[0037] The cutting part 1 cuts the wax block into wax flakes; a conductive component 16 is provided obliquely on the cutting part 1; the collecting part 2 is located on one side of the cutting part 1; the end of the conductive component 16 away from the cutting component 15 abuts against the collecting part 2; the wax flakes slide along the conductive component 16 into the interior of the collecting part 2; the interior of the collecting part 2 is filled with liquid.

[0038] The scooping unit 3 includes a robotic arm and a working arm 35. The robotic arm has at least two pivot joints. The working arm 35 is rotatably connected to the robotic arm. A guide camera 353, a gripper 36, and a stopper 356 are provided at the end of the working arm 35 away from the robotic arm. The gripper 36 is hingedly connected to the working arm 35. The guide camera 353 and the stopper 356 are both fixedly connected to the working arm 35. The working arm 35 is equipped with a toggle motor 354, which drives the gripper 36 to rotate.

When retrieving the slice, the stop plate 356 is inserted around the slice to define the relative position of the slice and the glass slide 6. After retrieving the slice, the slice can be placed in the predetermined position on the glass slide 6. The purpose of this design is:

[0040] 1. Achieve standardized production and produce finished products with the same standards when producing tissue samples on a large scale.

[0041] 2. It is convenient for the pathology department to use, and avoid the structural differences of the immunohistochemistry automatic staining machine caused by inappropriate slide scooping position, which may result in the staining agent not covering the slice and making the slice unable to be stained.

[0042] In some embodiments of the present application, a telescopic structure is provided between the working arm 35 and the limiting frame 351 to adjust the distance between the working arm 35 and the limiting frame 351, thereby adjusting the position of the slice on the slide 6. Different fully automatic immunohistochemical staining machines stain different tissue samples; some require the slice to be located in the center of the slide 6, while others require it to be located at one end. By adjusting the distance between the working arm 35 and the limiting frame 351, the position of the slice on the slide 6 can be adjusted, thereby matching different fully automatic immunohistochemical staining machines, achieving personalized customization of the finished product, and meeting the needs of enterprises for mass production.

[0043] Specifically, a toggle wheel 355 is provided on the output shaft of the toggle motor 354, and a driven wheel 37 is provided on the clamper 36. The toggle wheel 355 drives the driven wheel 37 to rotate, so that the toggle motor 354 drives the clamper 36 to rotate.

[0044] Preferably, the driving wheel 355 and the driven wheel 37 are both gears, and the driving wheel 355 is meshed with the driven wheel 37 .

[0045] In an embodiment of the present application, the driving wheel 355 and the driven wheel 37 are connected via a transmission member 38 .

[0046] Specifically, the driving wheel 355 and the driven wheel 37 are both sprockets, and the transmission member 38 is a chain.

[0047] The driving wheel 355 and the driven wheel 37 are both pulleys, and the transmission member 38 is a belt.

[0048] The guide camera 353 determines the position of the wax sheet by the difference in light reflection between the liquid surface and the wax sheet.

[0049] During use, the wax block is placed on the cutting part 1, and the cutting part 1 cuts the wax block into wax slices, and then the wax slices slide into the interior of the collecting part 2 along the conductive component 16 and float on the liquid surface; the robotic arm drives the working arm 35 to insert the glass slide 6 on the clamp 36 into the liquid, and then guides the camera 353 to find the position of the wax slice, and the robotic arm drives the glass slide 6 to the bottom of the wax slice; the robotic arm drives the working arm 35 to continue to sink into the liquid surface, so that the limit piece 356 surrounds the wax slice, and then the motor 354 is turned to drive the clamp 36 to rotate, so that the glass slide 6 rotates and gradually approaches the liquid surface, and finally drives the glass slide 6 to pick up the wax slice, realizing automatic slice catching.

[0050] Specifically, the clamp 36 is a small electric clamp. A groove matching the slide 6 is provided on the clamping surface of the electric clamp so that the electric clamp can clamp the slide 6.

[0051] like Figure 1 As shown, the apparatus also includes a slide placement area 4 and a finished product placement area 5, which are located on either side of the collection portion 2. During use, a slide 6 is placed in the slide placement area 4. The robotic arm drives the gripper 36 to move to the slide placement area 4 and grip the slide 6 within the slide placement area 4. The robotic arm then drives the slide 6 to retrieve a wax sheet and places the waxed slide 6 within the finished product placement area 5.

[0052] Specifically, the glass slide placement area 4 includes a first bracket; a plurality of glass slide 6 mounting grooves are provided inside the first bracket; and the plurality of glass slide 6 mounting grooves are regularly arrayed inside the first bracket.

