Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a pick-and-place device and a medical refrigerator. Background Art

[0002] Medical refrigerators are specialized refrigerators used to store specialized medications such as drugs, vaccines, enzymes, hormones, stem cells, platelets, semen, skin transplants, animal tissue samples, extracted RNA, gene libraries, and some important biological and chemical reagents. Medical refrigerators feature a digital temperature control system with a typical temperature adjustment range of 2 to 8°C.

[0003] When the medical refrigerator's access device drives the mobile tray to move relative to the refrigerator body, the drive mechanism drives the mobile tray through a certain range of motion. When the refrigerator body's storage space is large, especially when the size of the refrigerator body is larger than the range of motion of the mobile tray driven by the drive mechanism, more than two drive mechanisms are required, which undoubtedly increases the space required to install the access device. The drive mechanism of traditional medical refrigerators occupies a large amount of space in the refrigerator body. Under the condition that the medical refrigerator meets the predetermined storage requirements, the installation of more than two drive mechanisms requires the volume of the refrigerator body, resulting in the inability to further reduce the size of the refrigerator body.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] like Figures 1 to 3 As shown, a medical refrigerator 10 according to an embodiment includes a mobile tray 100 and a pick-and-place device 200, wherein the pick-and-place device 200 is used to drive the mobile tray 100 to move. Figure 4 In one embodiment, the pick-and-place device 200 includes a frame 210, a sliding plate 220, a first drive mechanism 230, a movable plate 240, and a second drive mechanism 250. The sliding plate 220 is slidably connected to the frame 210. The first drive mechanism 230 is disposed on the frame 210. The power output end of the first drive mechanism 230 is connected to the sliding plate 220, and the first drive mechanism 230 drives the sliding plate 220 to slide relative to the frame 210.

[0035] like Figure 4 As shown, in one embodiment, the moving plate 240 is slidably connected to the sliding plate 220. Figure 5 and Figure 6 The second driving mechanism 250 includes a moving assembly 252, a fixed plate 254, and a lifting assembly 256. The moving assembly 252 is disposed on the frame 210, and the fixed plate 254 is connected to the power output end of the moving assembly 252, so that the power output end of the moving assembly 252 drives the fixed plate 254 to move relative to the frame 210.

[0036] like Figure 5 and Figure 6 As shown, in one embodiment, a lifting assembly 256 is disposed on the fixed plate 254, and a power output end of the lifting assembly 256 is used to plug into the movable plate 240 when driving the movable plate 240. The output direction of the power output end of the movable assembly 252 is at an angle to the output direction of the power output end of the lifting assembly 256, so that the power output end of the lifting assembly 256 can be reliably plugged into the movable plate 240 during the sliding process of the movable plate 240. In this embodiment, when it is necessary to drive the movable plate 240 to slide relative to the sliding plate 220, first, the power output end of the lifting component 256 is plugged into the movable plate 240, and then the movable component 252 drives the fixed plate 254 to move. Since the lifting component 256 is provided on the fixed plate 254 and the power output end of the lifting component 256 is plugged into the movable plate 240, the fixed plate 254 drives the lifting component 256 and the movable plate 240 to move, thereby driving the movable plate 240 to slide relative to the sliding plate 220, and then the second driving mechanism 250 drives the movable plate 240 to slide relative to the sliding plate 220.

[0037] like Figure 3 and Figure 6 As shown, in one embodiment, the mobile tray 100 is connected to the mobile plate 240. In this embodiment, the direction in which the sliding plate 220 slides relative to the frame 210 is defined as a first direction. The direction in which the mobile plate 240 slides relative to the sliding plate 220 is defined as a second direction, where the first direction and the second direction are the same. The travel of the mobile plate 240 as the sliding plate 220 slides relative to the frame 210 in the first direction is defined as a first travel. The travel of the mobile plate 240 as the sliding plate 220 slides relative to the frame 210 in the second direction is defined as a second travel.

[0038] like Figure 3 and Figure 5 As shown, in one embodiment, the medical refrigerator 10 further includes a cabinet 300. A rack 210 is disposed on the cabinet 300. It should be noted that the rack can be fixed to the cabinet or slidably disposed therein. In one embodiment, the retrieval device 200 further includes a connecting plate 260, through which the rack 210 is connected to the cabinet 300, allowing the rack 210 to be mounted on the cabinet 300. In other embodiments, the rack can also be slidably disposed on the cabinet's supporting mechanism.

