Description

Technical Field

[0001] The present invention relates to the technical field of biological sample freezing and storage equipment, and particularly to an equipment for batch extraction of freezing boxes. Background Art

[0002] Biological samples are usually stored in freezing tubes, and then several freezing tubes are centrally stored in a freezing box, and then several freezing boxes are centrally stored on a freezing rack to achieve simultaneous preservation of multiple groups of biological samples and facilitate classification management of various biological samples. The existing extraction of freezing boxes mainly uses transfer devices such as robotic arms to clamp and remove the freezing boxes from the freezing rack. However, the existing robotic arm extraction device for freezing boxes can only clamp and remove one freezing box from the freezing rack each time. Therefore, when several freezing boxes need to be extracted from the freezing rack at one time in practice, it is obvious that the efficiency of batch extraction of freezing boxes by the existing robotic arm is not high. Summary of the Invention

[0003] The technical problem solved by the present invention is that the existing robotic arm has low efficiency in the process of batch extraction of freezing boxes.

[0004] An equipment for batch extraction of freezing boxes provided by the present invention includes a fixed disk, a fixed rod, a moving device, a storage device, a telescopic rod, a clamping device, and a fixing device. The storage device is installed on the left part of the moving device, the top surface of the right part is connected to the fixed disk through the fixed rod, the bottom surface of the right part is connected to the clamping device through the telescopic rod, and the clamping device is connected to the fixing device.

[0005] By setting up an equipment for batch extraction of freezing boxes including a moving device, a storage device, a clamping device, and a fixing device, the present invention can extract several freezing boxes from the freezing rack at one time as needed, which can greatly improve the efficiency of batch extraction of freezing boxes. Specifically, first, move the equipment to a position as close as possible to the freezing rack through the fixed disk and the fixed rod. Secondly, place several freezing boxes clamped from the freezing rack on the storage device one by one through the clamping device, the storage device, and the fixing device. When all the required number of freezing boxes are transferred to the storage device, the equipment can be moved to a position convenient for taking out the freezing boxes through the fixed disk and the fixed rod, and several batch-extracted freezing boxes can be taken down from the storage device one by one manually.

[0006] Furthermore, the outer shape of the storage device is a rectangular frame, and the rectangular frame includes a top plate and a bottom plate. Four vertical columns are arranged vertically between the four corners at the bottom of the top plate and the four corners at the top of the bottom plate. Two columns of several layers of fixing plate card slots are evenly distributed vertically and symmetrically arranged on the inner sides of the two left vertical columns, and two columns of several layers of fixing plate moving guide support card slots are evenly distributed vertically and symmetrically arranged on the inner sides of the two right vertical columns.

[0007] Further, the two fixing plate card slots and the two fixing plate moving guiding and supporting card slots on each layer are jointly used to support the fixing plate. Control rod fixing blocks are arranged on the outer sides of the two vertical columns on the right side. Control rod mounting holes are formed in the middle of the two control rod fixing blocks, and the control rod mounting holes are used to mount control rods.

[0008] Further, the moving device includes a clamping assembly. The clamping assembly includes a clamping member and a fixing member. The fixing rod is installed at the top of the clamping member, and two fixing member moving tracks are arranged at the bottom. Fixing member limiting ridges are arranged on the inner side surfaces of the two fixing member moving tracks. The fixing member is a rectangular fixing member, and fixing member limiting grooves are arranged on the front and rear sides of the rectangular fixing member. The two fixing member limiting grooves are matched with and fixedly connected to the two fixing member limiting ridges.

[0009] Further, four vertical column moving guiding holes are formed on the left side of the fixing member. The four vertical column moving guiding holes are matched with the four vertical columns. Nested telescopic control rods are installed in the middle of the front and rear sides of the bottom of the fixing member, and a telescopic rod is installed on the right side of the bottom. A T-shaped hydraulic channel is arranged in the inner cavity of the fixing member. Control rod hydraulic cavities are arranged below the two left ports at the two ends of the T-shaped hydraulic channel, and a telescopic rod hydraulic cavity is arranged below the right port. The two nested telescopic control rods are installed at the two control rod hydraulic cavities, and the telescopic rod is installed at the telescopic rod hydraulic cavity.

