surface of the base plate 102, and the fourth spring 136 is used to apply a force to the connecting rod 135 so that the connecting rod 135 drives the third roller 132 to be pressed against the lower surface of the lower side wing plate 106 of the track 101.
[0042] During walking, under the action of the fourth spring 136, the third roller 132 is always kept pressed against the lower surface of the lower side wing plate 106 of the track 101. Therefore, the third roller 132 can prevent the base plate 102 from jumping during the movement along the track 101, thereby ensuring the stability of the entire walking mechanism 100.
[0043] Reference Figure 7 In some embodiments, the traction mechanism 300 includes a second driving device 301, a winding drum 302 and a traction rope, the winding drum 302 is connected to the power output end of the second driving device 301, one end of the traction rope is connected to the lifting end of the scissors lift mechanism 200, and the other end is wound around the winding drum 302.
[0044] During operation, the second driving device 301 drives the winding drum 302 to rotate, and the winding drum 302 drives the scissor lift mechanism 200 to move up and down by retracting and releasing the traction rope.
[0045] Reference Figure 7 In some embodiments, the second driving device 301 includes a second power component 303, a driving wheel 304, a driven wheel 305, a second synchronous belt, a transmission shaft 306, a first transmission gear 307 and a second transmission gear 308. The second power component 303 is fixed on the base plate 102, the driving wheel 304 is installed at the power output end of the second power component 303, the transmission shaft 306 is installed on the base plate 102 through a bearing seat 309, the winding drum 302 is fixed on the transmission shaft 306 and is coaxially arranged with the transmission shaft 306, the driven wheel 305 is installed at one end of the transmission shaft 306, and the second synchronous belt connects the driving wheel 304 and the driven wheel 305.

When the scissor lift mechanism 200 needs to rise, the second power component 303 drives the driving wheel 304 to rotate forward, and when the scissor lift mechanism 200 needs to descend, the second power component 303 drives the driving wheel 304 to rotate reversely.

[0072] When the transmission mechanism drives the second baffle 425 on the slide 403 to move to the reset photoelectric switch 422, it means that the slide 403 has moved to the origin. When it is necessary to pick up medicine, the transmission mechanism drives the slide 403 to move.
