Description

Technical Field

[0001] This utility model relates to the field of slice scanning equipment technology, and in particular to a scanner. Background Technology

[0002] A pathology slide scanner is a medical device that uses high-resolution digital imaging technology to convert traditional glass slides into digital pathology slides. In practice, to avoid the pathology slides being affected by the external environment during scanning, a sealed scanner body is usually used, and the pathology slides are placed inside the scanner's internal chamber for scanning. This means that the scanner's circuit boards, various drive structures, scanning lenses, and connecting circuits are basically integrated inside the machine. However, during the operation of these components, especially the circuit boards which contain many heat-generating elements, these elements heat the air inside the chamber, causing the temperature inside the chamber to rise. This, in turn, affects the pathology slides and impacts the overall scanning results.

[0003] To ensure the airtightness of the machine body, the design of opening air vents on the side wall of the machine body for cooling is not feasible. In the existing technology, the common methods are overall liquid cooling or external fans blowing air onto the heat-generating parts of the machine body. Overall liquid cooling design requires complex equipment, is complicated to install and has high cost, while external fan cooling has low heat dissipation efficiency and cannot achieve effective cooling. Utility Model Content

[0004] The purpose of this invention is to provide a scanner that can achieve effective cooling and heat dissipation while ensuring that the scanner's internal structure is sealed.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A scanner is provided, including a body, a circuit board, a media supply assembly, and a cooling plate. The media supply assembly is disposed on the outside of the body and connected to an external cooling device. The circuit board and the cooling plate are disposed inside the cavity of the body. One side of the cooling plate along its thickness direction is used to bond to the circuit board with thermally conductive adhesive. The cooling plate has a cooling channel for the flow of cooling medium. The two ends of the cooling channel are respectively provided with a media inlet and a media outlet connected to the outside of the body. The media inlet and / or the media outlet are connected to the media supply assembly.

[0007] In one embodiment, a flow guide layer is provided at one end of the cooling plate away from the circuit board, and an air flow channel is provided in the flow guide layer. An air inlet and an air outlet communicating with the inner cavity of the scanner are respectively provided at both ends of the air flow channel.

[0008] In one embodiment, the cooling plate is further provided with a flow guide fan, which is disposed at the air inlet and / or the air outlet.

[0009] In one embodiment, the airflow path gradually increases along the direction from the air inlet to the air outlet.

[0010] In one embodiment, the media supply assembly includes a cooling fan disposed at the media inlet and / or the media outlet.

[0011] In one embodiment, the medium supply assembly includes a liquid-cooled water tank, which includes an outlet connected to the medium inlet and a return water end connected to the medium outlet.

[0012] In one embodiment, the scanner further includes a feeding assembly, which includes a drive structure and a tray holder for placing a tray, the drive structure being kinetically connected to the tray holder to drive the tray holder to lift and lower.

[0013] A feeding chamber door is provided on one side wall of the machine body adjacent to the pallet frame. The machine body is also provided with a scanning platform and a limiting baffle. The limiting baffle is located on the side of the pallet frame away from the feeding chamber door and is located between the scanning platform and the pallet frame. The limiting baffle has a feeding port that penetrates the limiting baffle along its thickness direction. The upper and lower edges of the feeding port facing the pallet frame are provided with a first chamfered surface, and the end of the pallet facing the feeding port is provided with a second chamfered surface.

[0014] In one embodiment, the limiting baffle is provided with a limiting sensor for sensing the pallet on the side opposite to the pallet frame.

[0015] In one embodiment, the tray includes a body with a plurality of placement slots for placing pathological slides. The body also has an opening clamping assembly, which includes a drive member, a transmission rod, and a clamping block. The clamping block has a first position and a second position. When the clamping block is in the first position, it is at least partially located above the placement slots and within the horizontal projection range of the pathological slides. When the clamping block is in the second position, it is located outside the horizontal projection range of the pathological slides. The drive member is connected to the clamping block via the transmission rod to drive the clamping block to move between the first position and the second position.