[0010] When the telescopic rod expands and contracts, the liquid inside the telescopic rod hydraulic cavity can be squeezed. The squeezed liquid enters the two control rod hydraulic cavities through the T-shaped hydraulic channel and squeezes the nested telescopic control rods, thereby driving the nested telescopic control rods to perform telescopic motion. Through the telescopic motion of the nested telescopic control rods, the storage device is driven to perform lifting motion on the moving device.

[0011] Further, the clamping device includes a jaw slider, an upper connecting groove of a fixed connecting block, a rectangular sliding groove, and a clamping assembly. The jaw slider is a rectangular jaw slider. The top surface of the right part of the rectangular jaw slider is connected to the moving device through the telescopic rod, and the left part extends into the storage device. A telescopic control member is arranged at the top of the telescopic rod. Two upper connecting grooves of the fixed connecting block are arranged in the middle of the front and rear side surfaces of the jaw slider, and the rectangular sliding groove is arranged at the bottom. The clamping assembly is installed in the rectangular sliding groove.

[0012] Furthermore, the clamping device also includes a telescopic clamping claw, a U-shaped pushing rod and a pushing block. The clamping assembly adopts a rectangular clamping assembly. A sliding drive member is provided at the connection between the rectangular clamping assembly and the rectangular sliding groove. The telescopic clamping claw is installed at one end of the clamping assembly, and the U-shaped pushing rod is installed at the other end. The free end of the U-shaped pushing rod is equipped with the pushing block.

[0013] The U-shaped pushing rod can simultaneously realize the rectangular clamping assembly to perform linear reciprocating motion on the rectangular sliding groove and the pushing block to perform synchronous linear reciprocating motion. When the rectangular clamping assembly extends forward to clamp the frozen box, the pushing block synchronously pushes the fixed plate through the pushing mouth and moves the fixed plate from the ejection mouth to the two fixed plate slots and the two fixed plate movement guide support slots on any layer of the rectangular frame to support the fixed plate. Then the rectangular clamping assembly retreats to the fixed plate position with the clamped frozen box and places the frozen box on the fixed plate.

[0014] Furthermore, the fixing device includes a fixing plate accommodating shell, a fixing plate, an elastic member, a push port, an ejection port and a fixed connecting block. The fixing plate accommodating shell has the shape of a six-sided closed shell. The push port and the ejection port are respectively opened on the upper part of two side surfaces of the six-sided closed shell, and two lower connecting grooves of the fixed connecting blocks are respectively opened on the upper part of the other two side surfaces. The elastic member is installed at the bottom of the internal cavity of the six-sided closed shell, and several fixing plates are placed between the top of the elastic member and the top of the internal cavity of the six-sided closed shell.

[0015] Furthermore, the fixed connection block is installed between the two upper connection grooves of the fixed connection blocks and the two lower connection grooves of the fixed connection blocks.

[0016] Furthermore, the ejection port is arranged on the right side of the two fixed plate movable guide support slots, and the right side of the push port is in contact with the push block. BRIEF DESCRIPTION OF THE DRAWINGS

The clamping device 3 is connected to the fixing device 4.

[0036] In this embodiment, by setting up an apparatus for batch extraction of cryoboxes including a moving device 1, a storage device 2, a clamping device 3, and a fixing device 4, several cryoboxes 6 can be extracted from a cryobox rack 5 at one time as needed, which can greatly improve the operation efficiency of batch extraction of cryoboxes 6. Specifically, first, the apparatus is moved to a position as close as possible to the cryobox rack 5 through the fixed disk 13 and the fixed rod 12. Secondly, several cryoboxes 6 clamped from the cryobox rack 5 are placed on the storage device 2 one by one through the clamping device 3, the storage device 2, and the fixing device 4. When all the required number of cryoboxes 6 are transferred to the storage device 2, the apparatus can be moved to a position convenient for taking out the cryoboxes 6 through the fixed disk 13 and the fixed rod 12, and several cryoboxes 6 extracted in batch are taken off from the storage device 2 manually.

[0037] Optionally, as Figure 1 、 Figure 2 、 Figure 7 and Figure 8 shown, the outer shape of the storage device 2 is a rectangular frame. The rectangular frame includes a top plate and a bottom plate. Four vertical columns are arranged vertically between the four corners at the bottom of the top plate and the four corners at the top of the bottom plate. Two columns of several layers of fixing plate slots 21 are evenly distributed along the vertical direction on the inner sides of the two left vertical columns and are arranged symmetrically in pairs. Two columns of several layers of fixing plate moving guide support slots are evenly distributed along the vertical direction on the inner sides of the two right vertical columns and are arranged symmetrically in pairs.