[0039] In one embodiment, the pick-and-place device 200 is used to transport the mobile tray 100 from a first position to a second position within the cabinet 300. It should be noted that the first position and the second position may be any two different positions within the cabinet. Before the pick-and-place device is activated, the mobile plate 240 is at one end of the sliding plate 220, which is in the middle of the frame 210. When it is necessary to move from the first position to the second position, the movable plate 240 first slides relative to the sliding plate 220 to one end close to the first position; then the first driving mechanism 230 drives the sliding plate 220 to move toward the end close to the first position until the sliding plate 220 moves to the first position; then the movable tray is placed on the movable plate 240; then the first driving mechanism 230 drives the sliding plate 220 to move in the opposite direction to the middle position of the frame 210; then the lifting assembly 256 drives the movable plate 240 to slide on the sliding plate 220, so that the movable plate 240 moves from one end close to the first position to one end close to the second position; then the first driving mechanism 230 drives the sliding plate 220 to move in the direction close to the second position to the second position; finally, the movable tray is placed in the second position, so that the picking and placing device moves the movable tray from the first position to the second position. Under the same length of the frame 210, the travel of the mobile tray 100 is undoubtedly increased by the sliding travel of the mobile plate 240, which increases the movement travel of the pick-and-place device 200 to drive the mobile tray 100, reduces the number of drive mechanisms, and solves the problem that the medical refrigerator 10 with a large storage capacity cannot be further reduced.

[0040] In the aforementioned pick-and-place device 200 and the medical refrigerator 10 , the movable tray 100 is connected to the movable plate 240 . The sliding plate 220 is slidably connected to the frame 210. Since the first driving mechanism 230 is provided on the frame 210, the power output end of the first driving mechanism 230 is connected to the sliding plate 220. The first driving mechanism 230 drives the sliding plate 220 to slide relative to the frame 210, so that the movable plate 240 can slide the first motion stroke relative to the frame 210 along with the sliding plate 220. Since the moving component 252 is provided on the frame 210, the fixed plate 254 is connected to the power output end of the moving component 252, and the lifting component 256 is provided on the fixed plate 254, and the power output end of the lifting component 256 is plugged into the moving plate 240 when driving the moving plate 240, that is, when the moving plate 240 needs to be driven to slide relative to the sliding plate 220, first the power output end of the lifting component 256 is plugged into the moving plate 240, and then the moving component 252 drives the fixed plate 254 to move Because the lifting assembly 256 is mounted on the fixed plate 254 and the power output of the lifting assembly 256 is plugged into the movable plate 240, the fixed plate 254 drives the lifting assembly 256 and the movable plate 240 to move, thereby driving the movable plate 240 to slide relative to the sliding plate 220. This in turn causes the second drive mechanism 250 to drive the movable plate 240 to slide relative to the sliding plate 220. The second drive mechanism 250 drives the movable plate 240 to slide relative to the sliding plate 220 to a second motion stroke. Furthermore, since the first direction and the second direction are the same, the travel of the movable tray 100 is undoubtedly increased by the sliding stroke of the movable plate 240, increasing the travel of the movable tray 100 for the same length of the frame 210. This increases the travel of the pick-and-place device 200 to drive the movable tray 100, reduces the number of drive mechanisms, and solves the problem that a large-capacity medical refrigerator 10 cannot be further reduced in size. The above-mentioned pick-and-place device 200, equipped with the first drive mechanism 230 and the second drive mechanism 250, has a relatively compact overall structure and can flexibly adapt to limited working environments.

[0041] like Figure 6 As shown, in order for the first drive mechanism 230 to drive the sliding plate 220 to slide relative to the frame 210, in one embodiment, the first drive mechanism 230 includes a motor assembly 232, a gear 234, and a rack 236. The motor assembly 232 is disposed on the frame 210, and the gear 234 is sleeved on the power output shaft of the motor assembly 232. The rack 236 is connected to the sliding plate 220, and the rack 236 meshes with the gear 234, so that the power output end of the first drive mechanism 230 is connected to the sliding plate 220. When the motor assembly 232 drives the gear 234 to rotate, the gear 234 meshes with the rack 236 for transmission. Since the rack 236 is connected to the sliding plate 220 and the motor is disposed on the frame 210, the first drive mechanism 230 drives the sliding plate 220 to slide relative to the frame 210.