[0016] In one embodiment, the drive element includes a cam and a return spring. The cam is throttle connected to the transmission rod and drives the transmission rod to move along its axial direction, thereby moving the clamping block between the first position and the second position.

[0017] The return spring is connected to the clamping block and / or the transmission rod and has a tendency to move the clamping block toward the first position.

[0018] The beneficial effects of this utility model are:

[0019] This invention discloses a cooling mechanism comprising a media supply assembly disposed on the outside of the scanner and a cooling plate disposed within the scanner cavity. The media supply assembly communicates with cooling channels within the cooling plate, allowing cooling media to be input into the cooling channels and exchange heat with a circuit board bonded to the cooling plate, thereby cooling the circuit board. By providing a closed cooling channel within the cooling plate, the circuit board within the scanner can be effectively cooled while maintaining the scanner's airtightness. This reduces overheating of the heating elements on the circuit board and also reduces the heating of the air inside the cavity by the heating elements, preventing excessively high internal temperatures from affecting the scanning results of pathological sections.

[0040] Example 1

[0041] like Figures 1 to 12 As shown, a scanner according to this embodiment includes a body 1, a circuit board 2, a media supply assembly, and a cooling plate 200. The media supply assembly is disposed on the outside of the body 1 and connected to an external cooling device. The circuit board 2 and the cooling plate 200 are disposed in the inner cavity 11 of the body 1. One side of the cooling plate 200 along its thickness direction is used to bond to the circuit board 2 disposed in the inner cavity 11 by thermally conductive adhesive 3. The cooling plate 200 is provided with a cooling channel 210 for the flow of cooling medium. The two ends of the cooling channel 210 are respectively provided with a media inlet 211 and a media outlet 212 communicating with the outside of the body 1. The media inlet 211 and / or the media outlet 212 are connected to the media supply assembly.

[0042] In this embodiment, by placing the media supply component on the outside of the body 1 and connecting it to an external cooling device, a cooling medium is introduced into the cooling channel 210 of the cooling plate 200 located in the inner cavity 11 of the body 1. Heat exchange occurs between the cooling plate 200 and the circuit board 2 bonded to it, thereby cooling the circuit board 2. A cooling medium circulation channel isolated from the inner cavity 11 is formed between the media supply component and the cooling plate 200. This effectively cools the circuit board 2 inside the body 1 while maintaining the airtightness of the body 1, reducing overheating of the heating element 21 on the circuit board 2 and minimizing the heating of the air inside the inner cavity 11 by the heating element 21. This prevents the temperature inside the body 11 from becoming too high and affecting the scanning results of the pathological slide 5.

[0043] Specifically, such as Figure 1 and Figure 5 As shown, the cooling channel 210 located directly below the heating element 21 is arranged in a serpentine or S-shape to increase the heat exchange time between the cooling medium and the heating element 21 and improve the cooling efficiency of the cooling medium on the heating element 21.

[0044] In this embodiment, the medium supply component includes a cooling fan 110, which is disposed at the medium inlet 211 and / or the medium outlet 212. That is, at least one cooling fan 110 is disposed at the medium inlet 211 and the medium outlet 212, so that external cold air is input from the medium inlet 211 toward the cooling channel 210 through the cooling fan 110, and the air in the cooling channel 210 after heat exchange with the circuit board 2 flows out from the medium outlet 212.

[0045] In practical operation, the medium inlet 211 can also be connected to an external air conditioning outlet to input cooling air into the cooling channel 210, thereby improving the cooling efficiency of the cooling plate 200. Simultaneously, a cooling fan 110 is installed at the medium outlet 212 to increase the airflow velocity within the cooling channel 210, further enhancing the cooling efficiency of the cooling plate 200. Such designs are all within the protection scope of this utility model.

[0046] In one embodiment, a flow guide layer 220 is provided at the end of the cooling plate 200 facing away from the circuit board 2. An airflow channel 221 is provided within the flow guide layer 220. An air inlet 222 and an air outlet 223, respectively, are provided at both ends of the airflow channel 221, communicating with the inner cavity 11 of the body 1. This allows air inside the inner cavity 11 to circulate through the airflow channel 221, achieving cooling and heat dissipation. Specifically, air from the inner cavity 11 enters the airflow channel 221 through the air inlet 222 and exchanges heat with the cooling medium in the cooling plate 200 within the airflow channel 221 to achieve cooling. The cooled air then returns to the inner cavity 11 through the air outlet 223, thereby facilitating the cooling of the inner cavity 11.