[0038] Optionally, as Figure 2 、Figures 4 - 8 As shown, the two fixing plate slots 21 and the two fixing plate moving guiding and supporting slots of each layer are jointly used to support the fixing plate 43. Control rod fixing blocks 22 are provided on the outer sides of the two vertical columns on the right. Control rod mounting holes are opened in the middles of the two control rod fixing blocks 22, and the control rod mounting holes are used to mount the control rod 142.

[0039] Optionally, as Figures 1 - 6 、 Figure 8 shown, the moving device 1 includes a clamping assembly. The clamping assembly includes a clamping member 11 and a fixing member 14. The fixing rod 12 is installed at the top of the clamping member 11. Two fixing member moving tracks are provided at the bottom. Fixing member limiting ridges 111 are provided on the inner sides of the two fixing member moving tracks. The fixing member 14 is a rectangular fixing member. Fixing member limiting grooves 141 are provided on the front and rear sides of the rectangular fixing member. The two fixing member limiting grooves 141 are matched with the two fixing member limiting ridges 111 and are fixedly connected.

[0040] Optionally, as Figure 2 、 Figures 4 - 6 、 Figure 8 shown, four vertical column moving guiding holes 143 are opened on the left side of the fixing member 14. The four vertical column moving guiding holes 143 are matched with the four vertical columns. Nested telescopic control rods 142 are installed in the middles of the front and rear sides at the bottom of the fixing member 14. A telescopic rod 311 is installed on the right side at the bottom. A T-shaped hydraulic channel 144 is provided in the inner cavity of the fixing member 14. Control rod hydraulic cavities 146 are provided below the two left ports of the T-shaped hydraulic channel 144. A telescopic rod hydraulic cavity 145 is provided below the right port. The two nested telescopic control rods 142 are installed at the two control rod hydraulic cavities 146. The telescopic rod 311 is installed at the telescopic rod hydraulic cavity 145.

[0041] In this embodiment, when the telescopic rod 311 expands and contracts, the liquid inside the telescopic rod hydraulic cavity 145 can be squeezed. The squeezed liquid enters the two control rod hydraulic cavities 146 through the T-shaped hydraulic channel 144 and squeezes the nested telescopic control rods 142, thereby driving the nested telescopic control rods 142 to perform telescopic motion. Through the telescopic motion of the nested telescopic control rods 142, the storage device 2 is driven to perform lifting motion on the moving device 1.

[0042] Optionally, as Figure 1 、 Figures 9 - 11As shown, the clamping device 3 includes a jaw slider 31, an upper connecting groove 312 of a fixed connecting block, a rectangular sliding groove 313, and a clamping assembly 32. The jaw slider 31 is a rectangular jaw slider. The top surface of the right part of the rectangular jaw slider is connected to the moving device 1 through the telescopic rod 311, and the left part extends into the storage device 2. A telescopic control member is provided at the top of the telescopic rod 311. Two upper connecting grooves 312 of the fixed connecting block are provided in the middle of the front and rear side surfaces of the jaw slider 31, and the rectangular sliding groove 313 is provided at the bottom. The clamping assembly 32 is installed in the rectangular sliding groove 313.

[0043] Optionally, as Figure 1 , Figure 10 and Figure 11 shown, the clamping device 3 further includes a telescopic jaw 321, a U-shaped push rod 33, and a push block 331. The clamping assembly 32 is a rectangular clamping assembly. A sliding driving member is provided at the connection between the rectangular clamping assembly and the rectangular sliding groove 313. One end of the clamping assembly 32 is equipped with the telescopic jaw 321, and the other end is equipped with the U-shaped push rod 33. The free end of the U-shaped push rod 33 is equipped with the push block 331.

[0044] The U-shaped push rod 33 can simultaneously achieve the linear reciprocating motion of the rectangular clamping assembly on the rectangular sliding groove 313 and the synchronous linear reciprocating motion of the push block 331. When the rectangular clamping assembly extends forward to clamp the cryopreservation box 6, the push block 331 synchronously pushes the fixed plate 43 through the push port 412 and makes the fixed plate 43 move from the ejection port 413 to any layer of the two fixed plate card slots 21 and the two fixed plate moving guiding and supporting card slots on the rectangular frame so as to support the fixed plate 43. Subsequently, the rectangular clamping assembly returns with the clamped cryopreservation box 6 to the position of the fixed plate 43 and places the cryopreservation box 6 on the fixed plate 43.