[0053] Preferably, the glass slide 6 mounting groove is obliquely arranged inside the first bracket to facilitate the clamper 36 to take the glass slide 6.

[0054] Specifically, the finished product placement area 5 includes a second bracket; a plurality of finished product installation slots are provided inside the second bracket; and the plurality of finished product installation slots are regularly arrayed inside the second bracket.

[0055] Preferably, the finished product mounting groove is obliquely arranged inside the second bracket to facilitate the holder 36 to place the finished product.

[0056] like Figure 2 As shown, the collecting portion 2 includes a receiving chamber 21 , which is a regular container with an opening. A slide rail 22 is provided on the outer wall of the receiving chamber 21 ; the robotic arm moves along the slide rail 22 .

[0057] Specifically, the storage cavity 21 is a circular cavity, and the slide rail 22 is an annular track, so that the robot arm can move around the storage cavity 21 via the slide rail 22 , so that the scooping part 3 can scoop the wax flakes at any position of the storage cavity 21 .

[0058] like Figure 2 As shown, a lifting assembly 13 and a moving assembly 14 are provided on the side wall of the cutting portion 1; a mounting member 132 is provided on the lifting assembly 13; a cutting assembly 15 is provided on the moving assembly 14; one end of the conducting assembly 16 abuts against the cutting assembly 15; the lifting assembly 13 drives the mounting member 132 to perform reciprocating linear motion in a direction parallel to the cutting assembly 15; and the moving assembly 14 drives the cutting assembly 15 to perform reciprocating linear motion in a direction perpendicular to the motion path of the lifting assembly 13.

[0059] Specifically, the cutting assembly 15 is arranged horizontally, the lifting assembly 13 drives the mounting member 132 to perform reciprocating linear motion in the vertical direction, and the motion assembly 14 drives the cutting assembly 15 to perform reciprocating linear motion in the horizontal direction. During use, the wax block is fixed to the mounting member 132, the lifting assembly 13 drives the wax block downward, and the cutting assembly 15 cuts a wax sheet from the wax block. The lifting assembly 13 then drives the wax block upward and disengages from the cutting assembly 15, and the motion assembly 14 drives the cutting assembly 15 toward the wax block. The lifting assembly 13 then drives the wax block downward again, and the cutting assembly 15 cuts another wax sheet from the wax block. This reciprocating process continues until the cutting unit 1 cuts the wax block into wax sheets. Each time the cutting assembly 15 cuts the wax block, the motion assembly 14 drives the cutting assembly 15 toward the wax block. Therefore, the distance the cutting assembly 15 moves each time is the thickness of the wax sheet.

[0060] Preferably, a clamping claw for mounting the wax block is provided on the mounting member 132. The clamping claw firmly fixes the wax block on the mounting member 132 to prevent the wax block from being offset and causing the wax slices cut by the cutting assembly 15 to have different thicknesses.

[0061] like Figure 3 As shown, the cutting assembly 15 includes a housing 11; a controller 12 is provided on the side wall of the housing 11; the controller 12 can adjust the movement distance of the moving assembly 14 each time, that is, the thickness of the wax sheet.

[0062] Specifically, the controller 12 includes a display and buttons.

[0063] Furthermore, the housing 11 includes a processor, which is used to determine the position of the wax sheet inside the storage cavity 21 through the guide camera 353, and then drive the scooping part 3 to move so that the glass slide 6 can scoop the wax sheet.

[0064] like Figure 4 、 5 As shown, a buffer water tank 17 is provided on the housing 11. The conduction component 16 includes a water pump 161, a slide 162 and an overflow port 164; the overflow port 164 is located at the top of the slide 162; one end of the water pump 161 is connected to the buffer water tank 17 through a hose, and the other end is connected to the overflow port 164 through a hose. The water pump 161 extracts the water inside the buffer water tank 17 and discharges it at the overflow port 164. Since the overflow port 164 is located at the top of the slide 162, the water discharged from the overflow port 164 forms a water flow on the slide 162, and the water flow enters the storage chamber 21 along the slide 162. The wax sheet cut by the cutting component 15 enters the interior of the slide 162, and then the wax sheet enters the storage chamber 21 along the slide 162 driven by the water flow.

[0065] Preferably, the conducting assembly 16 further includes a buffer chamber 163 ; the bottom of the buffer chamber 163 is connected to the water pump 161 via a hose; an overflow port 164 is provided at the top of the buffer chamber. The purpose of the buffer chamber 163 is to prevent excessive water flow from the water pump 161 from forming a fountain at the overflow port 164 and damaging the wax sheets.