[0047] By connecting both the air inlet 222 and the air outlet 223 to the inner cavity 11, the internal air of the inner cavity 11 is circulated and cooled, avoiding the introduction of external air and thus preventing the introduction of dust and other impurities from the outside, which helps to ensure the safety of the pathological slide 5.

[0048] In one embodiment, the cooling plate 200 is further provided with a guide fan 230, which is located at the air inlet 222 and / or the air outlet 223. This guide fan 230 increases the airflow speed within the airflow channel 221, thereby improving cooling efficiency. Furthermore, the air inlet 222 and the air outlet 223 are respectively located on opposite sides of the cooling plate 200. The air inlet 222 is located at one end of the cooling plate 200 adjacent to the scanning platform 6 within the scanner 1, and the air outlet 223 is located at the end of the cooling plate 200 away from the scanning platform 6. This prevents air from blowing directly onto the scanning platform 6 through the air outlet 223, which could cause excessive wind speed at the scanning platform 6 and thus affect the scanning operation of the pathological slides 5 located on the scanning platform 6.

[0049] In one embodiment, the airflow path 221 gradually increases in the direction from the air inlet 222 to the air outlet 223 to increase the heat exchange time and area between the air and the cooling medium in the cooling plate 200, thereby improving the cooling efficiency of the cooling medium on the air in the inner cavity 11.

[0050] In one embodiment, the scanner further includes a feeding assembly 4, which includes a drive structure 41 and a tray frame 43 for placing a tray 42. The drive structure 41 is driven by the tray frame 43 to drive the tray frame 43 to rise and fall, thereby conveying the tray 42, on which the pathological slide 5 is placed. Specifically, the drive structure 41 includes a fixed bracket 4101, on which a drive motor 4102 is mounted. A connecting member 4104 is driven by the drive shaft 4103 of the drive motor 4102. The connecting member 4104 is fixedly connected to the tray frame 43, thereby driving the tray frame 43 to rise and fall along the axial direction of the drive shaft 4103 via the drive motor 4102.

[0051] The machine body 1 has a feeding door 12 located on one side wall adjacent to the pallet rack 43. Operators open the feeding door 12 and place the pallet 42 onto the pallet rack 43. The machine body 1 also includes a scanning platform 6 and a limiting baffle 7. The limiting baffle 7 is located on the side of the pallet rack 43 opposite to the feeding door 12 and is positioned between the scanning platform 6 and the pallet rack 43. It helps to limit the position of the pallet 42 when the operator places it, ensuring accurate placement. The limiting baffle 7 has a feeding port 71 that extends through it along its thickness. The driving structure 41 transports the corresponding pallet 42 to the feeding port 71, and then the pallet 42 is transported from the feeding port 71 to the scanning platform 6 for scanning.

[0052] Furthermore, such as Figure 10As shown, the upper and lower edges of the feed inlet 71 facing the tray frame 43 are provided with a first chamfer surface 72, and the end of the tray 42 facing the feed inlet 71 is provided with a second chamfer surface 4201. The tray 42 has a second chamfer surface 4201 respectively provided along its thickness direction facing the upper and lower edges of the feed inlet 71. When the tray 42 enters from the feed inlet 71, it collides with the upper or lower edge of the feed inlet 71. The contact between the first chamfer surface 72 and the second chamfer surface 4201 can reduce the impact between the tray 42 and the limiting baffle 7. Under the action of the first chamfer surface 72 and the second chamfer surface 4201, the tray 42 can still smoothly enter the scanning platform 6 from the feed inlet 71.

