[0002] In the fields of biomedicine, histology and pathology, precoolers are mainly used to store wax blocks in tissue sections. These wax blocks are usually formed during the processing of biological samples and are used for microscopic observation after the preparation of pathological sections. It can keep the wax blocks under appropriate low temperature conditions to produce the corresponding hardness, ensuring that the tissue wax blocks can be sliced ​​continuously and completely during slicing. The existing tissue wax block precooling method can basically meet the daily use needs, but there are still some shortcomings that need to be improved.

[0042] An electric guide rail 9 is fixedly installed in the precooling cabinet 1, and a mechanical arm 10 is slidably installed on the electric guide rail 9. A gripper 25 is installed on the mechanical arm 10. The mechanical arm 10 can drive the gripper 25 to grab and place the wax block. The mechanical arm 10 is a prior art and is usually used to perform various industrial and non-industrial tasks. It will not be specifically described here. A wedge block 20 is fixedly installed on one side of the mechanical arm 10. A temperature display 4 is provided on the precooling cabinet 1 for displaying the temperature inside the precooling cabinet 1. At the same time, a temperature adjustment button is provided on the temperature display 4 for adjusting the temperature inside the precooling cabinet 1. A QR code 5 is provided outside the precooling cabinet 1.

The robot arm 10 is provided with a lighting lamp 11 and a QR code scanning lens. The lighting lamp 11 can assist the robot arm 10 to clearly and quickly scan the information of the clamped wax block, and transmit it to the slide marking machine through the network (the slide marking machine is used to provide the glass slide required for the wax block, and work with the precooling cabinet 1 to print the information of the wax block on the glass slide, take out the wax block, cut it and place it on the glass slide for microscopic observation); a switch 7 is installed on the precooling cabinet 1, and the switch 7 is used to control the overall power supply of the precooling cabinet 1, and can cut off the power when the precooling cabinet 1 is not in use.

[0043] The retrieval box 3 is also included, which is installed in the precooling cabinet 1 through a retrieval structure, and the retrieval structure is used to automatically eject the wax block taken out separately; the retrieval structure includes a fixed plate 16 fixedly installed in the precooling cabinet 1, and a plurality of springs 15 are fixedly installed on the fixed plate 16, and the retrieval box 3 is fixed to one end of the plurality of springs 15, and a locking rod 18 is fixedly installed on the retrieval box 3. The shape of the locking rod 18 is as shown in FIG. Figure 4 , vertical plates and fixed frames 12 are fixedly installed on both sides of the fixed plate 16, telescopic columns 13 are slidably installed in the two fixed frames 12, gear rods are fixedly installed on one side of the two telescopic columns 13, torsion springs 19 are fixedly installed on the two vertical plates, and a pawl 17 is installed between the two vertical plates for common rotation.

[0044] When the precooler 1 is not in use, the multiple springs 15 are in a non-stretched and non-compressed state. At this time, the taking box 3 is located outside the precooler 1 and slides on the receiving platform 2. The taking box 3 can seal the precooler 1 through its inner side to prevent the cold air inside the precooler 1 from leaking when taking the wax block. At the same time, a handle 6 is provided on one side of the taking box 3. When it is necessary to take the wax block, the handle 6 is held to push the taking box 3 onto the fixing plate 16. The multiple springs 15 are in a squeezed state. At the same time, the locking rod 18 is engaged with the pawl 17, so that the taking box 3 will not be pushed out under the elastic force of the spring 15. The setting of multiple springs 15 can ensure the stable sliding of the taking box 3. At this time, the outer side of the taking box 3 is also sealed with the pre-cooling cabinet 1; when the wax block is grabbed by the gripper 25 to the top of the taking box 3, the gripper 25 is opened at this time, and the gripper 25 will be against the telescopic columns 13 on both sides. The upper ends of the two telescopic columns 13 are set at a certain inclination, which can make the two telescopic columns 13 quickly move downward The two telescopic columns 13 drive the two gear rods to move downward, and the two gears 14 rotate accordingly, driving the pawl 17 to rotate at this time, and the locking rod 18 will not be engaged, and the take-up box 3 is unlocked, and the take-up box 3 is driven to pop out of the precooling cabinet 1 under the elastic force of the spring 15, and such a cycle is circulated, so that the wax blocks can be taken out separately and in sequence each time, and the sealing of the precooling cabinet 1 can be ensured, and the remaining wax blocks are prevented from being polluted by the outside air; at the same time, the distance between the two telescopic columns 13 can ensure that the gripper 25 will release the wax block and then abut against the telescopic column 13, so that the wax block can be accurately placed in the take-up box 3; a pressure gauge is set on the fixed plate 16, and the pressure gauge is used to measure the elastic force of the spring 15, and the side pressure gauge is connected with the electric guide rail 9 and the mechanical arm 10 by program, when the spring 15 receives the extrusion force (when the personnel push the take-up box 3), the electric guide rail 9 drives the mechanical arm 10 to start grabbing the wax block, so as to realize the automatic removal of the wax block.