[0045] Optionally, as Figure 1 , Figure 2 , Figures 12 - 14 shown, the fixing device 4 includes a fixing plate accommodating housing 41, a fixing plate 43, an elastic member 411, a push port 412, an ejection port 413, and a fixed connecting block 42. The fixing plate accommodating housing 41 has an outer shape of a six-sided closed housing. The push port 412 and the ejection port 413 are respectively opened on the upper parts of the two side surfaces of the six-sided closed housing, and two lower connecting grooves of the fixed connecting block are respectively opened on the upper parts of the other two side surfaces. The elastic member 411 is installed at the bottom of the internal cavity of the six-sided closed housing, and several fixing plates 43 are placed between the top of the elastic member 411 and the top of the internal cavity of the six-sided closed housing.

[0046] Optionally, as Figure 2 , Figure 9 and Figure 11As shown, the fixed connection block 42 is installed between the upper connection grooves 312 of the two fixed connection blocks and the lower connection grooves of the two fixed connection blocks.

[0047] Optionally, as Figure 2 , Figures 12 - 14 shown, the ejection port 413 is arranged on the right side of the moving guide support grooves of the two fixed plates, and the right side of the pushing port 412 is in contact with the pushing block 331.

[0048] Basic principle of the present invention: The moving device 1 moves to a position as close as possible to the cryopreservation rack 5 through a linear reciprocating movement component (not shown in the figure) connected above the fixed disk 13. The telescopic rod 311 drives the jaw slider 31 to extend. When the telescopic rod 311 extends, through the T-shaped hydraulic channel 144 inside the jaw slider 31, it drives the control rod 142 connected to the other end of the hydraulic channel 144 to contract, and drives the storage device 2 to move upward through the control rod 142. Subsequently, the telescopic jaws 321 on the clamping component 32 at the bottom of the jaw slider 31 extend to clamp the cryopreservation box 6 on the cryopreservation rack 5.

[0049] When the rectangular clamping component extends forward to clamp the cryopreservation box 6, the pushing block 331 synchronously pushes the fixed plate 43 through the pushing port 412 and makes the fixed plate 43 move from the ejection port 413 to the two fixed plate slots 21 and the two fixed plate moving guide support slots on any layer of the rectangular frame to support the fixed plate 43. Subsequently, the clamping component 32 moves along the rectangular sliding groove 313 of the jaw slider 31 to the other end (the end far from the cryopreservation rack 5), and the pushing rod 33 retracts synchronously with the clamping component 32. At this time, the pushing block 331 also synchronously exits from the pushing port 412 on the fixed plate accommodating housing 41. Another fixed plate 43 is pushed by the elastic member 411 at the bottom of the inner cavity of the fixed plate accommodating housing 41 to the top position of the inner cavity of the fixed plate accommodating housing 41. Then, the rectangular clamping component brings the clamped cryopreservation box 6 back to the support position of the fixed plate 43 and places the cryopreservation box 6 on the fixed plate 43.

[0050] Subsequently, the telescopic rod 311 contracts and drives the jaw slider 31 to move upward. During the upward movement of the jaw slider 31, through the T-shaped hydraulic channel 144 inside the jaw slider 31, it drives the control rod 142 connected to the other end of the hydraulic channel 144 to extend, and drives the storage device 2 to move downward by a distance greater than the height of the cryopreservation box, so that the cryopreservation box 6 just placed in the storage device 2 also moves downward by a distance greater than the height of the cryopreservation box. Subsequently, the clamping component 32 resets.

[0051] Repeat the above steps to achieve batch extraction of a number of cryoboxes 6. After the required number of cryoboxes 6 are extracted, the equipment can be moved to a position convenient for removing the cryoboxes 6 through the moving device 1. At this time, the staff can take out this batch of cryoboxes 6 and the fixing plate 43 together, and then place the fixing plates 43 back into the fixing plate accommodating housing 41 one by one for subsequent batch extraction operations of the cryoboxes 6.

[0052] Although the present invention is disclosed as the above preferred embodiments, the present invention is not limited thereto. Those skilled in the art can make various permutations and combinations of the above preferred embodiments without departing from the spirit and scope of the present invention and form a complete technical solution.