[0053] Furthermore, when the material feeding position of the pallet 42 is too deep and enters the feed inlet 71 but does not exceed the limit baffle 7, during the process of the drive structure 41 driving the pallet 42 to rise and fall, due to the action of the first chamfered surface 72 and the second chamfered surface 4201, the pallet 42 can be smoothly moved out of the feed inlet 71 during the rising or falling process, avoiding interference between the pallet 42 and the limit baffle 7.

[0054] Furthermore, the limiting baffle 7 is provided with a third chamfered surface 73 at both ends along the lifting direction of the pallet 42. Thus, when the pallet 42 is located outside the upper and lower ends of the limiting baffle 7 and part of the pallet 42 is located within the horizontal projection range of the limiting baffle 7, when the driving structure 41 drives the pallet 42 to move up and down, the third chamfered surface 73 and the second chamfered surface 4201 can ensure that the pallet 42 moves out of the horizontal projection range of the limiting baffle 7, thus avoiding interference between the pallet 42 and the limiting baffle 7.

[0055] In one embodiment, a limit sensor 74 for sensing the pallet 42 is provided on the side of the limit baffle 7 away from the pallet frame 43. When the pallet 42 is placed into the pallet frame 43, if the pallet 42 exceeds the position of the limit baffle 7, the limit sensor 74 will detect that the position of the pallet 42 exceeds the limit and issue an alarm. The operator can only proceed to the next step after readjusting the position of the pallet 42. This helps to avoid interference between the position of the pallet 42 and the limit baffle 7 when the drive structure 41 drives the pallet frame 43 to move the pallet 42.

[0056] In one embodiment, the tray 42 includes a body 4202 with a plurality of placement slots 4203 for placing pathological slides 5. The body 4202 also includes an opening and closing assembly 8, which includes a drive member 81, a transmission rod 82, and a clamping block 83. The clamping block 83 has a first position and a second position. When the clamping block 83 is in the first position, it is at least partially located above the placement slots 4203 and within the horizontal projection range of the pathological slides 5, thus clamping and fixing the pathological slides 5 within the placement slots 4203. When the clamping block 83 is in the second position, it is located outside the horizontal projection range of the pathological slides 5. Specifically, at this time, the clamping block 83 is outside the horizontal projection range of the placement slots 4203, allowing the pathological slides 5 to be removed or placed. The drive member 81 is connected to the clamping block 83 via the transmission rod 82 to drive the clamping block 83 to move between the first and second positions, thereby clamping or releasing the pathological slides 5.

[0057] Furthermore, the drive component 81 includes a cam 8101 and a return spring 8102. The cam 8101 is driveably connected to the transmission rod 82. By rotating the cam 8101, the transmission rod 82 is moved along its axial direction, which in turn moves the clamping block 83 along the axial direction of the transmission shaft 4103 to reach a first position and a second position. The return spring 8102 is connected to the clamping block 83 and / or the transmission rod 82 and has a tendency to move the clamping block 83 toward the first position.

[0058] Furthermore, in this embodiment, two clamping blocks 83 are provided, respectively disposed on both sides of the placement groove 4203, to ensure stable clamping of the pathological slide 5. The cam 8101 is configured with an elliptical horizontal projection plane, so that when the cam 8101 is rotated, it simultaneously pushes the two transmission rods 82 to move, thereby moving the clamping blocks 83 on both sides, achieving synchronized opening or closing operations, which is simple and convenient to operate.

[0059] Example 2

[0060] like Figure 13As shown, the difference between this embodiment and Embodiment 1 is that the medium supply component in this embodiment includes a liquid-cooled water tank 120. The water tank includes an outlet 121 connected to the medium inlet 211 and a return water end 122 connected to the medium outlet 212. Coolant at a lower temperature is input into the cooling channel 210 through the outlet 121 via the medium inlet 211, and the coolant at a higher temperature after heat exchange is recovered and cooled again through the return water end 122. This achieves the circulation of coolant within the cooling channel 210, thereby cooling the circuit board 2 by the cooling plate 200. In this embodiment, the liquid cooling method provides higher cooling efficiency compared to the air-cooled method. Furthermore, the other structural features of this embodiment are identical to those of Embodiment 1 and will not be described again here.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