[0042] like Figure 4As shown, in one embodiment, the sliding plate 220 is slidably connected to one side of the frame 210. The movable plate 240 is slidably connected to the side of the sliding plate 220 facing away from the frame 210, so that the sliding movement of the sliding plate 220 relative to the frame 210 does not interfere with the sliding movement of the movable plate 240 relative to the sliding plate 220. In this embodiment, the frame 210, the sliding plate 220, and the movable plate 240 are arranged in parallel.

[0043] like Figure 5 As shown, to facilitate the sliding connection of the sliding plate 220 to the frame 210, in one embodiment, the pick-and-place device 200 further includes a guide rail 270 and a guide slider 280. The guide rail 270 is disposed on a side of the frame 210 adjacent to the sliding plate 220. The guide slider 280 is slidably coupled to the guide rail 270, and the guide slider 280 is coupled to the sliding plate 220, thereby enhancing the sliding connection of the sliding plate 220 to the frame 210. In this embodiment, the extension direction of the guide rail 270 is parallel to the extension direction of the rack 236, ensuring a smoother sliding movement of the sliding plate 220 relative to the frame 210 when the first drive mechanism 230 drives the sliding plate 220.

[0044] like Figure 4 As shown, to ensure precise sliding of the sliding plate 220 relative to the frame 210, the pick-and-place device 200 further includes a sensing plate 290, a first photoelectric switch 310, a second photoelectric switch 320, and a third photoelectric switch 370. The sensing plate 290 is disposed on the sliding plate 220. The first photoelectric switch 310, the second photoelectric switch 320, and the third photoelectric switch 370 are disposed side by side on the frame 210. The first photoelectric switch 310, the second photoelectric switch 320, and the third photoelectric switch 370 are all configured to detect the sensing plate 290. When the sensing plate 290 passes the first photoelectric switch 310, the first photoelectric switch 310 emits a first sensing signal indicating that the sensing plate 290 has been detected. When the sensing plate 290 passes the second photoelectric switch 320, the second photoelectric switch 320 emits a second sensing signal indicating that the sensing plate 290 has been detected. When the sensing plate 290 passes the third photoelectric switch 370, the third photoelectric switch 370 emits a third sensing signal indicating that the sensing plate 290 has been detected. The first photoelectric switch 310, the second photoelectric switch 320, and the third photoelectric switch 370 are all in communication with the control terminal of the first drive mechanism 230. In this embodiment, the position where the sensing plate 290 blocks the first photoelectric switch 310 is the original position of the sliding plate 220 relative to the frame 210. When the sensing plate 290 passes the second photoelectric switch 320 and the third photoelectric switch 370, the first drive mechanism 230 stops, allowing the first drive mechanism 230 to accurately drive the sliding plate 220 relative to the frame 210. When the control terminal of the first drive mechanism is in communication, the original position of the sliding plate 220 relative to the frame 210 is the starting point of the sliding movement of the sliding plate 220 relative to the frame 210, at which point the sensing plate blocks the first photoelectric switch.

[0045] In one embodiment, the second photoelectric switch 320 is further communicatively connected to the control terminal of the second drive mechanism 250. When the sensing sheet 290 passes the second photoelectric switch 320, the first drive mechanism 230 stops operating and the second drive mechanism 250 starts operating. Specifically, the power output terminal of the lifting assembly 256 is first connected to the movable plate 240, and then the movable plate 252 drives the fixed plate 254 to move. Since the lifting assembly 256 is disposed on the fixed plate 254 and the power output terminal of the lifting assembly 256 is connected to the movable plate 240, the fixed plate 254 drives the lifting assembly 256 and the movable plate 240 to move, thereby driving the movable plate 240 to slide relative to the sliding plate 220, and the second drive mechanism 250 then drives the movable plate 240 to slide relative to the sliding plate 220.