[0066] A connecting pipe 24 is located at the bottom of the storage chamber 21, connecting the storage chamber 21 to the buffer water tank 17 via the connecting pipe 24. A connecting valve is mounted on the connecting pipe 24, which can selectively block the connecting pipe 24. Liquid level sensors are located on the inner walls of the storage chamber 21 and the inner walls of the buffer water tank 17. When the water level in the storage chamber 21 is too high or the water level in the buffer water tank 17 is too low, the connecting valve opens, allowing the liquid in the storage chamber 21 to enter the buffer water tank 17 through the connecting pipe 24. Once the water level in the buffer water tank 17 reaches the desired level, the connecting valve re-blocks the connecting pipe 24.

[0067] like Figure 4 As shown, a guide plate 221 is provided on the outside of the slide rail 22; a moving motor 31 is provided at the bottom of the robotic arm; a moving wheel 311 is provided on the output shaft of the moving motor 31; and the moving wheel 311 abuts against the guide plate 221. The moving motor 31 drives the moving wheel 311 to rotate, while the guide plate 221 remains stationary, and the moving wheel 311 drives the robotic arm to slide on the slide rail 22.

[0068] Specifically, the guide disc 221 is a gear disc, and the moving wheel 311 is a gear.

[0069] like Figure 4 、 6As shown, the collecting portion 2 includes a micro-motion tube 23. One end of the micro-motion tube 23 is connected to the bottom of the receiving chamber 21, and the other end is connected to the opening edge of the receiving chamber 21. A micro-motion pump is installed inside the micro-motion tube 23. The micro-motion pump sucks liquid from the bottom of the receiving chamber 21 and discharges it at the opening edge of the receiving chamber 21, thereby changing the direction of the water flow inside the receiving chamber 21 and changing the position of the wax flake on the liquid surface.

[0070] Specifically, the micro-motion tubes 23 are arranged in a circle with the receiving chamber 21 as the center. By turning on different micro-motion pumps, the direction of the water flow inside the receiving chamber 21 can be changed, thereby adjusting the position of the wax sheet on the liquid surface.

[0071] Specifically, eight groups of micro-motion tubes 23 are provided, and the eight groups of micro-motion tubes 23 are evenly arranged on the side wall of the receiving cavity 21 .

[0072] Preferably, a buffer chamber 211 is provided at the center of the bottom of the storage chamber 21. The top of the buffer chamber 211 is connected to the storage chamber 21, and the bottom is connected to the micro-motion tube 23 and the connecting tube 24. When the micro-motion pump draws liquid from the storage chamber 21, the liquid in the storage chamber 21 flows into the buffer chamber 211, generating a flow toward the center of the storage chamber 21, which drives the wax sheet toward the center of the storage chamber 21, thereby preventing the wax sheet from sticking to the inner wall of the storage chamber 21.

[0073] In some embodiments of the present application, a positioning camera 25 is provided at the opening of the storage chamber 21. The positioning camera 25 determines the position of the wax sheet by observing the difference in light reflection between the liquid surface and the wax sheet. The positioning camera 25 determines the relative position of the wax sheet and the working arm 35 and transmits this position information via wires to a processor. The processor activates various micropumps and controls the movement of the robotic arm to bring the glass slide 6 into proximity and retrieve the slice.

[0074] Preferably, the positioning cameras 25 are arranged in a circle with the storage cavity 21 as the center. Even if the scooping part 3 blocks a positioning camera 25 during operation, the other positioning cameras 25 can still determine the relative position of the wax sheet and the working arm.

[0075] like Figure 4 The shown motion assembly 14 includes a sliding member 141 and a sliding device; one end of the sliding member 141 is connected to the cutting assembly 15, and the other end is connected to the sliding device; the sliding device is fixed inside the cutting part 1.

[0076] Specifically, the sliding device is a sliding motor 142. The sliding motor 142 is a linear telescopic motor.

[0077] Alternatively, the sliding device includes a liquid tank, a sliding pump and a movable hydraulic rod; the liquid tank, the sliding pump and the movable hydraulic rod are all fixed inside the housing 11. The interior of the liquid tank is filled with hydraulic oil. One end of the sliding pump is connected to the liquid tank through a conduit, and the other end is connected to the movable hydraulic rod through a conduit. The output rod of the movable hydraulic rod is connected to the sliding member 141. The sliding pump can pump the hydraulic oil inside the liquid tank into the movable hydraulic rod, so that the output rod of the movable hydraulic rod extends; or pump the hydraulic oil inside the movable hydraulic rod into the liquid tank, so that the output rod of the movable hydraulic rod contracts. Therefore, the sliding pump can drive the output rod of the movable hydraulic rod to extend and retract, thereby driving the sliding member 141 to reciprocate along a straight line.