[0045] See also Figure 5-Figure 8 , also includes a mounting groove 28, which is opened in the precooling cabinet 1; a square plate 21, which is fixedly installed in the mounting groove 28; a replacement structure, which is installed on the square plate 21 and connected to the conveying structure, and the replacement structure is used to push out the placement box 8 after taking out the wax block and replace it with the next group, so as to carry out the uninterrupted wax block taking process; the replacement structure includes a slide plate 1 33 and a slide plate 2 34 slidably installed on the square plate 21, a turntable is rotatably installed on the slide plate 1 33, a spring 2 53 is installed between the turntable and the slide plate 2 34, and a threaded shaft 45 is fixedly installed on the side of the turntable away from the slide plate 2 34, and the threaded shaft 45 is connected to the mounting groove A torsion spring 26 is fixedly installed between the two slides 28, a fixed column 52 is fixedly installed on the side of the slide 1 33 away from the slide 2 34, a stopper 54 is fixedly installed on the fixed column 52, a push rod 36 is rotatably installed on the fixed column 52, a torsion spring four is arranged between the push rod 36 and the fixed column 52, when the wedge block 20 abuts against the push rod 36 and moves downward relatively, it can drive the push rod 36 to rotate downward, when the wedge block 20 abuts against the push rod 36 and moves upward relatively, at this time, the push rod 36 is pushed to move under the setting of the stopper 54, so that the push rod 36 can only rotate downward, and rebound to a horizontal state under the setting of the torsion spring four.

[0046] When the robot arm 10 drives the gripper 25 to clamp the last wax block close to the push rod 36, the robot arm 10 moves downward to drive the wedge block 20 to abut against the push rod 36, and the push rod 36 rotates downward, and no horizontal driving force is generated on the fixed column 52. When the robot arm 10 moves upward to drive the wedge block 20 to abut against the push rod 36, the push rod 36 will not bend upward under the action of the stop block 54. At this time, a horizontal driving force is generated on the fixed column 52, and the slide plate 33 is squeezed.

[0047] See also Figure 8-Figure 10 The threaded shaft 45 is provided with a lifting mechanism for lifting the placement box 8 and a pushing mechanism for pushing out the placement box 8. A guide rod 35 is fixedly installed on the lower surface of the square plate 21. The threaded shaft 45 is provided with a thread, and the thread is arranged on the threaded shaft 45 for a circle. The guide rod 35 is slidably arranged in the thread. The lifting mechanism includes a rotating rod 31 fixedly installed on one of the pulleys 24, and the rotating rod 31 is rotatably arranged in the precooling cabinet 1. Two one-way bearings 29 are rotatably arranged in the installation groove 28. The two one-way bearings 29 A fixed shaft 46 is provided inside the rotating sleeve, one of which is fixedly mounted with a pulley 2 on one of the fixed shafts 46 and the rotating rod 31, and a conveyor belt 30 is provided between the two pulleys 2 for common rotation. A telescopic rod 47 is fixedly mounted on one end of the two fixed shafts 46, and one end of the two telescopic rods 47 is fixedly set between the slide plate 2 34, and a gear 3 49 is fixedly mounted on one end of one of the telescopic rods 47, and an incomplete gear 1 37 is fixedly mounted on the threaded shaft 45, and the gear 3 49 is meshed with the incomplete gear 1 37 for use.

[0048] The pushing mechanism includes a gear 2 39 fixedly mounted on another telescopic rod 47, an incomplete gear 2 38 fixedly mounted on the threaded shaft 45, and the incomplete gear 2 38 is used in meshing with the gear 2 39, two torsion springs 3 32 are fixedly mounted in the precooling cabinet 1, and threaded sleeves 42 are fixedly mounted on the two torsion springs 32, two connecting frames 44 are fixedly mounted in the precooling cabinet 1, threaded rods 43 are rotatably mounted on the two connecting frames 44, and the threaded rods 43 are threadedly mounted in the corresponding threaded sleeves 42, one of the threaded sleeves 42 and the other fixed shaft 46 are fixedly mounted with pulleys 3, and a conveyor belt 48 is provided between the two pulleys 3 for rotating together, and pulleys 4 are fixedly mounted on the two threaded sleeves 42, and a conveyor belt 2 27 is provided between the two pulleys 4 for rotating together, the setting angle of the teeth on the incomplete gear 1 37 is 270°, and the setting angle of the teeth on the incomplete gear 2 38 is 180° (refer to Fig.10 ), so that when the threaded shaft 45 rotates, it first drives the incomplete gear 2 38 to mesh with the gear 2 39 and rotates. After rotating for a period of time, the threaded shaft 45 rotates to drive the incomplete gear 1 37 to mesh with the gear 3 49, driving the placement box 8 to be pushed out first and then rise.