[0046] like Figure 4 As shown, in this embodiment, the mobile tray 100 is pluggably connected to the mobile plate 240. In one embodiment, the mobile plate 240 includes a plate body 242 and a positioning post 244 protruding from the side of the plate body 242 facing away from the sliding plate 220. The mobile tray 100 is provided with a positioning hole that is compatible with the positioning post 244, allowing the mobile tray 100 to be pluggably connected to the mobile plate 240. The plate body 242 is slidably connected to the sliding plate 220. The power output end of the lifting assembly 256 is used to plug into the plate body 242 when driving the mobile plate 240. When the movable plate 240 needs to be driven to slide relative to the sliding plate 220, first the power output end of the lifting component 256 is plugged into the plate body 242, and then the movable component 252 drives the fixed plate 254 to move. Since the lifting component 256 is provided on the fixed plate 254 and the power output end of the lifting component 256 is plugged into the plate body 242, the fixed plate 254 drives the lifting component 256 and the plate body 242 to move, thereby driving the plate body 242 to slide relative to the sliding plate 220, and then the second driving mechanism 250 drives the plate body 242 to slide relative to the sliding plate 220.

[0047] like Figure 4 As shown, in one embodiment, to allow the sliding plate 220 and the movable plate 240 to be disposed opposite each other and to make the structure of the pick-and-place device 200 more compact, the sliding plate 220 is provided with a first clearance groove 221. The lifting assembly 256 is connected to the movable plate 240 via the first clearance groove 221, allowing the sliding plate 220 and the movable plate 240 to be disposed opposite each other and to make the structure of the pick-and-place device 200 more compact.

[0048] like Figure 4As shown, in order to make the structure of the picking and placing device 200 more compact, in one embodiment, the frame 210 is provided with a second space avoidance groove 211 connected to the first space avoidance groove 221, and the lifting component 256 is connected to the movable plate 240 through the second space avoidance groove 211 and the first space avoidance groove 221 respectively, so that the frame 210, the sliding plate 220 and the movable plate 240 can be arranged opposite each other, thereby making the structure of the picking and placing device 200 more compact.

[0049] like Figure 4 As shown, in order to better position the lifting assembly 256 within the first and second clearance grooves 221, 211, and thereby make the structure of the pick-and-place device 200 more compact, in one embodiment, the first and second clearance grooves 221, 211 are positioned directly opposite each other, so that the lifting assembly 256 is better positioned within the first and second clearance grooves 221, 211, and thereby make the structure of the pick-and-place device 200 more compact. It is understood that in other embodiments, the first and second clearance grooves 221, 211 are partially staggered, and it is only necessary to ensure that the power output end of the lifting assembly 256 can be plugged into the movable plate 240 through the first and second clearance grooves 221, 211.

[0050] like Figure 4 As shown, to better enable the sliding plate 220 to slide and connect to the frame 210, in one embodiment, a sliding groove 223 is formed on a side of the sliding plate 220 facing away from the frame 210 and connected to the first escape groove 221. The movable plate 240 is located in the sliding groove 223 and is slidably connected to the sliding plate 220, allowing the movable plate 240 to slide smoothly with the sliding plate 220, thereby better enabling the sliding plate 220 to slide and connect to the frame 210.

[0051] like Figure 7 As shown, to avoid the problem of the power output end of the lifting assembly 256 being disconnected from the movable plate 240 during the sliding process of the movable plate 240, so that the movable assembly 252 can reliably drive the movable plate 240 to slide relative to the sliding plate 220, in one embodiment, the output direction of the power output end of the movable assembly 252 is perpendicular to the output direction of the power output end of the lifting assembly 256, so as to avoid the problem of the power output end of the lifting assembly 256 being disconnected from the movable plate 240 during the sliding process of the movable plate 240, so that the movable assembly 252 can reliably drive the movable plate 240 to slide relative to the sliding plate 220. It will be understood that in other embodiments, the output direction of the power output end of the movable assembly 252 and the output direction of the power output end of the lifting assembly 256 are not limited to being perpendicular to each other. In one embodiment, the angle between the output direction of the power output end of the movable assembly 252 and the output direction of the power output end of the lifting assembly 256 is 70° to 86°.

[0052] like Figure 7 and Figure 8 As shown, to facilitate the connection between the power output of the lifting assembly 256 and the movable plate 240, in one embodiment, the movable plate 240 is provided with a socket 244. The lifting assembly 256 includes a lifting cylinder 256a and a plug 256b. The lifting cylinder 256a is mounted on the fixed plate 254. One end of the plug 256b is connected to the power output post of the lifting cylinder 256a. The other end of the plug 256b is configured to be inserted into the socket 244 when the movable plate 240 is driven, thereby connecting the power output of the lifting assembly 256 to the movable plate 240.