[0078] Preferably, the cutting part 1 is provided with a track along which the sliding member 141 moves. The track serves to limit the movement path of the sliding member 141 and prevent the sliding member 141 from deviating.

[0079] like Figure 7 As shown, the lifting assembly 13 includes a driving member 131 and a driving device; one end of the driving member 131 is connected to the driving device, and the other end is connected to the mounting member 132; the driving device is fixed inside the cutting part 1;

[0080] Specifically, the driving device and the driving motor 133. The driving motor 133 is a linear telescopic motor.

[0081] Alternatively, the driving device includes a storage bin, a driving pump, and a driving hydraulic rod; the storage bin, the driving pump, and the driving hydraulic rod are all fixed inside the housing 11. The interior of the storage bin is filled with hydraulic oil. One end of the driving pump is connected to the storage bin via a conduit, and the other end is connected to the movable hydraulic rod via a conduit. The output rod of the driving hydraulic rod is connected to the driving member 131. The driving pump can pump the hydraulic oil inside the storage bin into the driving hydraulic rod, causing the output rod of the driving hydraulic rod to extend; or pump the hydraulic oil inside the driving hydraulic rod into the storage bin, causing the output rod of the driving hydraulic rod to retract. Therefore, the driving pump can drive the output rod of the driving hydraulic rod to extend and retract, thereby driving the driving member 131 to reciprocate along a straight line.

[0082] Preferably, a slide groove 111 is provided on the cutting portion 1, and the driving member 131 moves along the slide groove 111. The function of the slide groove 111 is to limit the moving path of the driving member 131 and prevent the driving member 131 from deviating.

[0083] like Figure 8 As shown, the cutting assembly 15 includes a fixed frame 151, a movable frame 152, and a blade 153. One end of the fixed frame 151 is fixedly connected to the moving assembly 14. The fixed frame 151 and the movable frame 152 are detachably connected. The movable frame 152 presses the blade 153 against the side wall of the fixed frame 151. The movable frame 152 has an internal clearance groove to allow the wax block to contact the blade 153, allowing the blade 153 to gradually cut the wax block into wax slices.

[0084] Specifically, the fixed frame 151 and the movable frame 152 are connected by bolts.

[0085] like Figure 9-10 As shown, the robotic arm includes a sliding frame 33, a rotating arm 32 and a connecting arm 34; a steering motor 321 is provided on the sliding frame 33; the output shaft of the steering motor 321 is connected to the rotating arm 32; a rotating motor is provided at the end of the rotating arm 32 away from the sliding frame 33; the output shaft of the rotating motor is connected to the connecting arm 34; a reversing motor is provided at the end of the connecting arm 34 away from the rotating arm 32; the output shaft of the reversing motor is connected to the working arm 35.

[0086] The workflow of this embodiment is as follows:

[0087] 1. The robotic arm moves so that the gripper 36 is aligned with the slide placement area 4, so that the gripper 36 grips a slide 6;

[0088] 2. The lifting assembly 13 moves downward, driving the wax block to contact the blade 153, and the blade 153 cuts a wax sheet from the wax block;

[0089] 3. The wax sheet enters the slide 162 and is carried into the storage chamber 21 by the water flow inside the slide 162;

[0090] 4. The camera determines the relative position of the wax sheet and the working arm 35, and sends the position information to the processor via a wire. The processor controls different micro pumps to open to prevent the wax sheet from sticking to the inner wall of the storage chamber 21;

[0091] 5. The processor controls the movement of the robotic arm, which drives the working arm 35 to insert the glass slide 6 on the gripper 36 into the liquid. The robotic arm then guides the camera 353 to find the wax piece. The robotic arm drives the glass slide 6 to the bottom of the wax piece. The robotic arm drives the working arm 35 to continue to sink into the liquid surface, so that the limit piece 356 surrounds the wax piece. The motor 354 is then turned to drive the gripper 36 to rotate, causing the glass slide 6 to rotate and gradually approach the liquid surface. Finally, the glass slide 6 is driven to pick up the wax piece, obtaining a finished product with a wax piece.

[0092] 6. The robotic arm moves and places the finished product into the finished product placement area 5;

[0093] 7. Repeat 1-6 until there is no more glass slide 6 inside the glass slide placement area 4.