[0049] The stabilizing structure is installed on the replacement structure to stabilize the state of the wax block when it is clamped. The stabilizing structure includes a trigger rod 40 fixedly installed on one side of the slide 1 33, and the trigger rod 40 slides through the slide 2 34. A fixing frame 50 is fixedly installed on the connecting frame 44, and a locking rod 41 is rotatably installed on the fixing frame 50. A limiting rod 51 is fixedly installed on each placement box 8. The locking rod 41 relatively locks the limiting rod 51 under the setting of the fixing frame 50, so as to ensure the stability of the placement box 8 when clamping the wax block; the setting of the fixing frame 50 allows the locking rod 41 to only rotate clockwise (to Fig.10 For example), the limiting rod 51 is locked in the fixing frame 50. When the placement box 8 tends to slide out of the precooling cabinet 1, the limiting rod 51 will move outward (toward the direction of the locking rod 41). At this time, the locking rod 41 cannot rotate counterclockwise under the setting of the fixing frame 50, which can ensure that the placement box 8 will not slide in the precooling cabinet 1 and ensure the stability of the wax block when it is clamped.

[0050] When the gripper 25 takes the last wax block, the wedge block 20 is driven to move upward, and the wedge block 20 moves upward to squeeze the push rod 36. The push rod 36 pushes the slide plate 1 33 to the position of the slide plate 2 34 through the fixed column 52 to squeeze the spring 2 53. The slide plate 1 33 drives the trigger rod 40 to press the locking rod 41. The locking rod 41 is pressed on the fixed frame 50 and rotates, driving the lower end of the locking rod 41 to rotate to the top of the limit rod 51. At this time, the limit rod 51 and the locking rod 41 on the topmost box 8 are unlocked. Immediately after the slide plate 2 34 moves, the threaded shaft 45 rotates under the action of the guide rod 35. The rotation of the threaded shaft 45 drives the incomplete gear 2 38 and the incomplete gear 1 37 to rotate at the same time, but at this time The incomplete gear 1 37 is not meshed with the gear 2 39, and the incomplete gear 2 38 drives the gear 2 39 to rotate. The rotation of the gear 2 39 drives the fixed shaft 46 to rotate through the corresponding telescopic rod 47. The fixed shaft 46 drives the threaded sleeve 42 connected thereto to rotate through the conveyor belt 48. The threaded sleeve 42 drives another threaded sleeve 42 to rotate at the same time through the conveyor belt 2 27. The rotation of the two threaded sleeves 42 drives the two threaded rods 43 to move toward the placement box 8. The two threaded rods 43 push the top placement box 8 (the setting of the two threaded rods 43 can make the top placement box 8 be pushed stably and smoothly to prevent it from tilting), and the placement box 8 is placed on the receiving table 2 outside the pre-cooling cabinet 1. The two torsion springs 32 are twisted at this time. After the placement box 8 is pushed out for a period of time, the incomplete gear 37 starts to mesh with the gear 3 49. The gear 3 49 drives the conveyor belt 3 30 to rotate through the corresponding telescopic rod 47 and the fixed shaft 46. The rotation of the conveyor belt 30 drives the rotating rod 31 to rotate. The rotation of the rotating rod 31 rotates through the corresponding pulley 1 24. The rotation of the pulley 1 24 drives the multiple placement rods 23 to rotate through the conveyor belt 1 22 connected thereto and the remaining multiple conveyor belts 1 22 (the conveyor belts 1 22 on both sides rotate in the direction away from each other), driving the placement box 8 below to rise upward, and then the top placement box 8 is completely pushed onto the receiving platform 2 without interfering with the placement box 8 below. When the lower placement box 8 is about to rise to the vertical height of a placement box 8 (the second placement box 8 from the top rises to the position of the top placement box 8, the third placement box 8 from the top rises to the position of the second placement box 8, and so on), the incomplete gear 2 38 rotates and no longer engages with the gear 2 39, and the two torsion springs 32 drive the two threaded sleeves 42 to reverse. At this time, the two threaded rods 43 rotate back into the corresponding threaded sleeves 42, and will not affect the rise of the lower placement box 8, and are again located on the side of the top placement box 8; at the same time, the limit rod 51 on the top placement box 8 is locked again between the locking rod 41 and the fixing frame 50, which can ensure the stability of the wax block when it is clamped.

[0051] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