[0053] like Figure 7 As shown, in one embodiment, the moving assembly 252 includes a translation module 252a and a module slider 252b. The translation module 252a is mounted on the frame 210. The power output direction of the translation module 252a is the same as the sliding direction of the moving plate 240. The module slider 252b is connected to the power output end of the translation module 252a, so that the translation module 252a drives the module slider 252b to move relative to the frame 210, thereby driving the moving plate 240 to slide relative to the sliding plate 220. In this embodiment, the module slider 252b is connected below the translation module 252a.

[0054] like Figure 8 As shown, in one embodiment, fixed plate 254 includes a first sub-plate 254a and a second sub-plate 254b connected to each other. Module slider 252b is connected to first sub-plate 254a. Lifting assembly 256 is mounted on second sub-plate 254b, so that both the power output of moving assembly 252 and lifting assembly 256 are connected to fixed plate 254. Furthermore, first sub-plate 254a and second sub-plate 254b are perpendicular to each other, and fixed plate 254 is L-shaped, ensuring that the movement of moving assembly 252 and lifting assembly 256 do not mechanically interfere with each other.

[0055] like Figure 7 and Figure 8As shown, in one embodiment, the pick-and-place device 200 further includes a first latch 330, a second latch 340, a first stopper 350, and a second stopper 360. The first latch 330 and the second latch 340 are arranged side by side on either side of the movable plate 240. The first stopper 350 and the second stopper 360 are both arranged on the sliding plate 220. The first stopper 350 is arranged corresponding to the first latch 330, and the second stopper 360 is arranged corresponding to the second latch 340. When the movable plate 240 slides in the forward direction relative to the sliding plate 220 to the limit position, the first latch 330 abuts against the first stopper 350, preventing the movable plate 240 from sliding further relative to the sliding plate 220, thereby acting as a mechanical stop. When the movable plate 240 slides in the reverse direction relative to the sliding plate 220 to the limit position, the second latch 340 abuts against the second stopper 360, preventing the movable plate 240 from sliding further relative to the sliding plate 220, thereby acting as a mechanical stop.

[0056] like Figure 8 and Figure 9 As shown, to ensure that the first latch 330 reliably contacts the first stopper 350, in one embodiment, a first protrusion 331 is provided on a surface of the first latch 330 adjacent to the first stopper 350. The first stopper 350 defines a first contact groove 351 corresponding to the first protrusion 331. When the movable plate 240 slides in the positive direction relative to the sliding plate 220 to the extreme position, the first protrusion 331 engages with the first contact groove 351, ensuring that the first latch 330 reliably contacts the first stopper 350.

[0057] like Figure 8 and Figure 10 As shown, to ensure that the second latch 340 reliably contacts the second stopper 360, in one embodiment, a second protrusion 341 is provided on a surface of the second latch 340 adjacent to the second stopper 360. The second stopper 360 defines a second contact groove 361 corresponding to the second protrusion 341. When the movable plate 240 slides in the opposite direction relative to the sliding plate 220 to the extreme position, the second protrusion 341 engages the second contact groove 361, ensuring that the second latch 340 reliably contacts the second stopper 360.

[0058] The pick-and-place mechanism operates as follows: Before the mechanism is activated, the movable plate 240 is at one end of the sliding plate 220, the sliding plate 220 is in the middle of the frame 210, and the sensor plate 290 blocks the first photoelectric switch 310. The first position is set to be close to the second photoelectric switch 320, and the second position is set to be close to the third photoelectric switch 370. When it is necessary to move from the first position to the second position, the movable plate 240 first slides relative to the sliding plate 220 to an end close to the first position; then the first driving mechanism 230 drives the sliding plate 220 to move toward the end close to the first position until the sensing sheet 290 blocks the second photoelectric switch 320, at which time the sliding plate 220 moves to the first position; then the movable tray is placed on the movable plate 240; then the first driving mechanism 230 drives the sliding plate 220 to move in the opposite direction until the sensing sheet blocks the first photoelectric switch 310, at which time the sliding plate is located in the middle position of the frame; then the lifting assembly 256 drives the movable plate 240 to slide on the sliding plate 220, so that the movable plate 240 moves from an end close to the first position to an end close to the second position, at which time the latch is locked; then the first driving mechanism 230 drives the sliding plate 220 to move in the direction close to the second position to the second position, at which time the sensing sheet 290 blocks the third photoelectric switch 370, and the sliding plate stops moving; finally, the movable tray is placed in the second position, and the pick-and-place device moves the movable tray from the first position to the second position.
